Description

Uplink transmission method, resource indication method, terminal and network equipment
Technical Field
The present invention relates to the field of communications technologies, and in particular, to an uplink transmission method, a resource indication method, a terminal, and a network device.
Background
At present, in order to meet the regulatory requirement of OCB (occupied Channel Bandwidth), that is, the requirement of occupying 80% of the spectrum of the transmission Bandwidth, when a terminal such as a UE (User Equipment) transmits uplink, the transmission power is limited, and the whole band cannot be occupied, so that an interlace (interlace) structure can be adopted to Occupy more than 80% of the Bandwidth. The interleaving structure is to spread RBs (Resource blocks) in an uplink bandwidth occupied by the UE over the entire bandwidth, and the transmission waveform of the interleaving structure occupies almost the entire bandwidth from the perspective of the UE.
For an L TE (L ong Term Evolution ) system, the uplink bandwidth may be 20MHz or 10MHz, the 20MHz bandwidth includes 100 PRBs (Physical Resource blocks, which are equivalent to RBs), and the 10MHz bandwidth includes 50 PRBs.
In an NR (New Radio, New air interface) system, uplink bandwidths with different sizes and different SCS (subcarrier spacing) can be supported, and the number of PRBs available in the same or different uplink bandwidths may be different according to different situations.
However, in the current NR system, when the UE transmits uplink signals, each SCS is usually matched to correspond to an interleaving structure, resulting in low resource utilization.
