Description

Method and equipment for indicating spatial relationship

Technical Field

The invention relates to the technical field of communication, in particular to a method and equipment for indicating a spatial relationship.

Background

Due to the introduction of beam forming, the terminal receives or transmits data through beams, that is, the terminal can only receive and transmit data in a certain specific spatial direction at the same time. To ensure communication between the terminal and the network, the terminal needs to know a beam direction for transmission or reception.

The terminal reception or transmission beam direction may be configured by the network, wherein the reception or transmission beam direction of each Carrier (CC) or each cell or each partial bandwidth or each network node is individually configured and activated.

Taking the carrier as an example, for each carrier, the network sends a signaling to notify the terminal of the beam direction used by the carrier for data transmission and reception. Therefore, when multiple carriers are subjected to carrier aggregation, the network needs to configure its beam direction for each carrier. This configuration results in a relatively large signaling overhead.

20. A terminal, comprising:

a first sending module, configured to send capability information, where the capability information is used to indicate whether the terminal supports simultaneous activation, deactivation, or update of multiple carriers, cells, partial bandwidths, and/or spatial relationships of sending or receiving of network nodes.

21. A terminal, comprising: a first transceiver and a first processor;

the first transceiver is further configured to transmit capability information, where the capability information is used to indicate whether the terminal supports simultaneous activation, deactivation or updating of multiple carriers, cells, partial bandwidths, and/or spatial relationships of transmission or reception of network nodes.

22. A network device, comprising:

a second sending module, configured to send first information, where the first information is used to indicate activation, deactivation, or update of a first spatial relationship; wherein the first spatial relationship represents a spatial relationship of a plurality of transmissions or receptions of a terminal;

a third receiving module, configured to receive capability information, where the capability information is used to indicate whether the terminal supports simultaneous activation, deactivation, or updating of multiple carriers, cells, partial bandwidths, and/or spatial relationships of transmission or reception of network nodes.

23. A network device, comprising: a second transceiver and a second processor;

the second transceiver is configured to transmit first information indicating activation, deactivation or update of a first spatial relationship; wherein the first spatial relationship represents a spatial relationship of a plurality of transmissions or receptions of a terminal;

the second transceiver is further configured to receive capability information, where the capability information is used to indicate whether the terminal supports simultaneous activation, deactivation, or updating of multiple carriers, cells, partial bandwidths, and/or spatial relationships of transmission or reception of network nodes.

24. A communication device, comprising: processor, memory and program stored on the memory and executable on the processor, which when executed by the processor implements the steps of the method of spatial relationship indication according to any of claims 1 to 19.

25. A computer-readable storage medium, characterized in that a computer program is stored thereon, which computer program, when being executed by a processor, carries out the steps of the method of spatial relationship indication according to any one of claims 1 to 19.
