Technical Field

[0001] The present application relates to the field of communication technology, and in particular to a communication method, device, and computer-readable storage medium. Background Art

[0002] In recent years, with the continuous development of the fifth-generation (5G) communication system, data transmission latency has been continuously reduced and transmission capacity has been increasing. 5G communication systems have gradually penetrated into some multimedia services with strong real-time requirements and large data capacity requirements, such as video transmission, cloud gaming (CG), and extended reality (XR).

[0003] These multimedia services have a large data volume. Due to limited transmission resources, access network equipment can only dispatch a small number of terminal devices to transmit multimedia service data. Therefore, how to improve system capacity is a technical problem that needs to be solved urgently. Summary of the Invention

[0004] The present application discloses a communication method, apparatus, and computer-readable storage medium, which are beneficial to improving system capacity by transmitting scheduling information within a measurement time period, thereby supporting more terminal devices to transmit multimedia service data.

[0005] In the first aspect, the present application provides a communication method, which can be applied to a first terminal device, or to a device in the first terminal device (for example, a chip, or a chip system, or a circuit), or a device that can be used in combination with the first terminal device. The following description is given by taking the application to the first terminal device as an example. The method may include: receiving a first DCI, the first DCI including an indication field for at least one terminal device, the at least one terminal device including a first terminal device, the indication field including a first indication field for the first terminal device, the first indication field carrying first indication information, the first indication information indicating that the first terminal device monitors scheduling information in a first measurement time period within a first CDRX cycle, and the scheduling information is used to schedule uplink and downlink channels or uplink and downlink signals.

[0006] In this technical solution, the first terminal device can monitor the scheduling information within the first measurement time period within the first CDRX cycle. The scheduling information can be used to schedule uplink and downlink channels or uplink and downlink signals. Furthermore, after receiving the scheduling information, the first terminal device can transmit uplink and downlink channels or uplink and downlink signals based on the scheduling information, wherein the uplink and downlink channels or uplink and downlink signals can carry uplink and downlink multimedia service data, which is conducive to improving the system capacity, and thus is conducive to supporting more terminal devices to transmit multimedia service data in multimedia service scenarios.

[0008] In one implementation, the method further includes: monitoring multiple DCIs, where a monitoring interval between two adjacent DCIs in the multiple DCIs is a first duration, and the first DCI is one DCI in the multiple DCIs.

[0009] In one implementation, the plurality of DCIs are associated with a plurality of CDRX cycles, and the first DCI is associated with a first CDRX cycle of the plurality of CDRX cycles.

[0010] In one implementation, the multiple DCIs are all group DCIs.

[0011] In this technical solution, the group DCI can indicate at least one terminal device, which is conducive to further improving the system capacity.

[0015] In one implementation, the second indication information is carried by at least one second bit in the first indication field, wherein the value of one second bit in the at least one second bit is used to indicate whether the first terminal device listens to the scheduling information within one measurement time period in the at least one measurement time period.

[0022] In this technical solution, the fourth indication information is used to indicate in which time unit or time units corresponding to which SSBs in the first measurement time period the scheduling information is to be monitored. When the scheduling information is monitored and received, the uplink and downlink channels or uplink and downlink signals are transmitted based on the scheduling information, which is conducive to improving the system capacity.

[0058] The specific embodiments of the present application are further described in detail below with reference to the accompanying drawings.

[0059] The terms "first" and "second" and the like in the specification, claims, and drawings of this application are used to distinguish between different objects, not to describe a particular order. Furthermore, the terms "including" and "having," and any variations thereof, are intended to cover non-exclusive inclusions. For example, a process, method, system, product, or apparatus comprising a series of steps or elements is not limited to the listed steps or elements, but may optionally include steps or elements not listed, or may optionally include other steps or elements inherent to the process, method, product, or apparatus.

[0060] References to "embodiments" herein mean that a particular feature, structure, or characteristic described in connection with the embodiments may be included in at least one embodiment of the present application. The appearance of this phrase in various places in the specification does not necessarily refer to the same embodiment, nor does it constitute an independent or alternative embodiment that is mutually exclusive of other embodiments. It is understood, both explicitly and implicitly, by those skilled in the art that the embodiments described herein may be combined with other embodiments.

[0061] In this application, "at least one (item)" refers to one or more, "more than one" refers to two or more, "at least two (items)" refers to two or three and more than three, and "and / or" is used to describe the association relationship of associated objects, indicating that three relationships may exist. For example, "A and / or B" can mean: only A exists, only B exists, and A and B exist at the same time, where A and B can be singular or plural. The character " / " generally indicates that the previous and next associated objects are in an "or" relationship. "At least one of the following items" or similar expressions refers to any combination of these items, including any combination of single items or plural items. For example, at least one of a, b or c can mean: a, b, c, "a and b", "a and c", "b and c", or "a and b and c", where each of a, b, c can be an element or a set containing one or more elements.

[0062] In this application, "sending information to... (e.g., a terminal device)" can be understood as the destination of the information being the terminal device. This can include sending information to the terminal device directly or indirectly. "Receiving information from... (e.g., a terminal device)" or "receiving information from... (e.g., a terminal device)" can be understood as the source of the information being the terminal device, which can include receiving information from the terminal device directly or indirectly. The information may be processed as necessary between the source and destination of the information, such as format changes, but the destination can understand the valid information from the source. Similar expressions in this application can be understood similarly and will not be elaborated on here.

[0063] In the description of this application, "indication" may include direct indication and indirect indication, and may also include explicit indication and implicit indication. The information indicated by a certain information (such as the indication information described below) is called information to be indicated. In the specific implementation process, there are many ways to indicate the information to be indicated. For example, the information to be indicated can be directly indicated, such as indicating the information to be indicated itself or the index of the information to be indicated. For another example, the information to be indicated can also be indirectly indicated by indicating other information, and there is an association between the other indicated information and the information to be indicated. For another example, only a part of the information to be indicated can be indicated, while the other parts of the information to be indicated are known or agreed in advance. In addition, the indication of specific information can be achieved by means of the pre-agreed (such as specified in the protocol) order of arrangement of each information, thereby reducing the indication overhead to a certain extent.

[0064] To better understand the embodiments of the present application, the following first introduces the system architecture involved in the embodiments of the present application:

[0065] The embodiments of the present application can be applied to communication systems evolved after 5G, such as long term evolution (LTE) systems, fifth generation mobile communication (5G) systems, sixth generation mobile communication (6G) systems, satellite communications, and short-range wireless communication systems. Among them, the wireless communication systems mentioned in the embodiments of the present application include but are not limited to: three major application scenarios of 5G / 6G mobile communication systems: enhanced mobile broadband (eMBB), ultra reliable low latency communication (URLLC) and massive machine type communication (mMTC), long range Internet of Things (LoRa) systems or vehicle networking systems. The wireless communication system may include one or more access network devices, and one or more terminal devices.

[0066] Below is Figure 1 The system architecture shown in the figure is explained as an example. Figure 1 As shown, the communication system 1000 includes a radio access network (RAN) 100 and a core network (CN) 200. The RAN 100 includes at least one access network device (e.g. Figure 1 110a and 110b in, collectively referred to as 110) and at least one terminal device (such as Figure 1 120a-120j in the figure, collectively referred to as 120). The RAN 100 may also include other RAN nodes, such as wireless relay devices and / or wireless backhaul devices ( Figure 1 (not shown) etc. Terminal device 120 is wirelessly connected to access network device 110. Access network device 110 is wirelessly or wiredly connected to core network 200. The core network device in core network 200 and access network device 110 in RAN 100 can be separate physical devices, or they can be a single physical device that integrates core network logical functions and radio access network logical functions.

[0067] It should be noted that the RAN 100 may be a cellular system related to the 3rd Generation Partnership Project (3GPP), such as a 4G or 5G mobile communication system, or an evolved system after 5G (such as a 6G mobile communication system). The RAN 100 may also be an open access network (open RAN, O-RAN or ORAN), a cloud radio access network (CRAN), etc. The RAN 100 may also be a communication system that integrates two or more of the above systems. It should be noted that Figure 1 The number of access network devices and terminal devices is only for illustration and should not be considered as a specific limitation of the present application. The terminal devices and access network devices involved in the system architecture are described in detail below.

[0068] 1. Terminal Equipment

[0069] Terminal devices can also be called user equipment (UE), mobile stations (MS), mobile terminals (MT), etc. They are devices used to provide voice or data connectivity to users, or they can be IoT devices. For example, terminal devices include handheld devices with wireless connectivity, in-vehicle devices, etc. Currently, terminal devices may include: mobile phones, tablet computers, laptop computers, PDAs, mobile internet devices (MIDs), wearable devices, in-vehicle devices (e.g., cars, bicycles, electric vehicles, airplanes, ships, trains, high-speed trains, etc.), satellite terminals, virtual reality (VR) devices, augmented reality (AR) devices, smart point-of-sale (POS) machines, customer-premises equipment (CPE), wireless terminals in industrial control, smart home devices (e.g., refrigerators, televisions, air conditioners, electric meters, etc.), intelligent robots, robotic arms, workshop equipment, wireless terminals in unmanned driving, wireless terminals in telemedicine, wireless terminals in smart grids, wireless terminals in transportation safety, wireless terminals in smart cities, wireless terminals in smart homes, and flying devices (e.g., intelligent robots, hot air balloons, drones, airplanes). Terminal devices may also be other devices with terminal functions, for example, devices that function as terminals in D2D communication.

[0070] As an example and not a limitation, the wearable devices in the embodiments of the present application may also be referred to as wearable smart devices, which are a general term for wearable devices that are intelligently designed and developed using wearable technology for everyday wear, such as glasses, gloves, watches, clothing, and shoes. A wearable device is a portable device that is worn directly on the body or integrated into the user's clothes or accessories. Wearable devices are not just hardware devices, but also achieve powerful functions through software support, data interaction, and cloud interaction. Broadly speaking, wearable smart devices include those that are fully functional, large in size, and can achieve complete or partial functions without relying on smartphones, such as smart watches or smart glasses, as well as those that only focus on a certain type of application function and need to be used in conjunction with other devices such as smartphones, such as various smart bracelets and smart jewelry for vital sign monitoring.

[0071] The embodiments of this application do not limit the device form factor of the terminal device. The device used to implement the functions of the terminal device can be the terminal device; it can also be a device that supports the terminal device to implement the functions, such as a chip system. The device can be installed in the terminal device or used in conjunction with the terminal device. In the embodiments of this application, the chip system can be composed of a chip or include a chip and other discrete components.

[0072] 2. Access Network Equipment

[0073] An access network device is a node in a radio access network (RAN), and can also be called a network device or a RAN node (or device). An access network device is used to help terminal devices achieve wireless access. The multiple access network devices 110 in the communication system 1000 can be nodes of the same type or different types. In some scenarios, the roles of the access network device 110 and the terminal device 120 are relative, for example, Figure 1 The network element 120i can be a helicopter or a drone, which can be configured as a mobile base station. For the terminal devices 120j that access the RAN 100 through the network element 120i, the network element 120i is a base station; but for the base station 110a, the network element 120i is a terminal device. The access network device 110 and the terminal device 120 are sometimes referred to as communication devices, for example Figure 1 The network elements 110a and 110b may be understood as communication devices having base station functions, and the network elements 120a-120j may be understood as communication devices having terminal functions.

[0074] In one possible scenario, the access network device may be a base station, an evolved NodeB (eNodeB), a transmitting and receiving point (TRP), a transmitting point (TP), a next generation NodeB (gNB), a next generation base station in a sixth generation (6G) mobile communication system, a base station in a future mobile communication system, a satellite, an integrated access and backhaul (IAB) node, a mobile switching center, or an access network device in a non-terrestrial network (NTN) communication system, that is, it may be deployed on a high altitude platform or satellite, etc. The access network device may be a macro base station (such as Figure 1 110a in), micro base stations or indoor stations (such as Figure 1 110b in the example above), a relay node or donor node, or a wireless controller in a CRAN scenario. Access network devices can also be devices that function as base stations in device-to-device (D2D) communications, vehicle-to-vehicle (V2I) communications, drone communications, and machine-to-machine communications. Alternatively, access network devices can be servers, wearable devices, vehicles, or onboard devices. For example, in vehicle-to-everything (V2X) technology, access network devices can be roadside units (RSUs).

[0075] All or part of the functions of the access network device in this application may also be implemented through software functions running on hardware, or through virtualization functions instantiated on a platform (such as a cloud platform). The access network device in this application may also be a logical node, logical module, or software that can implement all or part of the functions of the access network device.

[0076] In another possible scenario, multiple access network devices collaborate to assist terminal devices in achieving wireless access, and different access network devices respectively implement part of the functions of the base station. For example, the access network device can be a centralized unit (CU), a distributed unit (DU), a CU-control plane (CP), a CU-user plane (UP), or a radio unit (RU). The CU and DU can be set separately, or they 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). It can be understood that the access network device can be a CU node, a DU node, or a device including a CU node and a DU node. In addition, the CU can be divided into an access network device in the access network RAN, or the CU can be divided into an access network device in the core network CN, which is not limited here.

[0077] 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 the 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, this application uses CU, CU-CP, CU-UP, DU and RU as examples for description. Any unit of CU (or CU-CP, CU-UP), DU and RU in this application can be implemented by a software module, a hardware module, or a combination of a software module and a hardware module.

[0078] In the embodiments of the present application, the form of the access network device is not limited. The device used to implement the functions of the access network device can be the access network device; it can also be a device that supports the access network device to implement the functions, such as a chip system. The device can be installed in the access network device or used in conjunction with the access network device.

[0079] In order to facilitate understanding of the contents of this solution, some concepts or technologies involved in the embodiments of this application are explained below to facilitate understanding by those skilled in the art. This part is only for ease of understanding and cannot be regarded as a specific limitation of this application.

[0080] (1) XR business

[0081] Real-time broadband communication (RTBC) in future communication systems aims to support high bandwidth and low interaction latency. This allows for increased bandwidth within given latency and reliability requirements, creating an immersive experience for users interacting with the virtual world. XR technology is a technology that enables the interaction between virtual and real life, encompassing virtual reality (VR), augmented reality (AR), and mixed reality (MR). VR, AR, and MR are collectively referred to as XR. XR services refer to those based on XR technology.

[0082] During the downlink transmission of XR services, the server's XR content module generates data content at a fixed frequency (e.g., 30Hz, 60Hz, 120Hz, etc.) and transmits it to the XR terminal device through the network device. During the uplink transmission of XR services, devices such as AR terminal devices or MR terminal devices can capture the current scene image through the built-in camera and continuously upload the current scene image at a specific frequency (e.g., 60Hz).

[0083] XR services are primarily video services, and video data is generated in bursts, meaning that data for the same service is generated periodically. For example, if 1 second (s) contains 60 frames of video data, then a video frame is generated every 16.6 milliseconds (ms). Because the data size of a video frame is so large, it is split into dozens of Internet Protocol (IP) packets. In other words, XR data is large.

[0084] For networks transmitting XR services, dozens of IP packets must be transmitted every 16.6ms, and the arrival time of these IP packets is uncertain. The difference between the arrival time of an IP packet and a periodic time point (e.g., 0ms, 16.6ms, 33.2ms, etc.) is roughly in the range of [-4, 4]ms or [-5, 5]ms, and follows a truncated Gaussian distribution. This range of [-4, 4]ms or [-5, 5]ms can be considered jitter.

[0085] (2) Measurement

[0086] Measurement is a crucial process in mobile communication systems. By measuring the signal quality of the serving cell and neighboring cells, a terminal device can determine whether to reselect to a neighboring cell. Measurements can be categorized as intra-frequency and inter-frequency.

[0087] Co-frequency measurement means that the frequency points of the terminal device's serving cell and the frequency points of the neighboring cell are on the same carrier frequency point. For example, if the frequency points of the terminal device's serving cell and the neighboring cell are both on the same frequency point within the FR2 frequency band, the terminal device can perform co-frequency measurement. Among them, the 5G frequency band is divided into FR1 and FR2. Among them, the operating frequency range of the FR1 band is 450MHz to 6GHz, and it is widely used for mobile communications in urban and rural areas. The operating frequency range of the FR2 band is 24.25GHz to 52.6GHz, and it is mainly used in high-speed mobile communications and indoor coverage scenarios.

[0088] Inter-frequency measurement means that the frequency of the terminal device's serving cell and the frequency of the neighboring cell are not on the same carrier frequency.

[0089] (3) Measurement gap

[0090] Currently, network equipment can configure neighboring cell measurement methods for terminal devices based on their capabilities, such as inter-frequency and inter-system measurement control tasks. These methods can be broadly categorized into two types: Cell Measurement Method 1: Neighboring cell measurement based on gaps (measurement gaps). Within the measurement gap, the terminal device interrupts data transmission and reception with the serving cell to perform neighboring cell measurements. Cell Measurement Method 2: Neighboring cell measurement based on no gaps (no gaps), i.e., measurements not based on measurement gaps.

[0091] The measurement gap can be understood as a period of time reserved for the terminal device to receive signals from neighboring cells and complete measurements. During the measurement gap, the original serving cell does not schedule uplink and downlink transmissions. When the measurement gap ends, the terminal device resumes communication with the original serving cell.

[0092] Measuring GAP can be used to perform inter-frequency measurements and inter-system measurements. Inter-system measurements refer to when the terminal device's serving cell and neighboring cell are cells in different systems. In other words, the terminal device's serving cell and neighboring cell belong to cells of different standard systems, for example, the serving cell is an NR cell and the neighboring cell is an LTE cell.

[0093] It should be noted that when the frequency of the serving cell and the frequency of the neighboring cell are at the same carrier frequency (i.e., in the same-frequency measurement scenario), but the subcarrier spacing (SCS) of the serving cell is different from that of the neighboring cell, the terminal device also needs to complete the neighboring cell measurement based on the measurement GAP.

[0094] The parameters for measuring GAP configured by the network device for the terminal device may include but are not limited to: the duration of measuring GAP, the period of measuring GAP, etc.

[0095] The terminal device can determine the system frame and subframe for measuring GAP based on the following formula:

[0096] SFN mod T=FLOOR(gapOffset / 10)

[0097] subframe=gapOffset mod 10

[0098] T=MGRP / 10

[0099] SFN represents the system frame; subframe represents the subframe; MGRP represents the period for measuring the GAP; gapOffset represents the offset value of the GAP mode, which can be configured in the GapConfig information element; FLOOR represents rounding down; and mod represents the modulo operation.

[0100] (4) Synchronization Signal / PBCH Block (SSB)

[0101] The SSB consists of primary synchronization signals (PSS), secondary synchronization signals (SSS) and physical downlink broadcast channel (PBCH).

[0102] The number of SSBs varies across frequency bands. For example, for sub-3G, frequency division duplexing (FDD) and time division duplexing (TDD) below 2.4G, a maximum of 4 SSBs are defined, while for TDD above 2.4G, a maximum of 8 SSBs are defined. For sub-3G to sub-6G, a maximum of 8 SSBs are defined, and for sub-6G and above, a maximum of 64 SSBs are defined.

[0103] In the time domain, one SSB occupies 4 orthogonal frequency-division multiplexing (OFDM) symbols; in the frequency domain, one SSB occupies 20 consecutive physical resource blocks (PRBs). The symbols and PRBs occupied by the specific PSS, SSS, and PBCH are not limited in the embodiments of the present application. In the time domain, within half a frame (i.e., 5ms), the number and position of SSBs are determined according to the subcarrier spacing and frequency band; multiple SSBs within a half frame form an SS burst set. The SS burst set includes the SSBs required to complete a beam scan. One SSB in an SS burst set corresponds to the direction of a beam scan, or in other words, one SSB in an SS burst set corresponds to a beam. The SS burst set is sent at a certain period.

[0104] Among them, for the SSB included in the half-frame, the index of the first symbol of each SSB can be determined according to the sub-carrier space (SCS) of the SSB, as shown below:

[0105] Case A: 15 kHz SCS, the index of the first symbol of each SSB is {2, 8} + 14·n. For operation without shared spectrum channel access: for carrier frequencies less than or equal to 3 GHz, n = 0, 1; for carrier frequencies within FR1 greater than 3 GHz, n = 0, 1, 2, 3. For operation with shared spectrum channel access: n = 0, 1, 2, 3, 4.

[0106] Case B: 30 kHz SCS, the index of the first symbol of each SSB is {4, 8, 16, 20} + 28·n. For carrier frequencies less than or equal to 3 GHz, n = 0; for carrier frequencies greater than 3 GHz within FR1, n = 0, 1.

[0107] Case C: 30 kHz SCS, the index of the first symbol of each SSB is {2, 8} + 14·n. For operation without shared spectrum channel access: For paired spectrum operation, for carrier frequencies less than or equal to 3 GHz, n = 0, 1; for carrier frequencies within FR1 greater than 3 GHz, n = 0, 1, 2, 3. For unpaired spectrum operation, for carrier frequencies less than 1.88 GHz, n = 0, 1; for carrier frequencies within FR1 greater than or equal to 1.88 GHz, n = 0, 1, 2, 3. For operation using shared spectrum channel access: n = 0, 1, 2, 3, 4, 5, 6, 7, 8, 9.

[0108] Case D: 120 kHz SCS, the index of the first symbol of each SSB is {4, 8, 16, 20} + 28·n. For carrier frequencies in FR2, n = 0, 1, 2, 3, 5, 6, 7, 8, 10, 11, 12, 13, 15, 16, 17, 18.

[0109] Case E: 240 kHz SCS, the index of the first symbol of each SSB is {8, 12, 16, 20, 32, 36, 40, 44} + 56·n. For carrier frequencies within FR2-1, n = 0, 1, 2, 3, 5, 6, 7, 8.

[0110] Case F: 480 kHz SCS, the index of the first symbol of the candidate SS / PBCH block is {2, 9} + 14·n. For carrier frequencies in FR2-2, n = 0, 1, 2, 3, 4, 5, 6, 7, 8, 9, 10, 11, 12, 13, 14, 15, 16, 17, 18, 19, 20, 21, 22, 23, 24, 25, 26, 27, 28, 29, 30, 31.

[0111] For example, based on Case A, 15KHz SCS, for a carrier frequency less than or equal to 3GHz without shared spectrum channel access, when n=0, the indices of the first symbols of the two SSBs in a time slot are 2 and 8 respectively; when n=1, the indices of the first symbols of the two SSBs in a time slot are 16 and 22 respectively.

[0112] (5)SMTC window

[0113] To avoid unnecessary measurements and reduce power consumption in terminal devices, an SSB-based measurement timing configuration (SMTC) window can be defined in the SS burst set. Network devices use the SMTC window to inform terminal devices of the measurement period and timing for SSB measurements. In other words, SMTC is a window configured by the network for terminal devices to perform SSB measurements. Terminal devices only need to perform SSB measurements within the SMTC window and do not need to perform SSB measurements outside the SMTC window. The SMTC period and offset can be configured based on the SSB period and offset. Terminal devices measure NR SSBs based on the SMTC window configured on the network side and can configure SMTCs for SSBs at different frequencies. For connected intra-frequency measurements, the network can configure up to two SMTC windows for terminal devices on a single frequency. For connected inter-frequency measurements, the network can configure up to one SMTC window for each frequency. The configuration parameters of an SMTC window include: SMTC timing: The period and offset information of the SMTC window. The SMTC period can be 5, 10, 20, 40, 80, or 160 ms. SMTC duration: The length of the SMTC window. The granularity of the SMTC window length is also 1 ms, and the length can be 1, 2, 3, 4, or 5 meters.

[0114] For example, see Figure 2 A schematic diagram of sending SSB in the SMTC window is shown. Figure 2 For example, if the SS burst period is 20 milliseconds (ms), one SS burst includes one SMTC window, the SMTC window is 5 ms, and the subcarrier spacing of the cell transmitting the SSB is 30 kHz, then the slot length is 0.5 ms when the subcarrier spacing is 30 kHz. Therefore, one SMTC window can include 10 slots. One slot includes 14 orthogonal frequency-division multiplexing (OFDM) symbols.

[0115] Figure 2 In the example, the frequency point of the cell sending SSB belongs to the Sub3G~Sub6G frequency band. Therefore, the cell can send up to 8 SSBs in the SMTC window. The cell can send a total of 8 SSBs in 4 time slots (such as time slot 0 to time slot 3) in the SMTC window. 2 SSBs are sent in each of the 4 time slots. One SSB occupies 4 OFDM symbols. The specific symbols and resource blocks (RBs) occupied by PSS, SSS and PBCH are not limited in the embodiment of the present application.

[0116] In other examples, if Figure 2 If the subcarrier spacing of a cell transmitting SSBs is 120 kHz, the time slot length is 0.125 ms, and an SMTC window can include 40 time slots. If the frequency point of the cell is in the Sub6G band or higher, then the cell can send a maximum of 64 SSBs in the SMTC window. The cell can send a total of 64 SSBs in 32 time slots within the SMTC window, with 2 SSBs in each time slot.

[0117] It is understandable that when the terminal device measures the serving cell, specifically, it measures the SSB from the serving cell within the SMTC window. In this case, Figure 2 The SSB shown is the SSB sent by the serving cell.

[0118] When the terminal device measures the neighboring cell, it specifically measures the SSB from the neighboring cell within the SMTC window.

[0119] If the frequency point of the neighboring cell is not in the same carrier frequency point as the frequency point of the serving cell, and / or the subcarrier spacing of the neighboring cell is different from the subcarrier spacing of the serving cell, the terminal device needs to measure the SSB from the neighboring cell within the SMTC window within the measurement GAP.

[0120] For example, the relationship between the measurement GAP and the SMTC window can be found in Figure 3 shown. Figure 3 Take the measurement of GAP duration as 6ms as an example, Figure 3 See the SMTC window in Figure 2 In this case, Figure 2 The SSB shown is the SSB sent by the neighboring cell.

[0121] In one implementation, the serving cell may configure a measurement GAP for the terminal device based on the SMTC window configuration and SSB configuration of the neighboring cell, and the duration of the measurement GAP may be greater than or equal to the duration of the SMTC window of the neighboring cell, so that the terminal device measures the SSB sent by the neighboring cell within the measurement GAP. It should be noted that the SMTC window configuration of the neighboring cell may be the same as or different from the SMTC window configuration of the serving cell, and this is not limited in the embodiments of the present application. For example, the duration of the SMTC window of the serving cell may be the same as or different from the duration of the SMTC window of the neighboring cell.

[0122] (5) Discontinuous Reception (DRX), Connected mode DRX (CDRX)

[0123] DRX allows the terminal device to periodically enter a sleep state at certain times and not monitor the Physical Downlink Control Channel (PDCCH). When monitoring is required, the terminal device wakes up from the sleep state to monitor and receive the PDCCH.

[0124] For example, a DRX cycle is as follows: Figure 4 As shown. Among them, a DRX cycle includes wake-up time and sleep time. The wake-up time refers to the period during which the duration timer (On DurationTimer) is running, that is, the period during which the On DurationTimer has not timed out. During the wake-up time, the terminal device monitors and receives PDCCH. When the On DurationTimer times out and the terminal device does not receive the PDCCH, the terminal device enters the sleep state, and the terminal device does not monitor the PDCCH during the sleep time. During the wake-up time, when the terminal device receives the PDCCH, the terminal device starts the drx inactivity timer (drx-InactivityTimer) and monitors the PDCCH while the drx-InactivityTimer is running. Optionally, when the drx-InactivityTimer times out, the terminal device can enter the sleep state.

[0125] CDRX configures the DRX cycle for terminal devices in connected state.

[0126] It should be noted that the wake-up time may include one or more SMTC windows, and the wake-up time may include one or more measurement GAPs.

[0127] The above is a brief introduction to some of the concepts or technologies involved in the embodiments of this application.

[0128] Multimedia service data is characterized by its large data volume, which means that access network equipment can only dispatch a small number of terminal devices to transmit multimedia service data, resulting in limited system capacity. For example, an access network device can dispatch a maximum of 10 terminal devices within its coverage area to support XR services. In other words, the system can accommodate a maximum of 10 terminal devices running XR services. Therefore, how to support more terminal devices to transmit XR service data is a pressing technical challenge.

[0129] In view of this, an embodiment of the present application provides a communication method and a communication device, which uses the measurement time period originally used for measurement (such as same-frequency measurement, different-frequency measurement, and different-system measurement) to transmit scheduling information, thereby helping to improve system capacity and thus helping to support more terminal devices to transmit XR business data in the XR scenario.

[0130] Among them, the measurement time period may include an SMTC window and / or a measurement GAP. It can be understood that before adopting the communication method provided in the embodiment of the present application, within the SMTC window, the access network device will not perform uplink scheduling or downlink scheduling on the terminal device. Accordingly, the terminal device does not need to monitor scheduling information and will not receive scheduling information. Within the measurement GAP, the access network device will not perform uplink scheduling or downlink scheduling on the terminal device. Accordingly, the terminal device does not need to monitor scheduling information and will not receive scheduling information. However, the embodiment of the present application utilizes the SMTC window and / or measurement GAP to transmit scheduling information. The terminal device can monitor scheduling information in the SMTC window and / or measurement GAP. Further, the terminal device can transmit uplink and downlink channels or uplink and downlink signals based on the received scheduling information. The uplink and downlink channels and uplink and downlink signals can carry uplink and downlink multimedia service data, thereby improving the system capacity.

[0131] It should be noted that the embodiments of the present application can be applied not only in multimedia service scenarios, but also in other scenarios that require improving system capacity.

[0132] The following is based on Figure 1 The system architecture shown describes in detail the communication method provided in the embodiment of the present application.

[0133] The following examples (as described below) Figure 5 The terminal device (such as the first terminal device) in the corresponding embodiment can be Figure 1 The terminal device in the network architecture shown in the figure, the functions performed by the terminal device in this embodiment can also be performed by a device in the terminal device (for example, a chip, or a chip system, or a circuit). The access network device in the following embodiment can be Figure 1 The access network device in the network architecture shown, the functions performed by the access network device in this embodiment can also be performed by a device in the access network device (for example, a chip, or a chip system, or a circuit). The embodiments of this application are described here in a unified manner and will not be repeated later.

[0134] See Figure 5 , is a flow chart of a communication method provided in an embodiment of the present application, which may include but is not limited to the following steps:

[0135] 501. An access network device sends a first DCI. The first DCI includes an indication field for at least one terminal device, the at least one terminal device including the first terminal device. The indication field includes a first indication field for the first terminal device, the first indication field carries first indication information, and the first indication information instructs the first terminal device to monitor scheduling information during a first measurement time period within a first CDRX cycle. The scheduling information is used to schedule uplink and downlink channels or uplink and downlink signals. Accordingly, the at least one terminal device receives the first DCI.

[0136] The first downlink control information (Downlink Control Information, DCI) may be carried in a PDCCH, and the access network device may send a PDCCH, where the PDCCH carries the first DCI.

[0137] The first DCI includes an indication field for at least one terminal device, that is, for different terminal devices, the first DCI has a corresponding indication field. In the embodiment of the present application, the at least one terminal device includes a first terminal device as an example, and the first DCI includes a first indication field for the first terminal device. In a possible implementation, the at least one terminal device may include a first terminal device and a second terminal device, and the first DCI may include a first indication field and a second indication field, wherein the first indication field is an indication field for the first terminal device, and the second indication field is an indication field for the second terminal device. The indication field for each terminal device carries indication information for each terminal device. For example, the first indication field can carry indication information for the first terminal device (including one or more of the first indication information, the second indication information, the third indication information, and the fourth indication information mentioned below), and the second indication field can carry indication information for the second terminal device. The relevant contents of the first indication information, the second indication information, the third indication information, and the fourth indication information for the second terminal device can be referred to respectively below. The description of the first indication information, the second indication information, the third indication information, and the fourth indication information for the first terminal device is provided below.

[0138] The first indication information for each terminal device can indicate the behavior of each terminal device within the measurement time period. Taking a terminal device (such as the first terminal device) as an example, the first indication information for the first terminal device can indicate the behavior of the first terminal device within the first measurement time period in the first CDRX cycle. Exemplarily, the behavior of the first terminal device within the first measurement time period indicated by the first indication information may include: the first terminal device listens to the scheduling information within the first measurement time period, or the first terminal device skips the measurement within the first measurement time period. The first terminal device skipping the measurement within the first measurement time period indicates that the first terminal device does not perform the measurement within the first measurement time period. Optionally, if the first indication information for the first terminal device does not indicate that the first terminal device listens to the scheduling information within any measurement time period in the first CDRX cycle, then the first terminal device may perform the measurement within each measurement time period in the first CDRX cycle.

[0139] Exemplarily, take the example of a first DCI including an indication field for a first terminal device (i.e., a first indication field) and an indication field for a second terminal device (i.e., a second indication field), wherein the first indication field carries first indication information a, and the first indication information a indicates the behavior of the first terminal device within the first measurement time period a within the first CDRX cycle a; the second indication field carries first indication information b, and the first indication information b indicates the behavior of the second terminal device within the first measurement time period b within the first CDRX cycle b. For the first terminal device, after monitoring and receiving the PDCCH, the first terminal device can obtain the first DCI from the PDCCH, and parse the first indication field in the first DCI to obtain the first indication information a. Further, the first terminal device monitors the scheduling information within the first measurement time period a based on the information obtained by the parsing. For the second terminal device, after monitoring and receiving the PDCCH, the second terminal device can obtain the first DCI from the PDCCH, and parse the second indication field in the first DCI to obtain the first indication information b. Further, the second terminal device monitors the scheduling information within the first measurement time period b based on the information obtained by the parsing. The first measurement time period a and the first measurement time period b may partially overlap, completely overlap, or not overlap at all.

[0140] The CDRX cycle in the embodiment of the present application (such as the first CDRX cycle) may include at least one measurement time period, and the measurement time period in the first CDRX cycle (such as the first measurement time period, the second measurement time period mentioned later) may include an SMTC window and / or a measurement GAP. In other words, the CDRX cycle in the embodiment of the present application (such as the first CDRX cycle) may include at least one SMTC window and / or at least one measurement GAP.

[0141] The measurement time period in the first CDRX cycle was originally used for measurement. Specifically, the first terminal device could originally measure the SSB from the serving cell within the SMTC window, and since the access network device will not perform uplink scheduling or downlink scheduling on the first terminal device within the SMTC window, accordingly, the first terminal device does not need to monitor the scheduling information within the SMTC window. The first terminal device could originally measure the SSB from the neighboring cell within the SMTC window within the measurement GAP, and since the access network device will not perform uplink scheduling or downlink scheduling on the first terminal device within the measurement GAP, accordingly, the first terminal device does not need to monitor the scheduling information within the measurement GAP. That is to say, before adopting the communication method provided in the embodiment of the present application, the first terminal device does not monitor the scheduling information within the SMTC window or the measurement GAP.

[0142] When adopting the communication method provided in the embodiment of the present application, the first terminal device can monitor the scheduling information within the first measurement time period within the first CDRX cycle. The scheduling information can be used to schedule uplink and downlink channels or uplink and downlink signals. Furthermore, after receiving the scheduling information, the first terminal device can transmit uplink and downlink channels or uplink and downlink signals based on the scheduling information, wherein the uplink and downlink channels or uplink and downlink signals can carry uplink and downlink multimedia service data, which is conducive to improving the system capacity, and thus is conducive to supporting more terminal devices to transmit multimedia service data in multimedia service scenarios.

[0143] The CDRX cycle occurs periodically, and the first CDRX cycle may include one or more CDRX cycles encountered by the first terminal device after receiving the first DCI, and the moment when the first terminal device receives the first DCI is earlier than or equal to the start moment of the first CDRX cycle. For example, the first CDRX cycle is the first CDRX cycle encountered by the first terminal device after receiving the first DCI. In this case, the first CDRX cycle includes one CDRX cycle. For another example, the first CDRX cycle may include multiple consecutive CDRX cycles encountered by the first terminal device after receiving the first DCI until the first terminal device receives the second DCI. The second DCI includes an indication field for the first terminal device, and the indication field for the first terminal device in the second DCI carries indication information for the first terminal device, which may indicate the behavior of the first terminal device within the measurement time period of the second CDRX cycle. The second CDRX cycle may include one or more CDRX cycles encountered by the first terminal device after receiving the second DCI, and the moment when the first terminal device receives the second DCI is earlier than or equal to the start moment of the second CDRX cycle.

[0144] Optionally, for each CDRX cycle, the access network device can send a DCI to indicate the behavior of the first terminal device within the measurement time period within the CDRX cycle. Specifically, the access network device sends multiple DCIs, the sending interval between two adjacent DCIs in the multiple DCIs is the first duration, and the first DCI is one DCI in the multiple DCIs. Correspondingly, the first terminal device monitors multiple DCIs, and the listening interval between two adjacent DCIs in the multiple DCIs is the first duration. Among them, each DCI in the multiple DCIs can respectively indicate the behavior of the first terminal device in the measurement time period in different CDRX cycles. The multiple DCIs can be associated with multiple CDRX cycles, one DCI in the multiple DCIs can be associated with at least one CDRX cycle in the multiple CDRX cycles, and the first DCI is associated with the first CDRX cycle in the multiple CDRX cycles. For example, a schematic diagram of the access network device periodically sending DCI is shown as follows. Figure 6 As shown, Figure 6Taking multiple DCIs including the first DCI and the second DCI as an example, the indication information a (i.e., the first indication information) for the first terminal device in the first DCI indicates that the first terminal device listens to the scheduling information within the measurement time period a within the CDRX cycle 1, and the indication information b for the first terminal device in the second DCI indicates that the first terminal device listens to the scheduling information within the measurement time period b within the CDRX cycle 2. Figure 6 In the example, the first DCI is associated with CDRX cycle 1, and the second DCI is associated with CDRX cycle 2. Figure 6 In the example, measurement period a is a portion of the wake-up time of CDRX cycle 1, and measurement period b is a portion of the wake-up time of CDRX cycle 2. In other possible implementations, measurement period a may be the entire wake-up time of CDRX cycle 1, and measurement period b may be the entire wake-up time of CDRX cycle 2. Optionally, the first duration may be the same as the duration of the CDRX cycle.

[0145] Optionally, if the access network device sends SSB normally in each measurement time period in the first CDRX cycle, then the access network device may not send the first DCI associated with the first CDRX cycle before the start time of the first CDRX cycle. For the first terminal device, if the first terminal device does not receive the first DCI associated with the first CDRX cycle before reaching the start time of the first CDRX cycle, then the first terminal device can determine that SSB is sent normally in each measurement time period in the first CDRX cycle, that is, the first terminal device measures SSB normally in each measurement time period in the first CDRX cycle.

[0146] Optionally, the multiple DCIs sent by the access network device can all be of group DCI type. Group DCI can indicate at least one terminal device, which helps further improve system capacity. Optionally, the multiple DCIs sent by the access network device can all be DCI2_6. DCI2_6 is of group DCI type. In addition to DCI2_6, the multiple DCIs sent by the access network device can also be other types of group DCI.

[0147] It should be noted that before adopting the communication method provided in the embodiment of the present application, DCI2_6 has its own bit field for each terminal device in the at least one terminal device, and the meaning of the bit field is as follows: Taking the at least one terminal device including terminal device a and terminal device b as an example, the structural diagram of DCI2_6 can be as follows: Figure 7 shown. Figure 7In the DCI2_6, DCI2_6 includes indication field 1 for terminal device a, indication field 2 for terminal device b and other indication fields. Taking indication field 1 as an example, indication field 1 may include 1+N bits, wherein the first bit in indication field 1 indicates whether terminal device a starts On DurationTimer. If the first bit indicates that terminal device a starts On DurationTimer, then terminal device a can monitor PDCCH during the operation of On DurationTimer. If the first bit indicates that terminal device a does not start On DurationTimer, then terminal device a can remain in sleep state. In this case, terminal device a does not monitor PDCCH. The N bits can indicate Scell dormancy, and the value of N can be 0 to 5. Figure 7 A square in the grid can represent a bit. Figure 7 Take N=2 as an example, Figure 7 The number of bits in the bit field for different terminal devices is 3 for example. In other implementations, it can also be other numbers. Figure 7 In addition to the indication field 1 and the indication field 2, the other indication fields include 2 bits for example. In other embodiments, they can also be other numbers. For the description of the indication field 2, please refer to the description of the indication field 1, and will not be repeated here.

[0148] In the embodiment of the present application, the meaning of the indication field for at least one terminal device in DCI2_6 can be re-modified. For example, the meaning of the indication field for at least one terminal device included in the original DCI2_6 can be modified to indicate the behavior of at least one terminal device within the measurement time period within the CDRX cycle. Figure 7 The indication field 1 in the CDRX cycle 1 may be used to indicate the behavior of the terminal device a during the measurement period within the CDRX cycle 1. Figure 7 Indication field 2 in may be used to indicate the behavior of terminal device b during the measurement period within CDRX cycle 2.

[0149] After the first terminal device receives the first DCI, the first terminal device may monitor scheduling information within a first measurement time period. Further, after receiving the scheduling information, the first terminal device may transmit (send and / or receive) uplink and downlink channels or uplink and downlink signals based on the scheduling information. The uplink and downlink channels or uplink and downlink signals may carry uplink and downlink multimedia service data. The scheduling information may be carried in the PDCCH.

[0150] In an embodiment of the present application, by using the measurement time period originally used for measurement to transmit scheduling information, it is beneficial to improve the system capacity, thereby facilitating the support of more terminal devices to transmit multimedia service data (such as XR service data) in multimedia service scenarios.

[0151] In one implementation, the first indication information may be implemented as follows:

[0152] The first indication information is carried by the first bit in the first indication field, and the value of the first bit is the first value. The first indication information also indicates that the first terminal device monitors the scheduling information in part or all of the measurement time periods within the first CDRX cycle (or indicates that scheduling information is transmitted in part or all of the measurement time periods within the first CDRX cycle), and the part of the measurement time periods includes the first measurement time period; and / or, the value of the first bit is other values other than the first value. The first indication information also indicates that the first terminal device does not monitor the scheduling information in all measurement time periods within the first CDRX cycle, or the first indication information also indicates that scheduling information is not transmitted in all measurement time periods within the first CDRX cycle, or the first indication information also indicates that measurements are performed normally in all measurement time periods within the first CDRX cycle. The value of the first value can be 1 or 0. The first bit can include at least one bit.

[0153] Taking the case where the first bit includes one bit and the first value is 1 as an example, in one implementation, when the value of the first bit is 1, the first indication information can indicate that the first terminal device monitors the scheduling information in all measurement time periods within the first CDRX cycle (or indicates that scheduling information is transmitted in all measurement time periods within the first CDRX cycle). In another implementation, when the value of the first bit is 1, the first indication information can indicate that the first terminal device monitors the scheduling information in part of the measurement time periods within the first CDRX cycle (or indicates that scheduling information is transmitted in part of the measurement time periods within the first CDRX cycle). Optionally, the first indication field also carries second indication information, and the second indication information can further indicate in which measurement time period or time periods within the first CDRX cycle the first terminal device monitors the scheduling information. For details about the content of the second indication information, please refer to the following text.

[0154] When the value of the first bit is 0, the first indication information may indicate that the first terminal device does not monitor scheduling information during all measurement time periods within the first CDRX cycle, or in other words, indicates that scheduling information is not transmitted during all measurement time periods within the first CDRX cycle, or in other words, indicates that measurements are performed normally during all measurement time periods within the first CDRX cycle. Furthermore, the first terminal device may perform measurements in each measurement time period within the first CDRX cycle.

[0155] Optionally, the first bit may be the first bit in the first indication field. When the first DCI is DCI2_6, the first bit may be the first bit in the bit field for the first terminal device in DCI2_6.

[0156] It should be noted that, for a measurement time period, the transmission of scheduling information within the measurement time period may mean that scheduling information is transmitted in part or all of the time units within the measurement time period, the non-transmission of scheduling information within the measurement time period may mean that scheduling information is not transmitted in all time units within the measurement time period, and the normal execution of measurement within the measurement time period may mean that measurement is performed normally in all time units within the measurement time period. The time unit may be a frame, a subframe, a millisecond (ms), half a millisecond, a slot, a mini slot, a symbol, or a transmission time interval (TTI), etc., and the embodiments of the present application are not limited thereto.

[0157] The above describes how first indication information can be used to indicate whether a measurement time period for transmission scheduling information exists within a first CDRX cycle. Next, when the first indication information indicates that a measurement time period for transmission scheduling information exists within the first CDRX cycle, second indication information can be used to indicate which specific measurement time period or time periods within the first CDRX cycle are to transmit scheduling information.

[0158] In one implementation, the first CDRX cycle may include at least one measurement time period (hereinafter referred to as Z measurement time periods, where Z is a positive integer), and the first indication field may also carry second indication information, and the second indication information may indicate whether the first terminal device monitors scheduling information in each measurement time period in the Z measurement time periods (or indicates whether scheduling information is transmitted in each measurement time period in the Z measurement time periods). In other words, the second indication information may indicate in which measurement time period or time periods of the Z measurement time periods the scheduling information is transmitted, so that the first terminal device monitors the scheduling information in these measurement time periods, and when monitoring and receiving the scheduling information, transmits uplink and downlink channels or uplink and downlink signals based on the scheduling information, which is conducive to improving system capacity, thereby supporting more terminal devices to transmit multimedia service data (such as XR service data) in multimedia service scenarios.

[0159] The Z measurement time periods may be all or part of the measurement time periods in the first CDRX cycle.

[0160] Optionally, when the first indication information instructs the first terminal device to monitor scheduling information within part of the measurement time period within the first CDRX cycle, the first terminal device may further obtain, based on the second indication information, which measurement time period or time periods within the first CDRX cycle to monitor scheduling information. It will be understood that if the second indication information instructs the first terminal device to monitor scheduling information within the first measurement time period of Z measurement time periods (that is, the first measurement time period is the first measurement time period), for other measurement time periods in the Z measurement time periods except the first measurement time period, the first terminal device may perform measurements within these measurement time periods.

[0161] Optionally, when the first indication information indicates that the first terminal device does not monitor scheduling information during all measurement time periods within the first CDRX cycle (or indicates that scheduling information is not transmitted during all measurement time periods within the first CDRX cycle), the first terminal device may not read the second indication information.

[0162] In one implementation, the second indication information may be implemented as follows:

[0163] Method 1: The second indication information may be carried by at least one second bit in the first indication field, wherein the value of one second bit in the at least one second bit is used to indicate whether the first terminal device monitors scheduling information in one of the Z measurement time periods (or indicates whether scheduling information is transmitted in one of the Z measurement time periods). The number of second bits may be Z, with the Z second bits corresponding one-to-one to the Z measurement time periods. The value of the second bit may be the second value or the third value. Taking Z=2 as an example, the Z measurement time periods in the first CDRX cycle include the first measurement time period and the second measurement time period. The second indication information is carried by second bit a and second bit b, wherein the first measurement time period corresponds to second bit a, and the second measurement time period corresponds to second bit b. If, among the Z second bits, the value of the second bit corresponding to the first measurement time period (i.e., second bit a) is the second value, and the value of the second bit corresponding to the second measurement time period (i.e., bit b) is the third value, then the second indication information may instruct the first terminal device to monitor scheduling information in the first measurement time period and not to monitor scheduling information in the second measurement time period. In other words, the second indication information indicates that the scheduling information is transmitted during the first measurement time period, and the scheduling information is not transmitted during the second measurement time period. Optionally, the first terminal device can perform measurements during the second measurement time period. In this way, both scheduling information can be transmitted and measurements can be performed during the first CDRX cycle, which is beneficial to improving the system capacity while ensuring the communication quality of the first terminal device. The second value and the third value are 1 and 0, respectively, or the second value and the third value are 0 and 1, respectively. Method 1 can be understood as the second indication information indicating whether the first terminal device monitors the scheduling information during each measurement time period in Z measurement time periods in the form of a bitmap, and the bitmap includes Z second bits.

[0164] Method 2: The second indication information includes an index of a first measurement pattern in at least one measurement pattern (hereinafter referred to as a first measurement pattern set, the first measurement pattern set including at least one measurement pattern). Each measurement pattern in the first measurement pattern set can be used to indicate whether the first terminal device monitors scheduling information in each measurement time period in Z measurement time periods (or to indicate whether scheduling information is transmitted in each measurement time period in the Z measurement time periods). The first measurement pattern is a measurement pattern in the first measurement pattern set. That is, the second indication information specifically indicates whether the first terminal device monitors scheduling information in each measurement time period in the Z measurement time periods through the first measurement pattern.

[0165] For example, taking Z=3, the Z measurement time periods are measurement time period a, measurement time period b, and measurement time period c, the first measurement pattern set includes 8 measurement patterns, and the indexes of the 8 measurement patterns are 0-7, the content indicated by each measurement pattern in the first measurement pattern set can be seen in Table 1. In Table 1, √ can indicate that scheduling information is transmitted in the corresponding measurement time period, and × can indicate that scheduling information is not transmitted in the corresponding measurement time period.

[0166] Table 1

[0167]

[0168] Exemplarily, if the index of the first measurement pattern included in the second indication information is 1, referring to Table 1, the second indication information can instruct the first terminal device to monitor the scheduling information within the measurement time period a, and can also instruct the first terminal device not to monitor the scheduling information within the measurement time period b and the measurement time period c. Optionally, the second indication information can carry the index of the first measurement pattern through at least one bit. For example, for the 8 measurement patterns shown in Table 1, the second indication information can carry the index of the first measurement pattern through 3 bits.

[0169] Optionally, the access network device may send configuration information, which may be used to configure the first measurement pattern set. Accordingly, the first terminal device may receive the configuration information and, in combination with the first measurement pattern set configured in the configuration information and the index of the first measurement pattern in the second indication information, determine in which measurement time period or time periods of the Z measurement time periods the first measurement pattern specifically instructs the first terminal device to monitor scheduling information.

[0170] Optionally, the configuration information may be carried in Radio Resource Control (RRC).

[0171] It should be noted that, when the first CDRX cycle includes only one measurement time period (the measurement time period being the first measurement time period), the first indication information may indicate whether scheduling information is transmitted within the first measurement time period, or the first indication information and the second indication information may jointly indicate whether scheduling information is transmitted within the first measurement time period. When the first CDRX cycle includes at least two measurement time periods (one of which is the first measurement time period), the first indication information and the second indication information may jointly indicate whether scheduling information is transmitted within each measurement time period in the first CDRX cycle.

[0172] Regardless of whether the access network device instructs the first measurement time period to transmit scheduling information through the first indication information, or instructs the first measurement time period to transmit scheduling information through a combination of the first indication information and the second indication information, the transmission of scheduling information during the first measurement time period may indicate that the scheduling information is transmitted during some or all time units within the first measurement time period. Furthermore, the access network device may further indicate, through third indication information, which specific time unit or time units within the first measurement time period are to transmit scheduling information.

[0173] In one implementation, the first bit field may also carry third indication information, where the third indication information indicates that the first terminal device listens to scheduling information within the first time within the first measurement time period (or indicates that scheduling information is transmitted within the first time within the first measurement time period), wherein the unit of the first time includes one or more of milliseconds, time slots, or symbols.

[0174] Among them, the unit of the first time includes milliseconds, which can be understood as: according to milliseconds (ms) or half a millisecond (0.5ms) as the indication granularity, the third indication information is used to indicate which milliseconds (or half a millisecond) the first terminal device should listen to the scheduling information within within the first measurement time period (or, to indicate which milliseconds (or half a millisecond) within the first measurement time period the scheduling information is transmitted). The embodiment of the present application takes the third indication information as an example to indicate which milliseconds (or half a millisecond) the first terminal device should listen to the scheduling information within within the first measurement time period. These milliseconds can be called the first millisecond.

[0175] The first time unit includes time slots, which can be understood as: using time slots as the indication granularity, the third indication information indicates which time slots the first terminal device should listen to scheduling information in within the first measurement time period (or, indicates which time slots the first measurement time period should transmit scheduling information), and these time slots are called first time slots.

[0176] The unit of the first time includes symbols, which can be understood as: according to the symbol as the indication granularity, the third indication information indicates which symbol or symbols in the first measurement time period the first terminal device listens to the scheduling information (or, indicates which symbol or symbols in the first measurement time period the scheduling information is transmitted), and these symbols are called first symbols.

[0177] It can be understood that the first time may include one or more of the following: at least half a first millisecond, at least one first time slot, and at least one first symbol.

[0178] Optionally, the third indication information may further indicate that the scheduling information is transmitted within the first millisecond, based on the fact that the scheduling information is transmitted within the first time slot within the first millisecond. This approach may be understood as the third indication information being notified in two levels, with the first level notifying the first millisecond and the second level notifying the first time slot. One millisecond may include at least one time slot. For example, taking a subcarrier spacing of 30 kHz as an example, the time slot length is 0.5 ms. In this case, 1 ms may include 2 time slots.

[0179] Optionally, the third indication information, in addition to indicating that scheduling information is transmitted in the first time slot, may further indicate that scheduling information is transmitted in the first symbol in the first time slot. This approach can be understood as the third indication information being notified in two levels: the first level notifies the first time slot, and the second level notifies the first symbol.

[0180] Optionally, the third indication information indicates that scheduling information is transmitted in the first time slot within the first millisecond, and can further indicate that scheduling information is transmitted in the first symbol within the first time slot. This method can be understood as the third indication information being divided into three levels of notification, the first level notifying the first millisecond, the second level notifying the first time slot, and the third level notifying the first symbol.

[0181] Based on the third indication information, the first terminal device can monitor the scheduling information within the first millisecond, the first time slot and / or the first symbol, wherein the number of the first millisecond is at least one, the number of the first time slot is at least one, and the number of the first symbol is at least one. When the first terminal device monitors and receives the scheduling information, it transmits uplink and downlink channels or uplink and downlink signals based on the scheduling information, which is conducive to improving the system capacity, thereby supporting more terminal devices to transmit multimedia service data (such as XR service data) in multimedia service scenarios.

[0182] The first measurement period may include multiple milliseconds, and the first millisecond may include all or part of the milliseconds in the first measurement period. The first measurement period may include multiple time slots, and the first time slot may include all or part of the time slots in the first measurement period. The first millisecond may include multiple time slots, and the first time slot may include all or part of the time slots in the first millisecond. The first time slot may include multiple symbols, and the first symbol may include all or part of the symbols in the first time slot. The symbols in the embodiments of the present application may refer to OFDM symbols.

[0183] The first measurement time period may include multiple milliseconds. For milliseconds other than the first millisecond in the first measurement time period (e.g., referred to as second milliseconds), the first terminal device may perform measurements within the second milliseconds, and the number of second milliseconds may be at least one. The first measurement time period may include multiple time slots. For time slots other than the first time slot in the first measurement time period (e.g., referred to as second time slots), the first terminal device may perform measurements within the second time slots, and the number of second time slots may be at least one. The first millisecond may include multiple time slots. For time slots other than the first time slot in the first millisecond (e.g., referred to as third time slots), the first terminal device may perform measurements within the third time slots, and the number of third time slots may be at least one. The first time slot may include multiple symbols. For symbols other than the first symbol in the first time slot (e.g., referred to as second symbols), the first terminal device may perform measurements within the second symbol.

[0184] In one implementation, the third indication information may be implemented as follows:

[0185] Mode 3: The third indication information is carried by one or more of the following in the first indication field: at least one third bit, at least one fourth bit, and at least one fifth bit, wherein the value of one third bit in the at least one third bit is used to indicate that the first terminal device listens to the scheduling information within half a millisecond or one millisecond in the first measurement time period (or, indicates that scheduling information is transmitted within half a millisecond or one millisecond in the first measurement time period); the value of one fourth bit in the at least one fourth bit is used to indicate that the first terminal device listens to the scheduling information within a time slot in the first measurement time period (or indicates that scheduling information is transmitted within a time slot in the first measurement time period), and the value of one fifth bit in the at least one fifth bit is used to indicate that the first terminal device listens to the scheduling information within a symbol in the first measurement time period (or indicates that scheduling information is transmitted within a symbol in the first measurement time period). The values of the third bit, the fourth bit, and the fifth bit can all be 1 or 0.

[0186] Taking the example of the first measurement time period including A milliseconds (A is an integer greater than or equal to 2) with milliseconds as the indication granularity, the number of third bits can be A, and A third bits correspond one to one with A milliseconds. The value of the third bit can be 0 or 1. Taking the example of the first measurement time period including an SMTC window with a duration of 5 milliseconds (ms) as the example, the number of third bits can be 5, wherein the 1st bit, 2nd bit, 3rd bit, 4th bit, and 5th bit of the 5 third bits correspond to the 1st millisecond, 2nd millisecond, 3rd millisecond, 4th millisecond, and 5th millisecond in 5 milliseconds respectively. Assuming that the value of the third bit is 1, it means that scheduling information is transmitted in the millisecond corresponding to the third bit. When the values of the 5 third bits are 11110, the third indication information instructs the first terminal device to listen for scheduling information in the 1st to 4th milliseconds in the SMTC window, that is, the first millisecond includes the first 4 milliseconds in the SMTC window. Optionally, the first terminal device may perform measurement within the 5th millisecond within the SMTC window.

[0187] For another example, if the first measurement time period includes a measurement GAP, and the duration of the measurement GAP is 6 milliseconds (ms), the number of third bits can be 6, wherein the 1st bit, 2nd bit, 3rd bit, 4th bit, 5th bit, and 6th bit of the 6 third bits correspond to the 1st millisecond, 2nd millisecond, 3rd millisecond, 4th millisecond, 5th millisecond, and 6th millisecond within the 6 milliseconds, respectively. Assuming that the value of the third bit is 1, it means that scheduling information is transmitted within the millisecond corresponding to the third bit. When the values of the 6 third bits are 111110, the third indication information instructs the first terminal device to listen for scheduling information within the 1st to 5th milliseconds within the measurement GAP. That is, the first millisecond indicated by the third indication information can include the first 5 milliseconds within the measurement GAP.

[0188] Taking the example that the first measurement time period includes B time slots (B is an integer greater than or equal to 2), the number of fourth bits can be B, and the B fourth bits correspond one-to-one to the B time slots. The value of the fourth bit can be 0 or 1. Taking the example that the first measurement time period includes an SMTC window, and SCS=30Khz, the duration of the SMTC window is 5ms, and the SMTC window includes 10 time slots, the number of fourth bits can be 10, wherein the 10 time slots are time slots 0 to time slot 9, and the 1st bit, 2nd bit, 3rd bit, 4th bit, 5th bit, 6th bit, 7th bit, 8th bit, 9th bit, and 10th bit of the 10 fourth bits correspond to time slot 0, time slot 1, time slot 2, time slot 3, time slot 4, time slot 5, time slot 6, time slot 7, time slot 8, and time slot 9, respectively. Assuming that the value of the fourth bit is 1, it indicates that scheduling information is transmitted in the time slot corresponding to the fourth bit. When the value of the fourth bit is 1111000000, the third indication information instructs the first terminal device to monitor scheduling information in time slots 0 to 3 within the SMTC window, that is, the first time slot includes the four time slots 0 to 3. Optionally, the first terminal device can perform measurements in time slots 4 to 9.

[0189] Taking the first time slot including C symbols (C is an integer greater than or equal to 2) as an example, the number of fifth bits can be C, and the C fifth bits correspond one-to-one to the C time slots. The value of the fifth bit can be 0 or 1. Taking the first time slot including 14 symbols, the number of fifth bits can be 14, where the 14 symbols are symbol 0 to symbol 13, and the 1st bit, 2nd bit, 3rd bit, 4th bit, 5th bit, 6th bit, 7th bit, 8th bit, 9th bit, 10th bit, 11th bit, 12th bit, 13th bit, and 14th bit of the 14 fifth bits correspond to symbol 0, symbol 1, symbol 2, symbol 3, symbol 4, symbol 5, symbol 6, symbol 7, symbol 8, symbol 9, symbol 10, symbol 11, symbol 12, and symbol 13, respectively. Assuming that the value of the fifth bit is 1, it indicates that scheduling information is transmitted in the symbol corresponding to the fifth bit. When the values of the 14 fifth bits are 00111100111100, the fourth indication information instructs the first terminal device to monitor scheduling information in the eight symbols from symbol 2 to symbol 5 and symbol 8 to symbol 11 in the SMTC window, that is, the first symbol includes symbols 2 to symbol 5 and symbols 8 to symbol 11. Optionally, the first terminal device can perform measurements in symbols 0 to symbol 1, symbols 6 to symbol 7, and symbols 12 to symbol 13.

[0190] Mode 4: The third indication information includes one or more of the following: an index of the second measurement pattern, an index of the third measurement pattern, and an index of the fourth measurement pattern. The second measurement pattern is a measurement pattern in the second measurement pattern set, the third measurement pattern is a measurement pattern in the third measurement pattern set, and the fourth measurement pattern is a measurement pattern in the fourth measurement pattern set. Each measurement pattern in the second measurement pattern set can be used to indicate whether scheduling information is transmitted in each half millisecond or each millisecond in the first measurement time period. That is, the third indication information can indicate whether the first terminal device monitors scheduling information in each half millisecond or each millisecond in the first measurement time period through the second measurement pattern. Each measurement pattern in the third measurement pattern set can be used to indicate whether scheduling information is transmitted in each time slot in the first measurement time period. That is, the third indication information can indicate whether the first terminal device monitors scheduling information in each time slot in the first measurement time period through the third measurement pattern. Scheduling information is transmitted in the first time slot within the first measurement time period, and each measurement pattern in the fourth measurement pattern set can be used to indicate whether scheduling information is transmitted in each symbol in the first time slot. That is, the third indication information can indicate whether the first terminal device monitors scheduling information in each symbol in the first time slot through the fourth measurement pattern.

[0191] For example, taking the example where the first measurement time period includes an SMTC window with a duration of 5 ms, the second measurement pattern set includes 8 measurement patterns, and each measurement pattern in the second measurement pattern set can be used to indicate whether scheduling information is transmitted in each millisecond in the SMTC window, and the indexes of the 8 measurement patterns are 0-7, the content indicated by each measurement pattern in the second measurement pattern set can be seen in Table 2. In Table 2, √ can indicate that scheduling information is transmitted in the corresponding millisecond, and × can indicate that scheduling information is not transmitted in the corresponding millisecond.

[0192] Table 2

[0193]

[0194] Exemplarily, if the index of the second measurement pattern included in the third indication information is 6, referring to Table 2, the third indication information can instruct the first terminal device to listen to the scheduling information within the 1st to 2nd milliseconds (i.e., the first 2 milliseconds) within the SMTC window, and can also instruct the first terminal device not to listen to the scheduling information in the last 3 milliseconds within the SMTC window. Optionally, the third indication information can carry the index of the second measurement pattern through at least one bit. For example, for the 8 measurement patterns shown in Table 2, the third indication information can carry the index of the second measurement pattern through 3 bits.

[0195] For another example, taking the case where the first measurement time period includes an SMTC window, SCS=30 kHz, the duration of the SMTC window is 5 ms, the SMTC window includes 10 time slots, and the third measurement pattern set includes 16 measurement patterns, the 10 time slots are time slot 0 to time slot 9, and the indexes of the 16 measurement patterns are 0 to 15, the content indicated by each measurement pattern in the third measurement pattern set can be seen in Table 3. In Table 3, √ may indicate that scheduling information is transmitted in the corresponding time slot, and × may indicate that scheduling information is not transmitted in the corresponding time slot.

[0196] Table 3

[0197]

[0198] For example, if the index of the third measurement pattern included in the third indication information is 15, as shown in Table 3, the third indication information can instruct the first terminal device to monitor scheduling information in time slots 0 to 3, and can also instruct the first terminal device not to monitor scheduling information in time slots 4 to 9. Optionally, the third indication information can carry the index of the third measurement pattern via at least one bit. For example, for the 16 measurement patterns shown in Table 3, the third indication information can carry the index of the third measurement pattern via 4 bits.

[0199] For another example, taking the case where the first time slot includes time slot 0, time slot 0 includes 14 symbols, the fourth measurement pattern set includes 4 measurement patterns, the 14 symbols are symbol 0 to symbol 13, and the indexes of the 4 measurement patterns are 0 to 3, the contents indicated by each measurement pattern in the fourth measurement pattern set can be seen in Table 4. In Table 4, √ may indicate that scheduling information is transmitted in the corresponding symbol, and × may indicate that scheduling information is not transmitted in the corresponding symbol.

[0200] Table 4

[0201]

[0202]

[0203] Exemplarily, if the index of the fourth measurement pattern included in the third indication information is 3, referring to Table 4, the third indication information can instruct the first terminal device to monitor the scheduling information at symbols 2-5 and 8-11, and can also instruct the first terminal device not to monitor the scheduling information at symbols 0-1, 6-7, and 12-13. Optionally, the third indication information can carry the index of the fourth measurement pattern through at least one bit. For example, for the four measurement patterns shown in Table 4, the third indication information can carry the index of the fourth measurement pattern through two bits.

[0204] Optionally, in addition to being used to configure the first measurement pattern set, the aforementioned configuration information can also be used to configure one or more of the second measurement pattern set, the third measurement pattern set, and the fourth measurement pattern set. Accordingly, the first terminal device, in combination with the measurement pattern set configured by the configuration information (including one or more of the first measurement pattern set, the second measurement pattern set, the third measurement pattern set, and the fourth measurement pattern set), as well as the index of the first measurement pattern, the index of the second measurement pattern, the index of the third measurement pattern, and the index of the fourth measurement pattern, can determine in which measurement time period or time periods in the first CDRX cycle to monitor scheduling information, and in which milliseconds (or half milliseconds) in the measurement time period to monitor scheduling information, and in which time slots in the measurement time period to monitor scheduling information, and in which symbols in the time slot to monitor scheduling information. In this way, more detailed instructions can be provided, which is conducive to saving more resources for scheduling multimedia service data.

[0205] Each measurement time period in the first CDRX cycle (including the first measurement time period) may include a time unit corresponding to at least one SSB (hereinafter referred to as M SSBs, where M is a positive integer), and the M SSBs may include all SSBs in an SS burst set. For example, the frequency point of the cell where the SSB is sent belongs to the Sub3G to Sub6G frequency band. The cell can send up to 8 SSBs in the SMTC window. Figure 2 Taking the first SMTC window shown as an example, the SMTC window includes two time units corresponding to SSBs. When the time unit is a time slot, Figure 2 The time unit corresponding to the first SSB and the time unit corresponding to the second SSB in are both time slot 0. When the time unit is a symbol, Figure 2 The time unit corresponding to the first SSB in may include symbols 2 to 5. Figure 2 The time unit corresponding to the second SSB in may include symbols 8 to 11.

[0206] Next, it is introduced how to indicate through the fourth indication information which SSB or SSBs in the first measurement time period within which the scheduling information is transmitted, in the case where the first indication information indicates that there is a measurement time period (first measurement time period) for transmitting scheduling information in the first CDRX cycle. Furthermore, the first terminal device can listen to the scheduling information in the time units corresponding to these SSBs, and transmit uplink and downlink channels or uplink and downlink signals based on the scheduling information when listening to and receiving the scheduling information. This is conducive to improving the system capacity, thereby supporting more terminal devices to transmit multimedia service data (such as XR service data) in multimedia service scenarios.

[0207] In one implementation, the first measurement time period includes time units corresponding to M SSBs, and the first indication field may further carry fourth indication information. The fourth indication information may instruct the first terminal device to monitor scheduling information within a time unit corresponding to a first SSB among the M SSBs. Further, upon monitoring and receiving the scheduling information, the first terminal device transmits uplink and downlink channels or uplink and downlink signals based on the scheduling information. The number of the first SSBs may be one or more.

[0208] It should be noted that the access network device transmits scheduling information within the time unit corresponding to the first SSB, and the access network device no longer sends the SSB within the time unit corresponding to the first SSB. Accordingly, the first terminal device does not perform measurement within the time unit corresponding to the first SSB, but listens to and receives scheduling information. Optionally, the access network device transmits the second SSB within the time unit corresponding to other SSBs (such as the second SSB) among the M SSBs except the first SSB, and accordingly, the terminal device can measure the second SSB within the time unit corresponding to the second SSB.

[0209] In one implementation, the fourth indication information may include an index of the first SSB. The first terminal device may determine the index of the first symbol of the first SSB based on the index of the first SSB and the aforementioned Case A to Case F. One SSB occupies four symbols. Therefore, the first terminal device may determine the positions of the four symbols of the first SSB based on the index of the first symbol of the first SSB, and then monitor the scheduling information on these four symbols.

[0210] In another implementation, the fourth indication information may include a beam index, and the first terminal device may determine the first SSB based on the beam index and the correspondence between the beam index and the SSB index, where the beam index in the fourth indication information corresponds to the index of the first SSB. One beam index corresponds to one SSB index.

[0211] In one implementation, the fourth indication information may be implemented as follows:

[0212] Mode 5: The fourth indication information is carried by at least one sixth bit in the first indication field, wherein the value of one sixth bit in the at least one sixth bit is used to indicate whether the first terminal device monitors the scheduling information within the time unit corresponding to an SSB in the first measurement time period. The number of sixth bits may be M, and the M sixth bits correspond one-to-one to the M SSBs. The value of the sixth bit may be 0 or 1. Taking M=2 as an example, the M SSBs include SSB-0 and SSB-1, wherein the index of SSB-0 is 0, and the index of SSB-1 is 1. The fourth indication information is carried by the sixth bit a and the sixth bit b, wherein SSB-0 corresponds to the sixth bit a, and SSB-1 corresponds to the sixth bit b. Assuming that the value of the sixth bit is 1, it indicates that scheduling information is transmitted in the time unit corresponding to the SSB corresponding to the sixth bit. If, among the M sixth bits, the value of the sixth bit a corresponding to SSB-0 is 1, and the value of the sixth bit b corresponding to SSB-1 is 0, then it can be indicated that the time unit corresponding to SSB-0 is used to transmit scheduling information, and the time unit corresponding to SSB-1 is used to transmit SSB. That is to say, the fourth indication information instructs the first terminal device to monitor the scheduling information in the time unit corresponding to SSB-0, and can also instruct the first terminal device to measure SSB in the time unit corresponding to SSB-1.

[0213] Method 6: The fourth indication information may include an index of a fifth measurement pattern in at least one measurement pattern (hereinafter referred to as the fifth measurement pattern set, the fifth measurement pattern set including at least one measurement pattern), and each measurement pattern in the fifth measurement pattern set can be used to indicate whether scheduling information is transmitted within the time unit corresponding to each SSB in the M SSBs. The fifth measurement pattern is a measurement pattern in the fifth measurement pattern set, that is, the fourth indication information specifically indicates through the fifth measurement pattern whether the first terminal device monitors the scheduling information within the time unit corresponding to each SSB in the M SSBs.

[0214] For example, taking the case where the first measurement time period includes time units corresponding to 8 SSBs, and the fifth measurement pattern set includes 16 measurement patterns, the 8 SSBs are SSB-0, SSB-1, SSB-2, SSB-3, SSB-4, SSB-5, SSB-6, and SSB-7, where i in SSB-i represents the index of the SSB. Taking the case where the indexes of the 16 measurement patterns are 0-15, the contents indicated by each measurement pattern in the fifth measurement pattern set can be seen in Table 5. In Table 5, √ may indicate that scheduling information is transmitted within the time unit corresponding to the SSB, and × may indicate that scheduling information is not transmitted within the time unit corresponding to the SSB.

[0216]

[0217]

[0218] Exemplarily, if the index of the fifth measurement pattern included in the fourth indication information is 15, referring to Table 5, it can be seen that the fourth indication information can instruct the first terminal device to monitor the scheduling information in the time units corresponding to SSB-0, SSB-1, SSB-2, SSB-3, SSB-4, SSB-5, SSB-6, and SSB-7. Optionally, the fourth indication information can carry the index of the fifth measurement pattern through at least one bit. For example, for the 16 measurement patterns shown in Table 5, the fourth indication information can carry the index of the fifth measurement pattern through 4 bits.

[0219] Optionally, the aforementioned configuration information may be used to configure one or more of the first measurement pattern set, the second measurement pattern set, the third measurement pattern set, the fourth measurement pattern set, and the fifth measurement pattern set.

[0220] Optionally, when the first DCI is DCI2_6, the first indication field may be a bit field for the first terminal device in DCI2_6. Specifically, the first bit in the first indication field may be the first bit in the bit field for the first terminal device in DCI2_6, and other bits in the bit field for the first terminal device in DCI2_6 except the first bit may include: one or more of: at least one second bit, at least one third bit, at least one fourth bit, at least one fifth bit, and at least one sixth bit in the first indication field.

[0221] In one implementation, the first terminal device may send fifth indication information, which may be used to indicate that the first terminal device expects not to perform measurement within one or more measurement time periods within the first CDRX cycle, or in other words, the fifth indication information may be used to indicate that the first terminal device expects to skip measurement within one or more measurement time periods within the first CDRX cycle, or in other words, the fifth indication information may be used to indicate that the first terminal device expects to listen to scheduling information within one or more measurement time periods within the first CDRX cycle, or in other words, the fifth indication information may be used to indicate that the first terminal device expects to perform uplink and downlink data transmission with the access network device within one or more measurement time periods within the first CDRX cycle. Accordingly, the access network device may receive the fifth indication information and, based on the fifth indication information, send the first DCI.

[0222] Optionally, the fifth indication information may be carried in RRC, medium access control-control element (MAC CE) or uplink control information (UCI), wherein RRC may be user equipment assistance information (UE Assistance Information, UAI) or other RRC messages.
