In one embodiment, the network device can configure a downlink subband for the terminal in an uplink time slot. If the network device can perform full-duplex communication and the terminal can perform half-duplex communication, the terminal can perform downlink communication in the downlink subband or perform uplink communication on frequency domain resources outside the downlink subband in the uplink time domain unit; if both the network device and the terminal can perform full-duplex communication, the terminal can perform downlink communication in the downlink subband or perform uplink communication on frequency domain resources outside the downlink subband in the uplink time domain unit.

In one embodiment, the network device can configure an uplink subband for the terminal in a downlink time slot. If the network device can perform full-duplex communication and the terminal can perform half-duplex communication, the terminal can perform uplink communication in the uplink subband or perform downlink communication on frequency domain resources outside the uplink subband in the downlink time domain unit; if both the network device and the terminal can perform full-duplex communication, the terminal can perform uplink communication in the uplink subband or perform downlink communication on frequency domain resources outside the uplink subband in the downlink time domain unit.

The network device can configure an uplink subband for the terminal in the downlink time slot, taking the example that the frequency domain resources corresponding to the downlink time slot include a bandwidth part (BandWidth Part, BWP).

In one embodiment, as shown in the time slot on the left side of FIG. 1 , in the downlink time slot, the frequency domain resources corresponding to the uplink subband do not overlap with the frequency domain resources of the downlink resources used for downlink reception;

In one embodiment, as shown in the middle time slot of FIG. 1 , in the downlink time slot, the frequency domain resources corresponding to the uplink subband completely overlap with the frequency domain resources of the downlink resources used for downlink reception;

In one embodiment, as shown in the right time slot of FIG. 1 , in a downlink time slot, the frequency domain resources corresponding to the uplink subband partially overlap with the frequency domain resources of the downlink resources used for downlink reception.

The following embodiments are described by taking as an example the case where, in a downlink time slot, the frequency domain resources corresponding to the uplink subband do not overlap with the frequency domain resources of the downlink resources used for downlink reception.

In one embodiment, when a network device configures an uplink subband for a terminal in a downlink time slot, the terminal configured with the uplink subband in the downlink time slot can perform uplink transmission in the uplink subband of the downlink time slot, and the terminal can be called a subband full-duplex (SBFD) terminal.

A terminal that is not configured with an uplink subband in a downlink time slot can only receive downlink transmission in the downlink time slot, and the terminal may be referred to as a legacy terminal.

In the downlink time slot, the network device can schedule the downlink transmission of the traditional terminal, where the downlink transmission includes but is not limited to the semi-static physical downlink shared channel (PDSCH), dynamic PDSCH, physical downlink control channel (PDCCH), channel state information reference signal (CSI-RS), positioning reference signal (PRS), etc. In the downlink time slot, the network device can also schedule the SFBD terminal to perform uplink transmission in the uplink subband.

Since in the downlink time slot, the network equipment will schedule the traditional terminal to receive downlink transmission and will also schedule the SBFD terminal to perform uplink transmission in the uplink subband. Therefore, in the downlink time slot, the downlink resources used for the traditional terminal to receive downlink transmission and the uplink resources used by the SBFD terminal to perform uplink transmission in the uplink subband may overlap.

As shown in case a in Figure 2, the network equipment configures an uplink subband for the SBFD terminal in the downlink time slot. The uplink subband corresponds to the entire downlink time slot in the time domain and corresponds to part of the downlink BWP in the frequency domain. In the downlink time slot, the downlink resources used for the traditional terminal to receive downlink transmission correspond to the entire downlink BWP in the frequency domain and to part of the time slot in the time domain; the uplink resources for the SBFD terminal to perform uplink transmission in the uplink subband correspond to part of the uplink subband in the frequency domain and to the entire time slot in the time domain. There is overlap between the downlink resources and the uplink resources.

As shown in case b in Figure 2, the network device configures an uplink subband for the SBFD terminal in the downlink time slot. The uplink subband corresponds to the entire downlink time slot in the time domain and corresponds to part of the downlink BWP in the frequency domain. In the downlink time slot, the downlink resources used for the traditional terminal to receive downlink transmission correspond to the entire downlink BWP in the frequency domain and to part of the time slot in the time domain; the uplink resources for the SBFD terminal to perform uplink transmission in the uplink subband correspond to part of the uplink subband in the frequency domain and to part of the time slot in the time domain. There is overlap between the downlink resources and the uplink resources.

As shown in case c in Figure 2, the network equipment configures an uplink subband for the SBFD terminal in the downlink time slot. The uplink subband corresponds to the entire downlink time slot in the time domain and corresponds to part of the downlink BWP in the frequency domain. In the downlink time slot, the downlink resources used for the traditional terminal to receive downlink transmission correspond to part of the downlink BWP in the frequency domain and part of the time slot in the time domain; the uplink resources for the SBFD terminal to perform uplink transmission in the uplink subband correspond to part of the uplink subband in the frequency domain and part of the time slot in the time domain. There is overlap between the downlink resources and the uplink resources.

As shown in case d in Figure 2, the network device configures an uplink subband for the SBFD terminal in the downlink time slot. The uplink subband corresponds to the entire downlink time slot in the time domain and corresponds to part of the downlink BWP in the frequency domain. In the downlink time slot, the downlink resources used for the traditional terminal to receive downlink transmission correspond to part of the downlink BWP in the frequency domain and part of the time slot in the time domain; the uplink resources for the SBFD terminal to perform uplink transmission in the uplink subband correspond to part of the uplink subband in the frequency domain and part of the time slot in the time domain. The downlink resources do not overlap with the uplink resources.

It should be noted that, case a, case b and case c in FIG. 2 are merely examples of several cases where uplink resources overlap with downlink resources, but the cases where uplink resources overlap with downlink resources are not limited to the above cases.

When in a downlink time slot, the downlink resources for the traditional terminal to receive downlink transmission overlap with the uplink resources for the SBFD terminal to perform uplink transmission in the uplink subband, on the one hand, the uplink transmission of the SBFD terminal in the uplink subband will be interfered with by the downlink transmission of the traditional terminal, such as cross-link interference (Cross-Link Interference, CLI); on the other hand, the downlink transmission of the traditional terminal will also be interfered with by the uplink transmission of the SBFD terminal in the uplink subband, such as inter-terminal CLI, and in some cases, such as when the network device does not send downlink information to the transmission terminal in the downlink time slot, the traditional terminal will also mistake the uplink signal sent by the SBFD terminal in the uplink subband as a useful signal for reception, resulting in the traditional terminal receiving performance being affected.

Figure 3 is a schematic flow chart of a resource processing method according to an embodiment of the present disclosure. The resource processing method shown in this embodiment can be executed by a network device, and the network device can communicate with a terminal, the network device includes but is not limited to a base station in a communication system such as a 4G base station, a 5G base station, and a 6G base station, and the terminal includes but is not limited to a mobile phone, a tablet computer, a wearable device, a sensor, an Internet of Things device, and other communication devices.

As shown in FIG3 , the resource processing method may include the following steps:

In step S101, it is determined that a downlink resource used by a first terminal for receiving downlink transmission overlaps with an uplink subband configured for a second terminal, and a rate matching resource (RMR) is configured for the second terminal in the uplink subband.

In one embodiment, the first terminal may be a traditional terminal, and the network device does not configure an uplink subband for the first terminal in a downlink time slot. The first terminal can only receive downlink transmissions in the downlink time slot and cannot perform uplink transmissions.

In one embodiment, the second terminal may be a SBFD terminal, and the network device configures an uplink subband for the second terminal in the downlink time slot. The second terminal may perform uplink transmission in the uplink subband of the downlink time slot, and may receive downlink transmission in frequency domain resources outside the uplink subband in the downlink time slot.

Since in the downlink time slot, the network device schedules the first terminal to receive downlink transmission and schedules the second terminal to perform uplink transmission in the uplink subband, in the downlink time slot, the downlink resources for the first terminal to receive downlink transmission may overlap with the uplink subband configured for the second terminal. This may cause the uplink transmission of the second terminal in the uplink subband to be interfered by the downlink transmission of the first terminal.

According to an embodiment of the present disclosure, when the network device determines that the downlink resources used by the first terminal for receiving downlink transmission overlap with the uplink subband configured for the second terminal, the network device can configure rate matching resources for the second terminal in the uplink subband, and then when the second terminal performs uplink transmission in the uplink subband, rate matching can be performed around the rate matching resources, wherein the rate matching around the rate matching resources includes sending uplink signals on resources other than the rate matching resources, and/or not sending uplink signals in the rate matching resources. Accordingly, it is possible to avoid the uplink resources used by the second terminal for uplink transmission in the uplink subband to overlap with the downlink resources used by the first terminal for receiving downlink transmission, thereby avoiding the uplink transmission of the second terminal in the uplink subband from being interfered with by the downlink transmission of the first terminal.

In one embodiment, the rate matching resource may cover the portion of the downlink resource used by the first terminal for receiving downlink transmission that overlaps with the uplink subband configured for the second terminal, that is, the portion of the downlink resource used by the first terminal for receiving downlink transmission that overlaps with the uplink subband configured for the second terminal may be located within the rate matching resource. Accordingly, the second terminal performs rate matching around the rate matching resource, and can completely avoid the uplink resource for uplink transmission in the uplink subband from overlapping with the downlink resource used by the first terminal for receiving downlink transmission.

In one embodiment, the network device may configure rate matching resources for the second terminal in the uplink subband upon determining that downlink resources used by the first terminal for receiving downlink transmission overlap with uplink resources used by the second terminal for uplink transmission in the uplink subband.

Because when the downlink resources used by the first terminal for receiving downlink transmission overlap with the uplink subband configured for the second terminal, the downlink resources used by the first terminal for receiving downlink transmission and the uplink resources used by the second terminal for uplink transmission in the uplink subband do not necessarily overlap, for example, in case d in Figure 2, the uplink transmission performed by the second terminal in the uplink subband is not interfered by the downlink transmission of the first terminal, then there is no need to configure rate matching resources for the second terminal in the uplink subband.

Therefore, the network device can configure rate matching resources for the second terminal in the uplink subband when determining that the downlink resources used by the first terminal for receiving downlink transmission overlap with the uplink resources used by the second terminal for uplink transmission in the uplink subband. Accordingly, the rate matching resources can be configured for the second terminal in the uplink subband only when the uplink transmission performed by the second terminal in the uplink subband is interfered by the downlink transmission of the first terminal. When the downlink resources used by the first terminal for receiving downlink transmission do not overlap with the uplink resources used by the second terminal for uplink transmission in the uplink subband, it is not necessary to configure rate matching resources for the second terminal in the uplink subband. This is conducive to simplifying the operation of the network device.

In one embodiment, the rate matching resource may cover the portion of the downlink resource for receiving downlink transmission by the first terminal that overlaps with the uplink resource for uplink transmission by the second terminal in the uplink subband, that is, the portion of the downlink resource for receiving downlink transmission by the first terminal that overlaps with the uplink resource for uplink transmission by the second terminal in the uplink subband may be located within the rate matching resource. Accordingly, the second terminal performs rate matching around the rate matching resource, thereby completely avoiding the overlap between the uplink resource for uplink transmission in the uplink subband and the downlink resource for receiving downlink transmission by the first terminal.

Figure 4 is a schematic flow chart of a resource processing method according to an embodiment of the present disclosure. The resource processing method shown in this embodiment can be executed by a network device, and the network device can communicate with a terminal, the network device includes but is not limited to a base station in a communication system such as a 4G base station, a 5G base station, and a 6G base station, and the terminal includes but is not limited to a mobile phone, a tablet computer, a wearable device, a sensor, an Internet of Things device, and other communication devices.

As shown in FIG4 , the resource processing method may include the following steps:

In step S401, it is determined that a downlink resource used by a first terminal for receiving downlink transmission overlaps with an uplink subband configured for a second terminal, and resources in the downlink resource that overlap with the uplink subband are punctured.

In one embodiment, the second terminal may be a SBFD terminal, and the network device configures an uplink subband for the second terminal in the downlink time slot. The second terminal may perform uplink transmission in the uplink subband of the downlink time slot, and may receive downlink transmission using frequency domain resources outside the uplink subband in the downlink time slot.

According to an embodiment of the present disclosure, when the network device determines that the downlink resources used by the first terminal for receiving downlink transmission overlap with the uplink subband configured for the second terminal, the network device can punch holes in the downlink resources that overlap with the uplink subband. Then, when the network device sends a downlink transmission to the first terminal, the resources in the downlink resources that overlap with the uplink subband will not be downlinked, thereby avoiding the uplink resources for uplink transmission by the second terminal in the uplink subband overlapping with the downlink resources for receiving downlink transmission by the first terminal, thereby avoiding the uplink transmission of the second terminal in the uplink subband being interfered with by the downlink transmission of the first terminal.

Figure 5 is a schematic flow chart of a resource processing method according to an embodiment of the present disclosure. The resource processing method shown in this embodiment can be executed by a network device, and the network device can communicate with a terminal, the network device includes but is not limited to a base station in a communication system such as a 4G base station, a 5G base station, and a 6G base station, and the terminal includes but is not limited to a mobile phone, a tablet computer, a wearable device, a sensor, an Internet of Things device, and other communication devices.

As shown in FIG5 , the resource processing method may include the following steps:

In step S501, it is determined that downlink resources used by a first terminal for receiving downlink transmission overlap with uplink resources used for uplink transmission in an uplink subband configured for a second terminal, and resources in the downlink resources that overlap with the uplink resources are punctured.

Since in the downlink time slot, the network device schedules the first terminal to receive downlink transmission and schedules the second terminal to perform uplink transmission in the uplink subband, in the downlink time slot, the downlink resources for the first terminal to receive downlink transmission and the uplink resources for the second terminal to perform uplink transmission in the uplink subband may overlap. This may cause the uplink transmission of the second terminal in the uplink subband to be interfered by the downlink transmission of the first terminal.

According to an embodiment of the present disclosure, when the network device determines that the downlink resources used by the first terminal for receiving downlink transmission overlap with the uplink resources configured to the second terminal for uplink transmission in an uplink sub-band, the network device can punch holes in the downlink resources that overlap with the uplink resources. Then, when the network device sends a downlink transmission to the first terminal, the resources in the downlink resources that overlap with the uplink resources will not be downlinked, thereby avoiding the uplink resources for uplink transmission by the second terminal in the uplink sub-band overlapping with the downlink resources for receiving downlink transmission by the first terminal, thereby avoiding the uplink transmission of the second terminal in the uplink sub-band being interfered with by the downlink transmission of the first terminal.

Figure 6 is a schematic flow chart of a resource processing method according to an embodiment of the present disclosure. The resource processing method shown in this embodiment can be executed by a network device, and the network device can communicate with a terminal, the network device includes but is not limited to a base station in a communication system such as a 4G base station, a 5G base station, and a 6G base station, and the terminal includes but is not limited to a mobile phone, a tablet computer, a wearable device, a sensor, an Internet of Things device, and other communication devices.

As shown in FIG6 , the resource processing method may include the following steps:

In step S601, downlink resources for receiving downlink transmission are configured for a first terminal in a downlink time slot, wherein the downlink resources do not overlap with an uplink subband configured for a second terminal in the downlink time slot.

According to an embodiment of the present disclosure, after the network device configures an uplink subband for the second terminal in a downlink time slot, when configuring a downlink resource for receiving downlink transmission for the first terminal in the downlink time slot, the downlink resource can be configured to not overlap with the uplink subband configured for the second terminal in the downlink time slot. Accordingly, it is possible to avoid the uplink resource for uplink transmission of the second terminal in the uplink subband overlapping with the downlink resource for receiving downlink transmission of the first terminal, thereby avoiding the uplink transmission of the second terminal in the uplink subband being interfered by the downlink transmission of the first terminal.

Figure 7 is a schematic flow chart of a resource processing method according to an embodiment of the present disclosure. The resource processing method shown in this embodiment can be executed by a network device, and the network device can communicate with a terminal, the network device includes but is not limited to a base station in a communication system such as a 4G base station, a 5G base station, and a 6G base station, and the terminal includes but is not limited to a mobile phone, a tablet computer, a wearable device, a sensor, an Internet of Things device, and other communication devices.

As shown in FIG. 7 , the resource processing method may include the following steps:

In step S701, downlink resources for receiving downlink transmission are configured for a first terminal in a downlink time slot, wherein the downlink resources do not overlap with uplink resources for uplink transmission in an uplink subband configured for a second terminal in the downlink time slot.

According to an embodiment of the present disclosure, after the network device configures an uplink subband for the second terminal in a downlink time slot, when configuring a downlink resource for receiving downlink transmission for the first terminal in the downlink time slot, the downlink resource can be configured to be non-overlapping with the uplink resource for uplink transmission in the uplink subband configured for the second terminal in the downlink time slot.
