摘要： Techniques for transmitting data using a combination of explicit cyclic delay and implicit cyclic delay are described. A transmitter may perform fir=t processing for cyclic delay diversity (or explicit cyclic delay processing) based on a first set of cyclic delay values known to a receiver. The transmitter may perform precoding based on a precoding matrix either before or after the explicit cyclic delay processing. The transmitter may perform second processing for cyclic delay diversity (or implicit cyclic delay processing) based on a.second set of cyclic delay values unknown to the receiver. The transmitter may perform both explicit and implicit cyclic delay processing for data and may perform only implicit cyclic delay processing for pilot. One entity may. select the first set of cyclic delay values and inform the other entity. The transmitter may autonomously (e.g. pseudo-randomly) select the second set of cyclic delay, values without informing the receiver.

摘要： Facilitating frequency hopping for single carrier, frequency division multiple access (SC-FDMA) transmission is described herein. By way of example, user data transmitted within a transmission allocation unit can be frequency shifted with respect to time based slots of the allocation unit. As a result, frequency hopping can be accomplished while preserving single carrier constraints and a low peak to average power ratio (PAPR). Furthermore, various frequency shifted mechanisms are disclosed to accomplish preservation of single carrier restraints. For example, a scheduler can select between cyclic frequency shifting, transposed frequency shifting, and multiplexing of frequency selective scheduled and frequency hopped data based on an audit of scheduled data for the transmission allocation unit. As a result, the reduction in interference achieved through frequency hopping can be combined with the low PAPR for various data allocation configurations.
摘要翻译：本文描述了单载波，频分多址（SC-FDMA）传输的便利跳频。作为示例，在发送分配单元内发送的用户数据可以相对于分配单元的基于时间的时隙进行频移。因此，可以在保持单载波约束和低峰均功率比（PAPR）的同时实现跳频。此外，公开了各种频移机构来实现单载波约束的保存。例如，调度器可以基于用于传输分配单元的调度数据的审计，在循环频移，转置频移和频率选择性调度和跳频数据的多路复用之间进行选择。结果，通过跳频实现的干扰的减少可以与用于各种数据分配配置的低PAPR组合。

摘要： Techniques for sending control information in a communication system are described. In an aspect, control information may be sent in a first frequency location (e.g., a first set of subcarriers) if data is not being sent and in a second frequency location (e.g., a second set of subcarriers) if data is being sent. In another aspect, control information may be processed in accordance with a first processing scheme if data is not being sent and with a second processing scheme if data is being sent. In one design of the first scheme, a CAZAC sequence may be modulated with each modulation symbol for control information to obtain a corresponding modulated CAZAC sequence, which may be sent on the first set of subcarriers. In one design of the second scheme, modulation symbols for control information may be combined with modulation symbols for data, transformed to frequency domain, and mapped to the second set of subcarriers.

摘要： A method for a wireless communication includes receiving or storing a peak to average (PAR) back off value; and applying the PAR back off value to determine the transmission power and rate for SIMO and MIMO transmissions. In one aspect, the PAR back off value is at least partially based on modulation type. In another aspect, the PAR back off value is more for higher order QAM than for QPSK. The power allocation algorithm for different UL MIMO schemes is described as follows. For MIMO without antenna permutation (e.g. per antenna rate control), different PAR back off values are considered for different data streams. For MIMO with antenna permutation or other unitary transformation such as virtual antenna mapping or precoding, the PAR back off are determined based on combined channel. The transmission data rate depends on power and also the receiver algorithms such as a MMSE receiver or MMSE-SIC receiver.

摘要： Techniques for transmitting acknowledgement (ACK) information in a wireless communication system are described. The system supports data transmission to multiple user equipments (UEs) on the same downlink resources with spatial division multiple access (SDMA). A base station sends a data transmission with multiple (M) layers to M UEs. The downlink resources used for the data transmission are associated with ACK resources used to send ACK information for the data transmission. The ACK resources may be partitioned into M portions, e.g., based on frequency division multiplexing (FDM). Each of the M layers is associated with a respective portion of the ACK resources. A recipient UE for each layer sends ACK for that layer on the associated portion of the ACK resources. For each ACK resource portion, one or more pilot symbols may be sent on one or more resource elements, and ACK symbols may be sent on remaining resource elements.

摘要： Techniques for efficiently deriving uplink channel estimates without consuming much additional uplink resources are described. A user equipment (UE) may send a request for uplink resources on a request channel (REQCH) whenever the UE desires to transmit data on the uplink. The UE may send the REQCH on a set of subcarriers and from multiple antennas, e.g., send REQCH data on data subcarriers and pilot on pilot subcarriers. A Node B may receive the request, estimate the complex channel gains for the pilot subcarriers based on received pilot symbols, and coherently demodulate received data symbols based on the channel gain estimates. The Node B may estimate the complex channel gains for the data subcarriers based on demodulated data symbols and derive a channel estimate for each UE antenna based on the channel gain estimates for the pilot and data subcarriers. The Node B may use the channel estimates for MIMO scheduling, subband scheduling, and rate selection.

摘要： In 3GPP LTE, the uplink ACK and CQI bits are jointly coded prior to transmission to maintain a low peak to average ratio (PAR) waveform. Further, when data needs to be transmitted, the uplink control channels are multiplexed with data prior to transmission. However, due to errors on downlink (DL) and uplink (UL) assignments, an evolved Base Node (eNB) receiver needs to employ a set of rules to decode the control channels, to minimize the number of blind decoding hypotheses. This innovation describes the rules employed by a receiver to reduce complexity and computational overhead in part by assuming that the UE is responding to grant on the download while providing for combinations in which one or more types of grants are not received. Energy detection in accordance with metrics and normalizing for differing power controls enables selecting the correct combination for decoding.
摘要翻译：在3GPP LTE中，上行链路ACK和CQI比特在发送之前被联合编码以保持低的峰值平均比（PAR）波形。此外，当需要发送数据时，将上行链路控制信道与传输之前的数据进行多路复用。然而，由于下行链路（DL）和上行链路（UL）分配上的错误，演进的基站（eNB）接收机需要采用一组规则来解码控制信道，以使盲目解码假设的数量最小化。该创新描述了接收机采用的规则，以部分地通过假设UE在下载时响应授权，同时提供未接收到一种或多种类型的授权的组合，来降低复杂性和计算开销。能量检测按照度量标准化和不同的功率控制标准化，可以选择正确的组合进行解码。
