Uplink power control using received reference signal
First Claim
1. A user equipment (UE) comprising:
- circuitry configured to receive control information on a downlink control channel from a base station;
wherein the control information includes first information and second information;
wherein the first information is an allocation of an uplink channel and the second information is used to derive a modulation and coding for the uplink channel;
wherein the circuitry is further configured in response to receiving the control information to produce a communication for transmission in the allocated uplink channel in a time interval including at least one time slot;
wherein the communication includes an adaptive modulation and coding report;
wherein a transmission power level of the communication is derived from at least the second information and a pathloss measured by the UE.

Abstract
A user equipment (UE) includes circuitry configured to receive control information on a downlink control channel from a base station. The control information indicates an allocation of an uplink channel and the control information is sent in response to the base station determining that the UE is to send an adaptive modulation and coding report. The circuitry is further configured in response to the control information to transmit a communication in the allocated uplink channel in a time interval including at least one time slot. The communication includes an adaptive modulation and coding report, and a transmission power level of the communication is derived from the control information and a pathloss measured by the UE.
