    摘要: Transmission of candidate-sector signalling channels are synchronized to facilitate mobile-assisted handoff (MAHO) measurements by a mobile (125). Transmitters in candidate sectors each transmit their signalling channel at distinct frequencies and at predetermined intervals. The transmission of each signalling channel by each candidate sector transmitter is synchronized to provide a known reference to the mobile (125). When instructed, the mobile (125) need only to perform MAHO measurements at the predetermined intervals in the order and at the frequency instructed.

    摘要: In a time division multiple access (TDMA) system (10), a method (50, 60) of recovering a data signal of a transmission burst commences by obtaining the frequency transmission codes for the transmitters to be monitored (52, 62). The data signal is then received in separate transmission bursts from a first transmitter in a first time period (53, 65) and from a second transmitter in a second time period (56, 65). The data signal of one of the received transmission bursts is then selected or a plurality of the data signals are combined (58, 69) to be used by the receiver as the received data signal.

    摘要: An electronic system and a method substantially eliminates any delays caused by buffering of a signal containing speech. The electronic system comprises a receiver for receiving signals, a buffer, coupled to the receiver, a buffer controller coupled to the buffer, and an audio section for presenting signals received to a listener. The method comprises the following steps. The receiver receives an input signal representing speech, and produces an output signal representing the input signal after a delay intentionally introduced in the system. The delay corresponds to the length of the buffer. The buffer stores the input signal in the buffer at an input rate, and produces the output signal at an output rate. The buffer controller determines whether the delay or buffer length is greater than a predetermined threshold, and analyzes at least a portion of the input signal stored in the buffer to determine which parts of the input signal may be removed without substantial deterioration of the signal quality according to at least one predetermined criterion, when the buffer length is greater than a predetermined length. The buffer controller then deletes at least some of the parts of the input signal stored in the buffer that comply with the predetermined criterion.

    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.

    摘要: A wireless communication infrastructure entity assigns a plurality of schedulable wireless communication entities to a group wherein each entity is assigned a location within the group. The infrastructure entity indicates which of the plurality of schedulable wireless communication entities assigned to the group have been assigned a wireless resource, for example using a terminal assignments field (910) and indicates special transmission information using a special transmissions field (905). The special transmissions field (905) is used to indicate which of the schedulable wireless communication entities are receiving a special transmission.

    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 (770). 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), continuation resources (540) for HARQ, and an ordering pattern (513). If a mobile station requires retransmission it will access the resources indicated by the continuation resources field (54) in order to receive data. The HARQ blocks may be assigned to a mobile station based upon an index (601) which may correspond to the mobile station vocoder rate. Further, HARQ subgroups may be defined to associate subgroups of mobile stations with specific HARQ transmission opportunities on the super-frame and allocated by a rotating bitmap.
