    摘要： In a heterogeneous cell deployment a mobile terminal may need to receive control data transmissions from a macro node at the same time as a pico node is transmitting user data for the mobile terminal, using the same frequency or set of frequencies. This can result in a problematic interference situation. According to several embodiments of the present invention, at least one of two general approaches is used to mitigate the interference situation described above. In a first approach, the pico node's transmission power is reduced in some time intervals, thereby reducing the interference to a level where reception from the macro node is possible. In a second approach, which may be combined with the first approach in some cases, the data transmitted from the macro node is provided by the pico node, either alone or in combination with the macro node.

    摘要： Particular embodiments provide a method in a network node (110) for requesting a channel state information-only, CSI-only, report from a wireless terminal (120). The method comprises selecting (210), based on at least one parameter related to transmission of the CSI-only report, a transport block out of two or more available transport blocks, such that the at least one parameter is derivable from an indication of which transport block was selected. The network node then transmits (220) an uplink grant to the wireless terminal (110). The uplink grant comprises the request for the CSI-only report, and also comprises an indication of the selected transport block.

The receiving unit includes: a network interface which obtains information relating to a time-varying layout of a silent resource element (RE) grid; an electronic memory having code in communication with the network interface which stores the information; and a processing unit in communication with the electronic memory that takes a presence of a silent RE grid into account in the reception of a control or a data channel.A method for a receiving/transmitting unit of a wireless network for facilitating noise and interference measurements on an air interface is described. Information relating to a time-varying layout of a silent resource element (RE) grid is obtained and a presence of a silent RE grid is taken into account in the reception of a control or a data channel.

    摘要： Systems and methods for generating a demodulation reference signal for use by user equipment configured with multiple antennas based on a rank of an antenna or an antenna port are disclosed. A rank for a user equipment device is determined indicating the number of spatial layers or antenna ports in use, and the value of the rank is used to generate a cyclic shift offset and a cyclic shift, that can then be used to generate a demodulation reference signal to be used in timeslots within each spatial layer of an uplink transmission. Orthogonal cover codes may be used in conjunction with a determined cyclic shift to generate a demodulation reference signal.
