Problems solved by technology

[0003] The asymmetric supplementary uplink frequency band can improve the uplink throughput of the user equipment. However, the existing 3GPP terminals can support the transmission of downlink carrier aggregation, and there is no terminal equipment that can support the transmission of the asymmetric supplementary uplink frequency band.

Abstract

The invention provides a radio frequency unit and terminal equipment. The radio frequency unit includes: a main antenna, M transmit paths, N first receive paths, and a radio frequency chip; wherein, the M transmit paths are connected between the main antenna and the radio frequency chip, and the M transmit paths The channel is used to transmit the uplink signals of T frequency bands sent by the radio frequency chip to the main antenna; the main antenna is used to transmit the uplink signals and receive downlink signals of N frequency bands; the T frequency bands and the The N frequency bands are different, T≥M, M and T are positive integers; the N first receiving paths are connected between the main antenna and the radio frequency chip, and the N first receiving paths are used to The downlink signals of the N frequency bands are transmitted to the radio frequency chip, wherein, N

Description

technical field [0001] The present invention relates to communication technology, in particular to a radio frequency unit and terminal equipment. Background technique [0002] In an existing Long Term Evolution (LTE for short) system, a single carrier supports a maximum system bandwidth of 20M. If a larger bandwidth is required, a carrier aggregation technology needs to be used. In the 3rd Generation Partnership Project (3rd Generation Partnership Project, 3GPP for short), aggregation of a maximum of 5 carriers is supported, and the number of downlink carriers is required to be greater than or equal to the number of uplink carriers. In the public network operator's network, the downlink service requirements are generally greater than the uplink service requirements, and the downlink carrier aggregation defined by 3GPP can better meet the operator's network. However, different from the requirements of common public networks, in wireless communication networks of some industr...
