Abstract: A receiver generates an unmapped symbol encoded according to a symbol constellation in a received signal. The receiver may determine whether a bit value constituting bits of the unmapped symbol is known a priori, and generates a de-mapped symbol representation for the unmapped symbol from a sub-region of a constellation map constrained by the bit value, if the bit value is known. As a result, errors introduced by the transmission channel may be reduced with less processing.
Abstract translation: 接收器生成根据接收信号中的符号星座图编码的未映射符号。 接收器可以确定构成未映射符号的比特的比特值是否先验已知，并且如果比特值被限制，则从由比特值约束的星座映射的子区域产生未映射符号的解映射符号表示 已知。 结果，传输通道引入的错误可能会减少处理。

Abstract: A base station may provide both an uplink grant and a downlink grant in a same transmission time interval (TTI), and may provide an indication in the uplink grant that the TTI includes the downlink grant. A user equipment (UE) that receives the uplink grant may provide feedback using identified feedback resources in an uplink shared channel, and other uplink transmissions may be rate matched around the feedback resources in the uplink shared channel. A base station receiving the feedback may monitor the feedback resources to determine whether the downlink grant or one or more of the downlink transmissions were successfully received at the UE. A base station, in some examples, may monitor different sets of resources to determine whether certain of the uplink grant, downlink grant, downlink transmissions associated with the downlink grant, or any combinations thereof, have been successfully received at the UE.

Abstract: A method for and apparatus for transmitting and receiving data in a wireless communication system supporting multiple carriers is provided. A wireless device determines a starting OFDM symbol of a physical downlink shared chancel (PDSCH) which is variably located by presence of reference signal (RS), a number of physical resource block(PRB)s used for an enhanced physical downlink control channel (ePDCCH), and receives the ePDCCH. The ePDCCH is set by one or more sets of PRBs within the PDSCH configured for a UE to monitor the ePDCCH. Thus, more efficient and accurate scheduling with lower complexity and reduction of control overhead of a master cell (as PCell), for multi-UEs and variable control information transmissions are supported in this invention.
Abstract translation: 提供了一种用于在支持多个载波的无线通信系统中发送和接收数据的方法和装置。 无线设备确定通过存在参考信号（RS）可变地定位的物理下行链路共享机会（PDSCH）的起始OFDM符号，用于增强物理下行链路控制信道（ePDCCH）的物理资源块（PRB） ），并接收ePDCCH。 ePDCCH由配置用于监视ePDCCH的UE配置的PDSCH内的一个或多个PRB集合来设置。 因此，在本发明中支持用于多UE和可变控制信息传输的较低复杂度和降低主小区（如PCell）的控制开销的更有效和准确的调度。

Abstract: An apparatus may receive a set of configurations for an EPDCCH that are tied (linked) to a set of configurations received for a PDSCH (they may be a subset of the set of PDSCH configurations). The apparatus may then receive and process the EPDCCH based on at least one configuration from the set of configurations for the EPDCCH In another aspect, the apparatus may determine at least a first and second resource set configured for a control channel (e.g. EPDCCH) and may determine a common set of aggregation levels for the first and second resource sets. The apparatus may further determine first rate-matching parameters for the first resource set and second rate- matching parameters for the second resource set, and may process the control channel using the common set of aggregation levels and the first and second rate-matching parameters. In another aspect, the apparatus determines whether a starting symbol of an enhanced physical downlink control channel (EPDCCH) is an initial symbol (i.e. its value is zero) in a subframe based on an EPDCCH configuration and refrains from decoding a subset of legacy control channels in the subframe when the starting symbol of the EPDCCH is the initial symbol in the subframe.
