Description

Configuration method, base station and terminal for uplink SRS antenna transmission
Technical Field
The invention relates to the technical field of wireless communication, in particular to a configuration method, a base station and a terminal for uplink SRS antenna transmission.
Background
Sounding Reference Signal (SRS) is transmitted by a single antenna, which limits a Multi-user Multiple-Input Multiple-Output (MU-MIMO) technique in 3D Multiple-Input Multiple-Output (3D-MIMO), and each user can only support a single stream. When supporting downlink single-user double-flow, the base station needs information of 2 antennas of the terminal. A terminal sends an SRS by a single antenna, one channel information is lost, when the MU-MIMO technology is not adopted, a base station can assume that the other channel is orthogonal, and a second stream is blindly created; when the MU-MIMO technology is adopted, the above method may cause serious inter-User interference, so that Multi-User (MU) and single-User dual streams cannot be simultaneously realized.
Based on the problems, the existing uplink SRS antenna transmission mode is usually adopted to solve, and according to channel reciprocity, the base station can obtain the exact information of two channels, so that the base station does not need to blindly make a second stream in a non-MU-MIMO environment, and can be accurately constructed, and the downlink rate can be obviously improved in a cell. For MU-MIMO, due to the exact information of two channels, MU and single user double stream can be realized simultaneously.
However, when the above method is adopted, for a terminal working in uplink carrier aggregation, two antennas respectively bear different carriers according to the current hardware implementation mechanism, and in this case, if the base station configures an uplink SRS antenna for the terminal for transmission, the terminal cannot work normally. In the future, if there is uplink carrier aggregation in frequency bands with more carriers, the uplink carrier aggregation is likely to be carried on different antennas for transmission, and thus normal operation of the terminal is affected. Therefore, this problem needs to be treated carefully.

Detailed Description
The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are some, not all, embodiments of the present invention. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.
The embodiment of the invention provides a configuration method for uplink SRS antenna wire sending, which is applied to a base station, and as shown in figure 1, the method comprises the following steps:
step 101, detecting the condition of the uplink SRS of the scheduling terminal in the uplink carrier aggregation state under the current uplink carrier aggregation capability supported by the base station.
According to the configuration method for the uplink SRS antenna sending, disclosed by the embodiment of the invention, the base station detects the condition of the uplink SRS in the uplink carrier aggregation state of the scheduling terminal under the condition of currently supporting the uplink carrier aggregation capability. Wherein the detection process can be performed in two detection modes. The first method requires the base station to detect according to the current strategy and configuration and the current reported capability information of the terminal, and the reported capability information of the terminal is the common capability information in the existing protocol; the second method is to detect whether the base station acquires the capability indication information which is transmitted by the terminal and has the uplink SRS transmission capability for uplink carrier aggregation under the condition that the base station supports the uplink carrier aggregation capability. The two detection methods are described below.
For the first detection mode
The process of detecting the condition of the uplink SRS in the uplink carrier aggregation state of the scheduling terminal under the current capability of supporting uplink carrier aggregation of the base station, as shown in fig. 2, includes:
step 201, detecting the strategy configuration information of the base station and the capability information reported by the terminal.
Step 202, according to the policy configuration information and the capability information, determining whether a condition of an uplink SRS in an uplink carrier aggregation state of the scheduling terminal is detected when the base station currently supports the uplink carrier aggregation capability.
In the detection process, firstly, the strategy configuration information of the base station and the capability information reported by the terminal are detected. The policy configuration information of the base station comprises: first configuration information on whether the base station supports uplink carrier aggregation and second configuration information on whether the base station supports uplink SRS scheduling for the uplink carrier aggregation; the capability information reported by the terminal comprises: the terminal includes first capability information regarding whether the terminal supports uplink SRS antenna transmission and second capability information regarding whether the terminal supports uplink carrier aggregation.
When detecting the policy configuration information of the base station, it is necessary to detect whether the base station supports the first configuration information of uplink carrier aggregation, and also to detect whether the base station supports the second configuration information of uplink SRS scheduling for uplink carrier aggregation.
The process of detecting the first configuration information is as follows: and detecting whether the uplink carrier aggregation between the frequency bands is configured, and if the base station supports the uplink carrier aggregation between the frequency bands, detecting second configuration information. The process of detecting the second configuration information is as follows: and judging whether SRS configuration is started for a matched terminal supporting uplink carrier aggregation capability according to the configuration file, wherein the uplink carrier aggregation comprises intra-band carrier aggregation and inter-band carrier aggregation, and the inter-band carrier aggregation currently refers to that the terminal transmits different carriers by branch antennas.
When detecting the capability information reported by the terminal, it is necessary to detect whether the terminal supports the first capability information sent by the uplink SRS antenna, and also to detect whether the terminal supports the second capability information of uplink carrier aggregation. The capability information reported by the current terminal is common capability information in the existing protocol.
And after the detection is finished, executing a process of judging whether the condition of the uplink SRS of the terminal in the uplink carrier aggregation state is detected under the condition that the base station currently supports the uplink carrier aggregation capability according to the strategy configuration information and the capability information according to the detection result.
The step of judging whether the condition of the uplink SRS in the uplink carrier aggregation state of the scheduling terminal under the condition that the base station currently supports the uplink carrier aggregation capability is detected or not according to the strategy configuration information and the capability information comprises the following steps:
when the base station is determined to support uplink carrier aggregation according to the strategy configuration information, uplink SRS operation aiming at the current uplink carrier aggregation capability supported by the base station can be supported, the terminal is determined to support uplink SRS antenna polling according to the capability information, uplink carrier aggregation can be supported, and the uplink carrier aggregation capability of the base station is not matched with the uplink carrier aggregation capability of the terminal, the condition that the uplink SRS of the terminal in an uplink carrier aggregation state is scheduled under the current uplink carrier aggregation capability supported by the base station is determined and detected.
If the base station is determined to support uplink carrier aggregation after the first configuration information is detected, it is determined that uplink SRS operation can be supported aiming at the uplink carrier aggregation capability currently supported by the base station after the second configuration information is detected, it is determined that the terminal supports uplink SRS antenna transmission after the first configuration information is detected, it is determined that the terminal supports uplink carrier aggregation after the second configuration information is detected, and at this time, it is also required to detect whether the uplink carrier aggregation capability of the base station is matched with the uplink carrier aggregation capability of the terminal. And under the conditions that the base station is determined to support uplink carrier aggregation, uplink SRS operation aiming at the current uplink carrier aggregation capability supported by the base station can be supported, the terminal is determined to support uplink SRS antenna transmission and can support uplink carrier aggregation, and the uplink carrier aggregation capability of the base station is not matched with the uplink carrier aggregation capability of the terminal, the condition that the uplink SRS of the terminal in an uplink carrier aggregation state is scheduled under the condition that the base station is detected to support the current uplink carrier aggregation capability is determined.
In the embodiment of the invention, the base station detects the strategy configuration information of the base station and the capability information reported by the terminal, judges whether the condition of the uplink SRS in the uplink carrier aggregation state of the terminal is scheduled under the condition that the base station currently supports the uplink carrier aggregation capability is detected according to the result, and executes the subsequent SRS antenna transmitting mechanism under the condition that the condition is detected, so that the double flow of multiple users and a single user can be simultaneously realized on the basis of ensuring the normal work of the terminal.
Wherein, according to the policy configuration information and the capability information, determining whether to detect that the uplink SRS is scheduled in the uplink carrier aggregation state of the terminal when the base station currently supports the uplink carrier aggregation capability further includes:
when at least one condition is determined to be satisfied according to the policy configuration information and the capability information, determining that the condition of scheduling the uplink SRS of the terminal in an uplink carrier aggregation state is not detected when the base station currently supports the uplink carrier aggregation capability: the base station does not support uplink carrier aggregation and does not support uplink SRS scheduling; the base station supports uplink carrier aggregation but does not support uplink SRS scheduling; and the uplink carrier aggregation capability of the base station is matched with the uplink carrier aggregation capability of the terminal and supports uplink SRS scheduling.
When the base station is detected not to support uplink carrier aggregation and uplink SRS scheduling, determining that the uplink SRS condition of the terminal in an uplink carrier aggregation state is scheduled under the condition that the base station does not support uplink carrier aggregation currently; the method can also determine the condition of scheduling the uplink SRS of the terminal in the uplink carrier aggregation state under the condition that the current uplink carrier aggregation supporting capability of the base station is not detected when the base station is detected to support uplink carrier aggregation but not support uplink SRS scheduling; or when it is detected that the uplink carrier aggregation capability of the base station matches the uplink carrier aggregation capability of the terminal and the base station supports uplink SRS scheduling, determining that the condition for scheduling the uplink SRS in the uplink carrier aggregation state of the terminal is not detected when the base station currently supports the uplink carrier aggregation capability.
That is, when any of the three cases occurs, it may be determined that the condition for scheduling the uplink SRS in the uplink carrier aggregation state of the terminal is not detected when the base station currently supports the uplink carrier aggregation capability.
By limiting the three conditions that the condition is determined not to be detected, the base station can stop the detection process when any one condition occurs, and the condition is directly determined not to be detected, so that the detection flow of the base station is simplified.
For the second detection mode
Detecting the condition of the uplink SRS in the uplink carrier aggregation state of the scheduling terminal under the current capability of supporting uplink carrier aggregation of the base station, as shown in fig. 3, includes:
step 301, detecting whether capability indication information which is sent by the terminal and has uplink SRS alternate sending capability for uplink carrier aggregation is obtained or not when the base station currently supports the uplink carrier aggregation capability.
Step 302, when the capability indication information is detected, determining that the condition of the uplink SRS of the scheduling terminal in the uplink carrier aggregation state is detected when the base station currently supports the uplink carrier aggregation capability.
For the second detection method, the terminal may directly transmit the capability indication information with the uplink SRS scheduling capability for uplink carrier aggregation, and for the base station, it may detect whether the capability indication information with the uplink SRS scheduling capability for uplink carrier aggregation is obtained, where the capability indication information is sent by the terminal and has the uplink SRS scheduling capability for uplink carrier aggregation, and if the base station obtains the capability indication information with the uplink SRS scheduling capability for uplink carrier aggregation, which is sent by the terminal, the base station may determine that the condition for scheduling the uplink SRS in the uplink carrier aggregation state of the terminal is detected, where the base station currently supports the uplink carrier aggregation capability.
Compared with the first detection method, in this way, the terminal directly sends the capability indication information, which can simplify the detection process of the base station. The difference between the capability indication information sent by the terminal and the common capability information in the existing protocol is explained by explaining a process of detecting whether the capability indication information with the uplink SRS round-robin transmission capability for uplink carrier aggregation is obtained from the terminal under the current uplink carrier aggregation supporting capability of the base station.
The method for detecting whether the capability indication information which is sent by the terminal and has the uplink SRS polling capability aiming at the uplink carrier aggregation is acquired under the current capability of supporting the uplink carrier aggregation of the base station comprises the following steps:
detecting capability information supporting uplink carrier aggregation of a preset frequency band, which is sent by a terminal, wherein a preset field is added in the capability information; when the preset field is a first preset value, acquiring capability indication information which is sent by a terminal and has uplink SRS transmitting capability aiming at uplink carrier aggregation; and when the preset field is a second preset value, acquiring capability indication information which is sent by the terminal and does not have the uplink SRS transmitting capability aiming at the uplink carrier aggregation.
When the detection process is executed, the preset field added in the capability information supporting uplink carrier aggregation of the preset frequency band and sent by the detection terminal is detected, if the preset field added in the capability information sent by the terminal is a first preset value, it can be determined that the base station obtains the capability indication information which is sent by the terminal and has the uplink SRS polling capability for uplink carrier aggregation, and if the preset field added in the capability information sent by the terminal is a second preset value, it can be determined that the base station obtains the capability indication information which is sent by the terminal and does not have the uplink SRS polling capability for uplink carrier aggregation.
The capability indication information sent by the terminal includes two types, which can be distinguished according to preset values in preset fields, if the preset fields are first preset values, the capability indication information is determined to be capability indication information with uplink SRS transmission capability for uplink carrier aggregation, and if the preset fields are second preset values, the capability indication information is determined to be capability indication information without uplink SRS transmission capability for uplink carrier aggregation.
The above is an introduction to two detection procedures, wherein when detecting a condition that the base station currently supports uplink carrier aggregation capability and schedules an uplink SRS in an uplink carrier aggregation state for the terminal, as shown in fig. 1, on the basis of completing step 101, step 102 is executed.
And 102, if the condition is detected, configuring uplink SRS antenna transmission for the terminal when the terminal is in an uplink carrier aggregation state.
When the condition that the base station currently supports the uplink carrier aggregation capability and schedules the uplink SRS in the uplink carrier aggregation state of the terminal is detected, and the base station executes the process of configuring the uplink SRS antenna transmission for the terminal under the condition that the terminal is determined to be in the uplink carrier aggregation state.
By configuring uplink SRS antenna transmission for the terminal in the state, the normal operation of the terminal can be ensured through the SRS antenna transmission mechanism aiming at the terminal working in the uplink carrier aggregation state, and the double current of multiple users and a single user can be realized simultaneously.
