[0021] In an embodiment of the present invention, the term "communication network" or "wireless communication network" may refer to a network conforming to any communication standard, such as LTE (Long Term Evolution), LTE-Advanced (LTE-A), WCDMA (Wideband Code Division Multiple Access), HSPA (High-Speed ​​Packet Access), etc.

[0023] In the embodiment of the present invention, the term "network device" refers to a device that connects a terminal device to a communication network and provides services to the terminal device in a communication system, for example. The network device may include, but is not limited to, a base station (BS), an access point (AP), a transmission reception point (TRP), a broadcast transmitter, a mobile management entity (MME), a network gateway, a server, a radio network controller (RNC), a base station controller (BSC), etc.

[0024] Among them, the base station may include, but is not limited to, a Node B (NodeB or NB), an evolved Node B (eNodeB or eNB), a 5G base station (gNB), and may further include a Remote Radio Head (RRH), a Remote Radio Unit (RRU), a relay, or a low power node (e.g., femto, pico, etc.). The term "base station" may include some or all of the functions thereof, and each base station may provide communication coverage for a particular geographical area. The term "cell" may refer to a base station and / or the area it covers, depending on the context of the term.

[0025] In the embodiments of the present invention, the term "User Equipment" (UE) or "Terminal Equipment" (TE) refers to a device that accesses a communication network and receives services from the network, for example, via a network device. The User Equipment may be fixed or mobile, and may also be called a Mobile Station (MS), a terminal, a Subscriber Station (SS), an Access Terminal (AT), a station, etc.

[0027] Furthermore, in scenarios such as the Internet of Things (IoT), the user equipment may also be a monitoring or measuring device or equipment, including, but not limited to, a Machine Type Communication (MTC) terminal, an in-vehicle communication terminal, a Device to Device (D2D) terminal, a Machine to Machine (M2M) terminal, etc.

[0028] To clarify the embodiments of the present invention, some concepts and definitions related to the embodiments of the present invention are described below.

[0029] In the embodiment of the present invention, the transmission of an uplink signal based on a subslot refers to a terminal device transmitting an uplink signal in a certain subslot based on a corresponding instruction message. Generally speaking, "one uplink signal is transmitted in one subslot" refers to at least the start symbol of the uplink signal being in the subslot. The start symbol and the end symbol of the uplink signal may be in the subslot; or the start symbol of the uplink signal may be in the subslot, and the end symbol of the uplink signal may not be in the subslot (it may be in the subsequent subslot). In the embodiment of the present invention, the former (the start and end symbols of the uplink signal are both in the same subslot) is taken as an example for explanation.

[0030] In an embodiment of the present invention, the time domain length of a sub-slot is less than 14 symbols.

[0031] A terminal device receives a configuration message (e.g., subslotLengthForPUCCH) transmitted by a network device. The configuration message indicates the length of a subslot corresponding to a subslot-based uplink signal (e.g., PUCCH feedback). The unit of the length is a symbol. Generally speaking, the length of a subslot indicated by the indication message may be 7 symbols or 2 symbols. FIG. 1 illustrates one division method of a slot (the length corresponding to a subslot is 7 symbols). As shown in FIG. 1, one 14-symbol slot is divided into two 7-symbol subslots. Among them, uplink signal #1 is transmitted in subslot #0, while uplink signal #2 is transmitted in subslot #1. FIG. 2 illustrates another division method of a slot. As shown in FIG. 2 (the length corresponding to a subslot is 2 symbols), one 14-symbol slot is divided into seven 2-symbol subslots. Among them, uplink signal #1 is transmitted in subslot #1, while uplink signal #2 is transmitted in subslot #4.

[0032] Also, currently, activation or deactivation of a secondary cell (Scell) is indicated by MAC CE (medium access control unit) signaling, which can be carried in a PDSCH (physical downlink shared channel), and the terminal device can determine the time of subsequent actions by referring to the slot corresponding to the PUCCH transmission, for example: If the terminal device receives one PDSCH in time unit n, and the PDSCH includes one signaling for activation or deactivation of a secondary cell, and the PDSCH ends in slot n, the terminal device: applies the corresponding actions, e.g., corresponding secondary cell activation or deactivation actions, no earlier than time unit n+k+1; and / or apply an action on the deactivation timer of the secondary cell at time unit n+k+1; and / or Apply an action regarding the CSI report after time unit n+k, for example, apply an action regarding the CSI report one time unit after time unit n+k, where the time unit refers to the earliest slot among the slots in which the CSI report is in an active state.

[0033] The above k can be calculated by the following formula:

number

[0034] Where: (outside 1) TIFF0007597291000002.tif20153 is the number of slots included in each subframe when the SCS (subcarrier spacing) corresponding to the transmission of an uplink control signal (e.g., transmission of a PUCCH) is set to μ; and k1 is indicated by the PDSCH-to-HARQ_feedback timing indicator field in the scheduling DCI corresponding to the above-mentioned PDSCH.

[0035] The inventor has found the following: That is, when a terminal device receives a PDSCH including SCell activation signaling in slot n, the terminal device executes a corresponding terminal action in slot n+k+1, or does not execute a corresponding terminal action earlier than slot n+k+1 (executes a corresponding terminal action after slot n+k+1). However, when a subslot-based PUCCH configuration message (e.g., subslotLengthForPUCCH) is configured in the terminal device, the unit corresponding to k1 is a subslot, not a slot, so k cannot be accurately represented, and there is a risk that the system will not be able to work.

[0036] To avoid any ambiguity in indicating when the above-mentioned terminal actions take effect, a method is provided in an embodiment of the present invention.

[0037] Various embodiments of the present invention will now be described with reference to the drawings. Note that these embodiments are merely illustrative and do not limit the present invention.

[0038] <Example of the first aspect> In an embodiment of the first aspect of the present invention, a wireless communication method is provided, which is described from the terminal device side. Figure 3 illustrates a wireless communication method in an embodiment of the present invention. As shown in Figure 3, the method includes the following steps:

[0039] 301: A terminal device receives a downlink data signal at a time unit n, the downlink data signal including an activation or deactivation signaling (activation / deactivation command) acting on one secondary cell; and 302: The terminal device performs at least one of the following processes: not applying a corresponding action earlier than time unit n+k+1; applying an action related to a deactivation timer of the secondary cell in time unit n+k+1; and applying an action related to a CSI report after time unit n+k, wherein the CSI report is related to or corresponds to the activation or deactivation signaling.

[0040] In the embodiment of the present invention, the time unit refers to a time unit corresponding to the transmission of an uplink control signal carrying a HARQ-ACK message corresponding to the downlink data signal, i.e., the above-mentioned time unit refers to a time unit corresponding to an uplink control signal carrying a HARQ-ACK message corresponding to the downlink data signal.

[0041] According to the above-mentioned method in the embodiment of the present invention, after the terminal device receives a downlink data signal in time unit n, it refers to a time unit corresponding to the transmission of an uplink control signal carrying a HARQ-ACK message corresponding to the downlink data signal, and applies a corresponding action no earlier than time unit n+k+1; or applies an action related to the deactivation timer of the secondary cell in time unit n+k+1; or applies an action related to a CSI report after time unit n+k, thereby avoiding incorrect or ambiguous indications regarding activation or deactivation of the downlink data signal.

[0042] In an embodiment of the present invention, receiving a downlink data signal in time unit n may be equivalent to the terminal device receiving a downlink data signal that ends in time unit n. In an embodiment of the present invention, the number of symbols included in the time unit may be less than 14, may be called a subslot, or may be called by other names, but the present invention is not limited thereto.

[0043] In an embodiment of the present invention, the above-mentioned downlink data signal is, for example, a PDSCH or a signal carried by a PDSCH; the above-mentioned uplink control signal is, for example, a PUCCH or a signal carried by a PUCCH, but the present invention is not limited thereto.

[0044] In some embodiments, k is the number of time units contained in one 14-symbol slot ( (outside 2) For example, as shown in FIG. 1, one 14-symbol slot may be divided into two 7-symbol subslots, i.e., one 14-symbol slot includes two subslots:

[0045] In some embodiments, k may be calculated according to the following formula:

[0046] According to the above embodiment, the effective time of the corresponding action is clarified by referring to the uplink control signal carrying the HARQ-ACK message, thereby avoiding ambiguity in the terminal device action and improving system stability. In some embodiments, as in the examples of FIGS. 1 and 2, where a 14 symbol slot can be integer partitioned,

[0047] In some embodiments, if a 14 symbol slot cannot be divided evenly,

[0049] In the embodiments of the present invention, applying a corresponding action refers to applying an action related to or corresponding to the activation or deactivation signaling, for example, applying a corresponding SCell activation or deactivation action. In some embodiments, adapting a corresponding action does not include applying an action related to CSI reporting. In some embodiments, applying a corresponding action does not include applying an action related to the above-mentioned SCell deactivation timer of the secondary cell. The specific content of the action can be referred to in the related art, and therefore a detailed description thereof will be omitted here.

[0050] In some embodiments, applying the action on the CSI report after time unit n+k includes applying the action on the CSI report at one time unit after time unit n+k, where the one time unit after time unit n+k may be the earliest time unit in which the CSI report is active after time unit n+k.

[0051] In some embodiments, applying an action related to the CSI report after time unit n+k includes applying an action related to the CSI report at one time unit after time unit n+k, where the one time unit after time unit n+k is time unit n+k+1, in which the CSI report is active at time unit n+k+1.

[0052] In some embodiments, applying the action on the CSI report after time unit n+k includes applying the action on the CSI report at one time unit after time unit n+k, where the one time unit after time unit n+k is the earliest time unit in which the CSI report is active after time unit n+k+1, where the CSI report is not active at time unit n+k+1.

[0053] Hereinafter, embodiments of the present invention will be described with reference to the drawings.

[0054] FIG. 4 is a diagram showing a slot of cell 1. Wherein, the subcarrier spacing (SCS) of cell 1 is 15 kHz. As shown in FIG. 4, according to the subslot-based configuration message (subslotLengthForPUCCH), one slot is divided into two subslots (each subslot includes 7 symbols). In cell 1, a UE receives one PDSCH including an SCell activation command in subslot #0 of slot #0. According to the indication message, the UE feeds back a HARQ-ACK message corresponding to the PDSCH in subslot #0 of slot #0 (transmits a PUCCH carrying the HARQ-ACK message). By substituting the related messages into the above formula, it can be seen that the UE applies the action related to SCell activation / deactivation after subslot #1 of slot #30. Here, the action related to SCell activation does not include the action related to CSI reporting, nor the action related to the SCell deactivation timer.

[0055] FIG. 5 is another diagram showing a slot of cell 1, in which the subcarrier spacing (SCS) of cell 1 is 15 kHz. As shown in FIG. 5, according to the subslot-based configuration message (subslotLengthForPUCCH), one slot can be divided into two subslots (each subslot includes 7 symbols). In cell 1, the UE receives one PDSCH containing an SCell activation command in slot #0. According to the indication message, the UE feeds back a HARQ-ACK message corresponding to the PDSCH in subslot #0 of slot #0 (sends a PUCCH carrying the HARQ-ACK message). By substituting the above formula for the relevant message, the UE applies an action on the SCell deactivation timer in subslot #1 of slot #30.

[0056] FIG. 6 shows slots of cell 1 and cell 2. The subcarrier spacing (SCS) of cell 1 and cell 2 is 15 kHz. In cell 1, one slot can be divided into two subslots (each subslot includes 7 symbols) according to the subslot-based configuration message (subslotLengthForPUCCH). As for cell 2, the CSI reporting is slot-based. In cell 1, the UE receives a PDSCH containing an SCell activation command in subslot #0 of slot #0, which is used to activate cell 2. Based on the indication message, the UE feeds back a HARQ-ACK message corresponding to the PDSCH in subslot #0 of slot #0 (transmits a PUCCH carrying the HARQ-ACK message). By substituting the relevant message into the above formula, the UE applies the action related to CSI reporting after subslot #0 of slot #30. Also, if activation of CSI reporting starts in slot #31 (of cell 2), the UE starts applying the action on the CSI reporting in sub-slot #0 of slot #31 (of reference cell 1).

[0057] FIG. 7 is another diagram showing slots of cell 1 and cell 2, in which the subcarrier spacing (SCS) of cell 1 is 15 kHz, and the subcarrier spacing (SCS) of cell 2 is 30 kHz. In cell 1, one slot can be divided into two subslots (each subslot includes 7 symbols) based on the subslot-based configuration message (subslotLengthForPUCCH). As for cell 2, the CSI reporting is slot-based. In cell 1, the UE receives one PDSCH containing an SCell activation command in subslot #0 of slot #0, and the activation command is used to activate cell 2. Based on the indication message, the UE feeds back a HARQ-ACK message corresponding to the PDSCH in subslot #0 of slot #0 (sends a PUCCH carrying the HARQ-ACK message). By substituting the relevant message into the above formula, it can be seen that the UE applies the action related to CSI reporting after subslot #0 of slot #30. Also, if activation of CSI reporting starts in slot #61 (of cell 2), the UE applies the action for the CSI reporting in sub-slot #1 of slot #30 (of reference cell 1).

[0058] FIG. 8 is another diagram showing slots of cell 1 and cell 2 in FIG. 7, in which the subcarrier spacing (SCS) of cell 1 is 15 kHz, and the subcarrier spacing (SCS) of cell 2 is 30 kHz. In cell 1, one slot can be divided into two subslots (each subslot includes 7 symbols) based on the subslot-based configuration message (subslotLengthForPUCCH). As for cell 2, the CSI report is slot-based. In cell 1, the UE receives one PDSCH containing a SCell deactivation command in subslot #0 of slot #0, which is used to deactivate cell 2. Based on the indication message, the UE feeds back a HARQ-ACK message corresponding to the PDSCH in subslot #0 of slot #0 (transmits a PUCCH carrying the HARQ-ACK message). As can be seen by substituting the relevant messages into the above formula, the UE applies the action related to CSI reporting after subslot #0 of slot #30. For example, the UE deactivates the action related to CSI reporting in subslot #1 of slot #30 (of reference cell 1) or in slot #61 (of reference cell 2).

[0059] As described above, the method according to the embodiment of the present invention can improve the stability of the system.

[0075] 1001: A terminal device receives a downlink data signal in a time unit n, the downlink data signal including activation or deactivation signaling acting on one secondary cell; and 1002: The terminal device performs at least one of the following processes: not applying a corresponding action earlier than time unit n+k+1; applying an action related to a deactivation timer of the secondary cell in time unit n+k+1; and applying an action related to a CSI report after time unit n+k, wherein the CSI report is related to or corresponds to the activation or deactivation signaling.

[0076] In the embodiment of the present invention, the time unit refers to a time unit corresponding to the transmission of an uplink control signal, that is, the above-mentioned time unit refers to a time unit corresponding to the uplink control signal.

[0077] According to the above-mentioned method in the embodiment of the present invention, after the terminal device receives a downlink data signal in time unit n, it refers to a time unit corresponding to the transmission of an uplink control signal, and applies the corresponding action no earlier than time unit n+k+1; or applies the above-mentioned action related to the deactivation timer of the secondary cell in time unit n+k+1; or applies the action related to the CSI report after time unit n+k, thereby avoiding incorrect or ambiguous instructions for activation or deactivation of the downlink data signal.

[0078] In an embodiment of the present invention, receiving a downlink data signal in time unit n may mean that the terminal device receives a downlink data signal that ends in time unit n. In an embodiment of the present invention, the number of symbols included in the time unit may be 14, and may be called a slot or other names, but the present invention is not limited thereto.

[0079] In an embodiment of the present invention, the above-mentioned downlink data signal is, for example, a PDSCH or a signal carried by a PDSCH; the above-mentioned uplink control signal is, for example, a PUCCH or a signal carried by a PUCCH, but the present invention is not limited thereto.

[0080] In some embodiments, k refers to a slot interval or offset between the downlink data signal and an uplink control signal carrying a HARQ-ACK message corresponding to the downlink data signal.

[0081] In some embodiments, k is calculated based on the following formula:

number

[0082] The above embodiment clarifies the slot interval between the PDSCH carrying SCell activation / deactivation signaling and the PUCCH carrying the HARQ-ACK message corresponding to the PDSCH by referring to the PUCCH, thereby enabling the UE to accurately identify (position) the effective time point of the corresponding action, thereby avoiding ambiguity in UE actions and improving system stability.

[0083] In the embodiments of the present invention, applying a corresponding action refers to applying an action related to or corresponding to the activation or deactivation signaling, for example, applying a corresponding SCell activation or deactivation action. In some embodiments, applying the corresponding action does not include applying an action related to CSI reporting. In some embodiments, applying the corresponding action does not include applying an action related to the above-mentioned SCell deactivation timer of the secondary cell. For specific contents of the actions, reference may be made to related art, and detailed descriptions thereof will be omitted here.

[0084] In some embodiments, applying an action regarding the CSI report after time unit n+k includes applying an action regarding the CSI report one time unit after time unit n+k, where the one time unit after time unit n+k refers to the earliest time unit among the time units in which the CSI report is active after time unit n+k.

[0085] In some embodiments, applying an action related to the CSI report after time unit n+k includes applying an action related to the CSI report at one time unit after time unit n+k, the one time unit after time unit n+k being time unit n+k+1, in which the CSI report is active at time unit n+k+1.

[0086] In some embodiments, applying the action on the CSI report after time unit n+k includes applying the action on the CSI report at one time unit after time unit n+k, where the one time unit after time unit n+k is the earliest time unit in which the CSI report is active after time unit n+k+1, where the CSI report is not active at time unit n+k+1.

[0087] Hereinafter, embodiments of the present invention will be described with reference to the drawings.

[0088] FIG. 11 shows a slot of cell 1, in which the subcarrier spacing (SCS) of cell 1 is 15 kHz. As shown in FIG. 11, one slot can be divided into two subslots (each subslot includes 7 symbols) according to a subslot-based configuration message (subslotLengthForPUCCH). In cell 1, a UE receives one PDSCH including an SCell activation command in slot #0. According to an indication message, the UE feeds back a HARQ-ACK message corresponding to the PDSCH in slot #0 (transmits a PUCCH carrying the HARQ-ACK message). As can be seen by substituting the related messages into the above formula, the UE applies actions related to SCell activation / deactivation from slot #31 onwards. Here, the actions related to SCell activation do not include actions related to CSI reporting, nor actions related to the SCell deactivation timer.

[0089] In the example of Figure 11, k'1 refers to the slot offset between the PDSCH and the corresponding PUCCH carrying the HARQ-ACK message. Because the PDSCH and the corresponding PUCCH carrying the HARQ-ACK message are in the same slot, k'1 = 0.

[0090] FIG. 12 is another diagram showing a slot of cell 1, in which the subcarrier spacing (SCS) of cell 1 is 15 kHz. As shown in FIG. 12, according to the subslot-based configuration message (subslotLengthForPUCCH), one slot can be divided into two subslots (each subslot includes 7 symbols). In cell 1, the UE receives one PDSCH containing an SCell activation command in slot #0. According to the indication message, the UE feeds back a HARQ-ACK message corresponding to the PDSCH in slot #0 (sends a PUCCH carrying the HARQ-ACK message). By substituting the related message into the above formula, the UE applies an action on the SCell deactivation timer in slot #31.

[0091] In the example of Figure 12, k'1 refers to the slot offset between the PDSCH and the corresponding PUCCH carrying the HARQ-ACK message. Because the PDSCH and the corresponding PUCCH carrying the HARQ-ACK message are in the same slot, k'1 = 0.

[0092] FIG. 13 shows slots of cell 1 and cell 2, in which the subcarrier spacing (SCS) of cell 1 and cell 2 is all 15 kHz. As shown in FIG. 13, in cell 1, one slot can be divided into two subslots (each subslot includes 7 symbols) based on the subslot-based configuration message (subslotLengthForPUCCH). As for cell 2, the CSI reporting is slot-based. In cell 1, the UE receives one PDSCH containing an SCell activation command in slot #0, and the activation command is used to activate cell 2. Based on the indication message, the UE feeds back a HARQ-ACK message corresponding to the PDSCH in slot #0 (transmits a PUCCH carrying the HARQ-ACK message). By substituting the relevant message into the above formula, the UE applies the action related to CSI reporting after slot #30. Also, if activation of CSI reporting starts in slot #31 (of cell 2), the UE applies the action on the CSI reporting in slot #31 (of reference cell 1).

[0093] In the example of Figure 13, k'1 refers to the slot offset between the PDSCH and the corresponding PUCCH carrying the HARQ-ACK message. Because the PDSCH and the corresponding PUCCH carrying the HARQ-ACK message are in the same slot, k'1 = 0.

[0094] FIG. 14 is another diagram showing slots of cell 1 and cell 2, in which the subcarrier spacing (SCS) of cell 1 is 15 kHz, and the subcarrier spacing (SCS) of cell 2 is 30 kHz. As shown in FIG. 14, in cell 1, one slot can be divided into two subslots (each subslot includes 7 symbols) based on the subslot-based configuration message (subslotLengthForPUCCH). As for cell 2, the CSI reporting is slot-based. In cell 1, the UE receives one PDSCH containing an SCell activation command in slot #0, and the activation command is used to activate cell 2. Based on the indication message, the UE feeds back a HARQ-ACK message corresponding to the PDSCH in slot #0 (sends a PUCCH carrying the HARQ-ACK message). By substituting the relevant message into the above formula, the UE applies the action related to CSI reporting after slot #30. Also, if activation of CSI reporting starts in slot #62 (of cell 2), the UE applies the action on the CSI reporting in slot #31 (of reference cell 1).

[0095] In the example of Figure 14, k'1 refers to the slot offset between the PDSCH and the corresponding PUCCH carrying the HARQ-ACK message. Even if the PDSCH and the corresponding PUCCH carrying the HARQ-ACK message are in different subslots, k'1 = 0 because they are in the same slot.

[0096] FIG. 15 is another diagram showing slots of cell 1 and cell 2, in which the subcarrier spacing (SCS) of cell 1 is 15 kHz, and the subcarrier spacing (SCS) of cell 2 is 30 kHz. As shown in FIG. 15, in cell 1, one slot can be divided into two subslots (each subslot includes 7 symbols) based on the subslot-based configuration message (subslotLengthForPUCCH). As for cell 2, the CSI reporting is slot-based. In cell 1, the UE receives one PDSCH containing a SCell deactivation command in slot #0, which is used to deactivate cell 2. Based on the indication message, the UE feeds back a HARQ-ACK message corresponding to the PDSCH in slot #0 (sends a PUCCH carrying the HARQ-ACK message). By substituting the relevant messages into the above formula, the UE applies the action related to CSI reporting after slot #30. For example, the UE deactivates the action related to the CSI report in slot #31 (of reference cell 1) or slot #62 (of reference cell 2).

[0097] In the example of Figure 15, k'1 refers to the slot offset between the PDSCH and the corresponding PUCCH carrying the HARQ-ACK message. Even if the PDSCH and the corresponding PUCCH carrying the HARQ-ACK message are in different subslots, k'1 = 0 because they are in the same slot.

[0098] As described above, the method according to the embodiment of the present invention can improve the stability of the system.
