Problems solved by technology

[0011] Therefore, if only 2 SS blocks can be transmitted on this frequency band due to the limitation of LTE, the coverage of NR cells will be greatly limited, which is not conducive to the deployment of NR.

example 1

[0135] Case 1: Only consider the actual transmission synchronization signal block transmission mode under the coexistence requirements of 5G NR system and LTE:

[0136] L=4, the transmission of the synchronous signal block pulse set of 30KHz, use 2 bits to indicate the transmission position of the actual transmission synchronous signal block;

[0137] Transmission status 1: Indicates that the actual transmission is SS block 1, 2, 3, 4, which is simply expressed as 1111;

[0138] Transmission status 2: 1010, indicating that the first SS block and the third SS block are the synchronization signal blocks actually transmitted, corresponding to the coexistence scenario of 5G NR and 2-port / 1-port CRS LTE;

[0139] Transmission status 3: 1000, corresponding to the coexistence scenario of 5G NR and 4-port CRS LTE;

[0140] You can also consider the state: 1100, so that 2 bits can be used to indicate 4 states;

Abstract

The embodiment of the invention provides indication and receiving methods of a synchronization signal block transmission position, network equipment and a terminal. The indication method includes: sending first indication information, which indicates the transmission resource position of an actually transmitted synchronization signal block, to the terminal. The solution of the invention can indicate the actually transmitted synchronization signal block through a manner of indication, can well exclude transmission of other synchronization signal blocks which do not need to be transmitted, and reduces signaling indication overheads.

Description

technical field [0001] The invention relates to the technical field of communication, in particular to the indication of the transmission position of a synchronous signal block, a receiving method, a network device and a terminal. Background technique [0002] In the 5G standardization discussion, in order to support multi-beam operation, multiple synchronization signal blocks (SS blocks) will be transmitted. Multiple SS blocks form a synchronous signal burst set (SS burst set, synchronous signal pulse set). During a synchronization signal pulse set transmission period (or within a synchronization signal transmission period), the maximum number of SS blocks that may be transmitted on each frequency band and the corresponding positions have been determined so far. [0003] Below 3GHz: L=4, that is, a maximum of 4 SS blocks can be transmitted; the subcarrier spacing may be 15KHz and 30KHz, and the corresponding SS block pattern (synchronization signal block transmission posit...
