Description

Technical Field

[0001] The present disclosure relates to the field of wireless communication technologies, and in particular to a method, device, and readable storage medium for determining a channel access mode. Background Art

[0002] In wireless communication technology, such as the fifth generation mobile communication technology (5G), in unlicensed spectrum, the transmitter generally needs to monitor the channel before occupying the channel to send data, that is, perform a clear channel assessment (CCA). After the transmitter performs the clear channel assessment, if it determines that the channel is idle, it can occupy the channel to send and receive data. The maximum channel occupation time (MCOT) is determined by the protocol or configured / indicated by the base station; if it is determined that the channel is occupied, it cannot occupy the channel. This process is generally called the listen before talk (LBT) channel access mechanism on the unlicensed frequency band. LBT can also be divided into different types according to the specific channel access parameters.

[0003] In unlicensed spectrum, an LBT-free channel access method can also be used, that is, the transmitter does not need to monitor the channel and can directly occupy the channel.

[0004] The network device may use different methods to indicate the channel access method adopted by the UE. When the network device indicates multiple channel access methods, how the UE determines the channel access method is a problem that needs to be solved. Summary of the Invention

[0075] The present disclosure provides a method for determining a channel access mode. Figure 2 FIG. 1 is a flow chart showing a method for determining a channel access mode according to an exemplary embodiment. Figure 2 As shown, the method includes:

[0076] In step S201 , the network device 101 sends at least two pieces of configuration information carrying a channel access mode to the user equipment 102 .

[0077] In step S202 , the user equipment 102 receives at least two pieces of configuration information carrying a channel access mode from the network device 101 .

[0081] Type 1 channel access corresponds to a channel access method that performs N channel monitoring operations, where N is an initial value generated by the UE according to the Type 1 channel access method specification and is an integer greater than zero. The value of N can be 1 or greater.

[0082] The second type of channel access, or Type 2 channel access, corresponds to a channel access method that performs channel monitoring only once.

[0083] The third type of channel access, or Type 3 channel access, corresponds to the channel access method without channel monitoring, that is, no channel monitoring is required, but the channel can be accessed directly.

Therefore, when the user device receives multiple channel access methods indicated by the network device, it determines a reasonable channel access method from them, and uses this reasonable channel access method to perform channel access, thereby saving power consumption of the user device while ensuring and improving communication efficiency.

[0093] The present disclosure provides a method for determining a channel access mode, which is executed by a user equipment. Figure 3 FIG. 1 is a flow chart showing a method for determining a channel access mode according to an exemplary embodiment. Figure 3 As shown, the method includes:

[0097] In some possible implementations, the channel access mode includes at least one of the following:

[0098] Type 1 channel access corresponds to a channel access method that performs N channel monitoring operations, where N is an initial value generated by the UE according to the Type 1 channel access method specification and is an integer greater than zero. The value of N can be 1 or greater.

[0099] The second type of channel access, or Type 2 channel access, corresponds to a channel access method that performs channel monitoring only once.

[0100] The third type of channel access, or Type 3 channel access, corresponds to the channel access method without channel monitoring, that is, no channel monitoring is required, but the channel can be accessed directly.

[0101] In some possible implementations, determining the first configuration information among the at least two configuration information based on the at least two configuration information in step S302 includes: determining the first configuration information among the at least two configuration information based on priorities of the at least two configuration information.

[0102] In a possible example, it is determined that the configuration information with the highest priority among the at least two configuration information is the first configuration information.

[0105] In some possible implementations, the at least two pieces of configuration information include at least two of the following:

[0106] Downlink control information DCI carrying channel access mode,

[0107] RRC dedicated signaling carrying channel access mode,

[0108] Carries system information about the channel access method.

[0109] In an embodiment of the present disclosure, when a user device receives multiple configuration information carrying channel access methods, it selects one configuration information from the multiple configuration information based on the multiple configuration information, and determines that the channel access method of the user device is the channel access method carried by the selected configuration information. Therefore, when the user device receives multiple channel access methods indicated by the network device, it determines a reasonable channel access method from them, and uses this reasonable channel access method to perform channel access, thereby saving power consumption of the user device while ensuring and improving communication efficiency.

[0110] The present disclosure provides a method for determining a channel access mode, which is executed by a user equipment. Figure 4 FIG. 1 is a flow chart showing a method for determining a channel access mode according to an exemplary embodiment. Figure 4 As shown, the method includes:

[0111] Step S401: Receive at least two pieces of configuration information carrying channel access modes from a network device.

[0112] Step S402: Determine the first configuration information among the at least two configuration information based on the priorities of the at least two configuration information.

[0113] Step S403: Determine that the channel access mode of the user equipment is the channel access mode carried in the first configuration information.

[0114] In some possible implementations, determining the first configuration information among the at least two configuration information based on the priorities of the at least two configuration information in step S402 includes: determining the configuration information with the highest priority among the at least two configuration information as the first configuration information.

[0115] In some possible implementations, determining the first configuration information among the at least two configuration information based on the priorities of the at least two configuration information in step S402 includes: determining the configuration information with the second highest priority among the at least two configuration information as the first configuration information.

[0116] In some possible implementations, the channel access mode includes at least one of the following:

[0117] Type 1 channel access corresponds to a channel access method that performs N channel monitoring operations, where N is an initial value generated by the UE according to the Type 1 channel access method specification and is an integer greater than zero. The value of N can be 1 or greater.

[0118] The second type of channel access, or Type 2 channel access, corresponds to a channel access method that performs channel monitoring only once.

[0119] The third type of channel access mode, or called No-LBT, corresponds to a channel access mode without channel monitoring, that is, no channel monitoring is required, but the channel can be accessed directly.

[0120] In some possible implementations, the at least two pieces of configuration information include at least two of the following:

[0121] Downlink control information DCI carrying channel access mode,

[0122] RRC dedicated signaling carrying channel access mode,

[0123] Carries system information about the channel access method.

[0124] In some possible implementations, the above solution may further include default configuration information of the UE; the default configuration information may be the configuration information with the lowest priority, and the default configuration information is adopted only when the UE does not receive the configuration information sent by the base station.

[0125] In some possible implementations, the priority of the DCI carrying the channel access method is greater than the priority of the RRC dedicated signaling carrying the channel access method.

[0126] In one example, a user device receives two configuration information carrying a channel access method from a network device, namely a DCI carrying the channel access method and an RRC dedicated signaling, and determines that the DCI is the first configuration information, thereby determining that the channel access method carried by the DCI is the channel access method of the user device.

[0127] For example: the user equipment receives RRC dedicated signaling carrying the second channel access method (Type 2channel access) and DCI carrying the third channel access method (No-LBT) for scheduling PUSCH from the network device, determines that the DCI is the first configuration information, and determines that the third channel access method (No-LBT) carried by the DCI is the channel access method of the user equipment.

[0128] In some possible implementations, the priority of the DCI carrying the channel access method is higher than the system information carrying the channel access method.

[0129] In one example, a user device receives two configuration information carrying a channel access method from a network device, namely a DCI carrying the channel access method and a system message, and determines that the DCI is the first configuration information, thereby determining that the channel access method carried by the DCI is the channel access method of the user device.

[0130] For example: the user equipment receives a broadcast system message carrying the third channel access mode (No-LBT) and a DCI carrying the first channel access mode (Type 1 channel access) for scheduling PUSCH from the network device, determines that the DCI is the first configuration information, and determines that the first channel access mode (Type 1 channel access) carried by the DCI is the channel access mode of the user equipment.

[0131] In some possible implementations, the priority of RRC dedicated signaling carrying the channel access method is higher than the priority of system information carrying the channel access method.

[0132] In one example, a user device receives two configuration information carrying a channel access method from a network device, namely, RRC dedicated signaling carrying the channel access method and a system message, and determines that the RRC dedicated signaling is the first configuration information, thereby determining that the channel access method carried by the RRC dedicated signaling is the channel access method of the user device.

[0133] For example: the user equipment receives a system message carrying a first channel access method (Type 1 channel access) and an RRC dedicated signaling carrying a third channel access method (No-LBT) from a network device, determines that the RRC dedicated signaling is the first configuration information, and determines that the third channel access method (No-LBT) carried by the RRC dedicated signaling is the channel access method of the user equipment.

[0134] For example: the user equipment receives a system message carrying a second channel access method (Type 2 channel access) and an RRC dedicated signaling carrying a third channel access method (No-LBT) from a network device, determines that the RRC dedicated signaling is the first configuration information, and determines that the third channel access method (No-LBT) carried by the RRC dedicated signaling is the channel access method of the user equipment.

[0135] In some possible implementations, the priority of the DCI carrying the channel access method is greater than the priority of the RRC dedicated signaling carrying the channel access method, and the priority of the RRC dedicated signaling carrying the channel access method is greater than the system information carrying the channel access method.

[0136] That is, the order of priority of the three configuration information from large to small is: DCI carrying the channel access method, RRC dedicated signaling carrying the channel access method, and system information carrying the channel access method.

[0137] In one example, a user device receives three configuration information carrying a channel access method from a network device, namely, a DCI carrying the channel access method, an RRC dedicated signaling carrying the channel access method, and a system message carrying the channel access method, and determines that the DCI is the first configuration information, thereby determining that the channel access method carried by the DCI is the channel access method of the user device.

[0138] For example: the user equipment receives a DCI for scheduling PUSCH carrying a first channel access mode (Type 1channel access), an RRC dedicated signaling carrying a second channel access mode (Type 2channel access), and a system message carrying a third channel access mode (No-LBT) from a network device, determines that the DCI is the first configuration information, and determines that the first channel access mode (Type 1channel access) carried by the DCI is the channel access mode of the user equipment.

[0139] The present disclosure provides a method for determining a channel access mode, which is executed by a user equipment. Figure 5 FIG. 1 is a flow chart showing a method for determining a channel access mode according to an exemplary embodiment. Figure 5 As shown, the method includes:

[0140] Step S501: Receive at least two pieces of configuration information carrying channel access modes from a network device.

[0141] Step S502: In response to the at least two configuration information including the second configuration information, determine that the second configuration information is the first configuration information.

[0142] Step S503: Determine that the channel access mode of the user equipment is the channel access mode carried in the first configuration information.

[0143] In an embodiment of the present disclosure, second configuration information is set. When the second configuration information is included in multiple configuration information received by the user equipment, the second configuration information is used as the reference information to determine that the second configuration information is the first configuration information, and the channel access method of the user equipment is determined to be the channel access method carried by the first configuration information.

[0144] or,

[0145] like Figure 6 As shown, the method includes:

[0146] Step S601: Receive at least two pieces of configuration information carrying channel access modes from a network device.

[0147] Step S602: In response to the at least two configuration information including the second configuration information, determine that the channel access mode of the user equipment is the channel access mode carried in the second configuration information.

[0148] In an embodiment of the present disclosure, second configuration information is set. When the second configuration information is included in multiple configuration information received by the user equipment, the second configuration information is used as reference information to determine that the channel access mode of the user equipment is the channel access mode carried by the second configuration information.

[0149] In some possible implementations, the at least two pieces of configuration information include at least two of the following:

[0150] Downlink control information DCI carrying channel access mode,

[0151] RRC dedicated signaling carrying channel access mode,

[0152] Carries system information about the channel access method.

[0153] In some possible implementations, the second configuration information is preset configuration information; that is, the UE is pre-configured which configuration information is the second configuration information; after receiving at least two configuration information, the UE can determine which configuration information is the second configuration information. In other possible implementations, the second configuration information is protocol-determined configuration information; that is, the UE can determine which configuration information is the second configuration information based on the communication protocol; after receiving at least two configuration information, the UE can determine which configuration information is the second configuration information. In some possible implementations, the second configuration information has the highest priority.

[0154] In some possible implementations, the second configuration information is the configuration information with the highest priority among downlink control information (DCI) carrying the channel access method, RRC dedicated signaling carrying the channel access method, and system information carrying the channel access method. In some possible implementations, the above solution may further 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 only used when the UE does not receive configuration information sent by the base station.

[0155] In some possible implementations, the second configuration information is a DCI carrying a channel access mode. Thus, when the at least two configuration information include a DCI carrying a channel access mode, the DCI carrying the channel access mode is determined to be the first configuration information, and the channel access mode of the user equipment is determined to be the channel access mode carried by the DCI.

[0156] In some possible implementations, in response to the at least two configuration information including downlink control information DCI carrying a channel access method, the DCI is determined to be the first configuration information, and the channel access method of the user equipment is determined to be the channel access method carried by the DCI.

[0157] In some possible examples, the user equipment receives a DCI carrying a channel access method and an RRC dedicated signaling carrying a channel access method, determines that the DCI carrying the channel access method is the first configuration information, and determines that the channel access method of the user equipment is the channel access method carried by the DCI.

[0158] The present disclosure provides a method for determining a channel access mode, which is executed by a user equipment. Figure 7 FIG. 1 is a flow chart showing a method for determining a channel access mode according to an exemplary embodiment. Figure 7 As shown, the method includes:

[0159] Step S701: Receive at least two pieces of configuration information carrying channel access modes from a network device.

[0160] Step S702, in response to the at least two configuration information including third configuration information, wherein the channel access method carried by the third configuration information is different from the channel access method carried by at least one other configuration information, determine the first configuration information among the at least two configuration information based on the other configuration information among the at least two configuration information except the third configuration information.

[0161] Step S703: Determine that the channel access mode of the user equipment is the channel access mode carried in the first configuration information.

[0162] In some possible implementations, the at least two pieces of configuration information include at least two of the following:

[0163] Downlink control information DCI carrying channel access mode,

[0165] Carries system information about the channel access method.

[0166] In some possible implementations, the third configuration information is preset configuration information; that is, the UE is pre-configured to determine which configuration information is the third configuration information; after receiving at least two configuration information, the UE can determine which configuration information is the third configuration information. In other possible implementations, the third configuration information is protocol-determined configuration information; that is, the UE can determine which configuration information is the third configuration information based on the communication protocol; after receiving at least two configuration information, the UE can determine which configuration information is the third configuration information. In some possible implementations, the third configuration information is the configuration information with the lowest priority. In some possible implementations, the above scheme may also include default configuration information for the UE; this default configuration information may be the configuration information with the lowest priority and is only used if the UE does not receive configuration information sent by the base station.

[0167] In some possible implementations, the third configuration information is the configuration information with the lowest 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.

[0168] In some possible implementations, the third configuration information is system information carrying a channel access mode. Thus, when the at least two configuration information include system information carrying a channel access mode, and the channel access mode carried in the system information is different from the channel access mode carried in at least one other configuration information, the first configuration information of the at least two configuration information is determined based on the other configuration information in the at least two configuration information except the third configuration information.

[0169] In some possible examples, the user equipment receives a DCI carrying a channel access method and a system message carrying a channel access method, the channel access method carried by the DCI is different from the channel access method carried by the system message, the channel access method carried by the system message is ignored, the DCI is determined to be the first configuration information, and the channel access method of the user equipment is determined to be the channel access method carried by the DCI.

[0170] In some possible examples, the user equipment receives a DCI carrying a channel access method, an RRC dedicated signaling carrying a channel access method, and a system message carrying a channel access method. The channel access method carried by the DCI is different from the channel access method carried by the system message. The channel access method carried by the system message is ignored, the DCI or the RRC dedicated signaling is determined to be the first configuration information, and the channel access method of the user equipment is determined to be the channel access method carried by the DCI.

[0171] In an embodiment of the present disclosure, third configuration information is set. When the third configuration information is included in multiple configuration information received by the user equipment, the third configuration information is ignored, the first configuration information is determined based on other configuration information in the multiple configuration information except the third configuration information, and the channel access method of the user equipment is determined to be the channel access method carried by the first configuration information.

[0172] The present disclosure provides a method for determining a channel access mode, which is executed by a user equipment. Figure 8 FIG. 1 is a flow chart showing a method for determining a channel access mode according to an exemplary embodiment. Figure 8 As shown, the method includes:

[0174] Step S802: In response to the at least two configuration information including third configuration information, wherein the channel access mode carried by the third configuration information is different from the channel access mode carried by at least one other configuration information, ignore the third configuration information.

[0175] In some possible implementations, the at least two pieces of configuration information include at least two of the following:

[0176] Downlink control information DCI carrying channel access mode,

[0177] RRC dedicated signaling carrying channel access mode,

[0178] Carries system information about the channel access method.

[0179] In some possible implementations, the third configuration information is preset configuration information; that is, the UE is pre-configured to determine which configuration information is the third configuration information; after receiving at least two configuration information, the UE can determine which configuration information is the third configuration information. In other possible implementations, the third configuration information is protocol-determined configuration information; that is, the UE can determine which configuration information is the third configuration information based on the communication protocol; after receiving at least two configuration information, the UE can determine which configuration information is the third configuration information. In some possible implementations, the third configuration information is the configuration information with the lowest priority.

[0180] In some possible implementations, the third configuration information is the configuration information with the lowest 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.

[0181] In some possible implementations, the at least two configuration information include system information and RRC dedicated signaling. If the channel access method carried by the system information is different from the channel access method carried by the RRC dedicated signaling, the channel access method carried by the system information is ignored.

[0182] In some possible implementations, the following further comprises:

[0183] Step S803: Determine the first configuration information among the at least two configuration information based on the other configuration information among the at least two configuration information except the third configuration information.

[0184] Step S804: Determine that the channel access mode of the user equipment is the channel access mode carried in the first configuration information.

[0185] An embodiment of the present disclosure provides a method for determining a channel access mode, which is executed by a network device and includes:

[0186] At least two configuration information carrying a channel access method are sent to a user equipment; wherein the at least two configuration information include DCI, and at least one configuration information among the at least two configuration information other than the DCI carries a third type of channel access method (or called No-LBT), and the DCI carries the third type of channel access method.

[0189] It can be understood that if the network device does not configure the UE to use the No-LBT mode (including using system information to configure the UE to use the No-LBT mode, or using RRC UE dedicated signaling to configure the UE to use the No-LBT mode), the UE determines that the network device will not indicate the No-LBT mode in the DCI. That is, only when the network device is configured with the No-LBT mode can it instruct the UE to use the No-LBT mode in the DCI.
