Description
Technical Field
The present application relates to the field of communications, and in particular, to a method and an apparatus for transmitting downlink control information.
Background
5G has become the latest generation technology of mobile communication, and various extended applications based on 5G will be developed rapidly. An important application of 5G is the use of unlicensed frequency bands. For unlicensed bands, coexistence usage of various wireless systems needs to be considered relative to licensed bands. Typical applications in unlicensed frequency bands are Wifi, LTE-based LAA technology, etc. In order to enable the harmonious coexistence of multiple technologies, regulatory bodies of various countries use a forced Listen Before Talk (LBT) technique for the use of unlicensed frequency bands, i.e., data transmission is enabled only when it is sensed that the current channel is not occupied. A problem with this mechanism is that some data cannot be guaranteed to be sent at a certain location. Such a limitation makes it difficult to ensure performance if the existing 5G new air interface design (NR) is directly applied to the unlicensed frequency band. Especially, when the design based on the 5G NR is independently deployed in an unauthorized frequency band, the performance of the system based on the NR is greatly reduced when the service of the unauthorized frequency band is busy because the feedback information cannot be sent in time at a fixed time.
According to the use of 5G NR in an unlicensed frequency band, the design of the system needs to support various scenes, and particularly, the system needs to be independently deployed in the unlicensed frequency band. In order to support independent deployment in the unlicensed frequency band, a terminal device (UE) needs to complete uplink data and control information transmission in the unlicensed frequency band. According to the current NR design and protocol specifications, there are two main ways to send uplink control information: semi-statically configured by high-level information; or dynamically transmitted by Downlink Control Information (DCI) when downlink data is transmitted. The DCI formats 1_0 and 1_1 perform scheduling of PDSCH signals (downlink physical shared channels) and carry information for performing uplink physical control channels (PUCCH signals), as shown in the following table, while the DCI formats are defined in the standard 38.212. As can be seen from the current protocol, the transmission of the existing DCI does not support the scheduling of the direct PUCCH signal.
Therefore, the invention provides a downlink control information transmission method and equipment, solves the problem that the existing DCI transmission does not support the direct PUCCH signal scheduling, and has the advantages of improving the operation efficiency of the whole system, effectively transmitting various downlink control information and indicating the uplink physical control channel to transmit.
