Technical Field

Background
In a distribution network, a time domain resource structure in which a transmitting end and a receiving end communicate is divided in units of Service Periods (SPs). In particular, the SP in turn comprises a plurality of blocks (blocks).
If STA1 and AP1 communicate in a quasi-static manner, signals are transmitted between AP1 and STA1 periodically. If STA2 receives the signal transmitted by AP1, STA2 may determine the block of SPs occupied by the next signal between STA1 and AP1 based on the frame format of the signal. In this case, STA2 may send feedback information to AP2 indicating block occupancy between STA1 and AP 1. AP2 may thus be configured with reasonable blocks to avoid signals between AP1 and AP1 from interfering with signals between AP2 and STA 2.
In current distribution networks, each block in the time domain resource structure can be further divided into a plurality of TDD SPs, and different TDD SPs can be used for different signal transmissions.

Detailed Description
The technical solution in the present application will be described below with reference to the accompanying drawings.
The technical scheme of the embodiment of the application can be applied to various communication systems, for example: a Global System for Mobile communications (GSM) System, a Code Division Multiple Access (CDMA) System, a Wideband Code Division Multiple Access (WCDMA) System, a General Packet Radio Service (GPRS), a Long Term Evolution (Long Term Evolution, LTE) System, an LTE Frequency Division Duplex (FDD) System, an LTE Time Division Duplex (TDD), a Universal Mobile Telecommunications System (UMTS), a Worldwide Interoperability for Microwave Access (WiMAX) communication System, a future fifth Generation (5G) System, or a New Radio Network (NR), etc.
The embodiment of the application can also be applied to a distribution network comprising a plurality of nodes, and the nodes in the distribution network can directly communicate with the terminal equipment or can communicate with the terminal equipment through forwarding of multi-hop nodes.
The first device in the embodiments of the present application may refer to a user equipment, an access terminal, a subscriber unit, a subscriber station, a mobile station, a remote terminal, a mobile device, a user terminal, a wireless communication device, a user agent, or a user equipment. The terminal device may also be a cellular phone, a cordless phone, a Session Initiation Protocol (SIP) phone, a Wireless Local Loop (WLL) station, a Personal Digital Assistant (PDA), a handheld device with Wireless communication function, a computing device or other processing device connected to a Wireless modem, a vehicle-mounted device, a wearable device, a terminal device in a future 5G Network or a terminal device in a Public Land Mobile Network (PLMN) for future evolution, a Station (STA), and the like, which are not limited in this embodiment. For convenience of description, the following embodiments take a Station (STA) as an example for illustration.
The second device in this embodiment of the present application may be a device for communicating with a first device, where the first device may be a Base Transceiver Station (BTS) in a Global System for Mobile communications (GSM) System or a Code Division Multiple Access (CDMA) System, may also be a Base Station (NodeB) in a Wideband Code Division Multiple Access (WCDMA) System, may also be an evolved NodeB (eNB or eNodeB) in an LTE System, may also be a wireless controller in a Cloud Radio Access Network (CRAN) scenario, or may be a relay Station, an Access Point, a vehicle-mounted device, a wearable device, and a Network device in a future 5G Network or a Network device in a future evolved PLMN Network, and an Access Point (AP), or a basic service set Control Point (Point), PCP), etc., the examples of the present application are not limited. For convenience of description, the following embodiments are described with reference to an AP as an example.
Fig. 1 shows a schematic diagram of signal feedback of a conventional scheme. As shown in fig. 1, signals are transmitted between AP1 and STA1 in a quasi-static manner, i.e., periodically between AP1 and STA 1. If STA2 receives signal 1 sent by AP1 to STA1 and knows that the time domain resource of signal 1 is occupied, STA2 may send feedback information to AP2 to avoid AP2 allocating the time domain resource with interference to STA 2.
In the conventional scheme, a time domain resource structure for signal transmission is divided by taking an SP as a unit, where one SP includes a plurality of blocks with the same size, and intervals between different blocks are the same. That is, knowing the starting position of Block1, the starting position of Block2 can be determined from the size of Block, and the period of Block. Therefore, STA2 may carry the start position of Block1 of the time domain resource occupied by signal 1 in the feedback information, the size of Block, and the period of Block, and AP2 may determine the specific positions of multiple blcoks occupied by signal 1 in SP according to the feedback information, thereby avoiding configuring the time domain resource occupied by signal 1 for STA2, i.e., avoiding interference caused by signal 1 to signal 2.
The quasi-static method means that offset times of each SP to a Target Beacon Transmission Time (TBTT) are the same, and durations thereof are the same.
Fig. 2 illustrates a manner of dividing time domain resources according to an embodiment of the present application. In this manner, the time domain resource includes first level periods including at least one second level period, and each of the at least one second level periods includes a plurality of third level periods.
In a specific embodiment, the first-stage time interval is a service time interval SP, the second-stage time interval is a time division duplex time Slot TDD Slot, and the third-stage time interval is a time division duplex service time interval TDD SP; as shown in fig. 2, the time domain resource includes a service period SP, which may be divided into a plurality of TDD slots (slots), each of which may be further divided into a plurality of TDD SPs. In particular, the TDD Slot may be the same as Block in the legacy scheme.
The present application does not limit the division of time domain resources and the division names, and any division and division name substantially the same as the present application fall within the scope of the present application.
In a multi-hop backhaul network, the size of a time domain resource required by a certain user exceeds the size of a Block in a traditional scheme, and the method can be realized by connecting a plurality of blocks in series. For example, as shown in fig. 3, the time intervals between blocks may be connected, and the time domain resources may be divided again, that is, Blcok is connected and then divided into TDD slots, and then TDD SPs are further divided under each TDD Slot.
Therefore, the TDD Slot in the embodiment of the present application may be the same as the Blcok size in the conventional scheme, or may be different from the Block in the conventional scheme.
As shown in fig. 4, fig. 4 is a TDD Slot structural element representing a TDD Slot structure, and the AP may carry the TDD Slot structural element in a beacon frame or other frames and send the beacon frame or other frames to the STA, so that the STA obtains division information of the TDD Slot.
As shown in fig. 4, the TDD Slot structure element may include an element (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. The TDD time Slot scheduling control field comprises a number subfield of TDD SPs included in each TDD Slot, an interval duration (xIFS) subfield between the TDD slots, an interval duration (yIFS) subfield between uplink TDD SPs or downlink TDD SPs, an interval duration (zIFS) subfield between the uplink TDD SPs and the downlink TDD SPs, an allocation identification subfield, a data block valid duration subfield, and a reserved subfield; the TDD Slot scheduling field includes a plurality of duration TDD SP duration subfields that represent a TDD SP duration for each TDD SP in the TDD Slot.
Furthermore, the TDD SPs in a TDD Slot may be ordered in the order of numbering, and TDD SPs in the same ordering position in different TDD slots may be allocated to different STAs. As shown in fig. 5, fig. 5 is a TDD SP scheduling element representing TDD SP scheduling, where the AP may carry the TDD SP scheduling element in a broadcast frame or other frames and send the broadcast frame or other frames to the STA, so that the STA obtains scheduling allocation information of the TDD SP.
As shown in fig. 5, the mapping relationship between the TDD start time and the bitmap and the device ID in the TDD SP scheduling element indicates the correspondence relationship between each TDD SP and the STA.
That is, TDD SPs allocated to STA in one TDD Slot are not periodic, for example, as shown in fig. 6, TDD SP1 and TDD SP2 are allocated to STA2 and TDD SP3 is allocated to STA1 in TDD Slot k + 2. The STA cannot report the situation of the current TDD SP of a certain TDD Slot to the AP according to a feedback manner in the conventional scheme, and therefore a feedback manner is urgently needed to enable the AP to know the occupation situation of the current TDD SP of a certain TDD Slot, so that the reasonability of time domain resource configuration is improved, and the communication efficiency is improved.
It can also be said that the TDD SP allocated to STA in one TDD Slot is not periodic, for example, as shown in fig. 6, TDD SP1 in TDD Slot k +1 is allocated to STA1, TDD SP3 in TDD Slot k +2 is allocated to STA1, and TDD SP1 in TDD Slot k +3 is allocated to STA 1. The STA1 cannot report the situation of the current TDD SP to the AP according to a feedback manner in the conventional scheme, and therefore, a feedback manner is urgently needed to enable the AP to know the occupation situation of the STA1 of the current TDD SP, so that the reasonability of time domain resource allocation is improved, and the communication efficiency is improved.
Fig. 7 shows a schematic flowchart of a method for reporting time domain resource information according to an embodiment of the present application. The embodiment of the application can be applied to a communication system for performing multi-level division on time domain resources. One way to divide the time domain resources in multiple stages may be: the time domain resource includes first stage periods including at least one second stage period, and each of the at least one second stage periods includes a plurality of third stage periods.
In a specific embodiment, the first-stage time interval is a service time interval SP, the second-stage time interval is a time division duplex time Slot TDD Slot, and the third-stage time interval is a time division duplex service time interval TDD SP; as shown in fig. 2, the time domain resource includes a service period SP, which may be divided into a plurality of TDD slots (slots), each of which may be further divided into a plurality of TDD SPs. In particular, the TDD Slot may be the same as Block in the legacy scheme.
The present application does not limit the division of time domain resources and the division names, and any division and division name substantially the same as the present application fall within the scope of the present application.
Specifically, the at least one TDD timeslot TDD Slot has the same structure, that is, the number of TDD service periods TDD SP included in a certain TDD timeslot TDD Slot is the same as the number of TDD service periods TDD SP included in other TDD timeslots TDD slots, and the duration of each TDD service period TDD SP included in a certain TDD timeslot TDD Slot is the same as the duration of the corresponding TDD service period TDD SP included in other TDD timeslots TDD slots.
It should be noted that the service period SP may be a unit in which the second device allocates a time domain resource to the service flow of the first device, for example, a Service Period (SP) in a communication system composed of an AP and an STA, or may be a unit in which a time domain resource is allocated to a service data flow in the other communication systems, which is not limited in this application. In addition, the names of the service period SP, the time division duplex time Slot TDD Slot, and the time division duplex service period TDD SP are not limited in the embodiments of the present application, and with the development of the communication system, other names having the same functions as those of the service period SP, the time division duplex time Slot TDD Slot, and the time division duplex service period TDD SP are within the scope of the present application. For convenience of description, the following embodiments take SP, TDD Slot, and TDD SP as examples.
701, the first device determines information of 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 from a plurality of TDD SPs in at least one TDD Slot, where 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 (NAV) and, in the case of setting a NAV, the duration of the set NAV; or whether the interference time of the TDD SP is greater than a preset threshold, or a specific interference time in the case of being greater than the preset threshold; whether the interference time proportion of one TDD Slot is larger than a preset threshold or not or the specific interference time proportion under the condition that the interference time proportion is larger than the preset threshold can be also adopted; or the TDD SP prefers a certain STA or STAs; it may also be whether the signal strength detected on the TDD SP is greater than a preset threshold, or the specific signal strength in case of being greater than a preset threshold; combinations of at least two of the foregoing, and the like.
It should be understood that the occupied state may indicate that the TDD SP has been assigned to certain devices or is performing signal processing.
It should be noted that the at least one TDD SP may be all TDD SPs included in the SP, may also be a part of TDD SPs included in the SP, and may also be one of the TDD SPs included in the SP, which is not limited in this application. Optionally, the first device determines information for each TDD SP of the at least TDD Slot; optionally, the first device determines information for each of the SPs; optionally, the first device determines information of at least one TDD SP allocated to the first device; optionally, the first device determines information of at least one unassigned TDD SP; optionally, the first device determines information of at least one unassigned TDD SP and at least one TDD SP allocated for the first device.
It should be noted that the triggering condition for the first device to determine the information of the TDD SP and send the first frame indicating the information of the TDD SP to the second device includes: the first device requires new TDD SP resources; or the first device needs to replace an existing TDD SP resource; or the first device receives a request element sent by a second device and used for requesting the first device to feed back TDD SP information, wherein the request element can be carried by a request frame or other frames; or the first device receives an indication element sent by a second device and used for indicating the first device to feed back the TDD SP information, where the indication element may be carried by an indication frame or other frames.
The first device needs new TDD SP resources, including: the current service flow rate is increased, the current service transmission rate is reduced, and a new service flow arrives.
The first device needs to replace an existing TDD SP resource, including: the first device detects interference on an existing TDD SP assigned to the first device, e.g., multiple times or periodically.
In particular, the request element or the indication element may have only one bit, where a1 in the bit indicates that the first device needs to measure the TDD SP, and a 0 in the bit indicates that the first device does not need to measure the TDD SP. For example, as shown in fig. 8, the Directional Channel Quality Request (Measurement Request field format for direct Channel Quality Request) for the Measurement Request field format includes a Measurement class (operating class), a Channel number (Channel number), an Application Identifier (AID) of a Measurement user, a reserved field, and a Measurement method (Measurement method), where the reserved field may be used as a field for requesting information to trigger the first device to send information for feeding back the TDD SP.
It should be noted that, if the at least one TDD timeslot includes a TDD SP currently serving the first device, the first device may not measure the current TDD SP, so as to avoid resource waste.
Optionally, the first device may receive the second frame sent by the second device and indicate the second frame for allocating to its TDD SP, so that the first device may measure only information of at least one TDD SP allocated to itself, and avoid detecting information that cannot be allocated to its TDD SP, thereby saving power consumption of the first device.
It should be understood that the request information described above may be carried in this second frame.
Optionally, the first device may further indicate an unallocated TDD SP after receiving the second frame sent by the second device, so that the first device may measure only an unallocated TDD SP, and avoid measuring an already allocated TDD SP, which may cause resource waste.
Optionally, the first device may receive the second frame sent by the second device and may also allocate a TDD SP to the first device in an unallocated TDD service period, so that the first device may measure only the TDD SP allocated to the first device in the unallocated TDD SP, thereby further saving power consumption of the first device.
Optionally, the second device may send the second frame to the second device when TDD SP needs to be added or replaced for the first device.
Optionally, the second device may also send the second frame to the second device when determining that the packet loss rate and/or the retransmission rate of the signal sent to the first device changes.
Optionally, the second device may also send the second frame to the second device when determining that the packet loss rate and/or the retransmission rate of the signal sent by the first device is changed.
Optionally, the second frame may include at least one field, and the at least one field and the at least one TDD SP have a one-to-one mapping relationship, so that a value of each field in the at least one field may be used to indicate the TDD SP that needs to be measured.
In particular, the at least one field may be a bitmap (bitmap) consisting of consecutive bits.
It should be noted that the field may include only the bitmap, or the field may further include bits with other functions, which is not limited in this application.
Optionally, the second frame may further include a field indicating a start position of the TDD SP that needs to be measured.
Specifically, the duration of the TDD SP may be a fixed value, that is, the second frame may include fixed-length fields, each field corresponding to one TDD SP to be measured, so that the first device may measure information of a fixed number of TDD SPs from the starting position of the TDD SP to be measured indicated by the second frame.
Optionally, the second frame may further include a field indicating a duration of the TDD SP. The duration of the TDD SP may be represented by the number of TDD slots or the number of TDD SPs. Thus, the first device can determine the TDD SP needing to be measured according to the field indicating the starting position of the TDD SP needing to be measured and the field indicating the time length of the TDD SP, thereby improving the flexibility of indicating the TDD SP needing to be measured.
The embodiments of the application can be applied to one TDD Slot, and can also be applied to a plurality of TDD slots.
In one embodiment, for the case of multiple TDD slots, the second frame may include an identification of the device requesting the measurement, an identification of the starting TDD Slot, and information indicating the number of TDD slots.
Specifically, the device identifier requesting measurement may be an identifier of an interfering device, and the interfering device may be an identifier of a channel occupant in the NAV record of the first device, for example, the device identifier is at least one bit, and the first device may determine, according to a value of the at least one bit, which device measures interference on some time domain resources of the first device by the first device. In addition, the second frame may also carry a Media Access Control (MAC) address of the interfering device.
For example, as shown in fig. 9, the starting TDD Slot is TDD Slot k +1, the number of TDD slots is 3, and the first device may measure information of all TDD SPs included in the three TDD slots, TDD Slot k +1 to TDD Slot k + 3.
Alternatively, since each TDD Slot includes the same number of TDD SPs, the number of TDD slots may also be represented by the number of TDD SPs. For example, as shown in fig. 10, one TDD Slot includes M TDD SPs, and the number of TDD SPs is 3 × M, which is the same as 3 TDD slots.
In another embodiment, the second frame may include an identification of the device requesting the measurement, an identification of the starting TDD Slot, and information indicating the number of TDD SPs.
For example, the starting TDD Slot is TDD Slot k +1 and TDD SP is 3, the first device may measure the information of three TDD SPs starting from the first TDD Slot in the TDD Slot k + 1.
In yet another embodiment, the second frame may further include only the starting time instant of the first TDD Slot of the SPs, and information indicating the number of TDD slots. As shown in fig. 11, the first device measures all TDD SPs from the start time instant of the first TDD Slot to the number of TDD slots from the start time instant of the first TDD Slot according to the second frame.
In yet another embodiment, the second frame may further include only an identification of the first one of the SPs, i.e. the first one of the first TDD slots, and information indicating the number of TDD slots, as shown in fig. 12.
In yet another embodiment, the second frame may further include only an identification of a first one of the SPs, and information indicating the number of TDD SPs.
Optionally, the second frame may further include a length indicating the bitmap.
In one embodiment, the second frame may include an identification of the device requesting the measurement, an identification of the starting TDD Slot, and a length of the bitmap of the TDD SP.
Specifically, the first device determines from the second frame information to measure TDD SPs starting from the first TDD Slot in TDD Slot k +1, where each bit in the TDD SP bitmap corresponds to one TDD SP, as shown in fig. 13.
It should be understood that the TDD SP corresponding to the bitmap of the TDD SP may be a TDD Slot in TDD Slot k +1, and may also include a TDD Slot in the next TDD Slot k +2, which is not limited in this application.
Optionally, the second frame may further include a target channel, and may further include the number of target channels (channel number).
Optionally, the second frame may further include a sector identification field or a beam identification field for indicating a target measurement direction.
It should be noted that the target ranging channel may be one or more sectors or beam directions.
Optionally, the second frame may further include a Band Width (BW).
Optionally, the second frame may include an element identification (element ID), a length (length), in addition to the various structures described above. For example, as shown in fig. 14.
Optionally, the second device may also carry a field indicating the defined condition in the request frame. The field may indicate at least one of a strength threshold of the feedback signal, an interference duration threshold, and a proportion threshold of the interference time to the TDD Slot.
Optionally, after detecting that the TDD SP is interfered by the device of the neighboring cell, the second device may also send the indication information to the central control node or the second device of the neighboring cell, so that the central control node or the second device of the neighboring cell does not occupy the TDD SP for signal transmission any more, thereby improving communication efficiency of the current cell.
In an embodiment, the second frame may be further used to indicate the number of TDD SPs included in the first TDD timeslot and the size of each TDD SP in the first TDD timeslot, so that the first device can know the TDD SPs specifically included in the first TDD timeslot. That is, the second frame may be used to indicate both the structure of the first TDD timeslot and the TDD SP allocated for the first device; or the second frame may be used to indicate both the slot structure of the first TDD and the unassigned TDD SP.
In another embodiment, the first device may further receive a third frame, where the third frame is used to indicate the number of TDD SPs included in the first TDD timeslot and the size of each TDD SP in the first TDD timeslot, and thus the first device can know the TDD SPs specifically included in the first TDD timeslot. That is, the second device independently transmits a third frame indicating a TDD slot structure and a second frame indicating a TDD SP allocated for the first device, respectively.
It is to be understood that the frame structure of the third frame may be as shown in fig. 4.
Optionally, the request information may also be carried in the third frame.
The first device transmits a first frame to the second device, the first frame indicating information of the at least one TDD SP. Accordingly, the second device receives the first frame transmitted by the first device.
In particular, the first frame may be information for indicating only the at least one TDD SP. Or the first frame may have other functions to indicate information of the at least one TDD SP through a reserved field.
Alternatively, the condition for measuring the TDD SP information may be a condition for transmitting the first frame. That is, the first device may periodically or continuously measure all the information of the TDD SP, and the first frame only carries the information of the TDD SP required by the second frame, i.e. the information of a part of the TDD SP.
Optionally, the first frame includes at least one first field, the at least one first field corresponds to the at least one TDD SP one-to-one, and each of the at least one first field is used to indicate information of the corresponding TDD SP.
In a specific embodiment, the first field may include at least one bit, for example, the first field is a bit, the value of the bit is "0" to indicate that the TDD SP is in the idle state, and the value of the bit is "1" to indicate that the TDD SP is in the occupied state; or, the value of the bit is "1" to indicate that the TDD SP is in an idle state, and the value of the bit is "0" to indicate that the TDD SP is in an occupied state. The method comprises the steps that a bitmap is formed by a plurality of 1-bit first fields, each bit of the bitmap corresponds to a TDD SP one by one, and information of the corresponding TDD SP is indicated through the value of each bit of the bitmap, for example, the TDD SP is in an idle state or an occupied state.
In another specific embodiment, the first field includes two bits, and a value of the two bits may indicate information of a corresponding TDD SP, for example, "00" may indicate that the TDD SP is in an idle state, "01" indicates that the TDD SP is used for device transmission, "10" indicates that the TDD SP is used for device reception, and "11" indicates reservation. The device receiving and the device sending may be for a receiving end device or for a sending end device, which is not limited in this application.
Optionally, the first frame further includes a second field, where the second field is used to indicate a starting location of a TDD SP that needs to be reported. The starting position of the TDD SP to be reported may be a starting time of a certain TDD Slot, for example, a starting time of a (k +1) th TDD Slot of option 1-3 in fig. 15, for example, a starting time of a1 st TDD Slot of option 4-5 in fig. 15; or the starting time of a certain TDD SP; this is not limited in this application.
Optionally, the first frame may further include a third field, where the third field is used to indicate a distribution length of the TDD SP that needs to be reported. The distribution length may be the number of TDD slots, for example, the 3 rd field in option1 in fig. 15; the number of TDD SPs may also be, for example, the 3 rd field in option2 in FIG. 15; the length of bitmap corresponding to TDD SP can also be, for example, the 3 rd field in option3 in fig. 15.
Optionally, the first frame may further include an SP identifier, which is used to identify an SP, such as an Allocation (Allocation) ID in fig. 15.
Alternatively, the first frame may correspond to the structure of the second frame described above. It should be understood that, in order to avoid repetition, the same portions of the first frame structure as the second frame structure are not described in detail herein.
Alternatively, the first frame may not correspond to the structure of the second frame, that is, the first frame may have any structure shown in fig. 15, regardless of the structure of the second frame shown in fig. 9 to 13.
Optionally, the structure of the first frame may further include fields such as an element ID, a duration, an element ID extension, a start time, a bitmap length, and a bitmap, as shown in fig. 16.
Optionally, the first device may further send feedback information carrying the preferred TDD SP to the second device, and the second device may allocate a reasonable TDD SP to the first device in combination with the feedback information.
And 703, the second device determines a target TDD SP according to the first frame, wherein the target TDD SP is used for signal transmission with the first device.
Alternatively, if the first frame is used to indicate that at least one TDD SP is in an idle state, the second device may select any one of the TDD SPs in the at least one idle state as the target TDD SP.
Optionally, the second device receives a fourth frame indicating a starting TDD SP position carrying the second signal before determining the target TDD SP in the at least one TDD Slot, so that the second device selects the TDD SP before the starting TDD SP position as the target TDD SP from the at least one TDD SP indicated by the first frame.
Optionally, the second device receives a fifth frame indicating a location of an ending TDD SP carrying the second signal before determining the target TDD SP in the at least one TDD Slot, such that the second device selects, as the target TDD SP, a TDD SP following the location of the ending TDD SP from the at least one TDD SP indicated by the first frame.
Optionally, the second device sends a signal to the first device on the target TDD SP.
Therefore, in the method for reporting time domain resource information according to the embodiment of the present application, the first device determines the information of at least one TDD SP in the first time slot that needs to be reported, and sends the first frame for indicating the information of the at least one TDD SP to the second device, so that the second device can configure a reasonable time domain resource for the first device according to the first frame, thereby improving communication efficiency.
In a conventional scheme, after receiving resource configuration information indicating a target TDD SP, sent by a second device, a first device performs signal transmission on the target TDD SP.
Fig. 17 is a schematic flowchart of a method for reporting time domain resource information according to another embodiment of the present application.
The same terms in the embodiments of the present application may have the same meanings as in the embodiments described above, and are not described herein again to avoid repetition.
1701, the second device sends resource configuration information to the first device, the resource configuration information indicating a target tertiary period in the at least one time division duplex time slot. Accordingly, the first device receives the resource configuration information.
Specifically, the target third-stage period may be one TDD SP or a plurality of TDD SPs.
1702, the first device listening for a signal at an interval prior to the target third stage period.
Specifically, if the target third-stage period is a plurality of TDD SPs, the first device may perform signal listening in a TDD SP interval before a foremost TDD SP in the plurality of TDD SPs, or may perform listening in a TDD SP interval before each TDD SP, which is not limited in this application. There may be one or more TDD SP intervals before the target TDD SP, and the first device may listen to all TDD SP intervals before the target TDD SP, may listen to any one of the TDD SP intervals, or may listen to the TDD SP interval closest to the target TDD SP.
Optionally, the resource configuration information may further indicate whether the first device needs to perform signal listening, and if the resource configuration information indicates that the first device needs to perform signal listening, the first device performs signal listening at a third-level time interval before the target third-level time interval.
Alternatively, if the resource configuration information indicates that the first device does not need to perform signal listening, the first device may perform signal transmission directly over the target third-stage time period.
Optionally, the first device may receive indication information indicating a TDD SP interval in the at least one TDD Slot.
Specifically, the indication information may indicate a start position and an end position of the TDD SP interval. The indication information may also indicate a start position or an end position of the TDD SP interval, and a TDD SP interval duration.
For example, as shown in fig. 18, the TDD SP interval includes an interval yIFS between uplink TDD SPs, yIFS between downlink TDD SPs, and an interval zffs between downlink TDD SPs and uplink TDD SPs.
Optionally, the first device may also determine whether to listen according to the size of the TDD SP interval. And if the TDD SP interval is greater than or equal to a preset duration threshold, the first equipment monitors in the TDD SP interval. If the TDD SP interval is smaller than the preset duration threshold, the first device may not listen in the TDD SP interval.
Alternatively, in the current communication system, the signal listening duration needs to be about one slot length (a slot time) + short frame spacing duration (SIFS time) ═ 8 μ s, so the preset duration threshold may be set to 8 μ s. For example, when the TDD SP interval is 3 μ s, the first device does not listen in the TDD SP interval.
Optionally, the preset duration threshold may also be a protocol agreed Time (apdgppminglisting Time), and specifically, the apdgppminglisting Time may be 150 μ s.
1703, the first device processes the signal according to the signal interception result.
Optionally, if the first device does not listen to signals between other devices, the first device sends a first signal to the second device on the target TDD SP.
Optionally, the transmission modes supported by the first device and the second device include a Multiple Input Multiple Output (MIMO) mode and a Single Input Single Output (SISO) mode, and in case of the MIMO mode, the first device is capable of communicating with the second device through Multiple beam directions. If the first device senses that a portion of the plurality of beam directions is idle during the TDD SP interval, the first device may transmit the first signal in the portion of the beam directions in a MIMO mode and on the target TDD SP. That is to say, the first device can further optimize the signal transmission mode according to the interception result, and improve the transmission efficiency.
Optionally, the transmission modes supported by the first device and the second device include a MIMO mode and a SISO mode, and the first device is capable of communicating with the second device through multiple beam directions in case of the MIMO mode. If the first device senses that only one of the plurality of beam directions is idle during the TDD SP interval, the first device may switch the MIMO mode to the SISO mode such that the first device may transmit the first signal on the target TDD SP in the idle beam direction using the SISO mode. That is to say, the first device can further optimize the signal transmission mode according to the interception result, and improve the transmission efficiency.
Optionally, if the first device senses the second signal and the second signal includes an end time at which the second signal completes transmission, the first device may send feedback information to the second device, where the feedback information is used to request the second device to reallocate the TDD SP after the end time or the feedback information is used to indicate the end time.
Specifically, the first device listens to the second signal and parses the second signal, which carries a NAV-protected directional transmission field, i.e., the first device can determine the transmission duration of the second signal from the second signal. Therefore, the first device reports the end time of the second signal to the second device, thereby avoiding the second device configuring the time domain resource with interference for the first device.
Or, the feedback information reported by the first device to the second device only indicates the end time, and the second device performs time domain resource configuration again according to the end time.
Therefore, according to the method for reporting time domain resource information in the embodiment of the present application, after receiving the resource configuration information indicating the target third-level time period for transmitting the first signal, the first device listens to the signal at an interval before the target third-level time period, and processes the signal according to a listening result, so that the first device can further avoid interference of other signals, and the reliability of signal transmission is improved.
In the conventional scheme, the first device analyzes the identifier of the next-hop device in the signal received by the MAC layer, and prepares an antenna configuration for the next-hop device.

Wherein, the header-B field, i.e. the aforementioned first sub-field, includes a device identifier of a next-hop device and a third sub-field, and the third sub-field is used to indicate a source identifier and a target identifier; the header-a includes a field indicating that the preamble field includes the first subfield.

Specifically, the first device stores a mapping relationship table, where the mapping relationship table includes a mapping relationship between the flow identifier and the source device identifier, and a mapping relationship between the flow identifier and the target device identifier. Thus, the first device can determine the flow identifier according to the third field, and determine the source device identifier and the target device identifier according to the flow identifier and the mapping relation table, thereby saving the length of the occupied field.

1903, the first device performs antenna configuration for the next-hop device at the physical layer.
Specifically, the first device receives a first frame at the physical layer, and can determine the device identifier of the next-hop device according to the first frame, so that the antenna configuration can be performed at the physical layer, thereby saving the antenna configuration delay.
Optionally, the first device may further receive a forwarding configuration table sent by the management entity, where the forwarding configuration table includes an address of the next-hop device. The first device may then communicate with the next hop device based on the address of the next hop device in the forwarding configuration table.
It should be understood that the forwarding configuration table may also include the address of the source device and the address of the destination device.
Therefore, in the method for reporting time domain resource information in the embodiment of the present application, the first device receives a first frame on the physical layer, where a preamble field of the first frame includes a first subfield used for indicating a device identifier of a next-hop device of the first device, and determines the device identifier of the next-hop device according to the first subfield, so that antenna configuration can be performed on the physical layer for the next-hop device, thereby saving antenna configuration delay.
In the conventional scheme, for a communication system in which a block in a time domain resource structure is further divided into a plurality of TDD SPs, the efficiency of the configuration mode for executing the MIMO mode in each TDD SP is relatively low.
Fig. 21 is a schematic diagram illustrating a method for reporting time domain resource information according to another embodiment of the present application.
The method for reporting the time domain resource information is applied to a communication system with time domain resources comprising a first-level time period, wherein the first-level time period comprises one or more second-level time periods, and at least one second-level time period comprises a plurality of third-level time periods.

Specifically, the antenna configuration information corresponding to different TDD SPs may be the same or different.
It should be noted that the first device in the embodiment of the present application may be the first device in each of the above embodiments, and may also be the second device in each of the above embodiments.
Optionally, the first device and the second device may agree in advance on a mapping relationship between different third-level periods and antenna configuration information.
Alternatively, the antenna configuration information may be a MIMO configuration number.

It should be understood that the target TDD SP may be one TDD SP or a plurality of TDD SPs.

The first device signals through the MIMO mode if the counter is greater than 0. That is, the first device may maintain a transmission mode in which the discontinuity can perform signal transmission using the MIMO mode as MIMO, thereby improving the efficiency of signal transmission.
Optionally, if the counter is 0, the first device switches from the MIMO mode to the SISO mode or the quasi-omni mode. That is, the first device may adjust a transmission mode for which signal transmission cannot be performed using the MIMO mode for a long time to a SISO mode or a quasi-omni mode to meet user requirements.
