Description

Communication method and communication device

This application claims priority from a Chinese patent application filed with the Chinese Patent Office on August 31, 2018, with application number 201811015601.4, and with the application name "communication method and communication device", the entire contents of which are incorporated herein by reference.

Technical field

The present application relates to the field of communication, and more particularly, to a communication method and a communication device.

Background technique

In a wireless communication system, a terminal device (user equipment) has two states, one is a connected (CONNECTED) state, and the other is an idle (IDLE) state. The idle state can also be referred to as the sleep state. The connected terminal device has established a connection with the network device and can communicate directly. Terminal devices in idle state cannot directly communicate with network devices.

There is dedicated signaling between the connected terminal equipment and the network equipment. The network equipment will use proprietary signaling, such as radio resource control (RRC) signaling, and medium access layer control unit (medium access control- control element (MAC-CE) signaling or downlink control information (downlink control information (DCI) signaling) to send scheduling information and downlink data to the terminal device. The terminal device can continuously monitor the DCI sent by the network device in the connected state. The DCI indicates how the downlink resources are scheduled, or when the terminal device wants to send uplink data, the DCI indicates on which resources to send the uplink data. After the terminal device detects the DCI, it will receive data or send data on the corresponding resources according to the instructions of the DCI. Generally speaking, the terminal device does not know that the network device has not sent DCI, and can only try to receive DCI in each subframe.

FIG. 1 is an exemplary architecture diagram of a communication system 100 according to an embodiment of the present application. The method in the embodiment of the present application can be applied to the communication system 100 shown in FIG. 1. It should be understood that the communication system 100 to which the methods of the embodiments of the present application can be applied may include more or fewer network devices or terminal devices.

The network device or terminal device in FIG. 1 may be hardware, software divided by functions, or a combination of the two. The network equipment or terminal equipment in FIG. 1 can communicate with each other through other equipment or network elements.

In the communication system 100 shown in FIG. 1, the network device 110 and the terminal devices 101 to 106 form a communication system 100. In the communication system 100, the network device 110 may send downlink data to the terminal device 101 to the terminal device 106. Of course, the terminal device 101 to the terminal device 106 may also send uplink data to the network device 110. It should be understood that the terminal devices 101 to 106 may be, for example, a cellular phone, a smart phone, a portable computer, a handheld communication device, a handheld computing device, a satellite radio, a global positioning system, a PDA, and / or a wireless communication system 100. Any other suitable device for communication.

The communication system 100 may be a PLMN network, a device-to-device (D2D) network, a machine-to-machine (M2M) network, an IoT network, or other networks.

In addition, the terminal devices 104 to 106 may also constitute a communication system. In this communication system, the terminal device 105 may send downlink data to the terminal device 104 or the terminal device 106.

In a wireless communication system, a terminal device can have two states, one is a CONNECTED state, and the other is an IDLE state. The idle state can also be referred to as the sleep state. The connected terminal device has established a connection with the network device and can communicate directly. Terminal devices in idle state cannot directly communicate with network devices.

In addition, the terminal device can also be inactive (inactive) state. The inactive terminal device terminates the connection between the terminal device and the network device. When the terminal device needs to send data or the network side needs the terminal device to receive data, the terminal The device requested a network device to restore the connection. The terminal device can send or receive data in an inactive state.

When no service data needs to be sent or no service data needs to be received, the terminal device can enter an idle state to reduce power consumption. The idle terminal device has not established a connection with the network side. When the network device needs to send service data to the terminal device or the network device needs to report service data to the terminal device, the network device can notify the terminal device by paging, that is, through The paging message indicates that the terminal device needs to send or receive data. The paging message here means that the network device is looking for the terminal device, for example, when the network device has downlink data to send.

Correspondingly, the terminal device also monitors paging messages on specific time-frequency resources. The specific time-frequency resource for the terminal device to monitor the paging message is generally called paging occasion (PO). If the terminal device monitors the downlink control information (DCI) scrambled by the paging wireless network temporary identifier (P-RNTI) on the PO, then the terminal device will indicate at the P-RNTI DCI The resource goes up to receive the paging message. Generally, the paging message carries a list of terminal device identifications. If the terminal device finds that its identity is in the list, the terminal device then initiates random access and attempts to access the network.

After receiving the paging message, the terminal device can enter the connection state under the instruction of the paging message in order to send or receive service data.

A connected terminal device is a state that has established a connection with a network device. There is dedicated signaling between the connected terminal equipment and the network equipment. The network equipment will use proprietary signaling, such as radio resource control (RRC) signaling, and medium access layer control unit (medium access control- control element (MAC-CE) signaling or DCI signaling, sending scheduling information and downlink data to the terminal device. The terminal device can continuously monitor the DCI sent by the network device in the connected state. The DCI indicates how the downlink resources are scheduled, or when the terminal device wants to send uplink data, the DCI indicates on which resources to send the uplink data. After the terminal device detects the DCI, it will receive data or send data on the corresponding resources according to the instructions of the DCI. Generally speaking, the terminal device will detect DCI in the control area of each subframe. At this time, the situation may occur: the network device does not actually send DCI, but the terminal device does not know that the network device does not send DCI, and the terminal device can only Attempting to receive DCI in each subframe causes the terminal device to consume DCI power consumption in subframes where the network device does not send DCI, but fails to detect any valid DCI information.

As a possible implementation manner, a WUS mechanism may be introduced for an idle terminal device. WUS is a sequence. When a terminal device detects such a sequence, the requirements on the receiver are relatively low, because the terminal device does not need to turn on the baseband receiving module when detecting the sequence, it only needs to turn on some circuits in the receiver. In the above-mentioned WUS mechanism, the purpose of WUS is to clearly inform the terminal device whether DCI scrambled by P-RNTI is sent to the terminal device, that is, the terminal device can be woken up when there is DCI scrambled by P-RNTI. For example, if the terminal device detects WUS, it means that DCI scrambled by P-RNTI will be sent later, and then the terminal device will detect DCI scrambled by P-RNTI on subsequent PO; if the terminal device does not detect WUS, then It means that there will be no DCI scrambled by P-RNTI in the future, so the terminal device will not detect DCI on the subsequent PO. In this mechanism, compared to the terminal device directly detecting the P-RNTI scrambled DCI on the PO, the terminal device detecting WUS will save more power. Power consumption, so this mechanism can save power consumption of idle terminal devices.

As a possible implementation manner, a WUS mechanism may be introduced for a terminal device in a connected state. This means that the terminal device in the connected state may receive the WUS signal first, and according to the reception situation of the WUS, the terminal device determines whether DCI is sent subsequently. For example, if the WUS indicates that DCI will not be sent in the future, then the terminal device will not receive DCI in the future. Therefore, the terminal device can save power consumption for detecting DCI.

However, terminal devices in the connected state generally receive and send data. Therefore, it can be considered that the DCI issued by the network device in the connected state is not sparse. Especially when there is downlink large packet data transmission, the downlink DCI transmission may be very dense, Is ongoing. In this case, the terminal device detects WUS before each detection of DCI but consumes more power.

Therefore, the problem that this application hopes to solve is: how can the terminal device reasonably save power in the connected state.

This application proposes a new communication method in response to the above problems. The communication method can be summarized as follows: the terminal device determines whether the terminal device detects wake-up information or scheduling information according to the instruction information. This is a switching mechanism between the wake-up information detection scheme and the scheduling information detection scheme. Whether to switch is determined according to the instruction of the instruction information.

Among them, the wake-up information detection scheme refers to: before the terminal device detects the scheduling information, it first detects the wake-up information, and determines whether the terminal device should detect subsequent scheduling information based on the detection status of the wake-up information; Detect scheduling information without detecting wake-up information in advance.

In the embodiment of the present application, the wake-up information is not limited to the wake-up function disclosed in the name, and may also have a function of letting the terminal sleep. For example, detecting and not detecting wake-up information is the meaning of binomial, which represents the wake-up terminal to detect subsequent scheduling information and indicates that the terminal device does not need to detect subsequent scheduling information; or a mask detected based on the wake-up information. Mask 1 and mask 2 may also have the meaning of binomial; or, according to the information carried by the wake-up information, the meaning of binomial is indicated, and so on.

An example of the wake-up information in this application is WUS. WUS can be a ZC sequence, but it is not limited to WUS must be a sequence. It may also be a signal, a pilot, a signaling, and so on. When the wake-up information is WUS, the implementation of the wake-up information can refer to the WUS in the idle state, which is not repeated here.

In the embodiment of the present application, the connected state is used as the scenario for the description scheme, but the technical solution of the present application is not limited to the connected state, and the technical solution of the present application can also be applied to the inactive state.

One example of the scheduling information in this application is DCI.

In the following, an example of a communication method according to an embodiment of the present application is described using the wakeup information as WUS, the scheduling information as DCI, and the network device as a base station as examples.

FIG. 2 is a schematic flowchart of a communication method according to an embodiment of the present application. It should be understood that FIG. 2 shows the steps or operations of the communication method, but these steps or operations are merely examples. Embodiments of the present application may also perform other operations or variations of each operation in FIG. 2, or not all steps Need to be performed, or these steps can be performed in another order.

S201. The terminal device sends sixth information, and the sixth information is used to indicate whether the terminal device can receive wake-up information in a connected state. Accordingly, the base station receives the sixth information.

The sixth information may be understood as: a switching mechanism for indicating whether the terminal device supports a wake-up information detection scheme and a scheduling information detection scheme.

For example, if the terminal device supports the switching mechanism of the wakeup information detection scheme and the scheduling information detection scheme, the sixth information is used to indicate that the terminal device can receive the wakeup information in the connected state; if the terminal device does not support the wakeup information detection scheme and the scheduling information detection In the scheme switching mechanism, the sixth information is used to indicate that the terminal device cannot receive wake-up information in the connected state.

In some possible implementation manners, the sixth information may be indicated by 1 bit. For example, the sixth information may be True. At this time, the terminal device may be instructed to receive wake-up information in the connected state, that is, the terminal device supports a switching mechanism of a wake-up information detection scheme and a scheduling information detection scheme. True here can be represented by "1".

Similarly, the sixth information may be False. At this time, it may indicate that the terminal device cannot receive the wake-up information in the connected state, that is, the terminal device does not support the switching mechanism of the wake-up information detection scheme and the scheduling information detection scheme. False here can be represented by "0".

By way of example and not limitation, the sixth information may be carried in uplink RRC signaling of the terminal device. For example, the sixth information may be carried in radio resource control connection completion (RRCConnectionComplete) signaling of the terminal device.

Alternatively, the sixth information may be carried in a non-access stratum (NAS) signaling and sent to the core network, and the core network notifies the network device subsequently.

It should be understood that S201 is an optional step. In other words, in the communication method in the embodiment of the present application, not all terminal devices need to execute S201. That is, some or all terminal devices may not report whether they support the switching mechanism of the wake-up information detection scheme and the scheduling information detection scheme. For a terminal device that does not report whether it supports the switching mechanism of the wake-up information detection scheme and the scheduling information detection scheme, optionally, the base station may default the terminal device to support or not support the switching mechanism.

Taking the communication system shown in FIG. 1 as an example, the terminal device 101 may execute S201, send sixth information, and report whether it supports the switching mechanism of the wake-up information detection scheme and the scheduling information detection scheme; the terminal device 102 may not execute S201, that is, not Send the sixth message without reporting whether it supports the switching mechanism of the wake-up information detection scheme and the scheduling information detection scheme. The network device 100 has not received the sixth information reported by the terminal device 102. It may be assumed that the terminal device 102 does not support the switching mechanism of the wake-up information detection scheme and the scheduling information detection scheme.

S202. The base station sends fourth information, where the fourth information is used to indicate that the terminal device needs to receive the first information. Accordingly, the terminal device can receive the fourth information. The first information is used to indicate that the terminal device needs to receive wake-up information in a connected state, and the wake-up information is used to indicate whether the terminal device needs to receive scheduling information.

The fourth information is used to indicate that the terminal device needs to receive the first information, which may be understood as: the fourth information is used to indicate that the switching mechanism of the wake-up information detection scheme and the scheduling information detection scheme is turned on or off. For example, when the fourth information indicates that the terminal device needs to receive the first information, it can be understood that the network device enables a switching mechanism of the wake-up information detection scheme and the scheduling information detection scheme; when the fourth information indicates that the terminal device does not need to receive the first information, It can be understood that the network device switches off the switching mechanism between the wake-up information detection scheme and the scheduling information detection scheme; or when the network device does not send the fourth message, it can be understood that the network device does not enable the switching mechanism of the wake-up information detection scheme and the scheduling information detection scheme.

For example, the base station determines whether to switch the wake-up information detection scheme and the scheduling information detection scheme according to the sixth information sent by the terminal device, and sends the fourth information to the terminal device, instructing to enable or disable the wake-up information detection scheme and the scheduling information detection scheme. Switching mechanism.

The base station may instruct the terminal device to enable or disable this switching mechanism through signaling. The signaling may be RRC signaling, or MAC-CE signaling, or DCI signaling.

For example, the radio resource control setup (RRCSetup) signaling sent by the base station may include 1-bit switch indication information. When the switch indication information is True, it means that this mechanism is turned on, which means that the terminal device can subsequently switch according to the indication of the first information. Wake-up information detection scheme and scheduling information detection scheme; when the switch indication information is False, this mechanism is turned off, which means that the terminal device will only detect scheduling information in the future, but will not detect wake-up information.

Optionally, the base station may instruct all terminal devices in the cell to enable or disable the switching mechanism through broadcast signaling.

Optionally, in S202, the base station may send fifth information, where the fifth information is used to indicate whether the first information is valid. Accordingly, the terminal device can receive the fifth information. The first information is used to indicate whether the terminal device needs to receive wake-up information in a connected state, and the wake-up information is used to indicate whether the terminal device needs to receive scheduling information.

The fifth information is used to indicate whether the first information is valid. It can be understood that the fifth information is used to indicate whether to switch the wake-up information detection scheme and the scheduling information detection scheme switching mechanism.

For example, the base station determines whether to switch the wake-up information detection scheme and the scheduling information detection scheme switching mechanism according to the sixth information sent by the terminal device, and sends the fifth information to the terminal device, indicating that the first information is valid or invalid.

The base station may indicate whether the first information is valid through signaling. The signaling may be RRC signaling, or MAC-CE signaling, or DCI signaling.

For example, the RRCSetup signaling sent by the base station may include 1-bit switch indication information. When the switch indication information is True, the first information is valid. This means that the terminal device can subsequently switch the wake-up information detection scheme and Scheduling information detection scheme; when the switch indication information is False, the first information is invalid, which means that the terminal device will only detect the scheduling information in the future, but not the wake-up information.

As another example, the switch indication information may also be reflected as whether the signaling is configured, and the base station is configured with WUS configuration information, which indicates that the terminal device may subsequently switch the wake-up information detection scheme and the scheduling information detection scheme according to the indication of the first information. The base station does not have Configuring the WUS configuration information indicates that the terminal device will only detect scheduling information in the future, and will not detect wake-up information.

It should be understood that S202 is an optional step. In other words, in the communication method in the embodiment of the present application, S202 may not be performed. In this case, the terminal device may enable the above handover mechanism by default in the base station, that is, the terminal device may receive the first information by default in the connected state, and perform information detection according to the first information.

S203. The base station sends third information, where the third information is used to indicate a second time interval. Accordingly, the terminal device can receive the third information.

The second time interval can be understood as the interval between the time when the base station sends the wake-up information and the time when the scheduling information is sent, or it can be understood as the interval between the time when the terminal device receives the wake-up information and the time when the scheduling information is detected.

For example, if the terminal device receives a WUS and the WUS indicates that DCI will be sent in the future, the terminal device may not detect WUS in the future but directly detect DCI. The time interval between the WUS and the terminal device detecting the subsequent first DCI is the second time interval.

It should be understood that, in the embodiments of the present application, the time domain unit may be a subframe or a time slot, or may be other time domain units in other network architectures in the future. The second time interval will be described below with the time domain unit being a subframe as an example.

For example, if the terminal device detects WUS in the m-th subframe, and the WUS indicates that the terminal device will send DCI in the future, then the terminal device can detect the DCI in the "m + second time interval" subframe.

For example, as shown in FIG. 3, the second time interval is 2, and the unit is a subframe. If the terminal device detects a WUS in the m-th subframe, and the WUS indicates that there is a subsequent DCI, the terminal device may be at the m + 2 DCI is detected for each subframe.

Further, if a certain field in the DCI indicates that the base station has subsequent downlink data transmission (here, it is assumed that the first information is a certain field in the DCI), then the terminal device can detect the DCI in each subsequent subframe, Until this field in the DCI indicates that the base station does not send any more downlink data in the future.

It should be understood that S203 is an optional step. In other words, in the communication method in the embodiment of the present application, S203 may not be performed. For example, the second time interval may be a fixed value. For example, the second time interval may be a fixed value agreed in advance by the communication system or prescribed by the communication protocol. In this case, S203 may not be performed, that is, the base station does not need to notify the terminal device of the second time interval.

S204. The base station sends second information, where the second information is used to indicate a first time interval. Accordingly, the terminal device receives the second information.

The first time interval may be understood as the interval between the time when the base station sends the first information and the time when the wake-up information is sent, or the interval between the time when the terminal device receives the first information and the time when the wake-up information is detected, where: The first information is used to instruct the terminal device to receive wake-up information.

For example, the first information indicates that when the base station has no subsequent data to be sent, the terminal device will detect WUS. The time interval between the first WUS to be detected by the terminal device and this first information is the first time interval.

It should be understood that, in the embodiments of the present application, the time domain unit may be a subframe or a time slot, or may be other time domain units in other network architectures in the future. The first time interval will be described below with the time domain unit being a subframe as an example.

For example, if the terminal device detects the first information in the m-th subframe, and the first information indicates that the terminal device needs to detect WUS in the future, the terminal device detects WUS in the "m + first time interval" subframe.

For example, as shown in FIG. 4, the first time interval is 1 and the unit is a subframe. If the terminal device detects the first information in the m-th subframe and the first information indicates that there is no subsequent data transmission, the terminal device can WUS is detected at the m + 1th subframe.

Further, if CycleWUS = 2, the terminal device will detect subsequent WUS on m + 3, m + 5, ..., subframe. Among them, "CycleWUS" indicates the detection cycle of WUS. CycleWUS = 2 means that the UE detects WUS every 2 subframes.

The WUS detection period can be configured by the base station, or it can be a fixed value agreed by the communication system, or it can be a fixed value agreed by the communication protocol. For example, CycleWUS = 2 means that the UE detects WUS every 2 subframes.

The configuration manner of the detection period of the WUS may be the same as or similar to the configuration manner of the detection period of the WUS in the idle state. In this case, for a configuration manner of the WUS detection period, refer to a configuration manner of the WUS detection period in an idle state, and details are not described herein again. The terminal device receives the WUS configuration information in the connected state, receives WUS according to the WUS configuration information in the connected state, and no longer receives WUS according to the WUS configured in the idle state. This means that the WUS configuration information in the connected state overwrites the WUS configuration information in the idle state.

S205: The base station sends the first information. Accordingly, the terminal device receives the first information. The first information is used to indicate whether the terminal device needs to receive wake-up information in a connected state.

By way of example and not limitation, the first information may be carried in a DCI, a MAC-CE or RRC.

As a possible implementation manner of the embodiment of the present application, the first information may be carried in DCI. For example, the first information may be carried in the downlink DCI.

For example, the downlink DCI (downlink scheduling information indicating how the downlink data of the terminal device is transmitted) carries a field indicating whether the base station has subsequent data transmission, and this field is the first information. This field can be 1-bit indication information. For example, when this field is "0", it means that the base station has not sent any downstream data, and the terminal device can detect WUS in the future; when this field is "1", it means that the base station still has downlink data to be transmitted, and the terminal device needs to detect DCI in the future.

Alternatively, this field may be a resource scheduling field. If the bandwidth length of the resource indicated by this field is greater than 0, it means that the base station still has downlink data to send, and the terminal device can detect DCI. If the bandwidth length of the resource indicated by this field is equal to 0, it means that the base station has no subsequent downlink data to send, the terminal device can Detect WUS.

Optionally, the first information may be carried on the uplink DCI.

For example, the uplink DCI (uplink scheduling information indicating how the uplink data of the UE is sent) carries a field indicating whether the terminal device subsequently sends data, and this field is the first information. This field can be a resource scheduling field. When the bandwidth length of the resource indicated by this field is greater than 0, it indicates that the base station has allocated uplink scheduling resources to the terminal, and the terminal device can detect DCI. When the bandwidth length of the resource indicated by this field is equal to 0, it indicates that the base station The terminal device can detect WUS without allocating uplink scheduling resources to the terminal device.

As a possible implementation manner of the embodiment of the present application, the first information may be carried on the MAC-CE.

For example, a certain field in the MAC-CE signaling may be used as the first information. The terminal device determines whether to detect WUS or DCI in the future based on this field.

For example, the field carried in the MAC-CE indicates how much data the base station has to send in the future, that is, the field may be a buffer state report (BSR). When the downlink BSR in the MAC-CE indicates that the amount of data to be sent is greater than 0, the terminal device can detect DCI, and when the downlink BSR in the MAC-CE indicates that the amount of data to be sent is equal to 0, the terminal device can detect WUS.

As a possible implementation manner of the embodiment of the present application, the first information may be carried in RRC.

S206. The base station sends information according to the first information. Accordingly, the terminal device performs information detection according to the first information.

For example, if the first information is used to instruct the base station to send WUS in the connected state, the base station sends WUS; if the first information is used to instruct the base station to send DCI in the connected state, the base station sends DCI.

The base station sends information according to the first information, which can be understood as: the base station switches between the WUS detection scheme and the DCI detection scheme according to the first information. Correspondingly, the terminal device performs information detection according to the first information, which can be understood as: the terminal device switches between the WUS detection scheme and the DCI detection scheme according to the first information.

FIG. 5 is an example of switching between a WUS detection scheme and a DCI detection scheme.

In a possible implementation manner of the embodiment of the present application, the base station may configure a timer for the terminal device. When the terminal device does not detect DCI for NnoDCI times, the terminal device starts a timer and starts counting. The NnoDCI can be configured by the base station, or it can be a fixed value.

During the timer counting process, if the terminal device has not detected DCI, the terminal device starts to detect WUS when the timer expires. If the terminal device detects the DCI during the timer timing, the timer stops timing, resets the timing duration, and restarts timing.

For example, as shown in FIG. 5, the timer configured by the base station for the terminal device has a duration of 3 subframes and NnoDCI = 2. The terminal device detects DCI in the m-th subframe. No DCI is detected, and no DCI is detected for 2 subframes, that is, no DCI is detected on the m + 1th subframe and the m + 2th subframe, then the terminal device can be on the m + 2th subframe Turn on the timer to start counting. If the terminal device has not detected DCI until the m + 5th subframe, the terminal device detects WUS in the m + 6th subframe. If the terminal device detects DCI before the m + 5th subframe, for example, the terminal device detects DCI at the m + 4th subframe, the timer stops counting and resets the timing to 3 subframes and the +4 subframes restarted.
