摘要： In an encoding apparatus in a mobile communication system using a plurality of antennas, a puncturer punctures input coded bits in an RCP (Rate-Compatible Puncturing) method, a distributor divides the punctured coded bits by the number of the antennas depending on how many bits are punctured, an interleaver interleaves the divided coded bits, a modulator modulates the interleaved coded bits, and an arranger prioritizes the modulated symbols, arranges the modulated symbols according to priority levels, and transmits the arranged symbols through the antennas.

摘要： A user equipment (UE) operating in a communication system comprising a base station and one or more UEs. The UE may be configured to operate on or “camp” on two different networks with one radio. In this exemplary system, the radio may be normally connected to the first network (NW1) and may from time to time be “tuned away” from NW1 to a second network (NW2). The UE may inform NW1 that it has tuned away to another network, e.g., using start and end indicators. This information may prevent NW1 from wasting downlink capacity by unnecessarily allocating downlink resources to the UE during the tune-away. Alternatively, or in addition, this information may prevent NW1 from penalizing the UE, e.g., by reducing its future downlink allocations, since the UE does not respond to NW1 commands during the tune-away.

摘要： A user device receives packets from a base station. The user device may invoke decoding while the packet is still being received, based on the incomplete contents of a given packet. This “partial packet decoding” relies on the fact that the underlying information in the packet is encoded with redundancy (code rate less than one). If link quality is poor, the partial packet decoding is likely to be unsuccessful, i.e., to fail in its attempt to recover the underlying information. To avoid waste of power, the user device may be configured to apply one or more tests of link quality prior to invoking the partial packet decoding on a current packet.
摘要翻译：用户设备从基站接收分组。基于给定分组的不完整内容，用户设备可以在分组仍在接收时调用解码。这种“部分分组解码”依赖于以冗余（代码率小于1）对分组中的底层信息进行编码的事实。如果链路质量差，则部分分组解码可能不成功，即在尝试恢复基础信息时失败。为了避免浪费电力，用户设备可以被配置为在对当前分组调用部分分组解码之前应用一个或多个链路质量测试。

摘要： A mobile wireless device adapts receive diversity during discontinuous reception based on downlink signal quality, page indicators and page messages. When the downlink signal quality exceeds a pre-determined threshold, the mobile wireless device decodes a page indicator channel through an initial antenna, and otherwise, decodes a paging channel through the initial antenna without decoding the page indicator channel. The mobile wireless device switches to decoding the paging channel through an alternate antenna when a page indicator decodes as an erasure. When a paging message received through a single antenna decodes with an incorrect error checking code, the mobile wireless devices enables receive diversity through multiple antennas for subsequent decoding. The mobile wireless device switches between single antenna reception and multiple antenna reception based on tracking multiple consecutive error checking code failures and successes.

摘要： Methods and apparatus for synchronizing operational state during hybrid network operation. In one embodiment, the various access technologies that makeup the hybrid network not fully synchronized. Thus, a wireless device operating in a mixed mode must be capable of managing synchronization across multiple access technologies. The wireless device is configured to estimate an expected “tune-away” period when disengaging with a one access technology to address events (for example, link maintenance, calls, data, and the like) or perform monitoring on a second access technology. The estimate is then used by the device to adjust its operational parameters on the technology from which it is tuning away. This ensures smooth switching away from and back to the various network technologies.

摘要： A soft-bit de-mapping device and method of generating soft bits for decoding quantizes a log-likelihood ratio (LLR) value for a received value using functions bits and channel parameter bits to generate the soft bits. The function bits are generated by quantizing an LLR function for the received value, which includes modifying an original curve of the LLR function to a modified curve such that a segment of the original curve with the lowest slope is protected in the modified curve for a fixed equal quantization step-size. The channel parameter bits are generated by quantizing a channel parameter for the received value to generate channel.

摘要： An apparatus and method for canceling interference in an OFDM system using multiple antennas, where based on error estimation of a symbol received from a receive antenna, the error of a symbol received from another receive antenna is estimated. Prior to transmission, symbols to be transmitted through a plurality of transmit antennas are shifted by a predetermined number of bits without overlapping. Thus, the effects of an error of a symbol received from a receive antenna on error estimation of a symbol received from another receive antenna are reduced.

摘要： A method is disclosed for coordinating a user equipment's communication with a network during tune back with C-DRX (connected mode discontinuous receive). When a user equipment tunes back to a network after a tune away or a signal fade, a scheduling request is sent to the network to indicate the tune back as quickly as possible. The user equipment waits for a downlink transmission from the network. When the user equipment does not receive the downlink transmission, the method determines if the connection between the user equipment and the network has been released. The sending of the first scheduling request and any additional scheduling requests is coordinated with the C-DRX configuration so as to maximize the battery savings of C-DRX and minimize the latency of the tune back process in case the user equipment has uplink data to send.

摘要： Electronic devices may be provided that contain wireless communication circuitry. The wireless communication circuitry may include radio-frequency transceiver circuitry coupled to multiple antennas. An electronic device may alternate between a sleep mode and a wake mode. During wake mode, the electronic device may monitor a paging channel in a wireless network for incoming paging signals. The device may use a selected one of the multiple antennas in monitoring the paging channel. If received signal quality is satisfactory, the device may maintain use of the selected one of the multiple antennas for subsequent wake period monitoring of the paging channel. If received signal quality falls below a threshold or is otherwise indicated to not be satisfactory, the device may switch to use of a different one of the multiple antennas in monitoring the paging channel. Other criteria may also be used in controlling the switching between antennas for paging channel monitoring.
