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： Systems and methodologies are described that facilitate allocation of uplink acknowledgement (ACK) resources for a wireless communication system. Various aspects described herein facilitate explicit creation and transmission of a bundled assignment of downlink communication resources and uplink resources for ACK transmission, thereby facilitating overhead-efficient ACK allocation for users that can communicate pursuant to a persistent resource assignment without requiring scheduling information from an associated control channel. Additionally, indexing schemes for uplink ACK resources are provided herein to facilitate ACK allocation for systems in which both scheduled and persistent users can communicate at a common transmission time interval (TTI).

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： A method for enhancing a sounding reference signal (SRS) in a non-root wireless communication device is disclosed. The method determines that all SRS transmissions for the wireless communication device are to occur in an uplink pilot time slot (UpPTS) portion of a transition subframe. The method also determines whether available uplink bandwidth for the UpPTS portion is greater than available uplink bandwidth for a normal uplink subframe. A current SRS is transmitted using the available uplink bandwidth for UpPTS portion when the available uplink bandwidth for the UpPTS portion is greater than available uplink bandwidth for the normal uplink subframe.

摘要： Techniques for sending control information in a wireless communication system are described. A user equipment (UE) may be configured to periodically send control information (e.g., CQI information) and may receive an assignment of control resources for sending the control information. The UE may also receive an assignment (e.g., a dynamic assignment or a semi-persistent assignment) of data resources for sending data. The UE may send the control information (i) on the control resources if the control and data resources do not coincide in time or (ii) on a designated portion of the data resources if the control and data resources coincide in time. The UE may generate at least one SC-FDMA symbol with the control information sent on the control resources or the designated portion of the data resources. The UE can maintain a single-carrier waveform for each SC-FDMA symbol.

摘要： Systems and methodologies are described that facilitate adaptive uplink pilot multiplexing schemes. In various embodiments, frequency position and pilot channel bandwidth can be adaptively varied in a block over time based on the uplink channel data, such as the number of streams to be multiplexed. Thus, the provided adaptive uplink pilot multiplexing schemes provide flexible uplink pilot allocation schemes while maintaining single carrier waveform for improved transmit power efficiency and orthogonality of pilots within blocks for improve channel estimation and suppression of interference.

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：本文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过程之前的调度的反馈信号之前对HARQ进程进行多个传输，使得接收设备组合多个传输，而不是将其作为单独的传输。以这种方式，可以采用多个传输来增加总体接收能量，而不违反无线通信中的最大发射功率约束。此外，可以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个传输，从而提供可在宽范围的无线条件下适应高级以及传统UE的灵活协议。
