For example, Intelligent Reflective Surface (IRS) is based on the classical concept of reconfigurable reflectarray, in particular, IRS is an elementary Surface consisting of a large number of tiny elements that diffusely reflect an incident signal in a controlled manner.
The super-surface is applied to a communication system, and a base station controls parameters such as the phase of the super-surface to better control a diffuse reflection incident signal to realize controllable propagation of electromagnetic waves in a communication channel so as to improve the performances of the communication system in the aspects of coverage, capacity, energy efficiency and the like. The super-surface can realize controllable propagation of a plurality of phase changes, and when the super-surface is deployed in a wireless communication system, an appropriate reflection coefficient needs to be designed to obtain the optimal performance gain. The calculation of the optimal reflection coefficient of the super-surface is related to the channel state information, and the optimal reflection coefficient is usually configured after channel estimation is completed, so that the base station needs to firstly obtain the channel information from the base station to the super-surface and from the super-surface to the terminal, then the super-surface is controlled to adjust the phase of the signal of the base station according to the optimal reflection coefficient after the optimal reflection coefficient is calculated according to the channel state information, and the maximum gain of the system is obtained. If the super-surface can be equipped with a Radio Frequency (RF) chain, the super-surface element is partially or completely connected to the RF chain, and the channel estimation can be estimated at the base station, this involves three different operation modes of the super-surface device, one operation mode is that the super-surface element is in an active state to receive data, one operation mode is that the super-surface element is in an active state to transmit data, and the third operation mode is that the super-surface is in a passive transmission state, where the super-surface can controllably propagate the signal of the wireless electromagnetic wave. Since the super surface is an entity newly introduced into the communication system, signaling is required to indicate the operating mode of the super surface device.

Detailed Description
In order to make the objects, technical solutions and advantages of the present application more apparent, the technical solutions of the present application will be described in detail and completely with reference to the following specific embodiments of the present application and the accompanying drawings. It should be apparent that the described embodiments are only some of the embodiments of the present application, and not all of the embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present application.
The technical solutions provided by the embodiments of the present application are described in detail below with reference to the accompanying drawings.
Fig. 1 is a schematic diagram of an IRS enhanced multi-antenna wireless communication system.
IRS is a passive device, similar to a dish antenna used in satellite receivers, that reflects signals to improve signal-to-noise ratio. The different phase-shifted modes of its different element surfaces cause the incident signal to be reflected as a beam in different directions. IRS is a complement to traditional massive MIMO technology, unlike massive MIMO systems and cooperative relaying, although IRS also attempts to improve propagation conditions by deploying active hardware components, IRS requires only little operating power and is therefore suitable for implementation in energy-limited systems. Furthermore, IRS can naturally operate in full duplex without the need for costly self-interference cancellation. Furthermore, IRS is a very thin material that can be deployed on building facades and interior walls. Thus, once a legacy network is deployed, one or more IRSs can be flexibly deployed to mitigate detected coverage holes, or to provide additional capacity in areas where needed.
The deployment of intelligent meta-surfaces in conventional MIMO systems facilitates two types of beamforming, as shown in fig. 1, where an IRS is deployed in a system to facilitate communication between a multi-antenna transmitter and a user. An information signal is radiated from the transmitter and a direct path for communication may exist between the transmitter and the user, while the IRS also receives the information signal and will reflect the signal, with the infrared controller, the primary direction of the reflected signal can be controlled. In particular, appropriate phase shifts are introduced on all the element atoms to deliberately create a coherent combination of their respective scattered signals to produce a signal beam focused on the user, the larger the surface, the narrower the beam, a strategy known as energy focusing.
On the other hand, if there is no direct path due to severe shadowing or blockage, the transmitter should beam-form the IRS. The IRS may then act as a non-amplified full duplex relay, reflecting and focusing the signal to the end device UE to assist end-to-end communication. In fig. 1, consider a scenario where a multi-antenna transmitter serves user 1 in the presence of user 2. Assume that the two UEs have different security levels where the user 1 message cannot be decoded on user 2. In this case, by adjusting the phase of the scattered signal to stop the signal at the user 2, a destructive reflection can be made at the IRS, a strategy known as energy nulling.
Using these two principles, the irs is expected to have wide application in various communication systems, including interference management, coverage extension, and capability improvement, such as wireless communication systems, cognitive radio networks, physical layer security systems, and the like.
The intermediate device of the present invention controls propagation of electromagnetic waves in a communication channel by reflection, transmission, or the like to improve the performance of the communication system, and is not limited to the use of the IRS technology.
Fig. 2 is an embodiment of a method flow of an embodiment of the present application.
The embodiment of the application provides a method for indicating node transmission state signaling in a wireless communication system, wherein the wireless communication system comprises network equipment, intermediate equipment and user equipment, a service signal generated by the network equipment is received by the user equipment after passing through the intermediate equipment, and the method comprises the following steps:
step 101, determining the transmission state of the intermediate device and the indication information of the occupied time period of the intermediate device, wherein the indication information is contained in a downlink control signaling;
the transmission state includes: a first state, a second state, and a third state occurring in order within each complete duty cycle; the first state is an activated receiving state, the second state is an activated sending state, and the third state is a passive transmission state; the smallest particle of the occupied time period is a symbol;
the first state working period and the second state working period comprise a plurality of time slots and/or symbols. Preferably the period between at least one of the first and second state operating periods comprises no less than a set duration, e.g. a set number of symbols or time slots. Where the resource allocation is represented by the number of slots and the number of symbols.
The downlink control signaling comprises at least one of the following signaling: semi-static cell dedicated control signaling, semi-static node dedicated control signaling, and dynamic control signaling.
The cell dedicated control signaling of the present application refers to control signaling shared by wireless communication devices in a cell;
the node-specific control signaling of the present application refers to control signaling dedicated to the intermediate device.
And further, when the state information indicated by the semi-static signaling and the dynamic control signaling which indicate the special intermediate equipment conflicts, the priority indicated by the dynamic control signaling is higher.
Step 102, when the control signaling is a semi-static cell dedicated control signaling, the control signaling indicates: the first state time slot, the first state symbol, the second state time slot, the second state symbol, the first cycle, the second cycle, and the third cycle, where the first cycle is a total cycle of controlling the intermediate device to be in an active reception state and an active transmission state, and the second cycle is a cycle of controlling the intermediate device to be in a third state (a passive transmission state); the third cycle is the total cycle of the operation of the intermediate device, including the active state and the passive transmission state. That is, the period of the second cycle is the period of the third cycle minus the period of the first cycle. The first state symbol number is the symbol number which is continuously in the first state from the starting symbol, and the second state symbol number is continuously in the second state from the ending symbol onward.
And 103, combining the semi-static cell dedicated control signaling with the semi-static node dedicated control signaling by the control signaling. The node-specific control signaling indicates a specific state configuration for the intermediate device, and the indicated minimum granularity is at a symbol level. Wherein the node-specific signaling indicates that the time slot in the first state or the second state is further indicated in the time slot not indicated by the cell-specific configuration, or that the number of symbols in the first state after the start time and the number of symbols in the second state before the end time of the time slot not indicated by the cell-specific configuration are further indicated.
And step 104, the control signaling is a combination of a semi-static cell dedicated control signaling and a node dedicated semi-static signaling, and then a dynamic control signaling, wherein the dynamic control signaling is a dynamic state indication of the intermediate equipment and indicates uplink and downlink symbol configuration of a time slot which is not indicated by cell dedicated configuration.
Step 105, the intermediate device receives a pilot or data signal from the base station or the terminal in the first state, and transmits channel state information, or the pilot signal, or the data signal to the base station or the terminal in the second state, wherein the transmission resource of the intermediate device and the transmission resource of the terminal are orthogonal.
For example, within the third period, the network device sends passively transmitted data in a third state after sending the control signal of the first period; the intermediate device completes the uplink and downlink pilot frequency transceiving process in the first period, and reflects/transmits the signal containing the downlink service data in the second period.
The following describes each downlink control signaling scheme in steps 102-104 in detail.
The downlink control signaling firstly includes a semi-static cell dedicated control signaling, and further may include at least one of a semi-static intermediate device node dedicated control signaling and a dynamic control signaling.
Scheme one, the downlink control signaling is a semi-static cell dedicated control signaling
Fig. 3 is a schematic diagram of a configuration duration of a semi-static cell dedicated control signaling, where when the downlink control signaling includes the semi-static cell dedicated control signaling, one scheme is as follows: the semi-static cell-specific configuration information (state-configuration-common) in the semi-static cell-specific control signaling includes the following parameters: the first slot number S1, the second slot number S2, the first symbol number C1, the second symbol number C2, the first period T1, and the second period T2 and/or the third period T3. The first period comprises the working time of the intermediate equipment in a first state and a second state; the second period includes a working time length of the intermediate device in a third state; the third period is the sum of the first period and the second period.
Further preferably, the "cell configuration first state duration" of the intermediate device includes S1 consecutive time slots at the beginning of the first period, and the "cell configuration second state duration" of the intermediate device includes S2 consecutive time slots before the end of the first period. Further, the cell of the intermediate device configures the first state duration, and further includes C1 consecutive symbols including the start symbol in the next slot at the end time of the S1 slots. Further, the cell of the intermediate device configures a second state duration, which further includes C2 consecutive symbols including an end symbol in a previous slot of the start time of the S2 slots.
The third cycle is the overall duty cycle of the intermediate device, including the states of active and passive transmission. The durations of the first, second and third periods are set with reference to the subcarrier spacing.
Wherein the slot number and the symbol number represent resource allocation, for example, the slot number (S1) of the first state represents the number of consecutive "cell configuration first state slots" starting in the first period of the configuration, and the common symbol number (C1) of the first state represents the number of consecutive "cell configuration first state symbols" after a plurality of consecutive said cell configuration first state slots. The number of slots of the second state (S2) indicates the number of consecutive "cell allocation second state slots" before the end of the first period of allocation, and the number of common symbols of the second state (C2) indicates the number of consecutive "cell allocation second state symbols" before a plurality of consecutive said cell allocation second state slots. Alternatively, the third status slot number is further included (S3). And continuous unconfigured time slots or symbols are contained between the last cell configuration first state symbol and the first cell configuration second state symbol, and the total length of the unconfigured time slots or symbols is greater than a set time length and is used for the protection time length between the uplink and the downlink. And within the second or third period, the network device sends the passively transmitted data in the third state after sending the control signal of the first period, the time of the intermediate device in the third state is the second period, and the period of the second period is the period of the third period minus the period of the first period.
Fig. 4 is a diagram of another embodiment of a semi-static cell-specific control signaling configuration duration. When the downlink control signaling comprises a semi-static cell dedicated control signaling, the other scheme is as follows: the semi-static cell dedicated control signaling comprises the following parameters: the first slot index, the second slot index, the first common symbol number C1, the second common symbol number C2, the first period T2, and the second period T2 and/or the third period T3. The first period comprises the working time of the intermediate equipment in a first state and a second state; and the second period comprises the working time of the intermediate equipment in the third state.
Further preferably, the cell of the intermediate device configures a first state duration including all timeslots indicated by the first timeslot index; and the cell of the intermediate equipment configures a second state duration which comprises all time slots indicated by the second time slot index. Further, the cell of the intermediate device configures the first state duration, and further includes C1 consecutive symbols including the start symbol in the next non-indexed time slot at the time of the end of the time slot indicated by the first slot index. Further, the cell of the intermediate device configures a second state duration, and further includes C2 consecutive symbols including an end symbol in a previous non-indexed time slot of the time slot start time indicated by the second time slot index.
For example, the cell-specific semi-static configuration signaling configures a first period, a second period, and/or a third period, a subcarrier interval, and indicates, for the access point AP, that a slot index in the first period of the intermediate device corresponds to the first state or the second state; at this time, the cell configuration first state duration and the cell configuration second state duration may alternately occur, for example, the first state Slot1 and the second state Slot2 which occur for the first time occur in sequence, and then the first state Slot 3 occurs; the method also comprises the steps that a first state symbol and a second state symbol configuration are contained between a first state time slot and a second state time slot which appear for the first time; when the last symbol sybl 1 in the continuous cell configuration first state duration and the first symbol sybl 2 in the continuous cell configuration second state duration contain continuous unconfigured time slots or symbols, the total length of the unconfigured time slots or symbols is greater than a set duration and is used for the protection duration between the uplink and the downlink. For the non-indicated slots, the number of symbols C1 indicating the transmission state of the slot in which the slot extends from the start symbol to the previous slot, and the number of symbols C2 indicating the transmission state of the slot in which the slot continues from the end symbol to the next slot.
Scheme two, the downlink control signaling is a control signaling special for a semi-static cell and a control signaling special for a semi-static intermediate equipment node
In any embodiment of the first aspect, further, the downlink control signaling includes semi-static node-specific control signaling.
Fig. 5 is a schematic diagram of a configuration duration of semi-static node-specific control signaling. The semi-static cell dedicated control signaling comprises the following parameters: the first slot number S1, the second slot number S2, the first symbol number C1, the second symbol number C2, the first period T1, and the second period and/or the third period. The first period comprises the working time of the intermediate equipment in a first state and a second state; and the second period comprises the working time of the intermediate equipment in the third state.
For example, the cell of the intermediate device configures a first state duration, which includes S1 consecutive slots at the beginning of the first period, or further includes C1 consecutive symbols including the starting symbol in the next slot at the end of the S1 slots. The cell of the intermediate device configures a second state duration, which includes S2 consecutive time slots before the end of the first period, or C2 consecutive symbols including an end symbol in a previous time slot of the start time of the S2 time slots.
And the semi-static node dedicated control signaling further configures time slots or symbols of a first state and a second state in the unconfigured time period of the semi-static cell dedicated control signaling.
Preferably, the semi-static node-specific control signaling includes a first state-specific slot index SN1 and a second state-specific slot index SN 2. Configuring a first state time length by a node of the intermediate equipment, wherein the first state time length comprises all time slots indicated by a first state special time slot index in a period of non-configuration of a semi-static cell special control signaling, and the first state time slots are configured by the node; and configuring a second state time length by the node of the intermediate equipment, wherein the second state time length comprises all time slots indicated by the second state special time slot index in the unconfigured time period of the semi-static cell special control signaling, and the second state time slots are configured by the node.
Preferably, the semi-static node-specific control signaling comprises a first special symbol number CN1 and a second special symbol number CN 2. The node of the intermediate device configures a first state duration, and further includes, in a time period in which the semi-static cell dedicated control signaling is not configured, 1 continuous symbols of CN including a start symbol after the end of configuring the first state duration by any section of cell, as the node configures the first state symbol. The node of the intermediate device configures a second state duration, and further includes, in a time period in which the semi-static cell dedicated control signaling is not configured, CN2 continuous symbols including an end symbol before any section of cell configures the second state duration, as the node configures the second state symbol.
For example, the cell-specific semi-static configuration state information is determined by the following parameters: the time slot number of the first state and the number of the common symbols of the first state, the time slot number of the second state and the number of the common symbols of the second state, the first period, the second period and/or the third period, and the subcarrier spacing. The node-specific control signaling indicates a specific state configuration for the intermediate device, and the indicated minimum granularity is at a symbol level. Wherein the node-specific signaling indicates that the slot of the non-indicated region is in the first state, or the slot in the second state, or indicates the number of symbols in the first state after the start of the slot of the non-indicated region or the number of symbols in the second state before the end of the slot.
At the moment, the cell configuration second state duration and the node configuration second state duration are connected with each other; the first state duration configured by the cell and the first state duration configured by the node are connected with each other. And when the first state duration and the second state duration contain continuous unconfigured time slots or symbols, the total length of the unconfigured time slots or symbols is greater than a set duration and is used for protecting the duration between the uplink and the downlink.
Fig. 6 is a diagram of another embodiment of a configuration duration of semi-static node-specific control signaling.
When the downlink control signaling comprises a semi-static cell dedicated control signaling, the other scheme is as follows: the semi-static cell dedicated control signaling comprises the following parameters: the first slot index, the second slot index, the first common symbol number C1, the second common symbol number C2, the first period, the second period and/or the third period. The first period comprises the working time of the intermediate equipment in a first state and a second state; and the second period comprises the working time of the intermediate equipment in the third state.
For example, the cell of the intermediate device configures a first state duration, which includes all slots indicated by the first slot index and C1 consecutive symbols including the start symbol in the next non-indexed slot at the time of the slot end indicated by the first slot index. The cell of the intermediate device configures a second state duration, which includes all slots indicated by the second slot index and C2 consecutive symbols including the end symbol in the previous non-indexed slot of the slot start time indicated by the second slot index.
And the semi-static node dedicated control signaling further configures time slots or symbols of a first state and a second state in the unconfigured time period of the semi-static cell dedicated control signaling.
For example, the semi-static node-specific control signaling includes a first state-specific slot index and a second state-specific slot index. Configuring a first state duration including all time slots indicated by a first state special time slot index in a period of non-configuration of a semi-static cell special control signaling by a node of the intermediate equipment; and configuring a second state duration by the node of the intermediate equipment, wherein the second state duration comprises all time slots indicated by the second state special time slot index in the unconfigured time period of the semi-static cell special control signaling.
As another example, the semi-static node-specific control signaling includes a first dedicated symbol number CN1 and a second dedicated symbol number CN 2. The node of the intermediate device configures a first state duration, and further includes, in a period in which the semi-static cell dedicated control signaling is not configured, 1 consecutive symbols of CN including a start symbol after any section of cell configures the first state duration. The node of the intermediate device configures the second state duration, and further includes, in a time period in which the semi-static cell dedicated control signaling is not configured, CN2 consecutive symbols including the end symbol before any cell configures the second state duration.
For example, the cell-specific semi-static configuration signaling configures a first period, a second period, and/or a third period, a subcarrier interval, indicates that a Slot index in the first period of the intermediate device corresponds to a first state for the AP, and indicates, for a Slot that is not indicated, a symbol number of a Slot in which the Slot is located that is consecutive from a start symbol to a previous first state Slot (e.g., Slot 1), or a symbol number of a Slot in which the Slot is located that is consecutive from an end symbol to a previous first state Slot (e.g., Slot 2). Furthermore, the node-specific control signaling indicates a specific state configuration for the intermediate device, and the indicated minimum granularity is at a symbol level. Wherein the node-specific signaling indicates that a portion of the time slots of the region not indicated by the cell-specific configuration are in a first state or a second state (e.g., indicating SN2 is in the second state), or that any time slot or symbol of the region not indicated by the cell-specific configuration lasts for the number of symbols of the previous time slot or symbol state, or that any time slot or symbol continues for the number of symbols of the next time slot or symbol state. For example, the node configuration first state symbol is consecutive in time with the cell configuration first state symbol (e.g., the first phase first state symbol C11 of the cell configuration and the first phase first state symbol CN11 of the node configuration are consecutive; the second phase first state symbol C12 of the cell configuration and the second phase first state symbol CN12 of the node configuration are consecutive); and between two continuous first state duration, a node configuration second state time slot SN2 is also included. And when the continuous first state duration and the continuous second state duration contain continuous unconfigured time slots or symbols, the total length of the unconfigured time slots or symbols is greater than a set duration and is used for protecting the duration between an uplink and a downlink.
In any of the above embodiments, further, the downlink control signaling includes dynamic control signaling, such as scheme three to scheme four:
the downlink control signaling is a semi-static cell dedicated control signaling and is combined with an intermediate equipment node dynamic control signaling;
for example, the cell-specific semi-static configuration signaling configures a first period, a second period, a subcarrier spacing, and cell-specific semi-static configuration status information, which further includes: the number of first-state slots, the number of first-state common symbols, the number of second-state slots, and the number of second-state common symbols, or, the slot index in the first period for indicating the intermediate device to the AP corresponds to the first transmission state or the second transmission state. And for the time slot which is not indicated, indicating the number of symbols of the transmission state of the time slot which is continued from the starting symbol to the previous time slot, and indicating the number of symbols of the transmission state of the time slot which is continued from the ending symbol to the next time slot.
The node dynamic control signaling is dynamic state indication of the intermediate equipment, indicates uplink and downlink symbol configuration of a time slot of a cell dedicated configuration non-indicated region, is scrambled by a newly defined RNTI of an intermediate equipment time slot format, and indicates information of a first state and a second state of a plurality of designated time slots of the intermediate equipment.
And the dynamic control signaling further configures time slots or symbols in a first state and a second state in the unconfigured time period of the semi-static cell dedicated control signaling.
Preferably, the dynamic control signaling comprises a first special symbol number CN1 and a second special symbol number CN 2. The node of the intermediate device configures a first state duration, which contains 1 continuous symbols of the CN including the starting symbol after the end of any section of "cell configures the first state duration" in the unconfigured time period of the semi-static cell dedicated control signaling. The node of the intermediate device configures a second state duration, which contains the CN2 continuous symbols containing the end symbols before any section of cell configuration second state duration begins in the unconfigured time period of the semi-static cell dedicated control signaling.
Preferably, the dynamic control signaling is scrambled by an RNTI of the intermediate device, and includes information indicating a state of any slot in the first period, including at least one of the following states of the any slot: all symbols are in a first state, all symbols are in a second state, some symbols are in a first state, and some symbols are in a second state.
And in the fourth scheme, the downlink control signaling is a semi-static cell dedicated control signaling and is combined with a semi-static intermediate equipment node dedicated control signaling and a dynamic control signaling.
For example, the cell-specific semi-static configuration signaling configures a first period, a second period, a subcarrier spacing, and cell-specific semi-static configuration status information, which further includes: the number of first-state slots, the number of first-state common symbols, the number of second-state slots, and the number of second-state common symbols, or, the slot index in the first period for indicating the intermediate device to the AP corresponds to the first transmission state or the second transmission state. And for the time slot which is not indicated, indicating the number of symbols of the transmission state of the time slot which is continued from the starting symbol to the previous time slot, and indicating the number of symbols of the transmission state of the time slot which is continued from the ending symbol to the next time slot.
For the area which is not indicated after the cell-specific indication still exists, the semi-static node-specific control signaling indicates the specific state configuration for the intermediate device, and the indicated minimum granularity is at a symbol level. Wherein the intermediate device-specific signaling indicates that a number of slots of the area not indicated by the cell-specific configuration are in the first state or the second state, or a number of consecutive symbols of the first state after a start time of any slot of the area not indicated, or a number of consecutive symbols of the second state before an end time of the slot of the area not indicated.
For the area which is not indicated after the cell dedicated indication still exists, the node dynamic control signaling is the dynamic state indication of the intermediate device, indicates the uplink and downlink symbol configuration of the time slot of the area which is not indicated by the cell dedicated configuration, and the dynamic control signaling is scrambled (interface-RNTI) by a newly defined RNTI of the intermediate device time slot format and indicates the information of the first state and the second state of the single time slot of the intermediate device.
Wherein the priority of the state configuration information dedicated to the cell is the highest, and secondly, when the area which is not indicated by the cell dedicated configuration information is indicated, the priority of the dynamic control signaling is higher than that of the semi-static node dedicated control signaling. That is, when the node configures the duration of the first state, and the dynamic control signaling indicates that any time slot or symbol is in the second state, then the any time slot or symbol is set to be in the second state; when the node configures the duration of the second state, and the dynamic control signaling indicates that any time slot or symbol is in the first state, the any time slot or symbol is set to be in the first state.

Step 203, in the time phase of the first period T1, the intermediate device is in the time slot or symbol of the second state, and the intermediate device is in the transmission state. An example of this is that the channel estimation information of the intermediate device (including the channel state information from the base station to the intermediate device and from the intermediate device to the terminal) is sent to the network device, for example, the intermediate device sends the uplink pilot signal to the base station, where the uplink resources of the intermediate device and the M terminals are orthogonal in time, frequency, space or sequence. The network device comprises the following steps: step 203A, in the time period occupied by the second state, receiving the channel state feedback information of the intermediate device or the uplink pilot signal from the intermediate device. An intermediate device comprising the steps of: step 203B, in the time period occupied by the second state, acquiring channel state information from the network equipment to the intermediate equipment and from the intermediate equipment to the user equipment, and sending the channel state information to the network equipment; or, the intermediate device transmits the uplink pilot signal in the second state period.
In step 204, the base station or AP is in the third state during the time period of the second period T3-T1. One example of the method is that the base station or the AP calculates information Θ for controlling the phase, amplitude, and the like of the intermediate device by using channel state feedback information from the intermediate node received in the time phase of the first period T1, and the base station or the AP sends downlink data to the terminal in the time phase of T3, or the terminal sends uplink data to the AP, and the data is subjected to signal adjustment through the control information Θ of the intermediate device. The network device comprises the following steps: step 204A, calculating and sending control information according to channel state information fed back by the intermediate equipment, wherein the control information is used for adjusting the phase and amplitude characteristics of a third state of the intermediate equipment; and transmitting downlink service data or receiving uplink service data in the time period occupied by the third state. An intermediate device comprising the steps of: step 204B, in the time period occupied by the third state, passively transmitting the downlink service data from the network device or the uplink service data from the user equipment. User equipment comprising the steps of: and step 204C, receiving downlink service data or sending uplink service data in the time period occupied by the third state.
