摘要： There is provided a communication device and a base unit, and methods thereof, for determining control information. The communication device receives a control channel message associated with the communication device in a control region on a first carrier from a base unit. The communication device also determines a set of resources in a search space within the control region, attempts to decode the set of resources in the search space for the control channel message, and determines control information from the decoded control channel message. The base unit generates a control channel message comprising control information associated with the communication device, determines a set of resources in a search space within a control region, selects a subset of resources within the determined set of resources for transmitting the control channel message, and transmits the control channel message on the selected resources in the control region on a first carrier.

摘要： A joint soft output ML receiver that is able to reduce interference based on partial transmission information (i.e., without knowing the existence of other layers or other users and their modulation schemes) is described. In one implementation, the partial information based joint ML receiver can achieve performance that is similar to full information based joint ML receivers even when full information regarding the interfering UE is not available at the desired UE due to transparent Multi-user Multiple Input and Multiple Output (MU-MIMO) transmission (such as with TM 8 and TM 9 transmissions in EUTRA LTE).
摘要翻译：描述了能够基于部分传输信息（即，不知道其他层或其他用户的存在及其调制方案）来减少干扰的联合软输出ML接收器。在一个实现中，由于透明的多用户多输入和多输出，即使关于干扰UE的全部信息在期望的UE处不可用，基于部分信息的联合ML接收机也可以实现类似于基于全信息的联合ML接收机的性能（MU-MIMO）传输（例如在EUTRA LTE中使用TM8和TM9传输）。

摘要： A wireless communication terminal that has the self-interference due to the support of carrier aggregation, aggregating and jointly using two or more component carriers for transmission and reception, performs a first set of measurements on a received signal on a first operating frequency, wherein the first set of measurements are performed during which the wireless terminal transmits or receives signals on a second operating frequency. In an alternative embodiment, the wireless communication terminal changes the maximum transmit power limit on a first operating frequency on a per-slot basis to reduce the impact of harmonic or intermodulation distortion on a received signal at a second operating frequency.

摘要： A wireless communications system base station (101), upon receiving (202) from a mobile station (102) a wireless transmission that comprises a suggested transmitter-receiver configuration, can respond (in appropriate instances) by automatically transmitting (203) to the mobile station a wireless transmission comprising an indication to use instead a default transmitter-receiver configuration. By one approach, the latter action can be based, at least in part, upon a determination regarding reliability (301) of that suggested transmitter-receiver configuration (which might comprise, for example, a direct or indirect measure of quality of the channel by the default transmitter-receiver configuration was received) to provide a corresponding reliability assessment. The latter can then be used (302) to determine whether to use this suggested transmitter-receiver configuration for a subsequent communication with the mobile station.

摘要： A method and apparatus for performing resource allocation with lower required overhead is provided herein. Resource allocations for data transmissions are chosen in such a way as to provide channel quality information for various parts of the channel bandwidth (frequency selective channel quality information), such as allocating two different resource blocks (on different sets of subcarriers) to a mobile unit for two different transmissions. These data transmissions are used to estimate frequency selective channel quality information, thereby eliminating or greatly reducing the need for channel sounding with a broadband pilot. As a result, the overhead on the uplink of the communication system may be significantly reduced.

摘要： A method and system for adaptive control of sub-carriers is useful for increasing frequency diversity gain to improve bit error rate performance in an Interleaved Frequency Division Multiple Access (IFDMA) system. The method includes selecting a combination of a Repetition Factor (RF) and a repetition block size (Q), from possible combinations of a RF and a Q, based on a number of users (Nu) (step 1405). A Spreading Factor (SF), Forward Error Correction (FEC) coding rate (R), or modulation order (M) based on the Nu is then determined (step 1410). Control signals are then provided based on the RF and Q, and based on the SF, R, or M (step 1415).

摘要： In an OFDM system the same Walsh code is used at the same time for a plurality of transmitters. The multiple transmitters can be from the same, or different devices (e.g., different base stations on the downlink, different terminals on the uplink). Each subcarrier/antenna combination will share a similar pilot Walsh code, except for the fact that the scrambled spread pilot signals will be phase shifted on some subcarriers of some antennas, based on the subcarrier/antenna combination.
