摘要： A method for operating an access node for transmission of radio signals in a plurality of beams of a beam sweep, includes: transmitting a first radio signal using a first polarization in a first beam having a first beam direction, and transmitting a second radio signal using a second polarization, which is different from the first polarization, in a second beam in said first beam direction, wherein the transmission of the first radio signal is linked to the transmission of the second radio signal in accordance with a predetermined rule. By means of such a link, a communication device may determine, based on the predetermined rule, that the first and second beams have a common directionality, but are configured for transmission with different, preferably orthogonal, polarization.

摘要： A wireless communication device includes a wireless interface for conducting wireless communications with a network access node of a wireless network, the wireless interface having uplink and downlink beam forming capabilities. The wireless communication device further includes a control circuit configured to detect a predetermined condition and, in response to the detection, temporarily operate the wireless interface without beam correspondence between uplink and downlink operations; and transmit a message to the network access node that beam correspondence is not used by the wireless communication device.

摘要： A method for performing a listen-before-talk procedure in a first transceiver device (N1) for wireless electromagnetic communication in a frequency band (150) is disclosed. A first transceiver device (N1) configured to perform the method is also disclosed. The method comprises receiving at the first transceiver device (N1) a stream of data (11) from a second transceiver device (N2), and determining whether the second transceiver device (N2) is capable of receiving in only a single or in two polarization directions. If the second transceiver device (N2) is capable of receiving in two polarization directions, then the method comprises determining and using an energy threshold that is larger than a regulated energy threshold for listen-before-talk within the frequency band (150). If the second transceiver device (N2) is capable of receiving in only a single polarization direction or if the energy of the received stream of data (11) is smaller than the energy threshold, then constructing a signal to be transmitted within the frequency band (150) by the first transceiver device (N1).

摘要： A method includes receiving (402) a plurality of reference signals (301-303) at an antenna port of a communication device (101). Each reference signal (301-303) is sent using a corresponding precoder. The precoder is selected from a first set of precoders. The method further includes determining (403) a channel estimate based on the received plurality of reference signals (301-303), and selecting (404) a precoder from a second set of precoders based on the determined channel estimate. The second set of precoders comprises at least one precoder in addition to the precoders of the first set of precoders. The method includes sending (405) an indication (304) relating to the selected precoder.

摘要： Methods (10, 30) and devices (20, 40) for performing radio transmissions in a wireless communication network are provided. A method (30) associated with a wireless terminal (40, 40A) which performs radio transmissions in the wireless communication network comprises: receiving (31) a multiple input multiple output, MIMO, transmission from an access node (20) of the wireless communication network; estimating (32) a spatial orientation (θ, (ϕ)) of an antenna array (42) of the wireless terminal (40, 40A) based on measurements performed by at least one sensor (43) of the wireless terminal (40, 40A); and based on the estimated spatial orientation (θ, (ϕ)), filtering out (33) a polarization crosstalk from the received MIMO transmission, the polarization crosstalk being associated with the spatial orientation (θ, (ϕ)) of the antenna array (42) of the wireless terminal (40, 40A).
