Description

Technical Field

[0001] This invention relates to the field of wireless communication technology, and in particular to a method for indicating skipping downlink control information, a user equipment, and a readable storage medium. Background Technology

[0002] Battery life of user equipment (UE) is a crucial aspect of user experience, impacting the user experience of 5G terminals and / or services. To address this, 5G systems have introduced a feature to skip a portion of the Physical Downlink Control Channel (PDCCH) monitoring (PDCCH skipping).

[0003] In the research of 5G New Radio (NR) Release 17, techniques to reduce PDCCH snooping will be one of the key topics of discussion. For PDCCH skipping, the base station can send a PDCCH skipping indication to allow a connected UE to skip PDCCH snooping for a certain period. Typically, the base station sends the PDCCH skipping indication via Downlink Control Information (DCI).

[0004] In carrier aggregation, a UE has multiple serving cells, one of which is the primary cell (PCell) and the others are secondary cells (SCells). A UE can be configured with up to two DRX sets: a Legacy DRX and a Secondary DRX. Different serving cells belong to different DRX groups. For example, based on frequency band, the serving cell for FR1 (low-frequency serving cell) uses the Legacy DRX; the serving cell for FR2 (millimeter-wave band) uses the Secondary DRX.

[0005] However, in the existing technology, when the UE receives the PDCCH skipping DCI, it cannot know whether the skipping DCI will be applied to the Legacy DRX or the Secondary DRX, which may cause the UE to skip the DCI detection incorrectly, and the base station will not be able to schedule the UE smoothly.

[0031] When a UE receives a PDCCH Skipping DCI, the question of whether the UE should apply the Skipping DCI to the Legacy DRX or the Secondary DRX needs to be addressed. Otherwise, the UE may incorrectly skip the DCI detection, causing the base station to be unable to successfully schedule the UE.

[0032] In this embodiment of the invention, if a secondary DRX is configured, after receiving the skipping downlink control information, it is determined that the skipping downlink control information applies to the first serving cell in the legacy DRX group and the second serving cell in the secondary DRX group, so that the user equipment can know that the received skipping downlink control information applies to the first serving cell and the second serving cell.

[0033] To make the above-mentioned objectives, features and beneficial effects of the present invention more apparent and understandable, specific embodiments of the present invention will be described in detail below with reference to the accompanying drawings.

[0034] This invention provides a method for indicating skipping downlink control information, referring to... Figure 1 The following will provide a detailed explanation through specific steps.

[0035] Step S101: Receive skipping downlink control information.

[0036] Step S102: If a secondary DRX is detected to be configured, it is determined that the skipping downlink control information applies to the first serving cell in the legacy DRX group and the second serving cell in the secondary DRX group.

[0037] In practical applications, it is known that when a user equipment (UE) is in Radio Resource Control (RRC) connected state in the serving cell, it can establish one or more services. Typically, the serving cell can configure the search space and detection timing for PDCCH detection for the UE.

[0038] In practice, to reduce the power consumption of user equipment or its own load, the base station can send a skipping DCI to the user equipment, causing the user equipment to stop listening to the PDCCH. When the user equipment receives the skipping DCI in time slot n, it knows that it will skip PDCCH listening for a period of time. The period of skipping can be indicated by the skipping DCI, or the base station can configure the skipping duration in advance through higher-layer signaling such as RRC.

[0039] In practical applications, it is known that different serving cells belong to different DRX groups. For example, they can be divided according to frequency bands. FR1 (low-frequency band, typically below 6GHz) serving cells use legacy DRX, while FR2 (millimeter-wave band) serving cells use secondary DRX. In one embodiment of this invention, the base station configures five serving cells for the user equipment: PCell, SCell1, and SCell2 belong to FR1 and use legacy DRX; these three serving cells are called the legacy DRX group. SCell3 and SCell4 belong to FR2 and use secondary DRX; these two serving cells are called the secondary DRX group. In NR, in Release 15, the UE can only configure one DRX set. Release 16 introduced a second DRX set. The DRX set introduced in Release 15 is usually called Legacy DRX, and the DRX introduced in Release 16 is called secondary DRX. It should be noted that Legacy DRX and secondary DRX can also be represented in other ways, such as referring to Legacy DRX and secondary DRX as the first DRX set and the second DRX set, respectively.

[0040] In practice, the user equipment (UE) is configured with two DRX sets: one as a secondary DRX and the other as a legacy DRX. When the UE receives a skipping DCI, if it detects that a secondary DRX is configured, the received skipping DCI applies to the first serving cell within the legacy DRX group and the second serving cell within the secondary DRX group. As in the example above, the first serving cells include PCell, SCell1, and SCell2, and the second serving cells include SCell3 and SCell4. In this case, according to the skipping DCI instruction, the UE does not need to detect PDCCH on these serving cells in the next time period, i.e., it does not need to detect DCI.

[0041] It should be noted that, in this embodiment of the invention, at least one of the second serving cells within the secondary DRX group is active before the user equipment will use the received skipping DCI for the active serving cell in the second serving cell; if all the second serving cells corresponding to the secondary DRX group are inactive, the skipping DCI does not need to be applied to the second serving cells within the secondary DRX group.

[0042] Skipping DCI applies to the first serving cell, with the start time of skipping DCI detection being the first start time and the duration of skipping DCI detection being the first duration; meanwhile, skipping DCI applies to the second serving cell, with the start time of skipping DCI detection being the second start time and the duration of skipping DCI detection being the second duration.

[0043] In one embodiment of the present invention, the first start time is the same as the second start time, and the first duration is equal to the second duration. Both the first start time and the second start time begin from the time slot in which the skipping DCI is received.

[0044] In other words, if the user equipment detects that a secondary DRX is configured, after receiving the skipping DCI, it can determine that the skipping DCI applies to both the first serving cell and the second serving cell. The start time of the user equipment performing the skipping DCI detection in the first serving cell is the same as the start time of the user equipment performing the skipping DCI detection in the second serving cell, and the duration of the user equipment performing the skipping DCI detection in the first serving cell is equal to the duration of the user equipment performing the skipping DCI detection in the second serving cell.

[0045] For example, in both the first and second serving cells, the user equipment does not detect DCI for five consecutive time slots, starting from the time slot in which the skipping DCI is received.

[0046] In another embodiment of the present invention, the first start time is the same as the second start time, but the first duration is different from the second duration. Both the first start time and the second start time begin from the time slot when the skipping DCI is received.

[0047] In practice, the first duration can be related to the subcarrier spacing corresponding to the first serving cell. Correspondingly, the second duration can be related to the subcarrier spacing corresponding to the second serving cell.

[0048] For example, the first serving cells in the legacy DRX group all use a 15kHz subcarrier space (SCS), while the second serving cells in the secondary DRX group all use a 120kHz subcarrier space. Assuming the skipping DCI indicates a duration of 5 time slots, the durations of the 5 time slots in the legacy DRX group are not equal to the durations of the 5 time slots in the secondary DRX group.

[0049] In other words, for the first serving cell in the legacy DRX group and the second serving cell in the secondary DRX group, the base station can be configured with different skipping DCI detection durations.

[0050] As can be seen, in this embodiment of the invention, if a secondary DRX is configured, after receiving the skipping downlink control information, it is determined that the skipping downlink control information applies to the first serving cell in the legacy DRX group and the second serving cell in the secondary DRX group, so that the user equipment can know that the received skipping downlink control information applies to the first serving cell and the second serving cell.

[0051] It should be noted that if multiple DRXs can be configured for the UE in the NR, such as in the embodiments of the present invention, where each serving cell can have its own specific DRX, the method described in this embodiment is also applicable.

[0052] This invention also provides another method for indicating skipping downlink control information, referring to... Figure 2 The following will provide a detailed explanation through specific steps.

[0053] Step S201: Receive skipping downlink control information.

[0054] In practical implementation, the base station can set two independent information elements in the skipping DCI. The first information element is used to indicate PDCCH skipping of the first serving cell in the legacy DRX group (i.e., the user equipment does not need to detect PDCCH on the first serving cell), and the second information element is used to indicate PDCCH skipping of the second serving cell in the secondary DRX group (i.e., the user equipment does not need to detect PDCCH on the second serving cell). The first information element can correspond to one or more bits, and the second information element can also correspond to one or more bits.

[0055] In practice, skipping DCI can use existing DCI formats or introduce new DCI formats.

[0056] The network side can configure the position of the first cell and the position of the second cell in the skipping DCI, and the positions of the first cell and the second cell are different.

[0057] For example, the skipping DCI configured on the network side transmits a total of 10 bits of information, where the 4th bit is the cell location corresponding to the first DRX group, applicable to the first serving cell; and the 5th bit is the cell location corresponding to the second DRX group, applicable to the second serving cell.

[0058] Step S202: Obtain the first information cell and the second information cell from the skipping downlink control information.

[0059] Step S203: Based on the first information cell and the second information cell, determine the PDCCH skipping of the first serving cell and the PDCCH skipping of the second serving cell, respectively.

[0060] In practice, after receiving the skipping downlink control information, the user equipment can read the first cell and the second cell from the corresponding position.

[0061] Based on the above example, after receiving the skipping DCI, the user equipment can read the information in the 4th bit to know the PDCCH skipping corresponding to the first serving cell; and read the information in the 5th bit to know the PDCCH skipping corresponding to the second serving cell.

[0062] Therefore, the skipping downlink control information carries a first information element and a second information element. The first information element indicates the PDCCH skipping of the first serving cell (i.e., the user equipment skipping the DCI monitor on the first serving cell), and the second information element indicates the PDCCH skipping of the second serving cell (i.e., the user equipment skipping the DCI monitor on the first serving cell). After receiving the skipping downlink control information, the user equipment can obtain the first and second information elements from it to clearly know the PDCCH skipping corresponding to the first serving cell and the PDCCH skipping corresponding to the second serving cell.

[0063] It should be noted that if multiple DRXs can be configured for user equipment in NR, as in the embodiments of the present invention, each serving cell can have its own specific DRX. The embodiments of the present invention are also applicable. Different information elements in skipping DCI correspond to skipping DCI monitors on serving cells corresponding to different DRX groups, or correspond to skipping DCI monitors on different serving cells.

[0064] This invention also provides another method for skipping downlink control information, referring to... Figure 3 The following will provide a detailed explanation through specific steps.

[0065] Step S301: Detect the first search space and the second search space.

[0066] Step S302: Obtain first skipping downlink control information from the first search space, and obtain second skipping downlink control information from the second search space.

[0067] In specific implementations, the base station can configure different search spaces for the first skipping downlink control information and the second skipping downlink control information. In this embodiment of the invention, the base station can configure the first skipping downlink control information to be transmitted through search space 1, and the second skipping downlink control information to be transmitted through search space 2. The first skipping downlink control information is applied to the first serving cell within the legacy DRX group, and the second skipping downlink control information is applied to the second serving cell within the secondary DRX group, and the first search space and the second search space are different.

[0068] The user equipment can detect the first search space and the second search space respectively, obtain the first skipping downlink control information from the first search space, and obtain the second skipping downlink control information from the second search space.

[0069] Step S303: Obtain the PDCCH skipping corresponding to the first serving cell based on the first skipping downlink control information; obtain the PDCCH skipping corresponding to the second serving cell based on the second skipping downlink control information.

[0070] In specific implementation, the user equipment can obtain the PDCCH skipping corresponding to the first serving cell from the first skipping downlink control information (i.e., the user equipment skips the DCI monitor on the first serving cell), and obtain the PDCCH skipping corresponding to the second serving cell from the second skipping downlink control information (i.e., the user equipment skips the DCI monitor on the second serving cell).

[0071] In specific implementation, the first skipping downlink control information can be located in the primary serving cell (PCell) or the first serving cell, and the second skipping downlink control information can be located in the primary serving cell, the second serving cell, or the scheduling cell that schedules the second serving cell.

[0072] Therefore, it can be seen that by transmitting corresponding skipping downlink control information through different search spaces, different skipping downlink control information corresponds to different serving cells. The user equipment can determine whether the skipping downlink control information applies to the first or second serving cell by obtaining the corresponding skipping downlink control information in the search space. This embodiment of the invention uses different DCIs to indicate PDCCH skipping. Transmitting different DCIs through different search spaces has the advantage of simple design. Other solutions can be used to implement different DCIs indicating PDCCH skipping, such as using the same search space but employing different radio network temporary identifiers to scramble different DCIs, which can also achieve different DCIs indicating PDCCH skipping for different DRX groups.
