摘要： The present invention is a method and apparatus for voice communication. Vocoded frames are transmitted using a transmission intervals. Each transmission interval is split into a first interval portion and a second interval portion. Code symbols associated with each vocoded frame are divided into a group A and a group B. The method includes transmitting group A code symbols of a first vocoded frame using a first interval portion of an interval i; decoding the group A code symbols received at the first interval portion of the interval i; performing an error detection code check on the first interval portion of the interval i; generating and sending a negative acknowledgment signal when the first interval portion of the interval i fails the error detection code check; and transmitting group B code symbols of the first vocoded frame using a second interval portion of an interval i+N.

摘要： Method and apparatus to provide a pseudo random noise (PN) sequence having a particular code phase offset for use in a radio in a Code Division Multiple Access (CDMA) radio system (100). In one embodiment, a first mask (320) is applied to shift a reference PN sequence to the assigned PN code phase (416). Upon reaching the end of the reference PN sequence, the initial state is reloaded (420) into the PN generator state register to reset the state value to its initial value, thereby producing a cyclical sequence. In a second embodiment, a first mask (622) and a second mask (624) are applied to the reference sequence produced by the PN generator state registers (620) to produce the appropriate portions of the output sequence.

摘要： A receiver (200) is provided receiving signals from differing base stations (BTSA and BTSB). The signal from BTSA is encoded using a first rate convolutional encoder while the signal transmitted from BTSB is encoded using a second rate convolutional encoder. Since the multiple base station links may result in a different number of symbols being received for each bit transmitted, the symbols received for each link cannot be simply combined. Therefore, in the preferred embodiment of the present invention, the resulting symbols are passed to multiple branch metric circuits (210–211), where branch metrics (μi) for the symbols are obtained. After the ith branch metrics for the base stations are computed, the branch metrics for each base station are passed to a combiner (212) where they are combined.
摘要翻译：接收器（200）被提供为接收来自不同基站（BTS＆lt; A＆gt;和BTS＆lt; B＆gt; B＆gt;）的信号。使用第一速率卷积编码器对来自BTS A的信号进行编码，而使用第二速率卷积编码器对从BTS B发送的信号进行编码。由于多个基站链路可能导致针对所发送的每个比特接收到不同数量的符号，因此不能简单地组合每个链路所接收的符号。因此，在本发明的优选实施例中，所得到的符号被传递到多个分支度量电路（210-211），其中获得用于符号的分支度量（μ∈Ii）。在计算了基站的第i个分支度量之后，将每个基站的分支度量传递到组合器（212），在组合器（212）中组合它们。

摘要： In the present technique of data transmission management provided, a composite status indicator value is assessed (716) based on multiple channel quality indicator reports over a predefined time. The assessed composite status indicator value is compared (718) to a first threshold value. If the assessed composite status indicator value does not correspond in at least a predetermined way to the first threshold value, the mobile station is classified (720) in a high speed data region. Otherwise, the assessed composite status indicator value is further compared (726) to a second threshold, and if it corresponds in at least a predetermined way to the second threshold, the mobile station is classified (734) in the low speed data region.

摘要： Various embodiments are described to address the need for a method and apparatus that could reduce the start-up delay for uplink data transfers in multiple-access technologies. A time-symbol threshold (551) is introduced for an uplink frame (550) in order to create a partition of the frame that includes the earlier of the available time symbols and in which any bandwidth request allocations may be placed. By placing bandwidth request allocations earlier in the uplink frame (i.e., at or before the time-symbol threshold), remote units are able to send their bandwidth requests to a scheduler sooner and thereby receive a bandwidth grant for an uplink data transfer with less delay.

摘要： A communication system provides a method and apparatus for interleaving data symbols of a block of data symbols (301) having data symbols from B(1) to B(n). The method and the accompanying apparatus include dividing block of data symbols (301) into a plurality of groups of data symbols (303 and 304). Each of the plurality of groups of data symbols (303, 304) includes data symbols equal in number to a fraction of data symbols B(1) through B(n), such as ½ and ⅓, such that the total number of data symbols in plurality of groups of data symbols (303, 304) substantially equals “n” data symbols. An interleaved block of data symbols (106) is formed by an alternating selection of data symbols from plurality groups of data symbols (303, 304). The alternating selection from each of plurality of groups of data symbols (303, 304) is according to either a forward addressing or a backward addressing mapping. A plurality of coded data symbols in a block of coded data symbols (104) is received for interleaving according to a single bit reversal interleaving function to form block of data symbols (301).
