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 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: Methods (10; 30) and devices (20; 40) for controlling polarization division multiplex in a wireless communication network are provided. A method (10) associated with an access node of the wireless communication network comprises: the access node (20) controlling (11A) a first multiple input multiple output, MIMO, transmission between the access node (20) and a first wireless terminal (40, 40A) to use a first set of time-frequency resources, to use a first MEMO spatial channel, and to use a first receive polarization state of the first wireless terminal (40, 40A); and controlling (11B) a second MIMO transmission between the access node (20) and a second wireless terminal (40, 40B) to use a second set of time-frequency resources which at least partially overlaps the first set of time-frequency resources, to use a second MIMO spatial channel which at least partially overlaps the first MIMO spatial channel, and to use a second receive polarization state of the second wireless terminal (40, 40B) which differs from the first receive polarization state.

Abstract: Systems and methods for managing interference in a communication network include transmitting a first downlink signal (50) from a first transmit/receive point (TRP) (46) to an electronic device (14) using a beam (62). The electronic device (14) can also receive a second downlink signal (52) from a second TRP (48), where a portion (54) of the first downlink signal (50) from the first TRP (46) interferes with the second downlink signal (52). The first TRP (46) then receives a series of uplink pilot signals (66, 68) from the electronic device (14). Using the received uplink pilot signals (66, 68), the first TRP (46) can then estimate the angle of departure (AoD) for the intended signal (first downlink signal (50)), and the AoD for the interference signal (54). The first TRP (46) can then reconfigure the beam (62) used to transmit the first downlink signal (50) based on the estimated AoDs for the intended signal and interference signal to manage the interference effect that the first leakage signal (54) has on the second downlink signal (52).

Abstract: An antenna frame for a wireless communication device includes an end portion having a thickness that varies along the width of the end portion, with the goal of reducing the radar cross section of the end portion to improve end-fire transmission of vertically polarized antenna elements. Embodiments of an antenna frame may include an end portion with a plurality of notches in the top edge and/or the bottom edge. These notches may be at least partially filled with a dielectric material to improve end-fire transmission of horizontally polarized antenna elements.
