Abstract: Some aspects include an apparatus, method, and computer program product for radio resource management measurement prioritization for reduced capacity (RedCap) user equipment (UE). A RedCap UE may be use Half-Duplex Frequency Division Duplex (HD-FDD) for wireless communications. When performing communications with a network, the RedCap UE may make several measurements, including Reference Signal Received Power (RSRP), Signal to Interference and Noise Ratio (SINR), and Reference Signal Received Quality (RSRQ) measurements. To obtain these measurements, the RedCap UE may measure Synchronization Signal Block (SSB), Received Signal Strength Indicator (RSSI), and/or Channel State Information Reference Signal (CSI-RS) symbols. Difficulties may arise when a RedCap UE's serving cell signal timing is not synchronized with a neighboring cell. The RedCap UE may be configured to prioritize measurements over uplink transmissions. This prioritization may also include symbol buffers so that an overlap in uplink transmissions does not occur during a measurement.

Abstract: This disclosure provides details of sequence-based WUS design and signaling, also DCI-based WUS design which also serves as scheduling DCI. For sequence-based WUS there are two variants. A first is based on CSI-RS, that is relatively wide band so the sequence occupies wider band compared to SSB transmission. The second is more akin to the Secondary Synchronization Signal (SSS) type of sequence in that it occupies a narrower band over the entire bandwidth.

Abstract: A user equipment (UE) may attempt to access an edge data network. The UE generates a first credential based on a second credential that was generated for a procedure between the UE and a network. The UE then generates an identifier corresponding to the first credential and generates a message authentication code based on the first credential and a count, wherein the count is associated with an identifier of an edge network client running on the UE. The UE then transmits an application registration request, message to a server associated with an edge data network, the application registration request message including the count, the message authentication code, the identifier corresponding to the first credential, and a public land mobile network identifier (PLMN ID) of the network. The UE then receives an authentication accept message or an authentication reject message from the server associated with the edge data network.

Abstract: Embodiments of the present disclosure relate to methods, a terminal device, a network device, and computer program products for SCell management in wireless communication. A terminal device receives from a network device configuration information for configuring a triggering mode. The triggering mode is for triggering activation of a secondary cell of the terminal device and a transmission of a temporary reference signal in the secondary cell. Based on the configured triggering mode, the terminal device receives first triggering information on the activation of the secondary cell and second triggering information on the transmission of the temporary reference signal for performing the activation of the secondary cell. In this way, it is possible to reduce the latency of activation/de-activation procedure for SCG and secondary cells.

Abstract: Embodiments of the present disclosure relate to downlink data reception operation. According to embodiments of the present disclosure, a baseband processor of a user equipment (UE) is configured to perform operations comprising receiving Downlink Control Information (DCI) through more than one beams from at least one from at least one TRP; determining a DCI transmission scheme for the received DCI, wherein the DCI transmission scheme is configured by an upper layer signaling, and wherein the DCI transmission scheme is one of a Single Frequency Network (SFN) scheme, a non-SFN scheme, and a hybrid scheme, wherein the DCI is transmitted using both SFN scheme and non-SFH scheme in the hybrid scheme; determining whether the received DCI indicates a Transmission Configuration Indicator (TCI) for PDSCH reception from the at least one TRP or not. The operations further comprise in accordance with a determination that the received DCI fails to indicate the TCI and based on the determined DCI transmission scheme, selecting at least one TCI for the PDSCH reception from candidate TCIs configured for one or more Control Resource Sets (CORESETs) associated with the DCI.
