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： 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。

摘要： Systems and methodologies are described that facilitate multiplexing of control information and data for common transmission in a localized FDM wireless communication system. Localized FDM transmission of control and data channels can be achieved by, for example, multiplexing control information with data and transmitting the control information and data using resources and transmission schemes specified for transmission of the data. To ensure the reliability of control information multiplexed with data, a power offset can be applied to the control information to provide varying protection levels for the control information based on properties of the data resources into which it is embedded in order to maintain a predetermined signal quality for the control information independent of the data resources.

摘要： Systems and methodologies are described that facilitate selecting frequency for transmitting control channel format indicator (CCFI) data such to identify a related cell. In one example, the CCFI data can be transmitted in an initial portion of frequency (such as an orthogonal frequency division multiplexing (OFDM) symbol) in a time transmit interval (TTI). The CCFI data can be spread across the initial portion of frequency and be shifted to identify the transmitting cell. Additionally, the CCFI data can be scrambled to further identify the cell. The CCFI data can also be utilized to determine structure of subsequent control and/or data channels.

摘要： Techniques for sending feedback information for multi-carrier operation are described. In an aspect, feedback information may be sent on an uplink carrier that may or may not be paired with a downlink carrier on which data transmission is sent. A user equipment (UE) may receive data transmission on a downlink carrier among a plurality of downlink carriers. The UE may determine feedback information for the data transmission, determine an uplink carrier to use to send the feedback information from among a plurality of uplink carriers, and send the feedback information on the uplink carrier. In another aspect, feedback information for multiple downlink carriers may be sent on at least one uplink carrier using Single-Carrier Frequency Division Multiple Access (SC-FDMA). A UE may receive data transmissions on a plurality of downlink carriers, determine feedback information for the data transmissions, and send the feedback information on at least one uplink carrier using SC-FDMA.
