Abstract: A wireless communication system may use higher layer signaling to send transmission configuration indicator (TCI) parameters for a frequency band comprising the 52.6 GHz to 71 GHz range. A DCI message may be used to indicate an enabled TCI state for a channel occupancy time (COT). The wireless communication system may apply the enabled TCI state for the COT as indicated in the DCI message.

Abstract: Techniques are provided for Wake up signal monitoring in a radio resource control connected (RRC) mode. An example method can include a user equipment (UE) determining capability information associated with wake-up signal (WUS) monitoring, the capability information to include an indication that the UE supports WUS monitoring in a radio resource control (RRC) connected mode. The UE can transmit, to a base station, an indication of the capability. The UE can perform, while in a sleep state in which transmitting and receiving by a main radio is suspended, WUS monitoring to detect a trigger. The UE can transition from the sleep state to the awake state based on the trigger. The UE can monitor for a downlink (DL) transmission in the awake state.

Abstract: The present disclosure is related to techniques for configuring a repeater device by control signaling in a wireless communications system. In some embodiments, a repeater device is configured to form separate coverage regions. For example, the repeater device determines a first coverage region based on a first beam at the repeater device paired with a network device, wherein the first coverage region corresponds to a direction such that the first beam falls within the first coverage region for serving a control link or a backhaul link between the repeater device and the network device. Based on a first indication, the repeater device determines one or more coverage regions with respect to the first coverage region, wherein the one or more coverage regions are configured to communicate with a user equipment via an access link of the repeater device.

Abstract: Triggering an uplink (UL) gap at a base station may include decoding a user equipment (UE) UL gap capability report received from a UE. A radio resource control (RRC) UL gap configuration for transmission to the UE may be encoded. The RRC UL gap configuration may include configuration information associated with at least one of a periodicity, offset, or length. Measurement information received from the UE may be decoded. The measurement information may include at least one of a power headroom value, a PCMAX,f,c value, or a P value. Based on the power headroom value, the PCMAX,f,c value, or the P value, the UL gap configuration may be activated by encoding a medium access control (MAC) control element (MAC CE) for transmission to the UE.

Abstract: Systems and methods for utilizing inter-UE coordination regarding reserved resources of a sidelink (SL) resource pool are described herein. A first user equipment (UE) may identify that a first SL resource pool on a first radio access technology (RAT) overlaps with a second SL resource pool on a second RAT, sense for reservation signaling on the second SL resource pool to determine reserved resources on the second SL resource pool, and transmit resource reservation information indicating those reserved resources on SL on the first RAT. A second UE may receive the resource reservation information on the SL, identify, within the first SL resource pool, corresponding resources that overlap with the reserved resources of the second SL resource pool, select, from the first SL resource pool, transmission resources to use for a SL transmission by prioritizing resources other than the corresponding resources; and perform the SL transmission using those transmission resources.

Abstract: Methods and systems are disclosed to configure different paging occasions for enhanced UEs that support, and for legacy UEs that do not support, the enhanced feature of the paging early indication (PEI) in paging procedure for 5G/LTE networks. Different paging occasions for the enhanced and legacy UEs may be configured by providing separate paging occasion parameters for the enhanced and legacy UEs. The network may use the separate paging parameters to design the PEI to save signaling overhead. The network may reuse paging format for the paging PDCCH to serve as the PEI that is transmitted in advance of the paging occasions for the enhanced UEs, or may keep legacy paging PDCCH at its current locations to serve as the PEI for the enhanced UEs. A scheduling offset may be configured to separate in time the paging PDCCH serving as the PEI and the paging PDSCH containing the paging message.
