摘要： Aspects relate to a flexible interleaving scheme that provides frequency diversity to randomizes interference Frequency diversity groups can be utilized, wherein control channel elements (CCEs) gain greater frequency diversity for a given number of mini-CCEs (e.g., subset of CCEs). A frequency diversity group index is permuted according to a bit reversed scheme to facilitate control channel elements with a small number of mini-CCEs to also gain sufficient frequency diversity.

摘要： Supporting communication on multiple carriers. A user equipment (UE) is configured with a base (anchor, regular, stand-alone) carrier and a dependent (extension) carrier linked (paired) to the base carrier. Data transmission on the dependent carrier is scheduled via a scheduling carrier, which is different from the dependent carrier. The UE receives (714) a scheduling grant on the scheduling carrier and determines whether the scheduling grant is for the base carrier and/ or the dependent carrier. The UE communicates (718), e.g. sends or receives data, on the base carrier and/or the dependent carrier based on the scheduling grant. The scheduling grant may be (i) a separate grant carrying scheduling information for only one carrier, (ii) a common grant carrying scheduling information for both carriers, (iii) a joint grant carrying separate scheduling information for each carrier, or (iv) a composite grant that may be a separate grant, a common grant, or a joint grant. A configuration of the base (anchor) carrier and a dependent (extension) carrier is received from the eNodeB at the UE.

摘要： Techniques for performing decision feedback equalization are described. A feed-forward filter response and a feedback filter response are derived based on a channel estimate and a reliability parameter and further without constraint on the feedback filter response or with a constraint of no feedback for an on-time sample. The reliability parameter is indicative of the reliability of the feedback used for equalization and may be frequency dependent or frequency invariant. Different feed-forward and feedback filter responses may be derived with different constraints on the feedback filter and different assumptions for the reliability parameter. Equalization is performed with the feed-forward and feedback filter responses. If equalization is performed for multiple iterations then, for each iteration, the reliability parameter may be updated, the feed-forward and feedback filter responses may be derived based on the updated reliability parameter, and equalization may be performed with the filter responses for the iteration.
摘要翻译：描述用于执行判决反馈均衡的技术。基于信道估计和可靠性参数导出前馈滤波器响应和反馈滤波器响应，并且进一步而不受反馈滤波器响应的约束或者对于准时采样没有反馈的约束。可靠性参数表示用于均衡的反馈的可靠性，并且可以是频率依赖的或频率不变的。不同的前馈和反馈滤波器响应可以通过反馈滤波器的不同约束和可靠性参数的不同假设得出。使用前馈和反馈滤波器响应执行均衡。如果对多次迭代执行均衡，那么对于每个迭代，可以更新可靠性参数，可以基于更新的可靠性参数导出前馈和反馈滤波器响应，并且可以用迭代的滤波器响应来执行均衡。

摘要： An equalization filter is provided with the ability to softly switch between pure linear equalization and decision feedback equalization. A reliability gain factor and an associated gain factor calculated by a predetermined mapping relation are provided in a decision feedback path and a feedforward path, respectively. Increasing the reliability gain factor increases the significance of the decision feedback filtering. Better performance than pure linear equalization and pure decision feedback equalization can be achieved.

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.

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.

Wireless devices can receive control region parameters related to the carriers or CoMP access points from a serving access point over control channel resources. Additionally or alternatively, wireless devices can assume all carriers or CoMP access points have substantially the same control region as indicated in a control format indicator channel from the serving access point or based on a configured value.

摘要： Systems and methodologies are described that facilitate employing circular buffer based rate matching. Encoded block(s) that include systematic, parity 1, and parity 2 bits can be generated using turbo code. Bit type can be identified to separate bits into distinct groups. Systematic bits can be interleaved together to generate a randomized sequence of systematic bits, parity 1 bits can be interleaved together to yield a randomized sequence of parity 1 bits, and parity 2 bits can be interleaved together to output a randomized sequence of parity 2 bits. The randomized sequences of parity 1 bits and parity 2 bits can be interlaced together in an alternating manner. The randomized sequence of systematic bits can be inserted into a circular buffer, and upon inserting the entire sequence, the interlaced parity bits can be inserted into the circular buffer (e.g., until reaching capacity). Bits inserted into the circular buffer are transmitted.
