Abstract: 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.

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: Systems and methods for selecting a communication mode in a wireless network (10) include a communication mode selection procedure that may be carried out by the respective devices in an automated manner to identify a mode for communication between an electronic device (14) and a network node (12). The selection may be between P-MIMO Mode A, P-MIMO Mode B, B-MIMO Mode A, or B-MIMO Mode B. Determining the desired mode for communication is based on the ability and/or desirability of the network node (12) to efficiently process a maximum threshold number of electronic devices using the P-Mimo Mode A or B-MIMO Mode A and, thereafter, granting MIMO Mode B communication access to any subsequent electronic devices joining the communication network. Communication mode selection may occur dynamically based on changing channel conditions caused by mobility of the electronic user equipment devices and what overlapping and/or non-overlapping beams are needed to be used.
