Abstract
Official abstract text for this publication.
An information transmission method includes sending, by a terminal, second information and uplink data. The uplink data is sent in a second access mode. The second information indicates a first access mode. The first access mode is useable by the terminal to send the uplink data before the terminal sends the uplink data in the second access mode.
First claim
Opening claim text (preview).
What is claimed is: 1. An information transmission method, wherein the method comprises: sending, by a terminal, second information and uplink data, wherein the uplink data is sent in a second access mode; and the second information indicates a first access mode, and the first access mode is useable by the terminal to send the uplink data before the terminal sends the uplink data in the second access mode. 2. The method according to claim 1 , wherein the second access mode is four-step random access channel (RACH); and the first access mode is one of the following plurality of access modes: contention-free configured grant transmission, contention-based configured grant transmission, or two-step RACH. 3. The method according to claim 1 , wherein the second access mode is early data transmission; and the first access mode is one of the following plurality of access modes: contention-free configured grant transmission, contention-based configured grant transmission, or two-step random access channel with user plane data. 4. The method according to claim 1 , wherein the second access mode is two-step random access channel; and the first access mode is one of the following plurality of access modes: contention-free configured grant transmission, contention-based configured grant transmission. 5. The method according to claim 1 , wherein the method further comprises: sending, by a terminal, third information, wherein the third information is useable to indicate a number of times of sending the uplink data in the first access mode and in the second access mode. 6. The method according to claim 5 , wherein the method further comprises: before the terminal sends the second information and the uplink data, sending, by the terminal, the uplink data and first information in the first access mode, wherein the first information is useable to indicate that a current access mode is an initial access mode. 7. An information transmission method, wherein the method comprises: receiving, by a network device, second information and uplink data, wherein the uplink data is received in a second access mode; and determining, by the network device, a first access mode based on the second information, wherein the first access mode is useable by the terminal to send the uplink data before the terminal sends the uplink data in the second access mode. 8. The method according to claim 7 , wherein the second access mode is four-step random access channel (RACH); and the first access mode is one of the following plurality of access modes: contention-free configured grant transmission, contention-based configured grant transmission, or two-step RACH. 9. The method according to claim 7 , wherein the second access mode is early data transmission; and the first access mode is one of the following plurality of access modes: contention-free configured grant transmission, contention-based configured grant transmission, or two-step random access channel with user plane data. 10. The method according to claim 7 , wherein the second access mode is two-step random access channel; and the first access mode is one of the following plurality of access modes: contention-free configured grant transmission, or contention-based configured grant transmission. 11. The method according to claim 7 , wherein the method further comprises: before the network device receives the second information and the uplink data, receiving, by the network device, the uplink data and first information, wherein the first information is useable to indicate that a current access mode is an initial access mode. 12. The method according to claim 7 , wherein the method further comprises: receiving, by the network device, third information, wherein the third information is useable to indicate a number of times of sending the uplink data in the first access mode and in the second access mode by the terminal. 13. A communication apparatus, wherein the communication apparatus comprises: a transceiver, configured to send second information and uplink data, wherein the uplink data is sent in a second access mode, the second information indicates a first access mode, and the first access mode is useable by the terminal to send the uplink data before the terminal sends the uplink data in the second access mode. 14. The communication apparatus according to claim 13 , wherein the second access mode is four-step random access channel (RACH); and the first access mode is one of the following plurality of access modes: contention-free configured grant transmission, contention-based configured grant transmission, or two-step RACH. 15. The communication apparatus according to claim 13 , wherein the second access mode is early data transmission; and the first access mode is one of the following plurality of access modes: contention-free configured grant transmission, contention-based configured grant transmission, or two-step random access channel with user plane data. 16. The communication apparatus according to claim 13 , wherein the second access mode is two-step random access channel; and the first access mode is one of the following plurality of access modes: contention-free configured grant transmission, or contention-based configured grant transmission. 17. The communication apparatus according to claim 13 , wherein the transceiver is further configured to send third information, wherein the third information is useable to indicate a number of times of sending the uplink data in the first access mode and in the second access mode. 18. The communication apparatus according to claim 17 , wherein the transceiver is further configured to send the uplink data and first information in the first access mode before the transceiver is configured to send the second information and the uplink data, wherein the first information is useable to indicate that a current access mode is an initial access mode.
