Abstract
A user equipment (UE) in communication with a base station is configured by the base station for operation with an adapted time division duplex (TDD) uplink-downlink (UL-DL) configuration. A process enables UL power control for transmissions of various channels or signals from the UE in two different sets of UL transmission time intervals (TTIs) and a process enabling receptions of data transport blocks by the base station in two different sets of UL TTIs.
Claims20
A method, comprising:
- receiving, at a user equipment (UE):
- a configuration, by higher layer signaling, for first and second values for a parameter PO_UE_PUSCH associated with a nominal reception power of a physical uplink shared channel (PUSCH) at a reception point of a cell, and
- a downlink control information (DCI) format that schedules a transmission of a PUSCH from the UE to the reception point of the cell,
- wherein the DCI format includes a first field with a value indicating either the first PO_UE_PUSCH value or the second PO_UE_PUSCH value;
- computing a power for the PUSCH transmission to the reception point of the cell based on the PO_UE_PUSCH value indicated by the value of the first field;
- and
- transmitting the PUSCH from the UE to the reception point of the cell with the power for the PUSCH transmission.

A user equipment (UE), comprising:
- a receiver configured to receive:
- a configuration, by higher layer signaling, for first and second values for a parameter PO_UE_PUSCH associated with a nominal reception power of a physical uplink shared channel (PUSCH) at a reception point of a cell, and
- a downlink control information (DCI) format that schedules a transmission of a PUSCH to the reception point of the cell, wherein the DCI format includes a first field with
- a value indicating either the first PO_UE_PUSCH value or the second PO_UE_PUSCH value;
- a processor configured to compute a power for the PUSCH transmission to the reception point of the cell based on the PO_UE_PUSCH value indicated by the value of the first field;
- and
- a transmitter configured to transmit the PUSCH to the reception point of the cell with the power for the PUSCH transmission.

A base station, comprising:
- a transmitter configured to transmit:
- a configuration, by higher layer signaling, for first and second values for a parameter PO_UE_PUSCH associated with a nominal reception power of a physical uplink shared channel (PUSCH) at a reception point of a cell, and

- wherein the DCI format includes a first field with α value indicating either the first PO_UE_PUSCH value or the second PO_UE_PUSCH value for computing a power for the PUSCH transmission;
- and
- a receiver configured to receive the PUSCH.
