Description

[0001] This disclosure is a divisional application of the invention patent application with the application number 201980000073.1 and the invention title "Method, apparatus, device and system for using power-saving signal patterns" filed on January 22, 2019. Technical Field

[0002] This disclosure relates to the field of communications, and particularly to a method, apparatus, device and system for using power-saving signal spectra. Background Art

[0003] In Release 15 of the Third Generation Partnership Project (3GPP), for the Narrow Band Internet of Things (NB-IoT) and enhanced Machine Type Communication (eMTC) projects, Wake-Up Signaling (WUS) and Go-To-Sleep Signaling (GTS) were introduced.

[0004] Among them, WUS is a low-power detection signal, usually placed before the monitoring time of the Physical Downlink Control Channel (PDCCH). If the UE detects WUS, it means that it needs to monitor the PDCCH; if the UE does not detect WUS, it skips the monitoring of the PDCCH. WUS can also appear at a certain period, and the UE wakes up and monitors WUS according to a fixed period. GTS explicitly makes the UE sleep for a period of time. The patterns of WUS and GTS are collectively referred to as power-saving signal patterns. Summary of the Invention

[0167] Here, the exemplary embodiments will be described in detail, and the examples are shown in the drawings. When the following description refers to the drawings, unless otherwise indicated, the same numbers in different drawings represent the same or similar elements. The implementation manners described in the following exemplary embodiments do not represent all implementation manners consistent with the present disclosure. On the contrary, they are merely examples of devices and methods consistent with some aspects of the present disclosure as detailed in the appended claims.

[0168] The communication systems and service scenarios described in the embodiments of the present disclosure are for more clearly illustrating the technical solutions of the embodiments of the present disclosure, and do not constitute a limitation on the technical solutions provided by the embodiments of the present disclosure. Those of ordinary skill in the art will know that with the evolution of communication systems and the emergence of new service scenarios, the technical solutions provided by the embodiments of the present disclosure are equally applicable to similar technical problems.

[0169] In an optional embodiment, the embodiments of the present disclosure can be applied to a communication system supporting IoT and eMTC. The communication system may include: an access network 12 and a terminal 13.

[0170] The access network 12 includes several access network devices 120. The access network devices 120 communicate with the core network device 110 through a certain interface technology, such as the S1 interface in the LTE system and the NG interface in the 5G NR system. The access network device 120 may be a base station, which is a device deployed in the access network to provide wireless communication functions for terminals. The base station may include various forms of macro base stations, micro base stations, relay stations, access points, etc. In systems adopting different radio access technologies, the names of the devices with base station functions may be different. For example, in the LTE system, it is called eNodeB or eNB; in the 5G NR system, it is called gNodeB or gNB. With the evolution of communication technologies, the name "base station" may change. For the convenience of the embodiments of the present disclosure, the above-mentioned devices providing wireless communication functions for terminals are collectively referred to as access network devices.

[0171] The terminal 13 may include various handheld devices, vehicle-mounted devices, wearable devices, computing devices or other processing devices connected to a wireless modem with wireless communication functions, as well as various forms of user equipment (UE), mobile station (MS), terminal (English: terminal device), and so on. For ease of description, the devices mentioned above are collectively referred to as terminals. The access network device 120 communicates with the terminal 13 through a certain air interface technology, such as the Uu interface.

[0172] Figure 1 Shown is a communication system diagram of an application scenario in an embodiment. In the embodiments of the present disclosure, a method for using a power-saving signal spectrum is provided for different types of service listening requirements to solve the problem that the power-saving signal pattern will increase the scheduling delay of the UE and cannot meet the delay requirements of some types of services.

[0173] The present disclosure configures trigger conditions and failure conditions for the user equipment not to use the power-saving signal spectrum through the base station, realizes the switching of different listening modes, enables the listening mode based on the power-saving signal spectrum in the usage scenarios with high power consumption requirements; switches the listening mode in the application scenarios with high delay requirements and enables other listening modes based on the non-power-saving signal spectrum.

[0174] Figure 2 It is a flowchart of a method for using a power-saving signal spectrum shown according to an exemplary embodiment. This method can be applied to Figure 1 the communication system shown. This method may include the following steps.

[0175] In step 201, the access network device sends a trigger condition to the terminal.

[0176] Optionally, the way for the access network device to send the trigger condition to the terminal can be a broadcast message or a dedicated signaling.

[0177] In step 202, the terminal obtains the trigger condition.

[0178] Correspondingly, the terminal receives the trigger condition sent by the access network device through the downlink channel.

[0179] In step 203, the terminal determines whether the trigger condition is met.

[0180] Optionally, the trigger condition includes the condition for stopping using the power-saving signal spectrum.

[0181] In step 204, the terminal determines whether the trigger condition is met.

[0182] Optionally, the terminal determines whether its own state meets the trigger condition.

[0183] The triggering condition is a condition used to indicate to the terminal to stop using the power-saving signal pattern. The triggering condition is used to indicate that there is a service with high latency requirements. High latency requirements refer to services with latency requirements higher than the condition. For example, it can be ultra-reliable low-latency communication (ULLC).

[0184] In step 205, when the terminal meets the triggering condition, it stops using the power-saving signal pattern.

[0185] In summary, in the method provided in this embodiment, in a system introducing a power-saving signal pattern, a triggering signal is set between the terminal and the access network device or within the terminal itself, enabling the terminal to select a listening mode between PDCCH trigger-based listening triggered by the power-saving signal pattern and other listening not triggered by the power-saving signal pattern. On the one hand, it ensures that the terminal can operate with low power consumption; on the other hand, when there are latency requirements, the listening mode is changed to other listening modes not triggered by the power-saving signal pattern, which can meet the low-latency requirements. By introducing a triggering signal to switch the listening mode, the present disclosure not only ensures the low-power operation mode of the device but also can meet the application scenarios with low-latency requirements.

[0186] Based on Figure 2 the embodiments, there are two configuration methods for configuring the triggering condition. One is to configure it in a broadcast manner, and the other can be to configure it in a dedicated signaling manner; among them, for configuring in a broadcast manner, reference can be made to Figure 3 the embodiments, and for the dedicated signaling configuration method, reference can be made to Figure 4 the embodiments.

[0187] Figure 3 is a flowchart of a method for using a power-saving signal pattern shown according to another exemplary embodiment. It includes at least the following steps:

[0188] Step 301, the access network device sends a broadcast message.

[0189] The access network device periodically sends a broadcast message to the terminal through the broadcast channel.

[0190] Optionally, the broadcast message includes multiple System Information Blocks (SIBs). Optionally, the triggering condition is carried in SIB X (such as SIB 4) and is periodically sent within the cell.

[0191] The triggering condition is a condition used to trigger the non-use (or stop using) of the power-saving signal pattern. The triggering condition is used to indicate that there is a service with high latency requirements, and high latency requirements refer to latency requirements higher than a preset condition.

[0192] Step 302, the terminal obtains the triggering condition in the broadcast message.

[0193] Optionally, the triggering condition includes at least one of the following conditions:

[0194] When the terminal initiates an RA request, it is in a state of waiting for a response message;

[0195] After the terminal initiates an SR request;

[0196] After the terminal initiates a BSR request for a specified logical channel, or after the terminal initiates a BSR request for a specified logical channel group;

[0197] After the terminal initiates a measurement report request;

[0198] After the terminal initiates a reconstruction report request;

[0199] After the T1 time after the terminal receives a downlink data grant and there is a downlink decoding error; T1 is the time interval from when the terminal receives the downlink data grant to when it expects a downlink data grant retransmission;

[0200] After the T2 time after the terminal receives an uplink data grant; T2 is the time interval from when the terminal receives the uplink data grant to when it expects an uplink data grant retransmission or a new transmission;

[0201] After the terminal detects that there is an authorization corresponding to itself in the power saving signal indication;

[0202] After the terminal detects that there is an authorization corresponding to itself in the PDCCH.

[0203] In step 303, the terminal determines whether the triggering condition is met.

[0204] Optionally, the triggering condition includes a condition for stopping using the power saving signal map.

[0205] In step 304, when the triggering condition is met, the terminal stops using the power saving signal map.

[0206] Optionally, when the terminal determines that the triggering condition in the broadcast message is met, the terminal stops using the power saving signal map monitoring.

[0207] The PDCCH is used to send information for the downlink (Downlink Control Information, DCI), and the information it transmits includes common control information (system information, paging information, etc.) and user-specific information.

[0208] Optionally, the power saving signal map includes: the map of the Wake-Up Signaling (WUS) and the map of the Go-To-Sleep Signaling (GTS); wherein,

[0209] The map of WUS includes: start time offset and period;

[0210] The map of GTS includes: sleep start time and sleep duration.

[0211] Optionally, other listening methods not triggered based on the power saving signal pattern can be PDCCH, or Discontinuous Reception (DRX). WUS can be used together with DRX. When WUS fails, DRX can work alone.

[0212] In summary, for the method provided in this embodiment, when the access network device needs to send trigger conditions to multiple or all terminals in the cell, it can use broadcast messages to configure trigger conditions for multiple terminals at one time, reducing the number of transmissions of the access network device.

[0213] In another possible embodiment, the access network device can also use other methods to send trigger conditions, such as Figure 4 As shown, a flowchart of another method for using the power saving signal map is provided. The method includes the following steps.

[0214] In step 401, the access network device sends dedicated signaling to the terminal.

[0215] The dedicated signaling is the command information sent by the access network device to the specified terminal. The dedicated signaling includes the C-RNTI and CCE information used for CRC check with the terminal.

[0216] Parts of steps 402 to 404 are the same as the content of the embodiment where Figure 3 is located, and this embodiment will not be elaborated here.

[0217] In summary, for the method provided in this embodiment, when the access network device needs to send trigger conditions to one or more specified terminals, it can be sent in the form of dedicated signaling, avoiding affecting other terminals in the cell.

[0218] In another possible embodiment, the triggering condition can also be pre-determined by a communication protocol. During operation, the terminal determines in real time based on its own status whether the pre-configured triggering condition inside it is met. If the triggering condition is met, the terminal stops using the power-saving signal map, and the device adopts other listening methods that are not triggered based on the power-saving signal pattern; if the condition is not met, the terminal does not change the listening method and still adopts the PDCCH trigger-based listening using the power-saving signal pattern.

[0219] In summary, in the method provided in this embodiment, the triggering condition is pre-defined inside the terminal without changing the access network device, and the terminal determines in real time based on its own status whether the triggering condition is met and selects the listening method by itself, avoiding over-reliance on the access network device and making the setting more flexible.

[0220] In a possible embodiment, when the triggering condition is used to make the terminal in other listening modes that are not triggered based on the power-saving signal pattern, a failure condition can also be introduced to change the listening mode of the terminal. For example, changing from other listening states that are not triggered based on the power-saving signal pattern to the listening mode based on the power-saving signal map. Figure 5 The flowchart of a method for using a power-saving signal map in an embodiment provided by the present disclosure is shown. The method includes the following steps:

[0221] Step 501, the access network device sends a triggering condition.

[0222] Optionally, the triggering condition can be sent to the terminal in the form of a broadcast message or dedicated signaling.

[0223] Step 502, the terminal obtains the triggering condition.

[0224] Optionally, the terminal obtains the triggering condition sent by the access network device or reads the pre-defined triggering condition.

[0225] Step 503, the terminal determines whether the triggering condition is met.

[0226] Optionally, the triggering condition includes at least one of the conditions in step 302.

[0227] Step 504, when the triggering condition is met, the terminal stops using the power-saving signal map.

[0228] Step 505, the access network device sends a failure condition.

[0229] The failure condition is used to indicate to the terminal the condition for resuming the use of the power-saving signal map. The failure condition is used to indicate that there is no service with high latency requirements currently.

[0230] A high latency requirement refers to services with a latency requirement higher than a certain condition. The failure condition is that the configured terminal switches from other listening states not triggered by the power saving signal pattern to the power saving signal pattern listening mode. The failure condition and the triggering condition are corresponding to each other. When the terminal currently has services with high latency requirements, it meets the triggering condition, and when there are no services with high latency requirements or the services with high latency requirements end, it meets the failure condition.

[0231] Optionally, the access network device can send the failure condition in the same way as sending the triggering condition. It can send the failure condition to the terminals in the cell by means of broadcasting, or send it to specific terminals by means of dedicated signaling.

[0232] Step 506, the terminal obtains the failure condition.

[0233] Optionally, the terminal can obtain the failure condition from the broadcast message or dedicated signaling sent by the access network device, and can also pre-define the failure condition in the terminal. The terminal determines whether it meets the failure condition according to its own status at any time.

[0234] Step 507, the terminal determines whether it meets the failure condition.

[0235] Optionally, the failure condition includes at least one of the following conditions:

[0236] The terminal sets a timer with a duration T3 after the triggering condition takes effect, and the timer times out;

[0237] The terminal receives an authorization response message, and the authorization response is a response message from the access network device to the terminal's SR request;

[0238] The terminal receives a reconstruction response message, and the reconstruction response is a response message from the access network device to the terminal's reconstruction request;

[0239] The terminal receives a cell handover command, and the cell handover command is generated by the access network device after receiving the measurement report request from the terminal;

[0240] The terminal receives a msg4 message scrambled with C-RNTI, and the msg4 message is generated by the access network device after receiving the RA request from the terminal;

[0241] The terminal receives the expected uplink data retransmission or new transmission authorization information;

[0242] The terminal receives the expected downlink data retransmission authorization information.

[0243] Step 508, when the failure condition is met, resume using the power saving signal pattern.

[0244] In summary, in the method provided in this embodiment, the failure condition can be sent in the form of a broadcast message or in the form of a dedicated signaling. When the access network device needs to send the failure condition to multiple or all terminals in the cell, it can send the failure condition at one time, reducing the number of transmissions of the access network device. When the access network device needs to send the failure condition to a specific device, it can be sent in the form of dedicated signaling, and the access network device can accurately find the terminal, avoiding affecting other devices in the cell.

[0245] In another optional embodiment, the access network device configures the trigger condition and the failure condition at the same time, as Figure 6 shown, including:

[0246] Step 601, the access network device sends the trigger condition and the failure condition.

[0247] Optionally, the access network device sends the trigger condition and the failure condition to the terminal at the same time, and the sending method can be in the form of broadcast or in the form of dedicated signaling.

[0248] Step 602, the terminal obtains the trigger condition and the failure condition sent by the access network device.

[0249] When the terminal is in the power-saving signal pattern listening mode, the terminal enters Step 602 to obtain the trigger condition, Step 603 to determine whether the trigger condition is met, and Step 604. If the terminal meets the trigger condition, it stops using the power-saving signal pattern. When the terminal is in other listening modes that are not triggered based on the power-saving signal pattern, the terminal enters Step 605 to obtain the failure condition, Step 606 to determine whether the failure condition is met, and Step 607. If the terminal meets the failure condition, it resumes using the power-saving signal pattern mode.

[0250] Optionally, the trigger condition and the failure condition in this embodiment are the same as the trigger condition and the failure condition described in the above embodiment, so they will not be elaborated in this embodiment.

[0251] In summary, the access network device sends the trigger condition and the failure condition at the same time, reducing the number of times the terminal is woken up to obtain the trigger condition or the failure condition, thereby reducing unnecessary power consumption and increasing the working time of the terminal.

[0252] In another possible embodiment, the failure condition can also be pre-defined and set in the terminal. The terminal pre-defines the failure condition in the terminal without changing the access network device, and determines whether the failure condition is met according to its own state and selects the listening method by itself, thereby reducing the signaling interaction between the terminal and the access network device.
