Abstract: A user equipment (UE) configured to connect to a network and operate in a carrier aggregation mode and a single carrier mode performs methods to select optimal component carriers. The methods include determining that a primary component carrier is operating less optimally than a secondary component carrier, sending an indication to the network that the primary component carrier is operating less optimally than the secondary component carrier, acquiring the secondary component carrier as a target primary component carrier and operating with the secondary component carrier as the target primary carrier component. In one exemplary embodiment, the indication is declaring a radio link failure (“RLF”) between the UE and the network. In another exemplary embodiment, the indication is a measurement report send to the network that triggers a handover procedure for the UE.

Abstract: QoS based uplink data buffering while TTI bundling is enabled by a wireless user equipment (UE) device. The UE may establish a packet-switched connection with a network via a wireless link. The UE may receive, at a media access control (MAC) layer, an indication to enable TTI bundling. The UE may selectively buffer uplink data at an application layer based on the indication to enable TTI bundling. The uplink data may be buffered selectively based on Quality of Service (QoS) considerations. Uplink transmissions may subsequently be performed using TTI bundling.

Abstract: Techniques, described herein, include solutions for managing hybrid automatic repeat request (HARQ) processes and communications for non-terrestrial networks (NTNs) (e.g., a wireless communication network that includes a satellite network component). A user equipment (UE) may receive a request for capability information of the UE and in response, transmit a message indicating the capability information of the UE, wherein the capability information includes HARQ disablement information indicating whether the UE supports disabled HARQ feedback.

Abstract: A base station that determines a slot for uplink reception for a non-terrestrial network link between a base station and a user equipment is described. In exemplary embodiments, the base station determines a timing advance based on at least a random access preamble reception and determines an uplink offset based on the timing advance. The base station may further determine a candidate slot for an uplink reception based on at least the offset. In addition, the base station may determine if the candidate slot is available for the uplink reception. The base station may use the candidate slot for the uplink reception when the candidate uplink slot is available and may use the next available slot for the uplink reception when the candidate uplink slot is not available.

Abstract: An application layer in a device, a service data adaptation protocol (SDAP) layer in the device, and/or a media access control (MAC) layer in the device may determine that wireless communication resources allocated to the device need to be adjusted. The determination may be in response to detecting that a quality of the wireless connection of the device has deteriorated, or it may be based on advance knowledge of information pertaining to an application layer payload in the device. In response to the determination the device may transmit, in a MAC Control Element (MAC CE) to a base station, a request for an adjustment of the allocated wireless communication resources. The adjustment may lead to a temporary boost of resources for a limited period of time or to a persistent update of the allocated wireless communication resources. To allow better scheduling of multiple QoS flows mapped to the same DRB and better selection of data when constructing a MAC Packet Data Unit (PDU), a mapping between QoS flows and LCHs may also be provided to the MAC layer.

Abstract: A first next generation Node B (gNB) is configured to establish a first backhaul communication link with a second gNB as a parent gNB, schedule at least one of a third gNB or a UE for a UL transmission to the first gNB using UL beam management parameters and UL transmission parameters, indicate to the second gNB first beam management parameters for the second gNB to use for transmitting a DL transmission to the first gNB on the first backhaul link and first DL transmission parameters for the DL transmission so that the DL transmission will be received simultaneously with the UL transmission and when the first beam management parameters and the first DL transmission parameters are determined to be used by the second gNB, receiving the DL transmission from the second gNB simultaneously with the UL transmission from the at least one of the third gNB or the UE.

Abstract: The functions of user equipment (UE), radio access network (RAN) devices, and core network (CN) devices in circumstances where a UE is expected to experience discontinuous coverage are described herein. A UE may send a CN a non-access stratum (NAS) message including a release request indicating that a UE is leaving coverage and assistance information. The CN may interrupt paging of the UE and resume the paging according to the assistance information. A UE may enter a low power usage mode upon leaving coverage, and may use one or more timers to determine when to check for coverage and send a mobility update message corresponding to the low power usage mode. A base station may receive, from a UE, a radio resource control (RRC) message comprising a release request and assistance information, send an RRC release message to the UE in response, and forward the assistance information to the CN.

Abstract: An approach is described for a base station to generate a first message and a second message. The base station transmits the first message and the second message to a user equipment (UE). The first message is associated with a cell supported by the base station and includes a first public land mobile network (PLMN) identity index and a first list of one or more network slices supported by a first PLMN associated with the first PLMN identity index. The second message is associated with one or more neighboring cells, and includes the first PLMN identity index and a second list of one or more network slice data associated the first PLMN as supported by the one or more neighboring cells. In addition, at least one of the one or more network slice data in the second list includes a sub-list of one or more neighboring cell data.

Abstract: Apparatuses, systems, and methods for non-small data transmission (non-SDT) dedicated radio bearer (DRB) handling while in a radio resource control (RRC) inactive state. A wireless device may determine, while operating in the RRC inactive state, that non-SDT data is available for transmission on a non-SDT DRB and determine, based on one or more conditions, to transmit, to a base station, non-SDT data arrival information during an SDT procedure. The one or more conditions may be associated with arrival time of the non-SDT data and/or an amount of non-SDT data to be transmitted. The arrival time may be relative to arrival of SDT data, initiation of an SDT procedure, and/or initiation of a subsequent transmission period of an SDT procedure.
