Abstract
This application provides a random access method, a terminal, and a network device. The random access method includes: determining, by a terminal, whether a resource used for random access conflicts with a resource used for receiving a downlink signal; and if the resource used for the random access conflicts with the resource used for the downlink signal, preferentially using the conflicting random access resource for receiving the downlink signal but not for the random access.
Claims34
A method comprising:
- receiving, by a terminal, information about random access resources from a network device;
- determining, by the terminal, that a first random access resource is available in a first slot based on the information about the random access resources and a time resource for receiving a synchronization signal block, the first random access resource in the first slot being after the time resource for receiving the synchronization signal block in the first slot in a time domain;
- and
- sending, by the terminal, a random access preamble to the network device based on the first random access resource.
An apparatus, comprising:
- one or more memories configured to store instructions;
- and
- one or more processors coupled to the one or more memories, and configured to execute the instructions to cause the apparatus to:
- receive information about random access resources from a network device;
- determine that a first random access resource is available in a first slot based on the information about the random access resources and a time resource for receiving a synchronization signal block, the first random access resource in the first slot being after the time resource for receiving the synchronization signal block in the first slot in a time domain;
- and
- send a random access preamble to the network device based on the first random access resource.
A method, comprising:
- configuring, by a network device, information about a random access resource to a terminal;
- configuring, by the network device, information about a synchronization signal block to the terminal;
- and
- receiving, by the network device, a random access preamble from the terminal on the random access resource in a slot, wherein the random access resource in the slot is after a time resource for the synchronization signal block in the slot in a time domain.
An apparatus, comprising:
- one or more memories configured to store instructions;
- and
- one or more processors coupled to the one or more memories, and configured to execute the instructions to cause the apparatus to:
- configure information about a random access resource to a terminal;
- configure information about a synchronization signal block to the terminal;
- and
- receive a random access preamble from the terminal on the random access resource in a slot, wherein the random access resource in the slot is after a time resource for the synchronization signal block in the slot in a time domain.
A non-transitory computer readable medium, wherein the non-transitory computer readable medium stores instructions that are executable by a computer, and the instructions comprise instructions for:
- receiving information about random access resources from a network device;
- determining that a first random access resource is available in a first slot based on the information about the random access resources and a time resource for receiving a synchronization signal block;
- wherein the first random access resource in the first slot is after the time resource for receiving the synchronization signal block in the first slot in a time domain;
- and
- sending a random access preamble to the network device based on the first random access resource.
A non-transitory computer readable medium, wherein the non-transitory computer readable medium stores instructions that are executable by a computer, and the instructions comprise instructions for:
- configuring information about a random access resource to a terminal;
- configuring information about a synchronization signal block to the terminal;
- and
- receiving a random access preamble from the terminal on the random access resource in a slot;
- and
- wherein the random access resource in the slot is after a time resource for the synchronization signal block in the slot in a time domain.
A system, comprising:
- a network device and a terminal;
- the network device being configured to:
- configure information about random access resources to the terminal;
- configure information about a synchronization signal block to the terminal;
- and
- receive a random access preamble from the terminal on a first random access resource in the random access resources in a first slot;
- wherein the first random access resource in the first slot is after a time resource for the synchronization signal block in the first slot in a time domain;
- the terminal being configured to:
- receive the information about the random access resources from the network device;
- determine that the first random access resource is available in the first slot based on the information about the random access resources and the time resource for receiving the synchronization signal block in the first slot;
- and
- send the random access preamble to the network device based on the first random access resource.
