- the design goals of the NR/5G system include large-bandwidth communications in high frequency bands (for example, frequency bands above 6 GHz). When the operating frequency becomes higher, the path loss in the transmission process will increase, thereby affecting the coverage capability of the high-frequency system. In order to be able to effectively ensure the coverage of the high-frequency NR system, an effective technical solution is based on a large-scale antenna array, using multi-beam technology to improve coverage.
- a cell uses a wider beam (beam) to cover the entire cell. Therefore, at each moment, the UE within the coverage of the cell has the opportunity to obtain the transmission resources allocated by the system.
- the NR/5G multi-beam (Multi-beam) system uses different beams to cover the entire cell, that is, each beam covers a small area, and the effect of multiple beams covering the entire cell is achieved through sweeping in time.
- different beams are identified through different signals carried on them:
- SS block Synchronizing Signal block
- CSI-RS channel state information reference signal
- the Physical Downlink Control Channel (PDCCH) and PDSCH can be transmitted through different downlink transmission beams.
- PDCH Physical Downlink Control Channel
- a multi-beam system the Physical Downlink Control Channel (PDCCH) and PDSCH can be transmitted through different downlink transmission beams.
- an omnidirectional antenna or an antenna close to omnidirectional
- the corresponding downlink receiving beam needs to be used to receive the signal sent by the corresponding downlink sending beam.
- corresponding beam indication information is needed to assist the UE in determining the transmission beam related information on the network side, or the corresponding reception beam related information on the UE side.
- the UE detects only one NR-PDCCH, and a DCI detected by the control channel PDCCH indicates related indication information of data transmitted simultaneously on multiple TRPs/panel/beams. For example, the transmission on different TRP/panel/beam can be implicitly indicated through different Quasi co-location (QCL) information.
- QCL Quasi co-location
- the UE receives different NR-PDCCHs from different TRPs/panel/beams, and the DCI detected on the PDCCH of each control channel indicates a corresponding data transmission related indication information.
- the UE only needs to detect one NR-PDCCH, so the control channel detection complexity may be lower than the second solution.
- the first solution requires rapid information exchange between different panels/TRP/beam.
- the UE needs to detect multiple NR-PDCCHs on the same carrier at the same time.
- the complexity may increase, but the flexibility and robustness may be improved.
- the possible application scenarios of the second solution are at least the following:
- TRPs belong to the same cell, and the backhaul between TRPs is ideal (that is, information can be exchanged quickly and dynamically);
- TRPs belong to the same cell, and the connection (backhaul) between TRPs is non-ideal (that is, TRPs cannot exchange information quickly, and can only exchange data relatively slowly);
- TRPs belong to different cells, and the backhaul between TRPs is ideal;
- TRPs belong to different cells, and the backhaul between TRPs is not ideal.
- control resource set corresponds to a higher layer configuration index (a higher layer signalling index).
- One high layer configuration index can correspond to multiple CORESETs.
- Each high layer configuration index can be considered to correspond to 1 TRP, that is, to 1 higher layer configuration.
- One or more CORESET corresponding to the index corresponds to the same TRP.
- CORESET 0, 1, 2 corresponds to the index 0 of the high-level configuration
- CORESET 3 and 4 correspond to the index 1 of the high-level configuration
- the PDCCHs corresponding to CORESET 0, 1, and 2 are all sent from TRP 0, and the PDCCHs corresponding to CORESET 3, 4 are all sent from TRP 1.
- HARQ-ACK information can also be called ACK/NACK.
- one or more HARQ-ACK bits form a HARQ-ACK codebook.
- HARQ-ACK codebooks there are two types of HARQ-ACK codebooks: semi-static HARQ-ACK codebook and dynamic HARQ-ACK codebook.

- the terminal device can determine the semi-static HARQ-ACK codebook according to the candidate transmission occasions, and the semi-static HARQ-ACK codebook can be used to indicate the feedback information corresponding to these candidate transmission occasions, that is, the semi-static HARQ-ACK codebook.

- the terminal device may determine the type of the HARQ-ACK codebook as a semi-static HARQ-ACK codebook according to the configuration of the network device.
- the candidate transmission opportunity corresponds to one or more serving cells. It can also be said that the high-level configuration index corresponding to the candidate transmission opportunity corresponds to one or more serving cells.
- multiple TRPs belong to different cells, so similarly, multiple high-level configured indexes can also correspond to different cells.
- the candidate transmission opportunity corresponds to the index 0 configured by the high layer and the index 1 configured by the high layer, while the index 0 configured by the high layer corresponds to serving cell 0 and serving cell 1, and the index 1 configured by the high layer corresponds to serving cell 2 and serving cell 3.
- the transmission timing corresponding to a high-level configured index on a serving cell can be classified as a transmission timing set, then the candidate transmission timing may be composed of multiple transmission timing sets.
- Different transmission timing sets correspond to different high-layer configuration indexes, or different transmission timing sets correspond to different serving cells, or different transmission timing sets correspond to different high-layer configuration indexes and different serving cells. If all candidate transmission opportunities are classified into a transmission opportunity set, then the candidate transmission opportunity is composed of a transmission opportunity set.
- the transmission timing set in the embodiment of the present application may also be divided based on other methods, for example, the candidate transmission timing set is randomly divided into at least one transmission timing set.
- the terminal device may determine the semi-static HARQ-ACK codebook based on the number of transmission occasions in each transmission occasion set in at least one transmission occasion set included in the candidate transmission occasions. For example, the number of transmission opportunities in each transmission opportunity set can be determined by Indicates that, c represents the index of the serving cell, which can start from 0, and t represents the index of the high-level configuration, or it can start from 0, and the terminal equipment can be based on all To determine the semi-static HARQ-ACK codebook.

As for the order of the feedback information corresponding to transmission timing 1 and the feedback information corresponding to transmission timing 2, the terminal may autonomously determine the sequence, or may also be determined based on other rules.
