PROBLEM TO BE SOLVED: To provide a method and apparatus for indicating to a communication unit a plurality of modulation and coding schemes (MCSs) to be utilized for communication. SOLUTION: A first MCS is determined for first resource blocks to be sent to a first remote unit or base station, and a second MCS is determined for a second resource block to be sent to the remote unit or base station; and a message is transmitted, indicating the first and the second MCS and also indicating the first resource blocks and the second resource block. Finally, a first PDU is transmitted to the remote unit or base station at a first time, by using the first MCS, and the first resource blocks and a second PDU is transmitted to the remote unit or base station at the first time, by using the second MCS and the second resource block.

Abstract:
PROBLEM TO BE SOLVED: To provide a resource assignment system which produces a better trade off between a performance of a cell outer and an overall spectrum efficiency. SOLUTION: A power control parameter fraction is determined, based on the maximum transmission power, a propagation loss threshold and a channel condition. A data rate which can be supported is determined, based on a transmitting power level, and a minimum bandwidth is determined, based on the data rate which can be supported.

Abstract:
PROBLEM TO BE SOLVED: To provide a wireless communication terminal which communicates by a plurality of subcarriers which are divided into a plurality of frequency bands that include one or more subcarriers, respectively. SOLUTION: The wireless communication terminal measures a channel quality indicator (CQI) of a plurality of frequency bands (310), discriminates a subset of a frequency band whose channel quality indicator is measured (320), and transmits a report which discriminates a subset of a frequency band whose channel quality indicator is measured or transmits a report which discriminates a frequency band that is not included in the subset (330). In some embodiments, a subset CQI value related to a subset of frequency band is included in the report at least. COPYRIGHT: (C)2007,JPO&INPIT
Abstract:
A method for scheduling a wireless communication entity based on channel quality information provided by the wireless entity, wherein scheduling is discontinued if channel quality information is not received from the wireless communication entity over a specified number of frames or if the channel quality information provided is insufficient to support a control channel. The wireless communication entity may discontinue reporting channel quality information if the channel quality measured over a specified number of frames is below a threshold. Scheduling may be discontinued by blocking, removing or preempting the scheduling of the wireless entity.

Abstract:
A wireless communication device for receiving a frame corresponding to a transmission time interval, the frame having a control channel including at least two control channel elements and an embedded bit sequence, the location of which indicates a portion of the control channel used for radio resource assignment, wherein the portion of the control channel used for radio resource assignment may be less than the entire control channel of the frame having the embedded bit sequence, and wherein the at least two frames may use different portions of the control channel for radio resource assignment.
Abstract:
A method in a wireless communication device may include receiving a plurality of sub-frames, each sub-frame having time-frequency resource elements, at least one of the sub-frames having a control channel. In some implementations, the plurality of sub-frames forms a continuum of concatenated sub-frames. Each of the plurality of resource allocation fields of the control channel may indicate a resource assignment to the wireless communication device based on a channel quality report, as well as resource assignments in sub-frames of the continuum of concatenated sub-frames. At least one sub-frame of the continuum of concatenated sub-frames may include information indicating that at least some of the resource assignments are frequency diverse.
