Method, base station and user equipment for transmitting dispatching information

Abstract

The present invention discloses a method, base station, and user equipment for transmitting scheduling information. The method includes: determining a group to which at least one user equipment belongs; sending a radio resource control message to the at least one user equipment, where the radio resource control message includes group information of the group; encapsulating scheduling information of each scheduled user equipment in at least one scheduled user equipment in the group, into a MAC control element CE in a media access control MAC protocol data unit PDU; and sending control signaling to the at least one scheduled user equipment through a control channel, where the control signaling is used to schedule the MAC PDU. The base station includes a first determining module, a first sending module, an encapsulating module, and a second sending module. The user equipment includes a first receiving module, a second receiving module, and a decoding module. By using the method, base station, and user equipment of the embodiments of the present invention, scheduling information is transmitted in a group-based scheduling mode, thereby saving control channel overheads and improving utilization of resources.

Description

technical field [0001] The present invention relates to the communication field, in particular to a method for transmitting scheduling information in the communication field, a base station and user equipment. Background technique [0002] In a Long Term Evolution (referred to as "LTE") system, an evolved base station (evolved NodeB, referred to as "eNB") uses a Physical Downlink Control Channel (Physical Downlink Control Channel, referred to as "PDCCH") transmission for scheduling Control signaling of user equipment (User Equipment, "UE" for short). The control signaling includes physical channel resources allocated to the UE and specific modulation and coding scheme (Modulation and Codec Scheme, “MCS” for short) information and the like. After receiving the control signaling transmitted through the PDCCH, the UE analyzes the relevant information carried in the signaling, and sends and receives data on the corresponding physical channel according to the instructions therei...

AI Technical Summary

Problems solved by technology

The small data packets of these services have the characteristics of small data volume, large number of packets, and long packet intervals, so it is impossible to accumulate multiple small packets for simultaneous transmission

Therefore, when a large number of uplink small packets are transmitted, the use efficiency of PDCCH will be greatly reduced, the overhead of PDCCH will be increased, and the capacity of the system will be limited due to the limitation of PDCCH.
