Abstract: A base station is configured to transmit wake-up signals to a user equipment to wake-up the UE to receive a page from the base station. The base station transmits one or more synchronization signals, wherein the synchronization signals correspond to a wake-up signal (WUS) that is to be transmitted to a user equipment (UE) operating in a paging discontinuous reception (DRX) cycle, wherein the paging DRX cycle includes a paging occasion (PO) and transmits the WUS to the UE during a WUS occasion, wherein the WUS indicates whether the UE is to utilize an active mode or a sleep mode during the PO.

Abstract: Some embodiments include an apparatus, method, and computer program product for tracking reference signal (TRS) support of high speed use cases of 5G communications in a single frequency network (SFN), where a user equipment (UE) can measure a Doppler offset of a combined signal from two or more transmission reception points (TRPs) of the 5G communications system. A 5G node B (gNB) node can transmit a periodic, semi-persistent (SP), or aperiodic TRS with high measurement density that the UE uses to measure a Doppler offset of a combined signal. For example, the gNB can: trigger the aperiodic TRS based on a downlink assignment; and/or use lower layer signaling to arrange to transmit a semi-persistent TRS or a periodic TRS with a reduced periodicity. In some embodiments, the gNB can measure the Doppler offset based on an uplink signal, and transmit a TRS based on a pre-compensated Doppler frequency.

Abstract: Various user equipment (UE) operations performed when the UE is in multiple Downlink Control Information (multi-DCI) based multiple transmission and reception point (multi-TRP) configuration. The operations receiving, from one of the first or second gNBs, one or more cell reference signal (CRS) rate matching patterns, wherein the one or more CRS rate matching patterns comprise an indication of a control resource set (CORESET) pool for each of the one or more CRS rate matching patterns and applying the one or more CRS rate matching patterns to a CORESET for a Physical Downlink Shared Channel (PDSCH) based on the indication of the CORESET pool.

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: 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: Embodiments of the present disclosure relate to aperiodic sounding reference signal (SRS) transmission. According to embodiments of the present disclosure, the collision of the triggered SRS resource sets (such as, the SRS resource set being triggered too early or the triggered SRS resource sets being overlapped in time and/or frequency domain) may be well handled, and the configuring and updating procedures for SRS resource may be more flexible.

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.
