Embodiment Construction

[0060] In order to make the technical problems, technical solutions and advantages to be solved by the present invention clearer, the following will describe in detail with reference to the drawings and specific embodiments.

[0061] In some embodiments of the invention, referring to figure 1 As shown, a resource mapping method is provided, including:

[0062] Step 101: Confirm the HARQ-ACK data information and / or the reserved resource information reserved for HARQ-ACK on the physical uplink shared channel PUSCH according to the hybrid automatic repeat request that needs to be transmitted, and determine the distance between adjacent HARQ-ACK modulation symbols Relative distance in reserved resources reserved for HARQ-ACK on PUSCH.

[0063] Here, the reserved resources reserved for HARQ-ACK on PUSCH between adjacent HARQ-ACK modulation symbols are determined according to the HARQ-ACK data information that actually needs to be transmitted and / or the reserved resource informatio...

Abstract

The invention provides a resource mapping method and device, relates to the field of communication, and solves the problem of how to determine RE resources occupied by actual HARQ-ACK information in the prior art. The method comprises the following steps of: according to HARQ-ACK data information to be transmitted and / or reserved resource information for HARQ-ACK on PUSCH, determining relative distance between adjacent HARQ-ACK modulation symbols in reserved resources; determining a mapping result of the HARQ-ACK modulation symbols needing to be transmitted in the reserved resource according to the relative distance. The determination scheme of HARQ-ACK transmission resource on the PUSCH is given in the present invention. Implementation is simple, and it can be ensured that the actual HARQACK resources are completely mapped in the reserved resources and the HARQACK can be discretely distributed on the PUSCH as much as possible, so that the transmission performance is improved.

Description

technical field [0001] The present invention relates to the communication field, in particular to a resource mapping method and device. Background technique [0002] At present, in the NR (New Radio, new air interface) communication system, HARQ-ACK (Hybrid Automatic RepeatreQuest ACKnowlegement, hybrid automatic repeat request confirmation) can be transmitted through PUSCH (Physical UplinkShared Channel, physical uplink shared channel). [0003] When the number of information bits of HARQ-ACK is greater than 2, HARQ-ACK and other information on PUSCH are multiplexed and transmitted by rate matching. Currently, a clear HARQ-ACK mapping rule has been defined, for example: HARQ-ACK is first A DMRS (Demodulation Reference Signal, demodulation reference signal) symbol is then mapped in the order of the frequency domain and then the time domain; the current working assumption is that if the RE (Resource Element, resource unit) resource occupied by HARQ-ACK does not occupy a full ...
