Abstract: Approaches are described that enhance the reliability of physical downlink control channel (PDCCH) detection where the PDCCH can be transmitted repeatedly with different beams. The approaches use soft combining where the user equipment (UE) combines the soft bits from each repetition, with the combined soft bits used to jointly decode the PDCCH repetitions. To support the soft combining, the UE needs to buffer the soft bits. Buffering approaches include determining what contributes towards the buffering, including scenarios where one of the linked search sets (SSs) is dropped, what is contributed in a linked SS set pair, how the duration of buffer counting is determined, and how the UE reports its maximum buffer size capability. In scenarios where the required buffer size exceeds the UE maximum buffer size, a priority rule may be used in the PDCCH decoding using the SS sets pair, where the priority is based on the SS type, the serving cell index, the SS set ID and/or the control channel resource set (CORESET) ID.

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: 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: 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.

The UE receives a system information block (SIB) transmission from a base station of a wireless network, receives a downlink control information (DCI) transmission scheduling a message 2 (Msg2) transmission from the base station, receives the Msg2 transmission including an uplink (UL) grant for a message 3 (Msg3) initial transmission from the base station, determines the number of repetitions for the Msg3 initial transmission based on at least one of the SIB transmission, the DCI transmission, and the Msg2 transmission and determines a frequency hopping (FH) type and FH pattern based on at least one of the SIB transmission, the DCI transmission, and the Msg2 transmission.

Abstract: A base station can support dynamic spectrum sharing (DSS) between new radio (NR) services and Long Term Evolution (LTE) services. The base station can determine whether a NR physical downlink control channel (PDCCH) control resource set (CORESET) and a LTE PDCCH frequency range are partially overlapped in a frequency domain including a first frequency region and a second frequency region. The partial overlap occurs when the LTE PDCCH frequency range overlaps with the NR PDCCH CORESET in the first frequency region without overlapping with the NR PDCCH CORESET in the second frequency region. In response to a determination that the partial overlap occurs, the base station can map a NR PDCCH or a NR PDCCH demodulation reference signal (DMRS) to resource elements in the second frequency region, and map a LTE cell-specific reference signal (CRS) to a symbol carrying the LTE CRS in the first frequency region.

Abstract: A method that determines a resource at a first user equipment (UE) for a sidelink communication from the second UE to a first UE is described. In an exemplary embodiment, the method receives a request from the second UE to send data to the first UE. In addition, the method determines a preconfigured resource selection window that is used by the second UE. Furthermore, the method determines a first sensing result at the first UE. The determined first sensing result includes information to be reported to the second UE for a resource selection. The determined first sensing results has a plurality of first sensing types. Further, the method transmits the first sensing result from the first UE to the second UE.

Abstract: Embodiments of the present disclosure relate to discontinuous reception (DRX) transmission. Embodiments of the present disclosure propose a solution for DRX configurations for point-to-point (PTP) and/or point-to-multipoint (PTM) transmissions. In this solution, a user equipment (UE) maintains separate DRX configurations for PTP transmissions and PTM transmissions. During active time for the PTP transmissions, the UE monitors physical downlink control channel (PDCCH) with a UE specific identifier. The UE monitors PDCCH with a PTM transmission specific identifier during active time for the PTM transmissions. In this way, it can match the MBS service quality mechanism. Moreover, it also saves power at the UE.
