Description

Communication method and communication device

Technical Field

The present disclosure relates to the field of communications technologies, and in particular, to a communication method and a communication device.

Background

In order to reduce the power consumption of terminal devices, discontinuous reception (discontinuous reception, DRX) mechanisms have been introduced in wireless communications, such as long term evolution (long term evolution, LTE) systems. Under the DRX mechanism, the terminal device includes a sleep state (or referred to as sleep mode (sleep mode)) and an awake state (or referred to as awake mode (ON duration mode)) or referred to as drx_on state. In the sleep state, the terminal device may close communication devices such as a radio frequency transceiver and a baseband processor, and in the awake state, the terminal device needs to perform blind detection on a physical downlink control channel (physical downlink control channel, PDCCH), if downlink control information (downlink control information, DCI) sent by the network device is detected on the PDCCH, the terminal device receives downlink data on a time-frequency resource indicated by the DCI, and the like, and it is seen that under the DRX mechanism, the energy consumption overhead of the terminal device is mainly in the awake state. The terminal equipment can periodically enter the sleep state, so that the terminal equipment can achieve the purpose of saving electricity.

When the terminal equipment wakes up from the sleep state, the terminal equipment is in the wake-up state for a period of time, and the process still has the problem of high energy consumption. Therefore, if the energy consumption overhead is reduced, the terminal device can be provided with longer endurance.

Disclosure of Invention

The embodiment of the application provides a communication method and a communication device, which are used for improving the endurance of terminal equipment.

In a first aspect, a communication method is provided, in which a terminal device first detects whether a network device transmits a first signal for indicating whether the terminal device detects a control channel, the network device may agree in advance with the terminal device whether to instruct the terminal device to detect the control channel by transmitting the first signal, instruct the terminal device to detect the control channel when the network device transmits the first signal, or instruct the terminal device to detect the control channel by indicating content of the first signal, and when the terminal device determines that the control channel needs to be detected according to a detection result of the first signal (it may be understood that whether the first signal or the indication content of the first signal is detected), the first signal is further used for instructing the terminal device to perform measurement for a wideband or a partial frequency band, the terminal device may measure the wideband or the partial frequency band, and transmit the measurement result to the network device, where the wideband or the partial frequency band may be understood as an operating bandwidth of the terminal device or a part of an operating bandwidth of the terminal device.

In the above technical solution, the first signal may be used to instruct the terminal device whether to detect the control channel, and may also be used to instruct the terminal device to measure the wideband or the partial frequency band, so that when the terminal device determines that the control channel needs to be detected according to the detection result of the first signal, the terminal device may directly measure the wideband or the partial frequency band to obtain the state of the downlink channel of the terminal device. Since the first signal is typically detected before the terminal device enters the wake-up time, the terminal device may acquire the measurement before entering the wake-up time. Therefore, after the terminal equipment enters the wake-up time, the measurement result can be immediately sent to the network equipment, so that the network equipment can acquire the state of the downlink channel of the terminal equipment according to the measurement result, and timely adjust the scheduling strategy according to the state of the downlink channel of the terminal equipment, for example, when the state of the downlink channel of the terminal equipment is better, the data can be sent in a mode of using high rate and/or large code blocks as early as possible, the data transmission efficiency of the terminal equipment at the wake-up time can be improved, the terminal equipment can receive the data to the sleep state as early as possible, the duration of the terminal equipment in the wake-up state is reduced, and the energy consumption expense of the terminal equipment is reduced.

In one possible design, the network device sends first indication information for indicating a first resource set to the terminal device, at least one time-frequency resource in the first resource set is used for carrying the first signal, and second indication information for indicating a second resource set is sent to the terminal device by the network device, at least one time-frequency resource in the second resource set is used for the terminal device to measure a wideband or a partial frequency band, and the terminal receives the first indication information and the second indication information, where the time-frequency resources included in the first resource set and the second resource set are the same.

In the above technical solution, after the terminal device receives the first indication information and the second indication information, it is determined that the time-frequency resource used for carrying the first signal is the same as the time-frequency resource used for the terminal device to measure for the wideband or the partial frequency band, so that the terminal device may consider that on the time-frequency resource used for carrying the first signal, the terminal device may not only detect whether the first signal is on the time-frequency resource to determine whether to need to monitor the control channel, but also measure on the time-frequency resource for the wideband or the partial frequency band when the first signal is detected on the time-frequency resource, and thus, the utilization ratio of the time-frequency resource may be improved by multiplexing the time-frequency resource.

In one possible design, the identity of the first set of resources and the identity of the second set of resources are the same or different.

In the above technical solution, the terminal device may determine whether the time-frequency resource used for carrying the first signal is the same as the time-frequency resource used for the terminal device to measure the wideband or the partial frequency band by comparing whether the identifier of the first resource set is the same as the identifier of the second resource set, or may further determine whether the time-frequency resource indicated in the resource sets with different identifiers is the same when the identifier of the first resource set is different from the identifier of the second resource set, so as to improve flexibility of the terminal device.

In one possible design, the terminal device measures for a wideband or a partial band, it being understood that the terminal device measures the first signal. That is, the terminal device measures the wideband or the partial frequency band by measuring the first signal, so that the network device does not need to send a reference signal for measuring the wideband or the partial frequency band, the capacity of the downlink channel can be increased, and the signaling overhead between the network device and the terminal device can be reduced.

In one possible design, the second set of resources includes at least one first time-frequency resource, where a time domain position where each first time-frequency resource is located after a time domain position where the first signal is located and before a time domain position corresponding to an awake state where the terminal device enters the DRX, where the terminal device may detect, on the at least one first time-frequency resource, a reference signal for measurement of the wideband or the partial frequency band by measuring the reference signal, so as to implement measurement of the wideband or the partial frequency band.

In the above technical solution, before entering the DRX wake-up state, or before entering the start time of the wake-up time, the terminal device may measure the wideband or a part of the frequency band, so that after the terminal device enters the wake-up time, the terminal device may report the measurement result of measuring the wideband or the part of the frequency band without performing the step of measuring the wideband or the part of the frequency band, and may reduce the time delay of reporting the measurement result by the terminal device, so that the network device may acquire the channel state of the wideband or the part of the frequency band as soon as possible, thereby improving the data transmission efficiency and reducing the duration of the terminal device in the wake-up state.

In one possible design, the network device sends third indication information for indicating a third set of resources to the terminal device, where the third set of resources includes at least one time-frequency resource for carrying the measurement result. In this way, when the terminal device determines that the third resource set is in the third resource set according to the third indication information, the measurement result may be sent on the time-frequency resource in the third resource set.

In one possible design, after the terminal device enters the awake state of the DRX, the measurement result is sent in the uplink control channel through at least one time-frequency resource in the third set of resources, so that the network device receives the measurement result in the uplink control channel through at least one time-frequency resource in the third set of resources.

In the above technical solution, after the terminal device enters the DRX awake state, the measurement result may be directly reported in the time-frequency resource in the third resource set, which reduces the steps that the network device sends a reference signal for measuring the wideband or the partial frequency band to the terminal device and the terminal device measures the reference signal, so that the terminal device feeds back the measurement result to the network device faster than the prior art, and is convenient for the network device to acquire the channel state of the wideband or the partial frequency band as early as possible.

In one possible design, the network device first sends downlink control information DCI for indicating some or all of the time-frequency resources in the third resource set to send the measurement result, and after the terminal device enters an awake state of discontinuous reception DRX, the DCI is received, and then the terminal device sends the measurement result in an uplink shared channel through at least one of the time-frequency resources indicated by the DCI, so that the network device receives the measurement result in the uplink shared channel through at least one of the time-frequency resources indicated by the DCI.

In the above technical solution, the network device may only need to send DCI for indicating the terminal device to report the measurement result, so that the downlink channel state after the terminal device enters the DRX awake state may be known, and steps of the network device sending a reference signal for measuring CSI to the terminal device and the terminal device measuring the reference signal may be omitted, so that the measurement result may be reported to the network device more quickly.

In one possible design, after the terminal device enters the awake state of the discontinuous reception DRX, detecting, in a preset period of time, whether the network device transmits downlink control information DCI for indicating that part or all of the time-frequency resources in the third resource set are used to transmit the measurement result, when the terminal device detects the DCI in the preset period of time, transmitting the measurement result in an uplink shared channel through the time-frequency resources indicated by the DCI, and when the terminal device does not detect the DCI in the preset period of time, transmitting the measurement result in the uplink control channel through at least one time-frequency resource in the third resource set.

In the above technical solution, besides reporting the measurement result to the network device more quickly, the terminal device may also report the measurement result in multiple manners, so as to increase flexibility of the terminal device.

In one possible design, the terminal device may measure the channel state information CSI for the wideband or the partial band, in which case the measurement result is a measurement result of the terminal device for the wideband or the partial band, and/or the terminal device may measure the beam direction of the wideband or the partial band, in which case the measurement result is a measurement result of the terminal device for the beam direction of the wideband or the partial band.

In the above technical solution, the terminal device may measure CSI and/or beam direction, so that the network device may learn the channel state and/or the space state of the downlink channel earlier when the terminal device enters the initial stage of the DRX awake state, so as to use the transmission mode of the high rate and large code block earlier and/or use the narrow beam with larger throughput rate to transmit data to the terminal device earlier, reduce the duration of the terminal device in the awake state, and may reduce the energy consumption overhead of the terminal device.

For example, the network devices may include radio network controllers (radio network controller, RNC), node bs (Node bs, NB), base station controllers (base station controller, BSC), base transceiver stations (base transceiver station, BTS), home base stations (e.g., home evolved NodeB, or home Node bs, HNB), base Band Units (BBU), or wireless fidelity (wireless fidelity, wifi) Access Points (APs), etc., as well as evolved base stations (NodeB or eNB or e-NodeB, evolutional Node B) in long term evolution (long term evolution, LTE) systems or evolved LTE-Advanced, LTE-a systems, or next generation Node bs (next generation Node B, gNB) in fifth generation mobile communication technology (5G) new radio (new radio, NR) systems, in a network architecture, the network devices may include Concentrated Unit (CU) nodes, or distributed units (CU) nodes, and DUs. The embodiments of the present application are not limited.

In a network architecture, a base station includes a baseband device and a radio frequency device, where the baseband device may be implemented by one node, or may be implemented by multiple nodes, and the radio frequency device may be implemented independently from the baseband device, may be integrated into the baseband device, or may be partially integrated into the baseband device. For example, in an LTE communication system, a base station comprises a baseband device and a radio frequency device, wherein the radio frequency device may be remotely arranged relative to the baseband device, e.g. a remote radio unit (remote radio unit, RRU) is remotely arranged relative to the BBU.

The communication between the base station and the terminal device follows a certain protocol layer structure. For example, the control plane protocol layer structure may include the functions of protocol layers such as a radio resource control (radio resource control, RRC) layer, a packet data convergence layer protocol (packet data convergence protocol, PDCP) layer, a radio link control (radio link control, RLC) layer, a medium access control (media access control, MAC) layer, and a physical layer. The user plane protocol layer structure may include the functions of protocol layers such as PDCP layer, RLC layer, MAC layer, and physical layer; in one implementation, a traffic data adaptation (service data adaptation protocol, SDAP) layer may also be included above the PDCP layer.

The base station may implement, by one node, functions of protocol layers such as radio resource control (radio resource control, RRC), packet data convergence layer protocol (packet data convergence protocol, PDCP), radio link control (radio link control, RLC), and medium access control (Media Access Control, MAC); or the functions of the protocol layers may be implemented by a plurality of nodes; for example, in an evolution structure, a base station may include a Centralized Unit (CU) and a Distributed Unit (DU), and a plurality of DUs may be centrally controlled by one CU. The CU and the DU may be divided according to protocol layers of the wireless network, for example, functions of a PDCP layer and above are set at the CU, and functions of protocol layers below PDCP, for example, functions of an RLC layer and a MAC layer, etc. are set at the DU.

The division of the protocol layer is merely an example, and other protocol layers may be divided, for example, division in the RLC layer, where functions of the RLC layer and above are set in the CU, and functions of the protocol layer below the RLC layer are set in the DU; alternatively, the protocol layer may be divided, for example, by setting a part of functions of the RLC layer and functions of protocol layers above the RLC layer to CU, and setting the remaining functions of the RLC layer and functions of protocol layers below the RLC layer to DU. In addition, the functions that require processing time to meet the latency requirement may be set in the DU and the functions that do not require processing time to meet the latency requirement may be set in the CU in other manners, such as time-lapse partitioning.

In addition, the rf device may be remote, not placed in the DU, or may be integrated in the DU, or a portion of the remote may be integrated in the DU, without any limitation.

Alternatively, the Control Plane (CP) and the User Plane (UP) of the CU may be implemented separately and separated into different entities, i.e., a control plane CU entity (CU-CP entity) and a user plane CU entity (CU-UP entity), respectively.

In the above network architecture, the signaling generated by the CU may be transmitted to the terminal device through the DU, or the signaling generated by the terminal device may be transmitted to the CU through the DU. The DU may be passed through to the terminal device or CU directly through protocol layer encapsulation without parsing the signaling. In the following embodiments, transmission or reception of signaling by a DU includes such a scenario if such signaling is involved in the transmission between the DU and the terminal device. For example, the signaling of the RRC or PDCP layer is eventually processed as the signaling of the PHY layer to be transmitted to the terminal device, or is converted from the received signaling of the PHY layer. Under this architecture, the signaling of the RRC or PDCP layer can be considered as being sent by either a DU or by both a DU and a radio frequency.

In the above embodiments, the CU is divided into network devices on the Radio Access Network (RAN) side, and in addition, the CU may be divided into network devices on the Core Network (CN) side, which is not limited herein.

The apparatus in the following embodiments of the present application may be a terminal device or a network device according to the function implemented by the apparatus. When the above structure of CU-DUs is adopted, the network device may be a CU node, or a DU node, or a base station including a CU node and a DU node.

3) Time-frequency resources in a wireless communication system are typically described in units of physical resource blocks (physical resource block, PRBs) or RBs or Resource Elements (REs). One PRB includes 2 slots (slots) in the time domain, i.e., 14 orthogonal frequency division multiplexing multiple access (Orthogonal Frequency Division Multiple, OFDM) symbols, and 12 subcarriers in the frequency domain. One PRB includes 2 adjacent RBs, that is, one RB includes 12 subcarriers in the frequency domain and 1 slot in the time domain. One RE includes one OFDM symbol in the time domain and one subcarrier in the frequency domain. It should be noted that, in the embodiments of the present application, the terms "time-frequency resource" and "resource" may be used interchangeably.

4) The period of discontinuous reception (DRX cycle), one DRX cycle is equal to the sum of the wake-up time (ON-duration) and the sleep time of the terminal device, as shown in fig. 1. There are two kinds of DRX cycles, namely a DRX long cycle and a DRX short cycle, and the DRX long cycle is an integer multiple of the DRX short cycle. The network device can configure a DRX short period and a DRX long period for the terminal device, when the DRX short period is ended, the terminal device enters the DRX long period once, the network device can only configure the DRX long period for the terminal device and does not configure the DRX short period, and the configuration conditions of the DRX long period and the DRX short period are determined according to actual use requirements.

5) The control channels can be divided into an uplink control channel and a downlink control channel, wherein the uplink control channel can be a physical uplink control channel (physical uplink control channel, PUCCH), a machine type communication physical uplink control channel (MTC physical uplink control channel, MPUCCH), a narrowband physical uplink control channel (Narrowband physical uplink control channel, NPUCCH) or the like; the downlink control channel may be a physical downlink control channel (physical downlink control channel, PDCCH), or a machine type communication physical downlink control channel (MTC physical downlink control channel, MPDCCH), or a narrowband physical downlink control channel (Narrowband physical downlink control channel, NPDCCH), etc.

6) The uplink shared channel may be a physical uplink shared channel (physical uplink shared channel, PUSCH), a machine type communication physical uplink shared channel (MTC physical uplink shared channel, MPUSCH), or a narrowband physical uplink shared channel (Narrowband physical uplink shared channel, NPUSCH).

7) An inactivity timer (inactivity timer) for indicating the number of consecutive time units after the PDCCH indicates data transmission, or may be understood as indicating the time for the terminal device to detect a control channel after the control channel indicating data transmission, or may be understood as indicating the number of consecutive time units for the control channel after the terminal device detects a control channel indicating data transmission, or may be understood as indicating the time for the terminal device to detect a control channel after the terminal device detects Downlink Control Information (DCI) indicating data transmission. The terminal device listens to the PDCCH during this period. The time unit may be 1ms.

Note that, the inactive timer is a name used in the LTE system, and when the timer is applied to other communication systems, for example, an NR system or other types of communication systems, other names may be used, and in the embodiment of the present application, the name of the timer is not limited. This timer will be described below as an example of an inactive timer.

8) The terms "system" and "network" in embodiments of the present application may be used interchangeably. The term "plurality" means two or more, and in view of this, the term "plurality" may also be understood as "at least two" in the embodiments of the present application. "at least one" may be understood as one or more, for example as one, two or more. For example, including at least one means including one, two or more, and not limiting what is included, e.g., including at least one of A, B and C, then A, B, C, A and B, A and C, B and C, or A and B and C, may be included. "and/or", describes an association relationship of an association object, and indicates that there may be three relationships, for example, a and/or B, and may indicate: a exists alone, A and B exist together, and B exists alone. The character "/", unless otherwise specified, generally indicates that the associated object is an "or" relationship.

Unless stated to the contrary, the embodiments of the present application refer to ordinal terms such as "first," "second," etc., for distinguishing between multiple objects and not for defining a sequence, timing, priority, or importance of the multiple objects.

Having introduced some concepts to which embodiments of the present application relate above, features of embodiments of the present application are described below.

In an LTE system, the DRX mechanism includes the following features:

referring to fig. 2, in the active state of the connection state, the terminal device starts an inactivity timer, and monitors a physical downlink control channel (physical downlink control channel, PDCCH) in a period when the inactivity timer is started. Once the terminal device receives downlink control information (downlink control information, DCI) (or may be referred to as scheduling DCI) sent by the network device to the terminal device on the PDCCH, the terminal device restarts the inactive timer and then continues to monitor the PDCCH. If the terminal device does not receive the DCI sent to the terminal device on the PDCCH for a period of time, which results in an inactive timer timeout, in this case, the terminal device enters a sleep state of the DRX cycle. After the sleep time in the DRX cycle is over, the terminal equipment is awakened, enters an awakening state, then starts an inactive timer, and monitors the PDCCH in the period of time when the inactive timer is started. If the terminal device receives the DCI for data transmission sent by the network device to the terminal device on the PDCCH before the wake-up time of the DRX cycle is over, the terminal device restarts the active timer, continues to monitor the PDCCH, and receives data on the time-frequency resource indicated by the DCI. If the terminal equipment does not receive DCI (downlink control information) for data transmission sent to the terminal equipment in the wake-up time of the DRX cycle, the terminal equipment enters a sleep state again when the inactive timer is out of time. Because the communication devices such as the radio frequency transceiver, the baseband processor and the like can be completely closed when the terminal equipment is in the sleep state, the terminal equipment can save power consumption by periodically entering the sleep state.

In the LTE system, when the terminal device is in an awake state, the terminal device blindly checks on the PDCCH whether there is DCI for data transmission sent to the terminal device. In a next generation communication system, for example, a fifth generation mobile communication technology (5th generation mobile networks or 5th generation wireless systems,5G) or, alternatively, a New Radio (NR) system, a network device may configure a plurality of different types of PDCCHs for a terminal device, so that the network device may transmit different types of DCIs, for example, DCIs for configuring an operating band of the terminal device, or DCIs for configuring demodulation reference signals (demodulation reference signal, DMRS) of the terminal device, and so on, to the terminal device. In most cases, the network device may not send DCI for data transmission to the terminal device during the wake-up time of the DRX cycle, and thus in a next generation communication system, e.g. an NR system, an improved method for saving power consumption of the terminal device is provided, in which method a wake-up signal (WUS) is introduced, the method comprising the following features:

after the terminal device enters a connection state, the network device may send WUS configuration signaling to the terminal device, where the WUS configuration signaling includes a set of time-frequency resources for carrying WUS and/or an offset between a time when the network device sends the WUS and a starting time of a wake-up time of the terminal device in a DRX cycle, where the WUS is used to indicate whether the terminal device needs to detect a PDCCH in wake-up times (generally, a value of L is 1) of L continuous DRX cycles, so when the terminal device enters a sleep time of the DRX cycle, the terminal device may determine whether to wake up in the wake-up time of the DRX cycle according to the WUS.

As an example, the offset between the time when the WUS is sent by the network device and the starting time of the wake-up time of the DRX cycle by the terminal device is N slots in the WUS configuration signaling, as shown in fig. 3, the terminal device wakes up N slots before the starting time of the wake-up time of the DRX cycle, and detects WUS on the time-frequency resource indicated in the WUS configuration signaling. If the network device may send DCI for transmitting data to the terminal device in the consecutive L wake-up times (generally, the value of L is 1) after the WUS, the network device sends the WUS on the time-frequency resource indicated in the WUS configuration signaling, so when the terminal device detects the WUS, the terminal device may wake-up the blind-check PDCCH in the wake-up times of the consecutive L DRX cycles after the WUS; if the network device does not send DCI for transmitting data to the terminal device in the consecutive L wake-up times after the WUS, the network device does not send WUS, so that when the terminal device is not detected after being woken up in N time slots before the start time of the wake-up time of the DRX cycle, the terminal device may not need to wake up in the wake-up time of the consecutive L DRX cycles after the WUS, and further does not need to blindly detect the PDCCH, thereby reducing the number of times that the terminal device wakes up in the wake-up time of the DRX cycle, and further saving the power consumption of the terminal device.

In the above technical solution, although the power consumption of the terminal device may be reduced by reducing the number of times the terminal device wakes up at the wake-up time of the DRX cycle, when the terminal device determines that it needs to wake up at the wake-up time of the DRX cycle, and after entering the wake-up state, the terminal device will be in the wake-up state for a period of time. As an example, when the terminal device is in the awake state, the terminal device first starts an inactive timer and listens to the PDCCH during the period in which the inactive timer is started. If the terminal equipment receives DCI (downlink control channel) for data transmission sent by the network equipment to the terminal equipment on the PDCCH before the wake-up time of the DRX cycle is ended, the terminal equipment receives data sent by the network equipment on a time-frequency resource indicated by the DCI, and when the terminal equipment receives the data sent by the network equipment, the terminal equipment restarts an inactive timer and enters a sleep state again when the inactive timer is overtime.

From the above procedure, it can be seen that the duration of time that the terminal device is in the awake state is related to the data sent by the network device that the terminal device is receiving in the awake state.

In an NR system, in order to obtain the best air interface resource utilization efficiency, a network device matches the state of a downlink channel (for example, a physical downlink shared channel (physical downlink shared channel, PDSCH) or the like) when transmitting data, however, when a terminal device enters a wake-up state from a sleep state, the network device does not know the state of the downlink channel of the terminal device, so in order to ensure that the terminal device can receive the data, the network device generally adopts a conservative scheduling policy, that is, adopts a low-rate and small-code block mode to transmit the data, which will cause low data transmission efficiency at the wake-up time of the terminal device, thereby increasing the duration that the terminal device is in the wake-up state and further increasing the energy consumption expense of the terminal device, and therefore, how to reduce the energy consumption expense is a technical problem to be solved currently.

In view of this, an embodiment of the present application provides an information transmission method in which a terminal device first detects a first signal for indicating whether the terminal device detects a control channel, and then determines whether the terminal device needs to detect the control channel according to a detection result of the first signal. If the terminal device determines that the control channel needs to be detected, the terminal device needs to perform measurement for a wideband or a partial frequency band in addition to waking up to detect the control channel when the wake-up time of the discontinuous reception period arrives, and sends the measurement result to the network device.

In the above technical solution, after the terminal device determines that the control channel needs to be detected according to the detection result of the first signal, the terminal device may directly measure for a wideband or a partial frequency band to obtain the state of the downlink channel of the terminal device. Since the first signal is typically detected before the terminal device enters the wake-up time, the terminal device may acquire the measurement before entering the wake-up time. Therefore, after the terminal equipment enters the wake-up time, the measurement result can be immediately sent to the network equipment, so that the network equipment can acquire the state of the downlink channel of the terminal equipment according to the measurement result, and timely adjust the scheduling strategy according to the state of the downlink channel of the terminal equipment, for example, when the state of the downlink channel of the terminal equipment is better, the data can be sent in a mode of using high rate and/or large code blocks as early as possible, the data transmission efficiency of the terminal equipment at the wake-up time can be improved, the terminal equipment can receive the data to the sleep state as early as possible, the duration of the terminal equipment in the wake-up state is reduced, and the energy consumption expense of the terminal equipment is reduced.

The technical scheme provided by the embodiment of the application can be applied to an NR system, a long term evolution advanced (advanced long term evolution, LTE-A) system, a worldwide interoperability for microwave access (worldwide interoperability for microwave access, wiMAX) system, a wireless local area network (wireless local area networks, WLAN) system and the like.

In addition, the communication system may be further adapted to future-oriented communication technologies, and the system described in the embodiments of the present application is for more clearly describing the technical solutions of the embodiments of the present application, and does not constitute a limitation on the technical solutions provided in the embodiments of the present application, and as a person of ordinary skill in the art can know that, with the evolution of the network architecture, the technical solutions provided in the embodiments of the present application are also applicable to similar technical problems.

A network architecture to which the embodiments of the present application are applied is described below, with reference to fig. 4.

Fig. 4 includes a network device and a terminal device, and the terminal device is connected to one network device. Of course, the number of terminal devices in fig. 4 is merely an example, and in practical applications, the network device may serve multiple terminal devices. Further, in the network architecture shown in fig. 4, although the network device and the terminal device are shown, the network architecture may not be limited to include the network device and the terminal device. For example, core network devices or devices for carrying virtualized network functions, etc., which will be apparent to those of ordinary skill in the art, are also included and are not described in detail herein.

The network device in fig. 4 may be AN Access Network (AN) device, such as a base station. The access network device may correspond to different devices in different systems, for example, may correspond to an eNB in an LTE system, and may correspond to an access network device in NR in an NR system, for example, a gNB.

The following describes the technical scheme provided by the embodiment of the application with reference to the accompanying drawings.

An embodiment of the present application provides a communication method, please refer to fig. 5, which is a flowchart of the method.

In the following description, this method is applied to the network architecture shown in fig. 4 as an example, that is, the network device described below may be a network device in the network architecture shown in fig. 4, and the terminal device described below may be a terminal device in the network architecture shown in fig. 4. In addition, the method may be performed by two communication devices, for example a first communication device and a second communication device, wherein the first communication device may be a network device or a communication device capable of supporting the functions required by the network device to implement the method, but may also be other communication devices, such as a chip system. The same applies to the second communication device, which may be a terminal device or a communication device capable of supporting the functions required by the terminal device to implement the method, but may also be other communication devices, such as a chip system. And the implementation manner of the first communication apparatus and the second communication apparatus is not limited, for example, the first communication apparatus may be a network device, the second communication apparatus may be a terminal device, or the first communication apparatus may be a network device, the second communication apparatus may be a communication apparatus capable of supporting functions required by the terminal device to implement the method, and so on.

For ease of description, hereinafter, the method is performed by the network device and the terminal device, that is, the first communication apparatus is the network device and the second communication apparatus is the terminal device.

S501, the terminal equipment accesses the network equipment.

The terminal device first needs to access the network device before the terminal device communicates with the network device.

As an example, the terminal device may implement access by way of random access. For example, the terminal device performs downlink synchronization first, and obtains system information such as a system frame number and random access resource information from a physical broadcast channel (physical broadcast channel, PBCH), where in the random access resource information, a time density, a frequency, a sequence, and other resources that the terminal device can send random access are indicated, and then the terminal device generates a random access preamble (preamble) according to the random access resource information, and sends the random access preamble at a time and a frequency location indicated by the random access resource information. When the network device receives the random access preamble, it sends a random access response (random access response, RAR) to the terminal device, and when the terminal device receives the RAR, it interacts with the network device according to the information indicated in the RAR, thereby accessing the network device.

Of course, the terminal device may access the network device in other manners, which are not limiting herein.

S502, the network equipment sends DRX configuration information, and the terminal equipment receives the DRX configuration information.

In this embodiment of the present application, the DRX configuration information may include a DRX short cycle and/or a DRX long cycle configured by the network device for the terminal device, and a duration of a wake-up time and a duration of a sleep time in the DRX short cycle and/or the DRX long cycle, which may of course also include other configuration information, for example, an initial value of an activity timer is configured, which is not illustrated herein.

The DRX configuration information may be a configuration signaling dedicated to configuring DRX, for example, may be radio resource control (radio resource control, RRC) signaling, or may also be medium access control element (media access control control element, MAC CE) signaling, etc., and may also be included in other configuration messages, which may be RRC setup messages, RRC reestablishment messages, or RRC reconfiguration messages, etc., without limitation.

S503, the network equipment sends first indication information, and the terminal equipment receives the first indication information.

In this embodiment of the present application, the first indication information is used to indicate a first resource set, and at least one time-frequency resource in the first resource set is used to carry a first signal, where the first signal is described below.

The first signal is used to indicate whether the terminal device detects the control channel, taking the control channel as the PDCCH as an example, it can be understood that the first signal is used to indicate whether the terminal device detects the PDCCH. For the network device, the first signal is used to indicate whether the terminal device detects the control channel, which is to say, whether the network device transmits DCI, that is, if the network device transmits DCI, the terminal device detects the control channel, and if the network device does not transmit DCI, the terminal device does not need to detect the control channel.

The first signal may be a signal predetermined by the terminal device and the network device, for example, the first signal may be a null packet including only a specific packet header, or may be a signal carrying other specific contents, which is not limited herein. The first signal may also be referred to as a Wake Up Signal (WUS), which may be control signaling, carried on the PDCCH in the form of DCI, and which may be carried on the PDSCH in the form of a signal or pilot, e.g., which may be a constant envelope zero auto-correlation (CAZAC) sequence, such as a Zadoff-Chu (ZC) sequence, frank sequence, golomb polyphase sequence, or Chirp sequence, etc. In the embodiment of the present application, the specific form of the first signal is not limited.

In addition, the first signal may have two properties, that is, the first signal may be used to instruct the terminal device to detect the control channel, or may be used to instruct the terminal device not to detect the control channel. For example, the network device may indicate the two items by transmitting the first signal and not transmitting the first signal, the network device determines that DCI corresponding to the terminal device will be transmitted in the control channel, and then the network device transmits the first signal to the terminal device, and after receiving the first signal, the terminal device determines that DCI can be detected in a wake-up time after the first signal, thereby determining to detect the control channel; if the network device determines that the DCI corresponding to the terminal device is not transmitted in the control channel, the network device will not transmit the first signal, and if the terminal device does not detect the first signal, it determines that the DCI is not detected in a wake-up time after the first signal, thereby determining that the control channel is not detected.

Alternatively, the network device may indicate the bivariality according to the content carried by the first signal, that is, whether the network device will transmit DCI corresponding to the terminal device in the control channel or not, the network device will transmit the first signal, but the content carried in the first signal is different in different cases. For example, the network device indicates the bivariality through the mask of the first signal, and the network device and the terminal device pre-define that when the mask carried in the first signal is mask 1, the representative network device will send DCI corresponding to the terminal device in the control channel, and when the mask carried in the first signal is mask 2, the representative network device will not send DCI corresponding to the terminal device in the control channel. Therefore, after the terminal device receives the first signal, it can determine whether the network device will send DCI corresponding to the terminal device in the control channel according to the mask in the first signal, so as to determine whether to detect the control channel. Or, the network device may directly carry the information about whether to detect the control channel in the first signal, and after receiving the first signal, the terminal device determines whether to detect the control channel according to the information, that is, if the information indicated by the first signal is the detection control channel, the terminal device determines to detect the control channel, and if the information indicated by the first signal is the non-detection control channel, the terminal device determines to not detect the control channel. In the embodiment of the present application, the manner of bivariate indication of the first signal is not limited.

The specific form and the bivariate indication manner of the first signal may be pre-agreed by the network device and the terminal device, or the specific form and the bivariate indication manner of the first signal may be indicated to the terminal device by the network device, for example, the specific form and the bivariate indication manner of the first signal may be indicated to the terminal device through DRX configuration information in S502, or may be indicated to the terminal device through other information, for example, the specific form and the bivariate indication manner of the first signal may be indicated to the terminal device by sending DCI before S502, which is not limited herein. For convenience of explanation, hereinafter, a bivariate is exemplified by whether or not to transmit the first signal.

Next, the first resource set will be described.

The number of the first resource sets may be one or more, and for convenience of description, the number of the first resource sets will be taken as an example hereinafter. The first resource set may include one or more time-frequency resources, and any one Resource Element (RE) in the first resource set may be understood as any one resource element in the first resource set, where the resource element may be an RE, a combination of multiple REs, or the like, which is not described herein. Wherein the RE includes one orthogonal frequency division multiplexing (orthogonal frequency division multiplexing, OFDM) symbol in a time domain and one subcarrier in a frequency domain.

In the embodiment of the present application, the resources in the first resource set may be part or all of the resources occupied by a downlink channel estimation for a terminal device and a non-0 power channel state information reference signal (NZP CSI-RS) for channel measurement or beam measurement, or part or all of the resources occupied by a non-0 power or 0 power CSI-RS (ZP CSI-RS) for interference measurement, or part or all of the resources occupied by a common reference signal, or the like. For convenience of explanation, in the following description, the first resource set is taken as an example where the resource is an NZP CSI-RS resource.

Please refer to fig. 6, which is an example of the first resource set. In fig. 6, the first resource set includes 2 NZP CSI-RS resources, where one NZP CSI-RS resource represents a combination of multiple REs, that is, one NZP CSI-RS resource in the first resource set represents one NZP CSI-RS resource pattern, and each NZP CSI-RS resource pattern occupies one OFDM symbol in one slot in the time domain and occupies multiple subcarriers in the frequency domain. For example, the first resource set shown in fig. 6 includes 2 NZP CSI-RS resources, where the first NZP CSI-RS resource occupies the 3 rd OFDM symbol in one slot, and occupies the 3 rd subcarrier, the 7 th subcarrier, and the 11 th subcarrier in the frequency domain, that is, the password in the frequency domain is 3 RE/symbol; the second NZP CSI-RS resource occupies the 7 th OFDM symbol in one slot, and occupies the 3 rd subcarrier, the 7 th subcarrier, and the 11 th subcarrier on the frequency domain, respectively.

In the embodiment of the present application, the first indication information may include, but is not limited to, the following three indication manners:

the first indication mode is as follows:

and directly indicating a plurality of NZP CSI-RS resources corresponding to the first resource set in the first indication information. For example, a plurality of NZP CSI-RS resources corresponding to the first set of resources are indicated through RRC signaling.

As an example, the plurality of NZP CSI-RS resources may be configured by invoking a NZP-CSI-RS-Resource: =sequence { } message. The NZP-CSI-RS-Resource comprises at least the following parameters in the message of =SEQUENCE { }:

1. NZP-CSI-RS-resource id, which is used to indicate the identifier of the NZP CSI-RS resource;

2. the resource mapping is used for expressing how NZP CSI-RS resources are mapped to a time domain and a frequency domain;

3. powercontrol offset and powercontrol offsetss, both of which are transmission power control parameters for indicating transmission power used by the network device when transmitting the first signal on the NZP CSI-RS resource;

4. the scramblingID is used to instruct the network device to generate a scrambling code using a first signal sequence when transmitting the first signal on the NZP CSI-RS resource;

5. the method comprises the steps that a parameter is used for indicating network equipment to send periodic configuration information of a first signal on the NZP CSI-RS resource;

6. qcl-InfoPeriodacCSI-RS, which is used to instruct the network device to transmit beam information for the first signal on the NZP CSI-RS resource.

The second indication mode is as follows:

the first set of resources is indicated in the first indication information.

As an example, the first set of resources may be configured by invoking the NZP-CSI-RS-resource: =sequence { } message. The NZP-CSI-RS-resource: = SEQUENCE { } message may include, but is not limited to, the following parameters:

1. NZP-CSI-ResourceSetId, an identifier indicating the set of NZP CSI-RS resources. It can be understood that the network device divides the plurality of NZP CSI-RS resources into a plurality of NZP CSI-RS resource sets in advance, and indicates, by the NZP-CSI-ResourceSetId parameter, a resource set configured by the network device for the terminal device and used for transmitting the first signal;

2. NZP-CSI-RS-Resources for indicating how many NZP CSI-RS Resources are contained in the first set of Resources, and an identifier of each NZP CSI-RS resource;

3. repetition, which is used for indicating whether the NZP CSI-RS resource is repeatedly transmitted or not, and is mainly used in beam detection;

4. an apersidctriggeringoffset for indicating an offset between a transmission time of DCI transmitted by a first signal and a transmission time of the first signal when the first signal is transmitted by aperiodically occupying NZP CSI-RS resources in the first resource set;

5. trs-Info indicating whether the first signal is used for time-frequency offset estimation.

Third indication mode:

the first indication information may be dedicated configuration signaling for configuring the first signal. The dedicated configuration signaling may be implemented by invoking a Wakeup-signal-Resource: =sequence { } message. The Wakeup-signal-Resource: =sequence { } message may include, but is not limited to, the following parameters:

1. wakeup-signal-resource id, which is used to indicate an identifier of NZP-CSI-RS-resource set;

2. wakeup-offset, the parameter is used for indicating an offset between a sending time when the network device sends the first signal on the NZP CSI-RS resource and a starting time when the terminal device wakes up in a DRX period;

in a specific implementation process, a person skilled in the art may configure the indication manner of the first indication information according to the use requirement, which is not limited herein. It should be understood that the above three indication modes are merely illustrative of the first indication information, and should not be construed as limiting the indication modes of the first indication information.

S504, the network equipment sends second indication information, and the terminal equipment receives the second indication information.

In the embodiment of the present application, the second indication information is used to indicate a second set of resources, where at least one time-frequency resource in the second set of resources is used for the terminal device to measure for a wideband or a partial frequency band.

It will be appreciated that if the terminal device uses a reference signal, e.g., a channel state information reference signal (CSI-RS), to measure the wideband or partial frequency band, then each time-frequency resource in the second set of resources is used to carry the reference signal. Hereinafter, the measurement of a wideband or a partial band by a terminal device using CSI-RS will be described as an example.

It should be noted that, the terminal device measures for a wideband or a partial frequency band, which can be understood that if the working bandwidth of the terminal device is the carrier bandwidth of the whole communication system, for example, in the LTE system, the working bandwidth of the terminal device is the same as the carrier bandwidth of the LTE system, the terminal device measures for the wideband; if the operating bandwidth of the terminal device is a partial band of the carrier bandwidth, for example, the NR system supports that the terminal device operates on a partial Bandwidth (BWP) in the carrier bandwidth of the NR system, so that the terminal device only needs to measure for the partial bandwidth (or called the partial band).

For the description of the second resource set, please refer to the description of the first resource set in S503, which is not repeated here. Hereinafter, the NZP CSI-RS resource is taken as an example of the resources in the second resource set.

The indication manner of the second indication information may include, but is not limited to, the following three manners:

the first indication mode in the second indication information is similar to the first indication mode in the first indication information, and the second indication mode in the second indication information is similar to the second indication mode in the first indication information, and is not described herein.

Third indication mode:

the network device indicates the second set of resources by invoking a CSI-ReportConfig =sequence { } message. The CSI-ReportConfig: =sequence { } message includes, but is not limited to, the following parameters:

1. reportConfigId, which is used to indicate the identity of the reference signal configuration (resources for channel) parameter and the identity of the reporting configuration (reportConfig) parameter;

it should be noted that, the network device may configure a plurality of reference signal configuration parameters and a plurality of reporting configuration parameters for the terminal device in advance, where each reference signal configuration parameter corresponds to an identifier, and each reporting configuration parameter corresponds to an identifier, where the reference signal configuration parameters are used to instruct the terminal device to measure on which time-frequency resources to use for a wideband or a partial frequency band, for example, may instruct an NZP CSI-RS resource set, and the reporting configuration parameters are used to instruct content that should be included in a measurement result reported by the terminal device, for example, the measurement result may include measurement results of channel state information CSI such as reference signal received power (reference signal received power, RSRP), reference signal received quality (reference signal received quality, RSRQ), and the like.

2. carrier, the parameter is used for indicating the index number of the serving cell of the terminal equipment;

3. the resource esforchannelmeasurement parameter is used to indicate the resources used by the terminal device to measure for the wideband or the partial band. Wherein the set of NZP CSI-RS resources for measurement for wideband or partial frequency bands is indicated by a ResourceSetList in the parameter.

In this embodiment of the present application, the time-frequency resources included in the first set of resources in S503 are the same as the time-frequency resources included in the second set of resources in S504. Specifically, the time-frequency resources included in the first resource set and the time-frequency resources included in the second resource set may be implemented in two ways, including but not limited to:

in a first implementation manner, the identifier of the first resource set included in the first indication information is the same as the identifier of the second resource set included in the second indication information:

as an example, assume that the network device configures 10 NZP CSI-RS resource sets in advance for the terminal device, identifiers of the 10 NZP CSI-RS resource sets are 01 to 10, respectively, and the network device determines to use the NZP CSI-RS resource set 2 as the first resource set and the second resource set. The network device indicates the first resource set by adopting the second indication mode in S503, and when the network device sends the first indication information to the terminal device, the value of nzp-CSI-resource id parameter in the first indication information may be set to be 02; and the network equipment adopts the second indication mode in the S504 to indicate the second resource set, and when the network equipment sends second indication information to the terminal equipment, the value of the nzp-CSI-ResourceSetid parameter in the second indication information is set to be 02. In this way, after the terminal device receives the first indication information and the second indication information, it is determined that the values of nzp-CSI-ResourceSetid parameters in the two indication information are the same, and it is determined that the time-frequency resources included in the first resource set are the same as those included in the second resource set.

As another example, assume that the network device configures 10 NZP CSI-RS resource sets in advance for the terminal device, identifiers of the 10 NZP CSI-RS resource sets are 01 to 10, respectively, and the network device determines to use the NZP CSI-RS resource set 2 as the first resource set and the second resource set. The network device indicates the first resource set by adopting the second indication mode in S503, and when the network device sends the first indication information to the terminal device, the value of nzp-CSI-resource id parameter in the first indication information may be set to be 02; and the network equipment adopts the third indication mode in the S504 to indicate the second resource set, and when the network equipment sends second indication information to the terminal equipment, the value of the resource list parameter in the second indication information is set to be 02. In this way, after the terminal device receives the first indication information and the second indication information, it is determined that the value of the nzp-CSI-resourcesid parameter in the first indication information is the same as the value of the resourcesist parameter in the second indication information, and it is determined that the time-frequency resources included in the first resource set and the second resource set are the same.

The second implementation mode:

the identity of the first set of resources included in the first indication information is different from the identity of the second set of resources included in the second indication information.

As an example, assume that a network device configures 10 NZP CSI-RS resource sets in advance for a terminal device, identifiers of the 10 NZP CSI-RS resource sets are 01 to 10 respectively, where the NZP CSI-RS resource set 01 to the NZP CSI-RS resource set 05 are resource sets for carrying a first signal, the NZP CSI-RS resource set 06 to the NZP CSI-RS resource set 10 are resource sets for measuring a wideband or a partial frequency band by the terminal device, and the NZP CSI-RS resource set 01 and the NZP CSI-RS resource set 06 include the same NZP CSI-RS resource, which can be understood that the identifiers of the NZP CSI-RS resource set 01 and the NZP CSI-RS resource set 06 include the same NZP CSI-RS resource. If the network device indicates the first resource set by adopting the second indication mode in S503, when the network device sends the first indication information to the terminal device, the value of the nzp-CSI-resource id parameter in the first indication information may be set to be 01; and the network equipment adopts the second indication mode in the S504 to indicate the second resource set, and when the network equipment sends second indication information to the terminal equipment, the value of the nzp-CSI-ResourceSetid parameter in the second indication information is set to be 06. In this way, after the terminal device receives the first indication information and the second indication information, it is determined that identifiers of NZP CSI-RS resources included in the resource sets in the two indication information are the same, and it is determined that time-frequency resources included in the first resource set and the second resource set are the same.

In addition, it should be noted that the first indication information and the second indication information may be two independent information, for example, the network device may use the steps in S503 and S504 to generate the first indication information and the second indication information, and send the first indication information and the second indication information to the terminal device respectively. Alternatively, the first indication information and the second indication information may be the same information, that is, the first resource set and the second resource set are indicated by one information, which is not described herein.

S505, the network equipment sends third indication information, and the terminal equipment receives the third indication information.

In this embodiment of the present application, the third indication information is used to indicate a third resource set, where at least one time-frequency resource in the third resource set is used to carry a measurement result of the terminal device for measurement of the wideband or the partial frequency band.

As one example, the network device indicates the third set of resources by invoking the reportConfigId parameter in the CSI-ReportConfig =sequence { } message. For the description of the CSI-ReportConfig =sequence { } message and reportConfigId parameter, refer to the description of the third indication manner in S504, and will not be described herein.

In this embodiment of the present application, the time-frequency resources included in the first resource set, the second resource set, and the third resource set are taken as examples for illustration.

S506, the network equipment sends fourth indication information, and the terminal equipment receives the fourth indication information.

In this embodiment of the present application, the fourth indication information is used to instruct the terminal device to report a reporting manner of a measurement result of measurement performed for the wideband or the partial frequency band. Specifically, the reporting manner may include, but is not limited to, the following three manners:

the first reporting mode is periodic reporting. In the reporting manner, after obtaining the measurement result of the measurement for the wideband or the partial frequency band, the terminal device may send the measurement result on at least one time-frequency resource in the third resource set according to the configured time period.

The second reporting mode is semi-persistent reporting. In the reporting mode, the terminal device reports a measurement result for measuring the broadband or part of the frequency bands according to the trigger information of the network device. After the terminal device receives the trigger information sent by the network device, the measurement result may be sent on at least one time-frequency resource in the third resource set according to the configured time period. The trigger information may be MAC CE or DCI, which is not limited herein.

And a third reporting mode, namely reporting in an aperiodic (apidic) mode. In the reporting mode, the terminal device reports a measurement result for measuring the broadband or a part of the frequency bands according to the DCI sent by the network device. As an example, a CSI request field (CSI request field) is included in the DCI, and the field includes N bits, where N is typically an integer greater than or equal to 0 and less than or equal to 6. Each value of the field is used to indicate a NZP CSI-RS resource pattern, each corresponding to an aperiodic trigger state (aperiodic trigger state). Each aperiodic trigger state corresponds to a set of configuration parameters including a reference signal configuration (resources for channel) parameter and a reporting configuration (reportConfig) parameter, and the description of the reference signal configuration parameter and the reporting configuration parameter refers to the corresponding contents in the third indication mode in step S504, which are not described herein again. It will be appreciated that each value in the field is used to indicate a set of NZP CSI-RS resources and measurements on time-frequency resources in the set of NZP CSI-RS resources, and that the field may have a total of 2 ^N The network device can indicate 2 through this field ^N And reporting the measurement result on the time-frequency resource in the NZP CSI-RS resource set indicated in the DCI request domain by the terminal equipment.

It should be noted that, in the first reporting mode and the second reporting mode, the terminal device can only send the measurement result through the uplink control channel, and in the third reporting mode, the terminal device can only send the measurement result through the uplink shared channel.

Next, the fourth instruction information will be described.

The fourth instruction information may be information independent of the first instruction information, the second instruction information, and the third instruction information, for example, may be a DCI or a MAC CE, and the reporting mode of the terminal device is instructed by the DCI or the MAC CE.

Alternatively, the fourth instruction information and the third instruction information are the same information.

As another example, the third indication information is a CSI-ReportConfig: =sequence { } message, and the CSI-ReportConfig: =sequence { } message may further include a reportConfigType parameter, where the reporting manner of the terminal device is indicated by the parameter. For example, when the reporting mode of the network device configuration terminal device is periodic reporting, setting the content indicated by the parameter as periodic; when the reporting mode of the network equipment configuration terminal equipment is semi-persistent reporting, setting the content indicated by the parameter as semi-persistent; when the reporting mode of the network equipment configuration terminal equipment is aperiodic reporting, setting the content indicated by the parameter as apidic, and setting the resource set indicated by the reportConfigId parameter in the CSI-ReportConfig =sequence { } message to be the same as the resource set indicated by the reference signal configuration parameter in an aperiodic trigger state of the terminal equipment.

Alternatively, the fourth indication information may be the same information as the first indication information, the second indication information, and the third indication information, and the specific implementation manner may refer to the case that the fourth indication information and the third indication information are the same information, which is not described herein. In fig. 5, the first to fourth instruction information are independent information, respectively.

It should be noted that, steps S502 to S506 are optional steps, that is, they are not necessarily performed, for example, the DRX configuration information in steps S502 to S506 or the content indicated in the first indication information to the fourth indication information may be pre-agreed by the network device and the terminal device, and in this case, steps S502 to S506 may not be performed. In fig. 5, steps S502 to S506 are indicated by broken lines to indicate that these steps are optional steps.

S507, if the terminal equipment determines that DCI sent to the terminal equipment by the network equipment is not received within a preset time period, the terminal equipment enters a sleep state in the DRX cycle.

When the terminal equipment does not detect the DCI sent to the terminal equipment from the PDCCH within a period of time, the terminal equipment enters a sleep state in the DRX cycle according to the received DRX configuration information in order to save energy consumption expenditure. The preset time period is preconfigured for the terminal device and may be 60 seconds/s, for example. When the terminal equipment is in the sleep state, the terminal equipment can close the radio frequency transceiver, the baseband processing chip and the memory, only the crystal oscillator clock is reserved, and of course, the terminal equipment can also select to close other devices, and the method is not limited.

S508, the network equipment sends a first signal, and the terminal equipment detects the first signal.

When the network device determines that DCI for data transmission is to be transmitted to the terminal device in a wake-up time of an upcoming DRX cycle, the network device then transmits a first signal on time-frequency resources included in the first set of resources configured in S503. The network device may periodically transmit the first signal, may semi-continuously transmit the first signal, or may non-periodically transmit the first signal, which is not limited herein.

Generally, the first signal may be sent in an aperiodic manner, and in a specific implementation process, the network device may select the sending manner of the first signal according to a user requirement, which is not limited herein.

The first signal may be a signal of a reference signal type, for example, a signal of a channel state information measurement (CSI-RS) type, or may be a signal of another reference signal type, which is not limited herein.

The terminal device wakes up N slots before the wake-up time of the DRX cycle, and detects the first signal. The value of N may be indicated by the network device through the DRX configuration information in S502 or the first indication information in S503, or may be predetermined by the network device and the terminal device, which is not limited herein.

And S509, when the terminal equipment determines that the control channel needs to be detected according to the detection result of the first signal, the terminal equipment performs measurement on the broadband or partial frequency band.

In the embodiment of the application, the network device indicates whether the terminal device detects the control channel by whether to send the first signal, so that after the terminal device detects the first signal, it is determined that the control channel needs to be detected, and further measurement is performed for the broadband or the partial frequency band.

As can be seen from the description in the foregoing step S503 and step S504, the time-frequency resource configured by the network device for carrying the first signal is the same as the time-frequency resource configured by the terminal device for measuring the wideband or the partial frequency band, so, when the terminal device receives the first indication information and the second indication information, and determines that the time-frequency resource for carrying the first signal is the same as the time-frequency resource configured by the terminal device for measuring the wideband or the partial frequency band, the terminal device may consider that on the time-frequency resource for carrying the first signal, the terminal device not only needs to detect whether the first signal on the time-frequency resource to determine whether to monitor the control channel, but also needs to measure on the time-frequency resource for the wideband or the partial frequency band when the first signal is detected on the time-frequency resource, and as an example, the terminal device measuring on the time-frequency resource for the wideband or the partial frequency band may be understood as measuring the channel state information CSI of the wideband or the partial frequency band, and in this embodiment of the application, the terminal device measures the CSI of the first signal to realize the measurement of the channel state information CSI of the wideband or the partial frequency band.

That is, in the embodiment of the present application, the first signal has two functions, the first signal is used to indicate whether the terminal device detects the control channel, and is used to indicate that when the first signal indicates that the control channel is detected, measurement is performed on the first signal, so as to obtain a measurement result that the terminal device performs measurement for CSI of a wideband or a partial band.

In the above technical solution, a manner of multiplexing the first signal to measure for a wideband or a partial frequency band is adopted, so that resources for carrying downlink reference signals can be fully utilized, and the network device does not need to configure resources for measuring CSI for the terminal device in advance or trigger resources for measuring CSI through other signals (e.g., DCI), and the network device does not need to send reference signals for measuring CSI again, so that the number of configuration signaling used by the network device for sending the configuration signaling can be saved, the number of reference signals sent can be reduced, the signaling overhead of the network device can be reduced, and the downlink channel capacity can be improved.

The terminal device measures the first signal, which may include measuring RSRP of the first signal, RSRQ of the first signal, etc., where the content of the measurement may be pre-agreed by the network device and the terminal device, or may be indicated by the network device through the fourth indication information in step S506, which is not limited herein.

And after the terminal equipment acquires the measurement result, the measurement result is sent to the network equipment. In this embodiment of the present application, the reporting manner in which the terminal device sends the measurement result to the network device is indicated in step S506, so that the manner in which the terminal device sends the measurement result to the network device is different according to the reporting manner indicated in step S506, and each manner in which the terminal device sends the measurement result to the network device is described below.

The first transmission mode is:

referring to step S5101 in fig. 5, when the network device indicates that the reporting mode of the terminal device is periodic reporting or semi-persistent reporting, that is, the terminal device needs to send the measurement result in the uplink control channel, the terminal device executes step S5101.

S5101, after the terminal equipment enters an awake state of discontinuous reception DRX, the measurement result is sent in an uplink control channel through at least one time-frequency resource in a third resource set.

Since the first signal is sent before the wake-up time of the terminal device entering DRX, the terminal device obtains measurements for the wideband or the partial band also before the wake-up time of the terminal device entering DRX cycle. When the terminal device enters the wake-up time of the DRX cycle, i.e. is in the wake-up state, the terminal device may send the measurement result through at least one time-frequency resource in the third set of resources indicated in step S505, please refer to fig. 7, and when the terminal device enters the wake-up time, the uplink control channel is used to send the measurement result of the first signal.

As an example, the third set of resources indicated in step S505 is a NZP CSI-RS resource set 02, where the NZP CSI-RS resources in the NZP CSI-RS resource set 02 are as shown in fig. 6, that is, the third set of resources includes 2 NZP CSI-RS resources, the first NZP CSI-RS resource occupies the 3 rd OFDM symbol in one slot, occupies the 3 rd subcarrier, the 7 th subcarrier and the 11 th subcarrier in the frequency domain, respectively, and the second NZP CSI-RS resource occupies the 7 th OFDM symbol in one slot, and occupies the 3 rd subcarrier, the 7 th subcarrier and the 11 th subcarrier in the frequency domain, respectively; and in step S506, the reporting mode of the terminal device is periodic reporting, where the reporting period is reporting once every 2 timeslots, and when the terminal device is in an awake state, the measurement result is reported in the first timeslot, the third timeslot, the fifth timeslot, etc. in the uplink control channel, and in each timeslot where the measurement result needs to be reported, the measurement result is sent on 6 REs as shown in fig. 6.

In the above technical solution, since the terminal device has acquired the measurement result of measuring the CSI of the wideband or the partial band before entering the DRX awake state, after the terminal device enters the DRX awake state, the steps of receiving the reference signal for measurement from the network device and measuring the reference signal can be saved, so that the measurement result can be reported to the network device more quickly, the network device can be facilitated to know the downlink channel state of the terminal device after entering the DRX awake state earlier, for example, when the downlink channel state of the terminal device is better, the data can be sent by using the high-rate and/or large-code block mode as early as possible, so that the data transmission efficiency of the terminal device at the awake time can be improved, the terminal device can receive the data to the sleep state earlier, thereby reducing the duration of the terminal device in the awake state, and reducing the energy consumption overhead of the terminal device.

The second transmission mode:

referring to steps S5102a to S5102b in fig. 8, when the network device indicates that the reporting mode of the terminal device is aperiodic reporting, that is, the terminal device needs to send the measurement result in the uplink shared channel, the terminal device executes steps S5102a to S5102b.

S5102a, after the terminal device enters the awake state of discontinuous reception DRX, downlink control information DCI transmitted by the network device receives the DCI.

In the embodiment of the present application, the DCI is used to indicate that some or all of the time-frequency resources in the third resource set are used to send the measurement result.

Specifically, the network device may set the time-frequency resource corresponding to the value of the CSI request field of the DCI, which is all or part of the time-frequency resources in the third resource set indicated in step S505, so that when the terminal device enters the awake state and detects the DCI, it is determined to use the time-frequency resource indicated by the DCI to send the measurement result. Referring to fig. 9, when the terminal device enters the wake-up time, firstly, DCI is detected in the downlink control channel, and after the DCI is detected, the measurement result of the first signal is sent by using the uplink shared channel.

As an example, the third set of resources indicated in step S505 is the NZP CSI-RS resource set 02, where the NZP CSI-RS resources in the NZP CSI-RS resource set 02 are as shown in fig. 6, that is, the third set of resources includes 2 NZP CSI-RS resources, the first NZP CSI-RS resource occupies the 3 rd OFDM symbol in one slot, occupies the 3 rd subcarrier, the 7 th subcarrier and the 11 th subcarrier in the frequency domain, respectively, and the second NZP CSI-RS resource occupies the 7 th OFDM symbol in one slot, and occupies the 3 rd subcarrier, the 7 th subcarrier and the 11 th subcarrier in the frequency domain, respectively. The NZP CSI-RS resource pattern indicated in the DCI is the first NZP CSI-RS resource of the NZP CSI-RS resource set 02, so that the terminal device determines to use the first NZP CSI-RS resource of the NZP CSI-RS resource set 02 to send the measurement result.

S5102b, the terminal device transmits the measurement result in the uplink shared channel through at least one time-frequency resource among the time-frequency resources indicated by the DCI.

The manner in which the terminal device transmits the measurement result may be similar to that in step S5101, and will not be described again.

In the above technical solution, the network device may only need to send DCI for indicating the terminal device to report the measurement result, so that the downlink channel state after the terminal device enters the DRX awake state may be known, and steps of the network device sending a reference signal for measuring CSI to the terminal device and the terminal device measuring the reference signal may be saved, so that the measurement result may be reported to the network device more quickly, so that the network device may send data in a manner of using a high rate and/or a large code block as soon as possible, and the data transmission efficiency of the terminal device at the awake time may be improved, so that the terminal device may receive the data to return to the sleep state as soon as possible, thereby reducing the duration of the terminal device in the awake state and reducing the energy consumption overhead of the terminal device.

Third transmission method:

referring to step S5103a to step S5103b in fig. 10, when the network device does not indicate the reporting mode of the terminal device, or indicates that the reporting mode of the terminal device is periodic reporting, semi-persistent reporting, or aperiodic reporting, that is, the terminal device may send the measurement result in the uplink shared channel or send the measurement result in the uplink control channel, the terminal device performs step S5103a to step S5103b.

S5103a, after the terminal device enters an awake state of discontinuous reception DRX, the terminal device detects DCI in a preset period of time.

In the embodiment of the present application, the DCI is used to indicate that some or all of the time-frequency resources in the third resource set are used to send the measurement result. The preset time period is preset by the terminal device and the network device, or may be indicated by the network device, for example, the preset time period is 2s, which is not limited herein. The DCI is the same as the DCI in step S5102a, and will not be described here.

S5103b, when the terminal device does not detect DCI within a preset period of time, the terminal device sends the measurement result in the uplink control channel through at least one time-frequency resource in the third resource set.

Step S5103b is the same as step S5101, and will not be described again here.

It should be noted that, when the terminal device detects the DCI in the preset period, the terminal device sends the measurement result in the uplink shared channel through the time-frequency resource indicated by the DCI, and the procedure is the same as S5102b, which is not described herein, and is not shown in fig. 10, and in fig. 10, only the case that the terminal device does not detect the DCI in the preset period is taken as an example.

In the technical scheme, besides reporting the measurement result to the network equipment faster, the network equipment can conveniently use a high-rate and/or large code block mode to send data as soon as possible, the data transmission efficiency of the terminal equipment at the wake-up time can be improved, the duration of the terminal equipment in the wake-up state is reduced, and therefore the energy consumption expense of the terminal equipment is reduced.

In the above-described embodiments, the measurement of the channel state information CSI is achieved by the first signal. In an NR system, in order to improve the signal-to-noise ratio of a transmission signal, space division multiplexing and large-scale input-output (MIMO) are better implemented, so as to improve the downlink channel capacity, and a beamforming technology is introduced. Beams used for signal transmission are mainly classified into wide beams (wide beams) and narrow beams (narrow beams), wherein the wide beams have a large coverage area and a wide lobe, but the channel capacity is low, so that high-rate data cannot be transmitted; the narrow beam coverage is smaller, the channel capacity is large, and high-rate data can be sent. Therefore, after the terminal equipment enters the awakening state from the sleep state, if the network equipment can acquire the beam measurement result of the terminal equipment as early as possible, the narrow beam can be used for transmitting high-rate data as early as possible, so that the data transmission efficiency of the terminal equipment at the awakening time is improved, the terminal equipment can receive the data to return to the sleep state as early as possible, the duration of the terminal equipment in the awakening state is reduced, and the energy consumption expense of the terminal equipment is reduced. Thus, in the embodiment shown in fig. 11, a procedure for measuring a beam of a wideband or a partial band by a first signal is described, and referring to fig. 11, a flowchart of a communication method is provided for an embodiment of the present application.

In the following description, this method is applied to the network architecture shown in fig. 4 as an example, that is, the network device described below may be a network device in the network architecture shown in fig. 4, and the terminal device described below may be a terminal device in the network architecture shown in fig. 4. In addition, the method may be performed by two communication devices, for example, a first communication device and a second communication device, where the description of the first communication device and the second communication device may refer to the embodiment shown in fig. 5, and will not be repeated herein.

S1101, the terminal device accesses the network device.

S1102, the network equipment sends DRX configuration information, and the terminal equipment receives the DRX configuration information.

S1103, the network device sends first indication information, and the terminal device receives the first indication information.

S1104, the network equipment sends second indication information, and the terminal equipment receives the second indication information.

S1105, the network equipment sends third indication information, and the terminal equipment receives the third indication information.

And S1106, the network equipment transmits fourth indication information, and the terminal equipment receives the fourth indication information.

In this embodiment of the present application, the fourth indication information needs to indicate that the measurement of the first signal is beam measurement, for example, may be measurement of a beam direction corresponding to a beam used for transmitting the first signal, and the measured beam information may include RSRP, RSRQ of all beams detected by the terminal device, or RSRP, RSRQ of a part of beams, or the like. Of course, other beam information may be measured as well, without limitation.

S1107, if the terminal equipment determines that DCI sent to the terminal equipment by the network equipment is not received in a preset time period, the terminal equipment enters a sleep state in the DRX cycle.

Step S1101 to step S1107 are similar to step S501 to step S507, and are not described here again.

S1108, the network device sends a first signal, and the terminal device detects the first signal.

When the network device determines that DCI for data transmission is to be transmitted to the terminal device in a wake-up time of an upcoming DRX cycle, the network device then transmits a first signal on time-frequency resources included in the first set of resources configured in S1103. The network device may periodically send the first signal, or may semi-continuously send the first signal, or may non-periodically send the first signal, which is the same as the step S508, and will not be described herein.

Unlike in step S508, in the embodiment of the present application, the network device may send the first signal in a plurality of narrow beams in different directions, please refer to fig. 12, where the network device sends the first signal in a total of 4 narrow beams in different directions, and the 4 narrow beams in different directions may achieve a larger coverage area in total, so that it may be ensured that the terminal device can receive the first signal as much as possible.

The terminal device wakes up N slots before the wake-up time of the DRX cycle, and detects the first signal. The value of N is the same as that in step S508, and will not be described here again.

S1109, when the terminal equipment determines that the control channel needs to be detected according to the detection result of the first signal, the terminal equipment performs measurement on the broadband or partial frequency band.

In the embodiment of the application, the network device indicates whether the terminal device detects the control channel by whether to send the first signal, so that after the terminal device detects the first signal, it is determined that the control channel needs to be detected, and further measurement is performed for the broadband or the partial frequency band. As an example, the terminal device measuring on the time-frequency resource for a wideband or a partial frequency band may be understood as the terminal device measuring on the first signal. In the embodiment of the present application, the terminal device measures the first signal, which may be understood as measuring the beam direction.

That is, in the embodiment of the present application, the first signal has two functions, the first signal is used to indicate whether the terminal device detects the control channel, and is used to indicate that when the first signal indicates that the control channel is detected, measurement is performed on the first signal to obtain a measurement result that the terminal device performs measurement for the beam direction of the wideband or the partial band. The terminal device may perform measurement according to the beam information to be measured indicated in step S1106, which is not described herein.

S1110, after the terminal equipment enters the DRX wake-up state, the measurement result is sent to the network equipment, and the network equipment receives the measurement result.

Step S1110 may include, but is not limited to, three transmission modes, wherein the first transmission mode is the same as step S5101 in fig. 5, the second transmission mode is the same as steps S5102 a-S5102 b in fig. 8, and the third transmission mode is the same as steps S5103 a-S5103 b in fig. 10, and will not be repeated here. The terminal device may send the measurement result in any one of the three sending modes. In fig. 12, the terminal device transmits the measurement result in the first manner is taken as an example.

In the above technical solution, since the terminal device has acquired the measurement result for measuring the beam direction of the wideband or the partial frequency band before entering the DRX awake state, after the terminal device enters the DRX awake state, the steps of receiving the reference signal for measuring the beam direction from the network device and measuring the reference signal can be saved, so that the measurement result can be reported to the network device more quickly, the network device can know the space channel state of the terminal device after entering the DRX awake state more quickly, so that the network device can send data to the terminal device more quickly using the narrow beam with higher throughput rate, the data throughput rate can be improved, the terminal device can receive the data more quickly and return to the sleep state, thereby reducing the duration of the terminal device in the awake state and reducing the energy consumption overhead of the terminal device.

In the embodiments shown in fig. 5, 8, 10 and 11, the first signal is multiplexed to improve the data transmission efficiency, so as to reduce the duration of the terminal device in the awake state and reduce the energy consumption overhead of the terminal device. In the embodiment of the application, a method for reducing the duration of the terminal equipment in the wake-up state without multiplexing the first signal and further reducing the energy consumption overhead of the terminal equipment is further provided.
