Obtaining channel quality information in a wireless communication network

摘要

Obtaining channel quality information in a wireless communication network is described. A base station allocates a resource to remote stations in order to receive channel quality information back from remote stations. The resource allocated to a remote station contains no higher layer data. A scheduler in the base station uses the channel quality information in order to schedule remote stations and/or to decide on the channel coding and/or modulation to be applied to the data transmission. A mechanism is provided to ensure that data transmitted on HS-DSCH is not transmitted to higher layers. This may provide a convenient method of obtaining channel quality information allowing for improved scheduling and thus improved performance of the communication system.
