Problems solved by technology

Based on the above analysis, it can be seen that when transmitting downlink data to a certain group of user terminals through the existing technology, there is a problem of low utilization of network resources. Therefore, there is currently no group-based downlink data transmission method suitable for transmitting data to a certain group of user terminals

Embodiment Construction

[0055] In order to reduce the waste of network resources in M2M communication and improve the utilization rate of network resources, the embodiment of the present invention provides a downlink data transmission method, which forms a group of user terminals belonging to the same user or densely distributed in an area. Each group is uniquely identified by a Group ID, and the user terminal still monitors the first message in an idle state. The first message may be a paging message or a control channel message, wherein the control channel may be a PDCCH or a It is HS-SCCH. In addition to using its own UE_ID to monitor its own paging message according to the formulas 1 and 2 introduced in the background technology, the user terminal also needs to use its own identity (such as the Group ID of the group it belongs to), and according to the formula 2 introduced in the background technology Formula 1 and Formula 2 are used to monitor the first message sent for the belonging group of th...

Abstract

The invention relates to the technical field of communication and discloses a method and device for downlink data transmission. The method and device are used for reducing network resource waste when one group of user terminals in the side direction of a network transmits data and improving the utilization rate of network resources. The method includes the steps that specific user terminals are grouped, and each group is identified with a unique Group ID. Under the idle state, the user terminals monitor self paging information and first information. When transmitting the downlink data, a network side sends dispatch information of the downlink data transmission and pages the group of user terminals at the timing position of the group through the first information carrying the Group ID. The user terminals receiving the first information receive the downlink data at a time window and a fixed physical resource based on the dispatch information of the downlink data transmission. The effects that the network resource waste when the group of user terminals in the side direction of the network in M2M communication transmits the data is reduced, and the utilization rate of the networking resources is improved are achieved.

Description

technical field [0001] The present invention relates to the technical field of communications, in particular to a downlink data transmission method and device. Background technique [0002] In recent years, with the continuous development of communication technology, in addition to the more convenient communication and exchange between traditional H2H (Human to Human, people to people), the connection and dialogue between M2M (Machine to Machine, machine to machine) It has also gradually become the mainstream of communication development. [0003] M2M communication refers to the communication between machines. Unlike traditional H2H communication, M2M can automatically complete data collection, processing and transmission without manual intervention. An important feature of M2M communication is that there are many user terminals. The number of MTC (Machine Type Communication, Machine Type Communication) terminals is far greater than that of H2H user terminals, usually dozen...
