Description

Resource pool configuration method and device

The present application claims priority from chinese patent application filed on 2017, 13/07/78 under the name of "a method and apparatus for data transmission in a wireless communication system" by the chinese patent office, application No. 201710570772.2, the entire contents of which are incorporated herein by reference.

Technical Field

The present application relates to the field of communications, and in particular, to a resource pool configuration method and apparatus.

Background

In a Long Term Evolution (LTE) communication system, when a terminal device sends data to a network device, a data transmission mode based on authorization is usually adopted. In the data transmission mode based on authorization, before transmitting uplink data, the terminal device needs to perform multiple rounds of signaling interaction with the network device, so as to obtain dedicated resources required for transmitting the uplink data from the network device side, that is, obtain authorization. The terminal equipment transmits the uplink data on the special resource, so that the data transmission is free from interference and has higher reliability. However, multiple rounds of signaling interaction between the terminal device and the network device are required, which takes a long time, and in the multiple rounds of signaling interaction, more information is transmitted, and the process of analyzing the information content between the terminal device and the network device also takes a long time.

In order to solve the problems of long time consumption and long time delay in the data transmission mode, a fifth generation mobile communication system (5)^thGeneration, 5G) proposes a Grant-free (Grant-free) uplink data transmission scheme, and the Grant-free is mainly applied to Ultra Reliable Low Latency Communication (URLLC) service in 5G. In an authorization-free uplink data transmission mode, a network device configures a resource pool for a plurality of terminal devices, and when data needs to be transmitted, the terminal devices do not need to request a base station for transmission resources adopted in uplink transmission, but select the transmission resources from the pre-configured resource pool to directly transmit the uplink data, thereby reducing the delay of data transmission.

However, there is a possibility of collision when a plurality of terminal devices compete for transmission resources in the resource pool, so that the reliability is reduced while the benefit of low latency is brought about by the unlicensed transmission. To compensate for reliability, a common processing method is to configure a larger resource pool for a terminal device, so as to avoid collision among multiple terminal devices. However, the data volume of the URLLC service in 5G is uncertain, and if the resource pool is too large and the data volume of the actual URLLC service is small, resource waste may be caused.

Detailed Description

The network architecture and the service scenario described in the embodiment of the present application are for more clearly illustrating the technical solution of the embodiment of the present application, and do not form a limitation on the technical solution provided in the embodiment of the present application, and as a person of ordinary skill in the art knows that along with the evolution of the network architecture and the appearance of a new service scenario, the technical solution provided in the embodiment of the present application is also applicable to similar technical problems.

A possible network architecture of an embodiment of the present application is described below with reference to fig. 1. Fig. 1 illustrates a network architecture to which embodiments of the present application may be applied. As shown in fig. 1, the network architecture provided by the present embodiment includes a network device 10 and at least one terminal device 20.

The network device 10 is a device for accessing the terminal device to the wireless network, and may be an evolved Node B (eNB or eNodeB) in an LTE communication system, or a relay station or an access point, or a base station in a future 5G network, or a macro base station, a micro base station, a hot spot, a home base station, a transmission point, and the like, which is not limited herein. Fig. 1 schematically illustrates a possible example, which is illustrated by taking the network device as a base station.

Terminal device 20 may be a wireless terminal, which may be a device that provides voice and/or other traffic data connectivity to a user, a handheld device having wireless connection functionality, or other processing device connected to a wireless modem. A wireless terminal, which may be a mobile terminal such as a mobile phone (or "cellular" phone), a notebook computer, a bracelet, a smart watch, a data card, a sensor, and a computer having a mobile terminal, for example, a portable, pocket, hand-held, computer-included, or vehicle-mounted mobile device, may communicate with one or more core networks via a Radio Access Network (RAN), and may exchange language and/or data with the RAN. For example, devices such as Personal Communication Service (PCS) phones, cordless phones, Session Initiation Protocol (SIP) phones, Wireless Local Loop (WLL) stations, and Personal Digital Assistants (PDAs) are used. The wireless Terminal may also be referred to as a system, a Subscriber Unit (Subscriber Unit), a Subscriber Station (Subscriber Station), a Mobile Station (Mobile), a Remote Station (Remote Station), a Remote Terminal (Remote Terminal), an Access Terminal (Access Terminal), a User Terminal (User Terminal), and a User Agent (User Agent), which are not limited herein. Fig. 1 schematically depicts a possible illustration, which is shown by way of example of the terminal device being a mobile telephone. Illustratively, for a network architecture in which a sidelink exists, such as bracelet-handset-base station, the bracelet may also be considered as terminal device 20 and the handset as a network device.

In the LTE communication system, when a terminal device transmits data to a network device, a data transmission method based on authorization is usually adopted. In the data transmission mode based on authorization, before transmitting uplink data, the terminal device needs to perform multiple rounds of signaling interaction with the network device, so as to obtain dedicated resources required for transmitting the uplink data from the network device side, that is, obtain authorization. The network equipment transmits uplink data on the special resource, so that interference can be avoided, and the transmission reliability is ensured.

However, with the development of communication technology, the 5G technology gradually replaces the LTE technology. The main services in 5G include enhanced Mobile broadband (eMBB) service, URLLC service, and large Machine Type Communication (mtc) service. The eMBB service refers to an enhanced mobile broadband service, such as a service that accesses the internet using mobile phone traffic. The URLLC service is an ultra-reliable low-delay service, such as industrial control, etc., and the URLLC service is characterized by high requirements on delay and reliability of data transmission. The mtc service refers to a large-scale machine communication service in which an intelligent device connects to the internet without human intervention, and performs communication automatically, for example, an intelligent meter reading service, and an electric meter reports data automatically and periodically.

URLLC service in 5G puts high demands on the speed of data transmission. In a data transmission mode in an LTE communication system, multiple rounds of signaling interaction are required between a terminal device and a network device. In the multi-round signaling interaction process, more information is transmitted, the information needs to be carried in the high-level signaling for sending, and the time consumption of the process of analyzing the information from the high-level signaling by the terminal equipment and the network equipment is long. Therefore, the process of obtaining the authorization by the terminal device in the LTE communication system is delayed. Therefore, the data transmission mode in the LTE communication system cannot meet the requirement of URLLC service on the data transmission speed.

In order to solve the problems of long time consumption and long time delay of a data transmission mode in an LTE communication system, an authorization-free uplink data transmission mode is provided in 5G. In an authorization-free uplink data transmission mode, a network device configures a resource pool for a plurality of terminal devices, and when data needs to be transmitted, the terminal devices do not need to request a base station for dedicated resources used in uplink transmission, but select transmission resources from the pre-configured resource pool to directly transmit the uplink data, thereby reducing the delay of data transmission. However, there is a possibility of collision when a plurality of terminal devices compete for transmission resources in the resource pool, so that the reliability is reduced while the benefit of low latency is brought about by the unlicensed transmission.

To compensate for reliability, a common processing method is to configure a larger resource pool for a terminal device, so as to avoid collision among multiple terminal devices. However, the data volume of the URLLC service in 5G is uncertain, and if the resource pool is too large and the data volume of the actual URLLC service is small, resource waste may be caused, and the available resources of the eMBB service and the mtc service are also affected.

In order to solve the problem of resource waste caused by a large resource pool, in an embodiment of the present application, before data Transmission is performed, each terminal device sends a Grant Free Transmission Request (GFTR) to a network device, so that the network device generates Grant Free Transmission resource (GFTA) information according to the received GFTR and sends the GFTA information to the terminal device, where the GFTA information indicates a resource pool configured for the terminal device by the network device. Therefore, the resource pool adopted by the terminal device during the unauthorized transmission is dynamically configured by the network device according to the received GFTR, so that the size of the resource pool is related to the quantity of the data to be transmitted, and the problem of resource waste caused by the overlarge resource pool is avoided.

The resource pool configuration method provided by the present application is described in detail below with reference to specific embodiments. In the following several embodiments, the same or similar concepts or processes may not be described in detail in some embodiments.

Fig. 2 is a schematic signaling flow diagram of a resource pool configuration method according to an embodiment of the present application. The execution subject of the method is a network device and at least one terminal device. The embodiment relates to a specific process that a network device receives a GFTR sent by at least one terminal device and configures a resource pool for the terminal device according to the received GFTR. As shown in fig. 2, the method includes:

s201, the terminal device sends GFTR to the network device.

The GFTR is used for indicating the terminal equipment to have uplink data to be transmitted to the network equipment.

Illustratively, when there is uplink data to be sent at the terminal device, the terminal device sends a GFTR to the network device. When a plurality of terminal devices have uplink data to be sent, the plurality of terminal devices all send GFTR to the network device. Referring to fig. 2, when uplink data to be sent exists in both terminal device 1 and terminal device 2, both terminal device 1 and terminal device 2 send GFTR to the network device. The GFTR is used for indicating the terminal equipment to have uplink data to be transmitted to the network equipment. Alternatively, the GFTRs of different terminal devices may be the same. Alternatively, the GFTR may be transmitted at the physical layer.

S202, the network equipment receives the GFTR sent by at least one terminal equipment and generates GFTA information according to the GFTR.

The GFTA information is used for indicating a resource pool adopted by the terminal equipment during the unauthorized transmission.

Illustratively, the network device receives a GFTR sent by at least one terminal device, and when the network device receives the GFTR, it indicates that there is a terminal device that needs to send uplink data. When the network device receives a plurality of GFTRs, the network device may determine that there are a plurality of terminal devices having data to be transmitted upstream. Therefore, the network device can determine how much uplink data to be sent exists on the terminal device according to the received GFTR, so as to allocate a resource pool to the terminal device according to the amount of the uplink data to be sent. Optionally, the GFTR may be used only to indicate that there is data to be transmitted, and does not need to carry the identifier of the terminal device that sent the GFTR, so that the amount of information in the GFTR is small, and the transmission speed of the GFTR can be increased. Correspondingly, the network device does not need to determine which terminal device has the uplink data to be transmitted according to the GFTR, and only determines how much uplink data to be transmitted exists according to the received GFTR, so as to generate GFTA information according to the amount of the uplink data to be transmitted, so that the configuration of the authorization-free resource pool is related to the amount of the data to be transmitted. For example, when the amount of data to be transmitted is large, a large resource pool can be configured to avoid reduction of transmission reliability caused by contention, and when the amount of data to be transmitted is small, a small resource pool can be configured to avoid waste of resources in the resource pool. Therefore, the resource pool configuration method provided by the embodiment is more reasonable.

Optionally, the GFTA information includes size information and/or location information of the resource pool. Illustratively, in order to partition the resource pool on the time-frequency resources, the GFTA information includes at least one of the number of symbols occupied by the resource pool, the number of start symbols, and the number of stop symbols, and at least one of the start subcarrier information, the subband width information, and the stop subcarrier information occupied by the resource pool. For example, the network device may send the start and end frequency domain resources and the start and end time domain resources occupied by the resource pool to the terminal device, thereby defining the resource pool. The network device may also send the frequency domain bandwidth and the time domain width occupied by the resource pool to the terminal device, and determine the resource pool according to the starting subcarrier information/the terminating subcarrier information, the starting symbol number/the terminating symbol number of the resource pool preset by the terminal device.

The resource pool indicated by the GFTA information includes at least one Grant Free Transmission Uint (GFTU). After receiving the GFTA information sent by the network device, the terminal device selects a GFTU from the GFTA information for uplink data transmission. Illustratively, the GFTU may be a basic resource unit of a terminal device in uplink data transmission, or a resource block formed by several basic resource units. One basic resource unit is uniquely determined by a time domain starting point, a time domain length, a frequency domain starting point, and a frequency domain width. The basic resource unit can also be defined as resources in other dimensions in an expanded manner, for example, if a Sparse Code Multiple Access (SCMA) technique is used for uplink data transmission, the definition of the basic resource unit can also be extended to a Code domain, that is, the basic resource unit is defined as a combination of time-frequency resources and Code domain resources. Illustratively, for SCMA, a basic resource unit is defined as a combination of time-frequency resources, SCMA codebook and pilot sequences. Optionally, the GFTU may be a time-frequency resource block defined by frequency domain and time domain parameters, or a resource unit defined by frequency domain, time domain and code domain parameters. In the case where the code-domain parameters define a GFTU, different GFTUs may partially or fully overlap in the frequency and/or time domain. For convenience of description, in the following embodiments of the present application, a basic resource unit is described as a time-frequency resource block as an example, but it is easily understood that all embodiments of the present application can be applied to a case where the basic resource unit adopts other definitions.

S203, the network device sends GFTA information to each terminal device.

Illustratively, the network device generates GFTA information from the GFTR and transmits the GFTA information to the terminal devices. Illustratively, the network device broadcasts GFTA information.

In the resource pool configuration method provided by the embodiment of the application, the terminal device sends the GFTR to the network device, and the GFTR is used for indicating the network device that the terminal device has uplink data to be transmitted; the network equipment receives the GFTR sent by at least one terminal equipment and generates GFTA information according to the GFTR; and the network equipment sends the GFTA information to each terminal equipment, wherein the GFTA information is used for indicating a resource pool adopted by the terminal equipment when the terminal equipment carries out the authorization-free transmission. In the resource pool configuration method provided by this embodiment, before performing uplink data transmission, the terminal device sends the GFTR to the network device to obtain GFTA information generated by the network device according to the GFTR, where the GFTA information indicates a resource pool used by the terminal device when the terminal device is not authorized to transmit, and the resource pool indicated in the GFTA information is obtained by the network device according to the received GFTR, so that the size of the resource pool is configured according to the amount of data to be sent, and therefore, when the amount of data is small, resource waste caused by configuring a large resource pool can be avoided, and problems of increased contention and reduced reliability of data transmission caused by too small configured resource pool can be avoided. The embodiment of the application provides a dynamic resource pool configuration method, and the resource pool configuration is more reasonable.

Further, on the basis of the embodiment shown in fig. 2, the embodiment of the present application further provides a resource pool configuration method, and in this embodiment, in order to ensure that the network device correctly receives the GFTR, details of the sending and receiving timings of the GFTR are described. Fig. 3 is a schematic signaling flow diagram of a resource pool configuration method according to a second embodiment of the present application. As shown in fig. 3, a resource pool configuration method provided in the embodiment of the present application includes:

s301, the terminal device sends GFTR to the network device on a first preset resource in a first time slot.

The first preset resource occupies part of the resources in the uplink time-frequency resource corresponding to the first time slot.

In a communication system, a terminal device and a network device occupy a certain time and bandwidth when transmitting information, and all the time and bandwidth occupied by the information are called time-frequency resources. The time-frequency resources are divided in the time domain by a radio frame (radio frame). One radio frame includes 10 subframes (subframes), each having a time length of 1 millisecond (ms). In the LTE communication system, each subframe includes two slots (slots), and the time length of each slot is 0.5 ms. The number of OFDM symbols included in each slot is related to the Cyclic Prefix (CP) length in the subframe. If the CP is normal CP, each slot includes 7 OFDM symbols, and the time length of each OFDM symbol is about 71.4 μ s, for example, each slot is composed of OFDM symbols with sequence numbers #0, #1, #2, #3, #4, #5, # 6. If the CP is an extended CP, each slot includes 6 OFDM symbols, for example, each slot is composed of OFDM symbols with sequence numbers #0, #1, #2, #3, #4, # 5. In the following embodiments of the present application, the resource pool configuration method provided by the present application is described in detail only that each slot includes 7 OFDM symbols. The minimum unit of the time-frequency resource on the frequency domain is a subcarrier, the width of each subcarrier (subcarrier) is 15KHz, the subcarriers distributed in the time range corresponding to one OFDM symbol form the frequency domain resource corresponding to the OFDM symbol, and the frequency domain resources corresponding to all the OFDM symbols form the time-frequency resource.

In order to flexibly support multiple service characteristics, the width of the sub-carrier is not limited in the embodiment of the present application. The length of an OFDM symbol may be shorter as the subcarrier is wider, and thus more slots may be included in one subframe while the time length of the subframe remains unchanged. For example, when the subcarrier width is changed from 15KHz to 30KHz, the length of the OFDM symbol is about 35.7 microseconds. A subframe may have 4 slots if 7 OFDM symbols are still used as a slot. When the width of the subcarrier is 60KHz, the length of the OFDM symbol is further shortened by a half compared with that when the width of the subcarrier is 30KHz, and by taking 7 OFDM symbols as a time slot, 8 time slots can be formed in one subframe. If a slot is defined to contain 14 OFDM symbols when the subcarrier width is 60KHz, a subframe contains 4 slots instead of 8 slots. For example, fig. 4 shows a subframe structure to which the embodiments of the present application may be applied. As shown in fig. 4, one subframe includes 8 slots, each of which includes 7 OFDM symbols.

Optionally, sending, by the terminal device, information to the network device is referred to as uplink transmission, where a time-frequency resource occupied by the information during the uplink transmission is referred to as an uplink time-frequency resource, sending, by the network device, the information to the terminal device is referred to as downlink transmission, and a time-frequency resource occupied during the downlink transmission is referred to as a downlink time-frequency resource. The uplink time frequency resource and the downlink time frequency resource are not overlapped.

Optionally, the embodiment of the present application further provides at least one time-frequency resource partitioning manner. In the time-frequency resource partitioning manner provided by this embodiment, the time-frequency resources corresponding to the time slot include uplink time-frequency resources and downlink time-frequency resources;

Illustratively, the uplink and downlink division of the time-frequency resources includes two systems, i.e., time division and frequency division. In the frequency division scheme, referring to fig. 4, the uplink time-frequency resource and the downlink time-frequency resource occupy different subcarriers. For example, the frequency domain resources corresponding to the time slots are divided into uplink subcarriers and downlink subcarriers, where the time slots on the uplink subcarriers are all used for uplink transmission, and the time slots on the downlink subcarriers are all used for downlink transmission. Fig. 5 shows another subframe structure to which embodiments of the present application may be applied. For example, fig. 5 shows a subframe structure in a time division scheme, where each slot may have a part of OFDM symbols for uplink transmission and another part of OFDM symbols for downlink transmission. Downlink control information and uplink control information may be transmitted in each slot.

In the time-frequency resource division method provided by the embodiment of the application, the time-frequency resource corresponding to each time slot includes a downlink time-frequency resource and an uplink time-frequency resource. Compared with the method for dividing the subframe into the uplink subframe and the downlink subframe in the LTE communication system, the subframe structure of the embodiment of the application has the advantage that the time interval of uplink and downlink transmission switching is short.

Illustratively, to ensure that the network device can receive the GFTR sent by the terminal device, the network device and the terminal device set a first preset resource at the same position in the time-frequency resource corresponding to each timeslot, for sending and receiving the GFTR. The terminal device may occupy the first predetermined resource in the periodically occurring time slots to send the GFTR to the network device, and correspondingly, the network device periodically receives the GFTR on the first predetermined resource of each time slot. For example, the position of the part of resources on the uplink time-frequency resource corresponding to the first time slot may be a fixed position, and may also be dynamically configured by the network device. The network device may notify the terminal device of the position of the first preset resource in the uplink time-frequency resource corresponding to the first time slot through system broadcast information and a high-level signaling. For example, when the terminal device generates URLLC data to be transmitted, the terminal device may transmit GFTR in the first predetermined resource of the latest first slot. If the terminal device has missed the first predetermined resource in the current time slot, the terminal device can only transmit the GFTR on the first predetermined resource in the next time slot. For example, the first preset resource may occupy all uplink subcarriers corresponding to one or more OFDM symbols in an uplink time-frequency resource corresponding to one timeslot. Alternatively, the first preset resource may occupy all OFDM symbols corresponding to one or more subbands in the uplink time-frequency resource corresponding to one timeslot, where one subband includes at least one subcarrier, as shown in fig. 4. Illustratively, a subband contains 6 or 12 subcarriers.

S302, the network device receives the GFTR sent by at least one terminal device on a first preset resource in a first time slot, and generates GFTA information according to the GFTR.

Illustratively, the network device periodically receives the GFTR on each first preset resource, so that the amount of uplink data to be transmitted can be determined according to the received GFTR. When the network device does not receive the GFTR, it is assumed that no data needs to be transmitted at the current time, and therefore no GFTA information may be generated.

Illustratively, the network device generates the GFTA information according to the GFTR, which may specifically include:

the network equipment acquires the number of GFTRs and generates GFTA information according to the number of the GFTRs.

Further, with reference to the specific embodiment, a detailed description is given below of a manner in which the terminal device sends the GFTR to the network device on the first preset resource in the first time slot, and a manner in which the network device acquires the number of GFTRs.

In a first possible implementation, the first predetermined resource includes at least one GFTR transmitting unit (GFTRU), and the terminal device sends a GFTR to the network device on the at least one GFTR transmitting unit.

Correspondingly, the network equipment acquires the number of the GFTR according to the number of the GFTR transmission units which detect the GFTR in the first preset resource, and generates GFTA information according to the acquired GFTR number.

For example, the first preset resource may include multiple GFTRUs, and a GFTRU occupies little resource, for example, a GFTRU may be a time-frequency resource unit and may occupy at least one to multiple subcarriers in the frequency domain and one OFDM symbol in the time domain, or a GFTRU may be a time-frequency code resource unit and may occupy multiple subcarriers in the frequency domain, for example, 6 or 12 subcarriers, one OFDM symbol in the time domain and one codeword in the code domain. Or, each basic Resource Element (RE) in the first preset Resource serves as a GFTRU, and one RE occupies one subcarrier and one OFDM symbol. The terminal device may transmit the GFTR on at least one GFTRU. For example, the terminal apparatus randomly selects a GFTRU. Illustratively, each terminal device may also be assigned one or more GFTRUs by the network device, where the GFTRUs assigned to different terminal devices are different; or when the number of the GFTRUs is insufficient, the same GFTRU is allocated to a group of terminal devices. In the scheme of allocating GFTRUs, if a terminal device can only use one GFTU during each unlicensed data transmission, the network device only needs to allocate one GFTRU to each terminal device, or the network device allocates one GFTRU to a plurality of GFTRUs of the terminal device, the terminal device can only use one GFTRU to transmit GFTR each time, and the terminal device can only transmit one GFTR each time. If the terminal device can use a plurality of GFTUs each time the unlicensed data transmission is made, a plurality of GFTRUs may be allocated to the terminal device.

For example, the GFTR may only contain 1-bit information, and is only used to indicate that the terminal device has uplink data to be transmitted. When the network device receives the GFTR, it can be considered that there is a terminal device that needs to perform the unlicensed data transmission. The GFTR does not need to carry identification information of the terminal equipment, so that the GFTR occupies less resources. For example, if the carrier bandwidth of the uplink time-frequency resource is 20MHz and the subcarrier width is 60KHz, about 340 subcarriers are included in one carrier, and each RE is taken as a GFTRU as an example, if the first preset resource occupies all the time-frequency resources corresponding to one OFDM symbol, one preset resource may include 340 GFTRUs.

The network equipment receives the GFTR on a first preset resource in a first time slot, detects whether the GFTR exists on each GFTRU or not, counts the GFTR if a GFTR signal is detected, and considers that the GFTR does not exist on the GFTRU if the GFTR signal is not detected. When the network device detects GFTRs on N GFTRUs of the first preset resource, it may determine that there are N terminal devices that need to perform the unlicensed data transmission according to N, or determine that there are N uplink data to be transmitted. Wherein N is a natural number. Illustratively, the GFTA information may be generated based on N and a preset correction factor a, taking into account possible transmission failures or signal overlap. The preset correction coefficient a may be a real number greater than 1, for example, a is at least 1.5, and the number of GFTUs included in the finally determined GFTA may be about the product V of N and a. The size of the GFTA is determined through the detected number N of the GFTRs and the preset correction coefficient a, and the accuracy of transmission resource allocation is improved.

In the implementation mode, each GFTR occupies one GFTRU for sending, so that the network equipment determines the number of the terminal equipment for sending the GFTR according to the number of the detected GFTRs, and meanwhile, the GFTRs contain less information, the speed of detecting whether the GFTRUs are loaded with the GFTRs or not by the network equipment is increased, and the transmission resource configuration speed is increased.

In a second feasible implementation manner, the terminal device sends the GFTR to the network device by using the first power on the first preset resource in the first time slot; the first power is used to make the signal strength when the GFTR of the terminal device reaches the network device a preset power. The first power with which each terminal device transmits GFTR is not necessarily the same.

Correspondingly, the network equipment detects the signal intensity on a first preset resource in a first time slot; and acquiring the number of GFTRs according to the signal strength and the preset power, and generating GFTA information according to the number of the GFTRs.

Illustratively, the transmission of the GFTR may also use an energy approach in order to reduce the amount of resources occupied by the first predetermined resource. The first predetermined resource may occupy only a small number of REs, for example, only 6 consecutive REs constitute the first predetermined resource. The first preset resource is a public resource, and the terminal devices with data to be sent all send GFTR on the public resource. When the terminal device transmits the GFTR, the transmission power of the transmitted GFTR is controlled so that the signal intensity when the GFTR signal reaches the network device side becomes a preset power, that is, a target signal intensity. When a plurality of terminal devices simultaneously send the GFTR on the first preset resource in the first time slot, the target signal strengths of the plurality of GFTRs on the network device side are superposed, and the network device only needs to detect the signal strength pr (recorded as the total strength) of the GFTR on the first preset resource and the target signal strength px (namely, the preset power value) of one GFTR at the network device, so that the number N of the GFTRs superposed on the first preset resource can be determined, and the GFTA information is generated according to the number N.

Illustratively, the GFTR may not contain any digital information, since the network device only needs to detect the signal strength and does not parse the content carried in the GFTR, or the GFTR transmitted by different terminal devices may carry the same 1-bit data. In order to improve the accuracy of generating the GFTA information by the network device, it is necessary to ensure that the signal strength of the GFTR sent by each different terminal device is the preset power px when reaching the network device. Illustratively, the terminal device transmits the GFTR to the network device using the first power. Wherein the first power is used to make the signal strength when the GFTR reaches the network device a preset power px. The terminal device typically generates the first power according to a preset power and a path loss between the terminal device and the network device. For example, since the network device transmits the signal with a fixed strength, the terminal device may listen to the signal transmitted by the network device to estimate the path loss, and the terminal device may estimate the path loss between the terminal device and the network device according to the received power of the signal transmitted by the network device.

Illustratively, when px is-82 dBm and pr is-79 dBm, it can be considered that two terminal devices have sent GFTR or that the network device has detected two GFTR; when pr is-76 dBm, it can be considered that there are four terminal devices transmitting GFTR or that the network device detects 4 GFTR. When a plurality of uplink data to be transmitted exist on one terminal device, the terminal device can adaptively improve the first power of the GFTR, so that the signal intensity when the GFTR reaches the network device is multiple times of px, which is equivalent to that a plurality of terminal devices simultaneously transmit the GFTR. When the network device obtains the number N of GFTRs, the magnitude of GFTA is estimated. The network device estimates the size of the GFTA considering the fact that N may be smaller than the actual number of GFTR transmissions, and the size of the GFTA satisfies the requirement that the success rate of these unlicensed data transmissions reaches URLLC. The network device may determine the resource pool size according to the number N and a preset correction factor.

In this implementation, a plurality of terminal devices send GFTRs on a common first preset resource, so that a network device detects the total power of all GFTRs, and controls the sending power of the GFTRs at the same time, so that the target signal strengths of the GFTRs sent by different terminal devices are the same, and the network device can determine the number of the GFTRs according to the total power on the first preset resource and the target signal strength of a single GFTR.

S303, the network equipment sends GFTA information to each terminal equipment.

For example, S303 in this embodiment is the same as S203 in the embodiment shown in fig. 2, and details are not repeated in this application.

In this embodiment, the terminal device performs GFTR transmission on the first preset resource of any timeslot, and the network device periodically receives GFTR on the first preset resources of all timeslots, thereby ensuring reliability of GFTR transmission between the network device and the terminal device. Therefore, the network equipment can generate GFTA information according to the received GFTR, the size of the resource pool indicated in the GFTA information is configured according to the data volume to be sent, and the resource pool configuration is more reasonable.

Exemplarily, on the basis of the embodiment shown in fig. 3, an embodiment of the present application further provides a resource pool configuration method. In this embodiment, in order to ensure that the terminal device receives the GFTA information sent by the network device, the sending and receiving timings of the GFTA information are described in detail. Fig. 6 is a signaling flow diagram of a resource pool configuration method according to a third embodiment of the present application. As shown in fig. 6, a resource pool configuration method provided in the embodiment of the present application includes:

s601, the terminal device sends a GFTR to the network device on a first preset resource in a first time slot.

S602, the network device receives a GFTR sent by at least one terminal device on a first preset resource in a first timeslot, and generates GFTA information according to the GFTR.

For example, S601 and S602 in this embodiment are the same as S301 and S302 in the embodiment shown in fig. 3, and are not described again in this application.

S603, the network device sends GFTA information to each terminal device on a second preset resource in a second timeslot.

Wherein the second time slot is not earlier than the first time slot.

Correspondingly, the terminal equipment receives the GFTA information on a second preset resource in a second time slot.

Illustratively, after the network device generates the GFTA information according to the received GFTR, the network device sends the GFTA information to each terminal device on the second preset resource. Correspondingly, the terminal equipment receives the GFTA information on the second preset resource. The second preset resource is a part of resources on the downlink time-frequency resource corresponding to the second time slot, and the second time slot is a time slot which is not earlier than the first time slot. For example, the position of the part of resources on the uplink time-frequency resource corresponding to the second time slot may be a fixed position, and may also be dynamically configured by the network device. The network device may notify the terminal device of the position of the second preset resource in the uplink time-frequency resource corresponding to the second time slot through the system broadcast information and the high-level signaling. After the terminal device sends the GFTR to the network device at the first time slot, the terminal device receives the GFTA information at the second preset resource in the downlink time-frequency resource corresponding to the second time slot. If the terminal device does not transmit the GFTR, the terminal device does not receive the GFTA information. For example, since the first time slot may be any time slot, each time slot has a first predetermined resource, each first time slot has a corresponding second time slot, and the second time slot has a second predetermined resource, referring to fig. 4, each time slot has a second predetermined resource.

Further, the terminal device needs to switch from the transmission state to the reception state after transmitting the GFTR, and the terminal device needs to generate the GFTA information from the GFTR and switch from the reception state to the transmission state after receiving the GFTR. In order to improve the resource pool configuration efficiency and ensure the success rate of resource pool configuration, a time interval exists between the first preset resource and the second preset resource. The following describes the time interval between the first predetermined resource and the second predetermined resource in detail with reference to a specific embodiment.

A first possible time interval pattern is: the first time slot and the second time slot are separated by one time slot.

Illustratively, the time interval between the second time slot and the first time slot is related to the number of time slots contained in one subframe and the time required for the terminal device and the network device to process the received information. In the case that one subframe includes 8 slots as shown in fig. 4, since the time length of one subframe is 1 ms, the time length of each slot is 125 ms, and the second slot and the first slot are separated by one slot, so that regardless of whether the first preset resource is arranged in time domain or frequency domain (as in the horizontal arrangement in fig. 4), it can be guaranteed that the network device processes the received information and generates the GFTA information to be transmitted for at least one slot, i.e. 125 ms, after the terminal device transmits the GFTR, and it can be guaranteed that the terminal device switches from the transmitting state to the receiving state to receive the GFTA information after the terminal device has transmitted the GFTR. Referring to fig. 4, a terminal device transmits GFTR on a first preset resource in slot 1 and receives GFTA information on a second preset resource in slot 3. The network device receives the GFTR on the first preset resource in the time slot 1, generates GFTA information according to the GFTR before the second preset resource in the time slot 3, and sends the GFTA information on the second preset resource in the time slot 3. Illustratively, when the terminal device fails to transmit the GFTR on the first preset resource in slot 1, the terminal device transmits the GFTR on the first preset resource in slot 2, and correspondingly, the terminal device receives the GFTA information on the second preset resource in slot 4. Because a time slot is arranged between the receiving and sending of the terminal equipment and the network equipment, the reliability of the resource pool configuration is ensured; meanwhile, taking an example that one subframe includes 8 time slots, at this time, the terminal device only needs 4 OFDM symbols at most from the time when the terminal device generates the data to be transmitted to the time when the terminal device receives the resource pool configured by the network device, and the delay configured by the resource pool is small.

Optionally, the first time slot and the second time slot are separated by at least one time slot.

For example, if one subframe contains more slots, the number of slots of the time interval between the second slot and the first slot may be more. For example, if one subframe includes 16 slots, there may be a 2-slot interval between the second slot and the first slot, and there is still at least a 125-microsecond interval between the time when the terminal device sends the GFTR and the time when the terminal device switches from the sending state to the receiving state, which satisfies the time requirement between the terminal device or the network device processing the information from the received information to the time when the terminal device receives the GFTA information, and at this time, the time delay from the generation of data to the reception of the GFTA information by the terminal device does not exceed 0.25 milliseconds. If the terminal device and the network device process the received signal more quickly, the second time slot and the first time slot may be separated by only 1 time slot, which can better meet the delay requirement of URLLC.

A second possible time interval is: the first time slot and the second time slot are the same time slot or adjacent time slots, and an OFDM symbol is arranged between the first preset resource and the second preset resource.

Illustratively, when the information processing speed of the terminal device and the network device is faster, or considering that the GFTR provided by the embodiment of the present application includes less information, the time interval between the first preset resource and the second preset resource may be further shortened to at least one OFDM symbol.

Fig. 7 shows another subframe structure that may be applied in the embodiment of the present application, where the subframe in fig. 7 exemplarily includes 4 slots, and the subframe in fig. 7 adopts a frequency division scheme. As shown in fig. 7, the first time slot and the second time slot are adjacent time slots. The first preset resource may be arranged at a middle position of each slot and the second preset resource may be arranged at a start position of each slot. Meanwhile, the second preset resource of the second slot and the first preset resource of the first slot are separated by at least one OFDM symbol, and only one OFDM symbol is separated in fig. 7 as an example. At this time, the configuration speed of the resource pool can meet the requirement of the URLLC service. Since the time length of one OFDM symbol is long, the terminal device and the network device have to process the received information and transmit the information when the next resource arrives in time. Optionally, the first preset resource may be located on the left side of the time slot, the second preset resource is located in the middle of the time slot, and the first time slot and the second time slot are the same time slot.

In the embodiment of the application, the terminal device transmits the GFTR on the first preset resource in the first time slot, the network device receives the GFTR on the first preset resource in the first time slot and generates the GFTA information according to the received GFTR, and the network device transmits the GFTA information on the second preset resource in the second time slot, so that the reliability of GFTR and GFTA information transmission between the network device and the terminal device is ensured. Therefore, the network equipment can generate GFTA information according to the received GFTR, and the terminal equipment can adopt the resource pool indicated in the GFTA information to perform uplink data transmission. The size of the resource pool in this embodiment is configured according to the amount of data to be sent, and the resource pool configuration is more reasonable.

Further, on the basis of the embodiment shown in fig. 6, an embodiment of the present application further provides a resource pool configuration method. The embodiment relates to a process of sending uplink data on a resource pool indicated by GFTA information after terminal equipment receives the GFTA information sent by network equipment. Fig. 8 is a schematic signaling flow diagram of a resource pool configuration method according to a fourth embodiment of the present application. As shown in fig. 8, a resource pool configuration method provided in the embodiment of the present application includes:

s801, the terminal device sends GFTR to the network device on a first preset resource in a first time slot.

S802, the network equipment receives the GFTR sent by at least one terminal equipment on a first preset resource in a first time slot, and generates GFTA information according to the GFTR.

And S803, the network equipment sends the GFTA information to each terminal equipment on a second preset resource in a second time slot.

Wherein the second time slot is not earlier than the first time slot.

For example, S801 to S803 in this embodiment are the same as S601 to S603 in the embodiment shown in fig. 6, and are not repeated in this application.

And S804, the terminal equipment performs authorization-free transmission of the uplink data on the resource pool in the third time slot.

Wherein the third time slot is not earlier than the second time slot. Correspondingly, the network device receives the uplink data sent by each terminal device on the resource pool in the third time slot.

Illustratively, after receiving the GFTA information, the terminal device performs uplink data transmission on the resource pool indicated by the GFTA information. Correspondingly, the network equipment receives the uplink data sent by the terminal equipment in the resource pool Hasang. The resource pool is a part of resources on the uplink time-frequency resource corresponding to the third time slot, and the third time slot is not earlier than the second time slot. Illustratively, referring to fig. 4, since the size and location of the resource pool depend on the GFTR on the corresponding first preset resource, the size of the resource pool in each slot may be different.

The following describes the time interval between the second predetermined resource and the third predetermined resource in detail with reference to a specific embodiment.

A first possible time interval pattern is: the third time slot is separated from the second time slot by one time slot.

For example, referring to fig. 4, referring to the first spacing manner between the second timeslot and the first timeslot, the third timeslot and the second timeslot may be separated by one timeslot, so that regardless of whether the second preset resource is arranged in time domain or in frequency domain, it can be ensured that the terminal device processes the received information and switches from the receiving state to the transmitting state to transmit in the resource pool of the third timeslot at least one timeslot, i.e. 125 microseconds after receiving the GFTA information. For example, the terminal device generates data in timeslot 1 shown in fig. 4 and transmits GFTR in the first preset resource of timeslot 1, the network device transmits GFTA information in the second preset resource of timeslot 3, and then the terminal device performs the unlicensed data transmission in the resource pool of timeslot 5. If the terminal device misses the opportunity of sending the GFTR in the time slot 1, the GFTR is sent in the first preset resource of the time slot 2, the network device sends the GFTA information in the second preset resource of the time slot 4, and the network device conducts the license-free data transmission in the resource pool of the time slot 6. At this time, the time elapsed from the generation of data by the terminal device to the transmission of the data over the resource pool is at most 6 OFDM symbols, 0.75 msec. The time interval among the first preset resource, the second preset resource and the resource pool is set, so that the time delay of resource pool configuration is reduced.

Optionally, the second time slot and the third time slot are separated by at least one time slot.

For example, if one subframe includes more slots, the number of slots of the time interval between the second slot and the third slot may be more. For example, one subframe includes 16 timeslots, then 2 timeslots may be separated between the third timeslot and the second timeslot, and after receiving the GFTA information sent by the network device, the terminal device still has at least 125 microseconds to determine the resource pool indicated by the GFTA information, and sends uplink data on the resource pool, so as to meet the time requirement from the time when the terminal device or the network device receives the information pair information in the URLLC service to the time when the uplink data is sent, and at this time, the delay from the time when the terminal device generates data to the time when the terminal device sends the uplink data according to the GFTA information does not exceed 0.5 milliseconds. If the terminal device and the network device process the received signal more quickly, the second time slot and the first time slot may be separated by only 1 time slot, which can better meet the delay requirement of URLLC.

A second possible time interval is: the second time slot and the third time slot are the same time slot or adjacent time slots, and an OFDM symbol is arranged between the second preset resource and the resource pool.

For example, referring to fig. 4, referring to the second interval manner between the second time slot and the first time slot, if the terminal device and the network device do not need much time for processing the received data, for example, the time of 1 to 2 OFDM symbols is enough, one time slot may not be needed between the third time slot and the second time slot, and only the number of symbols needed for the interval between the resource pool of the third time slot and the second preset resource of the second time slot is needed, so that the time delay from the generation of the data by the terminal device to the transmission of the data may be shortened to be within 0.5 ms.

As shown in fig. 7, if one subframe includes 4 slots, a first preset resource may be arranged at the middle position of each slot, a second preset resource may be arranged at the start position of each slot, a resource pool is arranged at the right side of each slot, the second slot is adjacent to the first slot, and the third slot is the same slot as the second slot, while at least one OFDM symbol is spaced between the second preset resource of the second slot and the first preset resource of the first slot and between the resource pool and the second preset resource in the second slot (i.e., the third slot). At this time, the time length of one OFDM symbol is long, and the terminal device and the network device have sufficient performance to process the received information and transmit the information when the next resource arrives in time. Optionally, the first preset resource may also be set on the left side of the time slot, the second preset resource is set in the middle of the time slot, the resource pool is set on the left side of the time slot, the first time slot and the second time slot are the same time slot, the third time slot is adjacent to the second time slot, and at least one OFDM symbol is also spaced between the second preset resource and the first preset resource in the second time slot (i.e., the first time slot) and between the resource pool of the third time slot and the second preset resource in the second time slot. At this time, the configuration speed of the resource pool can meet the requirement of the URLLC service.

In the embodiment, the terminal equipment transmits the GFTR on the first preset resource in the first time slot, the network equipment transmits the GFTA information generated according to the GFTR to the terminal equipment on the second preset resource in the second time slot, and data transmission is performed on the resource pool indicated by the GFTA information, so that the transmission of the GFTR, the GFTA information and the uplink data between the network equipment and the terminal equipment is ensured. Therefore, the network device can generate GFTA information according to the received GFTR and perform data transmission on the resource pool indicated in the GFTA information.

For example, the resource pool configuration method in the foregoing embodiments may also be applied to a subframe that employs a time division scheme as shown in fig. 5.

The subframe shown in fig. 5 includes 8 time slots, and exemplarily time-frequency resources corresponding to a plurality of OFDM symbols on the left side of each time slot may be specified for downlink transmission, where the OFDM symbols are referred to as downlink OFDM symbols; and the time frequency resources corresponding to the right several symbols are used for uplink transmission, and these OFDM symbols are called uplink OFDM symbols. The allocation of the number of uplink OFDM symbols and downlink OFDM symbols in each slot may be different. For example, the first preset resource may be a part of time-frequency resource corresponding to the first OFDM symbol on the right side in the uplink OFDM symbol of each time slot, the second preset resource may be a part of time-frequency resource corresponding to the first OFDM symbol on the left side in the downlink OFDM symbol of each time slot, and the resource pool may be a part of time-frequency resource corresponding to the uplink OFDM symbol of each time slot. Other OFDM symbols in the subframe are used for downlink data transmission or uplink data transmission depending on the need for resources for uplink and downlink transmission (usually more resources are needed for downlink than for uplink).

For example, the interval between the first time slot and the second and third time slots may be the same as the time interval in the embodiment shown in fig. 4 or fig. 7. The following description is only exemplary of the interval between the time slots. When the terminal device generates URLLC data in slot 1, GFTR may be transmitted in the first preset resource of slot 1. The network equipment obtains the quantity N of the GFTRs from the first preset resource of the time slot 1, configures a resource pool for the terminal equipment according to the N, generates GFTA information, and then sends the GFTA information on the second preset resource of the time slot 3. And the terminal equipment receives the GFTA information on the second preset resource of the time slot 3, and selects a transmission unit on the resource pool of the time slot 5 for uplink data transmission according to the GFTA information. For example, the first slot and the second slot may also be adjacent slots or the same slot, and the first preset resource and the second preset resource are separated by at least one OFDM symbol. Illustratively, when the terminal device fails to transmit the GFTR on the first preset resource in the timeslot 1, the terminal device transmits the GFTR on the first preset resource in the timeslot 2, and correspondingly, the terminal device receives the GFTA information on the second preset resource in the timeslot 4 and performs uplink data transmission on the resource pool in the timeslot 6. Because a time slot is arranged between the receiving and sending of the terminal equipment and the network equipment, the reliability of the resource pool configuration is ensured; meanwhile, taking an example that one subframe includes 8 time slots, at this time, the terminal device performs uplink data transmission on a resource pool configured by the network device from the time when the data to be transmitted is generated, and only 6 OFDM symbols are needed at most, thereby meeting the delay requirement of the URLLC service.

For example, the first time slot, the second time slot, and the third time slot in any of the above embodiments may be distributed in different subframes. The first preset resource may be a part of time frequency resources occupied by an Uplink Control Channel (PUCCH) in Uplink time frequency resources corresponding to the first time slot. The second preset resource may be a part of time frequency resources occupied by a Downlink Control Channel (PDCCH) in Downlink time frequency resources corresponding to the second time slot.
