- the SPS configuration number can be N bits.
- the value of N depends on the number of sets of SPS configurations for a service. For example, if a service requires 2 sets of SPS configurations, then the value of N can be 2 bits. Identify the first set of SPS configurations with 00, identify the reconfiguration for the first set of SPS configurations with 01, identify the second set of SPS configurations with 10, and identify the reconfiguration for the second set of SPS configurations with 11.

- Implicit release For an SPS configuration, the terminal uses the padding BSR with no data part to continuously notify the network side device to release the SPS configuration configured for the terminal by using the corresponding frequency domain resource of the SPS.
- the base station can release all uplink SPS frequency domain resources configured for the service through the PDCCH scrambled by the SPS C-RNTI.

- the terminal determines a set of SPS configurations according to the SPS cycle 1 and the SPS frequency domain resource configuration information A, and determines another set of SPS configurations according to the SPS cycle 2 and the SPS frequency domain resource configuration information A.
- the network side device may also determine multiple SPS configurations configured for the terminal. For the manner in which the network side device determines the multiple sets of SPS configurations configured for the terminal, refer to step 3.

- the T1 position overlaps with the SP1 frequency domain resource at the T1+500ms position, and the SPS configuration 2 is selected according to the maximum SPS frequency domain resource block. Since the other locations do not overlap with the SPS frequency domain resources, the SPS frequency domain resources that can be used are selected.
- Step 5 The receiver detects the SPS.
- the SPS frequency domain resource selected in the time domain overlap position is selected: the corresponding SPS is selected according to the actual data transmission requirement. Frequency domain resource block.
- the receiving end can predict the size of the SPS frequency domain resource block used by the transmitting end (for example, according to information such as a service model), Then, SPS data reception can be performed according to the SPS frequency domain resource block size used by the prediction terminal. Otherwise, multiple sets of SPS configurations need to be blindly detected.
