Description

[Technical Field]

[0001] The present invention relates to the field of communications. [Background technology]

[0002] Because NR (New Radio) base stations must operate over a large bandwidth (e.g., 100 MHz), they require a large number of ports (64T / 64R) and shorter TTIs (transmission time intervals) (e.g., 1 ms). NR base stations consume much more energy than LTE base stations for functions such as baseband processing and digital front-ends. Additionally, the operating frequency (>6 GHz) of NR's Frequency Range 2 (FR2) is relatively high. The higher the frequency point, the greater the signal path loss. Therefore, NR designs generally use relatively narrow beams to transmit signals farther. As a result, the number of antenna units for analog beamforming in NR base stations increases significantly, and the number of RF units and RF channels for transmit and receive signals also increases accordingly. Each RF channel is equipped with one power amplifier (PA), and the power consumption of PAs accounts for approximately 80% of the base station's total power consumption. As the number of PAs increases, the base station's power consumption also increases. Currently, AAUs (active antenna units) in the FR1 (frequency range 1) band generally employ 192 antenna units (elements) and support 64 channels, far more than the maximum 8 channels of LTE.

[0003] According to carrier data, the average power consumption of a single NR base station is more than three times that of an LTE base station, and electricity accounts for approximately 50% of carriers' costs for deploying 5G (fifth-generation) networks. More importantly, even during non-traffic hours, NR base stations still consume significant energy. This is because base stations still need to transmit common signals, such as SSB (synchronization signal block), SIB1 (system information block type 1), and SI (system information), even when there is no traffic. This significantly reduces the energy efficiency of NR base stations. Therefore, NR network energy conservation (also known as energy conservation) remains a problem waiting to be solved.

[0004] It should be noted that the introduction of the above background art is intended to clearly and completely explain the technical solutions of the present invention and to facilitate understanding by those skilled in the art, and these technical solutions described in the background art of the present invention should not be construed as being known to those skilled in the art. Summary of the Invention [Problem to be solved by the invention]

[0005] In 3GPP Rel-15 / Rel-16, in an intra-band carrier aggregation (CA) scenario, a secondary cell (SCell) of a terminal device does not need to transmit synchronization signal blocks (SSBs), and the terminal device supports downlink synchronization of the SCell by SSBs transmitted from a special cell (SpCell). For the same station address, at least one cell transmits SSBs, and only the cell transmitting the SSBs can be the SpCell of the terminal device.

[0006] To save energy in the network, the network can dynamically activate and deactivate the UE's SpCell based on information such as traffic of the NR cell and its neighboring cells, UE measurement reports, etc. When a cell is deactivated, the network stops transmitting the SSB, SIB1, and SI of the cell and stops receiving uplink signals transmitted by the UE. In this way, the energy consumption of the SpCell can be reduced when traffic is relatively low.

[0007] Figure 1 shows a network energy saving scheme. As shown in Figure 1, when an NR cell enters an energy saving state, a base station switches UEs to a neighboring cell and notifies a neighboring NR base station or LTE base station that the NR cell is entering an energy saving state, and the neighboring NR base station or LTE base station is responsible for the coverage and traffic of the NR cell. The neighboring NR base station or LTE base station can then determine whether to request the NR cell that entered the energy saving state to resume normal operation based on information such as its own traffic and UE measurement reports. For example, when its own traffic reaches a predetermined threshold, it triggers the NR cell that entered the energy saving state to request that it resume normal operation. When the NR cell resumes normal operation, some UEs that were previously handed over to a neighboring NR base station or LTE base station may be switched to the NR cell.

[0008] The inventors discovered the following: In the above scheme, when an NR cell is in an energy saving state, the cell cannot transmit or receive any signals. Therefore, a UE originally connected to the cell must be handed over to a neighboring cell, and a UE originally staying in the cell must perform cell reselection to stay in the neighboring cell. When an NR cell dynamically enters an energy saving state multiple times, UEs must be frequently handed over from the NR cell or frequently perform cell reselection, which may affect the user experience. In addition, when a UE in a cell in an energy saving state moves to a neighboring cell, it may increase the load level of the neighboring cell, affecting the service quality of the UEs in the neighboring cell.

[0009] In view of at least one of the above problems, embodiments of the present invention provide an information processing method and apparatus. [Means for solving the problem]

[0010] According to one aspect of an embodiment of the present invention, there is provided an information processing device that is applied to a terminal device, the device comprising: a receiving unit for receiving indication information for indicating a first state and a second state of the cell with respect to downlink transmission; and a processing unit for receiving information from the cell based on the indication information; The cell is the cell in which the terminal device is located or the cell to which the terminal device is connected.

[0011] According to another aspect of the present invention, there is provided an information processing method, which is applied to a terminal device, the method comprising: receiving indication information for indicating a first state and a second state of the cell with respect to downlink transmission; and receiving information from the cell based on the indication information; The cell is the cell in which the terminal device is located or the cell to which the terminal device is connected.

[0012] According to another aspect of the embodiment of the present invention, there is provided an information processing device, which is applied to a network device, and the device includes: a transmitting unit that transmits, to a terminal device, indication information for indicating a first state and a second state of a cell regarding downlink transmission, and causes the terminal device to receive information from the cell based on the indication information; The cell is the cell in which the terminal device is located or the cell to which the terminal device is connected. [Effects of the Invention]

[0013] The advantageous effects of the embodiments of the present invention are at least as follows: A terminal device can receive indication information for indicating a first state and a second state regarding downlink transmission of a cell to which the terminal device is connected or located, and can receive information from the cell based on the indication information. Since a cell can switch between different states regarding downlink transmission, energy overhead of a network device can be saved. Furthermore, since a terminal device connected to or visiting the cell can receive information from the cell based on the indication information for indicating the first state and the second state of the cell, when a cell switches between the first state and the second state, the terminal device does not need to be handed over to another cell, and the terminal device originally visiting the cell does not need to perform cell reselection. This avoids traffic interruption and an increase in the load level of the neighboring cell caused by transferring a terminal device of the cell to a neighboring cell under an energy saving state, and prevents a degradation of user experience when a cell enters an energy saving state.

[0035] Hereinafter, the embodiments of the present invention will be described in conjunction with the drawings and specific implementation modes.

[0036] <Example of the first aspect> In the embodiments of the present invention, an information processing method is provided, which will be explained from the terminal equipment (UE) side.

[0037] FIG. 3 is a diagram illustrating an information processing method according to an embodiment of the present invention, which is applied to a terminal device. As shown in FIG. 3, the method includes the following steps:

[0038] 301: Receive indication information for indicating a first state and a second state of a cell regarding downlink transmission; and 302: Receive information from the cell based on the instruction information; Wherein, the cell is the cell where the terminal device is located or the cell to which the terminal device is connected.

[0039] Although the above-mentioned FIG. 3 exemplifies an embodiment of the present invention, the present invention is not limited thereto. For example, some other operations may be added or removed. Furthermore, those skilled in the art may make appropriate modifications based on the above-mentioned content without being limited to the above-mentioned FIG. 3.

[0040] In some embodiments, the cell may transmit fewer downlink signals when in the first state than when in the second state, allowing the cell to be switched between the first and second states to conserve network equipment overhead.

[0041] In some embodiments, the first state of a cell of a network device may be referred to as a transmission state (TX active) and the second state may be referred to as a non-transmission state (TX inactive). Switching of a cell between the first and second states may be referred to as discontinuous transmission (DTX) of the cell.

[0042] In some embodiments, the first state of the cell may include a first energy saving state, and the second state may include a non-energy saving state and / or a second energy saving state. Alternatively, the first state of the cell may include a first energy saving state and / or a second energy saving state, and the second state may include a non-energy saving state. Wherein, the downlink signal transmitted by the cell in the first energy saving state may be less than the downlink signal transmitted by the cell in the second energy saving state.

[0043] In some embodiments, a cell may have multiple energy saving modes, and the network device may allow the cell to enter different energy saving (ES) states. The energy saving states of the cell may include at least one of the following: a time domain energy saving state, a frequency domain energy saving state, a spatial domain energy saving state, and a power domain energy saving state. The cell may be in one of the above energy saving states, or may be in multiple of the above energy saving states simultaneously, for example, in a time domain energy saving state and a spatial domain energy saving state simultaneously.

[0044] In some embodiments, during the working period of a cell, the cell can switch between different energy saving states. The switching between different energy saving states may be realized by switching the configuration parameters of the cell or BWP (BandWidth Part), that is, when the configuration parameters of the cell or BWP are switched to the configuration parameters that support the corresponding energy saving state, the cell or BWP is switched to the energy saving state.

[0045] In some embodiments, the time domain energy saving state may include at least one of the following: -- stopping the transmission of common signals, e.g., stopping the transmission of SSBs (Synchronization Signal Blocks), SIBs (System Information Blocks) and / or paging; -- Stop transmitting common signals and UE-specific signals; -- Transmitting common signals with an extended transmission period, for example, extending the transmission period of SSBs (synchronization signal blocks), SIBs (system information blocks), and / or paging. For example, the transmission period of SSBs / SIBs is made longer than the transmission period of SSBs / SIBs in a normal service state (non-energy saving state). In a normal service state, the transmission period of SSBs is at most 160 ms, and in a time domain energy saving state, the transmission period of SSBs may be longer than 160 ms; -- transmitting a simplified common signal, where the simplified common signal may include a synchronization signal block (SSB) that does not include a main information block (MIB) or a physical broadcast channel (PBCH), for example, the transmitted SSB includes only a synchronization reference signal (SS) or includes a discovery reference signal (DRS) that includes a synchronization reference signal (SS); and -- Stop or reduce reception of signals, for example, stopping reception of semi-statically configured uplink signals, including the Physical Random Access Channel (PRACH), the Physical Uplink Shared Channel (PUSCH) of the Configuration Grant (CG), SRS, Scheduling Request (SR), periodic Channel State Information (CSI) reporting, and the Physical Uplink Control Channel (PUCCH), or stopping reception of dynamically scheduled uplink signals, including the PUSCH scheduled by Downlink Control Information (DCI), Hybrid Automatic Repeat Request (HARQ) feedback on the Physical Downlink Shared Channel (PDSCH), and aperiodic CSI reporting.

[0046] In the above-mentioned time domain energy saving state, the transmission or reception of a cell may be in the energy saving state respectively, or the transmission and reception of a cell may be in the energy saving state simultaneously. For example, a cell can transmit a downlink signal normally under the state of stopping or reducing the reception of a signal, or a cell can stop or reduce the transmission of a downlink signal under the state of stopping or reducing the reception of a signal, or a cell can receive a signal normally under the state of stopping or reducing the transmission of a downlink signal.

[0047] In some embodiments, from the perspective of downlink transmission, the time domain energy saving state can be further divided into a first time domain energy saving state and a second time domain energy saving state. For example, the first time domain energy saving state may include at least one of the following: stopping transmission of common signals and stopping transmission of common signals and UE dedicated signals. In the first time domain energy saving state, there is no restriction on received signals, that is, under the first time domain energy saving state, reception of uplink signals may be normal, stopped, or reduced.

[0048] The second time domain energy saving state may include at least one of the following: transmitting a common signal with an extended transmission period, transmitting a simplified common signal, and performing normal, stopping, or reducing uplink signal reception. Wherein, when transmitting a common signal with an extended transmission period or transmitting a simplified common signal under the second time domain energy saving state, there is no restriction on the received signal, that is, when transmitting a common signal with an extended transmission period or transmitting a simplified common signal, uplink signal reception may be performed normally, stopping, or reducing.

[0049] In some embodiments, the frequency domain energy saving state may include reducing the serving bandwidth, for example, reducing the uplink and downlink bandwidth of the initial BWP and the dedicated BWP.

[0050] In some embodiments, the spatial domain energy saving state may include at least one of the following: -- Reducing the number of antenna units or RF transmit / receive units (TxRUs); -- reducing the number of analog beams of transmission, e.g., reducing the number of SSB beams (indicated by ssb-PositionsInBurst); -- Reducing the number of transmit antenna ports (number of digital beamforming ports) for channel state information reference signals (CSI-RS); and -- Reducing the number of transmit / receive points (TRPs).

[0051] In some embodiments, the power domain energy saving states may include at least one of the following: -- reducing the transmission power of downlink reference signals or common signals, such as reducing the transmission power of SSBs, or reducing the transmission power of CSI-RSs, or reducing the transmission power of broadcast channels and paging; and -- Reducing the transmit power of the data channel.

[0052] In some embodiments, the above-mentioned first energy saving state may include the following: a first time domain energy saving state, or a combination of at least one of a first time domain energy saving state, a frequency domain energy saving state, a spatial domain energy saving state, and a power domain energy saving state.

[0053] In some embodiments, the above-mentioned second energy saving state may include at least one or a combination of a second time domain energy saving state, a frequency domain energy saving state, a spatial domain energy saving state, and a power domain energy saving state.

[0054] When the first state of a cell includes a first energy saving state and the second state includes a non-energy saving state and / or a second energy saving state, the cell stops transmitting common signals or stops transmitting common signals and dedicated signals under the first state, and the cell transmits signals normally under the second state or reduces the transmission of common signals at least in the time domain.

[0055] In other words, when a cell performs discontinuous transmission (DTX), the cell stops transmitting common signals or stops transmitting common signals and dedicated signals under a non-transmitting state (first state), and the cell transmits signals normally under a transmitting state (second state), or at least reduces the transmission of common signals in the time domain.

[0056] When the first state of a cell includes a first energy saving state and / or a second state, and the second state includes a non-energy saving state, the cell stops transmitting common signals under the first state, or stops transmitting common signals and dedicated signals, or reduces the transmission of common signals at least in the time domain, and the cell transmits signals normally under the second state.

[0057] In other words, when a cell performs discontinuous transmission (DTX), the cell stops transmitting common signals under a non-transmitting state (first state), or stops transmitting common signals and dedicated signals, or at least reduces the transmission of common signals in the time domain, and the cell transmits signals normally under a transmitting state (second state).

[0058] In some embodiments, the indication information may include various information that can indicate the first and second states of the cell, and the indication information can be set or indicated in various ways. The following provides an exemplary description of the indication information.

[0059] In some embodiments, the discontinuous transmission (DTX) of the cell can be semi-statically configured. For example, the indication information may include configuration information for a first timer, in which the cell is in the second state during the running period of the first timer. However, the present invention is not limited thereto, and the cell may be in the first state during the running period of the first timer. The following description will be given taking the cell in the second state during the running period of the first timer as an example.

[0060] In some embodiments, the setting information of the first timer may include at least one of the following: a running time duration of the first timer, an offset of the start time of the first timer, and an start period of the first timer.

[0061] 4 is a diagram illustrating switching times between the first state and the second state according to an embodiment of the present invention. In some embodiments, as shown in FIG. 4, the instruction information may indicate the running time duration of the first timer and the activation period of the first timer. During the running time duration of the first timer, the cell is in the second state, and during the other times, the cell is in the first state. This allows the UE to determine the times when the cell is in the first state and the second state based on the instruction information. Furthermore, the instruction information may further include an offset for the activation time of the first timer, which greatly enhances the flexibility of the first timer configuration.

[0062] In some embodiments, the instruction information including the setting information of the first timer may be transmitted by adding an information unit regarding the setting of discontinuous transmission (DTX) to the system broadcast message, although the present invention is not limited thereto and the instruction information may be transmitted in other manners.

[0063] In some embodiments, the indication information may include at least one of the following, and the UE determines the configuration information of the first timer according to the indication information: -- the length of time, period, and offset in the period that the cell is in a non-energy saving state; -- the length of time, period, and offset in the period that the cell is in the first energy saving state; and --The length of time, period, and offset in the period that the cell is in the second energy saving state.

[0064] 5 is a diagram illustrating switching times among the non-energy saving state, the first energy saving state, and the second energy saving state according to an embodiment of the present invention. In some embodiments, as shown in FIG. 5, the instruction information may include the duration, period, and offset of the period of the second energy saving state and the non-energy saving state. When the period of the first energy saving state is the same as the period of the non-energy saving state and the period of the second energy saving state, the sum of the duration of the second energy saving state and the non-energy saving state may be the running time length of the first timer, the period of the second energy saving state may be the activation period of the first timer, and the offset of the period of the second energy saving state and / or the non-energy saving state may be the offset of the activation time of the first timer.

[0065] In some embodiments, discontinuous transmission (DTX) of a cell may be dynamically indicated, for example, the indication information may include at least one of the following: first information for indicating a switch between a first state and a second state of the cell, and second information for indicating a switch between a non-energy saving state and at least one energy saving state of the cell.

[0066] In some embodiments, when the indication information includes first information, the network device may dynamically instruct a UE connected to or staying in the cell by a common signal that the cell is switched to a first state (TX inactive) or a second state (TX active), thereby informing the UE of the time when the cell stops or reduces downlink transmission and the time when the cell performs downlink transmission normally.

[0067] In some embodiments, the first information may be transmitted by a layer 1 (L1) or layer 2 (L2) common signal, where the L1 or L2 common signal may be an L1 or L2 common signal dedicated to indicating switching of the cell between the first state and the second state. However, the present invention is not limited thereto, and the first information may be transmitted in other manners.

[0068] In some embodiments, the first information may include information directing the cell to enter a first state and information directing the cell to enter a second state, or information directing the cell to leave the first state and information directing the cell to leave the second state.

[0069] In some embodiments, the first information may include information that directly instructs switching between the first state and the second state of the cell. Alternatively, when the cell supports BWP, the first information may include information for instructing switching between the BWP that supports the first state of the cell and the BWP that supports the second state of the cell. For example, when the first information instructs the UE to switch to the BWP that supports the first state of the cell, the UE may consider the cell to be in the first state, and when the first information instructs the UE to switch to the BWP that supports the second state of the cell, the UE may consider the cell to be in the second state.

[0070] In some embodiments, when the instruction information includes second information, the network device may use a common signal to instruct a UE connected to or camped in the cell to switch between different energy saving states of the cell. That is, the energy saving state switching instruction (second information) of the cell may be information indicating the first state and the second state of the cell. This eliminates the need to add a dedicated information unit for instructing the switching between the first state and the second state.

[0071] In some embodiments, the energy saving state switching instruction (second information) may include information for instructing the cell to be in one or more combinations of a time domain energy saving state, a frequency domain energy saving state, a power domain energy saving state, and a spatial domain energy saving state, and the energy saving state switching instruction (second information) may be used to switch configuration parameters of the terminal device to configuration parameters supporting one or more combinations of the time domain energy saving state, the frequency domain energy saving state, the power domain energy saving state, and the spatial domain energy saving state.

[0072] For example, when an energy saving state switching instruction instructs the cell to switch to an energy saving state that includes at least stopping or reducing downlink transmission (e.g., an energy saving state of stopping transmission of common signals, stopping transmission of common signals and UE-dedicated signals, transmitting simplified common signals, and transmitting common signals at an extended transmission period), the cell is in the first state, and when an energy saving state switching instruction instructs the cell to switch to an energy saving state in which downlink transmission is performed normally or reduced, the cell is in the second state.

[0073] In some embodiments, the energy saving state switching indication may be a switching indication for a time domain energy saving state, a frequency domain energy saving state, a power domain energy saving state, or a spatial domain energy saving state, respectively, and may be used to switch the cell or BWP configuration to configuration parameters that support the time domain energy saving state, the frequency domain energy saving state, the power domain energy saving state, or the spatial domain energy saving state.

[0074] In some embodiments, the energy saving state switching instruction may be a switching instruction that simultaneously instructs a time domain energy saving state, a frequency domain energy saving state, a power domain energy saving state, or a spatial domain energy saving state, and may be used to switch the configuration of a cell or a BWP to configuration parameters that simultaneously support multiple of the time domain energy saving state, the frequency domain energy saving state, the power domain energy saving state, or the spatial domain energy saving state.

[0075] In some embodiments, the energy saving state switching instruction may include information directly instructing switching of the energy saving state of the cell, or when the cell supports BWP, the second information may include information instructing switching between a non-energy saving BWP of the cell and at least one BWP that supports the energy saving state.

[0076] In some embodiments, the second information may be transmitted by a common signal of L1 or L2, although the present invention is not limited thereto and the second information may be transmitted in other ways.

[0077] In some embodiments, the L1 common signal for transmitting the first information and / or the second information may include a physical downlink control channel (PDCCH) scrambled by a network energy saving indicator (NES-RNTI), and the L2 common signal for transmitting the first information and / or the second information may include a MAC control unit (CE) scheduled by the PDCCH scrambled by the NES-RNTI, where the NES-RNTI may be broadcast and transmitted to the terminal device by the system. However, the present invention is not limited thereto, and the L1 or L2 common signal may be a common signal of another type.

[0078] In some embodiments, discontinuous transmission (DTX) may be dynamically indicated in other ways. For example, the indication information may include configuration information of a second timer, which may include a running time of the second timer, during which the cell is in the second state. However, the present invention is not limited to this, and the cell may be in the first state during the running time of the second timer. The following description will be given taking the example of the cell being in the second state during the running time of the second timer.

[0079] In some embodiments, the terminal device and the network device can simultaneously maintain the second timer, start or restart the second timer when a first predetermined condition is met, and switch the cell to the second state during the running period of the second timer, and stop the second timer when a second predetermined condition is met, and hand over the cell to the first state when the second timer expires or is stopped.

[0080] In some embodiments, the first predetermined condition for starting or restarting the second timer may include at least one of the following: receiving a common signal from the cell; or receiving a terminal equipment dedicated signal from the cell.

[0081] When the instruction information includes setting information for the second timer and first information for instructing the cell to switch between a first state and a second state or second information for instructing the cell to switch between a non-energy saving state and at least one energy saving state, the first predetermined condition for starting or restarting the second timer may further include at least one of the following: receiving first information for instructing the cell to enter the second state, and receiving second information for instructing the cell to enter a non-energy saving state and / or a second energy saving state.

[0082] In some embodiments, when the instruction information includes setting information for the second timer and first information for instructing the cell to switch between a first state and a second state or second information for instructing the cell to switch between a non-energy saving state and at least one energy saving state, the second predetermined condition for stopping the second timer may include at least one of the following: the cell has received first information for instructing it to enter the first state, and the cell has received second information for instructing it to enter the first energy saving state.

[0083] In some embodiments, the indication information including the setting information of the second timer may be transmitted by a system broadcast message, although the present invention is not limited thereto and the indication information may be transmitted in other manners.

[0084] In some embodiments, the instruction information may include configuration information for the first timer, or may include the first information and / or the second information, or may include configuration information for the second timer. The instruction information may also include a combination of the above information, for example, the instruction information may include configuration information for the first timer and configuration information for the second timer; or configuration information for the first timer and the first information and / or the second information; or configuration information for the second timer and the first information and / or the second information; or configuration information for the first timer, the first information and / or the second information, and configuration information for the second timer.

[0085] For example, when the instruction information includes the setting information of the first timer and the first information and / or the second information, when the instruction information includes the setting information of the first timer and the first information and / or the second information, the first timer is stopped if a third predetermined condition is satisfied, which may include at least one of the following: the cell receives first information to instruct it to enter the first state, and the cell receives second information to instruct it to enter the first energy saving state.

[0086] For example, when the instruction information includes the configuration information of the first timer, the configuration information of the second timer, and the first information and / or the second information, the time when the cell is in the first state and the second state can be jointly determined based on the configuration information of the first timer, the configuration information of the second timer, and the first information and / or the second information. For example, the time when the cell is in the second state is the downlink transmission duration (DTX On duration) within a statically configured discontinuous transmission period, i.e., the running period of the first timer, and the time when the cell is triggered to be in the TX active state by dynamic signaling, i.e., the running period of the second timer.

[0087] 6 is a diagram illustrating the activation or deactivation of a first timer and a second timer according to an embodiment of the present invention. As shown in FIG. 6, the first timer is activated at time A. At time B, the UE receives first information for instructing the cell to enter the second state or second information for instructing the cell to enter the non-energy saving state and / or the second energy saving state, and the second timer is activated. At time C, the first timer expires. At time D, the second timer expires. At time E, the first timer enters its next activation cycle. At time F, the UE receives first information for instructing the cell to enter the first state or second information for instructing the cell to enter the first energy saving state, and the first timer is stopped. In this process, the cell can transmit downlink signals to the UE from time A to time D and from time E to time F, and the cell stops or reduces the transmission of downlink signals at other times.

[0088] In some embodiments, the indication information may be transmitted in the cell indicated by the indication information, or the indication information may be transmitted in another cell of the network equipment to which the cell belongs, or the indication information may be transmitted in another network equipment adjacent to the network equipment to which the cell belongs.

[0089] For example, when the indication information is transmitted in a cell indicated by the indication information, the cell may transmit the indication information to a UE connected to or located in the cell when in the second state, and the network equipment may transmit the indication information at various times when the indication information is transmitted in another cell of the network equipment to which the cell belongs, or in another network equipment adjacent to the network equipment to which the cell belongs.

[0090] In some embodiments, for some downlink signals, the terminal device can receive these downlink signals only during the second period when the cell is in the second state. In this way, not only can the energy consumption of the network device be reduced during the discontinuous transmission of the cell, but also the energy consumption of the terminal device can be reduced. However, the present invention is not limited thereto, and for some downlink signals, the terminal device can receive them during the first period when the cell is in the first state and the second period when the cell is in the second state. In this way, the user experience can be ensured.

[0091] In some embodiments, the terminal device may receive a system broadcast, L1 / L2 common signal, or paging message from the cell during a second period in which the cell is in the second state, and may not receive a system broadcast, L1 / L2 common signal, or paging message from the cell during a first period in which the cell is in the first state.

[0092] In some embodiments, the terminal equipment may receive the terminal equipment dedicated signal from the cell during a second period in which the cell is in the second state, and may not receive the terminal equipment dedicated signal from the cell during a first period in which the cell is in the first state.

[0093] In these embodiments, the dedicated signal for the terminal device may include a PDCCH for scheduling HARQ initial transmission data for the terminal device, i.e., the terminal device receives HARQ initial transmission data only during the second period when the cell is in the second state.

[0094] In these embodiments, a terminal device supporting DRX (Discontinuous Reception) starts or restarts a Discontinuous Reception Start Timer (drx-onDurationTimer) when the following condition is met and the cell is in a second period: [(SFN×10)+subframe number] modulo (drx-ShortCycle)=(drx-StartOffset) modulo (drx-ShortCycle) where SFN is the system frame number, subframe number is the subframe number, drx-ShortCycle is the discontinuous reception period, and drx-StartOffset is the time offset within the discontinuous reception period; and A terminal device that supports DRX stops the drx-onDurationTimer timer when the second period ends.

[0095] In these embodiments, a terminal device supporting DRX receives a PDCCH for scheduling HARQ initial transmission data and starts or restarts a discontinuous reception inactivity timer (drx-InactivityTimer) when the cell is in the second period; and A terminal device that supports DRX stops the drx-InactivityTimer timer when the second period ends.

[0096] In these embodiments, the terminal device starts a random access contention resolution timer (ra-ContentionResolutionTimer) when the following conditions are met: the terminal device is transmitting a random access msg3 and the cell is in the second period; and When the second period expires, the terminal device stops the ra-ContentionResolutionTimer.

[0097] In some embodiments, if the terminal device receives a PDCCH for scheduling HARQ initial transmission data of the terminal device only in the second period, the terminal device can receive a PDCCH for scheduling HARQ retransmission data of the terminal device only in the second period when the cell is in the second state. That is, the dedicated signals of the terminal device include not only a PDCCH for scheduling HARQ initial transmission data of the terminal device but also a PDCCH for scheduling HARQ retransmission data of the terminal device. The terminal device receives these dedicated signals from the cell in the second period when the cell is in the second state, and does not receive these dedicated signals from the cell in the first period when the cell is in the first state.

[0098] In these embodiments, a terminal device supporting DRX starts a discontinuous reception downlink retransmission timer (drx-RetransmissionTimeDL) when the following conditions are met: the downlink HARQ round trip time timer (drx-HARQ-RTT-TimerDL) expires, the terminal device cannot correctly decode the HARQ data, and the cell is in the second period; and A terminal device that supports DRX stops the drx-RetransmissionTimeDL and / or the drx-HARQ-RTT-TimerDL when the second period ends.

[0099] In these embodiments, the terminal device supporting DRX starts the discontinuous reception uplink retransmission timer (drx-RetransmissionTimeUL) when the following condition is met: the uplink HARQ round trip time timer (drx-HARQ-RTT-TimerUL) expires and the cell is in the second time period; and A terminal device that supports DRX stops the drx-RetransmissionTimeUL timer when the second period expires.

[0100] For example, a UE that supports DRX may start or restart the Drx-onDurationTimer, drx-InactivityTimer, drx-RetransmissionTimeDL and drx-RetransmissionTimeUL only within the first period and stop these timers when the second period ends.

[0101] In some embodiments, when the terminal device receives a PDCCH for scheduling HARQ initial transmission data of the terminal device only within the second period, the terminal device may also receive a PDCCH for scheduling HARQ retransmission data of the terminal device within a first period in which the cell is in the first state and a second period in which the cell is in the second state, i.e., the terminal device receives a PDCCH for scheduling HARQ initial transmission data of the terminal device only within the second period, and receives a PDCCH for scheduling HARQ retransmission data of the terminal device within the first and second periods.

[0102] For example, a UE that supports DRX may start or restart the Drx-onDurationTimer and the drx-InactivityTimer only during the first period and stop these timers when the second period ends. The drx-RetransmissionTimeDL and drx-RetransmissionTimeUL may be started and restarted within the first and second periods.

[0103] 7 is a diagram illustrating HARQ initial transmission and retransmission data reception times according to an embodiment of the present invention, showing that HARQ initial transmission data is received only in the second period, and HARQ retransmission data is received in the first and second periods. As shown in FIG. 7, during the second period when the cell is in the second state, UE-1 and UE-2 can receive HARQ initial transmission data 701 and 702. During the first period when the cell is in the first state, when UE-2 has HARQ retransmission data 703, UE-2 can receive HARQ retransmission data in the second period. During the first period when the cell is in the first state, UE-1 and UE-2 do not receive HARQ initial transmission data 704 and 705.

[0104] However, the present invention is not limited to this, and the terminal device may receive a PDCCH for scheduling the HARQ initial transmission data of the terminal device and a PDCCH for scheduling the HARQ retransmission data of the terminal device within the first period and the second period.

[0105] In some embodiments, the terminal device receives a random access response (RAR) from the cell within a second period in which the cell is in the second state, and does not receive a random access response (RAR) from the cell within a first period in which the cell is in the first state.

[0106] In these embodiments, the terminal equipment starts the random access response reception timer when the following conditions are met: the random access msg1 or MsgA has been sent and the cell is in the second period; and When the second period expires, the terminal device stops the random access response reception timer.

[0107] For example, if RAR can be received only within the second period, the UE can initiate random access only within the second period, and the ra-ResponseWindow and msgB-ResponseWindow can be activated only within the second period.

[0108] However, the present invention is not limited to this, and the RAR may be received within the first period and the second period, in which case the UE can initiate random access within the first period and the second period, and the ra-ResponseWindow and msgB-ResponseWindow can be activated within the first period and the second period.

[0109] In some embodiments, CSI-RS measurements, radio resource management (RRM) measurements, radio link monitoring (RLM) or beam failure detection (BFD) are performed during a second period in which the cell is in the second state, and no radio resource management (RRM) measurements, radio link monitoring (RLM) or beam failure detection (BFD) are performed during a first period in which the cell is in the first state.

[0110] In these embodiments, reference signals (e.g., SS, CSI-RS, and DRS) may be received only within the second period, in which case the UE may perform CSI-RS measurements, RRM measurements, RLM, or BFD only within the second period.

[0111] However, the present invention is not limited to this, and reference signals (e.g., SS, CSI-RS and DRS) may be received within the first period and the second period, in which case the UE can perform CSI-RS measurement, RRM measurement, RLM or BFD within the first period and the second period.

[0112] Although the embodiments of the present invention have been described above as examples, the present invention is not limited to these, and appropriate modifications can be made based on the above-described embodiments. Furthermore, each of the above-described embodiments can be used alone, or two or more of the above-described embodiments can be used in combination.

[0113] As can be seen from the above embodiment, a terminal device can receive indication information for indicating a first state and a second state for downlink transmission of a cell to which the terminal device is connected or located, and can receive information from the cell based on the indication information. Since a cell can switch between different states for downlink transmission, energy overhead of a network device can be saved. Furthermore, since a terminal device connected to or visiting the cell can receive information from the cell based on the indication information for indicating the first state and the second state of the cell, when a cell switches between the first state and the second state, the terminal device does not need to be handed over to another cell, and the terminal device originally visiting the cell does not need to perform cell reselection. This avoids traffic interruption and an increase in the load level of the neighboring cell caused by transferring a terminal device in a cell to a neighboring cell in an energy saving state, and prevents a degradation of user experience when a cell enters an energy saving state.

[0129] In some embodiments, the second information is used to switch the configuration parameters of the terminal device to configuration parameters that support one or more combinations of a time domain energy saving state, a frequency domain energy saving state, a power domain energy saving state, and a spatial domain energy saving state.

[0130] In some embodiments, the first information is used to indicate a switch between a BWP supporting the first state of the cell and a BWP supporting the second state, and the second information is used to indicate a switch between a non-energy saving BWP of the cell and at least one BWP supporting an energy saving state.

[0131] In some embodiments, the first information and / or the second information is transmitted by a common signal on L1 or L2.

[0132] In some embodiments, the L1 common signal includes a PDCCH scrambled by a network energy saving indicator (NES-RNTI), and the L2 common signal includes a MAC control unit (CE) scheduled by the PDCCH scrambled by the NES-RNTI, wherein the NES-RNTI is broadcast and transmitted to the terminal device by the system.

Furthermore, each of the above-described embodiments can be used alone, or two or more of the above-described embodiments can be used in combination.

This avoids traffic interruption and an increase in the load level of the neighboring cell caused by transferring a terminal device in a cell to a neighboring cell in an energy saving state, and prevents a degradation of user experience when a cell enters an energy saving state.
