Abstract
A method for random access includes: generating configuration information related to a physical random access channel, the configuration information including information of correspondence between a preamble and a physical uplink shared channel (PUSCH) group, where the PUSCH group carries a first step request message in a two-step random access, and one or more preambles correspond to one PUSCH group; and sending the configuration information to user equipment (UE).
Claims20
A method for random access, applied to a base station and comprising:
- generating configuration information related to a physical random access channel, the configuration information comprising information of correspondence between a preamble and a physical uplink shared channel (PUSCH) group, wherein the PUSCH group carries a first step request message in a two-step random access, and wherein one or more preambles correspond to one PUSCH group;
- and
- sending the configuration information to user equipment.
A method for random access, applied to user equipment and comprising:
- receiving configuration information related to a physical random access channel from a base station, the configuration information comprising information of correspondence between a preamble and a physical uplink shared channel (PUSCH) group, wherein the PUSCH group carries a first step request message in a two-step random access, and one or more preambles correspond to one PUSCH group;
- determining a preamble and a corresponding PUSCH group according to the information of correspondence when random access is required;
- and
- sending the first step request message in the two-step random access according to the determined preamble and the corresponding PUSCH group.
User equipment (UE), comprising:
- one or more processors;
- and
- memory for storing instructions executable by the one or more processors;
- wherein the one or more processors are configured to:
- receive configuration information related to a physical random access channel from a base station, the configuration information comprising information of correspondence between a preamble and a physical uplink shared channel (PUSCH) group, wherein the PUSCH group carries a first step request message in a two-step random access, and one or more preambles correspond to one PUSCH group;
- determine a preamble and a corresponding PUSCH group according to the information of correspondence when random access is required;
- and
- send the first step request message in the two-step random access according to the determined preamble and the corresponding PUSCH group.
