Embodiment Construction

[0031] Since PUCCH format 3 supports multi-user multiplexed transmission in a time-domain spread spectrum manner, the selected length of the orthogonal spread spectrum sequence will directly affect the number of multiplexed users on a PRB pair. In the embodiment of the present invention, a configuration and determination scheme of PUCCH format 3 resources will be given, which can effectively solve the problem of inconsistent multiplexing capacity of PUCCH format 3 resources in SRS subframes and non-SRS subframes. Specific embodiments of the present invention will be described below in conjunction with the accompanying drawings.

[0032] In order to facilitate the understanding of how to implement the present invention, in the description process, the implementation of the UE and the base station will be described separately, and then the coordinated implementation of the two will be described in the embodiment, but this does not mean that the two must be Coordinated implementa...

Abstract

The invention discloses a resource allocation and determination method and equipment both for an uplink control channel, which comprise steps that a base station allocates physical uplink control channel resources which are used by user equipment in a physical uplink control channel format (3) to perform acknowledgement character / negative acknowledge (ACK) / (NAK) feedback, and the base station inform the user equipment of physical uplink control channel resources which are used by the user equipment through explicit signaling. The user equipment ensures the physical uplink control channel resources which are used for performing the ACK / NAK feedback in the physical uplink control channel form (3) according the explicit signaling. When the user equipment transmits in the physical uplink control channel form (3), the method and the equipment can enable resources which are capable of supporting to transmit exploration reference signals and ACK / NAK in the same subframe and resources which are not capable of supporting to transmit exploration reference signals and ACK / NAK in the same subframe to be identical in multiplexing volume.

Description

technical field [0001] The present invention relates to wireless communication technology, in particular to a method and device for configuring and determining uplink control channel resources. Background technique [0002] In 3GPP Rel-10 (Release 10) LTE-A (Long Term Evolution-Advanced, long-term evolution upgrade), UE (User Equipment, user equipment) can use PUCCH format 3 (PUCCH format 3; PUCCH: Physical Uplink Control Channel, Physical uplink control channel) (that is, DFT-S-OFDM, Discrete Fourier Transform-Spread-Orthogonal Frequency Division Multiplexing, discrete Fourier transform extended orthogonal frequency division multiplexing) feedback multi-bit ACK / NACK (Acknowledgment / Negative Acknowledgment, acknowledgment / negative acknowledgment). The PUCCH format 3 adopts a time-domain CDM (Code Division Multiplexing, code division multiplexing) manner, and supports multiple UEs on one PRB (physical resource block, physical resource block). Using the QPSK (Quaternary Ph...
