[0001] CROSS-REFERENCE TO RELATED APPLICATIONS

[0002] This application is based on the Chinese patent application with application number 202211557429.1 and application date of December 6, 2022, and claims the priority of the Chinese patent application. The entire content of the Chinese patent application is hereby introduced into this application in its entirety. Technical Field

[0003] The present application belongs to the field of wireless communication technology, and specifically relates to a resource configuration method, apparatus, communication equipment, and readable storage medium. Background Art

[0004] In subband full-duplex technology, different subbands within a carrier can be configured for different transmission directions, enabling both downlink and uplink transmission opportunities at the same time, thereby reducing latency in time division duplex (TDD) systems. For example, a carrier can be divided into three subbands: two downlink subbands on either side of the carrier and one uplink subband in the center. One approach to allocating uplink subband resources is to define it as an uplink bandwidth part (BWP), whose bandwidth is smaller than the carrier bandwidth. However, in the last full uplink timeslot of a TDD frame structure, the terminal needs to switch to an uplink BWP with a larger bandwidth, and BWP switching can cause communication interruption. Furthermore, currently, downlink reference signals or continuously mapped physical downlink shared channels (PDSCHs) only support continuous resource mapping. Therefore, the base station can only allocate reference signal resources for a terminal in two downlink subbands or schedule continuous PDSCH resources within a single downlink subband. However, the maximum number of reference signal resources that a terminal can support is limited. In this case, how to efficiently configure uplink / downlink resources in a sub-band full-duplex system is an urgent problem that needs to be solved.

The access network device may also be referred to as a radio access network device, a radio access network (RAN), a radio access network function, or a radio access network unit. The access network device may include a base station, a WLAN access point, or a WiFi node.

[0034] The resource configuration method, apparatus, communication device, and readable storage medium provided in the embodiments of the present application are described in detail below with reference to the accompanying drawings through specific embodiments and their application scenarios.

[0035] Please refer to FIG2 , which is a flowchart of a resource configuration method provided in an embodiment of the present application. The method is executed by a network-side device. As shown in FIG2 , the method includes the following steps:

[0036] Step 21: The network side device sends first configuration information to the terminal; the first configuration information is used to configure a first frequency domain resource for the terminal, the first frequency domain resource is used for the uplink transmission of the terminal, and / or, the first frequency domain resource is not used for resource mapping of the downlink reference signal and / or downlink channel.

[0037] Here, the first frequency domain resource may be used for the uplink transmission of the terminal, or may not be used for resource mapping of the downlink reference signal and / or downlink channel, or may be used for both uplink transmission of the terminal and resource mapping of the downlink reference signal and / or downlink channel. That is, the first frequency domain resource may indicate the frequency domain resource position of the terminal uplink transmission, or may be used to indicate the position of the downlink reference channel / downlink signal of the terminal that is not used for resource mapping, or may indicate the frequency domain resource position of the terminal uplink transmission and may be used to indicate the position of the downlink reference channel / downlink signal of the terminal that is not used for resource mapping. The first frequency domain resource may be located within the uplink BWP and / or downlink BWP of the terminal.

[0038] Optionally, the first configuration information includes: a starting resource block (RB) and bandwidth of the first frequency domain resource. For example, the starting RB is a reference common resource block (CRB), such as CRB 0.

[0039] Optionally, the downlink reference signal includes but is not limited to a channel state information reference signal (Channel State Information Reference Signal, CSI-RS) and the like.

[0040] In this way, the first frequency domain resource configured in the embodiment of the present application for uplink transmission of the terminal can be configured in the uplink BWP of the terminal, so that when the terminal switches from the uplink sub-band of the first frequency domain resource to the uplink BWP, there is no need to perform RF switching and BWP switching, but only adjust the configuration parameters, which can avoid communication interruption; and the first frequency domain resource configured in the embodiment of the present application that is not used for resource mapping of downlink reference signals and / or downlink channels can be configured in the downlink BWP of the terminal, so that the terminal can always work in one downlink BWP, realizing downlink reference signal / downlink channel mapping on multiple non-continuous downlink sub-bands, and the base station does not need to configure multiple sets of downlink reference signals / downlink channels for the terminal on multiple downlink sub-bands, thereby efficiently performing resource configuration.

[0041] Optionally, the resource configuration method in this embodiment further includes:

[0042] A network-side device sends first information to a terminal; wherein the first information is used to configure or indicate time unit information of the terminal, and the time unit information includes at least one of the following: a first time unit, a second time unit, or a third time unit; the first time unit is a time unit configured with the first frequency domain resource, the second time unit is an uplink time unit, and the third time unit is a downlink time unit. This enables efficient uplink and downlink transmission in combination with the configured first frequency domain resource.

[0043] Furthermore, when the first frequency domain resource is used for the uplink transmission of the terminal, in the first time unit, the uplink transmission of the terminal is within the first frequency domain resource, that is, the terminal performs uplink transmission within the first frequency domain resource; in the second time unit, the uplink transmission of the terminal is within the uplink bandwidth part BWP, that is, the terminal performs uplink transmission within the uplink BWP.

[0044] Optionally, the first frequency domain resource is located within the uplink BWP of the terminal. For example, when the first frequency domain resource is used for uplink transmission of the terminal, the first frequency domain resource is located within the uplink BWP of the terminal. In this way, the terminal can always operate within the uplink BWP, so that the terminal can switch between the first time unit and the second time unit without any interruption.

[0045] In some embodiments, the first information may be configuration information or indication information, such as downlink control information DCI.

[0046] Here, the above-mentioned time unit may be a time slot or a symbol, etc.

[0047] For example, taking time slots as an example, the base station can indicate time slot information through signaling, and the time slot information includes a first time slot and a second time slot; wherein, the first time slot is a time slot configured with a first frequency domain resource. In the first time slot, if it is a terminal performing uplink transmission, its uplink transmission is within the first frequency domain resource, that is, the terminal performs uplink transmission within the first frequency domain resource; the second time slot is an uplink time slot. In the second time slot, the uplink transmission of the terminal is within the uplink BWP where the first frequency domain resource is located, that is, the terminal performs uplink transmission within this uplink BWP. For example, the type of the first time slot corresponds to a full-duplex time slot, in which the base station can perform uplink and downlink at the same time, but the terminal is half-duplex; the type of the second time slot corresponds to a half-duplex time slot, in which the base station can only perform uplink or downlink.

[0048] Optionally, the resource configuration method in this embodiment further includes:

[0049] The network device sends two sets of configuration information to the terminal; the two sets of configuration information include a first set of configuration information for uplink channels and / or uplink signals, and a second set of configuration information for the uplink BWP. The first set of configuration information is used for the first frequency domain resource, and the second set of configuration information is used for the uplink BWP. In this way, the terminal can switch from operating in the uplink subband of the first frequency domain resource to operating in the uplink BWP by simply adjusting the configuration parameters.

[0050] Furthermore, in the first time unit, that is, when the terminal's uplink transmission is within the first frequency domain resource, the first set of configuration information takes effect; in the second time unit, that is, when the terminal's uplink transmission is within the corresponding uplink BWP, the second set of configuration information takes effect.

[0051] Optionally, when the first frequency domain resource is not used for resource mapping of a downlink reference signal and / or a downlink channel, in the first time unit, the target frequency domain resource of the downlink reference signal and / or downlink channel is determined by the frequency domain resource configured or indicated by the network side device excluding the first frequency domain resource or excluding the first frequency domain resource and other frequency domain resources; in the third time unit, the target frequency domain resource of the downlink reference signal and / or downlink channel is determined by the frequency domain resource configured or indicated by the network side device. Among them, the other frequency domain resources may be frequency domain resources occupied by a protection bandwidth or a protection physical resource block (PRB). In this way, when the terminal operates in a downlink sub-band, the terminal can avoid receiving uplink signals / channel transmissions of other terminals according to the configuration of the first frequency domain resource. At the same time, the downlink channel / signal can be non-continuously mapped to multiple downlink sub-bands, and the size of the resource configuration / indication signaling of the downlink channel / signal does not need to change, thereby reducing the overhead of the terminal detecting resource configuration / indication signaling and improving the efficiency of downlink resource utilization.

[0052] In some embodiments, a network-side device such as a base station may configure frequency domain resources of a downlink reference signal / downlink channel of a terminal through higher-layer signaling.

[0053] In some other embodiments, a network-side device such as a base station may indicate the frequency domain resources of a downlink reference signal / downlink channel of a terminal through downlink control information (DCI).

[0054] Optionally, the first frequency domain resource is located within the downlink BWP of the terminal. For example, when the first frequency domain resource is not used for resource mapping of a downlink reference signal and / or a downlink channel, the first frequency domain resource is located within the downlink BWP of the terminal.

[0055] For example, taking a time slot as an example, a base station can indicate time slot information through signaling, where the time slot information includes a first time slot and a third time slot; wherein the first time slot is a time slot configured with a first frequency domain resource, and in the first time slot, the target frequency domain resource of the downlink reference signal and / or downlink channel is determined by the frequency domain resource configured or indicated by the network-side device, excluding the first frequency domain resource, or excluding the first frequency domain resource and other frequency domain resources; the third time slot is a downlink time slot, and in the third time slot, the target frequency domain resource of the downlink reference signal and / or downlink channel is determined by the frequency domain resource configured or indicated by the network-side device. For example, the type of the first time slot is a full-duplex time slot, in which the base station can perform uplink and downlink simultaneously; but the terminal is half-duplex, and if the terminal is transmitting downlink in the first time slot, the terminal can only receive channels / signals within the downlink sub-band frequency domain range. The configuration method of this embodiment can prevent the terminal from receiving uplink transmissions of other terminals, and can also achieve non-contiguous resource mapping of downlink channels / signals across multiple downlink sub-bands, thereby improving resource allocation efficiency. The type of the third time slot is a half-duplex time slot, and the base station can only perform uplink or downlink in the half-duplex time slot.

[0056] Optionally, in the first time unit, that is, when the target frequency domain resource of the downlink reference signal and / or downlink channel is determined by excluding the first frequency domain resource or excluding the first frequency domain resource and other frequency domain resources by the frequency domain resource configured or indicated by the network side device, the frequency domain position of the downlink reference signal and / or downlink channel is determined based on at least one of the following: the starting RB and bandwidth of the frequency domain resource configured or indicated by the network side device, the starting RB of the first frequency domain resource, the bandwidth of the first frequency domain resource or the bandwidth of the first frequency domain resource and other frequency domain resources, and the frequency domain resource configuration granularity of the downlink reference signal and / or downlink channel. For example, this frequency domain resource configuration granularity can be understood as the number of consecutive RBs.

[0057] For example, considering that the downlink reference signal is configured according to a certain RB granularity, such as 4 PRBs, but the size of the first frequency domain resource is not necessarily a multiple of 4 PRBs. For a downlink reference signal with a configuration granularity of X RBs, if the frequency domain resources configured or indicated by the network side exclude the first frequency domain resource or exclude the first frequency domain resource and other frequency domain resources, the number of RBs remaining is not an integer multiple of X, then the frequency domain position of the downlink reference signal is changed from S1 to S2-S2mod(X), and from S2+B2+(S2+B2)mod(X) to S1+B1, as shown in Figure 3, to ensure that the frequency domain resource mapping rule and resource mapping granularity of the downlink reference signal are not changed. Wherein, mod is the remainder symbol, S1 is the starting RB position of the downlink reference signal configured or indicated by the network side, B1 is the bandwidth or frequency domain resource of the downlink reference signal configured or indicated by the network side, S2 is the starting RB position of the first frequency domain resource, and B2 is the bandwidth of the first frequency domain resource or the bandwidth of the first frequency domain resource plus other frequency domain resources.

[0058] Optionally, in the first time unit, that is, when the target frequency domain resources of the downlink reference signal and / or downlink channel are determined by the frequency domain resources configured or indicated by the network side device excluding the first frequency domain resources or excluding the first frequency domain resources and other frequency domain resources, the sequence index of the downlink reference signal and / or downlink channel is continuously mapped on the frequency domain resources configured or indicated by the network side device to ensure that different types of terminals can share resource configuration.

[0059] For example, the sequence index of the downlink reference signal is mapped to the resource element (RE) in sequence, and its reference point (k=0) is subcarrier 0 of CRB 0. The sequence index of the downlink reference signal is still incremented in sequence at the first resource position. As shown in Figure 3, the reference signal sequence indexes in the frequency domain resource range from S1 to S2-S2mod(X) are r(m1) to r(m2), the reference signal sequence indexes in the frequency domain range from S2-S2mod(X) to S2+B2+(S2+B2)mod(X) are r(m2+1) to r(m3), and the reference signal sequence indexes in the frequency domain range from S2+B2+(S2+B2)mod(X) to S1+B1 are r(m3+1) to r(m4). That is, the sequence index of the reference signal is always mapped continuously, but when the terminal receives non-continuous reference signals, its sequence is non-continuous. In this way, the existing old terminals in the network, that is, the terminals that do not have the ability to receive the first frequency domain configuration information, and the new terminals that have the ability to receive the first frequency domain configuration information can share the resource configuration of the reference signal (such as CSI-RS). Because their sequence mapping is the same, both are mapped with reference to subcarrier 0 of CRB 0. The network side does not need to configure different reference signals for terminals with different capabilities, saving resource overhead on the network side.

[0060] Please refer to FIG4 , which is a flowchart of a resource configuration method provided in an embodiment of the present application. The method is executed by a terminal. As shown in FIG4 , the method includes the following steps:

[0061] Step 41: The terminal receives first configuration information from the network side device; the first configuration information is used to configure a first frequency domain resource for the terminal, the first frequency domain resource is used for the uplink transmission of the terminal, and / or, the first frequency domain resource is not used for resource mapping of the downlink reference signal and / or downlink channel.

[0062] Here, the first frequency domain resource may be used for the uplink transmission of the terminal, or may not be used for resource mapping of the downlink reference signal and / or downlink channel, or may be used for both uplink transmission of the terminal and resource mapping of the downlink reference signal and / or downlink channel. That is, the first frequency domain resource may indicate the frequency domain resource position of the terminal uplink transmission, or may indicate the position of the downlink reference signal and / or downlink signal of the terminal that is not used for resource mapping, or may indicate the frequency domain resource position of the terminal uplink transmission and may be used to indicate the position of the downlink reference channel / downlink signal of the terminal that is not used for resource mapping. The first frequency domain resource may be located within the uplink BWP and / or downlink BWP of the terminal.

[0063] Optionally, the first configuration information includes: a starting RB and bandwidth of the first frequency domain resource. For example, the starting RB is CRB 0.

[0064] In this way, the first frequency domain resource configured in the embodiment of the present application for uplink transmission of the terminal can be configured in the uplink BWP of the terminal, so that when the terminal switches from the uplink sub-band of the first frequency domain resource to the uplink BWP, there is no need to perform RF switching and BWP switching, but only adjust the configuration parameters, which can avoid communication interruption; and the first frequency domain resource configured in the embodiment of the present application that is not used for resource mapping of downlink reference signals and / or downlink channels can be configured in the downlink BWP of the terminal, so that the terminal can always work in one downlink BWP, realizing downlink reference signal / downlink channel mapping on multiple non-continuous downlink sub-bands, and the base station does not need to configure multiple sets of downlink reference signals / downlink channels for the terminal on multiple downlink sub-bands, thereby efficiently performing resource configuration.

[0065] Optionally, the resource configuration method in this embodiment further includes:

[0066] The terminal receives first information from a network-side device; the first information is used to configure or indicate time unit information of the terminal, and the time unit information includes at least one of the following: a first time unit, a second time unit, or a third time unit; the first time unit is a time unit configured with the first frequency domain resource, the second time unit is an uplink time unit, and the third time unit is a downlink time unit. In this way, efficient uplink and downlink transmission can be performed in combination with the configured first frequency domain resource.

[0067] Furthermore, when the first frequency domain resource is used for the uplink transmission of the terminal, in the first time unit, the uplink transmission of the terminal is within the first frequency domain resource, that is, the terminal performs uplink transmission within the first frequency domain resource; in the second time unit, the uplink transmission of the terminal is within the uplink bandwidth part BWP, that is, the terminal performs uplink transmission within the uplink BWP.

[0068] Optionally, the first frequency domain resource is located within the uplink BWP of the terminal. For example, when the first frequency domain resource is used for uplink transmission of the terminal, the first frequency domain resource is located within the uplink BWP of the terminal. In this way, the terminal can always operate within the uplink BWP, so that the terminal can switch between the first time unit and the second time unit without any interruption.

[0069] Optionally, the resource configuration method in this embodiment further includes:

[0070] The terminal receives two sets of configuration information from the network-side device; the two sets of configuration information include a first set of configuration information for uplink channels and / or uplink signals, and a second set of configuration information for the uplink BWP. The first set of configuration information is used for the first frequency domain resource, and the second set of configuration information is used for the uplink BWP. In this way, the terminal can switch from operating in the uplink subband of the first frequency domain resource to operating in the uplink BWP by simply adjusting the configuration parameters.

[0071] Furthermore, in the first time unit, that is, when the terminal's uplink transmission is within the first frequency domain resource, the first set of configuration information takes effect; in the second time unit, that is, when the terminal's uplink transmission is within the corresponding uplink BWP, the second set of configuration information takes effect.

[0072] Optionally, when the first frequency domain resource is not used for resource mapping of a downlink reference signal and / or a downlink channel, in the first time unit, the target frequency domain resource of the downlink reference signal and / or downlink channel is determined by the frequency domain resource configured or indicated by the network side device excluding the first frequency domain resource or excluding the first frequency domain resource and other frequency domain resources; in the third time unit, the target frequency domain resource of the downlink reference signal and / or downlink channel is determined by the frequency domain resource configured or indicated by the network side device. Among them, the other frequency domain resources may be frequency domain resources occupied by a protection bandwidth or a protection physical resource block (PRB). In this way, when the terminal operates in a downlink sub-band, the terminal can avoid receiving uplink signals / channel transmissions of other terminals according to the configuration of the first frequency domain resource. At the same time, the downlink channel / signal can be non-continuously mapped to multiple downlink sub-bands, and the size of the resource configuration / indication signaling of the downlink channel / signal does not need to change, thereby reducing the overhead of the terminal detecting resource configuration / indication signaling and improving the efficiency of downlink resource utilization.

[0073] Optionally, the first frequency domain resource is located within the downlink BWP of the terminal. For example, when the first frequency domain resource is not used for resource mapping of a downlink reference signal and / or a downlink channel, the first frequency domain resource is located within the downlink BWP of the terminal.

[0074] Optionally, in the first time unit, that is, when the target frequency domain resource of the downlink reference signal and / or downlink channel is determined by excluding the first frequency domain resource or excluding the first frequency domain resource and other frequency domain resources by the frequency domain resource configured or indicated by the network side device, the frequency domain position of the downlink reference signal and / or downlink channel is determined based on at least one of the following: the starting RB and bandwidth of the frequency domain resource configured or indicated by the network side device, the starting RB of the first frequency domain resource, the bandwidth of the first frequency domain resource or the bandwidth of the first frequency domain resource and other frequency domain resources, and the frequency domain resource configuration granularity of the downlink reference signal and / or downlink channel. For example, this frequency domain resource configuration granularity can be understood as the number of consecutive RBs.

[0075] Optionally, in the first time unit, that is, when the target frequency domain resources of the downlink reference signal and / or downlink channel are determined by the frequency domain resources configured or indicated by the network side device excluding the first frequency domain resources or excluding the first frequency domain resources and other frequency domain resources, the sequence index of the downlink reference signal and / or downlink channel is continuously mapped on the frequency domain resources configured or indicated by the network side device to ensure that different types of terminals can share resource configuration.

[0076] It should be noted that the resource configuration method provided in the embodiments of the present application can be executed by a resource configuration device or a control module in the resource configuration device for executing the resource configuration method. In the embodiments of the present application, the resource configuration device provided in the embodiments of the present application is described by taking the resource configuration device executing the resource configuration method as an example.

[0077] Please refer to FIG5 , which is a schematic diagram of the structure of a resource configuration device provided in an embodiment of the present application. The device is applied to a network-side device. As shown in FIG5 , the resource configuration device 50 includes:
