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.

During operation each ACK/NAK feedback (200) comprises two fields (201-204). Each field corresponds to the status of previously-received data (e.g., slot, frame, TTI, . . . , etc.). In a first embodiment, field 1 corresponds to the current received data status, while field 2 corresponds to the previous received data status if a NAK misinterpretation error occurs. If the receiver detects no misinterpretation error, the second field is simply left blank. Because each ACK/NAK feedback will comprise the reception status of currently received data, and prior-received data, a transmitter has two chances to receive the NAK/ACK if a NAK misinterpretation error occurs.
摘要:
A method and apparatus for establishing an active set of carriers from a plurality of available carriers for a wireless receiver. The active set of carriers can be determined from the plurality of available carriers for the wireless receiver. An indication of which carriers are in the active set can be sent to the wireless receiver, such as a receiver in a mobile communication device. The receiver or mobile communication device can monitor only those carriers that are listed in the active set of carriers.

A base station (103) assigns a set of mobile stations (101) to a group wherein the group will share a set of radio resources. A shared control channel information element (501) is sent to the group of mobile stations (101) and provides a bitmap having fields for a control header (502), utilized resources (510), and first HARQ transmission assignments (530). HARQ subgroups may be defined to associate subgroups of mobile stations with specific HARQ transmission opportunities on the super-frame. The mobile stations (101) are assigned resources in a persistent manner in each long frame of a super-frame for which a first HARQ transmission opportunity is defined.
摘要:
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).
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 method and system for method for transmitting data in a communication network employing HARQ. The method includes a first step 502 of grouping data to be transported into a first group and a second group in accordance to a decision parameter, such as data size. A next step 504 includes concatenating data from the first group and encoding into a multi-user packet. A next step 502 includes encoding the data into a plurality of data packets. A next step 506 includes assigning available traffic resources to encoded packets. A next step 506 includes transmitting at least a first transmission of the encoded packets. A next step 510 includes reassigning 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.

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 base station (103) assigns a set of mobile stations (101) to a group wherein the group will share a set of radio resources (710). A shared control channel information element (501) is sent to the group of mobile stations (101) and provides a bitmap having fields for group ordering (511), resource allocations (530), failure handling resources (540), and an ordering pattern (513). If a mobile station fails to decode the shared control channel information element (501) it will access the failure handling resources in order to receive data. The failure handling channel may be persistent in some embodiments, or may be released after the mobile station is once again able to decode the shared control channel information element (501) and thereby share in the shared resource pool allocated to its mobile station group.
