detailed description

The present application will be described in further detail below with reference to the accompanying drawings and embodiments.

When the 5G NR system works independently on unlicensed spectrum, the reason why stable and continuous channel resources cannot be obtained is:

The current 5G NR system configures an initial BWP for the terminal through broadcast. The terminal receives paging and system messages on the initial BWP, and initiates random access on the initial BWP. If there are more WIFI services on the initial BWP, it may result in less opportunities for the 5G NR system to obtain channel resources, which will affect the system performance. On the other hand, when in the connected state, the terminal is only allowed to be activated one BWP, and send and receive data on the activated BWP, if the WIFI interference on the activated BWP is greater, the 5G NR system may have a greater chance of acquiring channel resources Less will also have an impact on system performance.

Based on this, in various embodiments of the present application: configuring multiple initial BWPs or activating multiple BWPs, so as to enable LBT, after successful LBT, data transmission is performed, and data reception is performed on the corresponding BWP.

The solution provided in this embodiment of the present application is configured with multiple working BWPs and LBT is performed before sending data. In this way, the chance of the 5G system acquiring channel resources can be greatly increased, thereby ensuring system performance.

An embodiment of the present application provides a data transmission method, which is applied to a terminal. As shown in FIG. 1, the method includes:

Step 101: Determine multiple configured working BWPs;

Specifically, a plurality of initial BWPs configured and / or a plurality of BWPs are activated.

Here, the network configures multiple BWPs for the terminal. In other words, the network configures multiple working BWPs for the terminal.

Specifically, when the terminal is in an idle state, multiple initial BWPs are configured for the terminal; when the terminal is in a connected state, multiple BWPs are activated for the terminal.

Step 102: For multiple BWPs, perform corresponding LBT, after successful LBT, send data, and receive data on the downstream BWP.

Specifically, for multiple BWPs, the terminal may select one uplink BWP for LBT or multiple uplink BWPs for LBT; accordingly, the uplink BWP for sending data may be one or more; the data receiving There can be one downlink BWP or multiple.

Specifically, the terminal has the following implementation processes:

The first is to perform LBT on multiple upstream BWPs, send data on one upstream BWP, and receive data on one downstream BWP;

The second method is to perform LBT on multiple upstream BWPs, send data on one upstream BWP, and receive data on multiple downstream BWPs;

The third type is LBT on multiple upstream BWPs, data transmission on multiple upstream BWPs, and data reception on multiple downstream BWPs;

Fourth, LBT on multiple upstream BWPs, data transmission on multiple upstream BWPs, and data reception on one downstream BWP;

Fifth, LBT on an upstream BWP, data transmission on an upstream BWP, and data reception on a downstream BWP;

Sixth, LBT is performed on one upstream BWP, data transmission is performed on one upstream BWP, and data reception is performed on multiple downstream BWPs.

Here, in actual application, one of the above-mentioned implementation processes can be selected as needed.

In practical applications, when the terminal is in an idle state, data transmission and reception are mainly data transmission and reception during random access, such as MSG1, MSG2, MSG3, and MSG4.

When the terminal is in a connected state, the sending and receiving of data may include: sending and receiving of service data, or other data (such as scheduling information, etc.).

In practical applications, when the number of upstream BWPs for sending data and the number of downstream BWPs for receiving data are the same (for example, both are 1), there may be a certain relationship between the upstream BWP for sending data and the downstream BWP for receiving receipts.

Specifically, in a time division duplex (TDD) system, the relationship between the two may be that the uplink BWP and the downlink BWP have the same BWP index, or that the uplink BWP and the downlink BWP have different BWP indexes.

In a frequency division duplex (FDD) system, the relationship between the two may be a pairing relationship between upstream and downstream BWPs, or may be a pairing relationship that does not exist between upstream and downstream BWPs.

In practical applications, in a TDD system, the terminal may preferentially receive downlink data on a downlink BWP (which has the same BWP index as the uplink BWP) corresponding to the uplink BWP.

In the FDD system, the terminal may preferentially receive downlink data on the downlink BWP paired with the uplink BWP.

In an embodiment, LBT is performed on multiple upstream BWPs, and the sending data on one upstream BWP includes one of the following:

Send data on the BWP which was the first successful LBT;

Send data on a BWP with the highest LBT success rate;

Send data on a BWP that meets the first threshold.

Here, in actual application, the terminal may select an uplink BWP to be configured for data transmission as needed.

Among them, the LBT success rate refers to: the ratio of the number of LBT successes in a period of time to the number of LBTs in that period of time.

In an embodiment, LBT is performed on multiple upstream BWPs, and the sending data on multiple upstream BWPs includes one of the following:

Send data on multiple BWPs with successful LBT;

Send data on multiple BWPs with high LBT success rate;

Send data on multiple BWPs with a high number of LBT successes;

Send data on BWP that meets the second threshold.

In practice, the corresponding threshold requirements (such as the first threshold and the second threshold) include at least one of the following:

LBT success rate;

LBT success rate within the preset duration;

LBT success times;

The number of LBT successes within a preset duration;

LBT failure times;

The number of LBT failures within the preset duration;

LBT failure rate;

LBT failure rate within the preset duration;

RSRQ;

SINR;

RSRP.

Here, corresponding to the LBT success rate, the LBT failure rate refers to: the ratio of the number of LBT failures in a period of time to the number of LBTs in the period of time.

In actual application, the data transmission on the BWP that meets the first and second threshold requirements can be understood as: multiple BWPs determine the BWP priority, and the target BWP is determined to transmit data according to the BWP priority.

The corresponding threshold requirement may be a prescribed requirement or obtained through network distribution.

The corresponding preset duration (for example, the first preset duration, the second preset duration, the third preset duration, and the fourth preset duration) is a specified duration, or is obtained through delivery through the network.

When the terminal sends data on multiple upstream BWPs, for idle terminals, MSG1 and MSG3 can send on multiple BWPs that acquire channel resources; accordingly, when the network side also sends data on multiple downlink BWPs At this time, MSG2 may send on multiple BWPs that acquire channel resources; further, for MSG4, at this time, the network selects one BWP to send the BWP. The network selection decision can be determined by the LBT success rate and / or interference situation, etc. (can be understood as determined according to the BWP priority ranking).

Among them, MSG3 sent on multiple BWPs use the same terminal identity (or cell radio network temporary identity (C-RNTI)), so that the network knows that the received multiple random access requests come from the same terminal.

In an embodiment, when the data is sent on multiple BWPs with a high LBT success rate within the third preset duration, the method may further include:

Receive at least one of the following information delivered by the network:

LBT success rate threshold;

The number of the first BWP for data transmission;

The first maximum value of the number of BWP for data transmission.

Here, the terminal may use the above information received by the network side to further determine a plurality of BWPs with a high LBT success rate within a third preset duration to send data.

In an embodiment, when the data is sent on multiple BWPs with a high number of LBT successes within the fourth preset duration, the method may further include:

Receive at least one of the following information delivered by the network:

The threshold of the second LBT success times;

The number of the second BWP for data transmission;

The second maximum value of the number of BWP for data transmission.

Here, the terminal may use the above-mentioned information received by the network side to further determine multiple BWPs with a higher number of LBT successes within the third preset duration for data transmission.

In actual application, the terminal may acquire information of multiple uplink BWPs to perform LBT on the multiple uplink BWPs.

Based on this, in an embodiment, acquiring information of multiple upstream BWPs of LBT includes at least one of the following:

The specified number of upstream BWP for LBT;

The specified maximum number of upstream BWPs for LBT;

Number of upstream BWPs issued by the network for LBT;

The maximum number of upstream BWPs delivered by the network for LBT.

In actual application, the terminal may report the uplink BWP information of LBT, so that the network device can learn, and then can receive the sent data in time.

Based on this, in an embodiment, the method may further include:

Wherein, the content of the first signaling includes at least one of the following:

LBT on a BWP;

LBT on multiple BWP;

The number of BWP that carried out LBT;

The maximum number of BWPs that perform LBT.

In practical applications, the first signaling may be radio resource control (RRC) signaling or the like.

In actual application, the network may also deliver downlink BWP information to the terminal, so that the terminal can learn, and thus can receive data sent by the network in time.

Based on this, in an embodiment, the method may further include:

Here, the second signaling may be RRC signaling, broadcasting (such as a physical broadcast channel (PBCH), etc.), system messages, and so on.

The content of the second signaling includes at least one of the following:

Receive data on a downstream BWP;

Not receiving data on a downstream BWP;

Receive data on multiple downstream BWPs;

Not receiving data on multiple downstream BWPs;

Number of BWP receiving downstream data;

BWP index for receiving downstream data.

In the working process of each BWP, a timer or counter can be introduced. If there is no data transmission (upstream BWP) or data reception (downstream BWP) within the duration of the timer or the value of the counter, BWP switching is performed, for example, it can be prioritized according to BWP Perform BWP switching in order of level.

Here, the duration of the timer or counter can be configured by the network side, such as system messages (for the terminal in the idle state), RRC messages (for the terminal in the connected state), and so on.

No data reception within the timer duration or counter value (downstream BWP) can be understood as: no uplink data scheduling, and / or downlink data scheduling, and / or downlink data scheduling, and / or are received within the timer duration or counter value Or receive downstream data, etc.

Among them, in actual application, during the operation of the timer or counter, it can be determined whether a synchronization signal / physical broadcast channel block (SSB) is received, and / or other reference symbols to determine whether network scheduling or downlink data is not received. Because the base station does not acquire downlink channel resources. If the terminal receives SSB and / or other reference symbols, the BWP-converted timer recounts or the counter recounts.

Here, for the connected terminal, RRC signaling can also be used to notify the terminal whether it is scheduled, so as to help the terminal distinguish whether the network scheduling information is not received within a certain period of time because the network does not schedule the terminal or the network fails to obtain the downlink channel Resources. If the terminal receives the RRC signaling, the timer converted by the BWP recounts or the counter recounts.

In practice, in order to be able to send data in time, when there is no LBT success within a certain period of time on the corresponding BWP, a BWP conversion is required.

Based on this, in an embodiment, when LBT is performed on the BWP, the method may further include one of the following:

Among them, in actual application, a timer or a counter can be set, and within the timer duration or the value of the counter without LBT success, BWP switching is performed.

The corresponding preset duration (for example, the fifth preset duration, the sixth preset duration, and the seventh preset duration) may be a specified duration, or may be acquired through network delivery.

The third threshold may be a prescribed threshold for the number of failed LBTs, or a threshold for the number of failed LBTs delivered by the network.

The fourth threshold may be a specified LBT failure rate threshold or a LBT failure rate threshold delivered by the network.

The fifth threshold may be a prescribed LBT success rate threshold, or may be a LBT success rate threshold delivered by the network.

When performing BWP conversion, the terminal also needs to determine the target BWP for BWP conversion. Among them, the target BWP for BWP conversion can be determined according to one of the following ways:

Independently determine the target BWP;

Take BWP that meets certain threshold requirements as the target BWP;

Here, the autonomous determination of the target BWP means that the terminal neither uses the BWP that meets certain threshold requirements as the target BWP nor uses the index of the target BWP issued by the network to determine the target BWP, but determines it in other ways. For example, if you randomly select a BWP as the target BWP, you can also sort multiple BWPs yourself, and select a BWP as the target BWP in order, and so on.

In practical applications, the threshold requirement may include at least one of the following:

LBT success rate;

LBT success rate within a specific duration;

LBT success times;

The number of LBT successes within a specific duration;

LBT failure times;

The number of LBT failures within a specific duration;

LBT failure rate;

LBT failure rate within a specific time period;

RSRQ;

SINR;

RSRP.

Wherein, the specific duration can be determined as needed.

Here, the BWP that meets certain threshold requirements is regarded as the target BWP, which can be understood as: multiple BWPs determine the BWP priority, and the target BWP is determined according to the BWP priority.

In practical applications, the terminal may also report the BWP information for data transmission, that is, the ability to report the uplink BWP supported by itself for data transmission, so that the network side can accurately receive the data, and can also indicate the data based on the terminal's How does the terminal send data on the upstream BWP.

Based on this, in an embodiment, the method may further include:

The content of the third signaling includes at least one of the following:

Support data transmission on an upstream BWP;

Support data transmission on multiple upstream BWP;

Does not support data transmission on multiple upstream BWP;

The number of multiple upstream BWPs for data transmission;

The maximum number of multiple upstream BWPs for data transmission;

Upstream BWP index for data transmission.

In practical applications, the third signaling may be RRC signaling or the like.

In an embodiment, the method may further include:

Wherein, the content of the fourth signaling includes at least one of the following:

Number of upstream BWP for data transmission;

The maximum number of upstream BWPs for data transmission;

Upstream BWP index for data transmission.

Here, in actual application, the fourth signaling may be RRC signaling or the like.

Correspondingly, the embodiments of the present application also provide a data transmission method, which is applied to a network device, as shown in FIG. 2, the method includes:

Step 201: Configure multiple working BWPs for the terminal;

Specifically, multiple initial BWPs are configured for the terminal and / or multiple BWPs are activated.

Here, the network device may be a base station, and in a 5G system, the base station is a next-generation Node B (gNB).

Step 202: For multiple BWPs, perform corresponding LBT, after successful LBT, send data, and receive data on the upstream BWP.

Specifically, for multiple BWPs, the network device may select one uplink BWP for LBT or multiple uplink BWPs for LBT; accordingly, the uplink BWP for sending data may be one or more; receive data The downlink BWP can be one or multiple.

Specifically, the network device has the following implementation processes:

The first is to perform LBT on multiple downstream BWPs, send data on one downstream BWP, and receive data on one upstream BWP;

The second method is to perform LBT on multiple downstream BWPs, send data on multiple downstream BWPs, and receive data on one upstream BWP;

The third type is LBT on multiple downlink BWPs, data transmission on multiple downlink BWPs, and data reception on multiple uplink BWPs;

Fourth, LBT on multiple downstream BWPs, data transmission on one downstream BWP, and data reception on multiple upstream BWPs;

Fifth, LBT is performed on a downstream BWP, data is transmitted on a downstream BWP, and data is received on an upstream BWP;

Sixth, LBT is performed on one downstream BWP, data transmission is performed on multiple downstream BWPs, and data reception is performed on one upstream BWP.

In actual application, when the terminal is in idle state, data transmission and reception are mainly data transmission and reception during random access, such as MSG1, MSG2, MSG3, and MSG4.

In practical applications, when the number of downlink BWPs of transmitted data and the number of uplink BWPs of received data are the same (for example, both are 1), there may be a certain relationship between the downlink BWP of transmitted data and the uplink BWP of the received receipt.

Specifically, in the TDD system, the relationship between the two may be that the uplink BWP and the downlink BWP have the same BWP index, or that the uplink BWP and the downlink BWP have different BWP indexes.

In the FDD system, there may be a pairing relationship between upstream and downstream BWP, or there may be no pairing relationship between upstream and downstream BWP.

In practical applications, in a TDD system, the network device may preferentially receive uplink data on an uplink BWP corresponding to a downlink BWP (which has the same BWP index as the downlink BWP).

In the FDD system, the network device may preferentially receive uplink data on the uplink BWP paired with the downlink BWP.

In an embodiment, LBT is performed on multiple downlink BWPs, and the downlink data transmission on one downlink BWP includes one of the following:

Send data on the BWP which was the first successful LBT;

Send data on a BWP with the highest LBT success rate;

Send data on a BWP that meets the sixth threshold.

Here, in actual application, the network device may select a downlink BWP to be configured for data transmission as needed.

In an embodiment, LBT is performed on multiple downlink BWPs, and the downlink data transmission on multiple downlink BWPs includes one of the following:

Send data on multiple BWPs with successful LBT;

Send data on multiple BWPs with high LBT success rate;

LBT success rate;

LBT success rate within the preset duration;

LBT success times;

The number of LBT successes within a preset duration;

LBT failure times;

The number of LBT failures within the preset duration;

LBT failure rate;

LBT failure rate within the preset duration;

RSRQ;

SINR;

RSRP.

In actual application, the data transmission on the BWP that meets the sixth and seventh threshold requirements can be understood as: multiple BWPs determine the BWP priority, and the target BWP is determined to transmit data according to the BWP priority.

When the network device sends data on multiple downlink BWPs, for the terminal in idle state, MSG2 can send on multiple BWPs that acquire channel resources; for MSG4, the network side selects one BWP to send the BWP at this time. The network selection decision can be determined by the LBT success rate and / or interference situation, etc. (can be understood as determined according to the BWP priority ranking).

In actual applications, the network device may deliver some information to the terminal to enable the terminal to perform data transmission, such as LBT on the corresponding BWP, selection of upstream BWP to send data, selection of BWP to perform LBT, etc. Wait.

Based on this, in an embodiment, the method may further include:

Number of upstream BWP;

In practical applications, the terminal may report its own uplink BWP information for LBT, so that the network device can learn, and thus can receive the sent data in time.

Based on this, in an embodiment, the method may further include:

In actual application, the network device may also deliver downlink BWP information to the terminal, so that the terminal can learn, and thus can receive data sent by the network device in time.

Based on this, in an embodiment, the method may further include:

Here, the second signaling may be RRC signaling, broadcast (PBCH), system message, or the like.

The content of the second signaling includes at least one of the following:

Receive data on a downstream BWP;

Not receiving data on a downstream BWP;

Receive data on multiple downstream BWPs;

Not receiving data on multiple downstream BWPs;

Number of BWP receiving downstream data;

BWP index for receiving downstream data.

During the working process of each BWP, a timer or counter can be introduced. If there is no data transmission (downstream BWP) or data reception (upstream BWP) within the duration of the timer or the value of the counter, BWP switching is performed, for example, it can be prioritized according to BWP Perform BWP switching in order of level.

Here, when sending the downlink data, the corresponding SSB and / or other reference symbols may be sent to the terminal, so that the terminal judges whether the network scheduling or the downlink data is not received because the base station has not obtained the downlink channel resource. If the terminal receives SSB and / or other reference symbols, the BWP converted timer recounts or the counter recounts.

Here, for the connected terminal, RRC signaling can also be used to notify the terminal whether it is scheduled, so as to help the terminal distinguish whether the network scheduling information is not received within a certain period of time because the network does not schedule the terminal or the network fails to obtain the downlink channel Resources. If the terminal receives the RRC signaling, the timer converted by BWP is recounted or the counter is recounted.

When performing BWP conversion, the network device also needs to determine the target BWP for BWP conversion. Among them, the target BWP for BWP conversion can be determined according to one of the following ways:

Independently determine the target BWP;

Target BWP that meets certain threshold requirements.

Here, the autonomous determination of the target BWP means that the network device does not use the BWP that meets certain threshold requirements as the target BWP, but determines it in other ways, such as randomly selecting a BWP as the target BWP, or by itself multiple The BWP is sorted, and a BWP is selected as the target BWP in order and so on.

RSRP.

Wherein, the specific duration can be determined as needed.

In practical applications, the terminal can also report BWP information for data transmission, that is, the ability to report the uplink BWP supported by itself for data transmission, so that the network device can accurately receive data, and can also instruct the terminal based on the capabilities of the terminal How does the terminal send data on the upstream BWP.

Here, it should be noted that step 301 and step 302 have no order in execution.

In addition, the specific processing procedures of the terminal and the network device have been described in detail above, and will not be repeated here.

Since multiple working BWPs are configured and LBT is performed before data is sent, this can greatly increase the chance of the 5G system acquiring channel resources, thereby ensuring system performance.

The application will be described in further detail below in conjunction with application examples.

Application Example 1

In this application example, the terminal is in an idle state, and the network configures the terminal with three initial downlink BWPs, namely BWP-1, BWP-2, and BWP-3; meanwhile, the working priority of the three BWPs is BWP-1 > BWP-2> BWP-3, that is, BWP-1 has the highest priority, BWP-2 has the second priority, and BWP-3 has the lowest priority. In addition, the network also configures timers for the terminals. The timers corresponding to BWP-1 and BWP-2 are timer1 and timer2, respectively.

The terminal first works on BWP-1 and starts timer1. If timer1 expires, the terminal does not receive SIB1 and / or MSG2 or MSG4 with random access at BWP-1, then the terminal switches to BWP-2 and starts timer2 If timer2 expires and the terminal does not receive SIB1 at BWP-2, then the terminal switches to BWP-3 to work.

Application Example 2

In this application example, the terminal is in an idle state, and the network configures the terminal with three initial upstream BWPs, namely BWP-1, BWP-2, and BWP-3; meanwhile, the working priority of the three BWPs is BWP-1 > BWP-2> BWP-3, that is, BWP-1 has the highest priority, BWP-2 has the second priority, and BWP-3 has the lowest priority. In addition, the network also configures counters for the terminals. The timers corresponding to BWP-1 and BWP-2 are counter1 and counter2, respectively.

The terminal works on BWP-1 first, turn on counter1, if counter1 expires, the terminal does not get the channel to send MSG1 or MSG3 in BWP-1, then the terminal switches to BWP-2, turns on counter2, if counter2 expires, the terminal is in BWP- 2 There is no acquisition channel to send MSG1 or MSG3, then the terminal switches to BWP-3 to work.

Application Example 3

In this application example, the terminal is in a connected state, and the network configures the terminal with four downlink BWPs, namely BWP-1, BWP-2, BWP-3, and BWP-4; the working priority of the four BWPs is BWP- 1> BWP-2> BWP-3> BWP-4, that is, BWP-1 has the highest priority, BWP-2 has the second priority, BWP-3 has the third priority, and BWP-4 has the lowest priority. In addition, the network also configures timers for the terminals. The timers corresponding to BWP-1, BWP-2, and BWP-3 are timer1, timer2, and timer3, respectively.

The terminal first works on BWP-1, and turns on timer1. If timer1 expires, the terminal does not receive SSB and / or other reference symbols in BWP-1 and / or does not receive RRC signaling and / or notification that the terminal is scheduled If no downlink scheduling is received and / or no downlink data is received, then the terminal switches to BWP-2 and starts timer2. If timer2 expires, the terminal does not receive SSB and / or other reference symbols and / or does not receive in BWP-2 To inform the terminal whether RRC signaling is scheduled and / or has not received downlink scheduling and / or has not received downlink data, the terminal switches to BWP-3 and starts timer3. If timer3 expires, the terminal does not receive BWP-3. When the SSB and / or other reference symbols are received and / or RRC signaling notifying whether the terminal is scheduled and / or downlink scheduling and / or downlink data is not received, the terminal switches to BWP-4 to work.

Application Example 4

In this application example, the terminal is in a connected state, and the network configures the terminal with four upstream BWPs, namely BWP-1, BWP-2, BWP-3, and BWP-4; the working priority of the four BWPs is BWP- 1> BWP-2> BWP-3> BWP-4, that is, BWP-1 has the highest priority, BWP-2 has the second priority, BWP-3 has the third priority, and BWP-4 has the lowest priority. In addition, the network also configures timers for the terminals. The timers corresponding to BWP-1, BWP-2, and BWP-3 are timer1, timer2, and timer3, respectively.

The terminal first works on BWP-1, and turns on timer1. If timer1 expires, the terminal does not acquire channel resources in BWP-1 and cannot send uplink data. Then the terminal switches to BWP-2 and turns on timer2. If timer2 expires, the terminal If the channel data cannot be sent without acquiring channel resources in BWP-2, the terminal switches to BWP-3, and timer 3 is turned on. If timer 3 expires, the terminal does not acquire channel resources in BWP-3 and cannot send uplink data. Then the terminal switches Work at BWP-4.

As can be seen from the above description, multiple BWPs have work priority, and BWP conversion timers and counters are introduced. After the timer or counter expires, the terminal automatically switches to the BWP work of the second priority according to the BWP priority. The terminal receives system messages and pages according to the priority configuration, completes random access, and sends and receives uplink and downlink data.
