Abstract: Various aspects of the present disclosure generally relate to wireless communication. For example, some aspects relate to techniques to signal information related to a cell discontinuous transmission (DTX) or discontinuous reception (DRX) configuration prior to a user equipment (UE) commencing a random access channel (RACH) procedure or during the RACH procedure. In this way, after the RACH procedure is complete, the UE may start to monitor physical downlink control channel (PDCCH) occasions in a next active time associated with the cell DTX/DRX configuration. Additionally or alternatively, information related to a cell DTX configuration may be signaled in a system information block (SIB) or a multicast/broadcast service (MBS) configuration for UEs receiving MBS communications. Accordingly, the UE may refrain from attempting to decode a multicast traffic channel (MTCH) and/or refrain from attempting to decode the MTCH and a multicast control channel (MCCH) during the inactive time of the cell DTX configuration.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. Some aspects relate generally to UE discontinuous reception (DRX) timing in association with a cell discontinuous transmission (DTX) configuration and/or a cell DRX configuration (“cell DTX/DRX configuration”). Some aspects more specifically relate to modifying one or more UE DRX timers in association with a cell DTX cycle and/or a cell DRX cycle (“cell DTX/DRX cycle”). For example, in some aspects, a UE may modify UE DRX timers to maintain a number of activity states in association with the cell DTX/DRX configuration. For example, the UE may maintain a UE active time, a UE DRX inactive time, a cell DTX non-active time, a cell DRX non-active time, and/or a cell DTX/DRX non-active time in association with the cell DTX/DRX configuration.

Abstract: Methods, apparatuses, and computer-readable medium for configuring a reconfigurable intelligent surface (RIS) are provided. An example method may include receiving, from a second wireless device through a RIS, a set of reference signals (RSs) mapped to a set of single port resources, the set of single port resources being quasi-co-located (QCLed) and time division multiplexed (TDMed). The example method may further include transmitting, to the second wireless device through the RIS, a set of measurement results based on the set of RSs, the set of measurement results being mapped to a set of surface configurations of the RIS.

Abstract: Methods, systems, and devices for wireless communications are described. A user equipment (UE) may receive a configuration for a transmission configuration state for receiving downlink channel transmissions from a base station via a configurable surface. The transmission configuration state may indicate a quasi-co-location source associated with transmission via the configurable surface. The UE may receive a downlink channel transmission via the configurable surface based on the transmission configuration state and the quasi-co-location source. The UE may be capable of determining whether the transmission configuration state conflicts with the quasi-co-location source indicated by the transmission configuration state. The UE may transmit an indication to the base station that the configuration for the transmission configuration state conflicts with the quasi-co-location source. The indication may include a beam failure indication or a measurement report. The UE may fall back to a transmission configuration state previously activated at the UE.

Abstract: Certain aspects of the present disclosure provide techniques for securing physical (PHY) layer communications. Certain aspects relate to a method for wireless communication by a user equipment (UE). In some examples, the method includes receiving, from a wireless communication device, an indication of a mode of a plurality of modes for use for secure communication over a physical (PHY) channel, wherein each of the plurality of modes is associated with one or more of: one or more types of signals to secure using one or more secret keys; or one or more techniques to secure communication using the one or more secret keys. In some examples, the method includes communicating over the PHY channel in accordance with the mode.

Abstract: The described techniques enable repeated physical random access channel (PRACH) preamble transmissions across multiple random access occasions (ROs) using a same spatial filter. A user equipment (UE) may transmit a PRACH preamble across multiple ROs, where each RO is associated with a same synchronization signal block (SSB) or channel state information reference signal (CSI-RS). The PRACH repetitions may be transmitted in ROs in accordance with a first mapping rule: first, in increasing order of frequency resource index; second, in increasing order of a time resource index; third, in increasing order of PRACH slot indices; and fourth, in increasing order of PRACH association period indices. Additionally, or alternatively, the PRACH repetitions may be transmitted in ROs in accordance with a second mapping rule: first, in increasing order of time resource index; second, in increasing order of PRACH slot indices; and third, in increasing order of PRACH association period indices.
