Abstract
Methods and apparatuses for wireless communication are provided. In an aspect, Transmissions are received from multiple antennas of a user equipment and a differential power control message that is based on an imbalance of transmitted power from the multiple antennas is transmitted. In another aspect, a differential power control message that is based on an imbalance of transmitted power from multiple antennas of a user equipment is received and based on the message, the imbalance is compensated for by varying a transmit power from one or more of the multiple antennas.
Claims36
A method for wireless communications, comprising:
- receiving transmissions from multiple antennas of a user equipment;
- and
- transmitting a differential power control message that is based on an imbalance of transmitted power from the multiple antennas, wherein the differential power control message includes a common value and a differential value that is transmitted less frequently than the common value.
An apparatus for wireless communications, comprising:
- means for receiving transmissions from multiple antennas of a user equipment;
- and
- means for transmitting a differential power control message that is based on an imbalance of transmitted power from the multiple antennas, wherein the differential power control message includes a common value and a differential value that is transmitted less frequently than the common value.
An apparatus for wireless communications, comprising:
- at least one processor configured to receive transmissions from multiple antennas of a user equipment and to transmit a differential power control message that is based on an imbalance of transmitted power from the multiple antennas, wherein the differential power control message includes a common value and a differential value that is transmitted less frequently than the common value.
A computer-program product comprising a non-transitory computer-readable storage medium, the non-transitory computer-readable storage medium comprising:
- instructions for causing a computer to receive transmissions from multiple antennas of a user equipment;
- and
- instructions for causing the computer to transmit a differential power control message that is based on an imbalance of transmitted power from the multiple antennas, wherein the differential power control message includes a common value and a differential value that is transmitted less frequently than the common value.
A method for wireless communications, comprising:
- receiving a differential power control message that is based on an imbalance of transmitted power from multiple antennas of a user equipment (UE), wherein the differential power control message includes a common value and a differential value that is transmitted less frequently than the common value;
- and
- based on the message, compensating for the imbalance by varying a transmit power from one or more of the multiple antennas.
An apparatus for wireless communications, comprising:
- means for receiving a differential power control message that is based on an imbalance of transmitted power from multiple antennas of a user equipment (UE), wherein the differential power control message includes a common value and a differential value that is transmitted less frequently than the common value;
- and
- means for compensating for the imbalance, based on the message, by varying a transmit power from one or more of the multiple antennas.
An apparatus for wireless communications, comprising:
- at least one processor configured to receive a differential power control message that is based on an imbalance of transmitted power from multiple antennas of a user equipment (UE) and, based on the message, to compensate for the imbalance by varying a transmit power from one or more of the multiple antennas, wherein the differential power control message includes a common value and a differential value that is transmitted less frequently than the common value.
A computer-program product comprising a non-transitory computer-readable storage medium, the non-transitory computer-readable storage medium comprising:
- instructions for causing a computer to receive a differential power control message that is based on an imbalance of transmitted power from multiple antennas of a user equipment (UE), wherein the differential power control message includes a common value and a differential value that is transmitted less frequently than the common value;
- and
- instructions for causing the computer to compensate for the imbalance, based on the message, by varying a transmit power from one or more of the multiple antennas.
