Description

Resource allocation method, uplink transmission method, terminal equipment and network equipment

Technical Field

The present invention relates to the field of communications technologies, and in particular, to a resource allocation method, an uplink transmission method, a terminal device, and a network device.

Background

In future communication systems, an Unlicensed Band (Unlicensed Band) may be used as a supplement to a Licensed Band (Licensed Band) to help an operator to expand the capacity of services. Since the unlicensed band is shared by multiple Radio Access Technologies (RATs), such as Wi-Fi, radar, LTE-LAA, etc., in some countries or regions, the unlicensed band must be used according to regulatory regulations to ensure that all devices can fairly share the resources, such as Listen Before Talk (LBT), Maximum Channel Occupancy Time (MCOT), etc. When a transmission node needs to send information, it is required to perform LBT on a specified wireless channel first, and perform Energy Detection (ED) on the surrounding wireless transmission environment, and when the Energy is lower than a certain threshold, the channel is judged to be idle, and then transmission can be started. Otherwise, the channel is judged to be busy, and the transmitting node cannot transmit. The transmission node may be a base station, a User Equipment (UE), a Wi-Fi Access Point (AP), or the like. After the transmission node starts transmission, the occupied channel time cannot exceed the MCOT.

At present, when an unlicensed frequency band is utilized, if a terminal device in a certain cell performs actual uplink Transmission in multiple consecutive Transmission Time Intervals (TTIs) within a Channel Occupancy Time (COT) and continuously occupies a Channel during Transmission, the terminal device in an adjacent cell may continuously detect strong interference when performing LBT listening, which may cause LBT listening failure, thereby blocking uplink Transmission of the terminal device in the adjacent cell starting at a certain Time point within the several consecutive TTIs, thereby reducing Channel utilization efficiency.

Hereinafter, a resource allocation method and an uplink transmission method according to an embodiment of the present invention will be described with reference to the drawings.

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

step 101: configuration information is obtained.

The configuration information includes first resource configuration information of a current serving cell, the first resource configuration information includes first indication information, the first indication information is used for indicating at least one first reserved time interval of the current serving cell, and the first reserved time interval is used for a terminal device of an adjacent cell to perform LBT listening.

Note that, the content indicated by the first indication information may include: the number of first reserved time intervals, the position and length of each first reserved time interval, and the like. In a communication system using an unlicensed frequency band, the first reserved time interval belongs to a certain COT acquired by LBT from a current serving cell, and the location configuration of a single first reserved time interval may be in the form of a system time domain granularity index, where the time domain granularity may be a radio frame, a subframe, a time slot, a symbol, or a combination of these granularities, and the like. In an FBE-based network, the first reserved time interval is dependent on COT in a Fixed Frame Period, and the location configuration of a single first reserved time interval may be in the form of an offset relative to the starting time of the Fixed Frame Period, where the offset may be a specific time, a number of slots, a number of symbols, or a combination of these forms.

The above-mentioned neighboring cell may be understood as a neighboring cell of the current serving cell, and further may be a strongest interfering neighboring cell of the current serving cell. The at least one first reserved time interval of the current serving cell may be understood as some time intervals reserved on the wireless channel by the current serving cell, and used for the terminal device of the neighboring cell operating on the wireless channel to perform LBT sensing to access the wireless channel and start uplink transmission.

Step 102: and carrying out resource allocation by utilizing the target resource.

The target resource is a resource except a resource corresponding to the at least one first reserved time interval in uplink resources. The uplink resource may be understood as a set of all resources available for uplink scheduling in the current serving cell.

The resource allocation method of the embodiment of the invention performs resource allocation by using the target resource, wherein the target resource is the resource except the resource corresponding to the first reserved time interval in the uplink resource, the first reserved time interval is used for the terminal equipment of the adjacent cell to execute LBT interception, and the resource corresponding to the first reserved time interval can be avoided when resource allocation is performed, so that the success rate of the terminal equipment of the adjacent cell to execute LBT is improved, the probability of mutual blocking among the cells is reduced, and the channel use efficiency is improved.

In the embodiment of the present invention, when the network device performs resource allocation, in addition to considering the resource allocation information of the current serving cell, the network device may also consider the resource allocation information of the neighboring cell (for example, the strongest interfering neighboring cell) to reasonably utilize the time interval reserved by the neighboring cell, thereby improving the success rate of performing LBT by the terminal device allocated with the uplink transmission resource.

Optionally, the configuration information in step 101 may include, in addition to the first resource configuration information of the current serving cell, second resource configuration information of the neighboring cell. The second resource configuration information includes second indication information, where the second indication information is used to indicate at least one second reserved time interval of the neighboring cell, and the second reserved time interval is used for the terminal device of the current serving cell to perform LBT listening.

For the resource corresponding to the second reserved time interval, the resource may be a downlink resource of the neighboring cell, for example, the resource is suitable for a scenario in which the uplink and downlink resources of the current serving cell and the neighboring cell do not correspond to each other, or the resource may be an uplink resource of the neighboring cell, for example, the resource is suitable for a scenario in which the uplink and downlink resources of the current serving cell and the neighboring cell correspond to each other.

The sensing time interval of the target resource in the above step 102 at least partially overlaps with the second reserved time interval. Namely, when allocating resources for the terminal device, the time interval reserved by the neighboring cell is fully considered, thereby ensuring the success rate of the LBT listening of the terminal device. For example, in a specific implementation, the uplink grant resource allocated to the terminal device may start from the end of a certain reserved time interval of the strongest interfering neighbor cell, that is, the listening time interval of the uplink grant resource utilizes the corresponding reserved time interval.

It should be noted that the content indicated by the second indication information may include: the number of second reserved time intervals, the position and length of each second reserved time interval, and the like. In a communication system using an unlicensed frequency band, the second reserved time interval belongs to a certain COT acquired by an LBT in a neighboring cell, and the location configuration of a single second reserved time interval may be in the form of a system time domain granularity index, where the time domain granularity may be a radio frame, a subframe, a time slot, a symbol, or a combination of these granularities, and the like. In an FBE-based network, the second reserved time interval is dependent on COT in a Fixed Frame Period, and the location configuration of a single second reserved time interval may be in the form of an offset relative to the starting time of the Fixed Frame Period, where the offset may be a specific time, a number of slots, a number of symbols, or a combination of these forms.

For example, when the network device performs uplink scheduling, for each UE having uplink resource allocation requirements in the current serving cell, it may first identify a neighboring cell where an interference source that may strongly interfere with uplink transmission of the UE is located, and form a strong interference neighboring cell list; then, when allocating uplink resources to the UE, based on the reserved time interval of the current serving cell and the reserved time interval of the strongest interfering neighbor cell, the uplink resources allocated to the UE start from the end of the reserved time interval of the strongest interfering neighbor cell, for example, so as to reduce the probability of being blocked due to strong interference on the corresponding channel during uplink transmission of the UE, and meanwhile, the uplink resources allocated to the UE do not occupy all actually valid reserved time intervals of the cell, thereby avoiding affecting LBT monitoring of the UE in the neighbor cell. And when the strong interference neighbor cell list of the UE is empty, the starting time of the allocated uplink resource is not limited.

In a specific implementation, the duration of the reserved time interval (i.e., the first reserved time interval and the second reserved time interval) is to be ensured to accommodate the LBT duration in the COT, and a value may be uniformly specified as a certain fixed value, such as a length of a single symbol, 25 μ s (Category 2LBT duration), and the like, and may also be configured by the cell and broadcast in the system information.

In this embodiment of the present invention, when the configuration information includes first resource configuration information of a current serving cell, step 101 may include any one of the following:

acquiring predefined first resource configuration information;

acquiring first resource configuration information configured for a current serving cell; in this way, the first resource allocation information can be directly planned and allocated for the current serving cell based on network parameters and the like, and the corresponding reserved time interval can be dynamically adjusted;

determining first resource configuration Information according to received cell system Information or cell-level Downlink Control Information (DCI) of an adjacent cell; in specific implementation, the cell system information or the cell-level DCI may be broadcast on a radio channel, so that the current serving cell monitors the settings of other neighboring cells in the surrounding environment when being started, and selects corresponding resource configuration information by itself (for example, selects a reserved time interval configuration different from the strongest interfering neighboring cell to stagger the actually valid reserved time interval from the neighboring cell), and after being started, the acquired resource configuration information may be updated as needed;

determining first resource configuration information according to information interacted in the process of establishing an interface with an adjacent cell;

determining first resource configuration information according to information negotiated or notified through an interface; the interface is an interface established between the current serving cell and the neighboring cell, and for example, after the interface is established, when the configuration information changes, the interface may negotiate or notify the corresponding resource configuration information.

In specific implementation, the resource configuration information of the current serving cell related to the reserved time interval may be explicitly obtained by other neighboring cells, so that the corresponding reserved time interval is fully and reasonably utilized based on the configuration information, and a manner that the resource configuration information of the current serving cell related to the reserved time interval is not explicitly obtained by other neighboring cells may also be considered, and at this time, no learning mechanism needs to be considered, so that signaling overhead between cells may be saved, or introduction of a scheme design for mutual learning may be avoided.

Optionally, when the first resource configuration information of the current serving cell may be explicitly obtained by the neighboring cell, the first resource configuration information may be explicitly obtained by the neighboring cell in any one of the following manners:

predefining; under the predefinition, the interaction of explicit signaling among the cells is not needed, and possible implementation modes of the method comprise protocol unified regulation, a reserved time interval pattern adopted by a corresponding cell is determined based on cell identification and the like;

network configuration; in this way, the configuration information of a certain adjacent cell and the adjacent cells can be directly planned and configured based on network parameters and the like, and the configuration information comprises the first resource configuration information of the current service cell without information interaction among the cells;

broadcasting on a wireless channel through cell system information;

indicated by cell-level DCI; the cell-level DCI may scramble a Radio Network Temporary Identity (RNTI), and the cell-level RNTI is adopted;

negotiating or informing in the process of establishing an interface with a neighbor cell or negotiating or informing through the interface when the configuration information changes after the interface is established.

The first resource allocation information of the current serving cell may be obtained in different manners based on whether the resource allocation information is explicitly obtained between the neighboring cells, which is described in detail below.

When the resource configuration information can be explicitly obtained between the adjacent cells, the manner of obtaining the first resource configuration information of the current serving cell may include any one of the following:

acquiring predefined first resource configuration information; under the predefinition, the interaction of explicit signaling among the cells is not needed, and possible implementation modes of the method include that a protocol uniformly stipulates the configuration of the reserved time interval, the reserved time interval pattern adopted by the corresponding cell is determined based on the cell identifier, and the like;

determining first resource configuration information according to the received cell system information or cell-level DCI of the adjacent cell; in specific implementation, the cell system information or the cell-level DCI may be broadcast on a radio channel, so that the current serving cell monitors the settings of other neighboring cells in the surrounding environment when being started, and selects corresponding resource configuration information by itself; after starting, the acquired resource configuration information can be updated according to the requirement;

When the resource configuration information cannot be explicitly obtained between the adjacent cells, the manner of obtaining the first resource configuration information of the current serving cell may include any one of the following:

acquiring predefined first resource configuration information; the predefined scheme herein may include that the protocol specifies that the terminal device reserves the behavior of the time interval when occupying the channel (e.g., a time interval is set to 25us, a single or multiple symbol duration, a single or multiple TTI duration, or other time length capable of accommodating some sort of LBT operation duration, etc., when a certain transmission position is satisfied, or when a certain duration is satisfied per occupied radio channel);

acquiring first resource configuration information configured for a current serving cell; in this way, the first resource allocation information can be directly planned and allocated for the current serving cell based on network parameters and the like, and the corresponding reserved time interval can be dynamically adjusted.

In this embodiment of the present invention, when the configuration information includes second resource configuration information of a neighboring cell, step 101 may include any one of the following:

acquiring predefined second resource configuration information; under the predefinition, the interaction of explicit signaling among the cells is not needed, and possible implementation modes of the method comprise protocol unified regulation, a reserved time interval pattern adopted by a corresponding cell is determined based on cell identification and the like;

acquiring second resource configuration information configured for the current serving cell; in this way, the neighboring cell and the configuration information of the neighboring cell can be directly planned and configured for the current serving cell based on network parameters and the like, the reserved time interval is dynamically adjusted, and information interaction among cells is not needed;

determining second resource configuration information according to the received cell system information or cell-level DCI of the neighboring cell; in specific implementation, the cell system information or the cell-level DCI may be broadcast on a radio channel, so that the current serving cell monitors the settings of other neighboring cells in the surrounding environment when being started, determines resource configuration information of the corresponding neighboring cell, and may update the acquired configuration information as needed after being started;

determining second resource configuration information according to information (namely, negotiated information) interacted in the process of establishing an interface with an adjacent cell;

acquiring second resource configuration information according to the information negotiated or notified through the interface; the interface is an interface established between the current serving cell and the neighboring cell, that is, after the interface is established, when the configuration information changes, the interface may negotiate or notify the corresponding resource configuration information.

In the embodiment of the present invention, the method further includes any one of:

sending the first resource configuration information to terminal equipment through cell system information;

sending the first resource configuration information to terminal equipment through RRC signaling;

sending the first resource configuration information to terminal equipment through cell-level DCI;

transmitting a first DCI to the terminal device;

the first reserved time interval is used for determining a reserved time interval which cannot be occupied by uplink transmission of the terminal equipment; the first DCI includes third indication information, where the third indication information is used to indicate a reserved time interval that cannot be occupied by uplink transmission of the terminal device.

Therefore, when receiving the uplink grant resource and starting the corresponding LBT and uplink transmission, the terminal device can acquire and follow the reserved time interval related to the uplink transmission, thereby achieving the following effects: in the related reserved time interval, if the reserved time interval is located in the uplink transmission time period, the terminal device in the cell does not have any occupation behavior aiming at the specified channel.

Because the interference of the cell center terminal equipment to the adjacent cell is generally small, the interference of the uplink transmission initiated by the cell center terminal equipment to the adjacent cell is generally small, the interference of the cell edge terminal equipment to the adjacent cell is large, and the interference of the uplink transmission initiated by the cell edge terminal equipment to the adjacent cell is generally large, the resource allocation method of the embodiment of the invention can be preferably applied to the cell edge terminal equipment, and the terminal equipment can be selected as the cell edge terminal equipment.

Optionally, the step 102 may include:

and distributing resources for the cell edge terminal equipment of the current service cell by using the target resources.

Thus, the following effects can be achieved: in the related reserved time interval, if the reserved time interval is located in the uplink transmission time period, the cell edge terminal equipment in the cell does not have any occupation behavior aiming at the specified channel.

In the embodiment of the present invention, when performing step 101, the network device may determine, according to the cell identifier, a reserved time interval pattern corresponding to the cell identifier; the cell identifier is a cell identifier of a current serving cell or a neighboring cell. I.e. this way of determining the reserved time interval pattern is equally applicable to the current serving cell and the neighbor cells.

Optionally, the Index Pattern _ Index of the reserved time interval Pattern may be:

the Cell ID mod Pattern _ Num, that is, the reserved time interval Pattern adopted by each Cell may be determined in a manner of Cell ID mod Pattern _ Num;

an Index TTI _ Index of a Transmission Time Interval (TTI) where a reserved Time Interval in the reserved Time Interval pattern is located is:

TTI_Index＝(Pattern_Num*n+Pattern_Index)*Pattern_Interval；

wherein, the Cell ID is a Cell identifier; the Pattern _ Num is the number of the selectable patterns; the Pattern _ Interval is a number of TTIs between corresponding reserved time intervals of adjacent patterns in the selectable Pattern; n is an integer greater than or equal to 0, and the TTI Duration TTI _ Duration (which may correspond to a subframe, a Slot, a Mini-Slot, or other time domain resource granularity) corresponding to the TTI _ Index is located within the channel occupancy time COT or within the uplink period of the COT; mod is the sign of the modulo operation.

Further, the position of the reserved time interval in the reserved time interval pattern may satisfy any one of the following conditions:

the starting time of the reserved time interval is aligned with the starting time of the TTI _ Duration corresponding to the corresponding TTI _ Index;

the end time of the reserved time interval is aligned with the end time of the TTI _ Duration corresponding to the corresponding TTI _ Index;

the end time of the reserved time interval is aligned with the end time of the last TTI _ Duration (when present) of the TTI _ Duration corresponding to the corresponding TTI _ Index.

The length of a single reserved time interval may be set to 25us, a single symbol duration, or other length of time that can accommodate some sort of LBT operation duration.

The resource allocation procedure in the embodiment of the present invention is described below with reference to fig. 2.

In the specific example of the present invention, as shown in fig. 2, on an unauthorized frequency point, a single operator deploys an FBE-based network, the deployment of each cell is planned to work in a synchronized state in a unified manner, and the Fixed Frame Period configuration and the Frame Period timing are completely the same; the reserved time interval of each Cell is determined in a predefined manner, and a reserved time interval Pattern adopted by the corresponding Cell is determined based on the Cell identifier, for example, the reserved time interval Pattern adopted by the Cell is determined in a Cell ID modulo Pattern _ Num manner.

At this time, as shown in fig. 2, Pattern _ Num is 3, Pattern _ Interval is 1, each of the cells a, B, and C uses a reserved time Interval Pattern, and the Pattern _ indexes of the cells a, B, and C are just staggered, for example, the Pattern _ Index of the cell a is 0, the Pattern _ Index of the cell B is 1, and the Pattern _ Index of the cell C is 2.

In fig. 2, a maximum of 9 TTIs can be used in the COT within a single frame period, and in order to avoid interference between uplink and downlink transmission directions within the system, each cell adopts the same configuration for each TTI or the transmission direction with smaller time granularity within the TTI, where downlink transmission can be performed in the first 4 TTIs within the single frame period, and uplink transmission can be performed in the remaining 5 subsequent TTIs. For cell a, the Index TTI _ Index of the TTI in which the reserved time interval in the reserved time interval pattern is located is 6 (as an example, a local TTI Index manner within a single frame period is adopted here, and numbering is started from 0), and the start time of the reserved time interval is aligned with the start time of this TTI; for cell B, the indexes TTI _ Index of the TTI where the reserved time interval in the reserved time interval pattern is located are 4 and 7, and the start time of the reserved time interval is aligned with the start time of this TTI; for cell C, the indices TTI _ Index of the TTI in which the reserved time interval in the reserved time interval pattern is located are 5 and 8, and the start time of the reserved time interval is aligned with the start time of this TTI.

For UE a1, UE a2, UE A3 and UE a4 in cell a, which have uplink resource allocation requirements, since cell B is the strongest interference neighbor cell of UE a1 and UE A3, UE a2 is in the center of the cell (i.e. the interfered cell), and cell C is the strongest interference neighbor cell of UE a4, when allocating resources for UE a1 during uplink scheduling, the uplink resources of UE a1 may be allocated from the end position of the reserved time interval where cell B is located at the beginning of TTI 4 (since TTI _ Index corresponding to this reserved time interval is 4, it may be referred to as reserved time interval TTI _ Index 4 subsequently); when allocating resources for UE a2, TTI 6 may be occupied but reserved time interval TTI _ Index 6 of cell a is avoided, which reserved time interval TTI _ Index 6 may be used for LBT listening for UE a 2; when allocating resources for UE A3, uplink resources for UE A3 may be allocated starting from the end position of the reserved time interval TTI _ Index 7 of cell B; when allocating resources for UE a4, uplink resources for UE a4 may be allocated starting from the end position of the reserved time interval TTI _ Index 8 of cell C.

For UE B1, UE B2, UE B3 and UE B4 in cell B, which have uplink resource allocation requirements, because UE B1 and UE B4 are located in the center of the cell (i.e., are subjected to small interference), cell C is the strongest interference neighbor cell of UE B2, and cell a is the strongest interference neighbor cell of UE B3, when allocating resources for UE B1 in uplink scheduling, TTI 4 may be occupied but reserved time interval TTI _ Index 4 of cell B is avoided, and this reserved time interval TTI _ Index 4 may be used for LBT listening of UE B1; when allocating resources for UE B2, uplink resources for UE B2 may be allocated starting from the end position of the reserved time interval TTI _ Index 5 of cell C; when allocating resources for UE B3, uplink resources for UE B3 may be allocated starting from the end position of the reserved time interval TTI _ Index 6 of cell a; when allocating resources for UE B4, TTI 7 and TTI 8 may be occupied but cell B's reserved time interval TTI _ Index 7 is avoided, which reserved time interval TTI _ Index 7 may be used for LBT listening for UE B4.

For UE C1, UE C2, UE C3 and UE C4 in cell C, which have uplink resource allocation requirements, since cell B is the strongest interfering neighbor cell of UE C1 and UE C4, UE C2 is in the cell center (i.e. the interfered cell), and cell a is the strongest interfering neighbor cell of C3, when allocating resources for UE C1 in uplink scheduling, the uplink resources of UE C1 may be allocated starting from the end position of the reserved time interval TTI _ Index 4 of cell B; when allocating resources for UE C2, a reserved time interval TTI _ Index 5 that may occupy TTI 5 but avoid cell C, which reserved time interval TTI _ Index 5 may be used for LBT listening for UE C2, and a reserved time interval TTI _ Index 8 that occupies TTI 8 but avoid cell C, which reserved time interval TTI _ Index 8 may be used for LBT listening for UE C2; when allocating resources for UE C3, uplink resources for UE C3 may be allocated starting from the end position of the reserved time interval TTI _ Index 6 of cell a; when allocating resources for UE C4, uplink resources for UE C4 may be allocated starting from the end position of the reserved time interval TTI _ Index 7 of cell B.

Thus, when the UE has the strongest interference neighbor cell, the uplink resource of the UE is allocated from the end time of the reserved time interval of the strongest interference neighbor cell, so that the probability of blockage caused by the strong interference on the corresponding channel during the uplink transmission of the UE can be reduced; in addition, the allocation of UE uplink resources does not occupy all the actually effective reserved time intervals of the cell, so that the influence on the LBT interception of the UE of the adjacent cell can be avoided, the probability of mutual blocking among the cells is reduced, and the use efficiency of the channel is improved.

Referring to fig. 3, fig. 3 is a flowchart of another resource allocation method according to an embodiment of the present invention, where the method is applied to a network device, and as shown in fig. 3, the method includes the following steps:

step 301: and acquiring second resource configuration information of the adjacent cell.

Wherein the second resource configuration information includes second indication information, the second indication information is used to indicate at least one second reserved time interval of the neighboring cell, and the second reserved time interval is used for the terminal device of the current serving cell to perform LBT listening.

For a detailed description of the second resource allocation information, the second indication information, and the second reserved time interval, reference may be made to the embodiment in fig. 1, which is not described herein again.

Step 302: and carrying out resource allocation by utilizing the target resource.

Wherein the listening time interval of the target resource at least partially overlaps with the second reservation time interval. For example, in a specific implementation, the uplink grant resource allocated to the terminal device may start from the end of a certain reserved time interval of the strongest interfering neighbor cell, that is, the listening time interval of the uplink grant resource utilizes the corresponding reserved time interval.

The resource allocation method of the embodiment of the invention can fully consider the time interval reserved by the adjacent cell when allocating the resources for the terminal equipment, thereby ensuring the success rate of LBT interception of the terminal equipment.

Optionally, step 301 may include:

acquiring second resource configuration information configured for the current serving cell; in this way, the time interval reserved by the cell can be dynamically adjusted based on network parameters and the like; in this way, the neighboring cell and the configuration information of the neighboring cell can be directly planned and configured for the current serving cell based on network parameters and the like, the reserved time interval is dynamically adjusted, and information interaction among cells is not needed;

determining second resource configuration information according to the received cell system information or cell-level DCI of the neighboring cell; in a specific implementation, the cell system information or the cell-level DCI may be broadcast on a radio channel, so that the current serving cell monitors the settings of other neighboring cells in the surrounding environment when being started, and determines resource configuration information of the corresponding neighboring cell; after the starting, the acquired configuration information can be updated according to the requirement;

Optionally, the method further comprises any one of the following:

sending first resource configuration information of a current service cell to terminal equipment through cell system information;

sending first resource configuration information of a current serving cell to terminal equipment through RRC signaling;

sending first resource configuration information of a current service cell to terminal equipment through cell-level DCI;

transmitting a first DCI to the terminal device;

the first resource configuration information includes first indication information, where the first indication information is used to indicate at least one first reserved time interval of a current serving cell, and the first reserved time interval is used for a terminal device to determine a reserved time interval that cannot be occupied by uplink transmission of the terminal device;

the first DCI includes third indication information, where the third indication information is used to indicate a reserved time interval that cannot be occupied by uplink transmission of the terminal device.

Therefore, when receiving the uplink grant resource and starting the corresponding LBT and uplink transmission, the terminal device can acquire and follow the reserved time interval related to the uplink transmission.

Referring to fig. 4, fig. 4 is a flowchart of an uplink transmission method provided in an embodiment of the present invention, where the method is applied to a terminal device, and as shown in fig. 4, the method includes the following steps:

step 401: and receiving the uplink authorization information.

Step 402: and determining a reserved time interval corresponding to uplink transmission.

Wherein the reserved time interval is used for the neighbor cell terminal equipment to perform LBT listening.

Step 403: performing LBT listening for a target resource; and the target resource is a resource except the resource corresponding to the reserved time interval in the uplink authorized resources indicated by the uplink authorized information.

Step 404: and when the LBT interception is successful, carrying out uplink transmission.

The uplink transmission method of the embodiment of the invention executes LBT interception aiming at target resources, and carries out uplink transmission when the LBT interception is successful, the target resources are resources except the resources corresponding to the reserved time interval in the uplink authorization resources, and the resources corresponding to the reserved time interval can be avoided when carrying out uplink transmission, thereby improving the success rate of executing LBT by the terminal equipment of the adjacent cell, reducing the probability of mutual blocking among the cells and improving the use efficiency of the channel.

It can be understood that, in a specific implementation, if the network device comprehensively considers the reserved time interval of the current serving cell and the reserved time interval of the neighboring cell when allocating resources to the terminal device, the terminal device may directly perform LBT interception and uplink transmission on the uplink grant resources without additionally performing inference (i.e., determination) and avoidance related to the reserved time interval after obtaining the uplink grant resources.

In the embodiment of the present invention, because the cell center terminal device is generally less interfered by the neighboring cell, the interference of the uplink transmission initiated by the cell center terminal device to the neighboring cell is generally less, and the interference of the cell edge terminal device is greater by the neighboring cell, and the interference of the uplink transmission initiated by the cell edge terminal device to the neighboring cell is generally greater, the uplink transmission method of the embodiment of the present invention can be preferably applied to the cell edge terminal device, and the terminal device can be selected as the cell edge terminal device.

Optionally, step 402 may include:

judging whether the terminal equipment is cell edge terminal equipment or not;

and when the terminal equipment is cell edge terminal equipment, determining the reserved time interval.

Thus, the following effects can be achieved: if the reserved time interval is located in the uplink transmission time period, the cell edge terminal equipment does not have any occupation behavior aiming at the specified channel in the related reserved time interval, the probability of mutual blocking among the cells is reduced, and the channel use efficiency is improved.

Optionally, the determining whether the terminal device is a cell edge terminal device may include:

judging whether the terminal equipment is cell edge terminal equipment or not according to a channel quality threshold value and a channel state of the terminal equipment;

The channel Quality threshold may be a Reference Signal Receiving Power (RSRP) threshold, a Reference Signal Receiving Quality (RSRQ) threshold, or both.

For example, when the RSRP of the terminal device is lower than the RSRP threshold, it may be determined that the terminal device is a cell edge terminal device; or when the RSRQ of the terminal equipment is lower than the RSRQ threshold value, the terminal equipment can be judged to be cell edge terminal equipment; or when the RSRP of the terminal device is lower than the RSRP threshold value and the RSRQ of the terminal device is lower than the RSRQ threshold value, it may be determined that the terminal device is a cell edge terminal device.
