Abstract
A random access method and a related apparatus are provided in implementations of the present disclosure and are applicable to a user equipment (UE). The method includes the following. A first bandwidth part (BWP) is selected from multiple BWPs, where the multiple BWPs are configured by a network device. A first physical random access channel (PRACH) resource corresponding to a first synchronization signal block (SSB) is determined. A random access preamble is transmitted on the first BWP based on the first PRACH resource.
Claims12
A random access method, being applicable to a user equipment (UE) in an idle state or an inactive state, and comprising:
- selecting a first bandwidth part (BWP) from a plurality of BWPs, the plurality of BWPs being configured by a network device;
- determining a first physical random access channel (PRACH) corresponding to a first synchronization signal block (SSB);
- and
- transmitting a random access preamble on the first BWP based on the first PRACH resource;
- wherein selecting the first BWP from the plurality of BWPs comprises:
- selecting the first BWP corresponding to a service type of the UE from the plurality of BWPs based on a correspondence between service types and BWPs, wherein the correspondence between service types and BWPs is configured by the network device;
- and
- selecting the first BWP from the plurality of BWPs based on first selection factor information, wherein the first selection factor information is configured by the network device, wherein the plurality of BWPs comprises an initial BWP, and the first selection factor information indicates a selection factor of the initial BWP and indicates that BWPs among the plurality of BWPs other than the initial BWP each have a same selection factor.
A user equipment (UE) in an idle state or an inactive state comprising:
- a processor;
- a transceiver;
- and
- a memory configured to store computer programs, wherein the processor is configured to invoke and execute the computer programs stored in the memory to:
- select a first bandwidth part (BWP) from a plurality of BWPs, the plurality of BWPs being configured by a network device;
- determine a first physical random access channel (PRACH) resource corresponding to a first synchronization signal block (SSB);
- and
- cause the transceiver to transmit a random access preamble on the first BWP based on the first PRACH resource;
- wherein the processor configured to select the first BWP from the plurality of BWPs is configured to:
- select the first BWP corresponding to a service type of the UE from the plurality of BWPs based on a correspondence between service types and BWPs, wherein the correspondence between service types and BWPs is configured by the network device;
- and
- select the first BWP from the plurality of BWPs based on first selection factor information, wherein the first selection factor information is configured by the network device, wherein the plurality of BWPs comprises an initial BWP, and the first selection factor information indicates a selection factor of the initial BWP and indicates that BWPs among the plurality of BWPs other than the initial BWP each have a same selection factor.
