Description

Technical Field

[0001] The present invention relates to the field of wireless communication technologies, and particularly to a resource allocation method, device, and system. Background Art

[0002] Currently, in the application process of Narrow Band Internet of Things (NB-IoT) / LTE enhanced Machine-Type Communication (eMTC), when there is uplink data arriving at a Non-terrestrial network (NTN) User Equipment (UE), the UE wakes up and performs Global Navigation Satellite System (GNSS) measurement to complete downlink synchronization. Among them, NB-IoT obtains Narrowband Physical Random Access Channel (NPRACH) resources by reading System Information Block 2 (SIB2), and then reads SIBx carrying ephemeris information, and sends a random access preamble signal on the corresponding NPRACH resources according to the coverage level.

[0003] However, since the NTN IoT UE needs to read the SIB information carrying the ephemeris before sending the preamble signal and send the preamble signal on a subframe that meets the NPRACH transmission period and subframe offset conditions, it often causes a large number of IoT UEs to access in the same time period, resulting in NPRACH congestion, leading to random access process failure or too long access time.

[0004] In summary, the currently provided method for resource allocation in the random access process has too long access time and a high failure rate. Summary of the Invention

[0005] Embodiments of the present invention provide a resource allocation method, device, and system, so as to provide an efficient, flexible, and high-success-rate resource allocation method.

[0102] Currently, during the application of NB-IoT / eMTC, when uplink data arrives at the NTN IoT terminal UE, the UE wakes up and performs GNSS measurement to complete downlink synchronization. Among them, NB-IoT obtains NPRACH resources by reading the system information of SIB2, and then reads SIBx carrying ephemeris information, and sends a Preamble signal on the corresponding NPRACH resources according to the coverage level.

[0103] Exemplarily, currently the starting time of NPRACH transmission needs to satisfy after the starting point of the radio frame of ms, the terminal reads SIBx carrying ephemeris information to obtain the configuration information of NPRACH resources, and the terminal determines the NPRACH resources for sending the Preamble signal. Then, calculate the timing advance TA for NPRACH transmission, and at after the starting point of the radio frame of ms, use the said NPRACH resources to send the Preamble signal according to the specified number of repetitions.

[0104] However, since the NTN IoT UE needs to read SIBx information before sending the Preamble signal and send the preamble signal on the subframe that meets the NPRACH transmission period and subframe offset conditions, therefore, it often causes a large number of IoT UEs to access in the same time period as shown in Figure 1 , resulting in NPRACH congestion, leading to the failure of the random access process or too long access time.

[0105] In summary, for the method of resource allocation during the current random access process provided, the random access time is too long and the failure rate is relatively high.

[0106] To solve the above problems, an embodiment of the present application provides a resource allocation method. The technical solution of the embodiment of the present application can be applied to various communication systems. For example, it can be applied to the communication system provided by the embodiment of the present application, or it can be applied to existing global system for mobile communications (GSM) systems, code division multiple access (CDMA) systems, wideband code division multiple access (WCDMA) systems, general packet radio service (GPRS), long term evolution (LTE) systems, LTE frequency division duplex (FDD) systems, LTE time division duplex (TDD), universal mobile telecommunication system (UMTS), worldwide interoperability for microwave access (WIMAX) communication systems, fifth generation (5G) systems or new radio (NR), or it can be applied to future communication systems or other similar communication systems, etc.

[0107] Taking the 5G system (which can also be called the new radio system) as an example, specifically, new communication scenarios are defined in the 5G system: ultra-reliable and low-latency communication (URLLC), enhanced mobile broadband (eMBB), and massive machine type communication (mMTC). These communication scenarios have more stringent requirements for communication quality and power consumption savings. Therefore, it is particularly important to achieve flexible, efficient, and low-power communication transmission.

[0108] Taking the 5G system (which can also be called the New Radio system) as an example, specifically, new communication scenarios are defined in the 5G system: Ultra-Reliable and Low-Latency Communication (URLLC), Enhanced Mobile Broadband (eMBB), and Massive Machine Type Communication (mMTC). These communication scenarios have more stringent requirements for the timeliness and success rate of communication information transmission. Especially in the scenario of massive machine type communication, in the face of a large number of UEs accessing in the same time period, there are more stringent requirements on how to avoid the NPRACH congestion phenomenon and improve the success rate of the random access process. Therefore, it is more important to provide an efficient, flexible, and high-success-rate resource allocation method.

[0109] To better ensure the success rate of random access and effectively shorten the random access time, the embodiment of the present application proposes a resource allocation method for the random access process. Since multiple available NPRACH opportunities are added in this method, the terminal can randomly select one from multiple available NPRACH opportunities to send the Preamble signal, so that at least one terminal performing random access can be dispersed to different NPRACH transmission opportunities, reducing the conflict probability, and thus effectively avoiding the problem that the random access fails due to the NPRACH transmission conflict caused by the terminals concentrating on the same NPRACH opportunity to initiate random access.

[0110] To facilitate the understanding of the embodiment of the present application, first, Figure 2 the communication system shown in

[0111] is taken as an example to detail the communication system applicable to the embodiment of the present application. Figure 2 As shown in

[0112] the communication system includes at least one terminal device 200 and a network device 210.

[0113] The network device 210 is a device that provides wireless communication functions for the terminal device 200 in a communication system and can connect the terminal device 200 to a wireless network. The network device 210 can also be referred to as a base station (BS). Currently, some examples of network devices 100 are: the next-generation base station (g nodeB, gNB) in 5G, evolved node B (eNB), radio network controller (RNC), node B (NB), base station controller (BSC), base transceiver station (BTS), home base station (e.g., home evolved nodeB, or home node B, HNB), baseband unit (BBU), transmitting and receiving point (TRP), transmitting point (TP), mobile switching center, etc.

[0114] It should be noted that when implementing the resource allocation method described in the embodiments of the present application, the execution entity can be the above device, or a chip in the above device, or a functional module in the above device. The embodiments of the present application do not make specific limitations on this. It should be understood that the network architecture applied to the present application is only an example described from the perspective of a service-oriented architecture. The network architecture applicable to the embodiments of the present application is not limited to this, and any network architecture that can implement the functions of the above-mentioned network elements is applicable to the embodiments of the present application.

[0115] The network architecture and service scenarios described in the embodiments of the present application are for more clearly illustrating the technical solutions of the embodiments of the present application, and do not constitute a limitation on the technical solutions provided by the embodiments of the present application. Those of ordinary skill in the art know that with the evolution of the network architecture and the emergence of new service scenarios, the technical solutions provided by the embodiments of the present application are equally applicable to similar technical problems.

[0116] Among them, the above Figure 2 is only a simplified schematic diagram for easy understanding. Other devices (network elements) may also be included in this network architecture, Figure 2 which are not drawn in the figure. For example, in an optional manner of the embodiments of the present application, the communication system may further include core network devices, etc.

[0117] The following further explains some terms involved in the embodiments of the present application to facilitate understanding.

[0118] (1)Ephemeris refers to the precise position or trajectory table of celestial body operation that changes over time in measurements such as the Global Positioning System (GPS) and GNSS. It is a function of time.

[0119] Among them, satellite ephemeris, also known as Two-Line Orbital Element (TLE), is an expression used to describe the position and velocity of a space vehicle.

[0120] (2)The Internet of Things (IoT), that is, "the Internet where all things are connected", is a network that extends and expands on the basis of the Internet. It is a huge network formed by combining various information sensing devices with the network, realizing the interconnection and interoperability of people, machines, and things at any time and any place.

[0121] (3)System Information Block (SIB) mainly refers to the system information broadcast by the base station and is divided into various types so that it can be sent at different frequencies.

[0122] For example, SIB1 information mainly includes relevant parameters for the UE to evaluate whether it can access the current cell and system scheduling. SIB2 information mainly includes common radio resource configuration information, timers and constants, cell access prohibition information, etc. SIB3 information mainly includes information related to cell reselection and information related to intra-frequency cell reselection. SIB4 information mainly includes information related to intra-frequency neighboring cells. SIB5 information mainly includes information related to inter-frequency neighboring cells.

[0123] Among them, the SIBx information in the embodiments of the present application is mainly used to carry ephemeris information.

[0124] In an optional manner of the embodiments of the present application, the SIB carrying the ephemeris can be an expansion or content update of the content included in the existing SIB information. For example, the SIBx carrying the ephemeris information can be carried in SIB1; it can also be a newly developed SIB.

[0125] In addition, when the embodiments of the present application are applied to random access in the satellite Internet of Things, the system information of the ephemeris is carried in the SIB carrying the ephemeris. When the SIB carrying the ephemeris sends the ephemeris information, the SIB carrying the ephemeris also carries the timestamp information indicating the time when the ephemeris information is sent.

[0126] (4) Narrow Band Internet of Things (NB-IoT), an important branch of the Internet of Everything, is also called Low Power Wide Area Network (LPWAN). Among them, NB-IoT is built on the cellular network, only consuming about 180 kHz of bandwidth, and can be directly deployed on the GSM network, UMTS network or LTE network to reduce deployment costs and achieve smooth upgrades. It supports cellular data connections for low-power devices in the wide area network and enables efficient connections for devices with long standby times and high requirements for network connections.

[0127] (5) Reference Signal Receiving Power (RSRP) is one of the key parameters representing the wireless signal strength and a physical layer measurement requirement in the LTE network. It is the average value of the signal power received on all resource elements (REs) carrying reference signals within a certain symbol.

[0128] Among them, the term "at least one" in the embodiments of this application refers to one or more, and "multiple" refers to two or more. "And / or" describes the association relationship of associated objects, indicating that three relationships can exist. For example, A and / or B can represent: A exists alone, A and B exist simultaneously, and B exists alone. Among them, A and B can be singular or plural. The character " / " generally represents an "or" relationship between the associated objects before and after. The following "at least one (item)" or its similar expressions refer to any combination of these items, including any combination of single (item) or plural items. For example, at least one (item) of a, b, or c can represent: a, b, c, a - b, a - c, b - c, or a - b - c, where a, b, c can be single or multiple.

[0129] Unless otherwise stated, the ordinal numbers such as "first" and "second" mentioned in the embodiments of this application are used to distinguish multiple objects and are not used to limit the order, timing, priority, or importance of multiple objects.

[0130] In addition, the terms "include" and "have" in the embodiments of this application and the claims and the drawings are not exclusive. For example, a process, method, system, product, or device that includes a series of steps or modules is not limited to the listed steps or modules, and may also include steps or modules that are not listed.

[0131] Further, as Figure 3 shown, the embodiments of the present invention provide a resource allocation method, and the method includes:

[0132] S300. The terminal device determines N NPRACH transmission resources corresponding to the transmission period of the SIB carrying the ephemeris according to the transmission period of the SIB carrying the ephemeris and the configuration information of the NPRACH transmission resources notified in SIB2, where N is a natural number greater than 0.

[0165] Case 1: The radio frame where the terminal device is located is an integer multiple of the configuration period of the NPRACH transmission resource.

[0166] Specifically, the terminal device determines N NPRACH transmission resources in the transmission period of the SIB carrying the ephemeris according to the transmission period of the SIB carrying the ephemeris, the first processing time, and the configuration period of the NPRACH transmission resource; where the first processing time is the time for the terminal device to read and / or decode and analyze the SIB carrying the ephemeris.

[0168] ; Formula 1

[0169] Wherein, represents the number N of NPRACH transmission resources, represents the transmission period of the SIB carrying the ephemeris, represents the first processing time, represents the configuration period of the NPRACH transmission resources.

[0175] Further, in the embodiment of the present application, for the above-mentioned situation 2, the following formula 2 is provided to determine N NPRACH transmission resources corresponding to the SIB period of the carried ephemeris:

[0176] Formula 2

[0177] Wherein represents the number N of NPRACH transmission resources, represents the transmission period of the SIB carrying the ephemeris, represents the first processing time, represents the radio frame serial number, Indicates the duration corresponding to the radio frame Indicates the configuration period of the NPRACH transmission resource.

[0179] Further, in the embodiments of this application, there are multiple ways for the terminal device to randomly select one NPRACH transmission resource from the N NPRACH transmission resources, and specifically, it is not limited to the following several:

[0180] Selection method 1: Directly randomly select one NPRACH transmission resource from the N NPRACH transmission resources.

[0184] It should be noted that Formula 3 described in this application is only used for illustration and does not constitute a limitation on the embodiments of this application. Any solution for selecting transmission resources by modifying Formula 3 described in this application belongs to the protection scope of the embodiments of this application.

[0185] Selection method 2: The terminal device randomly selects one NPRACH transmission resource from the M NPRACH transmission resources; where M is a natural number greater than 0 and M is less than or equal to N.

[0186] Exemplarily, assume that the terminal device determines that there are a total of 5 NPRACH transmission resources corresponding to the transmission period of the SIB carrying the ephemeris, namely NPRACH transmission resources 1 to 5. Then, the terminal device randomly selects from the transmission resources 2 to 4 among the NPRACH transmission resources 1 to 5.

[0193] It should be noted that the formula 4 in this application is only used for illustration and does not constitute a limitation on the embodiments of this application. Any solution for selecting transmission resources based on the deformation of the formula 4 in this application falls within the protection scope of the embodiments of this application.

[0194] Furthermore, when the terminal device in an embodiment of this application performs random access to the network device through the selected transmission resources, certain conditions need to be met, that is, random access is performed to the network device at the transmission resource start time after the start time of the radio frame when the transmission time point of the selected transmission resource is zero.

[0195] Exemplarily, the start time of the NPRACH transmission resources is as follows:

[0196] {8, 16, 32, 64, 128, 256, 512, 1024} ms

[0197] where the time start point of the transmission resources is after the start time of the radio frame that satisfies ms.

[0199] As Figure 4As shown, it is assumed that there are 4 NPRACH resources within the transmission period of the SIBx, and all of them can be used.

[0200] Among them, at the same time, terminal devices 1 to 3 perform random access. Using the resource allocation method described in the embodiments of the present application, it is assumed that when terminal device 1 performs random access, NPRACH resource 1 is selected; when terminal device 2 performs random access, NPRACH resource 4 is selected; and when terminal device 3 performs random access, NPRACH resource 2 is selected.

[0201] As Figure 5 shown, it is assumed that there are 4 NPRACH resources within the transmission period of the SIBx, and the network device indicates that only NPRACH resources 1 to 3 can be used by the terminal device.

[0205] S600. The terminal device determines a second NPRACH transmission resource according to a preset delay time and a first NPRACH transmission resource.
