Abstract: Systems and methods related to Hybrid Automatic Repeat Request (HARQ) timing for Downlink Control Information (DCI) scheduling multiple cells are disclosed. In one embodiment, a method performed by a wireless communication device comprises receiving, from a base station, a DCI that schedules downlink transmissions to the wireless communication 5 device on two or more serving cells. The method further comprises receiving and decoding the downlink transmissions on the two or more serving cells scheduled by the DCI. The method further comprises determining a slot in which to transmit HARQ feedback for the downlink transmissions on the two or more serving cells scheduled by the DCI based on a single HARQ feedback timing indicator comprised in the DCI and a reference timing and transmitting, to the 0 base station, HARQ feedback for the downlink transmissions on the two or more serving cells scheduled by the DCI in the determined slot.

Abstract: There is provided a method for controlling interference in a received signal when scheduling in a network node for wireless communication with a set of user equipment's, UEs, said set comprising a first UE and at least a second UE, wherein the interference is passive-intermodulation interference, PIM. The method comprises receiving a scheduling request from at least the first UE transmitting on a first frequency and scheduling at least the first UE based on an interference scenario report and available PIM cancellation resources to enable efficient PIM control. The method is performed by a control device.

Abstract: A method of operating a network node in a wireless communication system includes configuring a downlink control information (DCI) message that schedules uplink or downlink communications with a user equipment (UE) in a plurality of serving cells. The DCI message does not include an explicit new data indicator (NDI) field for at least one of the serving cells scheduled by the DCI message. The network node transmits the DCI message to the UE. A method performed by a UE includes receiving a DCI message that schedules uplink or downlink communications in a plurality of serving cells. The DCI message does not include an explicit NDI field for a serving cell scheduled by the DCI message. In response, the UE determines an NDI value associated with scheduled communications for the serving cell or determines that the scheduled communications for the serving cell contains a new data transmission.

Abstract: The present invention relates to the field of communication technology with regard to cell scheduling. A method of operating a network node comprises transmitting a single Downlink Control Information (DCI) to a radio node, the single DCI scheduling Physical Downlink Shared Channels (PDSCHs) on a plurality of cells. The single DCI indicates a counter downlink assignment indicator (DAI) which is either based on the plurality of scheduled cells or independent of the plurality of cells scheduled by the single DCI.

The network node includes processing circuitry configured to indicate, in downlink control information, DCI, a first modulation and coding scheme, MCS, associated with first transport block, TB, indicate, in the DCI, a second MCS associated with a second TB where the first MCS is indicated by a first MCS field size and the second MCS is indicated by a second MCS field size less than the first MCS field size, and communicate with the wireless device based on the first MCS and the second MCS.

Abstract: A technique for transmitting and receiving scheduling information to a radio device from a network node of a radio access network, RAN, is described. The network node is in radio communication with the radio device through at least two cells. As to a method aspect of the technique, a configuration information is received from the network node. The configuration information is indicative of at least one table comprising at least two alternatives of the scheduling information for each of the at least two cells. Furthermore, control information is received from the network node. The control information is indicative of a reference to one of the at least two alternatives of the scheduling information for each of the at least two cells.

Abstract: Disclosed is a method performed by a network device (1) for controlling the scheduling of signal transmissions and/or signal receptions for a first communication device (10) operating according to a first Radio Access Technology, first RAT, and a second communication device (20) operating according to a second Radio Access Technology, second RAT, said communication devices (10; 20) sharing a common frequency carrier and operating using an Orthogonal Frequency Division Multiplexing modulation scheme, OFDM modulation scheme. The method comprises the step of coordinating (S1) the scheduling of said first communication device (10) and said second communication device (20) within a common Time Transmission Interval, TTI, such that the first communication device (10) is scheduled on a first subset of the Orthogonal Frequency Division Multiplexing symbols, OFDM symbols, within said TTI and said second communication device (20) is scheduled on a second subset of said OFDM symbols within said TTI.

Abstract: The present disclosure relates to over-the-air, OTA, reciprocity calibration for a distributed multiple input-multiple output, D-MIMO, system. By having antennas of the system divided in two separate groups, based on pairwise path loss, and by performing two measurements only, one of which is transmitting by the first group and simultaneously receiving by the second group, and the second by transmitting by the second group and simultaneously receiving by the first group, relations between receiver and transmitter impairments used in the measurements are determined, assuming reciprocity. By relating receive to transmitter impairments for each antenna relative to one or more anchor antennas, calibration values are calculated. By adjusting a quota of the receiver to the transmitter impairment for each antenna such that the relations are fulfilled, reciprocity calibration is achieved, based on two measurements only.
