Abstract: Configuring non-zero-power channel state information reference signal (NZP-CSI-RS) may include encoding a channel state information (CSI) configuration communication for transmission to a user equipment (UE) that is in connected mode with both a first transmission and reception point (TRP) associated with a serving cell and a second TRP associated with a neighbor cell. The NZP-CSI-RS configuration communication may establish a plurality of parameters for NZP-CSI-RS in the serving cell and the neighbor cell.

Abstract: A user equipment (UE) associated with a wireless communication system is disclosed. The UE comprises a processor configured to receive a first downlink control information (DCI) for scheduling a first physical downlink shared channel (PDSCH). The first DCI includes a non-numerical (NN) value of K1 for hybrid automatic repeat request (HARQ)-ACK feedback. The processor is further configured to determine a first priority class associated with the first PDSCH, and determine K1 value and priority class associated with one or more subsequent PDSCH received from the base station, until a selected PDSCH having a numerical K1 value and a same priority class as the first priority class is identified. Further, the processor is configured to provide HARQ feedback associated with the first PDSCH using a PUCCH/PUSCH occasion indicated by a second DCI scheduling the selected PDSCH.

Abstract: SL-DRX involves both Uu and PC5 interfaces. For an RRC_CONNECTED UE (also referred to as a connected mode UE, or simply connected UE), several SL-DRX enhancements are described in this disclosure to trigger SL DRX and share configurations. Alignment of SL-DRX alignment with Uu-DRX (referred to as Uu/SL DRX alignment or simply alignment) is also described, as an optional feature (since not all schedules can temporally align).

Abstract: User equipment (UE) operation in a single frequency network (SFN). The UE may receive one or more transmission configuration indication (TCI) states corresponding to one or more downlink resources, receive a demodulated reference signal (DMRS) wherein the DMRS is quasi co-located (QCLed) with one or more channel state information reference signal (CSI-RS) from multiple cells of a SFN and quasi co-location (QCL) information is included in the one or more TCI and determine a time and frequency offset corresponding to each of the multiple cells based on the CSI-RS.

Abstract: Methods, systems, and devices for signaling in cast-type indication for a wireless communication system may include receiving, at a first user equipment (UE), a first stage sidelink control information (SCI) format from a second UE, decoding the first stage SCI format, determining a second stage SCI format using the decoded first stage SCI format, decoding the second stage SCI format, and determining a sidelink feedback status using the second stage SCI format. The sidelink feedback status may indicate whether sidelink feedback is enabled or not enabled. Second stage SCI content may include a distance setting associated with a communication range between the first UE and the second UE.

Abstract: Methods and devices for a base station acting as a primary cell to perform dual spectrum sharing (DSS) with a first user equipment device (UE) over a 5G NR connection and a second UE over an LTE connection. The first UE establishes the 5G NR connection with the primary cell and one or more secondary cells. One of the secondary cells is configured in the 5G NR connection to provide downlink control information to the UE for the primary cell, to avoid collisions by the primary cell with LTE control transmissions.

Abstract: Apparatuses, systems, and methods may use an smtc information element or an smtc2-LP information element to calculate timing of a first measurement period to evaluate a serving cell while the UE is in idle mode or inactive mode. Additionally, apparatuses, systems, and methods may use the smtc information element or the smtc2-LP information element to calculate timing of a second measurement period to evaluate intra-frequency cells while the UE is in idle mode or inactive mode.

Abstract: Methods and apparatus provide for a wireless network to enable multiple-transmission reception point (multi-TRP) uplink (UL) time division multiplexed (TDMed) repetition transmission. The network may receive, from a user equipment (UE), beam measurements of downlink reference signals associated with a plurality of UL transmission beams from the UE to the multi-TRP. Based on criteria associated with the beam measurements received from the UE, the network enables the UE for the multi-TRP UL TDMed repetition transmission using the plurality of UL transmission beams. In addition, or in other scenarios, coordination is provided between the network and the UE to improve UL TDMed repetition transmissions when a UE switches between antenna panels.

Abstract: Techniques described herein include solutions for beam management in sidelink (SL) communications. In some aspects, user equipments (UEs) operating in SL are configured with a SL beam management resource pool by a base station. The SL beam management resource pool may be used to send a beam management message, such as a beam acquisition message, a beam failure recovery message, a beam maintenance message, etc. In some aspects, a resource in the SL beam management resource pool used to transmit the beam management message is selected based on an optimal beam determined by the UE. Resource pool configurations are provided for beamed transmission and beamed receiving, beamed transmission and quasi-omni receiving, and Rx beam training.

Abstract: Methods to enhance the coverage of NR systems for coverage-limited wireless devices are disclosed. A serving base station may configure a coverage-limited UE with parameters for the UE to operate in a coverage enhancement mode through RRC signaling, DCI, or RAR grant. The UE may use the configuration parameters to determine whether to enter into the coverage enhancement mode when connecting and communicating with the serving base station. The configuration parameters may configure the UE to exploit both time diversity and frequency diversity to extend and enhance coverage when receiving the PDSCH and PDCCH channels, when transmitting the PUSCH and PUCCH channel, and when transmitting PUSCH Msg3 during random access. Advantageously, the base station may flexibly and dynamically configure the UE with coverage enhancement parameters to extend the coverage of the UE using time diversity and frequency diversity gains as the UE moves around.
