Abstract

Methods, systems, and devices for wireless communication are described to support configuring a user equipment (UE) operating in unlicensed spectrum with a set of component carriers (CCs) for sidelink communications using the unlicensed spectrum. In a first example, a UE may select a CC from the set of candidate CCs, for example, using a carrier selection configuration, and may select a resource in the CC for a sidelink communication. In a second example, a UE may select multiple candidate resources for a sidelink communication, for example, using a resource selection configuration and based on sensing performed by the UE. To indicate the reservation of a candidate resource, the UE may indicate both a CC in which the reserved resource is located and a location of the reserved resource within the carrier. The UE may transmit a sidelink message using a selected candidate resource in the unlicensed spectrum.

Abstract

Aspects relate to communication using multiple antenna panels. A first user equipment (UE) may use an antenna panel of a second UE for receiving and/or transmitting data. For example, a network entity may schedule a transmission to the first UE where a first transmit receive point (TRP) transmits data to a first antenna panel of the first UE via a first TRP and simultaneously transmits data to a second antenna panel of the second UE via a second TRP, whereby the second UE forwards the data it receives to the first UE. The first UE may send antenna panel information to the network entity for scheduling a multi-panel transmission or reception for the first UE. The first UE may send a request to the second UE to forward data for a multi-panel transmission or reception.
