Abstract: A communication system may include a base station (BS), user equipment (UE), and a set of reconfigurable intelligent surfaces (RIS's). The RIS's, the UE, and the BS may communicate using a control RAT and a data RAT. The BS may transmit downlink (DL) signals to the UE device via reflection off a DL RIS. The UE device may transmit uplink (UL) signals to the BS via reflection off a UL RIS. This may optimize wireless performance in situations where reflecting the UL and DL signals off the same RIS would limit performance under the current data RAT channel conditions. The BS and the UE device may use channel measurements of the control RAT at the RIS's to select the UL RIS and the DL RIS. This may significantly reduce overhead required to identify the UL and DL RIS's relative to scenarios where exhaustive beam training is used.

Abstract: Techniques are provided for Wake up signal monitoring in a radio resource control connected (RRC) mode. An example method can include a base station receiving an indication from a user equipment (UE) of a capability for wake-up signal (WUS) monitoring in a radio resource control (RRC) connected mode while in a sleep state. The base station can configure the UE with a first frequency domain resource for WUS monitoring in the RRC connected mode while in the sleep state. The base station can transmit a WUS using the first frequency domain resource and a first time domain resource, wherein a main radio of the UE is configured to transmit and receive based on the WUS. The base station can transmit a first downlink (DL) transmission.

Abstract: Apparatus and methods are provided for CSI enhancement for multi-TRP coherent joint transmission. A user equipment (UE) receives signals from a plurality of transmission and reception points (TRPs). The UE determines, based on the signals, multiple TRP (multi-TRP) coherent joint transmission (CJT) channel state information (CSI) report information for a codebook based on a spatial basis selection matrix, a combination coefficient matrix, and a frequency basis selection matrix. The spatial basis selection matrix is layer common, polarization common, and TRP independent. The UE reports, to one or more of the plurality of TRPs, the multi-TRP CJT CSI report information.

Abstract: This disclosure relates to techniques for performing multi-transmission and reception point operation in a wireless communication system. A plurality of transmission control indication states may be indicated for future use, e.g., using one or more lists. A subset of the indicated states may be activated and the subset may be greater than 8 states. One or more states of the subset may be used for performing multi-transmission and reception point operation in a single downlink control information mode.

Abstract: This application relates to wireless communications, including methods and apparatus to manage uplink (UL) transmit switching with multiple timing advance groups (TAGs) for wireless devices. A wireless device is configured to use multiple carriers selected from a set of available carriers that can be associated with different TAGs. When a second set of carriers, used after switching from a first set of carriers, includes carriers that belong to different TAGs, the wireless device determines whether to transmit on one or more first uplink transmission occasions for each of the carriers in the second set of carriers based on whether a first UL transmission occasion for at least one carrier overlaps a switching gap time period. The wireless device can disallow transmission on first UL transmission occasions of one or more carriers to accommodate the overlap.

Abstract: Techniques for a wireless device to share a Channel Occupancy Time (COT) in a sidelink (SL) channel are disclosed. The techniques include a method for sharing a Channel Occupancy Time (COT) in a sidelink (SL) channel that includes performing a Clear Channel Assessment (CCA) by a first wireless device to initialize the COT. The first wireless device determines that a portion of the COT may be shared, and transmits to one or more qualifying wireless devices, first Sidelink Control Information (SCI). The first SCI may include a destination identification (ID), an offset, and a SL duration. The destination ID indicates one or more qualifying wireless devices that may share the COT, and the SL duration defines a duration of time available for the one or more qualifying wireless devices to share the COT. The first wireless device may resume transmission in the COT.
