摘要： Techniques for performing partial cyclic prefix discarding are described. A user equipment (UE) may reduce the amount of cyclic prefix to discard for the last OFDM symbol prior to a switch from data reception to data transmission. This may allow the UE to complete data reception earlier and to switch to data transmission in a timely manner. In one design, the UE may receive a first OFDM symbol and discard a first amount of cyclic prefix for the first OFDM symbol. The UE may then receive a second OFDM symbol and discard a second amount of cyclic prefix for the second OFDM symbol. The second amount of cyclic prefix to discard may be determined based on the amount of time needed to switch from data reception to data transmission, which may be dependent on the amount of time advance between transmit timing and receive timing at the UE.
摘要翻译：描述用于执行部分循环前缀丢弃的技术。在从数据接收切换到数据传输之前，用户设备（UE）可以减少循环前缀的数量以丢弃最后的OFDM符号。这可以允许UE更早地完成数据接收并及时切换到数据传输。在一种设计中，UE可以接收第一OFDM符号并且丢弃用于第一OFDM符号的第一数量的循环前缀。然后，UE可以接收第二OFDM符号并且丢弃用于第二OFDM符号的第二数量的循环前缀。可以基于从数据接收切换到数据传输所需的时间量来确定丢弃的第二量的循环前缀，其可以取决于在UE处的发送定时和接收定时之间的时间推进量。

摘要： Systems and methods allow cell acquisition in a wireless communication system in frequency division multiple access mode of operation. Code sequences transmitted over primary synchronization channel (P-SCH) enable detection of symbol boundary, cyclic prefix duration, and indication of broadcast channel bandwidth. Sequences transmitted over secondary synchronization channel (S-SCH) afford radio frame boundary detection, cell identification, and broadcast channel bandwidth indication. Cell identification can be conveyed jointly between P-SCH and S-SCH codes. Broadcast channel sequences convey cyclic prefix timing, system bandwidth and other system information. Relay of cell acquisition information, as well as multiple-cell acquisition when wireless system operates with frequency reuse are described.

摘要： Multi-carrier point-to-multi-point CDMA system implementation reduces hardware changes in legacy single-carrier systems. The number of common downlink channels, such as timing/synchronization and paging channels, is reduced by designating an anchor carrier for transmitting these channels. Procedures for adding carriers and carrier acquisition are simplified through common carrier timing, signaling by the network to the user equipment (UE) of timing offsets and scrambling code selection, and other measures. Channel reuse is employed to minimize changes in asymmetric systems with different numbers of uplink and downlink carriers. Channel Quality Indicator (CQI) field is divided into multiple subfields to enable transmission of multiple CQIs and ACK/NACK indicators on one uplink carrier. Joint and separate scheduling schemes are shown for concurrent scheduling of a data stream transmission to a UE via multiple downlink carriers.

摘要： Systems, methodologies, and devices are described that facilitate transmitting a guard time parameter to a mobile device to facilitate rate matching data around a guard time region associated with a downlink subframe of a radio frame sequence. A base station transmits the guard time parameter via PBCH or DBCH to the mobile device. The base station rate matches data associated with PDSCH, comprising DBCH, around the guard time region, and transmits PDSCH to the mobile device. The mobile device identifies the guard time parameter and rate matches at least a portion of the information received via the PDSCH around the guard time region to facilitate enhanced reception of PDSCH. Optionally, a radio frame sequence can be structured so that a subframe immediately following a subframe containing DBCH is a downlink subframe, which can be known by the mobile device a priori or based on a downlink subframe parameter.

摘要： Techniques for transmitting and receiving data in an efficient manner to potentially improve capacity for a wireless network and achieve power savings for a wireless device are described. The techniques utilize a Continuous Packet Connectivity (CPC) mode comprised of multiple (e.g., two) discontinuous transmission (DTX) modes and at least one (e.g., one) discontinuous reception (DRX) mode. Each DTX mode is associated with different enabled uplink subframes usable for transmission from the wireless device to the network. Each DRX mode is associated with different enabled downlink subframes usable by the network for transmission to the wireless device. The wireless device may send signaling and/or data on the enabled uplink subframes and may receive signaling and/or data on the enabled downlink subframes. The wireless device may power down during non-enabled subframes to conserve battery power. Mechanisms to quickly transition between the DTX and DRX modes are described.

摘要： Techniques for supporting synchronization in wireless communication are described. A Node B generates a primary synchronization code (PSC) having a length of L chips based on a first inner sequence and a first outer sequence, where L is less than 256. The Node B also generates a sequence of secondary synchronization codes (SSCs) based on a second inner sequence and a second outer sequence, with each SSC having a length of L chips. L may be equal to 64, and the PSC and SSCs may have lengths of 64 chips. The Node B sends the PSC in each slot of each frame and sends the sequence of SSCs in each frame, one SSC in each slot. A user equipment (UE) detects for the PSC and then detects for the sequence of SSCs using slot timing from the PSC detection. The UE may perform PSC detection using correlation results for the SSCs.

摘要： System(s) and method(s) are provided for transmitting data code symbols and control code symbols spanning disparate transmission time intervals in the uplink. Data and control symbols that overlap in time-domain within a transmission time interval are multiplexed and transmitted employing resources scheduled for data transmission, whereas data and control code symbols that are not multiplexed are transmitted in respective allocated resources. Multiplexing in conjunction with localized and distributed resource scheduling preserves the single-carrier characteristics of a single-carrier frequency division multiple access system.
