Description

Resource allocation method and device and related equipment

Technical Field

The present disclosure relates to the field of communications technologies, and in particular, to a method and an apparatus for resource allocation, and related devices.

Background

Currently, mobile communication systems are required to provide services for more and more types of services, for example, enhanced mobile broadband (enhanced mobile broadband, eMBB) services, high reliability low latency communication (URLLC) services, and augmented reality (XR) services. Wherein, different types of services have different requirements on the network, and the characteristics of the services can be different. For example, XR services typically transmit large amounts of data (e.g., high definition video information is required to be transmitted), and the transmitted data has a certain periodicity (e.g., video typically has a certain frame rate). XR services have high requirements for both data transmission rate and data transmission delay.

To reduce signaling overhead, for uplink traffic, the 3GPP standards introduce an Uplink (UL) Configured Grant (CG) transmission mechanism for uplink traffic with periodic features. The configuration authorization flow includes pre-configuring scheduling resources for the periodic uplink data transmission service, and when the data of the terminal device needs to be transmitted in uplink data, the CG configured resources can be directly used for uplink data transmission. Similarly, for downlink traffic, the 3GPP standards introduced a semi-persistent scheduling (SPS) mechanism for downlink traffic with periodic features. The scheduling mechanism comprises pre-configuring scheduling resources for the periodic downlink data transmission service, so that the terminal equipment can periodically receive the corresponding physical downlink shared channel (physical downlink shared channel, PDSCH), and the base station does not need to schedule the resources of the PDSCH through a physical downlink control channel (physical downlink control channel, PDCCH) before transmitting downlink data each time, thereby reducing signaling overhead of downlink data transmission.

The mechanism of SPS/CG is to pre-configure transmission resources for periodic traffic so that these same resources are used for transmission whenever data arrives. Although the data transmitted by XR traffic is periodic in time, the amount of data per period is not necessarily the same, and even the dynamic range of the amount of data per period may be large. For example, in actually transmitting video frames, not every frame needs to transmit a complete image, but only the amount of change from the previous frame may be transmitted, thereby improving system performance. Thus, although XR traffic transmissions have periodicity, the size of the data amount per data period may depend on how fast the picture changes. That is, the data amount per data period may range from 0bit to 1.9962 ×10 ⁸ bit to bit variations. However, SPS/CG scheduling resources are relatively fixedAnd definitely, the service with larger dynamic range of the data volume cannot be flexibly adapted.

Disclosure of Invention

The embodiment of the application provides a resource allocation method, a device and related equipment, wherein the method can realize flexible CG/SPS time-frequency domain resource allocation and scheduling, and is beneficial to flexibly adapting to services with larger data volume dynamic range.

In a first aspect, an embodiment of the present application provides a resource allocation method, which may be applied to an uplink configuration authorization scenario. The method is performed by the network device, may be performed by a component of the network device (e.g., a processor, a chip, or a system-on-a-chip, etc.), and may be implemented by a logic module or software that is capable of implementing all or part of the functions of the network device. The network equipment receives the data quantity information from the terminal equipment, determines a data quantity grading result and a reference resource according to the data quantity information, and sends the data quantity grading result and the reference resource to the terminal equipment. The data quantity grading result is used for determining a gear to which the data quantity belongs in each resource allocation period under the configuration authorization CG mechanism, and the reference resource is used for determining a resource corresponding to the gear to which the data quantity belongs in each resource allocation period.

By the method, in an uplink configuration authorization scene, the network equipment receives data volume information from the terminal equipment, and information alignment between the terminal equipment and the network equipment is facilitated. The network equipment carries out the grading processing on the uplink data volume and determines the actual resources required by the data volume transmission in each resource allocation period, thereby realizing flexible CG time-frequency domain resource allocation and scheduling and being beneficial to adapting to the service with larger dynamic range of the data volume.

In one possible design, the network device determines, from the data volume information, a maximum data volume in the data volume information as a reference data volume. By the method, the network equipment selects the maximum data volume as the reference data volume, which is beneficial to guaranteeing the integrity of service transmission.

In one possible design, the result of the shift of the data quantity includes one or more of the number of shifts or a reference data quantity or a shift range to which the data quantity belongs. The number of steps is used to represent the number of steps of the data amount, and the steps to which the data amount belongs can be represented by step vectors. For example, the network device may preset or preconfigure a number of steps, which is used by the network device for any traffic of data volume, and determine the result of the step of the data volume in combination with the reference data volume, in which case the result of the step of the data volume is in particular a step vector, i.e. the step to which the data volume belongs. By the method, the network equipment can directly and specifically indicate the gear to which the data quantity belongs to the terminal equipment, so that the terminal equipment can directly determine the gear to which the data quantity belongs, and the operation flow is simplified. For another example, the network device may determine the number of steps or the step vector based on the data amount information if the network device does not preset or preconfigure a number of steps. By the method, the network equipment can directly indicate the number of the steps or the step vector to the terminal equipment, namely, in the case that the step result of the data quantity is the step number, the data quantity step can be indicated by using less expenditure for the network side, and the terminal side further determines the step to which the data quantity belongs by combining the data quantity information and the step number for the terminal side; or the network device can directly indicate the gear to which the data quantity belongs to the terminal device, which is beneficial to the terminal device to directly determine the gear to which the data quantity belongs and simplifies the operation flow.

In one possible design, the network device determines, according to the gear and the reference resource to which the data amount in each resource allocation period belongs, a resource corresponding to the data amount in each resource allocation period, where the resource corresponding to the data amount in each resource allocation period is used for data transmission between the network device and the terminal device in each resource allocation period. By the method, the network equipment can realize flexible CG time-frequency domain resource allocation and scheduling based on data volume grading, and is beneficial to adapting to services with larger data volume dynamic range.

In one possible design, the resource allocation period is a first allocation period or a second allocation period, the first allocation period is a CG period in which the configurable CG period and the data arrival time satisfy a first relationship or a second relationship, the second allocation period is determined according to the first allocation period and the data arrival time, and the second allocation period is matched with the data arrival time. By the method, the network equipment performs the grading of the data volume, and is suitable for not only the scene with uncorrected CG period, but also the scene with corrected CG period, thereby being beneficial to realizing the matching of CG period and data arrival time and adapting to the service with larger dynamic range of the data volume.

In one possible design, the first configuration period in which the configurable CG period satisfies a first relationship with the data arrival time is a minimum CG period in the configurable CG period that is greater than the data arrival time when one or more CG periods exist in the configurable CG period that is greater than the data arrival time. The first configuration period in which the configurable CG period and the data arrival time satisfy the second relationship is a maximum CG period in the configurable CG period when the configurable CG periods are each smaller than the data arrival time.

In one possible design, the result of the data amount stepping is indicated by radio resource control, RRC, signaling. By the method, DCI configuration overhead is not increased.

In one possible design, the reference resources are indicated by radio resource control, RRC, signaling or by DCI. By this method, when the reference resource is indicated by RRC, DCI configuration overhead is not increased. When the reference resource is indicated by DCI, in the CG type2 configuration procedure, there is no need to modify the existing CG configuration procedure.

In a second aspect, an embodiment of the present application provides a resource allocation method, which is applied to an uplink configuration authorization scenario. The method is executed by the terminal device, may be executed by a component (such as a processor, a chip, or a chip system) of the terminal device, and may be implemented by a logic module or software capable of implementing all or part of the functions of the terminal device. The terminal equipment sends data quantity information to the network equipment; the terminal equipment receives the data quantity grading result from the network equipment and the reference resource, determines the gear to which the data quantity belongs in each resource allocation period under the configuration authorization CG mechanism according to the data quantity grading result, and determines the resource corresponding to the gear to which the data quantity belongs in each resource allocation period according to the reference resource. According to the method, in an uplink configuration authorization scene, the terminal equipment sends data quantity information to the network equipment, so that the network equipment can determine a grading result of the data quantity and a reference resource according to the data information, and information alignment between the terminal equipment and the network equipment is realized. The terminal equipment receives the result of the up-stream data volume grading processing of the network equipment, and determines the actual resources required by the data volume transmission in each resource allocation period, thereby realizing flexible CG time-frequency domain resource allocation and scheduling, and being beneficial to adapting to the service with larger dynamic range of the data volume.

For example, the terminal equipment directly receives the gear step vector sent by the network equipment, and by the method, the terminal equipment directly receives the gear step to which the data quantity specifically indicated by the network equipment belongs, thereby being beneficial to directly determining the gear step to which the data quantity belongs by the terminal equipment and simplifying the operation flow. For another example, the terminal device receives the number of steps sent by the network device, that is, in this implementation, the result of the step of the data amount is specifically the number of steps, and the terminal device needs to further determine the step to which the data amount belongs by combining the data amount information and the number of steps.

In one possible design, the terminal device performs data transmission with the network device in each resource allocation period according to the resource corresponding to the gear to which the data amount in each resource allocation period belongs.

The network device determines a reference resource according to the data volume information and sends the reference resource to the terminal device. The reference resource is used for determining the resource corresponding to the gear to which the data quantity belongs in each resource allocation period. By the method, in an uplink configuration authorization scene, the terminal equipment can carry out the grading processing on the uplink data quantity by itself and report the grading processing result to the network equipment, thereby being beneficial to information alignment between the terminal equipment and the network equipment. Based on the data quantity grading result, the network device determines the actual resources required by data quantity transmission in each resource allocation period, thereby realizing flexible CG time-frequency domain resource allocation and scheduling, and being beneficial to adapting to the service with larger data quantity dynamic range.

Detailed Description

In a wireless communication system including communication devices, communication devices can perform wireless communication by using air interface resources. The communication device may include a network device and a terminal device, and the network device may also be referred to as a network side device. The air interface resources may include at least one of time domain resources, frequency domain resources, code resources, and space resources. In the embodiments of the present application, at least one may also be described as one or more, and a plurality may be two, three, four or more, which is not limited in this application.

In the embodiment of the present application, "/" may indicate that the associated object is an "or" relationship, for example, a/B may indicate a or B; "and/or" may be used to describe that there are three relationships associated with an object, e.g., a and/or B, which may represent: there are three cases, a alone, a and B together, and B alone, wherein a, B may be singular or plural. In order to facilitate description of the technical solutions of the embodiments of the present application, in the embodiments of the present application, the words "first", "second", etc. may be used to distinguish between technical features that are the same or similar in function. The terms "first," "second," and the like do not necessarily denote any order of quantity or order of execution, nor do the terms "first," "second," and the like. In this application embodiment, the terms "exemplary" or "such as" and the like are used to denote examples, illustrations, or descriptions, and any embodiment or design described as "exemplary" or "such as" should not be construed as preferred or advantageous over other embodiments or designs. The use of the word "exemplary" or "such as" is intended to present the relevant concepts in a concrete fashion to facilitate understanding.

The technical solutions in the embodiments of the present application will be described below with reference to the drawings in the embodiments of the present application.

Currently, mobile communication systems are required to provide services for more and more types of services, for example, enhanced mobile broadband (enhanced mobile broadband, eMBB) services, high reliability low latency communication (URLLC) services, and augmented reality (XR) services. Wherein, different types of services have different requirements on the network, and the characteristics of the services can be different. Common XR services include Virtual Reality (VR) and augmented reality (augmented reality, AR).

In a first aspect, data transmission for XR and like services has a certain periodicity (e.g. video typically has a certain frame rate). Under the conventional Dynamic Grant (DG) transmission mechanism, each time a terminal device needs to perform uplink data transmission, the following steps need to be repeatedly performed: a waiting Base Station (BS) transmits downlink control information (downlink control information format, dcifermat 0) of format 0 through a physical downlink control channel (physical downlink control channel, PDCCH), and indicates information such as physical uplink shared channel (physical uplinksharedchannel, PUSCH) resources, coding modulation mode, and the like; and modulating the codes according to the indicated code modulation information, and transmitting uplink data by using the scheduled PUSCH resource. Similarly, in the downlink data receiving process, the terminal device needs to repeatedly execute the following steps: and monitoring and blind detection are carried out on the PDCCH, so that DCI (DCI format 1) of the format1 carried in the DCI is solved. When the scheduling information belonging to the own is detected, the data information belonging to the own is received and demodulated according to the instruction of the scheduling information (including physical downlink shared channel (physical downlink shared channel, PDSCH) resources, code modulation scheme, and the like). However, in both cases, there is a large amount of signaling interaction, which may result in reduced spectral efficiency and may also introduce additional delay and power consumption.

To reduce signaling overhead, for uplink traffic, the 3GPP standards introduce an Uplink (UL) Configured Grant (CG) transmission mechanism for uplink traffic with periodic features. The configuration authorization flow includes pre-configuring scheduling resources for the periodic uplink data transmission service, and when the data of the terminal device needs to be transmitted in uplink data, the CG configured resources can be directly used for uplink data transmission. Similarly, for downlink traffic, the 3GPP standards introduced a semi-persistent scheduling (SPS) mechanism for downlink traffic with periodic features. The scheduling mechanism comprises the steps that scheduling resources are pre-configured for the periodical downlink data transmission service, so that the terminal equipment can periodically receive the corresponding PDSCH, and the wireless network equipment does not need to schedule the resources of the PDSCH through a PDCCH before transmitting the downlink data each time, so that the signaling overhead of the downlink data transmission is reduced.

However, there may be a problem of mismatch between the data period of the uplink/downlink traffic and the configurable CG/SPS period. Therefore, if the data corresponding to a certain data period arrives but no corresponding SPS/CG scheduled resource exists, the data cannot be transmitted in time, and the data needs to wait for the resource scheduled in the next SPS/CG period to be transmitted, thereby increasing the delay of data transmission.

In order to solve the problem of the first aspect, an embodiment of the present application provides a resource allocation method, which determines a period adjustment parameter, and corrects an SPS/CG period by the period adjustment parameter, so as to be beneficial to matching the SPS/CG period with a data period.

In the second aspect, the amount of data transmitted by XR service is generally large (e.g. high definition video information needs to be transmitted), and XR service has high requirements on data transmission rate and data transmission delay. For example, table 1 shows the demand parameters of a typical XR service.

Table 1: demand parameter table for typical XR service

As can be seen from Table 1, the AR/VR services all have high latency requirements (in the order of milliseconds) and high data rate requirements (in the order of Mbps). Correspondingly, more transmission resources and lower scheduling and transmission delay are needed for providing services such as AR/VR.

According to the first aspect described above, the mechanism of SPS/CG is to pre-configure transmission resources for periodic traffic such that these same resources are used for transmission whenever data arrives. Although the data transmitted by XR traffic is periodic in time, the amount of data per period is not necessarily the same, and even the dynamic range of the amount of data per period may be large. For example, if a super-high definition video with a resolution of 3840×2166 is displayed by using 256-level three primary colors (RGB), a frame of complete image corresponds to 3840×2166×3×log data ₂ 256＝1.9962×10 ⁸ bit. If the frame rate of a video frame is 60 Frames Per Second (FPS), there will be one frame of image to be transmitted every 16.67 ms. However, in actual transmission, not every frame needs to transmit a complete image, but only the amount of change from the previous frame may be transmitted, thereby improving system performance. Thus, although XR traffic transmission has periodicity (data period T _p =16.67 ms), the data size per data period may depend on how fast the picture changes. That is, the data amount per data period may range from 0bit to 1.9962 ×10 ⁸ bit to bit variations. However, SPS/CG scheduling resources are relatively fixed, and cannot flexibly adapt to services with a large dynamic range of data size.

In order to solve the problem of the second aspect, the embodiment of the application provides another resource allocation method, which allocates different SPS/CG resources for different data volumes, and is beneficial to flexibly adapting to services with larger dynamic range of the data volumes.

It should be noted that, the resource allocation method provided in the embodiment of the present application may be suitable for a scenario where transmitted data has a certain periodicity, including but not limited to specific scenarios such as eMBB, XR, URLLC. In addition, the embodiment of the application is not limited to the data transmission direction, and can be applied to uplink or downlink data transmission scenes. For example, fig. 1 is a schematic diagram of a communication scenario provided in an embodiment of the present application, where the communication scenario includes a network device and a terminal device. Wherein, the sending of data from the terminal device to the network device is referred to as uplink data transmission, and the sending of data from the network device to the terminal device is referred to as downlink data transmission, as shown in fig. 1.

The network device may be a device capable of communicating with the terminal device. The network device may be a base station, a relay station, or an access point. The base station may be a base transceiver station (base transceiver station, BTS) in a global system for mobile communications (global system for mobile communication, GSM) or a code division multiple access (code division multiple access, CDMA) network, a 3G base station NodeB in a wideband code division multiple access (wideband code division multiple access, WCDMA) system, or evolutional NodeB (abbreviated eNB or eNodeB) in a long term evolution (long term evolution, LTE) system. The network device may also be a wireless controller in the context of a cloud wireless access network (cloud radio access network, CRAN). The network device may also be a network device in a 5G network or a network device in a future evolved public land mobile network (public land mobile network, PLMN) network. The network device may also be a wearable device, an in-vehicle device, or a network device applied in a next generation network (e.g. 6G).

The terminal device may be a User Equipment (UE), an access terminal, a terminal unit, a terminal station, a mobile station, a remote terminal, a mobile device, a terminal, a wireless communication device, a terminal agent, a terminal apparatus, or the like. An access terminal may be a cellular telephone, a cordless telephone, a session initiation protocol (session initiation protocol, SIP) phone, a wireless local loop (wireless local loop, WLL) station, a personal digital assistant (personal digital assistant, PDA), a handheld device with wireless communication capabilities, a computing device or other processing device connected to a wireless modem, an in-vehicle device, a wearable device, a terminal device in a 5G network, a terminal device in a future evolved PLMN network or a terminal device in a next generation network (e.g., 6G), etc.

The technical scheme provided by the embodiment of the application can be applied to wireless communication among communication equipment. The wireless communication between the communication devices may include: wireless communication between a network device and a terminal device, wireless communication between a network device and a network device, and wireless communication between a terminal device and a terminal device. In this embodiment of the present application, the term "wireless communication" may also be simply referred to as "communication", and the term "communication" may also be described as "data transmission", "information transmission" or "transmission". The technical scheme can be used for performing wireless communication between the scheduling entity and the subordinate entity, and a person skilled in the art can use the technical scheme provided by the embodiment of the application for performing wireless communication between other scheduling entities and the subordinate entity, for example, wireless communication between a macro base station and a micro base station, for example, wireless communication between a first terminal device and a second terminal device.

For ease of understanding, the following detailed description is provided with respect to definitions of terms related to embodiments of the present application.

Cg transport mechanism: the 3GPP standard introduces CG transport mechanisms for uplink traffic with periodic features. The CG transmission mechanism pre-configures scheduling resources for the periodical uplink data transmission service, when the terminal equipment needs to carry out uplink data transmission, the terminal equipment does not need to wait for DCI information of the base station, and the configured resources are directly used for carrying out uplink data transmission. Specifically, CG transfer mechanisms are classified into two types.

Configuration authorization type1 (CG type 1): the flow of CG type1 is shown in fig. 2 a. The parameters in CG type1 are all configured by the cell (information element, IE) configuration grant in radio resource control (radio resource control, RRC) signaling. Wherein the cell configuration GrantConfig includes not only period information, but also frequency domainResource allocation (frequency domain resource allocation, FDRA) and time resource allocation (time domain resource allocation, TDRA) information. Wherein, assuming that the configured CG period is P, the starting time t of each CG period after CG is validated _i The terminal device can directly use the preconfigured resources to perform uplink data transmission until receiving the DCI to indicate that the reconfiguration resources or CG fails, so that DCI overhead is saved and scheduling delay is reduced.

Configuration authorization type 2 (CG type 2): the flow of CG type 2 is shown in fig. 2 b. The flow of CG type 2 is similar to that of CG type1, but no time-frequency domain resources are configured in RRC signaling configured grant. The information of the time-frequency domain resources (including FDRA and TDRA) is configured by DCI format 0. The DCI is configured only once, and the configuration mode is consistent with the existing DCI configuration mode.

2. Configurable CG period: the CG periods currently supported are shown in table 2.

Table 2: relation table of subcarrier spacing and configurable CG period

It can be seen from the above table 2 that CG periods of time slots that are non-integer multiples of more than one time slot are currently not configurable. For example, a CG period of 21 symbols (1.5 times slot) cannot be configured.

SPS transmission mechanism: the 3GPP standard introduces SPS transmission mechanisms for downlink traffic with periodic features. The SPS transmission mechanism pre-configures scheduling resources for the periodic downlink data transmission service, and then the terminal device may periodically receive the corresponding PDSCH. The network device does not need to schedule the PDSCH resources through the PDCCH before transmitting the downlink data each time, thereby reducing the signaling overhead for downlink data transmission. The flow of the SPS mechanism is shown in fig. 3, and the flow of the SPS is similar to CG type 2. The information such as the period is configured by SPS-Config in RRC, and the information such as the time-frequency domain resource is indicated by DCI format 1. The DCI needs to be configured only once, and the configuration mode is consistent with the existing DCI configuration mode.

4. Configurable SPS period: the currently configurable SPS period includes the following values: 10ms,20ms,32ms,40ms,64ms,80ms,128ms,160ms,320ms,640ms, etc. Assuming that the SPS period is P, the length of one time slot is T _slot The SPS period value can be converted into P/T _slot Time slot times. For example, table 3 is a table of the relationship between different SCS and slot lengths.

Table 3: relation table of subcarrier spacing and time slot length

It can be deduced from the above table 3 that the SPS periods currently supported are all integer time slots.

5. Data period: representing the data transmission period of a service having periodicity. In practice many services have periodicity but their data period T _p Is not necessarily an integer multiple of the time slot. For example, the frame rates of common video frames include, but are not limited to, 30FPS, 60FPS, 90FPS, 120FPS, etc., and the data periods corresponding to the different video frame rates are shown in table 4.

Table 4: relation table of frame rate and data period

Wherein, from tables 2 and 4 above, or tables 3 and 4, it can be deduced that there may be a mismatch of the data period and the configurable SPS/CG period. Data period and SPS/CG periodMismatch of (a) may result in a certain time instant (e.g., t=t _p ) The data corresponding to the data period arrives, but there is no resource corresponding to SPS/CG scheduling. It is necessary to wait for the next resource (e.g., t=2p, p is SPS/CG period) to occur for data transmission, as shown in fig. 4. In the case shown in fig. 4, the mismatch of the data period and the SPS/CG period causes additional delay, which affects the performance of the traffic for traffic with strict delay requirements (e.g., URLLC traffic or XR traffic).

It should be noted that, in the embodiment of the present application, the uplink data transmission scene corresponds to an uplink configuration authorization scene (including an uplink CG type1 scene and an uplink CG type2 scene), and the downlink data transmission scene corresponds to a downlink semi-persistent scheduling scene (i.e., a downlink SPS scene).

Fig. 5 is a flowchart of a resource allocation method according to an embodiment of the present application. The resource allocation method is executed by the network device, may be executed by a component (such as a processor, a chip, or a chip system) of the network device, and may be implemented by a logic module or software capable of implementing all or part of functions of the network device, including the following steps:

501, the network device determines a first configuration period from the configurable SPS/CG periods that satisfies a first relationship or a second relationship with the data arrival time based on the data arrival time.

It should be noted that in the scenario of uplink data transmission, before step 501, the steps are further included: the network device receives the data arrival time from the terminal device. That is, in the scenario of uplink data transmission, the network device receives the data arrival time first, so as to implement information interaction between the network device and the terminal device about the data arrival time. For example, in the uplink configuration authorization scenario, the network device receives the data arrival time of the uplink data reported by the terminal device, and then determines a first configuration period satisfying a first relationship or a second relationship with the data arrival time from the configurable configuration authorization CG period according to the data arrival time of the uplink data reported by the terminal device, so that information between the network device and the terminal device is aligned.

For the downlink data transmission scenario, the network device may determine, directly according to the data arrival time, a first configuration period that satisfies a first relationship or a second relationship with the data arrival time from the configurable SPS periods.

It will be appreciated that in step 501, no distinction is made between uplink and downlink scenarios, where an uplink scenario corresponds to a CG period and a downlink scenario corresponds to an SPS period, which are collectively described herein.

Wherein the data arrival time is the actual arrival time of the data or the data period. That is, the data arrival time may be a data period having a periodicity of regularity, for example, for a video frame with a frame rate of 60FPS, the data arrival time is a data period T having a periodicity of regularity _p =16.67 ms; the data arrival time may also be the actual arrival time of the data, and as previously exemplified, the data arrival time may be 16.67ms, 33.34ms, 50.01ms, etc., although the data arrival time may also have no periodicity, for example, the data arrival time may be 1ms, 2ms, 3.5ms, 4ms, etc.

The configurable SPS or CG period may be a period specified by an existing protocol. For example, a configurable CG period may be obtained according to table 2, e.g. 2,7, n x 14, where n= {1,2,4,5,8,10,16,20,32,40,64,80,128,160,320,640}, in sym. According to the protocol specification, the configurable SPS period includes, but is not limited to, the following values: 10ms,20ms,32ms,40ms,64ms,80ms,128ms,160ms,320ms,640ms, etc.

In one possible implementation, the network device determines a minimum period of the configurable SPS or CG periods that is greater than the data arrival time as the first configuration period when one or more periods are present in the configurable SPS or CG periods that is greater than the data arrival time. Wherein one or more of the configurable SPS or CG periods exist that are greater than the data arrival time, including the following two cases:

case one: among the configurable SPS or CG periods are SPS or CG periods that are greater than the data arrival time and SPS or CG periods that are less than the data arrival time.

And a second case: all SPS or CG periods in the configurable SPS or CG period are greater than the data arrival time.

It should be noted that in both cases, the network device selects the minimum period in the SPS or CG period that is greater than the arrival time of the data as the first configuration period, and each time the data arrives, there is a configured SPS or CG period and its configured resources for implementing data transmission between the network device and the terminal device.

For example, for a video frame with a frame rate of 60FPS, the data arrival time is the data period T with periodicity regularity _p =16.67 ms. In the scenario of upstream data transmission, according to table 2, for CG with scs=120 kHz, it is assumed that the configurable CG period is expressed as

Wherein P is ₀ ^CG ＝2sym，P ₁ ^CG =7sym, etc., the unit sym represents an orthogonal frequency division multiplexing (orthogonal frequency division multiplexing, OFDM) symbol under SCS of 120 kHz. Since the data arrival time does not coincide with the unit of the configurable CG period, the data arrival time can be converted into units of symbols. For example, for scs=120 kHz, one slot has a length of T _slot =0.125 ms, then one symbol has a length of (0.125/14) ms, then T _p ＝16.67ms＝1886.7sym(T _p May not be an integer number of OFDM symbols). Selecting a CG period greater than T from a configurable CG period _p For minimum period (e.g. greater than T _p And is closest to T _p CG period of (2) is a first configuration period, e.g., according to table 2, greater than 1886.7sym and the nearest CG period is 160×14=2240 sym, the first configuration period is P ^CG =2240 sym. Similarly, for video frames with a frame rate of 60FPS, in the context of downstream data transmission, the configurable SPS period is denoted +.>

Wherein->

P ₁ ^SPS =20ms, etc. Selection from configurable CG periodsGreater than T _p The minimum period of (1) is the first configuration period, the first configuration period is P ^SPS ＝20ms。

In yet another possible implementation, the network device determines a maximum period of the configurable SPS or CG period as the first configuration period when both the configurable SPS or CG period is less than the data arrival time.

For example, assume that the data arrival time is a data period T with a periodicity law _p =700 ms. For CG with scs=15 kHz, one slot length is T _slot =1 ms, then T _p =700 slot=9800 sym. In the scenario of uplink data transmission, according to table 2, for CG with scs=15 kHz, the maximum period in the configurable CG period is 14×640=8960 sym, less than T _p The first configuration period is P ^CG =8960 sym. Similarly, for data period T _p In the scenario of downlink data transmission, the maximum period in the configurable SPS period is 640ms, less than T =700 ms _p The first configuration period is P ^SPS ＝640ms。

Optionally, the network device may determine a period adjustment parameter according to the first configuration period and the data arrival time, where the period adjustment parameter is used to adjust the first configuration period to the second configuration period. The period adjustment parameters may include, but are not limited to, a period offset or a scaling factor. For example, the period offset is added or subtracted on the basis of the first configuration period, thereby adjusting the first configuration period to the second configuration period. For another example, a scaling factor is multiplied on the basis of the first configuration period to adjust the first configuration period to the second configuration period.

It will be appreciated that in the context of upstream or downstream data transmission, the method of calculating the period adjustment parameters is similar, and for ease of description, hereinafter the first configuration period is denoted by P (P is referred to ^CG And P ^SPS ). For example, when the period adjustment parameter is a period offset, after the network device determines the first configuration period P, the period offset corresponding to each period satisfies:

wherein p is _i A period offset representing the ith first configuration period, T _p Representing the data arrival time, P represents the first configuration period,

representation->

The value of (2) is rounded down. It should be noted that the pair ++in equation (1)>

The processing of the values of (2) may also be rounding or up-rounding, and the present embodiment is not limited thereto. Wherein the value of M is according to T _p And a least common multiple of P, M satisfying:

for example, assume that the data arrival time is T _p =21 sym, the first configuration period is p=14 sym. From equation (2), m=3 can be obtained or determined. According to equation (1), p can be obtained or determined ₀ ＝0sym，p ₁ ＝7sym，p ₂ =14 sym, as shown in fig. 6.

Optionally, when the period adjustment parameter is a scaling factor, after the first configuration period P determined by the network device, the scaling factor satisfies:

wherein α represents a scaling factor, T _p Representing the data arrival time, P represents the first configuration period. For example, assume that the data arrival time is T _p =21 sym, the first configuration period is p=14 sym. According to formula (3), α=1.5 is determined. The first configuration period is multiplied by a scaling factor,a second configuration period P' =21 sym is obtained.

The second configuration period matches the data arrival time. "match" here means that the second configuration period is the same as the data arrival time, or that the difference between the second configuration period and the data arrival time is satisfied within one slot range. For example, assume that the data arrival time is T _p =21 sym, the first configuration period is p=14 sym. According to the foregoing calculation method of the period adjustment parameter, the second configuration period P' =21 sym is determined, and the second configuration period is the same as the data arrival time. For another example, if the data arrival time is not an integer number of OFDM symbols, the second configuration period determined according to the first configuration period and the period adjustment parameter is an integer number of OFDM symbols, and the difference between the second configuration period and the data arrival time is satisfied within one slot range. It should be noted that the first configuration period is a number. For example, the first configuration period is p=14 sym. The second configuration period may be a number or a vector (the vector includes the actual time of the second configuration period). For example, as shown in fig. 6, the second configuration period P' is the first configuration period P based on the period offset P _i Corrected period P' =21 sym; since the second configuration period has a periodic characteristic, a subsequent period value can be derived from P' =21 sym. For another example, the second configuration period shown in fig. 6 is a vector P' = [0p+p ₀ ,P+p ₁ ,2P+p ₂ ,...]＝[0sym,21sym,42sym,...]。

502, the network device sends a first configuration period to the terminal device.

Specifically, for the uplink configuration grant scenario, step 502a may be performed; for the downlink semi-static scheduling scenario, step 502b may be performed.

502a, the network device sends a first configuration period to the terminal device.

502b, the network device sends a first configuration period and a data arrival time to the terminal device.

Alternatively, the network device may send the second configuration period directly to the terminal device, the second configuration period matching the data arrival time.

Specifically, for steps 502a or 502b, the first configuration period or the second configuration period may be indicated by the network device through RRC, and the data arrival time may be indicated through RRC, or may be indicated through other signaling, which is not limited in this application.

For step 502a, in one implementation, the network device sends a first configuration period to the terminal device. It may be appreciated that in the uplink configuration authorization scenario, the terminal may be configured as a data sender to know the data arrival time, and after the terminal device receives the first configuration period, the period adjustment parameter may be determined according to the first configuration period and the data arrival time. Further, the first configuration period is modified according to the period adjustment parameter, and the second configuration period is determined. Optionally, when the network device sends the first configuration period to the terminal device, the network device may also send the period adjustment parameter to the terminal device at the same time, so that the terminal device directly corrects the first configuration period according to the period adjustment parameter, and determines the second configuration period. In another implementation manner, the network device directly sends the second configuration period, and the terminal can directly know the adjusted configuration period matched with the data arrival time, so that the calculation complexity is low.

For step 502b, in one implementation manner, in the downlink semi-static scheduling scenario, the network device sends a first configuration period and a data arrival time to the terminal device, so that the terminal device determines a period adjustment parameter and a second configuration period according to the data arrival time and the first configuration period, and realizes correction of the first configuration period and alignment of information with the network device. In another implementation manner, the network device sends the second configuration period to the terminal device, and the terminal device can directly know the adjusted configuration period matched with the data arrival time, so that the calculation complexity is low.

Further, for step 502a or 502b, in an implementation manner that the network device sends the first configuration period to the terminal device, the network device also sends the configuration resource corresponding to the first configuration period to the terminal device. For example, the configuration resources include time-frequency resources, and the like. The configuration resources may also be indicated by the network device through RRC. And the network equipment performs data transmission with the terminal equipment in the corrected second configuration period by adopting configuration resources corresponding to the first configuration period. That is, the network device does not reconfigure the new resources for the second configuration period, only the period when actually transmitting is modified from the first configuration period to the second configuration period, the adopted resources are not changed, and the configuration resources corresponding to the first configuration period are still adopted.

The embodiment of the application provides a resource configuration method, by which network equipment realizes that SPS/CG period is matched with data arrival time by correcting the SPS/CG period in an uplink configuration authorization scene or a downlink semi-persistent scheduling scene. The method is beneficial to having corresponding configured resources when the data arrives each time, so that the network equipment can adopt the corresponding configured resources to carry out data transmission, thereby reducing the time delay of the data transmission.

The following describes a specific flow of the resource allocation method shown in fig. 5 applied to an uplink allocation grant scenario or a downlink semi-static scheduling scenario.

Fig. 7 is a flowchart illustrating the application of the resource allocation method shown in fig. 5 to the uplink CG type1 scenario, and the description in fig. 5 is applicable to fig. 7, and reference may be made between fig. 5 and fig. 7. The process is realized by interaction between the network equipment and the terminal equipment, and comprises the following steps:

701, the terminal device sends data arrival time to the network device; correspondingly, the network device receives the arrival time of the data from the terminal device. For example, the data arrival time is the data period T _p I.e. the start or end time interval between each batch of data is T _p 。

The network device determines 702 a CG period (i.e., a first configuration period) that satisfies a first relationship or a second relationship with the data arrival time based on the data arrival time. For example, a minimum period larger than the data arrival time is selected as a CG period from among the configurable CG periods, and a period adjustment parameter for each CG period is determined based on the selected CG period and the data arrival time.

703, the network device sends an RRC indication message to the terminal device, where the RRC indication message is used to indicate the first configuration period and the time-frequency domain resources configured by the first configuration period; correspondingly, the terminal device receives the RRC indication message from the network device. For example, the network device indicates the first configuration period through the periodicity in RRC signaling configuredgrantconfigug. It should be noted that, the network device may also indicate other parameters (such as a time domain offset, such as timeDomainOffset) through RRC signaling, and the specific implementation may be implemented according to an existing CG configuration, which is not limited in this embodiment.

Alternatively, step 703 may be replaced with step 703a, where the network device determines a second configuration period (i.e. a corrected CG period) according to the first configuration period and the period adjustment parameter of the first configuration period. The network device sends an RRC indication message to the terminal device, where the RRC indication message is used to indicate the second configuration period and the time-frequency domain resources configured by the second configuration period.

The terminal device determines 704 a second configuration period based on the first configuration period and the data arrival time.

Optionally, the terminal device directly receives the second configuration period sent by the network device.

And 705, the terminal equipment performs data transmission with the network equipment according to the time-frequency domain resources configured in the second configuration period. For example, the second configuration period shown in FIG. 7 is iP+p _i I=0, 1..m-1, wherein the manner of determination of M refers to formula (2). And the terminal equipment transmits uplink data to the network equipment according to the time-frequency domain resources configured in the second configuration period in each second configuration period.

Optionally, step 705 configures the corrected CG period to be ip+p _i I=0, 1..m-1 (i.e., CG period after the i-th correction); however, based on the characteristic of CG periodicity, for the i+nm period, n is a positive integer, and before CG period fails or is reconfigured, the network device and the terminal device can cycle through the i+nm period to use the i+corrected CG period, i.e. at (i+nm) p+p _i The period is still according to iP+p _i And periodically configuring resources to perform data transmission.

Fig. 8 is a schematic flow chart of the resource allocation method shown in fig. 5 applied to the uplink CG type2 scenario, and the description in fig. 5 applies to fig. 8, and reference may be made between fig. 5 and fig. 8. The process is realized by interaction between the network equipment and the terminal equipment, and comprises the following steps:

801, the terminal device sends data arrival time to the network device; correspondingly, the network device receives the data arrival time of the device from the terminal.

The network device determines 802 a CG period (i.e., a first configuration period) that satisfies a first relationship or a second relationship with the data arrival time based on the data arrival time. The network device may also determine a period adjustment parameter based on the data arrival time and the first configuration period.

803, the network device sends an RRC indication message to the terminal device, where the RRC indication message is used to indicate the first configuration period; correspondingly, the terminal device receives the RRC indication message from the network device.

Alternatively, step 803 may be replaced with 803a, where the network device determines the second configuration period (i.e., the corrected CG period) according to the first configuration period and the period adjustment parameter of the first configuration period. The network device sends an RRC indication message to the terminal device, the RRC indication message being used to indicate the second configuration period.

804, the network device sends a DCI indication message to the terminal device, where the DCI indication message is used to indicate the time-frequency domain resources configured in the first configuration period; correspondingly, the terminal device receives the DCI indication message from the network device.

Alternatively, step 804 may be replaced by 804a, where the network device sends a DCI indication message to the terminal device, where the DCI indication message is used to indicate the time-frequency domain resources configured in the second configuration period.

805, the terminal device determines a second configuration period (i.e. a corrected CG period) according to the first configuration period and the data arrival time; alternatively, the terminal device receives the corrected CG period directly from the network device.

806, the terminal device performs data transmission with the network device in each second configuration period according to the time-frequency domain resources configured in the first configuration period. The specific implementation refers to the corresponding description in step 705, and will not be described in detail here.

Fig. 9 is a schematic flow chart of the resource allocation method shown in fig. 5 applied in a downlink SPS scenario, and the related description in fig. 5 applies to fig. 9, and reference may be made between fig. 5 and fig. 9. The process is realized by interaction between the network equipment and the terminal equipment, and comprises the following steps:

901a, a network device sends data arrival time to a terminal device; correspondingly, the terminal device receives the arrival time of the data from the network device.

901b, the network device determines, according to the data arrival time, an SPS period (i.e., a first configuration period) that satisfies a first relationship or a second relationship with the data arrival time. The network device may also determine a period adjustment parameter based on the data arrival time and the first configuration period.

Note that 901a and 901b are not strictly sequential in execution, for example, 901a may be executed first and 901b may be executed later; or, first 901b is executed, then 901a is executed; or both 901a and 901b may be performed simultaneously.

902, the network device sends an RRC indication message to the terminal device, where the RRC indication message is used to indicate a first configuration period; correspondingly, the terminal device receives the RRC indication message from the network device.

Alternatively, step 902 may be replaced with step 902a, where the network device determines a second configuration period (i.e., a corrected SPS period) according to the first configuration period and the period adjustment parameter of the first configuration period. The network device sends an RRC indication message to the terminal device, the RRC indication message being used to indicate the second configuration period.

903, the network device sends a DCI indication message to the terminal device, where the DCI indication message is used to indicate the time-frequency domain resource configured in the first configuration period; correspondingly, the terminal device receives the DCI indication message from the network device.

Alternatively, step 903 may be replaced by 903a, where the network device sends a DCI indication message to the terminal device, where the DCI indication message is used to indicate the time-frequency domain resources configured in the second configuration period.

904, the terminal equipment determines a second configuration period (namely, a corrected SPS period) according to the first configuration period and the data arrival time; alternatively, the terminal device receives the second configuration period directly from the network device.

905, in the second configuration period, the terminal device performs data transmission with the network device according to the time-frequency domain resources configured in the first configuration period or the second configuration period. For example, the corrected SPS period shown in FIG. 9 is iP+p _i I=0, 1..m-1, wherein the manner of determination of M refers to formula (2). And the terminal equipment receives downlink data from the network equipment in the second configuration period according to the time-frequency domain resources configured in the first configuration period or the second configuration period.

Optionally, step 905 configures the SPS period for the correction to be ip+p _i I=0, 1..m-1 (i.e., the i-th corrected SPS period); however, based on the characteristics of SPS periodicity, for the i+nM th period, n is a positive integer and the network device and terminal device can cycle through the corrected SPS period at the i+nM th period, i.e., at (i+nM) P+p, before the SPS period fails or is reconfigured _i The period is still according to iP+p _i And periodically configuring resources to perform data transmission.

Fig. 10 is a flowchart of another resource allocation method according to an embodiment of the present application. The resource allocation method is executed by the network device, may be executed by a component (such as a processor, a chip, or a chip system) of the network device, and may be implemented by a logic module or software capable of implementing all or part of functions of the network device, including the following steps:

1001, the network device determines a data amount of a gear and a reference resource according to the data amount information, where the data amount of the gear is used to determine a gear to which the data amount belongs.

The data volume information comprises data volume corresponding to data arrival time. The data volume information may be embodied in the form of a data volume vector, e.g. data volume vector s= [ s ] ₀ ,s ₁ ,...,s _N-1 ]Wherein s is _j Represented by j T _p Data amount at time, j=0, 1,.. _p Representing the data arrival time, here specifically the data period. Wherein the length N of the data volume vector may be determined by the data volume information sender (e.g. a terminal device or a network device) itself.

The result of the data amount's stepping includes one or more of the stepping number or the reference data amount or the gear to which the data amount belongs. The number of steps is used to represent the number of steps of the data amount, the step to which the data amount belongs can be understood as the step corresponding to each data amount, and the step to which the data amount belongs can be represented by a step vector.

It should be noted that in the scenario of uplink data transmission, before step 1001, the steps are further included: the network device receives data volume information from the terminal device. That is, in the scenario of uplink data transmission, the network device receives the data amount information first, and then determines the data amount classification result and the reference resource according to the data amount information. In the downlink data transmission scenario, the network device is used as a data sender, knowing the data volume information to be sent by the network device, and the network device can directly determine the grading result and the reference resource of the data volume according to the data volume information.

In one implementation, the result of the upshift of the data volume is the gear (e.g., upshift vector) to which the data volume belongs. Specifically, determining the gear to which the data amount belongs according to the data amount information may include the following implementation manners:

example one: a determination criterion for presetting the number of steps and the amount of preset reference data.

Specifically, the network device may determine the reference data amount by using a predefined criterion, for example, a data amount obtained by taking a maximum data amount or a minimum data amount or a data amount average value or other value taking modes in the data amount information as the reference data amount, where the criterion is predefined or preconfigured, and the network device only needs to determine the reference data amount according to the criterion. Exemplary, the data volume vector s= [ s ] ₀ ,s ₁ ,...,s _N-1 ]Determining a maximum data quantity S in a data quantity vector _ref ＝S _max ＝maxs _j As the reference data quantity S _ref May also be the minimum value in the data vectorMean value, etc. as reference data quantity S _ref The present application is not limited.

The network device can preset or preconfigure a number of steps L, and for any data traffic, the network device adopts the preset number of steps and combines the reference data quantity S _ref Determining a shift vector l= [ l ] ₀ ,l ₁ ,...,l _N-1 ]. Wherein the gear vector l= [ l ] ₀ ,l ₁ ,...,l _N-1 ]Corresponding data quantity vector s= [ s ] ₀ ,s ₁ ,...,s _N-1 ]The data amount of each data in the range is a gear l _i I=0, 1,... That is, for the data amount vector s= [ s ] ₀ ,s ₁ ,...,s _N-1 ]Gear and gear vector l= [ l ] to which each data amount belongs ₀ ,l ₁ ,...,l _N-1 ]One-to-one correspondence; for example, s ₀ The corresponding gear is l ₀ ，s ₁ The corresponding gear is l ₁ ，s ₂ The corresponding gear is l ₂ And so on. In such an implementation, the result of the stepping of the amount of data determined by the network device comprises a stepping vector l= [ l ] ₀ ,l ₁ ,...,l _N-1 ](i.e. comprising the gear l to which the data quantity belongs) _i )。

For example, if the network device presets the number of steps l=4, the network device pairs the data volume vector s= [ s ] according to the preset number of steps ₀ ,s ₁ ,...,s _N-1 ]And performing gear shifting. S is S _ref Representing the reference data quantity, if

The data quantity s _i The gear is the 0 th gear (i.e. l _i =0); if->

The data quantity s _i The gear is 1 st gear (i.e. l _i =1); if it is

The data quantity s _i The gear is the 2 nd gear (i.e. l _i =2); if->

The data quantity s _i The gear is 3 rd gear (i.e. l _i ＝3)。

Example two: the number of steps is not preset, and the determination criterion of the reference data amount is preset.

Specifically, if the network device does not preset or preconfigured a number of steps L, the network device may determine that the data amount vector s= [ s ] ₀ ,s ₁ ,...,s _N-1 ]Determining the number of steps L, further, determining the reference data quantity by the network equipment according to the preset determination criterion of the reference data quantity, and combining the reference data quantity S _ref Determining the gear to which the data amount belongs.

Specifically, in this implementation, the network device determines a dynamic range of the data volume according to the data volume vector, and further determines the number of steps according to the dynamic range of the data volume. For example, as shown in fig. 11, the dynamic change of the data amount can be divided into three ranges, e.g., 0bit to 1×10 ² bit represents the first variation range, 1 x 10 ² bit to 1 x 10 ⁴ bit represents the second variation range, 1 x 10 ⁴ bit to 1 x 10 ⁸ bit represents the third range of variation. The network device determines the number of steps l=3.

Wherein the gear vector l= [ l ] ₀ ,l ₁ ,...,l _N-1 ]The value of l _i The method meets the following conditions:

wherein S is _ref Representing the reference data quantity s _i Data quantity representing the i-th data arrival time, l _i Representation s _i The corresponding gear, L, represents the number of steps.

For example, according to equation (4), if

The data quantity s _i The gear is the 0 th gear (i.e. l _i =0); if it is

The data quantity s _i The gear is 1 st gear (i.e. l _i =1); if->

The data quantity s _i The gear is the 2 nd gear (i.e. l _i =2), as shown in fig. 11.

Example three: the number of steps is preset, and the determination criterion of the reference data amount is not preset.

In the implementation of the determination criterion of the preset reference data amount, the network device needs to determine the reference data amount first, where the preset number of steps is not preset, and for example, the network device may determine the reference data amount according to the overall situation of the data amount information. For example, according to the data amount vector s= [ s ] in the data amount information ₀ ,s ₁ ,...,s _N-1 ]Determining a maximum data quantity S in a data quantity vector _ref ＝S _max ＝maxs _j As the reference data quantity S _ref The minimum value, average value, etc. in the data vector may be used as the reference data amount S _ref The present application is not limited. Further, the gear to which the data amount belongs is determined based on the preset gear number, the reference data amount and the data amount information.

Example four: the number of steps is not preset, and the criterion for determining the reference data amount is not preset.

In the implementation manner of the determining criteria of the number of non-preset steps and the number of non-preset reference data, the network device may determine the number of preset steps and the number of reference data according to the data amount information, and may refer to the implementation manner of the determining criteria of the number of non-preset steps or the number of non-preset reference data in the foregoing embodiment, which is not described herein in detail. Further, after determining the number of steps and the reference data amount, the data amount information can be combined to determine the gear to which the data amount belongs.

In yet another possible implementation, the result of the stepping of the data amount includes a number of steps. For example, in the case where the number of steps is not preset, the result of the step of the data amount determined by the network device may be directly the number of steps.

In yet another possible implementation, the result of the grading of the data volume includes a reference data volume. For example, in the case where the reference data amount is not preset, the result of the stepping of the data amount determined by the network device may be directly the reference data amount.

In yet another possible implementation, the data amount of the step result includes a step number and a reference data amount. For example, in the case where the number of steps and the reference data amount are not preset, the result of the step of the data amount determined by the network device may be the number of steps and the reference data amount.

Further, the network device determining the reference resource according to the data volume information may include: the network device determines a reference data quantity S according to the data quantity information _ref According to the reference data quantity S _ref The reference resource is further determined. For example, according to the data amount vector s= [ s ] in the data amount information ₀ ,s ₁ ,...,s _N-1 ]Determining a maximum data quantity S in a data quantity vector _ref ＝S _max ＝maxs _j As the reference data quantity S _ref Determining reference resource as transmission reference data quantity S _ref The time-frequency domain resource to be configured can be used as the reference data quantity S by using the minimum value, the average value and the like in the data vector _ref The present application is not limited.

The reference resource may also be understood as a reference resource, which is used to determine a resource corresponding to a gear to which the data amount in each resource allocation period belongs. For example, the reference resources may include a size and/or location of time domain resources and a size and/or location of frequency domain resources, referred to as reference time domain resources and reference frequency domain resources, respectively. Wherein the resource configuration period is the first configuration period or the second configuration period described in the embodiment of fig. 5. That is, the network device performs the data amount classification in the scene where the SPS/CG period is not corrected, and in the scene where the SPS/CG period is corrected.

Further, based on the reference resource, the network device may determine, according to the gear to which the data amount corresponding to each resource allocation period belongs, the resource corresponding to the gear. The network device and the terminal device may pre-configure a mapping criterion, where the mapping criterion is used to predefine a mapping relationship between resources corresponding to the data ranges and the reference resources, that is, the network device and the terminal device may know actual resources corresponding to each data range according to the mapping criterion and the reference resources. For example, assume that the time slot occupied by the reference time domain resource is 8 time slots, and the time slot position is time slots 0-7; the frequency size occupied by the reference frequency domain resource is assumed to be 16MHz, and the frequency range is 16MHz-31MHz. Suppose that the 0 th stage uses resources with the same size and position as the reference time domain resources (i.e. the 0 th stage uses 8 time slots, the time slot positions are time slots 0-7), and frequency domain resources with the same size and position as the reference frequency domain resources (i.e. the 0 th stage uses frequency with the size of 16MHz and the frequency range of 16MHz-31 MHz); the 1 st stage uses the time domain resource with the same size and position as the 1/2 reference time domain resource (namely, the 1 st stage uses 4 time slots, the time slot positions are time slots 0-3 or time slots 4-7), and the frequency domain resource with the same size and position as the reference frequency domain resource (namely, the 1 st stage uses the frequency with the size of 16MHz and the frequency range of 16MHz-31 MHz); from this, it can be seen that the size and location of the time domain resource used in gear 1 is changed from that used in gear 0. Similarly, stage 2 uses time domain resources of the same size and location as the 1/2 reference time domain resources (i.e., stage 2 uses 4 time slots with slot positions of slots 0-3 or slots 4-7), and frequency domain resources of the same size and location as the 1/2 reference frequency domain resources (i.e., stage 2 uses frequency of 8MHz with frequency range 16MHz-23MHz or frequency range 24MHz-31 MHz); the 3 rd gear uses the same size and position time domain resources as the 1/4 reference time domain resources (i.e., the 3 rd gear uses 2 time slots with

time slots

0 and 1, or

time slots

2 and 3, or time slots 4 and 5, or time slots 6 and 7), and the same size and position frequency domain resources as the 1/2 reference frequency domain resources (i.e., the 3 rd gear uses frequency with 8MHz, frequency range 16MHz-23MHz, or frequency range 24MHz-31 MHz), and so on, as shown in fig. 12.

In an implementation manner of determining, by the network device, a resource corresponding to the associated gear according to the gear to which the data amount of each resource allocation period belongs, for frequency domain resource allocation (frequency domain resource allocation, FDRA), the method includes the following two cases:

case one: if the frequency domain resource allocation (FDRA type 0) is type 0, that is, the frequency domain resource is indicated by adopting a bitmap (bitmap), the front part of the effective resource in the bitmap is acquired according to the proportion corresponding to the grading. And if the ratio of the effective bit number multiplied by the grading is a non-integer, rounding upwards. For example, a method for determining a resource corresponding to a gear to which FDRA type 0 belongs from a resource is shown in fig. 13, where a hatched box indicates that its corresponding Resource Block (RB) resource can be used for transmitting data. When the data amount of the resource allocation period belongs to the 0 th gear, the time domain resource corresponding to the 0 th gear is the RB resource corresponding to the shaded box (7 "1" in total) with the number "1" in the FDRA of 1 times in fig. 13. Similarly, when the shift position to which the data amount of the resource allocation period belongs is 1 st shift, the time domain resource corresponding to 1 st shift is RB resource corresponding to a shaded box with the number "1" (4 "1" s in total) in the FDRA of 1/2 times in fig. 13.

And a second case: if the frequency domain resource allocation (FDRAtype 1) of the type 1 is indicated by adopting a resource indication value (resource indication value, RIV) mode, the indicated length is directly converted according to the proportion corresponding to the step. And if the ratio of the indication length multiplied by the step is a non-integer, rounding upwards. For example, when the initial value of the frequency domain resource indication is X and the length is Y, the indicated FDRA is the RB resource corresponding to the index X to the index X+Y-1, 1 times of the FDRA is the RB resource corresponding to the index X to the index X+Y-1, and 1/2 times of the FDRA is the index X to the index

Corresponding RB resources. Wherein X and Y are positive integers.

In an implementation manner that the network device determines the resources corresponding to the corresponding gear according to the gear to which the data amount of each resource allocation period belongs, a method of starting length indication value (start length indication value, SLIV) is adopted for time domain resource allocation (time domain resource allocation, TDRA)The formula indicates. The TDRA performs resource conversion according to the fdrayype 1 method, that is, converts the length indicated by the SLIV value according to the ratio corresponding to the step, and obtains the resource corresponding to the belonging step. For example, when the initial value of the time domain resource indication is X and the length is Y, the indicated TDRA is the time domain resource corresponding to the index X to the index X+Y-1, 1 time of the TDRA is the time domain resource corresponding to the index X to the index X+Y-1, and 1/2 time of the TDRA is the index X to the index

Corresponding time domain resources.

Further, after determining the actual resources corresponding to the data amount in each resource configuration period according to the gear to which the data amount in each resource configuration period belongs and the reference resources, the network device performs data transmission with the terminal device in each resource configuration period according to the actual resources corresponding to the gear to which the data amount in each resource configuration period belongs. For example, if the gear to which the data amount in a certain resource allocation period belongs is the 0 th gear, the actual resource size and/or position corresponding to the data amount in the resource allocation period is the same as the reference time domain resource and the reference frequency domain resource, and in the allocation period, the network device uses the resource with the same size and/or position as the reference time domain resource and the reference frequency domain resource to perform data transmission with the terminal device.

In one implementation, the network device may also determine a first configuration period and a period adjustment parameter. Or the network equipment determines a second configuration period according to the first configuration period and the period adjustment parameter, and the second configuration period is matched with the data arrival time. For detailed descriptions of the first configuration period, the period adjustment parameter, and the second configuration period, and the determining method refer to corresponding descriptions in the embodiment of fig. 5, which are not repeated herein. That is, the network device can correct the SPS/CG period to match the SPS/CG period with the data arrival time; and flexible SPS/CG time-frequency domain resource allocation and scheduling can be realized, which is beneficial to adapting to the service with larger data volume dynamic range.

The network device sends 1002 the result of the grading of the data amount and the reference resource to the terminal device.

In an implementation manner of presetting a number of steps, the network device sends a step result of the data amount and a reference resource to the terminal device, where the step result of the data amount in step 1002 is specifically a step to which the data amount belongs. For example, in the scenario of the uplink CG type 1, the network device indicates, through RRC, the gear and reference resource to which the data amount belongs. For another example, in the scenario of the uplink CG type 2 or the downlink SPS, the network device indicates the gear to which the data amount belongs through RRC, and indicates the reference resource through DCI.

Alternatively, the terminal device may preset a number of steps L, and the terminal device and the network device use the same preset number of steps to step the data amount, so that the steps to which the data amounts determined by the network device and the terminal device belong are consistent. In this implementation, for the uplink data transmission scenario, since the number of steps adopted by the terminal device and the network device is the same, the network device may send the reference resource and the reference data amount to the terminal device (assuming that the reference data amount does not adopt the predefined determination criterion) without sending the gear to which the data amount belongs, and the terminal device may determine the gear to which the data amount belongs by itself according to the reference data amount, the number of steps, and the data amount information without needing the network device to send, that is, in this case, the network device sends the reference resource and the reference data amount to the terminal device, that is, the data amount step result here is the reference data amount. Further, if the terminal device also adopts the manner of determining the predefined reference data amount and is the same as the determining criteria of the predefined reference data amount of the network device, in this case, there is no need to synchronize the reference data amount between the network device and the terminal device, the network device only needs to send the reference resource to the terminal device. For the downlink data transmission scenario, in addition to the situation that the data amount of the step result is directly the gear to which the data amount belongs, the network device needs to send data amount information to the terminal device, and other scenarios similar to the uplink data scenario, for example, the network device also sends reference data amount (i.e. the preset reference data amount determining criterion is not set, the preset step number, and the data amount step result is the reference data amount), which may be specifically referred to the description of the uplink data scenario and will not be repeated herein.

In an implementation manner that the network device determines the number of steps (i.e., the number of steps not preset) according to the data amount information, the network device sends a step result of the data amount and a reference resource to the terminal device, including:

in one possible implementation, the network device sends the number of steps and the reference resource to the terminal device. That is, in this case, the number of steps is the result of the step of the data amount in step 1002. For example, in the scenario of uplink CG type 1, the network device indicates the number of steps and reference resources through RRC. For another example, in the scenario of uplink CG type 2 or downlink SPS, the network device indicates the number of steps through RRC and indicates the reference resource through DCI. It can be understood that in this case, the terminal device needs to further determine, according to the data amount information and the number of steps sent by the network device, the gear to which the data amount belongs, and for the downlink SPS scenario, the network device needs to send the data amount information to the terminal device.

In another possible implementation manner, the network device sends the gear and the reference resource to which the data quantity belongs to the terminal device. That is, in this case, the shift position (for example, shift vector) to which the data amount belongs is the shift result of the data amount in step 1002. For example, in the scenario of uplink CG type 1, the network device indicates the stepper vector and reference resources through RRC. For another example, in the scenario of uplink CG type 2 or downlink SPS, the network device indicates a stepper vector through RRC and a reference resource through DCI. It can be understood that in this case, after the network device determines the number of steps according to the data amount information, the network device further determines the gear to which the data amount belongs, and directly sends the gear to which the data amount belongs to the terminal device, so that the computational complexity of the terminal device for further determining the gear to which the data amount belongs according to the number of steps and the data amount information is reduced.

It should be noted that the foregoing is merely an exemplary illustration, and in the case where the result of the data amount is different, the description of the foregoing embodiment may be referred to determine specific information sent by the network device, and the specific details are not repeated herein.

Optionally, for the uplink configuration authorization scenario, the network device further sends a first configuration period or a second configuration period to the terminal device; for the downlink semi-static scheduling scenario, the network device further transmits a first configuration period and a data arrival time to the terminal device, or the network device transmits a second configuration period to the terminal device. Reference is made in particular to the description of the embodiment of fig. 5, which is not described in detail here.

According to the resource allocation method provided by the embodiment of the application, in an uplink allocation authorization scene or a downlink semi-static scheduling scene, the network equipment performs data size grading on the data size of the resource allocation period, and allocates corresponding time-frequency domain resources for different grading. The flexible SPS/CG time-frequency domain resource allocation and scheduling are realized, and the method is favorable for adapting to the service with larger data volume dynamic range.

The following describes a specific flow of the resource allocation method shown in fig. 10 applied to an uplink allocation grant scenario or a downlink semi-static scheduling scenario. In the embodiments shown in fig. 14 to 20, the network device and the terminal device use the result of the data amount determination in a non-preset manner as an example for explanation.

Fig. 14 is a flowchart illustrating the application of the resource allocation method shown in fig. 10 to the scenario of the uplink CG type1, and the description in fig. 10 applies to fig. 14, and reference may be made between fig. 10 and fig. 14. The flow is implemented by interaction between the network device and the terminal device. When the resource allocation method is applied to a CG type1 scene, a network device or a terminal device may determine a grading result of a data volume, where the method specifically includes the following steps:

mode one: determining, by the network device, a result of the ranking of the data amounts:

1401a, the terminal device sends data amount information to the network device; correspondingly, the network device receives data volume information from the terminal device. Wherein the data volume information includes a data volume of a data arrival time.

1402a, the network device performs quantization and grading on the data size to obtain a grading result of the data size. For example, the network device obtains the result of the data amount by the stepping manner as shown in the formula (4), including the stepping vector.

Mode two: determining, by the terminal device, a result of the ranking of the data amounts:

1401b, the terminal device performs quantization and grading on the data size to obtain a grading result of the data size. The method for quantitatively classifying the data size by the terminal device is similar to the method adopted by the network device, and is not repeated here.

1402b, the terminal device sends the data amount information and the result of the data amount classification to the network device. Correspondingly, the network device receives the data amount information from the terminal device and the grading result of the data amount.

Note that 1401a and 1401b (or 1402a and 1402 b) are parallel method steps. For example, when the result of the step of determining the data amount in the first mode is adopted, the network device and the terminal device execute steps 1401a and 1402a; when the result of the data amount classification is determined in the second mode, the network device and the terminal device execute steps 1401b and 1402b.

Further, steps 1403 to 1405 are included:

1403, the network device sends an RRC indication message to the terminal device, where the RRC indication message is used to indicate a result of the data amount of the step and a reference resource; correspondingly, the terminal device receives the RRC indication message from the network device. For example, when the result of the data amount is the number of steps, the parameter numdatasizeLevel may be increased in the ConfiguredGrantConfig in the RRC message to indicate the number of steps. It should be noted that, the network device may also indicate other parameters through RRC signaling, and the specific implementation is completed according to the existing CG configuration manner, which is not limited in this embodiment.

And 1404, the terminal equipment determines the gear to which the data quantity belongs and the resource corresponding to the gear in each resource configuration period according to the data quantity grading result and the reference resource.

1405, the terminal device performs data transmission with the network device according to the resources corresponding to the gear to which the data amount in each resource allocation period belongs in each resource allocation period. For example, the resources shown in FIG. 14The configuration period is a first configuration period (CG period satisfying a first relationship or a second relationship with the data arrival time) iP, i=0, 1,..or a second configuration period (corrected CG period) ip+p _i I=0, 1..m-1, wherein the manner of determination of M refers to formula (2). And the terminal equipment sends uplink data to the network equipment in each resource allocation period according to the time-frequency domain resource corresponding to the gear to which the data quantity in the resource allocation period belongs.

Optionally, step 1405 is directed to an ith resource allocation period; due to the characteristic of CG periodicity, for the (i+nM) th resource allocation period, n is a positive integer, and before the CG period fails or is reconfigured, the network device and the terminal device can circularly use the resource corresponding to the gear to which the data volume in the (i+nM) th resource allocation period belongs in the (i+nM) th P period (i.e. the (i+nM) th first allocation period) or (i+nM) P+p _i The period (i.e., the i+nM th second configuration period) is still in terms of the iP period or iP+p _i And carrying out data transmission on resources corresponding to the gear to which the data quantity belongs in the period.

Fig. 15 is a flowchart illustrating the application of the resource allocation method shown in fig. 10 to the scenario of the uplink CG type2, and the description in fig. 10 is applicable to fig. 15, and reference may be made between fig. 10 and fig. 15. The flow is implemented by interaction between the network device and the terminal device. When the resource allocation method is applied to an uplink CG type2 scene, a network device or a terminal device may determine a grading result of a data volume, and the method specifically includes the following steps:

1501a, a terminal device transmits data amount information to a network device; correspondingly, the network device receives data volume information from the terminal device. The data volume information comprises data volume corresponding to data arrival time.

1502a, the network device performs quantization and grading on the data size to obtain a grading result of the data size. For example, the network device obtains the result of the data amount by the step manner as shown in the formula (4).

1503a, the network device sends an RRC indication message and a DCI indication message to the terminal device, where the RRC indication message is used to indicate a result of the data amount of the step, and the DCI indication message is used to indicate the reference resource; correspondingly, the terminal device receives the RRC indication message from the network device.

1501b, the terminal device performs quantization and grading on the data size to obtain a grading result of the data size.

1502b, the terminal device sends the data volume information and the result of the data volume classification to the network device. Correspondingly, the network device receives the data amount information from the terminal device and the grading result of the data amount.

1503b, the network device sends a DCI indication message to the terminal device, where the DCI indication message is used to indicate the reference resource; correspondingly, the terminal device receives the DCI indication message from the network device.

Specifically, the network device determines an actual resource corresponding to the data amount in each resource configuration period according to the gear to which the data amount in each resource configuration period belongs and the reference resource.

Note that 1501a and 1501b (or 1502a and 1502b, or 1503a and 1503 b) are juxtaposed method steps, for example, when a result of a data amount stepping is determined in a manner, the network device and the terminal device execute steps 1501a to 1503a; when the result of the step of determining the data amount in mode two is employed, the network device and the terminal device execute steps 1501b-1503b.

Further, steps 1504 and 1505 are also included:

1504, the terminal device determines, according to the data amount classification result and the reference resource, the gear to which the data amount belongs and the resource corresponding to the gear in each resource configuration period.

1505, the terminal device performs data transmission with the network device according to the resources corresponding to the gear to which the data amount in each resource allocation period belongs in each resource allocation period.

Fig. 16 is a schematic flow chart of the resource allocation method shown in fig. 10 applied in a downlink SPS scenario, and the related description in fig. 10 applies to fig. 16, and reference may be made between fig. 10 and fig. 16. The flow is implemented by interaction between the network device and the terminal device. When the resource allocation method is applied to a downlink SPS scene, the network equipment or the terminal equipment can determine the grading result of the data quantity, and the method specifically comprises the following steps:

1601a, the network device sends data amount information to the terminal device; correspondingly, the terminal device receives data volume information from the network device.

1602a, the network device performs quantization and grading on the data size to obtain a grading result of the data size.

1603a, the network device sends an RRC indication message to the terminal device, the RRC indication message being used to indicate a result of the grading of the data amount; correspondingly, the terminal device receives the RRC indication message from the network device.

1604a, the network device sending a DCI indication message to the terminal device, the DCI indication message being for indicating the reference resource; correspondingly, the terminal device receives the DCI indication message from the network device.

Specifically, the network device determines a gear to which the data volume of each resource allocation period belongs according to the data volume grading result; and the network equipment determines the actual resources corresponding to the gears to which the data quantity belongs in each resource configuration period according to the gears to which the data quantity belongs in each resource configuration period and the reference resources.

1601b, the network device sends data amount information to the terminal device; correspondingly, the terminal device receives data volume information from the network device.

1602b, the terminal device performs quantitative grading on the data size to obtain a grading result of the data size.

1603b, the terminal device sends the result of the grading of the data volume to the network device.

1604b, the network device sending a DCI indication message to the terminal device, the DCI indication message being for indicating the reference resource; correspondingly, the terminal device receives the DCI indication message from the network device.

Specifically, the network device determines a gear to which the data volume of each resource allocation period belongs according to the data volume grading result; and the network equipment determines the resources corresponding to the gears to which the data quantity belongs in each resource allocation period according to the gears to which the data quantity belongs in each resource allocation period and the reference resources.

It should be noted that 1601a and 1601b (or 1602a and 1602b, or 1603a and 1603b, or 1604a and 1604 b) are juxtaposed method steps, e.g. when determining a result of a data amount of a step by step in a manner one, the network device and the terminal device perform steps 1601a-1604a; when the result of the step of determining the data amount in mode two is employed, the network device and the terminal device execute steps 1601b-1604b.

Further, steps 1605 and 1606 are also included:

1605, the terminal device determines, according to the data amount classification result and the reference resource, the gear to which the data amount belongs and the resource corresponding to the gear in each resource configuration period.

1606, the terminal device performs data transmission with the network device according to the resources corresponding to the gear to which the data amount in each resource allocation period belongs in each resource allocation period.

It should be noted that according to the description in the embodiment of fig. 10, the network device may correct the SPS/CG period to match the SPS/CG period with the data arrival time; and flexible SPS/CG time-frequency domain resource allocation and scheduling can be realized, which is beneficial to adapting to the service with larger data volume dynamic range. For example, fig. 17 is a flowchart showing a scenario in which the resource allocation method shown in fig. 5 and the resource allocation method shown in fig. 10 are combined and applied to the uplink CG type1, and the related descriptions in fig. 5 and fig. 10 are applicable to fig. 17, and fig. 5, fig. 10 and fig. 17 can be referred to each other. Fig. 17 illustrates an example of a result of the network device determining the data amount, and the method includes the steps of:

1701, the terminal device sends data arrival time and data volume information to the network device; correspondingly, the network device receives the data arrival time and data volume information from the terminal device.

1702a, the network device performs quantization and grading on the data size to obtain a grading result of the data size.

1702b, the network device determines, based on the data arrival time, a CG period (i.e., a first configuration period) that satisfies a first relationship or a second relationship with the data arrival time. For example, a minimum period larger than the data arrival time is selected as a CG period from among the configurable CG periods, and a period adjustment parameter for each CG period is determined based on the selected CG period and the data arrival time.

Note that 1702a and 1702b are not strictly sequential in execution, e.g., 1702a may be executed first followed by 1702b; alternatively, 1702b is performed before 1702a is performed; or both 1702a and 1702b.

1703, the network device sends an RRC indication message to the terminal device, where the RRC indication message is used to indicate the first configuration period, the result of the data volume of the step and the reference resource; correspondingly, the terminal device receives the RRC indication message from the network device.

Alternatively, step 1703 may be replaced with step 1703a, where the network device determines a second configuration period (corrected CG period) according to the first configuration period and the period adjustment parameter of the first configuration period. The network device transmits an RRC indication message to the terminal device, the RRC indication message indicating the second configuration period, a result of the grading of the data amount, and the reference resource.

1704, the terminal equipment determines a second configuration period according to the first configuration period and the data arrival time; alternatively, the terminal device directly receives the second configuration period.

1705, the terminal device determines, according to the data amount classification result and the reference resource, a gear to which the data amount in the second configuration period belongs and a resource corresponding to the gear to which the data amount belongs.

1706, the terminal device performs data transmission with the network device in the second configuration period according to the resource corresponding to the gear to which the data amount of the second configuration period belongs.

It is understood that a similar procedure is also performed in the scenario of the uplink CG type2 and the scenario of the downlink SPS. For example, in combination with the flows in fig. 8 and 15, it can be determined that the resource allocation method shown in fig. 5 and the resource allocation method shown in fig. 10 are combined and applied to the flow in the scene of CG type 2; or in combination with the flows in fig. 9 and 16, it may be determined that the resource allocation method shown in fig. 5 and the resource allocation method shown in fig. 10 are combined, and are applied to the flow in the SPS scenario, which is not described herein.

Fig. 18 is a flowchart of another resource allocation method according to an embodiment of the present application. The resource allocation method is realized by interaction between the network equipment and the terminal equipment, is mainly applied to the scene of uplink CG type1, and realizes more flexible resource allocation under the condition of avoiding increasing DCI overhead. The method comprises the following steps:

1801, the terminal device sends data volume information to the network device; correspondingly, the network device receives data volume information from the terminal device. The data volume information comprises data volume corresponding to data arrival time, and the data volume information is used for determining time-frequency domain resources corresponding to each resource configuration period.

The network device determines 1802 resources configured per resource configuration period.

The resource configuration period is a first configuration period or a second configuration period. Descriptions of the first configuration period, the second configuration period, and the resources configured by the resource configuration period refer to corresponding descriptions in the embodiments of fig. 5 and fig. 10, and are not repeated herein.

1803, the network device sends the resources configured in each resource configuration period to the terminal device; correspondingly, the terminal device receives the resources configured for each resource configuration period from the network device.

For example, the network device indicates the resources configured per resource configuration period through the RRC indication message. Since the related parameters (such as time domain offset, time domain allocation, frequency domain allocation, etc.) of the TDRA and the FDRA in the configured grant configuration of the RRC at present can only be configured with one resource, if multiple resources are to be configured, the related parameters of the TDRA and the FDRA need to be extended. For example, a simple extension method is to configure a configuration list (RRC configlist) that includes up to Z ConfiguredGrantConfig. Wherein, Z may be set to be the same as the length of the data volume vector reported by the terminal, or set to be a fixed value according to the service type. Wherein each configurable GrantConfig comprises one or more of the following: timedomainoffset, timeDomainAllocation and frequencydomaimatillation. If a certain information (such as time domain offset or time domain allocation or frequency domain allocation) is not configured, the value of the unconfigured information is the same as the value of the corresponding information configured by the last configured grantconfig. For another example, another extension method is to configure one configurable grantconfigu, which includes Z timedomainoffset, Z timedomainalllocations and Z frequencydomallocations. Wherein Z is determined according to the data amount information, and Z is a positive integer.

1804, the terminal device performs data transmission with the network device according to the resources configured in each resource configuration period.

In an example, fig. 19 is a schematic flow chart of combining CG periodic correction with flexible resource allocation in the scenario of uplink CG type1, and the description in fig. 18 applies to fig. 19, and reference may be made between fig. 18 and fig. 19. The method is realized by interaction between the network equipment and the terminal equipment, and comprises the following steps:

1901, the terminal device sends data arrival time and data volume information to the network device; correspondingly, the network device receives the data arrival time and data volume information from the terminal device.

1902a, the network device determines resources configured per resource configuration period.

1902b, the network device determines, based on the data arrival time, a CG period (i.e., a first configuration period) satisfying a first relationship or a second relationship with the data arrival time. The network device may also determine a period adjustment parameter based on the data arrival time and the first configuration period.

Note that 1902a and 1902b are not strictly sequential in execution, e.g., 1902a may be executed first and 1902b may be executed second; or, the process 1902b is executed first, followed by the process 1902a; or 1902a and 1902b are performed simultaneously.

1903, the network device sends an RRC indication message to the terminal device, indicating the first configuration period and the time-frequency domain resources configured by the first configuration period; correspondingly, the terminal device receives the RRC indication message from the network device.

Alternatively, step 1903 may be replaced with step 1903a, where the network device determines a second configuration period (i.e., a corrected CG period) based on the first configuration period and the period adjustment parameter of the first configuration period. The network device sends an RRC indication message to the terminal device, where the RRC indication message is used to indicate the second configuration period and the time-frequency domain resources configured by the second configuration period.

1904, the terminal equipment determines a second configuration period according to the first configuration period and the data arrival time; alternatively, the terminal device directly receives the second configuration period.

And 1905, the terminal equipment performs data transmission with the network equipment according to the time-frequency domain resources configured in the second configuration period.

It can be seen that, through the steps in the above flow, the terminal device can implement correction of CG period, and flexible scheduling of time-frequency domain resources can be implemented in the corrected CG period. It should be noted that, the specific implementation manner of the above steps may refer to the corresponding descriptions in the embodiments of fig. 5 and 10, and will not be repeated here.

The embodiment of the application provides a resource allocation method, wherein network equipment can directly indicate corresponding resources for each resource allocation period respectively, so that the network equipment and terminal equipment perform data transmission according to the resources corresponding to each resource allocation period respectively. The method realizes flexible scheduling of CG resources without increasing DCI configuration overhead, and is beneficial to adapting to services with larger data volume dynamic range.

Fig. 20 is a flowchart of another resource allocation method according to an embodiment of the present application. The resource allocation method is executed by the network equipment and comprises the following steps:

2001, the network device determines a result of the ranking of the data amount from the data amount information.

2002, the network equipment determines a gear identifier, a configuration period corresponding to the gear identifier and a resource corresponding to the gear identifier according to the data quantity grading result and the data arrival time.

Note that in the scenario of upstream data transmission, before step 2001, the steps are further included: the network device receives data volume information and data arrival time from the terminal device. In other words, in the uplink data transmission scenario, the network device receives the data amount information and the data arrival time first, and can grade the data amount according to the data amount information, and determine the grading result of the data amount, thereby determining the gear identifier, the configuration period corresponding to the gear identifier, and the resource corresponding to the gear identifier. In the downlink data transmission scenario, the network device is used as a data sender, knowing the data quantity information and the data arrival time to be sent, and the network device can directly determine the data quantity grading result according to the data quantity information and the data arrival time, so as to determine the gear identifier, the configuration period corresponding to the gear identifier and the resource corresponding to the gear identifier.

Wherein the data volume information comprises data volumes of different data arrival times, and in particular, the data volume information can be expressed in the form of data volume vectors. For example, the data amount vector of the data arrival time is s= [ s ] ₀ ,s ₁ ,...,s _N-1 ]. The data amount vector may refer to the corresponding description in the embodiment of fig. 10, and will not be described herein.

The result of the shift of the data amount may be one or more of the number of shifts or the reference data amount or the shift position to which the data amount belongs, as in the foregoing embodiment. Reference may be made specifically to the foregoing embodiments, and details are not repeated here.

In particular, the network device may determine the result of the data size classification according to the data size classification method described in the embodiment of fig. 10. Specific steps may refer to corresponding descriptions in the embodiment of fig. 10, and are not repeated here.

Specifically, the network device determining the gear identification according to the data amount of the gear result includes: the network device is according to the gear vector l= [ l ] ₀ ,l ₁ ,...,l _N-1 ]Each data amount of the range l _i Determining a value of (2) a gear shiftAnd (5) identifying. That is, the network device regards or defines the data amounts belonging to the same gear as a group based on the result of the gear shift of the data amounts, and uses or determines a uniform gear identification for this group of data amounts. For example, let l= [ l ] ₀ ,l ₁ ,l ₂ ,l ₃ ]＝[1,0,0,2]Wherein l is ₁ ＝l ₂ =0 represents the data amount s ₁ Sum s ₂ The associated gear in the gear result is the 0 th gear, and correspondingly, the data quantity s can be calculated ₁ Sum s ₂ Setting a gear mark to be 0; l (L) ₀ =1 represents the data amount s ₀ The associated gear in the gear result is the 1 st gear, correspondingly, the data quantity s can be calculated ₀ Setting the gear mark as 1, l ₃ =2 represents the data amount s ₃ The gear belonging to the gear step result is the 2 nd gear, and correspondingly, the data quantity s can be obtained ₃ The gear mark is set to 2. Of course, the gear position identification may not coincide with the associated gear position in the result of the gear position division of the data amount, e.g. the data amount s ₀ Setting the gear mark as 0, and setting the data quantity s ₁ Sum s ₂ Setting the gear mark as 1, and setting the data quantity s ₃ The gear mark is set to be 2, and the application is not limited.

Further, the network device may determine, according to the data amount information, the data arrival time, and the gear identifier, a configuration period corresponding to the gear identifier. For example, the data arrival time may be the actual arrival time of the data period or the aperiodic rule for which an approximate data period may be determined. For example, the data amount vector shown in FIG. 21 includes 7 data (one data for each data arrival time), where the 0 th data arrival time t ₀ Gear position=0 is identified as 0 th gear, 1 st data arrival time t ₁ ＝T _P The gear of (2) is identified as gear 2, the 2 nd data arrival time t ₂ ＝2T _P The gear of (1 st gear) and the 3 rd data arrival time t ₃ ＝3T _P The gear of (2) is identified as the 2 nd gear, the 4 th data arrival time t ₄ ＝4T _p The gear of (2) is identified as the 0 th gear, the 5 th data arrival time t ₅ ＝5T _p The gear mark is 2File, 6 th data arrival time t ₆ ＝6T _p The gear of (2) is identified as 1 st gear. From the 7-group data amount and the shift position identification thereof shown in FIG. 21, it can be determined that the period of the 0 th shift position data is 4T _p The period of the 1 st data is 4T _p The period of the 2 nd data is 2T _p . That is, the network device may determine that the data period of the 0 th data is 4T _p The data period of the 1 st data is 4T _p The data period of the 2 nd data is 2T _p . If the configurable CG/SPS cycle range includes the data cycle 4T of the 0 th data _p Data period 4T of 1 st data _p And data period 2T of 2 nd data _p The network device determines that the configuration period of the 0 th data is 4T _p The configuration period of the 1 st data is 4T _p The configuration period of the 2 nd data is 2T _p . If the configurable CG/SPS period does not include the data period corresponding to the different gear identification data, the network device selects, from the configurable CG/SPS period, the CG/SPS period that satisfies the first relationship or the second relationship with the data period, that is, takes the first configuration period as the configuration period corresponding to the different gear identification. Alternatively, the period adjustment or correction may be performed based on the first configuration period and the data period to obtain a second configuration period matched with the data period, and the second configuration period is used as the configuration period corresponding to the different gear identifiers. It should be noted that, here, taking the case where the arrival time of the data corresponding to the gear identifier has a periodic rule as an example, in some cases, the arrival time of the data corresponding to a certain gear identifier has no periodic rule, for example, the arrival time corresponding to each data amount with a gear identifier of 0 is respectively T _P ,3T _P ,6T _P ,7T _P In this case, the mean of the differences between adjacent arrival times can be taken as an approximate data period (e.g., here 2T _P ) And determining a directly available configuration period or a first configuration period or a second configuration period according to the comparison of the approximate data period and the configurable CG/SPS period. Wherein the most difference between adjacent arrival times can also be takenThe difference between the small or maximum value or the first adjacent arrival time is used as an approximate data period and is not limited in this application.

Further, the network device may determine, according to the data amount vector and the gear identifier, a resource corresponding to the gear identifier. For example, suppose that the data amount of the 0 th-gear data varies from 0bit to 1×10 ² bit, 1 st data amount change range is 1×10 ² bit to 1 x 10 ⁴ bit, 3 rd data amount change range is 1×10 ⁴ bit to 1 x 10 ⁸ bit. The network device may determine the time-frequency domain resources (i.e., the resources corresponding to the gear identification) required for transmitting each gear data according to the variable range of the data amount of each gear data and the available time-frequency domain resources.

2003, the network device sends the data amount of the step result, the gear identifier, the configuration period corresponding to the gear identifier and the resource corresponding to the gear identifier to the terminal device.

Alternatively, in the downlink data transmission scenario, the network device may not send the data amount of the grading result, but send the data amount information, and the terminal device may determine the data amount of the grading result according to the data amount information, and the specific method may refer to the foregoing embodiment, which is not described herein in detail.

For example, in the CG type 1 scenario, the network device indicates, through RRC, the gear identifier, a configuration period corresponding to the gear identifier, and a time-frequency domain resource corresponding to the gear identifier. For another example, in the CG type 2 or SPS scenario, the network device indicates, through RRC, a configuration period corresponding to the gear identifier and indicates, through DCI, a time-frequency domain resource corresponding to the gear identifier. The manner of indicating the result of the stepping of the data amount may refer to the foregoing embodiment.

In one possible implementation, if the data arrival time corresponding to a certain gear identifier matches a certain period of the configurable CG/SPS periods, the configuration period corresponding to the gear identifier is the CG/SPS period that matches the data arrival time.

In one possible implementation, the configuration period corresponding to the gear identifier is a first configuration period in the configurable CG/SPS period that satisfies a first relationship with the data arrival time, and the first configuration period may be a minimum CG/SPS period that is greater than the data arrival time among the configurable CG/SPS periods when one or more CG/SPS periods exist in the configurable CG/SPS period that is greater than the data arrival time. Or the configuration period corresponding to the gear identification is a first configuration period of which the configurable CG/SPS period and the data arrival time meet a second relation, and the first configuration period is the maximum CG/SPS period in the configurable CG/SPS period when the configurable CG/SPS period is smaller than the data arrival time.

It should be noted that, when the configuration period corresponding to the gear identifier is a first configuration period in which the configurable CG/SPS period and the data arrival time satisfy the first relationship or the second relationship, if the first configuration period needs to be modified, the network device further needs to send the data arrival time or the period modification parameter to the terminal device, and the specific description may refer to the embodiment of period modification in fig. 5, which is not described herein. Alternatively, the configuration period corresponding to the gear identifier may be a modified second configuration period, in which case the network device does not need to send the data arrival time or the period modification parameter to the terminal device any more, but directly sends the second configuration period.

The embodiment of the application provides a resource allocation method, in which network equipment performs grading on data quantity of each data arrival time, determines a grading result of the data quantity, and further determines a gear identifier, a allocation period corresponding to the gear identifier and a resource corresponding to the gear identifier. Therefore, each data is respectively configured with one set of SPS/CG, and flexible configuration of SPS/CG resources is realized according to the change of the data quantity.

The specific flow of the resource allocation method shown in fig. 20 applied to the uplink allocation grant scenario or the downlink semi-static scheduling scenario is described below.

Fig. 22 is a flowchart illustrating the application of the resource allocation method shown in fig. 20 to the scenario of uplink CG type1 or CG type2, and the description in fig. 20 is applicable to fig. 22, and reference may be made between fig. 20 and fig. 22. The process is realized by interaction between the network equipment and the terminal equipment, and comprises the following steps:

in the uplink CG type1 scene:

2201a, a terminal device sends data volume information and data arrival time to a network device; correspondingly, the network device receives the data volume information and the data arrival time from the terminal device. Wherein the data volume information includes a data volume of a data arrival time.

2202a, the network device determines a result of the ranking of the data amount from the data amount information.

2203a, determining, by the network device, a gear identifier, a configuration period corresponding to the gear identifier, and a resource corresponding to the gear identifier according to the data amount of the data amount.

2204a, the network device sends an RRC indication message to the terminal device, where the RRC indication message is used to indicate a gear identifier, a configuration period corresponding to the gear identifier, and a resource corresponding to the gear identifier; correspondingly, the terminal device receives the RRC indication message from the network device.

Taking the data amount grading result as an example, specifically, if the network device and the terminal device adopt the same preset grading number to grade the data amount, the network device does not need to send the data amount grading result to the terminal device, and only needs to send the gear identifier, the configuration period corresponding to the gear identifier and the resource corresponding to the gear identifier. If the network device and the terminal device do not adopt the preset number of steps to step the data volume, the network device also needs to send the number of steps to the terminal device when sending the step identifier, the configuration period corresponding to the step identifier and the resource corresponding to the step identifier to the terminal device. For example, the network device indicates the number of steps by adding a parameter numDataSizeLevel to the configured gradtconfigure of RRC, which is used to indicate the gear identification. It should be noted that, the network device may also indicate other parameters through RRC signaling, and the specific implementation is completed according to the existing CG configuration manner, which is not limited in this embodiment.

In the uplink CG type2 scene:

2201b, the terminal device sends data volume information and data arrival time to the network device; correspondingly, the network device receives the data volume information and the data arrival time from the terminal device. Wherein the data volume information includes a data volume of a data arrival time.

2202b, the network device determines a result of the ranking of the data amount from the data amount information.

2203b, determining, by the network device, a gear identifier, a configuration period corresponding to the gear identifier, and a resource corresponding to the gear identifier according to the data amount of the data amount.

2204b, the network device sends an RRC indication message and a DCI indication message to the terminal device, where the RRC indication message is used to indicate a gear identifier and a configuration period corresponding to the gear identifier, and the DCI indication message is used to indicate a resource corresponding to the gear identifier; correspondingly, the terminal device receives the RRC indication message from the network device.

It should be noted that 2201a and 2201b (or 2202a and 2202b, or 2203a and 2203b, or 2204a and 2204 b) are juxtaposed method steps, e.g., in an upstream CG type1 scenario, the network device and the terminal device perform steps 2201a-2204a; in the upstream CG type1 scenario, the network device and the terminal device perform steps 2201b-2204b.

Further, steps 2205 and 2206 are also included:

and 2205, the terminal equipment determines the gear identification matched with each data volume according to the data volume grading result.

It will be appreciated that the terminal device may complete the data volume to obtain the data volume result by itself, or may receive the data volume result from the network device, and the specific process and possible implementation may refer to the foregoing embodiments, which are not described in detail herein.

And 2206, the terminal equipment performs data transmission with the network equipment according to the configuration period corresponding to the matched gear identification and the resource corresponding to the matched gear identification.

For example, for the data amount of the data arrival time as shown in FIG. 21, for the period 4T of the 0 th data _p The period of the 1 st data is 4T _p The period of the 2 nd data is 2T _p . The terminal device determines t=0 and t=4t _P Time of dayThe shift position matched with the data amount of the data is identified as 0 th shift position, and the data amount is set to be 4T according to the corresponding configuration period of the 0 th shift position _p And carrying out data transmission on the time-frequency domain resources corresponding to the 0 th gear and the network equipment. Determining t=2t _P And t=6t _P The gear position matched with the data amount at the moment is identified as 1 st gear, and the gear position is set to be 4T according to the corresponding configuration period of 1 st gear _p And carrying out data transmission on the time-frequency domain resources corresponding to the 1 st gear and the network equipment. Determining t=t _P 、t＝3T _P And t=5t _P The gear position matched with the data amount at the moment is identified as the 2 nd gear, and the gear position is configured according to the corresponding configuration period of the 2 nd gear, such as 2T _p And carrying out data transmission on the time-frequency domain resources corresponding to the 2 nd gear and the network equipment.

Optionally, step 2206 is for an i-th configuration period iP, i=0, 1..m-1; however, based on the characteristic of CG periodicity, for the i+nm configuration period, n is a positive integer, and before CG period fails or is reconfigured, the network device and the terminal device may use the resources corresponding to the matched gear identifier in the i+nm configuration period. For example, at t= (i+nn) ×4t _P The shift position matched with the data amount at i=0, 1, 2..moment is identified as 0 th shift, and the configuration period 4T corresponding to the 0 th shift is set according to the configuration period of the 0 th shift _p And carrying out data transmission on the time-frequency domain resources corresponding to the 0 th gear and the network equipment.

In one example, the staging of the data volume is done by the terminal device, rather than by the network device. In this case, the terminal device determines a result of the data amount being shifted, and when the result of the data amount being shifted is the number of shifts (i.e., the number of shifts is not preset), the terminal device transmits the data amount information, the data arrival time, and the number of shifts to the network device. And the network equipment determines the gear identification, the configuration period corresponding to the gear identification and the resource corresponding to the gear identification according to the data quantity information, the data arrival time and the number of steps. And when the data quantity is classified into the gear to which the data quantity belongs, the terminal equipment sends the data arrival time and the gear to which the data quantity belongs to the network equipment. And the network equipment determines the gear identification, the configuration period corresponding to the gear identification and the resource corresponding to the gear identification according to the data arrival time and the gear to which the data quantity belongs. The other steps are similar to those in fig. 22 and will not be described again here.

In yet another example, the data amount is classified by the terminal device, and the terminal device determines a classification result of the data amount and a gear identifier, for example, the classification result of the data amount is a classification number (i.e. the classification number is not preset), and the terminal device needs to send a data arrival time, data amount information and the gear identifier to the network device, where the data arrival time may be a data period or an approximate data period of data corresponding to each gear identifier. And the network equipment determines a configuration period corresponding to the gear identifier and resources corresponding to the gear identifier according to the data arrival time, the data quantity information, the gear grading result of the data quantity and the gear identifier. The other steps are similar to those in fig. 22 and will not be described again here.

Optionally, if the configuration period corresponding to the gear identifier is the first configuration period, the first configuration period may be modified to obtain the second configuration period in a manner of the foregoing embodiment, and the specific process is not described herein, which may refer to the foregoing embodiment.

Fig. 23 is a schematic flow chart of the resource allocation method shown in fig. 20 applied in a downlink SPS scenario, and the related description in fig. 20 applies to fig. 23, and reference may be made between fig. 20 and fig. 23. The process is realized by interaction between the network equipment and the terminal equipment, and comprises the following steps:

2301, the network device sends data volume information to the terminal device; correspondingly, the terminal device receives data volume information from the network device. Wherein the data amount information includes the data amount of the data arrival time (e.g., the data vector in the foregoing embodiment).

2302, the network device determines a ranking result of the data volume according to the data volume information.

2303, the network device determines the gear identifier, the configuration period corresponding to the gear identifier, and the resource corresponding to the gear identifier according to the data amount of the grading result and the data arrival time.

2304, the network device sends an RRC indication message to the terminal device, where the RRC indication message is used to indicate the gear identifier and a configuration period corresponding to the gear identifier; correspondingly, the terminal device receives the RRC indication message from the network device.

2305, the network device sends a DCI indication message to the terminal device, where the DCI indication message is used to indicate a resource corresponding to the gear identifier; correspondingly, the terminal device receives the DCI indication message from the network device.

2306, the terminal device determines the gear identifier matched with each data volume according to the data volume grading result.

2307, the terminal device performs data transmission with the network device according to the configuration period corresponding to the matched gear identifier and the resource corresponding to the matched gear identifier.

It can be understood that the implementation mode corresponds to that the terminal equipment firstly determines the gear to which the data quantity belongs according to the data quantity information, and then determines the gear identification. Various implementation manners related to determining, by the terminal device, the gear to which the data amount belongs according to the data amount information may refer to the foregoing embodiments, which are not described in detail herein.

In one example, the staging of the data volume is done by the terminal device, rather than by the network device. For example, the terminal device receives data amount information from the network device, and determines a data amount classification result, such as a gear to which the data amount belongs, according to the data amount information; the terminal equipment sends the data quantity grading result to the network equipment, and the network equipment receives the data quantity grading result correspondingly; the network device directly determines the gear identifier, the configuration period corresponding to the gear identifier and the resource corresponding to the gear identifier according to the data quantity of the gear result, and other steps are similar to those in fig. 23, and are not repeated here.
