Abstract: A method and apparatus for a reflective intelligent surface (RIS) control interface. The apparatus transmits, to a RIS, a synchronization signal to establish a level of synchronization between the base station and the RIS. The level of synchronization between the base station and the RIS configures the RIS to receive a control signal from the base station. The apparatus transmits, to the RIS, the control signal comprising a RIS configuration. The apparatus may transmit, to the RIS, a signal for reflection by the RIS to at least a first wireless device.

Abstract: Certain aspects of the present disclosure provide techniques for randomization of reconfigurable intelligent surface (RIS) signals. A method for wireless communication includes determining a random reflection parameter for each of one or more RISs. The random reflection parameter is random over time for the one or more RISs. The method includes applying random values of the random reflection parameter at different times at each of the one or more RISs.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may receive a message indicating that the UE is to execute a make-before-break handover procedure. The UE may transmit, during the make-before-break handover procedure and based at least in part on a prioritization rule, a first uplink communication to a target base station. The prioritization rule may indicate a relative priority for different uplink communications included in a group of uplink communications. The group of uplink communications may include at least the first uplink communication to be transmitted by the UE to the target base station and a second uplink communication to be transmitted by the UE to a source base station during the make-before-break handover procedure. Numerous other aspects are described.

Abstract: A UE may identify a UE mobility condition associated with cell coverage switching. The UE may perform a measurement procedure based on the UE mobility condition associated with the cell coverage switching. The UE mobility condition associated with the cell coverage switching may be identified based on a count of consecutive cell reselections. The UE mobility condition associated with the cell coverage switching may be identified further based on a cell coverage region associated with the cell coverage switching or further based on a UE measurement. The measurement procedure may or may not include a relaxed measurement procedure. The measurement procedure may be performed based further on at least one criterion associated with the cell coverage switching. The UE may receive an indication of the at least one criterion associated with the cell coverage switching from a network node.

Abstract: Methods, systems, and devices for wireless communication are described. A communication device, such as a user equipment (UE) may receive a configuration (for example, via control signaling) of a set of reconfigurable intelligent surfaces (RISs). The UE may select a primary RIS for bidirectional wireless communication (for example, uplink and downlink) and one or more secondary RISs for unidirectional wireless communication (for example, downlink) based on the configuration. The UE may use the one or more secondary RISs to enable higher throughput and extended coverage in the wireless communication system, for example, for downlink. The UE may communicate with the base station using the primary RIS, or the secondary RIS, or both.

Abstract: A method for wireless communication at a user equipment (UE), includes receiving, from any one transmit and receive point (TRP) of a group of TRPs, a first radio resource control (RRC) message configuring a linkage between a first physical downlink control channel (PDCCH) candidate associated with a first monitoring occasion in a first search space (SS) set associated with a first TRP of the group of TRPs and a second PDCCH candidate associated with a second monitoring occasion in a second SS set associated with a second TRP of the group of TRPs. The method also includes receiving, from any one TRP of the group of TRPs, a dynamic indication enabling or disabling the linkage. The method further includes monitoring the first monitoring occasion for first PDCCH candidate and selectively monitoring the second monitoring occasion for the second PDCCH candidate based on whether the linkage is enabled or disabled.

Abstract: Aspects are provided that allow a UE to perform DMRS bundling in different transport blocks of uplink data on PUSCH in response to a configuration from a base station indicating or enabling the UE to perform the DMRS bundling. The UE receives a configuration from a base station indicating to bundle DMRS in different uplink data channel transmissions for joint channel estimation. The UE determines a DMRS bundling window based on the configuration. The UE transmits the bundled DMRS in the DMRS bundling window. The base station performs the joint channel estimation based on the bundled DMRS. Improved link quality between the UE and base station and signal gains may accordingly result from applying DMRS bundling over different PUSCH transmissions.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may establish inter-band carrier aggregation with a synchronization signal block (SSB) anchor carrier and an SSB-less carrier. The UE may measure a synchronization signal (SS) reference signal received quality (RSRQ) of the SSB-less carrier based on a ratio of a quantity of resource blocks multiplied by an SS reference signal received power (RSRP) and divided by a New Radio (NR) received signal strength indicator (RSSI), where the SS-RSRP is measured based on an SSB on the anchor carrier. Numerous other aspects are described.
