Description

A configuration method, channel access method, network device and terminal

technical field

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

Background technique

Only the Physical Uplink Shared Channel (PUSCH) and the Sounding Reference Signal (Sounding Reference) are supported on the unlicensed frequency band in the Long Term Evolution (Long Term Evolution, referred to as LTE) licensed spectrum assisted access (LicenseAssisted Access, referred to as LAA) system Signal, SRS for short) transmission, other uplink (Uplink, UL for short) channels are not supported for transmission in unlicensed frequency bands.

The new air interface (NR in Unlicensed Spectrum, NR-U for short, New Radio, NR for short) on the unlicensed spectrum needs to be an independent unlicensed access system (ie, a standalone unlicensed system), so the physical random access channel (Physical random access channel). UL channels such as Random Access Channel (PRACH for short), PUCCH, Physical Uplink Shared Channel (PUSCH for short), and SRS all need to be transmitted on unlicensed frequency bands.

In LTE LAA, PUSCH transmission is based on the scheduling of evolved Node B (eNB for short), the eNB allocates time-frequency resources of PUSCH, and User Equipment (UE) listens before the conversation before sending. (Listen-Before-Talk, LBT for short), whether to send the PUSCH is determined through the LBT. If the LBT is successful, the PUSCH is sent, and if the LBT is not successful, the PUSCH cannot be sent. In the technical field, the LBT process is sometimes referred to as the channel access process, and the parameters related to the LBT process are sometimes referred to as the channel access process parameters.

If in NR-U, different channel resources are allocated for different UL channels according to the LTE LAA method, then when the UE performs LBT before transmission and the LBT is unsuccessful, channel resources may be wasted, making channel resources less efficient. Utilization is low.

Detailed ways

The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are part of the embodiments of the present invention, but not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

Referring to FIG. 1, FIG. 1 is a flowchart of a configuration method provided by an embodiment of the present invention, which is applied to a network device. As shown in FIG. 1, the configuration method includes the following steps:

Step 101: Simultaneously configure transmission resources to at least two uplink channels; for the transmission resources, 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 situations: 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 configured to the uplink channels of different users (in this embodiment, the users all refer to UEs) at the same time. For example, the transmission resources are configured to two PUSCHs at the same time, and the two PUSCHs belong to different users.

When the channel types of the at least two uplink channels are different, configure the same transmission resource to uplink channels belonging to different channel types at the same time, for example, configure the transmission resource to the PRACH channel and the PUSCH channel at the same time, when the transmission resource is not used by the PRACH channel , the PUSCH channel can use this transmission resource. 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 includes: Type 1 UL channel access process (ie Cat 4LBT), Type 2 UL channel access process (ie one shot LBT), automatic uplink transmission (autonomous UL transmission, AUL for short) and the like.

Transmission resources include channel resources, which can be understood as time-frequency resources.

In this embodiment, transmission resources are configured to at least two uplink channels at the same time; for the transmission resources, the at least two uplink channels correspond to different channel access procedures and/or channel access parameters. The transmission resources are allocated to at least two uplink channels at the same time, and since different uplink channels correspond to different channel access procedures and/or channel access parameters, the detection or access of these uplink channels for the same transmission resource will be different. A certain order/priority is generated. On the one hand, as long as one uplink channel successfully preempts the transmission resource, the transmission resource is used, which improves the utilization rate of the transmission resource; on the other hand, because different uplink channels correspond to different Therefore, it is generally unlikely that multiple UEs compete for channel access opportunities at the same time, and then perform UL transmission on the same time-frequency resources at the same time, thereby causing serious interference to each other's transmission. The problem is that this scheme generally does not cause collision problems. Therefore, this solution can improve the utilization rate of transmission resources on the premise of avoiding multi-UE collision.

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

Channel access priority parameters;

Start transmission position offset parameter;

The parameter of the number of attempts of the channel access process;

Listening duration parameter;

Contention window parameters.

Specifically, the channel access priority parameter can be understood as an indirect parameter, a starting transmission position offset parameter (starting offset values), a parameter of the number of attempts of the channel access process, a sensing interval parameter or a contention window parameter (contention value) window value) can be understood as a direct parameter. There is a mapping relationship between indirect parameters and direct parameters, that is, there is a mapping relationship between the channel access priority parameters and one or more parameters in the direct parameters. Through the channel access priority parameters and the mapping relationship, the connection to the channel can be determined. Enter the direct parameter corresponding to the priority parameter. The terminal attempts to access the channel on the transmission resource according to the direct parameter. Since different direct parameters are configured for different terminals and/or different uplink channels, on the one hand, a target uplink channel of a certain terminal can be prevented from colliding with the uplink channels of other terminals when it preempts transmission resources; When the terminal does not occupy the transmission resource, the terminal can still use the transmission resource, so the utilization rate of the transmission resource can be improved.

When the channel access parameter includes one or more of the start transmission position offset parameter, the number of attempts parameter of the channel access procedure, the listening duration parameter or the contention window parameter, the terminal starts transmission according to the determined parameter. One or more of the location offset parameter, the number of attempts parameter of the channel access procedure, the listening duration parameter or the contention window parameter, try to access the channel on the transmission resource.

Further, the channel access parameter includes a channel access priority parameter. 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 number of attempts parameter of the channel access process of the first uplink channel is less than the number of attempts parameter of the channel access process of the second uplink channel;

The listening duration parameter of the first upstream channel is less than the listening duration parameter of the second upstream 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 parameters include channel access priority parameters, the setting methods of the channel access priorities of different uplink channels (for the convenience of description, the channel access priorities are referred to as priorities hereinafter) are described as follows .

The priority setting methods of the uplink channel may include but are not limited to the following methods:

Mode 1: The priorities of PRACH, PUCCH, PUSCH, and SRS are sequentially decreased.

Mode 2: Subdivide the PUCCH and PUSCH carrying different signals, for example, PRACH, PUCCH (ACK/NACK), PUCCH (SR/CSI only), PUSCH (Msg3), PUSCH (Data), PUSCH (CSI only), The priorities of the SRSs decrease sequentially.

The setting of the above priority may be specified in the standard, or may be set by means of network configuration or pre-configuration.

The following describes the determination of the first starting position according to the priority, or the parameters of the LBT according to the priority sorting method of Mode 1 (the priority sorting method according to Mode 2 is the same, the difference is that the priority level in Mode 2 is higher than that in Mode 1). more), so that different UEs will not occupy transmission resources at the same time, and improve the utilization rate of transmission resources. The first start position is the start position of uplink channel transmission, and the first start position may be understood as the start transmission position offset parameter. The parameters of the LBT include one or more of the starting position of the LBT detection channel, the parameter of the number of attempts of the channel access procedure, the parameter of the listening duration and the parameter of the contention window.

The first starting position of uplink channel transmission is determined according to the priority. The higher the priority of the uplink channel, the earlier the starting position of the uplink channel transmission. The earlier the starting position of uplink channel transmission is, it can be understood that the value of the starting transmission position offset parameter is smaller.

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

L1<L2<L3<L4, L1, L2, L3, and L4 are all within the time domain of the transmission resources allocated by the base station (which can be understood as network equipment). For example, L1 is the start of the time domain of the transmission resources allocated by the base station. L2 is a certain time after L1, L3 is a certain time after L2, and L4 is a certain time after L3. In Fig. 2, "×" indicates that the preemption of the transmission resource fails, and "√" indicates that the preemption of the transmission resource succeeds.

The UE performs LBT before the sending time, so as to determine whether the signal can be sent at the sending time.

The higher the priority of the uplink channel, the earlier the first starting position, which means that the uplink channel with high priority can perform LBT detection earlier, occupy transmission resources and send data, and the LBT detection of other uplink channels with low priority If it fails, the transmission resources cannot be occupied to send data, so as to avoid conflicts caused by different uplink channels preempting the same transmission resources.

The above-mentioned method of determining the initial transmission position offset parameter sent by the uplink channel according to the priority can make the uplink channel with high priority preferentially occupy transmission resources for data transmission. The lower-level uplink channel can preempt transmission resources, reduce the waste of transmission resources, and thus improve the utilization rate of transmission resources.

Different priorities correspond to different first starting positions, and the different first starting positions 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 the case where the different first starting positions are different time domain positions in the starting symbols of the transmission resource starting slot, similar R14eLAA can be applied, and different PUSCH starting positions in 4 are set, indicated by the DCI2 bit, as shown in Table 1. Show. DCI is downlink control information (Downlink Control Information, referred to as DCI), and TA is a maximum time advance (time advanced, referred to as 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 represents the start position of symbol 0, and 11 represents the end position of symbol 0.

Set different first starting positions according to different priorities. For example, for the case where the priority is the above method 1, it is necessary to set up to 4 different first starting positions, and the four different starting positions of LTE eLAA can be reused. It can also be reset; for the case where the priority is the above-mentioned method 2, it is necessary to set up to 7 different first starting positions.

In the case where the different first starting positions are different symbol positions in the starting slot of the transmission resource, for example, four kinds of first starting positions can be set as: the starting position of symbol 0, the starting position of symbol 1, the starting position of symbol 2 The starting position and the starting position of symbol3.

When setting the first starting position, the influence of the TA of the cell also needs to be considered. Since the UE sending PRACH does not know the TA of the cell (the UE has not been uplink synchronized), therefore, the time when the UE sends may be the system time (frame timing) of the cell. The former TA (or GT value, where the GT value is the GT value in the preamble setting), or within the latter TA (or GT value). Therefore, when setting the first starting position of the uplink channels of other priorities, the difference from the starting position of the PRACH channel of the highest priority needs to be greater than one TA or GT value.

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

Among them, the priority of the uplink channel is different, and the channel detection starting position of the LBT is different. As shown in FIG. 3 , the higher the priority of the uplink channel, the higher the starting position of the LBT channel detection. The starting position of LBT channel detection can be understood as the starting transmission position offset parameter. In Fig. 3, "×" indicates that the preemption of the transmission resource fails, and "√" indicates that the preemption of the transmission resource succeeds.

According to the priority setting method of Mode 1, PRACH starts detection at time T1, PUCCH starts detection at T2 time, PUSCH starts detection at T3 time, and SRS starts detection at T4 time. T1<T2<T3<T4, T1, T2, T3, T4 are all moments before the time domain start position of the transmission resources allocated by the base station, so as to ensure that the real UL signal sent by the uplink channel is within the transmission resources allocated by the base station. Time domain start position to start sending.

If the UE detects that the transmission resource is idle, the UE occupies the transmission resource to transmit, and may first transmit the occupancy signal to occupy the channel until the UL signal is transmitted. When sending the UL signal, stop sending the occupancy signal. The occupancy signal may be a preamble signal (ie, a Premble signal), or a wake-up signal (ie, a wus signal), or a CP extension of the next valid OFDM symbol, and so on. The valid OFDM symbol refers to the first OFDM symbol in the UL signal that carries useful information. In this way, it can be ensured that the uplink channel with high priority occupies transmission resources preferentially for data transmission. If the uplink channel with high priority does not preempt transmission resources, the uplink channel with lower priority can preempt transmission resources, reduce the waste of transmission resources, and improve the efficiency of transmission. Utilization of transmission resources.

The way to determine the corresponding parameters of the LBT according to the priority can be determined in the following ways:

In the case where one shot LBT is used in the implementation of LBT, the LBT detects the same starting position of the channel, and performs M (M greater than 0) one shot LBTs. If all M one shot LBTs are idle, the channel can be occupied to send signals.

As shown in FIG. 4 , according to the different priorities of the uplink channels, the number of M is different, and the higher the priority of the uplink channel, the smaller the value of M. M can be understood as a parameter of the number of attempts of the channel access procedure. In Fig. 4, "×" indicates that the preemption of the transmission resource fails, and "√" indicates that the preemption of the transmission resource succeeds.

According to the priority setting method of method 1, PRACH performs M1 one shot LBTs, PUCCH performs M2 one shot LBTs, PUSCH performs M3 one shot LBTs, and 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 sending, and may first send the occupied signal to occupy the channel until the UL signal is sent. When sending the UL signal, stop sending the occupancy signal. In this way, it can be ensured that the uplink channel with high priority occupies transmission resources preferentially for data transmission. If the uplink channel with high priority does not preempt transmission resources, the uplink channel with lower priority can preempt transmission resources, reduce the waste of transmission resources, and improve the efficiency of transmission. Utilization of transmission resources.

In the case where one shot LBT is used in the implementation of LBT, the LBT detection channel starts at the same position, and the detection length of one shot LBT is different. The detection length of one shot LBT can be understood as the listening time.

As shown in Fig. 5, according to the priority of the uplink channel, the higher the priority of the uplink channel, the smaller the detection length of the one shot LBT. In FIG. 5 , "×" indicates that the preemption of the transmission resource fails, and "√" indicates that the preemption of the transmission resource succeeds.

According to the priority setting method of method 1, PRACH detects one shot LBT of length F1, PUCCH detects one shot LBT of length F2, PUSCH detects one shot LBT of length F3, and SRS detects one shot of length F4 shot LBT, 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 sending, and may first send the occupied signal to occupy the channel until the UL signal is sent. When sending the UL signal, stop sending the occupancy signal. In this way, it can be ensured that the uplink channel with high priority occupies transmission resources preferentially for data transmission. If the uplink channel with high priority does not preempt transmission resources, the uplink channel with lower priority can preempt transmission resources, reduce the waste of transmission resources, and improve the efficiency of transmission. Utilization of transmission resources.

In the case where the implementation of LBT adopts Cat4LBT, the window size (ie CWP) of LBT is different. The higher the priority of the uplink channel, the smaller the CWP value, and the window size can be understood as the contention window parameter. As shown in Table 2, according to the priority setting method of Mode 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, and 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 sending, and may first send the occupied signal to occupy the channel until the UL signal is sent. When sending the UL signal, stop sending the occupancy signal. In this way, it can be ensured that the uplink channel with high priority occupies transmission resources preferentially for data transmission. If the uplink channel with high priority does not preempt transmission resources, the uplink channel with lower priority can preempt transmission resources, reduce the waste of transmission resources, and improve the efficiency of transmission. Utilization of transmission resources.

When the network device configures the transmission resources to at least two uplink channels at the same time, it may adopt the mode of display indication or the mode of implicit indication.

When the network device adopts the display indication, an information element (Information Element, IE for short) or a field indicating the priority of the uplink channel may be added to the signaling for configuring or indicating the uplink channel.

For example, the PRACH may indicate the priority of the PRACH in the Radio Resource Control (RRC) (system message) that configures its resources (because the PRACH is the highest priority, it may not indicate the priority of the PRACH);

PUCCH may indicate the priority of PUCCH in DCI scheduling PDSCH, or indicate the priority of PUCCH in RRC configuring PUCCH resources;

PUSCH can indicate the priority of PUSCH in the DCI that schedules it. For semi-persistent scheduling (Semi-Persistent Scheduling, SPS) PUSCH can indicate the priority of PUSCH in the trigger DCI or in the RRC that configures its resources. For configured grant PUSCH The priority of the PUSCH can be indicated in the RRC that configures its resources;

The SRS may indicate the priority of the SRS in the RRC that configures its resources;

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

For example, if only PRACH and PUSCH are configured or indicated on the transmission resource, the indicated PRACH priority is the first priority P1, and the PUSCH priority is the second priority P2. For example, if PRACH, PUCCH, and PUSCH are configured or indicated on the transmission resource, it indicates that the PRACH priority is the first priority P1, the PUCCH priority is the second priority P2, and the PUSCH priority is the third priority P3. For example, if only PUSCH is configured or indicated on the transmission resource, the indicated PUSCH priority is the first priority P1. In this way, the UE can determine the parameters for LBT adjustment according to the configured or indicated priority.

In the case where the network device adopts the display indication, there is another implementation manner, that is, adding the sending starting position (ie the first starting position) or LBT indicating the uplink channel to the signaling for configuring or indicating the uplink channel The IE or field of the parameter (taking the start position of the LBT detection channel as an example, other methods for adjusting the LBT parameters have similar indications). The above implementation manner does not need to indicate the priority, and can directly indicate the specific adjustment parameter (the adjustment parameter here can be understood as the direct parameter described above).

For example, the PRACH may indicate the starting position of the PRACH transmission or the starting position of the LBT detection channel in the RRC (system message) that configures its resources (because the PRACH has the highest priority, it may not indicate the starting position of the PRACH);

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

PUSCH can indicate the starting position of PUSCH transmission or the starting position of LBT detection channel in the DCI that schedules it. For SPS PUSCH can indicate the starting position of PUSCH transmission or LBT detection channel in the trigger DCI or in the RRC that configures its resources. For the configured grant PUSCH, the starting position of the PUSCH transmission or the starting position of the LBT detection channel can be indicated in the RRC that configures its resources;

The SRS can indicate the starting position of the SRS transmission or the starting position of the LBT detection channel in the RRC that configures its resources;

The configured or indicated sending starting position or LBT parameter of the uplink channel refers to the sending starting position or LBT parameter in the uplink channel that is simultaneously configured or indicated on the transmission resource (following the setting of each uplink channel priority).

The following describes the starting position of the transmission of the upstream channel as an example.

For example, only PRACH and PUSCH resources are configured or indicated on the transmission resources, and the PRACH transmission start position is indicated as the first transmission start position L1, and the PUSCH transmission start position is the second transmission start position L2;

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

For example, if only the PUSCH resource is configured or indicated on the transmission resource, the indicated PUSCH transmission start position is the first transmission start position L1.

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

In the case where the network device adopts the implicit indication, the semi-static indication may be performed through a system message or UE-specific RRC signaling.

System messages or UE-specific RRC signaling use 1 bit to indicate whether the current cell supports configuring multiple uplink channels on the same transmission resource. If supported, the UE will perform LBT according to the default priority when performing LBT. Parameter adjustment (the default priority is specified in the standard at this time). If it is not supported, when performing LBT, the UE will not adjust the LBT parameters according to the priority, but use normal LBT for detection.

Implicit indications are less flexible than explicit indications, but can save signaling overhead.

When the network device adopts an implicit indication, another implementation manner is provided, that is, the UE adjusts the sending start position or LBT parameters of other uplink channels according to the position of the random access opportunity (RACH Occasion, RO for short).

The UE obtains the position of the RACH Occasion according to the system message, that is, the time-frequency resource of the PRACH preamble (preamble can be understood as a preamble signal) (which is already supported by the NR standard). If the UE finds that an uplink channel is configured on the time-frequency resource position of the RACH Occasion, the UE needs to adjust the transmission start position of the uplink channel or the LBT parameters. The specific adjustment method can be adjusted as described above. Since the PRACH channel has the highest priority, the priority of other uplink channels will be adjusted to the second priority.

The implicit indication method provided in this embodiment can only enable PRACH and other uplink channels to be multiplexed (ie, multiplexing) on the same time-frequency resource (which can be understood as a transmission resource), and cannot support multiple uplink channels other than PRACH in the same time-frequency resource (that is, multiplexing). Time-frequency resources are multiplexed, and the implicit indication method provided in this embodiment does not require any signaling overhead.

It should be noted that, if the network device adopts both the implicit indication and the explicit indication, the explicit indication may cover the implicit indication.

Further, the configuration method further includes:

For the target uplink channel, at least one uplink channel configuration message is sent, where the uplink channel configuration message carries the channel access procedure and/or channel access parameters corresponding to the target uplink channel.

The network device sends an uplink channel configuration message to the UE, and the uplink channel configuration message carries the channel access process and/or channel access parameters corresponding to the target uplink channel, so as to prevent the target uplink channel from colliding with other uplink channels when the target uplink channel preempts transmission resources. conflict, and further improve the utilization rate of transmission resources.

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

Step 201: Using the channel access process and/or channel access parameters corresponding to the target uplink channel, try to access the channel on the transmission resource, and the transmission resource is configured to at least two channels including the target uplink channel at the same time. Upstream channel.

The at least two uplink channels include two situations: 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 configured to the uplink channels belonging to different users (in this embodiment, the users all refer to UEs) at the same time.
