    摘要: An aspect of this invention is a definition of a set of reused channel state information reference signal (CSI-RS) resources among transmission points, which can be lower power nodes, for intra-cell coordinated multi-point (CoMP) operation. Separate CSI-RS resources are defined for each transmission point for sporadic separate measurements to be made by user equipment. The sporadic measurements may be implemented with low additional overhead, and are used for generating potentially simplified CSI feedback to an evolved NodeB that enables adapting shared channel reuse and also potentially making related channel quality indicator (CQI) compensation.

    摘要: An apparatus includes one or more processor and one or more memories including computer program code. The one or more memories and the computer program code are configured to, with the one or more processors and in response to execution of the computer program code, cause the apparatus to perform at least the following: accessing in an enhanced downlink control region of a downlink subframe a downlink control channel message corresponding to the apparatus, wherein the downlink control channel message corresponding to the apparatus occupies two or more physical resource blocks contiguous in one or both of time and frequency; and accessing or not accessing a portion specific to the apparatus of a physical downlink shared channel in the downlink subframe, depending in least in part on the determined downlink control channel message. Additional apparatus, methods, and computer products are disclosed.

    摘要: The exemplary embodiments of the invention relate to at least a method and apparatus to perform determining, at a user device, an initial signal power of a cell specific reference signal and a signal power for each reference signal of at least one reference signal in a network; identifying a change as compared to at least one of the initial signal power of the cell specific reference signal and the at least one reference signal; and based on the identifying, triggering another determining of a signal power of reference signals of the at least one reference signal in the network. Further, the exemplary embodiments relate to at least a method and apparatus to perform configuring, at a network device, at least one reference signal, sending, towards a user equipment of a network, information including an indication of the at least one reference signal, sending, towards the user equipment a request to perform signal power or signal quality measurements of the indicated at least one reference signal; and sending, towards the user equipment of a network, a threshold to be used by the user equipment of the network in the measurement procedure of signal power or signal quality of the indicated at least on reference signal.

    摘要: A network signals an allocation (PDCCH) for a downlink shared channel (PDSCH); and also signals an indication (reference signal RS) whether a resource block (PRB) comprising the allocated downlink shared channel is used for a control channel transmission (E-PDCCH). Examples include the E-PDCCH being time or frequency multiplexed with the PDSCH; and the indication being a different RS sequence (at least one element being phase shifted) than an original RS sequence used if the PRB were not used for the E-PDCCH. The UE tests for the phase shift by blind decoding. If the phase shift is present the UE a) decodes a portion of the PRB for data if the network is using TDM for its E-PDCCH/PDSCH multiplexing, or b) decodes the full PRB only for the E-PDCCH if the network is using FDM for its E-PDCCH/PDSCH multiplexing.

    摘要: A first parameter such as an indicator of modulation and coding scheme MCS for a first shared channel SCH codeword and a second parameter for a second SCH codeword are determined. From a locally stored mapping rule a bit sequence that explicitly indicates the first parameter and that implicitly indicates the second parameter is chosen, and a first control channel CCH codeword is transmitted with the explicit bit sequence that explicitly indicates the first parameter for the first SCH codeword and a second CCH codeword is sent companion to the first CCH codeword, wherein the second parameter for the second SCH codeword is implicitly indicated by the explicit bit sequence of the first CCH codeword. The receiving party determines the second parameter by its own locally stored mapping rule, and an indicator in each CCH codeword may be used to inform the receiver that the two (or more) CCH codewords are associated with one another and to use its mapping rule to determine the second parameter.

    摘要: Pilot sequences (for aiding a receiver in estimating a channel) are disposed in a frame structure that has subframes of sub-carriers and symbol positions. Locations of common pilot sequences are predetermined, and includes 1) in each subframe, a pilot sequence is disposed in a first symbol position for each of at least two staggered sub-carriers, and 2) in at least one subframe, at least one pilot sequence is disposed in other than the first symbol position and in a sub-carrier other than any of the at least two staggered sub-carriers. Dedicated pilot sequences, whose locations in the frame are not predetermined, are disposed in response to an indication of channel quality received over a wireless link. Common pilot sequences may relate to one or two transmit antennas, and dedicated pilot sequences may enable addition of third and fourth transmit antennas.

    摘要: A method is disclosed that includes selecting one or more terminals involved in a device-to- device communication to which interference caused by a transmission to one or more other terminals should be suppressed, and choosing a number of degrees of freedom from a predetermined number of degrees of freedom to be used to suppress interference towards the selected one or more terminals. The method also includes using the remaining degrees of freedom from the predetermined number to increase signal quality to the one or more other terminals and performing precoding based on the chosen number of degrees of freedom and the remaining degrees of freedom. The method further includes, using at least the performed precoding, transmitting information to the one or more other terminals. Apparatus and programs/program products are also disclosed.
