摘要： In a transmitter or transceiver, codewords from HARQ processes can be mapped or assigned to various layers for transmission and/or retransmission of information on a radio channel. Exemplary embodiments provide for various mappings which facilitate, for example, HARQ processes. For example, a codeword (700 or 720) can be mapped onto a plurality of layers (702, 704 or 722, 724, 726) which are equal in number to a channel rank of a radio channel to be used for the transmission.

摘要： Systems and methods for low complexity multi-configuration Channel State Information (CSI) reporting are provided. In some embodiments, a method of operating a wireless device in a cellular communications network to provide CSI feedback from multiple CSI reporting configurations is provided. The method includes receiving a first and second CSI reporting configuration and then reporting updated CSI in a CSI report for only one of the first CSI reporting configuration and the second CSI reporting configuration. In this way, rich CSI feedback with many ports, different codebooks, mixed beamformed and non- precoded CSI-RS configurations, etc., can be supported while requiring less computational complexity in the wireless device.

摘要： The present disclosure relates to methods and devices for mitigating inter-cluster interference in clusters where one or more network nodes are transmitting in coordination using several transceiver antennas. In particular the disclosure relates to improved precoder algorithms to be used for coordinated multipoint transmission applications. The disclosure also relates to corresponding computer programs. The disclosure proposes a method, performed in a coordination unit in a communication system, of mitigating inter-cluster interference, wherein the coordination unit is configured to coordinate transmissions in a cluster comprising one or more wireless devices and one or more network nodes, wherein the one or more network nodes are transmitting in coordination to the wireless devices in the cluster using several transceiver antennas. The method comprises receiving S2, for each transceiver antenna in each of the one or more network nodes 110a, a signal comprising pre-defined sounding sequences transmitted by the one or more wireless devices of the cluster and sounding channel interference from one or more wireless devices outside the cluster. The method further comprises estimating S4, from the received signal, the sounding channel interference from the wireless devices outside the cluster. The method also comprises determining S5 downlink precoder weights, for use when transmitting from the transceiver antennas of the cluster, using the estimated sounding channel interference from the one or more wireless devices outside the cluster.

摘要： A network node (10) signals to a wireless communication device (14) which precoders in a codebook are restricted from being used. The network node (10) in this regard generates codebook subset restriction signaling that, for each of one or more groups of precoders, jointly restricts the precoders in the group by restricting a certain component (e.g., a certain beam precoder) that the precoders in the group have in common. This signaling may be for instance rank-agnostic signaling that jointly restricts the precoders in a group without regard to the precoders' transmission rank. Regardless, the network node (10) sends the generated signaling to the wireless communication device (14).

摘要： Techniques disclosed herein provide for prohibiting use by a User Equipment (UE) (12) of configured Tracking Reference Signals (TRSs) (30). For example, under certain conditions or circumstances, the UE (12) is prohibited from using any configured TRS (30) for time or frequency tracking, for reception by the UE (12) of a physical downlink channel (32). For example, when TRS usage is prohibited for time or frequency tracking for reception of a physical downlink channel (32), the UE (12) uses Demodulation Reference Symbols (DMRS) transmitted for the physical downlink channel (32), for such time or frequency tracking.
