Problems solved by technology

[0004] Just because jumping back and forth between the anchor subband and other subbands requires more operations, it is very power-consuming for the narrowband user equipment to jump back to the anchor subband for time-frequency tracking (synchronization) and beam tracking, and the system low efficiency

Abstract

The present invention provides a partial bandwidth wireless transmission method, device, base station and user equipment. The method includes: configuring a first common control channel transmitted on the anchor subband; configuring at least one other subband other than the anchor subband, and a second common control channel transmitted on the other subband; scheduling at least a part of bandwidth user equipment to the other subbands, and send the configuration of the second common control channel and the other subbands to the user equipment; obtain the sending timing of the synchronization signal block in the anchor subband, according to the The timing for sending the synchronization signal block is to send the second common control channel to the other subbands at the same time, and the second common control channel includes a reference signal for demodulation. The invention enables the user equipment to use part of the bandwidth in the large system bandwidth to transmit and receive data, and at the same time achieves the effect of improving system efficiency.

Description

technical field [0001] The present invention relates to the technical field of wireless communication, in particular to a partial bandwidth wireless transmission method, device, base station and user equipment. Background technique [0002] In the current 5G system, the system bandwidth of a single carrier will be greatly increased, for example, a single carrier may have a bandwidth of 100 MHz in a frequency band less than 6 GHz. The user equipment can directly use the 100MHz bandwidth, but this will lead to work at a higher sampling rate, such as 153.6Msps, which will cause high power consumption. In some scenarios, the user equipment can use a narrow bandwidth for data transmission and reception, for example, in a small data packet, or in a power saving mode, or the user equipment itself is a low-cost terminal, and so on. In these scenarios, the user equipment uses a relatively narrow bandwidth, such as 20MHz, and its own sampling rate is greatly reduced, such as 30.72Msp...
