The present application is a US National Stage of International Application No. PCT/CN2014/072534, filed Feb. 26, 2014, designating the United States, and claiming the benefit of Chinese Patent Application No. 201310116409.5, filed with the State Intellectual Property Office of People's Republic of China on Apr. 3, 2013 and entitled “Method and device for transmitting uplink-downlink configuration information”, which is hereby incorporated by reference in its entirety.
The present disclosure relates to the field of communications and particularly to a method and device for transmitting uplink-downlink configuration information.
Downlink Control Information (DCI) is carried over a Physical Downlink Control Channel (PDCCH) to effectively transmit uplink or downlink scheduling information and related common control information. 10 DCI formats have been defined so far in the Long Term Evolution (LTE) system. Main functions of the respective DCI formats can be as depicted in Table 1. Moreover in a DCI channel encoding procedure, firstly a Cyclic Redundancy Check (CRC) is performed on and CRC information is added to DCI bits, and then the CRC information is scrambled by a Radio Network Temporary Identifier (RNTI), and next the DCI bits are channel-encoded, and the channel-encoded DCI bits are matched in rate.
In order to make the technical solutions of the disclosure more apparent, the drawings to which reference is made in the description of the embodiments will be described below briefly, and apparently the drawings in the description below merely illustrate some embodiments of the disclosure, but those ordinarily skilled in the art can further derive from these drawings other drawings without any inventive effort. In the drawings:
FIG. 1 is a schematic diagram of the handling procedure at the physical layer in the prior art;
FIG. 2 is a schematic diagram of PDCCH blind detection in the prior art;
The technical solutions in the disclosure will be described below clearly and fully with reference to the drawings in the disclosure, and apparently the embodiments to be described below are only a part but not all of the embodiments of the disclosure. All the other embodiments that can be derived by those ordinarily skilled in the art based upon the embodiments here of the disclosure without any inventive effort shall fall into the claimed scope of the disclosure.
In view of the problem in the prior art, an embodiment of the disclosure provides a method for transmitting uplink-downlink configuration information, which can be TDD uplink-downlink configuration information. As illustrated in FIG. 4, the method includes the following operations:
In the operation 401, a network device generates DCI including TDD uplink-downlink configuration information. The network device can be a base station, an eNB, a Radio Network Controller (RNC), etc.
