Detailed ways

Exemplary embodiments will be described in detail herein, examples of which are shown in the accompanying drawings. When the following description refers to the drawings, the same numbers in different drawings represent the same or similar elements unless otherwise indicated. The embodiments described in the following exemplary embodiments do not represent all embodiments consistent with the present disclosure. Instead, they are merely examples of devices and methods consistent with some aspects of the present disclosure as detailed in the appended claims.

In the related art, Rel-18 introduces a low-power WUS, which can be received by a separate receiver. The user equipment needs to use a main transceiver to process downlink information and uplink information. The user equipment can also use a main receiver to process downlink information. Both the main receiver and the main transceiver can be called a main radio. If the user equipment receives a WUS signal indicating that the user equipment wakes up, the user equipment will turn on the main transceiver for sending, receiving and processing downlink/uplink information, or turn on the main receiver for receiving and processing downlink information; if the WUS is not received, or the WUS indicates not to wake up, the user equipment will maintain the sleep state of the main transceiver/main receiver, where WUS can be used in RRC (Radio Resource Control) connected state or RRC idle state. In the RRC connected state and RRC idle state, in order to keep the user equipment closed for a long time, the receiver receiving the WUS needs to complete the synchronization function, which can be achieved by monitoring SSB (Synchronization Signal and PBCH block), or the WUS itself also has the function of achieving synchronization.

The introduction of low-power WUS signals provides a method for enabling user equipment to adaptively monitor carriers according to the arrival of services, so that when the network equipment has a service need to page the user equipment, the user equipment can send and receive data in a timely manner. The user equipment may transmit data on one or more carriers. For the user equipment, the user equipment does not know which carriers to monitor. If all carriers are monitored, the user equipment will increase a lot of power consumption. If the carrier on which the user equipment has no data transmission is monitored, the user equipment will be unable to send and receive data in a timely manner, thereby increasing the delay in sending and receiving data by the user equipment.

In addition, the timing of the user equipment monitoring the carrier is also particularly important. Starting to monitor too early will cause the user equipment to increase a lot of power consumption, and starting to monitor too late will cause the user equipment to be unable to send and receive in time. For example, a low-power wake-up signal can be used to wake up the user equipment or put the user equipment into a lighter sleep state, and the time required for the main radio of the user equipment to wake up from different sleep states is different. For the user equipment to wake up from a lighter sleep state, the main radio of the user equipment needs to wake up in a shorter time. If the user equipment starts to monitor the carrier late, it may cause the user equipment to delay sending and receiving data; for the user equipment to wake up from a deeper sleep state, the main radio of the user equipment needs to wake up in a longer time. If the user equipment starts to monitor the carrier too early, it may cause the user equipment to increase unnecessary power consumption.

In view of this, an embodiment of the present disclosure provides a carrier sensing method, device, storage medium and communication system, which are explained below in conjunction with the accompanying drawings.

Fig. 2 is a flow chart of a carrier sensing method according to an exemplary embodiment. The carrier sensing method may be executed by a user equipment in the above communication system. Referring to Fig. 2, the carrier sensing method may include:

S201, receiving a wake-up signal.

S202: Monitor the target carrier.

In some embodiments, the wake-up signal can be LP WUS (Low Power Wakeup Signal).

In some embodiments, the network device may directly send the wake-up signal to the user equipment, or the network device may forward the wake-up signal to the user equipment through a forwarding device.

The target carrier is a carrier for realizing data transmission between the user equipment and the network equipment. For example, the carrier may be called a cell.

FIG3 is a flow chart of a carrier monitoring method according to an exemplary embodiment. The carrier monitoring method may be performed by a user equipment in the above communication system. Referring to FIG3 , the step of monitoring the target carrier may include:

S301, monitoring information data of a target carrier.

Among them, information data is data transmitted between user equipment and network equipment, and the services between user equipment and network equipment are realized through the transmitted data.

By monitoring the information data of the target carrier in the above manner, the user equipment can monitor the corresponding information data in a timely manner, ensuring that the user equipment can send and receive data in a timely manner, and realizing timely communication between the user equipment and the network equipment.

FIG4 is a flowchart of a carrier sensing method according to an exemplary embodiment. The carrier sensing method may be executed by a user equipment in the above communication system. Referring to FIG4 , the carrier sensing method may further include:

S401, waking up the main radio or changing the sleep state of the main radio.

In some embodiments, after receiving the wake-up signal, the user equipment may wake up the main radio or change the sleep state of the main radio, that is, the wake-up signal is used to wake up the main radio or change the sleep state of the main radio.

In some embodiments, the main radio may include a main receiver. The main receiver being awakened may be understood as the main receiver being able to receive downlink information. The downlink information here may be, for example, downlink control information and downlink data information.

In some embodiments, the master radio may include a master transceiver. The master transceiver being awakened may be understood as the master transceiver being able to send uplink information and receive downlink information. The uplink information here may be, for example, uplink control information and uplink data information, and the downlink information here may be, for example, downlink control information and downlink data information.

In some embodiments, the main radio may include a main receiver and a main transceiver, wherein the explanation of the main receiver and the main transceiver may refer to the above-mentioned related embodiments, and this embodiment will not be described in detail.

In some embodiments, the sleep state may be, for example, at least one of an ultra-deep sleep state, a deep sleep state, a light sleep state, a micro sleep state, and a super micro sleep state, and the sleep levels of the ultra-deep sleep state, the deep sleep state, the light sleep state, the micro sleep state, and the super micro sleep state decrease in sequence. The change in the sleep state may be a change caused by a step-by-step decrease in the sleep level, where the step-by-step decrease may be understood as the sleep levels of the sleep states before and after the change are adjacent and the sleep level after the change is lower than the sleep level before the change, for example, from a deep sleep state to a light sleep state, and for another example, from a micro sleep state to an ultra-micro sleep state, and so on. The change in sleep state may be caused by a step-by-step decrease in sleep level. The step-by-step decrease here may be understood as the sleep levels of the sleep states before and after the change are non-adjacent and the sleep level after the change is lower than the sleep level before the change, for example, from a deep sleep state to a light sleep state, or from a light sleep state to a super light sleep state, and so on.

It is worth noting that when the user device has no data to transmit, the wake-up signal can be used to notify the user device not to wake up, so as to reduce the power consumption of the user device; when the user device has data to transmit, the wake-up signal can be used to notify the user device to wake up or change the sleep state. Waking up the main radio here means waking up the user device, and changing the sleep state of the main radio here means changing the sleep state of the user device.

Through the above scheme, the wake-up signal is used to wake up the main radio so that the user device can send and receive information data. The wake-up signal is used to change the sleep state of the main radio so that the user device is in a lighter sleep state, reducing the time it takes for the main radio to be woken up later, thereby reducing the delay in sending and receiving data by the user device.

FIG5 is a flowchart of a carrier sensing method according to an exemplary embodiment. The carrier sensing method may be executed by a user equipment in the above communication system. Referring to FIG5 , the carrier sensing method may include:

S501, receiving a wake-up signal.

S502: Wake up the main radio or change the sleep state of the main radio.

S503: monitor the target carrier.

The implementation process of S501, S502 and S503 can refer to the above-mentioned related embodiments, and this embodiment will not be repeated here. In addition, this embodiment does not limit the implementation order of S502 and S503, and S503 can be executed first, and then S502.

Through the above scheme, the wake-up signal is used to wake up the main radio so that the user device can send and receive information data, or the wake-up signal is used to change the sleep state of the main radio so that the user device is in a lighter sleep state, reducing the wake-up time, thereby reducing the delay in sending and receiving data of the user device.

FIG6 is a flowchart of a carrier monitoring method according to an exemplary embodiment. The carrier monitoring method may be executed by a user equipment in the above communication system. Referring to FIG6 , the step of monitoring the target carrier may include:

The wake-up signal may include carrier indication information, and the carrier indication information indicates a target carrier for the user equipment to monitor information data.

The explanation of the wake-up signal and information data here can refer to the above-mentioned related embodiments, and this embodiment will not be described in detail here.

Through the above scheme, by monitoring information data on the carrier indicated in the carrier indication information of the wake-up signal, the problem of user equipment increasing power consumption by monitoring other redundant carriers can be avoided. In addition, the carrier indication information can be used to achieve flexible setting of the target carrier, thereby improving the flexibility of carrier monitoring.

FIG7 is a flowchart of a carrier monitoring method according to an exemplary embodiment. The carrier monitoring method may be executed by a user equipment in the above communication system. Referring to FIG7 , the step of monitoring the target carrier may include:

S701, monitoring information data on a carrier that receives a wake-up signal.

Among them, the explanation of the wake-up signal and information data here can refer to the above-mentioned related embodiments, and this embodiment will not be repeated here.

It is worth noting that the user equipment has a higher probability of successfully receiving information data on the carrier that receives the wake-up signal.

In this way, the probability of successfully and timely receiving the information data by monitoring the information data on the carrier receiving the wake-up signal is higher, thereby further reducing the delay of the user equipment in sending and receiving data.

FIG8 is a flowchart of a carrier monitoring method according to an exemplary embodiment. The carrier monitoring method may be executed by a user equipment in the above communication system. Referring to FIG8 , the step of monitoring the target carrier includes:

S801: Monitor information data on all carriers configured for user equipment.

The explanation of the information data here can refer to the above-mentioned related embodiments, and this embodiment will not be described in detail here.

It is worth noting that the user equipment generally has a higher probability of successfully transmitting and receiving data on the configured carrier.

In this way, the probability of successfully and timely receiving the information data by monitoring the information data on all carriers configured by the user equipment is higher, thereby further reducing the delay of the user equipment in sending and receiving data.

FIG9 is a flowchart of a carrier monitoring method according to an exemplary embodiment. The carrier monitoring method may be performed by a user equipment in the above communication system. Referring to FIG9 , the step of monitoring the target carrier may include:

S901, monitoring information data on the carrier monitored by the user equipment before going into sleep mode.

It is worth noting that the carrier monitored by the user equipment before going to sleep is generally the carrier on which the user equipment successfully and timely receives information data.

In this way, the probability of successfully and timely receiving the information data by monitoring the information data on the carrier monitored by the user equipment before going to sleep is higher, thereby further reducing the delay of the user equipment in sending and receiving data.

FIG10 is a flowchart of a carrier monitoring method according to an exemplary embodiment. The carrier monitoring method may be performed by a user equipment in the above communication system. Referring to FIG10 , the step of monitoring the target carrier may include:

S1001: Monitor information data on a first carrier configured by user equipment.

The first carrier may be one or more of an anchor carrier, a primary cell carrier, and a primary and secondary cell carrier.

Among them, the anchor carrier for the frequency division duplex (FDD) system refers to the carrier that the UE considers to transmit the NB-IoT-related physical broadcast channel (NPBCH), primary synchronization signal (NPSS)/secondary synchronization signal (NSSS), system information block (SIB-NB), etc.; the primary cell carrier is the carrier that carries signaling and can manage other carriers; the primary and secondary cell carriers are used to expand the bandwidth and enhance the rate, and can be managed by the primary cell carrier. The management here can be addition and/or deletion.

Through the above solution, the probability of successfully and timely receiving the information data by monitoring the information data on the first carrier configured by the user equipment is higher, thereby further reducing the delay of the user equipment in sending and receiving data.

In some embodiments, the carrier indication information may include at least one carrier indication field, and the decimal value of the carrier indication field corresponds to a carrier index. The carrier indication field may be represented by 2 or 3 bits of data, and the decimal value of each carrier indication field corresponds to a carrier index. Through the carrier index, the corresponding carrier may be queried, so that the user equipment may monitor information data on the carrier corresponding to the carrier index.

In some embodiments, the carrier indication information may include an index of a carrier combination. In other embodiments, the carrier indication information may include a carrier index, wherein the physical meaning of the carrier index and the index representation are consistent, and the corresponding carrier can be queried through the carrier index or index, and both the carrier index and the index can be represented by a decimal value. Refer to the corresponding relationship between the carrier index/index and the carrier shown in the following table:

In the above table, for carrier index 0, the corresponding carrier is a single carrier (CC0); for index 10, the corresponding carrier is a combination of carriers, that is, multiple carriers (CC0, CC1 and CC2), which are reserved for characterizing other carriers. The carrier combination in the above table can be understood as including at least one carrier.

In some embodiments, the carrier indication information may include at least one carrier identifier, wherein each carrier identifier uniquely corresponds to a carrier, and through the carrier identifier, the user equipment may monitor information data on the carrier corresponding to the carrier identifier.

In some embodiments, the carrier indication information may include at least one of at least one carrier indication field, an index of a carrier combination, a carrier index, and at least one carrier identifier. The specific implementation of this embodiment may refer to the above-mentioned related embodiments, and this embodiment will not be described in detail here.

In some embodiments, the first carrier may be configured by at least one of the following signaling:

Downlink Control Information (DCI) signaling;

Media Access Control (MAC) signaling;

Media Access Control Element (MAC CE) signaling;

Radio Resource Control (RRC) signaling.

Among them, the explanation of downlink control information signaling, media access control signaling, media access control control unit signaling and radio resource control signaling can be referred to the relevant technology, and this embodiment will not be repeated here.

FIG11 is a flowchart of a carrier monitoring method according to an exemplary embodiment. The carrier monitoring method may be executed by a user equipment in the above communication system. Referring to FIG11 , the step of monitoring the target carrier may include:

S1101, monitoring information data of a target carrier at a first time node.

In some embodiments, the target carrier may be a carrier indicated by the carrier indication information. The explanation of the carrier indication information may refer to the above-mentioned related embodiments, and this embodiment will not be described in detail here.

In some other embodiments, the target carrier may be a carrier that receives the wake-up signal. The explanation of the carrier that receives the wake-up signal may refer to the above-mentioned related embodiments, which will not be described in detail in this embodiment.

In some other embodiments, the target carrier may be all carriers configured for the user equipment. The explanation of all carriers configured for the user equipment may refer to the above-mentioned related embodiments, and this embodiment will not be described in detail.

In some other embodiments, the target carrier may be a carrier monitored by the user equipment before it goes to sleep. The explanation of the carrier monitored by the user equipment before it goes to sleep can refer to the above-mentioned related embodiments, which will not be described in detail in this embodiment.

In some other embodiments, the target carrier may be the first carrier configured by the user equipment. The explanation of the first carrier may refer to the above-mentioned related embodiments, and this embodiment will not be described in detail here.

As can be seen from the foregoing, the timing of the user equipment monitoring the carrier is also particularly important. Starting monitoring too early will cause the user equipment to increase power consumption, while starting monitoring too late will cause the user equipment to be unable to send and receive in time.

Therefore, through the above scheme, the first time node can be flexibly set, and the information data of the target carrier can be monitored at the first time node, so as to realize the flexible configuration of the time for the user device to monitor the carrier, thereby avoiding the situation where starting monitoring too early will cause the user device to increase a lot of power consumption and starting monitoring too late will cause the user device to be unable to send and receive in time.

FIG12 is a flowchart of a carrier monitoring method according to an exemplary embodiment. The carrier monitoring method may be performed by a user equipment in the above communication system. Referring to FIG12 , the step of monitoring the target carrier may include:

S1201, monitoring information data of a target carrier after a first time duration at a first time node.

Through the above scheme, the first time node and the first duration can be flexibly set, and the information data of the target carrier can be monitored after the first duration of the first time node, thereby realizing flexible configuration of the time for the user device to monitor the carrier, thereby avoiding the situation where starting monitoring too early will cause the user device to increase a large amount of power consumption and starting monitoring too late will cause the user device to be unable to send and receive in time.

In some embodiments, the first time node may be a time node when the user equipment receives a wake-up signal.

Among them, the explanation of the wake-up signal can refer to the above-mentioned related embodiments, and this embodiment will not be repeated here.

As can be seen from the foregoing, for a user device in a lighter sleep state, the wake-up time is shorter, for example, changing from a lighter sleep state to a super lighter sleep state. Therefore, the target carrier can be monitored at the time when the user device receives the wake-up signal.

In this way, it can be ensured that the user equipment can enter the monitoring of the target carrier in time, thereby reducing the delay of the user equipment in sending and receiving data.

In some embodiments, the first time node may be a time node at which the user equipment successfully decodes the received wake-up signal.

As can be seen from the foregoing, the awakening time is different for different sleep levels. For some sleep states at a medium sleep level, the target carrier can be monitored at the time point when the user equipment successfully decodes the received wake-up signal.

In this way, it is possible to ensure that the user equipment can enter the monitoring of the target carrier in time and avoid power consumption caused by premature monitoring of the user equipment.

In some embodiments, the first time node may be a time node at which the primary radio is awakened.

Among them, the explanation about the main radio can refer to the above-mentioned related embodiments, and this embodiment will not be described in detail here.

As can be seen from the foregoing, for a user equipment in a relatively shallow sleep state, its awakening time is very short, for example, awakening from a super shallow sleep state, and therefore, the target carrier can be monitored at the time point when the main radio is awakened.

In this way, the power consumption of the user equipment can be reduced.

In some embodiments, the first time node may be a time node at which the sleep state of the primary radio changes.

As can be seen from the foregoing, the time required for the main radio of the user equipment to wake up from different sleep states is different. It is worth noting that the time required for the user equipment to wake up from a lighter sleep state is less than the time required for the user equipment to wake up from a deeper sleep state.

Therefore, in order to solve the problem of delayed data transmission and reception by the user equipment when the user equipment wakes up from a shallow sleep state and starts monitoring the carrier late, the target carrier can be monitored starting from the time point when the sleep state of the main radio changes, thereby reducing the delay in data transmission and reception by the user equipment.

In some embodiments, the first time node may be one or more of a time node when the user equipment receives a wake-up signal, a time node when the user equipment successfully decodes the received wake-up signal, a time node when the main radio is awakened, and a time node when the sleep state of the main radio changes.

In some embodiments, the first duration in the above-mentioned related embodiments may be configured by the network device to the user equipment.

In some embodiments, the first duration in the above-mentioned related embodiments may be predefined in the protocol.

In some embodiments, the first duration in the above-mentioned related embodiments may be set by the user equipment and reported to the network device.

In some embodiments, the information data in the above-mentioned related embodiments may be downlink control information.

The downlink control information refers to the downlink information sent by the network device to the terminal. The downlink control information can be transmitted using a downlink channel, such as a physical downlink control channel (PDCCH).

In some embodiments, the information data in the above-mentioned related embodiments may be downlink data information.

The downlink data information refers to the downlink information sent by the network device to the terminal. The downlink data information can also be transmitted using a downlink channel, where the downlink channel can be, for example, a physical downlink shared channel (PDSCH).
