Abstract
A clutter-induced interference at a base station is mitigated through a command from the base station to a user equipment that commands the user equipment to transmit using an increased transmit power. During acquisition, the command may comprise a SIB. During a connected mode of operation, the command may comprise a TPC message, assistance information, an RRC message, or a DCI message.
Claims29
A method of clutter mitigation for a base station, comprising:
- scanning through a plurality of antenna beams from the base station to identify an affected antenna beam that is subjected to a clutter-induced interference;
- transmitting a clutter-based power command from the base station using the affected antenna beam;
- and
- receiving at the base station a message from a user equipment having a transmit power that is increased from an initial transmit level responsive to the clutter-based power command.
1 more element
A base station, comprising:
- a processor configured to scan through a plurality of antenna beams to identify an affected antenna beam that is subjected to a clutter-induced interference;
- and
- a transceiver configured to transmit a clutter-based power command using the affected antenna beam, wherein the clutter-based power command is a command to a user equipment to increase a transmit power of the user equipment to mitigate the clutter-induced interference.
A method of clutter mitigation for a base station, comprising:
- during a connected mode of operation with a user equipment, transmitting from the base station a clutter-based power command indicating a presence of a clutter-induced interference at the base station;
- and
- receiving at the base station an uplink message having an increased transmit power relative to an initial transmit power responsive to the clutter-based power command, wherein the uplink message is selected from the group consisting of an in-band full duplex message and a sub-band frequency duplex message.
A base station, comprising:
- a processor configured to scan through a plurality of antenna beams to identify an affected antenna beam that is subjected to a clutter-induced interference;
- and
- a transceiver configured to transmit a clutter-based power command using the affected antenna beam, wherein the clutter-based power command is a command to a user equipment during a connected mode of operation to increase its transmit power to mitigate the clutter-induced interference, the transceiver being further configured to receive an uplink message from the user equipment having an increased transmit power relative to an initial transmit power level responsive to the clutter-based power command.
