Embodiment 1

[0108] In the LTE-A system, the base station schedules a physical uplink shared channel for single-antenna port transmission or multi-antenna port transmission through the downlink control information. The downlink control information is sent by the base station to the target user terminal through a physical downlink control channel.

[0109] The uplink scheduling information carried by the downlink control information includes but is not limited to:

[0110] Joint indication information of the cyclic shift and the orthogonal mask of the demodulation reference signal; wherein, the joint indication information of the cyclic shift and the orthogonal mask of the demodulation reference signal is 3 bits or 4 bits.

[0111] Orthogonal resources can be used (n DMRS (2) (0),n OCC ) to jointly represent the cyclic shift and the orthogonal mask sent by the base station to the target user terminal. in,

[0112] no DMRS (2) (0) represents the cyclic shift of the demodulation refere...

Abstract

The invention discloses a signaling configuration method and a signaling configuration system for a physical uplink shared channel. The system comprises a base station and a target user terminal. In the method, the base station sends downlink control information to the target user terminal through a physical uplink control channel; and the target user terminal receives the downlink control information in the physical uplink control channel to acquire orthogonal mask information and/or cyclic shift information, wherein the downlink control information carries the orthogonal mask information and/or the cyclic shift information for scheduling a physical uplink shared channel of multi-antenna port transmission and/or single antenna port transmission. In the downlink control information, a plurality of information combination modes can be adopted to indicate the orthogonal mask information, along with high applicability and flexibility; and meanwhile, the terminal can correctly acquire the orthogonal mask information so as to improve the service reliability.

Description

technical field [0001] The invention relates to the field of mobile communication, in particular to a signaling configuration method and system for a physical uplink shared channel. Background technique [0002] In the 3GPP LTE (The 3rd Generation Partnership Project Long Term Evolution, 3rd Generation Partnership Project Long Term Evolution) system, the centralized scheduling method of the base station is used to control the Physical Uplink Shared Channel (Physical Uplink Shared Channel) of the user terminal (User Equipment, UE). PUSCH) transmission. [0003] Uplink scheduling information (uplink scheduling information) on the physical uplink shared channel PUSCH is sent by the base station to the target UE through a physical downlink control channel (Physical Downlink Control Channel, PDCCH). The uplink scheduling information includes control information such as resource allocation related to the channel, a modulation and coding scheme, and a cyclic shift (Cyclic shift) o...
