Description

Communication method and communication device

Technical Field

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

Background

In order to reduce the energy consumption of the terminal device, in a wireless communication system, such as a long term evolution (L TE) system, a Discontinuous Reception (DRX) mechanism has been introduced, in the DRX mechanism, the terminal device includes a sleep state (or called sleep mode or called DRX _ OFF state) and an awake state (or called awake mode or called DRX _ ON state), in the sleep state, the terminal device may turn OFF a communication device 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 (PDCCH), and after detecting Downlink Control Information (DCI) sent by the network device ON the PDCCH, the terminal device receives downlink data and the like ON time-frequency resources indicated by the DCI, and thus, in the energy consumption state, the terminal device may enter the sleep state, so that the terminal device may save power due to the sleep overhead period.

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

Disclosure of Invention

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

In a first aspect, a communication method is provided, in which a terminal device first detects whether a network device sends a first signal for indicating whether the terminal device detects a control channel, the network device may previously make an agreement with the terminal device whether the terminal device detects the control channel by sending the first signal, when the network device sends the first signal, the terminal device is indicated to detect the control channel, or whether the terminal device detects the control channel by indicating content of the first signal, the network device sends the first signal, when the terminal device determines that the control channel needs to be detected according to a detection result of the first signal (which may be understood as whether the first signal or the indicating content of the first signal is detected), the first signal is further used for indicating the terminal device to measure for a wideband or a partial band, the terminal device measures the wideband or the partial band, and sends the measurement result to the network device, which may be understood as the operating bandwidth of the terminal device or a portion of the operating bandwidth of the terminal device.

In the above technical solution, the first signal may be used to indicate whether the terminal device detects the control channel, and may also be used to indicate the terminal device to measure the wideband or the partial frequency band, so that, 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 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 obtain the measurement before entering the wake-up time. Therefore, after the terminal device enters the wake-up time, the measurement result can be immediately sent to the network device, so that the network device can obtain the state of the downlink channel of the terminal device according to the measurement result, and adjust the scheduling strategy in time according to the state of the downlink channel of the terminal device.

In a possible design, the network device sends, to the terminal device, first indication information for indicating a first resource set, where at least one time-frequency resource in the first resource set is used to carry the first signal, and sends, to the terminal device, second indication information for indicating a second resource set, where 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 a time-frequency resource used for carrying the first signal is the same as a time-frequency resource used for the terminal device to measure the broadband or the partial frequency band, and then the terminal device may consider that, in the time-frequency resource used for carrying the first signal, the terminal device not only needs to detect whether there is the first signal on the time-frequency resource to determine whether the control channel needs to be monitored, but also needs to measure the broadband or the partial frequency band on the time-frequency resource when the first signal is detected on the time-frequency resource, so that the utilization rate of the time-frequency resource can 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 may be the same or different.

In the above technical solution, the terminal device may determine 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 the wideband or a 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 of 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 the flexibility of the terminal device.

In one possible embodiment, the terminal device performs measurements for a wide band or a partial band, which is to be understood as the terminal device performing measurements on the first signal. That is to say, the terminal device measures the first signal to implement measurement on the wideband or the partial frequency band, so that the network device may not send a reference signal for measuring the wideband or the partial frequency band, and may increase the capacity of the downlink channel and may reduce signaling overhead between the network device and the terminal device.

In a possible design, the second resource set includes at least one first time-frequency resource, and a time domain position of each first time-frequency resource is located after a time domain position of the first signal and before a time domain position corresponding to the terminal device entering an awake state of non-continuous DRX reception, in this case, the terminal device may detect, on the at least one first time-frequency resource, a reference signal used for the terminal device to measure a wideband or a partial frequency band, and measure the wideband or the partial frequency band by measuring the reference signal.

In the above technical solution, the terminal device may measure the wideband or the partial frequency band before entering the DRX wake-up state, or before the terminal device enters the start time of the wake-up time, so that after the terminal device enters the wake-up time, the measurement result of measuring the wideband or the partial frequency band may be reported without performing the step of measuring the wideband or the partial frequency band, and a time delay of reporting the measurement result by the terminal device may be reduced, so that the network device obtains the channel state of the wideband or the partial frequency band as early as possible, thereby improving the transmission efficiency of data, and reducing the time length of the terminal device in the wake-up state.

In one possible design, the network device sends, to the terminal device, third indication information indicating a third resource set, where the third resource set includes at least one time-frequency resource used 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 wake-up state of the discontinuous reception DRX, the measurement result is sent in the uplink control channel through at least one time-frequency resource in the third resource set, so that the network device receives 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, after the terminal device enters the DRX wake-up state, the measurement result may be directly reported in the time-frequency resource in the third resource set, which reduces the steps of the network device sending the reference signal for measuring the wideband or the partial frequency band to the terminal device and the terminal device measuring the reference signal, so that the speed of the terminal device feeding back the measurement result to the network device is faster than that in the prior art, and the network device is convenient to acquire the channel state of the wideband or the partial frequency band as soon as possible.

In a possible design, the network device first sends DCI for indicating a part or all of the time-frequency resources in the third resource set to send the measurement result, and receives the DCI after the terminal device enters an awake state of non-persistent reception DRX, and then the terminal device sends the measurement result in an uplink shared channel through at least one time-frequency resource in 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 time-frequency resource in the time-frequency resources indicated by the DCI.

In the above technical solution, the network device may acquire the downlink channel state after the terminal device enters the DRX wake-up state only by sending DCI for instructing the terminal device to report the measurement result, which may save the steps of the network device sending a reference signal for measuring the CSI to the terminal device and the terminal device measuring the reference signal, so that the measurement result may be reported to the network device more quickly.

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

In the technical scheme, the terminal equipment can report the measurement result to the network equipment more quickly, and can also report the measurement result in a plurality of ways, so that the flexibility of the terminal equipment can be improved.

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

In the above technical solution, the terminal device may measure the CSI and/or the beam direction, so that the network device may learn the channel state and/or the spatial state of the downlink channel earlier when the terminal device enters the early wake-up state of DRX, so as to send data to the terminal device earlier by using a high-rate and large-code-block sending method and/or using a narrow beam with a higher throughput rate, reduce the duration of the terminal device in the wake-up state, and reduce the energy consumption overhead of the terminal device.

This division of the protocol layers is only an example, and it may be divided in other protocol layers, for example, in the R L C layer, the functions of the R L C layer and above are set in the CU, and the functions of the protocol layers below the R L C layer are set in the DU, or in a certain protocol layer, for example, a part of the functions of the R L C layer and the functions of the protocol layers above the R L C layer are set in the CU, and the rest of the functions of the R L C layer and the functions of the protocol layers below the R L C layer are set in the DU..

In addition, the radio frequency device may be pulled away, not placed in the DU, or integrated in the DU, or partially pulled away and partially integrated in the DU, which is not limited herein.

Alternatively, the Control Plane (CP) and the User Plane (UP) of the CU may be separated and implemented by being divided into different entities, namely a control plane CU entity (CU-CP entity) and a user plane CU entity (CU-UP entity).

In the above network architecture, the signaling generated by the CU may be sent to the terminal device through the DU, or the signaling generated by the terminal device may be sent to the CU through the DU. The DU may pass through the protocol layer encapsulation directly to the terminal device or CU without parsing the signaling. In the following embodiments, if transmission of such signaling between the DU and the terminal device is involved, in this case, the transmission or reception of the signaling by the DU includes such a scenario. For example, the signaling of the RRC or PDCP layer is finally processed as the signaling of the PHY layer to be sent 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 also be considered to be sent by the DU, or by the DU and the radio frequency.

In the above embodiment, the CU is divided into network devices on the Radio Access Network (RAN) side, and in addition, the CU may also 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 implemented functions. When the above structure of CU-DU is adopted, the network device may be a CU node, or a DU node, or a base station including the CU node and the DU node.

3) Time-frequency resources, which are time-frequency resources in a wireless communication system, are generally described in units of Physical Resource Blocks (PRBs) or RBs or Resource Elements (REs). One PRB includes 2 slots (slots) in a time domain, i.e., 14 Orthogonal Frequency division multiple access (OFDM) symbols, and includes 12 subcarriers in a 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.

The DRX cycles are respectively a DRX long cycle and a DRX short cycle, wherein the DRX long cycle is integral multiple of the DRX short cycle. The network device can configure a DRX short cycle and a DRX long cycle for the terminal device, when the DRX short cycle is finished, the terminal device enters the DRX long cycle once, the network device can also only configure the DRX long cycle for the terminal device and not configure the DRX short cycle, and the configuration conditions of the DRX long cycle and the DRX short cycle are determined according to actual use requirements.

5) The control channel may be divided into an uplink control channel and a downlink control channel, where the uplink control channel may be a Physical Uplink Control Channel (PUCCH), a machine communication physical uplink control channel (MTC physical uplink control channel, mpch), a Narrowband Physical Uplink Control Channel (NPUCCH), or the like; the downlink control channel may be a Physical Downlink Control Channel (PDCCH), a machine type communication physical downlink control channel (MPDCCH), a Narrowband Physical Downlink Control Channel (NPDCCH), or the like.

6) The uplink shared channel may be a Physical Uplink Shared Channel (PUSCH), a machine communication physical uplink shared channel (MTC physical uplink shared channel, MPUSCH), a Narrowband Physical Uplink Shared Channel (NPUSCH), or the like.

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

It should be noted that the inactive timer is named as L TE, and other names may also be used when the timer is applied to other communication systems, such as NR system or other types of communication systems.

8) The terms "system" and "network" in the embodiments of the present application may be used interchangeably. The "plurality" means two or more, and in view of this, the "plurality" may also be understood as "at least two" in the embodiments of the present application. "at least one" is to be understood as meaning one or more, for example one, two or more. For example, including at least one means including one, two, or more, and does not limit which ones are included, for example, including at least one of A, B and C, then including may be A, B, C, A and B, A and C, B and C, or a and B and C. "and/or" describes the association relationship of the associated objects, meaning that there may be three relationships, e.g., a and/or B, which may mean: a exists alone, A and B exist simultaneously, and B exists alone.

Unless stated to the contrary, the embodiments of the present application refer to the ordinal numbers "first", "second", etc., for distinguishing between a plurality of objects, and do not limit the sequence, timing, priority, or importance of the plurality of objects.

Having described some of the concepts related to the embodiments of the present application, the following describes features of the embodiments of the present application.

In L TE system, the DRX mechanism includes the following features:

referring to fig. 2, in an active state of a connection state, the terminal device starts an inactive timer (inactive timer), and monitors a Physical Downlink Control Channel (PDCCH) during a time period when the inactive timer is turned on. Once the terminal device receives Downlink Control Information (DCI) for data transmission (which may be referred to as scheduling DCI) sent to the terminal device by the network 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, resulting in an inactive timer timeout, in this case, the terminal device enters a sleep state of the DRX cycle. And after the sleep time in the DRX cycle is finished, the terminal equipment is awakened to enter an awakening state, then the inactive timer is started, and the PDCCH is monitored in the time period when the inactive timer is started. If the terminal device receives DCI for data transmission sent to the terminal device by the network device on the PDCCH before the wake-up time of the DRX cycle is finished, the terminal device restarts the inactive timer, continues to monitor the PDCCH, and receives data on the time-frequency resource indicated by the DCI. If the terminal device does not receive the DCI for data transmission sent to the terminal device within the wakeup time of the DRXcycle, the terminal device enters the sleep state again when the inactive timer times out. Because the communication devices such as the radio frequency transceiver and the baseband processor 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 L TE system, when a terminal device is in an awake state, the terminal device may blindly check on PDCCH whether there is DCI for data transmission sent to the terminal device, and 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 may also be called a new radio, NR system, a network device may configure a plurality of different types of PDCCHs for the terminal device, so that the network device may send different types of DCI to the terminal device, for example, DCI for configuring an operating band of the terminal device, or DCI for configuring a demodulation reference signal (DMRS) of the terminal device, etc. in most cases, the network device may not send DCI for data transmission to the terminal device within an awake time of DRX cycle, and thus, in a next generation communication system, for example, an NR system, an improved method for saving energy consumption of the terminal device is provided, which includes the following steps:

after the terminal device enters a connected 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 the 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, and the WUS is used to indicate whether the terminal device needs to detect a PDCCH within a wake-up time (generally, a value of L is 1) of L consecutive DRX cycles, so that after the terminal device enters a sleep time of the DRX cycle, the terminal device may determine whether it needs to wake up at the wake-up time of the DRX cycle according to the WUS.

As an example, the offset between the time when the network device is configured to transmit the WUS in the WUS configuration signaling and the start time of the terminal device in the wake-up time of the DRX cycle is N slots, as shown in fig. 3, the terminal device wakes up on N slots before the start time of the wake-up time of the DRXcycle and detects the WUS on the time-frequency resource indicated in the WUS configuration signaling, if the network device may transmit DCI for transmitting data to the terminal device within continuous L wake-up times (generally, L takes a value of 1) after the WUS, the network device transmits the WUS on the time-frequency resource indicated in the WUS configuration signaling, so that, when the terminal device detects the WUS, the terminal device may wake up on L continuous drxcycles after the WUS for a PDCCH blind wake-up time, if the network device does not transmit DCI for transmitting data to the terminal device within continuous L continuous wake-up times after the WUS, the network device does not transmit DCI for transmitting data to the terminal device, so that the terminal device may not transmit the DCI for transmitting data after the wake-up time of the DRX cycle, and thus, the terminal device may not wake-up the wake-up time of the DRX cycle before the DRX cycle, so that the terminal device may not need to save the wake-up time of the DRX cycle, and thus, the terminal device may not wake-up time of the DRX cycle, which saves the DRX cycle, so that 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 that 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 an awake state, the terminal device first turns on an inactive timer and monitors a PDCCH during a time period in which the inactive timer is turned on. If the terminal device receives DCI (downlink control information) which is sent to the terminal device by the network device and is used for data transmission on the PDCCH before the wake-up time of the DRX cycle is finished, the terminal device receives data sent by the network device on time-frequency resources indicated by the DCI, after the terminal device receives the data sent by the network device, the inactive timer is restarted, and when the inactive timer is over time, the terminal device enters a sleep state again.

It can be seen from the above process that the time length of the terminal device in the wake-up state is related to the time length of the terminal device receiving the data sent by the network device in the wake-up state.

In the NR system, in order to obtain the optimal utilization efficiency of air interface resources, when the network device transmits data, the network device may match the state of a downlink channel (e.g., a Physical Downlink Shared Channel (PDSCH)) but after the terminal device enters an awake state from a sleep state, the network device does not know the state of the downlink channel of the terminal device, and therefore, in order to ensure that the terminal device can receive the data, the network device usually adopts a conservative scheduling policy, that is, transmits the data in a low-rate and small code block manner, which may cause low data transmission efficiency at the awake time of the terminal device, thereby increasing the duration of the terminal device in the awake state, and further increasing the energy consumption overhead of the terminal device.

In view of this, an embodiment of the present application provides an information sending method, in which a terminal device first detects a first signal 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 wake up to detect the control channel when the wake-up time of the discontinuous reception cycle arrives, and needs to measure the wideband or a part of the frequency band and send 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 the wideband or a part of the 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 obtain the measurement before entering the wake-up time. Therefore, after the terminal device enters the wake-up time, the measurement result can be immediately sent to the network device, so that the network device can obtain the state of the downlink channel of the terminal device according to the measurement result, and adjust the scheduling strategy in time according to the state of the downlink channel of the terminal device.

The technical scheme provided by the embodiment of the application can be applied to AN NR system, AN advanced long term evolution (L TE-A) system, a Worldwide Interoperability for Microwave Access (WiMAX), a wireless local area network (W L AN) system and the like.

In addition, the communication system may also be applied to future-oriented communication technologies, and the system described in the embodiment of the present application is for more clearly illustrating the technical solution of the embodiment of the present application, and does not form a limitation on the technical solution provided in the embodiment of the present application.

A network architecture applied in the embodiment of the present application is described below, please refer 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 only an example, and in practical applications, the network device may provide services for a plurality of 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, a core network device or a device for carrying virtualized network functions, etc. may be further included, which will be apparent to those skilled in the art and will not be described in detail herein.

The network device in fig. 4 may be AN Access Network (AN) device, such as a base station, where the access network device corresponds to a different device in a different system, such as AN eNB in AN L TE system, and may correspond to AN access network device in AN NR, such as a gNB, in AN NR system.

The technical scheme provided by the embodiment of the application is described below 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, the 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 first communication device may be a network device or a communication device capable of supporting the network device to implement the functions required by the method, and may also be other communication devices, such as a system on chip. The same applies to the second communication device, which may be a terminal device or a communication device capable of supporting the terminal device to implement the functions required by the method, but may also be other communication devices, such as a system-on-chip. The implementation manners of the first communication device and the second communication device are not limited, for example, the first communication device may be a network device, the second communication device is a terminal device, or the first communication device is a network device, and the second communication device is a communication device capable of supporting the terminal device to implement the functions required by the method, and so on.

For convenience of description, in the following, the method is performed by a network device and a terminal device as an example, that is, the first communication apparatus is a network device and the second communication apparatus is a terminal device as an example.

S501, the terminal equipment is accessed to the network equipment.

Before the terminal device communicates with the network device, the terminal device first needs to access the network device.

As an example, the terminal device may implement access by means of random access. For example, the terminal device first performs downlink synchronization, and obtains system information such as a system frame number, random access resource information, and the like from a Physical Broadcast Channel (PBCH), where in the random access resource information, resources such as time density, frequency, and sequence, which can be used by the terminal device to 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 position indicated by the random access resource information. After receiving the random access preamble, the network device sends a Random Access Response (RAR) to the terminal device, and after receiving the RAR, the terminal device interacts with the network device according to the information indicated in the RAR, thereby accessing the network device.

Of course, the terminal device may also access the network device in other manners, which is not limited herein.

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

In this embodiment of the 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, a duration of an awake time and a duration of a sleep time in the DRX short cycle and/or the DRX long cycle, and of course, other configuration information may also be included, for example, an initial value of the configuration inactivity timer, and the like, which are not illustrated herein.

The DRX configuration information may be a configuration signaling dedicated to configuring DRX, for example, Radio Resource Control (RRC) signaling or media access control element (MAC CE) signaling, and the DRX configuration information may also be included in other configuration messages, which may be RRC setup messages, RRC reestablishment messages, or RRC reconfiguration messages, and the like, which is not limited herein.

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

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

The first signal is used to indicate whether the terminal device detects a control channel, and taking the control channel as a 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 can be understood as 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 also be a null packet only including a specific packet header, or may also be a signal carrying other specific content, 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 the WUS may be a signal or a pilot carried on the PDSCH, for example, the WUS may be a constant amplitude zero auto-correlation (CAZAC) sequence, such as a Zadoff-chu (zc) sequence, a Frank sequence, a Golomb polyphase sequence, or a Chirp sequence. In the embodiments of the present application, the specific form of the first signal is not limited.

In addition, the first signal may have binomial property, 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 binomial property by transmitting the first signal and not transmitting the first signal, the network device determines that DCI corresponding to the terminal device is to be transmitted in a 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 to be transmitted in the control channel, the network device does not transmit the first signal, and the terminal device does not detect the first signal, and determines that the DCI is not to be detected in the wake-up time after the first signal, thereby determining that the control channel is not to be detected.

Alternatively, the network device may indicate the binomial according to the content carried in the first signal, that is, the network device may transmit the first signal regardless of whether the network device transmits DCI corresponding to the terminal device in a control channel, but in different cases, the content carried in the first signal is different. For example, the network device indicates the binomial property through a mask of the first signal, and the network device and the terminal device pre-stipulate that when the mask carried in the first signal is mask 1, the network device is represented that the network device will transmit DCI corresponding to the terminal device in the control channel, and when the mask carried in the first signal is mask 2, the network device is represented that the network device will not transmit DCI corresponding to the terminal device in the control channel. Therefore, after the terminal device receives the first signal, it may be determined whether the network device will send DCI corresponding to the terminal device in the control channel according to the mask in the first signal, and further determine whether to detect the control channel. Or, the network device may also directly carry information on 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 a detection control channel, the terminal device determines to detect the control channel, and if the information indicated by the first signal is a non-detection control channel, the terminal device determines not to detect the control channel. In the embodiment of the present application, the manner of indicating the binomial property of the first signal is not limited.

The specific form and the binomial indication manner of the first signal may be predetermined by the network device and the terminal device, or the network device may indicate the specific form of the first signal and the binomial indication manner of the first signal to the terminal device, for example, the DRX configuration information in S502 may be indicated to the terminal device, of course, the DRX configuration information may also be indicated to the terminal device by other information, for example, the DCI may be sent before S502 to indicate the specific form of the first signal and the binomial indication manner of the first signal to the terminal device, which is not limited herein. For convenience of explanation, hereinafter, the binomial is indicated by whether or not the first signal is transmitted, for example.

Next, the first resource set will be explained.

For convenience of description, the number of the first resource sets is taken as one example hereinafter. The first resource set may include one or more time-frequency resources, and any Resource Element (RE) in the first resource set may be understood as any resource unit in the first resource set, where the resource unit may be an RE, or a combination of multiple REs, and details are not described herein. Wherein, the RE includes one Orthogonal Frequency Division Multiplexing (OFDM) symbol in a time domain and one subcarrier in a frequency domain.

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

Please refer to fig. 6, which is an example of the first set of resources. 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 respectively in the frequency domain, that is, the code 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, respectively, in the frequency domain.

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:

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

As one 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 the following parameters:

1. NZP-CSI-RS-resource id, the parameter indicating an identifier of the NZP CSI-RS resource;

2. resource mapping, which is used for representing how the NZP CSI-RS resource is mapped to a time domain and a frequency domain;

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

4. a scrambling ID, configured to instruct a network device to generate a scrambling code for a first signal sequence used when the network device transmits a first signal on the NZP CSI-RS resource;

5. period AndOffset, the parameter is used for instructing the network equipment to send the periodic configuration information of the first signal on the NZP CSI-RS resource;

6. qcl-InfoPeriodcCSI-RS, the parameter for instructing the network equipment to transmit beam information of 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 an NZP-CSI-RS-resources set: ═ SEQUENCE { } message. The NZP-CSI-RS-resource set includes, but is not limited to, the following parameters:

1. NZP-CSI-ResourceSetId for indicating an identifier of the NZP CSI-RS resource set. 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, through the NZP-CSI-ResourceSetId parameter, a resource set configured for the terminal device by the network device to transmit 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. the retransmission is used for indicating whether the NZP CSI-RS resource is repeatedly transmitted or not and is mainly used for beam detection;

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

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

The third indication mode is as follows:

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

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

2. wakeup-offset, wherein the parameter is used for indicating an offset between a sending time of the network equipment for sending the first signal on the NZP CSI-RS resource and a starting time of a wakeup time of the terminal equipment in the DRX cycle;

in a specific implementation process, a person skilled in the art may configure an indication manner of the first indication information according to a use requirement, which is not limited herein. It should be understood that the above three indication manners are only examples of the first indication information, and should not be construed as limitations on the indication manner of the first indication information.

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

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

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

It should be noted that the terminal device performs measurement on a wideband or a partial band, and it is understood that the terminal device performs measurement on the wideband if the operating bandwidth of the terminal device is the carrier bandwidth of the entire communication system, for example, in the L TE system, the operating bandwidth of the terminal device is the same as the carrier bandwidth of the L TE system, and the terminal device performs measurement on the partial Bandwidth (BWP) in the carrier bandwidth of the NR system if the operating bandwidth of the terminal device is the partial band of the carrier bandwidth, for example, the NR system supports the terminal device to operate on the partial Bandwidth (BWP) in the carrier bandwidth of the NR system, so that the terminal device only needs to perform measurement on the partial bandwidth (or referred to as 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 described herein again. In the following, the resource in the second set of resources is taken as an example as an NZP CSI-RS resource.

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

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 repeated herein.

The third indication mode is as follows:

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

1. reportConfigId for indicating an identity of a reference signal configuration (resources for channel) parameter and an identity of a reporting configuration (reportConfig) parameter;

it should be noted that the network device may configure, in advance, a plurality of reference signal configuration parameters and a plurality of reporting configuration parameters for the terminal device, where each reference signal configuration parameter corresponds to one identifier, and each reporting configuration parameter corresponds to one identifier, where the reference signal configuration parameters are used to indicate which time-frequency resources the terminal device measures for a wideband or a partial frequency band, for example, may indicate one NZP CSI-RS resource set, and the reporting configuration parameters are used to indicate contents 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 (RSRP), Reference Signal Received Quality (RSRQ), and the like.

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

3. the resource for channel measurement is used for indicating the resources used by the terminal equipment for measuring the broadband or the partial frequency band, wherein the NZP CSI-RS resource set used for measuring the broadband or the partial frequency band is indicated by the resource set L ist in the parameter.

It should be noted that, in this embodiment of the application, the time-frequency resources included in the first resource set in S503 are the same as the time-frequency resources included in the second resource set in S504. In particular, it may be achieved, but not limited to, that the time-frequency resources comprised in the first set of resources are the same as the time-frequency resources comprised in the second set of resources in two ways:

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, assuming 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 01-10, respectively, and the network device determines to use 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 using the second indication manner in S503, and when the network device sends the first indication information to the terminal device, the value of the nzp-CSI-ResourceSetId parameter in the first indication information may be set to 02; the network device indicates the second resource set by using the second indication manner in S504, and when the network device sends the second indication information to the terminal device, the value of the nzp-CSI-ResourceSetId parameter in the second indication information is set to 02. Thus, after the terminal device receives the first indication information and the second indication information, it is determined that the values of the 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 the time-frequency resources included in the second resource set.

As another example, assuming that a network device configures 10 NZP CSI-RS resource sets to a terminal device in advance, identifiers of the 10 NZP CSI-RS resource sets are 01-10, respectively, and the network device determines to use NZP CSI-RS resource set 2 as a first resource set and a second resource set, the network device indicates the first resource set in a second indication manner in S503, when the network device sends first indication information to the terminal device, a value of a NZP-CSI-resourcetild parameter in the first indication information may be set to 02, the network device indicates the second resource set in a third indication manner in S504, when the network device sends second indication information to the terminal device, a value of a resourcet L parameter in the second indication information is set to 02, and thus, after the terminal device receives the first indication information and the second indication information, it is determined that a value of the resource set in the first indication information is the same as a value of the second resource set in the second indication information, and the time-frequency resource set of the resource set is the same as the value of the resource set in the resource set 3683-CSI-RS parameter in the first indication information, and the second indication information.

The second implementation mode comprises the following steps:

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, it is assumed 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 sets 01 to NZP CSI-RS resource set 05 are resource sets for carrying a first signal, the NZP CSI-RS resource sets 06 to NZP CSI-RS resource set 10 are resource sets for a terminal device to measure for a wideband or a partial frequency band, and the NZP CSI-RS resource sets 01 and NZP CSI-RS resource set 06 include the same NZP CSI-RS resource, which may be understood that the NZP CSI-RS resource sets 01 and NZP CSI-RS resource set 06 include the same NZP CSI-RS resource identifier. If the network device indicates the first resource set by using the second indication manner in S503, when the network device sends the first indication information to the terminal device, the value of the nzp-CSI-ResourceSetId parameter in the first indication information may be set to 01; the network device indicates the second resource set by using the second indication manner in S504, and when the network device sends the second indication information to the terminal device, the value of the nzp-CSI-ResourceSetId parameter in the second indication information is set to 06. In this way, after the terminal device receives the first indication information and the second indication information, it is determined that the identifiers of the nzp csi-RS resources included in the resource sets 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 the time-frequency resources included in the second resource set.

In addition, the first indication information and the second indication information may be two independent information, for example, the network device may generate the first indication information and the second indication information by adopting the steps in S503 and S504, 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, one information indicates the first resource set and the second resource set, which is not described herein again.

And 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 that a terminal device measures for a wideband or a partial frequency band.

As an example, the network device indicates the third set of resources by invoking a reportConfigId parameter in a CSI-ReportConfig: ═ SEQUENCE { } message. For the descriptions of the CSI-ReportConfig: ═ SEQUENCE { } message and the reportConfigId parameter, please refer to the description of the third indication manner in S504, which is not described herein again.

It should be noted that, in the embodiment of the present application, besides time-frequency resources, some other configuration information is included in the first resource set, the second resource set, and the third resource set, and the time-frequency resources included in the first resource set, the second resource set, and the third resource set are taken as an example for description in the embodiment of the present application.

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

In this embodiment of the application, the fourth indication information is used to indicate a reporting mode in which the terminal device reports a measurement result measured for a wideband or a partial frequency band. Specifically, the reporting method may include, but is not limited to, the following three methods:

the first reporting mode is periodic (periodic) reporting. In the reporting mode, after obtaining the measurement result measured 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 method is semi-persistent (semi-persistent) reporting. In the reporting mode, the terminal device reports the measurement result measured for the wideband or the partial frequency band according to the trigger information of the network device. After receiving the trigger information sent by the network device, 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 trigger information may be a MAC CE or a DCI, which is not limited herein.

The third reporting mode is aperiodic (aperiodic) reporting. In the reporting mode, the terminal device reports the measurement result measured for the wideband or the partial frequency band according to the DCI sent by the network device. As an example, the DCI includes a CSI request field (CSI request field) field, which 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 for indicating an NZP CSI-RS resource pattern, and each NZP CSI-RS resource pattern corresponds to an aperiodic trigger state (aperiodic trigger state). Each aperiodic trigger state corresponds to a set of configuration parameters, and the configuration parameters include a reference signal configuration (resources for channel) parameter and a reporting configuration (reportConfig) parameter, where for the description of the reference signal configuration parameter and the reporting configuration parameter, reference is made to corresponding contents in the third indication manner in step S504, which is not described herein again. It is to be understood that each value in this field is used to indicate one NZP CSI-RS resource set and a measurement result on a time-frequency resource in the NZP CSI-RS resource set, this wordThe segments may have a total of 2^NThe value of the seed, the network device can indicate 2 through the field^NAnd the terminal equipment reports the measurement result on the time-frequency resource in the NZP CSI-RS resource set indicated in the DCI request domain.

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 indication information may be information that is independent from the first indication information, the second indication information, and the third indication information, and may be, for example, a DCI or a MAC CE, where the DCI or the MAC CE indicates a reporting mode of the terminal device.

Or, the fourth indication information and the third indication information are the same information.

As another example, the third indication information is CSI-ReportConfig: ═ SEQUENCE { } message, then the CSI-ReportConfig: ═ SEQUENCE { } message may further include a reportConfigType parameter, and the reporting mode of the terminal device is indicated by the parameter. For example, when the reporting mode of the network device configuring the terminal device is periodic reporting, the content indicated by the parameter is set as period; 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 device configuring the terminal device is aperiodic reporting, setting the content indicated by the parameter as aperiod, and the resource set indicated by the reportConfigId parameter in the CSI-ReportConfig: ═ SEQUENCE { } message is the same as the resource set indicated by the reference signal configuration parameter in an aperiodic triggering state of the terminal device.

Or the fourth indication information may also be the same information as the first indication information, the second indication information, and the third indication information, and a specific implementation manner may refer to a case where the fourth indication information and the third indication information are the same information, which is not described herein again. In fig. 5, the first to fourth instruction information are each independent information as an example.

It should be noted that steps S502 to S506 are optional steps, that is, they are not necessarily performed, for example, the contents indicated in the DRX configuration information or the first to fourth indication information in steps S502 to S506 may be predetermined by the network device and the terminal device, in which 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, the terminal device determines that the DCI sent to the terminal device by the network device is not received in the preset time period, and then the terminal device enters a sleep state in the DRX cycle.

When the terminal device does not detect the DCI sent to the terminal device from the PDCCH within a period of time, the terminal device enters a sleep state in the DRX cycle according to the received DRX configuration information in order to save energy consumption overhead. The preset time period is preconfigured for the terminal device, and may be, for example, 60 seconds/s. When the terminal device is in the sleep state, the terminal device may turn off the rf transceiver, the baseband processing chip, and the memory, and only the crystal oscillator clock is reserved.

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

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

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

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

The terminal device wakes up N time 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 in advance by the network device and the terminal device, which is not limited herein.

S509, 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 measures the wideband or the partial frequency band.

In this embodiment of the present 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 then measurement is performed on the wideband or the partial frequency band.

As can be known from the descriptions 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 used for the terminal device to measure the wideband or the partial frequency band, and therefore, 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 the wideband or the partial frequency band, the terminal device may consider that, on the time-frequency resource used for carrying the first signal, the terminal device not only needs to detect whether there is the first signal on the time-frequency resource to determine whether the control channel needs to be monitored, and when the first signal is detected on the time-frequency resource, the terminal device also needs to measure the wideband or the partial frequency band on the time-frequency resource, as an example, the terminal device measures the wideband or the partial frequency band on the time-frequency resource, the method includes the steps that channel state information CSI of a wide band or a partial band is measured, and in the embodiment of the application, terminal equipment measures a first signal to achieve measurement of the channel state information CSI of the wide band or the partial band.

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

In the above technical solution, a manner of multiplexing the first signal to perform measurement on the wideband or a part of the frequency band is adopted, resources for carrying downlink reference signals may 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 sent by the network device may be saved and the number of reference signals sent may be reduced, thereby reducing signaling overhead of the network device and increasing downlink channel capacity.

The terminal device may measure the first signal, and may include measuring RSRP of the first signal, RSRQ of the first signal, and the like, where the content of the measurement may be predetermined 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, the reporting mode that the terminal device sends the measurement result to the network device is indicated in step S506, so that the mode that the terminal device sends the measurement result to the network device is different according to the different reporting modes indicated in step S506, and each mode that the terminal device sends the measurement result to the network device is described below.

The first transmission mode:

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 performs step S5101.

S5101, after the terminal device 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 the third resource set.

Since the first signal is transmitted before the wake-up time when the terminal device enters DRX, the terminal device obtains the measurement result for the wideband or the partial band before the wake-up time when the terminal device enters DRX cycle. When the terminal device enters the wake-up time of the DRX cycle, that is, is in the wake-up state, the terminal device may send the measurement result through at least one time-frequency resource in the third resource set 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 for the first signal.

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

In the above technical solution, since the terminal device has obtained the measurement result for measuring the CSI of the wideband or the partial frequency band before entering the DRX-wake state, after the terminal device enters the DRX-wake 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 know the downlink channel state after the terminal device enters the DRX-wake state earlier, for example, when the downlink channel state of the terminal device is good, the data can be sent in a high-rate and/or large code block manner as early as possible, the data transmission efficiency of the terminal device at the wake-up time can be improved, the terminal device can receive the data back to the sleep state earlier, and the duration of the terminal device in the wake-up state can be reduced, and the energy consumption expense of the terminal equipment is reduced.

The second transmission method:

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 performs steps S5102a to S5102 b.

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

In this embodiment, the DCI is used to indicate that part or all of the time-frequency resources in the third set of resources 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, to 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 wake-up state and detects the DCI, it is determined to send the measurement result using the time-frequency resource indicated by the DCI. Referring to fig. 9, when the terminal device enters the wake-up time, DCI is first detected in the downlink control channel, and after the DCI is detected, a measurement result of the first signal is sent using the uplink shared channel.

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

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

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

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

The third transmission mode:

referring to steps S5103a to 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 may send the measurement result in the uplink control channel, then the terminal device executes steps S5103a to S5103 b.

S5103a, after the terminal device enters the wake-up state of non-continuous DRX reception, the terminal device detects DCI within a preset time period.

In this embodiment, the DCI is used to indicate that part or all of the time-frequency resources in the third set of resources are used to send the measurement result. The preset time period is predetermined 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 is not described herein again.

S5103b, when the terminal device does not detect the DCI within the preset time period, 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 is not described herein again.

It should be noted that, when the terminal device detects DCI within the preset time period, the terminal device sends the measurement result in the uplink shared channel through the time-frequency resource indicated by the DCI, a process of the measurement result is the same as that of S5102b, which is not described herein again, and is not shown in fig. 10, and in fig. 10, the description is given by taking an example that the terminal device does not detect DCI within the preset time period as an example.

In the technical scheme, the measurement result can be reported to the network equipment more quickly, so that the network equipment can send data in a high-rate and/or large code block mode as soon as possible, the data transmission efficiency of the terminal equipment in the wake-up time can be improved, the time length of the terminal equipment in the wake-up state is reduced, the energy consumption overhead of the terminal equipment is reduced, and besides, the terminal equipment can report the measurement result in multiple modes, so that the flexibility of the terminal equipment can be improved.

In the above 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, better implement space division multiplexing and large-scale input-output (MIMO), improve the capacity of a downlink channel, and introduce a beamforming technology. Beams used for signal transmission are mainly divided into wide beams (wide beams) and narrow beams (narrow beams), wherein the wide beams have a large coverage area and wide lobes, but have low channel capacity and cannot transmit high-rate data; the narrow beam has a small coverage area and large channel capacity, and can transmit high-speed data. Therefore, after the terminal device enters the wake-up state from the sleep state, if the network device can acquire the beam measurement result of the terminal device as early as possible, the narrow beam can be used for sending high-rate data as early as possible, so that the data transmission efficiency of the terminal device at the wake-up time is improved, the terminal device can receive the data earlier and return to the sleep state, the time length of the terminal device in the wake-up state is reduced, and the energy consumption overhead of the terminal device is reduced. Therefore, in the embodiment shown in fig. 11, a process of measuring a beam of a wideband or a partial frequency band by using a first signal is described, please refer to fig. 11, which provides a flowchart of a communication method for the embodiment of the present application.

In the following description, the 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 apparatuses, for example, a first communication apparatus and a second communication apparatus, where the description of the first communication apparatus and the second communication apparatus may refer to the embodiment shown in fig. 5, and is not 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 the first indication information, and the terminal device receives the first indication information.

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

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

S1106, the network device sends fourth indication information, and the terminal device receives the fourth indication information.

It should be noted that, in the embodiment of the present application, the fourth indication information needs to indicate that the measurement on the first signal is beam measurement, for example, the measurement may be to measure a beam direction corresponding to a beam used for transmitting the first signal, and the measured beam information may include RSRP and RSRQ of all beams detected by the terminal device, or RSRP and RSRQ of partial beams. Of course, other beam information may be measured, and is not limited herein.

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

Steps S1101 to S1107 are similar to steps S501 to S507, and are not described herein 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 sent to the terminal device within the wake-up time of the upcoming DRX cycle, the network device sends a first signal on the time-frequency resources included in the first resource set configured in S1103. The network device may send the first signal periodically, may also send the first signal semi-continuously, or may send the first signal non-periodically, and the specific sending manner is the same as that in step S508, which is not described herein again.

Unlike 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, the network device sends the first signal in a total of 4 narrow beams in different directions, and the total of 4 narrow beams in different directions may achieve a larger coverage, so as to ensure that the terminal device can receive the first signal as much as possible.

The terminal device wakes up N time 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 is not described herein again.

And 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 measures the broadband or partial frequency band.

In this embodiment of the present 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 then measurement is performed on the wideband or the partial frequency band. As an example, the terminal device measures the wideband or the partial frequency band on the time-frequency resource, which may be understood as that the terminal device measures the first signal. In the embodiment of the present application, the terminal device measures the first signal, which may be understood as measuring a beam direction.

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

S1110, the terminal device sends the measurement result to the network device after entering the DRX wake-up state, and the network device receives the measurement result.

Step S1110 may include, but is not limited to, three sending manners, wherein the first sending manner is the same as step S5101 in fig. 5, the second sending manner is the same as steps S5102a to S5102b in fig. 8, and the third sending manner is the same as steps S5103a to S5103b in fig. 10, which is not described herein again. The terminal device may transmit the measurement result in any one of the three transmission modes. In fig. 12, the terminal device sends the measurement result in the first manner.

In the above technical solution, since the terminal device has obtained the measurement result of measuring the beam direction of the wideband or the partial frequency band before entering the DRX-wake state, when the terminal device enters the DRX-wake state, the steps of receiving reference signals for measuring beam directions and measuring the reference signals from the network device can be saved, thereby reporting the measurement result to the network equipment more quickly, facilitating the network equipment to acquire the space channel state after the terminal equipment enters the DRX awakening state earlier, so that the network device transmits data to the terminal device earlier using a narrow beam with a greater throughput, the data throughput rate can be improved, the terminal equipment can receive data earlier and return to the sleep state conveniently, therefore, the time length of the terminal equipment in the awakening state is reduced, and the energy consumption expense of the terminal equipment is reduced.

It should be noted that any one of the embodiments in fig. 5, fig. 8, and fig. 10 may be combined with the embodiment shown in fig. 11, that is, the first signal may be multiplexed to measure the CSI and the beam direction, so that the network device may use a high-rate and/or large code block as soon as possible, and transmit data in a narrow beam with a higher throughput rate, which may further improve the transmission efficiency of data, reduce the duration of the terminal device in the awake state, and reduce the energy consumption overhead of the terminal device.

In the embodiments shown in fig. 5, 8, 10, and 11, the transmission efficiency of data is improved by multiplexing the first signal, so as to reduce the time duration that the terminal device is in the awake state, and reduce the energy consumption overhead of the terminal device. In the embodiment of the present application, a method for reducing the time duration of the terminal device in the awake state without multiplexing the first signal so as to reduce the energy consumption overhead of the terminal device is further provided.
