Background Art

In R18, the 3rd generation partnership project (3GPP) conducted research on low power (LP) wake-up signals (WUS) to evaluate the potential for reducing power consumption of terminals equipped with low power radio (LR). Generally speaking, even if the terminal does not send or receive any data, it will consume tens of milliwatts of power, which is called idle power consumption. This idle power consumption is caused by the fact that the terminal must periodically measure and detect potential LP-WUS. Among them, LR will periodically measure and detect LP-WUS, and the main radio (MR) can be turned off when LR is active and searching for potential LP-WUS signals. LR can wake up MR to send and receive data when LP-WUS is detected.

However, each time the MR is turned on and off, additional energy is consumed. The power amplifier (PA) of the MR is turned on with a power ramp, which brings a certain delay and additional power consumption when the power changes from zero to a stable state. Therefore, it is difficult to achieve energy saving by frequently waking up the MR.

Summary of the invention

The present application provides a communication method and device to reduce the power consumption of the communication device.

In a first aspect, a communication method is provided. The method may be performed by a first communication device or a chip/chip system. The first communication device may be a network device or a terminal device. In the method, the first communication device includes a first module and a second module, and the power consumption of the first module is lower than the power consumption of the second module. The first communication device receives a low-power wake-up signal, and the low-power wake-up signal indicates that the first module is working or indicates that the second module is working. The first communication device activates the first module or the second module to send and receive data.

Based on this solution, the network device instructs the first module of the communication device to work or instructs the second module of the communication device to work through a low-power wake-up signal. Compared with the related art in which all functions are performed by the second module, the number of times the second module is woken up can be reduced, thereby avoiding frequent wake-ups of the second module and achieving energy saving.

In a possible implementation, a first communication device receives first information, the first information includes first configuration information and second configuration information, the first configuration information includes one or more of a transmission bandwidth based on data received and sent by the first module, a frequency domain resource, a period of a synchronization signal block for time-frequency domain synchronization, or the number of synchronization signal blocks for time-frequency domain synchronization. The second configuration information includes one or more of a transmission bandwidth based on data received and sent by the second module, a frequency domain resource, a period of a synchronization signal block for time-frequency domain synchronization, or the number of synchronization signal blocks for time-frequency domain synchronization.

Based on the above solution, since the capabilities and latency requirements of the first module and the second module are different, different configuration information is configured for the first module and the second module respectively through the first information, so that the first module and the second module can perform corresponding functions based on the configuration information.

DETAILED DESCRIPTION

In order to facilitate understanding of the technical solutions provided by the embodiments of the present application, the technical terms involved in the embodiments of the present application are explained and illustrated below.

1) Low power wake-up signal (LP-WUS), which is used in multiple low power communication protocols, such as long range radio (LoRa), Bluetooth or wireless fidelity (WiFi). LP-WUS allows the design and implementation of low power receivers, which helps to reduce device power consumption. LP-WUS is very similar to WUS. WUS is based on the traditional Zadoff-Chu (ZC) sequence and the downlink control information (DCI) format 2-6 in the physical downlink control channel (PDCCH). If WUS is detected, it will continue to decode the paging message, otherwise it will return to sleep and wait for the next opportunity to receive WUS.

The technical solutions of the embodiments of the present application can be applied to New Radio (NR) systems, Long Term Evolution (LTE) systems, LTE frequency division duplex (FDD) systems, LTE time division duplex (TDD) systems, Worldwide Interoperability for Microwave Access (WiMAX) communication systems, ^fifth generation communication systems (5G), next generation wireless communication systems such as 6G, etc., without limitation herein.

FIG1 is a schematic diagram of the architecture of a communication system 1000 used in an embodiment of the present application. As shown in FIG1 , the communication system includes a wireless access network 100. The wireless access network 100 may include at least one network device (such as 110a and/or 110b in FIG1 ), and may also include at least one terminal device (such as at least one of 120a-120j in FIG1 ). The terminal device is connected to the access network device wirelessly, and the access network device is connected to the core network device wirelessly or by wire. Terminal devices and terminal devices and network devices may be connected to each other by wire or wirelessly. FIG1 is only a schematic diagram, and the communication system may also include other network devices, such as wireless relay devices and wireless backhaul devices, which are not shown in FIG1 .

A network device is a network-side device with wireless transceiver functions. A network device can be a device in a radio access network (RAN) that provides wireless communication functions for terminal devices, and is called a RAN device. For example, a network device can be a base station, an evolved NodeB (eNodeB), a transmission reception point (TRP), a next-generation base station (next-generation NodeB, gNB) in a fifth-generation (5th-generation, 5G) mobile communication system, a next-generation base station in a sixth-generation (6th-generation, 6G) mobile communication system, a base station in a future mobile communication system, or an access node in a WiFi system; it can also be a module or unit that completes part of the functions of a base station, for example, a centralized unit (CU) or a distributed unit (DU). Here, the CU completes the functions of the radio resource control protocol and the packet data convergence layer protocol (PDCP) of the base station, and can also complete the function of the service data adaptation protocol (SDAP); the DU completes the functions of the radio link control layer and the medium access control (MAC) layer of the base station, and can also complete the functions of part of the physical layer or all of the physical layer. For the specific description of the above-mentioned various protocol layers, please refer to the relevant technical specifications of the 3rd Generation Partnership Project (3GPP). The network device can be a macro base station (such as 110a in Figure 1), a micro base station or an indoor station (such as 110b in Figure 1), or a relay node or a donor node, etc. The embodiments of the present application do not limit the specific technology and specific device form adopted by the network device.

In another possible scenario, multiple RAN nodes collaborate to assist the terminal in achieving wireless access, and different RAN nodes implement part of the functions of the base station respectively. For example, the RAN node can be a CU, a DU, a CU-control plane (CP), a CU-user plane (UP), or a radio unit (RU). The CU and the DU can be set separately, or can also be included in the same network element, such as a baseband unit (BBU). The RU can be included in a radio frequency device or a radio frequency unit, such as a remote radio unit (RRU), an active antenna unit (AAU), or a remote radio head (RRH).

In different systems, CU (or CU-CP and CU-UP), DU or RU may also have different names, but those skilled in the art can understand their meanings. For example, in an open radio access network (ORAN) system, CU may also be called O-CU (open CU), DU may also be called O-DU, CU-CP may also be called O-CU-CP, CU-UP may also be called O-CU-UP, and RU may also be called O-RU. For the convenience of description, CU, CU-CP, CU-UP, DU and RU are used as examples for description in this application. Any unit of CU (or CU-CP, CU-UP), DU and RU in this application may be implemented by a software module, a hardware module, or a combination of a software module and a hardware module.

Terminal equipment is a user-side device with wireless transceiver functions. Terminal equipment can also be called user equipment (UE), mobile station, mobile terminal, etc. Terminal devices can be widely used in various scenarios, such as device-to-device (D2D), vehicle to everything (V2X) communication, machine-type communication (MTC), Internet of Things (IOT), virtual reality, augmented reality, industrial control, autonomous driving, telemedicine, smart grid, smart furniture, smart office, smart wearable, smart transportation, smart city, etc. Terminal devices can be mobile phones, tablet computers, Computers, wearable devices, vehicles, drones, helicopters, airplanes, ships, robots, mechanical arms, smart home devices, etc. The embodiments of the present application do not limit the specific technology and specific device form adopted by the terminal device.

The network equipment and terminal equipment can be fixed or movable. The network equipment and terminal equipment can be deployed on land, including indoors or outdoors, handheld or vehicle-mounted; they can also be deployed on the water surface; they can also be deployed on aircraft, balloons and artificial satellites in the air. The embodiments of the present application do not limit the application scenarios of the network equipment and terminal equipment.

The roles of network devices and terminal devices can be relative. For example, the helicopter or drone 120i in FIG. 1 can be configured as a mobile network device. For the terminal devices 120j that access the wireless access network 100 through 120i, the terminal device 120i is a network device; but for the network device 110a, 120i is a terminal device, that is, 110a and 120i communicate through the wireless air interface protocol. Of course, 110a and 120i can also communicate through the interface protocol between network devices. In this case, relative to 110a, 120i is also a network device. Therefore, network devices and terminal devices can be collectively referred to as communication devices. 110a and 110b in FIG. 1 can be referred to as communication devices with network device functions, and 120a-120j in FIG. 1 can be referred to as communication devices with terminal device functions.

In the embodiments of the present application, the functions of the network device may also be performed by a module (such as a chip) in the network device, or by a control subsystem including the network device function. The control subsystem including the network device function here may be a control center in the above-mentioned application scenarios such as smart grid, industrial control, intelligent transportation, and smart city. The functions of the terminal device may also be performed by a module (such as a chip or a modem) in the terminal device, or by a device including the terminal device function. In the following, the description is made by taking the example that the functions of the terminal device are performed by the terminal and the functions of the network device are performed by the base station.

With the development of 5G technology, 5G networks have higher and higher requirements for terminal capabilities. As the requirements for terminal capabilities increase, the hardware of the terminal will increase accordingly, and the power consumption of the terminal will inevitably increase. Compared with LTE terminals, 5G terminals support a maximum power of 29dBm. Under typical services, such as comprehensive web browsing, instant messaging, games or food, the average increase in power consumption of 5G terminal communications is more than 200% compared with LTE terminals. The long-term battery life of the terminal is an important aspect of the user experience and will affect the applicability of 5G terminals or services. Therefore, the long-term battery life of 5G terminals faces great challenges, and studying how to save 5G terminal power consumption is the key to solving this problem.

Referring to Figure 2, the terminal may include a low power wake-up radio (LR) and a main radio (MR). It is understandable that LR and MR can be integrated as logical function modules on the same processor (e.g., chip), or LR and MR can be independent processors (e.g., chips). The power consumption of LR is lower than that of MR. In another example, the bandwidth of LR is also lower than that of MR. It should be noted that MR and LR are shown only as exemplary names, LR can also be called an auxiliary module, and MR can also be called a main module, which is not specifically limited in this application. In the embodiment of the present application, LR is taken as the first module and MR is taken as the second module as an example for explanation.

In R18, the 3rd generation partnership project (3GPP) conducted research on low power (LP) wake-up signals (WUS) to evaluate the potential for reducing power consumption in 5G terminals equipped with low LR. Generally speaking, 5G terminals consume tens of milliwatts of power even if they do not send or receive any data, which is called idle power consumption. This idle power consumption is caused by the fact that 5G terminals must periodically measure and detect potential LP-WUS. Among them, LR will periodically measure and detect LP-WUS, and MR can be turned off when LR is active and searching for potential LP-WUS signals. LR can wake up MR to send and receive data when LP-WUS is detected.

However, each time the MR is turned on and off, additional energy is consumed. The power amplifier (PA) of the MR is turned on with a power ramp, which brings a certain delay and additional power consumption when the power changes from zero to a stable state. For example, when performing radio resource management (RRM) measurements, the LR can receive LP-WUS and wake up the MR to perform RRM measurements. After the measurement is completed, the MR can go to sleep. For another example, after the LR receives LP-WUS, it can wake up the MR to receive and demodulate the signal. In these processes, waking up the MR will generate additional power consumption. Therefore, it is difficult to achieve energy saving by frequently waking up the main module.

In view of this, an embodiment of the present application provides a communication method. In the method, the base station instructs the first module of the terminal to work or instructs the second module of the terminal to work through a low-power wake-up signal. The terminal can then wake up the first module or wake up the second module to send and receive data. Compared with the related art in which all functions are performed by MR, the number of times MR is woken up can be reduced, so frequent MR wake-ups can be avoided, thereby achieving energy saving.

Referring to FIG. 3, an exemplary flow chart of a communication method provided in an embodiment of the present application may include the following operations. In the embodiment shown in FIG. 3, the first communication device may include a first module and a second module, and the power consumption of the first module is lower than the power consumption of the second module. In the embodiment shown in FIG. 3, the first communication device is a terminal and the second communication device is a base station.

S301: The base station sends a low-power wake-up signal to the terminal.

Correspondingly, the terminal receives a low-power wake-up signal from the base station.

In the embodiment of the present application, the low power consumption wake-up signal can be received by a low power receiver, which helps to reduce the power consumption of the device. The following description takes the low power consumption wake-up signal LP-WUS as an example.

Among them, LP-WUS indicates that the first module is working or indicates that the second module is working. For example, the low-power wake-up signal may carry a first indication information (indicator), and the first indication information indicates that the first module is working or the second module is working. It is understandable that the first indication information may be a newly added field in the low-power wake-up signal, or the existing field of the low-power wake-up signal may be reused, and this application does not make specific limitations. The following is introduced in conjunction with Table 1.

Table 1: Example of first indication information

In Table 1, when the value of the first indication information is 0, it indicates that the first module is working, and when the value of the first indication information is 1, it indicates that the second module is working. It can be understood that the correspondence between the value of the first indication information and the content in Table 1 is only shown as an example, and does not constitute a limitation on the correspondence between the value of the first indication information and the content. Conversely, when the value of the first indication information is 1, it can indicate that the first module is working, and when the value of the first indication information is 0, it can indicate that the second module is working.

S302: Activate the first module or the second module to send and receive data.

In S301, the first module may receive LP-WUS, and obtain information indicated by LP-WUS after demodulation. In the case where LP-WUS indicates that the first module is working, the first module may be awakened (wake up) based on LP-WUS, or may be activated (active) or may be turned on, and perform transceiver work, such as performing data transceiver work or performing control information transceiver work. For example, referring to FIG. 4A, LP-WUS may instruct the first module to work, LP-WUS may instruct the first module to receive a physical downlink control channel (physical downlink control channel, PDCCH) and/or a physical downlink shared channel (physical downlink shared channel, PDSCH), or LP-WUS may instruct the first module to send a physical uplink shared channel (physical uplink shared channel, PUSCH) and/or a physical uplink control channel (physical uplink control channel, PUCCH), etc.

It is understandable that the functions performed by the first module indicated by the above LP-WUS are only shown as examples, and the LP-WUS can also instruct the first module to perform other functions, such as perception, channel quality measurement, uplink positioning, downlink positioning, radio resource management (radio resource management, RRM) measurement and other functions, which are not specifically limited in this application. It is understandable that the functions performed by the first module indicated by the LP-WUS can be divided according to different channels, according to uplink and downlink divisions, or according to specific functions.

For example, due to the simple structure, large data processing delay and low power of the first module, it is suitable for use in small data transmission (SDT) scenarios with low data volume and insensitivity to delay. LP-WUS can instruct the first module to work and instruct the first module to perform SDT. Optionally, LP-WUS can also indicate the modulation and coding scheme (MCS) used for data transmission. The first module can use a low bit rate for data transmission, such as 16 quadrature amplitude modulation (QAM).

Optionally, the first module brings the problem of coverage while saving power and energy consumption, so how to enhance coverage becomes a research issue. Generally, the power spectrum density is improved by increasing the maximum number of data retransmissions or using a single subcarrier for transmission during data transmission and data reception. Using the first module usually makes data transmission and data reception work on a smaller bandwidth, which is more energy-efficient.

In the case where LP-WUS instructs the second module to work, the first module can instruct the second module to work, for example, the first module can send the acquired information to the second module, and the second module can be awakened (wake up) based on LP-WUS, or can be activated (active) or can be turned on, and perform transceiver work, such as performing data transceiver work or performing control information transceiver work, etc. For example, referring to FIG. 4B, LP-WUS can instruct the second module to work, LP-WUS can instruct the second module to receive PDCCH and/or PDSCH, or LP-WUS can instruct the second module to send PUSCH and/or PUCCH, etc.

It is understandable that the functions performed by the second module indicated by the above LP-WUS are only shown as examples, and the LP-WUS can also instruct the second module to perform other functions, such as channel quality measurement, data transmission, data reception, data initial transmission, data retransmission, etc., which are not specifically limited in this application. It is understandable that the functions performed by the second module indicated by the LP-WUS can be divided according to different channels, according to uplink and downlink divisions, or according to specific functions.

In a possible implementation, the first module generally has the characteristics of low rate, low bandwidth, and low power consumption, which means that the processing complexity is low. Therefore, in the embodiment of the present application, different configuration information can be configured for the capabilities, latency requirements, etc. of the first module and the second module. For example, the first configuration information can be configured for the first module, and the second configuration information can be configured for the second module.

The first configuration information may include one or more of the transmission bandwidth, frequency domain resources, the period of the synchronization signal and physical broadcast channel block (SSB) for time-frequency domain synchronization, or the number of SSBs. The configuration information may include one or more of the transmission bandwidth, frequency domain resources, the period of SSB used for time-frequency domain synchronization, or the number of SSBs.

It can be understood that the first configuration information and the second configuration information may be predefined by the protocol, or may be indicated by the base station. For example, if the first configuration information and the second configuration information are indicated by the base station, the base station may send the first information to the terminal, and the first information may carry the first configuration information and/or the second configuration information. Among them, the first information may be a radio resource control (RRC) signaling, such as an RRC reconfiguration (RRCreconfiguration) signaling, which is not specifically limited in this application. In one possible case, the LP-WUS may include an identifier of the first configuration information or an identifier of the second configuration information, that is, the LP-WUS may indicate which configuration information is used for sending and receiving.

In the embodiment of the present application, the transmission bandwidth in the first configuration information includes a candidate bandwidth part (wandwidth part, BWP) or BWP. It can be understood that, since the working bandwidth of the first module is smaller, the candidate BWP included in the first configuration information is smaller than the candidate BWP included in the second configuration information. Similarly, the BWP included in the first configuration information is smaller than the BWP included in the second configuration information.

In one example, the SSB period included in the first configuration information may be different from the SSB period included in the second configuration information. Similarly, the number of SSBs included in the first configuration information may be different from the number of SSBs included in the second configuration information. For example, since the first module has the characteristics of low rate, low bandwidth and low power consumption, the SSB period included in the first configuration information may be greater than the SSB period included in the second configuration information, and the number of SSBs included in the first configuration information may be less than the number of SSBs included in the second configuration information.

In another example, the frequency domain resources included in the first configuration information may be indicated by a resource block group (RBG). A larger RBG size may be configured to reduce the bit overhead of the RBG indication information. For example, the RBG size included in the first configuration information is larger than the RBG size indicated by the RBG included in the second configuration information. Optionally, the LP-WUS may carry indication information for indicating the RBG, that is, the base station may indicate which RBG to use through the LP-WUS. The following is described in conjunction with Table 2.

Table 2: An example of RBG

Table 2 shows an example of RBG in the related art. When the BWP size is 1 to 36, configuration 1 may indicate that the RBG size is 2 RBs. Then, when the BWP size is 1 to 36, there are at most 18 RBGs, that is, 18 bits are required to indicate the BWP bandwidth, such as the indication may be "100000000000000000" to indicate activation of 2 RBs for communication. Similarly, when the BWP size is 37 to 72, configuration 1 may indicate that the RBG size is 4 RBs. Then, there are at most 18 RBGs in the BWP, that is, 18 bits are required to indicate the BWP bandwidth, such as the indication may be "1000000000000000000" to indicate activation of 4 RBs for communication, and so on.

Referring to Table 3, a larger RBG size may be defined in the embodiment of the present application, that is, a RBG may include more RBs to reduce the maximum number of RBGs included in the BWP, thereby reducing the bit overhead of the RBG indication information.

Table 3: An example of RBG

In Table 3, when the BWP size is 1 to 36, configuration X may indicate that the RBG size is 16 RBs, then the BWP may contain at most 3 RBGs, and 3 bits are required to indicate the BWP bandwidth, such as "100" indicating that the first 16 RBs are activated for communication.

In another possible implementation, when performing DCI blind detection in PDCCH, when the first module performs DCI blind detection, the first module can be configured with a non-carrier coverage extension (CCE) aggregation level different from that of the second module, a control resource set (CORESET) smaller than that of the second module when performing DCI blind detection, and a search space (search space) smaller than that of the second module when performing DCI blind detection to reduce the number of PDCCH blind detections and energy consumption.

In another possible implementation, when data is sent, it is necessary to configure one or more of the time domain resources, MCS, transport block (TB) or antenna port (antenna port) for the first module in the DCI that are different from those of the second module. Line introduction.

1. Time domain resource configuration information: The first module has low energy consumption and large processing delay, so a new time domain resource configuration information list (table) can be defined for the first module to indicate the time domain resources for blind detection of DCI. Among them, the first module is associated with a time domain resource configuration information list, and the second module is associated with a time domain configuration information list. The base station can indicate which time domain resource configuration information in the list is selected through LP-WUS.

For example, the time domain resource configuration information may include one or more of K0, K1 or K2. Referring to FIG5 , K0 represents the time domain interval from the start of receiving DCI to scheduling PDSCH, K1 represents the time domain interval from the start of sending PDSCH to the start of sending acknowledgment (ACK) or non-acknowledgement (NACK), and K2 represents the time domain interval from the start of receiving DCI to scheduling uplink PUSCH.

2. MCS: The first module works in a low power consumption state and usually does not require high code rate and high-order modulation. Therefore, a new MCS list can be defined for the first module. For example, the maximum MCS configuration for data transmission is 16QAM. The base station can indicate which MCS in the MCS list to select through LP-WUS.

3. TB: The base station can configure only one TB for the first module for transmission to reduce the DCI size.

4. Antenna port: The base station can configure only a single-stream port or a dual-stream port for the first module to reduce the DCI size.

In an embodiment of the present application, LP-WUS instructs the first module to work, and when instructs the first module to perform SDT, the uplink control information (UCI) sent by the first module and the rules indicating UCI sent by the second module are different.

For example, the first module has limited processing capability and can usually only support a limited number of hybrid automatic repeat request (HARQ) processes. In one possible scenario, when using the first module to receive data, the base station can indicate through LP-WUS that the number of HARQ processes is 2 or a range, such as 2 to 4.

For another example, the uplink feedback of the first module usually does not need to support high-rank transmission. The base station can use the LP-WUS to indicate that the precoding matrix indicator (PMI) supports precoding matrices with a rank ≤ 2, thereby reducing the number of feedback bits.

For another example, the channel quality indicator (continuous quality indicator, CQI) carried in the UCI is usually 5 bits. In the embodiment of the present application, the base station can reduce the number of feedback bits by indicating that the bits occupied by the CQI are 2 bits through LP-WUS.

For another example, in an embodiment of the present application, the time-frequency domain resources of PUCCH can be configured for the first module, and the time-frequency domain resources of PUCCH can be indicated by LP-WUS. For example, a new table is added to describe the PUCCH symbol position, frequency domain offset, and cyclic shift size, and LP-WUS is used to indicate which PUCCH symbol position, frequency domain offset, and cyclic shift size in the table is used. Alternatively, for the time-frequency domain resources of PUCCH of the first module, the table of PUCCH time-frequency domain resources in the related technology can also be reused, and LP-WUS is used to indicate which PUCCH symbol position, frequency domain offset, and cyclic shift size in the table is used.

For another example, since scheduling PUSCH requires additional signaling overhead, the base station may indicate that UCI is reported on the PUCCH channel through LP-WUS.

In the embodiment of the present application, the LP-WUS can instruct the second module to work, such as instructing the second module to send and receive data. For example, big data can be sent and received by the second module.

In one possible implementation, LP-WUS may indicate the working duration of the second module. For example, LP-WUS may indicate the start time and the shutdown time of the second module to indicate the working duration of the second module. For another example, the first information may indicate the start time of the timer and the end time of the timer, and the duration between the start time and the end time may be understood as the working duration of the second module. For example, the start time may be the time when the second module is activated. Optionally, LP-WUS may also indicate the update rules for the start time or the end time of the timer. For example, if no DCI is received within a period of time, the timer may be terminated early.

Referring to Figure 6, LP-WUS indicates that the second module is working, and LP-WUS indicates a timer, as well as the start time and end time of the timer. The second module can be activated and start the timer. If DCI is received within a period of time, the second module can blindly detect DCI and demodulate DCI to obtain DCI scheduling information. The second module can perform corresponding functions based on the scheduling of DCI, such as sending or receiving data. And at the end time of the timer, the timer is terminated and turned off or sleep. If DCI is not received within a period of time, the second module can terminate the timer in advance and turn off or sleep to achieve the purpose of energy saving.

Optionally, the LP-WUS may indicate whether there is DCI within a period of time. For example, the LP-WUS may carry 1-bit indication information, and when the value of the 1-bit indication information is 0, it indicates that there is DCI within a period of time, and when the value of the 1-bit indication information is 1, it indicates that there is no DCI within a period of time. Conversely, when the value of the 1-bit indication information is 1, it indicates that there is DCI within a period of time, and when the value of the 1-bit indication information is 0, it indicates that there is no DCI within a period of time.

If LP-WUS indicates that there is no DCI for a period of time, the second module can terminate the timer in advance and shut down or sleep for a period of time. To achieve the purpose of energy saving.
