Description

Technical Field

[0001] The present application belongs to the field of communication technology, and specifically relates to a communication method, device and storage medium. Background Art

[0002] In order to achieve downlink synchronization, the network usually needs to configure a synchronization signal block (synchronization signal and physical broadcast channel block, SSB) for each cell, and the user equipment (user equipment, UE) needs to obtain the frequency of the access carrier by searching and detecting the SSB.

[0003] In order to save network power consumption, the network expects not to configure SSB for each cell. For example, in carrier aggregation, only the primary cell is configured with SSB, and other secondary cells are not configured with SSB.

[0051] In order to make the purpose, technical solution and advantages of the embodiments of the present application clearer, the technical solution in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of this application.

[0052] The term "and / or" in this application describes the association relationship of associated objects, indicating that three relationships may exist. For example, A and / or B can represent: A exists alone, A and B exist at the same time, and B exists alone. The character " / " generally indicates that the associated objects before and after are in an "or" relationship.

[0053] In this application, "at least one of the following items" or similar expressions refer to any combination of these items, including any combination of single items or plural items. For example, at least one of a, b, or c can represent: a, b, c, a and b, a and c, b and c, or a, b and c, where each of a, b, and c can be an element itself or a set containing one or more elements.

[0054] The term "at least one" in the present application means one or more. "Plurality" means two or more.

[0055] The first, second, etc. descriptions that appear in this application are only used for illustration and distinction of the described objects, and there is no order, nor does it indicate a special limitation on the number of objects in the embodiments of this application, and cannot constitute any limitation on the embodiments of this application. For example, the first cell is the cell to be measured, and the second cell is the reference cell. The first cell and the second cell are used only to distinguish between different cells, and do not indicate the difference in priority or importance of the two types of cells.

[0056] In this application, "exemplary", "in some embodiments", "in other embodiments", etc. are used to indicate examples, illustrations, or descriptions. Any embodiment or design described as "exemplary" in this application should not be interpreted as being more preferred or more advantageous than other embodiments or designs. Specifically, the use of the word "exemplary" is intended to present concepts in a concrete way.

[0057] In order to explain the present application more clearly, the relevant technologies involved in the present application are first introduced below.

[0058] In a wireless network, a UE can communicate with multiple base stations, i.e. dual-connectivity (DC) or multi-connectivity (MC), where DC can also be called multi-radiodual connectivity (MR-DC) and MC can also be called multi-radio multiconnectivity (MR-DC). Specifically, the UE can connect to a master node (MN) and at least one secondary node (SN), the MN provides the UE with a primary cell (PCell), the SN provides the UE with a primary secondary cell (PSCell), and the MN has control plane signaling interaction with the core network. Using DC or MC, the UE can obtain communication services through the resources of multiple base stations, thereby performing high-speed data transmission.

[0059] UE can receive services from multiple cells at the same time under one base station, so the service cell group provided by MN for UE can also be called master cell group (MCG). Similarly, the service cell group provided by SN for UE is called secondary cell group (SCG). Among them, a MN can provide one or more MCGs, and a SN can provide one or more SCGs. An MCG contains at least one cell, and an SCG also contains at least one cell. When an MCG contains only one cell, the cell is the primary cell (PCell) of the UE. When an SCG contains only one cell, the cell is the primary secondary cell (PSCell) of the UE. In the NR system, PCell and PSCell can be collectively referred to as special cells (SpCell). When an MCG or an SCG contains multiple cells, each of which has a SpCell, and the cells except SpCell are called secondary cells (SCell). At this time, the SCell in each cell group is carrier aggregated with the SpCell to jointly provide services for the UE.

[0060] PCell is a serving cell located on the primary carrier. The UE performs the initial connection establishment process or starts the connection reestablishment process in the PCell. During the handover process, the PCell is indicated as the primary cell.

[0061] PSCell, a cell belonging to SCG, is the cell that the UE initially accesses during the process of establishing MR-DC.

[0062] SCell is a serving cell located on a secondary carrier. Once a radio resource control (RRC) connection is established, the SCell may be configured to provide additional radio resources.

[0063] In order to save network power consumption, the network expects not to configure SSB for each cell. For example, in carrier aggregation, only the primary cell is configured with SSB, and other secondary cells are not configured with SSB. The UE can obtain downlink synchronization information or quasi co-location based on the SSB of the primary cell. This information can be used as downlink synchronization information or QCL of the secondary cell.

[0064] In actual deployment, the network needs to know which cells can obtain synchronization information or QCL based on the SSB of the primary cell. Currently, the UE has not yet defined how to detect synchronization deviation between different cells.

[0065] In order to solve the above technical problems, the present application allows the UE to measure the synchronization deviation between different cells and then report the measurement report to the network device so that the network device can flexibly deploy secondary cells that do not send SSB.

[0066] The technical solution shown in the present application is described in detail below through specific embodiments. It should be noted that the following embodiments can exist independently or in combination with each other, and the same or displayed content will not be repeatedly described in different embodiments.

[0067] Figure 1 A flow chart of a communication method provided in an embodiment of the present application. Figure 1 As shown, the method includes:

[0068] S101. A UE generates a measurement report, where the measurement report is used to indicate a difference in a radio channel characteristic parameter between each first cell and a second cell in at least one first cell.

[0069] Before the UE generates a measurement report, the UE accesses the primary cell, establishes an RRC connection, and carries out services.

[0070] The UE can establish multiple services and corresponding data radio bearers (DRBs), and different DRBs have different service requirements.

[0071] The first cell may refer to a cell for which it is to be determined whether SSB needs to be transmitted.

[0072] In a possible implementation manner, the first cell may include: a secondary cell and / or a non-serving cell.

[0073] The at least one first cell may refer to at least one secondary cell, or at least one non-serving cell, or at least one secondary cell and at least one non-serving cell.

[0074] The UE may measure all or part of the SSBs of the first cell.

[0075] The second cell may refer to a cell determined to need to transmit the SSB.

[0076] In a possible implementation manner, the second cell may include: a primary cell, a primary secondary cell, or a secondary cell.

[0077] The UE may measure all or part of the SSBs of the second cell.

[0078] In a possible implementation manner, at least one first cell and a second cell have different frequencies.

[0079] Exemplarily, if there are two first cells, namely cell 1 and cell 2, and the second cell is cell A, then the frequencies of cell 1 and cell 2 are different from those of cell A.

[0080] In a possible implementation manner, the difference in radio channel characteristic parameters between each first cell and the second cell in at least one first cell may refer to the difference in radio channel characteristic parameters between each first cell and the second cell on the same beam index.

[0081] For example, if there is only one first cell, the UE can measure the wireless channel characteristic parameters of the first cell on SSB3 and SSB4, and the UE can measure the wireless channel characteristic parameters of the second cell on SSB1, SSB2, SSB3 and SSB4, then the difference in the wireless channel characteristic parameters between the first cell and the second cell may refer to the difference between the wireless channel characteristic parameters of the first cell on SSB3 and the wireless channel characteristic parameters of the second cell on SSB3, as well as the difference between the wireless channel characteristic parameters of the first cell on SSB4 and the wireless channel characteristic parameters of the second cell on SSB4.

[0082] In a possible implementation manner, the wireless channel characteristic parameter includes at least one of the following: Doppler shift, Doppler spread, and average delay.

[0083] That is, the measurement report can be used to indicate the difference in Doppler frequency shift between each first cell and the second cell in at least one first cell, and can also be used to indicate the difference in Doppler spread between each first cell and the second cell in at least one first cell. It can also be used to indicate the difference in average delay between each first cell and the second cell in at least one first cell, and can also be used to indicate the difference in Doppler frequency shift and the difference in average delay between each first cell and the second cell in at least one first cell, and can also be used to indicate the difference in Doppler spread and the difference in average delay between each first cell and the second cell in at least one first cell, and can also be used to indicate the difference in Doppler frequency shift and the difference in Doppler spread between each first cell and the second cell in at least one first cell, and can also be used to indicate the difference in Doppler frequency shift, the difference in Doppler spread and the difference in average delay between each first cell and the second cell in at least one first cell.

[0084] In one possible implementation, the difference in wireless channel characteristic parameters includes at least one of the following: Doppler frequency shift is greater than or equal to a preset Doppler frequency shift threshold, Doppler spread is greater than or equal to a preset Doppler spread threshold, and average delay is greater than or equal to a preset delay threshold; or, the difference in wireless channel characteristic parameters includes at least one of the following: Doppler frequency shift is less than a preset Doppler frequency shift threshold, Doppler spread is less than a preset Doppler spread threshold, and average delay is less than a preset delay threshold.

[0085] The Doppler frequency shift being greater than or equal to a preset Doppler frequency shift threshold may mean that an absolute value of a difference between the Doppler frequency shifts of each first cell and the second cell is greater than or equal to a preset Doppler frequency shift threshold.

[0086] The Doppler frequency shift being less than a preset Doppler frequency shift threshold may mean that an absolute value of a difference between the Doppler frequency shifts of each first cell and the second cell is less than a preset Doppler frequency shift threshold.

[0087] The Doppler spread being greater than or equal to a preset Doppler spread threshold may mean that an absolute value of a difference between the Doppler spreads of each first cell and the second cell is greater than or equal to the preset Doppler spread threshold.

[0088] The Doppler spread being smaller than a preset Doppler spread threshold may mean that an absolute value of a difference between the Doppler spreads of each first cell and the second cell is smaller than a preset Doppler spread threshold.

[0089] The average delay being greater than or equal to the preset delay threshold may mean that the absolute value of the difference between the average delay of each first cell and the second cell is greater than or equal to the preset delay threshold.

[0090] The average delay being less than the preset delay threshold may mean that the absolute value of the difference between the average delay of each first cell and the average delay of the second cell is less than the preset delay threshold.

[0091] Exemplarily, if there is only one first cell, the UE can measure the Doppler shift of the first cell on SSB1, SSB2, SSB3 and SSB4, and the UE can measure the Doppler shift of the second cell on SSB1, SSB2, SSB3 and SSB4, then the difference in the wireless channel characteristic parameters between the first cell and the second cell may refer to: the absolute value of the difference between the Doppler shift of the first cell on SSB1 and the Doppler shift of the second cell on SSB1 is greater than or equal to the corresponding threshold, the absolute value of the difference between the Doppler shift of the first cell on SSB2 and the Doppler shift of the second cell on SSB2 is greater than or equal to the preset Doppler shift threshold, the absolute value of the difference between the Doppler shift of the first cell on SSB3 and the Doppler shift of the second cell on SSB3 is greater than or equal to the preset Doppler shift threshold, and the absolute value of the difference between the Doppler shift of the first cell on SSB4 and the Doppler shift of the second cell on SSB4 is greater than or equal to the preset Doppler shift threshold.

[0092] S102. The UE sends a measurement report to a network device.

[0093] In other words, the network device receives the measurement report sent by the UE.

[0094] S103. The network device determines, based on the measurement report, whether the first cell needs to be configured with SSB when serving as a secondary cell of the UE.

[0095] The UE in this step may be the same as or different from the UE in S101 and S102.

[0096] If the measurement report indicates that the Doppler frequency shift between the first cell and the second cell is greater than or equal to the preset Doppler frequency shift threshold, and / or the Doppler expansion is greater than or equal to the preset Doppler expansion threshold, and / or the average delay is greater than or equal to the preset delay threshold, then SSB needs to be configured when determining the first cell as the secondary cell of the UE.

[0097] If the measurement report indicates that the Doppler frequency shift between the first cell and the second cell is less than the preset Doppler frequency shift threshold, the Doppler spread is less than the preset Doppler spread threshold, and the average delay is less than the preset delay threshold, then there is no need to configure SSB when determining the first cell as the secondary cell of the UE.

[0098] exist Figure 1In the illustrated embodiment, the UE generates a measurement report, the measurement report is used to indicate the difference in radio channel characteristic parameters between each first cell and the second cell in at least one first cell, and sends the measurement report to the network device, and the network device determines whether the first cell needs to be configured with SSB when it is used as a secondary cell of the user equipment (which may be other user equipment) according to the measurement report. The synchronization difference between different cells is obtained through the UE to assist the network in determining which cells can be based on the SSB of the primary cell or the secondary cell on the adjacent frequency point as the synchronization reference.

[0099] Based on the above embodiments, Figure 2 The communication method of the present application is described in detail.

[0100] Figure 2 A flow chart of another communication method provided in an embodiment of the present application. Figure 2 As shown, the method includes:

[0101] S201. A network device sends indication information to a UE, where the indication information instructs measuring a radio channel characteristic parameter of a first cell at at least one frequency point.

[0102] In other words, the UE receives the indication information sent by the network device.

[0103] The indication information may indicate measuring at least one of a Doppler shift, a Doppler spread, and an average delay of the first cell at at least one frequency point.

[0104] In a possible implementation manner, the indication information further indicates a reporting condition, where the reporting condition includes: at least one wireless channel characteristic parameter is greater than or equal to its corresponding threshold and / or reporting period.

[0105] If the indication information indicates measuring the Doppler shift, Doppler spread and average delay of the first cell on at least one frequency point, the reporting condition may refer to: at least one of the Doppler shift, Doppler spread and average delay is greater than or equal to its corresponding threshold, and / or the reporting period.

[0106] The UE may report the measured difference in the radio channel characteristic parameters between each first cell and the second cell to the network device at intervals of a reporting period.

[0107] When two reporting conditions exist at the same time, the previous reporting condition can be given priority. For example, the reporting period is 200ms. If the UE receives the indication information and measures that the difference between the wireless channel characteristic parameters of a first cell and a second cell at an interval of 100ms is greater than or equal to the corresponding threshold, a measurement report can be generated and reported without waiting for 200ms to report.

[0108] The specific duration of the reporting cycle can be determined based on actual conditions, and this application does not limit this. For example, the reporting cycle can be 200ms.

[0109] The second cell may be configured through indication information or by default. The network device may explicitly indicate the second cell or by default, for example, for indication information configured on the primary base station side to measure the radio channel characteristic parameters of the first cell at at least one frequency point, the second cell is by default the primary cell; for indication information configured on the secondary base station side to measure the radio channel characteristic parameters of the first cell at at least one frequency point, the second cell is by default the primary and secondary cells.

[0110] S202: The UE generates a measurement report, where the measurement report is used to indicate a difference in a radio channel characteristic parameter between each first cell in at least one first cell and a second cell.

[0111] S203: The UE sends a measurement report to the network device.

[0112] S204. The network device determines, based on the measurement report, whether the first cell needs to be configured with SSB when serving as a secondary cell of the UE.

[0113] It should be noted that the execution process of S202 to S204 can refer to the execution process of S101 to S103, and will not be repeated here.

[0114] To facilitate understanding, specific examples are given below to illustrate the communication method of the present application in detail.

[0115] Example 1

[0116] (1) The network device sends indication information to UE1.

[0117] The indication information instructs UE1 to measure the Doppler shift, Doppler spread and average delay of the first cell at frequency 1. The indication information also indicates a reporting condition: at least one of the Doppler shift, Doppler spread and average delay is greater than or equal to its corresponding threshold.

[0118] (2) UE1 generates a measurement report.

[0119] UE1 receives the indication information and measures the SSB of the first cell on frequency 1. UE1 can measure SSB1, SSB2, SSB3 and SSB4 of the first cell on frequency 1. UE measures the Doppler shift, Doppler spread and average delay on the four SSBs, and compares the Doppler shift, Doppler spread and average delay with the Doppler shift, Doppler spread and average delay of the second cell on the same beam index measured by UE1. If the absolute values ​​of the differences in the Doppler shift, Doppler spread and average delay are all greater than the corresponding thresholds, UE1 can generate a measurement report, indicating in the measurement report that the Doppler shift, Doppler spread and average delay of the first cell and the second cell are greater than or equal to the corresponding thresholds, or indicating in the measurement report that the Doppler shift, Doppler spread and average delay of the first cell and the second cell on SSB1 are greater than or equal to the corresponding threshold.

[0120] (3) UE1 sends a measurement report to the network device.

[0121] (4) The network device determines, based on the measurement report, that the first cell needs to be configured with an SSB when serving as a secondary cell of UE1 or UE2.

[0122] Example 2:

[0123] (1) The network device sends indication information to UE1.

[0124] The indication information instructs UE1 to measure the Doppler shift (or Doppler spread, or average delay) of the first cell on frequency 1 and the first cell on frequency 2. The indication information also indicates a reporting condition: a reporting period.

[0125] (2) UE1 generates a measurement report.

[0126] UE1 receives the indication information and measures the SSB of the first cell on frequency 1 and the SSB of the first cell on frequency 2. UE1 can measure SSB1, SSB2, SSB3 and SSB4 of the first cell on frequency 1 and SSB3 and SSB4 of the first cell on frequency 2. UE1 measures the Doppler shift (or Doppler spread, or average delay) on the 6 SSBs, and compares the Doppler shift (or Doppler spread, or average delay) with the Doppler shift (or Doppler spread, or average delay) of the second cell measured by UE1 on the same beam index.

[0127] If the absolute value of the difference between the Doppler frequency shift (or Doppler spread, or average delay) of the first cell and the second cell on frequency point 1 is greater than or equal to the corresponding threshold, and the absolute value of the difference between the Doppler frequency shift (or Doppler spread, or average delay) of the first cell and the second cell on frequency point 2 is less than the corresponding threshold, UE1 can generate a measurement report, indicating in the measurement report that the Doppler frequency shift (or Doppler spread, or average delay) of the first cell and the second cell on frequency point 1 is greater than or equal to the corresponding threshold, and the Doppler frequency shift (or Doppler spread, or average delay) of the first cell and the second cell on frequency point 2 is less than the corresponding threshold, or the measurement report indicates that the Doppler frequency shift (or Doppler spread, or average delay) of the first cell and the second cell on frequency point 1 on SSB2 is greater than or equal to the corresponding threshold, and the Doppler frequency shift (or Doppler spread, or average delay) of the first cell and the second cell on frequency point 2 on SSB3 is less than the corresponding threshold.

[0128] (3) UE1 sends a measurement report to the network device at every reporting period.

[0129] (4) The network device determines, based on the measurement report, that when the first cell on frequency point 1 is used as a secondary cell of UE1 or UE2, SSB needs to be configured, and when the first cell on frequency point 2 is used as a secondary cell of UE, SSB does not need to be configured.
