Abstract: 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.

Abstract: A method for operating an access node (20) for transmission of radio signals in a plurality of beams (50-55) of abeam sweep (310), comprising: —transmitting (605) a first radio signal (301) using a first polarization in a first beam (54) having a first beam direction, and —transmitting (605, 607) a second radio signal (302) using a second polarization, which is different from the first polarization, in a second beam (55) 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 (30) may determine, based on the predetermined rule, that the first (54) and second (55) beams have a common directionality, but are configured for transmission with different, preferably orthogonal, polarization.

Abstract: The present invention relates to a method for operating a base station (11) in a wireless radio network (10). The base station (11) comprises a plurality of antennas (12) for transmitting radio frequency signals between the base station (11) and a user equipment (UE1, UE2, UE3). According to the method, a transmission slot (47) is provided for receiving at each antenna (12) of a subset of the plurality of antennas (12) a training signal sent from the user equipment (UE1, UE2, UE3). For each antenna (12) a corresponding configuration parameter is determined based on the training signal received at the corresponding antenna (12) and payload information blocks (36, 37) to be transmitted between the base station (11) and the user equipment (UE1, UE2, UE3) are transmitted using the determined configuration parameters for the antennas (12). A deterioration parameter indicating a deterioration of a transmission between the base station (11) and the user equipment (UE1, UE2, UE3) due to a change in the transmission requiring adaption of the configuration parameters is determined. Based on the deterioration parameter, a timing parameter is determined for controlling when a further transmission slot (47) is to be provided for receiving at each antenna (12) a next training signal sent form the user equipment (UE1, UE2, UE3).

Abstract: 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).
