Abstract: Aspects of the present disclosure provide techniques for configuring a search space for sidelink communications between a plurality of user equipments (UEs). Particularly, the techniques described herein configure a search space (e.g., subset of all available sub-channels) to decode the sidelink packets (e.g., physical sidelink control channel (PSCCH) and physical sidelink shared channel (PSSCH)) transmitted between a first UE and a second UE over sidelink communication without the need for the receiver UE (e.g., second UE) to perform blind decoding of all sidelink sub-channels as is currently required in conventional systems. Thus, the disclosed techniques reduce latency and maximize the resource utilization (e.g., by using less processing power and bandwidth) for sidelink communications

Abstract: Aspects relate to a wireless communication device that forwards signals over different types of wireless communication links. For example, a wireless communication device may be configured to relay signals for a first type of wireless communication link (e.g., a cellular link such as a Uu link) and also relay signals for a second type of wireless communication link (e.g., a sidelink that uses a PC5 link). The disclosure relates in some aspects to techniques for configuring the wireless communication device to enable the signals for the different types of wireless communication links to be forwarded in an effective manner.
