摘要： In one aspect, a RAN node determines UE candidate sets for MUST scheduling where each set includes near UE and far UE MUST positions. The node orders the UE candidate sets according to a scheduling performance metric for each UE candidate set, evaluated with respect to the entire band. The node resolves MUST pairing conflicts by excluding, from the UE candidate sets, any UE candidate set that includes a UE that (a) is also present in a UE candidate set having a better scheduling performance metric and (b) has an inconsistent MUST position for interference cancellation with respect to the better UE candidate set, to obtain a reduced set of UE candidate sets. The node performs subband scheduling on each subband, using either MUST or OMA transmission scheduling for each subband. The reduced set is used for MUST scheduling. MUST/OMA subband conflicts may also be resolved.

摘要： A reciprocity-based precoding algorithm is provided that accommodates for the specific type of uncertainty arising from the delay in channel estimation as a function of the velocity of moving wireless communication devices (103a-c). Account is taken of time delay from previous sounding times as well as the velocity of the wireless communication devices (103a-c) thereby providing an effective precoding scheme for beamforming.

摘要： Systems and methods are disclosed herein that relate to the use of signals in a licensed spectrum to assist with determining a status of an unlicensed channel(s) in an unlicensed spectrum. In some embodiments, a method of operation of a wireless device in a wireless system in which the wireless device transmits and/or receives in both a licensed spectrum and an unlicensed spectrum comprises attempting to detect a busy indication transmitted in the licensed spectrum. The busy indication is an indication that another wireless device is transmitting in the unlicensed spectrum. The method further comprises determining whether to transmit in the unlicensed spectrum based on whether the wireless device has detected a busy indication transmitted in the licensed spectrum. By using signals in the licensed spectrum, the hidden node problem and/or the exposed node problem in the unlicensed spectrum can be mitigated.

摘要： In an aspect, a wireless device with a plurality of transmitter chains that can be selectively used to transmit a beam-formed signal determines a targeted receive power for the beam-formed signal, with respect to a target receiving device. The wireless device selects a number of the plurality of transmitter chains for forming the beam- formed signal, based on the targeted receive power and based on an estimated power consumption for each of the plurality of transmitter chains. The selection is performed so as to minimize a total power consumption, given the estimated power consumptions. The wireless device transmits a beam-formed signal, using the selected number of the plurality of transmitter chains.

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.
