Description

A method and device used in a node for wireless communication

technical field

The present application relates to a transmission method and device in a wireless communication system, especially a wireless signal transmission method and device in a wireless communication system supporting a cellular network.

Background technique

Multi-antenna technology is a key technology in 3GPP (3rd Generation Partner Project, third generation partnership project) LTE (Long-term Evolution, long-term evolution) system and NR (New Radio, new radio) system. Additional spatial degrees of freedom are obtained by configuring multiple antennas at a communication node, such as a base station or a UE (User Equipment, User Equipment). Multiple antennas use beamforming to form beams pointing in a specific direction to improve communication quality. The beams formed by multi-antenna beamforming are generally narrow, and the beams of the communicating parties need to be aligned for effective communication. When the transmission/reception beams are out of synchronization due to reasons such as UE movement, the communication quality will be greatly reduced or even communication will be impossible. In NRR (release) 15 and R16, beam management is used for beam selection, update and indication between communication parties, so as to achieve performance gain brought by multiple antennas. When multiple antennas belong to multiple TRPs (Transmitter Receiver Points)/panels (antenna panels), additional diversity gain can be obtained by utilizing the spatial differences between different TRPs/panels. In NR R(release)16, multi-TRP based transmission is introduced to enhance the transmission quality of the downlink data channel.

Contents of the invention

In NR R15 and R16, the control channel and data channel adopt different beam management/indication mechanisms, and the uplink and downlink also adopt different beam management/indication mechanisms. However, in many cases, the control channel and the data channel can use the same beam, and there is channel reciprocity between the uplink and downlink channels in many application scenarios, and the same beam can be used. Utilizing this feature can greatly reduce system complexity, signaling overhead and delay. In the 3GPP RAN (Radio Access Network, radio access network) 1#103e meeting, the technology of using DCI (Downlink control information, downlink control information) to simultaneously update the beams of the control channel and the data channel has been adopted. The updated beam, also called an active beam, can be used for a part of reference signals in addition to the control channel and the data channel.

The applicant found through research that when there are two active beams in the system at the same time, the relationship between the reference signal and the active beam is a problem that needs to be solved. Aiming at the above problems, the present application discloses a solution. It should be noted that although the above description uses the cellular network and reference signal as an example, this application is also applicable to other scenarios such as sidelink (Sidelink) transmission and other physical layer channels/signals, and obtains similar technical effect. In addition, adopting a unified solution for different scenarios (including but not limited to cellular network, secondary link, reference signal and other physical layer channels/signals) also helps to reduce hardware complexity and cost. In the case of no conflict, the embodiments and the features of the embodiments in the first node of the present application can be applied to the second node, and vice versa.
