Communication of state switching information
A method for information transmission performed by a based station includes: sending second indication information, wherein the second indication information is configured to indicate to switch a state of resource configuration information of a reference signal. An initial state of resource configuration information comprises: an available state and an unavailable state. The initial state is specified in a communication protocol; and the state of the resource configuration information is able to be switched from the unavailable state to the available state, or from the available state to the unavailable state.
1 . A method for information transmission, performed by a base station, the method comprising:
sending a downlink control information (DCI) message carrying indication information, wherein the indication information is configured to indicate to switch a state of resource configuration information of a reference signal from an unavailable state to an available state, in which the resource configuration information indicates at least transmission resources of the reference signal;
in response to the indication information being configured to indicate the resource configuration information to switch from the unavailable state to the available state, maintaining the resource configuration information in the available state within a validity duration; and
sending duration information carrying the validity duration, wherein the validity duration is N discontinuous reception (DRX) cycles.
2 . The method of claim 1 , wherein
the validity duration is pre-configured by a network device; or
the validity duration is specified in a communication protocol.
3 . The method of claim 1 , wherein
the validity duration is continuous in a time domain; or
the validity duration comprises at least two sub-validity durations that are discontinuous in a time domain.
4 . The method of claim 1 , wherein the reference signal comprises at least one of: a channel state information reference signal (CSI-RS); a synchronization signal and physical broadcast channel block (SSB); or a tracking reference signal (TRS).
5 . A base station, comprising: a processor, and a memory storing instructions executable by the processor; wherein when the instructions are executed by the processor, the method according to claim 1 is implemented.
6 . The method of claim 1 , wherein the DCI message is a paging DCI or a power-saving signal.
7 . A method for information transmission, performed by a user equipment (UE), the method comprising:
receiving a downlink control information (DCI) message carrying indication information, wherein the indication information is configured to indicate to switch a state of resource configuration information of a reference signal from an unavailable state to an available state, in which the resource configuration information indicates at least transmission resources of the reference signal;
in response to the indication information being configured to indicate the resource configuration information to switch from the unavailable state to the available state, determining the resource configuration information is in the available state within a validity duration;
receiving duration information carrying the validity duration, wherein the validity duration is N discontinuous reception (DRX) cycles.
8 . The method of claim 7 , wherein
the validity duration is pre-configured by a network device; or the validity duration is specified in a communication protocol.
9 . The method of claim 7 , wherein
the validity duration is continuous in a time domain; or
the validity duration comprises at least two sub-validity durations that are discontinuous in a time domain.
10 . The method of claim 7 , wherein the reference signal comprises at least one of: a channel state information reference signal (CSI-RS); a synchronization signal and physical broadcast channel block (SSB); or a tracking reference signal (TRS).
11 . The method of claim 7 , wherein the DCI message is a paging DCI or a power-saving signal.
12 . A user equipment (UE), comprising: a processor, and a memory storing instructions executable by the processor; wherein when the instructions are executed by the processor, the processor is configured to:
receive a downlink control information (DCI) message carrying indication information, wherein the second indication information is configured to indicate to switch a state of resource configuration information of a reference signal from an unavailable state to an available state, in which the resource configuration information indicates at least transmission resources of the reference signal;
in response to the indication information being configured to indicate the resource configuration information to switch from the unavailable state to the available state, determine the resource configuration information is in the available state within a validity duration;
receive duration information carrying the validity duration, wherein the validity duration is N discontinuous reception (DRX) cycles.
13 . The UE of claim 12 , wherein the DCI message is a paging DCI or a power-saving signal.
