Abstract: A receiver (350) compatible with both wide channel constant envelope 4 level FSK FM modulation and narrow channel .pi./4 differential QPSK linear modulation allows compatible interaction between modified constant envelope and non-constant envelope transmitters (300). All Nyquist filtering occurs in the transmitters (300), and none in the receiver (350).

Abstract: A wireless communication infrastructure entity configured to allocate radio resources, in a radio frame, to a wireless terminal compliant with a first protocol and to a wireless terminal compliant with a second protocol. The radio frame including a first protocol resource region and a second protocol resource region. The radio frame including a first protocol allocation control message that allocates resources within the first protocol resource region to the wireless terminal compliant with the first protocol, and a second protocol allocation control message that allocates resources within the second protocol resource region to the wireless terminal compliant with the second protocol.

Abstract: A base station (101) will request the transmission of quality information from a particular remote stations (102, 103) only when data is queued to be transmitted to the remote stations. Once a remote station begins the transmission of channel quality information, the transmission of such information continues until the data transmission is successfully delivered to the remote station. The base station receives the channel quality information and adjusts the modulation and coding of the remote stations accordingly. Where data is transmitted simultaneously to a plurality of remote stations, a set of queues (303) for the multiple remote stations is maintained, and based on queue status, a channel quality request messages is sent to a sub-set of remote stations with data queued.

Abstract: In a wireless communication infrastructure entity (112) wherein information is communicated in a frame comprising multiple sub-frames, a method comprises grouping at least one wireless communication terminal (102) in a first group and grouping at least one separate wireless communication terminal in a second group, assigning the first and second groups to at least one common sub-frame, but less than all sub-frames constituting a common frame and assigning a control channel of the at least one common sub-frame to the first and second groups.

Abstract: A mobile station (110) selects an initial data rate for communication between base station (107) and mobile station (110). Mobile station (110) communicates the selected initial data rate to base station (107) through uplink (112). Base station (107) determines a difference level of interference condition experienced by mobile station (107) between a time when the initial data rate was selected by mobile station (110) and a time when base station (107) prepares to communicate to mobile station (110). Base station (107) selects a final data rate for transmission from base station (107) to mobile station (110) based on the determined difference level of interference condition. As such, the initial data rate may be modified to the final data rate while maximizing the down link capacity.

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.
