Alternatively, the communication system in embodiments of the present application can also be applied to licensed spectrum, which can also be considered as non-shared spectrum.

[0045] The communication system scenario includes a non-terrestrial network (NTN) system and a terrestrial network (TN) system. The NTN generally adopts a satellite communication mode to provide communication services to ground users. The NTN system currently includes an NR-NTN and an IoT-NTN system, and other NTN systems can be included in the future.

[0046] For example, FIG. 1 is a schematic diagram of an architecture of a communication system according to an embodiment of the present application.

For convenience of description, the above-mentioned devices are collectively referred to as terminal devices. In the embodiments of the present application, "terminal device" and "UE" are often used interchangeably, but those skilled in the art can understand that the two can express the same meaning.

[0052] The network device mentioned in the embodiments of the present application can be an access network device, which can be located on the ground or on a satellite. The access network device is a device deployed in the access network to provide wireless communication functions for terminal devices. The access network device can include various forms of macro base stations, micro base stations, relay stations, access points, etc. In systems using different wireless access technologies, the names of devices with access network device functions may vary, for example, in a 5G NR system, it is called gNodeB or gNB.

The small cell can include a metro cell, a micro cell, a pico cell, a femto cell, and the like. The small cell has the characteristics of small coverage and low transmit power, and is suitable for providing high-speed data transmission services.

[0055] Before introducing the technical solutions of the present application, some related technical knowledge involved in the present application will be introduced and explained. The following related technologies can be combined with the technical solutions of the embodiments of the present application in any way as optional solutions, which all belong to the protection scope of the embodiments of the present application. The embodiments of the present application include at least part of the following contents.

[0056] 1. Network energy saving

[0057] Network energy saving is of great significance to environmental sustainability, reducing the impact on the environment (reducing greenhouse gas emissions), and saving operating costs. With the gradual popularization of 5G in various industries and geographical areas, it is necessary to support very high data transmission rates to handle more advanced services and applications (such as XR), and the network deployment becomes denser, uses more antennas, has larger bandwidth, and uses more frequency bands. Considering the environmental impact of 5G, new solutions need to be developed to enhance network energy saving.

[0058] Energy consumption has become a key part of the operational expenditure (OPEX) of operators. According to the report of the Global System Mobile Association (GSMA), the energy cost of mobile networks accounts for about 23% of the total operational cost. Most of the energy consumption comes from the radio access network, more specifically, from the Active Antenna Unit (AAU), and the data center and fiber transmission account for a smaller share. The power consumption of a radio access can be divided into two parts: the dynamic part only includes the power consumption when data is being transmitted or received; the static part includes the power consumption necessary for the operation of the radio access device at all times, including the power consumption when no data is being transmitted or received.

[0059] Therefore, based on the above purpose, it is necessary to study and develop network energy consumption models, KPIs (Key Performance Indicators), evaluation methods, etc. on the network equipment side to determine and study network energy saving technologies in the target deployment scenario. Among them, the power consumption model on the terminal equipment side that has been defined can be used as a reference. This research should focus on how to achieve more effective dynamic operation and / or semi-static operation, and consider one or more network energy saving technologies applied in the time domain, frequency domain, spatial domain and power domain, combined with potential terminal device feedback support, potential terminal device assistance information, and information exchange or coordination between network interfaces, etc. to achieve more fine-grained data transmission and / or reception adaptation.

[0060] It is worth noting that this research not only evaluates the potential network energy saving gain, but also needs to evaluate and balance the impact on network and user performance by observing KPIs such as spectral efficiency, capacity, UPT (User Perceived Throughput), latency, UE power consumption, complexity, handover performance, call drop rate, initial access performance, SLA (Service Level Agreement) security-related KPIs, etc. This research should avoid having a large impact on the above-mentioned KPIs.

[0061] 2. SSB transmission and multi-carrier scenarios in NR systems

[0062] In the NR system, the initial access procedure of a terminal device can be completed by detecting a synchronization signal block (SSB or SS / PBCH block) on a synchronization raster. In the initial access procedure, the terminal device attempts to search for an SSB through a predefined possible time-frequency location of the SSB, and obtains time and frequency synchronization, radio frame timing, and a cell ID through the detected SSB. After the terminal device accesses the network, the network device can configure multiple serving cells as secondary cells for the terminal device according to the capability of the terminal device, so as to improve the peak rate of data transmission of the terminal device. On the secondary cell configured for the terminal device by the network device, the network device can not transmit an SSB burst, or transmit an SSB burst with a long period, so as to save the power consumption of the network device. The network device can activate or deactivate the secondary cell configured for the terminal device through a MAC CE (Media Access Control Control Element) command. Multiple activated serving cells of the terminal device can perform data transmission in a carrier aggregation (CA) or dual connectivity (DC) manner.

[0063] 3. SSB-based secondary cell activation latency in NR system

[0064] In the NR system, assuming that a first cell is a deactivated secondary cell configured for a terminal device, the latency in which the terminal device should be able to activate the first cell is:

[0065] In the case of receiving a first cell activation command on a slot n, the terminal device should be able to transmit valid CSI (Channel State Information) reporting and be able to communicate on the first cell according to the activation command no later than a slot n+((T HARQ +T activation_time +T CSI_reporting ) / NR slot length). Wherein,

[0066] T HARQ (unit: ms): the total length of time including a PDSCH (Physical Downlink Shared Channel) carrying the first cell activation command and an ACK (Acknowledgement) corresponding to the feedback of the PDSCH.

[0067] T activation_time(ms): includes the activation latency of the first cell. Exemplarily, the first cell activation latency can include the time length sum of one or more of MAC CE processing, Radio Frequency (RF) warm-up margin, Automatic Gain Control (AGC) gain setting, cell search, time-frequency synchronization tracking, SSB processing margin (e.g. Margin for SSB in last part), etc. The first cell activation latency is different in different scenarios.

[0068] T CSI_reporting (ms): includes the time length sum of the uncertainty time for acquiring the first available downlink CSI reference resource, the terminal (or UE) processing time for CSI reporting, and the uncertainty time for acquiring the first available CSI reporting resource.

[0069] NR slot length represents the length of a slot in a NR system determined according to a subcarrier spacing. For example, when the subcarrier spacing is 15 kHz, the NR slot length is 1 ms; when the subcarrier spacing is 30 kHz, the NR slot length is 0.5 ms; and when the subcarrier spacing is 60 kHz, the NR slot length is 0.25 ms.

[0070] The following takes FR1 (Frequency Range 1) as an example to describe the factors affecting the activation latency (T activation_time ) of the first cell. In combination with FIG. 4 and Table 1, T activation_time includes one or more of B, C, D, E, F, and G.

[0071] B+C: the time length of MAC CE processing and the time length of RF warm-up margin. In general, the time sum of B and C is 3 ms. It is worth noting that this part of processing time is irrelevant to SSB.

[0072] D: the time length of AGC gain setting. Exemplarily, if the first cell is a known cell and the first cell measurement period is less than or equal to 160 ms, D is 0, i.e. no AGC gain setting is needed. If the first cell is a known cell but the first cell measurement period is greater than 160 ms, D is T FirstSSB_MAX . If the first cell is an unknown cell, D is T FirstSSB_MAX +T SMTC_MAX .

[0073] E: the time length of cell search. Exemplarily, if the first cell is a known cell, E is 0, i.e. no cell search is needed. If the first cell is an unknown cell, E is T rs .

[0074] F: the length of time-frequency synchronization tracking. Exemplarily, if the first cell is a known cell, and the first cell measurement period is less than or equal to 160 ms, F takes the value of T FirstSSB If the first cell is a known cell, but the first cell measurement period is greater than 160 ms, or the first cell is an unknown cell, F takes the value of T rs .

[0075] G: the length of SSB processing margin. Typically, the time length of G is 2 ms.

[0076] Table 1

[0077] T SMTC_MAX : in FR1, T SMTC_MAX is the longer SMTC (SSB-based RRM Measurement Timing Configuration) period among the activated serving cell, the activated serving cell providing common reference signal for the activated secondary cell, and the secondary cell being activated or released in the same time slot; or, T SMTC_MAX is the SMTC period of the activated secondary cell; or, T SMTC_MAX is the SSB period of the activated secondary cell. In FR2 (Frequency Range 2), T SMTC_MAX is the longer SMTC period among the activated serving cell, and the activated secondary cell supporting FR2 intra-band CA only in R15; or, T SMTC_MAX is the SMTC period of the activated secondary cell; or, T SMTC_MAX is the SSB period of the activated secondary cell. Wherein, the minimum value of T SMTC_MAX is 10 ms.

[0078] T rs : T rs is the SMTC period of the activated secondary cell; or, T rs is the SMTC period corresponding to the same SSB frequency point and SSB SCS (Subcarrier Spacing) configured in RRM (Radio Resource Management) measurement (if the SMTC periods configured by the MN (Master Node) and the SN (Secondary Node) are different, the terminal device implementation determines which SMTC period to use); or, T rsSSB period of the secondary cell being activated.

[0079] T FirstSSB : the length of time from slot n + ((T HARQ + 3ms) / NR slot length) to the end of the first complete SSB burst indicated by SMTC, or within 5ms if SMTC is not configured.

[0080] T FirstSSB_MAX : the length of time from slot n + ((T HARQ + 3ms) / NR slot length) to the end of the first complete SSB burst indicated by SMTC, or within 5ms if SMTC is not configured, and further satisfying:

[0081] In FR1, when all active serving cells and the secondary cell being activated or released have the opportunity to transmit SSB bursts on the same slot; or, when the first opportunity for the secondary cell being activated to transmit SSB bursts;

[0082] In FR2, when all active serving cells and the secondary cell being activated or released have the opportunity to transmit SSB bursts on the same slot.

[0083] The terminal device can complete one or more of the foregoing D, E, F, G, L according to the SSB in the SMTC window or according to the SSB in the SSB period.

[0084] 4. On-demand SSB (OD-SSB) transmission on the secondary cell

[0085] As mentioned earlier, the network device can not transmit SSB bursts or transmit SSB bursts with a long period on the secondary cell configured for the terminal device. In order to realize the fast secondary cell activation of the terminal device, the network device can transmit an on-demand SSB burst (OD-SSB burst), as shown in FIG. 5. The OD-SSB indication information triggering the OD-SSB burst transmission can be sent at the time of secondary cell configuration (T1), can be sent when the secondary cell activation command is received (T2), or can be sent at a time between T1 and T2. In some cases, the OD-SSB indication information can also be sent after receiving the secondary cell activation command (after T2). For example, the network device sends the OD-SSB indication information at a time between T2 and T3.

[0086] In order to realize network energy saving, the network device can not transmit SSB on the secondary cell configured by the terminal device. Before the secondary cell configured by the terminal device is activated, or when the secondary cell configured by the terminal device is activated, the network device can send OD-SSB indication information to the terminal device through high-layer signaling (for example, MAC CE), and the OD-SSB indication information is used to trigger OD-SSB burst transmission on the secondary cell, for example, to indicate the transmission position of the OD-SSB burst on the secondary cell. The terminal device can realize the rapid activation of the secondary cell based on the OD-SSB burst. However, how the terminal device realizes the rapid activation of the secondary cell based on the OD-SSB burst still needs further research.

[0087] Please refer to FIG. 6, which shows a flowchart of a wireless communication method provided by an embodiment of the present application. The method can be applied to the network architecture shown in FIGS. 1 to 3. The method can include the following step 610.

[0088] In step 610, the terminal device receives first indication information, and the first indication information is used to determine the time domain position and / or the frequency domain position of a first SSB burst on a first cell, and the first cell is a deactivated secondary cell configured by the terminal device.

[0089] Before the secondary cell configured by the terminal device (that is, the above-mentioned first cell) is activated, the terminal device can receive the first indication information. The first indication information can also be referred to as OD-SSB indication information.

[0090] In some embodiments, the first indication information is used to determine at least one of the following: the time domain position of the first SSB burst on the first cell, the frequency domain position of the first SSB burst on the first cell, and whether the first SSB burst is transmitted on the first cell. The first SSB burst is the SSB burst determined according to the first indication information. The first SSB burst is the SSB burst on the first cell, for example, the first SSB burst is the OD-SSB burst on the first cell.

[0091] In some embodiments, the network device sends the first indication information, and accordingly, the terminal device receives the first indication information.

[0092] For the secondary cell of the terminal device, the first indication information can be used to trigger SSB burst transmission on the secondary cell, so that the terminal device can activate the secondary cell according to the SSB burst triggered by the first indication information, thereby realizing that on the secondary cell configured by the terminal device, the network device can not transmit SSB burst or transmit SSB burst with a long period to save the power consumption of the network device; when it is necessary to activate the secondary cell based on the SSB burst, the network device can trigger the SSB burst transmission to assist the terminal device to realize the rapid activation of the secondary cell.

[0093] In some embodiments, the first indication information is carried by one of the following: MAC CE signaling, RRC (Radio Resource Control) signaling, DCI (Downlink Control Information) signaling, and a system message block. Exemplarily, the first indication information is a MAC CE.

[0094] In some embodiments, the terminal device measures the first cell according to the first measurement manner or the second measurement manner. That is, the measurement manner in which the terminal device measures the first cell includes the following two: the first measurement manner and the second measurement manner.

[0095] In some embodiments, the first measurement manner includes that the time of starting to measure the first cell according to the first SSB burst is earlier than the first moment.

[0096] In some embodiments, the second measurement manner includes that the time of starting to measure the first cell according to the first SSB burst is not earlier than the first moment.

[0097] As can be seen from the above, the first measurement manner and the second measurement manner differ in the time of starting to measure the first cell, and the time of starting to measure the first cell according to the first measurement manner is earlier than the time of starting to measure the first cell according to the second measurement manner. Therefore, the first measurement manner can also be called an early measurement manner.

[0098] In some embodiments, the first moment is determined based on a PDSCH carrying the activation command information of the first cell, or the first moment is determined based on an uplink channel carrying HARQ-ACK (Hybrid Automatic Repeat reQuest-Acknowledgement) information. The HARQ-ACK information is the HARQ-ACK information corresponding to the PDSCH carrying the activation command information of the first cell. The PDSCH corresponding HARQ-ACK information refers to the HARQ feedback information for the PDSCH, which is used to indicate whether the PDSCH transmission is successful. In some embodiments, the HARQ-ACK information is ACK information corresponding to the PDSCH carrying the activation command information of the first cell. The PDSCH corresponding ACK information refers to the positive acknowledgment feedback information for the PDSCH, which is used to indicate that the PDSCH transmission is successful.

[0101] The starting time instant of the PDSCH carrying the activation command information of the first cell refers to a starting time domain position of a time domain resource occupied by the PDSCH, such as a starting time instant of a starting symbol of the PDSCH, i.e. a starting time instant of a first symbol in the time domain resource occupied by the PDSCH, or a starting time instant of a symbol with the earliest time domain position in the time domain resource occupied by the PDSCH.

[0102] The ending time instant of the PDSCH carrying the activation command information of the first cell refers to an ending time domain position of a time domain resource occupied by the PDSCH, such as an ending time instant of an ending symbol of the PDSCH, i.e. an ending time instant of a last symbol in the time domain resource occupied by the PDSCH, or an ending time instant of a symbol with the latest time domain position in the time domain resource occupied by the PDSCH.

[0103] In some embodiments, the time domain unit in which the PDSCH is located refers to a time slot in which the PDSCH is located.

[0104] The starting time instant of the time domain unit in which the PDSCH carrying the activation command information of the first cell is located refers to a starting time domain position of a time slot in which the PDSCH is located, such as a starting time instant of a starting symbol of the time slot in which the PDSCH is located, i.e. a starting time instant of a first symbol in the time slot in which the PDSCH is located, or a starting time instant of a symbol with the earliest time domain position in the time slot in which the PDSCH is located.

[0105] The ending moment of the time domain unit where the PDSCH carrying the activation command information of the first cell is located refers to the ending time domain position of the slot where the PDSCH is located, such as the ending moment of the ending symbol of the slot where the PDSCH is located, that is, the ending moment of the last symbol in the slot where the PDSCH is located, or the ending moment of the symbol with the latest time domain position in the slot where the PDSCH is located.

[0106] Of course, the above only takes the time domain unit as the slot as an example for introduction and description, and in other embodiments, the time domain unit can also be a subframe, a sub-slot, a frame, a half frame, etc., which is not limited in the application.

[0107] In some embodiments, the HARQ-ACK information is carried in an uplink channel, and exemplarily, the uplink channel can be a PUCCH (Physical Uplink Control Channel) or a PUSCH (Physical Uplink Shared Channel).

[0108] The starting moment of the uplink channel carrying the HARQ-ACK information refers to the starting time domain position of the time domain resource occupied by the uplink channel, such as the starting moment of the starting symbol of the uplink channel, that is, the starting moment of the first symbol in the time domain resource occupied by the uplink channel, or the starting moment of the symbol with the earliest time domain position in the time domain resource occupied by the uplink channel.

[0109] The ending moment of the uplink channel carrying the HARQ-ACK information refers to the ending time domain position of the time domain resource occupied by the uplink channel, such as the ending moment of the ending symbol of the uplink channel, that is, the ending moment of the last symbol in the time domain resource occupied by the uplink channel, or the ending moment of the symbol with the latest time domain position in the time domain resource occupied by the uplink channel. As shown in FIG. 4, the ending moment of the uplink channel carrying the HARQ-ACK information is the ending moment of T HARQ .

[0110] In some embodiments, the time domain unit where the uplink channel is located refers to the slot where the uplink channel is located.

[0111] The starting moment of the time domain unit where the uplink channel carrying the HARQ-ACK information is located refers to the starting time domain position of the slot where the uplink channel is located, such as the starting moment of the starting symbol of the slot where the uplink channel is located, that is, the starting moment of the first symbol in the slot where the uplink channel is located, or the starting moment of the symbol with the earliest time domain position in the slot where the uplink channel is located.

[0112] The ending moment of the time domain unit where the uplink channel carrying the HARQ-ACK information is located refers to the ending time domain position of the time slot where the uplink channel is located, such as the ending moment of the ending symbol of the time slot where the uplink channel is located, i.e., the ending moment of the last symbol in the time slot where the uplink channel is located, or the ending moment of the symbol with the latest time domain position in the time slot where the uplink channel is located.

[0113] In some embodiments, the first moment can also be a moment after the ending moment of the PDSCH carrying the activation command information of the first cell plus the first time length. That is, the first moment is later than the ending moment of the PDSCH carrying the activation command information of the first cell, and the first moment is later than the ending moment by the first time length, the starting moment of the first time length is the ending moment, and the length or value of the first time length is preset or determined according to the configuration information of the network device.

[0114] In some embodiments, the first moment can also be a moment after the ending moment of the uplink channel carrying the HARQ-ACK information plus the first time length; or the first moment is the effective moment of the activation command information of the first cell. That is, the first moment is later than the ending moment of the uplink channel carrying the HARQ-ACK information, and the first moment is later than the ending moment by the first time length, the starting moment of the first time length is the ending moment, and the length or value of the first time length is preset or determined according to the configuration information of the network device. As shown in FIG. 4, when the first moment is a moment after the ending moment of the uplink channel carrying the HARQ-ACK information plus the first time length, the first moment is the ending moment of C in FIG. 4.

[0115] In some embodiments, the first time length is a time length related to the activation command information of the first cell. For example, the first time length is the effective time length of the activation command information of the first cell. Exemplarily, the first time length is 3 ms (milliseconds).

[0116] It should be understood that when the ending moment of the PDSCH or the uplink channel is added to the first time length, the units of the two need to be converted to the same order of magnitude for calculation, such as conversion to the time slot or symbol level for calculation.

[0117] In some embodiments, the first time point is a starting time point of the PDSCH carrying the activation command information of the first cell; or, the first time point is a starting time point of a time domain unit in which the PDSCH carrying the activation command information of the first cell is located; or, the first time point is an ending time point of the PDSCH carrying the activation command information of the first cell; or, the first time point is an ending time point of a time domain unit in which the PDSCH carrying the activation command information of the first cell is located; or, the first time point is a time point after an ending time point of the PDSCH carrying the activation command information of the first cell plus a first time length. As an example, the first time point is a starting time point of PDSCH transmission, as shown in FIG. 4, that is, the first time point is a starting time point of T HARQ in FIG. 4.

[0118] That is, the first measurement manner can be understood as measuring before receiving the activation command information of the first cell, or in other words, the terminal device measures based on the first indication information. The second measurement manner can be understood as measuring after receiving the activation command information of the first cell.

[0119] In some embodiments, the first time point is a starting time point of the uplink channel carrying the HARQ-ACK information; or, the first time point is a starting time point of a time domain unit in which the uplink channel carrying the HARQ-ACK information is located; or, the first time point is an ending time point of the uplink channel carrying the HARQ-ACK information; or, the first time point is an ending time point of a time domain unit in which the uplink channel carrying the HARQ-ACK information is located. The HARQ-ACK information is the HARQ-ACK corresponding to the PDSCH carrying the activation command information of the first cell. As an example, as shown in FIG. 4, the first time point is an ending time point of the uplink channel carrying the HARQ-ACK information, that is, an ending time point of C in FIG. 4. HARQ in FIG. 4.

[0120] That is, the first measurement manner can be understood as measuring before feeding back the HARQ-ACK information corresponding to the activation command of the first cell, or in other words, the terminal device measures based on the first indication information. The second measurement manner can be understood as measuring after feeding back the HARQ-ACK information corresponding to the activation command of the first cell.

[0121] In some embodiments, the first time point is a time point after an ending time point of the uplink channel carrying the HARQ-ACK information plus a first time length. Or, the first time point is a time point of taking effect of the activation command information of the first cell. As an example, as shown in FIG. 4, a time point after an ending time point of the uplink channel carrying the HARQ-ACK information plus a first time length, that is, an ending time point of C in FIG. 4, wherein the first time length is 3 ms (a sum of lengths of B and C).

[0122] That is, the effective time of the MAC CE carrying the activation command information of the first cell is the time after the end time of the uplink channel carrying the HARQ-ACK information plus 3 ms (the first time length). The first measurement mode can be understood as measuring before the activation command of the first cell takes effect, or in other words, the terminal device measures based on the first indication information. The second measurement mode can be understood as measuring after the activation command of the first cell takes effect.

[0123] For the first measurement mode, as shown in FIG. 7, after determining the first SSB burst on the first cell, the terminal device measures the first cell based on the first SSB burst, such as layer 1 and / or layer 3 measurement. In this case, it is possible that the terminal device has measured the first cell, but the network device has not activated the first cell for the terminal device, thereby causing meaningless power consumption of the terminal device. In addition, for the unactivated secondary cell, the terminal device only needs to perform layer 3 measurement according to the configured SMTC window. If the terminal device is required to perform layer 1 and / or layer 3 measurement on the first cell according to the SSB period before receiving the activation command information of the first cell, additional terminal device processing complexity will also be brought.

[0124] For the second measurement mode, as shown in FIG. 8, even if the first SSB burst on the first cell is determined before receiving the activation command information of the first cell, the terminal device still measures the first cell based on the first SSB burst after receiving the activation command information of the first cell, such as layer 1 and / or layer 3 measurement. In this case, the delay of the secondary cell fast activation is not reduced.

[0125] The first measurement mode and the second measurement mode have their own advantages. The first measurement mode has a smaller activation delay for the secondary cell, but can bring additional power consumption and processing complexity. The second measurement mode has a larger activation delay for the secondary cell, but does not bring additional power consumption and processing complexity. Therefore, the terminal device needs to reasonably select the first measurement mode or the second measurement mode to meet the actual needs.

[0126] In some embodiments, the terminal device determines the measurement mode of the terminal device for the first cell based on the second indication information. The measurement mode includes the first measurement mode and / or the second measurement mode. The second indication information can be sent by the network device. For details of the first measurement mode and the second measurement mode, please refer to the above description, which will not be repeated here.

[0127] In some embodiments, as shown in FIG. 9, the method provided by the embodiments of the present application includes at least one of the following steps 620 and 630.

[0128] Step 620, the terminal device receives the second indication information.

[0129] At step 630, the terminal device determines a measurement manner of the terminal device to the first cell based on the second indication information.

[0130] In some embodiments, the second indication information is used to indicate the first measurement manner. In some embodiments, the measurement manner is the first measurement manner in a case that the terminal device receives the second indication information, and the measurement manner is the second measurement manner in a case that the terminal device does not receive the second indication information. For example, the terminal device determines the measurement manner of the first cell as the first measurement manner when the network device sends the second indication information, and determines the measurement manner of the first cell as the second measurement manner when the network device does not send the second indication information.

[0131] In some embodiments, the second indication information is used to indicate the second measurement manner. In some embodiments, the measurement manner is the second measurement manner in a case that the terminal device receives the second indication information, and the measurement manner is the first measurement manner in a case that the terminal device does not receive the second indication information. For example, the terminal device determines the measurement manner of the first cell as the second measurement manner when the network device sends the second indication information, and determines the measurement manner of the first cell as the first measurement manner when the network device does not send the second indication information.

[0132] In some embodiments, the second indication information is used to indicate the first measurement manner or the second measurement manner. In some embodiments, the measurement manner is the first measurement manner in a case that the second indication information indicates a first value, and the measurement manner is the second measurement manner in a case that the second indication information indicates a second value; wherein the first value and the second value are different. For example, the second indication information includes 1 bit, the terminal device determines the measurement manner of the first cell as the first measurement manner when the bit is the first value, and determines the measurement manner of the first cell as the second measurement manner when the bit is the second value. For example, the first value is 1 and the second value is 0, or the first value is 0 and the second value is 1.

[0133] In some embodiments, the second indication information is associated with the first cell, or the second indication information is associated with a cell identifier (ID) of the first cell. For example, the network device configures the second indication information for the first cell, and the second indication information is used to determine the measurement manner of the first cell.

[0134] In some embodiments, the second indication information is associated with a first cell group, or the second indication information is associated with a cell group identifier of the first cell group, wherein the first cell is included in the first cell group. For example, the network device configures the second indication information for the first cell group, and the second indication information is used to determine the measurement manner of the first cell group. For example, the measurement manner of each cell belonging to the same cell group is the same.

[0135] In some embodiments, the second indication information is associated with the terminal device, or the second indication information is configured for the terminal device. For example, the network device configures the second indication information for the terminal device, and the second indication information is used to determine the measurement manner of the terminal device on the secondary cell corresponding to the first indication information. Illustratively, the terminal device is configured to trigger the SSB burst on multiple secondary cells corresponding to the first indication information, and the measurement manner of the terminal device on the multiple secondary cells is determined according to the second indication information.

[0136] In some embodiments, the first indication information is used to determine the first SSB burst, and the terminal device performs measurement based on the later time between the start time of the first SSB burst and the time when the terminal device receives the second indication information. Illustratively, if the start time of the first SSB burst is later than the time when the terminal device receives the second indication information, the terminal device performs measurement based on the start time of the first SSB burst. Illustratively, if the time when the terminal device receives the second indication information is later than the start time of the first SSB burst, the terminal device performs measurement based on the second indication information.

[0137] In some embodiments, the first indication information is used to determine the first SSB burst, and the terminal device performs measurement based on the later time between the start time of the first SSB burst and the validity time of the second indication information. For example, when the second indication information is carried in a MAC CE, the validity time of the second indication information is the time after the end of the transmission of the uplink channel carrying the HARQ-ACK information corresponding to the second indication information plus 3ms. Illustratively, if the start time of the first SSB burst is later than the validity time of the second indication information, the terminal device performs measurement based on the start time of the first SSB burst. Illustratively, if the validity time of the second indication information is later than the start time of the first SSB burst, the terminal device performs measurement based on the validity time of the second indication information.

[0138] In some embodiments, the first indication information and the second indication information are carried in the same signaling. Illustratively, the first indication information and the second indication information are carried in the same high-layer signaling. The high-layer signaling can be a MAC CE or an RRC signaling. Taking the high-layer signaling as a MAC CE as an example, the first indication information and the second indication information are carried in the same MAC CE. Taking the high-layer signaling as an RRC signaling as an example, the first indication information and the second indication information are carried in the same RRC signaling.

[0139] In some embodiments, the first indication information and the second indication information are carried in different signaling. For example, the first indication information and the second indication information are carried in different MAC CEs. For another example, the first indication information and the second indication information are carried in different RRC signaling. For another example, the first indication information is carried in a MAC CE, and the second indication information is carried in RRC signaling. For another example, the first indication information is carried in RRC signaling, and the second indication information is carried in a MAC CE.

[0140] In some embodiments, the measurement manner for the first cell described above can also be understood as a measurement configuration for the first cell, i.e., a measurement manner for the first cell configured by the network device for the terminal device.

[0141] Through the above method, the network device can determine whether to require the terminal device to measure in advance based on its own scheduling decision. For example, when the network device sends the first indication information, if it has determined to send the activation command information of the first cell to the terminal device next, or has determined to send the activation command information of the first cell to the terminal device within a first time period after sending the first indication information, the network device can send the second indication information to the terminal device, which is used to indicate that the measurement manner of the terminal device for the first cell is the first measurement manner. Or, when the network device sends the first indication information, if it does not determine whether to send the activation command information of the first cell to the terminal device next, or has determined not to send the activation command information of the first cell to the terminal device within a first time period after sending the first indication information, the network device can send the second indication information to the terminal device, which is used to indicate that the measurement manner of the terminal device for the first cell is the second measurement manner. Through this method, the activation delay of the first cell can be reduced, and the meaningless power consumption of the terminal device can be avoided.

[0142] In some embodiments, in the case that the terminal device receives the second indication information, the terminal device receives the activation command information of the first cell. For example, the terminal device receives the activation command information of the first cell sent by the network device after receiving the second indication information or receiving the first indication information and the second indication information; or, the terminal device expects to receive the activation command information of the first cell sent by the network device after receiving the second indication information or receiving the first indication information and the second indication information; or, the terminal device does not expect to receive the activation command information of the first cell sent by the network device after receiving the second indication information or receiving the first indication information and the second indication information.

[0143] In some embodiments, the terminal device receives the activation command information of the first cell within the second time length in a case where the terminal device receives the second indication information. Illustratively, the terminal device receives the activation command information of the first cell sent by the network device within the second time length after receiving the second indication information or receiving the first indication information and the second indication information; or, the terminal device expects to receive the activation command information of the first cell sent by the network device within the second time length after receiving the second indication information or receiving the first indication information and the second indication information; or, the terminal device does not expect to receive the activation command information of the first cell sent by the network device within the second time length after receiving the second indication information or receiving the first indication information and the second indication information.

[0144] In some embodiments, the terminal device receives the activation command information of the first cell in a case where the terminal device determines that the measurement manner of the first cell is the first measurement manner based on the second indication information. Illustratively, the terminal device receives the activation command information of the first cell sent by the network device in a case where the terminal device determines that the measurement manner is the first measurement manner based on the second indication information after receiving the first indication information; or, the terminal device expects to receive the activation command information of the first cell sent by the network device in a case where the terminal device determines that the measurement manner is the first measurement manner based on the second indication information; or, the terminal device does not expect to receive the activation command information of the first cell sent by the network device in a case where the terminal device determines that the measurement manner is the first measurement manner based on the second indication information.

Illustratively, the terminal device receives the activation command information of the first cell sent by the network device within the second time length in a case where the terminal device determines that the measurement manner of the first cell is the first measurement manner based on the second indication information after receiving the first indication information; or, the terminal device expects to receive the activation command information of the first cell sent by the network device within the second time length in a case where the terminal device determines that the measurement manner of the first cell is the first measurement manner based on the second indication information; or, the terminal device does not expect to receive the activation command information of the first cell sent by the network device within the second time length in a case where the terminal device determines that the measurement manner of the first cell is the first measurement manner based on the second indication information.

[0146] In some embodiments, the length of the second time length is preset; or, the length of the second time length is determined based on the third indication information sent by the network device. Illustratively, the third indication information contains the length of the second time length.

[0147] In some embodiments, the starting point of the second time length is the second time point.

[0148] In some embodiments, the second time instance comprises one of: a validity time instance of the first indication information; a starting time instance of the first downlink channel carrying the first indication information; an ending time instance of the first downlink channel carrying the first indication information; a starting time instance of a time domain unit in which the first downlink channel carrying the first indication information is located; an ending time instance of the time domain unit in which the first downlink channel carrying the first indication information is located; a starting time instance of the first uplink channel; an ending time instance of the first uplink channel; a starting time instance of a time domain unit in which the first uplink channel is located; an ending time instance of the time domain unit in which the first uplink channel is located; a validity time instance of the second indication information; a starting time instance of the second downlink channel carrying the second indication information; an ending time instance of the second downlink channel carrying the second indication information; a starting time instance of a time domain unit in which the second downlink channel carrying the second indication information is located; an ending time instance of the time domain unit in which the second downlink channel carrying the second indication information is located; a starting time instance of the second uplink channel; an ending time instance of the second uplink channel; a starting time instance of a time domain unit in which the second uplink channel is located; an ending time instance of the time domain unit in which the second uplink channel is located.

[0149] In some embodiments, the validity time instance of the first indication information is one of: a time instance after an ending time instance of the first uplink channel by a first time duration; a starting position of the first SSB burst; a starting position of a first transmitted SSB in the first SSB burst; a starting position of a first SSB for measurement in the first SSB burst; a starting position of a first SSB burst corresponding to the first SSB burst after receiving the first indication information; a starting position of a first transmitted SSB in the first SSB burst corresponding to the first SSB burst after receiving the first indication information; a starting position of a first SSB for measurement in the first SSB burst corresponding to the first SSB burst after receiving the first indication information. The starting position can be understood as a starting symbol. Exemplarily, the first indication information is a MAC CE, and the validity time instance of the first indication information is a time instance after an ending time instance of the first uplink channel by a first time duration (e.g., 3 ms).

[0150] In some embodiments, the validity time instance of the second indication information is a time instance after an ending time instance of the second uplink channel by the first time duration. Exemplarily, the second indication information is a MAC CE, and the validity time instance of the second indication information is a time instance after an ending time instance of the second uplink channel by a first time duration (e.g., 3 ms).

[0151] In some embodiments, the first uplink channel is used to transmit HARQ-ACK information corresponding to the first downlink channel carrying the first indication information. The first downlink channel can be a PDSCH or a PDCCH (Physical Downlink Control Channel). The first uplink channel can be a PUCCH or a PUSCH.

[0152] In some embodiments, the second uplink channel is used to transmit HARQ-ACK information corresponding to the second downlink channel carrying the second indication information. The second downlink channel can be a PDSCH or a PDCCH. The second uplink channel can be a PUCCH or a PUSCH.

[0153] In some embodiments, the first downlink channel and the second downlink channel are the same downlink channel. The first uplink channel and the second uplink channel are the same uplink channel. Exemplarily, the first indication information and the second indication information are carried in the same signaling.

[0154] In addition, the explanations of the above-mentioned starting time, ending time, starting time of the time domain unit, and ending time of the time domain unit can be referred to the above, and will not be repeated here.

[0155] The technical solution provided by the embodiments of the present application can determine whether the terminal device needs to measure in advance based on the scheduling decision of the network device. Through this method, the activation delay of the secondary cell of the terminal device can be reduced, and meaningless power consumption of the terminal device can be avoided.

[0156] Next, the terminal device reports its measurement capability to the network device.

[0157] In some embodiments, the terminal device determines the measurement manner of the terminal device to the first cell based on the fourth indication information, and the measurement manner includes the first measurement manner and / or the second measurement manner. The fourth indication information is used to report the measurement capability of the terminal device. The first measurement manner and the second measurement manner are introduced and described above, and will not be repeated here.

[0158] In some embodiments, the fourth indication information is used to report that the terminal device supports the first measurement manner. In some embodiments, in the case that the terminal device sends the fourth indication information to the network device, the measurement manner of the terminal device to the first cell is the first measurement manner; in the case that the terminal device does not send the fourth indication information to the network device, the measurement manner of the terminal device to the first cell is the second measurement manner.

[0159] In some embodiments, the fourth indication information is used to report that the terminal device does not support the first measurement manner. In some embodiments, in the case that the terminal device sends the fourth indication information to the network device, the measurement manner of the terminal device to the first cell is the second measurement manner; in the case that the terminal device does not send the fourth indication information to the network device, the measurement manner of the terminal device to the first cell is the first measurement manner.

[0160] In some embodiments, the terminal device sends fourth indication information, and the fourth indication information is used to report the measurement capability of the terminal device. In this case, the fourth indication information is used to report that the terminal device supports the first measurement manner, or the fourth indication information is used to report that the terminal device does not support the first measurement manner. As described above, the terminal device needs additional processing complexity to measure the first cell based on the first measurement manner, and therefore should belong to the capability enhancement of the terminal device. The terminal device sends the fourth indication information to the network device, and reports the measurement capability of the terminal device through the fourth indication information. In some embodiments, in the case where the fourth indication information is used to report that the terminal device supports the first measurement manner, the measurement manner of the terminal device for the first cell is the first measurement manner; in the case where the fourth indication information is used to report that the terminal device does not support the first measurement manner, the measurement manner of the terminal device for the first cell is the second measurement manner.

[0161] In this way, the terminal device only needs to report the measurement capability of the terminal device to the network device, and the terminal device determines the measurement manner for the first cell based on the reported measurement capability, without the need for additional configuration of the network device.

[0162] In some embodiments, in the case where the terminal device sends the fourth indication information, the terminal device receives the second indication information. The network device can configure the measurement manner of the terminal device for the first cell based on the received fourth indication information, or the measurement capability of the terminal device determined based on the fourth indication information.

[0163] In some embodiments, in the case where the terminal device sends the fourth indication information, if the terminal device receives the second indication information sent by the network device, the terminal device determines the measurement manner indicated by the second indication information as the measurement manner for the first cell.

[0164] In some embodiments, in the case where the terminal device sends the fourth indication information, if the terminal device does not receive the second indication information sent by the network device, in the case where the terminal device supports the first measurement manner, the terminal device measures the first cell based on the first measurement manner; in the case where the terminal device does not support the first measurement manner, the terminal device measures the first cell based on the second measurement manner.

[0165] In some embodiments, in the case where the fourth indication information is used to report that the terminal device supports the first measurement manner, the terminal device receives the second indication information. Exemplarily, the second indication information can indicate the first measurement manner, or can indicate the second measurement manner.

[0166] In some embodiments, in the case that the terminal device sends the fourth indication information to the network device, and the fourth indication information is used to report that the terminal device supports the first measurement manner, if the terminal device receives the second indication information sent by the network device, the terminal device determines the measurement manner indicated by the second indication information as the measurement manner for the first cell.

[0167] In some embodiments, in the case that the terminal device sends the fourth indication information to the network device, and the fourth indication information is used to report that the terminal device supports the first measurement manner, if the terminal device does not receive the second indication information sent by the network device, the terminal device measures the first cell based on the first measurement manner. That is, if the second indication information is not received, the default measurement manner of the terminal device is the first measurement manner.

[0168] In some embodiments, in the case that the terminal device sends the fourth indication information to the network device, and the fourth indication information is used to report that the terminal device supports the first measurement manner, if the terminal device does not receive the second indication information sent by the network device, the terminal device measures the first cell based on the second measurement manner. That is, if the second indication information is not received, the default measurement manner of the terminal device is the second measurement manner.

[0169] In some embodiments, in the case that the terminal device sends the fourth indication information, the terminal device receives the activation command information of the first cell within the second time length, or the terminal device expects to receive the activation command information of the first cell within the second time length, or the terminal device does not expect to receive the activation command information of the first cell within the second time length.

[0170] In some embodiments, in the case that the fourth indication information is used to report that the terminal device supports the first measurement manner, the terminal device receives the activation command information of the first cell within the second time length, or the terminal device expects to receive the activation command information of the first cell within the second time length, or the terminal device does not expect to receive the activation command information of the first cell within the second time length.

[0171] Exemplarily, in the above embodiments, the start point of the second time length comprises one of: an effective time of the first indication information; a start time of the first downlink channel carrying the first indication information; an end time of the first downlink channel carrying the first indication information; a start time of a time domain unit in which the first downlink channel carrying the first indication information is located; an end time of the time domain unit in which the first downlink channel carrying the first indication information is located; a start time of the first uplink channel; an end time of the first uplink channel; a start time of a time domain unit in which the first uplink channel is located; and an end time of the time domain unit in which the first uplink channel is located. The effective time of the first indication information is one of: a time after the end time of the first uplink channel plus the first time length; a start position of the first SSB burst; a start position of a first transmitted SSB in the first SSB burst; a start position of a first SSB for measurement in the first SSB burst; a start position of a first SSB burst corresponding to the first SSB burst after receiving the first indication information; a start position of a first transmitted SSB in the first SSB burst corresponding to the first SSB burst after receiving the first indication information; and a start position of a first SSB for measurement in the first SSB burst corresponding to the first SSB burst after receiving the first indication information. The first uplink channel is used to transmit HARQ-ACK information corresponding to the first downlink channel carrying the first indication information. The first downlink channel can be a PDSCH or a PDCCH. The first uplink channel can be a PUCCH or a PUSCH.

[0172] In the above manner, the network device can determine the measurement manner of the secondary cell configured for the terminal device according to the measurement capability of the terminal device, so as to meet the capability of the terminal device.

[0173] Next, the activation delay of the first cell is introduced and described.

[0174] In some embodiments, the activation delay of the first cell comprises a time interval from when the terminal device receives the activation command information of the first cell to when the terminal device can communicate on the first cell. In some embodiments, the activation delay of the first cell comprises a time interval from the first time introduced above to when the first cell is activated.

[0175] In some embodiments, the activation delay of the first cell does not include the third time length and / or the fourth time length.

[0176] In some embodiments, in the case that the measurement manner of measuring the first cell comprises the first measurement manner introduced above, the activation delay of the first cell does not include the third time length and / or the fourth time length.

[0177] In some embodiments, the unit of the third time length is ms or the length of an NR slot.

[0178] In some embodiments, the fourth time length is in ms or NR slot length.

[0179] In some embodiments, the third time length is determined based on a time length of measurement of the first cell by the terminal device before receiving the activation command information of the first cell; or, the third time length is determined based on a time length of measurement of the first cell by the terminal device before the first time point. Illustratively, the third time length includes at least part of the time length of T activation_time . adv_act .

[0180] In the illustration of FIG. 4, the activation delay of the first cell is T HARQ + T activation_time + T CSI_reporting In the case where the activation delay of the first cell does not include the third time length, the activation delay of the first cell can be represented as T HARQ + T activation_time - T adv_act + T CSI_reporting .

[0181] Illustratively, the first cell is a deactivated secondary cell configured for the terminal device, and the time delay at which the terminal device should be able to activate the first cell is:

[0182] In the case where the activation command information of the first cell is received at slot n, the time at which the terminal device should be able to transmit valid CSI reporting and communicate on the first cell according to the activation command information is no later than slot n + ((T HARQ + T activation_time - T adv_act + T CSI_reporting ) / NR slot length.

[0183] In some embodiments, the third time length is determined based on at least one of the following time lengths of measurement of the first cell by the terminal device before receiving the activation command information of the first cell: time length of AGC gain setting, time length of cell search, time length of time-frequency synchronization tracking, time length of SSB processing margin.

[0184] In some embodiments, the third time length is determined based on at least one of the following time lengths of measurement of the first cell by the terminal device before the first time point: time length of AGC gain setting, time length of cell search, time length of time-frequency synchronization tracking, time length of SSB processing margin.

[0185] It can be understood that the MAC CE processing time and the time length of the RF preheating margin are operations that are performed after receiving the activation command information of the first cell, and therefore the third time length does not include the processing time of this part. That is, the third time length includes the sum of the time lengths of one or more of the time length of AGC gain setting, the time length of cell search, the time length of time-frequency synchronization tracking, and the time length of SSB processing margin.

[0186] Exemplarily, the first cell is a deactivated secondary cell configured for the terminal device, and if in the second measurement manner, the time delay in which the terminal device should be able to activate the first cell is determined according to the sum of the following time lengths: T HARQ (k1+A), the time length of MAC CE processing and RF preheating margin (B+C), the time length of AGC gain setting (D), the time length of cell search (E), the time length of time-frequency synchronization tracking (F), the time length of SSB processing margin (G), T CSI_reporting (L); then in the first measurement manner, assuming that the terminal device has completed the measurement of D, E, F and G on the first cell before the first time, the third time length is the sum of the time lengths of D, E, F and G; the time delay in which the terminal device should be able to activate the first cell is determined according to the sum of the following time lengths: T HARQ , B+C, L.

[0187] Exemplarily, the first cell is a deactivated secondary cell configured for the terminal device, and if in the second measurement manner, the time delay in which the terminal device should be able to activate the first cell is determined according to the sum of the following time lengths: T HARQ (k1+A), the time length of MAC CE processing and RF preheating margin (B+C), the time length of time-frequency synchronization tracking (F), the time length of SSB processing margin (G), T CSI_reporting (L); then in the first measurement manner, assuming that the terminal device has completed the measurement of F and G on the first cell before the first time, the third time length is the sum of the time lengths of F and G; the time delay in which the terminal device should be able to activate the first cell is determined according to the sum of the following time lengths: T HARQ , B+C, L.

[0188] In some embodiments, if the time length between the start time of T HARQ and the first time overlaps with the third time length, the activation time delay of the first cell is determined according to one of the following cases:

[0189] Case 1: The activation time delay of the first cell does not additionally consider the time length of the overlapping part between the time length between the start time of T HARQ and the first time and the third time length;

[0190] Case 2: The activation time delay of the first cell additionally considers the time length of the overlapping part between the time length between the start time of THARQ the duration between the starting moment of T

[0191] Exemplarily, the first moment is the ending moment of T HARQ the ending moment of T HARQ the duration between the starting moment of T HARQ the duration between the starting moment of T adv_act . The third duration is denoted as T HARQ the duration of T HARQ +T activation_time -T adv_act +T CSI_reporting . According to case 1, the activation delay of the first cell is T HARQ +T HARQ -T activation_time +T adv_act +deltaT, where deltaT represents the duration of the overlapping part of the third duration and the duration of T CSI_reporting ; or, if the third duration includes the duration of T HARQ in the time domain, the activation delay of the first cell is T HARQ +T HARQ -T activation_time +T adv_act +T CSI_reporting +T HARQ ; or, if the duration of T HARQ includes the third duration in the time domain, the activation delay of the first cell is T HARQ +T activation_time +T CSI_reporting .

[0192] Exemplarily, the first moment is the ending moment of T HARQ the duration between the starting moment of T HARQ the sum of the durations of T HARQ +3) milliseconds. The third duration is denoted as T adv_act . The duration of T HARQ +3 and the third duration at least partially overlap in the time domain. According to case 1, the activation delay of the first cell is T HARQ +T activation_time -T adv_act +T CSI_reporting . According to case 2, if the duration of T HARQ +3 and the third duration partially overlap in the time domain, the activation delay of the first cell is T HARQ +T activation_time -T adv_act +TCSI_reporting + deltaT, where deltaT represents the third time length and T HARQ + 3, or, if the third time length includes the time length of T HARQ + 3 in the time domain, the activation delay of the first cell is T HARQ + T activation_time - T adv_act + T CSI_reporting + T HARQ + 3, or, if the third time length includes the time length of T HARQ + 3 in the time domain, the activation delay of the first cell is T HARQ + T activation_time + T CSI_reporting .

[0193] In some embodiments, if the first cell is a known cell, the third time length includes the time length of time-frequency synchronization tracking and / or the time length of SSB processing margin.

[0194] In some embodiments, the start of the third time length is the second time. Illustratively, the second time is the effective time of the first indication information.

[0195] The following takes the start of the third time length as the effective time of the first indication information (OD-SSB indication information), and the first time is the end time of the uplink channel carrying the HARQ-ACK information (i.e., the end time of T HARQ , where the HARQ-ACK information is the ACK information corresponding to the PDSCH carrying the activation command information of the first cell. In this example, the terminal device is configured by the network device to measure in advance, i.e., using the first measurement method. Wherein, the items that the terminal device can measure in advance include one or more of AGC gain setting (D), cell search (E), time-frequency synchronization tracking (F), SSB processing margin (G).

[0196] Figure 10 shows an example of terminal device measurement in advance. As shown in Figure 10, the time interval between the effective time of the first indication information and the first time (the time of receiving the activation command information of the first cell (i.e., the secondary cell)) is greater than or equal to the sum of the processing time of the AGC gain setting (D), the cell search (E), the time-frequency synchronization tracking (F), and the SSB processing margin (G) that the terminal device needs to perform, so the third time length is T adv_act= D + E + F + G. It's understandable that if the terminal device doesn't need to perform a particular measurement, the third duration doesn't include the corresponding measurement duration. For example, if the terminal device doesn't need to perform cell search (e.g., the first cell is a known cell), the third duration doesn't include the duration corresponding to cell search (E). Accordingly, when the terminal device determines the activation delay of the first cell, it should subtract the third duration. That is, the activation delay of the first cell is determined by T. HARQ Duration, T activation_time The duration of MAC CE processing and RF warm-up margin (i.e., 3ms), and T CSI_reporting The duration is determined. Understandably, in the example of Figure 10, T... HARQ The durations of the first and third durations do not overlap in the time domain. In other words, in this case, the terminal device should be able to activate the first cell with the following latency:

[0197] Upon receiving the activation command information for the first cell in time slot n, the terminal device should be able to transmit a valid CSI report and communicate in the first cell no later than time slot n + ((T) HARQ +3+T CSI_reporting ( / NR time slot length).

[0198] If the third duration and T HARQ The durations overlap at least partially, and the terminal device determines the activation delay of the first cell to include one of the following:

[0199] Case 1: The activation latency of the first cell is T. HARQ +T activation_time -T adv_act +T CSI_reporting ;

[0200] Scenario 2: The activation latency of the first cell is T. HARQ +T activation_time -T adv_act +T CSI_reporting +deltaT, where deltaT represents the third duration and T. HARQ The duration of the overlapping portion.

[0201] FIG. 11 shows another example of the terminal device advanced measurement. As shown in FIG. 11, the time interval between the effective time of the first indication information and the first time (the time of receiving the first cell (i.e., the secondary cell) activation command information) is less than the sum of the processing time of the AGC gain setting (D) that the terminal device needs to perform, the cell search (E), the time-frequency synchronization tracking (F), and the SSB processing margin (G), and thus the length of the third time length is the time interval between the first time and the time of receiving the activation command information of the first cell. Accordingly, the terminal device determines that the length of the third time length should be subtracted from the activation delay of the first cell at the time. It can be understood that the length of the third time length in the example of FIG. 11 is greater than the T HARQ time length. It should be noted here that the third time length and the T HARQ time length at least partially overlap. The terminal device determines the activation delay of the first cell in one of the following cases:

[0202] Case 1: the activation delay of the first cell is T HARQ + T activation_time -T adv_act + T CSI_reporting ;

[0203] Case 2: in the case of T adv_act >T HARQ , the activation delay of the first cell is T HARQ + T activation_time -(T adv_act -T HARQ )+ T CSI_reporting ;

[0204] Case 3: in the case of T adv_act ≤ T HARQ , the activation delay of the first cell is T HARQ + T activation_time + T CSI_reporting .

[0205] In some embodiments, the fourth time length is determined based on the time length of the terminal device measuring and / or reporting the CSI of the first cell before receiving the activation command information of the first cell; the fourth time length is determined based on the time length of the terminal device measuring and / or reporting the CSI of the first cell before the first time. Exemplarily, the fourth time length includes at least part of the time length of T CSI_reporting introduced above. For example, the fourth time length is denoted as Tadvanced_CSI_reporting, which is abbreviated as T adv_CSI .

[0206] In some embodiments, the fourth time length is determined based on at least one of the following time lengths of the terminal device to the first cell before receiving the activation command information of the first cell: uncertainty time of acquiring the first available downlink CSI reference resource, terminal processing time of CSI reporting, and uncertainty time of acquiring the first available CSI reporting resource.

[0207] In some embodiments, the fourth time length is determined based on at least one of the following time lengths of the terminal device to the first cell before the first time: uncertainty time of acquiring the first available downlink CSI reference resource, terminal processing time of CSI reporting, and uncertainty time of acquiring the first available CSI reporting resource.

[0208] In the case shown in FIG. 4, the activation delay of the first cell is T HARQ +T activation_time +T CSI_reporting In the case where the activation delay of the first cell does not include the third time length and the fourth time length, the activation delay of the first cell can be represented as T HARQ +T activation_time -T adv_act +T CSI_reporting -T adv_CSI .

[0209] Exemplarily, the first cell is a deactivated secondary cell configured for the terminal device, and the time delay at which the terminal device should be able to activate the first cell is:

[0210] In the case where the terminal device receives the activation command information of the first cell at time slot n, the time at which the terminal device should be able to transmit valid CSI reporting and communicate on the first cell according to the activation command information is not later than time slot n+((T HARQ +T activation_time -T adv_act +T CSI_reporting -T adv_CSI ) / NR time slot length).

[0211] Exemplarily, the first cell is a deactivated secondary cell configured for the terminal device, and if in the second measurement mode, as shown in FIG. 4, the time delay at which the terminal device should be able to activate the first cell is determined according to the sum of the following time lengths: T HARQ (k1+A), the time length of RF preheating margin (B+C), the time length of AGC gain setting (D), the time length of cell search (E), the time length of time-frequency synchronization tracking (F), the time length of SSB processing margin (G), T CSI_reporting(L); then in the first measurement mode, assuming that the terminal device has completed the measurement and / or reported D, E, F, G and L of the first cell before the first time point, the third time length is the sum of the time lengths of D, E, F and G, and the fourth time length is the sum of the time length of L; the time delay in which the terminal device should be able to activate the first cell is determined according to the sum of the following time lengths: T HARQ , B + C.

[0212] In some embodiments, if the time length between the start time point of T HARQ and the first time point overlaps with the fourth time length, the activation time delay of the first cell is determined according to one of the following cases:

[0213] Case 1: The activation time delay of the first cell does not additionally consider the time length of the overlapping part between the time length between the start time point of T HARQ and the first time point and the fourth time length;

[0214] Case 2: The activation time delay of the first cell additionally considers the time length of the overlapping part between the time length between the start time point of T HARQ and the first time point and the fourth time length.

[0215] The implementation of the case that the time length between the start time point of T HARQ and the first time point overlaps with the fourth time length can refer to the description of the implementation of the case that the time length between the start time point of T HARQ and the first time point overlaps with the third time length, which will not be described here.

[0216] In some embodiments, if the time length between the start time point of T HARQ and the first time point overlaps with the third time length and the fourth time length, the activation time delay of the first cell is determined according to one of the following cases:

[0217] Case 1: The activation time delay of the first cell does not additionally consider the time length of the overlapping part between the time length between the start time point of T HARQ and the first time point and the third time length and the fourth time length;

[0218] Case 2: The activation time delay of the first cell additionally considers the time length of the overlapping part between the time length between the start time point of T HARQ and the first time point and the third time length and the fourth time length.

[0219] The implementation of the case that the time length between the start time point of T HARQ and the first time point overlaps with the third time length and the fourth time length can refer to the description of the implementation of the case that the time length between the start time point of T HARQ and the first time point overlaps with the third time length, which will not be described here.

[0220] The start time of the third time length is the effective time of the first indication information (OD-SSB indication information), and the first time is T HARQ In this example, the terminal device is configured by the network device to measure in advance, that is, the first measurement method is used. Wherein, the items that the terminal device can measure in advance include AGC gain setting (D), cell search (E), time-frequency synchronization tracking (F), SSB processing margin (G), T CSI_reporting one or more of the partial time lengths (for example, the uncertainty time of obtaining the first available downlink CSI reference resource) in T

[0221] Figure 12 shows an example of terminal device measurement in advance. As shown in Figure 12, the time interval between the effective time of the first indication information and the first time (the time of receiving the activation command information of the first cell (that is, the secondary cell)) is greater than or equal to the sum of the AGC gain setting (D), the cell search (E), the time-frequency synchronization tracking (F), the SSB processing margin (G), and the uncertainty time (L1) of the first available downlink CSI reference resource that the terminal device needs to perform, so the length of the third time length is T adv_act , wherein T adv_act =D+E+F+G, the length of the fourth time length is T adv_CSI , wherein T adv_CSI =L1. Accordingly, the terminal device determines that at the activation delay of the first cell, the third time length and the fourth time length should be subtracted. That is, the activation delay of the first cell is determined by T HARQ , T activation_time , and T CSI_reporting . It can be understood that in the example of Figure 12, T HARQ , the third time length and the fourth time length do not overlap in the time domain, and Figure 12 omits T HARQ . That is, in this case, the time delay of the terminal device that should be able to activate the first cell is:

[0222] In the case of receiving the activation command information of the first cell on the time slot n, the terminal device should be able to transmit valid CSI reporting and be able to communicate on the first cell according to the activation command information no later than the time slot n+((T HARQ +3+T CSI_reporting -L1) / NR slot length).

[0223] The start time of the third time length is the effective time of the first indication information (OD-SSB indication information), and the first time is T HARQThe end time of the first time interval is taken as an example to illustrate the embodiments of the present application. In this example, the terminal device is configured by the network device to measure in advance, i.e., the first measurement mode is used. The items that can be measured in advance by the terminal device include AGC gain setting (D), cell search (E), time-frequency synchronization tracking (F), SSB processing margin (G), and T CSI_reporting (L).

[0224] FIG. 13 illustrates another example of the terminal device measuring in advance. As shown in FIG. 13, the time interval between the validity time of the first indication information and the first time (the time at which the activation command information of the first cell (i.e., the secondary cell) is received) is greater than or equal to the sum of the AGC gain setting (D), the cell search (E), the time-frequency synchronization tracking (F), the SSB processing margin (G), and the T CSI_reporting duration (L), so the length of the third duration is T adv_act , and the length of the fourth duration is T adv_act , where T adv_CSI = D + E + F + G, and T adv_CSI = L. Accordingly, the terminal device determines that, at the activation delay of the first cell, the third duration and the fourth duration should be subtracted. That is, the activation delay of the first cell is determined by the T HARQ duration and the T activation_time duration of the MAC CE processing and the radio frequency (RF) warm-up margin (i.e., 3 ms). It can be understood that, in the example of FIG. 13, the T HARQ duration does not overlap with the third duration and the fourth duration in the time domain, and the T HARQ duration is omitted in FIG. 13. That is, in this case, the time delay at which the terminal device should be able to activate the first cell is:

[0225] In the case where the activation command information of the first cell is received on the time slot n, the terminal device should be able to transmit a valid CSI report and be able to communicate on the first cell according to the activation command information no later than the time slot n + ((T HARQ + 3) / NR time slot length).

[0226] Through the above method, for the first measurement mode, the terminal device can measure in advance before receiving the activation command information of the secondary cell, so that the activation delay of the secondary cell does not include the third duration and / or the fourth duration described above, and the activation delay of the secondary cell is reduced.

[0227] In some embodiments, the activation delay of the first cell includes a fifth duration.

[0228] In some embodiments, in the case that the terminal device receives the first indication information before receiving the activation command information of the first cell, the measurement manner of the terminal device on the first cell is the second measurement manner, and the activation delay of the first cell comprises a fifth time length.

[0229] In some embodiments, the fifth time length is determined based on one of the following time lengths: a time interval between the terminal device receiving the activation command information of the first cell and receiving the first indication information; a time interval between the terminal device receiving the activation command information of the first cell and an effective time of the first indication information; a time interval between the first time and the terminal device receiving the first indication information; and a time interval between the first time and the effective time of the first indication information.

[0230] In some embodiments, the unit of the fifth time length is ms or the length of an NR slot.

[0231] FIG. 14 shows an example in which the terminal device receives the first indication information before receiving the activation command information of the first cell. As shown in FIG. 14, the fifth time length is a time interval between the first time and the effective time of the first indication information. In this example, the first time is a time after the end time of the uplink channel carrying the HARQ-ACK information corresponding to the activation command information of the first cell plus 3 ms. Accordingly, the terminal device determines that the activation delay of the first cell should be added by the fifth time length. That is, the activation delay of the first cell is determined by T HARQ , the time length T activation_time , the time length T CSI_reporting , and the fifth time length. That is, in this case, the time delay in which the terminal device should be able to activate the first cell is:

[0232] In the case of receiving the activation command information of the first cell on the slot n, the terminal device should be able to transmit valid CSI reporting and be able to communicate on the first cell according to the activation command information no later than the slot n+((T HARQ +T activation_time +T CSI_reporting + the fifth time length) / the length of an NR slot.

[0233] Through the above method, in the case that the terminal device receives the first indication information before receiving the activation command information of the first cell, the activation delay of the first cell is added by the time length between receiving the activation command information and receiving the first indication information.

[0234] In some embodiments, the terminal device determines, according to the first SSB burst, at least one of: a time length of an AGC gain setting, a time length of a cell search, a time length of time-frequency synchronization tracking, a time length of an SSB processing margin, an uncertainty time of acquiring a first available downlink CSI reference resource, a terminal processing time of CSI reporting, an uncertainty time of acquiring a first available CSI reporting resource. For the determination manner of each time length, refer to the foregoing description, which will not be repeated here.

[0235] It should be noted that, in the foregoing method embodiments, the technical solutions of the present application are described from the perspective of the interaction between the terminal device and the network device. The steps performed by the terminal device described above can be implemented alone as a wireless communication method on the terminal device side, and the steps performed by the network device described above can be implemented alone as a wireless communication method on the network device side.

The device can be the terminal device described above or can be arranged in the terminal device. As shown in FIG. 15, the device 1500 can include a receiving module 1510.
