摘要： Certain aspects of the present disclosure relate to techniques that may be used to discover transmission points in heterogeneous networks (HetNet) that involves coordinated multi-point (CoMP) transmission and reception. Certain aspects of the present disclosure provide a method for wireless communications by a user equipment (UE). The method generally includes receiving a configuration indicating distinct resources used by each of a plurality of different transmission points involved in coordinated multipoint (CoMP) operations with the UE for transmitting discovery reference signals (RSs), receiving distinct discovery RSs transmitted from the plurality of different transmission points, and calculating at least one of path loss or reference signal received power (RSRP) estimations for each of the transmission points based on the distinct discovery RSs.

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： 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.

摘要： A method of wireless communication includes determining a number of symbols for uplink control information (UCI) on each of a plurality of layers, multiplexing symbols for the UCI with data on multiple layers such that the symbols are time aligned across the layers, and sending the multiplexed symbols on the multiple layers on uplink. In some designs, the number of symbols for the UCI may be determined based on a spectral resource parameter.
