The technical solution of the embodiment of the present application can be applied to various communication systems, such as: Global System of Mobile communication (Global System of Mobile communication, GSM) system, Code Division Multiple Access (Code Division Multiple Access, CDMA) system, Wideband Code Division Multiple Access (Wideband Code Division Multiple Access, WCDMA) system, General Packet Radio Service (General Packet Radio Service, GPRS), Long Term Evolution (Long Term Evolution, LTE) system, LTE Frequency Division Duplex (Frequency Division Duplex, FDD) system, LTE Time Division Duplex (Time Division Duplex, TDD), Universal Mobile Telecommunications System (UMTS), Worldwide Interoperability for Microwave Access (WiMAX) communication system, the future fifth generation (5th Generation, 5G) system or new Wireless (New Radio, NR), etc.

The embodiment of the present application can also be applied to a distribution network including multiple nodes, and the nodes in the distribution network can communicate with the terminal device directly, or can communicate with the terminal device through multi-hop node forwarding.

The first device in this embodiment of the present application may refer to user equipment, access terminal, subscriber unit, subscriber station, mobile station, mobile station, remote station, remote terminal, mobile device, user terminal, terminal, wireless communication device, user agent or user device. The terminal device can also be a cellular phone, a cordless phone, a session initiation protocol (Session Initiation Protocol, SIP) phone, a wireless local loop (Wireless Local Loop, WLL) station, a personal digital processing (Personal Digital Assistant, PDA), a wireless communication function Handheld devices, computing devices or other processing devices connected to wireless modems, vehicle-mounted devices, wearable devices, terminal devices in the future 5G network or terminals in the future evolution of the Public Land Mobile Network (PLMN) Devices, stations (stations, STAs), etc. are not limited in this embodiment of the present application. For convenience of description, a station (station, STA) is taken as an example in the following embodiments for illustration.

The second device in the embodiment of the present application may be a device for communicating with the first device, and the first device may be a Global System of Mobile communication (GSM) system or a Code Division Multiple Access (Code Division Multiple Access, The base station (Base Transceiver Station, BTS) in CDMA) can also be the base station (NodeB, NB) in the wideband code division multiple access (Wideband Code Division Multiple Access, WCDMA) system, can also be the evolved base station in the LTE system (Evolutional NodeB, eNB or eNodeB), or a wireless controller in a cloud radio access network (Cloud Radio Access Network, CRAN) scenario, or the network device can be a relay station, an access point, a vehicle-mounted device, a wearable device As well as the network equipment in the future 5G network or the network equipment in the future evolved PLMN network, as well as the access point (AP), or the personal basic service set control point (English: Personalbasic service set Control Point, PCP), etc., this application implements Examples are not limited. For convenience of description, AP is taken as an example in the following embodiments for illustration.

Fig. 1 shows a schematic diagram of signal feedback in a traditional solution. As shown in FIG. 1 , signal transmission is performed between AP1 and STA1 in a quasi-static manner, that is, signals are periodically transmitted between AP1 and STA1 . If STA2 receives signal 1 sent by AP1 to STA1 and knows that the time domain resources of signal 1 are occupied, STA2 may send feedback information to AP2 to prevent AP2 from allocating time domain resources with interference to STA2.

Wherein, in the traditional solution, the time-domain resource structure of signal transmission is divided in units of SPs, and one SP includes multiple blocks of the same size, and the intervals between different blocks are the same. That is to say, when the starting position of Block1 is known, the starting position of Block2 can be determined from the size of the Block and the period of the Block. In this way, STA2 can carry the starting position of Block1 of the time-domain resource occupied by signal 1 in the feedback information, the size of the block, and the period of the block, and AP2 can determine the specific details of multiple Blocks occupied by signal 1 in the SP according to the feedback information. location, so as to avoid configuring the time domain resources occupied by signal 1 for STA2, that is, to avoid interference caused by signal 1 to signal 2.

Wherein, the quasi-static mode means that each SP has the same offset time for the target beacon transmission time (target beacon transmission time, TBTT), and the duration is the same.

FIG. 2 shows a manner of dividing time-domain resources according to an embodiment of the present application. In this manner, the time domain resource includes a first-level time period, the first-level time period includes at least one second-level time period, and each second-level time period in the at least one second-level time period includes a plurality of third-level time periods level period.

In a specific embodiment, the first-level period is a service period SP, the second-level period is a time division duplex time slot TDD Slot, and the third-level period is a time-division duplex service period TDD SP; As shown in 2, the time domain resource includes a service period SP, which can be divided into multiple TDD time slots (Slots), and each TDD slot can be divided into multiple TDD SPs. Specifically, the TDD Slot can be the same as the Block in the traditional solution.

In this application, there are no restrictions on the division of time-domain resources and the division names, and any division and division name that are substantially the same as those in this application fall within the scope of this application.

In a multi-hop backhaul network, if the time-domain resource required by a certain user exceeds the size of the block in the traditional solution, it can be realized by connecting multiple blocks in series. For example, as shown in Figure 3, the time intervals between Blocks can be connected, and time domain resources can be re-divided, that is, blocks can be re-divided into TDD Slots after being connected, and then TDD SPs can be further divided under each TDD Slot.

Therefore, the TDD Slot in the embodiment of the present application may have the same size as the Block in the traditional solution, or may be different from the Block in the traditional solution.

As shown in Figure 4, Figure 4 is a TDD Slot structural element representing the TDD Slot structure, and the AP can carry the TDD Slot structural element in a beacon frame or other frame and send it to the STA, so that the STA can obtain the division information of the TDD Slot .

As shown in FIG. 4 , the TDD Slot structure element may include an element ID field, an element length field, an element ID extension field, a TDD slot scheduling control field, a data block duration field, and a TDD slot scheduling field. Wherein, the TDD time slot scheduling control field includes the subfield of the number of TDD SPs included in each TDD Slot, the interval duration (xIFS) subfield between TDD Slots, the interval duration (yIFS) between uplink TDD SPs or between downlink TDD SPs ) subfield, and the interval length (zIFS) subfield between the uplink TDDSP and downlink TDD SP, the allocation identifier subfield, the effective duration subfield of the data block, and the reserved subfield; the TDD slot scheduling field includes Multiple duration TDD SP duration subfields of TDD SP duration for each TDD SP.

In addition, the TDD SPs in the TDD Slot can be sorted in number order, and the TDD SPs in the same sorting position in different TDD Slots can be allocated to different STAs. As shown in Figure 5, Figure 5 is a TDD SP scheduling element representing TDD SP scheduling, and the AP can carry the TDD SP scheduling element in a broadcast frame or other frames and send it to the STA, so that the STA can obtain TDDSP scheduling allocation information .

As shown in FIG. 5 , the mapping relationship between each TDD SP and STA is indicated through the mapping relationship between the TDD start time and the bitmap and the device ID in the TDD SP scheduling element.

That is to say, the TDD SP allocated to STA in a TDD Slot is not periodic. For example, as shown in Figure 6, TDD SP1 and TDD SP2 are allocated to STA 2 in TDD Slot k+2, and TDD SP3 is allocated to STA1 . The STA cannot report the current TDD SP status of a certain TDD Slot to the AP according to the feedback method in the traditional solution. The rationality of domain resource allocation and the improvement of communication efficiency.

It can also be said that the TDD SP allocated to STA in a TDD Slot is not periodic. For example, as shown in Figure 6, TDD SP1 in TDD Slot k+1 is allocated to STA 1, and TDD SP3 in TDD Slot k+2 It is allocated to STA1, and TDD SP1 in TDDSlot k+3 is allocated to STA 1. STA1 cannot report the current TDD SP situation to the AP according to the feedback method in the traditional solution. Therefore, a feedback method is urgently needed to enable the AP to know the current TDD SP occupancy of STA1, so as to improve the rationality of time domain resource allocation. and improve communication efficiency.

Fig. 7 shows a schematic flowchart of a method for reporting time-domain resource information according to an embodiment of the present application. The embodiments of the present application can be applied to a communication system that performs multi-level division of time domain resources. A manner of dividing the time domain resource into multiple levels may be: the time domain resource includes a first-level time period, the first-level time period includes at least one second-level time period, and each of the at least one second-level time period A second-level period includes multiple third-level periods.

In a specific embodiment, the first-level period is a service period SP, the second-level period is a time division duplex time slot TDD Slot, and the third-level period is a time-division duplex service period TDD SP; As shown in 2, the time domain resource includes a service period SP, which can be divided into multiple TDD time slots (Slots), and each TDD slot can be divided into multiple TDD SPs. Specifically, the TDD Slot can be the same as the Block in the traditional solution.

In this application, there are no restrictions on the division of time-domain resources and the division names, and any division and division name that are substantially the same as those in this application fall within the scope of this application.

Specifically, the at least one time division duplex time slot TDD Slot has the same structure, that is, the number of time division duplex service periods TDD SP included in a certain time division duplex time slot TDD Slot is the same as the number of time division duplex service periods TDD SP in other time division duplex time slots TDD Slot. The number of duplex service periods TDD SP is the same, and the duration of each time division duplex service period TDD SP included in a certain time division duplex time slot TDD Slot is the same as the corresponding time division duplex time period in other time division duplex time slot TDD Slots. The duration of the service period TDDSP is the same.

It should be noted that the service period SP may be a unit for the second device to allocate time domain resources for the service flow of the first device, for example, a service period (service period, SP) in a communication system composed of an AP and an STA, also It may be a unit that allocates time-domain resources for service data streams in other communication systems mentioned above, which is not limited in this application. In addition, the embodiment of the present application does not limit the name of the service period SP, time division duplex time slot TDD Slot and time division duplex service period TDD SP. Other names with the same function as TDD Slot and time-division duplex service period TDD SP are within the scope of protection of this application. For convenience of description, the following embodiments take SP, TDD Slot, and TDD SP as examples for illustration.

701. The first device determines information about at least one TDD SP that needs to be reported.

Specifically, the first device may measure information of at least one TDD SP that needs to be reported among multiple TDD SPs in at least one TDD Slot. The information of the TDD SP may be that the TDD SP is in an idle state or an occupied state; it may also be Whether the TDD SP is set with a network allocation vector (Network allocation vector, NAV), and in the case of setting the NAV, the duration of the set NAV; it can also be whether the interference time of the TDD SP is greater than the preset threshold, Or the specific interference time when it is greater than the preset threshold; it can also be whether the interference time ratio of a TDD Slot is greater than the preset threshold, or the specific interference time ratio in the case of greater than the preset threshold; it can also be The TDD SP prefers one or some STAs; it can also be whether the signal strength detected on the TDD SP is greater than the preset threshold, or the specific signal strength in the case of the preset threshold; it can also be at least two of the above combination etc.

Specifically, the request element or indication element may have only one bit, and if the bit is 1, it means that the first device needs to measure the information of the TDD SP, and if the bit is 0, it means that the first device does not need to measure the information of the TDD SP. For example, as shown in FIG. 8, the directional channel quality request (Measurement Request fieldformat for Directional Channel Quality request for the measurement request field format includes measurement classification (operating class), channel number (channel number), application identification (application) of the measurement user identifier, AID), a reserved field, and a measurement method (measurement method), wherein the reserved field can be used as a field of request information, so as to trigger the first device to send feedback information of the TDD SP.
