Description

Method, device and communication system for receiving and sending indication information Technical Field

[0001] The embodiments of the present application relate to the field of communication technologies. Background Art

[0002] As a crucial component of global new infrastructure development, 5G (fifth generation) communication networks have experienced rapid global development in recent years. As network scale continues to grow, operators' energy consumption continues to rise. According to data released by China's Ministry of Industry and Information Technology, energy consumption is projected to increase by approximately 80% between 2015 and 2022. With the deployment of 5G and the widespread commercialization of 5G active antenna units (AAUs), energy consumption is expected to increase exponentially compared to the remote radio units (RRUs) used in 3G and 4G, due to their higher power consumption. 5G defines three major service types: enhanced mobile broadband (eMBB), massive machine type of communication (mMTC), and ultra-reliable low latency communication (URLLC). This will lead to an increase in bursty small packet traffic and 24 / 7 base station operation. The average daily energy consumption of 5G sites is expected to be more than double that of 4G.

[0003] The 3rd Generation Partnership Project (3GPP) has introduced key technologies such as Massive MIMO and increased RF bandwidth in the 5G era. 5G supports higher data rates and greater data traffic, requiring more transmission bandwidth. High-frequency bands will be the primary frequency band for future 5G expansion. However, the transmission characteristics of high-frequency bands limit site coverage, leading to denser deployment of 5G sites. The increased energy consumption will also place significant pressure on operators' operating costs. Therefore, network energy conservation is crucial for reducing operating costs, and energy conservation in 5G networks is a pressing issue.

[0004] It should be noted that the above introduction to the technical background is merely intended to provide a clear and complete description of the technical solutions of this application and facilitate understanding by those skilled in the art. Simply because these solutions are described in the background technology section of this application, it should not be assumed that the above technical solutions are well known to those skilled in the art.

[0005] Summary of the Invention

[0006] To achieve energy conservation, network equipment can perform energy conservation processing in at least one of the time domain, frequency domain, spatial domain, and energy domain, respectively, based on the network load. For example, in the time domain, network equipment can introduce cell discontinuous transmission / reception (DTX / DRX) technology. By setting the cell active period (active period) and inactive period (non-active period or inactive period) in the network equipment, the network equipment only transmits and receives signals during the active period, and limits the transmission and reception of signals during the inactive period, thereby achieving the purpose of network energy conservation. In addition, network equipment can also introduce cell dormancy or cell shutdown technology to achieve energy conservation by stopping the transmission and reception of all signals.

[0007] The inventors of the present application have discovered that how to flexibly and efficiently notify terminal devices of information related to network energy saving has become a key issue that needs to be solved.

[0008] In response to at least one of the above-mentioned problems or other similar problems, an embodiment of the present application provides a method, apparatus and communication system for receiving and sending indication information. In the indication information receiving method, a terminal device receives first downlink control information (DCI) related to network energy saving from a network device, thereby enabling the terminal device to be flexibly and efficiently notified of information related to network energy saving.

[0009] According to one aspect of an embodiment of the present application, there is provided an apparatus for receiving indication information, applied to a terminal device, the apparatus including a first processor, the first processor controlling the terminal device to perform the following operations:

[0010] receiving a first configuration from a network device, wherein the first configuration is used to configure conditional switching;

[0011] receiving, in a first serving cell, first downlink control information (DCI) from the network device, where the first DCI includes first information and / or second information, where the first information is used to indicate dormancy or shutdown information related to A serving cells of the terminal device, and the second information is used to activate or deactivate cell discontinuous transmission or reception (Cell DTX / DRX) of B serving cells of the terminal device, where A and B are positive integers; and

[0012] The terminal device performs operations related to the conditional switching.

[0013] According to another aspect of an embodiment of the present application, there is provided an apparatus for sending indication information, which is applied to a network device. The apparatus includes a second processor, which controls the network device to perform the following operations:

[0014] Sending a first configuration to the terminal device, where the first configuration is used to configure conditional switching;

[0016] One of the beneficial effects of the embodiments of the present application is that the terminal device receives the first downlink control information (DCI) related to network energy saving from the network device, thereby being able to flexibly and efficiently notify the terminal device of information related to network energy saving.

[0051] The network device may include at least one of a core network device, a third-party application device, an operation administration and maintenance (OAM), and an access network device. For example, in FIG1 , the network device is an access network device 101.

[0055] A terminal device (e.g., terminal device 102 in FIG1 ) is a device with wireless transceiver capabilities that can send signals to an access network device and / or receive signals from an access network device. A terminal device may also be referred to as a terminal, mobile station, mobile terminal, etc. A terminal device may be a mobile phone, tablet, or other device with wireless intelligent transceiver capabilities. Terminal devices can be widely used in various scenarios, such as device-to-device (D2D), vehicle-to-everything (V2X) communication, machine-type communication (MTC), Internet of Things (IoT), virtual reality, augmented reality, industrial control, autonomous driving, telemedicine, or various smart scenarios.

[0056] Access network devices and terminal devices, and terminal devices and terminal devices can communicate via licensed spectrum, unlicensed spectrum, or both. The present application embodiment does not limit the spectrum resources used for wireless communications.

[0057] For ease of description, the following description uses a base station as an example of an access network device.

[0058] In each embodiment of the present application, cell discontinuous transmission / reception (DTX / DRX) may also be referred to as cell discontinuous transmission or reception, which have the same meaning and can be used interchangeably.

[0059] Embodiments of the first aspect

[0060] Time-domain energy saving of the network can be divided into two modes. Mode 1 is cell discontinuous transmission / reception (DTX / DRX), that is, by configuring the cell active period (active period) and inactive period (non-active period or inactive period) in the network equipment, the network equipment only sends and receives signals during the active period, and limits the sending and receiving of signals during the inactive period. Mode 2 is cell sleep or shutdown. Once the cell enters sleep or shutdown, the network equipment will stop sending and receiving all signals in this cell. The UE served by this cell needs to handover to other cells before the cell enters sleep or shutdown.

[0061] In the following description of this application, cell dormancy or shutdown is sometimes referred to as cell shutdown.

[0062] Figure 2 illustrates a cell DTX / DRX operation. As shown in Figure 2, the network uses terminal-specific Radio Resource Control (RRC) signaling to configure periodic cell DTX / DRX settings, including the cycle, start slot or start slot offset, and on duration. Time outside the on duration is considered inactive.

[0063] Cell DTX and cell DRX can be configured separately, or only one of them can be configured.

[0064] The cell DTX setting and the cell DRX setting can be the same or different. For example, the activity time and cycle settings are the same, but the starting time slot settings are different.

[0065] During the cell DTX active period, the terminal device receives normal signals. During the cell DTX inactive period, the terminal device receives restricted signals. For example, the terminal device does not monitor the physical downlink control channel (PDCCH) and the semi-persistent scheduling-physical downlink shared channel (SPS-PDSCH). The terminal device does not receive the channel state information reference signal (CSI-RS) for periodic or semi-persistent channel measurement reports. The channel measurement report here can be a report containing the rank indication (RI) report quantity.

[0066] During the cell DRX active period, the terminal device transmits normal signals. During the cell DRX inactive period, the terminal device transmits restricted signals, for example, the terminal device does not send a scheduling request (SR) or a configuration grant-physical uplink shared channel (CG-PUSCH). The terminal device does not send periodic or semi-continuous channel measurement reports. The channel measurement report here can be a report containing the RI report quantity.

[0067] For the cell dormancy mode, the network equipment uses terminal equipment-specific RRC signaling to configure the cell switching settings for specific conditions in the network energy-saving mode, including cell switching measurement conditions, target service cell information, cell switching execution conditions, etc.

[0068] During conditional handover, the device does not wait until the signal is completely lost or unavailable. Instead, it switches to the target serving cell when specific conditions are met. For example, if the device receives a signal that the current serving cell is about to go dormant or shut down, and if it finds a target serving cell that meets the conditions through measurement, the device can switch from the current serving cell to the target serving cell.

[0069] In order to flexibly and efficiently notify terminal devices of information related to network energy saving, an embodiment of the first aspect of the present application provides a method for receiving indication information, which is applied to a terminal device, such as the terminal device 102 shown in Figure 1.

[0070] FIG3 is a schematic diagram of a method for receiving indication information according to an embodiment of the first aspect of the present application. As shown in FIG3 , the method for receiving indication information includes:

[0071] Operation 301: Receive a first configuration from a network device, where the first configuration is used to configure conditional switching;

[0072] Operation 302: Receive first downlink control information (DCI) from the network device in a first serving cell, where the first DCI includes first information and / or second information, where the first information is used to indicate dormancy or shutdown information related to A serving cells of the terminal device, and the second information is used to activate or deactivate discontinuous transmission or reception (DTX / DRX) of B serving cells of the terminal device, where A and B are positive integers; and

[0073] Operation 303: The terminal device performs operations related to condition switching.

[0074] In the present application, the first DCI may be, for example, a group-common DCI.

[0075] In operation 301 of the present application, the conditional switching may be used, for example, to save energy on network devices.

[0076] The first configuration may be, for example, a cell handover configuration under specific conditions in an energy-saving mode of the network device. The first configuration includes at least one of the following: a measurement object; a reporting configuration; a measurement identity (measId); a conditional handover reconfiguration identifier (CondReconfigId); or a measurement event.

[0077] A measurement object refers to information related to the target cell measured by the terminal device, and multiple items can be set in a list. For example, intra-frequency measurements, inter-frequency measurements, and inter-RAT (Radio Access Technology) E-UTRA measurements can all be configured as measurement objects. In the case of inter-RAT (Radio Access Technology) E-UTRA measurements, the EUTRA frequency is configured as the measurement object.

[0078] In addition, a measurement object may include a cell list with a cell-specific offset, a blocked cell list, and an allowed cell list. The cell-specific offset refers to the offset value added to the measurement result during measurement. The blocked cell list refers to a list of cells indicated as non-relevant (out of range) in an event assessment or measurement report. The allowed cell list refers to a list of cells indicated as relevant (in range) in an event assessment or measurement report. To manage measurement objects, the network device sets a measurement object identifier (measObjectId) for each measurement object.

[0079] The report configuration contains information related to the measurement report and can set one or more report configurations for each measurement object. To manage the report configurations, the network device sets a report configuration identifier (reportConfigId) for each report configuration.

[0080] The measurement identifier (measId) is used to associate a measurement object identifier (measObjectId) with a report configuration identifier (reportConfigId). Multiple measurement identifiers can be set in a list. Using measurement identifiers, you can associate multiple report configurations with a single measurement object, or you can associate multiple measurement objects with the same report configuration.

[0081] The conditional switch reconfiguration identifier (CondReconfigId) is used to identify and manage conditional switch settings. By associating the conditional switch reconfiguration identifier (CondReconfigId) with the measurement identifier (measId), the conditions of the measurement event can be specified.

[0082] The measurement event includes, for example, at least one of an A3 event, an A4 event, and an A5 event, etc. Wherein:

[0083] A3 event: When the signal quality of the neighboring cell is better than that of the special service cell by an offset, the A3 event is triggered.

[0084] A4 event: When the signal strength of the neighboring cell exceeds the preset threshold, the A4 event is triggered.

[0085] A5 event: When the signal strength of the special service cell is lower than the preset threshold 1 and the signal strength of the neighboring cell is lower than the preset threshold 2, the A5 event is triggered.

[0086] In addition, the first configuration may further include at least one of the following: target serving cell information, handover parameters, reselection parameters, and handover execution conditions.

[0087] The target serving cell information includes information such as the cell ID of the target serving cell;

[0088] The switching parameters include parameters that need to be considered when determining whether a measurement event is satisfied, such as threshold parameters;

[0089] Reselection parameters refer to information on how the terminal device reselects the serving cell after switching, such as reselection threshold, reselection timer and other parameters.

[0090] The handover execution condition includes, for example, receiving a DCI format notification indicating that the source serving cell is about to enter a dormant / off state, and the UE finds a target serving cell that meets the measurement event through measurement.

[0091] In at least one embodiment of operation 301 , the terminal device may further receive at least one of a second configuration, a third configuration, and a fourth configuration from the network device.

[0092] The second configuration is used to configure the A serving cells to be dormant or shut down.

[0093] The third configuration is used to configure cell discontinuous transmission and / or cell discontinuous reception of the B serving cells. For example, the third configuration is used to configure cell discontinuous transmission of the B serving cells, and the third configuration may include cellDTXConfig; for another example, the third configuration is used to configure cell discontinuous reception of the B serving cells, and the third configuration may include cellDRXConfig.

[0094] In at least one embodiment, when the third configuration is used to configure the discontinuous transmission of the B serving cells, the third configuration may include one or more of the following: cell DTX cycle, cell DTX start slot or start slot offset (start slot / offset), and cell DTX active time (on duration).

[0095] When the third configuration is used to configure cell discontinuous reception of the B serving cells, the third configuration may include at least one of the following content: cell DRX cycle, cell DRX start slot or start slot offset (start slot / offset), and cell DRX on duration.

[0096] If the third configuration is used to configure cell discontinuous reception and cell discontinuous transmission of the B serving cells, then the configuration of cell discontinuous reception and cell discontinuous transmission may be the same or different. For example, the active time and period settings may be the same, but the starting time slot settings may be different.

[0097] The third configurations of different serving cells may be the same or different.

[0098] The fourth configuration is used to configure information related to the reception of the first DCI. The fourth configuration includes at least one of the following: the size of the first DCI (e.g., sizeDCI-2-9); the radio network temporary identifier (RNTI) of the network energy saving mode used for cyclic redundancy check (CRC) scrambling of the first DCI, e.g., NESCHO-RNTI; the search space of the first DCI; the starting bit position that the terminal device needs to monitor, e.g., positionInDCI-cellDTRX; and the corresponding information of the starting bit position that the terminal device needs to monitor and the cell ID of the serving cell (or a combination of cell IDs of multiple serving cells).

[0099] The serving cell may be a primary serving cell (PCell), a secondary serving cell (SCell), or a special serving cell (SpCell). The one or more serving cells may be within a cell group or within different cell groups. A special serving cell refers to a primary serving cell in a master cell group or a secondary cell group.

[0100] In the present application, for A and B described in operation 302, A may be equal to B, or A and B may not be equal. The A serving cells and the B serving cells may be completely identical, partially overlap, or have no overlap.

[0101] In the present application, there may be multiple embodiments of the first DCI carrying the first information and / or the second information.

[0102] In at least some embodiments, the first information may be carried by A blocks in the first DCI, and / or the second information may be carried by B blocks in the first DCI. The A blocks correspond one-to-one to the A serving cells, and / or the B blocks correspond one-to-one to the B serving cells, and the one-to-one correspondence is configured by the network device. Furthermore, the starting bit position of each block is determined by a higher-layer parameter. Each block includes at least one bit, or each block includes a bitmap.

[0103] In at least some other embodiments, the first information is carried by A1 blocks in the first DCI, and the second information is carried by B1 blocks in the first DCI, where A1 and B1 are positive integers, A1 is less than or equal to A, and B1 is less than or equal to B. The A1 blocks correspond one-to-one with the A1 serving cell groups, and / or the B1 blocks correspond one-to-one with the B1 serving cell groups, and the one-to-one correspondence is configured by the network device. In addition, the starting bit position of each block is determined by a high-level parameter. Each block includes at least one bit, or each block includes a bitmap.

[0104] For example, the A serving cells are an A1 serving cell group, and / or the B serving cells are a B1 serving cell group.

[0105] In at least one embodiment of the present application, in the first DCI, a block may include at least one of a first bit, a second bit, and a third bit, wherein the first bit, the second bit, and the third bit each include at least one bit.

[0106] Among them, the first bit is used to indicate the activation or deactivation of non-continuous transmission of the service cell or service cell group corresponding to the block; the second bit is used to indicate the activation or deactivation of non-continuous reception of the service cell or service cell group corresponding to the block; the third bit is used to indicate the sleep or shutdown information of the service cell or service cell group corresponding to the block.

[0107] For example, the third bit position includes 1 bit position: the 1 bit position is the first value, used to indicate that the service cell or service cell group corresponding to the block is not shut down or is not in sleep mode or is about to be shut down or in sleep mode; the 1 bit position is the second value, used to indicate that the service cell or service cell group corresponding to the block is about to be shut down or in sleep mode.

[0108] In an embodiment in which a block may include at least one of a first bit, a second bit, and a third bit, in the block including the first bit, the second bit, and the third bit:

[0109] The first bit is the most significant bit of the block, the second bit is the second most significant bit, and the third bit is the least significant bit; or

[0110] The third bit is the most significant bit of the block, the second bit is the second most significant bit, and the first bit is the least significant bit.

[0111] In at least one embodiment, the terminal device receives the second configuration in operation 301, the second serving cell or the second serving cell group of the terminal device is included in the A serving cells, and the block corresponding to the second serving cell or the second serving cell group in the first DCI includes at least the third bit; and / or,

[0112] The terminal device receives the third configuration, the second serving cell or the second serving cell group of the terminal device is included in the B serving cells, the third configuration includes the cell discontinuous transmission configuration of the second serving cell or the second serving cell group, and the block corresponding to the second serving cell or the second serving cell group in the first DCI includes at least the first bit; and / or,

[0113] The terminal device receives the third configuration, the second service cell or second service cell group of the terminal device is included in the B service cells, the third configuration includes the cell discontinuous reception configuration of the second service cell or the second service cell group, and the block corresponding to the second service cell or the second service cell group in the first DCI includes at least the second bit.

[0114] In at least another embodiment, the terminal device receives the second configuration and the third configuration in operation 301. The third serving cell or the third serving cell group of the terminal device is included in both the A serving cells and the B serving cells, and the first information and the second information corresponding to the third serving cell or the third serving cell group are carried by one block.

[0115] For example, the block used to carry the first information corresponding to the third service cell or the third service cell group is the same as the block used to carry the second information corresponding to the third service cell, that is, the first information and the second information corresponding to the third service cell or the third service cell group are carried by the same block.

[0116] In addition, in other embodiments of the present application, the first information and the second information may also be carried by different blocks, or the scrambling method of the first DCI containing the first information may be different from the scrambling method of the first DCI containing the second information. The description of these other embodiments will be expanded in subsequent embodiments.

[0117] Through operation 302, the terminal device 302 receives the first DCI and is able to obtain the first information and / or the second information, thereby being instructed with information related to energy saving of the network device.

[0118] In operation 303 of the present application, the terminal device performs an operation related to conditional switching, wherein the operation related to conditional switching includes at least one of the following operations:

[0119] performing conditional switching based on at least the first configuration;

[0120] The terminal device cancels the conditional switching associated with the first configuration, wherein canceling the conditional switching associated with the first configuration may also be referred to as stopping, suspending, releasing, or terminating the conditional switching associated with the first configuration.

[0121] In operation 303, the terminal device performs an operation related to conditional switching, wherein the operation related to conditional switching may further include at least one of the following operations:

[0122] The terminal device receives the first information in the first time slot (m) of the first serving cell, where the first information indicates that the fourth serving cell of the terminal device is about to be shut down or dormant;

[0123] The terminal device uses the fourth serving cell as a source cell to perform the conditional switching.

[0124] In operation 303, the terminal device performs an operation related to conditional switching, wherein the operation related to conditional switching may further include at least one of the following operations:

[0125] The terminal device receives the first information in a first time slot (for example, time slot m) of the first serving cell, where the first information indicates that the fifth serving cell of the terminal device is not shut down or is not dormant, or that the shut down or dormancy of the fifth serving cell is about to end;

[0126] The terminal device cancels the ongoing conditional switching with the fifth serving cell as the source cell, wherein canceling the conditional switching can be referred to as stopping, suspending, releasing, or terminating the conditional switching.

[0127] In operation 303, the terminal device may perform the following operations related to conditional switching:

[0128] The terminal device determines, based at least on the first configuration, that the sixth cell is the target cell, and the terminal device performs conditional switching using the fourth serving cell as the source cell and the sixth cell as the target cell; and / or,

[0129] From the second time slot (for example, time slot m+d1, d1 is a natural number) to the third time slot (for example, m+d2, d2 is a positive integer), the terminal device does not monitor the first DCI; and / or,

[0130] Before the conditional switching operation is completed, the terminal device does not monitor the first DCI.

[0131] Wherein, d1 is the number of time slots of the subcarrier spacing (SCS) of the active downlink partial bandwidth (DL BWP) of the fourth serving cell. The value of d1 can be zero, or the value of d1 is the same as the value in Table 1.

[0132] Table 1

[0133] d2 corresponds to the number of timeslots of the SCS of the active DL BWP of the fourth serving cell. The value of d2 may be the same as or different from the value in Table 1. Alternatively, the difference between d1 and d2 may be the same as the value in Table 1.

[0134] In addition, in the present application, the first DCI is used to carry the block of the first information corresponding to the seventh serving cell or the seventh serving cell group and the block for carrying the second information corresponding to the seventh serving cell or the seventh serving cell group, and the block carrying the first information and the block carrying the second information (for example, the index of the block carrying the first information and the index of the block carrying the second information) are the same or different:

[0135] The terminal device does not expect the block carrying the first information and the block carrying the second information to be valid at the same time; and or,

[0136] The terminal device does not expect that the first information indicates that the seventh serving cell or the seventh serving cell group is turned off or dormant and the second information indicates a change in the activation or deactivation state of the seventh serving cell or the seventh serving cell group for discontinuous transmission or reception; and or,

[0137] The first information indicates that the seventh service cell or the seventh service cell group is closed or dormant, and the terminal device ignores or does not monitor or report to the upper layer or does not receive the second information.

[0138] The following describes the indication information receiving method of the present application shown in FIG3 in combination with different examples.

[0139] Example 1:

[0140] In Example 1, the indication information receiving method may include operations 301, 302, and 303 shown in FIG. 3 .

[0141] In Example 1, the description of operation 301 may refer to the above description.

[0142] In operation 302 of Example 1, the terminal device receives a first DCI (eg, group common DCI) sent by a network device. The first DCI is scrambled by a time domain network energy saving RNTI (eg, NESCHO-RNTI) using, for example, a CRC.

[0143] Figure 4 is a schematic diagram of the first DCI. As shown in Figure 4, the first DCI has at least one block, namely, block 1, block 2, ..., block N, where the starting bit position of the block is determined by a parameter (e.g., positionInDCI-cellDTRX) configured for the terminal device by a higher layer (e.g., the RRC layer). One block corresponds to one serving cell or one serving cell group. The starting bit position of the block and the corresponding serving cell or serving cell group are determined by parameters configured by the higher layer.

[0144] In Example 1, the terminal device is configured with cell handover configuration information for specific conditions in cell DTX and / or cell DRX and / or network energy-saving mode. The upper layer configures one or more blocks for the terminal device and defines the following fields for each block:

[0145] Cell DTX (i.e., the first bit) / Cell DRX (i.e., the second bit) / Cell shutdown (i.e., the third bit)

[0146] If the terminal device receives the second configuration and the third configuration, and the third configuration is used to configure cell DTX and cell DRX, the first bit, the second bit, and the third bit may each have 1 bit.

[0147] For example, the most significant bit (MSB) corresponds to the first bit, the second most significant bit (SMB) corresponds to the second bit, and the least significant bit (LSB) corresponds to the third bit.

[0148] For example, the most significant bit (MSB) corresponds to the third bit, the second most significant bit (SMB) corresponds to the second bit, and the least significant bit (LSB) corresponds to the first bit.

[0149] In addition, the first bit, the second bit, and the third bit may also have other setting forms.

[0150] If the terminal device receives two of the second configuration, the third configuration for configuring cell DTX, and the third configuration for configuring cell DTX, each block of the first DCI may include 2 bits, corresponding to two of the first bit, the second bit, and the third bit respectively.

[0151] For example, if the terminal device receives the third configuration, which is used to configure cell DTX and cell DRX, the MSB of the block corresponds to the first bit and the LSB corresponds to the second bit. In addition, the first bit, the second bit and the third bit may also have other setting forms.

[0152] If the terminal device receives both the second configuration, the third configuration for configuring cell DTX, and the third configuration for configuring cell DTX, each block of the first DCI may include 1 bit corresponding to one of the first bit, the second bit, and the third bit.

[0153] If the terminal device receives the third configuration for configuring cell DTX, the bit corresponds to the first bit position; if the terminal device receives the third configuration for configuring cell DRX, the bit corresponds to the second bit position.

[0154] Corresponding to the first bit and / or the second bit, a bit of 0 may indicate that the cell DTX and / or the cell DRX is deactivated, and a bit of 1 may indicate that the cell DTX and / or the cell DRX is activated.

[0155] Corresponding to the third bit, for example, the bit is 0 indicating that the service cell or service cell group is not shut down, 1 indicating that the service cell or service cell group is about to be shut down, or 0 indicating that the service cell or service cell group is about to be shut down, 1 indicating that the service cell or service cell group is not shut down.

[0156] In the present application, the size of the first DCI may be aligned with the sizes of other DCIs, for example, and may be indicated by a higher layer parameter (eg, sizeDCI).

[0157] If the terminal device has established connections with multiple service cells, the terminal device does not expect to monitor the physical downlink control channels (PDCCHs) of multiple service cells to detect the first DCI; or, the terminal device does not expect to monitor the PDCCHs of multiple service cells within a cell group to detect the first DCI.

[0158] In operation 303 of Example 1, the terminal device performs the following operations:

[0159] If the first DCI indicates activation or deactivation of cell DTX or cell DRX, then:

[0160] When the terminal device receives the PDCCH providing the first DCI on the time slot m of the active DL BWP of the serving cell 1, and the first DCI indicates the change in the activation or deactivation status of the current cell DTX or cell DRX of the serving cell 2, the terminal device will perform the corresponding switching signal sending and receiving behavior mode (UE behavior) on the serving cell 2 according to the indicated cell DTX or cell DRX, starting from the time slot on the active DL BWP or active UL BWP of the serving cell 2, which time slot is not earlier than the start of the time slot m+d0 on the active DL BWP of the serving cell 1. For the description of d0, refer to Table 1.

[0161] Among them, serving cell 1 and serving cell 2 may be the same or different.

[0162] If the first DCI indicates cell deactivation, then:

[0163] When the terminal device receives a PDCCH providing the DCI format in time slot m of the active DL BWP of serving cell 1, and the DCI format indicates a cell shutdown indication of the current cell of serving cell 2, the terminal device performs a cell handover operation under specific conditions (i.e., conditional handover) in the network energy saving mode, wherein:

[0164] If the terminal device finds a target serving cell that meets the specific conditions in the network energy-saving mode, the terminal device immediately performs a cell switching operation;

[0165] The terminal device does not need to monitor the PDCCH to detect the DCI format during time slot m+d1 to time slot m+d2, where d1 and d2 correspond to the time slot numbers of the SCS of the active DL BWP of serving cell 1, and the difference between d1 and d2 may be the same as or different from the value in Table 1; alternatively, the terminal device does not need to monitor the PDCCH to detect the DCI format before completing the cell switching operation.

[0166] For the first information and the second information contained in the block corresponding to the same serving cell or serving cell group, the terminal device does not expect the following two indications at the same time:

[0167] Changes in the activation or inactivation status of cell DTX or cell DRX; and

[0168] The community is closed.

[0169] Alternatively, for a block corresponding to a service cell or a service cell group, if the cell is indicated to be closed, the terminal device ignores the second information contained in the block corresponding to the same service cell or service cell group (i.e., the indication of activation or deactivation of cell DTX or cell DRX), for example, ignores or does not monitor or report to the upper layer or does not receive the second information.

[0170] Specifically, in the case where a block includes the first information and the second information, the terminal device does not expect the following two indications at the same time:

[0171] Changes in the activation or inactivation status of cell DTX or cell DRX; and

[0172] The community is closed.

[0173] Alternatively, if a block indicates that a cell is shut down, the terminal device ignores the second information contained in the same block (i.e., an indication of activation or deactivation of cell DTX or cell DRX), for example, ignores or does not monitor or report to the upper layer or does not receive the second information.

[0174] Example 2

[0175] In Example 2, the indication information receiving method may include operations 301, 302, and 303 shown in FIG. 3 .

[0176] In Example 2, the description of operation 301 can refer to operation 301 of Example 1. In addition, in Example 2, the starting bit position that the terminal device needs to monitor included in the fourth configuration information received by operation 301 can be one or more, that is, the starting bit position can be the starting bit position corresponding to the block of the first information, and / or the starting bit position corresponding to the block of the second information, for example, positionInDCI-cellDTRX and / or positionInDCI-NESCHO. In addition, in Example 2, the fourth configuration information received by operation 301 can also include corresponding information of the starting bit position that the terminal device needs to monitor and the cell ID of the serving cell (or a combination of cell IDs of multiple serving cells).

[0177] In operation 302 of Example 2, the terminal device receives a first DCI (eg, group common DCI) sent by a network device. The first DCI is scrambled by a time domain network energy saving RNTI (eg, NESCHO-RNTI) using, for example, a CRC.

[0178] In an example of Example 2:

[0179] The terminal device receives the third configuration, the ninth service cell or the ninth service cell group of the terminal device is included in at least the B service cells, the third configuration includes the cell discontinuous transmission configuration and the discontinuous reception configuration of the ninth service cell or the ninth service cell group, and the second block for carrying the second information corresponding to the ninth service cell or the ninth service cell group in the first DCI includes a first bit and a second bit; or,

[0180] The terminal device receives the third configuration, where a ninth serving cell or a ninth serving cell group of the terminal device is included in at least the B serving cells, the third configuration includes a cell discontinuous transmission configuration or a discontinuous reception configuration of the ninth serving cell or the ninth serving cell group, and the second block in the first DCI for carrying the second information corresponding to the ninth serving cell or the ninth serving cell group includes the first bit or the second bit;

[0181] The first bit and the second bit each include at least one bit.

[0182] In another example from Example 2:

[0183] The terminal device receives the second configuration, the ninth service cell or the ninth service cell group is also included in the A service cells, and the first information corresponding to the ninth service cell or the ninth service cell group is carried by the first block of the first DCI.

[0184] The starting bit position of the first block is determined by a first higher-level parameter, and the starting bit position of the second block is determined by a second higher-level parameter; the first higher-level parameter and the second higher-level parameter are carried by the fourth configuration. The second block includes a third bit position, wherein the third bit position includes at least one bit position, or the third bit position includes a bitmap.

[0185] Figure 5 is a schematic diagram of the first DCI. As shown in Figure 5, the first DCI has at least one block, namely, block 1, block 2, ..., block N, wherein the starting bit position that the terminal device needs to monitor is determined by parameters (e.g., positionInDCI-cellDTRX and / or positionInDCI-NESCHO) configured for the terminal device by a higher layer (e.g., the RRC layer). A block corresponds to a serving cell or a serving cell group, and the starting bit position of the block and the corresponding serving cell or serving cell group are determined by parameters configured by the higher layer.

[0186] If the terminal device receives a third configuration that configures cell DTX and / or cell DRX, the higher layer configures one or more blocks corresponding to the starting bit position indicated by the first higher layer parameter (e.g., positionInDCI-cellDTRX) for the terminal device, defining a first bit position and / or a second bit position for each block.

[0187] If the third configuration received by the terminal device configures cell DTX and cell DRX, the first bit and the second bit each include 1 bit, that is, the block corresponding to the second information has 2 bits. The MSB of the block corresponds to the first bit, and the LSB corresponds to the second bit; or the MSB of the block corresponds to the second bit, and the LSB corresponds to the first bit.

[0188] If the third configuration received by the terminal device is configured with cell DTX or cell DRX, the block corresponding to the second information has 1 bit. For example, if the third configuration is configured with cell DTX, the bit corresponds to the first bit; if the third configuration is configured with cell DRX, the bit corresponds to the second bit.

[0189] Corresponding to the first bit or the second bit, the value of the bit is 0 for deactivation and 1 for activation, or 1 for deactivation and 0 for activation.

[0190] If the terminal device receives the second configuration, the higher layer configures one or more blocks corresponding to the starting bit position indicated by the second higher layer parameter (eg, positionInDCI-NESCHO) for the terminal device and defines a third bit for each block.

[0191] The third bit can indicate whether a serving cell or a combination of serving cells is shut down by one bit. The one bit can be 0 for not shutting down and 1 for about to shut down; or 0 for about to shut down and 1 for not shutting down.

[0192] The third bit may also be a bitmap. In this bitmap, each bit corresponds to a serving cell or a combination of serving cells. The size of the bitmap is determined by a higher-layer configuration parameter. For example, the bitmap size is consistent with the number or number of serving cells configured by the higher-layer.

[0193] In the bitmap, for the value of each bit, for example, 0 represents a non-closing indication, and 1 represents an indication that is about to be closed, or 0 represents an indication that is about to be closed, and 1 represents a non-closing indication.

[0194] In Example 2, in the present application, the size of the first DCI may be aligned with the sizes of other DCIs, for example, and may be indicated by a higher layer parameter (eg, sizeDCI).

[0195] If the terminal device has established connections with multiple service cells, the terminal device does not expect to monitor the physical downlink control channels (PDCCHs) of multiple service cells to detect the first DCI; or, the terminal device does not expect to monitor the PDCCHs of multiple service cells within a cell group to detect the first DCI.

[0196] Operation 303 of Example 2 is the same as operation 303 of Example 1.

[0197] Example 3

[0198] In Example 3, the indication information receiving method may include operations 301, 302, and 303 shown in FIG. 3 .

[0199] In Example 3, the description of operation 301 may refer to operation 301 in Example 1. In addition, in Example 3, the fourth configuration information received in operation 301 may further include: the first RNTI and / or the second RNTI.

[0200] The first RNTI is an RNTI (e.g., NESCHO-RNTI) related to conditional switching (e.g., cell switching under specific conditions in network energy saving mode). The second RNTI is an RNTI used to scramble the second DCI. The second RNTI may be an RNTI for non-connected transmission or reception of a cell, e.g., cellDTRX-RNTI.

[0201] The second DCI includes second information, and the second information is used to activate or deactivate cell discontinuous transmission or reception (Cell DTX / DRX) of B service cells or B1 service cell groups of the terminal device, where B and B1 are positive integers.

[0202] In Example 3, the fourth configuration information received by operation 301 may include: the search space of the first DCI and / or the second DCI, the starting bit position that one or more terminal devices need to monitor (for example, positionInDCI-cellDTRX and / or positionInDCI-NESCHO), the starting bit position that the terminal device needs to monitor and the cell ID of the service cell (or a combination of cell IDs of multiple service cells) corresponding information.

[0203] In operation 302 of Example 3, the terminal device receives a first DCI (eg, group-common DCI) sent by a network device. The first DCI is scrambled by a first RNTI (eg, NESCHO-RNTI) using, for example, a CRC.

[0204] The first DCI may have block 1, block 2, ..., block N, where the starting bit position of the block is determined by a parameter (eg, positionInDCI-NESCHO) configured by a higher layer (RRC layer) for the terminal device.

[0205] The block corresponds to a serving cell or a serving cell group. The starting bit position of the block and the corresponding serving cell or the corresponding serving cell group are determined by parameters configured by a higher layer.

[0206] The upper layer configures one or more blocks for the terminal device and defines a third bit for each block. The third bit is used to indicate that the serving cell or serving cell group is closed.

[0207] The third bit may be 1 bit, corresponding to a serving cell or a serving cell group. For example, if the bit is 0, it indicates that the service is not shut down, and if it is 1, it indicates that the service is about to be shut down. Alternatively, if the bit is 0, it indicates that the service is about to be shut down, and if it is 1, it indicates that the service is not shut down.

[0208] The third bit may also be a bitmap. One bit in the bitmap corresponds to one serving cell or one serving cell group. The size of the bitmap is determined by a higher-layer configuration parameter. For example, the bitmap size is consistent with the number of serving cells or groups configured by the higher-layer.

[0209] For the value of each bit in the bitmap, for example, 0 indicates not closing, and 1 indicates an indication of about to close; or, 0 indicates about to close, and 1 indicates not closing.

[0210] In operation 302 of Example 3, the terminal device receives a second DCI (eg, group-common DCI) sent by the network device. The second DCI is scrambled by a second RNTI (eg, cellDTRX-RNTI) using, for example, a CRC.

[0211] The second DCI may have block 1, block 2, ..., block N, where the starting bit position of the block is determined by a parameter (eg, positionInDCI-cellDTRX) configured by a higher layer (RRC layer) for the terminal device.

[0212] The block corresponds to a serving cell or a serving cell group. The starting bit position of the block and the corresponding serving cell or the corresponding serving cell group are determined by parameters configured by a higher layer.

[0213] Each block of the second DCI may carry the second information.

[0214] The upper layer configures one or more blocks for the terminal device and defines a first bit and / or a second bit for each block. The first bit indicates cell DTX, and the second bit indicates cell DRX.

[0215] If the third configuration received by the terminal device configures cell DTX and cell DRX, the second information of the block is 2 bits, for example, the MSB of the block corresponds to the first bit, and the LSB corresponds to the second bit.

[0216] If the third configuration received by the terminal device configures one of cell DTX and cell DRX, the second information of the block is 1 bit. For example, if the third configuration received by the terminal device configures cell DTX, the 1 bit corresponds to the first bit; if the third configuration received by the terminal device configures cell DRX, the 1 bit corresponds to the second bit.

[0217] Corresponding to 1 bit in the first bit and / or the second bit, if the 1 bit is 0, it indicates deactivation, and if 1 is, it indicates activation; or, if the 1 bit is 1, it indicates deactivation, and if 0 is, it indicates activation.

[0218] In Example 3, in the present application, the size of the first DCI and / or the second DCI may be aligned with the size of other DCIs, for example, and may be indicated by a higher layer parameter (eg, sizeDCI).

[0219] If the terminal device has established connections with multiple service cells, the terminal device does not expect to monitor the physical downlink control channels (PDCCHs) of multiple service cells to detect the first DCI; or, the terminal device does not expect to monitor the PDCCHs of multiple service cells within a cell group to detect the first DCI.

[0220] If the terminal device has established connections with multiple service cells, the terminal device does not expect to monitor the physical downlink control channels (PDCCHs) of multiple service cells to detect the second DCI; or, the terminal device does not expect to monitor the PDCCHs of multiple service cells within a cell group to detect the second DCI.

[0221] Operation 303 of Example 3 is the same as operation 303 of Example 1.

[0222] In the present application, the above operations 403, 405 and 406 can be used as a separate embodiment to implement: the terminal device side monitors the resource information on the terminal device side based on the monitoring configuration information of the network device and reports it to the network device.

[0223] According to an embodiment of the first aspect of the present application, a terminal device receives downlink control information (DCI) related to network energy saving from a network device, thereby being able to flexibly and efficiently notify the terminal device of information related to network energy saving, thereby being able to improve network efficiency and network energy saving gains.

[0224] Embodiments of the second aspect

[0225] The embodiment of the second aspect provides a method for sending indication information, which is used to solve the same or similar technical problems as those described in the embodiment of the first aspect. The method is applied to a network device, such as the network device 101 shown in FIG1 .

[0226] FIG6 is a schematic diagram of a method for sending indication information according to an embodiment of the second aspect of the present application. As shown in FIG6 , the method for sending indication information includes:

[0227] Operation 601: Send a first configuration to a terminal device, where the first configuration is used to configure conditional switching;

[0229] In this application, the terminal device can perform operations related to conditional switching, including at least one of the following operations:

[0231] The terminal device cancels the conditional switching related to the first configuration.

[0232] In at least one embodiment, conditional switching is used to save energy in network devices.

[0233] In at least one embodiment, the first configuration includes:

[0239] In at least one embodiment, the first DCI is a group-common DCI.
