Description
Technical Field
The present invention relates to the field of communications technologies, and in particular, to a resource allocation method and a network device.
Background
The central user rate of the 5G network is high, and the edge user experience still needs to be improved in order to provide a consistent user experience. Especially for high frequency bands, edge coverage is urgently needed to be enhanced. As shown in fig. 1, multi-TRP (Transmission and Reception Point, transceiver point, e.g., network device, where the network device may be a base station, etc.) provides services to edge users simultaneously with multiple TRPs, enhancing coverage of edge users while boosting rate.
In Multi-TRP transmission, a scheme (independent scheduling) that tends to support Multi-PDCCH (physical downlink control channel) transmission can reduce the dependency of cooperative transmission on backhaul.
In order to ensure demodulation performance of the resources with high partial priority (such as control resources, system information block SIB1, etc.), PDSCH (physical downlink shared channel) transmission needs to puncture (rate matching) the positions of the partial resources.
The higher layer signaling Rate Match Pattern (rate matching pattern) configures the user with a plurality of resource locations requiring rate matching.
There are two pattern types, one is bitmaps and one is Control Resource Set (control resource set) number.
Then, a corresponding pattern is selected in DCI (downlink control information) to perform rate matching.
When a plurality of TRPs are independently scheduled, the PDSCH1 of TRP1 can perform rate matching on the PDCCH1, but the TRP1 lacks the resource allocation information of the PDCCH2 and cannot perform rate matching on the PDCCH 2. Thus, PDCCH1 may be subjected to strong interference by PDSCH2, and PDCCH2 may be subjected to strong interference by PDSCH1, thereby affecting the demodulation performance of the control channel (with high priority, demodulation performance is desired to be guaranteed).
As shown in fig. 2, in the non-cooperative scenario, scheduling between cells is independent. There is also a problem in that the PDCCH of cell 1 is interfered with the PDSCH of cell 2. Also by UE self interference cancellation. But in a non-cooperative scenario, UE1 perceives interference sent by different base stations to different UEs, with less interference.
In the cooperative transmission scene, the two cooperative base stations have larger signal interference to the current UE, and have larger influence on the resource demodulation performance with high priority.
Thus, PDCCH1 may be subjected to strong interference of PDSCH2, and PDCCH2 may be subjected to strong interference of PDSCH1, thereby affecting control channel demodulation performance.

the TRP2 configures second rate matching pattern information for the terminal, the corresponding resource is the resource 21 occupied by the PDCCH2, and the PDSCH2 transmitting the TRP2 is performed by using the resource 22.
Through the method according to the above embodiment of the present invention, the terminal does not detect PDSCH1 and PDSCH2 on resources 31 and 32 and detects PDSCH1 and PDSCH2 on resources 33 according to the target rate matching pattern information;
wherein resource 31 is the same as resource 11, and resource 32 is the same as resource 21; this is because resources 31 and 32 are excluded when TRP1 and TRP2 are rate-matched, so that the terminal does not cause interference to PDCCH1 or PDCCH2 when detecting PDSCH1 and PDSCH2, thereby affecting control channel demodulation performance.
According to the embodiment of the invention, the configuration condition of the resource information of expected rate matching is interacted between the cooperative network equipment (such as the base stations), so that the interference of the cooperative base station data transmission on the current base station control channel transmission can be reduced, and the control channel demodulation performance is improved.
