Embodiment 1

[0077] When the RRC configuration information includes configuration information of the TCI state information corresponding to the MAC CE, the MAC CE carries the TCI state information; or

[0078]When the RRC configuration information does not include the configuration information of the TCI state information corresponding to the MAC CE, the MAC CE carries or does not carry the TCI state information;

[0079] That is, when the received RRC configuration information includes the configuration information of the TCI state information corresponding to the MAC CE, it indicates that the MAC CE received by the terminal will carry the TCI state information;

[0080] When the received RRC configuration information does not include the configuration information of the TCI status information corresponding to the MAC CE, it indicates that the MAC CE received by the terminal may or may not carry the TCI status information. information.

[0081] In this case, when the MAC CE carries the T...

Embodiment 2

[0090] One way of this embodiment is:

[0091] The RRC configuration information may include indication information, where the indication information is used to indicate whether the first MAC CE used to activate / deactivate the SP SRS resource set carries the TCI status information;

[0092] When the indication information indicates that the first MAC CE carries the TCI state information, the first MAC CE carries the TCI state information;

[0093] When the indication information indicates that the first MAC CE does not carry the TCI state information, the first MAC CE carries or does not carry the TCI state information;

[0094] The step of judging whether to ignore the TCI state information carried by the MAC CE according to the RRC configuration information when the MAC CE carries the TCI state information includes:

[0095] When the indication information indicates that the first MAC CE carries the TCI status information, and the received first MAC CE carries the TCI statu...

Embodiment 3

[0109] The RRC configuration information includes bitmap indication information, where the bitmap indication information is used to indicate whether each resource in the semi-static reference signal resource set in the MAC CE is carried in the MAC CE.

[0110] Each bit in the bitmap indication information is respectively used to indicate whether each resource in the semi-static reference signal resource set is carried in the MAC CE. For example, when the bit position is "1", it indicates that the MAC CE carries the resource corresponding to the bit, and when the bit position is "0", it indicates that the MAC CE does not carry the resource corresponding to the bit.

[0111] That is, in the RRC signaling, whether each resource in the semi-static reference signal resource set in the MAC CE is carried in the MAC CE is clarified in the form of a bitmap, so as to hide the It is explicitly stated whether the TCI status information of each resource in the semi-static reference signal ...

Abstract

The embodiment of the invention provides a TCI state indication method, a terminal and network side equipment. The TCI state indication method applied to the terminal comprises: receiving RRC configuration information, the RRC configuration information indicating whether TCI state information is carried in an activation / deactivation MAC CE of a semi-static reference signal resource set for beam management, the TCI state information being used for indicating a QCL spatial relationship of the semi-static reference signal resource set; enabling the terminal to receive the MAC CE; and when the MACCE carries the TCI state information, judging whether the TCI state information carried by the MAC CE is ignored or not according to the RRC configuration information. According to the embodiment ofthe invention, the terminal determines whether the activation / deactivation MAC CE carries the TCI state information according to the RRC configuration information, thereby determining whether the TCIstate information carried by the MAC CE is ignored, and enabling the MAC CE to be processed accurately.

Description

technical field [0001] Embodiments of the present invention relate to the field of wireless communication technologies, and in particular, to a transmission configuration indicator (Transmission Configuration Indicator, TCI) state indication method, a terminal, and a network-side device. Background technique [0002] Here are some related terms for communication: [0003] 1. Quasi-collocation (QCL) [0004] Quasi-colocation means that for signals with the same channel characteristics between different channels, it can be assumed that these signals come from the same transmission source. The QCL configuration can include many different signal types, such as Channel State Information-Reference Signaling (CSI-RS) or Synchronous Signal Block (SSB) or Sounding Reference Signal (Sounding Reference Signal) , SRS). The network-side device can configure its corresponding QCL configuration for different beams. The network-side device can change the beam in which the terminal works...
