Abstract: The exemplary embodiments relate to implementing network slice aware cell selection at a user equipment (UE). This may include receiving information indicating that a cell of a network supports a network slice. The UE may identify that the UE is located within the coverage area of the cell and determine whether measurement data corresponding to the cell satisfies predetermined criteria. when the measurement data satisfies the criteria, the UE may camp on the cell.

Abstract: Systems, devices and methods for a user equipment (UE) to perform public land mobile network (PLMN) selection with a non-terrestrial network (NTN). A UE performs a non-access stratum (NAS) procedure with a public land mobile network (PLMN) of an NTN. The UE receives a NAS message from the PLMN, and the NAS message indicates that the UE is not allowed to access a core network of the NTN. The NAS message may indicate that the UE is not allowed to access the core network of the NTN because a location of the UE is unknown to the NTN, that access to the NTN is not allowed in a country in which the UE is located, or that a location of the UE is not within a country associated with the NTN. The UE modifies its PLMN search procedure responsive to receiving the NAS message.

Abstract: Methods, systems, and devices for transmitting credits in a downlink (DL) that include detecting adversity associated with the DL, e.g., network congestion, high CPU loads, thermal threshold of components, etc. In response to the adversity, a policy is determined that includes a number of ranked rules, and the policy is enabled. A baseband (BB) receives an indication of a number of available credits that may be received by an Application Processor (AP), and a number of credits equal to the number of available credits is downloaded based on the policy. The policy may include performing a first pass and a second pass of credit distribution to ensure fairness, while maintaining the respective priority levels of applications serviced in the DL.

Abstract: Disclosed are embodiments for reducing likelihood of selecting a cell identified by a Radio Access Network (RAN) Notification Area ID (RNA ID) that is different from that identifying a last or current serving cell so as to avoid an RNA update procedure; reducing Random Access Channel (RACH) transmissions for an RNA update procedure and a mobile originated (MO) data transmission in response to a Radio Resource Control (RRC) triggered RNA update procedure; and selecting a band or beam in a multi-band/beam cellular system that improves RACH efficiency.

Abstract: Systems, methods, and circuitries are provided for using an application Layer 2 buffer for reordering out of sequence (OOS) packets when possible to reduce an amount of memory allocated to a baseband (BB) Layer 2 (L2) buffer. In one example, a baseband circuitry of a user equipment (UE), includes BB memory, configured as a BB L2 buffer and one or more BB processors. The BB processors are configured to receive an OOS packet from a physical layer; and in response to an APP L2 buffer status indicating at least a first amount of memory is available, send the OOS packet to APP circuitry for storing in an APP L2 buffer.

Abstract: Methods, systems, and devices for wireless communications are described. A user equipment (UE) may receive a first authentication request in response to a first triggering request from the UE to a mobility management node of a first Tracking Area (TA) in which the UE is located. In some embodiments, the UE may prepare and store an authentication response according to the first authentication request. In response to determining that the UE has moved from the first TA to a second TA, the UE may abort a sending of the authentication response, and may send the stored authentication response according to the first authentication request to the mobility management node of the second TA in response to the receipt of the second authentication request and in further response to a determination that a given parameter of each of the first and second authentication requests are the same.
