  • Publication number: 20180351630
    Abstract: A UE RX beam training procedure in which a user equipment (UE) is configured with “interference” information indicating one or more reference signals (RSs) that the UE should consider as interference. For example, it is proposed here to include such interference information in a transmitted beam training configuration for a UE RX beam training procedure to be performed by the UE.

  • Publication number: 20180351629
    Abstract: A UE RX beam training procedure in which a user equipment (UE) is configured such that the UE selects a UE RX beam based not only on a measurement of a first reference signal (RS1) transmitted using a first TX beam, but also based on a measurement of a second reference signal (RS2) transmitted using a second TX beam. For example, the UE may be provisioned with “interference” information indicating one or more reference signals that the UE should consider as interference. An advantage with these proposals is that the UE RX beam can be determined not only on maximizing received power, but also by taking predicted interference in to account, which can lead to a higher quality of service and/or a higher throughput.

  • Publication number: 20180348328
    Abstract: There is provided mechanisms for estimating angle of arrival of a radio signal in a radio communications network. A method is performed by a receiving radio transceiver device. The method comprises obtaining measurements of the radio signal as received in two receive beams covering a given angular sector. The two receive beams are created by analog beamforming in an antenna array. The receive beams have different complex beam patterns and at any angle within the given angular sector at most one of the complex beam patterns has gain below a threshold. The method comprises estimating the angle of arrival of the radio signal by comparing a complex amplitude of the measurements in the two receive beams to a discriminator function.

  • Publication number: 20180343044
    Abstract: There is provided mechanisms for obtaining channel conditions per antenna element of an antenna array comprising N antenna elements. The antenna array is configured for communications using orthogonal sub-carriers. A method is performed by a radio transceiver device. The method comprises obtaining channel conditions of a radio propagation channel per sub-carrier for signals received on the sub-carriers by the antenna array. A set of receiving entities are associated with the sub-carriers in an interleaved manner such that each receiving entity is interleaved over a respective disjoint subset of sub-carriers. The method comprises transforming the channel conditions at least for those sub-carriers located within a coherence bandwidth of the radio propagation channel to channel conditions for the N antenna elements by using a relation that maps the receiving entities to the N antenna elements.

  • Publication number: 20180338289
    Abstract: An energy efficient UE 100 comprising a plurality of antenna ports 110 is provided by enabling selective deactivation of at least some transmission chain(s) associated with the antenna port(s) 110 that are not transmitting signals, e.g., SRSs and/or other wireless signals. The UE 100 determines how quickly/how much each channel associated with each antenna port 110 changes, and identifies a subset of antenna ports having a rate of change estimate that satisfies a rate of change requirement as being part of a deactivation subset of antenna ports 110. The UE 100 not only ceases transmitting signals from the antenna ports 110 in the deactivation subset, but also deactivates each of the transmission chains 122 operatively connected to the antenna ports 110 in the deactivation subset. In so doing, the UE 100 eliminates unnecessary power consumption without unduly impacting performance.

  • Publication number: 20180323839
    Abstract: There is provided mechanisms for obtaining channel conditions per antenna element, A method is performed by a wireless radio transceiver device comprising N antenna elements in an antenna array with analog beamforming and being configured to communicate using beams. The method comprises obtaining, for a stationary radio propagation channel, channel conditions for signals received by the wireless radio transceiver device in M beams, where M>1. The method comprises transforming the channel conditions for the M beams to channel conditions for the N antenna elements by using a relation based on beamforming weights that map the N antenna elements to the M beams.

  • Publication number: 20180316402
    Abstract: There is provided mechanisms for configuring an antenna system having individual antenna elements arranged in at least two antenna subarrays. Each pair of antenna subarrays has a respective first spatial separation. Each pair of the individual antenna elements has a respective second spatial separation. A method is performed by a network device. The method includes obtaining channel measurements for each of the at least two antenna subarrays. Channel covariance information between the subarrays using the obtained channel measurements is determined. Channel covariance information between all individual antenna elements of the antenna system is determined by interpolating the channel covariance information between the subarrays according to a spatial relation between all first spatial separations and all second spatial separations. Combining of the individual antenna elements of the antenna system is controlled based on the determined channel covariance information between all the individual antenna elements.

  • Publication number: 20180302863
    Abstract: A wireless device (12) is configured to transmit a signal simultaneously from a group (104) of physical antenna ports (106), based on associating disjoint frequency sub-bands with respective ones of the physical antenna ports (106). The frequency sub-bands collectively span a frequency bandwidth and each physical antenna port (106) supports transmission over the frequency bandwidth and has a per-port transmit power associated therewith. The wireless device (12) is configured to transmit the signal further based on allocating the per-port transmit power of each physical antenna port (106) in the group (104) only to frequency elements of the signal that fall within the frequency sub-band associated with the physical antenna port (106). A radio network node (10) in a network (16) is configured to perform channel estimation based on receiving a reference signal from the wireless device (12) and its channel estimation accounts for channel changes that may appear at the border between two frequency sub-bands.
