Background technique

The version 18 (Release-18, Rel-18) full-duplex (duplex) enhancement project will study the full-duplex solution. Specifically, the network side can receive data simultaneously within a time slot (slot). and send. As a possible solution, the network side schedules or instructs full-duplex terminals to send or receive data on semi-static flexible symbols. However, for semi-static flexible symbols, the network side can use the slot format indicator (Slot Format Indication, SFI) to indicate that the transmission direction is downlink (DownLink, DL), uplink (UpLink, UL) or dynamically variable (dynamic). flexible).

When the transmission direction indicated by SFI conflicts with the subband transmission direction scheduled by the base station on the semi-static flexible symbol, how the terminal handles it depends on whether the base station side needs to perform full-duplex operation on the symbol and whether the terminal supports full-duplex manual operation. In other words, terminals have different terminal behavior on the semi-static flexible symbol.

There is no corresponding solution on how to ensure that the base station side and the terminal side have the same understanding of terminal behavior.

In step 803', based on the terminal type, determine the terminal behavior of the terminal on a designated time unit; wherein the designated time unit is a time unit with variable transmission direction preconfigured by the base station.

In the above embodiment, the terminal may report second indication information to the base station. The base station determines whether the terminal type is a full-duplex terminal based on the second indication information. The base station determines the terminal behavior of the terminal in a designated time unit based on at least the terminal type. This achieves the purpose of ensuring that the base station and the terminal have a consistent understanding of the terminal behavior in a specified time unit, and improves the feasibility of full-duplex communication.

In some optional embodiments, in response to the base station determining that the first indication information or the second indication information reported by the terminal is not received, the base station may determine that the terminal type of the terminal is a non-full-duplex terminal, and then the base station determines that the terminal The first transmission direction of the subband supporting transmission on the designated time unit is the same as the second transmission direction of the designated time unit indicated by the slot format indicator SFI. That is, it is determined that the terminal does not expect that the first transmission direction of the subband scheduled by the base station on the designated time unit is different from the second transmission direction of the same designated time unit indicated by the SFI.

In some optional embodiments, the subband transmitted in the specified time unit can be UL subband or DL subband. The subband can be configured by the base station through explicit signaling, or obtained by the terminal in an implicit manner. This disclosure is useful for This is without any limitation. The above method is further illustrated below with examples.

Embodiment 1 assumes that the terminal is a Rel-18 or later version terminal with half-duplex capability or full-duplex capability. This patent does not make any limitations. It is assumed that the base station side performs full-duplex operation on the semi-static flexible symbol in the TDD frequency band, that is, it schedules downlink data and uplink data at the same time. The semi-static flexible symbol can be determined by the following information sent by the base station:

tdd-UL-DL-ConfigurationCommon;

tdd-UL-DL-ConfigurationCommon, tdd-UL-DL-ConfigurationDedicated.

The base station indicates the terminal's transmission direction on the semi-static flexible symbols in the following two ways. This embodiment does not impose any restrictions:

The base station configures UL subband or DL subband for the terminal. Within the UL subband, the terminal can only perform uplink transmission; within the DL subband, the terminal can only perform uplink reception. The base station performs data channel scheduling or reference signal indication within the UL subband or DL subband.

The base station instructs the terminal to send or receive on the semi-static symbol through scheduling information or high-level configuration. The base station does not need to explicitly configure UL subband or DL subband for the terminal.

Further, the base station indicates the transmission direction of the semi-static flexible symbol through SFI, that is, according to the service status or interference status, the base station indicates the semi-static flexible symbol as DL, UL or dynamic flexible.

In this embodiment, it is assumed that the time slot structure configured by the base station through TDD UL-DL configuration is DFFFF, that is, during the TDD configuration period, the first slot is DL slot, and the remaining 4 slots are flexible slots. Refer to Figure 9A shown. Of course, this embodiment method can also be directly applied to other TDD UL DL time slot structures.

In this embodiment of the present disclosure, it is assumed that the base station schedules uplink transmission on the UL subband on the semi-flexible symbol, that is, the uplink subband is configured on the last four slots shown in Figure 9A. Refer to Figure 9B . It should be noted that the uplink transmission may be uplink data or uplink reference signals, and this patent does not impose any restrictions.

In this embodiment, it is assumed that the duplex terminal supports data transmission or data reception on the semi-static flexible symbol, and supports that the first transmission direction of the subband is different from the second transmission direction of the semi-static flexible symbol indicated by the SFI. . The duplex terminal may report the first indication information or the second indication information to the base station, thereby reporting its terminal type or whether the terminal capability of the specific full-duplex communication capability is reported to the base station. Based on the first indication information or the second indication information reported by the terminal, the base station determines whether the terminal supports the first transmission direction of the subband that is different from the second transmission direction of the semi-static flexible symbol indicated by the SFI.

Referring to Figure 10, in response to the terminal type being a full-duplex terminal, it is determined that the terminal supports data transmission or data reception on the last 4 slots, and it is determined that the terminal supports the subband transmitted on the last 4 slots. The first transmission direction (upstream) is different from the second transmission direction of the last 4 slots indicated by the SFI.

Assume that the second data transmission direction indicated by the SFI sent by the base station is: DDDSU. Among them, D represents downward, S represents variable, and U represents upward. That is, the terminal supports that the first transmission direction (uplink) in the second, third, and fourth slots is different from the second transmission direction (DDS) indicated by the SFI.

Further, in response to the base station not receiving the first indication information or the second indication information reported by the terminal, the base station may determine that the terminal type of the terminal is a non-full-duplex terminal, and the base station will not indicate through the SFI the first indication information of its subband. Slot structure with opposite transmission direction. Referring to Figure 10, in response to the base station configuring the uplink subbands in the last four slots, the time slot structure of the last four slots indicated by the SFI sent by the base station should be: UUUU.

It should be noted that the DL symbol or flexible symbol indicated by the SFI partially or completely overlaps with the terminal's uplink transmission in the UL subband, and this disclosure does not limit this.

Embodiment 2 assumes that the terminal is a Rel-18 or subsequent version terminal with half-duplex capability or full-duplex capability. This patent does not make any limitations. It is assumed that the base station side performs full-duplex operation on the semi-static flexible symbol in the TDD frequency band, that is, it schedules downlink data and uplink data at the same time. The semi-static flexible symbol can be determined by the following information sent by the base station:

tdd-UL-DL-ConfigurationCommon;

tdd-UL-DL-ConfigurationCommon, tdd-UL-DL-ConfigurationDedicated.

In this embodiment, the base station determines that the terminal type is a full-duplex terminal through the first indication information or the second indication information reported by the terminal. The base station can indicate to the terminal through RRC signaling whether the base station performs full-duplex on the semi-static flexible symbol. Duplex operation. Further, the base station and the terminal determine the terminal behavior of the full-duplex terminal through the RRC signaling:

In response to the base station performing a full-duplex operation on the semi-static flexible symbol, the full-duplex terminal supports data transmission or data reception on the flexible symbol, and determines that the terminal supports the first transmission direction of the subband and is consistent with the SFI. The indicated second transmission direction is different. The specific implementation is similar to that in Figure 10 and will not be described again here.

In response to the base station not performing full-duplex operation on the semi-static flexible symbol, the terminal can adopt the existing mechanism, that is, the first transmission direction of the subband scheduled by the base station is the same as the second transmission direction indicated by the SFI. Correspondingly, the base station will not indicate the time slot structure opposite to its scheduling direction through SFI.

In the above embodiment, the base station and the terminal can determine the terminal behavior based on predefined rules in a designated time unit with variable transmission direction, ensuring that the base station and the terminal have a consistent understanding of the terminal behavior in the designated time unit, improving full-duplex communication feasibility.
