摘要:
A technique for transmitting data in a communication network employing Hybrid Automatic Repeat Request includes a first step 502 of grouping data to be transported into a first and second groups in accordance to a decision parameter, such as data size. A next step 504 concatenates data from the first group and encodes into a multi-user packet. A next step 502 encodes the data into a plurality of data packets. A next step 506 assigns available traffic resources to encoded packets. A next step 506 transmits the encoded packets. A next step 510 reassigns a portion of said traffic resources for which a positive acknowledgement has been determined to uninitiated packets or to assist with one or more ongoing transmissions.

A communication system distributes, in the time domain, acknowledgment transmissions by a group of access terminals sharing a same time domain resource. A position of one or more access terminals in the group of access terminals is determined and each of the one or more access terminals then sends an acknowledgment transmission, such as an acknowledgment or negative acknowledgement, in a time slot that is N time slots after the shared time domain resource, where N is a function of the position of the access terminal in the group of access terminals.

The PDCAB packet (300) and the RRA packet (308) are transmitted together on the F-SCCH. For example, 9 RRA bits (305) are appended to the PDCAB field (303), in place of the pad bits (205), thereby allowing both the PDCAB (303) and RRA (311) messages to be protected against errors by a 16-bit CRC (307). In accordance with the embodiments, a receiver is able to distinguish between the varying PDCAB (303) and RRA (305) message formats and transmitting the packets (300) and (308) together is a normal mode of operation in the embodiments. Therefore, in accordance with the embodiments, when the PDCAB packet (300) and RRA packet (308) are transmitted together, the network replaces the N PDCAB pad bits, such as pad bits (205), with the first N bits from the RRA bitmap (311), in order to use the nominal CRC length for both packets (300) and (308).

A base station (214) and the mobile station (202) can arrange the multiple antenna configuration by receiving a base station parameter that is related to a preference for one of a plurality of multiple antenna configurations of the base station. The method includes sending the selected multiple antenna configuration to a base station so that the base station can designate and establish the multiple antenna configuration to be used for communications between the base station and the mobile station. If conditions change at either the base station or the mobile station, the present invention can adjust the selected multiple antenna configuration to accommodate the changed condition.
摘要:
A method and system for processing, in a wireless communication device, data concerning a group resource allocation enables efficient use of radio frequency resources. The method includes processing a group properties message received from a radio access network (block 1410). The group properties message comprises group properties for a scheduling group, and the group properties comprise a group identifier that identifies the scheduling group. A group assignment message received from the radio access network is then processed (block 1425). The group assignment message comprises the group identifier and a position assignment within the scheduling group. The group properties are then associated with the group assignment message (block 1430).
摘要:
A system, method, and apparatus for establishing headroom for a mobile station operating in a wireless communication system by determining (230) a communication channel variance condition and establishing (245) a headroom value based on the communication channel variance condition. The headroom value may be further revised by determining (260) if a battery condition in a mobile station relates to a low battery level and increasing (265) the headroom value in order to decrease the maximum data rate. Modifications to headroom allow data rates to be tailored to specific channel variance conditions and battery conditions.
摘要:
A communication device and method for controlling reverse link transmissions. The device receives a broadcast transmission signal and determines a quality level of the broadcast transmission signal. It then communicates with the base station to establish how frequently reverse link transmissions will occur depending on the determined quality level. Alternatively, a network element can determining when a parameter crosses a threshold and transmit a message to select wireless communication devices to start gating on a reverse link when the parameter crosses the threshold.
