Techniques for radio resource management (RRM) in sidelink wireless communications
Some aspects described herein relate to receiving and/or forwarding radio resource management (RRM) configurations for sidelink reporting, as well as measuring sidelink signals and generating measurement reports for reporting to the network.
1 . A method for wireless communication, comprising:
receiving, by a first device, a radio resource measurement (RRM) configuration for measuring and reporting signals received from one or more devices in sidelink resources;
receiving, by the first device and from a second device over a sidelink, an indication to switch communications from one of:
a first component carrier to a second component carrier; or
a first bandwidth part (BWP) to a second BWP;
measuring, based on the RRM configuration, signals received from the one or more devices over the second component carrier or the second BWP; and
transmitting, to a base station and based on the RRM configuration, a report of one or more signal parameters of the measured signals, wherein the report includes an identifier of the second device and at least one of a component carrier index of the second component carrier, or a BWP identifier of the second BWP.
2 . The method of claim 1 , wherein receiving the RRM configuration comprises receiving the RRM configuration from the second device over the sidelink.
3 . The method of claim 2 , wherein receiving the RRM configuration comprises receiving the RRM configuration from the second device using PC5 radio resource control (RRC) signaling.
4 . The method of claim 1 , wherein receiving the RRM configuration comprises receiving the RRM configuration from the base station.
5 . The method of claim 1 , wherein receiving the RRM configuration comprises receiving the RRM configuration from the base station in radio resource control (RRC) signaling.
6 . The method of claim 1 , wherein receiving the RRM configuration comprises receiving the RRM configuration from the base station in a system information block (SIB).
7 . The method of claim 1 , wherein the RRM configuration indicates at least one of a periodic timer for periodic measuring and reporting of the signals received from the one or more devices, a trigger condition or event type for determining to measure and report the signals received from the one or more devices, a layer 3 filter coefficient for a cell or beam, or a report quantity to include in the reporting of the signals received from the one or more devices.
8 . An apparatus for wireless communication, comprising:
a transceiver;
a memory configured to store instructions; and
one or more processors communicatively coupled with the transceiver and the memory, wherein the one or more processors are configured to:
receive a radio resource measurement (RRM) configuration for measuring and reporting signals received from one or more devices in sidelink resources;
receive, from a second apparatus over a sidelink, an indication to switch communications from one of:
a first component carrier to a second component carrier; or
a first bandwidth part (BWP) to a second BWP;
measure, based on the RRM configuration, signals received from the one or more devices over the second component carrier or the second BWP; and
transmit, to a base station and based on the RRM configuration, a report of one or more signal parameters of the measured signals, wherein the report includes an identifier of the second device and at least one of a component carrier index of the second component carrier, or a BWP identifier of the second BWP.
9 . The apparatus of claim 8 , wherein the one or more processors are configured to receive the RRM configuration from the second apparatus over the sidelink.
10 . The apparatus of claim 9 , wherein the one or more processors are configured to receive the RRM configuration from the second apparatus using PC5 radio resource control (RRC) signaling.
11 . The apparatus of claim 8 , wherein the one or more processors are configured to receive the RRM configuration from the base station.
12 . The apparatus of claim 8 , wherein the one or more processors are configured to receive the RRM configuration from the base station in radio resource control (RRC) signaling.
13 . The apparatus of claim 8 , wherein the one or more processors are configured to receive the RRM configuration from the base station in a system information block (SIB).
14 . The apparatus of claim 8 , wherein the RRM configuration indicates at least one of a periodic timer for periodic measuring and reporting of the signals received from the one or more devices, a trigger condition or event type for determining to measure and report the signals received from the one or more devices, a layer 3 filter coefficient for a cell or beam, or a report quantity to include in the reporting of the signals received from the one or more devices.
