Abstract: A monitoring device or arrangement performs a method (30) of sensing physiological stress in a user based on sensor data from one or more sensors associated with the user. The method comprises: obtaining (31) stress parameter values (SPVs) that represent a physiological stress level in the user and that are generated at a measurement rate based on the sensor data; monitoring (33) the stress parameter values (SPVs) for detection of a switching point, which is detected when the stress parameter values indicate an elevated stress level in the user for a predefined time period; and causing (34) a reduction of the measurement rate upon detection of the switching point.

Abstract: A radio device applies a carrier frequency for transmission of data between the radio device and a base station of a cellular network. Further, the radio device configures a measurement time interval in which the radio device temporarily switches from the transmission of data to receiving at least one broadcast signal conveying system information from the base station. Based on the received at least one broadcast signal, the radio device estimates an offset of the carrier frequency as applied by the radio device to a frequency of a carrier signal as received from the base station.

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: 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.
