20250081234
The present disclosure relates to a field of wireless communication technologies, and more particularly relates to a method and an apparatus for determining a channel access mode, and a readable storage medium.
In wireless communication technology, for example, in a 5th generation mobile communication technology (5G), on an unlicensed spectrum, a transmitting end generally needs to monitor a channel before occupying the channel to send data, that is, performing a clear channel assessment (CCA). After the transmitting end performs the clear channel assessment, if it determines that the channel is idling, it can occupy the channel to send and receive data. A maximum channel occupy time (MCOT) is stipulated by a protocol or configured/indicated by a base station; if it is determined that the channel is already occupied, the channel cannot be occupied. This process is generally referred to as a channel access mechanism of listen before talk (LBT) on an unlicensed frequency band. The LBT can also be divided into different types according to specific channel access parameters.
On the unlicensed spectrum, a LBT-free channel access mode can also be used, that is, the transmitting end can directly occupy the channel without channel monitoring.

In some implementations, the above solution may also include default configuration information of the UE. The default configuration information may be configuration information with a lowest priority, and the default configuration information is used only when the UE does not receive the configuration information sent by the base station.
In some implementations, a priority of the DCI carrying the channel access mode is higher than a priority of the RRC dedicated signaling carrying the channel access mode.
In an example, the user equipment receives two configuration information carrying the channel access modes from the network device, which are respectively the DCI carrying the channel access mode and the RRC dedicated signaling carrying the channel access mode, and then determines that the DCI is the first configuration information, thereby determining that the channel access mode carried by the DCI is the channel access mode of the user equipment.
For example, the user equipment receives an RRC dedicated signaling carrying the second channel access mode (Type 2 channel access) and a DCI for scheduling a PUSCH carrying the third channel access mode (No-LBT) from the network device, and determines that the DCI is the first configuration information and determines that the third channel access mode (No-LBT) carried in the DCI is the channel access mode of the user equipment.

In some implementations, a priority of the RRC dedicated signaling carrying the channel access mode is higher than that of the system information carrying the channel access mode.
In an example, the user equipment receives two configuration information carrying the channel access modes from the network device, which are respectively the RRC dedicated signaling carrying the channel access mode and the system information carrying the channel access mode, and then determines that the RRC dedicated signaling is the first configuration information, thereby determining that the channel access mode carried in the RRC dedicated signaling is the channel access mode of the user equipment.
For example, the user equipment receives system information carrying the first channel access mode (Type 1 channel access) and an RRC dedicated signaling carrying the third channel access mode (No-LBT) from the network device, and determines that the RRC dedicated signaling is the first configuration information and determines that the third channel access mode (No-LBT) carried in the RRC dedicated signaling is the channel access mode of the user equipment.
For example, the user equipment receives system information carrying a second channel access mode (Type 2 channel access) and an RRC dedicated signaling carrying a third channel access mode (No-LBT) from the network device, and determines that the RRC dedicated signaling is the first configuration information and determines that the third channel access mode (No-LBT) carried in the RRC dedicated signaling is the channel access mode of the user equipment.
In some implementations, a priority of the DCI carrying the channel access mode is higher than a priority of the RRC dedicated signaling carrying the channel access mode, and a priority of the RRC dedicated signaling carrying the channel access mode is higher than that of the system information carrying the channel access mode.
That is, an order of the priorities of the three configuration information from high to low is: the DCI carrying the channel access mode, the RRC dedicated signaling carrying the channel access mode, and the system information carrying the channel access mode.
In an example, the user equipment receives three configuration information carrying the channel access modes from the network device, which are respectively the DCI carrying the channel access mode, the RRC dedicated signaling carrying the channel access mode, and the system information carrying the channel access mode, and determines that the DCI is the first configuration information, thereby determining that the channel access mode carried in the DCI is the channel access mode of the user equipment.
For example, the user equipment receives a DCI for scheduling a PUSCH carrying the first channel access mode (Type 1 channel access), an RRC dedicated signaling carrying the second channel access mode (Type 2 channel access) and system information carrying the third channel access mode (No-LBT) from the network device, and determines that the DCI is the first configuration information, and determines that the first channel access mode (Type 1 channel access) carried in the DCI is the channel access mode of the user equipment.

In some implementations, the second configuration information is preset configuration information. That is, which configuration information is the second configuration information is pre-configured for the UE; when the UE receives at least two pieces of configuration information, it can determine which configuration information is the second configuration information. In some other implementations, the second configuration information is configuration information determined by a protocol. That is, the UE can determine which configuration information is the second configuration information according to the communication protocol. When the UE receives at least two pieces of configuration information, it can determine which configuration information is the second configuration information. In some implementations, the second configuration information is configuration information with a highest priority.
In some implementations, the second configuration information is the configuration information with the highest priority among the downlink control information (DCI) carrying the channel access mode, the RRC dedicated signaling carrying the channel access mode, and the system information carrying the channel access mode. In some implementations, the above solution may also include default configuration information of the UE. The default configuration information may be the configuration information with the highest priority, and the default configuration information is used only when the UE does not receive the configuration information sent by the base station.
In some implementations, the second configuration information is the DCI carrying the channel access mode. Therefore, when the at least two pieces of configuration information include the DCI carrying the channel access mode, it is determined that the DCI carrying the channel access mode is the first configuration information, and it is determined that the channel access mode of the user equipment is the channel access mode carried in the DCI.
In some implementations, in response to the at least two pieces of configuration information including the downlink control information (DCI) carrying the channel access mode, it is determined that the DCI is the first configuration information, and it is determined that the channel access mode of the user equipment is the channel access mode carried in the DCI.

That is, which configuration information is the third configuration information is pre-configured for the UE. When the UE receives at least two pieces of configuration information, it can determine which configuration information is the third configuration information. In some other implementations, the third configuration information is configuration information determined by a protocol. That is, the UE can determine which configuration information is the third configuration information according to the communication protocol; and when the UE receives at least two pieces of configuration information, it can determine which configuration information is the third configuration information.
