摘要： Methods, systems, and devices are described for wireless communication. Wireless devices may exchange data using Medium Access Control (MAC) layer units known as transport blocks. The transport blocks may be partitioned into code block clusters (CBCs), each of which may include one or more code blocks. A receiving device may attempt to decode a transport block and send acknowledgement (ACK) and negative-acknowledgment (NACK) information to the transmitting device based on the whether each CBC was successfully decoded. The transmitting device may retransmit a redundancy version of a CBC for each NACK received. The transmitting device may group CBCs in segments of a transport block according to redundancy version. In some cases, the transmitting device may send a control message in a control channel which indicates the composition of the transport block.

摘要： Techniques are provided for reduction of processing requirements for portions of a received transmission relative to processing requirements for other portions of the same transmission. Different coding schemes may be employed for portions of a data transmission. In some examples, a tail portion of a data transmission may use a coding scheme that had reduced processing requirements relative to other portions of the data transmission. The reduced processing requirements may allow a receiver to generate an acknowledgment of receipt relatively quickly, which may reduce latency for acknowledging receipt of a transmission.
摘要翻译：提供了相对于相同传输的其他部分的处理要求来减少接收的传输的部分的处理要求的技术。不同的编码方案可以用于数据传输的部分。在一些示例中，数据传输的尾部可以使用相对于数据传输的其他部分具有减少的处理要求的编码方案。减少的处理要求可以允许接收机相对快速地生成接收确认，这可以减少用于确认传输的接收的等待时间。

摘要： A method for communicating in an advanced long term evolution (LTE-A) network using common reference signal (CRS) resources associated with different interference levels due to resource partitioning is disclosed. Signals are received from an eNodeB indicating a subset of CRS resources for radio link monitoring (RLM) and/or reference signal received power (RSRP) measuring. The subset of CRS resources includes the CRS resources expected to have lower interference from the interfering eNodeBs. RLM and/or RSRP measurements are performed based on the indicated subset.

摘要： Obtaining a timing reference in wireless communication is facilitated when desiring to communicate with a weak serving base station (such as an evolved NodeB) in the presence of a stronger interfering base station. The user equipment (UE) may track a stronger interfering base station's timing, or the UE may track a timing that is derived by a composite power delay profile (PDP) from multiple base stations. The composite PDP may be constructed by adjusting individual base station PDPs according to a weighting scheme. The timing obtained in such a manner may be used for estimation of the channel of the interfering base station and cancelling interfering signals from the base station. It may also be used to estimate the channel of the serving base station after adding a backoff. The UE may track a stronger interfering base station's frequency, or the UE may track a composite frequency.

摘要： Estimation of timing errors is disclosed that uses user equipment reference signals (UERSs). A UE models each channel in a user equipment reference signal (UERS) as a channel on an adjacent UERS tone multiplied by a phase ramping term. This phase ramping term is determined using an estimator on the modeled channels. The UE then determines the equivalent timing error by mapping the phase ramping terms into the estimated timing errors in the time domain. In coordinated multipoint (CoMP) systems, the UERS-based timing error may be used to identify an aligned common reference signal (CRS) associated with the network entity transmitting the data. With this determination, the UE may estimate a CRS-based timing error and either substitute the CRS-based timing error for the UERS-based timing error or calculate a further average timing error based on both the CRS-based and UERS-based timing errors.
摘要翻译：公开了使用用户设备参考信号（UERS）的定时误差的估计。 UE将用户设备参考信号（UERS）中的每个信道建模为在相邻UERS音调乘以相位斜变项的信道。该相位斜变项是使用建模通道上的估计器确定的。然后，UE通过将相位斜变项映射到时域中的估计定时误差来确定等效定时误差。在协调多点（CoMP）系统中，基于UERS的定时误差可以用于识别与发送数据的网络实体相关联的对准的公共参考信号（CRS）。通过该确定，UE可以估计基于CRS的定时误差，并且基于用于基于UERS的定时误差替代基于CRS的定时误差，或者基于基于CRS和基于UERS的定时误差来计算另外的平均定时误差。

摘要： Methods, systems, and devices for wireless communications are described. A base station may associate a first port and a second port each with a set of antenna elements based on a first and a second linear precoding vector, where the phases of the ports are coherent. The base station may generate coefficients indicating a first combination and a second combination of a first data set for a first user equipment (UE) and a second data set for a second UE. In some cases, the base station may apply the first linear precoding vector to the first combination, apply the second linear precoding vector to the second combination, and transmit the first combination using a first transmission beam corresponding to the first port and the second combination using a second transmission beam corresponding to the second port to the first and second UEs.

Another aspect may include generating a first reservation preamble of a first operator based on at least one of a compressed representation in a signal space, a basis function of the signal space, or a CAZAC sequences; and transmitting, on a first timeslot of multiple time slots of a downlink channel, the first reservation preamble of the first operator to at least a UE.
