摘要： In a half-duplex communication system in which additional delays in the communication channel (18, 20) may cause a message collision between a message and a response, a collision detector (40a, 40b) is utilized to prevent and detect message collisions. The collision detector determines (204) if a response may be transmitted from the communication device while it is receiving the current message. If no response is expected, the collision detector is placed (214) into a train mode. If a response is possible, the collision detector is placed (206) into the monitor mode. In the monitor mode, the collision detector monitors the communication channel and determines (210) if a message collision has occurred during transmission of the message. A detection of a message collision causes retransmission of the message or possibly a new message at a later time after it has been determined (202) that the communication channel is clear.

摘要： A communication device includes a service transmitter (Tx) configured to transmit a second beam of RF signals in a first radiation pattern to a user equipment (UE). The communication device further includes a control circuitry configured to: detect an amount and direction of echo signals at the donor receiver Rx corresponding to reflected RF signals in an environment surrounding a communication device; determine an installation location for the communication device based on echo signal measurements at one or more different locations; adjust polarization of the second beam of RF signals to minimize the echo signals at the donor receiver Rx based on the echo signal; and generate a second radiation pattern for at least the second beam of RF signals based on the amount and direction of the echo signals in the environment detected at the donor receiver Rx.

摘要： A method and device for eliminating co-frequency and adjacent frequency interference in an analog domain, in the case that a wireless communication device with a receiving antenna, that is, a transmitting point of a master device, detects and judges the presence of co-frequency and/or adjacent frequency interference signal sources on site, collects the reference signals of the same frequency and/or adjacent frequency from the interference signal sources by means of cable direct connection or adding an antenna, and obtains the analog signals of the same frequency and/or adjacent frequency interference after interference signal recovery processing, then, in the analog domain, the received signal received by the receiving antenna of the master device is directly subtracted from the interference analog signal of the same frequency and/or adjacent frequency to complete the analog interference cancellation process, so as to obtain the interference canceled RF analog signal.

摘要： Methods and devices are described for compensating an effect of aging due to, for example, hot carrier injection, or other device degradation mechanisms affecting a current flow, in an RF amplifier. In one case a replica circuit is used to sense the aging of the RF amplifier and adjust a biasing of the RF amplifier accordingly.
