Embodiment Construction

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

[0061] In some embodiments of the invention, reference is made 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 HARQ-ACK request to be transmitted, and determine the distance between adjacent HARQ-ACK modulation symbols. Relative distance among the reserved resources reserved for HARQ-ACK on PUSCH.

[0063] Here, according to the HARQ-ACK data information that actually needs to be transmitted and / or the reserved resource information reserved for HARQ-ACK on the PUSCH, determine the preset reserved for HARQ-ACK on the PUSCH between ad...

Abstract

The present invention provides a resource mapping method and device, which relate to the communication field, and solve the problem in the prior art that there is no specific method for determining RE resources occupied by actual HARQ-ACK information. The method includes: determining the relative distance between adjacent HARQ-ACK modulation symbols in the reserved resource according to the HARQ-ACK data information to be transmitted and / or the reserved resource information reserved for HARQ-ACK on the PUSCH; The relative distance determines the mapping result of the HARQ‑ACK modulation symbol to be transmitted in the reserved resource. The present invention provides a scheme for determining HARQ-ACK transmission resources on PUSCH, which is simple to implement, and can ensure that actual HARQ-ACK resources are completely mapped within reserved resources, and ensure that HARQ-ACK is as discretely distributed as possible on PUSCH , which improves transmission performance.

Description

technical field [0001] The present invention relates to the field of communications, and in particular, to a resource mapping method and device. Background technique [0002] Currently in an NR (New Radio, new air interface) communication system, HARQ-ACK (Hybrid Automatic RepeatreQuest ACKnowlegement, Hybrid Automatic Repeat Request Acknowledgement) can be transmitted through PUSCH (Physical Uplink Shared Channel, Physical Uplink Shared Channel). [0003] When the number of HARQ-ACK information bits is greater than 2, the HARQ-ACK and other information on the PUSCH are multiplexed and transmitted in a rate-matching manner. At present, clear HARQ-ACK mapping rules have been defined, for example: HARQ-ACK in the first After each DMRS (Demodulation Reference Signal, demodulation reference signal) symbols are mapped in the order of frequency domain first and then time domain; the current work assumes that if the RE (Resource Element, resource unit) resources occupied by HARQ-AC...
