Methods, systems, and devices for wireless communication are described to support indication of a single frequency network (SFN) mode and associated parameters to a user equipment (UE), while the UE is operating in an idle mode. While operating in the idle mode, the UE may receive signaling from a transmission reception points (TRP), indicating that an SFN will be used for broadcast signaling received concurrently from multiple TRPs. Based on receiving the indication of the SFN, the UE may receive the broadcast signaling via a downlink control channel. For example, the UE may receive the broadcast signaling concurrently from a first TRP via a first beam and from a second TRP via a second beam, where the first and second beams may each be associated with a respective synchronization signal block (SSB).

Beam identification for paging messages on a single frequency network

Aspects provide communication methods, apparatuses and computer-readable mediums. According to an aspect, there is provided a method for wireless communication at a network entity. The method comprises: splitting a first individual message associated with a first device into at least a first common part and a first private part; splitting a second individual message associated with a second device into at least a second common part and a second private part; combining the first common part and the second common part to provide a common message; assigning a common group identifier to a group of devices comprising the first device and the second device; processing the common message, wherein the processing comprises scrambling the common message using the common group identifier; and transmitting the processed common message to the group of devices.

Data scrambling in rate-split communications

A method of wireless communication performed by a user equipment (UE) includes receiving a message indicating multiple control resource sets (CORESETs). Each CORESET of the multiple CORESETs comprising one or more quasi-co-location (QCL)-Type-D properties and associated with a respective physical downlink control (PDCCH) monitoring occasion of overlapping PDCCH monitoring occasions. One or more respective PDCCH candidates corresponding to the respective PDCCH monitoring occasion. The method also includes receiving, on one or more component carriers (CCs) operating on a same band, simultaneous beams comprising multiple PDCCH candidates. The method further includes monitoring a set of PDCCH candidates of the plurality of PDCCH candidates comprising a first CORESET of the multiple CORESETs comprising a first QCL-Type-D property, a second CORESET of the multiple CORESETs associated with a second QCL-Type-D property, and a set of monitoring CORESETs of the multiple CORESETs. Each of the monitoring CORESET associated with one or both of the first QCL-Type-D property or the second QCL-Type-D property based on a number of QCL-Type-D properties of a respective monitoring CORESET. In some examples, the first CORESET is a highest priority CORESET based on a set of priority rules.

Quasi co-location (QCL) prioritization rules for multi-transmission configuration indicator (TCI) state control resource set (CORESET)

Methods, systems, and devices for wireless communications are described. A user equipment (UE) may determine a first physical layer cell identifier (PCI) corresponding to a serving cell configured for the UE and a second PCI corresponding to a second cell configured for the UE different than the serving cell. Subsequently, the UE may receive at least one synchronization signal block (SSB) associated with the first PCI or the second PCI, where the SSB overlaps in time with one or more downlink channels. Accordingly, the UE may determine a quasi co-location (QCL) relationship between the SSB and the one or more downlink channels based on which PCI is associated with the SSB. In some examples, the UE may determine the QCL relationship based on a capability of the UE to receive one or two beams simultaneously.

A user equipment (UE) may receive, from a base station, a downlink configuration of a first physical uplink control channel (PUCCH) group that configures a first hybrid automatic repeat request (HARQ) feedback payload corresponding to a first semi-persistent scheduling (SPS) downlink packet for deferral and does not configure a second HARQ feedback payload corresponding to a second SPS downlink packet for deferral. The UE also may delay transmission of at least the first HARQ feedback payload based on different configurations for HARQ feedback deferral between the first SPS downlink packet and the second SPS downlink packet.

A method, a computer-readable medium, and an apparatus are provided for wireless communication including random access between a base station and a user equipment (UE). The UE transmits a beam report comprising beam measurement information to the base station and transmits a first random access message to the base station for reception using one or more beams based on a random access measurement that is different than the beam measurement information comprised in the beam report. The UE monitors for a second random access message from the base station using multiple beams, the beams being selected based on the beam report.

Wireless communications systems and methods related to communicating ACK/NACK feedbacks for multi-user and unicast physical down-link shared channel (PDSCH) communications are provided. A UE may receive a multi-user PDSCH communication including a first transport block (TB) for the UE and may receive a unicast PDSCH communication including a second TB for the UE. The UE may determine a hybrid automatic repeat request (HARQ) codebook for the first TB associated with the multi-user PDSCH communication and the second TB associated with the unicast PDSCH communication. The UE may transmit a first acknowledgement/negative-acknowledgment (ACK/NACK) feedback for the first TB and a second ACK/NACK feedback for the second TB based on the determined HARQ codebook.
