Abstract: Separate forward dedicated and shared control channels (17, 18) are provided in a spread-spectrum communication. The forward dedicated control channel (1 8) is used to communicate persistent control information and point to the share d control channel (17) when further intermittent control information concernin g transmission of data to a mobile station (14) needs to be communicated. The use of a dedicated control channel for only necessary persistent control information, while only pointing to a shared control channel when it is needed, affords more efficient utilization of system resources.

Abstract: A communication system (100) provides selecting a first modulation-coding scheme (111), determining a first possible number of data bits (201), determining a first number of data (102) to be transmitted from the source user to the first destination user, and determining a first load level. If the first load level is unequal to a whole number, rounding to a next first whole number, selecting a first number of plurality of spreading codes (108-1 through 108- k) based on the first whole number of load level for spread coding of first number of data bits (102) after being modulated and coded according to selected modulation-coding scheme (111).

Abstract: A downlink frame (401) is divided in to similar sized resource blocks (403, 405, 407) with each co-channel sector scheduled to transmit from the beginni ng of its respective assigned resource block. Transmissions to remote units within the particular sector will occur only within the particular resource block, up to a point where all N resource units have been utilized. Beyond that point, additional transmissions are scheduled to be transmitted at the end of the resource blocks assigned to the other sectors.

Abstract: An apparatus and method for transmitting and receiving data, wherein retransmissions of information can be a different size from the initial transmission. The invention utilizes a partial Chase encoder 306 to truncate or expand data depending on the availability of channel resources for retransmission. A partial Chase combiner 314 processes the received demodulated data based solely on the number of codes and modulation received (i.e., predetermined, with no additional signaling required). If the received retransmission is smaller than the first transmission, only a portion of the soft bits are combined. If the retransmission is larger than the first transmission, some values of the stored first transmission are combined with more than one received soft bit in the retransmission.

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 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.
