Abstract
The invention refers to performing an automatic gain control—AGC—with respect to a received signal comprising a plurality of consecutive subframes (S1 S12), comprising identifying subframes that are associated to a first subset of the consecutive subframes (S1, S3, S4, S5, S7. S8, S9, S11, S12), performing a first (10) signal power measurement with respect to the received signal during the first subset of the consecutive subframes, and performing the AGC according to the first signal power measurement. The invention further refers to a user equipment and to a corresponding computer program.

A method for performing an automatic gain control (AGC) with respect to a received signal, the received signal comprising a plurality of consecutive subframes, the method comprising:
- identifying subframes that are associated with a first subset of the consecutive subframes;
- performing a first signal power measurement with respect to the received signal during the first subset of the consecutive subframes;
- performing a second signal power measurement with respect to the received signal during a second subset of the consecutive subframes, the second set comprising the subframes that are not comprised by the first subset;
- performing the AGC according to the first signal power measurement during the subframes of the first subset;
- performing the AGC according to the second signal power measurement during the subframes of the second subset.
A user equipment, comprising:
- a receiver configured to receive a signal comprising a plurality of consecutive subframes;
- a processing circuit configured to identify subframes that are associated with a first subset of the consecutive subframes;
- a measurement circuit configured to:
- perform a first signal power measurement with respect to the received signal during the first subset of the consecutive subframes;
- perform a second signal power measurement with respect to the received signal during a second subset of the consecutive subframes, the second subset comprising the subframes that are not comprised by the first subset;
- a variable amplifier configured to:
- perform Automatic Gain Control (AGC) of the received signal according to the first signal power measurement during the subframes of the first subset;
- and
- perform the AGC according to the second signal power measurement during the subframes of the second subset.
A user equipment, comprising:
- processing circuitry;
- memory operatively connected to the processing circuitry, wherein the memory comprises instructions executable by the processing circuitry to cause the user equipment to:
- identify subframes that are associated to a first subset of the consecutive subframes;
- perform a first signal power measurement with respect to the received signal during the first subset of the consecutive subframes;
- perform a second signal power measurement with respect to the received signal during a second subset of the consecutive subframes, the second subset comprising the subframes that are not comprised by the first subset;
- perform Automatic Gain Control (AGC) according to the first signal power measurement during the subframes of the first subset;
- perform AGC according to the second signal power measurement during the subframes of the second subset.
A computer program product stored in a non-transitory computer readable medium for controlling performance of automatic gain control (AGC) with respect to a received signal, the received signal comprising a plurality of consecutive subframes, the computer program product comprising software instructions which, when run on a processing circuit of a user equipment, causes the user equipment to:
- identify subframes that are associated with a first subset of the consecutive subframes;
- perform a first signal power measurement with respect to the received signal during the first subset of the consecutive subframes;
- perform the AGC based on the first signal power measurement.
