Resource allocation indication method, base station, and terminal

A resource allocation indication method applied to a terminal side, comprising:

• receiving resource indication information transmitted by a base station;
• wherein the resource indication information comprises first indication information and second indication information;
• determining target transmission resources corresponding to a target service according to the resource indication information;
• wherein the first indication information is used to indicate one or more bandwidth parts of the target transmission resources, the one or more bandwidth parts are a portion or all of a total bandwidth, the second indication information is used to indicate location information of Physical Resource Blocks (PRBs) allocated to the terminal in PRBs corresponding to the one or more bandwidth parts;
• transmitting the target service through the target transmission resources:
• wherein receiving the resource indication information transmitted by the base station, comprises:
• detecting a periodic group common Physical Downlink Control Channel (group common PDCCH) or first Downlink Control Information (DCI) and receiving the first indication information of the resource indication information transmitted by the base station;
• wherein the first DCI comprises one-stage DCI or any DCI of a two-stage DCI;
• detecting second DCI and receiving the second indication information of the resource indication information transmitted by the base station, wherein the second DCI comprises one-stage DCI or any DCI of a two-stage DCI.

A terminal, comprising:

• a reception circuit, configured to receive resource indication information transmitted by a base station;
• wherein the resource indication information comprises first indication information and second indication information;
• a processing circuit, configured to determine target transmission resources corresponding to a target service according to the resource indication information;
• wherein the first indication information is used to indicate one or more bandwidth parts of the target transmission resources, the one or more bandwidth parts are a portion or all of a total bandwidth, the second indication information is used to indicate location information of Physical Resource Blocks (PRBs) allocated to a terminal in PRBs corresponding to the one or more bandwidth parts;
• a transmission circuit, configured to transmit the target service through the target transmission resources;
• wherein the reception circuit comprises:
• a first reception subcircuit, configured to detect a periodic group common Physical Downlink Control Channel (group common PDCCH) or first Downlink Control Information (DCI) and receive the first indication information of the resource indication information transmitted by the base station;
• wherein the first DCI comprises one-stage DCI or any DCI of a two-stage DCI;
• a second reception subcircuit, configured to detect second DCI and receive the second indication information of the resource indication information transmitted by the base station, wherein the second DCI comprises one-stage DCI or any DCI of a two-stage DCI.
