Abstract: Aspects are described for a user equipment (UE) comprising a low power wake up radio (LP-WUR) and a main radio configured to enable wireless communications with a base station, and a processor communicatively coupled to the LP-WUR and the main radio. The processor is configured to receive a first low power wake up signal (LP-WUS) from the base station; determine that the first LP-WUS corresponds to a cell of the UE; and determine that the first LP-WUS indicates powering on the main radio. The processor is further configured to turn on the main radio and receive a paging message from the base station.

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: Methods and systems are disclosed for a UE to perform measurements of measurement resources transmitted by a network when the UE is configured with multiple concurrent measurement gap patterns (MGPs). The measurement resources may be carried on multiple carrier frequencies. The UE may receive measurement resource configuration parameters identifying time and frequency locations of the measurement resources transmitted on the multiple carrier frequencies. The UE may receive measurement gap configuration parameters for multiple concurrent MGPs specifying measurement intervals that may be used to perform the measurements. The UE may determine a linkage between the measurement resources on a carrier frequency and one of the concurrent MGPs so that the UE may independently measure the measurement resources received on the multiple carrier frequencies using their respectively linked MGPs. The linkage may be made through information elements in the measurement resource configuration parameters or the measurement gap configuration parameters containing the MGP.

Abstract: Inter-cell mobility may include decoding a first radio resource control (RRC) reconfiguration message received from a first cell. The first RRC reconfiguration message may comprise a first portion of configuration information for performing a cell change to a second cell. A cell change message received from the first cell may be decoded. The cell change message may indicate that a cell change to the second cell is to be performed. A cell change acknowledgment may be encoded for transmission to the second cell. A second RRC reconfiguration message received from the second cell may be decoded. The second RRC reconfiguration message may comprise a second portion of configuration information for performing the cell change to the second cell. The second portion of configuration information may comprise a remaining portion of configuration information to perform the cell change to the second cell.

Abstract: The present application relates to devices and components including apparatus, systems, and methods to perform a switch of a TCI state from a serving cell to a neighbor cell. A UE determines whether the state of the neighbor cell is known or unknown and whether the neighbor cell’s TCI state is known or unknown. The total delay time to perform the TCI state switch can impacted by this the known/unknown statuses. Other factors can also contribute to the total delay time. The UE may also signal its capability to monitor the TCI state of the neighbor cell and its capability to switch to such a TCI state.

Abstract: Methods and apparatus provide for a wireless network to enable multiple-transmission reception point (multi-TRP) uplink (UL) time division multiplexed (TDMed) repetition transmission. The network may receive, from a user equipment (UE), beam measurements of downlink reference signals associated with a plurality of UL transmission beams from the UE to the multi-TRP. Based on criteria associated with the beam measurements received from the UE, the network enables the UE for the multi-TRP UL TDMed repetition transmission using the plurality of UL transmission beams. In addition, or in other scenarios, coordination is provided between the network and the UE to improve UL TDMed repetition transmissions when a UE switches between antenna panels.
