[0042] To better understand the technical solutions of the embodiments of the present application, the following contents are first introduced:

[0043] NR Uu beam alignment

[0044] Taking downlink beam alignment as an example, beam alignment can be roughly divided into two phases. The first phase involves preliminary training of the initial transmission beam from the base station to the UE when the UE accesses the network. The second phase involves fine-tuning the transmit and receive beam alignment from the base station to the UE after the UE establishes a connection. This second phase of beam training is primarily accomplished through channel state information (CSI) measurement and feedback.

[0045] For the first phase, the base station periodically sends a synchronization signal block (SSB) and sends a group of SSBs in a beam scanning manner in each SSB transmission period. The UE measures the reference signal carried by the SSB and reports the index of the SSB with higher reception energy so that the base station can determine its transmission beam. The UE reports the SSB index according to the rules specified in the protocol. Each SSB corresponds to a group of PRACH resources. The UE sends the preamble for initial access on the corresponding PRACH resource, which represents the UE reporting the corresponding SSB index. For the second phase, see the R15 NR Uu CSI acquisition process for details. Figure 1a The base station configures the CSI reporting parameters and triggers CSI reporting. The UE measures and reports CSI according to the base station configuration information. The base station adjusts transmission parameters such as uplink and downlink beams according to the UE reporting results. Each CSI reporting configuration indicates the type of CSI reporting (CSI quantity), including parameters indicating the beam such as CRI (CSI-RS resource indicator) and SSB index, as well as other parameter types such as precoding matrix indication (PMI), rank indication (RI), channel quality indicator (CQI), layer indication (LI), reference signal received power (RSRP), signal-to-noise and interference ratio (SINR), codebook index, etc.

[0046] For uplink beam training, the base station configures a sounding reference signal (SRS) resource for uplink beam training for the UE, and the UE autonomously sends the SRS on the corresponding SRS resource for beam training.

[0047] In addition, for beam training on the base station / UE side, the base station / UE can independently select the training beam.

[0048] NR Uu beam indication

[0049] For uplink beam indication, the base station indicates the beam direction used by the UE on the UL scheduled resources. The beam direction is represented by the SRI (SRS resource indicator). For downlink beam indication, the base station indicates the beam direction on the DL scheduled resources so that the UE can determine its receive beam. The downlink beam direction is indicated by the associated Transmission Configuration Indication (TCI), where the TCI reflects information such as the CRI and SSB index.

[0050] Slot format

[0051] like Figure 1b As shown in FIG, in order to achieve flexible network deployment, the NR system configures the transmission direction of each symbol in a time slot by means of a time slot format.

[0052] In NR, there are three definitions of transmission direction for time slots: downlink (DL), uplink (UL), and flexible. When the network configures a time slot or symbol as DL or UL, the transmission direction at that moment is clear; when the network configures a time slot or symbol as flexible, the transmission direction at that moment is undetermined. The network can modify the transmission direction of a flexible time slot or symbol through dynamic signaling, such as the dynamic SFI (slot format indicator).

[0053] A slot can contain downlink, uplink, and flexible OFDM symbols; Flexible symbols can be rewritten as downlink or uplink symbols.

[0054] The slot format indicator (SFI) can indicate the format of one or more slots. The SFI is sent in the GC-PDCCH.

[0055] (1) SFI can flexibly change the slot format according to demand to meet business transmission requirements;

[0056] (2) The UE decides whether to monitor the PDCCH according to the SFI instruction.

[0057] slot configuration

[0058] (1) The base station can semi-statically configure one or more cell-specific slot formats for the UE through the higher-layer parameters UL-DL-configuration-common and UL-DL-configuration-common-Set2 (optional);

[0059] (2) The base station can also semi-statically configure one or more UE-specific slot formats for the UE through the higher-layer parameter UL-DL-configuration-dedicated;

[0060] (3) The base station can rewrite the flexible symbol or slot in the semi-static configuration through the SFI carried in the GC-PDCCH.

[0061] The transmission directions implicitly indicated by the UE-specific RRC configuration are collectively referred to as measurements, including

[0062] (1) Periodic or semi-persistent CSI-RS measurement, periodic CSI reporting, and uplink and downlink transmission directions implicitly indicated by periodic or semi-persistent SRS configured by UE-specific RRC signaling;

[0063] (2) UE-specific RRC-configured PRACH resources, type 1 and type 2 grant-free uplink transmission;

[0064] (3) For type 2 ungranted uplink transmission, only the transmission on the first activated resource is considered as UE-specific data.

[0065] UE-specific transmissions include PDCSH, PUSCH, PDSCH A / N feedback, DCI-triggered aperiodic measurements, etc.

[0066] The characteristics of R18 flexible / full duplex operation on the network side and half-duplex operation on the user / terminal side are symmetrical spectrum for FDD:

[0067] The uplink or downlink spectrum of FDD can be semi-statically configured or dynamically indicated as downlink or uplink transmission in certain time slots / symbols, such as Figure 1c shown.

[0068] For asymmetric spectrum of TDD:

[0069] Different frequency domain resources on certain TDD time slots / symbols can be semi-statically configured or dynamically indicated as having both uplink transmission and downlink reception, such as Figure 1dshown.

[0070] For half-duplex terminals, only uplink transmission or downlink reception can be performed at the same time, that is, the terminal cannot receive and send signals at the same time. Figure 1e and Figure 1f As shown, they correspond to the network side Figure 1c and Figure 1d

[0071] Existing mechanisms typically require the exchange of information, such as TDD configuration information, between base stations to prevent cross-link interference. However, this information is typically static and does not reflect the transmission status of different frequency bands. It only reflects the transmission status of the base station's overall spectrum, not the transmission status of specific frequency bands. Therefore, it cannot effectively reduce the impact of interference between full-duplex base stations.

[0072] The transmission scheduling method provided in the embodiments of the present application is described in detail below through some embodiments and their application scenarios in combination with the accompanying drawings.

[0073] See also Figure 2 The figure shows two network devices (gNB1 and gNB2), as well as UE1 and UE2 connected to gNB1, and UE3 and UE4 connected to gNB2. In the spectrum diagram of the two, D represents downlink transmission, U represents uplink transmission, and S represents that the transmission state is flexibly set. As shown in the spectrum diagram, on the time domain resource of T1, gNB1 has three subbands (Subband1 to 3) that are DSU, and on the time domain resource of T1, gNB2 has three subbands (Subband1 to 3) that are USD. At the same time, UE1 performs uplink transmission on Subband3 of gNB1, UE2 performs downlink transmission on Subband1 of gNB1, UE3 performs uplink transmission on Subband1 of gNB2, and UE4 performs downlink transmission on Subband3 of gNB2. At this time, due to cross-link interference between gNB1 and gNB2 on Subband1 and Subband3, interference occurs between UE1 and UE4, and interference occurs between UE2 and UE3.

[0074] See also Figure 3 , an embodiment of the present application provides a transmission scheduling method, including:

[0075] Step 301: The first network device sends scheduling auxiliary information to the second network device;

[0076] The scheduling auxiliary information includes one or more of the following:

[0077] (1) The transmission format of one or more frequency domain subbands of the first network device on one or more time domain resources; that is, the scheduling assistance information is indicated from the perspective of the time domain, for example, according to Figure 2 In the frequency plot shown in , indicates one or more columns in the spectrogram.

[0078] (2) The transmission format of one or more time domain resources on one or more frequency domain subbands of the first network device, such as TDD configuration information or time slot format; that is, the scheduling auxiliary information is indicated from the frequency domain perspective, for example, according to Figure 2 In the frequency plot shown in , the indicator is one or more lines in the spectrogram.

[0079] It should be noted that the "time domain resources," "frequency domain subbands," "frequency domain resources," and the like mentioned in the embodiments of the present application may specifically refer to flexible duplex resources or full duplex resources. For example, certain time domain resources or certain frequency domain bandwidths may be used as flexible duplex resources or full duplex resources, and the scheduling assistance information indicated by the network device corresponds to these flexible duplex resources or full duplex resources.

[0080] Flexible duplex resources or full duplex resources can be TDD or FDD spectrum resources. Specifically, they can be DL, UL or Flexible resources.

[0081] In addition to flexible duplex resources or full duplex resources, other resources are not limited, such as half-duplex resources, existing FDD or TDD spectrum, etc.

[0082] It can be understood that if the above methods (1) and (2) are used to indicate the entire frequency range, for example, if method (1) is used to indicate all columns of the spectrum diagram, or method (2) is used to indicate all rows of the spectrum diagram, then the contents indicated by the above methods (1) and (2) can be the same.

[0083] (3) Frequency domain resource allocation information scheduled by the first network device.

[0084] In an embodiment of the present application, the above-mentioned scheduling auxiliary information can reflect the transmission status of the network device itself on different frequency bands. The network device can obtain the transmission status of other network devices on different frequency bands through interactive scheduling auxiliary information. In this way, the network device can adjust its own transmission based on the known transmission status of other network devices, thereby avoiding cross-link interference with other network devices and ensuring transmission performance.

[0085] Specifically, the first network device may refer to Figure 2 In the scenario shown, gNB1 or gNB2, correspondingly, the second network device refers to Figure 2 Regarding gNB2 or gNB1 in the scenario shown, it should be noted that, in actual implementation, gNB2 and gNB1 need to send scheduling assistance information to each other. That is, the above-mentioned first network device sending scheduling assistance information to the second network device actually includes gNB1 sending scheduling assistance information to gNB2 that can reflect the transmission status of gNB1 on different frequency bands. Correspondingly, gNB2 also sends scheduling assistance information to gNB1 that can reflect the transmission status of gNB2 on different frequency bands. In this way, gNB1 and gNB2 can understand each other's transmission status on different frequency bands, and then adjust their own transmission according to each other's transmission status, thereby avoiding cross-link interference between each other.

[0086] It should be noted that after the above-mentioned network devices learn the transmission status of each other on different frequency bands, the adjustment operations performed to avoid cross-link interference can adopt existing transmission adjustment methods, and the embodiments of the present application do not specifically limit this.

[0087] In one possible implementation, the frequency domain resource allocation information is resource allocation information on one or more frequency domain subbands, and / or the frequency domain resource allocation information is resource allocation information on frequency domain subbands corresponding to one or more time domain resources; that is, the frequency domain resource allocation information may be resource allocation from a frequency domain perspective, or the frequency domain resource allocation information may be resource allocation from a time domain perspective, or a combination of the two.

[0088] In a possible implementation, the frequency domain resource allocation information is indicated by indicating all frequency domain sub-bands via a bitmap, for example, a frequency domain sub-band with transmission is “1”, and a frequency domain sub-band without transmission is “0”.

[0089] In a possible implementation manner, the indication content of the frequency domain resource allocation information includes one or more of the following:

[0095] (3) DMRS configuration parameters on one or more frequency domain subbands, based on which interference coordination can be performed to avoid using the same or more interfering DMRS resources or DMRS ports;

[0096] (4) Bandwidth part (BWP) configuration information, based on which interference coordination in the frequency domain is performed to understand the configuration information related to DL reception and UL transmission on the BWP;

[0097] (5) Interference and load indication information on one or more frequency domain subbands. Specifically, the interference and load indication information on each frequency domain subband may be reported, for example, including: high interference indication (High Interference Indication), overload indication (Overload Indication), etc. The interference and load indication information is used to indicate the subbands on the frequency domain resources that will cause strong interference or have strong interference.

[0098] In a possible implementation manner, the configuration information of the reference signal on one or more frequency domain subbands includes one or more of the following:

[0099] (1.1) Resource mapping information;

[0127] In the embodiment of the present application, the sending of the scheduling assistance information is triggered by a timer. The network can configure different timers for reporting different types of scheduling assistance information, and the durations of different timers can be different.

[0128] Specifically, one implementation involves: when the conditions for triggering the transmission of scheduling auxiliary information are met, a timer is started. During the timer's duration, the auxiliary information is not transmitted. After the timer expires, the auxiliary information is transmitted. At this point, a new timer can be started. Another implementation involves: when the conditions for triggering the transmission of scheduling auxiliary information are met, a timer is started. During the timer's duration, the auxiliary information is transmitted. After the timer expires, the auxiliary information is not transmitted.
