    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.

    摘要: Downlink control information, DCI, messages used for signaling downlink resource grants are employed for triggering sounding reference signal transmission in the uplink. An index of the uplink component carrier that should be used for the transmission is derived from SIB-2 linking between the downlink component carrier targeted by the downlink DCI message and one of the uplink component carriers configured for the mobile station, when the linking is available. In some cases the downlink component carrier targeted by the downlink DCI message is identified by a carrier identification field in the downlink DCI. Variants of the disclosed techniques involve a default uplink component carrier, which is used in the event that the SIB-2 based allocation is not possible or desired. The default uplink component carrier can be statically defined or semi-statically signaled by Radio Resource Control, RRC, signaling.

    摘要: A technique for generating a reference signal for use in a communication system in which for reference signal generation multiple base sequences are defined is presented. A method implementation of the technique comprises generating a first reference signal sequence from a first base sequence and a second reference signal sequence from a second base sequence. A reference signal is generated that comprises the first reference signal sequence and the second reference signal sequence. The first reference signal sequence occupies a first spectral fragment of the reference signal, and the second reference signal sequence occupies a second spectral fragment of the reference signal. The second spectral fragment and the first spectral fragment do not overlap.
