Description

TECHNICAL FIELD

[0001] The present disclosure relates to the technical field of wireless communication, and in particular, to a communication method, system, terminal, node device, network device and related device. BACKGROUND

[0002] In a communication system (such as a 5G / 6G communication system), when a terminal is at the edge of a cell or in a signal shielding area, the traditional PRACH (Physical Random Access Channel) access process will have frequent access failures due to poor channel quality. At present, the solution adopted in the related art is to increase the density of base stations or deploy some relay devices, which has the problems of high cost and high energy consumption. By using a reconfigurable intelligent surface (RIS), a network relay device or the like as a network node to forward the signals of the base station, it has the characteristics of low cost and low power consumption, and becomes a key means to enhance network coverage.

[0003] However, if the network node continuously monitors the access request from the terminal, the forwarding module in the network node is in an active state for a long time, which not only increases the power consumption of the network node, but also causes signal interference to users in adjacent frequency and adjacent cells. In addition, when the terminal is at the edge of a cell or in a signal shielding area, it is difficult to directly capture the SSB (Synchronization Signal Block) of the base station to initiate PRACH access to the cell, and dynamic beam sweeping requires multiple interactions between the base station and the terminal, further increasing the access delay and causing problems such as repeated attempts and rapid increase in energy consumption. Therefore, there is an urgent need for a low-power network node assisted communication method.

[0004] It should be noted that the information disclosed in the above background section is only used to strengthen the understanding of the background of the present disclosure, and therefore can include information that does not constitute prior art known to those of ordinary skill in the art.

[0145] In some embodiments, the preset communication conditions are that the terminal cannot access the network or the communication service quality is not up to the preset quality condition.

[0146] Figure 10 This diagram illustrates a method for low-power wake-up network node-assisted communication according to an embodiment of the present disclosure, such as... Figure 10 As shown, the specific steps include the following:

[0147] S102, The terminal determines that it is in a situation of poor communication quality / unable to access the cell;

[0148] S104, The terminal sends the first information to the network node to wake up the network node;

[0149] The S106 network node resumes its active state from dormant state and forwards the first information to the network device;

[0150] The S108 network device determines the priority of terminal service requests;

[0153] The S114 terminal measures the beam quality and re-initiates PRACH access;

[0154] The S116 terminal completes PRACH access and reports beam information;

[0155] S118, End.

[0156] As can be seen, the low-power wake-up network node assisted communication method provided in this embodiment of the present disclosure can solve the problem of fast and energy-saving access recovery of the terminal in weak signal or access failure scenarios by triggering the activation of the dormant network node through the LP-WUS signal (low-power wake-up signal) and forwarding the base station beam information on demand.

[0157] Below, we will provide a specific example, taking a 5G user at the cell edge attempting to access a nearby macro base station (network device). When a 5G user at the cell edge attempts to access a nearby macro base station, due to factors such as distance and penetration loss, they face problems such as low RSRP and inability to access the network. This can result in multiple failed attempts to initiate PRACH random access, leading to poor service quality for the user.

[0158] The low-power wake-up network node assisted communication method provided in this embodiment of the disclosure can achieve rapid terminal access through the following steps:

[0159] 1) The terminal generates a WUS signal (first information), including: re-initiating a PRACH access request, the service type is voice service, it has high priority, and the terminal identifier.

[0160] 2) In low-power mode, the signal is sent once within the wake-up window. At this time, due to factors such as shadow occlusion, the WUS signal cannot be sent to the macro base station, but the network node communication module detects the low-power wake-up signal sent by the terminal and sends it to the macro base station.

[0161] 3) After parsing the first information, the base station performs the following operations: ① Confirms that the service priority requested by this terminal is the second highest in the current list; ② Allocates time and frequency resources to the terminal and dynamically updates the beam configuration; ③ Sends the second information to instruct the network node to perform beam scanning at the angle and beamwidth.

[0162] 4) The network node receives the second information sent by the base station, activates the forwarding module, and generates a forwarding beam.

[0163] 5) The terminal detects the SSB beam forwarded by the network node and sends a preamble on the corresponding time and frequency resources. The base station responds quickly, the terminal accesses successfully, the RRC connection is established, and the terminal transmits voice service data.

[0164] The low-power wake-up network node-assisted communication method provided in this embodiment of the present disclosure can bring the following significant benefits in practical applications:

[0165] ① Significantly reduce network node power consumption: By using a forwarding module that is in sleep mode by default, it is only activated when a low-power wake-up signal is received, avoiding continuous monitoring of power consumption and extending node battery life (especially suitable for passive / energy-saving nodes).

[0166] ② Improve access success rate in weak signal scenarios: When the terminal cannot access the network or the service quality is poor, it directly triggers the network node to forward the base station beam information (SSB), which helps the terminal to quickly complete beam scanning and PRACH access, thus solving the coverage blind spot problem.

[0167] ③ Optimize network resource scheduling: Base stations decide on access procedures based on terminal service priorities, dynamically control the activation of node data forwarding modules and beam parameters (such as width / pattern), and achieve a balance between energy efficiency and service quality.

[0168] Based on the same inventive concept, this disclosure also provides a terminal, as described in the following embodiments. Since the principle by which this terminal embodiment solves the problem is similar to that of the above-described method embodiments, the implementation of this terminal embodiment can refer to the implementation of the above-described method embodiments, and repeated details will not be elaborated further.
