Method for obtaining initial bandwidth part configuration, terminal, and network-side device

A method for configuring an initial bandwidth part, comprising:

• transmitting, by a network-side device, configuration information of a first initial BWP in target system information associated with a CD-SSB;
• wherein
• the first initial BWP is an initial BWP configured by the network-side device for a first target terminal, and a bandwidth of the first initial BWP does not exceed a maximum bandwidth capability supported by the first target terminal;
• the method further comprises:
• in a case that the network-side device configures no first target search space set for the first initial BWP, performing, by the first target terminal, at least one of monitoring on a first control channel of the first target search space set on a second initial BWP and reception of a first control channel of the first target search space set on a second initial BWP, wherein the second initial BWP is an initial BWP configured by the network-side device for a second target terminal;
• and
• performing, based on a first control channel detected, reception of a first data channel scheduled by the first control channel.

A terminal, comprising;

• a processor, a memory, and a program or instructions stored in the memory and capable of running on the processor, wherein when the program or the instructions are executed by the processor, the following steps of a method for obtaining an initial bandwidth part configuration are implemented:
• monitoring, by a first target terminal, a cell-defining synchronization signal block CD-SSB and obtaining target system information associated with the CD-SSB;
• obtaining, by the first target terminal by decoding the target system information, a first initial bandwidth part BWP configured by a network-side device, wherein the first initial BWP is an initial BWP configured by the network-side device for the first target terminal, and a bandwidth of the first initial BWP does not exceed a maximum bandwidth capability supported by the first target terminal;
• in a case that the network-side device configures no first target search space set for the first initial BWP, performing, by the first target terminal, at least one of monitoring on a first control channel of the first target search space set on a second initial BWP and reception of a first control channel of the first target search space set on a second initial BWP, wherein the second initial BWP is an initial BWP configured by the network- side device for a second target terminal;
• and
• performing, based on a first control channel detected, reception of a first data channel scheduled by the first control channel.
