Abstract
Embodiments of the present disclosure provide an access control method and device. The method comprises: obtaining a RO resource for PRACH transmission and a PO resource for Msg A PUSCH transmission on the channel (Step S1001); determining a first channel access procedure for PRACH transmission and a second channel access procedure for Msg A PUSCH transmission (Step S1002), wherein the first channel access procedure comprises: a channel access procedure to initiate a first COT; or, a channel access procedure to share a second COT initiated by a network device, if the RO resource is within the second COT.
Claims19
A method of accessing to a channel in shared spectrum, comprising:
- obtaining, by a terminal device, a random access channel (RACH) occasion (RO) resource for physical random access channel (PRACH) transmission and a physical uplink shared channel (PUSCH) occasion (PO) resource for Message A (Msg A) PUSCH transmission on the channel;
- and
- determining, by the terminal device, a first channel access procedure for PRACH transmission and a second channel access procedure for Msg A PUSCH transmission,
- wherein the first channel access procedure comprises:
- a channel access procedure to initiate a first channel occupancy time (COT);
- or,
- a channel access procedure to share a second COT initiated by a network device, if the RO resource is within the second COT,
- wherein the second channel access procedure comprises a channel access procedure to share the first COT initiated by the terminal device, if the PO resource is within the first COT, and
- wherein that the PO resource is within the first COT comprises:
- the RO resource and the PO resource are within the maximum channel occupancy time (MCOT) corresponding to the first COT.
A terminal device, comprising:
- a processor;
- a memory configured to store instructions executable by the processor,
- wherein the processor is configured to execute operations comprising:
- obtaining a random access channel (RACH) occasion (RO) resource for physical random access channel (PRACH) transmission and a physical uplink shared channel (PUSCH) occasion (PO) resource for Message A (Msg A) PUSCH transmission on the channel;
- and
- determining a first channel access procedure for PRACH transmission and a second channel access procedure for Msg A PUSCH transmission,
- wherein the first channel access procedure comprises:
- a channel access procedure to initiate a first channel occupancy time (COT);
- or,
- a channel access procedure to share a second COT initiated by a network device, if the RO resource is within the second COT,
- wherein the second channel access procedure comprises a channel access procedure to share the first COT initiated by the terminal device, if the PO resource is within the first COT, and
- wherein that the PO resource is within the first COT comprises:
- the RO resource and the PO resource are within the maximum channel occupancy time (MCOT) corresponding to the first COT.
