Abstract: The exemplary embodiments relate to a user equipment (UE) delivering an indication of one or more uplink listen-before-talk (LBT) failures to a network. The UE may identify a predetermined condition corresponding to one or more uplink listen-before-talk (LBT) failures associated with a special cell (SpCell). The UE is triggered to provide an indication of uplink LBT failure associated with the SpCell to the network based on the predetermined condition. Next, the UE may determine a type of message that is to be used to deliver the indication of uplink LBT failure associated with the SpCell to the network. The UE may transmit the type of message including the indication of uplink LBT failure associated with the SpCell to the network. Subsequently, the UE may determine that the network received the indication of uplink LBT failure associated with the SpCell.

Abstract: A user equipment (UE) is connected to a wireless network and operates in a carrier aggregation (CA) state that includes a first connection to a primary cell and a second connection to a secondary cell. The UE determines a beam failure has occurred for one of the first connection or the second connection and initiates a beam failure recovery (BFR) operation. The BFR operation includes transmitting, to the primary cell, a BFR Medium Access Control (MAC) Control Element (CE).

Abstract: Techniques, described herein, include solutions for enabling a user equipment (UEs) to operate in a power saving mode (PSM) by performing radio link monitoring (RLM), beam failure detection (BFD), and radio resource management (RRM) based on one or more reference signals with a decreased periodicity. The reference signals may include system synchronizations blocks (SSBs), a channel state information (CSI) m signal (CSI-RSs), or a combination thereof. A base station may be configured to operate as a master cell group (MCG) node or a secondary cell group (SCG) node and may transmit reference signals with an increased periodicity to UEs in an active mode of operation while also transmitting reference signals with a decreased periodicity to UEs in a PSM.

Abstract: Provided is a method performed by a user equipment (UE), comprising: receiving, from a network (NW) comprising a master node (MN) and a secondary node (SN), one or more messages comprising pre-configured measurement gap (pre-MG) configurations for at least one pre-MG, wherein the UE is in dual connectivity (DC) with the MN and the SN; and determining, from the pre-MG configurations, respective pre-MG statuses for the at least one pre-MG, wherein the MN comprises a master cell group (MCG) and the SN comprises a secondary cell group (SCG).

Abstract: Methods to enhance the coverage of NR systems for coverage-limited wireless devices are disclosed. A user equipment (UE) may receive, from a base station, information indicating that a coverage enhancement mode is supported. The UE may determine whether to enter the coverage enhancement mode based on a downlink signal synchronization block (DL SSB). In response to determining to enter the coverage enhancement mode, the UE may transmit a reserved preamble to the base station to initiate random access for the coverage enhancement mode.

Abstract: This disclosure relates to techniques for supporting cell set based mobility. A network may provide configuration information to a wireless device, relating to a current cell and possibly to one or more other cells in one or more cell sets. The wireless device and network may take various measurements. In response to the measurements and the configuration information, the wireless device may perform a cell change to one of the other cells.
