Terminals can switch between these two search space groups via explicit or implicit mechanisms to adaptively adjust their Physical Downlink Control Channel (PDCCH) listening, thereby achieving energy savings. Another energy-saving scheme involves obtaining relevant instructions to skip PDCCH listening, which means not listening to the PDCCH.

[0041] The following description, in conjunction with the accompanying drawings, details an energy-saving indication method, apparatus, device, and readable storage medium provided in this application through some embodiments and application scenarios.
[0042] See Figure 3 This application provides an energy-saving indication method, which is executed by a terminal, and the specific steps include: step 301 and step 302.
[0043] Step 301: Receive the first DCI, the first DCI including: a first indication;
[0044] Step 302: Determine the PDCCH monitoring behavior based on the first DCI;
[0045] The first instruction is used to instruct at least one of the following: switch to the target search space group and skip PDCCH listening.
[0046] It should be noted that skipping PDCCH listening in this article can mean not performing PDCCH listening, or skipping specific types of PDCCH listening.
[0047] For example, the first indication contains 1 bit, wherein when the 1 bit is a first value, it indicates switching to the target search space group; when the 1 bit is a second value, it indicates skipping PDCCH listening.
[0048] For example, the first indication contains 2 bits, wherein when the 2 bits are a third value, the indication switches to the target search space group; when the 2 bits are a fourth value, the indication skips PDCCH listening; and when the 2 bits are a fifth value, the indication switches to the target search space group and skips PDCCH listening.
[0049] For example, the first indication contains 1 bit, and the bit fields of this 1 bit are: '0' indicates switching to the target search space group, '1' indicates skipping PDCCH listening, or vice versa.
[0050] For example, the first indication contains 2 bits, where the value of these 2 bits can be "00", "01", "10", and "11". Three of these four values indicate switching to the target search space group and skipping PDCCH listening, and switching to the target search space group and skipping PDCCH listening, respectively. The remaining value is reserved or invalid. For example, the bit fields of these 2 bits are: '00' indicates switching to the target search space group, '01' indicates skipping PDCCH listening, '10' indicates switching to the target search space group and skipping PDCCH listening, and '11' is reserved or invalid.
[0051] It is understood that the above-mentioned 1 bit and 2 bits are only used to indicate the purpose of the first indication, not the specific content of the purpose. The specific content of the purpose can be indicated by other indication fields in the DCI, or by other signaling, such as RRC signaling.
[0052] Furthermore, after determining the purpose of the first instruction, the first instruction needs to specify the details of that purpose. For example, the first instruction may contain 1 bit to indicate switching to the target search space group, and 2 bits to indicate the specific index of the target search space group. As another example, the first instruction may contain 1 bit to indicate skipping PDCCH listening, and 2 bits to indicate how to skip PDCCH listening (including the type of PDCCH to skip or the duration of skipping PDCCH listening, etc.).
[0053] In this embodiment of the application, the first DCI further includes: a second indication, the second indication being used to indicate a first time interval (e.g., duration), and the terminal can determine PDCCH listening behavior within and / or after the first time interval based on the first DCI.
[0054] In this way, the terminal can determine the PDCCH listening behavior within the first time interval and / or the PDCCH listening behavior after the first time interval through the first DCI. That is to say, the network side can indicate the PDCCH listening behavior within the duration and / or after the duration to the terminal, realize flexible dynamic energy saving indication, and meet the diverse energy saving needs of the terminal.
[0055] In this embodiment of the application, before the step of receiving the first DCI, the method further includes: obtaining information of the first search space group and / or the second search space group;
[0056] Wherein, the first search space group is not associated with any search space or the first search space group is not configured with configuration information related to PDCCH listening, that is, PDCCH listening is not performed on the first search space group; the second search space group is used for PDCCH listening after the first time interval, that is, in some embodiments, after determining the PDCCH listening behavior within the first time interval according to the first DCI, PDCCH listening is performed through the second search space group after the first time interval.
[0057] It should be noted that the first search space group is a newly defined search space group in the embodiments of this application.
[0058] In a communication system, a network can be configured with multiple search space groups. For example, search space group 0 is characterized by a sparser PDCCH monitoring period; search space group 1 has a denser PDCCH monitoring period; and search space group 2 is not associated with any search space or the first search space group is not configured with any PDCCH monitoring-related information. A second search space group can be any of the aforementioned search space group 0, search space group 1, search space group 2, or any other search space group.
[0059] Optionally, the configuration information related to PDCCH monitoring may include one or more of the following: (1) search space index, (2) search space monitoring period, (3) search space duration, (4) control resource set (CORESET) index, and (5) CORESET duration.
[0060] Optionally, the first search space group and / or the second search space group are configured by the network side and / or agreed upon by the protocol.
[0061] For example, the network side is configured to search the first search space, and the protocol stipulates that after the first time interval, the PDCCH is monitored through the second search space group, and the second search space group is search space group 1.
[0062] In this embodiment of the application, the second search space group includes at least one of the following:
[0063] (1) Any search space group in the network configuration search space group;
[0064] It should be noted that any search space group in the network configuration search space group refers to the two search space groups mentioned above as defined in the existing protocol: search space group 0 and search space group 1. The PDCCH listening period of search space group 0 is either more frequent or less frequent than that of search space group 1.
[0065] (2) Default search space group;
[0066] It should be noted that configuring any search space group in the network configuration will set it as the default search space group.
[0067] (3) The first search space group;
[0068] (4) Current search space group.
[0069] It should be noted that the current search space group refers to the search space group used by the terminal before receiving the first DCI.
[0070] In this embodiment of the application, the PDCCH monitoring behavior within and / or after the first time interval is determined based on the first DCI, including any one of the following:
[0071] (1) When the first indication is used to indicate switching to the target search space group, the PDCCH is monitored through the target search space group during the first time interval;
[0072] (2) When the first indication is used to indicate switching to the target search space group, the PDCCH is monitored through the target search space group during the first time interval, and the PDCCH is monitored through the second search space group after the first time interval.
[0073] In this embodiment of the application, the PDCCH monitoring behavior within and / or after the first time interval is determined based on the first DCI, including any one of the following:
[0074] (1) If the first indication is used to indicate skipping PDCCH listening, skip the PDCCH listening within the first time interval;
[0075] (2) In the case where the first indication is used to indicate skipping PDCCH listening, skip PDCCH listening within the first time interval, and listen to PDCCH through the second search space group after the first time interval.
[0076] In this embodiment of the application, the PDCCH monitoring behavior within and / or after the first time interval is determined based on the first DCI, including any one of the following:
[0077] In the case where the first instruction is used to indicate switching to the target search space group and skipping PDCCH listening, PDCCH listening is skipped during the first time interval, and PDCCH is listened to through the target search space group after the first time interval;
[0078] In the case where the first instruction is used to indicate switching to the target search space group and skipping PDCCH listening, PDCCH listening is skipped during the first time interval, and PDCCH is listened to through the second search space group after the first time interval.
[0079] In the case where the first instruction is used to indicate switching to the target search space group and skipping PDCCH listening, PDCCH listening during the first time interval is skipped, and according to the protocol or the terminal's own choice between listening to PDCCH through the target search space group or listening to PDCCH through the second search space group after the first time interval, either through the target search space group or through the second search space group.
[0080] In one embodiment, when the first indication is used to indicate switching to the target search space group and skipping PDCCH monitoring, the terminal skips PDCCH monitoring during the first time interval and selects to monitor PDCCH through the target search space group after the first time interval. The selection method can be determined by a protocol specifying the application priority of the target search space group and the second search space group in this case. In this embodiment, the protocol specifies that the target search space group indicated in the first DCI has a higher priority.
[0081] In another embodiment of this application, when the first instruction is used to instruct switching to the target search space group and skipping PDCCH listening, the PDCCH listening behavior further includes: listening to the PDCCH through the target search space group during the first time interval, and skipping PDCCH listening after the first time interval.
[0082] It should be noted that the above four embodiments can be based on any of the following premises:
[0083] (1) The first DCI contains only the first indication;
[0084] (2) The first DCI includes a first instruction and a second instruction;
[0085] (3) The first DCI contains only the first indication and the network configuration and / or protocol agreed on the first search space group and / or the second search space group before receiving the first DCI;
[0086] (4) The first DCI contains a first instruction and a second instruction, and the network configuration and / or protocol agreed on a first search space group and / or a second search space group before receiving the first DCI.
[0087] In this embodiment of the application, the target search space group includes at least one of the following:
[0088] (1) Any search space group in the network configuration search space group;
[0089] (2) Default search space group;
[0090] (3) The first search space group.
[0091] For example, if the terminal receives the first DCI and the first indication is used to indicate switching to the target search space group, which is the first search space group, then the UE's behavior is to perform PDCCH listening according to the first search space group, that is, not to perform PDCCH listening.
[0092] In this embodiment of the application, the unit of the first time interval is any one of the following:
[0093] (1) Time slot;
[0094] (2) Symbol;
[0095] (3) Milliseconds (ms);
[0096] (4) The PDCCH monitoring period of the target search space group;
[0097] (5) The PDCCH listening cycle of the current search space group;
[0098] (6) Discontinuous Reception (DRX) cycle.
[0099] For example, if the first instruction is to skip PDCCH listening and the duration (first time interval) is 5, with the unit being the PDCCH listening cycle of the target search space group, then after the terminal receives the first DCI, it skips the PDCCH listening for a length of 5 target search space group PDCCH listening cycles.
[0100] In this embodiment of the application, the start time of the first time interval is at least one of the following:
[0101] (1) The effective time of the first instruction;
[0102] (2) The application time of the first indication;
[0103] (3) The start time of a specific time unit after receiving the first DCI.
[0104] It should be noted that receiving the first DCI means completing the reception of the first DCI. For example, if the first DCI lasts for 2 symbols, then receiving the first DCI is completed in the second symbol.
[0105] Optionally, the specific time unit can be the first slot, symbol, or ms. In another optional embodiment, the specific time unit can be M slots, M symbols, or M ms, where M is greater than or equal to 0.
[0106] In this embodiment of the application, the effective time of the first instruction is separated from the time after receiving the first DCI by an effective delay of the first instruction, or the application time of the first instruction is separated from the time after receiving the first DCI by an application delay of the first instruction.
[0107] In this embodiment, the network side can send a first DCI to the terminal, instructing the terminal to switch to the target search space group and / or skip PDCCH listening, thereby realizing flexible dynamic energy-saving instructions, clarifying the terminal's PDCCH listening behavior, and meeting the diverse energy-saving needs of the terminal.

[0109] Step 401: Send the first DCI, the first DCI including: a first indication, the first DCI being used by the terminal to determine PDCCH listening behavior;
[0110] The first instruction is used to instruct at least one of the following: switch to the target search space group and skip PDCCH listening.
[0111] In this embodiment of the application, the first indication includes 1 bit. When the 1 bit is a first value, it indicates switching to the target search space group. When the 1 bit is a second value, it indicates skipping PDCCH monitoring.

That is to say, the network side can indicate the PDCCH listening behavior within the duration and / or after the duration to the terminal, so as to realize flexible dynamic energy saving indication and meet the energy saving needs of the terminal.

[0141] Optionally, the specific time unit can be the first slot, symbol, or ms. In another optional embodiment, the specific time unit can be M slots, M symbols, or M ms, where M is greater than or equal to 0.
[0142] In this embodiment of the application, the effective time of the first instruction is separated from the time after receiving the first DCI by an effective delay of the first instruction, or the application time of the first instruction is separated from the time after receiving the first DCI by an application delay of the first instruction.
[0143] In this embodiment, the network side can send a first DCI to the terminal, instructing the terminal to switch to the target search space group and / or skip PDCCH monitoring, thereby achieving flexible dynamic power-saving instructions, clarifying the terminal's PDCCH monitoring behavior, and meeting the diverse power-saving needs of the terminal. The implementation methods of this application are described below with reference to Embodiments 1 and 2.
[0144] Example 1: See Figure 5 .
[0145] In this embodiment, the protocol stipulates that the PDCCH listening behavior after the first time interval is to switch to the default search space group to continue listening to the PDCCH;
[0146] Optionally, the network side is configured with a first search space group.
[0147] Optionally, the first search space group is not associated with any search space or is not configured with PDCCH monitoring information; that is, the UE does not perform PDCCH monitoring on the first search space group.
[0148] In this embodiment, the UE receives a first DCI, which includes a first indication and a second indication.
[0149] Optionally, the first indication is used to indicate switching to the first search space group, and the second indication is used to indicate that the first time interval can be 10ms, and the start time of the first time interval can be the effective time of the first indication.
[0150] In this embodiment, the UE can listen to the PDCCH using the first search space group within 10ms after the first instruction takes effect, based on the first instruction and the second instruction in the first DCI, and switch to the default search space group to continue listening to the PDCCH after 10ms.
[0151] According to Embodiment 1, the terminal dynamically determines the PDCCH listening behavior within a first time interval by receiving the first DCI, and determines the PDCCH listening behavior after the first time interval according to the protocol. This enables the terminal to flexibly perform PDCCH listening according to network instructions, dynamically adapt to the current service situation, and avoid the increase in terminal power consumption and data packet transmission latency caused by the excessive application latency and limited flexibility of the energy-saving instructions in the prior art.
[0152] Example 2: See Figure 6 .
[0153] In this embodiment, the protocol stipulates that the PDCCH listening behavior after the first time interval is to switch to the target search space group (that is, search space group 1) to listen to the PDCCH according to the instruction of the first instruction in the first DCI.
[0154] In this embodiment, the UE receives a first DCI, which includes a first indication and a second indication.
[0155] Optionally, the first instruction is used to indicate switching to search space group 1 and skipping PDCCH listening, for example, search space group 1 can be the search space group configured by the protocol;
[0156] Optionally, the second indication specifies a first time interval of 5, where the unit of the first time interval is the PDCCH monitoring period of search space group 1. The start time of this first time interval can be the effective time of the first indication.
[0157] In this embodiment, according to the first and second instructions in the first DCI, the UE skips PDCCH listening for a period of 5 search space group 1 after the first instruction takes effect, and switches to search space group 1 to continue listening to PDCCH after the PDCCH listening is skipped.
[0158] According to Embodiment 2, the terminal dynamically determines the PDCCH listening behavior within a first time interval and the PDCCH listening behavior after the first time interval by receiving the first DCI.
