Description

A kind of uplink joint receiving method and base station

technical field

The present invention relates to wireless communication technology, in particular to an uplink joint receiving method and a base station.

Background technique

Through the interaction of scheduling information and received signals among multiple cells, the uplink joint reception technology can realize the simultaneous joint reception of uplink signals of a single user by multiple cell antennas (users jointly received by multiple cells are usually referred to as cooperative users). Uplink joint reception for edge users is equivalent to improving uplink coverage.

The existing uplink joint technology can only be applied between different cells of the same base station. When applied across base stations, since the interaction and cooperation information needs to be transmitted through a Packet Transport Network (PTN, Packet Transport Network), the cross-base station transmission bandwidth and transmission delay cannot meet the requirements of the base station's uplink processing timing. At present, if the uplink joint reception technology needs to be implemented across base stations, it is necessary to introduce high-speed switching equipment between base stations. However, the introduction of cross-base station signaling switching equipment will bring higher costs.

Detailed ways

The inventor found that in the existing Long Term Evolution (LTE, Long Term Evolution) network, there has been a problem that the uplink signaling of the IMS-based voice service (VoLTE, Voice over LTE) service cannot be successfully sent in the weak field, resulting in weak The success rate of field VoLTE call origination is low; or the weak field VoLTE service has low uplink transmission efficiency, resulting in packet loss, resulting in VoLTE calls swallowing words and single calls. Weak fields need to enhance uplink coverage and improve the transmission efficiency of VoLTE signaling and service data packets, and most of the weak fields with uplink coverage exist at the cell boundaries of different base stations.

Step 3. The serving cell will report the uplink channel configuration of the cooperative user (mainly the transmission period and transmission position of the Sounding Reference Signal (SRS, Sounding Reference Signal)) and the physical resource block (PRB, Physical Resource Block) of the uplink scheduling to report the measurement report. information to the cooperative cell;

Step 4, the coordinated cell performs channel measurement on the coordinated user according to the SRS configuration;

The embodiment of the present invention also provides an uplink joint receiving method. FIG. 4 is a schematic flowchart of an uplink joint receiving method according to Embodiment 2 of the present invention; as shown in FIG. 4 , the method includes:

Step 201: After establishing a bearer with a terminal, or when the base station performs the first uplink/downlink scheduling on the terminal based on the bearer, the base station sends an A2 measurement control instruction to the terminal, and the A2 measurement control instruction corresponds to The measurement control condition is that the RSRP of the terminal in the serving cell is lower than the first threshold;

Step 202: When the terminal reports an A2 measurement report to the base station based on the received A2 measurement control command, the base station sends a CoMP A3 measurement control command to the terminal, and the measurement control command corresponding to the CoMP A3 measurement control command The condition is that the difference between the RSRP of the co-frequency adjacent cell and the RSRP of the serving cell is within the second threshold;

Step 204: The base station performs bearer determination based on the uplink data scheduling request of the terminal, and determines whether the uplink data scheduling request belongs to bearer i (bearer i is a bearer that needs to be enhanced for uplink).

Step 205: when the base station determines that the uplink data scheduling request belongs to bearer i, it sends the coordination information of the terminal that reports the measurement report to the coordinated cell; wherein the coordination information includes uplink channel configuration information (wherein the uplink The channel configuration information is mainly SRS transmission cycle and transmission position) and/or PRB information of uplink scheduling.

Step 206: The base station to which the cooperative cell belongs performs channel measurement on the cooperative user (that is, the terminal) according to the cooperation information (for example, the SRS transmission period and the transmission position included in the uplink channel configuration information); the base station to which the cooperative cell belongs, according to the channel measurement result, On the same PRB of the cooperating user that the serving cell schedules, the uplink received signal of the cooperating user (ie the terminal) is demodulated, and the demodulated soft information is sent to the terminal, and the base station performs soft information combination.

Embodiment 3

Based on the first embodiment, this embodiment further describes in detail a method for determining whether the bearer where the current data call is located belongs to a bearer that needs to be enhanced for uplink. Specifically, in response to the requirement for improving the uplink transmission efficiency of the weak coverage of VoLTE services, the bearer that needs to be enhanced in uplink coverage is the QoS Class Identifier (QCI, QoS ClassIdentifier) 1 bearer for transmitting VoLTE service packets. The base station to which the serving cell belongs may start the solution of Embodiment 1 of the present invention when the QCI 1 bearer is established. For a terminal that has established a QCI 1 bearer, the base station may determine the bearer to which the uplink scheduling belongs according to the number of transmitted bits when the terminal applies for uplink scheduling. For example, when the number of transmitted bits applied by the terminal for uplink scheduling is about 562 bits (the number of bits is within the pre-configured first range), the base station may determine that the uplink scheduling applied for this time belongs to QCI 1 Bearing, cross-base station uplink joint reception can be performed; correspondingly, when the number of transmitted bits applied by the terminal for uplink scheduling is much larger than 562 bits (the number of bits is not within the first range or the number of bits is within the pre-configured second range) , the base station can determine that the uplink scheduling applied for this time does not belong to the QCI 1 bearer, or that the uplink scheduling applied this time belongs to other bearers except the QCI 1 bearer, and therefore does not perform cross-base station uplink joint reception.

Embodiment 4

Based on the first embodiment, this embodiment further describes in detail another way of judging whether the bearer where the current data call is located belongs to the bearer that needs to be enhanced for uplink. Specifically, in response to the requirement of improving the uplink transmission efficiency of the weak coverage of the VoLTE service, the bearer that needs to be enhanced in the uplink coverage is the QCI 1 bearer that transmits the VoLTE service package. The base station to which the serving cell belongs may start the solution of Embodiment 1 of the present invention when the QCI 1 bearer is established. For a terminal that has established a QCI 1 bearer, the base station can determine the bearer to which the uplink scheduling belongs according to the logical channel group number when the terminal applies for uplink scheduling. For example: when the terminal applies for the logical channel group number for uplink scheduling (of course, it may also be other parameters, referring to the specific logical channel group to which the QCI 1 voice packet is mapped) and the logical channel group number used for transmitting the QCI 1 data When the matching is consistent, the base station can determine that the data applied for scheduling this time belongs to the QCI 1 bearer, and can perform cross-base station uplink joint reception; When the group ID matches are inconsistent, the base station can determine that the data applied for scheduling this time does not belong to the QCI 1 bearer, and therefore does not perform cross-base station uplink joint reception this time.
