    Abstract: Methods, systems, and devices for wireless communications are described. A wireless device may monitor for a transmission of a synchronization signal block that includes a first portion generated using a first waveform type and a second portion using a second waveform type that is different than the first waveform type. The wireless device may detect the first portion of the synchronization signal block based on the first waveform type used for the first portion. After detecting the first portion of the synchronization signal block, the wireless device may process the second portion of the synchronization signal block based on information obtained from the first portion of the synchronization signal block. The information obtained from the first portion of the synchronization signal block may include timing information, frequency information, or both.

    Abstract: Methods, systems, and devices for sidelink groupcast communications are described. A user equipment (UE) may transmit a beam training request to a base station to determine beams for use with other UEs in a sidelink groupcast communications group. The base station may receive the beam training request, identify wireless resources that a group of UEs may use to perform beam training, and may transmit a beam training grant to each UE of the group of UEs. The UE may transmit a number of training beams using the wireless resources provided in the beam training grant, and the other UEs may measure received signals on the wireless resources to identify one or more beams. Each UE may provide a beam training report to the base station. The base station, based on the beam training reports, may determine beams and resources for use in the groupcast sidelink communications.

    Abstract: This disclosure relates to a relay node, and a method of wireless communications by the relay node, including attempting to decode a plurality of first transport block portions of a transport block, wherein the plurality of first transport block portions are received on a first link according to a first encoding configuration. The aspects further include encoding successfully decoded ones of the plurality of first transport block portions according to a second encoding configuration to define one or more second transport block portions corresponding to the transport block, wherein the second encoding configuration is different from the first encoding configuration. And, the aspects further include transmitting the one or more second transport block portions on a second link and according to the second encoding configuration. Other aspects of the relay node and a receiver node are also disclosed.

    Abstract: In one aspect of the disclosure, a UE may be configured to receive, from a base station, information indicating a reference point associated with at least one L1 measurement; determine a reporting value of the at least one L1 measurement based on a difference between the reference point and a measured value of the at least one L1 measurement; and transmit information indicating the reporting value to the base station. In another aspect, a RAN node can indicate to a UE that a reduced measurement report resolution is to be used for beam measurements in a measurement report. The reduced measurement report resolution is less than a first measurement report resolution previously indicated to be used for the beam measurements. Lower resolution can be obtained by using fewer bits to indicate one or more of the beam measurements. The payload for a measurement report such as a L-SINR or L-RSP L1 measurement report is thereby reduced when the UE transmits the measurement report to the RAN node.

    Abstract: Aspects relate to mechanisms for wireless communication devices to update transmission configuration indicator states (TCI-states), spatial relation (SR) indicators (SRIs), or pathloss reference signals (PL-RSs) for a group of two or more component carriers (CCs) for multi-component carrier communication. A radio access network (RAN) node may generate a message indicating one or more TCI-states, one or more SRs, or one or more PL-RSs to utilize for multi-CC communication. The message may include an index identifying a group of two or more CCs of a plurality of access CCs or a plurality of sidelink CCs associated with the one or more TCI-states, the one or more SRs, or the one or more PL-RSs. A user equipment (UE) may receive the message and update the one or more TCI-states, the one or more SRs, or the one or more PL-RSs for the group of two or more CC for the multi-CC communication based on the message.
