Abstract: Methods, systems, and devices for wireless communications are described. A base station may transmit one or more synchronization signal blocks (SSBs), each SSB including a system information block (SIB), to one or more user equipments (UEs). A UE of the one or more UEs may select an SSB with a corresponding SSB index for receiving a SIB and subsequently a multicast transmission from the base station. The multicast transmission may include transmitting a multicast control channel, a multicast traffic channel, or both. The SIB may include one or more parameters for receiving the multicast transmission. The UE may identify one or more monitoring occasions for monitoring a physical downlink control channel for scheduling the multicast transmission based on the SSB index. The UE may receive the multicast transmission in accordance with the one or more parameters from the physical downlink control channel during the one or more monitoring occasions.

Abstract: Methods, systems, and devices for wireless communications are described. An integrated access and backhaul (IAB) node may receive, from a parent IAB node, a channel state information (CSI) report configuration for generation of a CSI report associated with monitoring, by the IAB node, at least one CSI-reference signal (CSI-RS) resource set, the configuration also indicating usage information for the at least one CSI-RS resource set. The IAB node may transmit a CSI resource configuration to a downstream node, the CSI resource configuration indicating, based at least in part on the usage information, a number of spatial layers of cross-link interference associated with the parent IAB node. The IAB node may receive, from the downstream node, the CSI report indicating CSI, the CSI associated with the cross-link interference based at least in part on the number of spatial layers.

Abstract: Methods, systems, and devices for wireless communications are described. A user equipment (UE) may transmit a scheduling request to a base station using the dedicated uplink resources. The UE may transmit the scheduling request to indicate that a group of UEs requests uplink resources for an uplink data transmission. As a result, the UE may receive downlink control information from a base station which includes corresponding uplink resources allocated to the UE based on the scheduling request. The UE may use the allocated uplink resources to transmit uplink data to the base station.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may determine a starting symbol of a radio frequency (RF) retuning gap between a first plurality of repetitions of an uplink transmission in a first frequency hop and a second plurality of repetitions of the uplink transmission in a second frequency hop. The starting symbol of the RF retuning gap is based at least in part on a starting symbol of the second plurality of repetitions and a quantity of symbols included in the RF retuning gap. The UE may determine an ending symbol of the RF retuning gap based at least in part on the starting symbol of the second plurality of repetitions. The UE may perform RF retuning during the RF retuning gap. Numerous other aspects are provided.
