Fig. 2A is an interactive schematic diagram illustrating a method of doing a time window according to an embodiment of the present disclosure. As shown in fig. 2A, an embodiment of the present disclosure relates to a method of doing a time window, the method comprising:

In step S2101, the network apparatus 102 transmits first signaling to the terminal 101.

In some embodiments, the terminal 101 receives the first signaling.

In some embodiments, the first signaling may carry subband resource indication information.

In some embodiments, the subband resource indicating information is used to indicate time domain resources and/or frequency domain resources occupied by the subband.

In some embodiments, the first signaling may be terminal-specific (UE-specific) signaling.

Illustratively, the first signaling may be downlink control information (Downlink Control Information, DCI), e.g., unicast DCI.

Wherein, the DCI format may be any one of the following:

DCI format0_0；DCI format0_1；DCI format0_2；DCI format0_3；

DCI format1_0；DCI format1_1；DCI format1_2；DCI format1_3。

wherein, DCI format0_x is used for scheduling a physical uplink control channel (Physical Uplink Shared Channel, PUSCH), and DCI format1_x is used for scheduling a physical downlink control channel (Physical Downlink Shared Channel, PDSCH).

The first signaling may be, for example, a medium access control unit (Medium Access Control Element, MAC CE).

In some embodiments, the first signaling may be group common signaling.

Illustratively, the first signaling may be DCI format 2-0, or other group common signaling.

In the embodiment of the present disclosure, the type of the first signaling is not limited.

In some embodiments, the content and format of the subband resource indicating information is not limited.

The subband resource indication information may be carried by a resource indication field of the unicast DCI, for example.

The subband resource indicating information may be carried by a MAC CE, for example.

The subband resource indication information may be carried by a group common DCI, for example.

In step S2102, the network device 102 transmits the second signaling to the terminal 101.

In some embodiments, the terminal 101 receives the second signaling.

In some embodiments, the second signaling is used to configure the first value.

In some embodiments, the first value is a number of time units included in the time window.

In some embodiments, the second signaling may be semi-static signaling. Including but not limited to radio resource control (Radio Resource Control, RRC) signaling or system messages.

The second signaling may be a system information block n (System Information Blockn, SIBn), where n is a positive integer.

In some embodiments, the time units included within the time window may be in units of slots (slots), orthogonal frequency division multiplexing symbols (Orthogonal Frequency Division Multiplexing symbol, OFDM symbols), duration (span), time division duplex (Time Division Duplexing, TDD) periods, radio frames, and so forth, which are not limited by the present disclosure. Wherein a span comprises one or more consecutive OFDM symbols within the same slot.

In step S2103, the terminal 101 determines a time window.

In some embodiments, the subband resource indicating information is validated within the time window.

In some embodiments, the time window is the effective time domain range of the subband resource indicating information.

In some embodiments, the terminal 101 may determine the time window based on a predefined manner. The predefined manner includes, but is not limited to, a protocol convention manner.

In some embodiments, the terminal 101 may determine the first point in time when the first signaling is received as a start point in time of the time window and the second point in time as an end point in time of the time window.

In one example, the second point in time is the point in time when the terminal 101 successfully received the next first signaling.

It will be appreciated that the terminal 101 may determine the time window from when the first signaling is received until the terminal 101 successfully receives the next adjacent first signaling.

In one example, before the terminal 101 successfully receives the second time of the next adjacent first signaling, the terminal 101 may always determine the resources occupied by the sub-band according to the sub-band resource indication information carried in the first signaling.

Illustratively, before the second time point, the terminal 101 may determine that the subband occupies the first resource indicated by the subband resource indicating information.

In some embodiments, terminal 101 may determine that the time window corresponds to a time division multiplexed, TDD, period.

In one example, a TDD period is a period of transmit and/or receive behavior. In an embodiment of the present disclosure, the terminal 101 may determine that the time window corresponds to a TDD period in which the first signaling is received.

In one example, if the terminal 101 does not receive the first signaling within the TDD period, it may be determined whether the sub-band is present within the TDD period based on a default rule.

For example, whether a subband is present in the TDD period may be determined based on whether a semi-static subband configuration is present in the TDD period.

Illustratively, if there is a semi-static subband configuration, i.e., network device 102 is configured with a semi-static subband configuration, terminal 101 may determine that there is a subband within the TDD period.

Further, the terminal 101 may determine that the resources occupied by the subband in the TDD period are second resources, which are determined based on a semi-static subband configuration.

For example, if there is no semi-static subband configuration, i.e., network device 102 is not configured with a semi-static subband configuration, terminal 101 may determine that there is no subband within the TDD period.

Further, the terminal 101 may determine resources within the TDD period according to the TDD configuration.

In some embodiments, the terminal 101 determines that the time window comprises a particular time window after the terminal 101 receives the first signaling.

In one example, the terminal 101 determines a first point in time at which the first signaling is received as a starting point in time of the time window, and determines a number of time units included in the time window as a first value.

In one example, the first value may be determined based on a predefined manner, such as based on a protocol convention.

For example, the terminal 101 may determine that the time window starts from a first time point, and the number of occupied time units is a first value agreed by the protocol, such as N TDD periods, or N time slots, or N radio frames, etc.

In one example, the terminal 101 receives second signaling to configure the first value.

For example, the terminal 101 may determine that the time window starts from a first point in time, and the number of occupied time units is a first value configured by the network device 102 through semi-static second signaling, such as N TDD periods, or N time slots, or N radio frames, etc.

In step S2104, the network apparatus 102 determines a time window.

In some embodiments, the network device 102 may determine the time window based on a predefined manner. The predefined manner includes, but is not limited to, a protocol convention manner.

In some embodiments, the network device 102 may determine a first point in time when the terminal 101 receives the first signaling as a starting point in time of the time window and a second point in time as an ending point in time of the time window.

It will be appreciated that the network device 102 may determine the time window from when the terminal 101 successfully receives the first signaling until when the terminal 101 successfully receives the next adjacent first signaling.

In one example, before the second time when the terminal 101 successfully receives the next first signaling, the network device 102 may determine that the terminal 101 always determines the resources occupied by the sub-band according to the sub-band resource indication information carried in the first signaling.

Illustratively, the network device 102 may determine that the subband occupies the first resource indicated by the subband resource indicating information before the second point in time.

In some embodiments, the network device 102 may determine that the time window corresponds to a time division multiplexed, TDD, period.

In one example, a TDD period is a period of transmit and/or receive behavior. In an embodiment of the present disclosure, the network device 102 may determine that the time window corresponds to a TDD period in which the first signaling is sent.

In one example, if network device 102 does not send the first signaling to terminal 101 within the TDD period, network device 102 may determine whether the sub-band is present within the TDD period based on a default rule.

Illustratively, the network device 102 may determine whether a subband is present in the TDD period based on whether a semi-static subband configuration is configured for the terminal 101 in the TDD period.

Illustratively, if the network device 102 is configured with a semi-static subband configuration, i.e., the network device 102 is configured with a semi-static subband configuration, the network device 102 may determine that there are subbands in the TDD period.

Further, the network device 102 may determine that the resources occupied by the sub-bands in the TDD period are second resources, the second resources being determined based on a semi-static sub-band configuration.

For example, if network device 102 is not configured with a semi-static subband configuration, network device 102 may determine that there are no subbands in the TDD period.

Further, the network device 102 determines that the terminal 101 determines resources in the TDD period according to the TDD configuration.

In some embodiments, the network device 102 determines that the time window comprises a particular time window after the terminal 101 receives the first signaling.

In one example, the network device 102 determines a first point in time when the terminal 101 successfully received the first signaling as a starting point in time of the time window, and determines a number of time units included in the time window as a first value.

For example, the network device 102 may determine that the time window starts at a first point in time, and the number of occupied time units is a first value agreed by the protocol, such as N TDD periods, or N time slots, or N radio frames, etc.

In one example, the network device 102 may configure the first value, e.g., send second signaling to the terminal 101, the second signaling being used to configure the first value.

For example, the network device 102 may determine that the time window starts from a first point in time, and the number of occupied time units is a first value configured by the network device 102 through semi-static second signaling, such as N TDD periods, or N time slots, or N radio frames, or the like.

In some embodiments, the network device 102 may perform uplink and downlink scheduling based on the TDD time slot configuration sent by the network device 102 before the subband resource indicating information is validated.

In the above embodiment, the network device may send the first signaling, where the first signaling carries the subband resource indication information, and further, the network device sends the time window indication information, so that the terminal determines the time window, and the subband resource indication information is valid in the time window, thereby improving reliability and availability of full duplex communication.

The above-described process is further illustrated below.

In the embodiment of the disclosure, when the full duplex terminal receives the dynamic signaling for indicating the subband time-frequency resource sent by the full duplex network device, the effective time domain range of the subband time-frequency resource indicated by the dynamic signaling is determined through the pre-definition of a protocol or the indication signaling of a base station.

Terminal side:

after receiving dynamic signaling for indicating the subband time-frequency resource information sent by the full duplex network equipment, the full duplex terminal determines the effective time domain range of the subband time-frequency resource information according to a predefined method of a protocol or explicit indication information of a base station.

In the method 1, the effective time domain range of the subband time-frequency resource is started after the terminal receives the dynamic indication information, and the next effective dynamic indication information is received by the terminal.

Before the terminal receives the dynamic signaling to update the time-frequency resource of the subband, the terminal always determines the time-frequency resource of the subband according to the successfully received dynamic subband time-frequency resource indication information.

In method 2, the effective time of the subband time-frequency resource is a TDD period (periodicity) in which the dynamic indication signaling is received, i.e. TDD UL-DL periodicity.

And if the terminal does not detect that the dynamic subband indication information is received in the TDD UL-DL periodicity, the terminal determines the subband configuration or the TDD configuration according to the semi-static signaling.

And if the base station configures semi-static subband configuration for the terminal, the terminal determines subband time-frequency domain resources according to the semi-static signaling.

And if the base station does not configure the semi-static subband configuration for the terminal, the terminal considers that the subband does not exist in the TDD UL-DL periodicity.

And 3, determining the effective time of the subband time-frequency domain resource through the indication information in the dynamic signaling.

The dynamic signaling for indicating the subband time-frequency domain resource comprises a time domain range in which the subband time-frequency resource takes effect.

And 4, the effective time of the subband time-frequency domain resource is a specific time window after the terminal receives the dynamic indication signaling.

Wherein the length of the time window is a predefined value of a protocol, such as N TDD UL-DL periodicity, or N slots, or N radio frames.

Alternatively, the length of the time window is a value configured by the base station through semi-static signaling, such as N TDD UL-DL periodicity, or N slots, or N radio frames.

Network equipment side:

after the duplex network equipment sends dynamic signaling for indicating the subband time-frequency resource information to the full duplex terminal, the effective time domain range of the subband time-frequency resource information of the terminal is indicated according to a method predefined by a protocol or explicit indication information of a base station.

The specific method, such as the terminal side, is not described herein.

And 2, the effective time of the subband time-frequency resource is TDD UL-DL periodic at which the dynamic indication signaling is received.

The specific method, such as the terminal side, is not described herein.

In embodiment 1, the terminal is a Rel-18 and subsequent terminals, which have half duplex capability or full duplex capability, and the patent is not limited in any way. It is assumed that the base station side performs full duplex operation on semi-static DL symbols of the TDD band or DL symbols indicated by SFI, that is, performs scheduling of downlink data and uplink data at the same time. It should be noted that, the base station side may also perform full duplex operation on the semi-static UL symbol of the TDD band or the UL symbol indicated by the SFI, that is, schedule downlink data and uplink data simultaneously. The semi-static flexible symbol is determined by a time division duplex uplink and downlink common configuration (tdd-UL-DL-configuration common) transmitted by the base station or by a time division duplex uplink and downlink dedicated configuration (tdd-UL-DL-configuration dedicated).

In this embodiment, it is assumed that a slot structure configured by the network device through TDD UL-DL configuration is a DDDFU, that is, in a TDD configuration period, the first 3 slots are DL slots, the 4 th slot is a flexible slot, and the 5 th slot is a UL slot. Of course, the embodiment method can be directly applied to other TDD UL DL slot structures.

Considering the requirements of the service load, interference condition, service type of the terminal and the like of the network equipment, the base station side dynamically adjusts the subband configuration in the SBFD slot through dynamic signaling. In this embodiment, the dynamic signaling for dynamically indicating the subband time-frequency resource is not limited.

In this embodiment, the full duplex network device and the full duplex terminal determine the time domain range in which the subband time-frequency resource indicated by the dynamic signaling takes effect by the following method:

and the effective time domain range of the subband time-frequency resource is started after the terminal receives the dynamic indication information, and the next effective dynamic indication information is received by the terminal.
