Description

Technical Field

[0001] This disclosure relates to the field of wireless communication technology, and in particular to a method, apparatus and readable storage medium for determining a channel access mode. Background Technology

[0002] In wireless communication technologies, such as 5G, on unlicensed spectrum, the transmitting end typically needs to listen to the channel before occupying it to send data; this is known as clear channel assessment (CCA). After performing CCA, if the transmitting end determines that the channel is idle, it can occupy the channel to transmit and receive data. The maximum channel occupy time (MCOT) is determined by the protocol or configured / indicated by the base station. If the channel is determined to be occupied, it cannot be occupied. This process is generally referred to as the listen-before-talk (LBT) channel access mechanism on unlicensed spectrum. LBT can also be categorized into different types based on specific channel access parameters.

[0003] On unlicensed spectrum, LBT-free channel access can also be used, meaning that the transmitter can directly occupy the channel without needing to perform channel listening.

[0004] The Downlink Control Information (DCI) can have an information field indicating the channel access method for uplink transmission by the terminal. However, existing protocols only contain channel access method information, considering only the case where one DCI schedules one Physical Uplink Shared Channel (PUSCH). When the user equipment supports one DCI scheduling more than one uplink channel, it is necessary to consider how to determine the channel access method for these multiple PUSCHs.

[0153] In one possible implementation, the second type of channel access, or Type 2 channel access, corresponds to a channel access method that performs channel listening only once.

[0154] In one possible implementation, a transmission burst may include more than one uplink channel if the interval between two uplink channels is less than 16 microseconds, in which case the two uplink channels can be divided into the same transmission burst.

These more than one PUSCHs may be continuous or discontinuous in the time domain, or some of these more than one PUSCHs may be continuous in the time domain and some may be discontinuous in the time domain.

[0161] In one possible implementation, it further includes: sending a transmission burst corresponding to the second type of channel access method, and performing channel listening only when sending the first uplink channel included in the transmission burst.

[0162] In this embodiment of the disclosure, the second type of channel access method used in DCI to indicate an application scenario where one DCI schedules one uplink channel is used to determine that the first uplink channel access method in each transmission burst in an application scenario where one DCI schedules multiple uplink channels is the second type of channel access method. This makes the information of an application scenario where one DCI schedules one uplink channel applicable to the information of an application scenario where one DCI schedules one uplink channel, thereby improving the data processing capability of the user equipment.

These more than one PUSCHs may be continuous or discontinuous in the time domain, or some of these more than one PUSCHs may be continuous in the time domain and some may be discontinuous in the time domain.

[0175] In one possible implementation, step S801 further includes: determining that the channel access mode of the other transmission bursts in one or more uplink channels of the DCI scheduling, excluding the first transmission burst, is the second type of channel access mode.

[0176] In one possible implementation, step S801 further includes: when the interval between the start time of the latter transmission burst and the end time of the former transmission burst in any two adjacent transmission bursts in one or more uplink channels scheduled by the DCI is less than or equal to a set value, determining that the channel access method of the latter transmission burst is the same as the channel access method of the former transmission burst.

[0177] In one possible implementation, step S801 further includes: when the interval between the start time of the latter transmission burst and the end time of the former transmission burst in any two adjacent transmission bursts in one or more uplink channels scheduled by the DCI is greater than a set value, determining that the channel access mode of the latter transmission burst is a first type of channel access mode.

This makes the information of an application scenario where one DCI schedules one uplink channel applicable to the information of an application scenario where one DCI schedules one uplink channel, thereby improving the data processing capability of the user equipment.

[0180] This disclosure provides a method for determining a channel access mode, which is executed by a user equipment or a network device. Figure 9 This is a flowchart illustrating a method for determining a channel access mode according to an exemplary embodiment, such as... Figure 9 As shown, the method includes:

[0181] Step S901: In response to a channel access mode information indication of a second type of channel access mode in the DCI, determine the channel access mode of the other transmission bursts in one or more uplink channels scheduled by the DCI, excluding the first transmission burst, as the second type of channel access mode;

[0182] The second type of channel access method is a channel access method that performs channel listening only once.

[0183] In one possible implementation, the second type of channel access, or Type 2 channel access, corresponds to a channel access method that performs channel listening only once.

[0184] This disclosure provides a method for determining a channel access method, which is executed by a user equipment or a network device. The method includes:

[0185] In response to a channel access mode information indication of a second type of channel access mode in the DCI, when the interval between the start time of the latter transmission burst and the end time of the former transmission burst in any two adjacent transmission bursts in one or more uplink channels scheduled by the DCI is less than or equal to a set value, it is determined that the channel access mode of the latter transmission burst is the same as the channel access mode of the former transmission burst.

[0186] and / or;

[0187] In response to a channel access mode information indication of a second type of channel access mode in the DCI, when the interval between the start time of the latter transmission burst and the end time of the former transmission burst in any two adjacent transmission bursts in one or more uplink channels scheduled by the DCI is greater than a set value, the channel access mode of the latter transmission burst is determined to be the first type of channel access mode.

[0188] The second type of channel access method is a channel access method that performs channel monitoring only once.

[0189] The first type of channel access method is a channel access method that performs N channel listening operations, where N is an initial value generated by the user equipment according to the first type of channel access method specification, and N is an integer greater than zero.

[0190] This disclosure can be applied to situations where the first transmission burst in one or more uplink channels scheduled by DCI uses the default channel access method. In one possible implementation, the default type is the second type channel access method.

[0191] This disclosure provides a method for determining a channel access mode, which is executed by a user equipment or a network device. Figure 10 This is a flowchart illustrating a method for determining a channel access mode according to an exemplary embodiment, such as... Figure 10 As shown, the method includes:

[0192] Step S1001: In response to a channel access mode information indication of a second type of channel access mode in the DCI, determine the channel access mode of the other transmission bursts in one or more uplink channels scheduled by the DCI, excluding the first transmission burst, as the first type of channel access mode.

[0193] In one possible implementation, the second type of channel access, or Type 2 channel access, corresponds to a channel access method that performs channel listening only once.

[0194] In one possible implementation, the first type of channel access, or Type 1 channel access, corresponds to a channel access method that performs N channel sniffings, where N is an initial value generated by the UE according to the Type 1 channel access specification, and N is an integer greater than zero. The value of N can be 1 or a value greater than 1.

[0195] Given that Type 2 channel access is generally used in scenarios where the UE shares the gNB's COT, it requires that the interval between the end time of the gNB's most recent downlink transmission and the start time of the UE's transmission be less than a certain gap Y. If the gNB adopts a shared COT approach, using one DCI to schedule multiple PUSCHs, and the interval between the start time of the first PUSCH transmission and the end time of the base station's downlink transmission is less than gap Y, then the first transmission burst can apply Type 2 channel access as instructed by the gNB. However, for subsequent transmission bursts, it becomes difficult for the base station to ensure that the interval between the end time of the most recent downlink transmission and the time when the UE begins transmitting this transmission burst is less than gap Y. Therefore, it is determined that Type 1 channel access will be used for the second and subsequent transmission bursts.

[0196] Based on the same concept as the above method embodiments, this disclosure also provides a communication device that can have the functions of the user equipment 102 in the above method embodiments and is used to execute the steps performed by the user equipment 102 provided in the above embodiments.

[0199] In one possible implementation, the uplink channel is one of the following:

[0200] Physical Uplink Shared Channel (PUSCH);

[0201] Physical Uplink Control Channel (PUCCH);

[0202] Sounding Reference Signal (SRS) channel.

[0203] In one possible implementation, the uplink channel is PUSCH.

[0204] In one possible implementation, the channel access method includes:

[0205] Type 1 channel access corresponds to a channel access method that performs N channel sniffings, where N is an initial value generated by the UE according to the Type 1 channel access specification, and N is a positive integer. The value of N can be 1 or a value greater than 1. In one example, this initial value is random.

[0206] The second type of channel access, also known as Type 2 channel access, corresponds to the channel access method that performs channel listening only once.

[0207] The third type of channel access, also known as Type 3 channel access, corresponds to the channel access method without channel monitoring, meaning that channel monitoring is not required, but channel access can be performed directly.

[0208] In one possible implementation, a channel access mode information in the DCI is used to indicate the channel access mode of an uplink channel when a DCI schedules an uplink channel.

[0209] In one possible implementation, when a DCI schedules more than one PUSCH, a DCI can schedule a maximum of 8 PUSCHs. These more than one PUSCHs may be continuous or discontinuous in the time domain, or some of these more than one PUSCHs may be continuous in the time domain and some may be discontinuous in the time domain.

[0257] Based on the same concept as the above method embodiments, this disclosure also provides a communication device that can have the functions of the network device 101 in the above method embodiments and is used to execute the steps performed by the network device 101 provided in the above embodiments. This function can be implemented by hardware, or by software, or by hardware executing corresponding software.

[0259] like Figure 11 The communication device 1100 shown includes a processing module 1102 for performing the steps performed by the network device 101 in the above method embodiments.

[0260] Alternatively, the processing module 1102 is used to determine the channel access method of one or more uplink channels scheduled by DCI according to the protocol.

[0261] In one possible implementation, the transceiver module 1102 sends a transmission burst corresponding to the first type of channel access method, and performs channel listening only when sending the first uplink channel included in the transmission burst. When the communication device is a network device, its structure can also be as follows: Figure 13 As shown. Taking network device 101 as a base station as an example, the structure of the communication device is explained. Figure 13 As shown, the device 1300 includes a memory 1301, a processor 1302, a transceiver component 1303, and a power supply component 1306.

The processor 1302 is configured to support the communication device 1300 in performing the corresponding functions described above; this function can be implemented by calling the programs stored in the memory 1301. The transceiver component 1303 can be a wireless transceiver, used to support the communication device 1300 in receiving signaling and / or data, and transmitting signaling and / or data via a wireless air interface.

[0262] When the communication device 1300 needs to send data, the processor 1302 performs baseband processing on the data to be sent and outputs a baseband signal to the radio frequency (RF) unit. The RF unit then performs RF processing on the baseband signal and transmits the RF signal as electromagnetic waves through an antenna. When data is sent to the communication device 1300, the RF unit receives the RF signal through the antenna, converts the RF signal into a baseband signal, and outputs the baseband signal to the processor 1302. The processor 1302 converts the baseband signal back into data and processes the data.
