Description

Communication method and device Technical Field

[0001] The present application relates to the field of communications, and in particular to communication methods and devices. 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 activating multiple SCells simultaneously, the UE will send measurement information for multiple SCells to the base station, which may cause SCell activation failure.

[0075] 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. Ordinary technicians in this field will know that with the evolution of network architecture and the emergence of new business scenarios, the technical solutions provided in the embodiments of the present application are also applicable to similar technical problems.

[0076] It should be noted that the terms "first" and "second" in the specification, claims, and drawings of this application are used to distinguish different objects, not 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 not listed, or may optionally include other steps or units inherent to such process, method, product, or device.

[0077] It should be understood that in the embodiments of the present application, "(item) of the terminal device" refers to one or more, "multiple" refers to two or more, "at least two (items)" refers to two or three and more, 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 mean: 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 associated objects before and after 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 mean: 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 solely on A; 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 methods, 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.

[0078] Unless otherwise specified, the "transmission" (transmit / transmission) appearing in the embodiments of the present application refers to bidirectional transmission, including the actions of sending and / or receiving. 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.

[0079] In a communication system, a base station can improve system capacity by configuring carrier aggregation. Carrier aggregation includes a primary carrier and a secondary carrier. The cell corresponding to the primary carrier is called a primary 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 needs 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. Finally, it needs to feedback channel state information (CSI) to the base station, which means that the SCell has completed the activation process.

[0080] SCell activation can be divided into SCell activation in Frequency Range 1 (FR1) and SCell activation in Frequency Range 2 (FR2). Compared to SCell activation in FR1, the SCell activation process in FR2 is more complex. Specifically, the SCell activation process in FR1 includes cell search, automatic gain control (AGC), timing, and other processes. However, because beam information is involved, the SCell activation process in FR2 includes more steps. In addition to the SCell activation process in FR1, SCell activation in FR2 also requires the UE to perform beam scanning. Therefore, the number of reference signals required for measurement increases exponentially compared to SCell activation in FR1. For example, SCell activation in FR1 requires measuring one synchronization signal block (SSB) to complete the cell search, while SCell activation in FR2 requires beam scanning. Assuming the beam scanning coefficient is 8 (scanning in 8 directions), 8 SSBs are required to complete the cell search. Therefore, the time required for SCell activation in FR2 is also longer than that in FR1.

[0081] SCell activation in FR2 is divided into known activation and unknown activation. In known activation, the base station already has measurement information for the SCell to be activated, which can be used to activate the cell. In unknown activation, the base station does not have measurement information for the SCell to be activated and cannot determine which measurement information to use to activate the SCell. To clarify which measurement information the base station should use to activate the SCell in unknown activation, when the UE receives the activation command, it can send previous measurement information to the base station. After receiving the measurement information, the base station can use it to activate the SCell.

[0082] When multiple SCells are activated simultaneously, the UE measures each SCell in turn, resulting in measurement information for multiple component carriers (CCs) generated at different times. As shown in Figure 1, CC1-CC4 are four carriers in the same FR2 band, and the base station configures the UE to measure on all four carriers. The UE needs to measure CC1-CC4 sequentially in chronological order, so measurement information for the best beams of CC1-CC4 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 UE mobility or channel variations, the SSB indices of CC1-CC4 obtained at different times may vary. Upon receiving the activation command, the UE reports measurement information for 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.

[0083] In the example shown in Figure 1, CC4's measurement information SSB#3 is the latest measurement information before activation, and activating the SCell based on this measurement information provides better performance. However, the base station cannot determine the order of the received SCell measurement information, and cannot determine which is the latest measurement information. If the base station configures TCI based on older measurement information (for example, measurement information from CC1-CC3), activation failure or performance loss may occur, affecting carrier performance after activation.

[0084] 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 SCell activation failure.

[0085] 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.

[0086] The communication method provided in the embodiments of the present application can be applied to various communication systems, such as: long term evolution (LTE) systems, fifth generation (5G) mobile communication systems, wireless fidelity (WiFi) systems, future communication systems, or systems integrating multiple communication systems, etc., and the embodiments of the present application are not limited thereto. 5G can also be referred to as new radio (NR).

[0088] The communication method provided in the embodiment of the present application is described below using the communication system shown in FIG2 as an example.

[0089] FIG2 is a schematic diagram of a communication system provided in an embodiment of the present application. As shown in FIG2 , the communication system may include:

[0090] Communication connection between network equipment and terminal equipment. Network equipment can cover one primary cell and multiple secondary cells. For example, network equipment covers a primary cell PCell and multiple secondary cells: SCell1, SCell2, and SCell3. In carrier aggregation, the primary cell PCell is responsible for security, switching, uplink physical control channel carrying, etc. 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 the SCell to the network device, so that the network device can activate the SCell based on the measurement information. After the SCell is activated, the network device and the terminal device can send and receive data based on the SCell.

[0091] It should be noted that Figure 2 is only an exemplary framework diagram, and the number of cells and the state of the terminal devices shown in Figure 2 are not limited. In addition to the functional nodes shown in Figure 2, other nodes may also be included, such as core network devices, gateway devices, application servers, etc., without limitation. Network devices communicate with core network devices via wired or wireless means, such as via next-generation (NG) interfaces.

[0092] 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 any one of a base station, a wireless access point, a transmission receive point (TRP), a transmission point (TP), and some other access nodes. 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.

[0093] 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, and may also be a virtual reality (VR) terminal device, an augmented reality (AR) terminal device, a wireless terminal device in industrial control, a wireless terminal device in unmanned driving, a wireless terminal device in telemedicine, a wireless terminal device in a smart grid, a wireless terminal device in a smart city, a smart home, or an in-vehicle terminal device, etc. In the embodiment of the present application, the device for realizing the function of the terminal device may be the terminal device, or may be a device that can support 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.

[0094] 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.

[0095] FIG3 shows a flow chart of a communication method provided by an embodiment of the present application. As shown in FIG3 , the method may include the following steps:

[0096] S310, the network device sends first information to the terminal device, and correspondingly, the terminal device receives the first information from the network device.

[0097] With reference to the introduction to the communication system in this application, a network device is communicatively connected to a terminal device, and data transmission, such as first information, can be performed between the two. The first information is used to indicate a secondary cell that needs to be activated. Specifically, the first information may indicate activation of one secondary cell, or the first information may indicate activation of multiple secondary cells. Exemplarily, the first information may be media access control (MAC) information.

[0098] S320, the terminal device sends second information to the network device, and correspondingly, the network device receives the second information from the terminal device.

[0099] The second information includes multiple sets of measurement information for multiple secondary cells with the same frequency band (or frequency range) as the secondary cell indicated in the first information, and indication information, where the indication information is used to indicate target measurement information in the multiple sets of measurement information. Exemplarily, the indication information may be carried in measurement identifier measID signaling. In another example, the indication information may also be carried in new signaling, without limitation.

[0100] Each set of measurement information includes information such as reference signal indication information (SSB index) and / or reference signal receiving power (RSRP). The SSB index can be used to configure TCI to activate the 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 indexes to activate the secondary cell.

[0101] The target measurement information is a set of measurement information that can successfully activate the secondary cell among multiple sets of measurement information. Taking into account 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.

[0102] In another example, the target measurement information can also be set to any set of measurement information in multiple sets of measurement information whose measurement time difference compared to the current time is less than a time threshold. The time threshold can be set flexibly and is not restricted. 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 multiple sets of measurement information, its measurement time is close to the current time. The activation performance of the secondary cell is usually better when it is activated based on this measurement information.

[0103] 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, and SCell3 and SCell4 are in the same frequency band band2, and the first information indicates the activation of SCell1. The second information includes multiple groups of measurement information and indication information of multiple secondary cells with the same secondary cell frequency band as the first information indicates. The second information includes the 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] Alternatively, the second information includes multiple sets of measurement information and indication information for multiple secondary cells in the same 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, where SCell1 and SCell2 are both in FR1, and 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 set of measurement information in the measurement information of SCell1 and SCell2, i.e., the target measurement information.

[0105] S330: The network device activates the secondary cell indicated by the first information according to the target measurement information.

[0106] 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: configuring 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); triggering the physical downlink control channel command random access (PDCCH order RACH) based on the SSB index in the target measurement information; configuring the uplink spatial relation (UL spatial relation) based on the SSB index in the target measurement information.

[0107] For example, assuming that the network device receives the second information including four sets of measurement information and indication information, where the SSB indexes in the four sets of measurement information are SSB#1, SSB#1, SSB#2, and SSB#3, respectively, and the indication information indicates that SSB#3 is the target measurement information, the network device activates the secondary cell indicated by the first information according to SSB#3. That is, the network device configures information such as the secondary cell TCI according to SSB#3.

[0108] In an embodiment of the present application, while the terminal device sends multiple sets 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 sets 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.

[0109] In one embodiment, the first information indicates activation of multiple secondary cells (the multiple secondary cells have different frequency bands or frequency ranges). In this embodiment, the activation of multiple secondary cells is described using the example of the first information indicating activation of two secondary cells (a first secondary cell and a second secondary cell). It should be understood that in a specific implementation, the first information may also indicate activation of three or more secondary cells. The activation process can refer to the activation process of two secondary cells and is not further described.

[0110] 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 (for activating the first secondary cell) and the target measurement information in the second measurement information group (for activating the second secondary cell).

[0111] 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 are in FR1), SCell3 and SCell4 are in the same frequency band band2 (or both are in FR2), and the first information indicates the 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.

[0112] 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.

[0113] In one embodiment, the first information indicates activation of multiple secondary cells (the multiple secondary cells have the same frequency band or the same frequency range). Since the multiple secondary cells have the same frequency band (or the same frequency range), 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 the other secondary cells indicated for activation. Accordingly, the multiple sets of measurement information for each secondary cell indicated for activation are the same. Therefore, the same target measurement information can be used to activate the multiple secondary cells indicated for activation. The specific activation process can be referred to the description of S310-S330 and will not be repeated here.

[0114] In one embodiment, when configuring a measurement object (MO), the terminal device is limited to configuring one MO for one band.

[0115] 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. The network device may select the group of measurement information with the latest measurement timestamp to activate the secondary cell.

[0116] The present application also provides a flow chart of another communication method, which is shown in Figure 4. As shown in Figure 4, the method may include the following steps:

[0117] S410, the network device sends first information to the terminal device, and correspondingly, the terminal device receives the first information from the network device.

[0118] 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.

[0119] 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.

[0120] The target measurement information is determined from multiple sets of measurement information for multiple secondary cells that share the same frequency band as the secondary cell indicated by the first information. The target measurement information is used to activate the secondary cell indicated by the first information. If the first information indicates activation of a single secondary cell, the target measurement information is a set. If the first information indicates activation of multiple secondary cells, and the multiple secondary cells indicated for activation are in the same frequency band (or in the same frequency range), then for each secondary cell indicated for activation, the multiple secondary cells that share the same frequency band as the secondary cell indicated for activation are consistent with the multiple secondary cells that share the same frequency band as the other secondary cells indicated for activation. Accordingly, the multiple sets of measurement information for each secondary cell indicated for activation are the same. Therefore, the same set of target measurement information can be used to activate the multiple secondary cells indicated for activation. In this case, the target measurement information is still a set. If the first information indicates activation of multiple secondary cells, and at least two of the multiple secondary cells indicated for activation are in different frequency bands (or in different frequency ranges), then the multiple frequency bands (or frequency ranges) of the multiple secondary cells indicated for activation are determined by the number of sets of target measurement information.

[0121] For example, in a certain communication scenario, the network device covers four secondary cells: SCell1, SCell2, SCell3, and SCell4, where 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 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, the two activated secondary cells are indicated to be in two frequency bands (or two frequency ranges), and there are two sets of target measurement information.

[0122] S430: The network device activates the secondary cell indicated by the first information according to the target measurement information.

[0123] 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.

[0124] In the embodiment of the present application, the terminal device sends target measurement information to the network device, and the network device can directly use the target measurement information to activate the secondary cell, thereby ensuring the activation performance of the secondary cell.

[0125] In one embodiment, the target measurement information is set to the latest set of measurement information among the multiple sets of measurement information.

[0126] Considering that the later the measurement information is measured, the more it matches the current communication state of the secondary cell, the better the performance of activating the secondary cell based on this measurement information. Therefore, for example, the target measurement information is set to the latest measurement information among the multiple sets of measurement information, and activating the secondary cell based on this measurement information results in better performance.

[0127] 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 is less than a preset time threshold among the multiple sets of measurement information.

[0128] The time threshold can be flexibly set without restriction. For example, the time threshold can be set to 5 ms. Although the target measurement information selected in this manner may not be the latest measurement information among the multiple measurement information sets, its measurement time is closer to the current time. Activating the secondary cell based on this measurement information generally results in better activation performance.

[0129] In an embodiment, the target measurement information may also be set as a combination of the first measurement information and the second measurement information.

[0130] Among them, the first measurement information is the latest measured among the 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 the SSB index 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 since the SSB index is the latest measured, the performance of activating the secondary cell is better.

[0131] Exemplarily, 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. Among them, the measurement information of SCell 1 is measured latest, so the first measurement information is the measurement information of SCell 1: SSB#1, RSRP 100. The SSB index of SCell 2 and SCell 4 is the same as that of SCell 1, both are SSB#1, so the second measurement information can be the measurement information of SCell 2 or the measurement information of SCell 4. The second measurement information can also be the measurement information of SCell 2 and the measurement information of SCell 4.

[0132] In another example, multiple sets 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. Among them, the measurement information of SCell 1 is measured latest, so the first measurement information is the measurement information of SCell 1: SSB#1,2,3, RSRP 100, and the SSB index of SCell 2 and SCell 4 is the same as that of SCell 1 (the same here does not require the SSB index to be completely consistent, as long as the other SSB index can be used as a subset of the SSB index in the first measurement information, it is considered 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 SCell 1. 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.

[0133] In an embodiment, the target measurement information may also be set as a combination of the first measurement information and the third measurement information.

[0134] The first measurement information is the latest measured value among the multiple sets of measurement information, and the third measurement information is partial measurement information of at least one set of measurement information among the multiple sets of measurement information, where the partial measurement information includes measurement information other than reference signal indication information. In this embodiment, although the target measurement information includes multiple sets of measurement information, the multiple sets of measurement information include a unique SSB index (i.e., the SSB index in the first measurement information). Upon receiving the target measurement information, the base station applies the SSB indicated by the unique SSB index to activate the secondary cell. Moreover, since the SSB index is the latest measured value, the performance of the activated secondary cell is better.

[0135] Exemplarily, the multiple sets 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. The measurement information of SCell 1 is measured last, so the first measurement information is the measurement information of SCell 1: SSB#1, RSRP 100. The third measurement information is the measurement information of at least one set of SCell 2, SCell 3, and SCell 4, excluding the SSB index.

[0136] The present application also provides a flow chart of another communication method. Unlike the communication methods shown in FIG3 or FIG4 , the communication method provided by this embodiment does not determine the target measurement information for activating the secondary cell by the terminal device, but rather determines the target measurement information by the network device. FIG5 shows a flow chart of this communication method. As shown in FIG5 , the method may include the following steps:

[0137] S510, the network device sends first information to the terminal device; correspondingly, the terminal device receives the first information,

[0138] 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.

[0139] S520, the terminal device sends multiple sets of measurement information to the network device; correspondingly, the network device receives the multiple sets of measurement information.

[0140] The multiple sets of measurement information are multiple sets of measurement information for 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 sets of measurement information include measurement information of SCell1 and SCell2.

[0141] S530: The network device determines target measurement information from multiple groups of measurement information.

[0142] Wherein, 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 repeated here. When the network device determines the target measurement information, the measurement information of the target secondary cell among the multiple secondary cells may be determined as the target measurement information.

[0143] In one embodiment, the target secondary cell is a secondary cell configured with a physical uplink control channel PUCCH (PUCCH SCell).

[0144] 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.

[0145] In one embodiment, the frequency of the target secondary cell is used to measure neighboring cells of the terminal device.

[0146] If multiple same-frequency measurements are configured within a single FR2 band, the terminal device is only required to measure both the neighboring cell and the secondary cell on one secondary carrier (SCC) (also known as a frequency point). For other secondary carriers (SCCs), only the secondary cell needs to be measured. The measurement period for the frequency point where both neighboring cells and secondary cells are measured is generally shorter. Therefore, the secondary cell measurement information measured on this frequency point is likely the latest measurement information. Activating the SCell based on the secondary cell measurement information measured on this frequency point provides better performance.

[0147] In one embodiment, the measurement cycle of the target secondary cell is the shortest among multiple measurement cycles of multiple secondary cells.

[0148] Among them, the network device includes configuring MeasCycleSCell when configuring the measurement of SCell. The terminal device will measure the SCell according to the configured MeasCycleSCell (for example, once every 160ms, once every 320ms, etc.). Therefore, the shorter the MeasCycleSCell, the shorter the SCell measurement period. The measurement information of the secondary cell configured with the shortest MeasCycleSCell is most likely measured last. In this case, the secondary cell configured with the shortest MeasCycleSCell is the target secondary cell.

[0149] In addition to MeasCycleSCell, the measurement cycle of the secondary cell may also be affected by other factors. The factors that affect the measurement cycle are shown in Table 1.

[0150] Table 1

[0151] The formula for determining the measurement period varies depending on the discontinuous reception cycle configuration. For details, 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. Smaller values ​​for CSSFintra, DRX cycle, and Mmeas_period_w / o_gaps indicate a shorter SCell measurement period. The secondary cell configured with the smallest parameter product is likely to be the last measured. In this case, the secondary cell configured with the smallest parameter product is designated as 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 may activate the secondary cell indicated by the first information according to the target measurement information. Specifically, the network device may configure the TCI using the SSB indicated by the SSB index in the target measurement information to activate the secondary cell.

[0155] In the embodiment of the present application, by configuring a rule for determining target measurement information on 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 solution 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 the execution of each function in order to implement the above functions.
