Embodiment Construction

[0049] In order to improve the transmission performance of uplink control information, an embodiment of the present invention provides a method for scheduling and reporting uplink control information. In this method, the base station determines that it needs to use the semi-persistent scheduling (SPS) method to schedule the terminal through the Physical Uplink Shared Channel (PUSCH ) after periodically reporting the uplink control information, the scheduling terminal periodically reports the uplink control information through the PUSCH, and the terminal periodically reports the uplink control information through the PUSCH according to the scheduling of the base station.

[0050] see figure 2 The method for scheduling uplink control information provided by the embodiment of the present invention specifically includes the following steps:

[0051] Step 20: The base station determines the uplink SPS parameter value used by the terminal to periodically report uplink control infor...

Abstract

The embodiment of the invention discloses a scheduling and reporting method, system and device of uplink control information, relates to the technical field of wireless communication and aims to increase the transmission performance of uplink control information. In the method in the invention, a base station schedules terminals to report uplink control information periodically through a physicaluplink shared channel (PUSCH) and the terminals report uplink control information periodically through the PUSCH according to the scheduling of the base station. When the coverage of the physical uplink control channel (PUCCH) is not comprehensive enough and the reliability of the periodic uplink control information which is originally transmitted in the PUCCH can not be ensured, the transmissionperformance of the uplink control information can be greatly increased by reporting uplink control information periodically through the PUSCH.

Description

technical field [0001] The present invention relates to the field of wireless communication, in particular to a scheduling and reporting method, system and equipment for uplink control information. Background technique [0002] In the Long Term Evolution (LTE) system, the uplink control channel (PUCCH) is used to transmit synchronized uplink control information (UCI). The uplink control information transmitted on the PUCCH mainly includes uplink scheduling request (SR), downlink hybrid automatic repeat request confirmation ( HARQ-ACK) information, and periodic channel quality indicator (CQI) information of the terminal (UE). Among them, according to the allocation of PUCCH resources, the downlink HARQ-ACK information can be further divided into three parts: semi-persistent scheduling HARQ-ACK information, dynamic scheduling HARQ-ACK information, and acknowledgment / negative acknowledgment repetition (ACK / NACK repetition) information . UCI information and its corresponding r...
