Abstract: Systems and methods disclosed herein relate to confirmatory signaling sent by a base station for the use of multiple physical uplink control channels (multi-PUSCH) or multiple physical downlink control channels (multi-PDSCH) scheduled in downlink control information (DCI) sent by the base station. Confirmatory signaling may be provided in the form of DCI, or in the form of a physical confirmation indicator channel (PCICH). Confirmatory signaling in DCI may confirm multi-PUSCH/multi-PDSCH scheduling according to one or more UE, and according to one or more CC used by each of the one or more UE using a bitmap. Confirmatory signaling in PCICH may confirm the multi-PUSCH/multi-PDSCH scheduling according to one or more UE. In these embodiments, a symbol for each such UE is spread according to different orthogonal covering codes (OCC), and such spreaded symbols are sent to the UE in a resource element set (RES) of a physical radio block (PRB).

Abstract: Configuring channel state information reference signal (CSI-RS) reporting at a network may include encoding a single CSI-RS reporting configuration for transmission to a user equipment (UE) that is in connected mode with both a first transmission and reception point (TRP) and a second TRP. The single CSI-RS reporting configuration may include a plurality of CSI-RS resource sets. Each of the plurality of CSI-RS resource sets may include a plurality of CSI-RS resources. At least one of the plurality of CSI-RS resource sets may include CSI-RS resources that correspond to the first TRP or the second TRP. A CSI measurement communication received from the UE may be decoded. The CSI measurement communication may be based on the single CSI-RS reporting configuration communication. Based on the CSI measurement communication, one or more downlink data transmissions may be scheduled.

Abstract: A wireless communication system may use enhanced feedback indicating a PDSCH decoding outcome. The enhanced feedback may be in an uplink control information (UCI) and carried over PUCCH or PUSCH. The enhanced feedback may be encoded and divided up into two parts of the UCI. A first payload may be carried in a first part of the UCI and a second payload comprising additional feedback information may be carried in a second part of the UCI.

Abstract: An approach to reduce the signaling overhead for tracking reference signal (TRS) configuration signaling to idle and inactive user equipments (UEs) operating in a wireless communication system. Conventional signaling approaches require more bits that can be conveyed in the maximum system information block (SIB) message size. One proposed approach optimizes the signaling by removing unnecessary or redundant information, using a single TRS configuration to replace multiple configurations, size reduction in some fields, and the sharing of some fields across different TRS configurations. Another proposed approach uses an SIB message to carry the TRS configurations for a particular beam or subset of beams. These two proposed approaches may be combined to provide further optimization possibilities.

Abstract: The exemplary embodiments relate to user equipment (UE) monitoring one or more downlink reference signals for uplink power control. The UE may receive an indication that a downlink reference signal is assigned to the UE for a first operation. The first operation is uplink power control for an uplink signal. The UE then determines whether the UE is configured to monitor the downlink reference signal for a second different operation. When the UE is configured to monitor the downlink reference signal for the second different operation, the UE configures the downlink reference signal to be a pathloss reference signal that is to be used for the first operation.

Abstract: A user equipment (UE) is configured to transmit physical uplink shared channel (PUSCH) transmissions having repetitions. The UE receives a first downlink control information (DCI) transmission from a base station of the wireless network, wherein the first DCI transmission schedules a first physical uplink shared channel (PUSCH) transmission having repetitions, transmits the PUSCH transmission with the one or more repetitions, receives a second DCI transmission from the base station, wherein the second DCI transmission indicates that the UE should modify the repetitions of the first PUSCH transmission and modifies the repetitions of the first PUSCH transmission.

Abstract: An approach is described for a user equipment (UE) to receive a channel state information (CSI) reporting configuration message from a source device of a first cell and receive a channel state information reference signal (CSI-RS) from a second cell via the source device. The UE determines a first number of CSI-RS resources of a first time slot duration corresponding to the first cell, a second number of CSI-RS resources of a second time slot duration corresponding to the second cell, an overall time slot duration based on the first and the second time slot duration, an overall number of CSI-RS resources of the overall time slot duration based at least on the first and the second number of CSI-RS resource, generates a capability report at least based on the overall number of CSI-RS resource, and transmits the capability report to the source device.

Abstract: Some aspects of this disclosure relate to apparatuses and methods for implementing techniques for a use equipment (UE) to determine, based on a transmission configuration indicator (TCI) state, a sensing beam to wirelessly communicate with a base station over a channel in an unlicensed spectrum. The UE can receive, using a receiving beam, control information including a TCI state, determine a sensing beam indicated by the TCI state included in the control information, sense a channel occupancy of the channel between the UE and the base station by performing Clear Channel Assessment using the sensing beam. Furthermore, the UE can determine, based on the channel occupancy, whether the channel is free to be utilized for communication by the UE using the sensing beam.
