摘要： Certain aspects of the present disclosure relate to techniques for determining resource elements REs used for Coordinated Multipoint (CoMP) transmission schemes. The techniques generally include determining, by a User Equipment (UE), a set of data REs used for Coordinated Multipoint (CoMP) operation. The determination is based on a CoMP scheme and data REs available to particular base stations involved in the CoMP operation. The technique further includes processing data received via the CoMP operation on the determined set of data REs.

摘要： Downlink rate adaptation in wireless communication systems are disclosed in which a UE reports RIs for both interference-free and interference-limited subframes. In general, the RI for the interference-free subframes will be higher than the RI reported for the interference-limited subframes. However, an eNB selects an RI and a transmission rate for interference-limited subframes based on what the UE can sustain instead of based only on the RI reported by the UE.

摘要： Certain aspects of the present disclosure provide techniques and apparatuses for wireless communications. According to certain aspects, a set of protected resources, allocated to a base station of a first cell, that are protected by restricting transmissions of a second cell is determined and received power of a first reference signal from the base station in the set of resources is measured. According to certain aspects, a subset of one or more neighbor base stations that have reduced interference in a set of protected resources is determined and received power measurements for the subset of neighbor cells is excluded when calculating receive signal quality measurements for the subframe.

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： Techniques for acknowledging data transmissions in a multi-carrier wireless communication network are disclosed. In one aspect, a UE determines a number of acknowledgement/negative acknowledgement (ACK/NACK) bits for a data transmission on one more component carriers (CCs) based on information obtained from a grant. The grant may be a downlink grant or an uplink grant, and the information obtained may include a number of CCs scheduled for data transmission and/or identifiers of the scheduled CCs. The UE may determine the number of ACK/NACK bits for acknowledging the data transmission based on the number of scheduled CCs and the identifier of each scheduled CC.
