The embodiment of the application discloses a monitoring method of control information and a related product, wherein a terminal node determines the monitoring time of the control information according to a predefined rule or an indication signaling, the control information only needs to be monitored at the determined monitoring time, and monitoring is not needed to be carried out in each superframe, so that the power consumption of the terminal node can be reduced.

In order to better understand the monitoring method of control information and the related products disclosed in the embodiments of the present application, a network architecture suitable for the embodiments of the present application is described below. The method disclosed by the embodiment of the application can be applied to a Wireless Short-Range Communication System (Wireless Short-Range Communication System), such as a vehicle-mounted Wireless Short-Range Communication System (automatic Wireless Short-Range Communication System), and can also be applied to other Communication systems as long as a scene needing to monitor control information exists in the Communication System.

A network architecture to which the method disclosed in the embodiments of the present application is applicable will be described below.

Referring to fig. 1, fig. 1 is a schematic diagram of a network architecture according to an embodiment of the present application. The network architecture is suitable for scenes needing monitoring control information, and can be applied to vehicle-mounted communication (a vehicle-mounted wireless short-distance communication system) or home network communication and the like.

Wireless short-range communication is designed with the goal of low latency, low power consumption, etc., rather than high throughput, high rate, as is the case with current technologies such as WiFi. Wireless short-range communication does not use large bandwidth to achieve a very high throughput multimedia experience. In vehicle-mounted communication, wireless short-distance communication is mainly oriented to application scenes such as noise reduction, voice, screen projection and electronic keys.

The network architecture of the embodiment of the application is described by taking a vehicle-mounted wireless short-range communication system as an example. As shown in fig. 1, the network architecture includes a management Node (G Node) and a plurality of Terminal nodes (T Node), such as Terminal Node 1, Terminal Node 2, and Terminal Node 3 shown in fig. 1. The management node is used as a central node, and the terminal node can be in the forms of a telephone, a wearable device, a camera, a screen, a sound, a sensor and the like. Some types of end nodes are those that require power saving or energy saving. In order to save energy, it is generally necessary to use a burst (burst) transmission method, for example, to distinguish between a connected state and an idle state, and to use Discontinuous Reception (DRX).

The vehicle-mounted wireless short-distance communication system can be applied to vehicle-mounted equipment, and comprises a system for interconnection and communication among a cabin area controller, a vehicle-mounted terminal (such as vehicle-mounted audio equipment, vehicle-mounted video equipment and an anti-theft system), a smart phone and intelligent wearing equipment.

The management node is a node for sending data scheduling information in the vehicle-mounted wireless short-distance communication system, and the terminal node is a node for receiving the data scheduling information and sending data according to the data scheduling information in the vehicle-mounted wireless short-distance communication system.

A Communication link for transmission from the Node to the Terminal Node (referred to as a "G link") may be referred to as a "G link" for short, and may carry a data channel, a control channel, a broadcast channel, a synchronization signal, and the like from the management Node to the Terminal Node.

A Communication link for transmission from a Terminal Node to a management Node (hereinafter referred to as "T link") may be referred to as a "T link", and the T link may carry a data channel, an access channel, and the like from the Terminal Node to the management Node.

In order to better understand the vehicular wireless short-range communication system, some terms that may be used in the vehicular wireless short-range communication system are defined below.

The management Node Symbol (Symbol for transmission from the Grant Node to the Terminal Node) is a Cyclic Prefix Orthogonal Frequency Division Multiplexing (CP-OFDM) Symbol carrying transmission from the management Node to the Terminal Node, and may also be referred to as a G Symbol.

A Terminal Node Symbol (Symbol for transmission from Terminal Node to Grant Node) is a CP-OFDM Symbol carrying transmission from a Terminal Node to a management Node, and may also be referred to as a T Symbol.

A Communication Domain (Communication Domain) is a resource of a G link and a T link of one management node in a vehicle-mounted wireless short-distance Communication system. On one carrier used by a G node, a resource set consisting of resources for transmitting synchronization signals, broadcast information, G link control information, and resources that the G node can schedule and configure is called a communication domain of the G node, and the G node is called a G node of the communication domain.

A Super Frame (Super Frame) is a time length composed of 48 wireless frames in the in-vehicle wireless short-range communication system. The 1 superframe is 48 radio frames 1 millisecond (ms) 384 symbols.

A Half superframe (Half Super Frame) is a time length formed by 24 wireless frames in the vehicle-mounted wireless short-distance communication system.

The First Synchronization Signal (FSS) is a Signal used for time and frequency Synchronization in the vehicle-mounted wireless short-range communication system, and one set of two Synchronization signals is a Synchronization Signal that appears First in the time domain.

The Second Synchronization Signal (SSS) is a Signal used for time and frequency Synchronization in the vehicle-mounted wireless short-range communication system, and is a set of two Synchronization signals, which appear later in time.

The Phase Adjustment Signal (PAS) is a Signal used for Phase Adjustment in the in-vehicle wireless short-range communication system.

A High Level Communication Domain (High Level Communication Domain) is a resource used by a G node of a High Level Communication Domain to transmit a general Communication Domain in a multi-Communication Domain scenario.

In a multi-Communication Domain scenario, a general Communication Domain (Normal Level Communication Domain) is a general Communication Domain G node that receives resources of a general Communication Domain sent by a G node of a higher Level Communication Domain and generates a general Communication Domain according to the resources.

A Physical Layer Identity (PID) is an Identity for Physical Layer addressing.

In the vehicle-mounted communication, the G link control information is control information transmitted from a G node (management node) to a T node (terminal node). The transmission resources of the G-link control information include common resources and T-node specific resources. For simplicity, the subsequent G-link control information is simply referred to as control information.

The control information common resource is indicated by broadcast information. The broadcast information may indicate the number of radio frames N or the number of symbols N of the control information common resource. The control information common resource uses the last system overhead symbol (G symbol) in each radio frame in N consecutive radio frames from the radio frame immediately after the radio frame transmitting the second synchronization signal in the super frame.

The control information T node specific resources are indicated by high layer signaling "T node specific control information resource pool set" and/or "T node specific control information resource pool". A T node specific control information resource pool set comprises one or more T node specific control information resource pools, e.g. up to 8. A T node specific control information resource pool comprises a set of resources for control information transmission belonging to a system overhead resource pool, the set of resources being indicated by a bit sequence (bitmap) of length 96, wherein a bit position set to 1 in the bit sequence indicates a position of a symbol used by the set of resources within the system overhead resource pool. The overhead resource pool has a maximum of 96 symbols.

The overhead resource pool is configured by high layer signaling overheadtimeresourcepoool. Wherein OverheadTimeResourcePool is an integer from 0 to 15.

When the overhead configuration period is 24 radio frames, the number of symbols in the overhead resource pool is (OverheadTimeResourcePool +1) × 3. When the overhead configuration period is 48 radio frames, the number of symbols in the overhead resource pool is (OverheadTimeResourcePool +1) × 6.

When the overhead configuration period is M radio frames, the first radio frame of each configuration period satisfies mod (radio frame number, M) equal to 0. When the number of symbols configured in one configuration period is N, an integer quotient of N divided by M is X, and a remainder is Y, then the configuration period is from 1 st radio frame to Y th radio frame, each radio frame includes (X +1) overhead symbols, and from (Y +1) th to M th radio frames, each radio frame includes X overhead symbols. The initial radio frame symbol configuration information indicated by the broadcast information indicates that the initial configuration in one radio frame is X G symbols and Y T symbols, and for the radio frame containing Z overhead symbols, all symbols in the radio frame are sequentially composed of (X-Z) G symbols, Z overhead symbols and Y T symbols which can be used for service data transmission. The first guard interval follows the overhead symbol when the overhead symbol is a G symbol, and precedes the overhead symbol when the overhead symbol is a T symbol.

In 48 wireless frames, the total number of symbols of the system overhead resources is 96 at most, and the symbols are numbered from 0 in sequence according to the time sequence in 48 wireless frames.

The control information common resources and control information T node specific resources defined above are both within one superframe. Typically, the end node will monitor the control information in each superframe by default, which results in a large power consumption of the end node.

Since broadcast type messages, such as system information (system messages), paging messages, etc., are not delay sensitive, the management node does not need to transmit once per superframe, nor does the end node need to receive once per superframe. In addition, the average packet arrival rate of some unicast-type services is low, and for these services, the management node does not need to schedule once per superframe, nor does the terminal node need to monitor once per superframe for scheduling. How to configure the monitoring time of the control information is an urgent problem to be solved.

Referring to fig. 2, fig. 2 is a flowchart illustrating a method for monitoring control information according to an embodiment of the present disclosure. As shown in fig. 2, the flow diagram may include the following steps.

And 201, the terminal node determines the monitoring time of the control information according to a predefined rule or an indication signaling.

In the embodiment of the present application, the predefined rule may define that the listening is performed in one or several superframes. For example, it is defined that a superframe listens to control information for scheduling system information, or a superframe listens to control information for scheduling paging messages. Wherein the predefined rules may be defined in a specification or standard, the management node and the end node following the same predefined rules when implemented.

The indication signaling can be from broadcast information or system information sent by a management node, and can also be from high-layer signaling. And for the unicast service, monitoring the control information sent by the management node at the monitoring time according to the monitoring time indicated in the indication signaling.

The control information may include various types of control information such as second-type data information transmission overhead resource indication information, control information for scheduling system information, control information for scheduling paging messages, and the like.

The listening occasions may include periodic listening occasions or aperiodic listening occasions. For the periodic monitoring opportunity, monitoring is performed once every fixed monitoring period, and when the monitoring period is not changed, the time interval between any two adjacent monitoring opportunities is equal. For aperiodic listening occasions, the time interval between any two neighboring listening occasions is not necessarily equal. For a periodic listening opportunity, the management node may configure a listening period and an offset in the listening period, and accordingly, the terminal node only listens for the control information in a superframe at the offset in the listening period.

The terminal node may be configured with a Discontinuous Reception (DRX) function to implement Discontinuous monitoring of the terminal node on control information (e.g., G link control information), so as to achieve the purpose of reducing power consumption of the terminal node.

Optionally, the listening time is configured by a period and an offset.

In this embodiment, the granularity of the period may be any one of a superframe, a radio frame, or a symbol, and the granularity of the offset may also be any one of a superframe, a radio frame, or a symbol. For example, taking the granularity of the period and the offset as superframes, if the period is 100 superframes and the offset is 10 superframes, the monitoring time is the 10 th superframe of each period, that is, the terminal node monitors in the 10 th superframe of each period, and does not need to monitor other superframes in the period, thereby reducing the power consumption of the terminal node.

In a possible embodiment, the period is M superframes, the offset is N superframes, M is an integer, and N is an integer.

The period may be in a superframe-minimum unit, and the offset may be in a superframe-minimum unit.

Wherein M is greater than N. For example, if M is 4, N may be 0, 1, 2, 3.

In this embodiment of the present application, the period and the offset may be defined by remainder or modulo operation, that is, the hyper-frame number X corresponding to the monitoring opportunity needs to satisfy X divided by M remainder as N. The remainder of dividing X by M is N, which can also be called X modulo (modulo or mod) M is N, or X modulo M is N.

Optionally, the listening opportunity may also be configured by a period, an offset, and a repetition period.

In the embodiment of the present application, the granularity of the repetition period may be any one of a superframe, a radio frame, or a symbol. For example, taking the granularity of the period, the offset and the repetition period as superframes as an example, if the period is 100 superframes, the offset is 10 superframes, and the repetition period is 10 superframes, the monitoring time is 10 th and 10 consecutive superframes of each period, that is, the terminal node can start to continuously monitor 10 superframes at the 10 th superframe of each period, and the data contents of the control information schedules monitored in the 10 consecutive superframes are consistent, so that the terminal node can obtain 10 versions of data, combine the data, improve the signal-to-noise ratio, and increase the reception reliability. The repetition period is suitable for broadcast type message transmission because multiple identical versions can be transmitted. In the unicast service, the repetition period may be duration (duration), and at this time, in the duration, the terminal node may monitor a plurality of continuous superframes corresponding to the duration, but data contents of the control information schedule monitored by the plurality of continuous superframes may be inconsistent, so that although the terminal node cannot be merged, the terminal node may monitor for a plurality of times, and may obtain more scheduling opportunities. The duration is suitable for unicast traffic.

In one possible embodiment, the repetition period is R superframes, and R is an integer.

The repetition period may be a minimum unit in a superframe.

Wherein, R is less than or equal to M, namely, the superframe number of the repeating period is less than or equal to the superframe number of the period. For example, if M is 4, N may be 0, 1, 2, 3, and R may be 2.

In this embodiment of the present application, the period and the offset may be defined by remainder or modulo operation, that is, the starting hyper-frame number Y corresponding to the monitoring opportunity needs to satisfy Y divided by M remainder as N. The remainder of dividing Y by M is N, which can also be called Y modulo (modulo or mod) M is N, or Y modulo M is N.

In the embodiment of the present application, the change period of the broadcast information may be understood as that the content of the broadcast information is kept unchanged in one change period. The period of change of the broadcast information may also be referred to as a period of the broadcast information. In some scenarios, the period of the broadcast information may also be different from the period of the change of the broadcast information.

When the management node restarts or the parameters are adjusted, the content of the broadcast information changes, so that the terminal node can only assume that the content of the broadcast information does not change in the broadcast information change period, and the terminal node can combine a plurality of received signals of the broadcast information in the broadcast information change period to increase the signal-to-noise ratio and successfully decode.

In the embodiment of the present application, the period of the broadcast information or the modification period may be predefined by the terminal node. The terminal node can monitor through a predefined period without receiving broadcast information for indication, so that signaling overhead can be saved. Wherein, L can be any one of 512, 1024, 2048 and 4096. In some scenarios, L may also be any of 40, 80, 160, 320.

In the embodiment of the present application, the period or the change period of the broadcast information may be indicated by the broadcast information sent by the management node. Before the terminal node is not connected with the management node, the terminal node can blindly detect the broadcast information and acquire the change cycle or period of the broadcast information according to the detected broadcast information so as to obtain the cycle of the monitoring opportunity, so that the cycle of the monitoring opportunity is always consistent with the change cycle or period of the broadcast information, the condition of monitoring missing of control information cannot occur, the condition of monitoring for multiple times cannot occur, and the power consumption of the terminal node is reduced. Wherein, L can be any one of 512, 1024, 2048 and 4096.

In this embodiment, the system information may include a G-link system message (which may be referred to as a system message for short), and is mainly used to carry a communication domain system message. In the embodiment of the present application, the system information and the system message are not distinguished, and the two are equivalent. When the T node is powered on, selects a connection, or indicates that the communication domain broadcast information or the system message is changed, it needs to execute an acquisition procedure of the communication domain system message.

The system information may also have a modification period, i.e. a period during which the content of the system information remains unchanged. The change period of the system information may also be referred to as a period of the system information. In some scenarios, the period of the system information may also be a different change period than the system information.

When the management node restarts or the parameters are adjusted, the content of the system information changes, so that the terminal node can only assume that the content of the system information is unchanged in the system information change period, and the terminal node can combine a plurality of received signals of the system information in the system information change period to increase the signal-to-noise ratio and successfully decode.

The change cycle of the system information may be the same as or different from the change cycle of the broadcast information.

In this embodiment, the period or the change period of the system information may be predefined by the terminal node. The terminal node can monitor through a predefined period without receiving system information for indication, so that signaling overhead can be saved. Here, K may be any one of 80, 160, and 320.

If the period of the system information is 160 superframes, the period of the listening opportunity may be equal to any one of 80 superframes, 160 superframes, or 320 superframes. If the period of the monitoring opportunity is equal to 80 superframes and the period of the system information is 160 superframes, the time delay of the terminal node for acquiring the control information is small; if the period of the monitoring opportunity is equal to 320 superframes and the period of the system information is 160 superframes, the signaling overhead of the terminal node for acquiring the control information is low; if the period of the monitoring opportunity is equal to 160 superframes and the period of the system information is 160 superframes, the time delay for the terminal node to acquire the control information is moderate, and the signaling overhead is moderate.

In this embodiment of the present application, the period or the change period of the system information may be indicated by the terminal node receiving the system information sent by the management node. The terminal node can indicate the monitoring period according to the detected system information, so that the period of the system information can be accurately obtained. Here, K may be any one of 80, 160, and 320.

Optionally, the offset is 0.

In the embodiment of the present application, the offset is set to be 0, and the monitoring opportunity is the first superframe of each period.

Optionally, the offset is an offset of broadcast information.

The offset of the broadcast information comprises the offset of a broadcast information starting hyper frame number in a period of the broadcast information or the offset of the broadcast information starting hyper frame number in a change period of the broadcast information.

In this embodiment of the present application, the broadcast information start hyper frame number includes a hyper frame number of a first super frame in consecutive 4 super frames of the broadcast information indicated in the broadcast information.

Broadcast information usage # N_sfSuperframe (N)_sfI.e., the starting superframe number) of 4 consecutive superframes using 2 overhead symbols, respectively # N, for each superframe_offsetLast overhead symbol sum # (N) in radio frame_offset+1) last overhead symbol in radio frame, where # N_sfIs a multiple of 4, N_offsetAnd sending through broadcast information. N is a radical of_offsetIs the starting radio frame number of the broadcast message.

Optionally, the offset is an offset of the broadcast information plus 4.

Broadcast information usage # N_sfThe 8 overhead symbols of 4 consecutive superframes are transmitted at the beginning of the superframe, and each superframe uses 2 overhead symbols, respectively # N_offsetLast overhead symbol sum # (N) in radio frame_offset+1) last overhead symbol in radio frame, where N_sfIs a multiple of 4, N_offsetAnd sending through broadcast information. Since the offset is the offset of the broadcast information plus 4, the listening opportunity will start from the superframe immediately after the last superframe of the broadcast information.

In the embodiment of the application, the monitoring opportunity adopts the monitoring opportunity of the control information for scheduling the system information, and the control information for scheduling the system information can be monitored at the monitoring opportunity.

In the embodiment of the present application, the scheduling paging message may define a paging occasion or a paging frame to monitor the control information for scheduling the paging message.

In the embodiment of the application, the resources of the first type of monitoring opportunity and the second type of monitoring opportunity in one superframe are staggered, so that the terminal node can selectively monitor different control information or resources of different control information in one superframe, and compared with the period and offset of the superframe level, the whole superframe is monitored, and power consumption caused by excessive monitoring of the terminal node is avoided.

The first type of listening occasion uses at least one radio frame and the second type of listening occasion uses at least one radio frame.

In the embodiment of the present application, the first-type monitoring opportunity is set to start from a radio frame immediately after a radio frame that transmits the second synchronization signal, and monitoring may be performed immediately after synchronization is completed. The first type of monitoring opportunity is adjacent to the second type of monitoring opportunity, so that the monitoring opportunities are prevented from being dispersed, the monitoring can be carried out in a centralized manner, and the monitoring efficiency is improved.

In the embodiment of the application, the second type of monitoring opportunity is set to start from the radio frame immediately after the radio frame sending the second synchronization signal, monitoring can be performed immediately after synchronization is completed, and the monitoring opportunity can be quickly determined by taking the second synchronization signal as a reference. The first type of monitoring opportunity is adjacent to the second type of monitoring opportunity, so that the monitoring opportunities are prevented from being dispersed, the monitoring can be carried out in a centralized manner, and the monitoring efficiency is improved.

In the embodiment of the application, the second-type data information transmission overhead resource indication information is sent by using the common resource of the control information. The second type data information transmission overhead resource indication information sent in the nth superframe indicates resources not used for transmitting the second type data in the (N +1) th superframe.

In the embodiment of the present application, the dynamic scheduling data control information is control information for scheduling system information/paging messages.

Referring to fig. 3, fig. 3 is a physical resource map of a first synchronization signal/a second synchronization signal/broadcast information/control information according to an embodiment of the present application.
