DOWNLINK INFORMATION SENDING METHOD AND RECEIVING METHOD, BASE STATION, AND USER DEVICE
First Claim
1. A downlink information sending method, comprising:
- allocating a cell radio network temporary identifier (C-RNTI) and an extension identifier to a first user device, wherein a combination of the extension identifier and the C-RNTI is used to identify the first user device;
notifying the first user device of the C-RNTI and the extension identifier;
scrambling downlink control information (DCI) of the first user device by using the C-RNTI; and
sending the scrambled DCI, wherein the scrambled DCI carries the C-RNTI and the extension identifier for communicating with a network according to the DCI when determining that the notified C-RNTI and the C-RNTI in the scrambled DCI are the same and the notified extension identifier and the extension identifier carried in the DCI are the same, orsending a Media Access Control control element (MAC CE) and the scrambled DCI, wherein the MAC CE carries the extension identifier, so that the first user device communicates with a network according to the DCI when determining that the notified C-RNTI and the C-RNTI in the scrambled DCI are the same and the notified extension identifier and the extension identifier carried in the MAC CE are the same.
