US 11,457,431 B2 · Sidelink radio resource allocation

Abstract

A method for a first user equipment (UE) to exchange one or more sidelink packets with a second UE. The method receives, from a serving base station, a sidelink resource allocation configuration that includes i) one or more sidelink resource configurations on one or more sidelink frequency carriers, and (ii) data identifying a valid area of the sidelink resource configurations. The method determines, based on the data identifying the valid area, whether the first UE is located within the valid area. If the method determines that the first UE is located within the valid area, the method exchanges the one or more sidelink packets with the second UE based on the received sidelink resource allocation configuration, otherwise, the method stops exchanging the one or more sidelink packets, on one or more sidelink resources indicated by the sidelink resource configurations, with the second UE.

Dependent claims

A method by a user equipment (UE) in a radio resource control (RRC) Inactive state, the method comprising:

triggering an RRC Connection Resume procedure to request a first sidelink resource allocation configuration, after determining that new radio (NR) or long-term evolution (LIE) sidelink system information that comprises second resource allocation configuration and is stored in the UE is still valid, wherein the first sidelink resource allocation configuration comprises one or more UE-specific dedicated sidelink resource configurations on one or more sidelink frequency carriers and is requested to update the stored second resource allocation configuration in the sidelink system information;
and
transmitting an RRC resume request message to a serving cell based on the triggered RRC Connection Resume procedure to move the UE from the RRC Inactive state to an RRC Connected state.

A user equipment (UE) in a radio resource control (RRC) Inactive state, the UE comprising:

one or more non-transitory computer-readable media storing computer-executable instructions for scheduling sidelink transmission resources for the UE to exchange one or more sidelink packets with another UE;
and
at least one processor coupled to the one or more non-transitory computer-readable media, and configured to execute the computer-executable instructions to:
trigger an RRC Connection Resume procedure to request a first sidelink resource allocation configuration, after determining that new radio (NR) or long-term evolution (LTE) sidelink system information that comprises second resource allocation configuration and is stored in the UE is still valid, wherein the first sidelink resource allocation configuration comprises one or more UE-specific dedicated sidelink resource configurations on one or more sidelink frequency carriers and is requested to update the stored second resource allocation configuration in the sidelink system information;
and
transmit an RRC resume request message to a serving cell based on the triggered RRC Connection Resume procedure to move the UE from the RRC Inactive state to an RRC Connected state.
