Abstract
A method for random access includes that: a terminal device acquires an association between a preamble resource and a physical uplink shared channel (PUSCH) resource; and the terminal device determines, according to the association, a preamble resource and a PUSCH resource used for the terminal device to perform random access. A method for random access includes that: a network device receives a preamble transmitted by a terminal device on a preamble resource, the preamble resource having an association with a physical uplink shared channel (PUSCH) resource; and the network device determines, according to the association between the preamble resource and the PUSCH resource, a PUSCH resource for transmitting a PUSCH by the terminal device. A terminal device and a network device are also provided.
Claims17
A method for random access, comprising:
- acquiring, by a terminal device, an association between at least one preamble resource and at least one physical uplink shared channel (PUSCH) resource;
- and
- determining, by the terminal device according to the association, a preamble resource and a PUSCH resource used for the terminal device to perform random access,
- wherein the association between the at least one preamble resource and the at least one PUSCH resource comprises one of the following:
- one preamble resource corresponds to one PUSCH resource;
- one preamble resource corresponds to a plurality of PUSCH resources;
- a plurality of preamble resources correspond to one PUSCH resource;
- or
- a plurality of preamble resources correspond to a plurality of PUSCH resources,
- wherein the association between the at least one preamble resource and the at least one PUSCH resource is acquired by the terminal device according to a protocol.
A terminal device, comprising:
- a transceiver, configured to acquire an association between at least one preamble resource and at least one physical uplink shared channel (PUSCH) resource;
- and
- a processor, configured to determine, according to the association, a preamble resource and a PUSCH resource used for the terminal device to perform random access,
- wherein the association between the at least one preamble resource and the at least one PUSCH resource comprises one of the following:
- one preamble resource corresponds to one PUSCH resource;
- one preamble resource corresponds to a plurality of PUSCH resources;
- a plurality of preamble resources correspond to one PUSCH resource;
- or
- a plurality of preamble resources correspond to a plurality of PUSCH resources,
- wherein the association between the at least one preamble resource and the at least one PUSCH resource is acquired by the terminal device according to a protocol.
A method for random access, comprising:
- receiving, by a network device, a preamble transmitted by a terminal device on a preamble resource, wherein the preamble resource has an association with at least one physical uplink shared channel (PUSCH) resource;
- and
- determining, by the network device according to the association between the preamble resource and the at least one PUSCH resource, a PUSCH resource for transmitting a PUSCH by the terminal device,
- wherein an association between at least one preamble resource and at least one PUSCH resource comprises one of the following:
- one preamble resource corresponds to one PUSCH resource;
- one preamble resource corresponds to a plurality of PUSCH resources;
- a plurality of preamble resources correspond to one PUSCH resource;
- or
- a plurality of preamble resources correspond to a plurality of PUSCH resources,
- wherein the association between the at least one preamble resource and the at least one PUSCH resource is acquired by the terminal device according to a protocol.
A network device, comprising:
- a transceiver, configured to receive a preamble transmitted by a terminal device on a preamble resource, wherein the preamble resource has an association with at least one physical uplink shared channel (PUSCH) resource;
- and
- a processor, configured to determine, according to the association between the preamble resource and the at least one PUSCH resource, a PUSCH resource for transmitting a PUSCH by the terminal device,
- wherein an association between at least one preamble resource and at least one PUSCH resource comprises one of the following:
- one preamble resource corresponds to one PUSCH resource;
- one preamble resource corresponds to a plurality of PUSCH resources;
- a plurality of preamble resources correspond to one PUSCH resource;
- or
- a plurality of preamble resources correspond to a plurality of PUSCH resources,
- wherein the association between the at least one preamble resource and the at least one PUSCH resource is acquired by the terminal device according to a protocol.
