Description

Communication method and device

Technical Field

The present application relates to the field of communications, and, more particularly, to a method and apparatus for transmitting data.

Background

With the development of communication, the fifth generation (5th generation,5G) communication system gradually permeates multimedia services with strong real-time performance and large data capacity requirements, such as video transmission, cloud Gaming (CG), extended reality (XR), and the like. The delay of data transmission and the integrity of data transmission are required to be strict by multimedia services, so how to determine the location of data transmission resources in the communication process is a problem to be considered.

Disclosure of Invention

The application provides a communication method for determining the position of a data transmission time domain resource in a communication process.

In a first aspect, a communication method is provided, which may be performed by a network device or a terminal device, may be performed by a component (e.g. a processor, a chip or a chip system) of the network device or the terminal device, or may be implemented by a logic module or software that is capable of implementing all or part of the functions of the network device or the terminal device. The method comprises the following steps: obtaining the configuration period duration of the configuration resource; and transmitting or receiving data on a first time domain resource unit, wherein the position of the first time domain resource unit is determined by a bias parameter and the configuration period duration of the configuration resource, and the value of the bias parameter is related to the time division duplex TDD time slot configuration.

In the present application, the configuration resource is a resource configured for transmitting service related data, where the configuration resource includes a first time domain resource unit, and a position of the first time domain resource unit may be represented with a time slot or a symbol as granularity. The configuration resource and the first time domain resource unit can be used for uplink transmission data, which means that the terminal equipment sends data to the network equipment or the network equipment receives data from the terminal equipment, or can be used for downlink transmission data, which means that the network equipment sends data to the terminal equipment or the terminal equipment receives data from the network equipment.

In the present application, the configuration period of the configuration resource is an ideal period pre-configured before transmitting data, in an actual transmission process, a time slot or a symbol corresponding to a position of a first time domain resource unit determined according to the period may not be able to transmit or receive data, and in order to ensure normal transmission of data, the position of the first time domain resource unit needs to be adjusted by a bias parameter to meet a transmission requirement, so that periodic data transmission is not necessarily performed completely according to the configuration period in the actual transmission process.

For example, when data needs to be transmitted in a downlink manner through the first time domain resource unit, the position of the first time domain resource unit determined according to the configuration period duration of the configuration resource corresponds to an uplink slot (U slot), but the network device needs to send data to the terminal device in a downlink slot (Dslot), so that the position of the first time domain resource unit can be adjusted to the position corresponding to the downlink slot through the bias parameter in order not to miss the data.

In one possible implementation manner, after obtaining the configuration period duration of the configuration resource and before transmitting or receiving the data, the method may further include calculating a position of the first time domain resource unit according to the configuration period duration of the configuration resource, and judging whether the position of the first time domain resource unit can meet the requirement of transmitting or receiving the data, if so, transmitting or receiving the data on the first time domain resource unit; if the offset parameter cannot be met, the position of the first time domain resource unit is updated according to the offset parameter, and data is sent or received on the updated first time domain resource unit. The slots include U slots, D slots and special slots (S slots), the U slots include uplink symbols (uplink symbols) and flexible symbols (flexible symbols), the dsslots include downlink symbols (downlink symbols) and flexible symbols, the S slots include uplink symbols, downlink symbols and flexible symbols, wherein the uplink symbols are used for transmitting symbols of uplink data, the downlink symbols are used for transmitting symbols of downlink data, the flexible symbols are configured as symbols for either downlink or uplink transmission, and in general, the flexible symbols in the U slots are configured as symbols for transmitting uplink data, and the flexible symbols in the D slots are configured as symbols for transmitting downlink data. Illustratively, in D slot, the UE should assume that the downlink transmission occurs only in downlink symbols or flexible symbols; in the U slot, the UE can only transmit with uplink symbols or flexible symbols. The fact that the position of the first time domain resource unit meets the requirement of sending or receiving data means that if downlink data transmission is needed, the position of the first time domain resource unit corresponds to a downlink symbol in a D slot or an S slot or a flexible symbol configured for transmitting the downlink data; if uplink data transmission is required, the position of the first time domain resource unit corresponds to an uplink symbol in a Uslot or S slot or a flexible symbol configured to be used for transmitting uplink data.

By the method, the situation that the time slot or the symbol corresponding to the determined position of the first time domain resource unit does not accord with the requirement of data transmission can be avoided, so that the data can be normally transmitted, and the reliability of data transmission is improved.

With reference to the first aspect, in certain implementations of the first aspect, the TDD time slot configuration corresponds to candidate values of one or more bias parameters, the value of the bias parameter being one of the candidate values.

The value of the offset parameter may be a distance between a time slot corresponding to the position determined according to the configuration period duration and an available time slot, or a distance between a symbol corresponding to the position determined according to the configuration period duration and an available symbol, where the value of the offset parameter may be granularity of the time slot or the symbol.

Specifically, taking the granularity of the time slots as an example, the above available time slots refer to time slots meeting the data transmission requirement, further, may refer to time slots meeting the data transmission requirement closest to the time slots, and further, may refer to time slots meeting the data transmission requirement closest to the time slots and unoccupied. In this application, for a slot satisfying the data transmission requirement, refer to the description that the slot type corresponding to the position of the first time domain resource unit satisfies the requirement of transmitting or receiving data.

Because the offset parameter corresponds to the TDD time slot configuration, the offset parameter may enable the first time domain resource unit to meet the requirement of transmitting data, thereby improving reliability and accuracy of data transmission.

With reference to the first aspect, in some implementations of the first aspect, a configuration period duration of the configuration resource is equal to a period duration of a service corresponding to the data.

If the configuration resource is used for downlink data transmission, the network device can acquire the period duration of the service through the configuration information of the service quality (quality of service, qoS) flow, and send the period duration of the service to the terminal device; if resources are configured for uplink data transmission, the terminal equipment can acquire the period duration of the service through interlayer interaction and send the period duration of the service to the network equipment.

The time delay of the service can be reduced by determining the position of the first time domain resource unit by using the period duration of the service corresponding to the data.

The wearable device can also be called as a wearable intelligent device, and is a generic name for intelligently designing daily wearing and developing wearable devices by applying a wearable technology, such as glasses, gloves, watches, clothes, shoes and the like. The wearable device is a portable device that is worn directly on the body or integrated into the clothing or accessories of the user. The wearable device is not only a hardware device, but also can realize a powerful function through software support, data interaction and cloud interaction. The generalized wearable intelligent device includes full functionality, large size, and may not rely on the smart phone to implement complete or partial functionality, such as: smart watches or smart glasses, etc., and focus on only certain types of application functions, and need to be used in combination with other devices, such as smart phones, for example, various smart bracelets, smart jewelry, etc. for physical sign monitoring.

The network device may be a device in a wireless network. For example, the network device may be a device deployed in a radio access network to provide wireless communication functionality for terminal devices. For example, the network device may be a radio access network (radio access network, RAN) node, also referred to as access network device, that accesses the terminal device to the wireless network.

The network devices include, but are not limited to: an evolved Node B (eNB), a radio network controller (radio network controller, RNC), a Node B (Node B, NB), a base station controller (base station controller, BSC), a base transceiver station (base transceiver station, BTS), a home evolved Node B, heNB, or home Node B, HNB), a Base Band Unit (BBU), a server, a wearable device, an in-vehicle device, an Access Point (AP) in a WIFI system, a radio relay Node, a radio backhaul Node, a transmission point (transmission point, TP), or a transmission reception point (transmission and reception point, TRP), etc., may also be 5G, such as a gNB in an NR system, or a transmission point (TRP or TP), one or a group of antenna panels (including a plurality of antenna panels) of a base station in a 5G system, or may also be a network Node constituting a gNB or a transmission point, such as a Base Band Unit (BBU), or a Distributed Unit (DU), etc. The base station may be a macro base station, a micro base station, a pico base station, a small station, a relay station, a balloon station, or the like.

The AAU realizes part of physical layer processing function, radio frequency processing and related functions of the active antenna. The information of the RRC layer is generated by the CU and finally becomes PHY layer information through PHY layer encapsulation of DU, or is converted from the information of the PHY layer. Thus, under this architecture, higher layer signaling, such as RRC layer signaling, may also be considered to be sent by DUs, or by dus+aaus. It is understood that the network device may be a device comprising one or more of a CU node, a DU node, an AAU node. In addition, the CU may be divided into network devices in an access network (radio access network, RAN), or may be divided into network devices in a Core Network (CN), which is not limited in this application.

Today, with the continuous development of the fifth generation (5G) communication system, the data transmission delay is continuously reduced, the transmission capacity is increasingly larger, and the 5G communication system gradually permeates some multimedia services with strong real-time performance and large data capacity requirement, such as video transmission, cloud Game (CG), augmented Reality (XR), and the like, where XR includes Virtual Reality (VR) and augmented Reality (augmented Reality, AR).

The requirements of the multimedia service on the power consumption control and the data transmission quality of the terminal equipment are more and more strict. Taking XR and video transmission as examples, in view of the fact that the traffic model usually arrives periodically according to the frame rate, in order to reduce the power consumption of the terminal device side, semi-persistent scheduling (SPS) transmission is usually used in downlink transmission, and Configuration Grant (CG) transmission is usually used in uplink transmission. In this application, configuring grants may also be referred to as unlicensed scheduling. Therefore, under the condition of reducing power consumption, the position of the data transmission resource can be accurately determined, the integrity of the transmitted data is ensured, the quality of the data transmission is further improved, and the high-quality realization of the service is ensured.

Based on SPS transmission and CG transmission, configuration resources can be allocated or appointed once through RRC or PDCCH, and then the same time-frequency resources can be periodically reused for uplink transmission, so that the expenditure of signaling is effectively reduced. The period duration of the SPS resource may be an integer multiple of the slot length, the period duration of the CG resource may be an integer multiple of 2 symbols, 7 symbols or 14 symbols, but the period duration of the service may not be an integer multiple of the slot length or may not be an integer multiple of 2/7/14 symbols, which may result in that the period duration of the configuration resource and the period duration of the service are generally not completely equal, and as the number of data transmission increases, the time delay of the service may be increased.

In addition, in the TDD system, the time slot includes a U slot, a D slot, and an S slot, where the number proportion and the sequencing of the U slot, the D slot, and the S slot may be preconfigured, and the number proportion and the sequencing of the uplink symbol, the downlink symbol, and the flexible symbol in the S slot may be preconfigured, and the attribute of the flexible symbol may also be preconfigured. The network equipment receives data from the terminal equipment on an uplink symbol of the U slot or the S slot or a flexible symbol configured for transmitting uplink data, and transmits data to the terminal equipment on a downlink symbol of the D slot or the S slot or a flexible symbol configured for transmitting downlink data; the terminal device receives data from the network device on a downlink symbol of the D slot or the S slot or a flexible symbol configured for transmitting downlink data, and transmits data to the network device on an uplink symbol of the U slot or the S slot or a flexible symbol configured for transmitting uplink data. The first time domain resource unit, which is determined only according to the configuration period of the configuration resource, may not be used for transmitting data, resulting in data retransmission.

Illustratively, as shown in fig. 2, in the case where the time slot of the TDD is configured as a DDDUU, where D is a downlink time slot and U is an uplink time slot. If the time slot number of the first time domain resource unit determined by the network device according to the configuration period of the configuration resource is 3, and data is sent to the terminal device on the first time domain resource unit, the data will be missed because the first time domain resource unit does not have the capability of transmitting data in a downlink at this time. Similarly, if the time slot number of the first time domain resource unit determined by the network device according to the configuration period of the configuration resource is 2, and the data from the terminal device is received on the first time domain resource unit, the data will be missed because the first time domain resource unit does not have the capability of uplink data transmission at this time.

That is, in a TDD system, in order to ensure reliability and integrity of data transmission, a bias parameter should be considered when determining the location of the first time domain resource unit, where the bias parameter has a value related to the timeslot configuration of TDD.

Illustratively, the TDD time slot is configured as a DDDSU, and for downlink transmission, in one possible implementation, the first list obtained from the TDD time slot configuration is shown in the following table. If the symbol corresponding to the position of the first time domain resource unit is judged to be a downlink symbol in S slot or a flexible symbol configured for transmitting downlink data, the value of the bias parameter is 0; if the symbol corresponding to the position of the first time domain resource unit is judged to be an uplink symbol in the S slot or a flexible symbol configured for transmitting uplink data, the value of the offset parameter is 2.

Time slot configuration	D	D	D	S	U
						Candidate value	0	0	0	0 or 2	1

In one possible implementation, the first list obtained according to the TDD slot configuration is shown in the following table. The position of the first time domain resource unit corresponds to a downlink symbol in the S slot.

Time slot configuration	D	D	D	S	U

The method in the embodiment of the application can take the period duration of the service as the configuration period duration of the configuration resource, thereby shortening the service delay, considering the influence of TDD time slot configuration on data receiving and transmitting, improving the success rate of communication and improving the communication quality.

Fig. 4 is an interaction flow chart of a communication method provided in an embodiment of the present application. The method is illustrated in fig. 4 by taking the network device and the terminal device as the execution bodies of the interactive instruction, but the application is not limited to the execution bodies of the interactive instruction. For example, the network device in fig. 4 may also be a chip, a system-on-a-chip, or a processor that supports the network device to implement the method, or may be a logic module or software that can implement all or part of the functions of the network device; the terminal device in fig. 4 may also be a chip, a system-on-chip, or a processor supporting the terminal device to implement the method, or may be a logic module or software capable of implementing all or part of the functions of the terminal device. The method 400 shown in fig. 4 may be used in a TDD system, where the configuration resources in the method 400 are used for downlink data transmission, including:

s410, the network device obtains a configuration period duration of the configuration resource.

The configuration resource is a resource configured by the network device for transmitting data related to service, specifically, the network device configures related parameters of the configuration resource through radio resource control (radio resource control, RRC) signaling, and the related parameters of the configuration resource include an unlicensed scheduling identifier, a configuration period duration of the configuration resource, and a hybrid automatic repeat request process (hybrid automatic repeat requestprocess, harq-process).

Illustratively, the unlicensed scheduling identity may be a configuration scheduling radio network temporary identity (configured scheduling-radio network temporary identifier, CS-RNTI).

In one possible implementation, the network device determines a plurality of sets of parameters of the configuration resource, each set of parameters of the configuration resource corresponding to a service or a period.

The network device obtains the configuration period duration of the configuration resource, and the configuration period duration of the configuration resource can be determined according to the period duration of the service.

Illustratively, the network device obtains a period duration of the service, and the configuration period duration of the configuration resource is equal to the period duration of the service.

Specifically, the network device acquires the period duration of the traffic through the configuration information of the quality of service (quality of service, qoS) flow, and the QoS template (QoS profile) informs the base station of the arrival period of the traffic in QoS, for example.

Specifically, the network device estimates the arrival period of the data packet by detecting the arrival time interval of the data packet in the QoS flow, and presumes the frame rate of the service.

In the embodiment of the present application, the duration of the configuration period of the configuration resource may not be an integer multiple of the time slot, taking the service of 60FPS (frame per second) as an example, the period of the service is 100/3slot, and the duration of the configuration period of the configuration resource may be set to 100/3slot, thereby reducing the time delay of the service and improving the communication quality.

As an example and not by way of limitation, in the embodiment of the present application, the configuration resource is used by the network device to send data to the terminal device or the terminal device to receive data from the network device, where the configuration resource may be an SPS resource, and the configuration of the SPS resource is exemplified as follows, where the periodicity represents a period duration of the configuration, and the FPS represents a frame rate of the configuration:

example #1 (configuration period):

example #2 (configuration frame rate):

where ENUMERATED denotes a parameter of an ENUMERATED type, such as periodicity ENUMERATED { ms10, ms20, ms32, ms40, ms64, ms80} means that the periodicity can be set to one of the above values, spark means that alternatively, inter (1..1024) means that the FPS can be set to an INTEGER in 1-1024.

Before the network device sends data to the terminal device, the network device indicates the specifically activated SPS resources through the PDCCH, specifically, the DCI, and simultaneously indicates the SPS to transmit the specifically allocated frequency domain resources through the resource allocation domain.

Optionally, S420, the network device sends configuration information to the terminal device, where the configuration information indicates a configuration period duration of the configuration resource.

Illustratively, the network device indicates the configuration period duration of the configuration resource through a period field of the RRC signaling.

S430, the network device sends data on the first time domain resource unit, the first time domain resource unit is contained in the configuration resource, and the position of the first time domain resource unit is determined by the bias parameter and the configuration period duration of the configuration resource, wherein the value of the bias parameter is related to the time division duplex TDD time slot configuration.

The network device determines a value of a bias parameter, the value of the bias parameter being associated with a time division duplex, TDD, time slot configuration, in particular, the TDD time slot configuration corresponding to a candidate value of one or more bias parameters, the value of the bias parameter being one of the candidate values.

The network device determines a first list comprising one or more information sets, each information set corresponding to a time slot, each information set comprising a candidate value for a bias parameter and an index, according to a TDD time slot configuration. The network equipment calculates an index value according to the configuration period duration of the configuration resource, and determines a corresponding bias parameter according to the index value, wherein the bias parameter represents the distance between a time slot corresponding to the position determined according to the configuration period duration and an available time slot, and the value of the bias parameter can take the time slot as granularity. Specifically, the available time slots refer to time slots meeting data transmission requirements, further, the available time slots refer to time slots meeting data transmission requirements closest to each other, and further, the available time slots may refer to time slots meeting data transmission requirements closest to each other and unoccupied.

By way of example and not limitation, a time slot of TDD within one period is configured as a DDDUU, where D is a downlink time slot and U is an uplink time slot.

The network device determines an index value according to the configuration of the configuration resource, wherein the index value (slot-index) meets the following conditions: slot-index=int (numberofslotsperframe×sfnstart time+slotstart time+n×periodic x numberOfSlotsPerFrame/i) mod u (r),

wherein r represents the number of time slots contained in one period of time slot configuration, int represents rounding operation, modolu represents modulo operation, N is an integer greater than or equal to 0, periodic represents the configuration period duration of configuration resources, numberofslotsPerframe represents the number of time slots contained in a wireless system frame, i represents the time domain length of the wireless system frame, SFNstart time represents the starting wireless frame number of configuration resources, and slotstart time represents the starting time slot number of configuration resources.

Specifically, N may represent that the network device transmits data to the terminal device for the nth time after initialization, N equals to 0 and represents a location of configuration resource initialization, where the location is represented by the SFNstart time and the slotstart time, for example, the SFNstart time may refer to a radio frame number of the PDSCH starting transmission, and the slotstart time may refer to a slot number of the PDSCH starting transmission. The numberOfSlotsPerFrame indicates the number of slots included in the radio system frame, i indicates the time domain length of the radio system frame, and the value of i may be 10 and the value of numberOfSlotsPerFrame may be 20, for example.

Taking 60FPS as an example, assume sfnsttart time=0, slotstart time=0:

when n=0, slot-index=int (0+0+0) moduu (5) =0;

when n=1, slot-index=int (0+0+100/3) modu (5) =4;

when n=2, slot-index=int (0+0+200/3) modu (5) =2;

when n=3, slot-index=int (0+0+100) moduu (5) =0;

and finding out a corresponding candidate value from the first list according to the slot-index, wherein the candidate value is the value of the bias parameter in the embodiment of the application.

In one possible implementation, the available time slots refer to the time slots closest to the time slot meeting the data transmission requirement, and the network device may obtain the first list as shown in the following table according to the above time slot configuration.

If the calculated slot-index value is 4, the offset parameter value is 1, namely the position of the first time domain unit is moved backwards by one time slot, and the original U slot is changed into D slot, so that the network equipment can send data to the terminal equipment by using the first time domain unit.

Index	0	1	2	3	4
						Time slot configuration	D	D	D	U	U
Candidate value	0	0	0	2	1

In one possible implementation manner, the available time slots refer to the time slots which are closest to and unoccupied and meet the data transmission requirement, the network device can obtain a first list shown in the following table according to the time slot configuration, when determining the candidate value, the first list considers the situation that a plurality of groups of data transmission exist on the configuration resource at the same time, if the value corresponding to the index 4 is 1, the index 3 and the index 4 correspond to the same downlink time slot, and the conflict is caused; if the corresponding value of the index 4 is 2, the position of the first time domain unit is moved backwards by two time slots, the original U slot is changed into the D slot, and the D slot is prevented from being occupied by other data, so that the network equipment can send the data to the terminal equipment by using the first time domain unit.

Index	0	1	2	3	4
						Time slot configuration	D	D	D	U	U
Candidate value	0	0	0	2	2

In one possible implementation manner, the network device determines the position of the first time domain resource unit according to the configuration period duration of the configuration resource, judges whether the position meets the transmission requirement, and does not modify if yes; if not, the bias parameters are considered for modification, so that the modified position meets the transmission requirement.

Specifically, the position meeting the transmission requirement means that the position corresponds to an available D slot or S slot.

By way of example and not limitation, the location of the first time domain resource unit determined from the configuration period duration of the configuration resource satisfies:

(numberOfSlotsPerFrame×m+n)＝int(N×periodicity×numberOfSlotsPerFrame/i+numberOfSlotsPerFrame×SFNstart time+slotstart time)modulo(k)，

wherein m represents a frame number of a wireless system frame where a first time domain resource unit is located, N represents a time slot number of the first time domain resource unit, int represents a rounding operation, modolu represents a modulo operation, N is an integer greater than or equal to 0, periodic represents a configuration period duration of a configuration resource, numberOfSlotsPerFrame represents a time slot number contained in the wireless system frame, i represents a time domain length of the wireless system frame, SFNstart time represents a starting wireless frame number of the configuration resource, slotstart time represents a starting time slot number of the configuration resource, and k represents a time slot number contained in a wireless system superframe.

Specifically, the location of the first time domain resource unit may be represented as the nth slot in a wireless system frame having a frame number m. In the method, N may represent that the network device transmits data to the terminal device for the nth time after the initialization, N equals to 0 and represents a location of initialization of the configuration resource, where the location is represented by the SFNstart time and the slotstart time, and by way of example, the SFNstart time may refer to a radio frame number of initial transmission of the PDSCH, and the slotstart time may refer to a slot number of initial transmission of the PDSCH. number ofslotsperframe indicates the number of slots included in the radio system frame, i indicates the time domain length of the radio system frame, k indicates the number of slots included in the radio system superframe, and illustratively, the value of i may be 10, the value of k may be 20480, and the value of number ofslotsperframe may be 20.

Taking 60FPS as an example, assume sfnsttart time=0, slotstart time=0:

when n=0, int (0+0×50/3×20/10) =int (0) =0, (0) module (1024×20) =0;

when n=1, int (0+1×50/3×20/10) =int (100/3) =34, (34) module (1024×20) =34;

when n=2, int (0+2×50/3×20/10) =int (100/3) =67, (67) module (1024×20) =67;

when n=3, int (0+3×50/3×20/10) =int (100) =100, (100) module (1024×20) =100;

When n=2, the position of the first time domain resource unit corresponds to the U slot, so that the position of the first time domain resource unit needs to be modified again, and the position of the first time domain resource unit may be modified according to the offset parameter determined in the above method.

In one possible implementation, the network device determines the location of the first time domain resource unit directly from the bias parameter and the configuration period duration of the configuration resource.

By way of example and not limitation, the location of the first time domain resource unit satisfies:

(numberOfSlotsPerFrame×m+n)＝[int(N×periodicity×numberOfSlotsPerFrame/i+numberOfSlotsPerFrame×SFNstart time+slotstart time)+offset]modulo(k)，

the offset represents an offset parameter with granularity of the time slot, and other parameters are detailed in the above description and are not repeated here.

Taking 60FPS as an example, assume sfnsttart time=0, slotstart time=0:

when n=0, int (0+0×50/3×20/10) =int (0) =0, offset=offset (0) =0, (0+0) module (1024×20) =0;

when n=1, int (0+1×50/3×20/10) =int (100/3) =34, offset=offset (4) =0, (34+0) module (1024×20) =34;

when n=2, int (0+2×50/3×20/10) =int (100/3) =67, offset=offset (7) =1, (67+1) module (1024×20) =68;

when n=3, int (0+3×50/3×20/10) =int (100) =100, offset=offset (0) =0, (100+0) module (1024×20) =100;

Therefore, SPS occalasion exists on 0slot,34slot,68slot and 100slot, and downlink data arrives at network equipment on 0slot, 100/3slot, 200/3slot and 100slot, so that SPS resources can be just matched with service periods and are all on D slot.

Further, if there is an S slot in the TDD slot configuration, the position of the first time domain resource unit may be a usable D slot, or may be a downlink symbol usable in the S slot or a flexible symbol configured to be used for transmitting downlink data.

For example, when the index corresponds to the S slot, and if the starting symbol of the S slot for transmitting data corresponds to the downlink symbol or is configured as a flexible symbol for transmitting downlink data, the position of the first time domain resource unit may correspond to the S slot, that is, the offset candidate value corresponding to the S slot is 0, specifically, the starting symbol of the S slot for transmitting data may be obtained from the starting symbol and the length SLIV domain; if the initial symbol of the data transmitted in the S slot corresponds to an uplink symbol or is configured as a flexible symbol for transmitting uplink data, the position of the first time domain resource unit may correspond to D slot closest to the S slot, that is, the offset candidate value corresponding to the S slot is not 0, or may correspond to a downlink symbol in the S slot or is configured as a flexible symbol for transmitting downlink data, that is, the offset candidate value corresponding to the S slot is 0.

Optionally, S440, the terminal device receives data from the network device at the location of the first time domain resource unit. The method for determining the location of the first time domain resource unit by the terminal device is similar to that of the network device, and will not be described herein.

Based on the method, the configuration resource can be allocated or appointed once through the PDCCH, and then the same time-frequency resource can be periodically reused for uplink transmission, so that the expenditure of signaling is effectively reduced.

The method and the device can calculate the position of the first time domain resource unit by using the period duration of the service, reduce time delay, avoid the influence of transmission times and improve the communication quality.

In addition, in the embodiment of the application, the first time domain resource unit can meet the uplink transmission requirement of the communication equipment, and the downlink transmission resource is avoided being determined when uplink data transmission is needed, so that the data is ensured not to be missed, and the reliability of data transmission is improved. The terminal equipment and the network equipment determine the position of the first time domain resource unit through the configuration period of the configuration resource, which is favorable for keeping synchronization and improving the communication quality.

Fig. 5 is an interactive flowchart of a communication method 500 provided in an embodiment of the present application. In fig. 5, the network device and the terminal device are taken as an example to illustrate the method according to the execution subject of the interactive instruction, but the application is not limited to the execution subject of the interactive instruction. For example, the network device in fig. 5 may also be a chip, a system-on-a-chip, or a processor that supports the network device to implement the method, or may be a logic module or software that can implement all or part of the functions of the network device; the terminal device in fig. 5 may also be a chip, a system-on-chip, or a processor supporting the terminal device to implement the method, or may be a logic module or software capable of implementing all or part of the functions of the terminal device.

S510, the terminal equipment obtains the configuration period duration of the configuration resource.

The period duration of the configuration resource may be determined according to the period duration of the service, and illustratively, the period duration of the service is acquired by the terminal device, where the period duration of the configuration resource is equal to the period duration of the service, specifically, the period duration of the service is acquired by the terminal device through internal interlayer interaction, which is used as an example and not a limitation, and the period duration of the service is acquired from the application layer by the terminal device.

Optionally, S520, the network device obtains a configuration period duration of the configuration resource, where the configuration period duration may be sent to the network device by the terminal device.

Optionally, S530, the network device configures configuration resources for transmitting the service data.

Specifically, the network device configures relevant parameters of the configuration resource through radio resource control (radio resource control, RRC) signaling, where the relevant parameters of the configuration resource include an unlicensed scheduling identifier, a configuration period duration of the configuration resource, a time domain frequency domain resource of the configuration resource, and harq-process, and if the configuration resource is a CG resource of Type1, the RRC signaling further configures the time domain frequency domain resource.

Illustratively, the unlicensed scheduling identity may be a CS-RNTI.

By way of example and not limitation, the configuration resource may be CG resource for the network device to receive data from the terminal device or for the terminal device to send data to the network device, where the configuration resource is exemplified by CG resource, where periodicity represents a configured period duration and FPS represents a configured frame rate:

S540, the terminal equipment sends data on a first time domain resource unit, the first time domain resource unit is contained in the configuration resource, the position of the first time domain resource unit is determined by a bias parameter and the configuration period duration of the configuration resource, and the value of the bias parameter is related to time division duplex TDD time slot configuration.

The terminal equipment determines the value of the bias parameter, wherein the value of the bias parameter is related to the Time Division Duplex (TDD) time slot configuration, specifically, the TDD time slot configuration corresponds to one or more candidate values of the bias parameter, and the value of the bias parameter is one of the candidate values.

By way of example and not limitation, the configured resource is CG resource of Type1, and the time slot of TDD in one period is configured as DDUUU, where D is a downlink time slot and U is an uplink time slot.

The network device determines an index value according to the configuration of the configuration resource, wherein the index value (slot-index) meets the following conditions: slot-index=int (n×periodic/numberofsymbolsperslot+r×numberofslotsperframe+d+s) modu (R),

Where r represents the number of slots included in one period of slot configuration, numberofsymbolsper represents the number of symbols included in a slot, and R, D and S are parameters configured through radio resource control RRC signaling.

Specifically, numberOfSymbolsPerSlot is a parameter in a wireless system, and may have a value of 14, for example; r, D and S are parameters configured by radio resource control RRC signaling, and by way of example R may be timereference sfn and D may be timeDomainOffset. The remaining parameters are referred to the description in the SPS resource, and are not described herein.

In this embodiment of the present application, the network device may activate the CG resource of the corresponding Type1 through RRC signaling.

Taking 60FPS as an example, let d=0, s=0, r=0, and periodicity take the symbol granularity as granularity:

when n=0, slot-index=int (0+0+0) moduu (5) =0;

when n=1, slot-index=int (0+0+100/3) modu (5) =4;

when n=2, slot-index=int (0+0+200/3) modu (5) =2;

when n=3, slot-index=int (0+0+100) moduu (5) =0;

Index	0	1	2	3	4
						Time slot configuration	D	D	U	D	D
Candidate value	2	1	0	4	3

If the calculated slot-index value is 1, the offset parameter value is 1, namely the position of the first time domain unit is moved backwards by one time slot, and the original Dslot is changed into Usilot, so that the network equipment receives the data sent by the terminal equipment in the first time domain unit.

In one possible implementation, the available time slots refer to the time slots which are closest to and not occupied and meet the data transmission requirement, and the network device can obtain a first list shown in the following table according to the time slot configuration, wherein the first list considers the situation that multiple groups of data transmission exist on configuration resources simultaneously when determining candidate values, if the value corresponding to the index 1 is 1, the index 0 and the index 1 correspond to the same uplink time slot, and the conflict is caused.

Index	0	1	2	3	4
						Time slot configuration	D	D	U	D	D
Candidate value	2	6	0	4	8

If the calculated slot-index value is 1, the offset parameter value is 6, namely the position of the first time domain unit is moved backwards by six time slots, the original Dslot is changed into a Uslot, and the Uslot is prevented from being occupied by other data, so that the network equipment can receive the data sent by the terminal equipment in the first time domain unit.

In the case of CG resources of Type1, the bias parameter may be at symbol granularity, with the bias parameter being equal to the product of the selected candidate value and the number of symbols per slot.

By way of example and not limitation, the configured resource is CG resource of Type2, and the time slot of TDD in one period is configured as DDUUU, where D is a downlink time slot and U is an uplink time slot.

Taking 60FPS as an example, assume sfnsttart time=0, slotstart time=0:

when n=0, slot-index=int (0+0+0) moduu (5) =0;

when n=1, slot-index=int (0+0+100/3) modu (5) =4;

when n=2, slot-index=int (0+0+200/3) modu (5) =2;

when n=3, slot-index=int (0+0+100) moduu (5) =0;

If the calculated slot-index value is 1, the offset parameter value is 1, namely the position of the first time domain unit is moved backwards by one time slot, and the original D slot is changed into U slot, so that the network equipment receives the data sent by the terminal equipment in the first time domain unit.

Index	0	1	2	3	4
						Time slot configuration	D	D	U	D	D
Candidate value	2	1	0	4	3

Index	0	1	2	3	4
						Time slot configuration	D	D	U	D	D
Candidate value	2	6	0	4	8

In the embodiment of the present application, for convenience of explanation, the bias parameter is described as moving backward, and the specific moving mode is not limited in the application, and may be a previous moving mode, or may even be a moving mode according to other preset rules, where the specific moving mode is related to the determination mode of the candidate value in the first list.

In one possible implementation manner, the terminal device determines the position of the first time domain resource unit according to the configuration period duration of the configuration resource, judges whether the position meets the transmission requirement, and does not modify if yes; if not, the bias parameters are considered for modification, so that the modified position meets the transmission requirement.

Specifically, the location meeting the transmission requirement means that the location corresponds to an available U slot.

By way of example and not limitation, the configuration resource is CG resource of Type1, the location of the first time domain resource unit satisfies: (mXnumber OfSlotsPerframe Xnumber OfSymbipsPerslot) + (nXnumber OfSymbipsPerslot) +p=int (S+N×periodic+R X number OfSlotsPerframe Xnumber OfSymbipsPerslot+D X number OfSymbipsPerslot) module (K).

Wherein m represents a frame number of a radio system frame where the first time domain resource unit is located, n represents a time slot number where the first time domain resource unit is located, p represents a symbol number of the first time domain resource unit, K represents a number of symbols included in a radio system superframe, numberofsymbol per slot represents a number of symbols included in a time slot, and R, D and S are parameters configured through radio resource control RRC signaling.

Specifically, the position of the first time domain resource unit may be represented as a p-th symbol in a slot with a slot number n in a wireless system frame with a frame number m. In the above method, the numberofsymbol Perslot and the K are parameters in the wireless system, and by way of example, the numberofsymbol Perslot may have a value of 14 and the K may have a value of 286720; r, D and S are parameters configured by radio resource control RRC signaling, and by way of example R may be timereference sfn and D may be timeDomainOffset. The remaining parameters are referred to the description in the SPS resource, and are not described herein.

Taking 60FPS (period of 50/3 ms) as an example, the subcarrier spacing is 30kHz, and assuming r=0, d=0, s=0, the slot is configured as DDUDD, and the periodicity is granularity of symbols, i.e. periodicity=50/3×20/10×14=1400/3 sym.

When n=0, int (0+0×50/3×20/10×14) =int (0) =0, (0) module (1024×20×14) =0 sym (0 slot);

when n=1, int (0+1×50/3×20/10×14) =int (1400/3) =467, (467) module (1024×20×14) =467 sym (34 slot);

when n=2, int (0+2×50/3×20/10×14) =int (2800/3) =934, (934) module (1024×20×14) =934 sym (67 slot);

when n=3, int (0+3×50/3×20/10×14) =int (1400) =1400, (1400) module (1024×20×14) =1400 sym (100 slot);

since the timeslot is configured as DDUDD, when n=0, 1, 3, the position of the first time domain resource unit corresponds to Dslot, so that the position of the first time domain resource unit needs to be modified again so that the position of the first time domain resource unit corresponds to the nearest Uslot, and the position of the first time domain resource unit may be modified according to the offset parameter determined in the above method. After modification, CG occalasion exists on 2 slots, 37 slots, 67 slots and 102 slots, and uplink data arrives on 0slot, 100/3slot, 200/3slot and 100slot, so that CG resources can be just matched with service periods and are also all stored on U slots.

Further, if an Sslot exists in the TDD timeslot configuration, the position of the first time domain resource unit may be a usable U slot, or may be a downlink symbol usable in the Sslot or a flexible symbol configured to be used for transmitting downlink data.

For example, when the above index corresponds to Sslot, and the initial symbol of the Sslot for transmitting data corresponds to an uplink symbol or is configured as a flexible symbol for transmitting uplink data, the position of the first time domain resource unit may correspond to the Sslot, that is, the offset candidate value corresponding to the Sslot is 0, specifically, the initial symbol of the Sslot for transmitting data may be obtained from the initial symbol and the length SLIV domain; if the initial symbol of the Sslot sent data corresponds to a downlink symbol or is configured as a flexible symbol for transmitting downlink data, the position of the first time domain resource unit may correspond to a position of the Sslot closest to the Sslot, that is, the offset candidate value corresponding to the Sslot is not 0, or may correspond to an uplink symbol in the Sslot or is configured as a flexible symbol for transmitting uplink data, that is, the offset candidate value corresponding to the Sslot is 0.

By way of example and not limitation, the configuration resource is CG resource of Type2, the location of the first time domain resource unit satisfies: (mXnumber OfSlotsPerframe Xnumber OfSymbssPerSlot) + (nXnumber OfSymbsPerSlot) +p=int (NXperiodic+symbol start time+SFNstart time Xnumber OfSlotsPerframe Xnumber OfSymbsPerslot+slot start time Xnumber OfSymbsPerslot) module (K),

Wherein m represents a frame number of a wireless system frame where a first time domain resource unit is located, N represents a time slot number where the first time domain resource unit is located, p represents a symbol number of the first time domain resource unit, int represents a rounding operation, modolu represents a modulo operation, N is an integer greater than or equal to 0, and periodicity represents a configuration period duration of a configuration resource, numberOfSlotsPerFrame represents a number of time slots contained in the wireless system frame, numberofsymbolt represents a number of symbols contained in the time slots, SFNstart time represents a starting wireless frame number of the configuration resource, slotstart time represents a starting time slot number of the configuration resource, and K represents a number of symbols contained in a wireless system superframe.

Specifically, the position of the first time domain resource unit may be represented as a p-th symbol in a slot with a slot number n in a wireless system frame with a frame number m. In the above method, the numberofsymbol period and K are parameters in the wireless system, and by way of example, the numberofsymbol period may have a value of 14 and the K may have a value of 286720.

Taking 60FPS as an example, assume sfnsttart time=0, slotstart time=0:

when n=0, int (0+0×50/3×20/10) =int (0) =0, (0) module (1024×20) =0;

When n=1, int (0+1×50/3×20/10) =int (100/3) =34, (34) module (1024×20) =34;

when n=2, int (0+2×50/3×20/10) =int (66.67) =67, (67) module (1024×20) =67;

when n=3, int (0+3×50/3×20/10) =int (100) =100, (100) module (1024×20) =100;

By way of example and not limitation, if the configuration resource is CG resource of Type1, the location of the first time domain resource unit satisfies:

(m×numberOfSlotsPerFrame×numberOfSymbolsPerSlot)+(n×numberOfSymbolsPerSlot)+p＝[int(S+N×periodicity+R×numberOfSlotsPerFrame×numberOfSymbolsPerSlot+D×numberOfSymbolsPerSlot)+offset]modulo(K)

The offset represents an offset parameter of the symbol of the slot, and the remaining parameters are referred to the description in the SPS resource, which is not described herein.

When n=0, int (0+0×50/3×20/10×14) =int (0) =0, slot-index=0, offset=offset (0) =2×14=28, (0+28) module (1024×20×14) =28 sym (2 slot);

when n=1, int (0+1×50/3×20/10×14) =int (1400/3) =467, slot-index=int (1400/3/14) modu10=4, offset=offset (4) =3, (467+3×14) modo (1024×20×14) =470 sym (37 slot);

when n=2, int (0+2×50/3×20/10×14) =int (2800/3) =934, slot-index=int (2800/3/14) modu10=7, offset=offset (7) =0, (934+0×14) modo (1024×20×14) =934 sym (67 slot);

when n=3, int (0+3×50/3×20/10×14) =int (1400) =1400, offset=offset (0) =2, (100+0) module (1400+2×14) module (1024×20×14) =1428 sym (102 slot);

therefore, CG occasing exists on 2 slots, 37 slots, 67 slots and 102 slots, and uplink data arrives on 0slot, 100/3slot, 200/3slot and 100slot, so that CG resources can be just matched with service periods and are also all stored on U slots.

By way of example and not limitation, if the configuration resource is CG resource of Type2, the location of the first time domain resource unit satisfies:

(m×numberOfSlotsPerFrame×numberOfSymbolsPerSlot)+(n×numberOfSymbolsPerSlot)+p＝[int(SFNstart time×numberOfSlotsPerFrame×numberOfSymbolsPerSlot+slotstart time×numberOfSymbolsPerSlot+symbolstart time+N×periodicity)+offset]modulo(K)，

Taking 60FPS (period of 50/3 ms) as an example with a subcarrier spacing of 30kHz, the slot is configured as DDUDD assuming SFNstart time=0, slotstart time=0.

When n=0, int (0+0×50/3×20/10) =int (0) =0, offset=offset (0) =2, (0+2) module (1024×20) =2;

When n=1, int (0+1×50/3×20/10) =int (100/3) =34, offset=offset (4) =3, (34+3) module (1024×20) =37;

when n=2, int (0+2×50/3×20/10) =int (100/3) =67, offset=offset (7) =0, (67+0) module (1024×20) =67;

when n=3, int (0+3×50/3×20/10) =int (100) =100, offset=offset (0) =2, (100+2) module (1024×20) =102;

Further, if an Sslot exists in the TDD slot configuration, the position of the first time domain resource unit may be a usable U slot, or may be an uplink symbol usable in the Sslot or a flexible symbol configured to be used for transmitting uplink data.

For example, when the above index corresponds to Sslot, and the initial symbol of the Sslot for transmitting data corresponds to an uplink symbol or is configured as a flexible symbol for transmitting uplink data, the position of the first time domain resource unit may correspond to the Sslot, that is, the offset candidate value corresponding to the Sslot is 0, specifically, the initial symbol of the Sslot for transmitting data may be obtained from the symbol start time; if the initial symbol of the Sslot sent data corresponds to a downlink symbol or is configured as a flexible symbol for transmitting downlink data, the position of the first time domain resource unit may correspond to a position of the Sslot closest to the Sslot, that is, the offset candidate value corresponding to the Sslot is not 0, or may correspond to an uplink symbol in the Sslot or is configured as a flexible symbol for transmitting uplink data, that is, the offset candidate value corresponding to the Sslot is 0.

Optionally, S550, the network device receives data from the terminal device at the location of the first time domain resource unit. The network device determines that the location of the first time domain resource unit is similar to the terminal device, which is not described herein.

In the embodiment of the present application, the configuration period duration of the configuration resource refers to an ideal parameter when the bias occurs, and in an actual process, due to the existence of the bias parameter, data transmission is not periodic, but a certain deviation occurs. In this embodiment of the present application, the network device may activate the CG resource of the corresponding Type1 through RRC signaling, activate the CG resource of the corresponding Type2 through PDCCH, and indicate the allocated frequency domain resource.

Based on the method, the configuration resource can be allocated or appointed once through RRC or PDCCH, and then the same time-frequency resource can be periodically reused for uplink transmission, so that the expenditure of signaling is effectively reduced.

Based on the method, the first time domain resource unit can meet the uplink transmission requirement of the communication equipment, and the downlink transmission resource is avoided being determined when uplink data transmission is needed, so that the data is ensured not to be missed, and the reliability of data transmission is improved.

In order to solve the problem that an error exists between the data volume reported by the buffer status report and the actual data volume, the application also provides a method for reporting the buffer status report. When sending an uplink data establishment quality of service (quality of service, qoS) flow, the core network device adds first information in a QoS rule (QoS rule), where the first information is used to indicate that data carried by the QoS flow uses a fine-grained buffer status report (buffer state reporting, BSR) format when performing BSR. The access network device performs QoS control according to QoS rules, specifically, the access network device maps uplink data in QoS flows containing first information onto specific radio data bearers (data radio bearer, DRBs), and the data on the DRBs reports the buffer status using long buffer status report format (long BSR format). When the data arrives at the terminal to buffer and trigger the BSR, the terminal reports the buffer status by using the long BSR format. By the method, errors between the reported data quantity and the actual data quantity of the BSR can be reduced, so that transmission resources are saved, and the system capacity is improved.

The sequence of each step in the above-mentioned flowchart is determined according to the inherent logic of the method, and the sequence number shown in the above-mentioned flowchart is only an example, and does not limit the sequence of the steps in the present application.
