Embodiment 1

[0073] According to the method, the signaling type carried by the PUCCH is mapped in blocks (that is, in regions), and the PUCCH resources of all component carrier frequencies are continuously mapped in each block according to the component carrier frequencies.

[0074] Specifically,

[0075] Assume that a certain uplink component carrier frequency corresponds to two downlink component carrier frequencies (component carrier frequency 1 and component carrier frequency 2 respectively), and resources are divided into blocks according to PUCCH types in the PUCCH resource region.

[0076] Such as Figure 4 As shown, in each block of a PUCCH type, the PUCCH resources of this type of all component carriers are sequentially mapped and arranged according to the component carrier frequencies. The PUCCH resource of component carrier frequency 1 is first mapped sequentially, and then the PUCCH resource of component carrier frequency 2 is sequentially mapped.

[0077] Such as Figure 8 ...

Embodiment 2

[0079] In this method, block mapping is performed according to the PUCCH type. In each block, the PUCCH resources of all component carrier frequencies are interleaved and mapped in blocks according to the component carrier frequencies, or the PUCCH resources of each component carrier frequency in a block can be dynamically allocated through high-layer signaling.

[0080] Assume that at this time, a certain uplink component carrier frequency corresponds to two downlink component carrier frequencies (component carrier frequency 1 and component carrier frequency 2 respectively), and resources are divided into blocks according to PUCCH types in the PUCCH resource region.

[0081] Such as Figure 5 As shown, in each PUCCH-type block, each component carrier maps and arranges the PUCCH indexes of all component carriers in blocks and interleaves (first maps the first part of PUCCH resources of component carrier 1 in order of interleaving size, and then maps The first part of PUCCH re...

Embodiment 3

[0084] The method maps in blocks according to the PUCCH type, and continuously maps the PUCCH resources of all component carrier frequencies in each block according to the component carrier frequencies.

[0085] Specifically,

[0086] by Image 6 For example, at this time, an uplink component carrier corresponds to three downlink component carriers (component carrier 1, component carrier 2, and component carrier 3), and resources are divided into blocks according to the PUCCH type in the PUCCH resource area . In each PUCCH type block, map and arrange all the PUCCH resources of this type of component carrier frequency in sequence according to the component carrier frequency (first map the PUCCH resource of component carrier frequency 1, then map the PUCCH resource of component carrier frequency 2, and finally map PUCCH resource of component carrier frequency 3). In each PUCCH type block, all resource indexes are arranged in descending order.

Abstract

The invention provides a physical uplink control signal path resource mapping method in large bandwidth system, comprising the steps as follows: an uplink component carrier frequency is divided into a plurality of regions; the physical uplink control signal path carrying the same type of signaling of a plurality of downlink component carrier frequencies corresponding to the uplink component carrier frequency is mapped to the different resources in the same region of the uplink component carrier frequency. The invention also provides a physical uplink control signal path resource mapping device. The invention resolves the problem of the physical uplink control signal path resource mapping.

Description

technical field [0001] The invention relates to the field of mobile wireless communication, in particular to a method and device for mapping uplink control channel resources in a large bandwidth wireless communication system. Background technique [0002] figure 1 The frame structure of the FDD (Frequency Division Duplex, frequency division duplex) mode and the TDD (Time Division Duplex, time division duplex) mode of the LTE (Long Term Evolution, long term evolution) system is shown. In the frame structure of FDD mode, a 10ms radio frame (wireless frame) consists of twenty slots (time slots) with a length of 0.5ms and numbers 0 to 19, and time slots 2i and 2i+1 form a subframe with a length of 1ms (subframe)i. In the frame structure of the TDD mode, a 10ms radio frame (wireless frame) consists of two half frames (half frames) with a length of 5ms, and a half frame contains five subframes (subframes) with a length of 1ms. Subframe i is defined as two time slots 2i and 2i+1...
