Abstract
Communications sourced by a remote unit (14) that is already within reception range of a base site (10) can nevertheless be further facilitated through allocation of one or more relay resources (15, 16). Such relay resources, properly employed, then serve to effectively increase the quality of service for the facilitated communication. This, in turn, can permit the use of, for example, increased data rates for communications from a relatively low power remote unit.
Claims20
A method for a relay device to relay information, the method comprising the steps of:
- receiving the information on a first set of frequencies, the information transmitted using a first modulation and coding scheme;
- demodulating the received information;
- decoding the received information;
- and
- relaying the information on a second set of frequencies, the information relayed using a second modulation and coding scheme.
A method for a relay device to relay information within a communication system, the method comprising the steps of:
- receiving a message indicating subscriber stations to monitor;
- receiving an assignment message indicating a relay-to-base resource;
- receiving transmissions from the subscriber stations;
- demodulating and decoding the subscriber stations' transmissions;
- re-modulating and re-encoding the subscriber stations' transmissions;
- and
- relaying the re-modulated and re-encoded transmissions over the relay-to-base resource, wherein the transmissions are relayed in a predetermined order.
A method for a base station to receive relayed transmissions from a subscriber station, the method comprising the steps of:
- transmitting a control message comprising a relay identifier and one or more subscriber stations to monitor;
- transmitting an assignment message indicating a relay-to-base resource, wherein the relay-to-base resource is for relaying a plurality of transmissions from the one or more subscriber stations to monitor;
- and
- receiving transmissions on the relay-to-base resource from a relay station with the identifier
