Description

Technical Field

[0001] This application relates to the field of communications, and more particularly to a method for indicating resources and a communication device. Background Technology

[0002] Fifth-generation (5G) wireless communication systems utilize new radio access technology (NR). Compared to long-term evolution-advanced (LTE-A) systems, NR-based 5G systems offer greater single-carrier bandwidth and more flexible deployment frequency bands. Although commercialization of NR systems is imminent, LTE-A systems will continue to provide wireless communication services in the short term (and even the long term). Therefore, the coexistence of NR and LTE-A systems has become an important research topic.

[0003] Since the LTE-A system is still providing service, it will continue to occupy its operating frequency band (such as the band around 1.8 GHz), and the NR system can coexist with the LTE-A system by sharing spectrum. For example, if an NR system and an LTE-A system are deployed simultaneously on a certain frequency band at the same (or different) site, some time-frequency resources on that frequency band may be used by both NR network equipment and NR user equipment (UE), and also by LTE-A network equipment and LTE-A UE. When NR network equipment and NR UE use the time-frequency resources, LTE-A network equipment and LTE-A UE do not use the time-frequency resources, and vice versa.

[0004] For example, enhanced Machine Type Communication (eMTC) systems are derived from LTE-A systems. eMTC systems can operate using LTE frequency bands within LTE-A systems. To save power and reduce costs, the operating bandwidth of eMTC terminals is typically smaller than that of LTE-A systems. For instance, the operating bandwidth of an eMTC terminal can be a narrow band (NR). A NB consists of six consecutive physical resource blocks (PRBs), and a PRB consists of 12 subcarriers (SCs). When eMTC systems and NR systems coexist, the eMTC system operates on the NR frequency band. Avoiding interference between eMTC and NR systems is an important consideration.

[0005] In NR systems, there are signals that require reserved resources from LTE-A systems, such as synchronization signal blocks (SSBs) used for user-network time synchronization. In NR systems, the subcarrier spacing of the SSB can be 15kHz, 30kHz, 60kHz, 120kHz, or 240kHz, while in LTE-A systems, the SSB subcarrier spacing is only 15kHz. Correspondingly, in NR and LTE-A systems, the subcarrier spacing of the SSB differs in different frequency domains, and the symbol length in the time domain also differs.

[0006] Currently, LTE-A systems use bitmaps to indicate reserved resources. In NR systems, bitmaps are used in both the time and frequency domains to indicate reserved resources; the granularity of the time-domain bitmap is at the symbol level, while the granularity of the frequency-domain bitmap is at the resource block level. Using the bitmap method from LTE-A to indicate SSBs would lead to significant resource waste. Using the time-frequency domain bitmap method from NR to indicate SSBs would result in excessive signaling overhead. Summary of the Invention

[0007] This application provides a resource indication method and communication device to reduce resource waste and signaling overhead when indicating resources.

[0008] To address the aforementioned technical problems, this application provides the following technical solutions:

[0009] In a first aspect, embodiments of this application provide a method for indicating resources, comprising: a first communication device receiving first information sent by a second communication device, wherein the first information is used to indicate a first resource pattern and to indicate reserved resources determined by the first resource pattern, the first resource pattern being used to determine the position corresponding to each of N resource sets, where N is a positive integer greater than or equal to 1; the first communication device determining reserved resources based on the positions corresponding to the N resource sets indicated by the first resource pattern, the reserved resources being resources that the first communication device cannot use; and the first communication device determining not to transmit signals through the reserved resources. In this embodiment, after determining the reserved resources, the second communication device can obtain the first information, use the first information to indicate the first resource pattern, and also use the first information to indicate the reserved resources determined by the first resource pattern. The second communication device sending the first information to the first communication device enables the first communication device to determine the first resource pattern and indicate the reserved resources determined by the first resource pattern, and finally, the first communication device can transmit signals without using the reserved resources. In this embodiment of the application, the first information sent by the second communication device indicates the first resource pattern, and the reserved resources are determined by the positions corresponding to the N resource sets indicated by the first resource pattern. In this embodiment of the application, indicating the resource pattern can reduce resource waste and reduce the signaling overhead when indicating resources.

[0010] Secondly, embodiments of this application also provide a resource indication method, comprising: a second communication device determining reserved resources, wherein the reserved resources are resources that the second communication device indicates to a first communication device as unusable; the second communication device determining first information, wherein the first information is used to indicate a first resource pattern and to indicate the reserved resources determined by the first resource pattern, the first resource pattern being used to determine the position corresponding to each resource set in N resource sets, wherein N is a positive integer greater than or equal to 1; and the second communication device sending the first information to the first communication device. In embodiments of this application, after determining the reserved resources, the second communication device can obtain the first information, use the first information to indicate the first resource pattern, and also use the first information to indicate the reserved resources determined by the first resource pattern. The second communication device sending the first information to the first communication device enables the first communication device to determine the first resource pattern and indicate the reserved resources determined by the first resource pattern. Finally, the first communication device can transmit signals without using the reserved resources. In this embodiment of the application, the first information sent by the second communication device indicates the first resource pattern, and the reserved resources are determined by the positions corresponding to the N resource sets indicated by the first resource pattern. In this embodiment of the application, indicating the resource pattern can reduce resource waste and reduce the signaling overhead when indicating resources.

[0011] In one possible implementation of the first or second aspect, the first information includes: first indication information and second indication information, wherein the first indication information is used to indicate the first resource pattern; and the second indication information is used to indicate the reserved resources in the N resource sets indicated by the first resource pattern. The second communication device can acquire the first and second indication information. The first indication information has the following indication function: indicating the first resource pattern; and the second indication information has the following indication function: indicating the reserved resources in the N resource sets indicated by the first resource pattern. For example, if the first indication information carries the first resource pattern, the first communication device can determine the first resource pattern based on the first resource pattern carried by the first indication information. If the second indication information indicates that the reserved resources are in the N resource sets indicated by the first resource pattern, then the first communication device is instructed to determine the reserved resources configured by the second communication device in the N resource sets indicated by the first resource pattern. For example, the first and second indication information can be transmitted through different signaling, or the first and second indication information can be transmitted through the same signaling.

[0012] In one possible implementation of the first or second aspect, when the first information indicates a first state, the first resource pattern indicates a first position corresponding to the N resource sets; when the first information indicates a second state, the first resource pattern indicates a second position corresponding to the N resource sets. Here, the first position and the second position refer to different positions within the resource sets. For example, the first information has M bits, where M is an integer greater than or equal to 0. For example, if M = 1, the first state (e.g., 0) indicates that the reserved resource is at the first position corresponding to the first resource pattern (e.g., case B), and the second state (e.g., 1) indicates that the reserved resource is at the second position corresponding to the first resource pattern (e.g., case C). In this embodiment, different positions corresponding to the first resource pattern can be determined through different states of the first information. By indicating or defining different resource patterns, different positions of the reserved resources are determined, accurately defining and indicating the positions where reserved resources need to be reserved, thus avoiding conflicts caused by using the same position in the same resource set.

[0013] In one possible implementation of the first or second aspect, when the first information indicates a third state, the first resource pattern indicates a first position corresponding to the N resource sets; when the first information indicates a fourth state, the first resource pattern indicates a second position corresponding to the N resource sets; and when the first information indicates a fifth state, the first resource pattern indicates a third position corresponding to the N resource sets. The first position, second position, and third position refer to different positions within the resource sets. For example, if the number of bits in the first information is M, where M is an integer greater than or equal to 0, for example, M = 2, the third state (e.g., 00) indicates that the reserved resource is the first position corresponding to the first resource pattern (e.g., case B), the fourth state (e.g., 01) indicates that the reserved resource is the second position corresponding to the first resource pattern (e.g., case C), and the fifth state (e.g., 10) indicates that the reserved resource is the third position corresponding to the first resource pattern (e.g., case A). In this embodiment of the application, different positions corresponding to the first resource pattern can be determined by different states of the first information. By indicating or defining different resource patterns, different positions of reserved resources are determined, and the positions of the resources that need to be reserved are precisely defined and indicated, avoiding the conflict problem caused by using the same position of the same resource set.

[0014] In one possible implementation of the first or second aspect, when the first information indicates a sixth state, the first resource pattern indicates that the reserved resource does not exist in the N resource sets. The first communication device can then use this resource for signal transmission. The different states indicated by the first information can provide an indication of the existence of a reserved resource, allowing the first communication device to determine whether to use the resource indicated by the second communication device.

[0015] In one possible implementation of the first or second aspect, when the frequency range applicable to the first resource pattern is less than or equal to the first frequency value, the first position is {2, 4, 8, 10} + 14n, n = 0, where {2, 4, 8, 10} represents a value of 2, 4, 8, or 10; or, when the frequency range is greater than the first frequency value, the first position is {2, 4, 8, 10} + 14n, n = 0, 1, where {2, 4, 8, 10} represents a value of 2, 4, 8, or 10. Regarding whether the frequency range applicable to the first resource pattern is less than or equal to the first frequency value, the value of n has two possibilities. Under different values ​​of n, the value of the first position can be determined. Different values ​​of the first position represent different first resource patterns. In this embodiment, different resource patterns can be indicated, and the number of resource patterns is far less than the number of time-domain symbols, thus greatly saving signaling overhead.

[0016] In one possible implementation of the first or second aspect, when the frequency range applicable to the first resource pattern is less than or equal to the first frequency value, the first position is {2, 8} + 14n, where n = 0, and {2, 8} represents a value of 2 or 8; or, when the frequency range is greater than the first frequency value, the first position is {2, 8} + 14n, where n = 0 or 1, and {2, 8} represents a value of 2 or 8. Regarding whether the frequency range applicable to the first resource pattern is less than or equal to the first frequency value, the value of n has two possibilities. Under different values ​​of n, the value of the first position can be determined. Different values ​​of the first position represent different first resource patterns. In this embodiment, different resource patterns can be indicated, and the number of resource patterns is far less than the number of time-domain symbols, thus greatly saving signaling overhead.

[0017] In one possible implementation of the first or second aspect, the first position is {2, 16}, where {2, 16} represents a value of 2 or 16. The fixed value of the first position (2 or 16) solves the problem of inaccurate indication of the first position when the time-domain symbol length differs due to different subcarrier intervals. Each reserved resource includes M symbols in the time domain, for example, M = 10. The first symbol of the reserved resource is numbered {2, 16}, which is the symbol number within that time unit.

[0018] In one possible implementation of the first or second aspect, when the frequency range applicable to the first resource pattern is less than or equal to the first frequency value, the second position is {1, 4} + 7n, where n = 0, 1, and {1, 4} represents a value of 1 or 4; or, when the frequency range is greater than the first frequency value, the second position is {1, 4} + 7n, where n = 0, 1, 2, 3, and {1, 4} represents a value of 1 or 4. Regarding whether the frequency range applicable to the first resource pattern is less than or equal to the first frequency value, the value of n has two possibilities. Under different values ​​of n, the value of the first position can be determined. Different values ​​of the first position represent different first resource patterns. In this embodiment, different resource patterns can be indicated, and the number of resource patterns is far less than the number of time-domain symbols, thus greatly saving signaling overhead.

[0019] In one possible implementation of the first or second aspect, when the frequency range applicable to the first resource pattern is less than or equal to the first frequency value, the third position is {2, 8} + 14n, where n = 0, 1, and {2, 8} represents a value of 2 or 8; or, when the frequency range is greater than the first frequency value, the third position is {2, 8} + 14n, where n = 0, 1, 2, 3, and {2, 8} represents a value of 2 or 8. Regarding whether the frequency range applicable to the first resource pattern is less than or equal to the first frequency value, the value of n has two possibilities. Under different values ​​of n, the value of the first position can be determined. Different values ​​of the first position represent different first resource patterns. In this embodiment, different resource patterns can be indicated, and the number of resource patterns is far less than the number of time-domain symbols, thus greatly saving signaling overhead.

[0020] In one possible implementation of the first or second aspect, when the frequency range applicable to the first resource pattern is less than or equal to the first frequency value, the third position is {2, 16} + 28n, where n = 0, and {2, 16} represents a value of 2 or 16; or, when the frequency range is greater than the first frequency value, the third position is {2, 16} + 28n, where n = 0 or 1, and {2, 16} represents a value of 2 or 16. Regarding whether the frequency range applicable to the first resource pattern is less than or equal to the first frequency value, the value of n has two possibilities. Under different values ​​of n, the value of the first position can be determined. Different values ​​of the first position represent different first resource patterns. In this embodiment, different resource patterns can be indicated, and the number of resource patterns is far less than the number of time-domain symbols, thus greatly saving signaling overhead.

[0021] In one possible implementation of the first or second aspect, the first information further includes one or more of the following: periodic information, offset information, and subcarrier spacing information, wherein the periodic information is used to indicate the period value corresponding to the first resource pattern; the offset information is used to indicate the offset value of the position corresponding to each resource set; and the subcarrier spacing information is used to indicate the subcarrier spacing corresponding to each resource set. The periodic information, offset information, and subcarrier spacing information can be independent of the aforementioned first and second indication information, i.e., the periodic information, offset information, and subcarrier spacing information are transmitted through different information than the aforementioned first and second indication information. The periodic information is used to indicate the period applicable to the resource pattern corresponding to the reserved resource. Optionally, this period can be two periods, each applicable to different resource reservation situations; for example, different period values ​​can be used for SSB and coreset. The offset information is used to indicate the offset value of the position corresponding to each resource set or the offset of the first resource pattern; for example, the offset information indicates the offset value of the candidate start time position. By indicating the offset value of the location corresponding to each resource set through offset information, the offset problem caused by the misalignment of factor frame boundaries between LTE-A and NR systems can be solved, enabling precise configuration of reserved resources. Subcarrier spacing information can indicate that the subcarrier spacing is 15kHz or 30kHz. For example, if the subcarrier spacing information is 1 bit, the first state (e.g., 0) indicates a subcarrier spacing of 15kHz, and the second state (e.g., 1) indicates a subcarrier spacing of 30kHz.

The transceiver module is configured to receive first information sent by a second communication device. The first information indicates a first resource pattern and indicates reserved resources determined by the first resource pattern. The first resource pattern is used to determine the position corresponding to each of N resource sets, where N is a positive integer greater than or equal to 1. The processing module is configured to determine reserved resources based on the positions corresponding to the N resource sets indicated by the first resource pattern. The reserved resources are resources unusable by the first communication device. The processing module is configured to determine that signals will not be transmitted through the reserved resources.

For example, the first communication device may include a terminal device, and the second communication device may include a network device. Alternatively, the first communication device may include one terminal device, and the second communication device may include another terminal device. Or, the first communication device may include one network device, and the second communication device may include another network device.

[0063] In this application, transmission can be either sending or receiving. When one side of the communication is sending, the other side is receiving. TB can be either uplink or downlink transmission.

[0064] Figure 1 This diagram illustrates a possible structure of a radio access network (RAN) according to an embodiment of this application. The RAN can be a base station access system for a 2G network (i.e., the RAN includes base stations and base station controllers), a base station access system for a 3G network (i.e., the RAN includes base stations and RNCs), a base station access system for a 4G network (i.e., the RAN includes eNBs and RNCs), or a base station access system for a 5G network.

These network devices can be any device with wireless transceiver capabilities, or chips embedded within a device with specific wireless transceiver capabilities. The network devices include, but are not limited to: base stations (e.g., base stations BS, NodeB, evolved NodeB or eNB, gNodeB or gNB in ​​5G communication systems, base stations in future communication systems, access nodes, wireless relay nodes, and wireless backhaul nodes in WiFi systems). Base stations can be: macro base stations, micro base stations, pico base stations, small cells, relay stations, etc. Multiple base stations can support networks using one or more of the technologies mentioned above, or future evolved networks. The core network can support networks using one or more of the technologies mentioned above, or future evolved networks. Base stations can contain one or more co-located or non-co-located transmission receiving points (TRPs). Network devices can also be radio controllers, centralized units (CUs), or distributed units (DUs) in cloud radio access network (CRAN) scenarios. Network devices can also be servers, wearable devices, or vehicle-mounted devices, etc. The following explanation uses network devices as base stations as an example. These multiple network devices can be base stations of the same type or different types. The base station can communicate with terminal devices 1-6, or it can communicate with terminal devices 1-6 through a relay station. Terminal devices 1-6 can support communication with multiple base stations using different technologies. For example, a terminal device can support communication with a base station supporting LTE networks, or it can support communication with a base station supporting 5G networks, and it can also support dual connections with both LTE and 5G network base stations. For example, connecting the terminal to the RAN node of a wireless network. Currently, some examples of RAN nodes include: gNB, transmission reception point (TRP), evolved Node B (eNB), radio network controller (RNC), Node B (NB), base station controller (BSC), base transceiver station (BTS), home base station (e.g., home evolved Node B, or home Node B, HNB), base band unit (BBU), or wireless fidelity (Wi-Fi) access point (AP), etc.In a network architecture, network devices may include centralized unit (CU) nodes, distributed unit (DU) nodes, or RAN devices that include both CU and DU nodes.

[0066] Terminal devices 1-6, also known as user equipment (UE), mobile station (MS), mobile terminal (MT), or terminal, are devices that provide voice and / or data connectivity to users, or chips embedded within such devices. Examples include handheld devices and in-vehicle devices with wireless connectivity capabilities. Currently, some examples of terminal devices include: mobile phones, tablets, laptops, PDAs, mobile internet devices (MIDs), wearable devices, virtual reality (VR) devices, augmented reality (AR) devices, wireless terminals in industrial centers, 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, and wireless terminals in smart homes. The terminal device provided in this application embodiment may be a low-complexity terminal device and / or a terminal device in coverage enhancement A mode.

[0067] In this embodiment of the application, the base station and UE1 to UE6 form a communication system. In this communication system, the base station sends one or more of system information, RAR messages and paging messages to one or more UEs among UE1 to UE6. In addition, UE4 to UE6 also form a communication system. In this communication system, UE5 can function as a base station and can send one or more of system information, control information and paging messages to one or more UEs among UE4 and UE6.

[0068] In this embodiment, when the subcarrier spacing of the SSB is 15kHz, the SSB occupies a maximum of 4 symbols in the time domain. If the bitmap method of the LTE-A system is used to indicate valid or invalid subframes (a subframe includes 14 symbols), it will lead to serious resource waste. In addition, if the bitmap method of the time and frequency domain in the NR system is used for indication, the signaling overhead will be too large. Since the structure of the SSB is relatively fixed, there is no need to introduce excessive flexibility.

[0069] In this embodiment, the control resource set (coreset) is used to indicate the time-frequency resources used by the physical downlink control channel (PDCCH) of the NR system. In the frequency domain, all resource blocks (RBs) are divided into multiple groups of six, and a bitmap is used to indicate the usage of multiple RB groups within the entire bandwidth. The time interval can be one symbol, two consecutive symbols, or three consecutive symbols. The starting position of the PDCCH in each time slot is indicated by the base station via signaling. The coreset occupies a maximum of three symbols in the time domain. If the bitmap method of the LTE-A system is used to indicate valid or invalid subframes (a subframe includes 14 symbols), it would lead to severe resource waste. Furthermore, if the bitmap method of the time-frequency domain in the NR system is used, the signaling overhead would be too large. Since the coreset structure is relatively fixed, there is no need to introduce excessive flexibility. Therefore, this embodiment indicates reserved resources in the LTE system. These reserved resources can be used for the SSB and coreset of the NR system to achieve optimal optimization of signaling overhead and resource indication flexibility.

[0070] It is understood that, in addition to the SSB and coreset of the NR system, the reserved resources can also have other reservation types (or reservation methods). For example, the reserved resources can also be used for NR data or for ultra-reliable low latency communication (uRLLC) data. This is just an example of the reservation type of the reserved resources and is not intended to limit the embodiments of this application.

[0071] For example, the first communication device can be the aforementioned terminal device, and the second communication device can be the aforementioned network device. The second communication device can send first information to the first communication device. The first information is used to indicate a first resource pattern and to indicate a first resource determined by the first resource pattern. The first communication device receives the first information and determines the first resource based on the first information. The first resource is at least one of the following resource types: reserved resource, available resource, unavailable resource, resource requiring rate matching, resource requiring puncturing, or resource requiring discarding. Reserved resource refers to a resource reserved by the second communication device but unavailable to the first communication device. Available resource is also a non-reserved resource. Available resource is a resource indicated by the second communication device to the first communication device that the first communication device can use. Resource requiring rate matching indicates that the user needs to perform rate matching around the resource; that is, the resource is not included in the calculation of transmission resources, and the symbol should not be set on the resource during mapping. Resource requiring puncturing removes the symbol carried by the resource and does not transmit it. Punching is similar to dropping. The following example uses the first resource as a reserved resource. Please refer to [link to relevant documentation]. Figure 2 The diagram illustrates the interaction process between the first and second communication devices according to an embodiment of this application. The resource indication method provided in this embodiment will be described in detail from the perspective of the second communication device, with subsequent steps 201 to 203 described from the perspective of the first communication device. The main steps include the following:

[0072] 201. The second communication device determines the reserved resources, which are the resources that the second communication device indicates to the first communication device that are unusable.

[0073] In this embodiment of the application, the second communication device first determines the reserved resources. The second communication device determines the resources that the first communication device cannot use as the reserved resources. The reserved resources can be resources included in one or more resource sets among N resource sets. For example, the reserved resources can be determined by the position corresponding to the resource set. This position can also be called the candidate position. For example, the position corresponding to the resource set can include the candidate start time and / or the candidate frequency position.

[0074] In this embodiment of the application, a resource set includes one or more resource units. The resource unit includes a time unit, such as a symbol, time slot, subframe, frame, etc. The resource unit may also include a frequency domain unit, such as a subcarrier, resource block, narrowband, etc. The specific implementation method of the resource unit can be determined according to the application scenario.

[0075] 202. The second communication device determines first information, wherein the first information is used to indicate a first resource pattern and to indicate reserved resources determined by the first resource pattern, and the first resource pattern is used to determine the position corresponding to each resource set in N resource sets, where N is a positive integer greater than or equal to 1.

[0076] In this embodiment, after determining the reserved resources, the second communication device can determine first information and use this first information to indicate the first resource pattern. It can also use the first information to indicate the reserved resources determined by the first resource pattern. For example, the first information may be a single piece of information, which can be sent via downlink control signaling or higher-layer signaling. The first information includes one or more fields, which indicate both the first resource pattern and the reserved resources determined by the first resource pattern. Alternatively, the first information may specifically refer to multiple indications. These indications can be sent using the same information or different information; for example, one indication can be sent via higher-layer signaling, and another via downlink control information. Multiple indications can indicate both the first resource pattern and the reserved resources determined by the first resource pattern. Through the combined indication of multiple indications, the first communication device can determine both the first resource pattern and the reserved resources determined by the first resource pattern. For example, the first information may consist of two indications: the first indication indicates the first resource pattern, and the second indication indicates the resources that need to be reserved in the first resource pattern. The first instruction and the second instruction can be sent using the same information or signaling, or they can be sent using different information or signaling. For example, the first instruction can be sent using higher-level signaling, and the second instruction can be sent using downlink control information, or both the first and second instruction can be sent using downlink control information, or the first and second instruction can be sent using different information from higher-level signaling, or the first and second instruction can be sent using the same instruction information from higher-level signaling.

[0077] In this embodiment, a resource pattern can be used to determine the location corresponding to a resource set. This location may include a candidate time location and / or a frequency location. The resource pattern can be used to determine the location corresponding to a specific resource set in different scenarios. For example, the resource pattern may be case A, case B, and case C. Case A is for a scenario with a subcarrier spacing of 15kHz, while cases B and C are for a scenario with a subcarrier spacing of 30kHz. However, cases B and C are two different patterns. In this embodiment, first information can indicate a first resource pattern, which is used to determine the location corresponding to each of N resource sets, where N is a positive integer greater than or equal to 1. That is, the first resource pattern can be used to determine the location corresponding to each of one or more resource sets.

[0078] In some embodiments of this application, the first information is used to indicate a first resource pattern within a first time period and to indicate reserved resources determined by the first resource pattern. For example, the first time period is half a subframe. Additionally, the location corresponding to the resource set in this embodiment can be called a candidate location, which includes: candidate start time and candidate frequency location. For example, the location can refer to the number of the first symbol in each resource set; for example, the symbol with number 0 is the first symbol in the half-frame.

[0079] 203. The second communication device sends the first information to the first communication device.

[0080] In this embodiment of the application, the second communication device determines the reserved resources through the aforementioned step 201 and determines the first information through the aforementioned step 202. Then, the second communication device sends the first information to the first communication device. The first information can be used to indicate the first resource pattern and the reserved resources determined by the first resource pattern. For the indication method of the first information, please refer to the detailed description of the first information in the following content.

[0081] In some embodiments of this application, the first information includes: first indication information and second indication information, wherein,

[0082] The first instruction information is used to indicate the first resource pattern;

[0083] The second instruction information is used to indicate reserved resources in the N resource sets indicated by the first resource pattern.

[0084] The second communication device can acquire both first and second indication information. The first indication information has the following function: indicating a first resource pattern. The second indication information has the following function: indicating reserved resources within the N resource sets indicated by the first resource pattern. For example, if the first indication information carries the first resource pattern, the first communication device can determine the first resource pattern based on it. If the second indication information indicates reserved resources within the N resource sets indicated by the first resource pattern, then the first communication device can determine the reserved resources configured by the second communication device within those N resource sets. For example, the first and second indication information can be transmitted using different signaling methods, or they can be transmitted using the same signaling method; this is not limited here.

[0085] In some embodiments of this application, the first information further includes one or more of the following: periodic information, offset information, and subcarrier spacing information, wherein,

[0086] Periodic information is used to indicate the periodic value corresponding to the first resource pattern;

[0087] Offset information is used to indicate the offset value of the location corresponding to each resource set;

[0088] Subcarrier spacing information is used to indicate the subcarrier spacing corresponding to each resource set.

[0089] Among them, the periodic information, offset information and subcarrier spacing information can be independent of the aforementioned first indication information and second indication information, that is, the periodic information, offset information and subcarrier spacing information are transmitted with different information than the aforementioned first indication information and second indication information.

[0090] The period information is used to indicate the period applicable to the resource pattern corresponding to the reserved resources. Optionally, there can be two period information, which are applicable to different resource reservation situations. For example, different period values ​​can be used for SSB and coreset.

[0091] Offset information is used to indicate the offset value of the location corresponding to each resource set or the offset of the first resource pattern. For example, offset information indicates the offset value of the candidate start time position. By indicating the offset value of the location corresponding to each resource set, the offset problem caused by the misalignment of factor frame boundaries in LTE-A and NR systems can be solved, enabling precise configuration of reserved resources. For example, if the offset information indicates a first offset value, the first offset value can be the offset value of the first symbol number of the reserved resource. This first offset value indicates the offset value of the first symbol number of the reserved resource according to the first unit, which includes symbols, subframes, time slots, frames, etc. For example, if the first offset value indicates an offset of x symbols, then the first symbol number of the reserved resource is: mod({2, 8} + 14n + x, 70), n = 0, 1, 2, 3, or n = 0, 1. Here, mod(a, b) is a modulo operation, and the result is the remainder when a is divided by b. For example, the first symbol of a reserved resource might be numbered as: mod({2, 4, 8, 10} + 14n + x, 70), where n = 0, or n = 0, 1. Another example is: the first symbol of a reserved resource might be numbered as: mod({1, 4} + 7n + x, 70), where n = 0, 1, or n = 0, 1, 2, 3. It should be noted that symbol number 0 is the first symbol of the first subframe or the first slot within a half-frame.

[0092] The subcarrier spacing information can indicate that the subcarrier spacing is 15kHz or 30kHz. For example, if the subcarrier spacing information is 1 bit, the first state (e.g., 0) indicates that the subcarrier spacing is 15kHz, and the second state (e.g., 1) indicates that the subcarrier spacing is 30kHz. Optionally, the subcarrier spacing is the subcarrier spacing of the NR system.

[0093] 211. The first communication device receives first information sent by the second communication device, wherein the first information is used to indicate a first resource pattern and to indicate reserved resources determined by the first resource pattern, and the first resource pattern is used to determine the position corresponding to each resource set in N resource sets, where N is a positive integer greater than or equal to 1.

[0094] In the embodiments of this application, the first communication device and the second communication device can communicate with each other. For example, the first communication device can receive first information sent by the second communication device. The first information may include a single piece of information, such as downlink control signaling. The first information includes one or more fields, which indicate a first resource pattern and reserved resources determined by the first resource pattern. Alternatively, the first information may specifically refer to multiple indication information. These multiple indication information can indicate the first resource pattern and the reserved resources determined by the first resource pattern. Through the joint indication of multiple indication information, the first communication device can determine the first resource pattern and indicate the reserved resources determined by the first resource pattern.

[0095] In this embodiment, the first information may also indicate reserved resources, or the first information may also indicate reserved resources through a first resource pattern, such as indicating whether there are reserved resources in N resource sets. For example, a bitmap of 1 indicates that there are reserved resources, and a bitmap of 0 indicates that there are no reserved resources. Alternatively, the first resource pattern may be indicated by the aforementioned first indication information, and the bitmap may be used to indicate whether there are reserved resources by the aforementioned second indication information.

[0096] In this embodiment, a resource pattern can be used to determine the location corresponding to a resource set. This location may include a candidate time location and / or a frequency location. The resource pattern can be used to determine the location corresponding to a specific resource set in different scenarios. For example, the resource pattern may be case A, case B, and case C. Case A is for a scenario with a subcarrier spacing of 15kHz, while cases B and C are for a scenario with a subcarrier spacing of 30kHz. However, cases B and C are two different patterns. In this embodiment, first information can indicate a first resource pattern, which is used to determine the location corresponding to each of N resource sets, where N is a positive integer greater than or equal to 1. That is, the first resource pattern can be used to determine the location corresponding to each of one or more resource sets.

[0097] In some embodiments of this application, the first information can have at least two states: a first state and a second state. The first information uses different states to indicate different positions corresponding to the first resource pattern. For example, when the first information indicates the first state, the first resource pattern indicates the first position corresponding to N resource sets; when the first information indicates the second state, the first resource pattern indicates the second position corresponding to N resource sets. Here, the first position and the second position refer to different positions within the resource sets. For example, the first information has M bits, where M is an integer greater than or equal to 0. For example, if M = 1, the first state (e.g., 0) indicates that the reserved resource is the first position corresponding to the first resource pattern (e.g., case B), and the second state (e.g., 1) indicates that the reserved resource is the second position corresponding to the first resource pattern (e.g., case C). In the embodiments of this application, different states of the first information can determine different positions corresponding to the first resource pattern. By indicating or defining different resource patterns, different positions of reserved resources are determined, accurately defining and indicating the positions where reserved resources need to be reserved, thus avoiding conflicts caused by using the same position in the same resource set.

[0098] In some embodiments of this application, the first information may have at least three states: a third state, a fourth state, and a fifth state. The first information indicates different positions corresponding to the first resource pattern through these different states. For example, when the first information indicates the third state, the first resource pattern indicates the first position corresponding to N resource sets; when the first information indicates the fourth state, the first resource pattern indicates the second position corresponding to N resource sets; and when the first information indicates the fifth state, the first resource pattern indicates the third position corresponding to N resource sets. Here, the first position, second position, and third position refer to different positions within the resource sets. For example, if the number of bits in the first information is M, where M is an integer greater than or equal to 0, for example, if M = 2, the third state (e.g., 00) indicates that the reserved resource is the first position corresponding to the first resource pattern (e.g., case B), the fourth state (e.g., 01) indicates that the reserved resource is the second position corresponding to the first resource pattern (e.g., case C), and the fifth state (e.g., 10) indicates that the reserved resource is the third position corresponding to the first resource pattern (e.g., case A). In this embodiment of the application, different positions corresponding to the first resource pattern can be determined by different states of the first information. By indicating or defining different resource patterns, different positions of reserved resources are determined, and the positions of the resources that need to be reserved are precisely defined and indicated, avoiding the conflict problem caused by using the same position of the same resource set.

[0099] Furthermore, in some embodiments of this application, when the first information occupies two bits, the first information can also indicate a sixth state. When the first information indicates the sixth state, the first resource pattern indicates that there are no reserved resources in the N resource sets. That is, when the first information indicates the sixth state, the first resource pattern indicates that there are no reserved resources. In other words, for the first communication device, this resource can be used for signal transmission. By using different states indicated by the first information, the presence or absence of reserved resources can be indicated, allowing the first communication device to determine whether to use the resource indicated by the second communication device.

[0100] In some embodiments of this application, the first position corresponding to N resource sets can be implemented in multiple ways. For example, depending on whether the frequency range applicable to the first resource pattern exceeds a first frequency value, the value of the first position can be implemented in different ways. For example, the first frequency value can be 3GHz, but it is not limited to other frequency values. The frequency range applicable to the first resource pattern can refer to the frequency range in which the system operates. When the frequency range applicable to the first resource pattern is less than or equal to the first frequency value, the first position is {2, 4, 8, 10} + 14n, n = 0, where {2, 4, 8, 10} represents a value of 2, 4, 8, or 10; or,

[0101] When the frequency range is greater than the first frequency value, the first position is {2, 4, 8, 10} + 14n, n = 0, 1, where {2, 4, 8, 10} represents a value of 2, 4, 8, or 10.

[0102] Regarding whether the frequency range applicable to the first resource pattern is less than or equal to the first frequency value, there are two possible values ​​for n. Under different values ​​of n, the value of the first position can be determined. Different values ​​of the first position represent different first resource patterns. In this embodiment, different resource patterns can be indicated. The number of resource patterns is much smaller than the number of time domain symbols, thus greatly saving signaling overhead.

[0103] For example, each of the 8 resource sets includes 2 first time units. Taking the first resource pattern as case B, within a time unit, such as 5ms, 5 subframes, or a half-frame, there are one or more time-domain positions of reserved resources. Each reserved resource includes M symbols in the time domain. For example, M=2, and the number of the first starting symbol of the reserved resource is {2, 4, 8, 10}+14n. If the frequency range is less than or equal to 3GHz, n=0, that is, the number of the first symbol of the reserved resource is {2, 4, 8, 10}. Or, if the frequency range is greater than 3GHz and less than 6GHz, n=0, 1, that is, the number of the first symbol of the reserved resource is {2, 4, 8, 10, 16, 18, 22, 24}.

[0104] In some embodiments of this application, when the frequency range applicable to the first resource pattern is less than or equal to the first frequency value, the first position is {2, 8} + 14n, where n = 0, and {2, 8} represents a value of 2 or 8; or,

[0105] When the frequency range is greater than the first frequency value, the first position is {2, 8} + 14n, where n = 0, 1, and {2, 8} represents a value of 2 or 8.

[0106] Regarding whether the frequency range applicable to the first resource pattern is less than or equal to the first frequency value, there are two possible values ​​for n. Under different values ​​of n, the value of the first position can be determined. Different values ​​of the first position represent different first resource patterns. In this embodiment, different resource patterns can be indicated. The number of resource patterns is much smaller than the number of time domain symbols, thus greatly saving signaling overhead.

[0107] For example, each of the 8 resource sets includes 4 first time units. Taking the first resource pattern as case B, within a time unit, such as 5ms, 5 subframes, or a half-frame, there are one or more reserved resource time-domain positions. Each reserved resource includes M symbols in the time domain, for example, M=4. The number of the first starting symbol of the reserved resource is {2, 8}+14n. If the frequency range is less than or equal to 3GHz, n=0, or if the frequency range is greater than 3GHz and less than 6GHz, n=0, 1. The symbol number is the symbol number within the time unit.

[0108] In some embodiments of this application, the first position is {2, 16}, where {2, 16} represents a value of 2 or 16.

[0109] The first position is fixed at 2 or 16, which solves the problem of inaccurate indication of the first position when the time-domain symbol length is different due to different subcarrier spacing. Each reserved resource includes M symbols in the time domain, for example, M=10, and the first symbol of the reserved resource is numbered {2, 16}, which is the symbol number within that time unit.

[0110] In some embodiments of this application, when the frequency range applicable to the first resource pattern is less than or equal to the first frequency value, the second position is {1, 4} + 7n, n = 0, 1, where {1, 4} represents a value of 1 or 4; or,

[0111] When the frequency range is greater than the first frequency value, the second position is {1, 4} + 7n, where n = 0, 1, 2, 3, and {1, 4} represents a value of 1 or 4.

[0112] Regarding whether the frequency range applicable to the first resource pattern is less than or equal to the first frequency value, there are two possible values ​​for n. Under different values ​​of n, the value of the first position can be determined. Different values ​​of the first position represent different first resource patterns. In this embodiment, different resource patterns can be indicated. The number of resource patterns is much smaller than the number of time domain symbols, thus greatly saving signaling overhead.

[0113] For example, each of the 8 resource sets includes 2 first time units. Taking case C as the first resource pattern, within a time unit, such as 5ms, 5 subframes, or a half-frame, there are one or more time-domain locations of reserved resources. Each reserved resource includes M symbols in the time domain. For example, M=2. The number of the first starting symbol of the reserved resource is {1, 4}+7n. If the frequency range is less than or equal to 36Hz, n=0, 1, that is, the number of the first symbol of the reserved resource is {1, 4, 8, 11}. Or, if the frequency range is greater than 3GHz and less than 6GHz, n=0, 1, 2, 3, that is, the number of the first symbol of the reserved resource is {1, 4, 8, 11, 15, 18, 22, 25}. This symbol number is the symbol number within that time unit.

[0114] In some embodiments of this application, when the frequency range applicable to the first resource pattern is less than or equal to the first frequency value, the third position is {2, 8} + 14n, n = 0, 1, where {2, 8} represents a value of 2 or 8; or,

[0115] When the frequency range is greater than the first frequency value, the third position is {2, 8} + 14n, where n = 0, 1, 2, 3, and {2, 8} represents a value of 2 or 8.

[0116] Regarding whether the frequency range applicable to the first resource pattern is less than or equal to the first frequency value, there are two possible values ​​for n. Under different values ​​of n, the value of the first position can be determined. Different values ​​of the first position represent different first resource patterns. In this embodiment, different resource patterns can be indicated. The number of resource patterns is much smaller than the number of time domain symbols, thus greatly saving signaling overhead.

[0117] For example, each of the 8 resource sets includes 4 first time units. Taking case A as the first resource pattern, within a time unit, such as 5ms, 5 subframes, or one half-frame, there are one or more reserved resource time-domain locations. Each reserved resource includes M symbols in the time domain, for example, M=4. The first symbol of the reserved resource is numbered {2, 8}+14n. If the frequency range is greater than 3GHz and less than 6GHz, n=0, 1, 2, 3, that is, the first symbol of the 8 reserved resources is numbered {2, 8, 16, 22, 30, 36, 44, 50}. Or, if the frequency range is less than or equal to 3GHz, n=0, 1, that is, the first symbol of the 4 reserved resources is numbered {2, 8, 16, 22}. This number is the number of the symbol within that time unit.

[0118] In some embodiments of this application, when the frequency range applicable to the first resource pattern is less than or equal to the first frequency value, the third position is {2, 16} + 28n, where n = 0, and {2, 16} represents a value of 2 or 16; or,

[0119] When the frequency range is greater than the first frequency value, the third position is {2, 16} + 28n, where n = 0, 1, and {2, 16} represents a value of 2 or 16.

[0120] Regarding whether the frequency range applicable to the first resource pattern is less than or equal to the first frequency value, there are two possible values ​​for n. Under different values ​​of n, the value of the first position can be determined. Different values ​​of the first position represent different first resource patterns. In this embodiment, different resource patterns can be indicated. The number of resource patterns is much smaller than the number of time domain symbols, thus greatly saving signaling overhead.

[0121] For example, each of the 8 resource sets includes 10 first time units. Taking the first resource pattern as case A, within a time unit, such as 5ms, 5 subframes, or a half-frame, there are one or more reserved resource time-domain positions. Each reserved resource includes M symbols in the time domain, for example, M=10. The number of the first starting symbol of the reserved resource is {2, 16}+28n, the frequency is less than 3GHz, n=0, and the frequency range is greater than 3GHz and less than or equal to 6GHz, n=0, 1.

[0122] This application also provides another resource indication method, which mainly includes the following process:

[0123] The second communication device determines reserved resources, which are resources that the second communication device indicates to the first communication device are unusable, require puncture or drop, or require rate matching.

[0124] The second communication device determines first information, wherein the first information is used to indicate a first resource pattern and to indicate the reserved resources determined by the first resource pattern, the first resource pattern being used to determine the position corresponding to each resource set in N resource sets, where N is a positive integer greater than or equal to 1;

[0125] The second communication device sends the first information to the first communication device.

[0126] The first communication device receives first information sent by the second communication device, wherein the first information is used to indicate a first resource pattern and to indicate reserved resources determined by the first resource pattern, and the first resource pattern is used to determine the position corresponding to each resource set in N resource sets, where N is a positive integer greater than or equal to 1.

[0127] The first communication device determines reserved resources based on the locations corresponding to the N resource sets indicated by the first resource pattern. The reserved resources are resources that the first communication device cannot use.

[0128] The first communication device determines that it will not transmit signals through the reserved resources.

[0129] The first information includes: fifth indication information, which indicates the number of subcarriers carrying the first resource; and / or indicates that the subcarriers carrying the first resource are located at the maximum or minimum end of the subcarrier sequence.

[0130] The fifth indication information sent by the second communication device is used to indicate whether the subcarrier to be punctured is located at the little-endian or big-endian of the subcarrier number, or to indicate whether the subcarrier to be discarded is located at the little-endian or big-endian of the subcarrier number, or to indicate whether the subcarrier to be rate-matched is located at the little-endian or big-endian of the subcarrier number. For example, the fifth indication information sent by the second communication device is used to indicate whether the subcarrier to be punctured is located at the little-endian or big-endian of the resource block (RB) number, or to indicate whether the subcarrier to be discarded is located at the little-endian or big-endian of the resource block (RB) number, or to indicate whether the subcarrier to be rate-matched is located at the little-endian or big-endian of the resource block (RB) number. The little-endian refers to the side with the smaller number when sorted from smallest to largest; for example, the little-endian could be the smallest end, i.e., the smallest number. The big-endian refers to the side with the larger number when sorted from largest to smallest; for example, the big-endian could be the largest end, i.e., the largest number.

[0131] In this embodiment, the fifth indication information can also indicate the number of subcarriers that need puncturing, dropping, or rate matching. For example, if the fifth indication information is 0, it indicates that the reserved resources are on the side with the smaller subcarrier number; if the fifth indication information is 1, it indicates that the reserved resources are on the side with the larger subcarrier number. For example, 1 bit indicates whether the subcarriers that need puncturing, dropping, or rate matching are located at the largest or smallest end of the subcarrier number or RB number. For example, using 2 bits, 00 indicates that the subcarriers that need puncturing, dropping, or rate matching are in the smaller number segment, and the number of subcarriers is 1; 01 indicates that the subcarriers that need puncturing, dropping, or rate matching are in the (smallest) number segment, and the number of subcarriers is 2; 10 indicates that the subcarriers that need puncturing, dropping, or rate matching are in the (largest) number segment, and the number of subcarriers is 1; 11 indicates that the subcarriers that need puncturing, dropping, or rate matching are in the (largest) number segment, and the number of subcarriers is 2.

[0132] It is understood that, in this embodiment of the application, the second communication device sends a fifth indication message to the first communication device. The first communication device determines, based on the fifth indication message, that the N subcarriers with the smallest subcarrier numbers need to be punctured, discarded, or rate-matched, or that the N subcarriers with the largest subcarrier numbers need to be punctured, discarded, or rate-matched. That is, the fifth indication message indicates two things: the location of the subcarriers that need to be punctured, discarded, or rate-matched, and the number of subcarriers that need to be punctured, discarded, or rate-matched.

[0133] Additionally, the maximum and minimum ends can also be understood as indicating that the subcarriers that need to be punctured, dropped, or rate matched are numbered 0, 1, ... N-1, or M-1, M-2, ... MN, where N is the number of subcarriers that need to be punctured, dropped, or rate matched, and M is the number of subcarriers included in the system bandwidth or the number of subcarriers included in the narrowband.

[0134] 212. The first communication device determines the reserved resources according to the positions corresponding to the N resource sets indicated by the first resource pattern. The reserved resources are resources that the first communication device cannot use.

[0135] In this embodiment of the application, after the first communication device receives the first information, the first communication device can parse the first information, determine the first resource pattern indicated by the first information, and further determine the first resource pattern and the positions corresponding to the N resource sets indicated by the first resource pattern. By determining the positions corresponding to the N resource sets indicated by the first resource pattern, the reserved resources configured by the second communication device are determined. Then the first communication device cannot use the reserved resources. For the indication method of the first information, please refer to the detailed description of the first information in the foregoing content.

[0136] 213. The first communication device determines that it will not transmit signals through the reserved resources.

[0137] In this embodiment of the application, after the first communication device determines the reserved resource indicated by the second communication device, the first communication device can determine that the reserved resource cannot be used to transmit a signal. The signal includes one or more of the following signals: physical uplink channel, physical downlink channel, reference signal, physical uplink control channel, physical downlink control channel, cell reference signal, sounding reference signal, and demodulation reference signal.

[0138] It should be noted that in some other embodiments of this application, if the first communication device determines that the resource is available, the first communication device can use the available resource for signal transmission, wherein the signal includes one or more of the following signals: physical uplink channel, physical downlink channel, reference signal, physical uplink control channel, physical downlink control channel, cell reference signal, probe reference signal, demodulation reference signal.

[0139] In some embodiments of this application, the first information is also used to indicate that reserved resources are used for synchronization signal blocks or control resource sets. That is, the reservation method (or type) of the reserved resources can be for synchronization signal blocks or for control resource sets.

[0140] In some embodiments of this application, when the first information indicates the third state, the first resource pattern indicates the first resource reservation type and indicates the first position corresponding to N resource sets;

[0141] When the first information indicates the fourth state, the first resource pattern indicates the first resource reservation type and indicates the second position corresponding to the N resource sets;

[0142] When the first information indicates the fifth state, the first resource pattern indicates the second resource reservation type;

[0143] When the first information indicates the sixth state, the first resource pattern indicates that there are no reserved resources in the N resource sets.

[0144] The first resource reservation type can be used for synchronization signal blocks, and the second resource reservation type can be used for control signal sets. For example, when the first resource pattern indicates the first position corresponding to N resource sets, the first resource pattern can be the aforementioned case B. When the first resource pattern indicates the second position corresponding to N resource sets, the first resource pattern can be the aforementioned case C.

[0145] In some embodiments of this application, when the first information indicates the third state, the first resource pattern indicates the first resource reservation type and indicates the first position corresponding to N resource sets;

[0146] When the first information indicates the fourth state, the first resource pattern indicates the first resource reservation type and indicates the second position corresponding to the N resource sets;

[0147] When the first information indicates the fifth state, the first resource pattern indicates the second resource reservation type;

[0148] When the first information indicates the sixth state, the first resource pattern indicates the first resource reservation type and indicates the third position corresponding to the N resource sets.

[0149] The first resource reservation type can be used for synchronization signal blocks, and the second resource reservation type can be used for control signal sets. For example, when the first resource pattern indicates a first position corresponding to N resource sets, the first resource pattern can be the aforementioned case B. When the first resource pattern indicates a second position corresponding to N resource sets, the first resource pattern can be the aforementioned case c. When the first resource pattern indicates a third position corresponding to N resource sets, the first resource pattern can be the aforementioned case A.

[0150] As illustrated by the foregoing embodiments, in this application embodiment, after determining the reserved resources, the second communication device can obtain first information and use this first information to indicate a first resource pattern. It can also use the first information to indicate the reserved resources determined by the first resource pattern. The second communication device sends this first information to the first communication device, enabling the first communication device to determine the first resource pattern and indicate the reserved resources determined by the first resource pattern. Finally, the first communication device can transmit signals without using the reserved resources. In this application embodiment, the first information sent by the second communication device indicates the first resource pattern and also determines the reserved resources based on the positions corresponding to the N resource sets indicated by the first resource pattern. Indicating the resource pattern in this application embodiment can reduce resource waste and signaling overhead when indicating resources.

[0151] To facilitate a better understanding and implementation of the above-described solutions in the embodiments of this application, specific examples of corresponding application scenarios are provided below.

[0152] In this embodiment, resources can be reserved for SSB and coreset indications in the LTE system to achieve an optimal trade-off between signaling overhead and resource indication flexibility. This embodiment can use a bitmap to indicate whether there is an SSB at multiple candidate locations, while also indicating the subcarrier spacing used by the NR system, and whether the SSB resource pattern is case B or case C when the subcarrier spacing is 30kHz. Furthermore, this embodiment indicates the resource pattern for reserving resources in the time domain when indicating different cases. In this embodiment, the network device can also indicate whether the reserved resources are for SSB or coreset. This embodiment indicates the number of symbols to be reserved, the starting position within a subframe, and the period for coreset indication.

[0153] In this embodiment, the first device can be a network device, and the second device can be a terminal device. Alternatively, the second device can be a network device, and the first device can be a terminal device. Alternatively, the first device can be a device with transmitting capabilities, and the second device can be a device with receiving capabilities. The following embodiments use a network device as the first device and a terminal device as the second device as an example. In this embodiment, the interaction process between the network device and the terminal device mainly includes the following steps:

[0154] Step 1: The network device determines the first information and / or the second information.

[0155] Step 2: The network device sends the first information and / or the second information to the terminal device.

[0156] The first and second information are used to indicate reserved resources, available resources, unavailable resources, or resources that require rate matching.

[0157] Specifically, the first information includes one or more of the following: first type indication information, periodic information, second type indication information, first offset value, and subcarrier spacing information.

[0158] The first type of indication information is used to indicate whether there are reserved resources or whether L (L=4 or 8) reserved resource units need to be reserved, or the second type of indication information indicates whether L reserved resource units in the SSB drawing need to be reserved.

[0159] The period information is used to indicate the period to which the reserved resource pattern applies. The optional period can be two period information (SSb and coreset), which are applicable to different resource reservation situations.

[0160] The second type of instruction information is used to indicate the SSB or reserved resource pattern or to indicate that the reserved resource is one or more of the following: the first case (such as SSB case B), the second case (such as SSB case C), the third case (such as SSB case A), or no reservation is required.

[0161] Optionally, as shown in Table 1 below, the subcarrier spacing information indicates that the subcarrier spacing is 15kHz or 30kHz. For example, this indication information is 1 bit. The first state (e.g., 0) indicates that the subcarrier spacing is 15kHz or a multiple of 1, and the second state (e.g., 1) indicates that the subcarrier spacing is 30kHz or a multiple of 2. Optionally, this subcarrier spacing is the subcarrier spacing of the NR system.

[0162] Subcarrier spacing information Instructions First state (e.g., 0) First subcarrier spacing (e.g., 15 kHz) Second state (e.g., 1) Second subcarrier spacing (e.g., 30kHz)

[0163] Optionally, the second type indicates that the number of bits of information is M, where M is an integer greater than or equal to 0.

[0164] As shown in Table 2 below, for example, M=1, the first state (e.g., 0) indicates that the reserved resources are in the first case (e.g., case B), the second state (e.g., 1) indicates that the reserved resources are in the second case (e.g., case C). Optionally, when the subcarrier spacing information indicates the second subcarrier spacing, or indicates that the subcarrier spacing is 30KHz, or indicates that the subcarrier spacing of the second system is 30kHz, M=1; otherwise, M--0.

[0165] The second type of instruction information Instructions First state (e.g., 0) Reserved resources for the first case (e.g., case B or SSB is case B). Second state (e.g., 1) Reserve resources for a second scenario (e.g., case C or SSB is case C).

[0166] For example, when M=2, the first state (e.g., 00) indicates that no reservation is needed; the second state (e.g., 01) indicates reservation case one (e.g., case A or SSB is case A); the third state (e.g., 10) indicates reservation case two (e.g., case B or SSB is case B); and the fourth state (e.g., 11) indicates reservation case three (e.g., case C or SSB is case C). Optionally, the first state (e.g., 00) indicates reservation case one (e.g., case A or SSB is case A); the second state (e.g., 01) indicates reservation case two (e.g., case B or SSB is case B); and the third state (e.g., 10) indicates reservation case three (e.g., case C or SSB is case C).

[0167] Optionally, the above-mentioned reserved resource case 1, or case A, or SSB, refers to the temporal location of one or more candidate reserved resources within a time unit, such as 5ms, 5 subframes, or one half-frame. Each reserved resource includes M symbols in the temporal domain. For example, if M=4, the first starting symbol of the candidate reserved resource is numbered {2, 8}+14n, where n=0, 1, 2, 3. That is, the first symbol of the 8 reserved resources is numbered {2, 8, 16, 22, 30, 36, 44, 50}. Alternatively, n=0, 1, meaning the first symbol of the 4 reserved resources is numbered {2, 8, 16, 22}. This number is the symbol's number within that time unit. Figure 3 The diagram shown illustrates the location of the first starting symbol for reserved resources in an embodiment of this application. The shaded squares represent reserved resources when n = {0, 1, 2, 3}, with each small square representing a symbol. The terminal device can determine its frequency range based on its operating bandwidth. Optionally, when the frequency range is less than or equal to 3GHz, n = 0, 1; when the frequency range is greater than 3GHz and less than or equal to 6GHz, n = 0, 1, 2, 3.

[0168] like Figure 4 The diagram shown illustrates another possible location of the first starting symbol for the reserved resources in an embodiment of this application. Optionally, in the first scenario of reserved resources, M = 10, the number of the first starting symbol for the reserved resources is {2, 16} + 28n, the frequency is less than 3GHz, n = 0, the frequency range is greater than 3GHz and less than or equal to 6GHz, and the frequency n = 0, 1.

[0169] Optionally, the above-mentioned reserved resource scenario two, or case B, or SSB, refers to the temporal location of one or more candidate reserved resources within a time unit, such as 5ms, 5 subframes, or one half-frame. Each reserved resource includes M symbols in the temporal domain. For example, if M=2, the first symbol of the reserved resource is numbered {2, 4, 8, 10}+14n, where n=0, meaning the first symbol of the reserved resource is numbered {2, 4, 8, 10}, or n=0, 1, meaning the first symbol of the reserved resource is numbered {2, 4, 8, 10, 16, 18, 22, 24}. This symbol number is the symbol number within that time unit. Figure 5 The diagram shown illustrates another possible location for the first starting symbol of the reserved resources in an embodiment of this application. The shaded squares represent reserved resources when n = {0, 1}, with each small square representing one symbol. Optionally, when the frequency range is less than or equal to 3 GHz, n = 0; when the frequency range is greater than 3 GHz and less than or equal to 6 GHz, n = 0, 1.

[0170] like Figure 6The diagram shown illustrates another possible location for the first starting symbol of the reserved resources in an embodiment of this application. Optionally, in the second reserved resource scenario, M = 4, the number of the first starting symbol of the reserved resources is {2, 8} + 14n, where n = 0, or n = 0, 1. This symbol number is the symbol number within that time unit.

[0171] like Figure 7 The diagram shown illustrates another possible location for the first starting symbol of the reserved resources in an embodiment of this application. Optionally, in the second reserved resource scenario, M = 10, the first symbol number of the reserved resources is {2, 16}, and this symbol number is the symbol number within that time unit.

[0172] Optionally, the above-mentioned reserved resource case three, or case C, or SSB, where case C is the temporal location of one or more (candidate) reserved resources within a time unit, such as 5ms, 5 subframes, or one half-frame, and each reserved resource includes M symbols in the temporal domain, for example, M=2, the first starting symbol of the reserved resource is numbered {1, 4}+7n, n=0, 1, that is, the first symbol of the reserved resource is numbered {1, 4, 8, 11}, or n=0, 1, 2, 3, that is, the first symbol of the reserved resource is numbered {1, 4, 8, 11, 15, 18, 22, 25}, and this symbol number is the symbol number within that time unit. Figure 8 The diagram shown illustrates another possible location for the first starting symbol of the reserved resources in an embodiment of this application. The shaded squares represent reserved resources when n = {0, 1, 2, 3}, with each small square representing one symbol. Optionally, when the frequency range is less than or equal to 3 GHz, n = 0, 1; when the frequency range is greater than 3 GHz and less than or equal to 6 GHz, n = 0, 1, 2, 3.

[0173] Optionally, the number of bits for the first type of indication information is P, where P is an integer greater than or equal to 1, specifically, P = 8, P = 4, or P = 2. For example, if P = 8, when the frequency range is greater than 3 GHz and less than or equal to 6 GHz, the 8 bits indicate one or more of the above-mentioned reserved resource conditions one to three. For example, a bit of 1 indicates that the reserved resource at the corresponding location needs to be reserved or is unavailable, and a bit of 0 indicates that the reserved resource at the corresponding location does not need to be reserved or is available. When the frequency range is less than or equal to 3 GHz, the first 4 bits of the 8 bits are used to indicate the reservation status of the reserved resource at the corresponding location, or in this case, P = 4.

[0174] For example, in case A, the first symbol has 8 reserved resources and 8 bits numbered {2, 8, 16, 22, 30, 36, 44, 50}. Figure 1In a one-to-one correspondence, a bit of 1 indicates that the reserved resource at the corresponding position needs to be reserved or is unavailable, while a bit of 0 indicates that the reserved resource at the corresponding position does not need to be reserved or is available. For example... Figure 9 The diagram shown illustrates another possible location for the first starting symbol of the reserved resource in an embodiment of this application. For example, when the first type of indication information is 10101101, 1 represents a reserved resource and 0 represents a non-reserved resource.

[0175] For case B, the first symbol has 8 reserved resources and 8 bits numbered {2, 4, 8, 10, 16, 18, 22, 24}. Figure 1 In a one-to-one correspondence, a bit of 1 indicates that the reserved resource at the corresponding position needs to be reserved or is unavailable, while a bit of 0 indicates that the reserved resource at the corresponding position does not need to be reserved or is available. For example... Figure 10 The diagram shown illustrates another possible location for the first starting symbol of the reserved resource in an embodiment of this application. For example, when the first type indication information is 10110110, 1 represents a reserved resource and 0 represents a non-reserved resource.

[0176] Optionally, the number of bits for the first type of indication information is P. When the frequency range is less than or equal to 3 GHz, P = 4; when the frequency range is greater than 3 GHz and less than or equal to 6 GHz, P = 8. Alternatively, the first type of indication information can be a long bitmap or a short bitmap, with the long bitmap having more bits than the short bitmap. For example, the long bitmap has a length of 8 bits, and the short bitmap has a length of 4 bits.

[0177] Optionally, the first offset value indicates the offset value of the first symbol number of the reserved resource. This first offset value indicates the offset value of the first symbol number of the reserved resource according to a first unit, which includes symbols, subframes, time slots, frames, etc. For example, if the first offset value indicates an offset of x symbols, then the first symbol number of the reserved resource is:

[0178] Reserved resource scenario 1: mod({2, 8} + 14n + x, 70), n = 0, 1, 2, 3, or n = 0, 1. Here, mod(a, b) is the modulo operation, and the result is the remainder when a is divided by b.

[0179] Option 2 for reserving resources: mod({2, 4, 8, 10} + 14n + x, 70), n = 0, or n = 0, 1.

[0180] Option 3 for reserving resources: mod({1, 4} + 7n + x, 70), n = 0, 1, or n = 0, 1, 2, 3.

[0181] It should be noted that the symbol number 0 is the first symbol of the first subframe or the first s1ot in a half-frame.

[0182] Optionally, in the aforementioned reserved resources, the result of the cyclic shift of the number of the first symbol of the reserved resource can also be used for the position of the reserved resource. For example, reserved resource case one: mod({2, 8}+14n+x, 70), n=0, 1, 2, 3, or n=0, 1. Here, mod(a, b) is the modulo operation, and the result is the remainder when a is divided by b.

[0183] Option 2 for reserving resources: mod({2, 4, 8, 10} + 14n + x, 70), n = 0, or n = 0, 1.

[0184] Option 3 for reserving resources: mod({1, 4} + 7n + x, 70), n = 0, 1, or n = 0, 1, 2, 3.

[0185] Where x is an integer greater than or equal to 0. It should be noted that the above formula is only one way of describing the result; other expressions can also be used, such as tables, mapping curves, etc., as long as the result is the same.

[0186] Optionally, the base station also sends a fourth type of indication information, which is used to indicate the number of symbols Q occupied by the reserved resources, where Q is an integer greater than or equal to 1, such as Q = 1, 2, or 3.

[0187] Optionally, the base station also sends a fifth type of indication information. The fifth type of indication information uses a bitmap to indicate the starting position of the first symbol of the reserved resource. For example, 14 bits are used to indicate the position number of the first symbol of the reserved resource in a subframe (the number of symbols in a subframe is 14). For example, if the fourth type of indication information indicates that the reserved resource occupies 3 symbols, and the fifth type of indication information is 10010010000000, it means that there are three reserved resources in the subframe, and the positions of the first symbols are the symbols numbered 0, 3, and 6 respectively. The length of each reserved resource is 3 symbols.

[0188] Optionally, the second information is used to indicate whether the resource is a reserved resource or an available resource.

[0189] Optional, Figure 11 This is a schematic diagram illustrating the indication of subcarrier numbers in an embodiment of this application. The base station also sends a sixth type of indication information, used to indicate whether the subcarriers requiring puncture, drop, or rate matching are located at the largest or smallest end of the subcarrier number or RB number, and / or to indicate the number of subcarriers requiring puncture, drop, or rate matching. For example, 0 indicates that reserved resources are on the side with smaller subcarrier numbers, and 1 indicates that reserved resources are on the side with larger subcarrier numbers.

[0190] Step 3: The terminal device receives the first and / or second information sent by the network device.

[0191] Step 4: The terminal device determines the first information and / or the second information, and reserves or uses the corresponding resources to send and receive information based on the first information and / or the second information. For details, please refer to the explanation in Step 2.

[0192] The solution implemented in this application can effectively avoid resource conflicts with SSB and coreset. At the same time, it indicates the type of reserved resources based on the characteristics of SSB and coreset. Compared with the time-domain bitmap method, it saves signaling overhead. The granularity of reserved resources is at the symbol level, thus avoiding resource waste.

[0193] The bitmap method of the LTE-A system indicates valid or invalid subframes (a subframe includes 14 symbols). In the embodiments of this application, the resource pattern indicating SSB or coreset is a symbol-level resource reservation.

[0194] The NR system uses a bitmap method in the time-frequency domain, while the embodiment of this application combines SSB and coreset resource pattern design signaling to indicate different resource patterns. The number of resource patterns is much smaller than the number of time-domain symbols, which greatly saves signaling overhead.

[0195] In this embodiment, a bitmap is used to indicate whether an SSB exists at any of the eight candidate locations, and simultaneously to indicate the subcarrier spacing used by the NR system and whether the SSB resource pattern is case B or case C when the subcarrier spacing is 30kHz. This embodiment uses symbol-level resource reservation, further conserving resources.

[0196] In this application embodiment, different resource patterns for reserved resources are indicated or defined for different scenarios. Since the SCS of NR and LTE may be different, and the frame boundaries may be misaligned, indicating or defining different resource patterns can determine the location of the reserved resources of SSB, accurately define and indicate the location of the resources that need to be reserved, and avoid the collision problem between LTE and SSB.

[0197] In this embodiment, the network device can indicate whether the reserved resources are intended for use as SSB or corset. This is used to distinguish different indication signaling and avoid signaling confusion and waste.

[0198] In this embodiment, the coreset indicates the number of symbols to be reserved, the starting position within a subframe, and the period. This embodiment uses symbol-level resource reservation to save resources.

[0199] In some embodiments of this application, such as Figure 12The diagram shown is a schematic diagram of an indication of the starting position and time length provided in an embodiment of this application. The first information includes a first indication value, which is used to indicate the starting position of the first resource and the number of time units included in the first time unit.

[0200] The first indication value Q and the number Q of time units included in the first time unit satisfy the following relationship:

[0201] When (L-1) < floor(N / 2), Q = N(L-1) + Tstart;

[0202] When (L-1)≥floor(N / 2), Q=N(N-L+1)+(N-1-Tstart);

[0203] Wherein, L is the length of the first resource, Tstart is the starting position of the first resource within the first time unit, and floor represents rounding down.

[0204] The first information includes a first indication value, which indicates the starting position and second time length of the resources to be reserved within the first time unit. The starting position can be the starting position of a symbol / time slot, and the second time length can be the number of symbols / time slots. The first time unit can be a subframe, a frame, or N frames (N is an integer greater than or equal to 0). Optionally, the first indication value is used to indicate the starting point in the time domain and the length of continuous time in the time domain. If the first time unit (e.g., a subframe) contains N second time units (e.g., symbols, N=14), then the first indication value Q satisfies the above relationship.

[0205] Optionally, the first information also includes second indication information, which indicates the time-domain pattern of the reserved resources determined by the first indication value, or a time-domain resource pattern in units of a first time unit. For example... Figure 13 The diagram shown is another schematic diagram indicating the start position and time length in an embodiment of this application. For example, the bit map corresponding to the resource pattern is 1010100101. For example, the bit map method can be used to indicate that 1 indicates that the resources in the first time unit in the time domain are reserved according to the resource reservation method indicated by the first indication information, and 0 indicates that no reservation is required in the time domain.

[0206] It should be noted that, for the sake of simplicity, the foregoing method embodiments are all described as a series of actions. However, those skilled in the art should understand that this application is not limited to the described order of actions, as some steps may be performed in other orders or simultaneously according to this application. Furthermore, those skilled in the art should also understand that the embodiments described in the specification are preferred embodiments, and the actions and modules involved are not necessarily essential to this application.
