摘要： Apparatus and methods, in one or more aspect, provide feedback with respect to downlink grant feedback communications received by a user equipment (UE). The apparatus and methods monitor for signals from a network entity on one or more channels, and determine, based on the monitoring, whether one or more grants are received and whether UE data is received on the one or more channels. Further, the apparatus and methods generate a feedback indication having a feedback value determined according to a feedback rule and based on whether the one or more grants and the UE data are received. Additionally, the apparatus and methods transmit the feedback indication to the network entity on a resource determined according to the feedback rule and based on whether the one or more grants and the UE data are received.

摘要： Techniques for performing partial cyclic prefix discarding are described. A user equipment (UE) may reduce the amount of cyclic prefix to discard for the last OFDM symbol prior to a switch from data reception to data transmission. This may allow the UE to complete data reception earlier and to switch to data transmission in a timely manner. In one design, the UE may receive a first OFDM symbol and discard a first amount of cyclic prefix for the first OFDM symbol. The UE may then receive a second OFDM symbol and discard a second amount of cyclic prefix for the second OFDM symbol. The second amount of cyclic prefix to discard may be determined based on the amount of time needed to switch from data reception to data transmission, which may be dependent on the amount of time advance between transmit timing and receive timing at the UE.
摘要翻译：描述用于执行部分循环前缀丢弃的技术。在从数据接收切换到数据传输之前，用户设备（UE）可以减少循环前缀的数量以丢弃最后的OFDM符号。这可以允许UE更早地完成数据接收并及时切换到数据传输。在一种设计中，UE可以接收第一OFDM符号并且丢弃用于第一OFDM符号的第一数量的循环前缀。然后，UE可以接收第二OFDM符号并且丢弃用于第二OFDM符号的第二数量的循环前缀。可以基于从数据接收切换到数据传输所需的时间量来确定丢弃的第二量的循环前缀，其可以取决于在UE处的发送定时和接收定时之间的时间推进量。

摘要： A computationally efficient method and apparatus for estimating the bandwidth of a received signal. In an exemplary implementation, signal power within several selectably narrow frequency bands, each centered about a selected frequency, are calculated using only a relatively small number of arithmetic operations. Applications include using the estimated bandwidth to estimate the relative velocity between the transmitter and receiver, and modifying receiver operation based on such estimate.

摘要： In an antenna diverstiy environment, the timing offset of the receiver's fingers are based on the timing offset of the received peaks of the base station transmit signals. In a system with non-neglible multipath spacing, the timing offset of the received peaks of the base station transmit signals are not necessarily at the same location. In one embodiment, the demodulating elements for the signal from each base station antenna use the same offset for demodulating and determining an error signal based on pilot signal sampling prior to the timing offset and subsequent to the timing offset. The error signals are averaged and used by a time trackin loop to track the incoming signal. In another embodiment, the demodulating elements for the signal from each base station antenna independently time track the signals with different times offsets for each finger. The preferred embodiment depends on the method used by the base station to multiplex the data onto multiple transmit antennas.
摘要翻译：在天线分叉环境中，接收机手指的定时偏移基于基站发射信号的接收峰值的定时偏移。在具有不可忽略的多路径间隔的系统中，基站发射信号的接收峰值的定时偏移不一定在相同的位置。在一个实施例中，用于来自每个基站天线的信号的解调元件使用相同的偏移量来解调和确定基于在定时偏移之前和定时偏移之后的导频信号采样的误差信号。误差信号被平均化，并被时间跟踪环路用于跟踪输入信号。在另一个实施例中，用于来自每个基站天线的信号的解调元件独立地对每个手指的不同时间偏移量跟踪信号。优选实施例取决于基站用于将数据复用到多个发射天线上的方法。

摘要： The present disclosure may enable a buffer to accommodate HARQ processes for transmissions with different TTIs when the UE is configured for legacy communications and ULL communications. The apparatus may allocate a first number of HARQ IDs to a first portion of a buffer, the first number of HARQ IDs being associated with a first transmission TTI HARQ process. In addition, the apparatus may allocate a second number of HARQ IDs to a second portion of the buffer. In an aspect, the second number of HARQ IDs may be associated with a second TTI HARQ process. In addition, the first portion and second portion may not change a total buffer size. The apparatus may also receive a HARQ response associated with a HARQ ID allocated to the first portion or the second portion.

摘要： Standalone MBSFN cells may provide an improved user experience for an individual with a non-legacy UE since the bandwidth of that cell is mostly allocated to broadcasting streaming services. However, an individual with a legacy UE may be able to detect cell acquisition information associated with a standalone MBSFN cell but not to acquire standalone MBSFN cells. In order to solve this problem, the present disclosure provides various UE avoidance schemes that enable non-legacy UEs to acquire a standalone MBSFN cell and prevents legacy UEs from trying to acquire a standalone MBSFN only cell. The apparatus may receive cell acquisition information associated with an eMBMS standalone cell. The apparatus may detect a UE avoidance scheme based on a characteristic associated with the cell acquisition information. The apparatus may perform cell acquisition with the eMBMS standalone cell based on the characteristic.

摘要： Certain aspects relate to methods and apparatus for latency reduction for UEs in a RRC connected mode. During contention-based uplink access by groups of UEs within a subframe, an eNB may decode the received uplink transmission based, at least in part, on the assigned group of resources assigned to the UE and used for transmission. Additional orthogonalization techniques such as reduced TTI size can be used to reduce collisions among different users performing contention-based transmissions. Furthermore, when the eNB fails to successfully decode the uplink transmission, the eNB may identify the UE that sent the uplink transmission based on a detected reference signal and may transmit an uplink assignment to the identified UE.

摘要： For frequency bin error estimation, multiple hypotheses are formed for different frequency bin errors, pilot offsets, or combinations of frequency bin error and pilot offset. For each hypothesis, received symbols are extracted from the proper subbands determined by the hypothesis. In one scheme, the extracted received symbols for each hypothesis are despread with a scrambling sequence to obtain despread symbols for that hypothesis. A metric is derived for each hypothesis based on the despread symbols, e.g., by deriving a channel impulse response estimate based on the despread symbols and then deriving the metric based on the channel impulse response estimate. In another scheme, the extracted received symbols for each hypothesis are correlated, and a metric is derived based on the correlation results. For both schemes, the frequency bin error and/or the pilot offset are determined based on the metrics for all hypotheses evaluated.

摘要： A pilot searcher for CDMA and GPS signals. In one aspect, the searcher is operated in conjunction with a sample buffer in a "real-time" or "off-line" mode. The writing/reading of samples to/from the buffer may be performed in a TDM manner via a common port, and samples may be decimated and packed prior to storing in the buffer. In another aspect, the overall search for pilots is partitioned into a number of tasks, with each task corresponding to a search over a given sample segment and based on a particular set of parameter values. The tasks may be stored in a queue and performed one at a time based on their order in the queue. Prior to performing a new task, the parameter values for that task is downloaded to a set of configuration registers. The parameters may be ordered and linked such that only new values are downloaded.
