Description

Configuration method, channel access method, network equipment and terminal

Technical Field

The present invention relates to the field of communications technologies, and in particular, to a configuration method, a channel access method, a network device, and a terminal.

Background

In a Long Term Evolution (LTE) authorized spectrum Assisted Access (LAA) system, only Physical Uplink Shared Channel (PUSCH) and Sounding Reference Signal (SRS) are supported for transmission in an unlicensed frequency band, and other Uplink (UL) channels are not supported for transmission in the unlicensed frequency band.

In a New air interface (NR in Unlicensed Spectrum, NR-U for short, New Radio, NR for short) on an Unlicensed Spectrum, since an independent Unlicensed Access system (i.e., a persistent Unlicensed system) needs to be provided, UL channels such as a Physical Random Access Channel (PRACH for short), a PUCCH, a Physical Uplink Shared Channel (PUSCH for short), an SRS, and the like need to be transmitted on an Unlicensed frequency band.

In LTE LAA, PUSCH transmission is scheduled based on an evolved Node B (eNB), the eNB allocates time-frequency resources of PUSCH, and a User Equipment (User Equipment, UE for short) performs Listen-Before-Talk (Listen-Before-Talk, LBT for short) Before sending, and determines whether to send PUSCH through LBT. If LBT is successful, PUSCH is transmitted, and if LBT is not successful, PUSCH cannot be transmitted. In the art, LBT procedures are sometimes also referred to as channel access procedures, and LBT procedure related parameters are sometimes also referred to as channel access procedure parameters.

If different channel resources are allocated to different UL channels in the NR-U according to the LTE LAA manner, when the UE performs LBT before transmission and LBT is unsuccessful, the channel resources may be wasted, so that the utilization rate of the channel resources is low.

Detailed Description

The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are some, not all, embodiments of the present invention. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.

Referring to fig. 1, fig. 1 is a flowchart of a configuration method provided in an embodiment of the present invention, and is applied to a network device, as shown in fig. 1, the configuration method includes the following steps:

step 101, configuring transmission resources to at least two uplink channels simultaneously; for the transmission resource, the at least two uplink channels correspond to different channel access procedures and/or channel access parameters.

The at least two uplink channels include two cases: the at least two uplink channels belong to different users, or the channel types of the at least two uplink channels are different.

Specifically, when the at least two uplink channels belong to different users, the same transmission resource is simultaneously configured to the uplink channels of the different users (in this embodiment, the users are all referred to as UEs). For example, transmission resources are simultaneously configured to two PUSCHs, which belong to different users.

When the channel types of the at least two uplink channels are different, the same transmission resource is simultaneously configured to the uplink channels belonging to different channel types, for example, the transmission resource is simultaneously configured to the PRACH channel and the PUSCH channel, and when the transmission resource is not used by the PRACH channel, the transmission resource can be used by the PUSCH channel. The uplink channels belonging to different channel types may belong to the same user or may belong to different users, which is not limited herein.

The channel access process comprises the following steps: a Type 1UL channel access procedure (i.e., Cat 4LBT), a Type 2UL channel access procedure (i.e., one shot LBT), an automatic uplink transmission (AUL for short), and the like.

The transmission resources include channel resources, which may be understood as time-frequency resources.

In this embodiment, transmission resources are simultaneously configured to at least two uplink channels; for the transmission resource, the at least two uplink channels correspond to different channel access procedures and/or channel access parameters. The transmission resources are simultaneously configured to at least two uplink channels, and different uplink channels correspond to different channel access processes and/or channel access parameters, so that the uplink channels can generate a certain sequence/priority for the detection or access of the same transmission resource; on the other hand, because different uplink channels correspond to different channel access procedures and/or channel access parameters, a problem that multiple UEs simultaneously compete for channel access opportunities, and then UL transmission is simultaneously performed on the same time-frequency resource, and further severe interference is caused to transmission of each other generally does not occur, that is, the scheme generally does not cause a collision problem. Therefore, the scheme can improve the utilization rate of transmission resources on the premise of avoiding the collision of multiple UEs.

Further, the channel access parameter includes at least one of the following parameters:

a channel access priority parameter;

an initial transmission position offset parameter;

the parameter of the number of times of trying the channel access process;

monitoring a time length parameter;

a contention window parameter.

Specifically, the channel access priority parameter may be an indirect parameter, and the starting transmission position offset parameter (starting offset values), the number of attempts of the channel access procedure parameter, the sensing interval parameter (sensing interval) or the contention window parameter (contention window value) may be a direct parameter. The indirect parameters and the direct parameters have a mapping relation, that is, the channel access priority parameters and one or more of the direct parameters have a mapping relation, and the direct parameters corresponding to the channel access priority parameters can be determined through the channel access priority parameters and the mapping relation. And the terminal tries to access the channel on the transmission resource according to the direct parameters. Different direct parameters are configured for different terminals and/or different uplink channels, so that on one hand, the conflict between a certain target uplink channel of a certain terminal and the uplink channels of other terminals when transmission resources are seized can be avoided; on the other hand, when other terminals do not occupy the transmission resource, the terminal can use the transmission resource, so that the utilization rate of the transmission resource can be improved.

And under the condition that the channel access parameters comprise one or more of initial transmission position offset parameters, attempt times parameters of a channel access process, interception time length parameters or competition window parameters, the terminal attempts to access the channel on the transmission resources according to one or more of the determined initial transmission position offset parameters, the determined attempt times parameters of the channel access process, the interception time length parameters or the competition window parameters.

Further, the channel access parameter includes a channel access priority parameter, and if the channel access priority parameter of the first uplink channel is greater than the channel access priority of the second uplink channel, at least one of the following relationships is satisfied:

the initial transmission position offset parameter of the first uplink channel is smaller than the initial transmission position offset parameter of the second uplink channel;

the parameter of the number of times of trying the channel access process of the first uplink channel is smaller than the parameter of the number of times of trying the channel access process of the second uplink channel;

the interception duration parameter of the first uplink channel is less than the interception duration parameter of the second uplink channel;

the contention window parameter of the first uplink channel is smaller than the contention window parameter of the second uplink channel.

In the case where the channel access parameter includes a channel access priority parameter, a manner of setting channel access priorities (hereinafter, the channel access priorities are simply referred to as priorities for convenience of description) for different uplink channels is explained as follows.

The priority setting mode of the uplink channel may include, but is not limited to, the following modes:

mode 1: the priority of PRACH, PUCCH, PUSCH and SRS is reduced in sequence.

Mode 2: the PUCCH and PUSCH carrying different signals are subdivided, and for example, the priority of PRACH, PUCCH (ACK/NACK), PUCCH (SR/CSI only), PUSCH (Msg3), PUSCH (data), PUSCH (CSI only), and SRs is sequentially lowered.

The setting of the priority may be specified in a standard, or may be performed in a network configuration or a pre-configuration manner.

The following describes determining the first starting position or the parameter of LBT according to the priority ranking mode of mode 1 (the priority ranking mode according to mode 2 is the same, and the difference is that the priority level in mode 2 is higher than that in mode 1), so that different UEs do not occupy the transmission resource at the same time, and the utilization rate of the transmission resource is improved. The first starting position is a starting position of uplink channel transmission, and the first starting position can be understood as a starting transmission position offset parameter. The parameters of LBT include one or more of a starting position of LBT detection channel, a number of attempts parameter of channel access procedure, a listening duration parameter, and a contention window parameter.

And determining a first starting position of uplink channel transmission according to the priority. The higher the priority of the uplink channel, the earlier the start position of the uplink channel transmission. The earlier the starting position of the uplink channel transmission is understood to be the smaller the value of the starting transmission position offset parameter.

As shown in fig. 2, the PRACH starts transmission at time L1, the PUCCH starts transmission at time L2, the PUSCH starts transmission at time L3, and the SRS starts transmission at time L4.

L1< L2< L3< L4, L1, L2, L3, and L4 are all within the time domain range of the transmission resource allocated by the base station (which may be understood as network devices), for example, L1 is the start position of the time domain of the transmission resource allocated by the base station, L2 is a time after L1, L3 is a time after L2, and L4 is a time after L3. In fig. 2, "×" indicates a failure of preemption of the transmission resource, and "√" indicates a success of preemption of the transmission resource.

The UE performs LBT before the transmission time to determine whether the transmission time can transmit a signal.

The higher the priority of the uplink channel is, the earlier the first starting position is, which means that the uplink channel with the higher priority can perform LBT detection earlier to occupy transmission resources and send data, and the LBT detection of the other uplink channels with the lower priority fails to occupy the transmission resources and send data, so as to avoid the collision caused by different uplink channels occupying the same transmission resources.

The manner for determining the initial transmission position offset parameter sent by the uplink channel according to the priority can enable the uplink channel with high priority to preferentially occupy the transmission resource for data transmission, and if the uplink channel with high priority does not occupy the transmission resource, the uplink channel with low priority can occupy the transmission resource, thereby reducing the waste of the transmission resource and improving the utilization rate of the transmission resource.

The different priorities correspond to different first starting positions, which may be: different time domain positions in the starting symbol of the starting slot of the transmission resource, or different symbol positions in the starting slot of the transmission resource.

In case the different first starting positions are different time domain positions in the starting symbol of the starting slot of the transmission resource, similar to R14eLAA, different PUSCH starting positions in 4 may be set, indicated by DCI2 bits, as shown in table 1. DCI is Downlink Control Information (DCI), and TA is Time Advanced (TA).

TABLE 1

Value	PUSCH starting position
		00	symbol 0
01	25μs in symbol 0
		10	(25+TA)μs in symbol 0
11	symbol 1

In table 1, 00 denotes the starting position of symbol 0, and 11 denotes the ending position of symbol 0.

Different first starting positions are set according to different priorities, for example, for the case of the priority in the above mode 1, at most 4 different first starting positions need to be set, and four different starting positions of the LTE eLAA can be reused or reset; in the case of the priority level of the above-described mode 2, it is necessary to set up a maximum of 7 different first start positions.

In the case that the different first starting positions are different symbol positions in the starting slot of the transmission resource, for example, 4 kinds of first starting positions may be set as: the starting position of symbol 0, the starting position of symbol 1, the starting position of symbol 2 and the starting position of symbol 3.

When the first starting location is set, the influence of the cell TA needs to be considered, and since the UE transmitting the PRACH does not know the TA of the cell (the UE does not have uplink synchronization yet), the time of UE transmission may be in the TA (or GT value, where the GT value is the GT value in the preamble setting) before the system time (frame timing) of the cell or in the TA (or GT value) after the system time (frame timing) of the cell. Therefore, when setting the first starting position, the uplink channels of other priorities need to differ from the starting position of the PRACH channel of the highest priority by more than one TA or GT value.

Determining parameters of the LBT according to the priority, comprising: determining the initial position of LBT for channel detection; or determining the corresponding parameters of the LBT according to different LBT modes.

The priority of the uplink channel is different, and the initial position of the LBT channel detection is different. As shown in fig. 3, the higher the priority of the uplink channel, the earlier the LBT channel detection start position. The starting position of LBT channel detection may be understood as a starting transmission position offset parameter. In fig. 3, "×" indicates a failure of preemption of the transmission resource, and "√" indicates a success of preemption of the transmission resource.

According to the priority setting method of the method 1, the PRACH starts to detect at the time T1, the PUCCH starts to detect at the time T2, the PUSCH starts to detect at the time T3, and the SRS starts to detect at the time T4. T1< T2< T3< T4, T1, T2, T3, and T4 are all time points before the time domain starting position of the transmission resource allocated by the base station, so that it is guaranteed that the actual UL signal transmitted by the uplink channel starts to be transmitted at the time domain starting position of the transmission resource allocated by the base station.

If the UE detects that the transmission resource is idle, the UE occupies the transmission resource for transmission, and may first transmit an occupied channel until transmitting the UL signal. And stopping transmitting the occupancy signal when the UL signal is transmitted. The occupancy signal may be a preamble signal (i.e., a preamble signal), or a wake-up signal (i.e., an wus signal), or a CP extension of the next valid OFDM symbol, etc. Wherein, the effective OFDM symbol refers to the first OFDM symbol carrying useful information in the UL signal. Therefore, the uplink channel with high priority can be guaranteed to preferentially occupy the transmission resources for data transmission, and if the uplink channel with high priority does not occupy the transmission resources, the uplink channel with low priority can occupy the transmission resources, so that the waste of the transmission resources is reduced, and the utilization rate of the transmission resources is improved.

The method for determining the corresponding parameter of LBT according to the priority can be determined as follows:

under the condition that one shot LBT is adopted in the LBT implementation mode, starting positions of LBT detection channels are the same, M (M is larger than 0) one shot LBTs are carried out, and the channels can be occupied to send signals if the M one shot LBTs are all idle.

As shown in fig. 4, the number of M is different according to the priority of the uplink channel, and the higher the priority of the uplink channel, the smaller the value of M. M may be understood as a number of attempts parameter for a channel access procedure. In fig. 4, "×" indicates a failure of preemption of the transmission resource, and "√" indicates a success of preemption of the transmission resource.

According to the priority setting mode of the mode 1, the PRACH performs M1 one-shot LBTs, the PUCCH performs M2 one-shot LBTs, the PUSCH performs M3 one-shot LBTs, the SRS performs M4 one-shot LBTs, M1< M2< M3< M4(M1 is greater than 0). If the UE detects that the transmission resource is idle, the UE occupies the transmission resource for transmission, and may first transmit an occupied channel until transmitting the UL signal. And stopping transmitting the occupancy signal when the UL signal is transmitted. Therefore, the uplink channel with high priority can be guaranteed to preferentially occupy the transmission resources for data transmission, and if the uplink channel with high priority does not occupy the transmission resources, the uplink channel with low priority can occupy the transmission resources, so that the waste of the transmission resources is reduced, and the utilization rate of the transmission resources is improved.

Under the condition that one shot LBT is adopted in the implementation manner of LBT, the starting positions of LBT detection channels are the same, and the detection lengths of the one shot LBT are different. The detection length of one shot LBT can be understood as the listening duration.

As shown in fig. 5, according to different priorities of the uplink channels, the higher the priority of the uplink channel is, the smaller the detection length of one shot LBT is. In fig. 5, "×" indicates a failure of preemption of the transmission resource, and "√" indicates a success of preemption of the transmission resource.

According to the priority setting mode of the mode 1, the PRACH detects one shot LBT with a length of F1, the PUCCH detects one shot LBT with a length of F2, the PUSCH detects one shot LBT with a length of F3, and the SRS detects one shot LBT with a length of F4, where F1< F2< F3< F4(F1 is greater than 0). If the UE detects that the transmission resource is idle, the UE occupies the transmission resource for transmission, and may first transmit an occupied channel until transmitting the UL signal. And stopping transmitting the occupancy signal when the UL signal is transmitted. Therefore, the uplink channel with high priority can be guaranteed to preferentially occupy the transmission resources for data transmission, and if the uplink channel with high priority does not occupy the transmission resources, the uplink channel with low priority can occupy the transmission resources, so that the waste of the transmission resources is reduced, and the utilization rate of the transmission resources is improved.

In the case where an implementation of LBT employs Cat4LBT, the window size of LBT (i.e., CWP) is different. The higher the priority of the uplink channel is, the smaller the value of the CWP is, and the window size can be understood as a contention window parameter. As shown in table 2, according to the priority setting manner of manner 1, the LBT window size of PRACH is W1, the LBT window size of PUCCH is W2, the LBT window size of PUSCH is W3, the LBT window size of SRS is W4, W1< W2< W3< W4(W1 is greater than 0).

TABLE 2

If the UE detects that the transmission resource is idle, the UE occupies the transmission resource for transmission, and may first transmit an occupied channel until transmitting an UL signal. And stopping transmitting the occupancy signal when the UL signal is transmitted. Therefore, the uplink channel with high priority can be guaranteed to preferentially occupy the transmission resources for data transmission, and if the uplink channel with high priority does not occupy the transmission resources, the uplink channel with low priority can occupy the transmission resources, so that the waste of the transmission resources is reduced, and the utilization rate of the transmission resources is improved.

When the network device configures the transmission resources to at least two uplink channels simultaneously, the network device may adopt a display indication mode or an implicit indication mode.

In the case that the network device adopts the display indication, an Information Element (IE) or a field indicating the priority of the uplink channel may be added to a signaling configuring or indicating the uplink channel.

For example, the PRACH may indicate a priority of the PRACH in a Radio Resource Control (RRC) message (system message) configuring resources thereof (since the PRACH is a highest priority, the priority of the PRACH may not be indicated);

the PUCCH may indicate the priority of the PUCCH in DCI that schedules the PDSCH or in RRC that configures PUCCH resources;

the PUSCH may indicate the priority of the PUSCH in DCI Scheduling the PUSCH, may indicate the priority of the PUSCH in trigger DCI or RRC configuring resources of Semi-Persistent Scheduling (SPS for short) and may indicate the priority of the PUSCH in RRC configuring resources of configured grant PUSCH;

the SRS may indicate its priority in the RRC configuring its resources;

the configured or indicated priority refers to that the priority in the uplink channel is configured or indicated on the transmission resource at the same time (following the setting of each uplink channel priority).

For example, only PRACH and PUSCH are configured or indicated on the transmission resources, the PRACH priority is indicated as a first priority P1, and the PUSCH priority is indicated as a second priority P2. For example, the PRACH, PUCCH, and PUSCH are configured or indicated on the transmission resource, and the PRACH priority is indicated as a first priority P1, the PUCCH priority is indicated as a second priority P2, and the PUSCH priority is indicated as a third priority P3. For example, only PUSCH is configured or indicated on the transmission resource, the PUSCH priority is indicated as the first priority P1. In this way, the UE may determine the parameters for LBT adjustment based on the configured or indicated priority.

In the case that the network device adopts the display indication, there is another implementation manner, that is, an IE or a field indicating a transmission start position (i.e., a first start position) or an LBT parameter (taking the start position of the LBT detection channel as an example, the indication manner of other methods for adjusting the LBT parameter is similar) of the uplink channel is added in the signaling configuring or indicating the uplink channel. The above implementation need not indicate priority, but directly indicate specific tuning parameters (the tuning parameters herein are understood to be the direct parameters described above).

For example, the PRACH may indicate a transmission start position of the PRACH or a start position of an LBT detection channel in an RRC (system message) configuring its resources (the start position of the PRACH may not be indicated because the PRACH is the highest priority);

the PUCCH may indicate a transmission start position of the PUCCH or a start position of the LBT detection channel in DCI scheduling the PDSCH, or indicate a transmission start position of the PUCCH or a start position of the LBT detection channel in RRC configuring PUCCH resources;

the PUSCH may indicate a transmission start position of the PUSCH or a start position of the LBT detection channel in DCI where it is scheduled, may indicate a transmission start position of the PUSCH or a start position of the LBT detection channel in trigger DCI or RRC where its resources are configured for SPS PUSCH, and may indicate a transmission start position of the PUSCH or a start position of the LBT detection channel in RRC where its resources are configured for configured grant PUSCH;

the SRS may indicate a transmission start position of the SRS or a start position of an LBT detection channel in the RRC configuring its resources;

the configured or indicated transmission start position or LBT parameter of the uplink channel refers to a transmission start position or LBT parameter (following the setting of the priority of each uplink channel) in the uplink channel configured or indicated on the transmission resource at the same time.

The following description will be made by taking the transmission start position of the uplink channel as an example.

For example, only PRACH is configured or indicated on the transmission resource, and the PUSCH resource indicates that the PRACH transmission starting position is the first transmission starting position L1, and the PUSCH transmission starting position is the second transmission starting position L2;

for example, if PRACH, PUCCH, and PUSCH are configured or indicated on the transmission resource, it is indicated that the PRACH transmission start position is a first transmission start position L1, the PUCCH transmission start position is a second transmission start position L2, and the PUSCH transmission start position is a third transmission start position L3;

for example, only PUSCH resources are configured or indicated on the transmission resources, the PUSCH transmission starting position is indicated as the first transmission starting position L1.

The sizes of L1, L2 and L3 are shown in fig. 2.

In the case where the network device is using implicit indication, the indication may be semi-static via system messages or UE-specific RRC signaling.

The system message or UE-specific RRC signaling uses 1-bit indication, whether the current cell supports configuring multiple uplink channels on the same transmission resource, and if so, the UE performs LBT parameter adjustment according to the default priority order (where the default priority is specified in the standard) when performing LBT. If not, the UE does not adjust the LBT parameters according to the priority but detects with normal LBT when performing LBT.

Implicit indication is not flexible with explicit indication, but signaling overhead can be saved.

Under the condition that the network device adopts the implicit indication, another implementation manner is also provided, that is, the UE adjusts the transmission start positions or LBT parameters of other uplink channels according to the position of a random access opportunity (RACH occupancy, abbreviated as RO).

The UE obtains the location of RACH occupancy, i.e. the time-frequency resource (supported by NR standard) of PRACH preamble (preamble can be understood as preamble). If the UE finds that the uplink channel is configured in the time-frequency resource location of the RACH Occasion, the UE needs to adjust the transmission start location or the LBT parameter of the uplink channel, and the specific adjustment manner may be adjusted according to the foregoing manner. Since the PRACH channel has the highest priority, the priority of the other uplink channels is adjusted to the second priority.

The implicit indication method provided in this embodiment only enables multiplexing (i.e., multiplexing) of the PRACH and other uplink channels on the same time-frequency resource (which may be understood as a transmission resource), and cannot support multiplexing of a plurality of uplink channels other than the PRACH on the same time-frequency resource.

It should be noted that if the network device adopts the implicit indication and the explicit indication at the same time, the explicit indication may override the implicit indication.

Further, the configuration method further comprises:

and sending at least one uplink channel configuration message aiming at a target uplink channel, wherein the uplink channel configuration message carries a channel access flow and/or a channel access parameter corresponding to the target uplink channel.

The network equipment sends an uplink channel configuration message to the UE, wherein the uplink channel configuration message carries a channel access flow and/or a channel access parameter corresponding to the target uplink channel, so that the target uplink channel is prevented from colliding with other uplink channels when the target uplink channel occupies transmission resources, and the utilization rate of the transmission resources is further improved.

Referring to fig. 6, fig. 6 is a flowchart of a channel access method provided in an embodiment of the present invention, which is applied to a terminal, and as shown in fig. 6, the channel access method includes the following steps:

step 201, attempting to access a channel on the transmission resource by using a channel access procedure and/or a channel access parameter corresponding to the target uplink channel, where the transmission resource is configured to at least two uplink channels including the target uplink channel at the same time.

Specifically, when the at least two uplink channels belong to different users, the same transmission resource is configured to the uplink channels belonging to different users (in this embodiment, the users are all referred to as UEs) at the same time. For example, transmission resources are simultaneously configured to two PUSCHs, which belong to different users.

When the channel types of the at least two uplink channels are different, the same transmission resource is simultaneously configured to the uplink channels belonging to different channel types, for example, the transmission resource is simultaneously configured to the PRACH and the PUSCH, and when the transmission resource is not used by the PRACH, the transmission resource can be used by the PUSCH. The uplink channels belonging to different channel types may belong to the same user or may belong to different users, which is not limited herein.

In this embodiment, a channel access procedure and/or a channel access parameter corresponding to a target uplink channel are used to attempt to access a channel on the transmission resource, where the transmission resource is simultaneously configured to at least two uplink channels including the target uplink channel. The transmission resources are simultaneously configured to at least two uplink channels including the target uplink channel, and as long as one uplink channel successfully preempts the transmission resources, the transmission resources are utilized, so that the utilization rate of the transmission resources is improved.

Further, in step 201, before the attempting to access the channel on the transmission resource by using the channel access procedure and/or the channel access parameter corresponding to the target uplink channel, the method further includes:

and receiving an uplink channel configuration message for configuring the target uplink channel, wherein the uplink channel configuration message is used for indicating a channel access process and/or a channel access parameter corresponding to the target uplink channel.

And a terminal (the terminal can also be understood as UE) receives an uplink channel configuration message sent by the network equipment, wherein the uplink channel configuration message is used for indicating a channel access flow and/or a channel access parameter corresponding to the target uplink channel, so that the target uplink channel is prevented from colliding with other uplink channels when the target uplink channel occupies the transmission resources, and the utilization rate of the transmission resources is further improved.

a channel access priority parameter;

an initial transmission position offset parameter;

the parameter of the number of times of trying the channel access process;

monitoring a time length parameter;

a contention window parameter.

Specifically, the channel access priority parameter may be an indirect parameter, and the starting transmission position offset parameter (starting offset values), the number of attempts of the channel access procedure parameter, the sensing interval parameter (sensing interval) or the contention window parameter (contention window value) may be a direct parameter. The indirect parameters and the direct parameters have a mapping relation, that is, the channel access priority parameters and one or more of the direct parameters have a mapping relation, and the direct parameters corresponding to the channel access priority parameters can be determined through the channel access priority parameters and the mapping relation. And the terminal tries to access the channel on the transmission resource according to the direct parameters, so that the conflict between the target uplink channel and other uplink channels when the target uplink channel occupies the transmission resource is avoided, and the utilization rate of the transmission resource is improved.

The relevant contents of the channel access priority parameter, the initial transmission position offset parameter, the number of attempts of the channel access procedure parameter, the listening duration parameter, and the contention window parameter may also refer to the relevant records in the above configuration method embodiments, which are not described herein again.

Further, when the channel access parameter includes a channel access priority parameter, attempting to access the channel on the transmission resource by using a channel access procedure and/or a channel access parameter corresponding to the target uplink channel specifically includes:

determining at least one of an initial transmission position offset parameter, an attempt time parameter of a channel access process, an interception duration parameter and a contention window parameter corresponding to the target uplink channel according to the channel access priority parameter;

attempting access to a channel on the transmission resource using the determined parameter.

Specifically, the terminal pre-acquires an indirect parameter and a direct parameter having a mapping relationship therebetween, that is, a mapping relationship exists between a channel access priority parameter and one or more of the direct parameters (that is, an initial transmission position offset parameter, a channel access procedure attempt time parameter, an interception duration parameter, and a contention window parameter), and the direct parameter corresponding to the channel access priority parameter can be determined by the channel access priority parameter and the mapping relationship. The terminal tries to access the channel on the transmission resource by using the determined parameter (namely the determined direct parameter), thereby avoiding the conflict between the target uplink channel and other uplink channels when the target uplink channel occupies the transmission resource and improving the utilization rate of the transmission resource.

Further, in step 201, after attempting to access the channel on the transmission resource by using the channel access procedure and/or the channel access parameter corresponding to the target uplink channel, the method further includes:

and sending an occupancy signal to occupy the transmission resource under the condition that the transmission resource is determined to be idle.

Specifically, the occupancy signal may be a preamble signal (i.e., a preamble signal) or a wake-up signal (i.e., an wus signal), and the terminal sends the occupancy signal to occupy the transmission resource when determining that the transmission resource is idle, so as to avoid the transmission resource being occupied by other uplink channels and improve the utilization rate of the transmission resource.

Referring to fig. 7, fig. 7 is a flowchart of a channel access method provided in an embodiment of the present invention, which is applied to a terminal, and as shown in fig. 7, the channel access method provided in this embodiment includes the following steps:

step 301, determining a transmission resource corresponding to a target uplink channel;

step 302, if the physical random access channel PRACH is not configured on the transmission resource, attempting to access a channel on the transmission resource according to a first type channel access procedure and/or a first type channel access parameter; and/or the presence of a gas in the atmosphere,

and if the transmission resource is configured with a physical random access channel PRACH, trying to access a channel on the transmission resource according to a second type channel access flow and/or a second type channel access parameter.

Specifically, the first type channel access procedure, the first type channel access parameter, the second type channel access procedure, and the second type channel access parameter may all be determined by protocol pre-provisioning, high-level signaling, or downlink control signaling (DCI).

The channel access process comprises the following steps: a Type 1UL channel access procedure (i.e., Cat 4LBT), a Type 2UL channel access procedure (i.e., one shot LBT), an automatic uplink transmission (AUL for short), and the like. The transmission resources comprise channel resources, which may be understood as time-frequency resources.

The target uplink channel is at least one of a Physical Uplink Control Channel (PUCCH), a Physical Uplink Shared Channel (PUSCH), an uplink channel determined according to a Downlink Control Information (DCI), and an uplink channel corresponding to an automatic uplink transmission (AUL).

The UE can obtain the location of RACH occupancy according to the system message, that is, the time-frequency resource (supported by NR standard) of PRACH preamble (preamble can be understood as preamble). If the UE finds that the uplink channel is configured in the time-frequency resource location of the RACH Occasion, the UE needs to adjust the transmission start location or the LBT parameter of the uplink channel, and the specific adjustment manner may be adjusted according to the foregoing manner. Since the PRACH channel has the highest priority, the priorities of the other uplink channels are adjusted to the second priority.

The embodiment can lead the PRACH and other uplink channels to be multiplexed on the same time frequency resource (which can be understood as transmission resource), thereby improving the utilization rate of the transmission resource.

In the embodiment, transmission resources corresponding to a target uplink channel are determined; under the condition that the transmission resource is configured with a Physical Random Access Channel (PRACH), adjusting a channel access flow and/or a channel access parameter of the target uplink channel; and trying to access the channel on the transmission resource by using the adjusted channel access flow and/or channel access parameters corresponding to the target uplink channel. The PRACH and other uplink channels can be multiplexed on the same transmission resource, and as long as one uplink channel successfully preempts the transmission resource, the transmission resource is utilized, so that the utilization rate of the transmission resource is improved.

Further, before the determining the transmission resource corresponding to the target uplink channel, the method further includes:

and receiving a high-level signaling, and trying to access a channel on the transmission resource according to a second type channel access flow and/or a second type channel access parameter if the PRACH is configured on the transmission resource.

In one embodiment, the higher layer signaling is a boolean variable. If the high-level signaling is set to true, determining that if the transmission resource is configured with a Physical Random Access Channel (PRACH), trying to access a channel on the transmission resource according to a second type channel access flow and/or a second type channel access parameter; and if the high-layer signaling is set to false, determining that the channel is tried to be accessed on the transmission resource only according to the first-type channel access flow and/or the first-type channel access parameters under any condition.

In another embodiment, the higher layer signaling is an optional configuration parameter. If the high-level signaling is configured, determining that if a Physical Random Access Channel (PRACH) is configured on the transmission resource, trying to access a channel on the transmission resource according to a second type channel access flow and/or a second type channel access parameter; and if the higher layer signaling is not configured, determining to try to access the channel on the transmission resource only according to the first type channel access flow and/or the first type channel access parameters under any condition.

Further, the first type of channel access parameter and/or the second type of channel access parameter includes at least one of the following parameters:

a channel access priority parameter;

an initial transmission position offset parameter;

the parameter of the number of times of trying the channel access process;

monitoring a time length parameter;

And under the condition that the channel access parameters comprise one or more of initial transmission position offset parameters, attempt times parameters of a channel access process, interception time length parameters or competition window parameters, the terminal attempts to access the channel on the transmission resources according to one or more of the determined initial transmission position offset parameters, attempt times parameters of the channel access process, interception time length parameters or competition window parameters.
