US 2023/0422218 A1 · CHANNEL RESTRICTIONS FOR RELAYED SIDELINK COMMUNICATIONS

Abstract

Methods, systems, and devices for wireless communications are described to support relayed sidelink communications. A first device and a base station may communicate via a communication link including a sidelink link between the first device and a second device and a relay link between the second device and the base station. The base station may determine restrictions for the communication link and transmit an indication of the restrictions over the relay link. The restrictions may differentiate data originating from the first device and the second device, restrict the first device to one or more resources, or associate logical channels at the first device with one or more transport block sizes and communication links. The second device may relay the indication of the restrictions to the first device. The first device, the second device, and the base station may communicate over the communication link according to the restrictions.

Dependent claims

An apparatus for wireless communication at a first device, comprising:

one or more memories;
and
one or more processors coupled with the one or more memories and configured to cause the first device to:
receive an indication of one or more logical channel prioritization restrictions corresponding to a sidelink communication link between the first device and a second device, the one or more logical channel prioritization restrictions based at least in part on an identity of the second device;
transmit, over the sidelink communication link, the indication of the one or more logical channel prioritization restrictions;
and
communicate over the sidelink communication link in accordance with the one or more logical channel prioritization restrictions.

4 more elements

An apparatus for wireless communication at a second device, comprising:

one or more memories;
and
one or more processors coupled with the one or more memories and configured to cause the second device to:
receive, over a sidelink communication link between the second device and a first device, an indication of one or more logical channel prioritization restrictions corresponding to the sidelink communication link, the one or more logical channel prioritization restrictions based at least in part on an identity of the second device;
and
communicate over the sidelink communication link in accordance with the one or more logical channel prioritization restrictions.

3 more elements

An apparatus for wireless communication at a network node, comprising:

one or more memories;
and
one or more processors coupled with the one or more memories and configured to cause the network node to:
determine one or more logical channel prioritization restrictions corresponding to a sidelink communication link between a first device and a second device, the one or more logical channel prioritization restrictions based at least in part on an identity of the second device;
and
transmit, over a communication link between the network node and the first device, an indication of the one or more logical channel prioritization restrictions.

Classification16 codes

H04W 72/02
Local resource management: selection of wireless resources by user or terminal
H04L 5/0053
Arrangements for allocating sub-channels of the transmission path: allocation of signalling, i.e. of overhead other than pilot signals
H04L 5/0064
Allocation criteria: rate requirement of the data, e.g. scalable bandwidth, data priority
H04W 72/0453
Based on the type of the allocated resource: resources in frequency domain, e.g. a carrier in FDMA
