Abstract: Aspects described herein relate to receiving at least one indication of a capability to simultaneously transmit using two different radio access technology (RAT) sidelinks over respective frequency bands, receiving a time delta indication specifying a time delta from the time a sidelink grant, corresponding to a first RAT sidelink of the two different RAT sidelinks, is received to the time when resources of the sidelink grant can be used by the UE, and transmitting, based on receiving the time delta indication, at least one of the sidelink grant or a second sidelink grant for a second RAT sidelink of the two different RAT sidelinks.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may select, in a first time slot, a set of resources to use for transmission to another UE; evaluate, in a second time slot, whether one or more resources of the set of resources is available; and transmit, based on the one or more resources of the set of resources being available, information to the other UE in a third time slot and using the set of resources, or reselect, based on the one or more resources of the set of resources being unavailable, another resource for transmission of the information to the other UE. Numerous other aspects are provided.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may receive, from a base station, a discontinuous reception (DRX) configuration to be used by the UE for cellular communication with the base station, wherein the DRX configuration indicates a DRX cycle that includes an active time during which the UE is to monitor a physical downlink control channel (PDCCH) and an inactive time during which the UE is to refrain from monitoring the PDCCH; identify a time window for sidelink communication with another UE based at least in part on the DRX configuration; and communicate using one or more sidelink resources in the identified time window. Numerous other aspects are provided.

Abstract: Disclosed are techniques for wireless communication. In an aspect, a first user equipment (UE) performs a limited beam sweep of one or more transmit beams on a second frequency band in an estimated direction from the first UE to the second UE, wherein the estimated direction is based on one or more parameters received over a previously established signaling radio bearer (SRB) on a first frequency band and/or a device-to-device discovery procedure performed on the first frequency band, receives, over the SRB, a confirmation that a data radio bearer (DRB) has been established on the second frequency band with at least one transmit beam of the one or more transmit beams, and sends, to the second UE, a data flow over the DRB on the second frequency band using the at least one transmit beam.

Abstract: Certain aspects of the present disclosure provide techniques for receiver side protection in sidelink communications. In certain aspects, a method performed by an apparatus generally includes obtaining, from a first user equipment (UE), first control information, which includes a first resource allocation information of one or more resources allocated for transmission by the first UE to the apparatus and an indication of a first cell associated with the first UE. The method generally includes obtaining, from a second UE, second control information, which generally includes a second resource allocation information of resources allocated for transmission by the second UE to the apparatus and an indication of a second cell associated with the second UE. The method generally includes determining, based on the first and second control information, potential interference from transmissions by the first UE and the second UE and taking one or more actions to mitigate the potential interference.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may identify multiple candidate sets of physical sidelink feedback channel (PSFCH) transmissions that include hybrid automatic repeat request (HARQ) feedback for sidelink communications received from one or more peer UEs. The UE may select, from one or more of the multiple candidate sets that satisfy a PSFCH transmit power constraint, at least one candidate set that has a highest value for a utility parameter among utility parameters associated with each of the one or more candidate sets that satisfy a PSFCH transmit power constraint. The UE may transmit, on a PSFCH, the plurality of PSFCH transmissions included in the at least one candidate set in a HARQ feedback occasion. Numerous other aspects are provided.

Abstract: Methods, systems, and devices for wireless communications are described. A user equipment (UE) may determine to operate as a relay UE based on a set of thresholds configured for the first UE. The UE may transmit a relay discovery announcement on a communication channel of a sidelink to indicate support for relay communications. A remote UE may monitor for and receive the relay discovery announcement on the sidelink communications channel. The remote UE may select the relay UE based on a set of criteria for selecting a candidate relay UE. The remote UE and the relay UE may establish the relay communications based on the relay discovery announcement transmitted on the communications channel of the relay sidelink.

Abstract: Various aspects of the disclosure relate to limits for modulation and coding scheme (MCS) values. For example, a first set of limits (e.g., minimum and maximum limits) may be used for a first MCS table and a second set of limits may be used for a second MCS table. The disclosure also relates in some aspects to inter-device signaling that indicates which minimum and maximum limits for an MCS table are to be used for communication between the devices.

Abstract: Apparatus and methods for S-SSB transmission are provided. In an aspect, an S-SSS symbol is followed by a gap symbol. In another aspect, a first PSBCH symbol is followed by an S-SSS symbol. In a further aspect, the same MPR is used for the entire S-SSB, thus reducing/mitigating transient periods. For example, the S-SSS symbols in the S-SSB may be selected from a set of sequences having the same MPR as the S-PSS symbols. Alternatively, the MPR of the entire S-SSB may be selected based on a sequence ID of an S-SSS. In an aspect, additional symbols may be configured in the S-SSB to compensate for power reduction.
