Discrete power level coding for indicating uplink mobile receive level in a wireless repeater system
First Claim
1. In a wireless cellular communication system having a base transceiver station located within a home cell and at least one substantially adjacent cell having a repeater located therein, a method for managing a plurality of mobile transceiver units, comprising the steps of:
- receiving at said repeater a signal from a mobile transceiver unit on an uplink communication channel;
measuring at said repeater a power level of said signal as received by said repeater; and
transmitting a backhaul signal from said repeater to said base transceiver station on a backhaul communication link, wherein said backhaul signal is selectively transmitted at one of a plurality of discrete power levels, each of said discrete power levels representing a coded indication of said power level as measured by said repeater.

Abstract
A method for managing a plurality of mobile units in a wireless cellular communication system having a plurality of repeater stations includes the step of receiving a signal on an uplink communication channel from a mobile transceiver unit at one of the repeaters. The method also measures at the repeater station a power level of the signal as received by the repeater station. The method further includes the step of transmitting a backhaul signal from the repeater station to the base transceiver station on a backhaul communication link, where the backhaul signal is transmitted at one of a plurality of discrete power levels providing an indication of the power level as measured by the repeater station.

9. A repeater in a wireless cellular communication system having a base transceiver station located within a home cell and a plurality of substantially adjacent cells at least one having said repeater located therein, said repeater comprising:
-
a receiver for receiving at one of said repeaters a signal from a mobile transceiver unit via an uplink communication channel; power measurement means for measuring at said repeater a power level of said signal as received by said repeater; and a transmitter for transmitting a backhaul signal from said repeater to said base transceiver station via a backhaul communication link, wherein said backhaul signal is transmitted at one of a plurality of discrete power levels selected in accordance with a predetermined coding scheme for providing an indication of said power level from the mobile transceiver as measured by said repeater. - View Dependent Claims (10, 11)

12. In a wireless cellular communication system having a base transceiver station located within a home cell, and a plurality of substantially adjacent cells, with at least one having a repeater located therein, a method for automatically controlling power level in a backhaul communication link, said link having at least one channel, the method comprising:
-
receiving at said repeater a signal from an uplink channel; measuring at said repeater a signal power level of said signal as received by said repeater; transmitting a backhaul signal from said repeater to said base transceiver station, wherein said backhaul signal comprises at least a traffic portion of said signal received from the uplink channel which is transmitted at one of a plurality of discrete power levels providing an indication of said signal power level as measured by said repeater; receiving at a base transceiver station said indication of said signal power level and said at least a traffic portion of said signal; and assigning channels in said wireless communication system at said base station, based on said signal power level. - View Dependent Claims (13, 14, 15)

16. A configurable base transceiver station in a communication system having the base transceiver station located within a home cell and a plurality of substantially adjacent cells, with at least one of said adjacent cells having a repeater located therein, said base transceiver station comprising:
-
a transmitter for transmitting traffic and control signals to the repeater; a receiver for receiving a backhaul signal from the repeater, wherein the backhaul signal is transmitted at one of a plurality of discrete power levels indicative of a power level measured from an uplink communication channel at the repeater; and a processor that is programmed to selectively configure the plurality of discrete power levels at which the repeater will transmit the backhaul signal, wherein the processor is further programmed to decrease the power level of the uplink channel if the backhaul signal is transmitting at a first power level, maintain the power level of the uplink channel if the backhaul signal is transmitting at a second power level, increase the power level if the backhaul signal is transmitting at a third power level, and request that the uplink channel handoff to another repeater or base transceiver station if the backhaul signal is transmitting at a fourth power level.
