Abstract

This application discloses a reference signal configuration method and apparatus and a terminal. The method includes: determining a first configuration of a first reference signal and/or a first configuration state of the first configuration when the terminal is in an idle or inactive state, where the first configuration state includes at least one of the following: valid, available, activated, invalid, unavailable, and deactivated.

Claims (41)

1 . A reference signal configuration method, executed by a terminal and comprising:

determining a first configuration state of a first configuration of a first reference signal when the terminal is in an idle or inactive state, wherein the first configuration state comprises at least one of the following: valid, available, activated, invalid, unavailable, and deactivated;

wherein the determining a first configuration state of a first configuration of a first reference signal when the terminal is in an idle or inactive state comprises:

determining the first configuration state of the first configuration when the terminal is in an idle or inactive state, according to target indication, wherein

the target indication comprises an early indication signal indication.

2 . The method according to claim 1 , wherein before the determining a first configuration state of a first configuration of a first reference signal, the method further comprises:

releasing a radio resource control (RRC) connected state to enter the idle state; or

suspending an RRC connected state to enter the inactive state.

3 . The method according to claim 1 , wherein the early indication signal comprises at least one of the following: a wake-up signal, a go-to-sleep signal, a paging response, a paging indication, and a paging early indication.

4 . The method according to claim 1 , wherein the target indication is further used for determining at least one of when the first configuration of the first reference signal is valid, available, activated, invalid, unavailable, and deactivated.

5 . The method according to claim 1 , wherein in a case that the first configuration is a first reference signal configuration configured by a network side under the connected state, the target indication is further used to indicate that the first configuration state of the first configuration is to be effective.

6 . The method according to claim 1 , wherein the first configuration state of the first configuration becomes effective upon receipt of the target indication.

7 . The method according to claim 1 , wherein the first configuration state of the first configuration becomes effective upon receipt of the first configuration of the first reference signal.

8 . The method according to claim 7 , wherein the first configuration state of the first configuration ends when a first condition is met, wherein

the first condition comprises at least one of the following:

a first predetermined timer has expired;

a first preset duration has elapsed;

a target indication for indicating the first configuration state of the first configuration has been received; and

a second configuration of the first reference signal has been received, wherein the second configuration is partially or totally different from the first configuration.

9 . The method according to claim 7 , wherein in a case that the first configuration of the first reference signal is configured through an RRC release or RRC suspend message, the first configuration state of the first configuration becomes effective upon receipt of the first configuration of the first reference signal.

10 . The method according to claim 1 , wherein the first configuration of the first reference signal is a configuration made by the network side for a first reference signal of the terminal being in an RRC connected state.

11 . The method according to claim 10 , wherein the determining a first configuration state of a first configuration of a first reference signal when the terminal is in an idle or inactive state comprises:

the first configuration state of the first configuration becomes effective when the terminal is released to an idle state or suspended to an inactive state.

12 . The method according to claim 10 , wherein the first configuration state of the first configuration ends when a second condition is met, wherein

the second condition comprises at least one of the following:

a second predetermined timer has expired;

a second preset duration has elapsed;

a target indication for indicating the first configuration state of the first configuration has been received; and

a second configuration of the first reference signal has been received, wherein the second configuration is partially or totally different from the first configuration.

13 . The method according to claim 1 , wherein the first reference signal is a reference signal configured by a network for connected-state UE.

14 . The method according to claim 13 , wherein the first reference signal comprises at least one of the following: a channel state information reference signal, a demodulation reference signal, a tracking reference signal, a positioning reference signal, and a second synchronization signal and PBCH block, wherein the second synchronization signal and PBCH block is different from a first synchronization signal and PBCH block received by an idle-state terminal.

15 . A terminal, comprising a processor, a memory, and a program or instructions stored in the memory and run on the processor, wherein the program or instructions are executed by the processor to perform:

determining a first configuration state of a first configuration of a first reference signal when the terminal is in an idle or inactive state, wherein the first configuration state comprises at least one of the following: valid, available, activated, invalid, unavailable, and deactivated;

wherein the determining a first configuration state of a first configuration of a first reference signal when the terminal is in an idle or inactive state comprises:

determining the first configuration state of the first configuration when the terminal is in an idle or inactive state, according to target indication, wherein

the target indication comprises an early indication signal indication.

16 . A readable storage medium, wherein the readable storage medium stores a program or instructions, and the program or the instructions are executed by a processor to perform:

determining a first configuration state of a first configuration of a first reference signal when the terminal is in an idle or inactive state, wherein the first configuration state comprises at least one of the following: valid, available, activated, invalid, unavailable, and deactivated;

wherein the determining a first configuration state of a first configuration of a first reference signal when the terminal is in an idle or inactive state comprises:

determining the first configuration state of the first configuration when the terminal is in an idle or inactive state, according to target indication, wherein

the target indication comprises an early indication signal indication.
