Problems solved by technology

[0004] In order to overcome the problems existing in the related technologies, embodiments of the present disclosure provide a physical layer resource mapping method, device, user equipment, and base station, which are used to modulate HARQ-ACK when HARQ-ACK modulation symbols and uplink data are multiplexed and transmitted The symbols are evenly distributed to as many OFDM symbols as possible in the frequency domain, avoiding the uplink caused by the concentrated distribution of HARQ-ACK modulation symbols on one or several OFDM symbols. The problem of slow performance of data transfer

Abstract

The present disclosure relates to a physical layer resource mapping method, device, user equipment and base station. The method includes: when HARQ-ACK information and uplink data are multiplexed and transmitted, determine the starting position and frequency domain offset value of HARQ-ACK modulation symbols mapped to physical layer resources, and the frequency domain offset values ​​are different HARQ-ACK The frequency domain offset of the resource element to which the -ACK modulation symbol is mapped; based on the starting position and the frequency domain offset value, each HARQ-ACK modulation symbol is mapped to a corresponding resource element. The technical solution of the present disclosure can realize that each HARQ-ACK modulation symbol is evenly distributed to as many OFDM symbols as possible in the frequency domain, and avoids the centralized distribution of the HARQ-ACK modulation symbols on one or several The problem of performance degradation of uplink data transmission caused by OFDM symbols.

Description

Technical field [0001] The present disclosure relates to the field of communication technology, and in particular to a physical layer resource mapping method, device, user equipment, and base station. Background technique [0002] In the Long Term Evolution (LTE) system, when the uplink data transmission of the user equipment and the uplink control information transmission overlap in the time domain, the uplink control information to be transmitted can be used as the uplink to be transmitted. As part of the data, the time domain and frequency domain resources of uplink data transmission are multiplexed to realize the transmission of uplink control information. In LTE, when the uplink Hybrid Automatic RepeatreQuest Acknowledgement (Hybrid Automatic RepeatreQuest Acknowledgement, referred to as HARQ ACK) information and uplink data are multiplexed for transmission, the HARQ-ACK modulation symbol is mapped to two adjacent demodulation reference signals (Demodulation Reference Signal...
