摘要： This invention provides interference predictions, suitable for least interference dynamic channel assignment use or other frequency hopping uses by de-coupling the time slot assignment and the frequency hopping pattern assignment. In particular, a least interfered time slot is selected based on an aggregate interference measurement performed across an entire transmission band or a pre-specified range of frequencies in the transmission band. A user is assigned a least interfered time slot and provided an appropriate frequency hopping pattern.

摘要： A system for implementing Incremental Redundancy (IR) operations in a wireless receiver includes a baseband processor, an equalizer, a system processor, and an IR processing module. The baseband processor receives an analog signal corresponding to a data block and samples the analog signal to produce samples. The equalizer receives the samples from the baseband processor, equalizes the samples, and produces soft decision bits corresponding to the data block. The equalizer may be implemented as a distinct processing component or may be performed by the baseband processor or system processor. The system processor receives at least the soft decision bits and initiates IR operations. The IR processing module receives the soft decision bits of the data block and performs IR operations on the data block in an attempt to correctly decode a corresponding data block.

摘要： An arrangement where, in addition to the control channels that are used to set up sessions, there is a logically and physically separate and independent set of control channels that can be used as session control channels. Illustratively, the physical GSM frame arrangement that employs 8 logical slots is used, with one slot both in the uplink and downlink dedicated to these separate control channels. In the downlink, such a control channel provides channel grant information, requests to make and transmit power measurements, poll mobile units, etc. In the uplink, such a control channel can be used to request access to a traffic channel, to report on power measurements, to request special hand-off handling, to respond to polling, etc. Because the uplink session control channel does not need to carry a significant amount of information, the GSM slot can be divided into minislots, with each minislot constituting a session control channel for a group of mobile units.
摘要翻译：除了用于建立会话的控制信道之外，还有一个逻辑上和物理上分开且独立的控制信道集合，可用作会话控制信道。示例性地，使用采用8个逻辑时隙的物理GSM帧布置，其中专用于这些单独控制信道的上行链路和下行链路中的一个时隙。在下行链路中，这样的控制信道提供信道授权信息，发送功率测量的请求，轮询移动单元等。在上行链路中，可以使用这样的控制信道来请求访问业务信道，报告功率测量，请求特殊切换处理，以响应轮询等。由于上行会话控制信道不需要携带大量的信息，所以GSM时隙可以分为小时隙，每个小时隙构成会话控制一组移动单元的通道。

摘要： A UE receives HSDPA traffic comprising legacy HSDPA traffic and HS-SCCH-less HSDPA traffic. The UE concurrently processes the received legacy HSDPA traffic and the received HS-SCCH-less HSDPA traffic. The received HSDPA traffic is concurrently buffered into a first storage and a second storage to support simultaneously receiving legacy HSDPA traffic and HS-SCCH-less HSDPA traffic. A HARQ process is performed on the buffered HSDPA traffic in the first storage or the second storage according to a corresponding HS-SCCH CRC test. The resulting HARQ processed HSDPA traffic is Turbo decoded. Turbo decoding on the previously HARQ processed HSDPA traffic is performed simultaneously with HARQ processing on the buffered HSDPA traffic in the first storage or the second storage. The buffered HS-SCCH-less HSDPA traffic is processed via HARQ processing and Turbo decoding for each of the four pre-determined transport formats.
