Abstract
A radio frequency (RF) unit and method of operation of the RF unit are disclosed herein. The RF unit comprises an antenna array, and the antenna array comprises a plurality of antenna elements. A first set of the plurality of antenna elements is configured to operate in a first mode and a second set of the plurality of antenna elements is configured to operate in a second mode. In the first mode, the first set of the plurality of antenna elements is configured to transmit and receive. In the second mode, the second set of the plurality of antenna elements is configured to only receive.
Claims18
A radio frequency (RF) unit comprising:
- an antenna array comprising a plurality of antenna elements, wherein:
- a first set of the plurality of antenna elements is configured to operate in a Time Division Duplex (TDD) mode in a frequency band,
- a second set of the plurality of antenna elements is configured to operate in an enhanced duplexing mode in the frequency band,
- in the TDD mode, the first set of the plurality of antenna elements is configured to transmit and receive in the frequency band, and
- in the enhanced duplexing mode:
- the first set of the plurality of antenna elements is configured to transmit and not receive in the frequency band;
- and
- the second set of the plurality of antenna elements is configured to receive in the frequency band in a same time slot in which the first set of the plurality of antenna elements is configured to transmit in the frequency band.
A method of operation of a radio frequency (RF) unit, comprising:
- transmitting and receiving, in a Time Division Duplex (TDD) mode, first transmit and first receive signals in a frequency band via a first set of a plurality of antenna elements of an antenna array of the RF unit;
- and
- in an enhanced duplexing mode:
- transmitting second transmit signals in the frequency band via the first set of the plurality of antenna elements, and
- receiving second receive signals in the frequency band via a second set of the plurality of antenna elements of the antenna array of the RF unit in a same time slot in which the first set of the plurality of antenna elements transmits the second transmit signals in the frequency band.
