A communication device for communication in one or more mobile communication systems has a selection device for coupling one or more mobile radio antennas to one or more signal paths on the basis of a selection signal. The communication device also has a transceiver module, which is designed to generate the selection signal and to communicate in the one or more mobile communication systems by way of the coupled mobile radio antennas. The transceiver module is designed to select, on the basis of two or more user identifications, different mobile radio antennas for communication in the one or more mobile communication systems by way of the selection signal. The transceiver module is designed to take isolation and/or correlation between the mobile radio antennas into account in the selection.

An apparatus may operate in a dual connectivity mode in which the apparatus is simultaneously connected to carriers of different radio access technologies. The apparatus may operate via a first antenna set of a plurality of antenna sets, the first antenna set including a first communication path. The apparatus may determine to operate via a second antenna set of the plurality of antenna sets based on whether one or more criteria is satisfied. The apparatus may select at least one second communication path for the second antenna set based on the one or more criteria. The apparatus may operate via the second antenna set over the at least one second communication path when the criteria is satisfied.

A wireless communication device may receive with one of N antennas a signal processing message indicating a number up to N signals to process. Each of the N antennas may used to receive a communication. The indicated number of up to N signals may be processed and data from the indicated number of up to N signals recovered.

A receiver circuit for an antenna array system (AAS) is disclosed. The receiver circuit (10) comprises a set of receivers (15.sub.1-15.sub.p). Each receiver (15.sub.1-15.sub.p) comprises a first TI-ADC (35.sub.1) in a receive path of the receiver. The first TI-ADC (35.sub.1) comprises a plurality of sub ADCs (A.sub.1-A.sub.M+N). Each receiver (15.sub.1-15.sub.p) comprises a control circuit (40) configured to select which sub ADC (A.sub.1-A.sub.M+N) is to operate on what input sample based on a first selection sequence. The control circuits (40) in the different receivers (15.sub.1-15.sub.p) in said set of receivers (15.sub.1-15.sub.p) are configured to use different first selection sequences.

A network node in a wireless communication network generates configuration information that configures an extent to which a wireless communication device autonomously adapts a number of different receiver components that the wireless communication device uses under different conditions at the wireless communication device. In some examples, the different conditions may be associated with correlation of propagation channels received at the wireless communication device. The network node transmits the configuration information to the device. Correspondingly, the device autonomously adapts the number of different receiver components that the wireless communication device uses in accordance with the configuration information.

Disclosed is technology for improving the quality of an IoT service by avoiding using a frequency band in which signal disturbance occurs and using a BS in an overload state.

An electronic device including a plurality of antenna modules configured to wireless communicate with a base station according to a first communication scheme; a plurality of temperature sensors respectively provided in the plurality of antenna modules and configured to detect a temperature of each antenna module; and a modem configured to detect a temperature difference between a highest temperature antenna module and a lowest temperature antenna module among the plurality of antenna modules, and switch from using a first antenna module performing wireless communication with the base station to a second antenna module among the plurality of antenna modules to perform the wireless communication with the base station based on the detected temperature difference being above a preset temperature difference.

Receive diversity combining uses signals received at multiple antennas and combine them to obtain a higher overall signal to noise ratio. Multi-level ranking is employed to determine the weight assigned to each channel and, once the channels are weighted the weighted signals are added together. In a two-level example the first level ranks the signals according to fidelity of the signal. This is done by calculating cross correlation coefficients, where highest coefficient indicates best fidelity. The second level ranks the channels according to peak to average power ratio. The lowest value indicates the best channel. The two rankings are combined to generate the weight coefficient for each channel prior to combining the signals from all the channels.

Methods, systems, and devices for wireless communications are described. In some systems, a first device and a second device may communicate over a communication link using a set of antenna elements. The first device may identify one or more antenna array reconfiguration trigger conditions and may correspondingly select a first subset of antenna elements for operation. The first device may transmit a message to the second device including an indication of the antenna array reconfiguration at the first device, a request for the second device to modify the second device's antenna array configuration, or both. The second device may receive the message and, based on the indication or the request, may modify its antenna array configuration. For example, the second device may select a second subset of antenna elements based on the selected first subset of antenna elements. The devices may communicate using their modified antenna array configurations.
