  • Publication number: 20210306867
    Abstract: User equipment (UE) includes processing circuitry coupled to memory. To configure the UE for multi-transmission reception point (TRP) reception, the processing circuitry is to decode radio resource control (RRC) signaling. The RRC signaling includes configuration information configuring a plurality of transmission configuration indication (TCI) states. A media access control (MAC) control element (CE) is decoded, where the MAC CE indicates multiple active TCI states of the configured plurality of TCI states. Multiple received beams are determined using the multiple active TCI states. Downlink information is decoded, where the downlink information originates from multiple TRPs and is received via the determined multiple receive beams associated with the multiple active TCI states.

  • Publication number: 20210212033
    Abstract: Embodiments described herein relate to downlink (DL) control channel signaling for an aperiodic channel state information (A-CSI) trigger. In one example, a user equipment (UE) communicates with a network to receive first configuration signaling to identify a first downlink control information (DCI) in a physical downlink control channel (PDCCH). The UE also receives, from the network, the first DCI. The first DCI is appended with cyclic redundancy check (CRC) bits that are scrambled by a common radio network temporary identifier (RNTI) and is to indicate an aperiodic channel state information (A-CSI) trigger. Next, the UE receives, from the network, channel state information (CSI) reference signals in one or more occasions that follow an occasion in which the first DCI is received and generates and transmits a CSI report in a physical uplink control channel (PUCCH) based on the CSI reference signals.

  • Publication number: 20200396722
    Abstract: Embodiments of a User Equipment (UE), generation Node-B (gNB) and methods of communication are generally described herein. The UE may receive, from a gNB, a narrowband physical downlink control channel (NPDCCII) that indicates a number of narrowband internet-of-things (NB-IoT) downlink subframes for a downlink scheduling delay of a narrowband physical downlink shared channel (NPDSCH) in one or more radio frames configured for time-division duplexing (TDD) operation. Subframes of the one or more radio frames may include uplink subframes, NB-IoT downlink subframes for downlink NB-IoT transmissions, and downlink subframes for other downlink transmissions. The UE may determine the downlink scheduling delay based on an earliest subframe for which a count of NB-IoT downlink subframes is equal to the number of NB-IoT downlink subframes indicated in the NPDCCH.

  • Publication number: 20200236524
    Abstract: Embodiments of a User Equipment (UE), generation Node-B (gNB) and methods of communication are generally described herein. The UE may receive a narrowband physical downlink control channel (NPDCCH) that includes an uplink scheduling parameter. The UE may determine an uplink scheduling delay for transmission of a narrowband physical uplink shared channel (NPUSCH) in accordance with time-division duplexing (TDD). The uplink scheduling delay may be based on a sum of a predetermined first number of subframes and a variable second number of subframes. The second number of subframes may be based on a window of variable size that starts when the first number of subframes has elapsed since reception of the NPDCCH, and ends when a number of uplink subframes has elapsed since the start of the window. The number of uplink subframes may be indicated by the uplink scheduling parameter.
