摘要： A wireless transmission system included at least one user equipment and a base station. The base station is operable to form a downlink control information block, modulate the downlink control information, precode the modulated downlink control information, and transmit the precoded, modulated downlink control information on at least one demodulation reference signal antenna port to the at least one user equipment. The precoded, modulated downlink control information is mapped to a set of N1 physical resource block pairs in a subframe from an orthogonal frequency division multiplexing symbol T1 to and orthogonal frequency division multiplexing symbol T2.

摘要： This patent application considers the configuration aperiodic sounding reference signal parameters by radio resource control signaling and the triggering of aperiodic SRS transmission by detection of a positive trigger in downlink control information. Transmission timing rules are also proposed to determine the valid subframes for aperiodic SRS transmission.

摘要： A base station selects a subset of at least one geographically separated antennas for each of the plurality of user equipments. The base station forms at least layer of data stream including modulated symbols, precodes the data stream via multiplication with the NT-by-N precoding matrix where N is the number of said layers and NT is the number of transmit antenna elements and transmits the precoded layers of data stream to the user equipment via the selected geographically separated antennas. The base station signals the subset of the plurality of geographically separated antennas via higher layer Radio Resource Control or via a down link grant mechanism. The base station optionally does not signal the subset of the plurality of geographically separated antennas to the corresponding mobile user equipment.

摘要： This invention includes signaling schemes for communicating the PDSCH muting configuration from the eNodeB to its UEs so that they can measure inter-cell CSI if configured. The base station transmits to each served user equipment a number signal indicating a number of allowed muting configurations, parameters for each allowed muting configuration and an enable/disable signal. Each served user equipment mutes or does not mute a physical downlink shared channel according to one of the allowed muting configurations and the state of a corresponding bit of the enable/disable signal.
