    摘要： An apparatus is disclosed for range-based transmission parameter adjustment. In an example aspect, the apparatus includes a first antenna, a second antenna, and a wireless transceiver. The wireless transceiver is coupled to the first antenna and the second antenna. The wireless transceiver is configured to transmit a proximity detection signal via the first antenna. The wireless transceiver is also configured to receive a reflected proximity detection signal via the second antenna. The reflected proximity detection signal including a portion of the proximity detection signal that is reflected by an object. The wireless transceiver is additionally configured to adjust a transmission parameter based on the reflected proximity detection signal. The transmission parameter varies according to a range to the object. The wireless transceiver is further configured to transmit an uplink signal using the transmission parameter.

    摘要： A tunable multi-band receiver supporting operation on a plurality of frequency bands is disclosed. In an exemplary design, the tunable multi-band receiver includes an antenna tuning network, a tunable notch filter, and at least one low noise amplifier (LNA). The antenna tuning network tunes an antenna (e.g., a diversity antenna) to a receive band in a plurality of receive bands. The tunable notch filter is tunable to a transmit band in a plurality of transmit bands and attenuates signal components in the transmit band. One LNA among the at least one LNA amplifies an output signal from the tunable notch filter. The tunable multi-band receiver may further include one or more additional tunable notch filters to further attenuate the signal components in the transmit band.
