Description

Technical Field

[0001] The present application relates to the field of communications, and in particular to a communication method and device. Background Art

[0002] In a communication system, a base station can increase system capacity by configuring carrier aggregation (CA). CA includes a primary carrier (PCC) and a secondary carrier (SCC). The cell corresponding to the PCC is called the primary cell (PCell), and the cell corresponding to the SCC is called the secondary cell (SCell).

[0003] After the base station adds an SCell through Radio Resource Control (RRC) signaling, it needs to send Media Access Control (MAC) information to the User Equipment (UE) to activate the added SCell. The base station and UE can send and receive data based on the SCell. During the SCell activation process, the UE needs to send SCell measurement information to the base station. When multiple SCells are activated at the same time, the UE will send measurement information of multiple SCells to the base station, which may cause SCell activation failure.

[0074] The network architecture and business scenarios described in the embodiments of the present application are intended to more clearly illustrate the technical solutions of the embodiments of the present application, and do not constitute a limitation on the technical solutions provided in the embodiments of the present application. A person of ordinary skill in the art can appreciate that with the evolution of the network architecture and the emergence of new business scenarios, the technical solutions provided in the embodiments of the present application are also applicable to similar technical problems.

[0075] It should be noted that the terms "first" and "second" in the specification, claims and drawings of the present application are used to distinguish different objects rather than to describe a specific order. In addition, the terms "including" and "having" and any variations thereof are intended to cover non-exclusive inclusions. For example, a process, method, system, product or device that includes a series of steps or units is not limited to the listed steps or units, but may optionally include steps or units that are not listed, or may optionally include other steps or units that are inherent to these processes, methods, products or devices.

[0076] It should be understood that in the embodiments of the present application, "terminal device (item)" refers to one or more, "multiple" refers to two or more, "at least two (items)" refers to two or three and more than three, and "and / or" is used to describe the association relationship of the associated objects, indicating that there can be three relationships. For example, "A and / or B" can represent: only A exists, only B exists, and A and B exist at the same time, where A and B can be singular or plural. The character " / " generally indicates that the objects associated with each other are in an "or" relationship. "At least one of the following items" or similar expressions refers 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 and b and c", where a, b, c can be single or multiple. It should be understood that in the embodiments of the present application, "B corresponding to A" means that B is associated with A. For example, B can be determined based on A. It should also be understood that determining B based on A does not mean determining B based only on A, but B can also be determined based on A and / or other information. In addition, the "connection" in the embodiments of the present application refers to various connection modes such as direct connection or indirect connection to achieve communication between devices, and the embodiments of the present application do not impose any limitation on this.

[0077] Unless otherwise specified, the "transmission" (transmit / transmission) appearing in the embodiments of the present application refers to bidirectional transmission, including sending and / or receiving actions. Specifically, the "transmission" in the embodiments of the present application includes the sending of data, the receiving of data, or the sending of data and the receiving of data. In other words, the data transmission here includes uplink and / or downlink data transmission. Data may include channels and / or signals, uplink data transmission is uplink channel and / or uplink signal transmission, and downlink data transmission is downlink channel and / or downlink signal transmission. The "network" and "system" appearing in the embodiments of the present application express the same concept, and the communication system is the communication network.

[0078] In a communication system, a base station can increase system capacity by configuring carrier aggregation. Carrier aggregation includes a main carrier and a secondary carrier. The cell corresponding to the main carrier is called a main cell, and the cell corresponding to the secondary carrier is called a secondary cell. After the base station adds an SCell through radio resource control signaling, it is necessary to send media access control information to the user terminal to activate the added SCell. The base station and the UE can send and receive data based on the SCell. After receiving the MAC activation signaling, the UE needs to feedback a hybrid automatic repeat request (HARQ) to the base station, and perform the activation process, and finally feedback channel state information (CSI) to the base station, which means that the SCell has completed the activation process.

[0079] SCell activation can be divided into SCell activation under Frequency Range 1 (FR1) and SCell activation under Frequency Range 2 (FR2). Compared with SCell activation under FR1, the SCell activation process under FR2 is more complicated. Specifically, the SCell activation process under FR1 includes cell search, automatic gain control (AGC), timing and other processes; and because of the involvement of beam information, the SCell activation process under FR2 includes more steps. In addition to the above-mentioned SCell activation process under FR1, SCell activation under FR2 also requires UE to perform beam scanning, so the number of reference signals required to be measured is doubled compared to SCell activation under FR1. For example, SCell activation under FR1 requires measuring 1 synchronization signal block (synchronization signal / pbch block, SSB) to complete the search for the cell, while SCell activation under FR2 requires beam scanning. Assuming that the scanning coefficient of beam scanning is 8 (scanning in 8 directions), 8 SSBs are required to complete the search for the cell. Therefore, the time required for SCell activation in FR2 is also longer than that in FR1.

[0080] SCell activation under FR2 is divided into known activation and unknown activation. In known activation, the base station already has measurement information of the SCell to be activated, and this measurement information can be used to activate the cell. In unknown activation, the base station does not have measurement information of the SCell to be activated, and cannot determine what measurement information to use to activate the SCell. In order to clarify what measurement information the base station uses to activate the SCell in unknown activation, when the UE receives the activation command, it can send the previous measurement information to the base station. After receiving the measurement information, the base station can use it to activate the SCell.

[0081] When multiple SCells are activated at the same time, since the UE measures each SCell in turn, measurement information of multiple component carriers (CCs) will be generated at different times. Figure 1As shown, CC1-CC4 are four carriers of the same FR2 band, and the base station configures measurements on all four carriers for the UE. The UE needs to measure CC1-CC4 in chronological order, so the measurement information of CC1-CC4 (i.e., the measurement information of the best beam) is generated at different times. The SSB index of the measurement information measured on CC1 is SSB#1, the SSB index of the measurement information measured on CC2 is SSB#1, the SSB index of the measurement information measured on CC3 is SSB#2, and the SSB index of the measurement information measured on CC4 is SSB#3. Due to the movement of the UE or the change of the channel, the SSB index of CC1-CC4 obtained at different times is different. At this time, the UE receives the activation command, and the UE reports the measurement information of all SCells, namely: SSB#1, SSB#1, SSB#2, and SSB#3. At this time, the base station cannot determine based on which SSB index the transmission configuration indicator (TCI) of the SCell to be activated should be configured.

[0082] exist Figure 1 In the example shown, CC4's measurement information SSB#3 is the latest measurement information before activation, and activating SCell based on this measurement information has better performance. However, for the base station, the order of the measurement information of multiple SCells received is unknown, and the base station cannot determine which is the latest measurement information. If the base station configures TCI based on older measurement information (for example, measurement information of CC1-CC3), it may cause activation failure or performance loss, affecting the performance of the carrier after activation.

[0083] It can be seen that when multiple SCells are activated at the same time, the UE will send measurement information of multiple SCells to the base station, which may cause the SCell activation to fail.

[0084] In order to solve the above technical problems, an embodiment of the present application provides a communication method. The method provided by the embodiment of the present application is described below in conjunction with the drawings in the specification.

[0085] The communication method provided in the embodiment of the present application can be applied to various communication systems, such as: long-term evolution (LTE) system, fifth generation (5G) mobile communication system, wireless fidelity (WiFi) system, future communication system, or a system integrating multiple communication systems, etc., which is not limited in the embodiment of the present application. Among them, 5G can also be called new radio (NR).

[0086] The communication method provided in the embodiments of the present application can be applied to various communication scenarios, for example, it can be applied to one or more of the following communication scenarios: enhanced mobile broadband (eMBB), ultra-reliable low latency communication (URLLC), machine type communication (MTC), massive machine type communication (mMTC), device to device (D2D), vehicle to everything (V2X), vehicle to vehicle (V2V), and Internet of things (IoT), etc.

[0087] Below Figure 2 Taking the communication system shown as an example, the communication method provided in the embodiment of the present application is described.

[0088] Figure 2 is a schematic diagram of a communication system provided in an embodiment of the present application, such as Figure 2 As shown, the communication system may include:

[0089] Network equipment and terminal equipment connected in communication. The network equipment can cover one main cell and multiple secondary cells. For example, the network equipment covers a main cell PCell and multiple secondary cells: SCell1, SCell2, and SCell3. In carrier aggregation, the main cell PCell is responsible for security, switching, and uplink physical control channel carrying. Other cells participating in the aggregation are called member cells or secondary cells SCell. SCell is responsible for data transmission and does not involve security, switching, etc. The terminal device can send measurement information for activating SCell to the network device, so that the network device can activate SCell based on the measurement information. After activating SCell, the network device and the terminal device can send and receive data based on SCell.

[0090] It should be noted that Figure 2 This is just an exemplary framework diagram. Figure 2 The number of cells and the status of the terminal equipment are not restricted. Figure 2 In addition to the functional nodes shown, other nodes may also be included, such as core network devices, gateway devices, application servers, etc., without limitation. The network devices communicate with the core network devices via wired or wireless means, such as communicating with each other via a next generation (NG) interface.

[0091] Among them, the network device is mainly used to implement at least one function of resource scheduling, wireless resource management, and wireless resource control of the terminal device. Specifically, the network device may include a base station, a wireless access point, a transceiver point (TRP), a transmission point (TP), and any other access node. In the embodiment of the present application, the device for implementing the function of the network device may be a network device; it may also be a device that can support the network device to implement the function, such as a chip system, which can be installed in the network device or used in combination with the network device. In the technical solution provided in the embodiment of the present application, the technical solution provided in the embodiment of the present application is described by taking the device for implementing the function of the network device as an example, which is a network device.

[0092] Terminal equipment may be user equipment (UE), mobile station (MS) or mobile terminal (MT), etc. Specifically, the terminal equipment may be a mobile phone, a tablet computer or a computer with wireless transceiver function, or a virtual reality (VR) terminal equipment, an augmented reality (AR) terminal equipment, a wireless terminal equipment in industrial control, a wireless terminal equipment in unmanned driving, a wireless terminal equipment in telemedicine, a wireless terminal equipment in a smart grid, a wireless terminal equipment in a smart city, a smart home, or a vehicle-mounted terminal equipment, etc. In the embodiment of the present application, the device for realizing the function of the terminal device may be a terminal device, or may be a device capable of supporting the terminal device to realize the function, such as a chip system, which may be installed in the terminal device or used in combination with the terminal device.

[0093] The communication system provided by the embodiment of the present application is introduced above. Based on the communication system, the embodiment of the present application provides a communication method, which is described below.

[0094] Figure 3 FIG. 1 is a flow chart of a communication method provided by an embodiment of the present application. Figure 3 As shown, the method may include the following steps:

[0095] S310, the network device sends first information to the terminal device, and correspondingly, the terminal device receives the first information from the network device.

[0096] Wherein, referring to the introduction of the communication system in this application, the network device is connected to the terminal device in communication, and data can be transmitted between the two, such as transmitting first information. The first information is used to indicate the secondary cell that needs to be activated. Specifically, the first information can indicate the activation of one secondary cell, or the first information can also indicate the activation of multiple secondary cells. Exemplarily, the first information can be media access control (MAC) information.

[0097] S320, the terminal device sends second information to the network device, and correspondingly, the network device receives the second information from the terminal device.

[0098] The second information includes multiple groups of measurement information of multiple secondary cells with the same secondary cell frequency band band (or the same frequency range) as indicated by the first information and indication information, and the indication information is used to indicate the target measurement information in the multiple groups of measurement information. Exemplarily, the indication information can be carried in the measurement identifier measID signaling. In another example, the indication information can also be carried in the newly established signaling without limitation.

[0099] Each group of measurement information includes information such as reference signal indication information (SSB index) and / or reference signal receiving power (RSRP). SSB index can be used to configure TCI to activate SCell, and information such as RSRP can be used for other configurations after the secondary cell is activated, which will not be described in detail. Among them, a set of measurement information may include one SSB index or multiple SSB indexes. For the case where the measurement information includes multiple SSB indexes, exemplarily, the multiple SSB indexes may be SSB#1 and SSB#2, or SSB#3 and SSB#4, etc. If there are multiple SSB indices in the target measurement information, the network device selects one of the SSB indices to activate the secondary cell.

[0100] The target measurement information is a set of measurement information that can successfully activate the secondary cell among multiple sets of measurement information. Considering that the later the measurement information is measured, the more it conforms to the current communication state of the secondary cell, the better the performance of activating the secondary cell based on the measurement information. Exemplarily, the target measurement information can be set to the latest set of measurement information measured among multiple sets of measurement information, and the secondary cell is activated based on the measurement information, with better performance. The latest measurement can refer to the latest measurement before the terminal device sends the second information, or it can also refer to the latest measurement before the terminal device receives the first information. The latest measurement can also be called the latest measurement, the last measurement, the final measurement, etc., without limitation.

[0101] In another example, the target measurement information can also be set to any set of measurement information in which the difference between the measurement time and the current time in the multiple sets of measurement information is less than a time threshold, and the time threshold can be set flexibly without restriction. The current time can refer to the time when the terminal device sends the second information, or it can also refer to the time when the terminal device receives the first information. Exemplarily, the time threshold can be set to 5ms. Although the target measurement information selected in this way may not be the latest set of measurement information measured in the multiple sets of measurement information, its measurement time is closer to the current time, and the secondary cell is activated based on this measurement information, and the activation performance is usually better.

[0102] The second information is further introduced below in conjunction with specific scenarios. For example, in a certain communication scenario, it is assumed that the network device covers four secondary cells: SCell1, SCell2, SCell3, and SCell4, wherein SCell1 and SCell2 are in the same frequency band band1, SCell3 and SCell4 are in the same frequency band band2, and the first information indicates activation of SCell1. The second information includes multiple groups of measurement information and indication information of multiple secondary cells that are the same as the secondary cell frequency band indicated by the first information. The second information includes measurement information and indication information of SCell1 and SCell2, and the indication information indicates a group of measurement information in the measurement information of SCell1 and SCell2, namely, the target measurement information.

[0103] Alternatively, the second information includes multiple groups of measurement information and indication information of multiple secondary cells in the same frequency range (Frequency Range, FR) as indicated by the first information. For example, assuming that the network device covers four secondary cells: SCell1, SCell2, SCell3, and SCell4, wherein SCell1 and SCell2 are both in FR1, SCell3 and SCell4 are both in FR2, and the first information indicates activation of SCell1, then the second information includes measurement information and indication information of SCell1 and SCell2, and the indication information indicates a group of measurement information in the measurement information of SCell1 and SCell2, namely, the target measurement information.

[0104] S330: The network device activates the secondary cell indicated by the first information according to the target measurement information.

[0105] Among them, after receiving the second information, the network device can determine the target measurement information in the second information according to the indication information in the second information, and activate the secondary cell indicated by the first information according to the target measurement information. The specific activation process is: configure TCI based on the SSB index in the target measurement information (including configuring the TCI of the physical downlink control channel PDCCH, configuring the TCI of the physical downlink shared channel PDSCH, and configuring the TCI of the channel state information reference signal CSI-RS); trigger the physical downlink control channel command random access (PDCCH order RACH) based on the SSB index in the target measurement information; configure the uplink spatial relation (UL spatial relation) based on the SSB index in the target measurement information.

[0106] Exemplarily, assuming that the network device receives the second information including four groups of measurement information and indication information, the SSB indexes in the four groups of measurement information are: SSB#1, SSB#1, SSB#2, SSB#3, and the indication information indicates that SSB#3 is the target measurement information, then the network device activates the secondary cell indicated by the first information according to SSB#3. That is, the secondary cell TCI and other information are configured according to SSB#3.

[0107] In an embodiment of the present application, while the terminal device sends multiple groups of measurement information of the SCell to the base station, it also sends indication information that can indicate the target measurement information in the multiple groups of measurement information, so that the base station can determine to activate the SCell based on the target measurement information, thereby ensuring the performance of SCell activation.

[0108] In one embodiment, the first information indicates activation of multiple secondary cells (the frequency bands or frequency ranges of the multiple secondary cells are different). In this embodiment, the activation of multiple secondary cells is introduced by taking the case where the first information indicates activation of two secondary cells (the first secondary cell and the second secondary cell) as an example. It should be understood that in a specific implementation, the first information may also indicate activation of three or more secondary cells, and the activation process thereof may refer to the activation process of two secondary cells, which will not be described in detail.

[0109] In this embodiment, when the first information indicates activation of two secondary cells (a first secondary cell and a second secondary cell), the multiple groups of measurement information include a first measurement information group (including multiple groups of measurement information of multiple secondary cells with the same frequency band as the first secondary cell) and a second measurement information group (including multiple groups of measurement information of multiple secondary cells with the same frequency band as the second secondary cell). Accordingly, the indication information indicates two target measurement information. Specifically, the indication information indicates the target measurement information in the first measurement information group (used to activate the first secondary cell) and the target measurement information in the second measurement information group (used to activate the second secondary cell).

[0110] Exemplarily, in a certain communication scenario, the network device covers four secondary cells: SCell1, SCell2, SCell3, and SCell4, wherein SCell1 and SCell2 are in the same frequency band band1 (or both are in FR1), SCell3 and SCell4 are in the same frequency band band2 (or both are in FR2), and the first information indicates activation of the first secondary cell SCell1 and the second secondary cell SCell3. The second information includes measurement information of SCell1 and SCell2 (i.e., the first measurement information group), measurement information of SCell3 and SCell4 (i.e., the second measurement information group), and indication information, wherein the indication information indicates that a group of measurement information in the measurement information of SCell1 and SCell2 is the target measurement information; the indication information also indicates that a group of measurement information in the measurement information of SCell3 and SCell4 is another target measurement information.

[0111] In the embodiment of the present application, the indication information indicates target measurement information of activated secondary cells in different bands, so that the base station can simultaneously activate secondary cells in different bands.

[0112] In one embodiment, the first information indicates activation of multiple secondary cells (multiple secondary cells have the same frequency band or the same frequency range). Since the frequency band of the multiple secondary cells is the same (or the same frequency range). At this time, for each secondary cell indicated for activation, the multiple secondary cells with the same frequency band as the secondary cell are consistent with the multiple secondary cells with the same frequency band as other secondary cells indicated for activation. Accordingly, the multiple groups of measurement information of each secondary cell indicated for activation are the same. Therefore, the same target measurement information can be applied to activate the multiple secondary cells indicated for activation. The specific activation process can refer to the description of S310-S330, which will not be repeated here.

[0113] In one embodiment, when configuring a measurement object (MO), the terminal device is limited to configuring one MO for one band.

[0114] In one embodiment, when the terminal device sends multiple groups of measurement information to the network device, it may simultaneously send the measurement timestamp of each group of measurement information, and the network device may select a group of measurement information with the latest measurement timestamp to activate the secondary cell.

[0115] The present application also provides a flow chart of another communication method. Figure 4 FIG. 1 shows a flow chart of the communication method. Figure 4 As shown, the method may include the following steps:

[0116] S410, the network device sends first information to the terminal device, and correspondingly, the terminal device receives the first information from the network device.

[0117] The first information is used to indicate activation of a secondary cell, and the first information may indicate activation of one secondary cell, or the first information may also indicate activation of multiple secondary cells. Exemplarily, the first information may be MAC information.

[0118] S420: The terminal device sends target measurement information to the network device. Correspondingly, the network device receives the target measurement information from the terminal device.

[0119] The target measurement information is determined from multiple groups of measurement information of multiple secondary cells with the same frequency band as the secondary cell indicated by the first information, and the target measurement information is used to activate the secondary cell indicated by the first information. If the first information indicates to activate one secondary cell, the target measurement information is a group. If the first information indicates to activate multiple secondary cells, and the multiple secondary cells indicated to be activated are in the same frequency band (or in the same frequency range), then for each secondary cell indicated to be activated, the multiple secondary cells with the same frequency band as the secondary cell are consistent with the multiple secondary cells with the same frequency band as other secondary cells indicated to be activated. Accordingly, the multiple groups of measurement information of each secondary cell indicated to be activated are the same, so the same group of target measurement information can be applied to activate the multiple secondary cells indicated to be activated. In this case, the target measurement information is still a group. If the first information indicates to activate multiple secondary cells, and at least two of the multiple secondary cells indicated to be activated are in different frequency bands (or in different frequency ranges), the multiple secondary cells indicated to be activated are in several frequency bands (or frequency ranges), and there are several groups of target measurement information.

[0120] For example, in a certain communication scenario, the network device covers four secondary cells: SCell1, SCell2, SCell3, and SCell4, wherein SCell1 and SCell2 are in the same frequency band band1 (or both in FR1), SCell3 and SCell4 are in the same frequency band band2 (or both in FR2), and the first information indicates activation of the first secondary cell SCell1 and the second secondary cell SCell3, then the target measurement information includes a set of measurement information determined from the measurement information of SCell1 and SCell2, and also includes a set of measurement information determined from SCell3 and SCell4. That is, indicating that the two activated secondary cells are in two frequency bands (or two frequency ranges), there are two sets of target measurement information.

[0121] S430: The network device activates the secondary cell indicated by the first information according to the target measurement information.

[0122] After receiving the target measurement information, the network device may activate the secondary cell indicated by the first information according to the target measurement information.

[0123] In the embodiment of the present application, the terminal device sends the target measurement information to the network device, and the network device can directly apply the target measurement information to activate the secondary cell, thereby ensuring the activation performance of the secondary cell.

[0124] In one embodiment, the target measurement information is set to a set of measurement information measured the latest among the multiple sets of measurement information.

[0125] Considering that the later the measurement information is measured, the more it conforms to the current communication state of the secondary cell, the better the performance of activating the secondary cell based on the measurement information. Exemplarily, the target measurement information is set to the latest set of measurement information among multiple sets of measurement information, and the secondary cell is activated based on the measurement information, which has better performance.

[0126] In an embodiment, the target measurement information may also be set to any set of measurement information in which the difference between the measurement time and the current time among the multiple sets of measurement information is less than a preset time threshold.

[0127] The time threshold can be set flexibly without restriction. For example, the time threshold can be set to 5ms. Although the target measurement information selected in this way may not be the latest set of measurement information measured among multiple sets of measurement information, its measurement time is closer to the current time, and the activation performance of the secondary cell is usually better when the secondary cell is activated based on the measurement information.

[0128] In an embodiment, the target measurement information may also be set as a combination of the first measurement information and the second measurement information.

[0129] Among them, the first measurement information is the latest measured among multiple groups of measurement information, and the second measurement information is at least one group of measurement information in the multiple groups of measurement information that has the same reference signal indication information SSB index as the first measurement information. For the network device, when activating the secondary cell, it is necessary to clearly configure which SSB to apply when TCI to activate the secondary cell, and SSBindex can indicate the SSB. In this embodiment, although the target measurement information includes multiple groups of measurement information, the SSB index in the multiple groups of measurement information is the same. When the base station receives the target measurement information, it can directly apply the SSB indicated by the SSB index to activate the secondary cell, and because the SSB index is the latest measured, the performance of activating the secondary cell is better.

[0130] Exemplarily, multiple groups of measurement information include: SCell 1: SSB#1, RSRP 100; SCell 2: SSB#1, RSRP102; SCell 3: SSB#3, RSRP 100; SCell 4: SSB#1, RSRP 110, among which, the measurement information of SCell 1 is measured latest, then the first measurement information is the measurement information of SCell 1: SSB#1, RSRP 100, the SSBindex of SCell 2 and SCell 4 is the same as that of SCell 1, both are SSB#1, then the second measurement information can be the measurement information of SCell 2 or the measurement information of SCell 4, and the second measurement information can also be the measurement information of SCell 2 and the measurement information of SCell 4.

[0131] In another example, multiple groups of measurement information include: SCell 1: SSB#1,2,3, RSRP 100; SCell 2: SSB#1,3, RSRP 102; SCell 3: SSB#3,4, RSRP 100; SCell 4: SSB#1,2, RSRP 110, where the measurement information of SCell 1 is the latest measured, and the first measurement information is the measurement information of SCell 1: SSB#1,2,3, RSRP 100, and the SSB index of SCell2 and SCell 4 is the same as that of SCell1 (the same here does not require the SSB index to be completely consistent, as long as other SSB indices can be used as subsets of the SSB index in the first measurement information, they are considered to be the same). SSB#1,2,3 includes SSB#1,3 and SSB#1,2, so the SSB index of SCell 2 and SCell 4 is considered to be the same as that of SCell1. The second measurement information may be the measurement information of SCell 2 or the measurement information of SCell 4. The second measurement information may also be the measurement information of SCell 2 and the measurement information of SCell 4.

[0132] In an embodiment, the target measurement information may also be set as a combination of the first measurement information and the third measurement information.

[0133] The first measurement information is the latest measured among the multiple groups of measurement information, and the third measurement information is part of the measurement information in at least one group of measurement information among the multiple groups of measurement information, and the part of the measurement information includes measurement information other than the reference signal indication information. In this embodiment, although the target measurement information includes multiple groups of measurement information, the multiple groups of measurement information include a unique SSB index (i.e., the SSB index in the first measurement information). When the base station receives the target measurement information, it applies the SSB indicated by the unique SSB index to activate the secondary cell, and because the SSB index is the latest measured, the performance of activating the secondary cell is better.

[0134] Exemplarily, the multiple groups of measurement information include: SCell 1: SSB#1, RSRP 100; SCell 2: SSB#1, RSRP 102; SCell 3: SSB#3, RSRP 100; SCell 4: SSB#1, RSRP 110, wherein the measurement information of SCell 1 is the latest measured, and the first measurement information is the measurement information of SCell 1: SSB#1, RSRP 100. The third measurement information is the information after removing the SSB index from at least one group of measurement information of SCell 2, SCell 3, and SCell 4.

[0135] The present application embodiment also provides a flow chart of another communication method, which is different from Figure 3 or Figure 4 In the communication method shown, the target measurement information for activating the secondary cell is determined by the terminal device, while the target measurement information is determined by the network device. Figure 5 FIG. 1 shows a flow chart of the communication method. Figure 5 As shown, the method may include the following steps:

[0136] S510, the network device sends first information to the terminal device; correspondingly, the terminal device receives the first information,

[0137] The first information is used to indicate activation of a secondary cell, and the first information may indicate activation of one secondary cell, or the first information may also indicate activation of multiple secondary cells. Exemplarily, the first information may be MAC information.

[0138] S520, the terminal device sends multiple groups of measurement information to the network device; correspondingly, the network device receives the multiple groups of measurement information.

[0139] The multiple groups of measurement information are multiple groups of measurement information of multiple secondary cells with the same frequency band as the secondary cell indicated by the first information. For example, in a certain communication scenario, it is assumed that the network device covers four secondary cells: SCell1, SCell2, SCell3, and SCell4, wherein SCell1 and SCell2 are in the same frequency band band1, SCell3 and SCell4 are in the same frequency band band2, and the first information indicates activation of SCell1, then the multiple groups of measurement information include measurement information of SCell1 and SCell2.

[0140] S530: The network device determines target measurement information from multiple groups of measurement information.

[0141] Referring to the introduction of S420, based on the different secondary cells indicated by the first information, the target measurement information may be one group or multiple groups, which will not be described in detail here. When the network device determines the target measurement information, the measurement information of the target secondary cell in the multiple secondary cells may be determined as the target measurement information.

[0142] In one embodiment, the target secondary cell is a secondary cell configured with a physical uplink control channel PUCCH (PUCCH SCell).

[0143] Among them, if the terminal device is configured with PUCCH SCell, compared with other SCells, the terminal device will measure PUCCH SCell with a smaller measurement period. Therefore, the measurement information of PUCCH SCell is likely to be the latest measurement information. The performance of activating SCell based on the measurement information of PUCCH SCell is better.

[0144] In one embodiment, the frequency of the target secondary cell is used to measure neighboring cells of the terminal device.

[0145] Among them, if multiple same-frequency measurements are configured in one band of FR2, the terminal device is only required to measure the neighboring cells and the secondary cells of the terminal device at the same time on one secondary carrier SCC (also called frequency point), and only the secondary cells need to be measured on other secondary carrier SCCs. The measurement period of the frequency point for measuring the neighboring cells and the secondary cells at the same time is generally short, so the measurement information of the secondary cell measured at the frequency point is most likely the latest measurement information, and the performance of activating the SCell based on the measurement information of the secondary cell measured at the frequency point is better.

[0146] In an embodiment, the measurement cycle of the target secondary cell is the shortest among multiple measurement cycles of multiple secondary cells.

[0147] Among them, the network device includes configuring MeasCycleSCell in the measurement of SCell configuration, and the terminal device will measure SCell according to the configured MeasCycleSCell (for example, once every 160ms, once every 320ms, etc.). Therefore, the shorter the MeasCycleSCell, the shorter the measurement period of SCell. The measurement information of the secondary cell configured with the shortest MeasCycleSCell is most likely to be measured last. At this time, the secondary cell configured with the shortest MeasCycleSCell is the target secondary cell.

[0148] In addition to MeasCycleSCell, the measurement period of the secondary cell may also be affected by other factors. Table 1 shows the factors that affect the measurement period.

[0149] Table 1

[0150]

[0151] Among them, under different discontinuous reception cycle configurations, the formula for determining the measurement period is also different. For details, please refer to the product of several parameters in the formula in Table 1. CSSFintra is the intra-frequency carrier specific scaling factor, and Mmeas_period_w / o_gaps is a set of measurement parameters. For the parameters CSSFintra, DRX cycle, and Mmeas_period_w / o_gaps, the smaller the value, the shorter the measurement period of the SCell, and the measurement information of the secondary cell configured with the minimum parameter product is most likely to be measured last. At this time, the secondary cell configured with the minimum parameter product is the target secondary cell.

[0152] After determining the target measurement information based on any one of the embodiments in S530 above, the network device may activate the secondary cell indicated by the first information according to the target measurement information, that is, execute S540:

[0153] S540: The network device activates the secondary cell indicated by the first information according to the target measurement information.

[0154] After determining the target measurement information, the network device can activate the secondary cell indicated by the first information according to the target measurement information. Specifically, the network device can configure TCI using the SSB indicated by the SSB index in the target measurement information to activate the secondary cell.

[0155] In an embodiment of the present application, by configuring a rule for determining target measurement information in a network device, the network device independently determines the target measurement information for activating the secondary cell application, without requiring any signaling modification on the terminal device side, thereby reducing protocol impact and ensuring the activation performance of the secondary cell.

[0156] The above mainly introduces the scheme provided by the embodiment of the present application from the perspective of the execution logic of each step. It is understandable that each node, such as a terminal device, includes a hardware structure and / or software module corresponding to each function in order to realize the above functions.
