Abstract
Aspects of the disclosure relate to beam configuration for RF repeaters. An RF repeater is configured to measure received power of one or more signals in the repeater for each of a plurality of beam directions. Further, the repeater determines a beam forming configuration for a fronthaul link between the repeater and at least one base station based on the measured received power of each of plurality of beam directions. The repeater may also be configured to determine beam configurations for access links between the repeater and user equipment.
Claims30
A method of beam forming in a repeater in a communication system, the method comprising:
- receiving one or more signals in the repeater for each of a plurality of beam directions;
- measuring received power of each of the one or more signals for each of the plurality of beam directions;
- and
- determining a beam forming configuration for transmissions on a fronthaul link between the repeater and at least one base station based on the measured received power of the one or more signals.
A wireless repeater device in a wireless communication network, comprising:
- a wireless transceiver;
- a memory;
- and
- a processor communicatively coupled to the wireless transceiver and the memory, wherein the processor and the memory are configured to:
- receive one or more signals in the repeater for each of a plurality of beam directions;
- measure received power of each of the one or more signals for each of the plurality of beam directions;
- and
- determine a beam forming configuration for transmissions on a fronthaul link between the repeater and at least one base station based on the measured received power of the one or more signals.
A method of beam forming in a repeater in a communication system, the method comprising:
- receiving one or more signals from at least one of a base station or one or more user equipment (UE);
- measuring received power for the received one or more signals at a plurality of beam locations except for beam locations selected for serving a fronthaul link between the repeater and the base station;
- and
- selecting a beam forming configuration for transmissions for an access link between the repeater and the UE based on the measuring of the received power of the one or more signals at the plurality of beam locations.
A wireless repeater device in a wireless communication network, comprising:
- a wireless transceiver;
- a memory;
- and
- a processor communicatively coupled to the wireless transceiver and the memory, wherein the processor and the memory are configured to:
- receive one or more signals from at least one of a base station or one or more user equipment (UE);
- measure received power for the received one or more signals at a plurality of beam locations except for beam locations selected for serving a fronthaul link between the repeater and the base station;
- and
- select a beam forming configuration for transmissions for an access link between the repeater and the UE based on the measuring of the received power of the one or more signals at the plurality of beam locations.
