Embodiment Construction
[0079] In order to make the technical problems, technical solutions and advantages to be solved by the present invention clearer, the following will describe in detail with reference to the drawings and specific embodiments.
[0080] Such as figure 1 As shown, an embodiment of the present invention provides a method for transmitting a synchronization signal block, including:
[0081] Step 11, sending a synchronization signal block, which includes: a primary synchronization signal, a secondary synchronization signal, and a physical broadcast channel;
[0082] Wherein, the vacant positions in the synchronization signal block not occupied by the primary synchronization signal, the secondary synchronization signal and the physical broadcast channel are not used for data transmission.
[0083] In the above-mentioned embodiment of the present invention, as figure 2 As shown, the synchronization signal block includes: the primary synchronization signal PSS, the secondary synchroni...

The present invention provides a transmission of a synchronization signal block, a method for measuring cell quality, a base station, and a terminal. The method includes: sending a synchronization signal block, and the synchronization signal block includes: a primary synchronization signal, a secondary synchronization signal, and a physical broadcast channel; Wherein, the vacant positions in the synchronization signal block that are not occupied by the primary synchronization signal, the secondary synchronization signal, and the physical broadcast channel are not used for data transmission; in this embodiment of the present invention, in order to prevent the terminal from being Scheduling to the vacant position of the synchronization signal block for data transmission, so the vacant position of the synchronization signal block is set not to be used for data transmission, so that the cell quality measured by the terminal according to the synchronization signal block is different from the actual cell quality of the terminal in the cell It is more similar to improve the accuracy of cell quality measurement.
Description
technical field [0001] The present invention relates to the field of communication technology, in particular to a transmission of synchronous signal blocks, a method for measuring cell quality, a base station and a terminal. Background technique [0002] In the existing LTE (Long Term Evolution) technology, the terminal equipment UE performs RRM (Radio Resource Management, radio resource management) measurement based on the cell reference symbol (CRS). Perform handover decision and mobility management. [0003] In LTE, CRS is sent in full bandwidth. In order to reduce the overhead of reference symbols, there will be no CRS in 5G, so there is no need to use other reference signals to replace the CRS measurement function. One of the possible ways is to use synchronization symbols for measurement. The transmission method of synchronization symbols in 5G is as follows: figure 1 Shown: the synchronization symbol and the physical broadcast channel PBCH are transmitted in the SS...
