Abstract: Aspects are provided for HARQ feedback and retransmission procedures for cooperative relaying in sidelink networks. A relay attempts to decode sidelink data received from a source for relay to a destination. The relay may combine LLRs for the sidelink data and for a retransmission of the sidelink data. The relay determines a resource of a wireless channel for transmitting feedback to the source in response to the decoding attempt. If decoding is successful, the relay transmits the data to the destination. The destination then attempts to decode the data received from the relay. The destination may combine LLRs for the data and for a retransmission of the data. The destination determines a resource of a wireless channel for transmitting feedback to the relay in response to the decoding attempt. The resources are based on a relay identifier associated with the relay.

Abstract: A target user equipment (UE) may receive, from each relay UE of a set of relay UEs, a synchronization signal block (SSB) through each transmit beam of a set of transmit beams from the UE through each receive beam of a set of receive beams at the target UE. The relay UE may transmit the paging message through each transmit beam of the set of transmit beams. The target UE may determine a beam pair based on the received SSB, and receive the paging messaged using the beam pair. The target UE may also receive, from a relay UE, a paging message through one or more sidelink channels from each transmit beam of a set of transmit beams of the relay UE through each receive beam of a set of receive beams at the target UE and decode the received paging message.

Abstract: Methods, systems, and devices for wireless communication are described. Generally, the described techniques provide for efficiently transmitting data and control information in a first RACH message to a base station as part of a two-step RACH procedure. In particular, rather than or in addition to transmitting data and control information in a physical uplink shared channel (PUSCH) in the first RACH message, a user equipment (UE) may transmit the data and control information along with a RACH preamble in a RACH occasion in the first RACH message (e.g., when the number of bytes of data or control information to be transmitted is low). Using these techniques, in some instances, the UE may transmit the data and control information in a first RACH message without transmitting the PUSCH, and the overhead associated with transmitting the PUSCH may be eliminated.
