Abstract
A method and apparatus for assigning a communication resource is disclosed. The method includes allocating a channel by a base station or Node B 102. The base station or Node B detects an energy level transmitted on the channel wherein the energy level may contention-free for a plurality of user equipment 104. The base station or Node B assigns time frequency resources for at least one of the plurality of user equipment wherein the time frequency resources are proportional to the detected energy level.
Claims20
A method for assigning a communication resource, the method comprising:
- allocating a channel;
- detecting an energy level transmitted on the channel, and
- assigning time frequency resources for at least one of a plurality of user equipment wherein the time frequency resources are proportional to the detected energy level.
A method of transmitting uplink control data, the method comprising:
- sending an indicator on an allocated channel wherein the allocated channel is a common time-frequency region for use by a plurality of user equipment;
- monitoring an uplink grant for a specific identifier;
- sending a UL control/data on an assigned shared data channel using a code specific to each of the plurality of user equipment.
An apparatus for assigning communication resources, the apparatus comprising:
- a transceiver for transmitting and receiving signals, and
- a controller coupled to the transceiver, the controller operable to allocate a channel, detect an energy level of a signal received on the channel by the transceiver, assign time frequency communication resources for at least one of the plurality of user equipment wherein the number of time frequency resources is proportional to the detected energy level and send the time frequency communication resources to the at least one of the plurality of user equipment by the transceiver.
