Problems solved by technology

However, this method also has the following disadvantages: since the number of sub-blocks is fixed, the size of each sub-block is the same, and the sub-blocks are staggered, this will cause the mapping relationship between the PUCCH index and the CCE index of the PDCCH to be unsuitable for LTE- LTE Rel-8 terminals in the Advanced system, that is to say, this method is not compatible with LTE Rel-8 terminals

Embodiment Construction

[0044] Before describing the technical solution of the present invention in detail, the basic principle of the method for dynamic PUCCH resource reservation and index mapping of the present invention is firstly introduced.

[0045] First of all, the dynamic PUCCH resources required by each downlink component carrier still adopt the resource reservation method of block interleaving on the uplink component carrier, specifically: first divide the dynamic PUCCH resources required by each downlink component carrier into multiple sub-blocks, and each The size of the dynamic PUCCH resources corresponding to the sub-blocks is semi-statically configured by the upper layer; then these sub-blocks are arranged according to the downlink component carrier index interleaving mapping.

[0046] Further, the number of sub-blocks of each downlink component carrier can also be statically configured by the high layer, that is, the number of sub-blocks can be fixed; it can also be semi-statically co...

Abstract

The invention discloses a method for reserving and index-mapping dynamic physical uplink control channel (PUCCH) resources, which comprises the steps of: dividing the dynamic PUCCH resources required by each downlink component carrier into a plurality of sub-blocks; collocating the size of the dynamic PUCCH resource corresponding to a first sub-block of each downlink component carrier to be greater than or equal to the size of the dynamic PUCCH resource required by an LTE (Long Term Evolution) Rel-8 terminal so as to locate the dynamic PUCCH resource required by the LTE Rel-8 terminal in the first sub-block of the downlink component carrier; mapping and arranging each sub-block in a cross mode according to the index of the downlink component carrier; and calculating the index of the dynamic PUCCH resource corresponding to an i+1th downlink component carrier according to a first control channel unit index of a physical downlink control channel corresponding to the i+1th downlink component carrier on the basis of the allocation. The invention also discloses a device for reserving and index-mapping the dynamic PUCCH resources.

Description

technical field [0001] The present invention relates to resource reservation technology in Long Term Evolution (LTE, Long Term Evolution), in particular to a method and device for dynamic Physical Uplink Control Channel (PUCCH, Physical Uplink Control Channel) resource reservation and index mapping under large bandwidth. Background technique [0002] At present, an advanced International Mobile Telecommunications (IMT-Advanced, International Mobile Telecommunications-Advanced) system can realize high-speed data transmission and has a large system capacity. In the case of low-speed mobile and hotspot coverage, the peak rate of the IMT-Advanced system can reach 1Gbit / s; in the case of high-speed mobile and wide-area coverage, the peak rate of the IMT-Advanced system can reach 100Mbit / s. [0003] In order to meet the requirements of the advanced International Telecommunication Union (ITU-Advanced, International Telecommunication Union-Advanced), the advanced long-term evolution...
