FIG. 1 is a schematic flowchart of a wireless communication method provided in Embodiment 1 of the present application. In this embodiment, the network equipment in the communication cell, which is a network control node in this embodiment, such as a radio network controller (Radio Network Controller, RNC), can send uplink carrier configuration information to mobile terminals in the cell through the cell base station, so that The mobile terminal can send uplink data based on the configuration information. Specifically, as shown in FIG. 1, the method in this embodiment may include the following steps:

Step 101, the network control node determines the uplink carrier configuration information of the uplink channel in the cell, the uplink carrier configuration information includes at least one uplink subcarrier, and the bandwidth of the at least one uplink subcarrier is smaller than the bandwidth of the downlink carrier of the downlink channel of the cell;

Step 102, the network control node sends uplink carrier configuration information to the mobile terminal, so that the mobile terminal determines one uplink subcarrier from the at least one uplink subcarrier to transmit uplink data.

In this embodiment, the configuration information sent by the network control node in step 102 may include multiple or one uplink subcarriers. When the configuration information received by the mobile terminal includes multiple uplink subcarriers, the mobile terminal may randomly Determine an uplink subcarrier to transmit uplink data, or determine an uplink and downlink subcarrier based on historically used uplink subcarrier information or other information; and when the mobile terminal receives the configuration information that only includes one uplink subcarrier, it will The one uplink subcarrier can be directly used to send uplink data.

In this embodiment, the data uploaded by the mobile terminal in step 102 may specifically include information such as a random access preamble (Preamble), uplink signaling, or uplink services.

In this embodiment, the uplink carrier configuration information of the uplink channel in the cell can be pre-configured on the network control node, and the uplink carrier configuration information can include at least one of the following information: the number of uplink subcarriers, the frequency point of each uplink subcarrier , the index number of each uplink subcarrier, and the bandwidth of the uplink subcarrier and other information. Those skilled in the art can understand that the uplink subcarrier bandwidth refers to the frequency range representation of the uplink subcarrier in the communication system.

Specifically, the above-mentioned uplink subcarriers may specifically refer to information including frequency points and bandwidth sizes, or may also refer to information including frequency points, bandwidth sizes, and subcarrier index numbers, etc.; or may also refer to information including uplink Information about the number of subcarriers and subcarrier index numbers; or, it may also be a list of frequency points including uplink subcarriers; or, when the network control node has sent uplink carrier configuration information to the mobile terminal, and indicates the number of uplink subcarriers After the information includes the carrier index number, the network control node may also only send the carrier index number used to indicate the uplink sub-carrier to the mobile terminal.

In the wireless communication method provided in this embodiment, the mobile terminal can transmit uplink data based on the uplink subcarriers in the uplink carrier configuration information, and the bandwidth of the uplink subcarriers is smaller than the bandwidth of the downlink carrier. In this way, in a communication cell, the mobile terminal The uplink data can be sent on the uplink sub-carriers with small bandwidth, so as to improve the throughput of uplink data and the performance of the communication system. At the same time, it can also avoid the existing problems caused by dividing large bandwidth cells into small bandwidth cells. System maintenance and resource waste.

Wherein, the transmission time interval information of uplink subcarriers and/or downlink subcarriers may be configured with different values for different channels, and the transmission time intervals of uplink subcarriers and downlink subcarriers may be the same or different. For example, if there are 2 uplink subcarriers and 1 downlink carrier, and the bandwidth of the downlink carrier is greater than the bandwidth of the 2 uplink subcarriers, the following configuration can be performed: the length of the downlink wireless frame is 10 ms, and the downlink high-speed downlink shared channel (High SpeedDownlink Shared Channel, referred to as HS-DSCH) subframe is 2ms, uplink dedicated physical control channel (Dedicated Physical Control Channel, referred to as DPCCH), uplink dedicated physical data channel (Dedicated Physical Data Channel, referred to as DPDCH), high-speed dedicated physical control channel High Speed Dedicated Physical Control Channel (HS-DPCCH for short), Enhanced Dedicated Physical Data Channel (E-DPDCH for short), and Enhanced Dedicated Physical Control Channel (E-DPCCH for short) minimum TTI The subframe is 4ms, the period of 15 random access slots is 40ms, and the length of the radio frame is 20ms.

When the UE receives the uplink carrier configuration information, it may perform uplink access or downlink reception according to the length of the radio frame or subframe. FIG. 2 is a schematic flowchart of a wireless communication method provided in Embodiment 2 of the present application. As shown in Figure 2, the wireless communication method of this embodiment may include the following steps:

Step 201, the network control node determines the uplink carrier configuration information of the uplink channel in the cell, the uplink carrier configuration information includes at least one uplink subcarrier and subcarrier indication information corresponding to the uplink subcarrier, wherein the bandwidth of the at least one uplink subcarrier is less than The bandwidth of the downlink carrier of the downlink channel of the cell, and the subcarrier indication information is used to indicate the state of the uplink subcarrier;

Step 202, the network control node sends uplink carrier configuration information to the mobile terminal, so that the mobile terminal can determine an uplink subcarrier among at least one uplink subcarrier based on the subcarrier indication information to transmit uplink data.

For example, if the subcarrier indication information is priority information, when determining the subcarrier, the subcarrier with high priority can be selected as the uplink subcarrier for the mobile terminal to upload data; for another example, if the subcarrier indication information is the value of the carrier load condition , when determining the subcarrier, select the subcarrier with the smallest load as the uplink subcarrier for the mobile terminal to upload data; for another example, if the subcarrier indication information is the value of the random access collision probability, when determining the subcarrier, select the random access subcarrier The subcarriers with low access conflict probability are used as the uplink subcarriers for the mobile terminal to upload data.

In this embodiment, the uplink channel on which the mobile terminal transmits uplink data may be a random access channel (Radom Access Channel, RACH), an enhanced random access channel (Common E-DCH, Common EnhancedDedicated Channel), physical random access channel Channel (Physical Random Access Channel, PRACH), Dedicated Physical Control Channel (Dedicated Physical Control Channel, DPCCH), Dedicated Physical Data Channel (Dedicated Physical Data Channel, DPDCH), Enhanced Uplink Dedicated Channel Dedicated Physical Control Channel (Enhanced uplink DCH Dedicated Physical Control Channel, E-DPCCH), enhanced uplink dedicated channel dedicated physical data channel (E-DCH Dedicated Physical Data Channel, E-DPDCH) and uplink dedicated physical control channel (Dedicated Physical Control Channel) for high-speed downlink shared channel At least one of Channeluplink for HS-DSCH, HS-DPCCH).

For example, when the mobile terminal has no uplink transmission resources in the idle state or the cell forward access channel (CELL-FACH) state and needs to transmit uplink data, it can determine a random access channel or an enhanced random access channel to access the cell , and after the access channel is determined, an uplink carrier is determined to transmit uplink data on the uplink carrier. In practical applications, the uplink carrier for uploading data may also be determined first, and then the random access channel for uplink data transmission is determined.

Those skilled in the art can understand that which of the above-mentioned uplink channels can be pre-set on the mobile terminal to use the uplink subcarriers in the uplink carrier configuration information issued by the network control node for uplink data transmission, or the network control node can also be the mobile terminal An uplink channel for sending uplink data may be sent by selecting an uplink subcarrier in the uplink carrier configuration information.

Those skilled in the art can understand that the mobile terminal can determine subcarriers by random selection besides the subcarrier indication information. At this time, the subcarrier configuration information issued by the network control node does not need to carry Carrier indication information.

In this embodiment, when a mobile terminal accesses a cell through a random access channel or an enhanced random access channel, when the network control node issues the random access channel or the enhanced random access channel, it may also The channel or the enhanced random access channel allocates the corresponding uplink subcarrier, and sends the uplink subcarrier in the configuration information together with the random access channel or the enhanced random access channel to the mobile terminal. The following will be described with specific examples. FIG. 3 is a schematic flowchart of a wireless communication method provided in Embodiment 3 of the present application.

Step 303: When the network control node sends the random access channel to the mobile terminal, it sends the uplink subcarrier corresponding to the random access channel, so that when the mobile terminal accesses the cell based on the random access channel, the uplink subcarrier corresponding to the random access channel Uplink data is sent on the carrier.

Those skilled in the art can understand that a random access channel (Radom Access Channel, RACH), also called a common channel, is a channel issued by a network control node for a mobile terminal to randomly access a cell. channel access to the cell.

Those skilled in the art can understand that when the network control node allocates more than one corresponding uplink subcarrier to each random access channel, the mobile terminal can randomly select one uplink subcarrier from the multiple uplink subcarriers.

In this embodiment, in the above step 302, subcarrier indication information may also be assigned to the uplink subcarriers of each random access channel, and the subcarrier indication information is used to indicate the state of the uplink subcarrier corresponding to the random access channel Correspondingly, when sending the random access channel to the mobile terminal in the above step 303, send the uplink subcarrier and subcarrier indication information corresponding to the random access channel. In this way, the mobile terminal can determine the random access channel to access the cell based on the subcarrier indication information, and send uplink data on the uplink subcarrier corresponding to the determined random access channel to access the cell. Wherein, the subcarrier indication information is a value indicating the load status of the uplink subcarrier, or a value indicating the probability of random access collision, or information indicating the priority of the uplink subcarrier.

FIG. 4 is a schematic flowchart of a wireless communication method provided in Embodiment 4 of the present application. Different from the embodiment shown in FIG. 3 above, in this embodiment, the network control node can also allocate corresponding uplink subcarriers for the enhanced random access channel, so that the mobile terminal can Subcarriers transmit uplink data.

Step 403: When the network control node sends the enhanced random access channel to the mobile terminal, it sends the uplink subcarrier corresponding to the enhanced random access channel, so that when the mobile terminal accesses the cell based on the enhanced random access channel, the enhanced random access channel The uplink data is sent on the uplink subcarrier corresponding to the random access channel.

Those skilled in the art can understand that when the network control node allocates corresponding uplink subcarrier lists for all enhanced random access channels, the terminal can randomly determine an uplink subcarrier from multiple uplink subcarriers. The terminal may first determine the enhanced random access channel or first determine the uplink subcarrier.

In this embodiment, the above step 402 may also assign subcarrier indication information to the uplink subcarriers of each enhanced random access channel, and the subcarrier indication information is used to indicate the uplink subcarriers corresponding to the enhanced random access channel Correspondingly, step 403 may specifically send the uplink subcarrier and subcarrier indication information corresponding to the enhanced random access channel when sending the random access channel to the mobile terminal. In this way, the mobile terminal can determine the enhanced random access channel of the access cell based on the subcarrier indication information, and send uplink data on the uplink subcarrier corresponding to the determined enhanced random access channel of the access cell. Wherein, the subcarrier indication information is a value indicating the load of uplink subcarriers, or a value indicating the probability of random access collision, or priority indication information.

For example, the mobile terminal supports the capability of asymmetric uplink and downlink carrier bandwidths, and if there is a cell with asymmetric uplink and downlink carrier bandwidth in an adjacent cell, the mobile terminal may preferentially choose to reselect to the adjacent cell. For example, if the mobile terminal supports high-bandwidth downlink reception, and there is a downlink high-bandwidth cell among adjacent cells, the mobile terminal preferably reselects to the adjacent cell that supports high-bandwidth.

Those skilled in the art can understand that for a mobile terminal in idle state or CELL_FACH state, during the access process of the mobile terminal after determining an uplink carrier, the network control node can also instruct the mobile terminal to change the uplink subcarrier, specifically through Physical layer signaling or higher layer signaling indicates or allocates an uplink subcarrier for the terminal.
