Abstract: A method provides information to a UE specifying a UL-DL configuration to be applied to the UE. The information is indicative of: (a) a signaling time at which a UL-DL configuration signaling for a new UL-DL configuration is to take place, and (b) an application time at which the new UL-DL configuration is to be applied. This method complements UL-DL configuration signaling by providing more reliable reception of UL-DL configuration information. This indication is performed with smaller signaling overhead compared to conventional schemes and with reasonable complexity on both the UE side and an eNB side.

Abstract: A downlink data transmission is performed in a downlink subframe. One or more resources are determined. The one or more resources are to be used for transmission or reception of error information for the received transmission in an uplink subframe based at least on an association set between one or more downlink or special subframes and an uplink subframe. The determined association set depends on a downlink reference configuration. The association set for each uplink subframe comprises a grouping of the downlink or special subframes into at least two groups. An association set is defined only for the subframes which are uplink subframes in a corresponding downlink reference configuration. The error information is transmitted or received using the determined one or more resources in the uplink subframe. Methods, apparatus, programs, and program products are disclosed.

Abstract: For an integer number R (greater than one) of demodulation reference signal DM RS resources that are reserved for SU-MIMO transmissions by a UE, there is associated in a memory a) for a first transmission instance each of the R DM RS resources with a unique one of R spatial layers or R transmit antennas, and b) for a second transmission instance each of the R DM RS resources with a different unique one of the R spatial layers or transmit antennas. The first and second transmission instances (slots or sub-frames) are consecutive. A UE transmission to a network in the first slot/sub-frame comprises each DM RS resource on the respective spatial layer or transmit antenna with which they are associated for the first slot/sub-frame, and a UE transmission to the network in the first slot/sub-frame comprises each DM RS resource on the respective spatial layer or transmit antenna with which they are associated for the second slot/sub-frame.

Abstract: A method includes applying a precoder to information to be transmitted on N antenna ports, wherein application of the precoder creates an M-Tx codebook, each codeword of which is obtained through truncation of a codeword from an N-Tx codebook corresponding to the N antenna ports. The precoded information is transmitted on the N antenna ports to a UE and information allowing an N-Tx codeword to be selected from the N-Tx codebook is received. The N-Tx codeword is truncated to an M-Tx codeword and the M-Tx codeword is used for a transmission to the UE. Another method includes receiving at a UE a transmission in first and second sets of N antenna ports, wherein the second set of antenna ports creates at least in part an M-Tx codebook. The UE searches the N-Tx codebook to determine an N-Tx codeword to be fed back and feeds back the N-Tx codeword.
