[0056] The embodiments of the present application disclose a method for monitoring control information and related products. The terminal node determines the monitoring time of the control information according to predefined rules or indication signaling. It only needs to monitor the control information at the determined monitoring time, and there is no need to monitor in each superframe, thereby reducing the power consumption of the terminal node.

[0057] In order to better understand the monitoring method and related products of the control information disclosed in the embodiment of the present application, the network architecture applicable to the embodiment of the present application is described below. The method disclosed in the embodiment of the present application can be applied to a wireless short-range communication system (Wireless Short-Range Communication System), such as an automotive wireless short-range communication system (Automotive Wireless Short-Range Communication System), and can also be applied to other communication systems, as long as there is a scenario in the communication system that requires monitoring of control information.

[0058] The following first introduces a network architecture applicable to the method disclosed in the embodiment of the present application.

[0059] See also Figure 1 , Figure 1 This is a schematic diagram of a network architecture provided by an embodiment of the present application. The network architecture is suitable for scenarios where monitoring control information is required, and the network architecture can be applied to vehicle-mounted communication (vehicle-mounted wireless short-range communication system) or home network communication, etc.

[0060] Compared with current technologies such as WiFi, the design goals of wireless short-range communication are low latency and low power consumption, rather than high throughput and high rate. Wireless short-range communication does not use large bandwidth to obtain a high-throughput multimedia experience. In vehicle-mounted communications, wireless short-range communication is mainly used for application scenarios such as noise reduction, voice, screen projection and electronic keys.

[0061] The network architecture of the embodiment of the application is described by taking a vehicle-mounted wireless short-range communication system as an example. Figure 1 As shown in FIG. 1 , the network architecture includes a management node (Grant Node, G node) and multiple terminal nodes (Terminal Node, T node), such as Figure 1 The terminal nodes 1, 2 and 3 are shown. The management node is the central node, and the terminal nodes can be in the form of phones, wearable devices, cameras, screens, speakers, sensors, etc. Some types of terminal nodes need to save power or energy (power saving). In order to save energy, it is generally necessary to adopt a bursty transmission mode, such as distinguishing between connected and idle states, using discontinuous reception (DRX), etc.

[0062] The vehicle-mounted wireless short-range communication system can be used for interconnection and communication between vehicle-mounted devices, including cockpit domain controllers, vehicle-mounted terminals (such as vehicle-mounted audio equipment, vehicle-mounted video equipment, anti-theft systems), smart phones, and smart wearable devices.

[0063] The management node is a node in the vehicle-mounted wireless short-range communication system that sends data scheduling information, and the terminal node is a node in the vehicle-mounted wireless short-range communication system that receives data scheduling information and sends data according to the data scheduling information.

[0064] The communication link for transmission from Grant Node to Terminal Node (Communication link for transmission from Grant Node to Terminal Node) can be referred to as "G link" for short. This link can carry data channels, control channels, broadcast channels, synchronization signals, etc. from the grant node to the terminal node.

[0065] The communication link for transmission from Terminal Node to Grant Node can be referred to as "T link" for short. This link can carry data channels, access channels, etc. from the terminal node to the grant node.

[0066] In order to better understand the vehicle-mounted wireless short-range communication system, some terms that may be used in the vehicle-mounted wireless short-range communication system are defined below.

[0067] The management node symbol (Symbol for transmission from Grant Node to TerminalNode) is a cyclic prefix orthogonal frequency division multiplexing (CP-OFDM) symbol that carries the transmission from the management node to the terminal node, and may also be referred to as a G symbol.

[0068] The terminal node symbol (Symbol for transmission from Terminal Node to GrantNode) is a CP-OFDM symbol that carries transmission from the terminal node to the management node, and may also be referred to as a T symbol.

[0069] The communication domain is the G link and T link resources of a management node in the vehicle-mounted wireless short-range communication system. On a carrier used by a G node, the resources that the G node sends synchronization signals, broadcast information, G link control information, and the resources that the G node can schedule and configure are called the communication domain of the G node, and the G node is called the G node of the communication domain.

[0070] A super frame is a time length composed of 48 radio frames in a vehicle-mounted wireless short-range communication system. 1 super frame = 48 radio frames = 1 millisecond (ms) = 384 symbols.

[0071] Half Super Frame is the time length consisting of 24 wireless frames in the vehicle-mounted wireless short-range communication system.

[0072] The first synchronization signal (FSS) is a signal used for time and frequency synchronization in the vehicle-mounted wireless short-range communication system. There are two synchronization signals in a group, and the synchronization signal that appears first in the time domain.

[0073] The second synchronization signal (SSS) is a signal used for time and frequency synchronization in the vehicle-mounted wireless short-range communication system. It is a group of two synchronization signals and is the synchronization signal that appears later in the time domain.

[0074] The Phase Adjustment Signal (PAS) is a signal used for phase adjustment in a vehicle-mounted wireless short-range communication system.

[0075] The High Level Communication Domain is a domain in which G nodes in a high level communication domain send resources used by a general communication domain in a multi-communication domain scenario.

[0076] The normal level communication domain is in a multi-communication domain scenario, where the normal level communication domain G node receives the resources of the normal level communication domain sent by the G node of the advanced communication domain, and generates the normal level communication domain based on the resources.

[0077] The physical layer identity (PID) is an identifier used for physical layer addressing.

[0078] In vehicle-mounted communications, G link control information is control information sent by a G node (management node) to a T node (terminal node). The transmission resources of the G link control information include public resources and T node specific resources. For simplicity, the subsequent G link control information is referred to as control information.

[0079] 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 of the N consecutive radio frames starting from the radio frame immediately after the radio frame in which the second synchronization signal is sent in the superframe.

[0080] The control information T-node specific resources are indicated by high-level 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 includes one or more T-node specific control information resource pools, for example, up to 8. A T-node specific control information resource pool includes a group of resources used for control information transmission, and the group of resources belongs to the system overhead resource pool. The group of resources is indicated by a bit sequence (bitmap) with a length of 96, wherein the bit position set to 1 in the bit sequence indicates the position of the symbol used by the group of resources in the system overhead resource pool. The system overhead resource pool has a maximum of 96 symbols.

[0081] The system overhead resource pool is configured through the high-level signaling OverheadTimeResourcePool, where OverheadTimeResourcePool is an integer from 0 to 15.

[0082] When the system overhead configuration period is 24 radio frames, the number of symbols in the system overhead resource pool is (OverheadTimeResourcePool+1)×3. When the system overhead configuration period is 48 radio frames, the number of symbols in the system overhead resource pool is (OverheadTimeResourcePool+1)×6.

[0083] When the system overhead configuration period is M radio frames, the first radio frame of each configuration period satisfies that mod(radio frame number, M) is equal to 0. When the number of symbols configured in a configuration period is N, the integer quotient of N divided by M is X, and the remainder is Y. Then, from the 1st radio frame to the Yth radio frame in the configuration period, each radio frame contains (X+1) overhead symbols, and from the (Y+1)th to the Mth radio frame, each radio frame contains X overhead symbols. The initial radio frame symbol ratio information indicated by the broadcast information indicates that the initial ratio in a radio frame is X G symbols and Y T symbols. For a radio frame containing Z overhead symbols, all symbols in the radio frame are composed of (XZ) G symbols that can be used for service data transmission, Z overhead symbols, and Y T symbols that can be used for service data transmission. When the overhead symbol is a G symbol, the first guard interval is after the overhead symbol, and when the overhead symbol is a T symbol, the first guard interval is before the overhead symbol.

[0084] Within 48 radio frames, the total number of system overhead resource symbols is up to 96, and the symbols are numbered sequentially from 0 according to the chronological order within the 48 radio frames.

[0085] The control information common resources and control information T-node specific resources defined above are all within one superframe. Generally, the terminal node will monitor the control information within each superframe by default, which will result in a large power consumption of the terminal node.

[0086] Since broadcast messages, such as system information (system messages) and paging messages, are not sensitive to latency, management nodes do not need to send them once per superframe, and terminal nodes do not need to receive them once per superframe. In addition, some unicast services have a low average packet arrival rate. For these services, management nodes do not need to schedule them once per superframe, and terminal nodes do not need to monitor scheduling once per superframe. How to configure the monitoring timing of control information is an urgent problem to be solved.

[0087] See also Figure 2 , Figure 2 FIG. 1 is a flow chart of a method for monitoring control information provided by an embodiment of the present application. Figure 2 As shown, the flowchart may include the following steps.

[0088] 201. The terminal node determines a monitoring timing of control information according to a predefined rule or an indication signaling.

[0089] In the embodiment of the present application, the predefined rules may be defined to monitor in one or more superframes. For example, it is defined to monitor control information for scheduling system information in a certain superframe, or to monitor control information for scheduling paging messages in a certain superframe. The predefined rules may be defined in a specification or standard, and the management node and the terminal node follow the same predefined rules when implementing them.

[0090] The indication signaling may come from broadcast information or system information sent by the management node, or may come from high-layer signaling. For unicast services, according to the monitoring opportunity indicated in the indication signaling, the control information sent by the management node is monitored at the monitoring opportunity.

[0091] The control information may include various types of control information, such as second-category data information transmission overhead resource indication information, control information for scheduling system information, control information for scheduling paging messages, and the like.

[0092] The listening opportunity may include a periodic listening opportunity or an aperiodic listening opportunity. For a periodic listening opportunity, the listening is performed once every fixed listening period. When the listening period remains unchanged, the time interval between any two adjacent listening opportunities is equal. For an aperiodic listening opportunity, the time interval between any two adjacent listening opportunities is not necessarily equal. For a periodic listening opportunity, the management node may configure the listening period and the offset within the listening period. Accordingly, the terminal node only listens to the control information within the superframe at the offset within the listening period.

[0093] The terminal node may be configured with a discontinuous reception (DRX) function to enable the terminal node to discontinuously monitor control information (eg, G link control information), thereby achieving the purpose of reducing power consumption of the terminal node.

[0094] In an embodiment of the present application, the terminal node determines the monitoring time of the control information according to a predefined rule or indication signaling, and only needs to monitor the control information at the determined monitoring time, without having to monitor in each superframe, thereby reducing the power consumption of the terminal node.

[0095] Optionally, the listening opportunity is configured by a period and an offset.

[0096] In the embodiment of the present application, 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 a superframe, if the period is 100 superframes and the offset is 10 superframes, the monitoring time is the 10th superframe of each period, that is, the terminal node monitors the 10th superframe of each period, and does not need to monitor other superframes in the period, thereby reducing the power consumption of the terminal node.

[0097] In a possible implementation manner, the period is M superframes, the offset is N superframes, M is an integer, and N is an integer.

[0098] The period may be in superframe as the smallest unit, and the offset may be in superframe as the smallest unit.

[0099] Wherein, M is greater than N. For example, if M=4, then N can be 0, 1, 2, or 3.

[0100] In the embodiment of the present application, the period and the offset can be defined by a remainder or modulo operation, that is, the superframe number X corresponding to the monitoring opportunity needs to satisfy that the remainder of X divided by M is N. The remainder of X divided by M is N, which can also be called X modulo (mod) M is N, or X modulo M is N.

[0101] Optionally, the monitoring opportunity may also be configured by a period, an offset and a repetition period.

[0102] In the embodiment of the present application, the granularity of the repetition period can be any one of a superframe, a wireless frame or a symbol. For example, taking the granularity of the period, the offset and the repetition period as a superframe, if the period is 100 superframes, the offset is 10 superframes, and the repetition period is 10 superframes, the listening opportunity is 10 superframes starting from the 10th of each period, that is, the terminal node can continuously listen to 10 superframes starting from the 10th superframe of each period, and the data content of the control information scheduling listened to in 10 consecutive superframes is consistent, so that the terminal node can obtain 10 versions of data, merge, 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 sent. In unicast services, the repetition period can be a duration (duration). At this time, within the duration, the terminal node can listen to multiple continuous superframes corresponding to the duration, but the data content of the control information scheduling listened to by these multiple continuous superframes can be inconsistent, so that although the terminal node cannot be merged, it can be listened to multiple times, and more scheduling opportunities can be obtained. The duration is suitable for unicast services.

[0103] In a possible implementation manner, the repetition period is R superframes, where R is an integer.

[0104] The repetition period may be in a superframe as the minimum unit.

[0105] Here, R is less than or equal to M, that is, the number of superframes in the repetition period is less than or equal to the number of superframes in the period. For example, if M=4, then N can be 0, 1, 2, 3, and R can be 2.

[0106] In the embodiment of the present application, the period and the offset can be defined by a remainder or modulo operation, that is, the starting superframe number Y corresponding to the listening opportunity needs to satisfy that the remainder of Y divided by M is N. The remainder of Y divided by M is N, which can also be called Y modulo (mod) M is N, or Y modulo M is N.

[0107] Optionally, the period is a period of broadcasting information or a period of changing information.

[0108] In the embodiment of the present application, the change period of the broadcast information can be understood as the content of the broadcast information remains unchanged within a change period. The change period of the broadcast information can also be called the period of the broadcast information. In some scenarios, the period of the broadcast information can also be different from the change period of the broadcast information.

[0109] When the management node is restarted or the parameters are adjusted, the content of the broadcast information will change. Therefore, the terminal node can only assume that the content of the broadcast information remains unchanged during the broadcast information change period. Therefore, the terminal node can merge the signals of multiple broadcast information received during the broadcast information change period to increase the signal-to-noise ratio and successfully decode.

[0110] Optionally, the period or change period of the broadcast information is a predefined number of L superframes, where L is an integer.

[0111] In the embodiment of the present application, the period or change period of the broadcast information may be predefined by the terminal node. The terminal node may monitor through the predefined period without receiving the broadcast information for indication, which may save signaling overhead. Among them, L may be any one of 512, 1024, 2048, and 4096. In some scenarios, L may also be any one of 40, 80, 160, and 320.

[0112] Optionally, the period or change period of the broadcast information is L superframes indicated by the broadcast information, where L is an integer.

[0113] In an embodiment of the present application, the period or change period of the broadcast information may be indicated by the broadcast information sent by the management node. Before the terminal node establishes a connection with the management node, the terminal node may blindly detect the broadcast information, and learn the change period or period of the broadcast information based on the detected broadcast information, thereby obtaining the period of the monitoring opportunity, so that the period of the monitoring opportunity is always consistent with the change period or period of the broadcast information, and there will be no situation where the control information is missed or multiple monitoring occurs, thereby reducing the power consumption of the terminal node. Wherein, L can be any one of 512, 1024, 2048, and 4096.

[0114] Optionally, the period is any one of 512 super frames, 1024 super frames, 2048 super frames, and 4096 super frames.

[0115] Optionally, the period is a period or a change period of system information.

[0116] In the embodiment of the present application, the system information may include a G link system message (which may be referred to as a system message), which is mainly used to carry the 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, connection selection, or indicates that the communication domain broadcast information or system message has changed, it is necessary to execute the communication domain system message acquisition process.

[0117] The system information may also have a change period, that is, 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 the period of the system information. In some scenarios, the period of the system information may also be different from the change period of the system information.

[0118] When the management node is restarted or the parameters are adjusted, the content of the system information will change. Therefore, the terminal node can only assume that the content of the system information remains unchanged during the system information change period. Therefore, the terminal node can combine the signals of multiple system information received during the system information change period to increase the signal-to-noise ratio and successfully decode.

[0119] The change period of the system information may be the same as or different from the change period of the broadcast information.

[0120] Optionally, the period or change period of the system information is a predefined K superframes, where K is an integer.

[0121] In the embodiment of the present application, the period or change period of the system information may be predefined by the terminal node. The terminal node may monitor at the predefined period without receiving the system information for indication, thereby saving signaling overhead. K may be any one of 80, 160, and 320.

[0122] If the period of system information is 160 superframes, the period of monitoring opportunity can be equal to any one of 80 superframes, 160 superframes or 320 superframes. If the period of monitoring opportunity is equal to 80 superframes and the period of system information is 160 superframes, the delay of terminal node obtaining control information is small; if the period of monitoring opportunity is equal to 320 superframes and the period of system information is 160 superframes, the signaling overhead of terminal node obtaining control information is small; if the period of monitoring opportunity is equal to 160 superframes and the period of system information is 160 superframes, the delay of terminal node obtaining control information is moderate and the signaling overhead is moderate.

[0123] Optionally, the period or change period of the system information is K superframes indicated by the broadcast information, where K is an integer.

[0124] In the embodiment of the present application, the period or 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 may indicate the monitoring period according to the detected system information, so as to accurately know the period of the system information. Among them, K may be any one of 80, 160, and 320.

[0125] Optionally, the period is any one of 80 super frames, 160 super frames, and 320 super frames.

[0126] Optionally, the offset is 0.

[0127] In the embodiment of the present application, the offset is set to 0, and the monitoring time is the first superframe of each cycle.

[0128] Optionally, the offset is an offset of broadcast information.

[0129] The offset of the broadcast information includes the offset of the start superframe number of the broadcast information in the period of the broadcast information or the offset of the start superframe number of the broadcast information in the change period of the broadcast information.

[0130] In the embodiment of the present application, the starting superframe number of the broadcast information includes the superframe number of the first superframe of the four consecutive superframes of the broadcast information indicated in the broadcast information.
