Abstract: A UE may transmit a message comprising information regarding one or more physical random access channel (PRACH) capabilities of the UE to a base station (BS). The UE may then receive, from the BS, signaling comprising an indication of one or more configured PRACH formats supporting the one or more PRACH capabilities. Next, the UE may transmit, using the one or more configured PRACH formats, one or more preambles to the BS in a random access (RACH) procedure. Accordingly, the UE may receive a random access response (RAR) from the base station and further, in response to receiving the RAR, establish a connection with the BS.

Abstract: Techniques discussed herein may better ensure proper timing and synchronization of transmissions within a wireless communications network that includes a terrestrial network and a non-terrestrial network (NTN). A user equipment (UE) may maintain (e.g., determine and update on an ongoing basis) a timing advance (TA) value that the UE may apply to uplink (UL) transmissions to account for propagation delays, including changes in propagation delays, between the UE, NTN, and terrestrial network. TA maintenance may be based on network broadcasts, random access channel (RACH) procedures, control messages, timing drift rates (e.g., of the UE or NTN satellite), beam switching, and more.

Abstract: Systems and methods disclosed herein use channel state information (CSI) reports from a user equipment (UE) having additional CSI beyond CSI directly derived according to a current MIMO configuration between a base station and the UE. In some embodiments, a channel quality indicator (CQI) according to a selected layer of a plurality of layers used to receive the MIMO transmission as determined relative to the MIMO transmission is reported. In some embodiments, a precoding matrix indicator (PMI) according to a selected layer of a plurality of layers useable to receive rank 1 transmissions is reported along with a CQI determined according to that layer, or according to a layer used to receive the MIMO transmission as determined relative to the MIMO transmission. In some embodiments, a base station configures a UE to report more fulsome CSI according to each of a plurality of ranks.

Abstract: A user equipment for cross-division duplex (XDD) operations comprises circuitry configured to perform operations for determining a transmission direction for a slot of a frame structure as being an uplink (UL) slot or a downlink (DL) slot operating in XDD mode based on scheduling data from a base station. The UE is configured to receive scheduling data indicating a switching gap of the frame structure for switching from DL to UL transmission, determine that the switching gap is smaller than a threshold value to cause a collision between UL transmission and DL reception for a slot, and resolve the collision based on the UL transmission and the DL reception.

Abstract: This disclosure relates to techniques for providing an artificial intelligence based framework for performing channel state information reporting in a wireless communication system. A cellular base station may provide system information for a cell to a wireless device. The system information may indicate that the cell supports artificial intelligence based channel state information reporting. The wireless device may provide wireless device capability information to the cellular base station. The capability information may indicate that the wireless device supports artificial intelligence based channel state information reporting. The wireless device may determine an artificial intelligence model to use to perform channel state information reporting with the cell, and may perform channel state information reporting using the selected artificial intelligence model.

Abstract: An approach to communication by a user equipment (UE) in a wireless communication system that includes the UE sending an RRC setup request message including a paging offset value to a base station. The UE receives an RRC setup message from the network node, the RRC setup message including a PS-paging offset value and a PS-P-RNTI value associated with the UE. Energy conservation approaches for use with paging are described, including paging occasion monitor reporting and configuration, paging-offset reporting, the use of a paging monitoring skipping signal, and the use of dynamic TRS triggering for paging reception.

Abstract: Various systems and methods disclosed herein describe improvements for beam management that leverage virtualization across a vertical polarization (V-Pol) and horizontal polarization (H-Pol). One or more of a user equipment (UE) and a base station may include an antenna array comprising V-Pol antenna elements and H-Pol antenna elements. The UE may determine a number of receive (Rx) beam of an Rx beam sweep are needed, signal this number to the base station, and perform the beam sweep according to one or both of the V-Pol and H-Pol. A UE may use group based beam reporting to indicate to the base station a transmit (Tx) beam upon which downlink MIMO using V-Pol and H-Pol may be supported by reporting a same transmission configuration indication (TCI) corresponding to the Tx beam for both a first Rx beam and a second Rx beam in a group based beam reporting message.
