    • Techniques for conveying system bandwidths in a wireless communication system are described. In an aspect, system bandwidth information may be signaled to first user equipments (UEs) supporting a first set of system bandwidths and second UEs supporting a second set of system bandwidths. In one design, a base station may obtain and broadcast system bandwidth information indicating a first system bandwidth for the first UEs and a second system bandwidth for the second UEs. The first system bandwidth may be selected from the first set, and the second system bandwidth may be selected from the second set, which may be a superset of the first set. The system bandwidth information may include a first part and a second part. The first part may convey the first system bandwidth for the first UEs. The first and second parts may convey the second system bandwidth for the second UEs.

    • Techniques for performing frequency hopping in a wireless network are described. In an aspect, frequency hopping may be performed based on both cell identity (ID) and system time information. In one design, a user equipment (UE) may determine a cell ID of a cell and may obtain system time information for the cell. The UE may determine resources to use for transmission with frequency hopping based on the cell ID and the system time information. In one design, the UE may initialize a PN generator in each radio frame with an initial value determined based on the cell ID and a system frame number (SFN) for the radio frame. The UE may determine the resources to use for transmission based on a hopping function, a mirroring function, and a PN sequence from the PN generator. The UE may send a transmission on the resources to the cell.
    • 描述用于在无线网络中执行跳频的技术。 在一个方面,可以基于小区标识(ID)和系统时间信息来执行跳频。 在一种设计中,用户设备(UE)可以确定小区的小区ID,并且可以获得小区的系统时间信息。 UE可以基于小区ID和系统时间信息来确定用于使用跳频进行传输的资源。 在一种设计中,UE可以利用基于小区ID确定的初始值和无线电帧的系统帧号(SFN)来初始化每个无线电帧中的PN发生器。 基于来自PN发生器的跳频功能,镜像功能和PN序列,UE可以确定用于传输的资源。 UE可以向资源发送资源上的传输。

    • Aspects disclosed herein relate to channel and interference estimations in a multiple transmission point environment including an eNB and RRHs. In the disclosed aspects, one or more transmission points can signal to a UE to measure channel state conditions based on a first and a second resource pattern. The UE may receive the signaling and perform interference estimation based at least in part on the first resource pattern, and channel estimation based at least in part on the second resource pattern. The UE may generate a channel state report based on the interference and channel estimations, and transmit the channel state report to a transmission point. The eNB may employ the received channel state report in scheduling one or more resources for use by the UE, and may select or adjust network traffic on the first and the second resource pattern, to affect the resulting channel and interference estimation.
