Abstract: Methods, systems, and devices for wireless communications are described. A set of uplink control channel resources that are configured for acknowledgment transmissions may be shared among user equipments (UEs) that are enabled to receive multicast communications. Each of the shared set of uplink control channel resources may be associated with set(s) of channel state information. UEs may measure a multicast channel to determine channel state information for the multicast channel. After failing to receive a multicast transmission, UEs may transmit an acknowledgment feedback message over one of the shared uplink control channel resources that is associated with the set of channel state information determined by the UE. A base station that receives the acknowledgment feedback message may transmit a multicast retransmission for the UEs using transmission parameters that are adapted for the set(s) of channel state information associated with the occupied uplink control channel resource.

Abstract: Methods, systems, and devices for wireless communication are described. Some wireless communications systems may support a determination of user equipment (UE) capabilities, such as a category or a coverage level for broadcast or multicast content. In some cases, a radio interface may be configured to account for an indicated capability of a target UE. For example, a base station may receive an indication of a capability of a particular targeted UE. The capability of the targeted UE may be specified by a service provider to deliver multicast or broadcast content, and subsequently associated with a radio interface between the base station and the target UE. The radio interface may then be configured based on the indicated capability of the target UE, for example, by configuring a transport block size or bandwidth. The base station may then transmit broadcast or multicast content to the UE using the configured radio interface.

Abstract: In order to improve efficiency in releasing a connection with a user equipment, a method, apparatus, and computer-readable medium are presented herein. A RAN receives release assistance information from a user equipment or a User Plane Function (UPF) involved in an active session with the user equipment. The release assistance information may be received over a control plane or over a user plane. The release assistance information may be received from the user equipment or the UPF over the user plane or as Radio Resource Control (RRC) signaling. The release assistance information may be received from an application function via the UPF. The RAN determines to release the user equipment based on the release assistance information.

Abstract: Certain aspects of the present disclosure relate to methods and apparatus for handling mobility between areas with heterogeneous network slices in wireless communications systems operating according to new radio (NR) technologies. An exemplary method that may be performed by a UE includes receiving an indication that a network slice is not available, entering a connection management idle (CM-IDLE) state, and initiating a registration procedure with an access and mobility management function (AMF) subsequent to entering the CM-IDLE state.

Abstract: A method, an apparatus, and/or a computer program product for wireless communication are provided. Radio capability signaling (RACS) optimization for the radio access technology (RAT) may be deployed for some user equipments (UEs) in a network to reduce a signaling overhead associated with identifying UE radio capabilities. The UEs may be configured with a set of UE radio capability identifiers, such as a UE radio capability identifier for a narrowband (NB) RAT, a UE radio capability identifier for a non-NB RAT, and/or the like. A UE may provide a single UE radio capability identifier corresponding to a type of RAT to which the UE is to connect. The BS may determine that the UE supports RACS optimization for the RAT. If the UE does not provide the UE radio capability identifier, the BS may infer that the UE does not support RACS optimization.

Abstract: This disclosure provides systems, methods, and apparatus, including computer programs encoded on computer-readable media, for a service-based cell reselection by a user equipment (UE) in a wireless communication system. The UE may have a service relationship with a particular service. A wireless communication system may provide different types of services via different radio frequencies. The UE may determine which cells to measure for cell reselection to include those that correspond to a service of interest to the UE. In addition to power savings, the UE may experience faster cell reselection for a service. The techniques of this disclosure also may enable a priority-based cell reselection so that the UE can camp on a cell that supports a higher priority service compared to other services supported by the UE.

Abstract: Methods, systems, and devices for wireless communication are described. A user equipment (UE) may truncate or remove a number of bits from its UE identity based on identity truncating information to generate a truncated UE identity. The truncated UE identity can be transmitted by eMTC devices to a base station in an RRC connection request, and can be used by the base station to determine which core network entity stores the UE's capabilities. In some implementations, the UE may truncate or remove a number of bits from the 48-bit 5G-S-TMSI based on the identity truncating information to generate a 40-bit truncated 5G-S-TMSI that can be transmitted by an eMTC device to the base station in the RRC connection request and yet still provide the base station with enough information to determine which AMF stores the UE context.

Abstract: Methods, systems, and devices for wireless communications are described. Generally, the described techniques provide for a user equipment (UE) to determine a time gap between receiving a paging early indication (PEI) and receiving a paging message based on a link quality of the UE. The UE may determine the time gap based on a number of reference signals the UE may measure after receiving the PEI to obtain channel information for accurately decoding a forthcoming paging message and a periodicity of the reference signals. The UE may transmit UE assistance information (UAI) to the base station during an active state to indicate the time gap. The UE may receive a configuration message from the base station indicating a configured time gap for the UE based on the UAI. The UE may receive the PEI and monitor a paging occasion for the paging message according to the configured time gap.

Abstract: Wireless communications systems and methods related to mobility with consideration for network slicing are provided. In one embodiment, a user equipment (UE) transmits in a first cell frequency of a network, a request for a network slice of the network that is not provided by the first cell frequency. The UE receives, in response to the request, an information for communicating in a second cell frequency of the network that provides the requested network slice. In one embodiment, a core network entity receives, from a network entity operating over a first cell frequency of a network, a request to provide a network slice of the network to a UE, the network slice not provided by the first cell frequency. The core network entity transmits, to the BS, information associated with a second cell frequency of the network providing the network slice.

Abstract: Methods, systems, and devices for wireless communications are described. A wireless communications system may support multicast transmissions from a base station to multiple user equipments (UEs). Each UE may have uplink resources allocated for providing feedback to the base station regarding multicast transmissions. For example, a UE may not successfully decode one or more frames of a multicast transmission. When a UE does not successfully decode the one or more frames, the UE may transmit negative acknowledgment (NACK) feedback indicating the one or more frames that were not successfully received. A serving base station may store frames within a buffer for a transmission window and retransmit each of the frames indicated within the NACK feedback from the stored frames. In some cases, the serving base station may not retransmit frames that were not indicated within the NACK feedback (e.g., frames that may have been received successfully by the UE).
