Information processing method and related device
A method for processing information is provided. The method includes that a base station transmits downlink control information (DCI) to a terminal. The DCI includes a first indication field. The first indication filed is configured to carry response information of hybrid automatic repeat request (HARQ). The DCI further includes a second indication field configured to carry a trigger notification of random access or early data transmission (EDT). Furthermore, the terminal determines the response information of the HARQ based on the first indication field in the DCI, and determines the trigger notification of random access or EDT based on a second indication field when the DCI includes the second indication field.
1. A method for processing information, comprising:
transmitting, by a base station, Downlink Control Information (DCI), wherein the DCI comprises a first indication field configured to carry response information of Hybrid Automatic Repeat Request (HARQ); and
in response to determining that the DCI comprises a second indication field, configured, by the base station, to carry a trigger notification indicating random access or Early Data Transmission (EDT);
wherein in response to determining that the DCI does not comprise the second indication field, the DCI is configured to trigger a terminal to perform new data transmission or data retransmission on a reserved resource.
2. The method of claim 1 , wherein,
in response to the first indication field indicating that the response information is an acknowledgement character (ACK), the DCI carries the second indication field; or
in response to the first indication field indicating that the response information is a non- acknowledgement character (NACK), the DCI carries the second indication field.
3. The method of claim 2 , wherein in response to the first indication field indicating that the response information is the ACK, configuring the DCI to trigger a terminal to perform the random access or EDT-based network connection based on the second indication field in response to transmitting new data; or
in response to the first indication field indicating that the response information is the NACK, configuring the DCI to trigger the terminal to perform the random access or the EDT-based network connection based on the trigger notification in response to retransmitting data.
4. The method of claim 1 , wherein in response to determining that the DCI comprises the second indication field, determining that the DCI further comprises a third indication field,
wherein the third indication field is configured to indicate a random access type, and the random access type comprises contention-based random access and contention-free random access.
5. The method of claim 4 , wherein,
in response to the third indication field indicating that the random access type is the contention-based random access, the DCI is further configured to indicate an initial coverage enhancement level; or
in response to the third indication field indicating that the random access type is the contention-free random access, the DCI is further configured to indicate a preamble index, a physical random access channel mask index, and an initial coverage enhancement level.
6. A method for processing information, comprising:
receiving, by a terminal, Downlink Control Information (DCI);
determining, by the terminal, response information of Hybrid Automatic Repeat Request (HARQ) based on a first indication field contained in the DCI;
in response to determining the DCI comprises a second indication field, determining, by the terminal, a trigger notification indicating random access or Early Data Transmission (EDT) based on the second indication field; and
in response to determining that the DCI does not comprise the second indication field and the first indication field indicates the ACK, performing new data transmission on a reserved resource; or in response to determining that the DCI does not comprise the second indication field and the first indication field indicates the NACK, performing data retransmission on the reserved resource.
7. The method of claim 6 , wherein
in response to the first indication field indicating that the response information is an acknowledgement character (ACK), the DCI carries the second indication field; or
in response to the first indication field indicating that the response information is a non- acknowledgement character (NACK), the DCI carries the second indication field.
8. The method of claim 7 , further comprising:
in response to the first indication field indicating that the response information is the ACK, performing the random access or EDT-based network connection of new data transmission based on the second indication field; or
in response to the first indication field indicating that the response information is the NACK, performing the random access or EDT-based network connection of data retransmission based on the second indication field.
9. The method of claim 6 , wherein in response to determining that the DCI comprises the second indication field, determining that the DCI further comprises a third indication field;
the method further comprises:
determining a random access type based on the third indication field, wherein the random access type comprises contention-based random access and contention-free random access.
10. The method of claim 9 , further comprising:
in response to the third indication field indicating that the random access type is the contention-based random access, determining an initial coverage enhancement level based on the DCI; or
in response to the third indication field indicating that the random access type is the contention-free random access, determining a preamble index, a physical random access channel mask index, and an initial coverage enhancement level based on the DCI.
11. A user equipment (UE), comprising:
a memory, and
a processor, wherein when computer-executable instructions stored in the memory are executed by the processor, the processor is configured to:
receive Downlink Control Information (DCI);
determine response information of Hybrid Automatic Repeat Request (HARQ) based on a first indication field contained in the DCI;
determine a trigger notification indicating random access or Early Data Transmission (EDT) based on a second indication field in response to determining that the DCI comprises the second indication field; and
in response to determining that the DCI does not comprises the second indication field and the first indication field indicates the ACK, perform new data transmission on a reserved resource;
or in response to determining that the DCI does not comprise the second indication field and the first indication field indicates the NACK, perform data retransmission on the reserved resource.
12. The UE of claim 11 , wherein
in response to the first indication field indicating that the response information is an acknowledgement character (ACK), the DCI carries the second indication field; or
in response to the first indication field indicating that the response information is a non-acknowledgement character (NACK), the DCI carries the second indication field.
13. The UE of claim 12 , wherein the processor is further configured to:
in response to the first indication field indicating that the response information is the ACK, perform the random access or EDT-based network connection of new data transmission based on the second indication field; or
in response to the first indication field indicating that the response information is the NACK, perform the random access or EDT-based network connection of data retransmission based on the second indication field.
14. The UE of claim 11 , wherein the processor is further configured to:
