Description

Technical Field

[0001] The present disclosure relates to the field of communication technology, and in particular to a method for indicating discontinuous transmission and related equipment. Background Art

[0002] The energy consumption of a single base station in a 5G (5th Generation Mobile Communication Technology) network can be more than three times that of LTE (Long Term Evolution).

[0055] Example embodiments will be described more fully hereinafter with reference to the accompanying drawings.

[0056] It should be noted that example embodiments may be implemented in many forms and should not be construed as being limited to the examples set forth herein.

[0057] The energy consumption of 5G networks is too high compared to 4G, which greatly affects the operating costs of 5G networks. Reducing the energy consumption of 5G networks is a common demand of global operators and equipment.

[0058] In order to save energy for terminals, both LTE and NR have introduced C-DRX (Discontinuous Reception) to keep the terminal in a dormant state for a long time to reduce energy consumption. 3GPP Rel-16 introduced the discontinuous reception (C-DRX) technology for terminals, which successfully reduced the energy consumption of terminals. Figure 1 As shown, in a short time slot before the start of the on-duration, the terminal needs to detect DCI (Downlink Control Information) format 2_6. The structure of DCI format 2_6 is as follows Figure 2As shown, each block includes a wake-up signal (WUS) and a cell dormancy indication (Scell ​​dormancy indication) to be detected by a terminal, wherein Block 1 includes the wake-up signal and the cell dormancy indication to be detected by UE 1 (terminal 1).

[0059] The inventors found that for the network side, the Cell DTX / DRX (cell discontinuous transmission / discontinuous reception) method can also be used to put the cell / base station to sleep, so that the energy consumption of the base station is greatly reduced. By putting the cell to sleep, the energy consumption of medium and low load networks can be further reduced, thereby reducing the operating cost of the NR network.

[0060] Using discontinuous transmission (including sending and receiving) of the base station to sleep can effectively reduce network energy consumption. In order to support discontinuous transmission of the base station, the base station needs to indicate that the terminal is activated / deactivated for discontinuous reception / transmission. This process can be completed by L1 signaling, that is, by the newly defined DCI format for corresponding indication.

[0061] Similarly, using discontinuous transmission (including sending and receiving) of the base station to sleep can effectively reduce network energy consumption. In order to support discontinuous transmission of the base station, the base station needs to indicate that the terminal is activated / deactivated for discontinuous reception / transmission. This process can be completed by L1 signaling, that is, by the newly defined DCI (downlink control signaling) format for corresponding indication.

[0062] Figure 3 A flow chart of a method for indicating discontinuous transmission in an embodiment of the present disclosure is shown. Figure 3 As shown, the discontinuous transmission indication method provided in the embodiment of the present disclosure includes steps S302-S304.

[0063] In S302, the base station sends an indication message to the terminal in the cell, where the indication message is used to indicate the discontinuous transmission state of the cell.

[0064] Here, the indication message includes a first indication; the first indication is used to indicate that the discontinuous transmission of the cell is in an activated state or an inactivated state. The discontinuous transmission of the cell includes discontinuous reception and / or discontinuous transmission of the cell.

[0065] In some embodiments, the indication message is transmitted to the terminal via downlink control information. The embodiment of the present disclosure redesigns the DCI format 2_6 mentioned above. The first indication in the present disclosure may be a DCI format or a DCI format 2_X, and is scrambled using a dedicated nes-RNTI.

[0066] It should be noted that the number of terminals in a cell can be one or more. Figure 4 As shown, base station 401 can send an indication message to terminal 402, terminal 403 and terminal 404. The terminals in the embodiments of the present disclosure include but are not limited to wireless communication devices such as mobile phones, tablet computers, notebooks, vehicle-mounted communication devices, and drones.

[0067] In S304, the terminal determines the discontinuous transmission state of the base station cell based on the first indication.

[0068] The cell discontinuous transmission includes the cell's discontinuous reception and / or discontinuous transmission (cell DRX / DTX), that is, the first indication is used to indicate that the cell's discontinuous reception (cell DRX) is in an activated state or an inactivated state, and to indicate that the cell's discontinuous transmission (cell DTX) is in an activated state or an inactivated state.

[0069] In some embodiments, the first indication includes a discontinuous reception indication bit (Cell-DRX-indication) and a discontinuous transmission indication bit (Cell-DTX-indication); the discontinuous reception indication bit is used to indicate that the discontinuous reception of the cell is in an activated state or an inactivated state, and the discontinuous transmission indication bit is used to indicate that the discontinuous transmission of the cell is in an activated state or an inactivated state.

[0070] As an example, when cell DTX / DRX is not activated, if it is detected that one of the discontinuous reception indication bit (Cell-DRX-indication) and the discontinuous transmission indication bit (Cell-DTX-indication) in the first indication is 1, it means that the corresponding feature is activated; when the feature is activated, similar to the mechanism of C-DRX, the indication message (DCI 2_X) defined in the present disclosure can be detected before the duration (onduration) of cell DRX / DTX, and if the corresponding indication value is 0, it indicates that the current cell DRX / DTX is terminated.

[0071] In some embodiments, the length of the first indication may be 2 bits, wherein the discontinuous reception indication bit is 1 bit and the discontinuous transmission indication bit is 1 bit.

[0072] It should be noted that the first indication in the embodiment of the present disclosure is effective for all terminals in the cell, so the discontinuous reception indication bit and the discontinuous transmission indication bit should be effective for users in the entire cell, and there is no need to define corresponding fields for different users. Figure 4 As shown, the first indication is effective to terminal 402 , terminal 403 , and terminal 404 .

[0073] The inventors have found that since there may be a conflict between the discontinuous transmission of a cell and the discontinuous reception of a terminal, this problem should also be considered when designing DCI.

[0074] Based on the above embodiment, it is considered that the terminal may activate C-DRX and cell DRX / DTX at the same time. Figure 5 As shown, there is a conflict between the C-DRX of the terminal and the cell-DTX / DRX of the cell, which will cause the terminal and the base station to be unable to receive each other's signals for a certain period of time, thereby affecting network performance.

[0075] In some embodiments, the indication message includes a plurality of control indication blocks for indicating each terminal in the cell respectively; each control indication block includes a second indication, and the second indication is used to indicate the clearing of the conflict between the cell discontinuous transmission and the terminal discontinuous reception. That is, for a terminal that has adopted C-DRX, the indication message in the present disclosure can be used to indicate that the cell discontinuous transmission / discontinuous reception (Cell DTX / DRX) is aligned with the terminal discontinuous reception (C-DRX).

[0076] exist Figure 4 In the scenario shown, the indication message may include three control indication blocks, which are used to indicate terminal 402, terminal 403 and terminal 404 respectively.

[0077] In some embodiments, the base station in the present disclosure also determines whether there is overlap between the active duration of the cell's discontinuous transmission and the terminal's discontinuous reception; when there is no overlap, the second indication is used to inform the terminal to adjust one or more of the following parameters of the terminal's discontinuous reception: active duration, sleep cycle, and sleep time offset.

[0078] In some embodiments, the number of control indication blocks of each terminal in the indication message is determined by high-layer signaling.

[0079] In some embodiments, the length of the second indication can be 1 bit, that is, a 1-bit terminal / base station discontinuous transmission alignment indication bit, CDRX-align-indication, is introduced in the DCI for each terminal. If this position is 1, the corresponding terminal will keep its C-DRX on-duration, sleep cycle, offset and other data consistent with the cell's Cell DTX / DRX to ensure that the base station and the terminal can receive information sent by each other during active time; if it is 0, no processing is required.

[0080] The embodiment of the present disclosure solves the conflict problem between cell discontinuous transmission and terminal discontinuous reception by introducing the second indication (alignment indication of each terminal).

[0081] When the terminal is configured with C-DRX and Cell-DTX / DRX at the same time, it is necessary to detect two types of RNTI (ps-RNTI and the newly defined nes-RNTI), that is, two DCI formats, at the same time, thereby increasing the complexity of PDCCH blind detection. Therefore, when the terminal is configured with Cell DTX / DRX and C-DRX at the same time, the information in DCI format2_6 can be transmitted simultaneously by multiplexing the indication message (DCI format2_X) in the present disclosure, thereby reducing the complexity of terminal PDCCH blind detection. At this time, nes-RNTI scrambling is still used. That is to say, in some embodiments, the indication message is also used to indicate the discontinuous reception of the terminal.

[0082] In some embodiments, after the second indication is sent once, the second indication is multiplexed to indicate whether the terminal discontinuous reception state of the terminal is awakened, and awakening means whether the terminal can receive signals within the next active duration of the discontinuous reception.

[0083] In some embodiments, a 1-bit wake-up signal (WUS) is added to each terminal in the indication message (DCI format2_X) of the present disclosure to indicate whether its C-DRX skips the next duration (on duration). This bit can be multiplexed with the second indication bit in the above embodiment, or 1 bit can be used alone.

[0084] In some embodiments, each control indication block of the indication message also includes a third indication; the third indication is used to indicate whether the terminal discontinuous reception state of the terminal is awakened, and awakening means whether the terminal can receive the signal within the next active duration of the discontinuous reception.

[0085] The disclosed embodiment can reuse the defined indication message (DCI format2_X) to transmit the information of DCI format2_6, thereby reducing the complexity of terminal blind detection.

[0086] In some embodiments, each control indication block of the indication message may further include a fourth indication; the fourth indication is used to indicate the sleep status of the secondary cell of the affected terminal.

[0087] In some embodiments, the length of the fourth indication in the control indication block is configured by higher layer signaling.

[0088] In some embodiments, the length of the fourth indication in the control indication block is in the form of a bitmap, and each bit is associated with a secondary cell of the terminal to indicate whether it is dormant.

[0089] In the indication message (DCI format2_X) disclosed in the present invention, a 0-5 bit fourth indication is added for each terminal, and the fourth indication is the secondary cell dormancy signal (Scell ​​dormancy) of the terminal, which is used to indicate the dormancy status of its secondary cell, wherein each bit is respectively associated with a secondary cell of the terminal, that is, when the fourth indication is 0 bit, there is no fourth indication; when the fourth indication is 1 bit, it is used to indicate the dormancy status of a secondary cell; when the fourth indication is 2 bits, each bit is respectively associated with the dormancy status of a secondary cell, and a total of 2 secondary cells are associated with the dormancy status.

[0090] Whether the indication message (DCI format2_X) disclosed in the present invention includes the indication value in the above embodiment and the specific number of bits of the fourth indication is similar to the configuration method of DCI format2_6, and is configured in the RRC parameters.

[0091] Figure 6 A structure of the indication message (DCI format2_X) disclosed in the present invention is shown, such as Figure 6 As shown, the indication message includes a first indication and N control indication blocks, and each control indication block includes a second indication and a fourth indication.

[0092] It should be noted that Figure 6 The order of the indication bits of the first indication, the second indication and the fourth indication can be adjusted. The number of control indication blocks (ie the number of indicated UEs) is configured by RRC parameters.

[0093] The disclosed embodiment indicates the activation / deactivation of discontinuous reception / transmission of a cell, solving the conflict problem between discontinuous transmission of a cell and discontinuous reception of a terminal. The newly introduced indication message (DCI format 2_X) keeps the same structure as 2_6 as much as possible, reducing the complexity of the terminal blind detection of the new PDCCH format.

[0094] Based on the same inventive concept, the embodiment of the present disclosure also provides a method for indicating discontinuous transmission, which is applied to a base station, such as Figure 7 As shown, the method includes step S702.

[0095] In S702, an indication message is sent to a terminal in the cell, where the indication message is used to indicate a discontinuous transmission state of the cell;

[0096] The indication message includes a first indication; the first indication is used to indicate that the discontinuous transmission of the cell is in an activated state or an inactivated state; the discontinuous transmission of the cell includes discontinuous reception and / or discontinuous transmission of the cell.

[0097] In the embodiment of the present disclosure, the base station can inform the terminal of the discontinuous transmission state of the cell by sending an indication message to the terminal in the cell.

[0098] Based on the same inventive concept, the embodiment of the present disclosure also provides a method for indicating discontinuous transmission, which is applied to a terminal, such as Figure 8 As shown, the method includes steps S802-S804.

[0099] In S802, an indication message sent by a base station is received, where the indication message is used to indicate a discontinuous transmission state of a cell; the indication message includes a first indication; the first indication is used to indicate that the discontinuous transmission of the cell is in an activated state or an inactivated state; the discontinuous transmission of the cell includes discontinuous reception and / or discontinuous transmission of the cell;

[0100] In S804, based on the first indication, the discontinuous transmission state of the base station cell is determined.

[0101] In the embodiment of the present disclosure, the terminal can obtain the discontinuous transmission state of the cell from the indication message sent by the base station.

[0102] In a specific example, discontinuous reception and discontinuous transmission of the cell are simultaneously enabled for terminals in the cell.

[0103] Assume that there are 3 terminals in the cell, such as Figure 4 As shown, the terminals 402 and 403 have started discontinuous reception, while the terminal 404 is still transmitting normally; the terminals 402 and 404 support cell discontinuous transmission, while the terminal 403 does not support cell discontinuous transmission. None of the three terminals involve Scell ​​dormancy.

[0104] When the cell is ready to start discontinuous transmission, it can send Fig. 9 In the indication message shown, the first indication 901 is effective for the terminal 402, the terminal 403 and the terminal 404, the control indication block 902 is effective for the terminal 402, and the control indication block 903 is effective for the terminal 404.

[0105] In this indication message, since only the terminal 402 and the terminal 404 can support cell DTX, there is no need to provide an indication for the terminal 403; since Scell ​​dormancy is not involved, the fourth indication message in the indication message, ie, the SCell dormancy indication bit, is not set.

[0106] After each terminal receives this indication message, since terminal 402 supports both C-DRX and Cell DTX, it needs to align the on duration, period, and timing offset of C-DRX with Cell DTX; terminal 403 does not support Cell-DTX, so there is no need to align C-DRX with Cell DTX, but the C-DRX of terminal 403 should be adjusted through RRC to avoid missing data; for terminal 404, it is only necessary to activate Cell DTX according to the RRC configuration of Cell DTX.

[0107] In the embodiments of the present disclosure, the terms “first”, “second” and “third” are used for descriptive purposes only and should not be understood as indicating or implying relative importance.

[0108] The term "and / or" in this disclosure is only a description of the association relationship of associated objects, indicating that there may be three relationships. For example, A and / or B can represent: A exists alone, A and B exist at the same time, and B exists alone. In addition, the character " / " in this article generally indicates that the associated objects before and after are in an "or" relationship.

[0109] Furthermore, although the steps of the method in the present disclosure are described in a particular order in the drawings, this does not require or imply that the steps must be performed in this particular order or that all the steps shown must be performed to achieve the desired results.

[0110] In some embodiments, certain steps may be omitted, multiple steps may be combined into one step, and / or one step may be decomposed into multiple steps.

[0111] Based on the same inventive concept, the embodiment of the present disclosure also provides a base station, such as Fig.10 As shown, the base station 1000 includes a message sending module 1002 .

[0112] The message sending module 1002 is used to send an indication message to a terminal in a cell, where the indication message is used to indicate the discontinuous transmission state of the cell; the indication message includes a first indication; the first indication is used to indicate that the discontinuous transmission of the cell is in an activated state or an inactivated state; the discontinuous transmission of the cell includes discontinuous reception and / or discontinuous transmission of the cell.

[0113] In some embodiments, the indication message is also used to indicate discontinuous reception of the terminal.

[0114] In some embodiments, the indication message includes a plurality of control indication blocks for respectively indicating each terminal in the cell; each control indication block includes a second indication, and the second indication is used to indicate clearing of conflict between discontinuous transmission of the cell and discontinuous reception of the terminal.

[0115] In some embodiments, after the second indication is sent once, the second indication is multiplexed to indicate whether the terminal discontinuous reception state of the terminal is awakened, and awakening means whether the terminal can receive signals within the next active duration of the discontinuous reception.

[0116] In some embodiments, each control indication block of the indication message also includes a third indication; the third indication is used to indicate whether the terminal discontinuous reception state of the terminal is awakened, and awakening means whether the terminal can receive the signal within the next active duration of the discontinuous reception.

[0117] In some embodiments, the number of control indication blocks of each terminal in the indication message is determined by high-layer signaling.

[0118] In some embodiments, the base station 1000 also includes a judgment module for determining whether there is overlap between the active duration of the cell's discontinuous transmission and the terminal's discontinuous reception; when there is no overlap, a second indication is used to inform the terminal to adjust one or more of the following parameters of the terminal's discontinuous reception: active duration, sleep cycle, and sleep time offset.

[0119] In some embodiments, each control indication block of the indication message further includes a fourth indication; the fourth indication is used to indicate the sleep status of the secondary cell of the affected terminal.

[0120] In some embodiments, the length of the fourth indication in the control indication block is configured by higher layer signaling.

[0121] In some embodiments, the length of the fourth indication in the control indication block is in the form of a bitmap, and each bit is associated with a secondary cell of the terminal to indicate whether it is dormant.
