Selective carrier amplification in a wireless repeater

摘要

A method in a wireless repeater selects one or more carriers out of all carriers for amplification and transmission. The non-selected carriers may be blocked to mitigate delay spread, uplink noise contribution or other effects on the repeater environment due to multiple repeaters. The carriers may be selected based on signal characteristics, signal usage, and/or other parameters.

主权项

1. A method in a first wireless repeater, comprising:
receiving an input signal of an uplink or downlink transmission at a first antenna and transmitting an output signal of the respective uplink or downlink transmission on a second antenna of the first wireless repeater, the input signal being associated with a plurality of carriers; selecting at least one carrier for downlink transmission from the plurality of carriers, wherein the selected at least one carrier is different than a carrier for a second repeater proximate to the first repeater, wherein a hash function that excludes selection of the carrier for the second repeater is used, at least in part, to select the at least one carrier for the first repeater; selecting at least one carrier for uplink transmission corresponding to the selected carrier for downlink transmission and amplifying and transmitting only the selected at least one carrier for at least the uplink transmission.
