Description

Uplink and downlink resource joint scheduling methods, terminals, network devices, storage media and products Technical Field

[0001] This disclosure relates to the field of communication technology, and in particular to a method for joint scheduling of uplink and downlink resources, as well as terminals, network devices, storage media, and products. Background Technology

[0002] Micro-domain networks are short-range wireless networks that can be deployed in terminals such as production line modules, vehicles, and wearable devices. Micro-domain networks introduce cluster nodes (Headpoints, HPs), which coordinate and manage terminal access, connections, resource allocation, and transmission quality management. Cluster nodes also possess some core network functions, transmitting information with terminals to form a closed-loop transmission system for local services within the micro-domain. Network devices need to allocate uplink and downlink resources to the terminals.

[0003] Currently, uplink and downlink resource allocation generally adopts a licensed scheduling method. That is, for uplink transmission, the terminal sends a scheduling request to the base station, and the base station allocates uplink resources to the terminal so that the terminal can send uplink information to the network device on the allocated uplink resources. For downlink transmission, the network device sends downlink indication information to the terminal in the search space. This downlink indication information is used to instruct the terminal to receive downlink information sent by the network device on downlink resources.

[0004] However, existing authorized scheduling methods result in significant transmission delays and signaling overhead, failing to meet the low-latency transmission requirements in micro-domain networks. Summary of the Invention

[0005] This disclosure is made in view of the above-mentioned problems. This disclosure provides a method for joint scheduling of uplink and downlink resources, as well as terminals, network devices, storage media, and products.

[0008] The network device receives a second instruction message, which instructs the network device to configure periodic first uplink resources and uplink / downlink resource association information for the terminal according to the terminal's service type.

[0009] Based on the association information between the first uplink resource and the uplink and downlink resources, the first downlink resource is determined. The first uplink resource is used to send uplink information, and the first downlink resource is used to listen for downlink information.

[0019] Alternatively, if the first uplink resource and the first downlink resource are in the same subband, and the uplink information transmission is not completed on the first uplink resource in a transmission cycle, then the starting position of the first downlink resource in the time domain is k1 symbols or time slots away from the last symbol or the time slot of the first uplink resource in the transmission cycle in which the uplink information transmission is completed.

[0020] Alternatively, if the first uplink resource and the first downlink resource are different subbands, and the uplink information transmission is completed on the first uplink resource in one transmission cycle, then the starting position of the first downlink resource in the time domain is k2 symbols or time slots away from the last symbol or the time slot of the last symbol of the first uplink resource.

[0021] Alternatively, if the first uplink resource and the first downlink resource are in different subbands, and the uplink information transmission is not completed on the first uplink resource in a transmission cycle, then the starting position of the first downlink resource in the time domain is k2 symbols or time slots away from the last symbol or the time slot of the first uplink resource in the transmission cycle in which the uplink information transmission is completed.

[0022] Optionally, if the first uplink resource and the first downlink resource are different subbands, the following method is also included:

[0028] Optionally, the resource usage priority of the terminal of the first service type is higher than that of the terminal of the second service type.

[0029] Optionally, it also includes:

[0030] The fifth indication information is received. The fifth indication information is sent by the network device in the second search space within the transmission cycle of the first uplink resource when the terminal is of the second service type.

[0047] When the terminal is in the second service type, a fifth indication message is sent in the second search space within the transmission cycle of the first uplink resource. The fifth indication message is used to indicate that the terminal discards the downlink information detected in the first downlink resource in the previous transmission cycle if the first downlink resource in the previous transmission cycle is occupied by other terminals.

[0073] To make the objectives, technical solutions, and advantages of this disclosure more apparent, exemplary embodiments according to this disclosure will now be described in detail with reference to the accompanying drawings. Obviously, the described embodiments are merely some embodiments of this disclosure, and not all embodiments of this disclosure. It should be understood that this disclosure is not limited to the exemplary embodiments described herein.

[0074] The technical solutions of this application embodiment can be applied to various communication systems, such as: wireless local area network (WLAN) communication systems, long term evolution (LTE) systems, LTE frequency division duplex (FDD) systems, LTE time division duplex (TDD) systems, 5th generation (5G) systems or new radio (NR) systems, 6th generation (6G) systems, worldwide interoperability for microwave access (WiMAX) communication systems, or other evolved communication systems, etc.

[0075] The terminal in this application embodiment may also be referred to as: user equipment (UE), mobile station (MS), mobile terminal (MT), access terminal, user unit, user station, mobile station, mobile station, remote station, remote terminal, mobile device, user terminal, terminal, wireless communication equipment, user agent, or user device, etc.

[0076] Examples of terminals include: vehicles, mobile phones, tablets, laptops, PDAs, mobile internet devices (MIDs), wearable devices, virtual reality (VR) devices, augmented reality (AR) devices, wireless terminals in industrial control, wireless terminals in self-driving vehicles, wireless terminals in remote medical surgery, wireless terminals in smart grids, wireless terminals in transportation safety, wireless terminals in smart cities, wireless terminals in smart homes, cellular phones, cordless phones, session initiation protocol (SIP) phones, wireless local loop (WLL) stations, personal digital assistants (PDAs), handheld devices with wireless communication capabilities, computing devices or other processing devices connected to a wireless modem, in-vehicle devices, wearable devices, drones, terminals in 5G networks, or future evolution of public land mobile communication networks. The embodiments of this application do not limit the scope of terminals, etc. in a network (PLMN).

[0077] Furthermore, in this embodiment, the terminal can also be a terminal in an Internet of Things (IoT) system, such as a robotic arm, AGV, or robot on a factory production line. IoT is an important component of future information technology development, and its main technical feature is to connect objects to the network through communication technology, thereby realizing an intelligent network of human-machine interconnection and object-to-object interconnection.

[0078] Furthermore, the network device in this application embodiment can be a device for communicating with a terminal. This network device can also be called an access network device or a wireless access network device. It can be a cluster node (HP), a transmission reception point (TRP), an evolved NodeB (eNB or eNodeB) in an LTE system, a home base station (e.g., home evolved NodeB, or home Node B, HNB), a base band unit (BBU), a wireless controller in a cloud radio access network (CRAN) scenario, or a relay station, access point, vehicle-mounted device, wearable device, and network device in a 5G network or a network device in a future evolved PLMN network, etc. It can be an access point (AP) in a WLAN, a gNB in ​​a new radio (NR) system, a satellite base station in a satellite communication system, or various forms of devices that perform base station functions, etc. This application embodiment is not limited.

[0079] To facilitate understanding of the embodiments of this application, the communication system 100 of the micro-domain network applicable to the embodiments of this application will be described in detail first with reference to FIG1.

[0080] The communication system 100 includes a terminal 101, a cluster node 102, and a base station 103. The terminal 101 can be an example of a robotic arm, AGV, or robot on a factory production line. Sensors can be configured on the terminal 101, which can periodically collect data and report it to the controller, i.e., the cluster node 102. The controller can process the data collected by the sensors and generate action commands. The controller can also send action commands to drivers, which execute the actions. The drivers can be located on the terminal 101. Therefore, there is uplink data transmission between the terminal 101 and the cluster node 102 (e.g., transmission of data collected by sensors), and downlink data transmission between the cluster node 102 and the drivers of the terminal 101 (e.g., transmission of action commands). This involves the scheduling of uplink and downlink resources for the terminal 101, which is typically handled by network devices such as the cluster node 102 or the base station 103.

[0081] However, those skilled in the art have found that for uplink transmission, the terminal sends a scheduling request to the base station, which then allocates uplink resources to the terminal so that the terminal can send uplink information to the network device on the allocated uplink resources. For downlink transmission, the network device sends downlink indication information to the terminal in the search space. This downlink indication information is used to instruct the terminal to receive downlink information sent by the network device on downlink resources. The allocation of uplink and downlink resources depends on the acquisition requests and indications for uplink and downlink resources, respectively, resulting in significant transmission delays and signaling overhead, which cannot meet the low-latency transmission requirements in micro-domain networks.

[0082] In view of this, embodiments of this application provide a method for joint scheduling of uplink and downlink resources, as well as a terminal, network device, storage medium, and product, which is beneficial to improving the allocation efficiency of periodic resources.

[0083] To facilitate a clear description of the technical solutions in the embodiments of this application, the terms "first" and "second" are used in the embodiments of this application to distinguish identical or similar items with essentially the same function and purpose. For example, "first dataset" and "second dataset" are used to distinguish different datasets and do not limit their order. Those skilled in the art will understand that the terms "first" and "second" do not limit the quantity or execution order, and that "first" and "second" do not necessarily imply that they are different.

[0084] It should be noted that, in this application, the words "exemplarily" or "for example" are used to indicate examples, illustrations, or explanations. Any embodiment or design described as "exemplarily" or "for example" in this application should not be construed as being more preferred or advantageous than other embodiments or designs. Specifically, the use of words such as "exemplarily" or "for example" is intended to present the relevant concepts in a specific manner.

[0085] Furthermore, "at least one" refers to one or more, while "more than one" refers to two or more. "And / or" describes the relationship between related objects, indicating that three relationships can exist. For example, A and / or B can mean: A alone, A and B simultaneously, or B alone, where A and B can be singular or plural. The character " / " generally indicates that the preceding and following related objects are in an "or" relationship. "At least one of the following" or similar expressions refer to any combination of these items, including any combination of single or plural items. For example, at least one of a, b, and c can mean: a, or b, or c, or a and b, or a and c, or b and c, or a, b, and c, where a, b, and c can be single or multiple.

[0086] The various embodiments provided in this application will now be described in detail.

[0087] This application describes embodiments using terminals and network devices as examples. It should be understood that the terminal can be replaced with a device or chip capable of performing similar functions. Similarly, the network device can be replaced with a device or chip capable of performing similar functions; the names of these devices are not limited in this application. The relationship between the terminal and the network device can be one-to-one, one-to-many, many-to-one, or many-to-many. The number of terminals or network devices is not excessively limited in this application. The network composed of terminals and network devices can be a micro-domain network.

[0088] Figure 2 shows a schematic flowchart of the uplink and downlink resource joint scheduling method provided in an embodiment of this application. This method can be used in the communication system shown in Figure 1, but the embodiments of this application are not limited thereto.

[0089] As shown in Figure 2, the method may include the following steps:

[0090] S201. The terminal sends a first instruction message to the network device. Correspondingly, the network device can receive the first instruction message sent by the terminal.

[0091] The first indication information is used to indicate the service type of the terminal, and the service type of the terminal includes either the first service type or the second service type.

[0092] Optionally, the terminal and network device can be nodes in a micro-domain network. For example, the terminal can be a production line module, robot, or wearable device in the micro-domain network, and the network device can be a cluster node in the micro-domain network.

[0093] Service type refers to the type of service required by the network where the terminal and network equipment reside. Classified by periodic or non-periodic resource allocation methods, the first service type can refer to service types where uplink and downlink transmissions within the network are periodically correlated; specifically, these can be latency-sensitive service types. The second service type can refer to service types where uplink and downlink transmissions within the network are not periodically correlated; specifically, these can be non-latency-sensitive service types, such as ordinary service types.

[0094] Micro-domain networks (MBNs) can refer to wireless networks designed for short-range communication, which can be deployed in entities such as production line modules, vehicles, and wearable devices. Data within a micro-domain network can bypass the processing of the wide area network (WAN) and core network, reducing data transmission requirements, thereby lowering transmission latency and meeting the extreme transmission performance requirements of related services.

[0095] Optionally, after receiving the first indication information, the network device can determine the service type of the terminal based on the first indication information. The service type of the terminal may be, for example, a first service type or a second service type.

[0096] S202, The network device sends a second instruction message to the terminal. Accordingly, the terminal receives the second instruction message sent by the network device.

[0097] The second instruction information is used to instruct the network device to configure periodic first uplink resources and uplink / downlink resource association information for the terminal according to the terminal's service type. The first uplink resources are used to send uplink information.

[0098] The second indication information can be used to indicate the first uplink resource to the terminal. The terminal can determine the first uplink resource based on the second indication information.

[0099] The second indication information may carry, but is not limited to, at least one of the following: the period, size (e.g., the number of symbols or time slots in the time domain, and the frequency domain range) and location of the uplink resource, the size and period of the associated downlink resource, the subband information corresponding to each uplink and downlink resource (e.g., frame structure, subcarrier spacing, etc.), or the association information of the uplink and downlink resources.

[0100] The network device can send a second indication message if the terminal is in the first service type. In response to the terminal being in the first service type, the network device sends the second indication message to the terminal. That is, if the terminal is in the first service type, the network device configures periodic resources associated with uplink and downlink resources for the terminal.

[0101] S203. Based on the association information between the first uplink resource and the uplink and downlink resources, determine the first downlink resource. The first downlink resource is used to monitor downlink information.

[0102] Optionally, the association information of uplink and downlink resources is the association information of uplink and downlink resources in the time domain.

[0103] Specifically, the first downlink resource is determined based on the temporal correlation information between the first uplink resource and the uplink and downlink resources.

[0104] Optionally, after determining the first uplink resource, the terminal sends uplink information to the network device through the first uplink resource. Accordingly, the network device can receive the uplink information.

[0105] It is understandable that the first uplink resource is configured periodically. A terminal acquiring the first uplink resource may include acquiring the frequency band range (e.g., referred to as the first sub-band) and the period. Then, the terminal can determine the time domain of each first uplink resource based on the period, and determine the frequency domain of the first uplink resource based on the configured frequency band range. Thus, the terminal transmits uplink information through the frequency and time domains of the first uplink resource.

[0106] Before sending the second instruction information, the network device can determine the terminal's first uplink resources and the association information between the uplink and downlink resources. Thus, the network device knows each of the terminal's first uplink resources and the first downlink resources associated with each first uplink resource.

[0107] Furthermore, network devices can receive uplink information from the terminal's first uplink resource.

[0108] After receiving uplink information, network devices can send downlink information to the terminal.

[0109] Furthermore, the network device begins transmitting downlink information at the beginning of the first downlink resource associated with the first uplink resource. The terminal begins listening for the downlink information transmitted by the network device at the beginning of the first downlink resource.

[0110] Optionally, the terminal may listen for downlink information sent by the network device on the first downlink resource.

[0111] Optionally, if the network device determines that it does not need to send downlink information to the terminal, it can release the terminal from occupying the first downlink resources, thereby saving communication resources.

[0112] In addition, network devices can schedule the first downlink resources that a terminal releases from its use to other terminals, thus avoiding the ineffective use of resources and saving communication resources.

[0113] Optionally, the network device can determine whether the terminal needs to listen to downlink information based on whether the terminal needs to conduct downlink communication. For example, if the network device determines that the terminal needs to conduct downlink communication, it determines that it needs to listen to downlink information. If the network device determines that the terminal does not need to conduct downlink communication, it determines that it does not need to listen to downlink information.

[0114] Furthermore, the network device can determine whether the terminal needs to continue downlink communication based on the current communication process status. If the network device determines that the terminal's communication process has not ended, then downlink communication needs to continue. If the network device determines that the terminal's current communication process has ended, then downlink communication does not need to continue.

[0115] If, during the communication process of a terminal accessing a network device, the network device determines that the terminal has not completed access, then it determines that the current communication process of the terminal has not ended. If the terminal has completed access and received feedback from the terminal that the RRC connection has been established, then it determines that the current communication process has ended.

[0116] During data transmission between a terminal and a network device, if the network device completes the data sent by the terminal, it determines that the current communication process of the terminal has ended; if the data reception has not been completed, it determines that the current communication process has not ended.

[0117] Of course, the above communication scenarios are only for illustrative purposes to illustrate how network devices confirm whether the current communication process has ended, and do not constitute a limitation on the specific communication scenarios between terminals and network devices.

[0118] The uplink and downlink resource joint scheduling method provided in this disclosure allows a terminal to indicate its service type to a network device via first indication information. After obtaining the terminal's service type, the network device can configure periodic first uplink resources and associated information for uplink and downlink resources for the terminal via second indication information. When the first uplink resource is determined, the first downlink resource can be determined based on the associated information, enabling flexible scheduling of the first downlink resource. This first uplink resource is used to send uplink information, and the first downlink resource is used to listen for downlink information. Since the uplink resource is configured periodically, and the associated information allows for flexible configuration of downlink resources, unlicensed scheduling of uplink and downlink resources is achieved, reducing unnecessary signaling overhead and latency, and effectively meeting the low-latency transmission requirements of the relevant network.

[0119] In one possible design, the data transmission resources within the same network, i.e., the signal spectrum, can be divided into multiple frequency ranges, each of which can be called a sub-band. After spectrum division, a sub-band set consisting of multiple sub-bands can be obtained. Different frame structures can be configured within the sub-band set, and the frame structure may include, but is not limited to, the configuration ratio of uplink and downlink subframes, subcarrier spacing, etc.

[0120] As one possible implementation, when the terminal is a first service type, the subband where the terminal's first uplink resource is located is the same as the subband where the terminal's first downlink resource is located. That is, when the terminal is a first service type, the first uplink resource and the first downlink resource are distributed on the same subband.

[0121] For ease of understanding, Figure 3a shows an example diagram where uplink and downlink resources are distributed in the same subband. The uplink (UL) 301 corresponding to the first uplink resource and the downlink (DL) 302 corresponding to the first downlink resource are both located in subband n. The uplink 301 corresponding to the first uplink resource is associated with the downlink 302 corresponding to the first downlink resource.

[0122] When the terminal is configured for the first service type, the subband where the terminal's first uplink resource is located is different from the subband where its first downlink resource is located. In other words, when the terminal is configured for the first service type, the first uplink resource and the first downlink resource are distributed on different subbands.

[0123] For ease of understanding, Figure 3b shows an example diagram of uplink and downlink resources distributed in different subbands. Uplink 303, corresponding to the first uplink resource, is located in the first subband, and downlink 304, corresponding to the first downlink resource, is located in the second subband. Uplink 303, corresponding to the first uplink resource, is associated with downlink 304, corresponding to the first downlink resource.

[0124] As another possible implementation, when the terminal is for the first service type, the subband where the terminal's first uplink resource is located is different from the subband where the terminal's first downlink resource is located. That is, when the terminal is for the first service type, the first uplink resource and the first downlink resource are distributed on the same subband.

[0125] When the terminal is configured for the first service type, the subband where the terminal's first uplink resource is located is the same as the subband where its first downlink resource is located. In other words, when the terminal is configured for the first service type, the terminal's first uplink resource and first downlink resource can be distributed on the same subband.

[0126] As an example, the association information can be used to indicate the starting position of the first downlink resource associated with the first uplink resource in the time domain within the same period.

[0127] Furthermore, the terminal can begin listening to downlink information at the beginning of the first downlink resource in the time domain.

[0128] It is understandable that the location of a resource in the time domain can be represented by symbols or time slots in a communication system.

[0129] The terminal can determine the frequency band range (e.g., referred to as the first sub-band) and the starting position in the time domain of the first uplink resource, and start sending uplink information through the first sub-band at the starting position in the time domain of the first uplink resource.

[0130] The terminal can determine the frequency band range (e.g., referred to as the second sub-band) and the starting position in the time domain of the first downlink resource, and listen to downlink information through the second sub-band at the starting position of the first downlink resource in the time domain.

[0131] Optionally, the first subband and the second subband can be configured with the same subcarrier spacing, or with different subcarrier spacings. The different subcarrier spacings are multiples of a power of 2, which facilitates the alignment of the first subband and the second subband.

[0132] Optionally, the frame structure of the second sub-band can be set to the structure corresponding to the downlink sub-frame to avoid the latency problem caused by cross-sub-frame scheduling and ensure that the next position after the last position of the uplink resource can be configured with the associated downlink resource.

[0133] When the terminal belongs to the first service type, there are two resource configuration methods. These two resource configuration methods will be described in detail below.

[0134] Configuration Method 1: Both uplink and downlink resources are configured using periodic static association.

[0135] In one possible design, the associated information may include, but is not limited to, the first offset k1 between the first uplink resource and the first downlink resource in the time domain.

[0136] Furthermore, when the first uplink resource and the first downlink resource are in the same subband, the offset between the first uplink resource and the first downlink resource in the time domain is the first offset k1.

[0137] The first offset k1 can be the time slot interval or symbol interval between the last time slot or symbol of the uplink resource in the same transmission cycle and the starting position of the first downlink resource in the time domain, or the time slot interval or symbol interval between the last time slot interval or symbol of the uplink resource in different transmission cycles and the starting position of the first downlink resource in the time domain.

[0138] Optionally, if the first uplink resource and the first downlink resource are in the same subband, and the transmission of uplink information is completed on the first uplink resource in one transmission cycle, then the starting position of the first downlink resource in the time domain is k1 symbols or time slots away from the last symbol or the time slot of the last symbol of the first uplink resource.

[0139] Figure 4a is an example diagram of uplink and downlink resources in the same subband in the time domain provided by an embodiment of this disclosure. Within transmission period #1, the uplink (UL) of the first uplink resource and the downlink (DL) of the first downlink resource are in the same subband n, and the distance between the last time slot or symbol of the uplink of the first uplink resource and the first time slot or symbol of the downlink of the first downlink resource (that is, the starting position of the first downlink resource in the time domain) is k1 time slots or symbols.

[0140] That is, the terminal starts listening to the downlink information in the downlink of the first downlink resource at the starting position after the last time slot or symbol of the uplink of the first uplink resource and k1 time slots or symbols after that last time slot or symbol.

[0141] Optionally, if the first uplink resource and the first downlink resource are in the same subband, and if the transmission of uplink information is not completed on the first uplink resource in a transmission cycle, then the starting position of the first downlink resource in the time domain is k1 symbols or time slots away from the last symbol or the time slot of the first uplink resource in the transmission cycle in which the uplink information transmission is completed.

[0142] For example, the uplink (UL) of the first uplink resource is the first subband, and the downlink of the first downlink resource is the second subband. If uplink information is transmitted on the uplink of the first uplink resource within transmission period #1, then the distance between the first time slot or symbol of the downlink and the last time slot or symbol of the uplink is k1 time slots or symbols. The network device can configure the first subband of the first uplink resource and the second subband of the first downlink resource for the terminal.

[0143] If the first uplink resource and the first downlink resource are in the same subband, and the uplink information transmission is not completed on the first uplink resource in a transmission cycle, then the starting position of the first downlink resource in the time domain is k1 time slots or symbols away from the last time slot or symbol of the first uplink resource in the transmission cycle in which the uplink information transmission is completed.

[0144] Figure 4b is another example diagram in the time domain of uplink and downlink resources in the same subband provided in this embodiment of the present disclosure. If the first uplink resource does not complete uplink information transmission within transmission period #1, but completes uplink information transmission within transmission period #2, then the transmission period in which the uplink information transmission is completed is transmission period #2. The starting position of the first downlink resource in the time domain is k1 time slots or symbols away from the last time slot or symbol of the first uplink resource in transmission period #2.

[0145] Optionally, if the first uplink resource and the first downlink resource are different subbands, and the first uplink resource completes the transmission of uplink information in one transmission cycle, then the starting position of the first downlink resource in the time domain is k1 time slots or symbols away from the last time slot or symbol of the first uplink resource in the cycle in which the uplink information transmission is completed.

[0146] For example, the uplink (UL) of the first uplink resource is the first subband, and the downlink of the first downlink resource is the second subband. If the first uplink resource fails to complete uplink information transmission within transmission period #1, but completes uplink information transmission within transmission period #2, then the transmission period in which the uplink information transmission is completed is transmission period #2. The starting position of the first downlink resource in the time domain is k1 time slots or symbols away from the last time slot or symbol of the first uplink resource in transmission period #2.

[0147] Configuration Method 2: Uplink resources are configured statically over a periodic period, while downlink resources are configured dynamically and in a periodic period.

[0148] In one possible design, the associated information may include, but is not limited to, the second offset k2 between the first uplink resource and the first downlink resource in the time domain.

[0149] Furthermore, when the first uplink resource and the first downlink resource are different subbands, the time-domain offset between the first uplink resource and the first downlink resource is the second offset k2.

[0150] The second offset k2 can be the time slot interval or symbol interval between the last time slot or symbol of the terminal completing uplink transmission within the same transmission cycle and the starting position of the first downlink resource in the time domain, or the time slot interval or symbol interval between the last time slot or symbol of the terminal completing uplink transmission within different transmission cycles and the starting position of the first downlink resource in the time domain.

[0151] Optionally, if the first uplink resource and the first downlink resource are different subbands, and the uplink information transmission is completed on the first uplink resource in one transmission cycle, then the starting position of the first downlink resource in the time domain is k2 symbols or time slots away from the last symbol or the time slot of the last symbol of the first uplink resource.

[0152] Figure 5a is an example diagram in the time domain of uplink and downlink resources of different sub-bands provided in this embodiment of the present disclosure. The uplink (UL) of the first uplink resource is the first sub-band, and the downlink of the first downlink resource is the second sub-band. If uplink information transmission is completed on the uplink of the first uplink resource within transmission period #1, then the distance between the first time slot or symbol of the downlink and the last time slot or symbol of the uplink information transmission is k2 time slots or symbols. The network device can configure the first sub-band of the first uplink resource and the second sub-band of the first downlink resource for the terminal.

[0153] Optionally, if the first uplink resource and the first downlink resource are in the same subband, and the uplink information transmission is completed on the first uplink resource in one transmission cycle, then the starting position of the first downlink resource in the time domain is k2 time slots or symbols away from the last time slot or symbol of the first uplink resource.

[0154] Optionally, if the first uplink resource and the first downlink resource are different subbands, and if the transmission of uplink information is not completed on the first uplink resource in a transmission cycle, then the starting position of the first downlink resource in the time domain is k2 symbols or time slots away from the last symbol or the time slot of the first uplink resource in the transmission cycle in which the uplink information transmission is completed.

[0155] Figure 5b is another example diagram in the time domain of uplink and downlink resources of different subbands provided in the disclosed embodiment. The uplink (UL) of the first uplink resource is the first subband, and the downlink of the first downlink resource is the second subband. If the first uplink resource does not complete uplink information transmission within transmission period #1, but completes uplink information transmission within transmission period #2, then the transmission period in which the uplink information transmission is completed is transmission period #2. The distance between the starting position of the first downlink resource in the time domain and the last time slot or symbol when the uplink information transmission of the first uplink resource in transmission period #2 is k2 time slots or symbols.

[0156] Optionally, if the first uplink resource and the first downlink resource are in the same subband, and the uplink information transmission is not completed on the first uplink resource in a transmission cycle, then the starting position of the first downlink resource in the time domain is k2 time slots or symbols away from the last time slot or symbol of the first uplink resource in the transmission cycle in which the uplink information transmission is completed.

[0157] In this technical solution, periodic uplink and downlink resources are configured for the terminal, and the configuration of downlink resources is associated with uplink resources, thereby reducing the number of resource configurations, reducing latency and signaling overhead, and meeting the low-latency service transmission requirements of micro-domain networks.

[0158] Figure 6 is another schematic flowchart of a joint uplink and downlink resource scheduling method provided in an embodiment of this disclosure. This method can be used in the communication system shown in Figure 1, but the embodiments of this application are not limited thereto.

[0159] As shown in Figure 6, the joint uplink and downlink resource scheduling method may include the following steps:

[0160] S601. The terminal sends a first indication information to the network device. The first indication information is used to indicate the service type of the terminal. The service type of the terminal includes a first service type or a second service type.

[0161] S602. The terminal receives a second instruction information sent by the network device. The second instruction information is used to instruct the network device to configure periodic first uplink resources and uplink / downlink resource association information for the terminal according to the terminal's service type.

[0162] S603. Based on the association information between the first uplink resource and the uplink and downlink resources, determine the first downlink resource. The first uplink resource is used to send uplink information. The first downlink resource is used to listen for downlink information.

[0163] S604. The terminal sends uplink information on the first uplink resource.

[0164] S605. In response to the completion of uplink information transmission, a third indication message is sent to the network device. Accordingly, the network device can receive the third indication message.

[0165] The third indication message is sent by the terminal after the uplink data transmission is completed. The third indication message is used to indicate that the terminal's uplink transmission has been completed.

[0166] Optionally, if third indication information exists, the first downlink resource can be associated with the completion of the transmission of the third indication information. That is, the starting position of the first downlink resource in the time domain is after the completion of the transmission of the third indication information.

[0167] The distance between the starting position of the first downlink resource in the time domain and the last symbol or the time slot where the last symbol is located when the third indication information transmission is completed is k2 symbols or time slots.

[0168] Optionally, the terminal may determine the last symbol when the third indication information transmission is completed, or the time slot where the last symbol is located, k2 symbols away, or the time slot is the starting position of the first downlink resource in the time domain.

[0169] Optionally, the third indication information can be carried in the fourth signaling, which can be, for example, DCI signaling or MAC CE signaling. In this embodiment, the signaling type is not strictly limited. Taking DCI signaling as an example, an indication field can be set in the DCI signaling, and this indication field can be 1 bit.

[0170] For example, if the indication field is set to 1, the third indication information indicates that the uplink transmission of the terminal has been completed. If the indication field is set to 0, the third indication information indicates that the uplink transmission of the terminal has not been completed.

[0171] Optionally, after sending the third instruction information, the terminal can also listen to downlink information.

[0172] As an optional approach, the uplink and downlink resource joint scheduling method disclosed herein may also include, but is not limited to, the following steps:

[0173] S606. The terminal listens for downlink information on the first downlink resource where the last symbol of the third instruction information transmission is completed or the time slot of the last symbol is k2 symbols or time slots away from the starting position.

[0174] In the uplink and downlink resource joint scheduling method provided in this embodiment, after the terminal sends uplink information through the first uplink resource, it can send a third indication message to the network device in response to the completion of the uplink information transmission. The third indication message instructs the terminal to complete the uplink transmission, enabling the network device to promptly obtain the uplink transmission result. This avoids the waste of communication resources caused by invalid information monitoring. Furthermore, downlink information is monitored on the first downlink resource, starting from a distance of k2 time slots or symbols from where the third indication message transmission is completed. This achieves effective and accurate monitoring of downlink information, avoiding information omissions caused by inaccurate time-domain positioning of the first downlink resource.

[0175] As one embodiment, the network device is further configured to transmit fourth indication information in a first search space during the transmission cycle of the first uplink resource. Correspondingly, the terminal is further configured to receive the fourth indication information.

[0176] The fourth indication information is used to instruct the terminal to discard invalid signals or invalid information received on the first downlink resource.

[0177] The fourth indication information can also be used to indicate that the terminal retains invalid signals or invalid information received on the first downlink resource.

[0178] The fourth instruction information is sent by the network device in the first search space within the transmission cycle of the first uplink resource.

[0179] The first search space is located between the last time slot or symbol of the first downlink resource in the current transmission cycle and the starting position of the first uplink resource in the time domain in the next transmission cycle. The subband of the first search space can be the same as the subband where the first downlink resource is located in the current transmission cycle.

[0180] The current transmission cycle refers to the cycle during which the terminal uses the first uplink resource to send uplink information.

[0181] As shown in Figure 5a, a first search space exists between the last time slot or symbol of the downlink in transmission period #1 and the first time slot or symbol of the uplink in transmission period #2. The subband of the first search space in Figure 5a is the same as the subband of the first downlink resource in its respective period. The first time slot or symbol of the first search space can be located after the last time slot or symbol of the first downlink resource in the time domain.

[0182] The starting slot or symbol of the first search space is after the last slot or symbol of the downlink in the transmission cycle and before the first slot or symbol of the uplink in the next transmission cycle.

[0183] The fourth indication information can be carried within the first signaling. The first signaling can be any type of signaling, such as DCI (Downlink Control Information) signaling, MAC CE (Medium Access Control-Control Element) signaling, etc., and this application does not impose excessive limitations on it. Taking DCI signaling as an example, a new DCI format can be defined and scrambled using a special RNTI (Radio Network Temporary Identifier). For example, a second field can be added to the DCI signaling, which can be named the "Data discard indicator" field. The second field can be 1 bit.

[0184] For example, if the second field is set to 1, the fourth indication information instructs the terminal to discard invalid signals or invalid information received on the first downlink resource. If the second field is set to 0, the fourth indication information instructs the terminal to retain invalid signals or invalid information received on the first downlink resource.

[0185] In the uplink / downlink resource joint scheduling method provided in this disclosure, for micro-domain networks, the network device sends a fourth indication message to the terminal, instructing the terminal to discard invalid signals or invalid information received on the first downlink resource during the current transmission cycle. By directly instructing the network device to discard unnecessary invalid signals or information, the flexibility of the network device in configuring terminal information is effectively improved, thereby effectively reducing the memory occupation of the terminal by invalid signals or information and effectively improving the memory utilization of the terminal.

[0186] As another example, the resource occupancy priority of the terminal of the first service type is higher than that of the terminal of the second service type.

[0187] Optionally, the priority of a terminal's resource usage can be determined by the terminal's service type.

[0188] The terminals corresponding to the first service type are latency-sensitive terminals, requiring low latency. The terminals corresponding to the second service type are non-latency-sensitive terminals, whose transmission needs can be met with normal latency.

[0189] Optionally, when the terminal is of the first service type, within the same transmission cycle, the terminal's occupancy level / priority for the first downlink resources is higher than that of other terminals. Preferably, the service type of the other terminals is the second service type.

[0190] Optionally, when the terminal is a second service type, within the same transmission cycle, the terminal's occupancy level / priority for the first downlink resources is lower than that of other terminals. Preferably, the service type of the other terminals is the first service type.

[0191] Furthermore, network devices can allocate resources to each terminal based on their resource occupancy level or priority. For example, if terminal A has a higher resource occupancy level or priority than terminal B, then when terminal A and terminal B request the same downlink resource, the downlink resource will be allocated to terminal A first.

[0192] Of course, the resource occupancy level / priority of each terminal can also be determined by other indicators, such as network connection status (e.g., network speed, network type). In this embodiment, the method of dividing the terminal occupancy level / priority is not too limited.

[0193] Of course, network devices can also determine which terminal uses the first downlink resource of the current transmission cycle by combining the resource usage priority of each terminal. In addition to using service type to determine the resource usage priority of each terminal, other standards can also be used, such as the urgency of each terminal's communication needs. This embodiment does not impose too many restrictions on this.

[0194] In the uplink and downlink resource joint scheduling method disclosed herein, the resource allocation priority of terminals of the first service type is set higher than that of terminals of the second service type. This ensures that terminals with high latency requirements can promptly occupy sufficient resources, effectively improving communication success rate and efficiency.

[0195] As another embodiment, when the terminal is of the second service type, the network device transmits fifth indication information in the second search space within the current transmission cycle. Correspondingly, the terminal is also used to receive the fifth indication information.

[0196] The fifth instruction information is sent by the network device in the second search space within the transmission cycle of the first uplink resource when the terminal is of the second service type.

[0197] The fifth indication information is used to instruct the terminal to discard downlink information detected in the first downlink resource if the first downlink resource in the previous transmission cycle is occupied by another terminal.

[0198] The fifth instruction information is also used to instruct the terminal to retain downlink information detected by the next downlink resource in the previous transmission cycle if the first downlink resource in the previous transmission cycle is not occupied by other terminals.

[0199] The subband of the second search space is the same as the subband where the first downlink resource of the current transmission cycle is located. The second search space is located between the last position of the first downlink resource in the current transmission cycle and the starting position of the first uplink resource in the time domain of the next transmission cycle. The current transmission cycle refers to the cycle in which the terminal uses the first uplink resource to transmit uplink information.

[0200] The fifth instruction information can be carried in the third signaling. The third signaling can be, for example, DCI signaling or MAC CE signaling. In this embodiment, the signaling type of the third signaling is not limited in much.

[0201] For example, a third field can be added to the DCI signaling, which can be named "Resource Occupation Indication" or "Discard Indication". The third field can be 1 bit.

[0202] For example, if the third field is set to 1, the fifth indication information indicates that the terminal discards the downlink information detected in the first downlink resource if the first downlink resource in the previous transmission cycle is occupied by another terminal. If the third field is set to 0, the fifth indication information indicates that the terminal retains the downlink information detected in the first downlink resource if the first downlink resource in the previous transmission cycle is not occupied by another terminal.

[0203] The network device sends the fifth indication information to the ordinary terminal. Based on the fifth indication information, the ordinary terminal either discards the downlink information detected in the first downlink resource of the previous transmission cycle if the first downlink resource was occupied by another terminal, or retains the downlink information detected in the first downlink resource of the previous transmission cycle if the first downlink resource was not occupied by another terminal.

[0204] For example, the network device can know the resource occupancy status of each terminal. Therefore, for downlink resource S (e.g., time-domain and frequency-domain resources including period T1), if the network device has confirmed that downlink resource S has been allocated to terminal A, then in the next period T2 of period T1, the network device can send a fifth indication message to terminal B. This fifth indication message can instruct terminal B to discard the downlink information received in period T1. In the uplink / downlink resource joint scheduling method provided in this embodiment, the network device can know the resource occupancy status of each terminal. Therefore, when the terminal is a second service type, the network device sends a fifth indication message to the terminal in the second search space within the current transmission period. Thus, discarding downlink information detected in the first downlink resource when it is occupied by other terminals in the previous transmission period can reduce invalid information storage, promptly release the memory occupied by the terminal, and improve the memory utilization rate of the terminal.

[0205] It should be noted that the first search space and the second search space involved in the embodiments of this disclosure may be the same or different, and the number and order of the search spaces are not limited in this embodiment. For example, in the time domain, the first search space may be located before or after the second search space.

[0206] Figure 7 is another schematic flowchart of a joint uplink and downlink resource scheduling method provided in an embodiment of this disclosure. This method can be used in the communication system shown in Figure 1, but the embodiments of this application are not limited thereto.

[0207] As shown in Figure 7, the joint uplink and downlink resource scheduling method may include the following steps:

[0208] S701, The terminal sends the first information to the network device. Accordingly, the network device can receive the first information.

[0209] The first information is used to instruct network devices to allocate a second uplink resource to the terminal.

[0210] Furthermore, the network device can allocate second uplink resources to the terminal based on the first information.

[0211] For example, the first information may be scheduling request information (SR).

[0212] Network devices, such as micro-domain network devices, receive the first information and allocate second uplink resources to the terminal. The second uplink resources can be used to send the second information, specifically by the terminal sending the second information to the network device through the second uplink resources.

[0213] S702. The network device sends resource allocation information to the terminal. Accordingly, the terminal can receive the resource allocation information, which is used to instruct the allocation of a second uplink resource to the terminal.

[0214] Resource allocation information may include the size and location of the second uplink resource. The terminal can determine the second uplink resource based on the resource allocation information.

[0215] S703. The terminal sends second information on the second uplink resource. Accordingly, the network device can receive the second information sent by the terminal on the second uplink resource.

[0216] The second information is used to carry the first indication information. The first indication information is used to indicate the service type of the terminal, and the service type of the terminal includes either the first service type or the second service type.

[0217] The first instruction information can be carried within the second information. For example, the second information can be a Buffer Status Report (BSR) message.

[0218] The first indication information can explicitly indicate the service type of the terminal. For example, the first indication information can be the first field in the second information. Taking the first field as 1 bit as an example, when the first field is 1, the first indication information can indicate that the first service type is the terminal's service type; when the first field is 0, the first indication information can indicate that the second service type is the terminal's service type.

[0219] The first field can be a reused field from the second information, or it can be a newly defined field from the second information.

[0220] For example, the second information is the second signaling, which can be any type of signaling such as MAC CE signaling or DCI signaling. This embodiment does not impose excessive restrictions on the signaling type. When the first field is a newly defined field for the second information, the first field can be, for example, a newly added field in the sub-header of the MAC CE signaling, such as being named the Microarea-service field. For ease of understanding, Figure 8 shows a schematic diagram of the structure of MAC CE signaling. As shown in Figure 8, the "Microarea-service field" is added to the data header H of the MAC CE signaling. This Microarea-service field can be used to carry the second information. Other fields in the data header can be defined or set according to the communication protocol, such as fields like LCID (Logical Channel Identifier). The data fields of MAC CE can be used to cache data.

[0221] Optionally, after determining the service type of the terminal, the network device can configure uplink and downlink resources for the terminal based on the service type.

[0222] Specifically, network devices can configure periodic first uplink resources for terminals, as well as the association information between uplink and downlink resources.

[0223] Furthermore, the network device can generate second indication information based on the periodic first uplink resources configured for the terminal and the associated information of the uplink resources, and then send the second indication information to the terminal.

[0224] S704. The terminal receives a second instruction information sent by the network device. The second instruction information is used to instruct the network device to configure a periodic first uplink resource and the association information of the uplink and downlink resources for the terminal according to the terminal's service type. The first uplink resource is used to send uplink information.

[0225] S705. Based on the association information between the first uplink resource and the uplink and downlink resources, determine the first downlink resource, which is used to monitor downlink information.

[0226] In the technical solution disclosed herein, the configuration of the terminal's service type is quickly completed through signaling interaction between network devices and terminals, thereby achieving the purpose of rapid information interaction.

[0227] Figure 9 is a schematic diagram of the structure of a communication device 900 provided in an embodiment of the present disclosure. The communication device may include a transmitting unit 910, a receiving unit 920, and a processing unit 930.

[0228] In one possible implementation, the communication device 900 can be configured as a terminal or a chip or module within a terminal. The communication device 900 can perform the steps executed by the terminal in the methods shown in Figures 2-7.

[0229] The sending unit 910 can be used to send first indication information to the network device. The first indication information is used to indicate the service type of the terminal. The service type of the terminal includes a first service type or a second service type.

[0230] The receiving unit 920 can be used to: receive second indication information sent by the network device, the second indication information being used to instruct the network device to configure periodic first uplink resources and uplink-downlink resource association information for the terminal according to the terminal's service type, the first uplink resources being used to send uplink information.

[0231] The processing unit 930 can be used to: determine the first downlink resource based on the association information between the first uplink resource and the uplink and downlink resources, wherein the first downlink resource is used to monitor downlink information.

[0232] Optionally, when the terminal is a first service type, the subband where the terminal's first uplink resource is located is the same as the subband where the terminal's first downlink resource is located; or, when the terminal is a first service type, the subband where the terminal's first uplink resource is located is different from the subband where the terminal's first downlink resource is located.

[0233] Optionally, the association information is used to indicate the starting position of the first downlink resource associated with the first uplink resource in the time domain within the same period.
