Description

Technical Field

[0001] This application relates to the field of communication technology, and in particular to a communication method and apparatus. Background Technology

[0002] In cellular communication systems, terminal devices communicate with network devices based on cells. As a terminal device moves from the signal coverage area of ​​one cell to the signal coverage area of ​​another cell, the signal strength of the other cell is stronger for that terminal device, and the network device can instruct the terminal device to switch to the other cell.

[0003] Specifically, the terminal device measures the reference signals corresponding to the reference signal resources of one or more candidate cells to obtain the signal quality of each candidate cell. When the terminal device finds that the signal quality of a candidate cell is stronger than the signal quality of its serving cell, the terminal device can report the measurement results to the network device. Then, the network device sends a cell handover signaling to the terminal device based on the measurement results. The cell handover signaling instructs the terminal device to hand over to a target candidate cell. This target candidate cell is one of the terminal device's candidate cells. The terminal device hands over to the target candidate cell according to the cell handover signaling.

[0004] However, how network devices configure the reference signal resources of candidate cells for terminal devices so that terminal devices can better measure the reference signal resources is a question worth considering. Summary of the Invention

[0005] This application provides a communication method and apparatus for configuring reference signal resources for candidate cells. This facilitates terminal devices in better measuring the signal quality of each candidate cell and providing corresponding measurement results to network devices. It also enables network devices to instruct terminal devices to switch to suitable candidate cells, thereby improving communication transmission performance.

[0006] The first aspect of this application provides a communication method applied to a first communication device, which is a terminal device or a device applied to a terminal device. For example, it may be a chip, chip system, module, processing unit, control unit, or circuit used in the terminal device; specific details are not limited in this application. It should be noted that, in this application, when referring to a terminal device, it can refer to the terminal device itself, or it can be replaced by a chip, functional module, or integrated circuit within the terminal device that performs the method provided in this application; specific details are not limited in this application. The method includes: a first communication device receiving a reference signal resource configuration, the reference signal resource configuration indicating a first reference signal resource group, the first reference signal resource group including some or all reference signal resources of P candidate cells, where P is a positive integer; the first reference signal resource group satisfying at least one of the following: when the first reference signal resource group includes the first reference signal resource of a first candidate cell, the first reference signal resource group includes all reference signal resources in the reference signal resource set where the first reference signal resource is located, and the first candidate cell is one of the P candidate cells; when the first reference signal resource group includes the first reference signal resource of a first candidate cell, the first reference signal resource group includes all reference signal resources of the first candidate cell; or, when the first reference signal resource group includes the reference signal resources of multiple candidate cells, the first configuration parameters corresponding to the reference signal resources of the multiple candidate cells are the same, and the multiple candidate cells are some or all of the P candidate cells; the first communication device sending a measurement result, the measurement result being the measurement result corresponding to the first reference signal resource group.

[0007] In the above technical solution, the first communication device receives reference signal resource configuration. The reference signal resource configuration is used to indicate a first reference signal resource group, which includes some or all reference signal resources of P candidate cells, where P is a positive integer. The first communication device sends measurement results, which are the measurement results corresponding to the first reference signal resource group. Therefore, it can be seen that the first communication device receives the reference signal resource configuration. The reference signal resource configuration is used to indicate the first reference signal resource group, which includes some or all reference signal resources of P candidate cells. This enables the configuration of reference signal resources for candidate cells for the first communication device. Furthermore, the above solution defines the configuration constraints of the reference signal resources in the first reference signal resource group. This facilitates the terminal device in better measuring the signal quality of each candidate cell and providing corresponding measurement results to the network device, making it easier for the network device to instruct the terminal device to switch to a suitable candidate cell, thereby improving communication transmission performance. Furthermore, this solution facilitates the network device in managing the reference signal resources of candidate cells. For example, when the first reference signal resource group includes the first reference signal resource of the first candidate cell, the first reference signal resource group includes all reference signal resources in the reference signal resource set where the first reference signal resource is located. Therefore, the first reference signal resource group includes all reference signal resources in the entire reference signal resource set. Reference signal resources in the reference signal resource set often correspond to the same wide beam, while each reference signal resource in the set corresponds to a narrow beam. Different reference signal resources can correspond to different narrow beams. The narrow beam corresponding to each reference signal resource in the reference signal resource set is located within the wide beam. The network device configures the terminal device to measure the reference signal resources in the entire reference signal resource set. This avoids missing the measurement of some important beams. The terminal device can obtain the signal quality of each beam of the candidate cell and report it to the network device. This allows the network device to instruct the terminal device to switch to a suitable candidate cell based on the measurement results, thereby improving communication transmission performance. For example, when the first reference signal resource group includes the first reference signal resource of the first candidate cell, the first reference signal resource group includes all reference signal resources of the first candidate cell. Each reference signal resource corresponds to a narrow beam, and the network device configures the terminal device to measure all reference signal resources of the first candidate cell. This avoids missing the measurement of some important beams of the first candidate cell. The terminal device can obtain the signal quality of each beam of the first candidate cell and report it to the network device. This allows the network device to instruct the terminal device to switch to a suitable candidate cell based on the measurement results, thereby improving communication transmission performance. For example, when the first reference signal resource group includes reference signal resources from multiple candidate cells, and the reference signal resources of these multiple candidate cells correspond to the same first configuration parameters, it facilitates the network device's management of the reference signal resources from multiple candidate cells.Furthermore, the first configuration parameters corresponding to the reference signal resources of multiple candidate cells facilitate fair measurement of multiple candidate cells by the terminal device, avoiding some candidate cells occupying a large amount of measurement resources while others occupy almost no measurement resources. This allows the network device to instruct the terminal device to switch to a suitable candidate cell, thereby improving communication transmission performance.

[0008] Based on the first aspect, in one possible implementation, the first configuration parameter includes at least one of the following: reference signal resource type, transmission period of the reference signal corresponding to the reference signal resource, transmission power, scrambling identifier for generating the sequence of the reference signal corresponding to the reference signal resource, subcarrier spacing used for transmitting the reference signal corresponding to the reference signal resource, or cyclic redundancy prefix (CP); wherein, the reference signal resource type includes periodic resources, semi-persistent resources, or aperiodic resources. This implementation provides the specific content included in the first configuration parameter. For example, having the same reference signal resource type, transmission period, and transmission power for multiple candidate cells helps ensure fair measurement of multiple candidate cells by the terminal device. Another example is having the same scrambling identifier for each of the multiple candidate cells, which helps ensure orthogonality of the reference signals corresponding to each of the multiple candidate cells, facilitating the terminal device to distinguish the reference signals corresponding to each of the multiple candidate cells. Yet another example is having the same subcarrier spacing for each of the multiple candidate cells, ensuring frequency domain granularity alignment of the reference signals corresponding to the multiple candidate cells. And yet another example is having the same CP for each of the multiple candidate cells, ensuring synchronization of the reference signals of the multiple candidate cells.

[0009] Based on the first aspect, in one possible implementation, the method further includes: a first communication device receiving a reporting configuration, the reporting configuration being a reporting configuration associated with a reference signal resource configuration, the reporting configuration indicating at least one of the following: the number L of candidate cells to be reported, or the reporting content included in the measurement results of each candidate cell to be reported, the reporting content including information on M reference signal resources of the candidate cells to be reported; the information on each reference signal resource including the index of the reference signal resource and / or signal quality, where L and M are both positive integers. In this implementation, the first communication device receiving the reporting configuration facilitates the first communication device reporting the measurement results of the candidate cells based on the reporting configuration.

[0010] Based on the first aspect, in one possible implementation, the method further includes: a first communication device receiving configuration information, the configuration information being used to indicate the reference signal resources of each candidate cell among P candidate cells. In this implementation, the first communication device receives the reference signal resources of each candidate cell configured by the network. This facilitates the first communication device in knowing the specific configuration of the reference signal resources in the first reference signal resource group, and facilitates the measurement and reporting of the reference signal resources of the candidate cells.

[0011] Based on the first aspect, in one possible implementation, the configuration information is used to indicate the reference signal resources of each candidate cell among the P candidate cells, including: the configuration information is used to indicate at least one set of reference signal resources corresponding to each candidate cell among the P candidate cells, and each set of reference signal resources includes one or more reference signal resources.

[0012] In this implementation, each candidate cell is configured with one or more corresponding sets of reference signal resources. This facilitates the management of reference signal resources and reduces the complexity of terminal equipment measuring these resources. For example, the network can be configured to allow terminal equipment to measure reference signal resources within the entire set. Since the terminal equipment can measure all reference signal resources in the set, it does not need to select specific reference signal resources from the set and then measure those selected resources. This further reduces the complexity of reference signal resource measurement for the terminal equipment.

[0013] Based on the first aspect, in one possible implementation, the reference signal resources in the first reference signal resource group are semi-persistent reference signal resources. The method further includes: a first communication device receiving a first activation signaling, which is used to activate the reference signal resources in the first reference signal resource group. In this implementation, the first activation signaling activates the reference signal resources at the reference signal resource group level. This is beneficial for improving the activation efficiency of the reference signal resources and reducing the activation signaling overhead.

[0014] Based on the first aspect, in one possible implementation, the first activation signaling includes at least one of the following: an index of the first reference signal resource group, an index of the reference signal resource configuration to which the first reference signal resource group belongs, or an index of the reporting configuration associated with the reference signal resource configuration to which the first reference signal resource group belongs. This facilitates the first communication device to measure the reference signal resources in the first reference signal resource group based on the first activation signaling and to report the corresponding measurement results.

[0015] Based on the first aspect, in one possible implementation, the method further includes: a first communication device receiving a second activation signaling, the second activation signaling being used to activate a reference signal resource set of one of the P candidate cells. In this implementation, the second activation signaling activates reference signal resources at the granularity of the reference signal resource set. This is beneficial for improving the activation efficiency of reference signal resources and reducing activation signaling overhead.

[0016] Based on the second aspect, in one possible implementation, the second activation signaling includes at least one of the following: an index of the reference signal resource set, or an index of the candidate cell.

[0017] Based on the first aspect, in one possible implementation, the reference signal resources included in the first reference signal resource group belong to a set of Q reference signal resources, where Q is an integer greater than or equal to 2, and the set of Q reference signal resources corresponds one-to-one with the Q second activation signaling.

[0018] Q second activation signaling messages are carried in the same downlink signaling; or, Q second activation signaling messages occupy the same time domain resources; or, the time domain resources occupied by Q second activation signaling messages are located in the same time period.

[0019] In this implementation, the reference signal resources of the first reference signal resource group belong to Q sets of reference signal resources. The network can activate these Q sets of reference signal resources through Q second activation signaling. Furthermore, it limits the activation of the Q sets of reference signal resources to either simultaneous activation or activation within a certain time period, avoiding the activation of only a portion of the reference signal resource sets and preventing the terminal equipment from being unable to perform fair measurement of the signal quality of multiple candidate cells.

[0020] Based on the first aspect, in one possible implementation, the method further includes: a first communication device receiving a third activation signaling, the third activation signaling being used to activate the reference signal resources of one of the P candidate cells.

[0021] In this implementation, the third activation signaling activates reference signal resources at the candidate cell level, which helps to improve the activation efficiency of reference signal resources and reduce activation signaling overhead.

[0022] Based on the first aspect, in one possible implementation, the reference signal resources included in the first reference signal resource group belong to N candidate cells, where N is an integer greater than or equal to 2, and the N candidate cells correspond one-to-one with the N third activation signaling.

[0023] N third-party activation signaling messages are carried in the same downlink signaling message, or N third-party activation signaling messages occupy the same time domain resources, or the time domain resources occupied by N third-party activation signaling messages are located in the same time period.

[0024] In this implementation, the reference signal resources of N candidate cells in the first reference signal resource group are limited to being activated simultaneously or within a certain time period. This avoids activating only the reference signal resources of some candidate cells and prevents the terminal device from being unable to perform fair measurement of the signal quality of multiple candidate cells.

[0025] Based on the first aspect, in one possible implementation, the downlink signaling is a medium access control protocol data unit (MAC PDU). This implementation provides a specific implementation of downlink signaling, which is beneficial for the implementation of the scheme.

[0026] Based on the first aspect, in one possible implementation, the measurement results include measurement results of at least one candidate cell. The measurement results of each candidate cell include measurement results of reference signals corresponding to M reference signal resources of that candidate cell. The M reference signal resources are some or all of the reference signal resources of the candidate cell in a first reference signal resource group. The at least one candidate cell belongs to P candidate cells, where M is a positive integer. This implementation illustrates the specific content included in the measurement results. The measurement results may include measurement results of some or all of the P candidate cells.

[0027] Based on the first aspect, in one possible implementation, the measurement results include L*M reference signal resource index fields and L*M signal quality indication fields, where L and M are both positive integers; the effective reference signal resources included in the first reference signal resource group belong to K candidate cells, where K candidate cells belong to P candidate cells, K is less than L, and K is a positive integer;

[0028] The first K*M reference signal resource index fields out of the L*M reference signal resource index fields are used to indicate the indexes of the M reference signal resources corresponding to the K candidate cells respectively;

[0029] The first K*M signal quality indication fields out of the L*M signal quality indication fields are used to indicate the signal quality of the M reference signal resources corresponding to the K candidate cells respectively;

[0030] The last (LK)*M reference signal resource index fields in the L*M reference signal resource index fields are reserved fields, or fields with all 0s, or fields with all 1s;

[0031] The last (LK)*M signal quality indicator fields out of the L*M signal quality indicator fields are reserved fields, or fields with all 0s, or fields with all 1s.

[0032] In this implementation, a reporting format for the measurement results is proposed, which facilitates the interpretation of the measurement results by the second communication device.

[0033] Based on the first aspect, in one possible implementation, the effective reference signal resources included in the first reference signal resource group belong to K candidate cells, and the K candidate cells belong to P candidate cells, where K is a positive integer;

[0034] When K is greater than or equal to L, the measurement results include L*M reference signal resource index fields and L*M signal quality indication fields. The L*M reference signal resource index fields are used to indicate the indexes of the M reference signal resources corresponding to the L candidate cells respectively. The L*M signal quality indication fields are used to indicate the signal quality of the M reference signal resources corresponding to the L candidate cells respectively. The L candidate cells belong to K candidate cells, and L and M are both positive integers.

[0035] When K is less than L, the measurement result includes K*M reference signal resource index fields and K*M signal quality indication fields. The K*M reference signal resource index fields are used to indicate the indexes of the M reference signal resources corresponding to the K candidate cells respectively, and the K*M signal quality indication fields are used to indicate the signal quality of the M reference signal resources corresponding to the K candidate cells respectively. L and M are both positive integers.

[0036] In this implementation, an alternative reporting format for the measurement results is proposed. The specific fields included in this format depend on the values ​​of L and K. This reporting format facilitates the interpretation of the measurement results by the second communication device.

[0037] A second aspect of this application provides a communication method applied to a second communication device; the second communication device is a network device, or a device applied to a network device. For example, it may include a chip, chip system, module, processing unit, control unit, or circuit in the network device, etc., and this application does not specifically limit the definition. It should be noted that, in this application, when referring to a network device, it can refer to the network device itself, or it can be replaced by a chip, functional module, or integrated circuit in the network device that performs the method provided in this application, and this application does not specifically limit the definition. The method includes: a second communication device transmitting a reference signal resource configuration, the reference signal resource configuration including a first reference signal resource group, the first reference signal resource group including some or all reference signal resources of P candidate cells, where P is a positive integer; the first reference signal resource group satisfies at least one of the following: when the first reference signal resource group includes the first reference signal resource of the first candidate cell, then the first reference signal resource group includes all reference signal resources in the reference signal resource set where the first reference signal resource is located, and the first candidate cell is one of the P candidate cells; when the first reference signal resource group includes the first reference signal resource of the first candidate cell, the first reference signal resource group includes all reference signal resources of the first candidate cell; or, when the first reference signal resource group includes the reference signal resources of multiple candidate cells, the first configuration parameters corresponding to the reference signal resources of the multiple candidate cells are the same, and the multiple candidate cells are some or all of the P candidate cells; the second communication device receiving a measurement result, the measurement result being the measurement result corresponding to the first reference signal resource group.

[0038] In the above technical solution, the second communication device transmits reference signal resource configuration, which includes a first reference signal resource group. The first reference signal resource group includes some or all of the reference signal resources of P candidate cells. This enables the second communication device to configure the reference signal resources of candidate cells for the first communication device. Furthermore, the configuration constraints of the reference signal resources in the first reference signal resource group are defined. This facilitates the terminal device in better measuring the signal quality of each candidate cell and providing corresponding measurement results to the network device, making it easier for the network device to instruct the terminal device to switch to a suitable candidate cell, thereby improving communication transmission performance. Furthermore, this solution facilitates the network device in managing the reference signal resources of candidate cells. For example, when the first reference signal resource group includes the first reference signal resource of the first candidate cell, the first reference signal resource group includes all reference signal resources in the reference signal resource set containing the first reference signal resource. Therefore, the first reference signal resource group includes the reference signal resources in the entire reference signal resource set, and the reference signal resources in the reference signal resource set often correspond to the same wide beam, while each reference signal resource in the reference signal resource set corresponds to a narrow beam; different reference signal resources can correspond to different narrow beams. Each reference signal resource in the reference signal resource set corresponds to a narrow beam located within the wide beam. The network device configures the terminal device to measure the reference signal resources in the entire reference signal resource set. This avoids missing measurements of some important beams. The terminal device can obtain the signal quality of each beam of the candidate cell and report it to the network device. This allows the network device to instruct the terminal device to switch to a suitable candidate cell based on the measurement results, thereby improving communication transmission performance. For example, when the first reference signal resource group includes the first reference signal resources of the first candidate cell, the first reference signal resource group includes all reference signal resources of the first candidate cell. Each reference signal resource corresponds to a narrow beam, and the network device configures the terminal device to measure all reference signal resources of the first candidate cell. This avoids missing measurements of some important beams of the first candidate cell. The terminal device can obtain the signal quality of each beam of the first candidate cell and report it to the network device. This allows the network device to instruct the terminal device to switch to a suitable candidate cell based on the measurement results, thereby improving communication transmission performance. For example, when the first reference signal resource group includes reference signal resources of multiple candidate cells, the reference signal resources of the multiple candidate cells correspond to the same first configuration parameters. This facilitates the management of reference signal resources for multiple candidate cells by network devices. Furthermore, the first configuration parameters corresponding to the reference signal resources of each candidate cell enable terminal devices to perform fair measurements on multiple candidate cells, avoiding situations where some candidate cells consume excessive measurement resources while others consume virtually none. This allows network devices to instruct terminal devices to switch to a suitable candidate cell, thereby improving communication transmission performance.

[0039] Based on the second aspect, in one possible implementation, the first configuration parameter includes at least one of the following: reference signal resource type, transmission period of the reference signal corresponding to the reference signal resource, transmission power, scrambling identifier for generating the sequence of the reference signal corresponding to the reference signal resource, subcarrier spacing used for transmitting the reference signal corresponding to the reference signal resource, or CP; wherein, the reference signal resource type includes periodic resources, semi-persistent resources, or aperiodic resources. This implementation provides the specific content included in the first configuration parameter. For example, having the same reference signal resource type, transmission period, and transmission power for multiple candidate cells helps ensure fair measurement of multiple candidate cells by the terminal device. Another example is having the same scrambling identifier for each of the multiple candidate cells, which helps ensure orthogonality of the reference signals corresponding to each of the multiple candidate cells, facilitating the terminal device to distinguish the reference signals corresponding to each of the multiple candidate cells. Yet another example is having the same subcarrier spacing for each of the multiple candidate cells, ensuring frequency domain granularity alignment of the reference signals corresponding to the multiple candidate cells. And yet another example is having the same CP for each of the multiple candidate cells, ensuring synchronization of the reference signals of the multiple candidate cells.

[0040] Based on the second aspect, in one possible implementation, the method further includes: a second communication device sending a reporting configuration, which is a reporting configuration associated with a reference signal resource configuration. The reporting configuration includes at least one of the following: the number L of candidate cells to be reported, or the reporting content included in the measurement results of each candidate cell to be reported, wherein the reporting content includes information on M reference signal resources of the candidate cells to be reported; the information on each reference signal resource includes the index of the reference signal resource and / or signal quality, where L and M are both positive integers. In this implementation, the second communication device sends the reporting configuration, thereby facilitating the first communication device to report the measurement results of the candidate cells based on the reporting configuration.

[0041] Based on the second aspect, in one possible implementation, the method further includes: a second communication device receiving configuration information, the configuration information indicating the reference signal resources of each candidate cell among P candidate cells. This facilitates the first communication device in obtaining the specific configuration of the reference signal resources in the first reference signal resource group, and facilitates the measurement and reporting of the reference signal resources of the candidate cells.

[0042] Based on the second aspect, in one possible implementation, the configuration information is used to indicate the reference signal resources of each candidate cell among the P candidate cells, including: the configuration information is used to indicate at least one set of reference signal resources corresponding to each candidate cell among the P candidate cells, and each set of reference signal resources includes one or more reference signal resources.

[0043] In this implementation, each candidate cell is configured with one or more corresponding sets of reference signal resources. This facilitates the management of reference signal resources and reduces the complexity of terminal equipment measuring these resources. For example, the network can be configured to allow terminal equipment to measure reference signal resources within the entire set. Since the terminal equipment can measure all reference signal resources in the set, it does not need to select specific reference signal resources from the set and then measure those selected resources. This further reduces the complexity of reference signal resource measurement for the terminal equipment.

[0044] Based on the second aspect, in one possible implementation, the reference signal resources in the first reference signal resource group are semi-persistent reference signal resources. The method further includes: a second communication device sending a first activation signaling message, which is used to activate the reference signal resources in the first reference signal resource group. In this implementation, the first activation signaling message activates the reference signal resources at the reference signal resource group level. This is beneficial for improving the activation efficiency of the reference signal resources and reducing the activation signaling overhead.

[0045] Based on the second aspect, in one possible implementation, the first activation signaling includes at least one of the following: an index of the first reference signal resource group, an index of the reference signal resource configuration to which the first reference signal resource group belongs, or an index of the reporting configuration associated with the reference signal resource configuration to which the first reference signal resource group belongs. This facilitates the first communication device to measure the reference signal resources in the first reference signal resource group based on the first activation signaling and report the corresponding measurement results to the second communication device. This enables the second communication device to obtain the measurement results.

[0046] Based on the second aspect, in one possible implementation, the method further includes: a second communication device sending a second activation signaling message, the second activation signaling message being used to activate a reference signal resource set of one of the P candidate cells. In this implementation, the second activation signaling message activates reference signal resources at the granularity of the reference signal resource set. This is beneficial for improving the activation efficiency of reference signal resources and reducing activation signaling overhead.

[0047] Based on the second aspect, in one possible implementation, the second activation signaling includes at least one of the following: an index of the reference signal resource set, or an index of the candidate cell.

[0048] Based on the second aspect, in one possible implementation, the reference signal resources included in the first reference signal resource group belong to Q sets of reference signal resources, where Q is an integer greater than or equal to 2. Each of the Q sets of reference signal resources corresponds one-to-one with a second activation signaling message. The Q second activation signaling messages are carried in the same downlink signaling message; or, the Q second activation signaling messages occupy the same time domain resources; or, the time domain resources occupied by the Q second activation signaling messages are located within the same time period. In this implementation, since the reference signal resources of the first reference signal resource group belong to Q sets of reference signal resources, the network can activate these Q sets of reference signal resources through the Q second activation signaling messages. Furthermore, it limits the activation of the Q sets of reference signal resources to either simultaneous activation or activation within a single time period, avoiding the activation of only a portion of the reference signal resource sets and preventing terminal devices from being unable to fairly measure the signal quality of multiple candidate cells.

[0049] Based on the second aspect, in one possible implementation, the method further includes: the second communication device sending a third activation signaling, which is used to activate the reference signal resources of one of the P candidate cells. In this implementation, the third activation signaling activates the reference signal resources at the candidate cell level, which is beneficial to improving the activation efficiency of the reference signal resources and reducing the activation signaling overhead.

[0050] Based on the second aspect, in one possible implementation, the reference signal resources of the first reference signal resource group belong to N candidate cells, where N is an integer greater than or equal to 2, and the N candidate cells correspond one-to-one with the N third activation signaling.

[0051] N third-party activation signaling messages are carried in the same downlink signaling message, or N third-party activation signaling messages occupy the same time domain resources, or the time domain resources occupied by N third-party activation signaling messages are located in the same time period.

[0052] In this implementation, the reference signal resources of N candidate cells in the first reference signal resource group are limited to being activated simultaneously or within a certain time period. This avoids activating only the reference signal resources of some candidate cells and prevents the terminal device from being unable to perform fair measurement of the signal quality of multiple candidate cells.

[0053] Based on the second aspect, in one possible implementation, the downlink signaling is a MAC PDU.

[0054] Based on the second aspect, in one possible implementation, the measurement results include measurement results of at least one candidate cell. The measurement results of each candidate cell include measurement results of reference signals corresponding to M reference signal resources of the candidate cell. The M reference signal resources are some or all of the reference signal resources of the candidate cell in a first reference signal resource group. The at least one candidate cell belongs to P candidate cells, where M is a positive integer. This implementation illustrates the specific content included in the measurement results. The measurement results may include measurement results of some or all of the P candidate cells.

[0055] Based on the second aspect, in one possible implementation, the measurement results include L*M reference signal resource index fields and L*M signal quality indication fields, where L and M are both positive integers; the effective reference signal resources included in the first reference signal resource group belong to K candidate cells, where K candidate cells belong to P candidate cells, K is less than L, and K is a positive integer;

[0056] The first K*M reference signal resource index fields out of the L*M reference signal resource index fields are used to indicate the indexes of the M reference signal resources corresponding to the K candidate cells respectively;

[0057] The first K*M signal quality indication fields out of the L*M signal quality indication fields are used to indicate the signal quality of the M reference signal resources corresponding to the K candidate cells respectively;

[0058] The last (LK)*M reference signal resource index fields in the L*M reference signal resource index fields are reserved fields, or fields with all 0s, or fields with all 1s;

[0059] The last (LK)*M signal quality indicator fields out of the L*M signal quality indicator fields are reserved fields, or fields with all 0s, or fields with all 1s.

[0060] In this implementation, a reporting format for the measurement results is proposed, which facilitates the interpretation of the measurement results by the second communication device.

[0061] Based on the second aspect, in one possible implementation, the method further includes: the second communication device ignoring the last (LK)*M reference signal resource index fields and the last (LK)*M signal quality indication fields among the L*M reference signal resource index fields. In this implementation, neither the last (LK)*M reference signal resource index fields nor the last (LK)*M signal quality indication fields indicate any meaning, therefore the second communication device can ignore these fields.

[0062] Based on the second aspect, in one possible implementation, the effective reference signal resources included in the first reference signal resource group belong to K candidate cells, and the K candidate cells belong to P candidate cells, where K is a positive integer;

[0063] When K is greater than or equal to L, the measurement results include L*M reference signal resource index fields and L*M signal quality indication fields. The L*M reference signal resource index fields are used to indicate the indexes of the M reference signal resources corresponding to the L candidate cells respectively. The L*M signal quality indication fields are used to indicate the signal quality of the M reference signal resources corresponding to the L candidate cells respectively. The L candidate cells belong to K candidate cells, and L and M are both positive integers.

[0064] When K is less than L, the measurement result includes K*M reference signal resource index fields and K*M signal quality indication fields. The K*M reference signal resource index fields are used to indicate the indexes of the M reference signal resources corresponding to the K candidate cells respectively, and the K*M signal quality indication fields are used to indicate the signal quality of the M reference signal resources corresponding to the K candidate cells respectively. L and M are both positive integers.

[0065] In this implementation, an alternative reporting format for the measurement results is proposed, which facilitates the interpretation of the measurement results by the second communication device.

[0066] A third aspect of this application provides a communication device, comprising:

[0142] The communication systems to which this application applies include terminal equipment and network equipment. Terminal equipment and network equipment are described below.

[0143] Terminal equipment, also known as user equipment (UE), mobile station (MS), mobile terminal (MT), fixed wireless access (FWA), customer premises equipment (CPE), etc., refers to devices that include wireless communication capabilities (providing voice / data connectivity to users). Examples include handheld devices with wireless connectivity, in-vehicle devices, and machine-type communication (MTC) terminals. Currently, terminal devices can include: mobile phones, tablets, laptops, PDAs, mobile internet devices (MIDs), wearable devices, virtual reality (VR) devices, augmented reality (AR) devices, wireless terminals in industrial control, wireless terminals in self-driving (e.g., drones, 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 can also be a device or module that is connected to the communication system shown above and has corresponding communication functions. The terminal device usually contains a communication module, circuit or chip that performs the corresponding communication function, and the terminal device is also configured with program instructions for performing the corresponding communication function.

[0144] It should be noted that the terminal device can be a device or apparatus with a chip, or a device or apparatus with integrated circuitry, or a chip, chip system, module, or control unit in the device or apparatus shown above; this application does not impose any specific limitation. It should also be noted that in this application, when referring to a terminal device, it can refer to the terminal device itself, or it can be replaced with a chip, functional module, or integrated circuit in the terminal device that performs the method provided in this application; this application does not impose any specific limitation.

[0145] A network device is a device deployed in a radio access network to provide wireless communication functions for terminal devices. Network devices may also be referred to as radio access network (RAN) entities, access nodes, network nodes, access network equipment, or communication devices, etc.

[0146] Specifically, the network equipment can be access network equipment for cellular systems related to the 3rd Generation Partnership Project (3GPP). For example, fourth-generation (4G) mobile communication systems, 5G mobile communication systems, or future mobile communication systems. The network equipment can also be access network equipment in open RAN (O-RAN or ORAN) or cloud radio access network (CRAN). Alternatively, the network equipment can also be access network equipment in a communication system resulting from the integration of two or more of the above communication systems.

[0147] Network equipment includes, but is not limited to: 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), baseband unit (BBU), access point (AP) in wireless fidelity (WIFI) systems, macro base station, micro base station, wireless relay node, donor node, radio controller in CRAN scenarios, wireless backhaul node, transmission point (TP), or transmission and reception point (or transmit / receive point, TRP). Network equipment can also be access network equipment in 5G mobile communication systems. For example, a next-generation NodeB (gNB), TRP, TP in a new radio (NR) system, or one or a group of antenna panels (including multiple antenna panels) in a base station in a 5G mobile communication system. Alternatively, network equipment can also be network nodes that constitute a gNB or transmission point. For example, a centralized unit (CU), a distributed unit (DU), a CU-control plane (CP), a CU-user plane (UP), or a radio unit (RU), etc. CU and DU can be set up separately or included in the same network element. For example, a BBU. RU can be included in radio equipment or radio units. For example, in a remote radio unit (RRU), an active antenna unit (AAU), or a remote radiohead (RRH). Alternatively, network equipment can also be a server, wearable device, vehicle, or in-vehicle equipment, etc. For example, in V2X technology, network equipment can be a roadside unit (RSU).

[0148] It should be noted that CU (or CU-CP and CU-UP), DU, or RU may have different names in different systems, but those skilled in the art will understand their meaning. For example, in an ORAN system, CU can also be called an open centralized unit (O-CU) or an open CU, DU can also be called an open distributed unit (O-DU), centralized unit control plane (CU-CP) can also be called an open centralized unit control plane (O-CU-CP) or an open CU-CP, centralized unit user plane (CU-UP) can also be called an open centralized unit user plane (O-CU-UP) or an open CU-UP, and RU can also be called an open radio unit (O-RU). This application does not impose any specific limitations. Any of the units CU, CU-CP, CU-UP, DU, and RU in this application can be implemented through software modules, hardware modules, or a combination of software and hardware modules.

[0149] Figure 1 This is a schematic diagram of an ORAN system according to an embodiment of this application. The ORAN system includes a core network, access network equipment, and UEs. Optionally, the ORAN system may further include... Figure 1 Other components besides those shown are not specifically limited in this application.

[0150] Access network devices can communicate with the core network (CN) via a backhaul link. Access network devices can also communicate with the UE via an air interface. Specifically, the BBU in the access network device communicates with the core network via a backhaul link. The RU in the access network device communicates with at least one UE via an air interface. The BBU communicates with at least one RU via a fronthaul link; the BBU and RU may or may not be co-located.

[0151] A BBU consists of at least one CU and at least one DU, and the CU and DU can communicate with each other via at least one midhaul link.

[0152] One possible implementation is, such as Figure 2As shown, the CU is a logical node that carries the radio resource control (RRC), service data adaptation protocol (SDAP) layer, packet data convergence protocol (PDCP) layer, and other control functions of access network equipment. The CU can connect to network nodes such as the core network through interfaces, such as the E2 interface. Optionally, the CU can have some core network functions. The CU (e.g., the PDCP layer and / or higher) connects to the DU (e.g., the radio link control (RLC) layer and lower layers of the DU) through interfaces, such as the F1 interface. Optionally, the F1 interface can provide control plane (C-Plane) and user plane (U-Plane) functions (e.g., interface management, system information management, UE context management, RRC message transmission, etc.). F1AP is the application protocol of the F1 interface, defining the signaling procedures of F1 in some examples. The F1 interface supports control plane F1-C and user plane F1-U.

[0153] Optional, such as Figure 2As shown, the CU can be divided into CU-CP and CU-UP. CU-CP is a logical node carrying the control plane (PDCP-C) layer, which carries the RRC layer and the Packet Data Convergence Protocol layer, and is used to implement the CU's control plane functions. CU-CP can interact with network elements in the core network used to implement control plane functions. These network elements in the core network can be access and mobility function (AMF) network elements, such as the access and mobility management function (AMF) in a 5G system. The AMF network element is responsible for mobility management in the mobile network, such as terminal device location updates, terminal device registration with the network, and terminal device handover. CU-UP is a logical node carrying the user plane (PDCP-U) layer, which carries the SDAP layer and the Packet Data Convergence Protocol layer, and is used to implement the CU's user plane functions. CU-UP can interact with network elements in the core network used to implement user plane functions. These network elements in the core network, such as the user plane function (UPF) in a 5G system, are responsible for data forwarding and receiving in terminal devices. The above CU and DU configurations are merely examples. In practical applications, the functions of the CU and DU can be configured as needed. For instance, the CU or DU can be configured to have more protocol layer functions, or to have only some protocol layer processing functions. For example, some RLC layer functions and protocol layer functions above the RLC layer can be placed in the CU, while the remaining RLC layer functions and protocol layer functions below the RLC layer can be placed in the DU. Furthermore, the functions of the CU or DU can be divided according to service type or other system requirements. For example, based on latency, functions that require low latency can be placed in the DU, while functions that do not require low latency can be placed in the CU.

[0154] One possible implementation is, such as Figure 2 As shown, a DU is a logical node that carries the RLC layer, medium access control (MAC) layer, higher physical layer (Higher PHY) layer, and other functions. In some examples, a DU can control at least one RU. The DU connects to the RU through interfaces, which can be fronthaul interfaces. In some examples, the Higher PHY layer includes the PHY layer processing, such as forward error correction (FEC) encoding and decoding, scrambling, modulation, and demodulation.

[0155] One possible implementation is, such as Figure 2 As shown, the RU is a logical node that carries both lower physical layer (PHY) and radio frequency (RF) processing. In some examples, the RU can be a 3GPP transmission reception point (TRP), a remote radio head (RRH), or other similar entities. In some examples, the Low-PHY includes PHY processing functions such as Fast Fourier Transform (FFT), Inverse Fast Fourier Transform (IFFT), digital beamforming, and filtering. The RU communicates with one or more UEs via a radio link.

[0156] The DU and RU can be co-located or not. The DU and RU exchange control plane and user plane information via a fronthaul link through the Lower-Layer Split CUS-Plane (LLS-CUS) interface. LLS-CUS may include a Lower-Layer Split control (LLS-C) interface and a Lower-Layer Splituser (LLS-U) interface, providing the control plane (C-Plane) and user plane (U-Plane) respectively. In some examples, the control plane (C-Plane) refers to real-time control between the DU and RU. The DU and RU exchange management information via a Lower-Layer Split management (LLS-M) interface on the fronthaul link; the management plane (M-Plane) refers to non-real-time management operations between the DU and RU.

[0157] DU and RU can cooperate to implement the functions of the PHY layer. A DU can be connected to one or more RUs. The functions of DU and RU can be configured in various ways depending on the design. For example, a DU can be configured to implement baseband functions, and an RU can be configured to implement mid-RF functions. Another example is that a DU can be configured to implement higher-level functions in the PHY layer, and an RU can be configured to implement lower-level functions in the PHY layer, or to implement both lower-level and RF functions. Higher-level functions in the physical layer can include a portion of the physical layer's functions that are closer to the MAC layer, while lower-level functions in the physical layer can include another portion of the physical layer's functions that are closer to the mid-RF side.

[0158] In different systems, CU (or CU-CP and CU-UP), DU, or RU may have different names, but those skilled in the art will understand their meaning. For example, in an ORAN system, CU can also be called O-CU (open CU), DU can also be called O-DU, CU-CP can also be called O-CU-CP, CU-UP can also be called O-CU-UP, and RU can also be called O-RU. For ease of description, this application uses CU, CU-CP, CU-UP, DU, and RU as examples.

[0159] It should be noted that network devices can be devices or apparatuses with chips, or devices or apparatuses with integrated circuits, or chips, chip systems, modules, or control units in the devices or apparatuses shown above; this application does not impose any specific limitations. It should also be noted that in this application, when referring to network devices, it can refer to the network device itself, or it can be replaced with the chips, functional modules, or integrated circuits in the network device that implement the methods provided in this application; this application does not impose any specific limitations.

[0160] Please see Figure 3 This is a schematic diagram of the architecture of the communication system 1000 used in an embodiment of this application. Figure 3 As shown, the communication system includes RAN 100. Optionally, the communication system 1000 also includes a core network 200 and an Internet 300. RAN 100 includes at least one RAN node (e.g., Figure 3 110a and 110b, collectively referred to as 110, may also include at least one terminal device (such as...). Figure 3 RAN 100, denoted as RAN 120a-120j, is collectively referred to as RAN 120. RAN 100 may also include other RAN nodes, such as wireless relay equipment and / or wireless backhaul equipment.

The core network equipment in core network 200 and RAN node 110 in RAN 100 can be independent physical devices, or they can be the same physical device integrating the logical functions of core network equipment and RAN nodes. Terminal devices and RAN nodes can be interconnected via wired or wireless means.

[0161] The technical terms used in this application are described below.

[0162] Beam: A beam is a communication resource. A beam can be wide, narrow, or other types of beam. Beamforming techniques can be beamforming technology or other methods. Beamforming technologies include digital beamforming, analog beamforming, and hybrid digital / analog beamforming. Different beams can be considered different resources.

[0163] In the NR protocol, a beam can be referred to as a spatial domain filter, spatial filter, spatial domain parameter, spatial parameter, spatial domain setting, spatial setting, quasi-colocation (QCL) information, QCL assumption, or QCL indication, etc. The beam can be indicated by the transmission configuration indicator state (TCI-state) parameter or by the spatial relation parameter. Therefore, in this application, the beam can be replaced by spatial domain filter, spatial filter, spatial parameter, spatial parameter, spatial setting, spatial setting, QCL information, QCL assumption, QCL indication, TCI-state (where TCI-state includes uplink TCI-state and downlink TCI-state), or spatial relation, etc. The above terms are also equivalent to each other. The beam can also be replaced with other beam-related terms, which are not limited herein.

[0164] The beam used to transmit signals can be called a transmission beam (Tx beam), a spatial domain transmission filter, a spatial transmission filter, a spatial domain transmission parameter, a spatial transmission parameter, a spatial domain transmission setting, or a spatial transmission setting. The transmission beam can also be called a downlink beam.

[0165] The beam used to receive signals can be called a reception beam (Rx beam), a spatial domain reception filter, a spatial reception filter, a spatial domain reception parameter, a spatial reception parameter, a spatial domain reception setting, or a spatial reception setting. The reception beam can also be called the uplink beam. The uplink transmission beam can be indicated by any of the following: spatial relation, uplink TCI-state, or sounding reference signal (SRS) resource (indicating the transmission beam using that SRS).

[0166] The transmit beam refers to the distribution of signal strength in different directions in space after a signal is transmitted through an antenna. The receive beam refers to the distribution of signal strength in different directions in space of the wireless signal received from the antenna.

[0167] Beams are generally associated with resources. For example, during beam measurement, network devices measure different beams using different resources. The terminal device provides feedback on the measured resource quality, allowing the network device to determine the quality of the corresponding beam. During data transmission, beam information is also indicated through its corresponding resources. For instance, network devices use the TCI field in downlink control information (DCI) to indicate beam information to the terminal device. Therefore, beams and resources can be considered equivalent.

[0168] Resources: In communication protocols, reference signals are configured as resources. Network devices allocate various reference signals to terminal devices as resources. Resource configuration information can include parameters related to the reference signal, such as its time-frequency resource location, number of ports, and time-domain type. The time-domain type can also be understood as the type of resource. For example, the time-domain type can be periodic, semi-persistent, or aperiodic. Semi-persistent can also be called semi-static.

[0169] Resources can be either uplink or downlink signal resources. Uplink signals include, but are not limited to, sounding reference signals (SRS) and demodulation reference signals (DMRS). Downlink signals include, but are not limited to, channel state information reference signals (CSI-RS), cell specific reference signals (CS-RS), user equipment specific reference signals (US-RS), demodulation reference signals (DMRS), and synchronization signal / physical broadcast channel blocks (SS / PBCH blocks). The SS / PBCH block can be abbreviated as synchronization signal block (SSB). CSI-RS also includes non-zero power CSI-RS (NZP CSI-RS) and zero power CSI-RS (ZP CSI-RS).

[0170] Resources can also be called measurement resources or reference signal resources. In other words, resources, measurement resources, and reference signal resources are interchangeable. The following text will use reference signal resources as an example.

[0171] Serving Cell: A serving cell is a cell configured by network equipment for transmission by terminal equipment. A serving cell can be the primary cell (Pcell), secondary cell (Scell), or primary secondary cell (PScell) of the terminal equipment. Cells using the primary component carrier (PCC) can be called Pcells, and cells using the secondary component carrier (SCC) can be called Scells.

[0172] Candidate cells: Candidate cells are cells other than the serving cell. For example, a candidate cell can be a neighboring cell of the terminal device's serving cell. The physical cell identifier (PCI) of a candidate cell is different from that of the terminal device's serving cell.

[0173] Reference signal: This can be an uplink reference signal or a downlink reference signal. Uplink reference signals include, but are not limited to, SRS and DMRS. Downlink reference signals include, but are not limited to, CSI-RS, CS-RS, US-RS, DMRS, and SSB. CSI-RS also includes: non-zero power CSI-RS, and / or, zero power CSI-RS.

[0174] As a terminal device moves, it moves from the signal coverage area of ​​one cell to the signal coverage area of ​​another. The network device can instruct the terminal device to hand over to another cell. Specifically, before handing over, the terminal device needs to perform cell measurements. The following example illustrates how the terminal device measures the SSB (Special Service Base) of a candidate cell to perform these measurements.

[0175] The terminal device can measure the synchronization signal block (SSB) of the serving cell and the SSBs of one or more candidate cells. Specifically, the network device configures a resource set for the terminal device, which includes the SSB resources of the serving cell and the SSB resources of W candidate cells. W is a positive integer. The terminal device measures the SSB resources in this resource set to obtain the signal quality of all SSB resources in W+1 cells. Then, the terminal device reports the measurement results. The measurement results include the measurement results of each of the P cells. The measurement results for each cell include the indices of B SSB resources of that cell and the reference signal receiving power (RSRP) of those B SSB resources. P is less than or equal to W+1, and P and B are both positive integers. As shown in Table 1, the measurement results include the indices of P*B SSB resources and the RSRP of P*B SSB resources.

[0176] Table 1

[0177]

[0178]

[0179] Optionally, the P cells are the P cells with the best signal quality among W+1 cells. After receiving the measurement results reported by the terminal device, the network device determines whether to update the terminal device's serving cell based on the measurement results. When the network device finds that a candidate cell among the P cells has a stronger signal quality than the terminal device's serving cell, the network device can send a cell handover signaling message to the terminal device. This cell handover signaling message instructs the terminal device to hand over to the candidate cell. The terminal device hands over to the candidate cell according to the cell handover signaling message. The terminal device then transmits data with the network device in the candidate cell. Figure 4 As shown, the terminal device moves from the serving cell to candidate cell #2. The terminal device measures the SSB resources corresponding to the serving cell, candidate cell 1, and candidate cell 2 respectively, obtains the measurement results, and reports them to the network device. Based on the measurement results reported by the terminal device, the network device finds that the signal quality of candidate cell 2 is better than that of the serving cell. The network device can then instruct the terminal device to hand over from the serving cell to candidate cell 2.

[0180] It should be noted that the network equipment belonging to the serving cell (i.e., the network equipment managing the serving cell) and the network equipment belonging to the candidate cell can be the same network equipment or different network equipment; this application does not impose any specific restrictions. The following text mainly uses the example of the network equipment belonging to the serving cell and the network equipment belonging to the candidate cell being the same network equipment to introduce the technical solution of this application.

[0181] However, how network devices configure reference signal resources for candidate cells for terminal devices to facilitate better measurement of these resources is a problem worth considering. This application provides a corresponding technical solution, which can be found in the following description of the embodiments.

[0182] The communication system to which the technical solution provided in this application applies includes a first communication device and a second communication device. The first communication device is a terminal device, or a device applied to a terminal device. For example, it may be a chip, chip system, module, processing unit, control unit, or circuit, etc., and this application does not limit its specific application. The second communication device is a network device, or a device applied to a network device. For example, it may be a chip, chip system, module, processing unit, control unit, or circuit, etc., and this application does not limit its specific application.

[0183] In this application, the signal quality may optionally include at least one of the following: reference signal receiving power (RSRP), signal to interference plus noise ratio (SINR), or reference signal receiving quality (RSRQ), and this application does not limit the specifics.

[0184] The technical solution of this application is described below with reference to specific embodiments.

[0185] Figure 5 This is a schematic diagram of one embodiment of the communication method described in this application. Please refer to... Figure 5 The method includes the following steps.

[0186] 501. The second communication device sends a reference signal resource configuration to the first communication device. Correspondingly, the first communication device receives the reference signal resource configuration from the second communication device.

[0187] The reference signal resource configuration is used to indicate the first reference signal resource group. The first reference signal resource group includes some or all of the reference signal resources of P candidate cells of the first communication device, where P is a positive integer.

[0188] Optionally, the reference signal resource may be a channel status information reference signal (CSI-RS) resource or an SSB resource; this application does not specify which one.

[0189] In one possible implementation, the reference signal resource configuration includes a first reference signal resource group. This first reference signal resource group includes an index of each reference signal resource in some or all of the reference signal resources of the P candidate cells, and an identifier of the candidate cell corresponding to each reference signal resource.

[0190] For example, the first reference signal resource group includes a reference signal resource list and a candidate cell identifier list. The reference signal resource list includes indices of some or all of the reference signal resources of the P candidate cells. The candidate cell identifier list includes the candidate cell identifier corresponding to each reference signal resource in the reference signal resource list. The indices in the reference signal resource list correspond one-to-one with the cell identifiers in the candidate cell identifier list. For example, the reference signal resource list can be represented as Table 2 below.

[0191] Table 2

[0192] Reference Signal Resource Index Reference Signal Resource Index 1 Reference Signal Resource Index 2 Reference Signal Resource Index 3

[0193] The list of candidate cell identifiers can be represented as shown in Table 3 below.

[0194] Table 3

[0195] Community signage Community sign 1 Community sign 2 Community sign 3

[0196] It can be seen that the reference signal resource identified by reference signal resource index 1 is the reference signal resource of the candidate cell identified by cell identifier 1. The reference signal resource identified by reference signal resource index 2 is the reference signal resource of the candidate cell identified by cell identifier 2. The reference signal resource identified by reference signal resource index 3 is the reference signal resource of the candidate cell identified by cell identifier 3.

[0197] For example, the first reference signal resource group includes a list containing the index of each reference signal resource in some or all of the reference signal resources of the P candidate cells, and the identifier of the corresponding candidate cell. For example, this list is represented as Table 4 below.

[0198] Table 4

[0199] Reference Signal Resource Index Community signage Reference Signal Resource Index 1 Community sign 1 Reference Signal Resource Index 2 Community sign 2 Reference Signal Resource Index 3 Community sign 3

[0200] It can be seen that the reference signal resource identified by reference signal resource index 1 is the reference signal resource of the candidate cell identified by cell identifier 1. The reference signal resource identified by reference signal resource index 2 is the reference signal resource of the candidate cell identified by cell identifier 2. The reference signal resource identified by reference signal resource index 3 is the reference signal resource of the candidate cell identified by cell identifier 3.

[0201] In this implementation, the first communication device determines some or all of the reference signal resources of the P candidate cells using the indexes of the reference signal resources in the first reference signal resource group. Optionally, the second communication device configures the reference signal resources of each candidate cell for the first communication device. This facilitates the first communication device in determining some or all of the reference signal resources of the P candidate cells based on the indexes of the reference signal resources in the first reference signal resource group.

[0202] Optional, Figure 5 The illustrated embodiment also includes step 501a.

[0203] 501a. The second communication device sends configuration information to the first communication device. Correspondingly, the first communication device receives the configuration information from the second communication device.

[0204] The configuration information is used to indicate the reference signal resources of each of the P candidate cells. For example, the configuration information includes the configuration information of the reference signal resources of each of the P candidate cells. For example, the configuration information includes at least one of the following: the reference signal resource type, time-frequency resources, transmission period, transmission power, number of ports, or the sequence used to generate the reference signal for the reference signal of each candidate cell among the multiple candidate cells.

[0205] Optionally, the configuration information is used to indicate at least one set of reference signal resources corresponding to each of the P candidate cells, and each set of reference signal resources includes one or more reference signal resources.

[0206] In this implementation, each candidate cell corresponds to one or more sets of reference signal resources. Each set of reference signal resources includes the reference signal resources of one candidate cell. Different candidate cells correspond to different sets of reference signal resources.

[0207] In this implementation, optionally, the first reference signal resource group includes a portion or all of the reference signal resource set corresponding to each of the P candidate cells. For example, if the first reference signal resource group includes all the reference signal resources of the P candidate cells, then the first reference signal resource group includes all the reference signal resource set corresponding to each of the P candidate cells.

[0208] Optionally, the configuration information includes the identifier of at least one set of reference signal resources corresponding to each candidate cell.

[0209] It should be noted that there is no fixed execution order between steps 501a and 501, and this application does not impose any restrictions on this. For example, step 501a may be executed first, followed by step 501; or step 501 may be executed first, followed by step 501a; or, depending on the circumstances, steps 501a and 501 may be executed simultaneously, and this application does not impose any restrictions on this. In other words, the reference signal resource configuration and configuration information can be sent simultaneously or separately, and this application does not impose any restrictions on this.

[0210] Optionally, the reference signal resource configuration and configuration information can be carried in the same signaling or different signaling, and this application does not impose any specific restrictions. For example, the reference signal resource configuration and configuration information can be carried in the configuration signaling of the serving cell.

[0211] In another possible implementation, the reference signal resource configuration includes an identifier for a first reference signal resource group. The first reference signal resource group includes configuration information for some or all of the reference signal resources of the P candidate cells. For example, the first reference signal resource group includes the reference signal resource type, time-frequency resources, transmission period, transmission power, number of ports, or the sequence used to generate the reference signal for each of the P candidate cells. The first communication device determines the first reference signal resource group based on its identifier. Then, the first communication device determines some or all of the reference signal resources of the P candidate cells based on the first reference signal resource group.

[0212] Optionally, the first reference signal resource group satisfies at least one of the following:

[0213] 1. When the first reference signal resource group includes the first reference signal resource of the first candidate cell, the first reference signal resource group includes all reference signal resources in the reference signal resource set where the first reference signal resource is located, and the first candidate cell is one of the P candidate cells.

[0214] Specifically, each candidate cell corresponds to at least one set of reference signal resources. Each set of reference signal resources includes the reference signal resources of one candidate cell. Different candidate cells correspond to different sets of reference signal resources. If the first set of reference signal resources includes the first reference signal resources of the first candidate cell, then the first set of reference signal resources includes all reference signal resources in the set of reference signal resources containing the first reference signal. Therefore, the first set of reference signal resources includes all reference signal resources in the entire set of reference signal resources. Reference signal resources in a set of reference signal resources often correspond to the same wide beam, and each reference signal resource in the set corresponds to a narrow beam. Different reference signal resources can correspond to different narrow beams. The narrow beam corresponding to each reference signal resource in the set of reference signal resources is located within the wide beam. Network devices configure terminal devices to measure the reference signal resources in the entire set of reference signal resources, avoiding the omission of measurements for some important beams. Terminal devices can obtain the signal quality of each beam in a candidate cell and report it to the network device. This allows the network device to instruct the terminal device to switch to a suitable candidate cell based on the measurement results, thereby improving communication transmission performance.

[0215] 2. When the first reference signal resource group includes the first reference signal resources of the first candidate cell, the first reference signal resource group includes all the reference signal resources of the first candidate cell.

[0216] In this implementation, if the first reference signal resource group includes the first reference signal resources of the first candidate cell, then the first reference signal resource group includes all reference signal resources of the first candidate cell. The second communication device configures the first communication device to measure all reference signal resources of the first candidate cell. Each reference signal resource corresponds to a narrow beam, and the network device configures the terminal device to measure all reference signal resources of the first candidate cell. This avoids missing measurements of some important beams in the first candidate cell. The terminal device can obtain the signal quality of each beam of the first candidate cell and report it to the network device. Based on the measurement results, the network device instructs the terminal device to switch to a suitable candidate cell, thereby improving communication transmission performance.

[0217] 3. When the first reference signal resource group includes reference signal resources of multiple candidate cells, the reference signal resources of multiple candidate cells correspond to the same first configuration parameters, and the multiple candidate cells are some or all of the candidate cells among P candidate cells.

[0218] The third point above facilitates the management of reference signal resources for multiple candidate cells by network devices. Furthermore, the first configuration parameters corresponding to the reference signal resources of each candidate cell enable terminal devices to perform fair measurements on multiple candidate cells, avoiding situations where some candidate cells consume excessive measurement resources while others consume virtually none. This allows network devices to instruct terminal devices to switch to suitable candidate cells, thereby improving communication transmission performance.

[0219] Optionally, the first configuration parameter includes at least one of the following:

[0220] 1. Reference signal resource type. In one possible implementation, the reference signal resource type includes periodic resources, semi-persistent resources, or aperiodic resources. In another possible implementation, the reference signal resource type includes periodic resources, semi-persistent resources, aperiodic resources, or resources triggered by the terminal device.

[0221] 2. The transmission period of the reference signal corresponding to the reference signal resource. Here, the reference signal corresponding to the reference signal resource refers to the reference signal carried on the reference signal resource. This reference signal resource is either a periodic reference signal resource or a semi-persistent reference signal resource.

[0222] 3. The transmission power of the reference signal corresponding to the reference signal resource.

[0223] The third item above can also be described as: the difference between the transmission power of the reference signal corresponding to the reference signal resource and the transmission power of the SSB. For example, if the reference signal resource is a CSI-RS resource, the difference between the transmission power of the CSI-RS carried on the CSI-RS resource and the transmission power of the SSB.

[0224] Having multiple candidate cells with the same reference signal resource type, transmission period, and transmission power helps ensure fair measurement of multiple candidate cells by the terminal equipment.

[0225] 4. Scrambling identifiers used to generate the sequence of reference signals corresponding to the reference signal resources.

[0226] The scrambling identifier is a generation parameter of the sequence used to generate the reference signal corresponding to the reference signal resource. Having the same scrambling identifier for multiple candidate cells helps ensure that the same sequence is used to generate the reference signal for all candidate cells, thus guaranteeing the orthogonality between the reference signals of multiple candidate cells.

[0227] 5. The subcarrier spacing used for the reference signal corresponding to the transmitted reference signal resource.

[0228] Having multiple candidate cells with the same subcarrier spacing helps ensure the frequency domain granularity alignment of the reference signals of multiple candidate cells.

[0229] 6. The reference signal using the transmitted reference signal resource. Specifically, using the same CP for the reference signals of multiple candidate cells helps ensure the orthogonality between the reference signals of multiple candidate cells.

[0230] Optional, Figure 5 The illustrated embodiment also includes step 501b. Step 501b may be performed before step 502.

[0231] 501b. The second communication device sends a configuration report to the first communication device. Correspondingly, the first communication device receives the configuration report from the second communication device.

[0232] Among them, the reporting configuration is the reporting configuration associated with the reference signal resource configuration.

[0233] Optionally, the reporting configuration indicates at least one of the following: the number L of candidate cells to be reported, or the reporting content included in the measurement results of each candidate cell to be reported, wherein the reporting content includes information on M reference signal resources of the candidate cells to be reported. The information on each reference signal resource includes the index of the reference signal resource and / or signal quality, where L and M are both positive integers. For example, the information on each reference signal resource includes the index of the reference signal resource and the RSRP of the reference signal resource. The candidate cells to be reported refer to the candidate cells reported by the first communication device in the measurement results.

[0234] In this implementation, the first communication device receives the reported configuration, which facilitates the first communication device to report the measurement results of the candidate cells based on the reported configuration.

[0235] It should be noted that there is no fixed execution order between steps 501b and 501, and this application does not impose any restrictions on this. For example, step 501b may be executed first, followed by step 501; or step 501 may be executed first, followed by step 501b; or, depending on the circumstances, steps 501b and 501 may be executed simultaneously. In other words, the reference signal resource configuration and the reporting configuration can be sent simultaneously or separately, and this application does not impose any restrictions on this.

[0236] Optionally, the reference signal resource configuration and the reported configuration can carry the same signaling or different signaling; this application does not specify the specifics. For example, the reference signal resource configuration may be carried in the configuration signaling of the serving cell, while the reported configuration may be carried in the configuration signaling of cell handover.

[0237] It should be noted that, if Figure 5 The illustrated embodiment includes step 501a. There is no fixed execution order between steps 501a, 501, and 501b, and this application does not impose any specific restrictions. That is, the reference signal resource configuration, configuration information, and reported configuration can be sent simultaneously or separately, and this application does not impose any specific restrictions.

[0238] Optionally, reference signal resources, configuration information, and reported configuration can be carried in the same signaling or different signaling. For example, reference signal resource configuration and configuration information can be carried in the configuration signaling of the serving cell, while reported configuration can be carried in the configuration signaling of cell handover.

[0239] Optional, Figure 5 The illustrated embodiment also includes step 500. Step 500 may be performed before step 501.

[0240] 500. The first communication device sends capability information to the second communication device. Correspondingly, the second communication device receives the capability information from the first communication device.

[0241] The capability information includes at least one of the following: whether the first communication device supports measuring the reference signal resources of the candidate cell, and the number of reference signal resources that the first communication device supports measuring.

[0242] In one possible implementation, the reference signal resources in the first reference signal resource group are periodic reference signal resources. After step 501 above, the first communication device measures the reference signals corresponding to the reference signal resources in the first reference signal resource group to obtain the measurement results of each candidate cell in the P candidate cells. For example, the measurement results of each candidate cell may include the index and signal quality of each reference signal resource of that candidate cell in the first reference signal resource group. For example, the P candidate cells include candidate cell #1 and candidate cell #2. The first reference signal resource group includes reference signal resource 1 and reference signal resource 2 of candidate cell #1, and reference signal resource 3 and reference signal resource 4 of candidate cell #2. Then the measurement results of candidate cell #1 include the index of reference signal resource 1, the index of reference signal resource 2, the signal quality of reference signal resource 1, and the signal quality of reference signal resource 2. The measurement results of candidate cell #2 include the index of reference signal resource 3, the index of reference signal resource 4, the signal quality of reference signal resource 3, and the signal quality of reference signal resource 4.

[0243] In another possible implementation, the reference signal resources in the first reference signal resource group are semi-persistent reference signal resources. Optionally, the second communication device activates the reference signal resources in the first reference signal resource group for the first communication device. Several possible activation methods are described below.

[0244] The following section describes implementation method one in conjunction with step 502a. Optional, Figure 5 The illustrated embodiment also includes step 502a. Step 502a may be performed after step 501 and before step 502.

[0245] 502a. The second communication device sends a first activation signaling message to the first communication device. Correspondingly, the first communication device receives the first activation signaling message from the second communication device.

[0246] The first activation signaling is used to activate the reference signal resources in the first reference signal resource group.

[0247] In this implementation, the first activation signaling activates reference signal resources at the reference signal resource group level. This improves the activation efficiency of reference signal resources and reduces activation signaling overhead.

[0248] Optionally, the first activation signaling includes at least one of the following: an index of the first reference signal resource group, an index of the reference signal resource configuration to which the first reference signal resource group belongs, or an index of the reporting configuration associated with the reference signal resource configuration to which the first reference signal resource group belongs.

[0249] Optionally, the first activation signaling is a medium access control element (MAC CE).

[0250] The second implementation method will be described below with reference to step 502b. Optional, Figure 5 The illustrated embodiment also includes step 502b. Step 502b may be performed before step 502.

[0251] 502b. The second communication device sends a second activation signaling to the first communication device. Correspondingly, the first communication device receives the second activation signaling from the second communication device.

[0252] The second activation signaling is used to activate a set of reference signal resources for a candidate cell. For example, the second activation signaling is used to activate a set of reference signal resources for one of P candidate cells. In this implementation, the second activation signaling activates reference signal resources at the granularity of the set of reference signal resources. This helps improve the activation efficiency of reference signal resources and reduce activation signaling overhead.

[0253] Optionally, if the first reference resource signal group includes some or all of the reference signal resources in the reference signal resource set, then it means that some or all of the reference signal resources in the first reference signal resource group are activated.

[0254] Optionally, the second activation signaling includes at least one of the following: an index of the reference signal resource set, or an index of the candidate cell to which the reference signal resource set belongs.

[0255] Optionally, the second activation signaling is MAC CE.

[0256] Optionally, the reference signal resources included in the first reference signal resource group belong to Q sets of reference signal resources, where Q is an integer greater than or equal to 2. Each of the Q sets of reference signal resources corresponds one-to-one with a second activation signaling message. That is, the second communication device can activate the Q sets of reference signal resources using the Q second activation signaling messages, thereby activating all reference signal resources in the first reference signal resource group.

[0257] Optionally, the Q sets of reference signal resources can be the sets of reference signal resources corresponding to one or more candidate cells.

[0258] Optionally, the following describes some possible bearer methods for the Q second activation signaling.

[0259] 1. Q second activation signaling messages are carried in the same downlink signaling. For example, the downlink signaling is a MAC PDU. The Q second activation signaling messages can be sent to the first communication device simultaneously, ensuring that the reference signal resources in the Q sets of reference signal resources are activated simultaneously.

[0260] 2. The Q second activation signaling messages occupy the same time-domain resources. That is, the second communication device sends these Q second activation signaling messages simultaneously. For example, the Q second activation signaling messages are carried in a single physical uplink shared channel (PUSCH). These Q second activation signaling messages can be sent simultaneously to the first communication device, ensuring that the resources in the Q reference signal resource sets are activated simultaneously.

[0261] 3. The time-domain resources occupied by the Q second activation signaling messages are located within the same time period. This time period includes one or more time units. For example, a time unit can be a time-domain symbol, time slot, subframe, frame, millisecond, or second, etc., and this application does not limit the specifics. For example, the Q second activation signaling messages include second activation signaling 1 and second activation signaling 2. Second activation signaling 1 is carried on PUSCH1, and second activation signaling 2 is carried on PUSCH2. PUSCH1 occupies time slot 1, while PUSCH2 occupies time slot 2. Time slot 1 is one time unit within this time period, and time slot 2 is another time unit within this time period.

[0262] The following section, using step 502c, describes implementation method three. Optional, Figure 5 The illustrated embodiment also includes step 502c. Step 502c can be performed after step 501 and before step 502.

[0263] 502c. The second communication device sends a third activation signaling to the first communication device. Correspondingly, the first communication device receives the third activation signaling from the second communication device.

[0264] The third activation signaling is used to activate the reference signal resources of a candidate cell. For example, the third activation signaling is used to activate the reference signal resources of one of P candidate cells. Optionally, the third activation signaling includes the identifier of the candidate cell.

[0265] Optionally, the second activation signaling is MAC CE.

[0266] In this implementation, the third activation signaling activates reference signal resources at the candidate cell level, which helps to improve the activation efficiency of reference signal resources and reduce activation signaling overhead.

[0267] Optionally, if the first reference signal resource group includes some or all of the reference signal resources of the candidate cell, then it means that some or all of the reference signal resources in the first reference signal resource group are activated.

[0268] Optionally, the reference signal resources in the first reference signal resource group belong to the reference signal resources of N candidate cells, where N is an integer greater than or equal to 2. Each of the N candidate cells corresponds one-to-one with one of the N third activation signaling messages. That is, the second communication device can activate the reference signal resources of these N candidate cells through the N third activation signaling messages, thereby activating all reference signal resources in the first reference signal resource group.

[0269] Optionally, some possible bearer methods for N third activation signaling are described below.

[0270] 1. N third activation signaling messages are carried in the same downlink signaling. For example, the downlink signaling is a MAC PDU. These N second activation signaling messages can be sent to the first communication device simultaneously, ensuring that the resources in the N reference signal resource sets are activated simultaneously.

[0271] 2. N third activation signaling messages occupy the same time-domain resources. This means the second communication device sends these N third activation signaling messages simultaneously. For example, the N third activation signaling messages are carried in one PUSCH. These N third activation signaling messages can be sent simultaneously to the first communication device, ensuring that the resources in the N reference signal resource sets are activated or deactivated simultaneously.

[0272] 3. The time-domain resources occupied by the N third-activation signaling messages are located within the same time period. This time period includes one or more time units. For example, the time unit can be a time-domain symbol, time slot, subframe, frame, millisecond, or second, etc., and this application does not specify the specific unit. For example, the N third-activation signaling messages include third-activation signaling 1 and third-activation signaling 2. Third-activation signaling 1 is carried on PUSCH1, and third-activation signaling 2 is carried on PUSCH2. PUSCH1 occupies time slots 1 and 2, while PUSCH2 occupies time slots 3 and 4. This time period is the time interval between time slots 1 and 4.

[0273] Optionally, for implementation methods two and three above, the communication protocol stipulates that at any given time, all reference signal resources in the first reference signal resource group must either be fully activated or completely deactivated. It is not permissible to activate only a portion of the reference signal resources in the first reference signal resource group.

[0274] Optionally, for the above implementation methods two and three, the communication protocol stipulates that at any time, the number K of candidate cells to which the activated reference signal resources in the first reference signal resource group belong is greater than or equal to the number L of candidate cells to be reported configured in the reporting configuration.

[0275] Specifically, the second communication device activates some or all of the reference signal resources in the first reference signal resource group for the first communication device. Then, the first communication device measures the activated reference signal resources in the first reference signal resource group.

[0276] 502. The first communication device sends the measurement results, which are the measurement results corresponding to the first reference signal resource group.

[0277] The measurement results include the measurement results of at least one candidate cell. The measurement results of each candidate cell include the measurement results of the reference signals corresponding to the M reference signal resources of the candidate cell. The M reference signal resources are some or all of the reference signal resources of the candidate cell in the first reference signal resource group. The at least one candidate cell belongs to P candidate cells, where M is a positive integer.

[0278] In one possible implementation, the measurement results include L*M reference signal resource index fields and L*M signal quality indication fields, where L and M are both positive integers. L is the number of candidate cells to be reported configured in the reporting configuration. The effective reference signal resources included in the first reference signal resource group belong to K candidate cells, where K candidate cells belong to P candidate cells, and K is a positive integer. The effective reference signal resources are the reference signal resources in the first reference signal resource group that can be used for measurement, such as configured periodic reference signal resources or activated semi-persistent reference signal resources.

[0279] In this implementation, two possible solutions will be introduced below, taking into account the relationship between K and L.

[0280] Option 1: When K is less than L, the first K*M reference signal resource index fields of the L*M reference signal resource index fields are used to indicate the indices of the M reference signal resources corresponding to the K candidate cells respectively; the first K*M signal quality indicator fields of the L*M signal quality indicator fields are used to indicate the signal quality of the M reference signal resources corresponding to the K candidate cells respectively; the last (LK)*M reference signal resource index fields of the L*M reference signal resource index fields are reserved fields, or all 0 fields, or all 1 fields; the last (LK)*M signal quality indicator fields of the L*M signal quality indicator fields are reserved fields, or all 0 fields, or all 1 fields. Reserved fields indicate that the field has no actual meaning and can be ignored by network devices. All 0 fields mean that all bits of the field are set to 0. All 1 fields mean that all bits of the field are set to 1. In other words, in the reporting format, the bits of the first K*M reference signal resource index fields and the first K*M signal quality indicator fields indicate specific information, while the bits corresponding to the last (LK)*M reference signal resource index fields and the last (LK)*M signal quality indicator fields are all filled with bit values ​​0 or 1. Alternatively, the last (LK)*M signal quality indicator fields in the L*M signal quality indicator fields indicate special values, such as 2. x -1. Where x is the length of a signal quality indicator field, i.e., the number of bits included in a signal quality indicator field. The signal quality indicator field indicates 2. x -1 means that all bits in the signal quality indicator field are filled with a bit value of 1.

[0281] The above method ensures that the number of bits corresponding to the measurement result remains constant, reducing the complexity of network devices receiving the measurement result. For example, the measurement result includes the contents shown in Table 5. The reference signal resource is the CSI-RS resource.

[0282] Table 5

[0283]

[0284]

[0285] In this implementation, after receiving the measurement results, the network device can determine the indices of the M reference signal resources corresponding to the K candidate cells using the first K*M reference signal resource index fields from the L*M reference signal resource index fields. The network device then determines the signal quality of the M reference signal resources corresponding to the K candidate cells using the first K*M signal quality indication fields from the L*M signal quality indication fields and the indices of the M reference signal resources corresponding to the K candidate cells. Optionally, the network device may ignore the last (LK)*M reference signal resource index fields from the L*M reference signal resource index fields, and also ignore the last (LK)*M signal quality indication fields from the L*M signal quality indication fields.

[0286] Optionally, when K is greater than or equal to L, the L*M reference signal resource index fields are used to indicate the indices of the M reference signal resources corresponding to the L candidate cells, and the L*M signal quality indicator fields are used to indicate the signal quality of the M reference signal resources corresponding to the L candidate cells. The L candidate cells belong to the K candidate cells, where M is a positive integer. For example, the L candidate cells are the L candidate cells with the highest average signal quality among the K candidate cells.

[0287] In another possible implementation, the effective reference signal resources included in the first reference signal resource group belong to K candidate cells, and the K candidate cells belong to P candidate cells, where K is a positive integer. Please refer to the aforementioned introduction regarding effective reference signal resources.

[0288] In this implementation, two possible solutions will be introduced below, taking into account the relationship between K and L.

[0289] Option 1: When K is greater than or equal to L, the measurement results include L*M reference signal resource index fields and L*M signal quality indication fields. The L*M reference signal resource index fields are used to indicate the indexes of the M reference signal resources corresponding to the L candidate cells respectively. The L*M signal quality indication fields are used to indicate the signal quality of the M reference signal resources corresponding to the L candidate cells respectively. The L candidate cells belong to K candidate cells, where M is a positive integer.

[0290] Option 2: When K is less than L, the measurement results include K*M reference signal resource index fields and K*M signal quality indication fields. The K*M reference signal resource index fields are used to indicate the indexes of the M reference signal resources corresponding to the K candidate cells respectively, and the K*M signal quality indication fields are used to indicate the signal quality of the M reference signal resources corresponding to the K candidate cells respectively, where M is a positive integer.

[0291] It should be noted that there are two main reasons why K is less than L. One is that the number P of candidate cells to which the reference signal resources configured in the first reference signal resource group belong is less than L. In other words, the first reference signal resource group only includes reference signal resources of K candidate cells. That is, K = P. The other is that the number of candidate cells to which the activated reference signal resources in the first reference signal resource group belong is less than L. In other words, only the reference signal resources of K candidate cells in the first reference signal resource group are activated.

[0292] In the above technical solution, the first communication device receives a reference signal resource configuration. The reference signal resource configuration is used to indicate a first reference signal resource group, which includes some or all of the reference signal resources of P candidate cells, where P is a positive integer. Therefore, the first communication device receives the reference signal resource configuration. The reference signal resource configuration is used to indicate a first reference signal resource group, which includes some or all of the reference signal resources of P candidate cells. This implements the configuration of reference signal resources for candidate cells for the first communication device. Further, the first reference signal resource group satisfies at least one of the following: when the first reference signal resource group includes the first reference signal resource of the first candidate cell, the first reference signal resource group includes all reference signal resources in the reference signal resource set where the first reference signal resource is located, and the first candidate cell is one of the P candidate cells; when the first reference signal resource group includes the first reference signal resource of the first candidate cell, the first reference signal resource group includes all the reference signal resources of the first candidate cell; or, when the first reference signal resource group includes the reference signal resources of multiple candidate cells, the first configuration parameters corresponding to the reference signal resources of the multiple candidate cells are the same, and the multiple candidate cells are some or all of the P candidate cells. The configuration constraints of the reference signal resources in the first reference signal resource group are defined. This helps terminal devices to better measure the signal quality of each candidate cell and provide corresponding measurement results to network devices, facilitating network devices to instruct terminal devices to switch to a suitable candidate cell, thereby improving communication transmission performance.

[0293] The following is a schematic diagram of the communication device according to an embodiment of this application. Please refer to...

[0300] It should be noted that the communication device 600 may include a transmitting module but not a receiving module.

[0310] Optionally, when the communication device 600 is a circuit or chip in a terminal device responsible for communication functions, such as a modem chip or a SoC chip or SIP chip containing a modem core, the function of the processing module 602 can be implemented by a circuit system in the aforementioned chip that includes one or more processors or processing cores.

[0312] This application also provides a communication device 700. Please refer to... Figure 7 The communication device 700 includes a processor 710 coupled to a memory 720 for storing computer programs or instructions and / or data. The processor 710 executes the computer programs or instructions and / or data stored in the memory 720, causing the methods in the above method embodiments to be executed. The communication device 700 is used to implement the operations performed by the first communication device or the second communication device in the above method embodiments.

[0313] Optionally, the communication device 700 may include one or more processors 710.

[0314] Optional, such as Figure 7 As shown, the communication device 700 may also include a memory 720.

[0315] Optionally, the communication device 700 may include one or more memory 720s.

[0316] Optionally, the memory 720 can be integrated with the processor 710 or set separately.

[0318] This application also provides a communication device 800, which can be a terminal device, a processor in the terminal device, or a chip. The communication device 800 can be used to perform the operations performed by the first communication device in the above method embodiments.

[0319] When the communication device 800 is a terminal device Figure 8 A simplified structural diagram of a terminal device is shown. (For example...) Figure 8 As shown, the terminal device includes a processor, a memory, and a transceiver. The memory can store computer program code, and the transceiver includes a transmitter 831, a receiver 832, radio frequency circuitry (not shown in the figure), an antenna 833, and input / output devices (not shown in the figure).

[0320] The processor is mainly used to process communication protocols and communication data; control terminal devices; execute software programs; and process data from software programs.

[0321] Memory is mainly used to store software programs and data.

[0322] Radio frequency (RF) circuits are mainly used for the conversion between baseband signals and RF signals, as well as for the processing of RF signals.

[0323] Antennas are primarily used for transmitting and receiving radio frequency signals in the form of electromagnetic waves.

[0324] Input / output devices can include touchscreens, displays, or keyboards. They are primarily used to receive user input and output data to the user. It should be noted that some types of terminal devices may not have input / output devices.

[0325] When data needs to be transmitted, the processor performs baseband processing on the data to be transmitted and outputs a baseband signal to the radio frequency (RF) circuit. The RF circuit then processes the baseband signal and transmits it outwards as electromagnetic waves via an antenna. When data is sent to the terminal device, the RF circuit receives the RF signal through the antenna. The RF circuit converts the RF signal back into a baseband signal and outputs it to the processor. The processor converts the baseband signal back into data and processes that data. For ease of explanation, Figure 8Only one memory, processor, and transceiver are shown in the illustration. In actual terminal devices, there may be one or more processors and one or more memories. Memory may also be referred to as storage medium or storage device, etc. Memory may be set up independently of the processor or integrated with the processor; this application does not limit this.

[0326] In this embodiment, the antenna and radio frequency circuit with transceiver function can be regarded as the transceiver module of the terminal device, and the processor with processing function can be regarded as the processing module of the terminal device.

[0327] like Figure 8 As shown, the terminal device includes a processor 810, a memory 820, and a transceiver 830. The processor 810 can also be referred to as a processing unit, processing board, processing module, or processing device. The transceiver 830 can also be referred to as a transceiver unit, transceiver, or transceiver device.

[0328] Optionally, the device in transceiver 830 used to implement the receiving function can be considered a receiving module, and the device in transceiver 830 used to implement the transmitting function can be considered a transmitting module. That is, transceiver 830 includes a receiver and a transmitter. A transceiver may also be called a transceiver unit, transceiver module, or transceiver circuit, etc. A receiver may also be called a receiver unit, receiving module, or receiving circuit, etc. A transmitter may also be called a transmitter, transmitting module, or transmitting circuit, etc.

[0329] Processor 810 is used to perform the above Figure 5 The illustrated embodiment shows the processing actions on the terminal device side. The transceiver 830 is used to perform the above-described actions. Figure 5 The embodiment shown illustrates the sending and receiving actions on the terminal device side.

[0332] This application also provides a communication device 900, which can be a network device or a chip. The communication device 900 can be used to perform the above-described... Figure 5The operation performed by the second communication device in the illustrated embodiment.

[0333] When the communication device 900 is a network device, such as a base station. Figure 9 A simplified schematic diagram of a base station structure is shown. The base station includes sections 910, 920, and 930.

[0334] The 910 section is mainly used for baseband processing and controlling the base station; the 910 section is usually the control center of the base station, which can be called the processor, and is used to control the base station to perform the processing operations on the second communication device side in the above method embodiment.

[0335] Section 920 is primarily used to store computer program code and data.

[0336] Section 930 is primarily used for transmitting and receiving radio frequency (RF) signals, as well as converting RF signals to baseband signals. Section 930 is commonly referred to as a transceiver module, transceiver, transceiver circuit, or transceiver unit. The transceiver module of section 930, also known as a transceiver or transceiver unit, includes antenna 933 and RF circuitry (not shown in the figure), where the RF circuitry is mainly used for RF processing. Optionally, the device in section 930 that performs the receiving function can be considered a receiver, and the device that performs the transmitting function can be considered a transmitter; that is, section 930 includes receiver 932 and transmitter 931. The receiver can also be called a receiving module, receiver circuit, or receiving circuit, and the transmitter can be called a transmitting module, transmitter, or transmitting circuit.

[0337] Sections 910 and 920 may include one or more circuit boards, each of which may include one or more processors and one or more memories. The processors are used to read and execute programs from the memories to implement baseband processing functions and control the base station. If multiple circuit boards exist, they can be interconnected to enhance processing capabilities. As an alternative implementation, multiple circuit boards may share one or more processors, multiple circuit boards may share one or more memories, or multiple circuit boards may simultaneously share one or more processors.
