Abstract: A system and method for incremental redundancy transmission in a communication system. A time slot is provided having at least one sub-slot with a fixed size, and a data block sized to fit in the sub-slot, a header having a one data block sequence number in the header for the time slot. A parity block is sized smaller than the data block such that the parity block and the data block sequence number fit within the sub-slot. The data block and parity block are trnasmitted in the sub-slot within the time slot. In the header for the time slot the number of data blocks and parity blocks transmitted are identified.

Abstract: A digital cellular/personal communications service (PCS) application incorporates a logical link connection (LLC) server. In this approach, there are two ATM connections in the path of an AAL-2 connection: one between a base station and the LLC Server and the other between the LLC Server and a vocoder group. All LLCs from, or to, a given base station use a common ATM connection irrespective of the vocoder used at the other end. Similarly, all LLCs from, or to, a given vocoder group use a common ATM connection irrespective of the destination base station at the other end. At the LLC Server, LLC packets from many base stations destined for the same vocoder group are extracted and bundled into the ATM connection between the LLC Server and the destination vocoder group. Similar treatment is given to the packets originating at vocoders and destined for base stations. Thus, each ATM connection between a particular base station and the LLC server and each ATM connection between the LLC Server and a particular vocoder group are used to maximum capacity notwithstanding each ATM connection conveys LLCs to different LLC endpoints.

Abstract translation: 数字蜂窝/个人通信服务（PCS）应用包括逻辑链路连接（LLC）服务器。 在这种方法中，在AAL-2连接的路径中有两个ATM连接：一个在基站和LLC服务器之间，另一个在LLC服务器和声码器组之间。 来自或给予基站的所有LLC使用公共ATM连接，而与另一端使用的声码器无关。 类似地，来自或给定的声码器组的所有LLC使用公共ATM连接，而不管另一端的目的地基站如何。 在LLC服务器上，来自许多同一个声码器组的基站的LLC数据包被提取并捆绑在LLC服务器和目的声码器组之间的ATM连接中。 对来自声码器并发往基站的分组进行类似的处理。 因此，尽管每个ATM连接将LLC传送到不同的LLC端点，但是使用特定基站和LLC服务器之间的每个ATM连接以及LLC服务器和特定声码器组之间的每个ATM连接来实现最大容量。

Abstract: Disclosed is a method of sub-packet adaptation based on data rate. Specifically, the size of a sub-packet is adapted to a data rate at which the sub-packet is to be transmitted. In one embodiment, the sub-packet is size adapted to the data rate in a format that would allow such size adapted sub-packet to be soft combined with another sub-packet of a same or different size. The size adapted sub-packet may be transmitted prior to or after the other sub-packet.

Abstract: Disclosed is a method of data rate adaptation based on channel conditions. Data is initially transmitted at a first data rate based on a measured first channel condition and subsequently re-transmitted at a second data rate based on a measured second channel condition, wherein the first channel condition is measured prior in time to the second channel condition.

Abstract: A system and method to measure channel quality in terms of signal to interference plus noise ratio for the transmission of coded signals over fading channels in a communication system. A Viterbi decoder metric for the Maximum Likelihood path is used as a channel quality measure for coherent and non-coherent transmission schemes. This Euclidean distance metric is filtered in order to smooth out short term variations. The filtered or averaged metric is a reliable channel quality measure which remains consistent across different coded modulation schemes speeds. The filtered metric is mapped to the signal to interference plus noise ratio per symbol using a threshold based scheme. Use of this implicit signal to interference plus noise ratio estimate is used for the mobile assisted hand off in a cellular system, power control and data rate adaptation in the transmitter.
