Abstract: A generation node B (gNB) configured for aperiodic channel state information reference signal (CSI-RS) triggering and transmission may encode signalling for transmission to a user equipment (UE). The signalling to indicate an aperiodic Triggering Offset (aperiodicTriggeringOffset). The aperiodic Triggering Offset may comprise a slot offset. The gNB may encode a downlink control information (DCI) for transmission that may trigger transmission of a CSI-RS in one or more aperiodic CSI-RS resource set(s) (i.e., in one or more slots (n)). The DCI triggers transmission of the aperiodic CSI-RS within a triggered slot with the slot offset (i.e., the aperiodic TriggeringOffset). The gNB may transmit the CSI-RS in resource elements of the triggered slot in accordance with the slot offset, when CSI-RS resources are available in the slot at the slot offset. The gNB may postpone transmission of the aperiodically triggered CSI-RS to a first available downlink slot when the CSI-RS resources are not available in the triggered slot at the slot offset.

Abstract: A user equipment (UE configured for multi-Transmission-Reception Point (M-TRP) operation in a fifth-generation (5G) new radio (NR) network with DCI activated PUCCH repetition with TX beam cycling may multiplex UCI on a scheduled PUSCH transmission to a first TRP, multiplex the UCI on a scheduled PUSCH transmission to a second TRP and drop repetitions of the PUCCH when a first repetition of the PUCCH overlaps the scheduled PUSCH transmission to the first TRP and the second repetition of the PUCCH overlaps with a scheduled PUSCH transmission to the second TRP. For multiplexing the UCI and dropping the PUCCH repetitions, a timeline condition may also need to be satisfied.

Abstract: A computer-readable storage medium stores instructions to configure a UE for beam management for multi-TRP operation in a 5G NR and beyond wireless network, and to cause the UE to perform operations. The operations include performing measurements on a plurality of SS/PBCH blocks to determine a set of preferred SS/PBCH beams. A MAC control element (CE) is encoded for transmission to a base station. The MAC CE includes at least one preferred beam pair for the multi-TRP operation. The at least one preferred beam pair includes a pair of preferred SS/PBCH beams selected from the set and corresponding to a pair of UE antenna panels. Downlink data received by the pair of UE antenna panels during the multi-TRP operation is decoded. The downlink data is received via reception beams corresponding to the pair of preferred SS/PBCH beams.

Abstract: Various embodiments herein provide techniques for a unified transmission configuration indicator (TCI) framework for multi-transmission-reception point (TRP) operation in a wireless cellular network. For example, embodiments may relate to use of a joint TCI codepoint to indicate one or more TCI states (e.g., a joint uplink (UL)/downlink (DL) TCI state, a UL TCI state, and/or a DL TCI state). The techniques may be used for multi-downlink control information (DCI) multi-TRP operation and/or single-DCI multi-TRP operation. Embodiments further relate to techniques for transmission repetition and uplink power control. Other embodiments may be described and claimed.

Abstract: Disclosed embodiments are related to beam management in cellular communication networks, and in particular, provide a new transmission (Tx) beamforming indication based on the flexible Tx beam-forming assignment on the corresponding reference signal configured in a transmission configuration indicator (TCI) state for downlink (DL) or spatial relation information in the uplink (UL). The Tx beam-forming on the reference signal of the TCI state configured for the DL physical channel/reference signal can be updated based on reported Tx beam in the UL or using UL measurements from Sounding Reference Signal (SRS) transmission. Similarly, spatial relation information configuration used to indicate Tx beam-forming in the UL, may be also updated based on the reference signal measurements in DL or by suing Downlink Control Information (DCI) based beam indication in a scheduling request indicator (SRI). Other embodiments may be described and/or claimed.

Abstract: User equipment (UE) includes processing circuitry, where to configure the UE for New Radio (NR) communications in an unlicensed spectrum, the processing circuitry is to decode radio resource control (RRC) signaling including configuration information identifying a physical downlink control channel (PDCCH) search space set. The configuration information includes a PDCCH monitoring periodicity, a PDCCH monitoring offset, and a PDCCH monitoring duration associated with the PDCCH search space set. The PDCCH search space set is monitored for downlink control information (DCI) using the PDCCH monitoring periodicity, the PDCCH monitoring offset, and the PDCCH monitoring duration. Upon detecting the DCI within the monitored PDCCH search space set, a DCI format within the DCI is decoded.

Abstract: A user equipment (UE) may determine one or more nominal time-domain windows (TDWs) for demodulation reference signals (DMRS) bundling for physical uplink control channel (PUCCH) transmissions of a PUCCH repetition. A start of a new actual TDW for the DMRS bunding is determined in response to an event which causes power consistency and phase continuity not to be maintained across the PUCCH transmissions of the PUCCH repetition. The UE may maintain power consistency and phase continuity within the new actual TDW across two PUCCH transmissions of the PUCCH repetition. The event may comprise a use of different power control parameters for the two of the PUCCH transmissions of the PUCCH repetition within one of the nominal TDWs.
