Abstract: Suppression of serving cell transmissions directed to second-served UEs may improve channel estimation of a serving cell or a neighbor cell. This may include using scheduling information for second-served UEs to suppress serving cell signals intended for second-served UEs having overlapping MIMO transmissions. Alternatively, this scheduling information may aid in suppressing a serving cell signal for a second-served UE to improve channel estimation of a neighbor cell. Various embodiments described herein, include implementations and techniques to aid channel estimation, and signal scheduling information to a first-served UE to aid in suppression of serving cell signals for second-served UEs.

Abstract: An eNB may determine a root for a sequence to be included in a signal to a UE. The eNB may generate a generalized Chu sequence based on the root and scramble the generalized Chu sequence using a pseudorandom sequence that is common to a plurality of eNBs. The eNB may transmit the scrambled generalized Chu sequence to indicate the beginning of a downlink transmission. The UE may receive this scrambled generalized Chu sequence and determine if a beginning of a downlink transmission from a serving eNB based on the received generalized Chu sequence and an expected generalized Chu sequence.

Abstract: Certain aspects of the present disclosure relate to methods and apparatus for network assisted interference cancellation (IC) and interference suppression (IS) for multiple services. According to aspects a user equipment (UE) may determine information regarding system parameters for one or more types of communications services used to transmit potentially interfering signals in one or more neighbor cells, wherein a type of the information determined depends on the type of communications service. The UE may perform interference management using the determined information to cancel or suppress interference caused by the potentially interfering signals.
Abstract translation: 本公开的某些方面涉及用于多个服务的网络辅助干扰消除（IC）和干扰抑制（IS）的方法和装置。 根据方面，用户设备（UE）可以确定关于用于在一个或多个相邻小区中发送潜在干扰信号的一种或多种类型的通信服务的系统参数的信息，其中确定的信息的类型取决于通信服务的类型 。 UE可以使用确定的信息来执行干扰管理以消除或抑制由潜在干扰信号引起的干扰。
