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) monitors for a synchronization signal block (SSB) to synchronize with a cell of a network. The UE monitors a frequency band during a discovery reference signal (DRS) window for a synchronization signal block (SSB) transmitted by a cell of the network, determines an SSB index based on information received from the cell of the network and synchronizes with the cell based on the SSB index.

Abstract: A user equipment may use a soft acknowledgment/negative-acknowledgement (ACK/NACK) report to indicate a number of desired repetitions for Physical Downlink Shared Channel (PDSCH). In some embodiments, the user equipment may generate a soft ACK/NACK report that includes multiple bits. The multiple bits may be coded to indicate to a network node whether an allocated number of repetitions was sufficient, redundant or insufficient, and how many more repetitions are needed or desire by the UE.

Abstract: A cell performs simultaneous scheduling for a group of user equipment (UE). The cell associates a radio network temporary identifier (RNTI) with a group of user equipment (UEs), transmits a signal to the group of UEs, the signal scrambled by the RNTI and including control information and performs an operation indicated in the control information.

Abstract: A wake up signal scheme between a network and a user equipment (UE) operating in a Discontinuous Reception (DRX) state. The UE monitors a wake up signal (WUS) occasion to determine whether a WUS is received during the WUS occasion, when the WUS is received, determines whether the WUS identifies the UE, when the WUS is received and identifies the UE, monitors an OnDuration of a Discontinuous Reception (DRX) cycle corresponding to the WUS and when the WUS is not received or the WUS does not identify the UE, remains in a sleep state during the OnDuration corresponding to the WUS.

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: A base station includes a transceiver and a processor. The processor is configured to transmit a first synchronization signal block (SSB) burst including a first set of SSBs. The first set of SSBs is transmitted via the transceiver on a first set of beams having a first beam pattern. The processor is also configured to signal, via the transceiver, a change in beam pattern for transmitted SSBs. The change in beam pattern is signaled before or during transmission of a second SSB burst. The processor is further configured to transmit the second SSB burst. The second SSB burst includes a second set of SSBs transmitted via the transceiver on a second set of beams having a second beam pattern. The second set of beams has a different number of beams than the first set of beams, and the second set of SSBs has a different number of SSBs than the first set of SSBs.

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.
