Detailed ways

Reference will now be made in detail to the exemplary embodiments, examples of which are illustrated in the accompanying drawings. When the following description refers to the accompanying drawings, the same numerals in different drawings refer to the same or similar elements unless otherwise indicated. The implementations described in the following exemplary examples do not represent all implementations consistent with the present disclosure. Rather, they are merely examples of apparatuses and methods consistent with aspects of the present disclosure as recited in the appended claims.

For the convenience of description, some concepts involved in the present disclosure are firstly explained below.

Fig. 1 is a schematic diagram showing an application scenario of a random access method according to an exemplary embodiment. The application scenario is a communication system, which includes but is not limited to Global System of Mobile communication (Global System of Mobile communication, GSM), General Packet Radio Service (General Packet Radio Service, GPRS) system, Long Term Evolution (Long Term Evolution, LTE) system, etc.

As shown in Figure 1, the application scenario includes a base station and user equipment. User equipment includes, but is not limited to, mobile phones (cellphones), smart phones (smartphones), computers (computers), tablet computers, personal digital assistants (personal digital assistants, PDAs), mobile Internet devices, wearable devices, and the like. The base station includes but is not limited to a base station (Base Transceiver Station, BTS) in GSM, an evolved base station (evolutional NodeB, eNB) in LTE, and the like.

When the user equipment needs to start communication with the base station, the user equipment sends a random access message to the base station with initial transmit power. If the transmit power is too low so that the base station cannot receive the random access message, the base station will not send the response message of the random access message to the user equipment. Correspondingly, the user equipment cannot receive the response message of the random access message from the base station. At this time, the user equipment needs to increase the transmit power, and send the random access message to the base station again with the increased transmit power.

If the user equipment does not receive a response message from the base station even though the user equipment increases the transmission power to the maximum transmission power allowed by itself and sends a random access message to the base station with the maximum transmission power, the user equipment always uses the maximum transmission power The transmission power sends a random access message to the base station until a response message is received from the base station, or the number of times of sending the random access message reaches the maximum number of attempts.

In some technologies, the user equipment sends a random access message to the base station through an antenna, and if no response message is received from the base station, it continues to send the random access message to the base station through the antenna with increased transmit power, Until a response message is received from the base station, or the number of times of sending random access messages reaches the maximum number of attempts.

However, in the case that the user equipment sends a random access message to the base station with a suitable transmission power through the antenna, if the antenna is interfered, the base station may not be able to receive the random access message, which makes it impossible for the user equipment to establish with the base station connection, so that the user equipment cannot use the network service provided by the base station.

In addition, in any one or more of the following situations, the performance of the antenna of the user equipment may be interfered: the user holds the user equipment, the user blocks the user equipment, and the items worn/carried by the user are made of metal 1. If the user carries other electronic equipment, the back shell of the user equipment is made of metal.

In some technologies, the user equipment sends a random access message to the base station through an antenna, and if it does not receive a response message from the base station, it continues to send a random access message to the base station through the antenna with increased transmit power. If the user equipment increases the transmission power to the maximum transmission power allowed by itself and sends a random access message to the base station with the maximum transmission power, it still does not receive a response message from the base station, then the user equipment passes another The antenna sends a random access message to the base station.

However, the process of sending random access messages before the transmission power reaches the maximum transmission power is useless, which wastes time and resources of the user equipment, increases communication delay and power consumption of the user equipment, and reduces the standby time.

Embodiments of the present disclosure will be explained below in conjunction with the accompanying drawings.

Fig. 2 is a flowchart showing a random access method according to an exemplary embodiment. The random access method may be applied to user equipment, for example, the random access method may be applied to the user equipment in Fig. 1 . As shown in Fig. 2, the random access method may include the following steps.

In step S211, a random access message is sent to the base station with an initial transmit power through one of the multiple antennas included in the user equipment.

In this embodiment, the user equipment may include multiple antennas. For example, the user equipment includes 2 to 4 antennas. In another example, the user equipment is a 5G mobile phone, and the user equipment includes 64 antennas. The user equipment can send a random access message to the base station with initial transmit power through any one of the multiple antennas included in the user equipment.

In this embodiment, when the user equipment performs network search, the user equipment starts to monitor the system information broadcast by the base station, where the system information includes the initial transmission power. For example, a system information block (SystemInformationBlock, SIB) type 5 or SIB type 6 broadcast by the base station includes system information. Therefore, the user equipment can obtain the initial transmission power by obtaining the system message.

In step S213, it is judged whether a response message to the random access message sent by the base station is received.

If the judgment is "Yes", the following step S217 is executed. On the contrary, if the judgment is "No", then the following step S215 will be performed. That is to say, if the random access message is successfully sent to the base station with the initial transmission power through the currently used antenna, the following step S217 is performed. Correspondingly, if sending the random access message to the base station with the initial transmission power through the currently used antenna fails, the following step S215 is performed.

In step S215, a random access message is sent to the base station with a first transmit power greater than the initial transmit power through another antenna among the multiple antennas, and then step S213 is continued.

As mentioned above, in the related art, the currently used antenna is always used to send random access messages to the base station, or the currently used antenna is always used before the transmit power reaches the maximum transmit power, and after the transmit power reaches the maximum transmit power Switch the currently used antenna to another antenna.

In contrast, in this embodiment, if the currently used antenna fails to send a random access message to the base station at the initial transmit power, the currently used antenna is immediately switched to another antenna, and at the initial transmit power Increase the transmit power on the basis of the antenna, and continue to send the random access message to the base station through the other antenna with the increased transmit power. Wherein, the other antenna is any antenna among the multiple antennas included in the user equipment except the currently used antenna.

In step S217, stop sending random access messages to the base station.

Therefore, in the embodiments of the present disclosure, as long as the currently used antenna fails to send a random access message to the base station, the currently used antenna is switched to an antenna different from the currently used antenna, and the switched antenna is used. antennas to continue sending random access messages to the base station, thus, by switching antennas in time, it is possible to avoid using the interfered or covered antenna to send random access messages to the base station all the time, thus improving the efficiency of sending random access messages to the base station The success rate is high, the communication delay is reduced, the power consumption of the user equipment is saved, and the standby time of the user equipment is extended.

Embodiments of the present disclosure are described below by taking the user equipment including three antennas as an example. Assuming that the numbers of the three antennas are 1, 2 and 3 respectively, the user equipment performs the following processing: the user equipment sends a random access message to the base station with an initial transmission power through antenna 1. Then, the user equipment judges whether to receive the response message of the random access message. If it is determined that no response message is received, the user equipment sends a random access message to the base station through the antenna 2 with a transmission power (first transmission power) greater than the initial transmission power.

Then, the user equipment judges whether to receive the response message of the random access message. If it is determined that no response message has been received, the user equipment uses antenna 3 to transmit a random access message to the base station with a transmission power (the current first transmit power) to send a random access message to the base station.

Then, the user equipment judges whether to receive the response message of the random access message. If it is determined that no response message is received, the user equipment sends a random access message to the base station through antenna 2 with a transmission power greater than that used for sending the random access message to the base station through antenna 3, and so on, until A response message to the random access message is received.

Fig. 3 is a flowchart showing an example of a random access method according to an exemplary embodiment, the random access method can be applied to user equipment, for example, the random access method can be applied to the user in Fig. 1 equipment. As shown in Fig. 3, the random access method may include the following steps.

In step S311, a random access message is sent to the base station with an initial transmission power through one of the multiple antennas included in the user equipment, and the number of times of sending the random access message is increased by 1.

In this embodiment, the initial value of the sending times is 0. The maximum number of attempts indicates the maximum number of times that the user equipment can try to send the random access message to the base station. For example, if the maximum number of attempts is 3, it means that the user equipment can send random access messages to the base station three times at most. The system message may also include a maximum number of attempts, and the user equipment may acquire the maximum number of attempts by obtaining the system message.

In step S312, it is judged whether a response message to the random access message sent by the base station is received. If the judgment is "Yes", the following step S315 is executed. On the contrary, if the determination is "No", the following step S313 will be executed.

In step S313, it is judged whether the number of times of sending is equal to the maximum number of times of attempts sent by the base station to the user equipment through broadcasting. If the judgment is "Yes", the following step S315 is executed. On the contrary, if the determination is "No", the following step S314 is executed.

In step S314, a random access message is sent to the base station with the first transmission power through another antenna, and the number of times of sending the random access message is increased by 1, and then step S312 is continued.

In a possible implementation, the first transmit power is calculated according to the formula P ₁ =P ₀ +N×ΔP, where P ₁ is the first transmit power, P ₀ is the initial transmit power, N is the number of times of transmission, and ΔP is The base station transmits the power ramp-up step size to the user equipment by broadcasting.

In this embodiment, the system message may also include a power ramp-up step, and the user equipment may obtain the power ramp-up step by acquiring the system message.

In step S315, stop sending random access messages to the base station.

Therefore, in the embodiments of the present disclosure, as long as the currently used antenna fails to send a random access message to the base station, the currently used antenna is switched to an antenna different from the currently used antenna, and the switched antenna is used. antennas to continue sending random access messages to the base station, thus, by switching antennas in time, it is possible to avoid using the interfered or covered antenna to send random access messages to the base station all the time, thus improving the efficiency of sending random access messages to the base station The success rate is high, the communication delay is reduced, the power consumption of the user equipment is saved, and the standby time of the user equipment is extended.

The following uses an example in which the user equipment includes three antennas and the maximum number of attempts is 2 to illustrate the embodiments of the present disclosure. Assuming that the numbers of the three antennas are 1, 2, and 3 respectively, the user equipment performs the following processing: the user equipment sends a random access message to the base station with the initial transmission power through antenna 1, and increases the number of times of sending by 1, and the number of times of sending is 1.

Then, the user equipment judges whether to receive the response message of the random access message. If it is determined that no response message is received, the user equipment determines whether the number of sending times is equal to the maximum number of attempts. At this time, the user equipment determines that the number of times of sending 1 is less than the maximum number of attempts 2, and the user equipment sends a random access message to the base station with a transmission power (first transmission power) greater than the initial transmission power through the antenna 2, and increases the number of times of sending to the base station. 1. At this time, the number of sending is 2.

Next, the user equipment judges whether the response message of the random access message is received. If it is determined that no response message is received, the user equipment determines whether the number of sending times is equal to the maximum number of attempts. At this time, the user equipment determines that the number of sending times 2 is equal to the maximum number of attempts 2, and the user equipment stops sending the random access message to the base station.

Fig. 4 is a flowchart showing an example of a random access method according to an exemplary embodiment, the random access method can be applied to user equipment, for example, the random access method can be applied to the user in Fig. 1 equipment. As shown in Fig. 4, the random access method may include the following steps.

In step S411, a random access message is sent to the base station with an initial transmit power through one of the multiple antennas included in the user equipment. For specific descriptions, reference may be made to the foregoing description of step S211 , which will not be repeated here.

In step S412, it is judged whether a response message to the random access message sent by the base station is received. If the judgment is "Yes", the following step S415 is executed. On the contrary, if the determination is "No", the following step S413 is executed.

In step S413, it is judged whether the first transmit power is greater than or equal to the maximum transmit power of the user equipment. If the judgment is "Yes", the following step S415 is executed. On the contrary, if the determination is "No", the following step S414 is performed.

In this embodiment, the maximum transmit power is the maximum withstand power of the antenna of the user equipment, and the maximum transmit power is one of performance indicators of the antenna of the user equipment.

In step S414, send a random access message to the base station with the first transmission power through another antenna, and then continue to execute step S412.

In step S415, stop sending random access messages to the base station.

Therefore, in the embodiments of the present disclosure, as long as the currently used antenna fails to send a random access message to the base station, the currently used antenna is switched to an antenna different from the currently used antenna, and the switched antenna is used. antennas to continue sending random access messages to the base station, thus, by switching antennas in time, it is possible to avoid using the interfered or covered antenna to send random access messages to the base station all the time, thus improving the efficiency of sending random access messages to the base station The success rate is high, the communication delay is reduced, the power consumption of the user equipment is saved, and the standby time of the user equipment is extended.

Moreover, if sending random access messages to the base station with the maximum transmit power fails, subsequent random access messages sent to the base station with the maximum transmit power may also fail, which increases the power consumption of the user equipment. Therefore, in this In the disclosed embodiment, when sending the random access message to the base station with the maximum transmission power fails for the first time, the sending of the random access message to the base station is stopped, so that the power consumption of the user equipment can be saved and the standby time of the user equipment can be extended.

Fig. 5 is a block diagram showing a random access apparatus according to an exemplary embodiment, and the random access apparatus may be applied to a user equipment UE. Referring to FIG. 5 , the random access device 500 includes a sending module 121 and a judging module 123 .

The judging module 123 is configured to judge whether a response message to the random access message sent by the base station is received.

When the judging module 123 judges that no response message has been received, the sending module 121 sends a random access message to the base station with a first transmit power greater than the initial transmit power through another antenna in the multiple antennas, and then the judging module 123 Continue to judge whether the response message of the random access message is received.

In a possible implementation manner, the random access apparatus 500 may further include: a counting module (not shown), configured to add 1 to the number of times the random access message is sent each time the random access message is sent to the base station, Correspondingly, the judging module 123 is further configured to judge whether the number of times of sending is equal to the maximum number of times of attempts sent by the base station to the UE through broadcasting when it is judged that no response message is received. When it is determined that the number of transmissions is less than the maximum number of attempts, the sending module 121 sends a random access message to the base station with the first transmission power through another antenna, and then the judging module 123 continues to judge whether a response message to the random access message is received . When it is determined that the number of sending times is equal to the maximum number of attempts, the sending module 121 stops sending the random access message to the base station.

In a possible implementation, the first transmit power is calculated according to the formula P ₁ =P ₀ +N×ΔP, where P ₁ is the first transmit power, P ₀ is the initial transmit power, N is the number of times of transmission, and ΔP is The base station broadcasts the power ramping step size sent to the UE.

In a possible implementation manner, the judging module 123 is further configured to judge whether the first transmit power is greater than or equal to the maximum transmit power of the UE when it is judged that no response message is received. When it is determined that the first transmit power is less than the maximum transmit power, the sending module 121 sends a random access message to the base station with the first transmit power through another antenna, and then the judging module 123 continues to judge whether the random access message is received. Respond to the message. When it is determined that the first transmission power is greater than or equal to the maximum transmission power, the sending module 121 stops sending the random access message to the base station.

In a possible implementation manner, when it is determined that the response message is received, the sending module 121 stops sending the random access message to the base station.
