Description

Technical Field

[0001] The present invention belongs to the field of wireless communication technology, and in particular relates to a wireless communication method, device and system that support the coexistence of services with different delay requirements. Background Art

[0002] Ultra-reliable and Low Latency Communications (URLLC) is an important application scenario in mobile communication technology, especially in 5G and future 6G networks. Its purpose is to provide extremely high reliability (close to 100%) and extremely low communication delay (usually in milliseconds or even sub-milliseconds) to meet applications with extremely high requirements for real-time and stability. It is widely used in fields such as autonomous driving, telemedicine, industrial automation, virtual reality and augmented reality that have high requirements for communication reliability and delay to achieve efficient, intelligent and safe operations. In ultra-reliable and low-latency communications, there are requirements for both reliability and delay. For reliability requirements, they are usually achieved through physical layer technologies such as diversity and channel coding; for delay requirements, resource allocation technology is also involved. The present invention focuses on resource allocation technology for meeting delay performance requirements.

[0003] Existing low-latency resource allocation technologies are mainly divided into two categories. The first category is grant-based resource allocation technology, such as earliest deadline first (EDF) scheduling. The second category is grant-free resource allocation technology, such as Semi-Persistent Scheduling (SPS), resource allocation based on non-orthogonal multiple access (NOMA), and rate splitting multiple access (RSMA).

[0004] The existing low-latency resource allocation method based on the semi-persistent scheduling principle mainly considers allocating a fixed number of resources to users at fixed times, so as to meet the user's latency requirements in a very simplified signaling manner. However, the following two aspects are less considered. First, the semi-persistent scheduling principle essentially adopts a reservation method, and there must be a lot of idle wireless resources. Second, in addition to services with high latency requirements, there are usually services with low latency requirements in the system. It is very meaningful to combine these two aspects and design a wireless communication method in which the semi-persistent scheduling principle is used to support services with high latency requirements, while using idle wireless resources to support services with low latency requirements. Summary of the invention

[0005] In view of the above problems, the present invention proposes a wireless communication method, device and system that support the coexistence of services with different delay requirements, which can improve the resource utilization efficiency of the semi-persistent scheduling principle.

[0006] In order to achieve the above technical objectives and the above technical effects, the present invention is implemented through the following technical solutions:

[0007] In a first aspect, the present invention provides a wireless communication method for supporting coexistence of services with different delay requirements, comprising:

[0008] Based on different latency requirements, users are classified into primary users and secondary users;

[0009] Allocate resources to the primary user;

[0010] Allocate resources to slave users;

[0011] Wireless communication is performed based on pre-established base station rules, primary user access rules, and secondary user access rules.

[0012] In combination with the first aspect, optionally, the primary user classification method includes:

[0013] For user n, according to the arrival characteristics of its service traffic and the requirement for delay, its resource requirement is determined as A n time slots per frame, all the n Users with a value ≥1 are classified as primary users.

[0014] In combination with the first aspect, optionally, the classification method for users includes:

[0015] All satisfying A n Users with a score <1 are classified as slave users.

[0016] In conjunction with the first aspect, optionally, allocating resources to the primary user specifically includes:

The number of remaining time slots in each frame of all channels is summed up, and all channels are sorted from largest to smallest according to the summed result.

[0019] Among all the unassigned primary users, sort them from largest to smallest according to their resource requirements, select the primary user ranked first, denoted as primary user i, and then select the first channel and allocate A to primary user i at a fixed position in each frame on the channel. itime slots, the set of time slots allocated to primary user i is denoted as X i .

[0023] In all satisfying k ≤A k Among the main users, select the first main user and record it as main user k j , as the master user associated with slave user j;

[0024] For slave user j, in the selected master user k j The resource allocation position is every m j A frame allocates 1 time slot to user j, and the set of resources allocated to user j is denoted as Y j , where the specific position of the allocated time slot is randomly determined, on the premise of ensuring that the resources allocated to different slave users do not conflict.

[0025] In combination with the first aspect, optionally, the rule of the base station is:

[0026] For primary user i, if the base station allocates resource X i If the base station detects that a signal is being sent, it will start to continuously send the "primary user i's resource is busy" signal; if the base station allocates resources X i If idle is detected, that is, no signal is sent, the sending of the "resource busy of primary user i" signal is stopped.

[0027] In combination with the first aspect, optionally, the access rule of the primary user is:

[0028] For primary user i, when a message arrives, resource X is allocated i After sending, it waits for receiving the ACK signal from the base station;

[0029] If primary user i does not receive ACK, the above process is repeated until an ACK signal is received or it is terminated by a higher-level protocol.

[0030] In combination with the first aspect, optionally, the access rule of the slave user is:

[0031] Assume that slave user j is associated with master user i. When a message arrives, it first monitors whether the base station sends a "master user i's resource busy" signal. If it receives the signal, it waits until it no longer receives the signal.

[0032] From user j in allocating resource X i Randomly select a time slot, then transmit the corresponding signal, and after sending, wait to receive the ACK signal from the base station;

[0033] If the ACK signal from the base station is not received, the slave user j stops transmitting and then monitors whether the base station sends a "master user i's resource is busy" signal. If the signal is heard, it waits until the signal is no longer received.

[0034] From user j in allocating resource Y j Retransmit the signal, and after sending, wait for receiving the ACK signal from the base station;

[0035] If user j does not receive an ACK signal from the base station, the above process is repeated until an ACK signal is received or the process is terminated by a higher-level protocol.

[0056] Example 1

[0057] An embodiment of the present invention provides a wireless communication method for supporting coexistence of services with different delay requirements, comprising the following steps:

[0058] (1) Based on different latency requirements, users are classified into primary users and secondary users;

[0059] (2) Allocate resources to the primary user;

[0060] (3) Allocating resources to slave users;

[0061] (4) Wireless communication is performed based on pre-established base station rules, primary user access rules, and secondary user access rules.

[0062] Based on the wireless communication method supporting the coexistence of services with different delay requirements (i.e., users with high delay requirements and users with low delay requirements) in the embodiment of the present invention, wireless resources that are idle by users with high delay requirements can be fully utilized, thereby improving the overall resource utilization efficiency of the system. Regardless of whether it is a user with high delay requirements or a user with low delay requirements, resource allocation is fixed and does not require dynamic application to the base station, thereby greatly reducing the complexity of signaling.

[0063] In a specific implementation of the embodiment of the present invention, the method for classifying primary users includes:

[0064] For user n, according to the arrival characteristics of its service traffic and the requirement for delay, its resource requirement is determined as A n time slots per frame, all the n Users with a value ≥1 are classified as primary users.

[0065] In a specific implementation of the embodiment of the present invention, the classification method for users includes:

[0066] All satisfying A n Users with a score <1 are classified as slave users.

[0067] In a specific implementation of the embodiment of the present invention, the allocating resources to the primary user specifically includes:

[0068] For all primary users, perform the following steps in order:

[0069] Assume that there are N channels in the system. On each channel, the time axis is divided into frames of equal length. Each frame contains the same number of S time slots. The number of remaining time slots in each frame of all channels is summed up, and all channels are sorted from largest to smallest according to the summed result.

[0070] Among all the unassigned primary users, sort them from largest to smallest according to their resource requirements, select the primary user ranked first, denoted as primary user i, and then select the first channel and allocate A to primary user i at a fixed position in each frame on the channel. i time slots, the set of time slots allocated to primary user i is denoted as X i .

[0071] In a specific implementation of the embodiment of the present invention, the allocating resources from the user specifically includes:

[0072] Assume that user j is a slave user whose resource requirement is A j , in all satisfied Among the natural numbers m, select the one with the smallest value, which is called the order of user j and is recorded as m j ;

[0073] For each primary user k, calculate the indicator Among them U k is the set of slave users that have been associated with master user k, and the index z for all master users k The values ​​of are sorted from large to small;

[0074] In all satisfying k ≤A k Among the main users, select the first main user and record it as main user k j , as the master user associated with slave user j;

[0075] For slave user j, in the selected master user k j The resource allocation position is every m j A frame allocates 1 time slot to user j, and the set of resources allocated to user j is denoted as Y j , where the specific position of the allocated time slot is randomly determined, on the premise of ensuring that the resources allocated to different slave users do not conflict.

[0076] In a specific implementation of the embodiment of the present invention, the rule of the base station is:

[0077] For primary user i, if the base station allocates resource X i If the base station detects that a signal is being sent, it will start to continuously send the "primary user i's resource is busy" signal; if the base station allocates resources X i If idle is detected, that is, no signal is sent, the sending of the "resource busy of primary user i" signal is stopped.

[0078] In a specific implementation of the embodiment of the present invention, the access rule of the primary user is:

[0079] For primary user i, when a message arrives, resource X is allocated i After sending, it waits for receiving the ACK signal from the base station;

[0080] If primary user i does not receive ACK, the above process is repeated until an ACK signal is received or it is terminated by a higher-level protocol.

[0081] In a specific implementation of the embodiment of the present invention, the access rule of the slave user is:

[0082] Assume that slave user j is associated with master user i. When a message arrives, it first monitors whether the base station sends a "master user i's resource busy" signal. If it receives the signal, it waits until it no longer receives the signal.

[0083] From user j in allocating resource X i Randomly select a time slot, then transmit the corresponding signal, and after sending, wait to receive the ACK signal from the base station;

[0084] If the ACK signal from the base station is not received, the slave user j stops transmitting and then monitors whether the base station sends a "master user i's resource is busy" signal. If the signal is heard, it waits until the signal is no longer received.

[0085] From user j in allocating resource Y j Retransmit the signal, and after sending, wait for receiving the ACK signal from the base station;

[0086] If user j does not receive an ACK signal from the base station, the above process is repeated until an ACK signal is received or the process is terminated by a higher-level protocol.

[0087] The wireless communication method supporting coexistence of services with different delay requirements in an embodiment of the present invention is described in detail below in conjunction with a specific implementation manner.

[0088] The present invention provides a technical solution, considering the following Figure 5 The scenario shown in , which includes the following steps:

[0089] Step 1: Categorize users, such as Figure 1 as shown in .

[0090] In this step, for each user n, according to the arrival characteristics of its service traffic and the requirement for delay, its resource requirement can be determined as A according to some existing method. n time slots per frame. n Users with a high latency requirement of ≥1 are called primary users. n Users with low latency requirements of <1 are called slave users.

[0091] Step 2: Allocate resources to the primary user, such as Figure 1 as shown in .

[0092] In this step, corresponding resources are allocated to each primary user i. Assume that there are N channels in the system. On each channel, the time axis is divided into frames of equal length, and each frame contains the same number of S time slots. The number of remaining time slots in each frame of all channels is summed up, and all channels are sorted from large to small according to the summation result. Among all the unallocated primary users, they are sorted from large to small according to their resource requirements, and the first primary user is selected, recorded as primary user i, and then the first channel is selected, and A is allocated to primary user i at a fixed position in each frame on the channel. i time slots, the set of time slots allocated to primary user i is denoted as X i .

[0093] Step 3: Allocate resources to the slave users, such as Figure 1 as shown in .

[0094] In this step, it is assumed that user j is a slave user whose resource requirement is A. j In all satisfied Among the natural numbers m, select the one with the smallest value, which is called the order of user j and is recorded as m j .

[0095] In this step, for each primary user k, the index is calculated Among them U k is the set of slave users that have been associated with master user k. k The values ​​are sorted from large to small (i.e. according to z k The primary users are sorted by the values ​​of k ≤A k Among the main users, select the first main user and record it as main user k j , as the master user associated with slave user j.

[0096] In this step, for user j, in the selected primary user k j The resource allocation position is every m j A frame is allocated 1 time slot from user j. A specific example is Figure 6 Given in. Let the set of resources allocated from user j be Y j .

[0097] In this step, there is a relationship Y j ∈X i Established.

[0098] In this step, it is sufficient to ensure that the resources allocated to different slave users do not conflict with each other, and the specific positions of the allocated time slots can be determined randomly.

[0099] Step 4: Generate base station rules, such as Figure 2 as shown in .

[0100] In this step, for each primary user i, if the base station allocates resource X i When a signal is detected, it starts to continuously send the "primary user i's resource is busy" signal.

[0101] In this step, for each primary user i, if the base station allocates resource X i If idle is detected (ie no signal is sent), the sending of the "resource busy of primary user i" signal is stopped.

[0102] Step 5: Generate access rules for the primary user, such as Figure 3 as shown in .

[0103] In this step, for primary user i, when a message arrives, it is allocated resource X i After sending, wait for receiving ACK signal from the base station.

[0104] In this step, if primary user i does not receive ACK, the above process is repeated until an ACK signal is received or the primary user i is terminated by a higher-level protocol.

[0105] Step 6: Generate access rules from users, such as Figure 4 as shown in .

[0106] In this step, assuming that slave user j is associated with master user i, when a message arrives, first monitor whether the base station sends a "master user i's resource busy" signal. If the signal is received, wait until the signal is no longer received.

[0107] In this step, user j allocates resource X iThe base station randomly selects a time slot and then transmits the corresponding signal. After sending, it waits to receive the ACK signal from the base station.

[0108] In this step, if the ACK signal from the base station is not received, the slave user j stops transmitting and then monitors whether the base station sends a "master user i's resource is busy" signal. If the signal is monitored, it waits until the signal is no longer received.

[0109] In this step, user j allocates resource Y j After sending, wait for receiving ACK signal from the base station.

[0110] In this step, if user j does not receive an ACK signal from the base station, the above process is repeated until an ACK signal is received or the process is terminated by a higher-level protocol.

[0111] Step 6: Perform wireless communication based on the rule of the base station, the access rule of the primary user and the access rule of the secondary user.
