Abstract
A wireless communication method, a terminal device, and a network device are disclosed. The method includes: a terminal device sends a first message to a network device, the first message including a preamble for a random access and an uplink message; the terminal device monitors a PDCCH scrambled by a target RNTI; and according to a second message scheduled by the PDCCH and the uplink message, determines whether the contention collision is solved.
Claims10
A wireless communication method, comprising:
- sending, by a terminal device, a first message to a network device, wherein the first message comprises a preamble for a random access and an uplink message;
- monitoring, by the terminal device, a physical downlink control channel (PDCCH) scrambled by a target radio network temporary identity (RNTI);
- and
- determining whether a contention conflict is resolved according to a second message scheduled by the PDCCH and the uplink message;
- wherein determining whether the contention conflict is resolved according to the second message scheduled by the PDCCH and the uplink message comprises:
- determining that the contention conflict is not resolved when the second message does not comprise a contention resolution identity (ID);
- wherein when the second message comprises a Backoff Indicator (BI) and a random access preamble identity (RAPID), the method further comprises:
- determining to send a third message when there is the RAPID consistent with the preamble in the first message.
5 more elements
A wireless communication method, comprising:
- receiving, by a network device, a first message sent by a terminal device, wherein the first message comprises a preamble for a random access and an uplink message;
- and
- determining, by the network device, a second message for replying to the terminal device according to a decoding situation of the first message;
- wherein determining, by the network device, the second message for replying to the terminal device according to the decoding situation of the first message comprises:
- sending, by the network device, the second message to the terminal device when decoding of the preamble is successful and decoding of the uplink message is failed, wherein the second message does not comprise a contention resolution identity (ID), but comprises a Backoff Indicator (BI) and a random access preamble identity (RAPID);
- wherein the terminal device is configured to send a third message when there is the RAPID consistent with the preamble in the first message.
3 more elements
A terminal device, comprising:
- a processor and a transceiver, wherein
- the transceiver is configured to send a first message to a network device, wherein the first message comprises a preamble for a random access and an uplink message;
- and
- monitor a physical downlink control channel (PDCCH) scrambled by a target radio network temporary identity (RNTI);
- the processor is configured to determine whether a contention conflict is resolved according to a second message scheduled by the PDCCH and the uplink message;
- wherein the processor is specifically configured to:
- determine that the contention conflict is not resolved when the second message does not comprise a contention resolution identity (ID);
- wherein when the second message comprises a Backoff Indicator (BI) and a random access preamble identity (RAPID), the processor is further configured to:
- determining to send a third message when there is the RAPID consistent with the preamble in the first message.
6 more elements
A network device, comprising:
- a processor and a transceiver, wherein
- the transceiver is configured to receive a first message sent by a terminal device, wherein the first message comprises a preamble for a random access and an uplink message;
- and
- the processor is configured to determine a second message for replying to the terminal device according to a decoding situation of the first message;
- wherein the transceiver is further configured to:
- send a second message to the terminal device when decoding of the preamble is successful and decoding of the uplink message is failed;
- wherein the second message does not comprise a contention resolution identity (ID), but comprises a Backoff Indicator (BI) and a random access preamble identity (RAPID) for the terminal device determining to send a third message when there is the RAPID consistent with the preamble in the first message.
