摘要： Resource mapping and coding schemes to handle bursty interference are disclosed that provide for spreading the modulated symbols for one or more transmission code words over more symbols in the time-frequency transmission stream. Certain aspects allow for the modulated symbols to be based on bits from more than one code word. Other aspects also provide for re-mapping code word transmission sequences for re-transmissions based on the number of re-transmissions requested by the receiver. Additional aspects provide for layered coding that uses a lower fixed-size constellation to encode/decode transmissions in a layered manner in order to achieve a larger- size constellation encoding. The layered encoding process allows the transmitter and receiver to use different coding rates for each coding layer. The layered encoding process also allows interference from neighboring cells to be canceled without knowledge of the actual constellation used to code the interfering neighboring signal.
摘要翻译：公开了用于处理突发干扰的资源映射和编码方案，其用于在时间 - 频率传输流中通过更多符号将一个或多个传输码字的调制符号扩展。某些方面允许调制符号基于来自多于一个码字的比特。其他方面还提供了基于由接收机请求的重传次数来重新映射用于重传的码字传输序列。另外的方面提供了使用较低固定尺寸星座以分层方式对传输进行编码/解码以便实现更大尺寸星座编码的分层编码。分层编码过程允许发射机和接收机对每个编码层使用不同的编码速率。分层编码处理还允许在不知道用于对干扰相邻信号进行编码的实际星座的情况下取消来自相邻小区的干扰。

摘要： Systems and methods providing an enhanced new carrier type (eNCT) operable to adapt cells of a wireless communication network for opportunistic behavior that adapts to the geo-temporal traffic distribution are disclosed. Embodiments of eNCT operation provide for transmission of downlink common channels by cells employing eNCT techniques only when needed. Base stations implementing eNCT techniques herein may transition between two or more operational states, such as an active state wherein full base station functionality is performed and a dormant state wherein limited base station functionality is performed, based upon geo-temporal traffic distribution within the network. Thus, when a base station is not actively serving a user equipment (UE), the downlink transmission by the base station, and resulting interference, may be reduced or even eliminated.

摘要： Systems and techniques are disclosed to reduce pilot overhead by providing common reference signals coded with cover codes that are orthogonal in time and frequency domains. Common reference signals that are coded by cover codes orthogonal in both domains can be de-spread in both the time and frequency domains for improved resolution and larger pull-in windows. Semi-uniform pilot spacing in both the frequency and time domains can be utilized. In time domain, a first pilot symbol pair is spaced by a first time interval and a second pilot symbol pair is spaced by a second time interval from the first pair, the second interval being greater than the first. In frequency domain, a first set of pilot symbols is densely placed in a selected frequency band and a second set of pilot symbols is sparsely placed surrounding and including the selected frequency band.

摘要： Systems and techniques are disclosed to enhance the efficiency of available bandwidth between UEs and base stations. A UE transmits a sounding reference signal to the base station, which characterizes the uplink channel based on the SRS received and, using reciprocity, applies the channel characterization for the downlink channel. The base station may form the beam to the UE based on the uplink channel information obtained from the SRS. As the downlink channel changes the base station needs updated information to maintain its beamforming, meaning it needs a new SRS. Transmission of the SRS takes resources; to minimize this, the UE or the base station can determine a period during which the downlink channel will predictably remain coherent and set up a schedule for sending SRS. Alternatively, the UE or the base station can determine on demand that the channel is losing coherence and initiate an on demand SRS.
