Before describing the embodiments of the present invention in detail, a brief description of unlicensed spectrum and NR system will be given.
For the unlicensed spectrum, the LTE system supports Carrier Aggregation (CA) to use the unlicensed spectrum. In specific implementation, a Primary Cell (PCell) operates on a licensed spectrum to provide a basic access function and a data transmission function; a Secondary Cell (SCell) operates on unlicensed spectrum and is used as a data boosting function. However, in the LTE system Licensed Assisted Access (LAA) operation mode, the RACH is on the PCell, and thus the RACH function is not optimized for the unlicensed spectrum. In the LAA protocol in the related art, PUCCH is also not supported on the unlicensed spectrum, i.e., SR is transmitted on the licensed spectrum.
The NR system supports LAA using unlicensed spectrum and also supports stand-alone using unlicensed spectrum.
In the NR system, an SR is transmitted by a terminal device to a network device (e.g., a gNB) to inform the terminal device of a need to transmit data to the network device. In the NR system, the terminal device may support at most 8 SR configurations (configurations), each logical channel may correspond to at most one SR configuration, the logical channel may not correspond to an SR configuration, and the network device may determine the type of the logical channel that triggers current SR transmission through different SR configurations.
When the NR system uses the unlicensed spectrum by using the LAA, the LAA defines two access types, i.e., type1 and type 2. For type1, the terminal device may select different channel access priorities according to the service types, and the correspondence between the channel access priorities and quality of service Class indicators (QCIs) is shown in table 1. For type2, the terminal needs to fix the time for listening for 25us before transmitting the Physical Uplink Shared Channel (PUSCH).
Channel Access Priority Class(p) | QCI |

2 | 2,7 |

TABLE 1
An optional processing flow one of the method for determining a channel access type applied to a terminal device, as shown in fig. 2, includes the following steps:
step S101, a terminal device determines a first channel access type of a physical uplink control channel for sending a scheduling request based on a logical channel triggering the scheduling request.
In the embodiment of the invention, when data on a logical channel meets the triggering condition of a Buffer Status Report (BSR), the BSR is triggered; further, when the trigger condition of the SR is satisfied, the SR is triggered.
Here, the channel access types may have different priorities, and the different priorities reflect the duration of the channel to be finally listened to.
For example, the channel access types are divided based on the channel monitoring duration to obtain a first channel access type, a second channel access type, an nth channel access type; each channel access type corresponds to a channel monitoring duration; the higher the channel access priority, the higher the probability of selecting the length of time for monitoring the channel. It can be understood that, from the statistical point of view, the probability that the channel access type with the higher channel access priority selects the duration of the monitored channel is higher than the probability that the channel access type with the lower channel access priority selects the duration of the monitored channel.
In some embodiments, the logical channel has configuration parameters, and the configuration parameters of the logical channel include at least one channel access type; the terminal equipment determines a first channel access type of a PUCCH used for transmitting the SR based on the configuration parameters of the logical channel.
In other embodiments, the terminal device determines, based on the ID of the logical channel, a configuration parameter of the SR corresponding to the logical channel in a mapping relationship between the logical channel and the configuration parameter of the SR; the configuration parameters of the SR comprise at least one channel access type; and the terminal equipment determines a first channel access type of a PUCCH used for transmitting the SR in the at least one channel access type.
In a specific implementation, the terminal device may determine a first channel access type of a PUCCH used for transmitting the SR based on a configuration parameter of the logical channel or based on a ranking of at least one channel access type included in the configuration parameter of the SR; for example, the first channel access type is determined as the first channel access type, or the last channel access type is determined as the first channel access type. The terminal device may also sort the channel monitoring durations corresponding to at least one channel access type included in the configuration parameters of the logical channel or the configuration parameters of the SR, and determine the channel access type corresponding to the shortest channel monitoring duration as the first channel access type. The terminal device may also sort the window sizes corresponding to at least one channel access type included in the configuration parameters of the logical channel or the configuration parameters of the SR, and determine the channel access type corresponding to the largest window size as the first channel access type.

step S102, when the configuration parameters of the logical channel and the configuration parameters of the scheduling request do not contain the channel access type, the terminal device determines the pre-configured channel access type as the second channel access type of the physical uplink control channel for sending the scheduling request.
In this embodiment of the present invention, the preconfigured channel access type may be a channel access type broadcasted by the network device in a broadcast manner, or a channel access type sent by the network device to the terminal device in a signaling manner.
An optional processing flow iii of the method for determining a channel access type provided in the embodiment of the present invention is similar to the optional processing flow i, except that after step S101, the method further includes:
step S103, when the configuration parameters of the logical channel and the configuration parameters of the scheduling request do not contain the channel access type, the terminal device determines the second channel access type of the physical uplink control channel for sending the scheduling request based on the parameters of the service carried by the logical channel.
In the embodiment of the present invention, the service parameters at least include: latency, reliability, or required data rate.
In some embodiments, when the parameter of the service is a time delay and the time delay is smaller than a preset first threshold, a first channel access type with a high priority is adopted.
An optional process flow four of the method for determining a channel access type provided in the embodiment of the present invention is similar to the optional process flow one described above, except that after step S101, the method further includes:
step S104, when the terminal equipment fails to acquire the physical uplink control channel based on the first channel access type, determining a second channel access type of the physical uplink control channel for sending the scheduling request based on the sequencing of at least one channel access type in the configuration parameters of the logical channel.
In some embodiments, at least one channel access type in the configuration parameters of the logical channels is sorted in descending order according to the number of times the channel access type history is selected, and the channel access type sorted before is determined as the second channel access type.
In other embodiments, the channel access types are sorted according to their priority order, and the channel access type sorted before is determined as the second channel access type; here, the channel access types to be ranked may include the first channel access type, or may not include the first channel access type.
An optional processing flow five of the method for determining a channel access type provided in the embodiment of the present invention is similar to the optional processing flow one described above, except that after step S101, the method further includes:
step S105, when the terminal device fails to acquire the physical uplink control channel based on the first channel access type, randomly selecting one channel type from a channel type list configured by a logical channel as a second channel access type of the physical uplink control channel for sending the scheduling request.
It should be noted that, in the foregoing embodiment of the present invention, the second channel access type is a channel access type of a PUCCH resource available next to transmit the SR.
The channel access priority of the first channel access type is higher than the channel access priority of the second channel access type.
An optional processing flow sixteenth and fifteenth of the method for determining a channel access type provided in the embodiment of the present invention is similar to the optional processing flow first described above, except that after step S101, the method further includes:
and step S106, the terminal equipment monitors the PUCCH based on the first channel access type.
And S107, when the monitoring result indicates that the PUCCH is available, transmitting the SR on the PUCCH.
In the above embodiments of the present invention, the terminal device determines the first channel access type based on the logical channel, and performs SR transmission based on the PUCCH resource on the unlicensed spectrum based on the determined first access type.
An optional processing flow one of the method for determining a channel access type applied to a network device, as shown in fig. 3, includes the following steps:
step S201, the network device configures configuration parameters of a logical channel and/or configuration parameters of a scheduling request for the terminal device.
In the embodiment of the invention, the configuration parameters of the logical channel and the SR are used for the terminal equipment to determine the channel access type of the PUCCH for sending the SR; wherein,
the configuration parameters of the logical channel and the configuration parameters of the SR at least comprise one channel access type.
As shown in fig. 4, the optional processing flow of the method for determining a channel access type, which is provided in the embodiment of the present invention and applied to a communication system, includes the following steps:
step S301, the network device configures configuration parameters of the logical channel and/or configuration parameters of the scheduling request for the terminal device.
Here, the configuration parameters of the logical channel and the configuration parameters of the SR each include at least one channel access type.
Step S302, the terminal device determines a first channel access type of a PUCCH used for transmitting the SR based on the logical channel triggering the SR.
In some embodiments, the terminal device determines the first channel access type based on at least one channel access type included in configuration parameters of a logical channel of the SR.
In other embodiments, the terminal device determines a configuration parameter of an SR corresponding to the logical channel based on the ID of the logical channel, and determines the first channel access type based on at least one channel access type included in the configuration parameter of the SR.
In still other embodiments, when the network device configures the configuration parameters of the logical channel and the configuration parameters of the SR for the terminal device at the same time, and the configuration parameters of the logical channel and the configuration parameters of the SR both include at least one channel access type, the terminal device selects the configuration parameters based on the logical channel or the configuration parameters based on the SR according to a preset policy to determine the first channel access type.
Step S303, when the terminal device fails to determine the first channel access type, or fails to acquire the physical uplink control channel based on the first channel access type, determines the second channel access type.
In the above embodiments of the present invention, the channel access priority of the first channel access type is higher than the channel access priority of the second channel access type. In some embodiments, the channel access priority comprises at least a first channel access priority and a second channel access priority; the first channel access priority is the highest level of channel access priority, and if the channel interception time length is fixed to 25 us; the second channel access priority is configurable channel access priority, such as channel monitoring duration and window size configured according to the configurable channel access priority.
