METHOD AND DEVICE FOR DATA TRANSMISSION

摘要

Disclosed are a method and a device for data transmission, which relate to the field of wireless communication technologies, and are used for decreasing signaling overhead of a system in this application, an eNB delivers a scheduling radio network temporary identifier RNTI to a terminal; the eNB schedules uplink resources and/or downlink resources for the terminal through a physical downlink control channel PDCCH scrambled by using the scheduling RNTI, receives uplink data sent by the terminal on the scheduled uplink resources, and sends downlink data to the terminal on the scheduled downlink resources. The terminal monitors the PDCCH scrambled by using the scheduling RNTI, and sends the uplink data and/or receives the downlink data by using the resources scheduled by the monitored PDCCH. The method of this application can be used to effectively decrease the signaling overhead of the system.

1. A method for transmitting data, comprising:
an eNB sending a scheduling Radio Network Temporary Identifier, RNTI, for scheduling a resource to a user equipment; and the eNB creating a context for the user equipment, scheduling an uplink resource and/or a downlink resource for the user equipment over a Physical Downlink Control Channel, PDCCH, scrambled by the scheduling RNTI according to the context, receiving uplink data transmitted from the user equipment over the scheduled uplink resource and transmitting downlink data to the user equipment over the scheduled downlink resource.
