摘要： 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.

摘要： 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.

摘要： 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.

摘要： A method, an apparatus, and a computer program product for wireless communication are provided for separating control transmissions and data transmissions within the coverage area of a plurality of transmission/reception points or points that are geographically displaced, the plurality of points comprising a macro node and a plurality of remote radio heads (RRHs) coupled to the macro node. Separating control transmissions and data transmissions in the macro node/RRH configuration may allow UEs to be associated with one set of transmission points for data transmissions and the same set or a different set of transmission points for common control signaling. Separating control transmissions and data transmissions may also allow for faster reconfiguration of antenna ports used for UE data transmission compared with reconfiguration via a handover process.

摘要： Wireless networks may include remote radio heads (RRHs) for extending the coverage of a macro cell. The macro cell may be connected to the RRHs, for example, by optical fiber, and there may be negligible latency between the macro cell and the RRHs. As a user equipment (UE) moves within the macro cell, or between other macro cells, mobility procedures followed by the UE may vary based on the release of the UE (e.g., Rel-8/9, Rel-10, or Rel-11 and beyond). The macro cell may handle all the scheduling within the cell, for itself and the RRHs.
