Abstract: An antenna switching method includes tuning respective signals provided to first and second antennas in a portable electronic device to at least one frequency band. The method may also include connecting the first antenna to an uplink signal path that is for transmissions through the first and second antennas, and performing impedance matching for the first antenna. The method may further include comparing a real-time performance characteristic of the first antenna with a real-time performance characteristic of the second antenna. The method may additionally include, responsive to determining that the second antenna has a stronger real-time performance characteristic than the first antenna while the first antenna is connected to the uplink signal path, switching from the first antenna to the second antenna by connecting the second antenna to the uplink signal path and disconnecting the first antenna from the uplink signal path, and performing impedance matching for the second antenna.

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: 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.

Abstract: Methods (50, 60) are provided for operating first and second network nodes (80, 90) of a wireless network which participate (51, 61) in a multiple input multiple output, MIMO, wireless transmission. The network nodes (80, 90) respectively comprise an antenna array (20, 30, 91) having antenna elements (11, 12) being associated with respective ones of two mutually orthogonal planes of polarization. The respective method (50, 60) comprises: communicating (54, 64), by the first network node (80) and to the second network node (90), a sequence of pilot symbols, each of which is associated with one of a set of mutually distinct states of polarization for transmission of the respective pilot symbol; and communicating (55, 65), by the second network node (90) and to the first network node (80), at least one feedback signal associated with the pilot symbols. The at least one feedback signal is indicative of a set state of polarization. The method (50) for operating the first network node (80) further comprises: configuring (56) the antenna array (20, 30) according to the set state of polarization

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 desired mode for communication between an electronic device (14) and a network node (12). Determining the desired mode for communication is based on the electronic device's (14) capabilities and/or the channel conditions of the communication channel between the electronic device (14) and the network node (12). The procedures described herein may allow for the high data rates associated with polarization based MIMO (P-MIMO) in capably equipped electronic devices (14) while preventing communication interruptions due to unfavorable channel conditions.

Wherein the first uplink reference signal transmission is associated with a receive beam having a first opening angle. Wherein the second uplink reference signal transmission is associated with a receive beam having a second opening angle. The first opening angle is smaller than the second opening angle.
