    Abstract: A user equipment (UE) is configured with multi-transmission and reception point (multi-TRP) operation. The UE groups capabilities of handling two overlapping physical downlink shared channel (PDSCH) transmissions into a plurality of groups, determining a UE capability of handling two overlapping PDSCH transmissions based on the plurality of groups and transmits the UE capability to a next generation nodeB (gNB) of a 5G new radio (NR) wireless network. The UE also determines if a demodulation reference signal (DMRS) of a physical downlink shared channel (PDSCH) transmission collides with a cell-specific reference signal (CRS) of a long term evolution (LTE) transmission and determines if the CRS originated from a same multi-transmission/reception point (TRP) as the DMRS.

    Abstract: Some embodiments include an apparatus, method, and computer program product for using low layer protocols for inter-cell mobility management in a 5G wireless communications system. A serving 5G node B (gNB) can configure reports that a user equipment (UE) transmits to the serving gNB to make handover decisions. The serving gNB can configure a group of Transmission Configuration Indication (TCI) states (e.g., a group of beams) that correspond a physical cell, and the report includes layer 3 measurements corresponding to a neighboring or serving cell's TCI state. The report can be conveyed using lower layer protocols. The report can include layer 1 measurements conveyed using a layer 1 protocol and the serving gNB can perform filtering to generate corresponding layer 3 measurement results. Based on the reports, the serving gNB can perform a handover and synchronization using lower layer protocols, from one TCI state to another.

    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: 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.
