Description

Technical Field

[0001] This application relates to the field of communication technology, and in particular to a method and apparatus for transmitting and processing downlink control information. Background Technology

[0002] In new radio technology (NR) systems, when a user is in connected mode, the user needs to detect all the physical downlink control channel (PDCCH) monitoring opportunities configured in all time slots. However, in most PDCCH monitoring opportunities, the base station does not send PDCCH, so these PDCCH monitoring are unnecessary. The user needs to consume power to perform PDCCH monitoring, and these PDCCH monitoring will waste terminal energy.

[0003] In NR, statistics are provided for Connected Mode Discontinuous Reception (C-DRX) data of the Long Term Evolution (LTE) system. In most cases, there is no data during the LTE C-DRX period, as shown in Table 1 below.

[0004] Table 1 Statistical Analysis Based on Logarithmic Data of LTE C-DRX

[0005] application The proportion of DRX cycles without scheduling video stream 89％ audio stream 90％ Web browsing 71％

[0006] As shown in Table 1, in most cases, there is no data scheduling during DRX cycles. Users will perform PDCCH detection when DRX wireless is enabled. These DRX cycles can put users into deep sleep, and when users are in deep sleep, their power consumption is less than one percent of the power consumption of performing PDCCH detection.

[0007] Since the availability of data scheduling in each DRX cycle is dynamic, the base station cannot indicate whether there is data in each DRX cycle through higher-layer signaling. The base station can use the physical layer PDCCH or signals to indicate whether there is data in the DRX cycle. For each user, it is necessary to indicate whether the current DRX requires PDCCH detection. Carrying one bit of data on a PDCCH would waste PDCCH resources. Summary of the Invention

[0120] This application provides a method and apparatus for transmitting and processing downlink control information, which can notify the user group of energy-saving information through group-common downlink control information (DCI), thereby improving resource utilization and ensuring the flexibility of base station scheduling.

[0121] The method and apparatus are based on the same concept of the application. Since the methods and apparatus solve problems in similar ways, the implementation of the apparatus and methods can refer to each other, and the repeated parts will not be described again.

[0122] The technical solutions provided in this application can be applied to various systems, especially 5G systems. For example, applicable systems include Global System for Mobile Communication (GSM), Code Division Multiple Access (CDMA), Wideband Code Division Multiple Access (WCDMA) General Packet Radio Service (GPRS), Long Term Evolution (LTE), LTE Frequency Division Duplex (FDD), LTE Time Division Duplex (TDD), Universal Mobile Telecommunications System (UMTS), Worldwide Interoperability for Microwave Access (WiMAX), 5G systems, and 5G NR systems. All of these systems include terminal equipment and network equipment.

[0123] The terminal devices involved in the embodiments of this application can be devices that provide voice and / or data connectivity to users, handheld devices with wireless connectivity, or other processing devices connected to a wireless modem. The names of the terminal devices may differ in different systems; for example, in a 5G system, a terminal device can be called user equipment (UE). Wireless terminal devices can communicate with one or more core networks via the RAN. Wireless terminal devices can be mobile terminal devices, such as mobile phones (or "cellular" phones) and computers with mobile terminal devices, for example, portable, pocket-sized, handheld, computer-embedded, or vehicle-mounted mobile devices that exchange voice and / or data with the radio access network. Examples include personal communication service (PCS) phones, cordless phones, session initiated protocol (SIP) phones, wireless local loop (WLL) stations, personal digital assistants (PDAs), and other devices.

[0125] The various embodiments of this application will now be described in detail with reference to the accompanying drawings. It should be noted that the order in which the embodiments are presented in this application represents only a chronological order and does not represent the superiority or inferiority of the technical solutions provided by the embodiments.

[0126] This application provides a user group-based downlink control information that can instruct users in the user group to perform energy-saving information such as PDCCH detection in the corresponding DRX cycle. This downlink control information can be referred to as power-saving downlink control information (PS-DCI). The goal is to improve resource utilization while ensuring the flexibility of base station scheduling.

[0127] In the technical solution provided in this application embodiment, the base station configures a new group-common DCI and / or reuses an existing group-common DCI to indicate at least one power-saving information field of at least one terminal. The information field includes M user groups, where M is a positive integer greater than or equal to 1. Each user group contains N variable bits, meaning the number of bits in each information field is variable, and N is a positive integer greater than or equal to 1. The DCI format is scrambled using at least one newly defined Radio Network Temporary Identity (RNTI) and / or an existing RNTI. The reuse of the existing group-common DCI can be a slot format indication (SFI) group-common DCI. The SFI can reuse reserved bits and / or implicitly indicate power-saving information using D, U, or X types. Here, D represents downlink transmission; U represents uplink transmission; and X indicates that the transmission direction can be uplink or downlink.

[0128] Using the method described above, the base station can define a new DCI format and a new RNTI scrambling to indicate the terminal's energy-saving information configuration; or, it can use an existing RNTI, with the bit field of the energy-saving information carried in the existing DCI format, thereby enabling the UE to achieve energy saving.

[0129] The embodiments of this application are described below on both the base station side and the terminal side:

[0130] On the network side, see Figure 1 For example, on the base station side, an embodiment of this application provides a downlink control information transmission method, including:

[0131] S101. Determine the downlink control information (group-common DCI) shared by the user group, wherein the group-common DCI is used to indicate energy-saving information of at least one terminal;

[0132] In this application embodiment, a new group-common DCI is defined to indicate at least one power-saving information of at least one UE.

[0133] In the following text, group-common DCI can also be referred to as group-common PS-DCI, or simply as PS-DCI.

[0134] S102, Send the group-common DCI to the terminal.

[0135] This method determines the group-common DCI shared by user groups, which is used to indicate energy-saving information for at least one terminal; the group-common DCI is sent to the terminal, thereby improving resource utilization and ensuring the flexibility of base station scheduling.

[0136] Optionally, the energy-saving information includes one or a combination of the following:

[0137] Whether to wake up and monitor the physical downlink control channel (PDCCH);

[0138] Whether to monitor PDCCH during hibernation;

[0139] Whether to monitor F PDCCH time units; F is a positive integer greater than or equal to 1;

[0140] Whether to skip monitoring G PDCCH time units; G is a positive integer greater than or equal to 1;

[0141] Should the bandwidth portion of the BWP be switched?

[0142] Whether to activate or deactivate the carrier;

[0143] Should a dormant secondary cell be configured?

[0144] Configure the DRX parameter set;

[0145] Whether to configure PDCCH decoding power saving information;

[0146] Is the wireless resource management (RRM) power-saving function configured?

[0147] Whether to trigger the transmission of reference signals and / or the reporting of relevant measurement information.

[0148] Optionally, the energy-saving information can be configured separately for different users.

[0149] The user mentioned in the embodiments of this application may refer to a terminal, such as a user equipment (UE).

[0150] Optionally, the group-common DCI includes M users or user groups, where M is a positive integer greater than or equal to 1, and each user group contains N variable bits, where N is a positive integer greater than or equal to 1.

[0151] Optionally, the bit is used to identify energy-saving information of the UE or UE group during the time period corresponding to the bit. The time corresponding to the bit is determined according to standard specifications.

[0152] Optionally, the format of the group-common DCI is scrambled by at least one Radio Network Temporary Identifier (RNTI).

[0153] Optionally, the RNTI is a newly defined RNTI or a reused existing RNTI.

[0154] Optionally, the existing RNTI is a slot format indicator radio network temporary identifier (SFI-RNTI).

[0155] The SFI-RNTI indicates that the DCI carrying energy-saving information is the SFI-DCI;

[0156] The SFI-DCI is based on the SFI DCI reserved bit indication or on the SFI used bit indication.

[0157] The SFI-based bit indication indicates that when the SFI indication is X, it means that the user is in an energy-saving state in the corresponding time and frequency unit.

[0158] For example, the following steps are performed on the base station side:

[0159] Step 1: The base station determines the user group and obtains the scheduling information for each user in the DRX cycle within the user group;

[0160] The specific grouping and scheduling of users can be configured according to specific needs, and this application embodiment does not limit this.

[0161] Users in the same group can share a single group-common PS-DCI.

[0162] The DRX cycle and the start time of DRX wireless activation can be different or the same for different users in the same group.

[0163] Step 2: The base station configures the PDCCH parameters for each user's PS-DCI and / or the indication parameters carried by the PS-DCI. The indication parameters carried by the PS-DCI include specific PDCCH detection opportunities, which may refer to PDCCHs other than the PS-DCI, or all PDCCHs containing the PS-DCI, or one or more types of PDCCHs; or the search space and time-frequency resources of a specific PDCCH; and / or the group identifier of the PS-DCI, which may be represented by RNTI; and / or the bits and content corresponding to the user power saving domain.

[0164] Here, the user power saving domain can correspond to one bit in the DCI for each user, or multiple bits for each user. Each user corresponds to one or more information domains. Information domains can be shared by different users or only for one user; each user group contains N variable bits, where N is a positive integer greater than or equal to 1, and different users can have different N values. The meaning of each bit can be predefined by the standard, or the meaning indicated by each user's power saving bit can be configured through higher-layer signaling. The information domain can indicate whether the user is awake or asleep, and the configuration of frequency domain activation, time domain PDCCH detection, and spatial beam management related content after wake-up. The information domain can also be indicated using SFI; in NR, SFI indicates the time slot structure. This application embodiment uses SFI to indicate wake-up or sleep status, requiring minimal modification to the standard and achieving power saving.

[0165] Here, when the group identifier of the PS-DCI is represented by RNTI, it can be a newly defined RNTI and / or an existing RNTI scrambled.

[0166] Here, the PDCCH parameters carrying PS-DCI may include the configuration of PDCCH resources and monitoring opportunities carrying PS-DCI.

[0167] Step 3: The base station transmits PS-DCI on the PDCCH resource carrying PS-DCI.

[0168] Here, you can configure the PS-DCI transmission to begin when DRX radio is on, or at the end of DRX OFF, or periodically during DRX radio-on. However, when the user is in sleep mode, the user will not receive PS-DCI. Sleep mode here refers to DRX OFF, MAC CE indicating the user is asleep, the OnDuration counter reaching a set value causing the user to sleep, or the InActivity counter reaching a set value causing the user to sleep. DRX radio on is one state of DRX on; there are two DRX on states: DRX radio on and DRX on. First, enter DRX radio on state to turn on the wireless device, then enter the DRX on state to send and receive data.

[0169] PS-DCI can be transmitted during DRX radio-On or DRX off. If transmitted during DRX radio-On, it applies to the current DRX radio-On range; if transmitted during DRX off, it applies to the next DRX radio-On cycle. When PS-DCI is in DRX OFF, it indicates the PDCCH detection and / or sleep status, and / or measurement status for the next DRX radio on.

[0170] The information indicated by the PS-DCI may also include information indicating the time offset of the location where the PDCCH needs to be detected relative to the current PS-DCI location, but this method should not affect the start time of the OnDuration counter.

[0171] When a DRX wireless enable cycle contains multiple PS-DCI cycles, the OnDuration counter and InActivity counter should not be reset in each PS-DCI cycle.

[0172] PS-DCI can also include information to indicate the selection of PDCCH detection opportunities, specifically to further select PDCCH detection opportunities from the existing higher-layer configuration. A PDCCH detection opportunity refers to a user's ability to perform PDCCH detection only on that specific opportunity. This can be indicated through bit mapping, where each user / all users / some users have one or more dedicated bits indicating their power saving information; or by pre-setting a table listing various PDCCH detection opportunity patterns. The base station indicates the pattern's sequence number in the table to the terminal, allowing the terminal to determine the pattern corresponding to that number based on the pre-set table, thereby further determining the PDCCH detection opportunity to be selected.

[0173] Accordingly, on the terminal side, see Figure 2 This application provides a downlink control information processing method, including:

[0174] S201. Receive group-common DCI (Downlink Control Information) shared by the user group;

[0175] S202. Obtain energy-saving information from the group-common DCI and perform corresponding processing based on the energy-saving information.

[0177] Whether to wake up and monitor the physical downlink control channel (PDCCH);

[0178] Whether to monitor PDCCH during hibernation;

[0179] Whether to monitor F PDCCH time units; F is a positive integer greater than or equal to 1;

[0180] Whether to skip monitoring G PDCCH time units; G is a positive integer greater than or equal to 1;

[0181] Should the bandwidth portion of the BWP be switched?

[0186] Is the wireless resource management (RRM) power-saving function configured?

[0187] Whether to trigger the transmission of reference signals and / or the reporting of relevant measurement information.

[0188] In addition to the information mentioned above, energy-saving information can also be used to indicate other types of energy-saving information, which will not be elaborated on again.

[0189] Optionally, the group-common DCI includes M users or user groups, where M is a positive integer greater than or equal to 1, and each user group contains N bits, where N is a positive integer greater than or equal to 1.

[0190] Optionally, the bit is used to identify energy-saving information of the UE or UE group during the time period corresponding to the bit. The time corresponding to the bit is determined according to standard specifications.

[0191] Optionally, the format of the group-common DCI is scrambled using at least one wireless network temporary identifier (RNTI).

[0192] Optionally, the RNTI is a newly defined RNTI or a reused existing RNTI.

[0193] Optionally, the existing RNTI is a slot format indicator radio network temporary identifier (SFI-RNTI).

[0194] The SFI-RNTI indicates that the DCI carrying energy-saving information is the SFI-DCI;

[0195] The SFI-DCI is based on the SFI DCI reserved bit indication or on the SFI used bit indication.

[0196] For example, the terminal side performs the following steps:

[0197] Step 1: The terminal receives the PDCCH parameters of the PS-DCI configured by the base station. The terminal then receives and detects the PS-DCI according to the PDCCH parameters of the PS-DCI, and obtains the PDCCH detection opportunity, search space and time-frequency resources, and / or the group identification identifier of the PS-DCI, such as the corresponding RNTI, and / or the field corresponding bit of the user's PS-DCI, and / or the current scope of the PS-DCI.

[0198] Here, the scope of PS-DCI can be a high-level instruction, or PS-DCI can be applied in the non-sleep state during DRX On, or PS-DCI can be applied in the current PS-DCI cycle.

[0199] Step 2: The user determines whether PDCCH detection is needed in the corresponding scope based on the PS-DCI PDCCH parameters;

[0200] Here, when the DRX cycles of users in any group are different, if the PS-DCI is sent at the beginning of each DRX, each user only needs to receive the PS-DCI according to its own PS-DCI configuration and determine whether PDCCH detection is required based on the PS-DCI. If a user receives a PS-DCI instructing it not to perform PDCCH detection, then after receiving this PS-DCI, the user will not perform PS-DCI detection within the scope of its effect. Alternatively, if a user receives a PS-DCI instructing it to enter sleep mode, then the user will enter sleep mode after receiving this PS-DCI until the next DRX cycle. Or, if a user receives a PS-DCI instructing it to perform PDCCH detection, then the user will perform PDCCH detection according to the DRX timing after receiving this PS-DCI.

[0201] When PS-DCI is DRX OFF, it indicates the PDCCH detection and sleep status for the next DRX On.

[0202] Several specific implementation examples are given below.

[0203] Base station side:

[0204] Example 1: Define a new group-common DCI to indicate at least one power saving information for at least one UE.

[0205] Step 1: Configure user group information for the base station.

[0206] The base station is configured with at least one user group information, for example, configured with M user groups, where M is a positive integer greater than or equal to 1, and the user group information includes at least one UE;

[0207] The grouping of the at least one user group can be divided by the base station according to certain criteria, and can be at least one of the following: based on the UE's service characteristics, DRX parameter configuration, power saving configuration, QoS requirements, QCI, and other grouping methods, which are not limited in this document;

[0208] The DRX parameter configuration may include at least one of the following: DRX period, DRX OnDuration timer, DRX inactivity timer, and DRX offset; within a user group, at least one DRX parameter configuration is the same.

[0209] Optionally, the base station configuring user group information further includes: a bitmap for configuring user group information. The bitmap is used to indicate the trigger identifier for power-saving information of each UE within the current group. The number of users indicated by the bitmap and the number of user groups can be the same or different; specifically:

[0210] When the number of users indicated by the bitmap is equal to the number of user groups, each bit can be mapped to the energy-saving trigger information of a user group;

[0211] When the number of users indicated by the bitmap is greater than the number of user groups, each user group can be mapped to a bit in the bitmap, or multiple user groups can be mapped to a bit in the bitmap; the mapping relationship can be predetermined or semi-statically configured, for example, it can be configured through RRC signaling or MAC-CE.

[0212] The method for selecting one or more user groups can be predefined or semi-statically configured, for example, configured via RRC signaling or MAC-CE signaling.

[0213] Specifically, as shown in Table 2 below:

[0214] When the number of users indicated by the bitmap is less than the number of user groups, each bit in the bitmap can be mapped to energy-saving trigger information of one user group, or to energy-saving trigger information of multiple user groups. The mapping relationship can be predetermined or semi-statically configured, for example, through RRC signaling or MAC-CE configuration. When mapping to a user group, the method for selecting the user group can be predefined or semi-statically configured, for example, through RRC signaling or MAC-CE signaling configuration.

[0215] Table 2

[0216]

[0217] Step 2: The base station configures the parameters of the power-saving information field and / or PDCCH parameters of the PS-DCI bearer for each UE in each user group.

[0218] The PDCCH parameters may include at least one of the following: detection time-domain opportunity, CORESET resource configuration, search space resource configuration; PS-DCI group identifier, such as the corresponding RNTI; the number of bits in the DCI information field for each user; and the configuration of energy-saving information carried in the DCI information field for each user.

[0219] The parameters of the power saving information field of the PS-DCI may include at least one of the following: whether to wake up and monitor PDCCH, whether to sleep and not monitor PDCCH, whether to monitor F PDCCH time units, whether to skip monitoring G PDCCH time units, whether to switch BWP, whether to activate / deactivate carrier, whether to configure dormant secondary cell (Scell), whether to configure DRX parameter set, whether to configure PDCCH decoding power saving information, whether to configure Radio Resource Management (RRM) power saving function, and whether to trigger reference signal transmission and / or related measurement information reporting.

[0220] The configuration of the energy-saving information can be static, semi-static, or dynamic. The static or semi-static configuration can be configured using higher-level signaling, such as RRC signaling or MAC-CE configuration. The dynamic configuration can be based on DCI or MAC-CE configuration.

[0221] The PDCCH parameters can be predefined, configured by higher-layer signaling, for example, at least one of the following: RRC signaling, MAC-CE; can be static / semi-static configured; can be physical layer signal / signaling / channel configured, such as DCI configured; or can be dynamically configured.

[0222] The search space resource configuration can be configured as a common search space (CSS);

[0223] The RNTI may include at least one newly defined RNTI sequence, with each user group configured with a different RNTI sequence, and all UEs within each user group using the same RNTI sequence; the RNTI may reuse the RNTI of an existing group-common DCI, for example, it may be at least one of the following: SFI-RNTI, IT-RNTI, TPC-PUSCH-RNTI, TPC-PUCCH-RNTI, TPTC-SRS-RNTI.

[0224] The configuration refers to the number of bits in the DCI information fields of M user groups. Each user group can contain N variable bits greater than or equal to 1, where N is a positive integer not less than 1. The value of N can be configured by higher-layer signaling. Specifically, it can include at least one of the following: the base station configures the UE according to different QoS configurations, service characteristics, DRX parameter configurations, energy-saving configurations, quality of service (QoS) requirements, and quality of service class identifiers (QCI) for different groups. Other configuration methods are not limited in this document.

[0225] The N variable bits can indicate shared bit field information for all users in the group, or indicate energy-saving information for each user in the group. Specifically:

[0226] 1) Referring to Table 3 below, it can indicate that all UEs in this group share the same bit domain information. Taking the power saving information indication of PDCCH detection opportunity as an example, after receiving the power saving DCI indication, all UEs in the group uniformly configure the power saving information according to the content of the DCI indication. Specifically, taking PDCCH detection as an example.

[0227] It can be configured by the base station based on the number of detection opportunities for PDCCH monitoring between two group-common PS-DCIs, and / or it can be configured by the base station based on the number of detection opportunities for skipped PDCCH monitoring between two group-common PS-DCIs;

[0228] Each bit in N represents whether the UE performs PDCCH monitoring or skips PDCCH monitoring in the time unit corresponding to that bit.

[0229] The N can be equal to 1, representing the position of the detection opportunity between two group-common PS-DCIs, whether to detect PDCCH, and / or whether to skip PDCCH detection; or whether to activate PDCCH detection and / or deactivate PDCCH detection.

[0230] Table 3. Example of Bit Field Configuration

[0231]

[0232] 2) Referring to Table 4 below, the N variable bits can indicate the energy-saving information configuration of each UE in the group. The energy-saving information of each UE can be the same or different. The number of bits in the energy-saving information of each UE can be the same or different. Taking the energy-saving information indication PDCCH detection opportunity as an example, after receiving the energy-saving DCI indication, all UEs in the group uniformly configure the energy-saving information according to the content of the DCI indication. Specifically, taking the PDCCH detection opportunity as an example.

[0233] Table 4

[0234]

[0235] Based on the above, if the energy-saving information of each UE is different, but the number of bits in the energy-saving information of each UE is the same, the number of bits in the energy-saving information of each UE can be made the same by bit padding.

[0236] Step 3: The base station sends a DCI containing energy-saving information.

[0237] The PDCCH monitoring location of the DCI carrying energy-saving information is configured semi-statically by RRC, and can be transmitted at a uniform period or at a non-uniform period.

[0238] Example 2: Define an existing SFI group-common DCI to indicate at least one power saving information for at least one UE.

[0239] Step 1: Configure user group information for the base station.

[0240] Step 2: The base station configures the parameters of the power-saving information field and / or PDCCH parameters of the PS-DCI bearer for each UE in each user group.

[0241] PS-DCI may include at least one existing group-common DCI RNTI, for example, it may be at least one of the following: SFI-RNTI, IT-RNTI, TPC-PUSCH-RNTI, TPC-PUCCH-RNTI, TPTC-SRS-RNTI.

[0242] Taking SFI-RNTI as an example, SFI can be used to identify user group power-saving information. Specifically, in NR, PDCCH is used to indicate the time slot structure, see 38.211. When the symbol is X, the transmission direction of this symbol is flexible, and the user does not perform PDCCH reception and downlink measurement on this symbol. Group-based PS-DCI can also utilize this DCI format to configure symbols that do not require detection and / or measurement as flexible symbols. If the group common DCI is used to indicate power saving, when the user receives this PS-DCI, if the configured time slot structure does not contain downlink symbols, the user can enter sleep mode during the DRX On cycle, or simply not perform downlink PDCCH detection and / or measurement, or still perform uplink transmission and feedback according to the group common DCI indicating the time slot structure. The specific sleep mode or measurement or uplink transmission can be configured by higher layers.

[0243] PS-DCI and the DCI indicating the time slot structure can be configured separately or jointly. When PS-DCI and the DCI indicating the time slot structure are configured jointly, the user will have different processing behavior than if the DCI is configured to a specific time slot and / or a specific value. For example, if the DCI indicates that the time slot does not contain downlink symbols, the user can enter a sleep state during the DRX On period after receiving the signaling, or simply not perform downlink PDCCH detection, or still perform measurement, uplink transmission, and feedback according to the DCI indicating the time slot structure. The specific sleep state or measurement and uplink transmission can be configured through higher layers.

[0244] Each user has 8 bits indicating the slot structure, and 2 bits are unused. These 2 bits can indicate the activation status of the BandWidth Part (BWP) or the reduction of the PDCCH search space.

[0245] The PS-DCI and the DCI indicating the time slot structure can be configured uniformly. When the DCI is at a specific location, such as the beginning of DRX On or the end of DRX Off, the two unused bits can be used for a conventional purpose. (Otherwise, these two bits are ignored.)

[0246] Taking SFI-RNTI as an example, the two bits reserved in SFI can also be used to indicate the index to identify the energy-saving information of the user group. Specifically:

[0247] Taking index = 56~60 as an example, the indicated PDCCH detection location is shown in Table 5 below. Other index identifiers and the identifiers for monitoring PDCCH detection opportunities are not limited.

[0248] Table 5 Examples of SFI Information Field Indicators

[0249]

[0250] In Table 5 above, in SFI indexes 56 to 255, X and U can indicate skipping PDCCH monitoring, and D and X can indicate monitoring PDCCH; other indication methods will not be elaborated in this article.

[0251] Taking SFI-RNTI as an example, the bit field from index 0 to 55 in SFI can also be reinterpreted to identify the energy-saving information of user groups. Specifically:

[0252] The bit field is reinterpreted, and can be represented by X, U to indicate skipping PDCCH monitoring, and D, X to indicate PDCCH monitoring; other indication methods will not be elaborated in this article.

[0253] The base station can configure different interpretations of the SFI index by at least one of the following methods: configuring different SFI indexes on different SSs to distinguish the meaning of the SFI index; or configuring different SFI PDCCH detection opportunities to configure different SFI indexes. Other indication methods will not be elaborated here.

[0254] Step 3: The base station sends a DCI containing energy-saving information.

[0255] Terminal side:

[0256] Example 3: Define a new group-common DCI as at least one power saving information for at least one UE.

[0257] Step 1: UE obtains user group information.

[0258] Specifically, it is the same as step one in Example 1.

[0259] Step 2: The UE obtains the parameters of the power saving information field of PS-DCI and / or PDCCH parameters.

[0260] Specifically, the same as step two in Example 1;

[0261] Step 3: The UE receives the DCI carrying energy-saving information.

[0262] Specifically, it is the same as step three in Example 1.

[0263] Example 4: Define SFI group-common DCI to indicate at least one power saving information of at least one UE.

[0264] Step 1: UE obtains user group information.

[0265] Specifically, it is the same as step one in Example 2.

[0266] Step 2: The UE obtains the parameters of the power saving information field of PS-DCI and / or PDCCH parameters.

[0267] Specifically, the same as step two in Example 2;

[0268] Step 3: The UE receives the DCI carrying energy-saving information.

[0269] Specifically, it is the same as step three in Example 2.
