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： A method for transmitting an acknowledgement/negative acknowledgement is described. Cell-specific symbol-level cyclic shift hopping is applied to data single-carrier frequency division multiplexing symbols of the acknowledgement/negative acknowledgement. A discrete Fourier transform is applied to the data single-carrier frequency division multiplexing symbols. Cell-specific symbol-level phase hopping is applied to the data single-carrier frequency division multiplexing symbols. The data single-carrier frequency division multiplexing symbols are transmitted in a slot.

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： A precoding scheme to accommodate user equipment (UEs) having higher Doppler speeds. In such transmission schemes, a different precoding matrix is applied to each orthogonal frequency division multiplex (OFDM) symbol in the transmission stream. Additionally, a downlink control message format is defined to handle assignment of multiple different transmission schemes using the same message format. The downlink control message format includes a control element in one of the message fields along with a set of parameters specifically applicable to the assigned transmission scheme. Based on the value of this control element, the UE sets the specific transmission scheme and determines a set of interpretation rules uniquely associated with that transmission scheme. Using the interpretation rules, the UE is able to read the set of parameters as applied to the selected transmission scheme.

摘要： Certain aspects of the present disclosure provide techniques for implicitly linking aperiodic channel state information (A-CSI) reports to CSI-reference signal (CSI-RS) resources. In an aspect, the UE may be instructed to report on specific CSI-RS resource(s) via explicit signaling in the UE grant. Other aspects disclose techniques for implicit CSI-RS resource selection by the UE that require fewer signaling resources. Instead of explicitly signaling CSI-RS resources to the UE, the UE may implicitly select CSI-RS resource for CSI feedback reporting based on information known to the UE, e.g. a subframe on which a reporting request is received. This may reduce the impact of the additional signaling in the UE grant.

摘要： Certain aspects of the present disclosure provide methods and apparatus for interleaving control information for one or more nodes.
