Method, base station and user equipment for transmitting dispatching information

Abstract

The invention discloses a method, base station and user equipment for transmitting dispatching information. The method comprises the following steps of: determining at least the group of at least one user equipment; transmitting a wireless resource control message including the grouping information of the group to the at least one user equipment; respectively encapsulating the dispatching information of each dispatched user equipment in the at least one dispatched user equipment in the group in the CE (control element) of a MAC (media access control) control unit in a media access control MAC protocol data unit (PDU); and transmitting a control signaling to the at least one dispatched user equipment through a control channel, wherein the control signaling is used for dispatching the MAC PDU. The base station comprises a first determination module, a first transmitting module, an encapsulation module and a second transmission module. The user equipment comprises a first receiving module, a second receiving module and a decoding module. According to the method, base station and user equipment of the embodiment of the invention, the dispatching information can be transmitted in a combined dispatching module, the expense for controlling the channel can be saved, and the resource utilization can be improved.

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.
