Description

Communication method and communication device

Technical Field

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

Background

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

There is a dedicated signaling between the terminal device and the network device in the connected state, and the network device may send scheduling information and downlink data to the terminal device through a dedicated signaling, such as a Radio Resource Control (RRC) signaling, a media access control-control element (MAC-CE) signaling, or a Downlink Control Information (DCI) signaling. The terminal device may continuously monitor DCI sent by the network device in a connected state, where the DCI indicates how downlink resources are scheduled, or when the terminal device is to send uplink data, the DCI indicates which resources to send the uplink data. After detecting the DCI, the terminal device receives data or transmits data on the corresponding resource according to the indication of the DCI. Generally speaking, the terminal device does not know that the network device has not transmitted DCI, and can only attempt to receive DCI in every subframe, which results in power consumption of the terminal device due to detection of DCI in subframes where the network device has not transmitted DCI, but does not detect any valid DCI information.

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

The network device or the terminal device in fig. 1 may be hardware, or may be functionally divided software, or a combination of the two. The network devices or terminal devices in fig. 1 may communicate with each other through other devices or network elements.

In the communication system 100 shown in fig. 1, a network device 110 and terminal devices 101 to 106 constitute one communication system 100. In the communication system 100, the network device 110 may transmit downlink data to the terminal devices 101 to 106, and of course, the terminal devices 101 to 106 may transmit uplink data to the network device 110. It should be understood that terminal devices 101-106 may be, for example, cellular phones, smart phones, laptops, handheld communication devices, handheld computing devices, satellite radios, global positioning systems, PDAs, and/or any other suitable device for communicating over wireless communication system 100.

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 network.

The terminal devices 104 to 106 may form a communication system. In the communication system, the terminal device 105 may transmit downlink data to the terminal device 104 or the terminal device 106.

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

In addition, the terminal device may also have an INACTIVE (INACTIVE) state, where the terminal device in the INACTIVE state stops the connection between the terminal device and the network device, and when the terminal device needs to send data or the network side needs the terminal device to receive data, the terminal device requests the network device to resume the connection. The terminal device can send or receive data in the inactive state.

When no service data needs to be sent or received, the terminal device can enter an idle state to reduce power consumption. The terminal device in an idle state and the network side are not connected, when the network device needs to send service data to the terminal device or the network device needs to report the service data to the terminal device, the network device may notify the terminal device in a paging manner, that is, a paging message (paging) indicates that the terminal device has a data sending or receiving requirement, where the paging message means that the network device is looking for the terminal device, for example, when the network device has downlink data to send.

Accordingly, the terminal device may also listen to the paging message on a specific time-frequency resource. The specific time-frequency resource for the terminal device to listen to the paging message is generally called Paging Occasion (PO). If the terminal device monitors Downlink Control Information (DCI) scrambled by a paging radio network temporary identifier (P-RNTI) on the PO, the terminal device receives a paging message on a resource indicated by the P-RNTI DCI, and a terminal device identifier list is carried in a general paging message. If the terminal device finds its identity in the list, the terminal device will then initiate random access, attempting to access the network.

After receiving the paging message, the terminal device may enter a connected state under the instruction of the paging message, so as to send or receive service data.

The terminal device in the connected state is a state in which a connection has been established with the network device. There is a dedicated signaling between the connected terminal device and the network device, and the network device may send scheduling information and downlink data to the terminal device through a dedicated signaling, such as a Radio Resource Control (RRC) signaling, a medium access control-element (MAC-CE) signaling, or a DCI signaling. The terminal device may continuously monitor DCI sent by the network device in a connected state, where the DCI indicates how downlink resources are scheduled, or when the terminal device is to send uplink data, the DCI indicates which resources to send the uplink data. After detecting the DCI, the terminal device receives data or transmits data on the corresponding resource according to the indication of the DCI. Generally, the terminal device will detect DCI in the control region of each subframe, and the following situations may occur: the network device does not really transmit the DCI, but the terminal device does not know that the network device does not transmit the DCI, and the terminal device can only try to receive the DCI in each subframe, so that the terminal device consumes power for detecting the DCI in the subframe in which the network device does not transmit the DCI, but cannot detect any effective DCI information.

As a possible implementation, a WUS mechanism may be introduced for the terminal device in an idle state. The WUS is a sequence, and when detecting the sequence, the terminal device has low requirements on the receiver, because the terminal device does not need to turn on the baseband receiving module when detecting the sequence, and only needs to turn on part of circuits in the receiver. In the WUS mechanism, the purpose of WUS is to explicitly inform the terminal device whether the subsequent DCI scrambled by the P-RNTI is sent to the terminal device, namely, the terminal device can be awakened when the DCI scrambled by the P-RNTI exists. For example, if the terminal device detects the WUS, it indicates that the DCI scrambled by the P-RNTI will be sent subsequently, and then the terminal device detects the DCI scrambled by the P-RNTI on the subsequent PO; if the terminal device does not detect the WUS, the DCI which is not scrambled by the P-RNTI is not transmitted subsequently, and then the terminal device does not detect the DCI on the subsequent PO. In this mechanism, compared with the case that the terminal device directly detects the P-RNTI scrambled DCI on the PO, the terminal device detects the WUS more power-saving, that is, the WUS saves power consumption caused by the behavior of the terminal device to detect the DCI on the subsequent PO, so this mechanism can save power consumption of the terminal device in an idle state.

As a possible implementation, a WUS mechanism may be introduced for the connected terminal device. This means that the connected terminal device may receive the WUS signal first, and through the reception of the WUS, the terminal device determines whether DCI is to be transmitted subsequently. For example, if the WUS indicates that DCI is not to be transmitted subsequently, the terminal device does not receive DCI subsequently, and thus, the terminal device can save power consumption for detecting DCI.

However, since the connected terminal device generally receives and transmits data, it may be considered that the DCI sent by the connected network device is not in a sparse state, and especially when there is a downlink large packet data to be transmitted, the downlink DCI may be transmitted very densely and continuously. In this case, the terminal device detects the WUS before detecting the DCI each time, and instead consumes more power.

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

The present application proposes a new communication method for the above problem, which can be summarized as follows: and the terminal equipment judges whether the terminal equipment detects the awakening information or the scheduling information according to the indication information. This is a switching mechanism of the wake-up information detection scheme and the scheduling information detection scheme. Whether to switch is determined according to the indication of the indication information.

The awakening information detection scheme is as follows: before detecting the scheduling information, the terminal equipment detects the awakening information, and judges whether the terminal equipment needs to detect subsequent scheduling information according to the detection condition of the awakening information; the scheduling information detection scheme is as follows: the terminal equipment directly detects the scheduling information without detecting the awakening information in advance.

In the embodiment of the present application, the wake-up information is not limited to the wake-up function disclosed by the name, and may also have a function of enabling the terminal to sleep. For example, the detection and non-detection of the wake-up information are two-fold meanings, which respectively represent that the wake-up terminal detects subsequent scheduling information and indicate that the terminal device does not need to detect subsequent scheduling information; alternatively, the mask detected from the wakeup information may be mask 1 and mask 2, or may have a binomial meaning; or, according to the information carried by the wake-up information, indicating the meaning of binomial, etc.

One example of wake up information in this application is WUS. The WUS may be a ZC sequence, but the WUS is not limited to be a sequence. It may also be a signal, a pilot, a signaling, etc. When the wake-up information is a WUS, the implementation manner of the wake-up information may refer to the WUS in an idle state, which is not described herein again.

In the embodiment of the application, a connected state is used as a scene of a description scheme, but the technical scheme of the application is not limited to be only applicable to the connected state, and the technical scheme of the application can also be applicable to an inactive state.

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

An example of the communication method according to an embodiment of the present application is described below with wake-up information as a WUS, scheduling information as DCI, and a network device as a base station as an example.

Fig. 2 is a schematic flow chart of a communication method according to an embodiment of the present application. It should be understood that fig. 2 shows steps or operations of a communication method, but these steps or operations are only examples, and other operations or variations of the operations in fig. 2 may be performed by the embodiments of the present application, or not all the steps need to be performed, or the steps may be performed in other orders.

S201, the terminal device sends sixth information, wherein the sixth information is used for indicating whether the terminal device can receive the awakening information in the connection state. Accordingly, the base station receives the sixth information.

Wherein, the sixth information can be understood as: and a switching mechanism for indicating whether the terminal equipment supports the wake-up information detection scheme and the scheduling information detection scheme.

For example, if the terminal device supports a 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 switching mechanism of the wakeup information detection scheme and the scheduling information detection scheme, the sixth information is used for indicating that the terminal device cannot receive the wakeup information in the connected state.

In some possible implementations, the sixth information may be indicated by 1bit (bit). For example, the sixth information may be True, and in this case, the terminal device may be indicated to be capable of receiving the wake-up information in the connected state, that is, the terminal device supports a switching mechanism of the wake-up information detection scheme and the scheduling information detection scheme. True here may be denoted by "1".

Similarly, the sixth information may be False, and in this case, 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 may be represented by "0".

As an example and not by way of 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 complete (RRCConnectionComplete) signaling of the terminal device.

Or, the sixth information may be carried in Non-access stratum (NAS) signaling and sent to the core network, and then the core network notifies the network device.

It should be understood that S201 is an optional step. In other words, in the communication method according to the embodiment of the present application, not all terminal devices need to execute S201. That is, some or all terminal devices may not report the switching mechanism of whether the terminal devices support the wakeup information detection scheme and the scheduling information detection scheme. For a terminal device that does not report a handover mechanism whether the terminal device supports the wake-up information detection scheme or the scheduling information detection scheme, optionally, the base station may default that the terminal device supports or does not support the handover 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 a switching mechanism of the wakeup information detection scheme and the scheduling information detection scheme; the terminal device 102 may not execute S201, that is, does not send the sixth information, and does not report whether it supports the switching mechanism of the wakeup information detection scheme and the scheduling information detection scheme. The network device 100 does not receive the sixth information reported by the terminal device 102, and may default that the terminal device 102 does not support the switching mechanism of the wakeup information detection scheme and the scheduling information detection scheme.

S202, the base station sends fourth information, and the fourth information is used for indicating that the terminal equipment needs to receive the first information. Accordingly, the terminal device may receive the fourth information. The first information is used for indicating that the terminal equipment needs to receive the awakening information in a connected state, and the awakening information is used for indicating whether the terminal equipment needs to receive the scheduling information.

The fourth information is used for indicating that the terminal device needs to receive the first information, and may be understood as: the fourth information is used for indicating to turn on or turn off a switching mechanism of the wake-up information detection scheme and the scheduling information detection scheme. For example, when the fourth information indicates that the terminal device needs to receive the first information, it may be understood that the network device starts 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, the fourth information can be understood as a switching mechanism for the network device to close the wakeup information detection scheme and the scheduling information detection scheme; or when the network device does not send the fourth information, it may be understood that the network device does not start a switching mechanism of the wake-up information detection scheme and the scheduling information detection scheme.

For example, the base station determines to turn on or off the switching mechanism of the wake-up information detection scheme and the scheduling information detection scheme according to sixth information sent by the terminal device, and sends fourth information to the terminal device to indicate to turn on or off the switching mechanism of the wake-up information detection scheme and the scheduling information detection scheme.

The base station may instruct the terminal device to turn this handover mechanism on or off by signaling, which may be RRC signaling, or MAC-CE signaling, or DCI signaling.

For example, a radio resource control setup (RRCSetup) signaling sent by the base station may include 1-bit switch indication information, and when the switch indication information is True, it represents that the mechanism is turned on, which means 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; when the switch indication information is False, this means that the mechanism is turned off, which means that the terminal device will only detect the scheduling information and not the wake-up information.

Alternatively, the base station may instruct all terminal devices in the cell to turn on or off the handover mechanism through broadcast signaling.

Optionally, in S202, the base station may transmit fifth information, where the fifth information is used to indicate whether the first information is valid. Accordingly, the terminal device may receive the fifth information. The first information is used for indicating whether the terminal equipment needs to receive the awakening information in a connected state, and the awakening information is used for indicating whether the terminal equipment needs to receive the scheduling information.

The fifth information is used to indicate whether the first information is valid, and can be understood as: the fifth information is used for indicating to turn on or turn off a switching mechanism of the wake-up information detection scheme and the scheduling information detection scheme.

For example, the base station determines to turn on or off a switching mechanism of the wake-up information detection scheme and the scheduling information detection scheme according to sixth information sent by the terminal device, and sends fifth information to the terminal device to indicate whether the first information is valid or invalid.

The base station may indicate whether the first information is valid through signaling, which 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, and when the switch indication information is True, the switch indication information represents that the first information is valid, which means that the terminal device may switch the wake-up information detection scheme and the scheduling information detection scheme according to the indication of the first information; when the switch indication information is False, the first information is invalid, which means that the terminal device will only detect the scheduling information and will not detect the wake-up information.

For another example, the switch indication information may also be embodied as whether signaling is configured, and if the base station configures WUS configuration information, it indicates that the terminal device may switch the wakeup information detection scheme and the scheduling information detection scheme according to the indication of the first information, and if the base station does not configure WUS configuration information, it indicates that the terminal device will only detect scheduling information and will not detect wakeup information subsequently.

It should be appreciated that S202 is an optional step. In other words, in the communication method according to the embodiment of the present application, S202 may not be executed. In this case, the terminal device may default that the base station starts the handover mechanism, that is, the terminal device may default that the first information needs to be received 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 may receive the third information.

The second time interval may be understood as an interval from a time when the base station transmits the wake-up information to a time when the scheduling information is transmitted, or may be understood as an interval from a time when the terminal device receives the wake-up information to a time when the scheduling information is detected.

For example, if the terminal device receives a WUS and the WUS indicates that DCI will be transmitted subsequently, the terminal device may subsequently detect DCI directly without detecting the WUS. And the time interval between the WUS and the detection of the first subsequent DCI by the terminal equipment is the second time interval.

It should be understood that, in the embodiment of the present application, the time domain unit may be one subframe or one slot, and may also be other time domain units in other network architectures in the future. The second time interval will be described below by taking the time domain unit as a subframe as an example.

For example, if the terminal device detects a WUS in the mth subframe and the WUS indicates that the terminal device has DCI to transmit subsequently, then the terminal device may detect DCI in the "m + second time interval" subframe.

For example, as shown in fig. 3, the second time interval is 2 in subframes, and if the terminal device detects a WUS in the mth subframe and the WUS indicates that DCI follows, the terminal device may detect DCI in the m +2 th subframe.

Further, if a field in the DCI indicates that the base station subsequently transmits downlink data (assuming that the first information is a field in the DCI), the terminal device may detect the DCI in each subsequent subframe until the field in the DCI indicates that the base station subsequently does not transmit downlink data any more.

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

S204, the base station sends second information, and the second information is used for indicating the first time interval. Accordingly, the terminal device receives the second information.

The first time interval may be understood as an interval between a time when the base station transmits the first information and a time when the base station transmits the wakeup information, or may be understood as an interval between a time when the terminal device receives the first information and a time when the terminal device detects the wakeup information, where the first information is used to instruct the terminal device to receive the wakeup information.

For example, the first information indicates that the terminal device will detect WUS when the base station subsequently has no data to transmit. 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 embodiment of the present application, the time domain unit may be one subframe or one slot, and may also be other time domain units in other network architectures in the future. The first time interval will be described below by taking the subframe as an example of the time domain unit.

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

For example, as shown in fig. 4, if the first time interval is 1 and the unit is a subframe, if the terminal device detects the first information in the mth subframe, and the first information indicates that no data is transmitted subsequently, the terminal device may detect WUS in the (m + 1) th subframe.

Further, if CycleWUS is 2, the terminal device will detect subsequent WUS on m +3, m +5, …, subframes. Wherein "CycleWUS" indicates a detection period of WUS. A CycleWUS of 2 means that the UE detects WUS every 2 subframes.

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

The detection period of the WUS may be configured in the same or similar manner as the detection period of the WUS in the idle state. In this case, the configuration of the detection period of the WUS may refer to the configuration of the detection period of the WUS in the idle state, and details thereof are not repeated here. The terminal equipment receives the configuration information of the WUS in the connection state, receives the WUS according to the configuration information of the WUS in the connection state, and does not receive the WUS according to the WUS configured in the idle state any more. This means that the configuration information for the connected WUS overrides 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 for indicating whether the terminal equipment needs to receive the awakening information in the connected state.

By way of example and not limitation, the first information may be carried in DCI, media access layer control element 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 downlink DCI.

For example, downlink DCI (downlink scheduling information indicating how downlink data of the terminal device is to be transmitted) carries a field indicating whether the base station has data to transmit subsequently, where the field is the first information. This field may be 1bit indication information. For example, when the field is a bit "0", it indicates that the base station has no downlink data to transmit subsequently, and the terminal device may detect WUS subsequently; when the field is bit "1", it indicates that the base station still has downlink data to transmit subsequently, and the terminal equipment needs to detect DCI subsequently.

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

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

For example, the uplink DCI (uplink scheduling information indicating how uplink data of the UE is to be transmitted) carries a field indicating whether the terminal device has data to transmit subsequently, where the field is the first information. The field may be a resource scheduling field, and when the bandwidth length of the resource indicated by the field is greater than 0, it indicates that the base station has allocated the uplink scheduling resource to the terminal, and the terminal device may detect DCI; when the bandwidth length of the resource indicated by this field is equal to 0, it indicates that the base station has not allocated the uplink scheduling resource to the terminal device, and 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 the MAC-CE.

For example, a certain field in the MAC-CE signaling may be the first information. The terminal equipment judges whether to detect WUS or DCI subsequently according to the field.

For example, a field carried in the MAC-CE indicates how much data is to be sent by the base station subsequently, 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 transmitted is greater than 0, the terminal device may detect DCI, and when the downlink BSR in the MAC-CE indicates that the amount of data to be transmitted is equal to 0, the terminal device may detect WUS.

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

S206, the base station sends information according to the first information. Correspondingly, the terminal equipment carries out information detection according to the first information.

For example, if the first information is used to instruct the base station to transmit WUS in the connected state, the base station transmits WUS; and if the first information is used for indicating the base station to send the DCI in the connected state, the base station sends the 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. Accordingly, the terminal device performs information detection according to the first information, and 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 of 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 (Timer) for the terminal device. And when the terminal equipment does not detect the DCI for the consecutive NnDCI times, the terminal equipment starts a timer to start timing. Here, the nnocdci may be configured by the base station or may be a fixed value.

During the timing of the timer, if the terminal device does not detect the DCI, the terminal device starts detecting the WUS when the timer times out. If the terminal equipment detects the DCI in the timing process of the timer, the timer stops timing, resets the timing duration and restarts the timing.

For example, as shown in fig. 5, the timing duration of the timer configured by the base station for the terminal device is 3 subframes, and the nnocl is 2, the terminal device detects DCI in the mth subframe, and if the terminal device does not detect DCI in the (m + 1) th subframe and does not detect DCI for 2 subframes, that is, DCI is not detected in the (m + 1) th subframe and the (m + 2) th subframe, the terminal device may start the timer to start timing in the (m + 2) th subframe. If the terminal device has not detected DCI up to the m + 5th subframe, the terminal device detects WUS at the m +6 th subframe. If the terminal device detects the DCI before the m + 5th subframe, for example, the terminal device detects the DCI in the m +4 th subframe, the timer stops counting and resets the counting time for 3 subframes and restarts counting time on the m +4 th subframe.
