摘要： A method is provided to allocate resources for wireless communications. The method includes grouping downlink control channels from multiple subframes and ordering the downlink control channels across downlink subframes having a first control channel element located in a first symbol map and associated with reserved resources for an uplink channel. The method employs a symbol first mapping or a mixed-symbol/subframe first mapping to efficiently allocate the resources.

摘要： Techniques for sending control information relating to multiple downlink carriers and data on a single uplink carrier are described. A user equipment (UE) may be scheduled to transmit on a designated uplink carrier. The UE can multiplex control information for multiple downlink carriers with data for transmission on the uplink carrier in a same sub frame. Multiplexing may be performed according to a type of the control information and/or an ordering, priority, or association of the downlink carriers. The UE can selectively encode the control information separately for each downlink carrier and/or jointly across downlink carriers. The control information may be mapped to a single layer or multiple layers of a data channel. The UE may send the multiplexed control information and data on the data channel in the subframe while maintaining a single-carrier waveform.

摘要： Techniques for acknowledging data transmissions in a multi-carrier wireless communication network are disclosed. In one aspect, a UE determines a number of acknowledgement/negative acknowledgement (ACK/NACK) bits for a data transmission on one more component carriers (CCs) based on information obtained from a grant. The grant may be a downlink grant or an uplink grant, and the information obtained may include a number of CCs scheduled for data transmission and/or identifiers of the scheduled CCs. The UE may determine the number of ACK/NACK bits for acknowledging the data transmission based on the number of scheduled CCs and the identifier of each scheduled CC.

摘要： Providing for improved error control signaling in wireless communications is disclosed herein. By way of example, multiple transmissions can be conducted for a HARQ process prior to a scheduled feedback signal on the HARQ process, causing a receiving device to combine the multiple transmissions, rather than treat them as separate transmissions. In this manner, multiple transmissions can be employed to increase overall receive energy, without violating maximum transmit power constraints in a wireless communication. Further, these multiple transmissions can be configured based on prevailing signal strength at the receiving device, or based on processing capabilities of the receiving device, providing flexible protocols that can accommodate advanced as well as legacy UEs in wide range of wireless conditions.
摘要翻译：在此公开了在无线通信中提供改进的差错控制信令。作为示例，可以在HARQ过程上的调度的反馈信号之前对HARQ过程进行多个传输，使得接收设备组合多个传输，而不是将它们视为单独的传输。以这种方式，可以使用多次传输来增加总体接收能量，而不会违反无线通信中的最大传输功率约束。此外，可基于接收设备处的主要信号强度或基于接收设备的处理能力来配置这些多重传输，从而提供灵活的协议，其可在宽范围的无线条件下适应先进的以及传统的UE。

摘要： Techniques for transmitting data and resource signals (RS) are provided. According to certain aspects, an access point may determine RS resource locations related to one or more access points in a CoMP set transmitting a common reference signal (CRS), map data transmissions initially over resources other than those related to the RS resource locations, and map remaining data transmissions over resources related to the RS resource locations. According to certain aspects, a wireless device may receive a signal from access points in a coordinated multiple point (CoMP) communication set comprising a common reference signal (CRS) superimposed over data, determine CRS locations in the signal that correspond to the CRS, and decode data from the signal based at least in part on the determined CRS locations.

摘要： In a wireless communication system, from available data resource elements (REs) in a subframe, REs are assigned to transmissions of a reference signal, thereby resulting in a plurality of remaining data REs. Furthermore, REs from the plurality of remaining data REs are assigned for data transmission to a wireless device in groups of a predetermined number of REs such that all assigned data REs within a group are within a predetermined number of symbols of each other in time domain and within a second predetermined number of subcarriers of each other in frequency domain, thereby resulting in at least one ungrouped RE.

摘要： Techniques for acknowledging data transmissions in a multi-carrier wireless communication network are disclosed. In some aspects, a user equipment (UE) receives a data transmission on at least one component carrier (CC) in a plurality of configured CCs. The UE determines acknowledgement/negative acknowledgement (ACK/NACK) information for the data transmission and determines an uplink channel for sending the ACK/NACK information. When the ACK/NACK information is sent on a PUCCH, the UE may perform power control based on which CCs in the plurality of configured CCs data is received. When the ACK/NACK information is sent on a PUSCH, the UE may determine a number of resource elements based on its CC configuration.

摘要： Systems and methodologies are described that facilitate adaptively communicating data to wireless devices. An access point can precode a dedicated reference signal (DRS) for transmitting to a wireless device, and the wireless device can receive the precoded DRS. The wireless device can determine the precoder by estimating a channel of the DRS and can provide channel condition feedback to the access point. The access point can create data signals including a single or a burst of data transmissions according to the feedback and can precode the data signals using the same precoder. The wireless device can additionally decode the data signals using the precoder. Moreover, the access point can cycle through precoders according to a patterned, random, pseudo-random, and/or similar sequence.
