DATA TRANSMISSION METHOD AND DEVICE

摘要

The present invention relates to the communications field, and discloses a data transmission method and device, so as to resolve a problem of low efficiency and excessively much power consumption when user equipment performs blind detection on a scheduling control channel. A specific solution is: receiving, by a first device, scheduling control channel length information, performing, by the first device, blind detection in a preset search space according to the scheduling control channel length information, and after detecting a scheduling control channel corresponding to the scheduling control channel length information, obtaining, by the first device, resource allocation information carried on the scheduling control channel. The present invention is applied to data transmission.

主权项

1. A data transmission device, comprising:
a receiver, configured to receive scheduling control channel length information, wherein the scheduling control channel length information comprises a quantity of physical resource units occupied by a scheduling control channel, and the scheduling control channel is a control channel used when resource allocation information is sent to the data transmission device; and a processor, configured to:
perform blind detection in a preset search space according to the scheduling control channel length information received by the receiver; andafter detecting the scheduling control channel corresponding to the scheduling control channel length information, obtain the resource allocation information carried on the scheduling control channel, wherein the preset search space is a search space used to carry the resource allocation information.
