  • Publication number: 20210320776
    Abstract: A user equipment (UE) is described. The UE includes receiving circuitry configured to receive a downlink control information (DCI) format. The DCI format includes a channel state information (CSI) request field set to trigger an aperiodic CSI reporting. The UE also includes transmitting circuitry configured to perform, based on the detection of the DCI format. The aperiodic CSI reporting includes a channel quality indicator (CQI) using a physical uplink shared channel (PUSCH). In a case that cyclic redundancy check (CRC) attached to the DCI format is scrambled by a cell radio network temporary identifier (C-RNTI), a first CQI table is used for interpretation for indices of the CQI. In a case that CRC attached to the DCI format is scrambled by a first RNTI different from the C-RNTI, a second CQI table is used for interpretation for indices of the CQI.

  • Patent number: 11082993
    Abstract: A terminal device transmits a signal to a base station apparatus through uplink. The terminal device considers a priority level for multiple MAC control elements in the logical channel prioritization procedure for the uplink, in a case where initial transmission is performed. At least first and second MAC control elements are included in the multiple MAC control elements. The first MAC control element provides the base station apparatus with information on an amount of first data available for transmission within a first buffer for the uplink. The second MAC control element provides the base station apparatus with information on amount of second data available for transmission within a second buffer for a first link that is used for communication between the terminal device and a different terminal device. The first MAC control element has a higher priority level than the second MAC control element except when being included for padding.
