Data sending method, data receiving method, and related device

A data receiving method, comprising:

• performing, by a network side device, a first operation;
• and
• receiving, by the network side device, target data from a terminal on a first bandwidth part (BWP) based on the first operation, wherein
• the terminal is in an inactive state, the first BWP is an initial uplink BWP configured by the network side device for a reduced capability terminal, and the first operation comprises at least one of the following:
• mapping between a first synchronization signal block (SSB) and a configured grant physical uplink shared channel;
• determining, based on a target object, whether a timing advance used by the configured grant physical uplink shared channel is valid, wherein the target object is a second SSB or a target tracking reference signal;
• or
• determining a target control resource set used for sending the target data, wherein the target control resource set is a control resource set associated with dedicated search space used for monitoring a physical downlink control channel (PDCCH).

A terminal, comprising a processor and a memory, wherein the memory stores a program or instructions that can run on the processor, where the program or the instructions, when executed by the processor, cause the terminal to perform:

• performing a first operation;
• and
• sending, in a case that the terminal is in an inactive state, target data on a first bandwidth part (BWP) based on the first operation, wherein
• the first BWP is an initial uplink BWP configured by a network side device for a reduced capability terminal, and when performing the first operation, the program or the instructions, when executed by the processor, cause the terminal to perform at least one of the following:
• mapping between a first synchronization signal block (SSB) and a configured grant physical uplink shared channel;
• determining, based on a target object, whether a timing advance used by the configured grant physical uplink shared channel is valid, wherein the target object is a second SSB or a target tracking reference signal;
• or
• determining a target control resource set used for sending the target data, wherein the target control resource set is a control resource set associated with dedicated search space used for monitoring a physical downlink control channel (PDCCH).
