Problems solved by technology

[0010] However, eMTC users are not allowed to perform frequency hopping between time domains. Therefore, the PUCCH resource reservation scheme for legacy users cannot be applied to eMTC users, and the PUCCH resource reservation algorithm needs to be redesigned

Embodiment Construction

[0062] In order to solve the problem that eMTC users use the existing PUCCH resource reservation method to have conflicts, in the embodiment of the present invention, for traditional users, at least one PRB located at the edge of both sides of the frequency band is reserved as format2 / 2a / 2b format The first resource for transmitting PUCCH, for eMTC users, reserve at least one PRB located inside the first resource as the second resource for transmitting PUCCH in format2 / 2a / 2b format, and at least one PRB located inside the second resource PRB, reserved as the third resource for transmitting PUCCH according to format1 / 1a / 1b format, for traditional users, at least one PRB located inside the third resource is reserved as the fourth resource for transmitting PUCCH according to format1 / 1a / 1b format .

[0063] Preferred embodiments of the present invention will be described in detail below in conjunction with the accompanying drawings.

Abstract

The invention relates to the field of digital communication, in particular to an eMTC PUCCH resource reservation method and device, which are used for redesigning PUCCH resource reservation for an eMTC user. The method comprises the following steps of: for a traditional user, reserving at least one PRB located at the most edge of the two sides of the frequency band as first resources; reserving atleast one PRB located on the inner sides of the first resources as second resources for an eMTC user, reserving at least one PRB located on the inner sides of the second resources as third resources,and reserving at least one PRB located on the inner sides of the third resources as fourth resources for a traditional user. Thus, resources in different frequency domains are reserved for the Legacyuser and the eMTC user respectively, PUCCH resources transmitted by the Legacy user and the eMTC user are reasonably isolated, and the situation that smooth scheduling cannot be achieved due to conflicts between the resources of different kinds of users is avoided.

Description

technical field [0001] The present invention relates to the field of digital communication, in particular to an eMTC PUCCH resource reservation method and device. Background technique [0002] In a Long Term Evolution (LTE) system, an uplink subframe can be divided into a control region and a data region in the frequency domain. The control region is provided for the Physical Uplink Control Channel (PUCCH), and the data The area is provided for use by an uplink shared channel (Physical Uplink Shared Channel, PUSCH). [0003] see figure 1 As shown, the control region is located at the edge of the frequency band, and the frequency domain widths of the upper and lower edges are usually symmetrical and equal, and the frequency domain width of each side is an integer multiple of 12 subcarriers. In the prior art, in the LTE system, one subframe occupies two time slots (slots), and in one subframe, PUCCH is transmitted on both sides of the frequency band by frequency hopping. Fo...
