Information transmission method and apparatus, and communication device and storage medium
A method for information transmission includes: receiving a first request message carrying a recommended positioning reference signal (PRS) configuration; determining a target PRS configuration according to the recommended PRS configuration; and sending a PRS to a user equipment by using the target PRS configuration.
1 . A method for information transmission, performed by a base station, comprising:
sending system information, wherein the system information carries at least one available positioning reference signal (PRS) configuration, the at least one available PRS configuration is configured for a user equipment (UE) to determine a recommended PRS configuration, and each available PRS configuration carries a configuration identifier of the available PRS configuration, wherein the at least one available PRS configuration is carried in a type 6-1 of the system information;
receiving a first request message carrying the recommended PRS configuration;
determining a target PRS configuration according to the recommended PRS configuration; and
sending a PRS to the UE using the target PRS configuration.
2 . The method of claim 1 , wherein receiving the first request message carrying the recommended PRS configuration comprises:
receiving the first request message carrying a configuration identifier of the recommended PRS configuration.
3 . The method of claim 1 , further comprising:
sending the target PRS configuration to the UE in response to the first request message, wherein the target PRS configuration is configured to indicate the UE to receive the PRS.
4 . The method of claim 1 , wherein receiving the first request message-carrying the recommended PRS configuration comprises:
receiving the first request message carrying the recommended PRS configuration, sent by the UE in an on-demand manner.
5 . The method of claim 4 , wherein receiving the first request message carrying the recommended PRS configuration, sent by the UE in the on-demand manner, comprises one of:
receiving a dedicated system information block request carrying the recommended PRS configuration; or
receiving a dedicated radio resource control system information request carrying the recommended PRS configuration.
6 . A method for information transmission, performed by a user equipment (UE), comprising:
receiving system information, wherein the system information carries at least one available positioning reference signal (PRS) configuration, and each available PRS configuration carries a configuration identifier of the available PRS configuration;
determining a recommended PRS configuration from the at least one available PRS configuration, wherein the at least one available PRS configuration is carried in a type 6-1 of the system information;
sending a first request message carrying the recommended PRS configuration, wherein the recommended PRS configuration is configured for a base station to determine a target PRS configuration; and
receiving a PRS sent by the base station based on the target PRS configuration.
7 . The method of claim 6 , wherein sending the first request message carrying the recommended PRS configuration comprises:
sending the first request message carrying a configuration identifier of the recommended PRS configuration.
8 . The method of claim 6 , further comprising:
determining a predetermined PRS configuration as the recommended PRS configuration in response to not receiving the system information.
9 . The method of claim 6 , wherein receiving the PRS sent by the base station based on the target PRS configuration comprises:
receiving the target PRS configuration, sent by the base station in response to the first request message; and
receiving the PRS from the base station based on the received target PRS configuration.
10 . The method of claim 6 , wherein sending the first request message carrying the recommended PRS configuration comprises:
sending the first request message carrying the recommended PRS configuration in an on-demand manner.
11 . The method of claim 10 , wherein sending the first request message carrying the recommended PRS configuration in the on-demand manner comprises one of:
sending a dedicated system information block request carrying the recommended PRS configuration; or
sending a dedicated radio resource control system information request carrying the recommended PRS configuration.
12 . A communication device, comprising:
a processor;
a transceiver; and
a memory storing a program executable by the processor,
wherein the processor is configured to:
send system information, wherein the system information carries at least one available positioning reference signal (PRS) configuration, the at least one available PRS configuration is configured for a user equipment (UE) to determine a recommended PRS configuration, and each available PRS configuration carries a configuration identifier of the available PRS configuration, wherein the at least one available PRS configuration is carried in a type 6-1 of the system information;
receive a first request message carrying the recommended PRS configuration;
determine a target PRS configuration according to the recommended PRS configuration; and
send a PRS to the UE using the target PRS configuration.
13 . A non-transitory storage medium having stored thereon a program that, when executed by a processor, causes the processor to perform the method of claim 1 .
14 . A communication device, comprising:
a processor;
a transceiver; and
a memory storing a program executable by the processor,
wherein the processor is configured to perform the method of claim 6 .
15 . The method of claim 1 , wherein the first request message comprises:
a first information element (IE) comprising the recommended PRS configuration; and
a second IE comprising a request of triggering system information.
16 . The method of claim 6 , wherein the first request message comprises:
a first information element (IE) comprising the recommended PRS configuration; and
a second IE comprising a request of triggering system information.
