Abstract: A user equipment (UE), a baseband processor or other network device can operate in a new radio (NR) unlicensed network can operate to communicate in a UE to UE (U2U) relay path through a first relay UE with another UE as a source or destination UE according to a direct communication request initiating from the source UE. The UE, as a source UE, can also perform the U2U relay reselection based on a measurement report received from a destination UE.

Abstract: Techniques are disclosed relating to reporting channel state information (CSI) when synchronization state is altered. In some embodiments, a UE starts a timing alignment timer (TAT) in response to a time alignment command (TAC) from a cellular network for one or more serving cells. In some embodiments, the UE stores a configuration for a semi-persistent (SP) channel state information (CSI) report for the apparatus over a physical uplink shared channel (PUSCH). In some embodiments, the UE activates the SP-CSI report based on downlink control information (DCI) from the network. In some embodiments, the UE transmits one or more SP-CSI reports according to the configuration. In some embodiments, in response to expiration of the TAT, the UE deactivates all active stored configurations of SP-CSI reports that use the PUSCH and that correspond to the one or more serving cells. In some embodiments, this may avoid collisions with PUSCH transmissions from other UEs, e.g., when the UE returns to an in-sync state.

Abstract: A base station may be configured to perform operations related to link management for a remote user equipment (UE). The operations comprising, transmitting configuration information to the remote UE and receiving information corresponding to a serving link associated with the remote UE. The operations further comprising determining that the serving link associated with the remote UE is to be switched from a first communication link to a second communication link. The operations further comprising, transmitting a message to the remote UE indicating that the serving link associated with the remote UE is to be switched from the first communication link to the second communication link. The operations further comprising, transmitting a message to a relay UE. The message is configured to trigger the relay UE to perform an operation corresponding to the serving link associated with the remote UE.

Abstract: Techniques discussed herein can facilitate transmission and reference signals (RS) associated with layer-1 (L1) operations outside of a configured carrier bandwidth (CBW) of a user equipment (UE). One example aspect is a UE with one or more processors configured to transmit UE capability information. The UE capability information includes a frequency separation threshold, where the frequency separation threshold represents a frequency separation from a CBW of the UE. The one or more processors are further configured to receive a RS within the frequency separation threshold and outside of the CBW, and subsequently perform a L1 operation based on the RS.

Abstract: Apparatuses, systems, and methods for a user equipment device (UE) to determine a default beam for a dedicated PUCCH/SRS in a CC. The UE may determine a pathloss RS has been configured in the CC, e.g., responsive to the UE determining that spatial relationship information for a default transmission beam has not been configured and determine the default beam for transmissions based, at least in part, on the (configured) pathloss RS. Additionally, responsive to determining that the pathloss RS has not been configured in the CC, the UE may determine that no CORESETs/TCI states for a PDSCH in the CC have been configured and determine the default beam for transmissions based, at least in part, on a default transmission beam in another CC, a CC index, a PRACH procedure; a PUSCH transmission; an SRS transmission, and/or a PUCCH transmission.

Abstract: Methods and systems are disclosed for a UE of a wireless communication network to recover from MCG radio link failures in a MR-DC system when the SCG is deactivated or otherwise not enabled. When a MCG link failure is detected and the SCG is deactivated, the UE may activate the SCG for the UE to use the SCG link to transmit and receive signaling messages or data as part of the MCG failure recovery procedure. When the MCG link failure is detected and the UE is configured to add the SCG upon the satisfaction of certain condition, but the condition has not occurred, the UE may check to determine whether one condition is MCG failure and whether the radio link quality of the SCG exceeds a threshold. If the radio link quality of the SCG exceeds the threshold, the UE may apply the SCG configuration to add the SCG.

Abstract: A base station is configured to transmit wake-up signals to a user equipment to wake-up the UE to receive a page from the base station. The base station transmits one or more synchronization signals, wherein the synchronization signals correspond to a wake-up signal (WUS) that is to be transmitted to a user equipment (UE) operating in a paging discontinuous reception (DRX) cycle, wherein the paging DRX cycle includes a paging occasion (PO) and transmits the WUS to the UE during a WUS occasion, wherein the WUS indicates whether the UE is to utilize an active mode or a sleep mode during the PO.
