In order to facilitate understanding by those skilled in the art, the embodiments of the present disclosure enumerate multiple implementations to clearly describe the technical solutions of the embodiments of the present disclosure. Of course, those skilled in the art can understand that the multiple embodiments provided in the embodiments of the present disclosure can be executed alone or in combination with the methods of other embodiments in the embodiments of the present disclosure. They can also be executed alone or in combination. It is then executed together with some methods in other related technologies; the embodiments of the present disclosure do not limit this.

In order to better understand the technical solutions described in any embodiment of the present disclosure, first, the application scenarios in related technologies are described:

In one application scenario, in the high frequency band, as the integration of active antenna devices increases, modular active antenna arrays will be more inclined to be used. The antenna array of each TRP can be divided into several relatively independent antenna panels, so the shape and number of ports of the entire array can be flexibly adjusted according to deployment scenarios and business needs. Antenna panels or TRPs can also be connected by optical fibers for more flexible distributed deployment. In the millimeter wave band, as the wavelength decreases, the blocking effect caused by obstacles such as human bodies or vehicles will become more significant. In this case, from the perspective of ensuring the robustness of the link connection, cooperation between multiple TRPs or panels can also be used to transmit/receive from multiple beams from multiple angles, thereby reducing the impact caused by the blocking effect. Negative Effects.

In one scenario embodiment, based on the mapping relationship between sending signal flows to multiple TRPs or panels, the coordinated multipoint transmission technology can be divided into two types: coherent and non-coherent transmission. Among them, during coherent transmission, each data layer will be mapped to multiple TRPs or panels through weighted vectors. In non-coherent transmission, each data stream is only mapped to part of the TRP or panel. Coherent transmission has higher requirements for synchronization between transmission points and the transmission capacity of the backhaul link, and is therefore sensitive to many non-ideal factors in actual deployment conditions. Relatively speaking, non-coherent transmission is less affected by the above factors, so it is a key consideration for multi-point transmission technology.

In one scenario embodiment, the uplink Physical Uplink Shared Channel (PUSCH) transmission is transmitted in the TRP direction of multiple base stations, as shown in Figure 2, providing cooperative transmission in the TDM transmission mode, through the time domain Different transmission opportunities send the same transport block (TB, Transport Block) of PUSCH to different TRPs of the base station in a time-sharing manner. This method has relatively low requirements on terminal capabilities, does not require the ability to support simultaneous beam transmission, and has a large transmission delay.

In related technologies, it is hoped that simultaneous collaborative transmission in the TRP direction of multiple base stations can be achieved through multiple terminal panel panels to increase the reliability and throughput of transmission. At the same time, it can effectively reduce the transmission delay under multiple TRPs, but the terminal is required to have The ability to send multiple beams simultaneously.

As shown in Figure 3, this embodiment provides a method for indicating a redundant version RV, which is applied to access network equipment. The method includes:

In the scenario of single DCI control, it mainly refers to realizing coordinated transmission of different panels or TRP links through DCI control information transmitted on a physical downlink control channel (PDCCH, Physical Downlink Control Channel).

The third transmission method, that is, SDM-2: a single RV space division scheme, the same TB is transmitted by corresponding to different data layers in different panels/TRPs, and mapped on the same time-frequency resources;

The fourth transmission method, that is, SDM-3: multiple RV space division scheme, different RV versions of the same TB are sent in different panels/TRP corresponding to different data layers, and mapped to the same time-frequency resources Come up and realize it;

In the FDM scenario, the following transmission methods are included:

The fifth transmission method, that is, FDM-1: a frequency division scheme for a single RV, the same TB is implemented by sending the same data layer in different panels/TRPs and mapping it on non-overlapping frequency domain resources;

The sixth transmission method, that is, FDM-2: Frequency division scheme of multiple RVs. Different RV versions of the same TB are sent in different panels/TRPs corresponding to the same data layer and mapped to non-overlapping frequency domain resources. accomplish;

It can be understood that the single RV transmission method in the present disclosure can correspond to the third transmission method and the fifth transmission method; the multiple RV transmission method can correspond to the fourth transmission method and the sixth transmission method.
