Description

Technical Field

[0001] This application relates to the field of communication technologies, and in particular, to a resource allocation method and apparatus. Background Art

[0002] The next-generation mobile network new radio (NR) system will provide an unprecedented number of connected devices and ubiquitous network coverage. It is predicted that in the future, more than 50 billion connected devices will access the network, that is, more than 6 connected devices per person (including communication between people, between people and machines, and between machines). However, at the same time, according to the current design scheme, the improvement of wireless communication performance will inevitably come at the cost of increased energy consumption. That is to say, the base stations in the network will process massive amounts of device data.

[0003] A large number of access devices will lead to resource fragmentation and reduce resource utilization. Summary of the Invention

[0004] This application provides a resource allocation method and apparatus to solve the problem of how to improve resource utilization.

[0005] In a first aspect, this application provides a resource allocation method, which can be executed by a network device or by components (such as chips or circuits) configured in the network device. The method includes: obtaining channel state information of a resource grid; obtaining at least one resource demand information; a resource demand information indicating the time length and delay of the required resources; determining a candidate resource pool from the resource grid; wherein the candidate resource pool is a set of resources within a sliding window of the resource grid; the window width of the sliding window is determined according to the maximum time length indicated in the at least one resource demand information; the position of the sliding window in the resource grid is determined according to the channel state information and the delay indicated in the at least one resource demand information; allocating resources for the at least one resource demand information in the candidate resource pool.

[0040] The embodiments of the present application will be described in detail below with reference to the accompanying drawings of the specification.

[0041] The technical solutions of the embodiments of the present application can be applied to various communication systems, such as a long term evolution (LTE) system, an LTE frequency division duplex (FDD) system, an LTE time division duplex (TDD), a 5th generation (5G) new radio (NR) system, or can be applied to future communication systems or other similar communication systems, etc.

[0042] To facilitate the understanding of the embodiments of the present application, first Figure 1 the communication system shown in is taken as an example to illustrate in detail the communication system applicable to the embodiments of the present application. Figure 1 shows a schematic diagram of a communication system of a communication method applicable to the embodiments of the present application. As Figure 1 shown, the communication system includes a network device and multiple terminal devices. In the figure, K terminal devices are taken as an example for illustration, and K is an integer greater than 1. The K terminal devices are heterogeneous services with different data requirements and latency requirements. After the services reach the network device, the network device transmits them to the K terminal devices.

[0043] It should be noted that latency is also referred to as delay or time delay in some documents, and in the present application, it is uniformly referred to as latency.

[0044] The embodiments of the present application can be applied to ultra-high reliability and low latency (URLLC) services, that is, transmitting data of URLLC services between a terminal device and a network device.

[0045] This application can be applied to scenarios where resource centralized scheduling is performed under an extensible subcarrier spacing and a flexible frame structure, to achieve refined shutdown of some modules in a network device (such as a power amplifier (PA)) for system energy saving. Specifically, this application can comprehensively consider various factors such as delay, reliability quality of service (QoS) constraints, the number of resource blocks to be allocated, and the size of the available time-frequency resource grid. When there is no data to be sent in the resource block, modules such as the PA are shut down to achieve the purpose of energy saving.

[0046] It should be understood that the network device may further include multiple components related to signal transmission and reception (such as a processor, a modulator, a multiplexer, a demodulator, or a demultiplexer, etc.).

[0047] In the embodiments of this application, the terminal device is a device with wireless transceiver functions or a chip that can be disposed in the device. Among them, the device with wireless transceiver functions may also be referred to as a user equipment (UE), an access terminal, a user unit, a user station, a mobile station, a remote station, a remote terminal, a mobile device, a user terminal, a user agent, or a user device. In practical applications, the terminal device in the embodiments of this application may be a mobile phone, a tablet computer (Pad), a computer with wireless transceiver functions, a virtual reality (VR) terminal, an augmented reality (AR) terminal, a wireless terminal in industrial control, a wireless terminal in self-driving, a wireless terminal in remote medical, a wireless terminal in a smart grid, a wireless terminal in transportation safety, a wireless terminal in a smart city, a wireless terminal in a smart home, and so on. The embodiments of this application do not limit the application scenarios. In this application, the aforementioned device with wireless transceiver functions and the chip that can be disposed in the device are collectively referred to as the terminal device.

[0048] In the embodiments of the present application, the network device may be a wireless access device under various systems. For example, it may be a next-generation base station (gNB) in the NR system, an evolved NodeB (eNB), a radio network controller (RNC), a Node B (NB), a base station controller (BSC), a base transceiver station (BTS), a home base station (e.g., home evolved NodeB, or home Node B, HNB), a baseband unit (BBU), an access point (AP) in a wireless fidelity (WIFI) system, a wireless relay node, a wireless backhaul node, a transmission and reception point (TRP or transmission point, TP), etc. It may also be a gNB or a transmission point (TRP or TP) in a 5G (NR) system, one or a group (including multiple antenna panels) of antenna panels of a base station in a 5G system, or a network node constituting a gNB or a transmission point, such as a baseband unit (BBU), or a DU in a central unit-distributed (CU-DU) architecture.

[0049] In addition, in the embodiments of the present application, the term "exemplary" is used to mean an example, illustration, or description. Any embodiment or design described as "exemplary" in this application should not be construed as being more preferred or having more advantages than other embodiments or designs. Rather, the use of the term "exemplary" is intended to present concepts in a concrete manner.

[0050] 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 will 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.

[0051] Figure 2 For example, when the interaction between the network device and the terminal device is taken as an example, the operations performed by the network device may also be performed by a chip or module inside the network device, and the operations performed by the terminal device may also be performed by a chip or module inside the terminal device. Refer to Figure 2 , the method includes:

[0052] Step 201: The network device obtains the channel state information of the resource grid.

[0053] The embodiments of the present application do not limit how the network device specifically obtains the channel state information of the resource grid, and will not elaborate here.

[0054] Among them, the resource grid can also be referred to as a two-dimensional (2-D) time-frequency resource grid or a time-frequency resource grid, and is hereinafter simply referred to as the resource grid. The network device can obtain the resource grid size from the upper protocol stack. The resource grid can include multiple minimum resource units. Each minimum resource unit can be called a basic unit, such as Figure 3 shown, which is a schematic diagram of a resource grid provided by the present application. Figure 3 The minimum resource unit included in the resource grid in has a length of one time unit in the time domain, for example, it can be equal to 0.125 ms; the width of the minimum resource unit in the frequency domain is 1 subcarrier spacing, and one subcarrier spacing is at least 15 KHz.

[0055] It should be noted that the embodiments of the present application do not limit how many time units the resource grid specifically includes and how many subcarriers it occupies.

[0056] In the embodiments of the present application, when allocating resources, it can be allocated in units of resource blocks (RBs). Generally, one RB includes at least 1 minimum resource unit. Among them, the length of one RB in the time domain can be called a Transmission Time Interval (TTI). For example, as Figure 4 shown, taking one RB including 4 minimum resource units as an example, there may be multiple types of RBs. The sizes of different types of RBs are equal, but the shapes are different. At the same time, the number of time domain units included in the Transmission Time Interval (TTI) and the number of frequency domain basic units included in the subcarrier spacing are different, and the two are inversely proportional. Figure 4Three types of RBs are exemplified, namely RB type 1, RB type 2, and RB type 3. RB type 1 includes 1 time unit in the time domain and occupies 4 subcarriers in the frequency domain; RB type 2 includes 2 time units in the time domain and occupies 2 subcarriers in the frequency domain; RB type 3 includes 4 time units in the time domain and occupies 1 subcarrier in the frequency domain. Taking the time length of a minimum resource unit as 0.125 ms and occupying 1 subcarrier of 15 kHz in the frequency domain as an example, the subcarrier spacings of RB type 1, RB type 2, and RB type 3 are 60 kHz, 30 kHz, and 15 kHz respectively; the transmission time intervals (TTIs) of RB type 1, RB type 2, and RB type 3 are composed of 7 orthogonal frequency division multiplexing (OFDM) symbols, and the corresponding durations are 0.125 ms, 0.25 ms, and 0.5 ms respectively.

[0057] Step 202: The network device obtains at least one resource requirement information.

[0058] How the network device specifically obtains at least one resource requirement information is not limited in this application. For example, the network device can obtain at least one resource requirement information from the upper protocol stack. Or the network device can obtain the resource requirement information from at least one terminal device, and each terminal device can send one or more resource requirement information to the network device.

[0059] In the embodiments of this application, a resource requirement information indicates the time length and delay of the required resources. For example, a resource indicated by a resource requirement information is the resources included in an RB type. For example, if the resource indicated by the resource requirement information is the resources included in RB type 1, then the resources indicated by this resource requirement information occupy 1 time unit in the time domain and 4 subcarriers in the frequency domain.

[0060] It should be noted that when the embodiments of this application are applied to URLLC, the size of the data packet carried by the required resources indicated by the resource requirement information is greater than or equal to 20 bytes and less than or equal to 200 bytes. The delay of the required resources indicated by the resource requirement information is less than or equal to 1 millisecond.

[0061] Step 203: The network device determines a candidate resource pool from the resource grid.

[0062] Among them, the candidate resource pool is a set of resources located within the sliding window of the resource grid; the sliding window is determined according to the at least one resource requirement information and the channel state information, which will be described in detail later.

[0063] Step 204: The network device allocates resources for the at least one resource requirement information in the candidate resource pool.

[0064] By the above method, allocating resources for at least one resource requirement information in the candidate resource pool within the sliding window can ensure that all allocated resources are concentrated together, realizing the centralized allocation of resource blocks in the resource grid, making full use of the resources in the resource grid, and improving resource utilization. At the same time, outside the sliding window, the network device can refrain from allocating resources externally, so these resources do not need to transmit data, and the network device can thus turn off modules such as PA to achieve energy saving, thereby enhancing energy efficiency.

[0065] Combined with the previous description, as Figure 5 shown, it is a schematic diagram of resource allocation provided by an embodiment of the present application.

[0066] Step 501: The network device obtains at least one resource requirement information.

[0067] For example, the network device determines that 7 resources need to be allocated according to the at least one resource requirement information, including 2 resources of RB type 1, 2 resources of RB type 2, and 3 resources of RB type 3.

[0068] Step 502: In the resource grid, the network device determines the sliding range of the sliding window.

[0069] Specifically, the delay of the resources in the sliding range of the sliding window is between Ds and D L .

[0070] D S is less than or equal to the minimum delay indicated in the at least one resource requirement information. D L is greater than or equal to the maximum delay indicated in the at least one resource requirement information.

[0071] Furthermore, if resources of multiple RB types need to be allocated, the maximum delay of each RB type of resource can be determined; Ds and D L can be determined according to the maximum delay of each RB type of resource. For example, the maximum delay among the 2 resources of RB type 1 is D1 max ; the maximum delay among the 2 resources of RB type 2 is D2 max ; the maximum delay among the 3 resources of RB type 3 is D3 max ; then D S = min{D1 max , D2 max , D3 max}, D L = max{D1 max , D2 max, D3 max}, where min represents the minimum operation and max represents the maximum operation.

[0072] Step 503: The network device determines the window width of the sliding window.

[0073] In the embodiments of the present application, the window width of the sliding window is determined according to the maximum time length indicated in the at least one resource requirement information. Specifically, the window width of the sliding window is greater than or equal to the maximum time length indicated in the at least one resource requirement information.

[0074] In the embodiments of the present application, taking the window width of the sliding window being equal to the maximum time length indicated in the at least one resource requirement information as an example for illustration, at this time the network device can determine the window width of the sliding window according to the following process:

[0075] Step 1: Whether the number of resources of RB type 3 to be allocated is greater than 0. If it is greater than 0, set the window width of the sliding window to the time length of the resources of RB type 3, that is, 4 time units; if the number of resources of RB type 3 to be allocated is equal to 0, go to Step 2;

[0076] Step 2: Whether the number of resources of RB type 2 to be allocated is greater than 0. If it is greater than 0, set the window width of the sliding window to the time length of the resources of RB type 2, that is, 2 time units; if the number of resources of RB type 2 to be allocated is equal to 0, go to Step 3;

[0077] Step 3: Whether the number of resources of RB type 1 to be allocated is greater than 0. If it is greater than 0, set the window width of the sliding window to the time length of the resources of RB type 1, that is, 1 time unit.

[0078] Step 504: The network device determines the position of the sliding window in the resource grid.

[0079] Specifically, in D S slide along the time axis (from back to front) before, find the candidate resource pool with the maximum average channel state information in the resource grid (that is, the average value of the channel state information of the resources included in the sliding window is the largest), and ensure that all resources within the sliding window are within the optional range of the resource with the minimum delay requirement.

[0080] Step 505: The network device allocates resources in the candidate resource pool.

[0081] Specifically, the network device can allocate resources to the at least one resource requirement information in ascending order of the time length of the resources indicated by the at least one resource requirement information.

[0082] When allocating resources, the network device can sequentially allocate the resources with the maximum average channel state information that are not occupied to the resources of RB type 1 to RB type 3 respectively.

[0083] For example, the network device can preferentially allocate 2 resources of RB type 1 in the candidate resource pool, then allocate 2 resources of RB type 2, and finally allocate 3 resources of RB type 2. The result after the final allocation can be referred to Figure 6 as shown. From Figure 6 it can be seen that the finally allocated resources are concentrated together, and the resources in the left half of the resource grid are in the unallocated state.

[0084] It should be noted that Figure 6 this is just an example, and there may be other allocation situations, such as Figure 7 , Figure 8 , Figure 9 and Figure 10 as shown, which gives the schematic diagrams of different resource allocations in the cases of different delays and different numbers of resources of RB type 1, RB type 2, and RB type 3.

[0085] Step 506: If all the resources in the candidate resource pool have been allocated and there are still resources to be allocated, then the sliding window can be re-determined according to steps 502 to 505, so as to perform resource allocation.

[0086] When the network device performs data transmission, when there is data in the resources within the resource grid, modules such as the PA of the network device can be in the on state; when there is no data in the resources within the resource grid, modules such as the PA of the network device can be in the off state.

[0087] The method provided in this application is superior to various algorithms in the prior art and can significantly reduce the energy consumption of the base station. As Figure 11 shows the comparison of the energy efficiency (EE) achieved by the method proposed in this application (Method 1), the spectrum efficiency maximum algorithm (Method 2), and the random algorithm (Method 3). The random algorithm is used as the baseline, that is, as long as there are available idle time-frequency resources before the delay requirement for the traffic flow, they will be allocated. Figure 11 shows the comparison of EE between different methods in the cases of the same delay and different delays. As the delay requirements for different RBs become more relaxed, when the delay requirement is relatively relaxed, the EE of the method proposed in this application is approximately 10.4% higher than that of the spectrum efficiency maximum algorithm at most, and approximately 12.9% higher than that of the random allocation method at most. The unit of EE is bps / J (bits per second per joule).

[0088] As shown in Table 1 below, as the size of the resource grid increases, the running time of the central processor unit (CPU) of the network device using the random algorithm is the smallest and is not affected by the change in the grid size. After using the method provided in this application, the CPU running time slightly increases as the grid size increases.

[0089] Table 1 CPU Running Time

[0090]

[0091] Figure 12 respectively shows the influence of the number of RBs and the size of the resource grid on the EE. In Figure 12(a), the delay requirements are fixed at (5, 5, 5)*0.125 ms (the delay requirements of different RBs are the same) and (3, 5, 7)*0.125 ms (the delay requirements of different RBs are different), and the relationship between the number of RBs and the energy efficiency is given under the conditions of using the method provided in this application (Method 1), the spectrum efficiency maximum algorithm (Method 2), and the exhaustive search method (Method 4). In Figure 12(a), the EE comparison between different methods is also given under the conditions of the same delay and different delays. As the number of RBs to be allocated increases, the system energy efficiency increases. The algorithm proposed in this application (Method 1) is close to the exhaustive search method (Method 4) and is superior to other methods, such as the spectrum efficiency maximum algorithm (Method 2), and the greater the EE gain as the number of RBs increases within the time period.

[0092] Figure 12(b) shows the size of the resource grid that can be selected by expanding along the time domain or the frequency domain with the number of RBs fixed. It can be seen that the method proposed in this application is still applicable under the change of the resource grid, and the results show that better EE gain can be obtained by using frequency diversity than by using time diversity, and it is also better than the effect of the spectrum efficiency maximum algorithm (Method 2).

[0093] The embodiment of this application also provides a communication device. Please refer to Figure 13 , which is a schematic structural diagram of another communication device provided by the embodiment of this application. The communication device 1300 includes: a transceiver module 1310 and a processing module 1320. This communication device can be used to implement the functions of the network device involved in any of the above method embodiments. For example, this communication device can be a network device or a chip or circuit included in the network device.

[0094] Exemplarily, when this communication device executes Figure 2When implementing the operations or steps corresponding to the network device in the method embodiments shown, the transceiver module 1310 is configured to obtain the channel state information of the resource grid and obtain at least one resource requirement information; one resource requirement information indicates the time length and delay of the required resources; the processing module 1320 is configured to determine a candidate resource pool from the resource grid; wherein, the candidate resource pool is a set of resources located within a sliding window of the resource grid; the window width of the sliding window is determined according to the maximum time length indicated in the at least one resource requirement information; the position of the sliding window in the resource grid is determined according to the channel state information and the delay indicated in the at least one resource requirement information; the processing module 1320 is further configured to allocate resources for the at least one resource requirement information in the candidate resource pool.

[0101] In a possible design, the delay of the required resources indicated by the one resource requirement information is less than or equal to 1 millisecond.
