Abstract: To accommodate a mix of high frequency carriers and lower frequency carriers, a protocol stack may include a radio link control (RLC) entity that allows configuration of status reporting control parameters on per carrier, or per subcarrier spacing. Alternatively, a protocol stack may include two RLC entities, one for handling high frequency carriers, and another for handling lower frequency carriers. (High frequency carriers and lower frequency carriers may be distinguished based on a frequency threshold.) Furthermore, a user equipment may transmit (to the network) an indication of its L2 buffer size. The network may configure the UE and/or control scheduling, to ensure the UE's L2 buffer does not overrun. Alternatively, the UE may indicate that it can support a percentage of a maximum buffer size. The network may configure the UE and/or control scheduling so that the UE's buffer occupancy does not exceed the percentage.

Abstract: Systems, apparatuses, and methods for notification support in extended discontinuous reception mode. A base station and UE may configure eDRX communication. An indication may be received during the eDRX communication. The network may cache the indication. The network may modify the DRX configuration. The network may use a wake up signal. In response, the UE may receive the indication while achieving power savings from the eDRX configuration.

Abstract: Systems, methods, and circuitries are provided for direct transmission of uplink data by an INACTIVE UE using a contention free random access (CFRA) process. In one example, a method, includes, receiving uplink data from transmitted by a user equipment (UE) device while the UE is in a radio resource control (RRC) INACTIVE state, wherein the UE uses a contention-free random access (CFRA) process to transmit the uplink data using a dedicated physical random access channel (PRACH) resource or a dedicated preamble resource (dedicated PRACH/preamble resource) assigned to the UE by a network.

Abstract: Systems and methods used by reduced sensing user equipment (UE) (relative to a full sensing UE) are disclosed herein. A UE performing partial sensing may use knowledge of resource reservation periods for a resource pool of one or more resources to reduce sensing as compared to the full sensing case. A UE performing resource re-evaluation and/or resource pre-emption may use one or more sensing windows that are relatively smaller than windows used in the full sensing case to reduce sensing. A UE performing prioritized resource selection may use a sensing window to determine availability of resources within it prioritized resource selection window with a high reliability, thereby reducing the need to spend power on other sensing methods (which may include full sensing methods). Combinations of these embodiments are also contemplated.

Abstract: Systems and methods for implementing various metrics for in integrated IAB networks are disclosed. A child IAB node may determine metrics regarding one or more of its data flows and report these metrics to an upstream IAB node (that is a parent node and/or an IAB donor). The upstream node may determine a data flow prioritization configuration using these metrics that it either uses itself or sends back to the child IAB node or another IAB node of the IAB network for use there. Metrics discussed include a number of hops metric, an aggregate throughput per BH RLC channel ID (or per routing ID) metric, a fairness index per BH RLC channel ID (or per routing ID) metric, a packet drop metric, and a per-hop latency for aggregated traffic per BH RLC channel ID (or per routing ID) per IAB node metric.

Abstract: A method and apparatus of a device that acquires transmission configuration indicator (TCI) information for secondary cell (SCell) activation. In some embodiments, the TCI information is acquired for SCell activation by determining, during secondary cell (SCell) activation, that beam information to enable a user equipment (UE) to make a reliable layer 1 (L1)-Reference Signal Received Power (RSRP) measurement report is unavailable, perform the L1-RSRP measurement using information of one or more Synchronization Signal Blocks (SSBs) during the SCell activation, wherein the one or more processors perform the L1-RSRP measurement using information of one or more SSBs during the SCell activation by identifying, by the UE, one or more detectable SSBs during the SCell activation and using information of the one or more detectable SSBs for the L1-RSRP measurement.

Abstract: Techniques, described herein, include solutions for enabling power control processes within a wireless telecommunications network. A base station may operate in a full duplex mode by simultaneously sending and receiving signals to user equipment (UEs). Power control processes may be implemented to eliminate or mitigate signal interference, such as self-interference at the base station or cross link interference (CLI) at a UE. The power control processes may include causing UEs to transmit signals, a UE and/or the base station measuring interference and causing the base station and/or UEs to modify transmission power to address the signal interference.

Abstract: Apparatuses, systems, and methods for a wireless device to perform methods for configuring a power savings signal in fifth generation (5G) new radio (NR) networks. The wireless device may transmit, to a base station within a network, power savings requirements and receiving, from the base station, a configuration of a power saving signal, where the configuration indicates one or more functionalities of the power saving signal. The wireless device may periodically receive, from the base station, the power saving signal and interpret the power saving signal based on the configuration. The configuration of the power saving signal may be received via radio resource control signaling.
