[0001] CROSS-REFERENCE TO RELATED APPLICATIONS

[0002] This application claims priority to the Chinese patent application filed with the State Intellectual Property Office of the People's Republic of China on June 16, 2023, with application number 202310717697.3 and application name "A communication method and device based on configuration authorization", the entire contents of which are incorporated by reference into this application. Technical Field

[0003] The present application relates to the field of communication technology, and in particular to a communication method and device based on configuration authorization. Background Art

[0004] With the continuous development of wireless communication systems, data transmission latency continues to decrease, and transmission capacity is increasing. Wireless communication systems are gradually infiltrating services that require high real-time performance and large data capacity, such as video transmission, cloud gaming (CG), and extended reality (XR). XR refers to an environment that combines the real and virtual, enabling human-computer interaction, created through computer technology and wearable devices. It is a general term for various forms of reality, including augmented reality (AR), virtual reality (VR), and mixed reality (MR).

[0005] Taking XR services as an example, data frames for XR services can be transmitted between access network devices and terminals using semi-persistent scheduling. For example, the access network device can configure multiple uplink resources to transmit a single data frame. The amount of data carried by these multiple uplink resources may be greater than the data volume of the data frame. To avoid wasting resources, the terminal can notify the access network device of unused uplink resources. How to notify unused uplink resources requires further research.

[0006] Summary of the Invention

[0007] The present application provides a communication method and apparatus for notifying unused uplink resources.

[0008] In a first aspect, an embodiment of the present application provides a communication method, which can be applied to a first device.

The method may include: generating and outputting first indication information. The first indication information includes a first bitmap. The first bit in the first bitmap is used to indicate that the first uplink resource and the second uplink resource are not used, or to indicate that one of the first uplink resource and the second uplink resource is used. The first uplink resource is a resource of the first CG, and the second uplink resource is a resource of the second CG. The first uplink resource and the second uplink resource overlap in time.

[0009] Through this method, when the first uplink resource of the first CG and the second uplink resource of the second CG overlap in time, the first device can indicate through 1 bit that the first uplink resource and the second uplink resource are not used, or indicate that one of the first uplink resource and the second uplink resource is used, thereby reducing signaling overhead and saving transmission resources.

[0010] In a second aspect, an embodiment of the present application provides a communication method, which can be applied to a second device, and the second device can be an access network device or a module (such as a circuit or chip) in the access network device, and can also be a logical node, logical module or software that can realize all or part of the functions of the access network device. The method may include: receiving first indication information, the first indication information includes a first bitmap, the first bit in the first bitmap is used to indicate that the first uplink resource and the second uplink resource are not used, or is used to indicate that one of the first uplink resource and the second uplink resource is used; the first uplink resource is a resource of the first CG, the second uplink resource is a resource of the second CG, and the first uplink resource and the second uplink resource overlap in time.

[0011] Through this method, when the first uplink resource of the first CG and the second uplink resource of the second CG overlap in time, the second device can know through 1 bit that the first uplink resource and the second uplink resource are not used, or indicate that one of the first uplink resource and the second uplink resource is used, thereby reducing signaling overhead and saving transmission resources.

[0012] In a possible design of the first aspect and / or the second aspect, the first bit is also used to indicate that the first uplink resource, the second uplink resource and the third uplink resource are not used, or, is also used to indicate that one of the first uplink resource, the second uplink resource and the third uplink resource is used. The third uplink resource is the resource of the third CG, and the third uplink resource overlaps with at least one of the first uplink resource and the second uplink resource in time. With this design, if the first uplink resource of the first CG and the second uplink resource of the second CG overlap in time, and the third uplink resource of the third CG overlaps with at least one of the first uplink resource and the second uplink resource in time, the first device can indicate that the first uplink resource, the second uplink resource and the third uplink resource are not used, or, indicate that one of the first uplink resource, the second uplink resource and the third uplink resource is used, through 1 bit, thereby further reducing signaling overhead and saving transmission resources.

[0016] 2. Condition 2: The frequency domain resources occupied by the fourth uplink resource are greater than those occupied by the fifth uplink resource. In this way, the resource that occupies more frequency domain resources among the temporally overlapping resources can be recovered as soon as possible, thereby improving resource utilization.

[0017] 3. Condition 3: The fourth uplink resource occupies more time-frequency domain resources than the fifth uplink resource. This allows the resources that occupy more time-frequency domain resources among the temporally overlapping resources to be reclaimed sooner, thereby improving resource utilization.

[0018] 4. Condition 4: The fourth uplink resource is used to carry the second indication information. In this way, the second device can learn as early as possible that the uplink resource carrying the second indication information is used, thereby decoding the uplink resource as early as possible and further learning the unused resources indicated by the second indication information.

This allows the second device to reclaim the resources that occupy more time domain resources among the temporally overlapping resources as soon as possible, thereby improving resource utilization. Furthermore, since the reclaimed resources occupy more time domain resources, their allocation to other terminals can reduce data transmission latency for those terminals.

[0022] 2. Condition 2: The frequency domain resources occupied by the fourth uplink resource are greater than the frequency domain resources occupied by the fifth uplink resource. In this way, the second device can reclaim the resource with more frequency domain resources among the temporally overlapping resources as soon as possible, thereby improving resource utilization.

[0023] 3. Condition 3: The fourth uplink resource occupies more time-frequency domain resources than the fifth uplink resource.

[0025] In a possible design of the third aspect and / or the fourth aspect, the time domain resources occupied by the fourth uplink resource are greater than the time domain resources occupied by the fifth uplink resource, and may include one of the following:

[0026] The start time unit of the fourth uplink resource is the same as the start time unit of the fifth uplink resource, and the end time unit of the fourth uplink resource is after the end time unit of the fifth uplink resource;

[0027] The end time unit of the fourth uplink resource is the same as the end time unit of the fifth uplink resource, and the start time unit of the fourth uplink resource is before the start time unit of the fifth uplink resource;

[0028] The starting time unit of the fourth uplink resource is different from the starting time unit of the fifth uplink resource, the ending time unit of the fourth uplink resource is different from the ending time unit of the fifth uplink resource, and the time domain resources occupied by the fourth uplink resource are more than the time domain resources occupied by the fifth uplink resource.

[0036] In one possible design of the third and / or fourth aspects, the values ​​of the second bit and the third bit are both the first value, indicating that one of the first uplink resource and the second uplink resource is being used. This design specifies the number of bits in the second bitmap and the correspondence between each bit and the indicated resource, thereby avoiding erroneous decoding caused by inconsistent understanding of the number of bits in the second bitmap between the first and second devices. Furthermore, with this design, the first device does not need to sort resources that overlap in time, thereby reducing the implementation complexity of the first device and lowering the requirements on the capabilities of the first device.

Through this design, if the fourth uplink resource of the fourth CG and the fifth uplink resource of the fifth CG overlap in time, and the sixth uplink resource of the sixth CG overlaps in time with at least one of the fourth uplink resource and the fifth uplink resource, the first device accurately indicates through multiple bits that the fourth uplink resource, the fifth uplink resource, and the sixth uplink resource are not used, or indicates that one of the fourth uplink resource, the fifth uplink resource, and the sixth uplink resource is used.

In addition, the time domain resources occupied by the fourth uplink resource are the same as the time domain resources occupied by the fifth uplink resource; and / or, the frequency domain resources occupied by the fourth uplink resource are the same as the frequency domain resources occupied by the fifth uplink resource. Through this design, when the time domain resources and / or frequency domain resources occupied by the fourth uplink resource and the fifth uplink resource are the same, the first device and the second device can determine the order of the second bit corresponding to the fourth uplink resource and the third bit corresponding to the fifth uplink resource, thereby avoiding erroneous decoding caused by the first device and the second device having inconsistent understanding of the correspondence between each bit and the indicated resource.

[0063] The technical solutions in the embodiments of the present application will be described below in conjunction with the accompanying drawings in the embodiments of the present application. The technical solutions in the embodiments of the present application can be applied to various communication systems, such as universal mobile telecommunications system (UMTS), wireless local area network (WLAN), wireless fidelity (Wi-Fi) system, 4th generation (4G) mobile communication system, such as long term evolution (LTE) system, fifth generation (5G) mobile communication system, such as new radio (NR) system, and future evolved communication systems, such as sixth generation (6G) mobile communication system.

[0064] This application will present various aspects, embodiments, or features in the context of systems that may include multiple devices, components, modules, etc. It should be understood and appreciated that each system may include additional devices, components, modules, etc., and / or may not include all of the devices, components, modules, etc. discussed in conjunction with the figures. Furthermore, combinations of these aspects may also be used.

[0065] To facilitate understanding of the embodiments of the present application, Figure 1 shows a possible, non-limiting system diagram. As shown in Figure 1, a communication system 10 includes a radio access network (RAN) 100 and a core network (CN) 200. Optionally, the communication system 10 may also include the Internet 300.

[0066] The RAN 100 includes at least one RAN node (e.g., 110a and 110b in FIG. 1 , collectively referred to as 110) and at least one terminal (e.g., 120a-120j in FIG. 1 , collectively referred to as 120). The RAN 100 may also include other RAN nodes, such as wireless relay equipment and / or wireless backhaul equipment (not shown in FIG. 1 ). The terminal 120 is wirelessly connected to the RAN node 110. The RAN node 110 is wirelessly or wiredly connected to the core network 200. The core network equipment in the core network 200 and the RAN node 110 in the RAN 100 may be separate physical devices, or they may be a single physical device that integrates core network logical functions and radio access network logical functions.

[0067] The RAN 100 may be a cellular system related to the Third Generation Partnership Project (3GPP), such as a 4G or 5G mobile communication system, or a future-oriented evolutionary system (such as a 6G mobile communication system). The RAN 100 may also be an open access network (O-RAN or ORAN), a cloud radio access network (CRAN), or a WiFi system. The RAN 100 may also be a communication system that integrates two or more of the above systems.

[0068] The RAN node 110, sometimes also referred to as a RAN entity or access node, constitutes part of the communication system and facilitates wireless access for terminals. Multiple RAN nodes 110 in the communication system 10 can be of the same type or different types. In some scenarios, the roles of the RAN node 110 and the terminal 120 are relative. For example, the network element 120i in Figure 1 can be a helicopter or drone, which can be configured as a mobile base station. For terminals 120j accessing the RAN 100 via network element 120i, network element 120i is a base station; however, for base station 110a, network element 120i is a terminal. The RAN node 110 and the terminal 120 are sometimes referred to as communication devices. For example, network elements 110a and 110b in Figure 1 can be understood as communication devices with base station functionality, and network elements 120a-120j can be understood as communication devices with terminal functionality.

[0069] The RAN node can also be expressed in different ways, such as access network equipment. Unless otherwise specified in this application, the access network equipment is used to express it.

[0070] In one possible scenario, the access network device may be a base station, an evolved NodeB (eNodeB), an access point (AP), a transmission reception point (TRP), a next generation NodeB (gNB), a next generation base station in a 6G mobile communication system, a base station in a future mobile communication system, or an access node in a WiFi system, etc. The access network device may be a macro base station (such as 110a in Figure 1), a micro base station or an indoor station (such as 110b in Figure 1), a relay node or a donor node, or a wireless controller in a CRAN scenario. Optionally, the access network device may also be a server, a wearable device, a vehicle or an on-board device, etc. For example, the access network device in the vehicle to everything (V2X) technology may be a road side unit (RSU). All or part of the functions of the access network device in this application may also be implemented by software functions running on hardware, or by virtualization functions instantiated on a platform (such as a cloud platform). The access network device in this application may also be a logical node, a logical module or software that can implement all or part of the functions of the access network device.

[0071] In another possible scenario, multiple access network devices collaborate to assist the terminal 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 be included in the same network element, such as a baseband unit (BBU). The RU can be included in a radio frequency device or radio frequency unit, such as a remote radio unit (RRU), an active antenna unit (AAU), or a remote radio head (RRH).

[0072] 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.

[0073] A terminal may also be referred to as a terminal device, user equipment (UE), mobile station, mobile terminal, etc. Terminals can be widely used in various scenarios, such as device-to-device (D2D), vehicle-to-everything (V2X) communication, machine-type communication (MTC), Internet of Things (IOT), virtual reality, augmented reality, industrial control, autonomous driving, telemedicine, smart grid, smart furniture, smart office, smart wearable, smart transportation, smart city, etc. A terminal may be a mobile phone, tablet computer, computer with wireless transceiver function, wearable device, vehicle, drone, helicopter, airplane, ship, robot, robotic arm, smart home device, etc. The embodiments of the present application do not limit the device form of the terminal.

[0074] In this application, "sending information to...(terminal)" can be understood as the destination of the information being the terminal, and can include directly or indirectly sending information to the terminal. "Receiving information from...(terminal)" can be understood as the source of the information being the terminal, and can include directly or indirectly receiving information from the terminal. The information may undergo necessary processing 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 repeated here.

[0075] The communication system and business scenarios described in the embodiments of the present application are intended to more clearly illustrate the technical solutions of the embodiments of the present application, and do not constitute a limitation on the technical solutions provided in the embodiments of the present application. A person skilled in the art will appreciate that, with the evolution of network architecture and the emergence of new business scenarios, the technical solutions provided in the embodiments of the present application are also applicable to similar technical problems.

[0076] The following first explains the relevant terms involved in the embodiments of the present application. It should be noted that these explanations are intended to make the embodiments of the present application easier to understand and should not be regarded as limiting the scope of protection claimed by this application.

[0077] 1) Semi-static scheduling:

[0078] In semi-persistent scheduling, the access network device can allocate periodic uplink resources and / or downlink resources to the terminal. Taking uplink resources as an example, semi-persistent scheduling for allocating uplink resources can include CG. CG means that during uplink transmission, the access network device allocates periodic uplink resources through radio resource control (RRC) signaling and / or downlink control information (DCI). The terminal can then use one or more of these periodic uplink resources for uplink transmission.

[0079] The transmission resource used for an uplink transmission may be referred to as a CG transmission opportunity (or simply referred to as a transmission opportunity). The CG transmission opportunity may also be replaced by other possible descriptions, such as CG resources or (physical uplink shared channel, PUSCH) resources or PUSCH opportunities or PUSCH opportunities or CG uplink resources or CG PUSCH resources or CG PUSCH transmission resources.

[0080] 2) UTO-UCI:

[0081] A CG cycle (also called a CG cycle) may include multiple PUSCH resources. The resources of CG are fixed, while the resources required for XR services will change with changes in the amount of data. For example, for AR services, changes in the scene content display are caused by changes in the focus target and changes in the spatial relationship between the position and the gaze point (action). The uplink transmission content contains the visual information required for perception (including depth). The uplink transmission is mainly clear and stable pictures or video streams, and can also be some extracted environmental feature information. The data volume of these contents may change. Therefore, if more CG resources are configured for the terminal, there may be a waste of resources.

[0082] To avoid wasting resources, the terminal can send a UTO-UCI to the access network device. The UTO-UCI can indicate unused PUSCH resources so that the access network device can reallocate these resources to other terminals. For example, as shown in Figure 2, a CG period includes four PUSCH resources. The terminal can send a UTO-UCI on the first PUSCH resource to inform the access network device that the last two PUSCH resources in this CG period are not used. Figure 2 uses the example of sending the UTO-UCI on the first PUSCH resource. It should be understood that the terminal can also send the UTO-UCI through other PUSCH resources, for example, the terminal sends the UTO-UCI through each PUSCH resource it uses. It should also be understood that the UTO-UCI may also be replaced by other possible descriptions, such as XR-UCI or UCI used to indicate unused resources.

[0083] The UTO-UCI may indicate unused PUSCH resources in a variety of ways. For example, the UTO-UCI may indicate whether each PUSCH resource is used within a period of time through a bitmap. The period of time may be, for example, a CG cycle or a set time period. The UTO-UCI may also indicate unused PUSCH resources in other ways. This application does not limit the indication method of the UTO-UCI.

[0084] 3) Time unit generally refers to a unit of time. For example, a time unit may be, but is not limited to, a subframe, a slot, a symbol, etc. The symbol may be a time domain symbol (e.g., an orthogonal frequency division multiplexing (OFDM) symbol).

[0085] 4) Frequency unit generally refers to a unit of frequency resources. For example, a frequency unit may be, but is not limited to, a resource block (RB), a resource block group (RBG), etc.

[0086] Currently, access network equipment can configure multiple CG resources for the terminal. In this case, UTO-UCI can indicate whether the resources of the multiple CGs are used. Exemplarily, the multiple CGs include CG1 and CG2. The resource configuration of CG1 is different from the resource configuration of CG2. For example, in each CG cycle, the number of resources of CG1 is different from the number of resources of CG2; and / or, the cycle of CG1 is different from the cycle of CG2. A bitmap in the UTO-UCI can be used to indicate whether the resources of CG1 and CG2 are used. Resources in different CGs may overlap in time. How to indicate whether the resources that overlap in time are used requires further attention.

[0087] Based on this, an embodiment of the present application provides a communication method. Figure 3 is a flow chart corresponding to the communication method provided in an embodiment of the present application. In Figure 3, the method is illustrated by taking the first device and the second device as the execution subjects of the interaction diagram as an example, but the present application does not limit the execution subjects of the interaction diagram. For example, the first device can be a terminal, or a module applied to the terminal, such as a chip, a chip system, or a processor, or a logical node, a logical module, or software that can realize all or part of the terminal functions; the second device can also be an access network device, or a module applied to the access network device, such as a chip, a chip system, or a processor, or a logical node, a logical module, or software that can realize all or part of the access network device functions.

[0088] As shown in FIG3 , the method includes the following steps:

[0089] S301: A first apparatus generates first indication information, the first indication information including a first bitmap, wherein a first bit in the first bitmap is used to indicate that a first uplink resource and a second uplink resource are not used, or to indicate that one of the first uplink resource and the second uplink resource is used. The first bit may be 1 bit.

[0090] The first uplink resource is a resource of the first CG, for example, a PUSCH resource of the first CG; the second uplink resource is a resource of the second CG, for example, a PUSCH resource of the second CG. The first uplink resource and the second uplink resource overlap in time. For example, the first uplink resource and the second uplink resource may partially overlap in time or completely overlap in time. In addition, the first uplink resource and the second uplink resource may overlap or not overlap in the frequency domain, which is not limited in this application.

[0091] Exemplarily, the resources of the first CG and the resources of the second CG may be configured by the second device for the first device. For example, the second device may send first configuration information and second configuration information to the first device, the first configuration information is used to configure the resources of the first CG, and the second configuration information is used to configure the resources of the second CG. Among them, a cycle of the first CG may include multiple resources, and a cycle of the second CG may also include multiple resources. The first configuration information and the second configuration information may be carried in the same message or in different messages, and this application does not limit this. Optionally, the resources of the first CG and the resources of the second CG may be determined by the second device based on the amount of data to be sent by the first device. For example, the amount of data to be sent is proportional to the number of resources of the first CG and the second CG.

[0092] After receiving the first configuration information and the second configuration information, the first device may determine that the first uplink resource and the second uplink resource overlap in time, and determine the usage of the first uplink resource and the second uplink resource, thereby generating the first indication information.

[0093] In some examples, the first device determines that the first uplink resource and the second uplink resource are not used, thereby generating first indication information indicating that the first uplink resource and the second uplink resource are not used. For example, when all data to be sent can be sent via resources before the first uplink resource and the second uplink resource, the first device may determine that the first uplink resource and the second uplink resource are not used.

[0094] In other examples, the first device determines that one of the first uplink resource and the second uplink resource is used, thereby generating first indication information indicating that one of the first uplink resource and the second uplink resource is used. For example, when the resources before the first uplink resource and the second uplink resource are insufficient to send all the data to be sent, the first device may determine that one of the first uplink resource and the second uplink resource is used. When one of the first uplink resource and the second uplink resource is used, the first device may select one of the first uplink resource and the second uplink resource to send uplink data according to a set rule. The set rule is, for example, to select the resource with the highest priority among the resources overlapping in time to send uplink data. For example, when one of the first uplink resource and the second uplink resource is used, and the priority of the first uplink resource is higher than the priority of the second uplink resource, the first device may select the first uplink resource to send uplink data.

[0095] As mentioned above, the first bit is used to indicate that the first uplink resource and the second uplink resource are not used, or to indicate that one of the first uplink resource and the second uplink resource is used. There are multiple specific indication modes, for example, indication mode 1 and indication mode 2.

[0096] (1) Instruction method 1:

[0097] The first bit is used to indicate that the first uplink resource and the second uplink resource are not used. Optionally, when the value of the first bit is value #1, it indicates that the first uplink resource and the second uplink resource are not used. Value #1 is, for example, 0 or 1. The following description takes value #1 as 0 as an example.

[0098] For example, as shown in Figure 4A, the first uplink resource is resource 5 of CG1, and the second uplink resource is resource 6 of CG2. The first device sends uplink data using the following resources: resource 2 and resource 4 of CG1, and resource 1 and resource 3 of CG2. The first bit may be the fifth bit in the first bitmap, and the value of the bit is 0, indicating that resource 5 and resource 6 are not used.

[0099] (2) Instruction method 2:

[0100] The first bit is used to indicate that one of the first uplink resource and the second uplink resource is being used. Optionally, when the first bit is value #2, it indicates that one of the first uplink resource and the second uplink resource is being used. Value #2 is, for example, 1 or 0. Value #2 can be different from value #1, for example, value #1 is 0 and value #2 is 1, or vice versa. The following description uses value #2 being 1 as an example.

[0101] For example, as shown in FIG4B , the first uplink resource is resource 1 of CG1, and the second uplink resource is resource 2 of CG2. The first device sends uplink data using the following resources: one of resource 1 and resource 2, resource 3 of CG1, and resource 4 of CG2. The first bit may be the first bit in the first bitmap, and a value of 1 indicates that one of resource 1 and resource 2 is used.

[0102] In some possible embodiments, the first bitmap may further indicate whether the following resources are used: one or more resources other than the first uplink resources in the resources of the first CG, and / or one or more resources other than the second uplink resources in the resources of the second CG. That is, the first bitmap may further indicate whether one or more resources that do not overlap in time in the resources of the first CG and the resources of the second CG are used.

[0103] Optionally, a bit in the first bitmap may correspond to one or more resources, and the value of the bit is used to indicate whether the resource corresponding to the bit is used. For example, the value of the bit is 0, indicating that the resource corresponding to the bit is not used, and the value of the bit is 1, indicating that the resource corresponding to the bit is used, or vice versa. When a bit indicates whether the resources overlapping in time among the resources of the first CG and the resources of the second CG are used, the bit corresponds to multiple resources overlapping in time. For example, the first bit corresponds to 2 resources, namely the first uplink resource and the second uplink resource. When a bit indicates whether the resources not overlapping in time among the resources of the first CG and the resources of the second CG are used, the bit may correspond to one resource. In the first bitmap, the order of the bits can be determined according to the start time of the resources corresponding to the bits. For example, the earlier the start time of the PUSCH resource corresponding to a bit is, the closer the position of the bit in the first bitmap is.

[0104] For example, still taking FIG. 4A as an example, the first bitmap may include 5 bits, where bits 1 to 4 in the first bitmap correspond to resource 1 of CG2, resource 2 of CG1, resource 3 of CG2, and resource 4 of CG1, respectively, and bit 5 in the first bitmap corresponds to resource 5 of CG1 and resource 6 of CG2. When the value of the first bitmap is 11110, it indicates that resources 1 to 4 are used, and resources 5 and 6 are not used.

[0105] For another example, still taking FIG. 4B as an example, the first bitmap may include 5 bits, the first bit in the first bitmap corresponds to resource 1 of CG1 and resource 2 of CG2, and the second to fifth bits in the first bitmap correspond to resource 3 of CG1, resource 4 of CG2, resource 5 of CG1, and resource 6 of CG2, respectively. When the value of the first bitmap is 11100, it indicates that one of resource 1 and resource 2 is used, resource 3 and resource 4 are used, and resource 5 and resource 6 are not used.

[0106] S302: The first device outputs first indication information. Correspondingly, the second device receives the first indication information.

[0107] In some possible implementations, the first device may be a module within the terminal, such as a chip. After generating the first indication information, the first device may output the first indication information to another module within the terminal, such as a radio frequency module. The other module in the terminal may then send the first indication information to the second device.

[0108] In some other possible ways, the first device may send the first indication information to the second device. In this case, the first device may be a terminal and the second device may be an access network device.

[0109] It can be understood that the above-mentioned first indication information can be carried in a variety of possible signaling, for example, carried in UCI, and the UCI can be CG-UCI or UTO-UCI.

[0110] After receiving the first indication information, the second device may determine the usage of the first uplink resource and the second uplink resource based on the first bit in the first indication information. For example, when the first bit is used to indicate that the first uplink resource and the second uplink resource are not used, the second device may determine that the first uplink resource and the second uplink resource are not used, so that the first uplink resource and / or the second uplink resource can be allocated to other terminals, thereby improving resource utilization. For another example, when the first bit is used to indicate that one of the first uplink resource and the second uplink resource is used, the second device may determine which of the first uplink resource and the second uplink resource is used and which is not used according to the set rules, so that the unused resources can be allocated to other terminals, thereby improving resource utilization. The specific content of the set rules can be referred to S301 and will not be repeated here.

[0111] Through the method shown in Figure 3, when the first uplink resource of the first CG and the second uplink resource of the second CG overlap in time, the first device can indicate through 1 bit that the first uplink resource and the second uplink resource are not used, or indicate that one of the first uplink resource and the second uplink resource is used, thereby reducing signaling overhead and saving transmission resources.

[0112] Furthermore, this method specifies the number of bits in the first bitmap and the correspondence between each bit and the indicated resource, thereby avoiding decoding errors caused by a disagreement between the first and second devices regarding the number of bits in the first bitmap and the correspondence between each bit and the indicated resource. Furthermore, this method eliminates the need for the first device to sort temporally overlapping PUSCH resources, thereby reducing the implementation complexity of the first device and lowering the capability requirements placed on the first device.

[0113] It should be understood that the method shown in FIG3 is described by taking two resources overlapping in time as an example. In actual use, the resources overlapping in time may also be more than two resources. In this case, the method shown in FIG3 is still applicable.

[0114] The following description uses an example in which resources overlapping in time include a first uplink resource, a second uplink resource, and a third uplink resource. The third uplink resource is a resource of a third CG, and the third uplink resource overlaps in time with at least one of the first uplink resource and the second uplink resource. Furthermore, the third uplink resource may or may not overlap with at least one of the first uplink resource and the second uplink resource in the frequency domain, which is not limited in this application.

[0115] In this case, the first bit may also be used to indicate that the first uplink resource, the second uplink resource, and the third uplink resource are not used, or may also be used to indicate that one of the first uplink resource, the second uplink resource, and the third uplink resource is used. The indication method of the first bit may refer to indication method 1 and indication method 2 in S301, except that the first uplink resource and the second uplink resource are replaced by the first uplink resource, the second uplink resource, and the third uplink resource, and the repeated parts are not repeated here.

[0116] There may be multiple relationships between the third uplink resource and the first uplink resource and the second uplink resource, for example, relationship 1 and relationship 2.

[0117] (1) Relationship 1: The third uplink resource temporally overlaps with both the first and second uplink resources. For example, as shown in Figure 4C , the first uplink resource is resource 5 of CG1, the second uplink resource is resource 4 of CG2, and the third uplink resource is resource 6 of CG3. Resource 6 temporally overlaps with both resource 4 and resource 5.

[0118] (2) Relationship 2: The third uplink resource overlaps with one of the first uplink resource and the second uplink resource in time. Optionally, the resource of the first uplink resource and the second uplink resource that overlaps with the third uplink resource is used to transmit uplink data. For example, as shown in Figure 4D, the first uplink resource is resource 5 of CG1, the second uplink resource is resource 4 of CG2, and the third uplink resource is resource 6 of CG3. Resource 5 and resource 6 overlap in time, but resource 4 and resource 6 do not overlap in time. Resource 5 is used to transmit uplink data.

[0119] It should be noted that the third uplink resource may be one or more resources. Exemplarily, when the third uplink resource is one resource, the third uplink resource may be a resource in one CG; when the third uplink resource is multiple resources, the third uplink resource may be a resource in multiple CGs, and the third uplink resource in each CG overlaps with at least one of the first uplink resource and the second uplink resource in time. In addition, when the third uplink resource is multiple resources, the relationship between the multiple resources and the first uplink resource and the second uplink resource may all be relationship 1, or may all be relationship 2, or the relationship between a part of the multiple resources and the first uplink resource and the second uplink resource may be relationship 1, and the relationship between another part of the multiple resources and the first uplink resource and the second uplink resource may be relationship 2.

[0120] Through this method, if the first uplink resource of the first CG and the second uplink resource of the second CG overlap in time, and the third uplink resource of the third CG overlaps in time with at least one of the first uplink resource and the second uplink resource, the first device can indicate through 1 bit that the first uplink resource, the second uplink resource and the third uplink resource are not used, or indicate that one of the first uplink resource, the second uplink resource and the third uplink resource is used, thereby further reducing signaling overhead and saving transmission resources.

[0121] In some possible ways, if uplink resource #A overlaps with one of the first uplink resource and the second uplink resource in time, and the resource of the first uplink resource and the second uplink resource that does not overlap with uplink resource #A is used to transmit uplink data, then the first bit in the first bitmap is used to indicate that one of the first uplink resource and the second uplink resource is used, and bit #A in the first bitmap is used to indicate whether uplink resource #A is used. For example, as shown in Figure 4D, the first uplink resource is resource 5 of CG1, the second uplink resource is resource 4 of CG2, and uplink resource #A is resource 6 of CG3. Resource 5 and resource 6 overlap in time, but resource 4 and resource 6 do not overlap in time. If resource 4 is used to transmit uplink data, then in the first bitmap, the first bit is used to indicate that one of resource 4 and resource 5 is used, and bit #A is used to indicate whether resource 6 is used. In this way, the first device can accurately indicate, through 2 bits, whether one of the first uplink resource and the second uplink resource is used, and whether uplink resource #A is used, thereby reducing signaling overhead and saving transmission resources.

[0122] An embodiment of the present application provides another communication method. Figure 5 is a flow chart corresponding to the communication method provided by an embodiment of the present application. Figure 5 illustrates the method by taking the first device and the second device as the execution subjects of the interaction diagram as an example, but the present application does not limit the execution subjects of the interaction diagram. For example, the first device can be a terminal, or a module applied to the terminal such as a chip, a chip system, or a processor, or a logical node, a logical module, or software that can realize all or part of the terminal functions; the second device can also be an access network device, or a module applied to the access network device such as a chip, a chip system, or a processor, or a logical node, a logical module, or software that can realize all or part of the access network device functions.

[0123] As shown in FIG5 , the method includes the following steps:

[0124] S501: A first apparatus generates second indication information, the second indication information including a second bitmap, wherein a second bit and a third bit in the second bitmap are used to indicate that a fourth uplink resource and a fifth uplink resource are not used, or to indicate that one of the fourth uplink resource and the fifth uplink resource is used. The second bit and the third bit may both be 1 bit.

[0125] The fourth uplink resource is a resource of the fourth CG, for example, a PUSCH resource of the fourth CG; the fifth uplink resource is a resource of the fifth CG, for example, a PUSCH resource of the fifth CG. The fourth uplink resource and the fifth uplink resource overlap in time. For example, the fourth uplink resource and the fifth uplink resource may partially overlap in time or completely overlap in time. In addition, the fourth uplink resource and the fifth uplink resource may overlap or not overlap in the frequency domain, which is not limited in this application.

[0126] Exemplarily, the resources of the fourth CG and the resources of the fifth CG may be configured by the second device for the first device. The configuration method may refer to the configuration method of the resources of the first CG and the resources of the second CG in S301, except that the first CG is replaced by the fourth CG and the second CG is replaced by the fifth CG, which will not be repeated here. After receiving the configuration information of the resources of the fourth CG and the configuration information of the resources of the fourth CG, the first device may determine that the fourth uplink resources and the fifth uplink resources overlap in time, and determine the usage of the fourth uplink resources and the fifth uplink resources, thereby generating the second indication information. The method for the first device to determine the usage of the fourth uplink resources and the fifth uplink resources may refer to the method for determining the usage of the first uplink resources and the second uplink resources in S301, except that the first uplink resources are replaced by the fourth uplink resources and the second uplink resources are replaced by the fifth uplink resources, which will not be repeated here.

[0127] As previously mentioned, the second bit and the third bit in the second bitmap are used to indicate that the fourth uplink resource and the fifth uplink resource are not used, or to indicate that one of the fourth uplink resource and the fifth uplink resource is used. There may be multiple specific indication modes, for example, indication mode 1, indication mode 2, and indication mode 3.

[0128] (1) Instruction method 1:

[0129] When the values ​​of the second bit and the third bit are both the first value, it indicates that one of the fourth uplink resource and the fifth uplink resource is used. The first value is, for example, 1 or 0. The following description takes the first value of 1 as an example.

[0130] For example, as shown in Figure 6A, the fourth uplink resource is resource 1 of CG1, and the fifth uplink resource is resource 2 of CG2. The first device sends uplink data using the following resources: one of resource 1 and resource 2, resource 3 of CG1, and resource 4 of CG2. The second bit and the third bit are the first and second bits in the second bitmap, respectively. The values ​​of the second bit and the third bit are both 1, indicating that one of resource 1 and resource 2 is used.

[0131] (2) Instruction method 2:

[0132] When the values ​​of the second bit and the third bit are both the second value, it indicates that the fourth uplink resource and the fifth uplink resource are not used. The second value is, for example, 0 or 1. The second value can be different from the first value, for example, the first value is 1 and the second value is 0, or vice versa. The following description uses the second value of 0 as an example.

[0133] For example, as shown in Figure 6B , the fourth uplink resource is resource 5 of CG1, and the fifth uplink resource is resource 6 of CG2. The first device sends uplink data using the following resources: resource 1 and resource 3 of CG1, and resource 2 and resource 4 of CG2. The second bit and the third bit are the fifth and sixth bits in the second bitmap, respectively. The values ​​of the second bit and the third bit are both 0, indicating that resource 5 and resource 6 are not used.

[0134] (3) Instruction method three:

[0135] When the fourth uplink resource and the fifth uplink resource overlap in time, the first device uses at most one of the resources for uplink transmission. When one of the fourth uplink resource and the fifth uplink resource is used, the second bit can be used to indicate whether the fourth uplink resource is used, and the third bit can be used to indicate whether the fifth uplink resource is used. Optionally, when the value of the second bit is the first value, it indicates that the fourth uplink resource is used, and when the value of the second bit is the second value, it indicates that the fourth uplink resource is not used; when the value of the third bit is the first value, it indicates that the fifth uplink resource is used, and when the value of the third bit is the second value, it indicates that the fifth uplink resource is not used. The specific contents of the first value and the second value can be referred to indication method one and indication method two, and will not be repeated here. The following is an example of the first value being 1 and the second value being 0.

[0136] For example, as shown in Figure 6C, the fourth uplink resource is resource 1 of CG1, and the fifth uplink resource is resource 2 of CG2. Since the priority of resource 1 is higher than the priority of resource 2, the first device uses the following resources to send uplink data: resource 1 and resource 3 of CG1, and resource 4 of CG2. The second bit and the third bit can be the first and second bits in the second bitmap, respectively. The value of the second bit is 1, and the value of the third bit is 0, indicating that resource 1 is used and resource 2 is not used.

[0137] In some possible embodiments, the second bitmap may further indicate whether the following resources are used: one or more resources other than the fourth uplink resources in the resources of the fourth CG, and / or one or more resources other than the fifth uplink resources in the resources of the fifth CG. That is, the second bitmap may further indicate whether one or more resources that do not overlap in time in the resources of the fourth CG and the resources of the fifth CG are used.

[0138] Optionally, a bit in the second bitmap may correspond to a resource, and the value of the bit is used to indicate whether the resource corresponding to the bit is used. For example, a value of 0 for the bit indicates that the resource corresponding to the bit is not used, and a value of 1 for the bit indicates that the resource corresponding to the bit is used, or vice versa. In the second bitmap, the order of the bits may be determined according to the start time of the resource corresponding to each bit. For example, the earlier the start time of the PUSCH resource corresponding to a bit is, the earlier the position of the bit in the second bitmap is.

[0139] For example, still taking FIG6A as an example, the second bitmap may include 6 bits, and bits 1 to 6 in the second bitmap correspond to resource 1 of CG1, resource 2 of CG2, resource 3 of CG1, resource 4 of CG2, resource 5 of CG1, and resource 6 of CG2, respectively. When the value of the second bitmap is 111100, it indicates that one of resource 1 and resource 2 is used, resource 3 and resource 4 are used, and resource 5 and resource 6 are not used.

[0140] For another example, still taking FIG. 6B as an example, the second bitmap may include 6 bits, and bits 1 to 6 in the second bitmap correspond to resource 1 of CG1, resource 2 of CG2, resource 3 of CG1, resource 4 of CG2, resource 5 of CG1, and resource 6 of CG2, respectively. When the second bitmap takes a value of 111100, it indicates that resources 1 to 4 are used, and resources 5 and 6 are not used.

[0141] For another example, still taking Figure 6C as an example, the second bitmap may include 6 bits, and bits 1 to 6 in the second bitmap correspond to resource 1 of CG1, resource 2 of CG2, resource 3 of CG1, resource 4 of CG2, resource 5 of CG1, and resource 6 of CG2, respectively. When the value of the second bitmap is 101100, it means that resources 1, 3, and 4 are used, and resources 2, 5, and 6 are not used.

[0142] Currently, the number of bits in the bitmap that the first device can send at a time is limited. Therefore, the second bit and the third bit in the second bitmap may be transmitted in different PUSCH resources. The second bit corresponds to the fourth uplink resource, and the third bit corresponds to the fifth uplink resource. For example, the second bit can be used to indicate whether the fourth uplink resource is used, and the third bit can be used to indicate whether the fifth uplink resource is used. In this way, the moment when the second device learns whether the fourth uplink resource is used may be different from the moment when the second device learns whether the fifth uplink resource is used.

[0143] For example, as shown in Figure 6D, the fourth uplink resource is resource 4 of CG1, and the fifth uplink resource is resource 3 of CG2. Among them, the time-frequency domain resources occupied by resource 4 are more than the time-frequency domain resources occupied by resource 3. At present, the order of each bit can be determined according to the start time of the resource corresponding to each bit. If the number of bits in the bit map that can be sent by the first device each time is 3, then in the bit map sent by the first device for the first time, 3 bits can respectively indicate whether resources 1 to resources 3 are used, and in the bit map sent by the first device for the second time, 3 bits can respectively indicate whether resources 4 to resources 6 are used. If resource 4 is an unused resource, the second device needs to reclaim the resource after receiving the bit map sent for the second time, which reduces the resource utilization.

[0144] Therefore, in the second bitmap, the second bit may precede the third bit. That is, the second bit is the higher-order bit of the third bit, or the third bit is the lower-order bit of the second bit. Furthermore, one of the following conditions 1 to 3 may be satisfied. In other words, when one of the following conditions 1 to 3 is satisfied, the second bit may precede the third bit in the second bitmap.

[0145] (1) Condition 1: The fourth uplink resource occupies more time domain resources than the fifth uplink resource. This allows the second device to reclaim the resources that occupy more time domain resources from the temporally overlapping resources as soon as possible, thereby improving resource utilization. Furthermore, since the reclaimed resources occupy more time domain resources, allocating them to other terminals can reduce data transmission latency for those other terminals.

[0146] In some examples, if the start time unit of the fourth uplink resource is the same as the start time unit of the fifth uplink resource, and the end time unit of the fourth uplink resource is after the end time unit of the fifth uplink resource, then condition 1 is satisfied. For example, as shown in Figure 6E, the fourth uplink resource is resource 3 of CG1, and the fifth uplink resource is resource 4 of CG2. The start symbol of resource 3 is the same as the start symbol of resource 4, and the end symbol of resource 3 is after the end symbol of resource 4. Therefore, condition 1 is satisfied.

[0147] In other examples, if the end time unit of the fourth uplink resource is the same as the end time unit of the fifth uplink resource, and the start time unit of the fourth uplink resource is before the start time unit of the fifth uplink resource, then condition 1 is satisfied. For example, as shown in Figure 6F, the fourth uplink resource is resource 3 of CG1, and the fifth uplink resource is resource 4 of CG2. The start symbol of resource 3 is before the start symbol of resource 4, and the end symbol of resource 3 is the same as the end symbol of resource 4. Therefore, condition 1 is satisfied.

[0148] In some other examples, if the start time unit of the fourth uplink resource is different from the start time unit of the fifth uplink resource, the end time unit of the fourth uplink resource is different from the end time unit of the fifth uplink resource, and the time domain resources occupied by the fourth uplink resource are greater than the time domain resources occupied by the fifth uplink resource, then condition 1 is satisfied. For example, as shown in FIG6D , the fourth uplink resource is resource 4 of CG1, the fifth uplink resource is resource 3 of CG2, the start symbol of resource 3 is different from the start symbol of resource 4, the end symbol of resource 3 is different from the end symbol of resource 4, but the time domain resources occupied by resource 4 are greater than the time domain resources occupied by resource 3, and therefore, condition 1 is satisfied.

[0149] (2) Condition 2: The frequency domain resources occupied by the fourth uplink resource are greater than the frequency domain resources occupied by the fifth uplink resource. In this way, the second device can reclaim the resource that occupies more frequency domain resources among the temporally overlapping resources as soon as possible, thereby improving resource utilization.

[0150] In some examples, if the starting frequency unit of the fourth uplink resource is the same as the starting frequency unit of the fifth uplink resource, and the ending frequency unit of the fourth uplink resource is after the ending frequency unit of the fifth uplink resource, then the number of frequency units included in the fourth uplink resource is greater than the number of frequency units included in the fifth uplink resource, and condition 2 is satisfied. For example, the fourth uplink resource and the fifth uplink resource are continuous in the frequency domain, the starting frequency unit of the fourth uplink resource and the starting frequency unit of the fifth uplink resource are both resource block (RB) 5, the ending frequency unit of the fourth uplink resource is RB12, and the ending frequency unit of the fifth uplink resource is RB8. In this case, condition 2 is satisfied.

[0151] In other examples, if the ending frequency unit of the fourth uplink resource is the same as the ending frequency unit of the fifth uplink resource, and the starting frequency unit of the fourth uplink resource is before the starting frequency unit of the fifth uplink resource, then the number of frequency units included in the fourth uplink resource is greater than the number of frequency units included in the fifth uplink resource, and condition 2 is satisfied. For example, the fourth uplink resource and the fifth uplink resource are continuous in the frequency domain, the starting frequency unit of the fourth uplink resource is RB5, the starting frequency unit of the fifth uplink resource is RB9, and the ending frequency unit of the fourth uplink resource and the ending frequency unit of the fifth uplink resource are both RB12. In this case, condition 2 is satisfied.

[0152] In some other examples, if the starting frequency unit of the fourth uplink resource is different from the starting frequency unit of the fifth uplink resource, the ending frequency unit of the fourth uplink resource is different from the ending frequency unit of the fifth uplink resource, and the frequency domain resources occupied by the fourth uplink resource are more than the frequency domain resources occupied by the fifth uplink resource, then the number of frequency units included in the fourth uplink resource is more than the number of frequency units included in the fifth uplink resource, and condition 2 is satisfied. For example, the fourth uplink resource and the fifth uplink resource are continuous in the frequency domain, the starting frequency unit of the fourth uplink resource is RB1, the starting frequency unit of the fifth uplink resource is RB5, the ending frequency unit of the fourth uplink resource is RB12, and the ending frequency unit of the fifth uplink resource is RB8, in this case, condition 2 is satisfied.

[0153] In another example, if the fourth uplink resource and / or the fifth uplink resource are discontinuous in the frequency domain, and the frequency domain resources occupied by the fourth uplink resource are greater than the frequency domain resources occupied by the fifth uplink resource, then condition 2 is satisfied. For example, if the RBGs occupied by the fourth uplink resource include RBG1 to RBG4 and RBG9 to RBG12, and the RBGs occupied by the fifth uplink resource include RBG9 to RBG12, then condition 2 is satisfied.

[0154] (3) Condition 3: The fourth uplink resource occupies more time-frequency domain resources than the fifth uplink resource. In this way, the second device can reclaim the resource that occupies more time-frequency domain resources among the temporally overlapping resources as soon as possible, thereby improving resource utilization.

[0155] In one possible manner, when the time domain resources occupied by the fourth uplink resource are greater than the time domain resources occupied by the fifth uplink resource, and the frequency domain resources occupied by the fourth uplink resource are greater than the frequency domain resources occupied by the fifth uplink resource, condition 3 is satisfied. For details regarding the time domain resources occupied by the fourth uplink resource being greater than the time domain resources occupied by the fifth uplink resource, refer to the description of condition 1, and for details regarding the frequency domain resources occupied by the fourth uplink resource being greater than the frequency domain resources occupied by the fifth uplink resource, refer to the description of condition 2, which will not be repeated here.

[0156] In another possible manner, the time domain resources occupied by the fourth uplink resource are greater than the time domain resources occupied by the fifth uplink resource, or the frequency domain resources occupied by the fourth uplink resource are greater than the frequency domain resources occupied by the fifth uplink resource. Furthermore, the time-frequency domain resources occupied by the fourth uplink resource are greater than the time-frequency domain resources occupied by the fifth uplink resource. In some examples, the time domain resources occupied by the fourth uplink resource are greater than the time domain resources occupied by the fifth uplink resource, and the frequency domain resources occupied by the fourth uplink resource are the same as the frequency domain resources occupied by the fifth uplink resource. For example, the fourth uplink resource occupies 5 symbols in the time domain and 4 RBs in the frequency domain; the fifth uplink resource occupies 4 symbols in the time domain and 4 RBs in the frequency domain. In this case, condition 3 is met. In other examples, the frequency domain resources occupied by the fourth uplink resource are greater than the frequency domain resources occupied by the fifth uplink resource, and the time domain resources occupied by the fourth uplink resource are the same as the time domain resources occupied by the fifth uplink resource. For example, the fourth uplink resource occupies 2 symbols in the time domain and 10 RBs in the frequency domain; the fifth uplink resource occupies 2 symbols in the time domain and 4 RBs in the frequency domain. In this case, condition 3 is satisfied. In some other examples, the time domain resources occupied by the fourth uplink resource are different from the time domain resources occupied by the fifth uplink resource, the frequency domain resources occupied by the fourth uplink resource are different from the frequency domain resources occupied by the fifth uplink resource, and the time-frequency domain resources occupied by the fourth uplink resource are more than the time-frequency domain resources occupied by the fifth uplink resource. For example, the fourth uplink resource occupies 2 symbols in the time domain and 10 RBs in the frequency domain; the fifth uplink resource occupies 4 symbols in the time domain and 4 RBs in the frequency domain. In this case, condition 3 is satisfied.

[0157] Optionally, when one of the following conditions 4 to 5 is satisfied, in the second bitmap, the second bit may also precede the third bit.

[0158] (4) Condition 4: The fourth uplink resource is used to carry the second indication information. In this way, the second device can learn as early as possible that the uplink resource carrying the second indication information is used, thereby decoding the uplink resource as early as possible and further learning the unused resources among the resources indicated by the second indication information.

[0159] 6G , the fourth uplink resource is resource 3 of CG2, and the fifth uplink resource is resource 4 of CG1. If resource 3 is used to carry the second indication information, then in the second bitmap, the second bit corresponding to the fourth uplink resource precedes the third bit corresponding to the fifth uplink resource.

[0160] In some possible approaches, condition 4 may be used alone, that is, as long as condition 4 is satisfied, the second bit precedes the third bit in the second bitmap.

[0161] In other possible embodiments, condition 4 may also be used in combination with other conditions. For example, when the time domain resources occupied by the fourth uplink resource are the same as the time domain resources occupied by the fifth uplink resource, and / or the frequency domain resources occupied by the fourth uplink resource are the same as the time domain resources occupied by the fifth uplink resource, if condition 4 is met, the second bit may precede the third bit.

[0162] Among them, if the starting time unit of the fourth uplink resource is the same as the starting time unit of the fifth uplink resource, and the ending time unit of the fourth uplink resource is the same as the ending time unit of the fifth uplink resource, then the time domain resources occupied by the fourth uplink resource are the same as the time domain resources occupied by the fifth uplink resource. For example, if the starting time unit of the fourth uplink resource and the starting time unit of the fifth uplink resource are both symbol 0, and the ending time unit of the fourth uplink resource and the ending time unit of the fifth uplink resource are both symbol 2, then the time domain resources occupied by the fourth uplink resource and the time domain resources occupied by the fifth uplink resource are the same.

[0163] There are multiple possible ways, for example, way 1 and way 2, for the frequency domain resources occupied by the fourth uplink resource and the frequency domain resources occupied by the fifth uplink resource to be the same.

[0164] Method 1:

[0165] The fourth uplink resource and the fifth uplink resource are continuous in the frequency domain. If the starting frequency unit of the fourth uplink resource is the same as the starting frequency unit of the fifth uplink resource, and the ending frequency unit of the fourth uplink resource is the same as the ending frequency unit of the fifth uplink resource, then the frequency domain resources occupied by the fourth uplink resource are the same as the frequency domain resources occupied by the fifth uplink resource. For example, if the starting frequency unit of the fourth uplink resource and the starting frequency unit of the fifth uplink resource are both RB5, and the ending frequency unit of the fourth uplink resource and the ending frequency unit of the fifth uplink resource are both RB8, then the frequency domain resources occupied by the fourth uplink resource and the frequency domain resources occupied by the fifth uplink resource are the same.

[0166] Method 2:

[0167] The fourth uplink resource and the fifth uplink resource are discontinuous in the frequency domain. The frequency domain resources occupied by the fourth uplink resource are the same as the frequency domain resources occupied by the fifth uplink resource. For example, if the frequency domain resources occupied by the fourth uplink resource and the frequency domain resources occupied by the fifth uplink resource are both: RBG0 to RBG4, and RBG9 to RBG12, then the frequency domain resources occupied by the fourth uplink resource and the frequency domain resources occupied by the fifth uplink resource are the same.

[0168] (5) Condition 5: The index of the fourth CG is less than the index of the fifth CG. In addition, the time domain resources occupied by the fourth uplink resource are the same as the time domain resources occupied by the fifth uplink resource, and / or the frequency domain resources occupied by the fourth uplink resource are the same as the time domain resources occupied by the fifth uplink resource. Among them, the time domain resources occupied by the fourth uplink resource are the same as the time domain resources occupied by the fifth uplink resource, and the specific contents of the frequency domain resources occupied by the fourth uplink resource and the time domain resources occupied by the fifth uplink resource are the same can be referred to the description in Condition 4, which will not be repeated here.

[0169] 6H , the fourth uplink resource is resource 3 of CG1, and the fifth uplink resource is resource 4 of CG2. The index of CG1 is smaller than that of CG2, so in the second bitmap, the second bit corresponding to the fourth uplink resource precedes the third bit corresponding to the fifth uplink resource.

[0170] It should be understood that when the second bit precedes the third bit in the second bitmap, the second bit and the third bit may be adjacent bits or non-adjacent bits.

[0171] In some examples, in the second bitmap, the position of the bit used to indicate resources that do not overlap in time is determined according to the start time of the resource corresponding to the bit. For example, the earlier the start time of the PUSCH resource corresponding to a certain bit, the earlier the position of the bit in the second bitmap. For example, taking Figure 6G as an example, the fourth uplink resource is resource 3 of CG2, and the fifth uplink resource is resource 4 of CG1. Resource 3 is used to transmit the second indication information. The 1st to 6th bits in the second bitmap correspond to: resource 1 of CG2, resource 2 of CG1, resource 3 of CG2, resource 4 of CG1, resource 5 of CG1 and resource 6 of CG2, respectively. At this time, in the second bitmap, the second bit and the third bit are adjacent bits, which are the 3rd bit and the 4th bit in the second bitmap, respectively.

[0172] In other examples, when one of conditions 1 to 4 is met, in the second bitmap, the bit used to indicate whether the resources of the fourth CG are used may be located before the bit used to indicate whether the resources of the fifth CG are used. For example, still taking Figure 6G as an example, the fourth uplink resource is resource 3 of CG2, and the fifth uplink resource is resource 4 of CG1. Resource 3 is used to carry the second indication information. The 1st to 6th bits in the second bitmap correspond to: resource 1 of CG2, resource 3 of CG2, resource 6 of CG2, resource 2 of CG1, resource 4 of CG1 and resource 5 of CG1, respectively. At this time, in the second bitmap, the second bit and the third bit are non-adjacent bits, which are the 2nd bit and the 5th bit in the second bitmap, respectively.

[0173] S502: The first device outputs second indication information. Correspondingly, the second device receives the second indication information.

[0174] The manner in which the first device outputs the second indication information may refer to the manner in which the first device outputs the first indication information in S302, except that the first indication information is replaced by the second indication information, which will not be described in detail here.

[0175] It can be understood that the above-mentioned second indication information can be carried in a variety of possible signaling, for example, carried in UCI, and the UCI is, for example, CG-UCI or UTO-UCI.

[0176] After receiving the second indication information, the second device can determine the usage of the first uplink resource and the second uplink resource based on the second bit and the third bit in the second indication information. The determination method can refer to S302. The second device can determine the usage of the first uplink resource and the second uplink resource based on the first bit in the first indication information, except that the first bit in the first indication information is replaced by the second bit and the third bit in the second indication information. It will not be repeated here.

[0177] Through the method shown in Figure 5, when the fourth uplink resource of the fourth CG and the fifth uplink resource of the fifth CG overlap in time, the first device can indicate through 2 bits that the fourth uplink resource and the fifth uplink resource are not used, or indicate that one of the fourth uplink resource and the fifth uplink resource is used. This method stipulates the number of bits in the second bitmap and the correspondence between each bit and the indicated resource, thereby avoiding erroneous decoding caused by the first device and the second device having inconsistent understanding of the number of bits in the second bitmap, and also avoiding erroneous decoding caused by the first device and the second device having inconsistent understanding of the correspondence between each bit and the indicated resource. In addition, through this method, the first device does not need to sort the PUSCH resources that overlap in time, thereby reducing the implementation complexity of the first device and reducing the requirements on the capabilities of the first device.

[0178] It should be understood that the method shown in FIG5 is described by taking two resources overlapping in time as an example. In actual use, the resources overlapping in time may also be more than two resources. In this case, the method shown in FIG5 is still applicable.

[0179] The following description uses as an example a fourth uplink resource, a fifth uplink resource, and a sixth uplink resource as examples of resources overlapping in time. The sixth uplink resource is a resource of the sixth CG, and the sixth uplink resource overlaps in time with at least one of the fourth uplink resource and the fifth uplink resource. Furthermore, the sixth uplink resource may or may not overlap with at least one of the fourth uplink resource and the fifth uplink resource in the frequency domain, which is not limited in this application.

[0180] For the specific content of the sixth uplink resource, and the relationship between the sixth uplink resource and the fourth uplink resource and the fifth uplink resource, please refer to the description of the third uplink resource and relationship 1 to relationship 2 in the method shown in Figure 3, except that the first uplink resource is replaced by the fourth uplink resource, the second uplink resource is replaced by the fifth uplink resource, and the third uplink resource is replaced by the sixth uplink resource. No further details will be given here.

[0181] In some examples, the second bit, the third bit, and the fourth bit in the second bitmap are used to indicate that the fourth uplink resource, the fifth uplink resource, and the sixth uplink resource are not used, or to indicate that one of the fourth uplink resource, the fifth uplink resource, and the sixth uplink resource is used. The indication method may refer to indication method one to indication method three in S501. For example, when the values ​​of the second bit, the third bit, and the fourth bit are all the first value, it indicates that one of the fourth uplink resource, the fifth uplink resource, and the sixth uplink resource is used. For another example, when the values ​​of the second bit, the third bit, and the fourth bit are all the second value, it indicates that the fourth uplink resource, the fifth uplink resource, and the sixth uplink resource are not used. For another example, when one of the fourth uplink resource, the fifth uplink resource, and the sixth uplink resource is used, the second bit may be used to indicate whether the fourth uplink resource is used, the third bit may be used to indicate whether the fifth uplink resource is used, and the fourth bit may be used to indicate whether the sixth uplink resource is used.

[0182] Optionally, in the second bitmap, the order of the second bit, the third bit, and the fourth bit may be determined based on one or more of conditions 1 to 5. Specifically, the second bit may be used to indicate whether the fourth uplink resource is used, the third bit may be used to indicate whether the fifth uplink resource is used, and the fourth bit may be used to indicate whether the sixth uplink resource is used. For example, if the time domain resources occupied by the resources are ordered from largest to smallest: the fourth uplink resource, the sixth uplink resource, and the fifth uplink resource, then in the second bitmap, the second bit precedes the fourth bit, and the fourth bit precedes the third bit. For another example, if the frequency domain resources occupied by the resources are ordered from largest to smallest: the fourth uplink resource, the sixth uplink resource, and the fifth uplink resource, then in the second bitmap, the second bit precedes the fourth bit, and the fourth bit precedes the third bit. For another example, conditions 4 and 5 may be combined. In the second bitmap, the bits corresponding to the resources carrying the second indication information precede the bits corresponding to other temporally overlapping resources. The order of the bits corresponding to other temporally overlapping resources may be determined based on condition 5. For example, as shown in Figure 6I, the fourth uplink resource is resource 4 of CG2, the fifth uplink resource is resource 5 of CG1, and the sixth uplink resource is resource 6 of CG3. Resources 4, 5, and 6 occupy the same time domain resources, resource 4 is used to transmit the second indication information, and the index of CG1 is smaller than the index of CG3. In this case, in the second bitmap, the second bit precedes the third bit, and the third bit precedes the fourth bit.

[0183] Through this example, if the fourth uplink resource of the fourth CG and the fifth uplink resource of the fifth CG overlap in time, and the sixth uplink resource of the sixth CG overlaps in time with at least one of the fourth uplink resource and the fifth uplink resource, the first device accurately indicates through multiple bits that the fourth uplink resource, the fifth uplink resource and the sixth uplink resource are not used, or indicates that one of the fourth uplink resource, the fifth uplink resource and the sixth uplink resource is used.
