Title:
COMMUNICATION METHOD, APPARATUS, AND SYSTEM
Document Type and Number:
WIPO Patent Application WO/2023/131220
Kind Code:
A1
Abstract:
Provided in the present application are a communication method, apparatus, and system. The method may comprise: receiving a random access response message, wherein the random access response message is used for indicating a first uplink grant; determining a first hybrid automatic repeat request (HARQ) state, wherein the first HARQ state is the HARQ state of a first HARQ process, and the first HARQ process is a HARQ process which is used for transmitting data on the first uplink grant; determining a second HARQ state, wherein the second HARQ state is a HARQ state which is allowed to be used when data in a first logical channel is transmitted; and when the first HARQ state is different from the second HARQ state, transmitting the data in the first logical channel on the first uplink grant by means of the first HARQ process and by using the first HARQ state. When the HARQ state of a logical channel does not match the HARQ state of a HARQ process 0, applying the method can avoid a communication interruption and achieve normal transmission of data, thereby improving the communication reliability.
