In a portable telephone according to the present invention, a display displays a block indicative of an operator, predetermined information and a pointer; the operator can be operated in directions opposite to each other; and the controller controls the display so as to shift the pointer to a desirable position within a predetermined information on a screen of the display in accordance with an operation of the operator and also display a mark indicative of a direction to which the pointer can be shifted and in which the predetermined information exists, adjacently to the block along a shift direction through the operator.

A network device includes: a radio configured to operate in a 2.4 GHz Wi-Fi band; a 32 bit double data rate (DDR) memory having instructions stored therein; a system clock configured to operate at 533 MHz; and a processor. The processor is configured to execute the instructions stored on the memory to cause the network device to: operate the 32 bit DDR memory at 1067 MHz; instruct the radio to transmit data to be transmitted in the 2.4 GHz Wi-Fi band; and instruct the radio to receive data to be received in the 2.4 GHz Wi-Fi band.

A method of separating a desired signal from an undesired signal includes obtaining a total input signal comprising the desired signal and the undesired signal in a time domain occupying a time duration from time t.sub.1 to time t.sub.2 of a single symbol in the desired signal. A transform is performed of the total input signal wherein an output of the transform is a time domain signal representing the desired signal.

A multiple input, multiple output (“MIMO”) antenna system is provided for operation on a radio frequency (“RF”) module that may be used in a wireless access device. The MIMO antenna system includes a plurality of multi-band antenna elements connected to a radio in a MIMO configuration. The multi-band antenna elements and the radio are configured to operate on an RF module. A reflector is formed on the RF module to contain the plurality of multi-band antenna elements and a common director is positioned in front of the multi-band antenna elements to concentrate signal communication in a sector. The plurality of multi-band antenna elements are oriented to provide a sector coverage pattern formed by beam patterns generated by each of the multi-band antenna elements.

A method for performing self-interference cancellation by a terminal may comprise the steps of: receiving RS configuration information for phase estimation of self-interference from a base station; when the terminal operates, with a distributed antenna structure, in a full duplex radio (FDR) mode or operates in a space division duplex (SDD) mode between panels, transmitting an RS on the basis of the RS configuration information; and performing phase estimation for self-interference between the panels on the basis of the RS. The terminal is capable of communicating with at least one of another terminal, a terminal related to an autonomous driving vehicle, a base station or a network.

Methods and apparatus to mitigate radio frequency interference generated by hardware circuitry and received by wireless circuitry of a wireless communication device are described. A processor obtains a set of wireless performance metrics for signals received by the wireless circuitry. The processor determines a preferred operating mode for the hardware circuitry based on the set of wireless performance metrics and provides an indication of the preferred operating mode to the hardware circuitry. The hardware circuitry is configured for operation in accordance with the preferred operating mode. The processor and/or a second processor provide an indication to the wireless circuitry when the hardware circuitry initiates and terminates an operation that can cause radio frequency interference into the wireless circuitry. The wireless circuitry is configured during a time period that the hardware circuitry is operational to mitigate effects of radio frequency interference generated by the hardware circuitry.
