[0062] The present application is further described in detail below in conjunction with the accompanying drawings and embodiments.

[0063] In the research on network energy saving, the DTX or DRX technology of the cell is introduced for the energy saving technology of the base station time domain. By introducing the base station inactive period in the time domain to reduce the transmission of some periodic signals, the terminal (also called UE) is not scheduled, so as to achieve energy saving of the base station. Specifically, Figure 1 As shown, for the DTX or DRX of a cell, relevant parameters such as cycle, start offset (which can be expressed as start offset in English), slot offset (which can be expressed as slotoffset in English), duration (which can be expressed as on duration in English) are introduced to determine the time position, time length, etc. of the activation period (which can be expressed as active in English) and the non-activation period (which can be expressed as non active in English) within the DTX or DRX cycle of a cell.

[0064] In order to realize the activation or deactivation of DTX or DRX of a cell, one implementation method is that once the DTX or DRX related parameters of a cell are configured through Radio Resource Control (RRC) signaling, the DTX or DRX of the cell will be activated until the corresponding related parameters of other cells are configured through RRC signaling, then the DTX or DRX of other cells will be activated. In addition, if the related configuration is released through RRC signaling, the DTX or DRX of the cell is also deactivated accordingly.

[0065] Specifically, after the UE receives the DTX or DRX related parameters of the cell, it can perform transmission behavior during the DTX or DRX activation period and the inactive period of the cell based on the mode (expressed as pattern in English) corresponding to the related parameters. For example, during the DTX or DRX activation period of the cell, the UE can receive the uplink or downlink scheduling PDCCH, and perform periodic reception and transmission behavior; during the DTX or DRX inactive period of the cell, the UE may not perform detection for PDCCH (specifically detection of PDCCH in USS), detection of type3-PDCCH, reporting of periodic channel state information (CSI, Channel State Information), sending of periodic channel sounding reference signal (SRS, Sounding Reference Signal), transmission of CG-PUSCH, and transmission of semi-persistent scheduling physical downlink shared channel (SPS-PDSCH, Semi-Persistent Scheduling-Physical Downlink Shared CHannel).

[0066] However, with this activation method configured by RRC signaling, the effective time of RRC signaling reaches the order of tens of milliseconds (ms), which makes it difficult to respond to dynamic changes in services in a timely manner. Therefore, it is proposed to use layer 1 (L1) signaling to activate or deactivate DTX or DRX of a cell; among them, PDCCH can be used based on group common L1 signaling to achieve more dynamic activation or deactivation. However, how to achieve dynamic activation or deactivation based on PDCCH requires more detailed design.

[0067] Among them, a specific implementation method is: it can refer to the design of downlink control information (DCI, Downlink Control Information) format (format) 2_6; wherein, DCI format 2_6 is used for energy-saving indication of the terminal, and indicates to a group of UEs whether they need to be awakened when the next DRX duration timer (which can be expressed as onduration timer in English) starts through the group-common DCI; wherein, the information field of DCI format 2_6 can include multiple blocks (which can be expressed as blocks in English), and each block will have a number (which can be expressed as number in English), such as Block number 1, block number 2. When a UE is configured to detect DCI format 2_6, a block will be configured for the UE through high-level signaling, and the ps-Position DCI-2_6 field in the RRC signaling will be used to configure the starting position of the terminal block, so that the terminal can read the information of the corresponding block to obtain the energy-saving indication. The information of the block can specifically include the following two parts:

[0068] One part is a wake-up indication (1 bit), which is used to indicate whether the UE starts the DRX duration timer at the start time of the DRX cycle (which can be expressed as cycle in English). If it does not need to be started, the UE can skip unnecessary PDCCH detection, thereby achieving UE energy saving;

[0069] One part is the secondary cell dormancy (Scell ​​dormancy in English). If this function is not configured, the corresponding bit is set to 0. If this function is configured, the dormancy status of different secondary cell groups is indicated according to the number of configured secondary cell groups. For example, the dormancy status of up to 5 secondary cell groups can be indicated by 5 bits.

[0070] Here, the DTX or DRX activation or deactivation of the cell can be realized dynamically through PDCCH indication. After activating DTX or DRX, the UE can transmit data according to the transmission behavior during the activation period and the non-activation period; after deactivating DTX or DRX, the transmission behavior of the network side (specifically, the base station) and the UE is no longer constrained based on the DTX or DRX related parameters of the cell, that is, the transmission behavior at this time corresponds to the transmission behavior when the base station does not configure the DTX or DRX activation or deactivation of the cell.

[0071] It can be seen from the above description that DCI format 2_6 is used for UE wake-up indication. Since the wake-up state of each UE is different, different UEs correspond to different blocks in DCI format 2_6, so that the wake-up state indication of different UEs can be realized. However, the activation or deactivation of DTX or DRX of a cell is a cell-level behavior, and it is necessary to indicate the activation state of different cells, rather than the UE-level (i.e., each UE (English can be expressed as per UE)) behavior. Therefore, the indication method of DCI format 2_6 is not applicable, and there is no need to define a different starting position for each terminal.

[0072] Based on this, in various embodiments of the present application, the network side configures the position of the DTX and DRX activation or deactivation bits of the cell for the terminal, so that the terminal can determine the activation status of DRX and / or DTX of different service cells from the DCI in the case of multiple service cells, thereby realizing the indication of DRX and / or DTX activation or deactivation of the cell, and further realizing the RTX or DRX activation or deactivation of the cell.

[0073] The present application embodiment provides an information indication method, which is applied to a terminal, such as Figure 2 As shown, the method includes:

[0074] Step 201: Receive DCI, where the DCI is used to indicate activation or deactivation of DTX and / or DRX of at least one cell; wherein the terminal is configured with the position of the DTX activation or deactivation bit of the cell and / or the DRX activation or deactivation bit in the DCI.

[0075] In actual application, the terminal can be called UE, terminal equipment, equipment or user, etc. The embodiment of the present application does not limit the name of the terminal as long as its function is realized.

[0076] It should be noted that, in the embodiment of the present application, the cell may be referred to as a serving cell (which may be expressed as a serving cell in English), and accordingly, for the terminal, the DTX activation or deactivation bit and / or the position of the DRX activation or deactivation bit of the serving cell of the terminal in the DCI is configured for the terminal. In actual application, in a multi-carrier scenario, the serving cell of the terminal may include at least one.

[0077] Since the DCI indicates the activation or deactivation of DTX and / or DRX at the cell level, rather than the activation or deactivation of DTX and / or DRX at the UE level, the DCI can be understood as a group-based DCI signaling. Therefore, exemplarily, the format of the DCI (which can be expressed as format in English) can be expressed as DCI format 2_x. The embodiment of the present application does not limit the format of the DCI, as long as its function is implemented.

[0078] Here, the terminal is configured with the position of the DTX activation or deactivation bit and / or the DRX activation or deactivation bit of the cell in the DCI, which means that the network side configures the position of the DTX activation or deactivation bit and / or the DRX activation or deactivation bit of the cell in the DCI for the terminal. In actual application, in order to enable the terminal to obtain the activation status of DTX and / or DRX of at least one serving cell from the DCI, the network side may configure the first information for the terminal, and the first information is used to indicate, that is, provide the position of the DTX activation or deactivation bit and / or the DRX activation or deactivation bit of the cell in the DCI. Specifically, when the DCI is used to indicate activation or deactivation of DTX of at least one cell, the first information is at least used to indicate the position of the DTX activation or deactivation bit of the cell in the DCI; when the DCI is used to indicate activation or deactivation of DRX of at least one cell, the first information is at least used to indicate the position of the DRX activation or deactivation bit of the cell in the DCI; when the DCI is used to indicate activation or deactivation of DTX and DRX of at least one cell, the first information is used to indicate the position of the DTX activation or deactivation bit and the DRX activation or deactivation bit of the cell in the DCI. The position can specifically be the starting position of the DTX activation or deactivation bit and / or the DRX activation or deactivation bit in the DCI.

[0079] Here, considering that the number of cells configured for each terminal may be different, and the primary cell (Pcell) of one terminal may be the secondary cell (Scell) of another terminal, the network side cannot directly define the correspondence between the block number (BN) (i.e., block identifier) ​​and the cell index in the DCI according to the order of the cell index (which can be expressed as cell index in English) (which can also be understood as the cell identifier). In order to identify the activation status of different cells, the correspondence between the block number and the cell index can be defined. Accordingly, in an embodiment of the present application, the first information may include a cell-related list (also referred to as a set), and for at least one serving cell of the terminal, each cell in the list (i.e., each member in the set) corresponds to a DTX and / or DRX activation or deactivation configuration of one cell, and the cell-related list may include a cell identifier (such as a cell ID, specifically a cell index) and the position of the cell's DTX activation or deactivation bit and / or DRX activation or deactivation bit in the DCI (specifically, the starting position); wherein, in actual application, the first information may be configured for the terminal through the PDCCH-config parameter in the RRC signaling, and this embodiment of the present application is not limited thereto. That is to say, in one embodiment, the first information may include the cell identifier of at least one cell and the starting position information of the DTX activation or deactivation bit and / or DRX activation or deactivation bit in the DCI.

[0080] In actual application, after receiving the first information through RRC signaling, the terminal can use the first information to obtain the activation status of each cell of the terminal from the DCI.

[0081] Based on this, Figure 2 As shown, in one embodiment, the method may further include:

[0082] Step 202: Determine whether to activate or deactivate DTX and / or DRX for a cell using first information and DCI, wherein the first information provides the position of the DTX activation or deactivation bit and / or DRX activation or deactivation bit of the cell in the DCI.

[0083] Here, for each cell of at least one cell of the terminal, the terminal can use the first information and the DCI to obtain the activation status of the corresponding cell, which may specifically include activating or deactivating DTX, activating or deactivating DRX, and activating or deactivating DRX and DTX.

[0084] For example, Figure 3As shown, assuming that the DCI contains 8 blocks, namely BN1, BN2, BN3, BN4, BN5, BN6, BN7 and BN8, it can indicate the activation or deactivation status of 8 cells. For UE1, it has 8 serving cells, and the first information indicates (can also be understood as configuring) the indexes of the 8 serving cells of UE1, namely: ServCell Index0, ServCell Index1, ServCell Index2, ServCell Index3, ServCell Index4, ServCellIndex5, ServCell Index6, ServCell Index7, and the position of the activation or deactivation bit of each serving cell in the DCI (the figure illustrates the positions of BN1, BN2 and BN7 corresponding to serving cells 1 (indexed as ServCell Index0), 2 (indexed as ServCellIndex1), and 8 (indexed as ServCell Index7), and the others are not illustrated), so UE1 can obtain the indication of activation or deactivation of DTX and / or DRX of the corresponding cell from the corresponding block of the DCI. For UE2, UE2 can obtain the indication of activation or deactivation of DTX and / or DRX of the corresponding cell from the corresponding block of the DCI based on the cell index indicated by the first information (ServCell Index0 and ServCell Index1, respectively) and the position of the activation or deactivation bit of the cell in the DCI (the bit position corresponding to BN2 and BN6, respectively). It is worth noting that each UE obtains its own first information, so the UE only needs to obtain its own serving cell and the position of the corresponding activation or deactivation bit.

[0085] Since the first information is sent by the network side, the first information provides the position of the DTX activation or deactivation bit and / or DRX activation or deactivation bit of the cell in the DCI, and can also be understood as the first information being used to indicate the position of the DTX activation or deactivation bit and / or DRX activation or deactivation bit of the cell in the DCI; the first information is specifically used to indicate the position of the DTX activation or deactivation bit and / or DRX activation or deactivation bit of the service cell of the terminal in the DCI.

[0086] The first information may specifically include a cell identifier (such as a cell index) of at least one cell and starting position information of a DTX activation or deactivation bit and / or a DRX activation or deactivation bit in the DCI. Specifically, each cell identifier corresponds to a DTX activation or deactivation bit and / or starting position information of a DRX activation or deactivation bit in the DCI.

[0087] In the related art, for the activation or deactivation behavior of a cell, independent bits are usually configured for activating or deactivating DTX and DRX. In this way, independent activation or deactivation of DTX and DRX can be achieved. The network side can configure only the cell DTX for the terminal, or only configure DRX, or configure both cell DTX and DRX at the same time. Specifically, when the network side configures only the cell DTX for the cell, each block in the DCI only needs to carry the DTX activation or deactivation bit of the cell; when the network side configures only DRX for the cell, each block in the DCI only needs to carry the DRX activation or deactivation bit of the cell. When the network side configures both cell DTX and DRX for the cell, each block in the DCI needs to carry the DTX activation or deactivation bit of the cell, and the DRX activation or deactivation bit.

[0088] In actual application, for the configuration of activating or deactivating DTX and / or DRX of a cell, there may be the following three scenarios: the cell activates DTX but does not activate DRX; the cell activates DRX but does not activate DTX; the cell activates DRX and DTX; the data transmission effect may be different in different scenarios.

[0089] Specifically, Figure 4 As shown in (a), when DTX is activated in the cell and DRX is not activated, the network side can continue to receive data, but the scheduling of downlink service data can only occur during the cell DTX activation period. If the terminal sends an SR request during the cell DTX inactivation period, it needs to enter the cell DTX activation period before the network side responds; if the terminal transmits CG-PUSCH during the cell DTX inactivation period, the network side also needs to schedule retransmission when entering the cell DTX activation period.

[0090] like Figure 4 As shown in (b), when DRX is activated in the cell but DTX is not activated, the terminal can be scheduled by the network side to transmit the physical downlink shared channel (PDSCH) at any time. However, the CSI report (expressed as report in English) reported by the terminal can only be received by the network side during the period when the cell DRX is activated, that is, the network side cannot obtain feedback on the PDSCH scheduling in time, which will lead to a decrease in the transmission efficiency of the PDSCH.

[0091] like Figure 4 As shown in (c), when DRX and DTX are activated in the cell, the network side has consistent behavior for uplink or downlink data transmission, which can better achieve the purpose of network energy saving. Compared with the above two cases, the energy saving effect in this case is the best.

[0092] It can be seen from the above description that, from the perspective of practical application, when DTX and DRX of a cell are configured at the same time, and the configurations of DRX and DTX, such as cycle, offset, etc., are the same, the impact on data transmission is small. Therefore, the DRX activation or deactivation bit and the DTX activation or deactivation bit of the cell can be shared (expressed as share in English, that is, the activation or deactivation of DRX and DTX are indicated at the same time through the same bit), so as to better achieve the purpose of energy saving on the network side.

[0093] Based on this, in one embodiment, for the at least one cell, the DTX activation or deactivation bit is the same as the DRX activation or deactivation bit.

[0094] In actual application, the activation or deactivation bit can be implemented by 1 bit (expressed as bit in English), that is, the two values ​​of a bit respectively represent the activation state or the deactivation state, for example, 0 represents the activation state, and 1 represents the deactivation state; of course, 1 can also represent the activation state and 0 represents the deactivation state, which is not limited to the embodiment of the present application.

[0095] Of course, when the DTX activation or deactivation bit is different from the DRX activation or deactivation bit, the activation or deactivation bit can be implemented by 2 bits, corresponding to the activation or deactivation of DTX and the activation or deactivation of DRX respectively.

[0096] After the terminal obtains the first information, it can determine the starting position for reading the activation or deactivation bit according to the first information. After determining the starting position, it can determine the indication of the activation or deactivation behavior of the cell's DTX and / or DRX according to the number of bits per block (the number of bits per block can be pre-set as needed, or the network side can pre-notify the terminal of the number of bits per block so that the terminal can obtain the number of bits per block, and the embodiments of the present application are not limited to this).

[0097] In addition, the activation or deactivation bit may be referred to as an activation or deactivation indication bit, or an activation indication bit, and the embodiments of the present application are not limited to this, as long as its function is achieved.

[0098] In actual application, in order to enable the terminal to know whether the cell DTX and DRX are configured to be activated or deactivated at the same time, in other words, in order to enable the terminal to know whether the cell DTX activation or deactivation bit and DRX activation or deactivation bit are configured to be the same, the network side needs to configure for the terminal whether the cell's DTX activation or deactivation bit and DRX activation or deactivation bit are shared.

[0099] Based on this, in one embodiment, the method may include:

[0100] Second information is received, where the second information is used to indicate that a DTX activation or deactivation bit and a DRX activation or deactivation bit of at least one of the at least one cells are the same.

[0101] Of course, the second information can also be used to indicate that the DTX activation or deactivation bit of the at least one cell is different from the DRX activation or deactivation bit. In this case, the cell DTX activation or deactivation bit is different from the DRX activation or deactivation bit, that is, the cell DTX and DRX are activated or deactivated independently.

[0102] Here, in actual application, the network side can configure the DRX activation or deactivation bit and DTX activation or deactivation bit sharing of the cell for the terminal through RRC signaling, that is, DTX and DRX use the same bit to achieve the purpose of activation or deactivation, that is, the terminal receives RRC signaling, and the RRC signaling contains the second information.

[0103] In actual application, exemplarily, when the second information is used to indicate that the DTX activation or deactivation bit of at least one cell in the at least one cell is the same as the DRX activation or deactivation bit, the second information may be 1-bit indication information, indicating whether to share, or start or enumeration information, and the enumeration is true (expressed as true in English) indicating that sharing is established, and the second information may also be configuration information for each cell, that is, each cell independently determines whether to apply the same bit (such as 1 bit) to indicate the activation or deactivation of DTX and DRX of the cell, and the second information may also be configuration information common to all cells, that is, all cells use one bit to indicate the activation or deactivation of DTX and DRX of the cell. Specifically, when the second information is set to start or true, the activation or deactivation of DTX and DRX of the cell can be simultaneously indicated by the same bit in the DCI, that is, the status of the two configurations is indicated by one bit. When the second information is the configuration information of each cell, it can be separately indicated for each cell in the at least one cell whether the DTX activation or deactivation bit is the same as the DRX activation or deactivation bit. When the second information is configured as cell-common information, all cells in the at least one cell can use the same bit (such as 1 bit) to indicate the DTX and DRX activation or deactivation of the cell, that is, the DTX activation or deactivation bit and the DRX activation or deactivation bit of all cells are the same.

[0104] Here, the amount of information carried by the PDCCH is reduced by sharing the DRX activation or deactivation bit and the DTX activation or deactivation bit of the cell. This not only reduces the PDCCH overhead (i.e., reduces the occupied bits), but also increases the reliability of the PDCCH. From the perspective of actual deployment, it is also more in line with the purpose of network energy saving.

[0105] In actual application, in the process of determining whether to activate or deactivate DTX and / or DRX in a cell, there may be a scenario where DCI is missed, as shown in Table 1, that is, the terminal does not detect the indication information for activating or deactivating DTX and / or DRX.

[0106] Scenario Current cell DTX / DRX status Missed detection indication 1 Cell DTX deactivation status Cell DTX activation indication 2 Cell DTX activation status Cell DTX deactivation indication 3 Cell DRX deactivation status Cell DRX activation indication 4 Cell DRX activation status Cell DRX deactivation indication

[0107] Table 1

[0108] Here, different missed detection scenarios may have different impacts. Specifically,

[0109] Scenario 1

[0110] During the period when the terminal enters the cell DTX non-activation (which can be expressed as non-active in English), the terminal will operate as if the cell DTX is in the deactivated state, that is, the terminal will detect PDCCH and SPS-PDSCH. Since the network side indicates that the cell DTX is activated, the shared channel scheduling of the new transmission will not be performed. Therefore, the terminal detection will not detect effective PDCCH scheduling, and will not cause additional performance impact on network performance. In addition, the terminal will also measure CSI-RS and report it. However, since the network has indicated that the cell DTX is activated, the network side will not receive CSI reports during the non-activation period, so it will not affect the scheduling on the network side. That is, in scenario 1, the missed detection of the activation information of the cell DTX will not affect data transmission.

[0111] Scenario 2

[0112] In scenario 2, the cell is currently in DTX activation state. Since the terminal still believes that the cell DTX is activated, the terminal will not detect PDCCH or SPS-PDSCH during the inactive period, and the network indicates that the cell DTX is deactivated. Therefore, even in the inactive phase determined by the cell DTX configuration, the network will resume normal data transmission, which will cause missed detection of data transmission and affect transmission performance. At the same time, in the cell DTX inactive phase, the terminal will not measure and report CSI-RS, so that the network side cannot obtain the corresponding information, which will affect the efficiency of data transmission.

[0113] Scene 3

[0114] In scenario 3, the terminal believes that the current cell DRX is in a deactivated state. Therefore, when entering the inactive period determined by the cell DRX configuration, the terminal will send SR, CG-PUSCH, and report periodic SRS and periodic CSI. However, the network side indicates that the cell DRX is activated, so the network will save energy during the inactive period determined by the DRX configuration and will not receive periodic data. In this case, not receiving periodic SRS and CSI will not be a big problem. However, for SR, since the network side does not respond, the terminal will trigger the physical random access channel (PRACH) after reaching the maximum number of times; similarly, for CG-PUSCH, since the network side does not respond, the terminal will not receive instructions for new transmissions and retransmissions, resulting in the terminal being unable to clear the cache in time.

[0115] Scene 4

[0116] When the cell DRX is not activated, the terminal will not perform periodic CSI reporting and SRS feedback, so the network side cannot obtain the corresponding channel related information. At the same time, the terminal will not send SR and CG-PUSCH, so there is no impact.

[0117] In actual application, for the above scenario 2, the terminal can perform enhanced processing when missed detection is found to reduce the impact on data transmission.

[0118] Based on this, in one embodiment, the method may further include:

[0119] For the at least one cell, when the cell DTX is activated, when the DCI is not detected at the monitoring opportunity of the DCI, perform at least one of the following operations:

[0120] Detect PDCCH in USS;

[0121] Detect PDCCH in type-3-CSS;

[0122] Receive periodic CSI-RS.

[0123] Here, in actual application, for each cell in the at least one cell, when the cell DTX is activated, if the terminal does not detect the DCI at the listening opportunity of the DCI, it can be determined that missed detection occurs, so the terminal can perform the above processing (which can be understood as enhanced processing). Specifically, the terminal can perform the above processing during the inactive period determined by the cell DTX configuration.

[0124] The terminal detects the PDCCH in the USS and / or detects the PDCCH in the type-3-CSS, which may be for the PDCCH scheduled for new transmission.

[0125] In actual application, for the detection of PDCCH in USS and / or detection of PDCCH in type-3-CSS, an effective time can be set, called the second effective time, that is, the time to start detection. The terminal can start PDCCH detection after the second effective time to ensure that the terminal can complete PDCCH processing or detection-related preparations; the second effective time can be configured by the network side (for example, through RRC signaling configuration) or can be pre-defined. The embodiment of the present application does not limit this. At the same time, the embodiment of the present application does not limit the specific value of the second effective time.

[0126] In addition, the terminal may also receive periodic CSI-RS to achieve channel measurement. This is because: in the related art, when the cell DTX is activated, the terminal will not receive periodic CSI-RS during the cell DTX inactivation period to achieve network energy saving. However, in the case of missed detection by the terminal, in order to avoid the network side deactivating the cell DTX and thus missing the channel measurement, the terminal may be configured to receive periodic CSI-RS.

[0127] In actual application, for the above scenario 3, the terminal can perform enhanced processing when missed detection is found.

[0128] Based on this, in one embodiment, the method may further include:

[0129] For the at least one cell, when the cell DRX is deactivated, when the DCI is not detected at the monitoring opportunity of the DCI, no SR and / or CG-PUSCH is sent during the inactivation period of the cell DRX.

[0130] Here, in actual application, for each cell in the at least one cell, if the terminal does not detect the DCI at the listening time of the DCI when the cell DRX is deactivated, it can be determined that a missed detection has occurred. Therefore, the terminal can perform enhanced processing; specifically, the terminal does not send SR and / or CG-PUSCH during the inactive period of the cell DRX until the next DCI is received, and determines whether to send SR according to the activation or deactivation status indicated by the next DCI, or determines whether to send CG-PUSCH, or determines whether to send SR and CG-PUSCH at the same time.

[0131] In actual application, for the non-transmission of SR and / or CG-PUSCH, an effective time can be set, which is called the third effective time, that is, the start time of non-transmission. During the non-activation period of DRX of the cell, the terminal can not send SR and / or CG-PUSCH after the third effective time. The third effective time can be configured by the network side, such as through RRC signaling configuration, or it can be pre-defined. The embodiment of the present application does not limit this. At the same time, the embodiment of the present application does not limit the specific value of the third effective time.

[0132] In summary, when it is determined that missed detection occurs, the terminal can perform enhanced processing on the sending behavior and / or the receiving behavior to avoid affecting the network performance, thereby improving the network transmission efficiency.

[0133] In actual application, the network side may configure the terminal whether to perform the above-mentioned enhanced processing. When the network side configures the terminal to perform the above-mentioned enhanced processing, when the terminal misses the DCI, the above-mentioned enhanced processing is performed. When the network side does not configure the terminal to perform the above-mentioned enhanced processing (it can also be understood as configuring not to perform the above-mentioned enhanced processing), when the terminal misses the DCI, the above-mentioned enhanced processing is not performed.

[0134] In actual application, the network side may also configure repeated transmission for the terminal to reduce the occurrence of missed detection, thereby enhancing the reliability of the PDCCH.

[0135] Based on this, in one embodiment, the method may further include:

[0136] The DCI is monitored in N time units, where N is an integer greater than or equal to 1; wherein when N is greater than 1, the DCI is repeatedly sent in N time units.

[0137] In actual application, the time unit may include a time slot, a subframe, an orthogonal frequency division multiplexing (OFDM) symbol, etc. The embodiment of the present application does not limit the type of the time unit.

[0138] In addition, the network side can configure the repetition transmission related information (such as the number of repetition transmissions (N) or the number of repetition time units) through the duration (English can be expressed as duration) parameter of the search space, and can also send special configuration information to the terminal to indicate the repetition transmission related information. As can be seen from the above description, N is configured by the network side.

[0139] In actual application, the network side may send the DCI in N time units. When N is greater than 1, the network side repeatedly sends the DCI in N time units. Accordingly, the terminal may monitor the DCI in N time units. In this way, the reliability of the PDCCH can be enhanced by N transmissions of the DCI.

[0140] It should be noted that, for repeated transmission, the terminal does not expect the DTX and / or DRX activation states of the cells indicated by the DCI sent in N time units to be different; that is, the terminal expects the DCI repeatedly sent by the network side in N time units to be the same, that is, the DTX and / or DRX activation states of the cells indicated by each DCI are the same.

[0141] Here, in actual application, the network side may also configure an effective time (also referred to as application time) for the terminal, so that the terminal can complete necessary data processing or preparation work within the effective time.

[0142] Specifically, in one embodiment, the activation or deactivation of the cell DTX and / or DRX indicated by the DCI takes effect after a first effective time, and the starting reference time of the first effective time includes the last time unit of N time units or the next time unit of the last time unit of N time units.

[0143] In actual application, the terminal can activate or deactivate the DTX and / or DRX of the cell indicated by the DCI after experiencing the first effective time, so as to provide the network side with an opportunity to retransmit the DCI; wherein, the terminal can start calculating the first effective time after the network side repeatedly sends the DCI in N time units, that is, after the terminal monitors the DCI in N time units, it activates or deactivates the DTX and / or DRX of the cell indicated by the DCI after experiencing the first effective time. In this way, the reliability of DCI detection can be improved and the occurrence of missed detection can be reduced.

[0144] Here, the first effective time of the DCI may be configured by the network side or may be predefined.

[0145] In the case where the first effective time is configured by the network side, the terminal can receive third information sent by the network side to determine the first effective time of the DCI; specifically, in one embodiment, the terminal receives third information, and the third information is used to indicate the first effective time of the DCI.

[0146] Here, in actual application, the first validity time may be configured through RRC signaling, etc. In this case, the terminal receives RRC signaling, and the RRC signaling includes the third information.

[0147] Accordingly, the embodiment of the present application also provides an information indication method, which is applied to a network device (such as a base station), such as Figure 5 As shown, the method includes:

[0148] Step 501: Send DCI to the terminal, where the DCI is used to indicate activation or deactivation of DTX and / or DRX of at least one cell; wherein the terminal is configured with the position of the DTX activation or deactivation bit of the cell and / or the DRX activation or deactivation bit in the DCI.

[0149] In one embodiment, if Figure 3 As shown, the method may also include:

[0150] Step 502: Send first information to the terminal, where the first information provides the position of the DTX activation or deactivation bit of the cell and / or the DRX activation or deactivation bit in the DCI.

[0151] In one embodiment, the method may further include:

[0152] Second information is sent to the terminal, where the second information is used to indicate that the DTX activation or deactivation bit of at least one cell among the at least one cell is the same as the DRX activation or deactivation bit.

[0153] In one embodiment, the method may further include:

[0154] The DCI is sent in N time units, where N is an integer greater than or equal to 1; when N is greater than 1, the DCI is repeatedly sent in N time units.

[0155] In one embodiment, the method may further include:

[0156] Sending third information to the terminal, the third information is used to indicate the first effective time of the DCI, and the starting reference time of the first effective time includes the last time unit of N time units or the next time unit of the last time unit of N time units.

The technical solution provided in the embodiment of the present application enables the terminal to obtain the activation status of the DRX and / or DTX of its own serving cell from the DCI through the position of the DTX and DRX activation or deactivation bits of the cell configured on the network side, thereby realizing the indication of the DRX and / or DTX activation or deactivation of the cell, and further realizing the RTX or DRX activation or deactivation of the cell.
