Abstract: In an aspect of the disclosure, a method, a computer-readable medium, and an apparatus are provided. The apparatus may be a UE. The UE receives, through a non-physical layer signaling, a configuration indicating to receive a first reference signal in a set of OFDM symbols in a first slot. The UE attempts to detect a physical layer signaling in the first slot or in a second slot prior to the first slot. The UE refrains from conducting measurements of the first reference signal, when the physical layer signaling is detected by the UE and includes a first indication.

Abstract: In an aspect of the disclosure, a method, a computer-readable medium, and an apparatus are provided. The apparatus may be a UE. The UE determines that a random access event has occurred. The UE detects one or more down-link reference signals that are UE-specifically configured or predefined. The UE further selects a first message that is associated with a first down-link reference signal of the one or more down-link reference signals, the first down-link reference signal being quasi-colocated with a first DMRS of a serving control channel of the UE. The UE sends the first message to a base station to request a random access to the base station.

Abstract: Various solutions for capability reporting to support small data transmission (SDT) on a bandwidth part (BWP) for user equipment (UE) are described. An apparatus may transmit UE capability information to a wireless node of a wireless network. The UE capability information may indicate that the apparatus supports using a BWP with a condition of synchronization signal block (SSB) association for SDT. The apparatus may also receive a configuration associated with the BWP for SDT from the wireless node. The configuration may be configured based on the UE capability information. The apparatus may further initiate an SDT procedure on the BWP according to the configuration.

Abstract: A method for UE capability signaling to support enhancements on resource allocation for Physical Downlink Control Channel (PDCCH) candidate monitoring in NR-U is proposed. A UE transfers UE capability information to a mobile communication network. The UE capability information includes information indicating whether the UE supports Control Resource Set (CORESET) configuration with a Resource Block (RB) offset. The UE receives resource allocation configuration of an unlicensed cell from the mobile communication network. The UE monitors PDCCH candidates on the unlicensed cell according to the resource allocation configuration.

Abstract: A method for UE capability signaling to support NR-U is proposed. A UE transfers UE capability information to a mobile communication network, and the UE capability information includes information regarding whether the UE supports system information acquisition on an unlicensed cell. The UE receives configuration from a serving cell of the mobile communication network, and the configuration includes information for system information acquisition of one or more unlicensed cells on a frequency. The UE acquires system information of the one or more unlicensed cells on the frequency and reports the acquired system information to the serving cell, or stores the acquired system information in the UE.

Abstract: In an aspect of the disclosure, a method, a computer-readable medium, and an apparatus are provided. The apparatus may be a UE. The UE receives, from a base station, one or more downlink reference signals on an unlicensed carrier. The UE determines that the base station occupies the unlicensed carrier for a predetermined first channel occupancy time based on the one or more downlink reference signals. The UE receives, on the unlicensed carrier and in the predetermined first channel occupancy time, a control burst including a plurality of down link control channels. The UE attempts to decode a first down link control channel directed to the UE from the control burst.

Abstract: Various novel concepts and schemes pertaining to non-orthogonal multiple access for wireless communications are described. A group orthogonal coded access (GOCA) scheme is introduced to reduce multi-user interference (MUI) and improve performance. A repetition division multiple access (RDMA) scheme is introduced to differentiate user equipment (UEs) by different repetition patterns. A low-density spreading (LDS) scheme is introduced to reduce MUI and improve performance.

Abstract: A method of beam failure recovery request (BFRQ) transmission is proposed. UE can search for UE-specific control channel in a search space that is signaled specifically for monitoring network response of the BFRQ. Furthermore, configurations indicated specifically for BFRQ can be carried by dedicated signaling such as high-layer radio resource control (RRC) signaling. After successfully rebuilding connection, UE assumes the demodulation reference signal (DMRS) ports of UE-specific control channel to be spatially quasi-co-located (QCL-ed) with the reference signals identified during the beam failure recovery procedure.

Abstract: A User Equipment (UE) including a wireless transceiver and a controller is provided. The wireless transceiver performs wireless transmission and reception to and from a service network. The controller initiates a random access procedure with the service network by controlling the wireless transceiver to perform wireless transmission using at least one of: a random access preamble configured for System Information (SI) request, and a corresponding Physical Random Access Channel (PRACH) time-frequency resource allocated for the random access preamble. Also, the controller receives a random access response, which includes a Random Access Preamble Identifier (RAPID) only and does not include a Timing Advance (TA) command, an uplink grant, and a temporary Cell Radio Network Temporary Identifier (C-RNTI), from the service network via the wireless transceiver.
