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 broadcast message associated with initial access. The UE may monitor, for an additional message from the base station, a set of monitoring occasions that are non-consecutive across slots, based at least in part on the broadcast message. In some aspects, the set of monitoring occasions are non-consecutive across slots based at least in part on a stored rule that uses a subcarrier spacing. Numerous other aspects are described.

Abstract: Apparatus, methods, and computer program products for SCS RO alignment are provided. An example method includes transmitting, to a base station, a physical random access channel (PRACH) preamble in one RACH occasion (RO) in a first set of ROs in one or more PRACH slots associated with a first subcarrier spacing (SCS), the one or more PRACH slots being within a duration defined based on a PRACH slots time duration for a second subcarrier spacing (SCS). The example method further includes receiving, from the base station, a PRACH response.

Abstract: The present disclosure provides systems, methods, and apparatuses for grouping beams that are directionally associated with one another and associating respective properties associated with groups of beams. In one aspect, a UE or component thereof may be configured to select a first beam group of one or more beam groups to include a first beam of a set of beams, with the first beam group including a first subset of beams of the set of beams that is directionally associated with a first direction of the first beam. The UE or component thereof may be further configured to associate a respective set of properties with each of the one or more beam groups. The UE or component thereof be configured to communicate via the first beam of the first beam group of the one or more beam groups.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may measure, for a first beam group of a set of beam groups associated with the UE, a first channel busy ratio (CBR) for the first beam group. The UE may receive, from a second UE, an indication of a second CBR for a second beam group associated with the second UE. The UE may transmit, to the second UE using a beam included in the first beam group, a signal using one or more transmit parameters that are based at least in part on at least one of the first CBR or the second CBR. Numerous other aspects are described.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may receive, from a network entity, one or more synchronization signal block (SSB) transmissions associated with a first subcarrier spacing (SCS). The UE may receive, from the network entity, one or more initial access transmissions associated with a second SCS, wherein a time location of an initial access transmission, of the one or more initial access transmissions, that uses a beam is based at least in part on a time location of an SSB transmission, of the one or more SSB transmissions, that uses the beam. Numerous other aspects are described.

IPC: H04W52/30

Abstract: Disclosed are systems and techniques for performing sidelink communications. For instance, a first client device can determine a first transmit power parameter for transmitting sidelink communications. The first transmit power parameter can either be received from a base station associated with the first client device or it can be a default parameter based on the first client device not being associated with a base station. The first client device can transmit, to a second client device, a first sidelink transmission having a first power level corresponding to the first transmit power parameter. The first client device can receive, from the second client device, a first sidelink reception having a second power level corresponding to a second transmit power parameter.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a wireless communication device (WCD) may communicate, during a channel occupancy time (COT) associated with one or more resources, via a no listen before talk (no-LBT) channel access mode. The WCD may initiate, after the COT, a reduced COT associated with the one or more resources, wherein the WCD is configured to reduce channel occupancy during the reduced COT. Numerous other aspects are described.

Abstract: A first UE in a UE group may determine that a sidelink channel is available for data transmission and transmit SCI reserving a COT on the sidelink channel. A second may receive, from the first UE, the SCI reserving the COT on the sidelink channel and transmitting the sidelink transmission on the sidelink channel using one or more resources of the inter-group sharable resources. The COT may include a first set of resources reserved for the first UE, an intra-group sharable resources capable of being shared by the UE group, and an inter-group sharable resources capable of being shared by the second UE outside of the UE group. The second UE may perform the CAT 1 or CAT 2 LBT procedure to contend for the inter-group sharable resources. The access to the inter-group sharable resources may be limited.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a wireless communication device may transmit an announcement that indicates a plurality of future resource reservations. The wireless communication device may transmit multiple sets of announcements that indicate one or more reservations and may vary the transmission frequency thereof based on proximity to the communications. The wireless communication device may transmit an announcement that indicates a future communication and a cancellation indication that indicates a cancellation of the communication. The wireless communication device may transmit a preemption indication that indicates that resources reserved for an announced future communication have been preempted for another communication. Numerous other aspects are described.

Abstract: Wireless communications systems and methods are provided. A method of wireless communication may include performing a first listen-before-talk (LBT) procedure associated with a channel, wherein a channel occupancy time (COT) for the channel is acquired based on the first LBT being successful, communicating a first communication signal in a first link direction during the COT, switching from the first link direction to a second link direction different from the first link direction, and communicating after the switching, a second communication signal in the second link direction without performing a second LBT.
