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.

Abstract: Systems, apparatuses, methods, and computer-readable media are directed to techniques for codebook support for different antenna structures, such as a user equipment (UE) with a non-uniform antenna array (e.g. with different distances between antenna elements) and/or multiple antenna panels. Embodiments further provide techniques for enhanced operation in full power mode 2. For example, embodiments provide techniques for antenna virtualization to form virtual antenna ports from subsets of transmit antennas of the UE (e.g., from eight transmit antennas to two, four, or six virtual antenna ports). Other embodiments may be described and claimed.

Abstract: Various embodiments herein relate to a technique to be performed by a user equipment (UE) in a cellular network. The technique may include identifying, in a downlink control information (DCI) received from a first transmission and reception point (TRP), an indication of whether the UE is to operate in accordance with a single-TRP physical uplink shared channel (PUSCH) mode or a multi-TRP PUSCH mode: identifying, based on the indication, one or more resources for PUSCH transmission; and transmitting, based on the indication and the one or more resources, a first repetition of the PUSCH transmission and a second repetition of the PUSCH transmission. Other embodiments may be described and/or claimed.

Abstract: A computer-readable storage medium stores instructions to configure a UE for multiple component carrier repetition transmissions in a 5G NR network, and to cause the UE to perform operations comprising decoding DCI received via a PDCCH. The DCI includes transport block (TB) information and scheduling information. The scheduling information indicating scheduled transmissions of multiple repetitions of a PDSCH TB using multiple component carriers. A TB size associated with the scheduled transmissions is determined using the TB information. The multiple repetitions of the PDSCH TB am decoded. The multiple repetitions are received from one or more base stations during the scheduled transmissions. PDSCH data is determined based on the multiple repetitions of the PDSCH TB and the TB size.

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: 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.
