AI Technical Summary
In the prior art, when the uplink data signal sent by the terminal device to the network device is carried on the physical uplink shared channel, the number of resource blocks is small, resulting in fewer subcarriers and a narrower frequency domain bandwidth, which makes it impossible to fully obtain the diversity gain brought by the frequency domain selectivity of the channel.
By distributing N subcarriers across M resource blocks and occupying a portion of the subcarriers in each resource block to transmit uplink data signals, the frequency domain range of the channel is widened, and diversity gain is brought about by the frequency domain selectivity of the channel, thereby improving transmission performance.
This achieves a wider frequency range for PUSCH, fully capturing the frequency-domain selective diversity gain of the channel and improving the transmission performance of uplink data signals.
