Abstract: A method (20) performed by a wireless terminal (10) in a wireless communication network (10, 30) is provided. In the method (20), based on a (fundamental) polarization tracking capability of the wireless terminal (10), at least one downlink polarization of at least one downlink communication between the wireless terminal (10) and an access node (30) of the wireless communication network (10, 30) is determined (204). A reference polarization from the at least one downlink polarization is selected (207). Based on the reference polarization and a (momentary) polarization tracking ability of the wireless terminal (10), at least one uplink polarization of at least one uplink communication between the wireless terminal (10) and the access node (30) is configured (210). A corresponding method (40) performed by the access node (30) is also provided, as well as the mentioned wireless terminal (10) and the access node (30).

Abstract: 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.

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).

Abstract: A method of operating a device (101, 102) includes selecting between a first operational mode (8098) and a second operational mode (8099) for a wireless link (111) established between a terminal (102) and a base station (101) of the network; in response to selecting the first operational mode (8098): determining first values for antenna weights from a plurality of predefined candidate values; and in response to selecting the second operational mode (8099): determining second values for the antenna weights based on a calculation using a receive property of pilot signals (4021) communicated between the terminal (102) and the base station (101) as an input.

Abstract: A half-duplex radio device (100) generates a repetitive transmission of an uplink message to a base station (150) of the cellular network. The radio device (100) splits the repetitive transmission of the uplink message into a sequence of multiple transmit periods and configures at least one measurement gap between the transmit periods. In the transmit periods, the radio device (100) sends the repetitive transmission to the base station. In the at least one measurement gap configured between the transmit periods, the radio device (100) temporarily switches to receiving at least one downlink signal from the base station (150). Based on the received at least one downlink signal, the radio device (100) estimates a frequency error of a reference frequency source of the radio device (100).

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 of configuring a multichannel uplink transmission (199) comprising multiple channels (151, 152, 159, 451, 452) between a wireless communication device (102) and multiple receive panels (1013-1, 1013-2) of at least one network node (101) is provided. The multiple receive panels (1013-1, 1013-2) and the at least one network node (101) are connected via backhaul links (1018-1, 1018-2). The method is carried out by the wireless communication device (102). The method comprises receiving, from the at least one network node (101), a downlink message encoding control data (4001) for the multichannel uplink transmission (199), the control data (4001) being associated with the backhaul links. The method further comprises configuring the multichannel uplink transmission (199) based on the control data (4001).

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.
