Description

Technical Field

[0001] This disclosure relates to the field of communications, and in particular to methods and apparatus for determining transmission behavior, and storage media. Background Technology

[0002] The Release-18 (Rel-18) full-duplex enhancement project will study full-duplex solutions, specifically enabling the network to simultaneously receive and send data within a single time slot.

[0003] If an uplink subband (UL subband) is configured on a downlink symbol (DL symbol), the terminal can only receive downlink data outside the range of the downlink subband (DL subband). However, in reality, uplink transmission may not necessarily exist within the UL subband. If there is no uplink transmission within the UL subband, the terminal still cannot receive downlink data within the frequency domain of the UL subband, thus greatly limiting or even degrading the terminal's transmission performance.

[0107] Exemplary embodiments will now be described in detail, examples of which are illustrated in the accompanying drawings. When the following description relates to the drawings, unless otherwise indicated, the same numerals in different drawings denote the same or similar elements. The embodiments described in the following exemplary embodiments do not represent all embodiments consistent with the present invention. Rather, they are merely examples of apparatuses and methods consistent with some aspects of the invention as detailed in the appended claims.

[0108] The terminology used in this disclosure is for the purpose of describing particular embodiments only and is not intended to be limiting of the disclosure. The singular forms “a,” “the,” and “the” as used in this disclosure and the appended claims are also intended to include the plural forms unless the context clearly indicates otherwise. It should also be understood that the term “and / or” as used herein refers to and includes any or all possible combinations of at least one associated listed item.

[0109] It should be understood that although the terms first, second, third, etc., may be used in this disclosure to describe various information, such information should not be limited to these terms. These terms are used only to distinguish information of the same type from one another. For example, without departing from the scope of this disclosure, first information may also be referred to as second information, and similarly, second information may also be referred to as first information. Depending on the context, the word "if" as used herein may be interpreted as "when," "when," or "in response to determination."

[0110] The 3rd Generation Partnership Project (3GPP) has reached a consensus to support full-duplex operation on at least semi-static flexible symbols and semi-static downlink symbols.

[0111] Among them, "flexible symbol" refers to a symbol whose transmission direction is flexible, and "downlink symbol" refers to a symbol whose transmission direction is downlink.

[0112] Specifically, as one implementation method, the following restrictions are imposed on the behavior of the terminal during full-duplex communication:

[0113] The terminal can only perform uplink transmission within the frequency domain of the UL subband;

[0114] The terminal can only perform downlink transmission within the frequency domain of the DL subband.

[0115] Specifically, after the base station configures the UL subband for the terminal on the DL symbol or flexible symbol, the terminal's corresponding behavior is as follows:

[0116] The terminal performs uplink transmission within the UL subband frequency domain.

[0117] The terminal performs downlink reception in the DL subband frequency domain, which is outside the UL subband.

[0118] In the above manner, if there is no uplink transmission within the UL subband, the terminal still cannot receive downlink data within the frequency domain of the UL subband, which greatly limits or even degrades the terminal's transmission performance.

[0119] To address the aforementioned technical problems, this disclosure provides the following method, apparatus, and storage medium for determining transmission behavior, which optimizes resource allocation and improves transmission performance during full-duplex communication.

[0120] The following section will first introduce the method for determining transmission behavior provided in this disclosure from the perspective of the terminal side. It should be noted that the terminal in this disclosure may include, but is not limited to, a Seamless Bidirectional Forwarding Detection (SBFD) aware terminal. It can be understood that an SBFD aware terminal is a terminal that supports full-duplex communication.

[0121] This disclosure provides a method for determining transmission behavior, referring to... Figure 1 As shown, Figure 1 This is a flowchart illustrating a method for determining transmission behavior according to an embodiment, which can be executed by a terminal. The method may include the following steps:

[0122] In step 101, the state of the subband is determined based on the information of the active partial bandwidth (BWP).

[0123] In this embodiment of the disclosure, the sub-band is located within a first time unit in the time domain, and the first transmission direction of the first time unit is opposite to the second transmission direction of the sub-band or the first transmission direction is flexible.

[0124] For example, the subband is an uplink subband located within a downlink time unit in the time domain, or the subband is a downlink subband located within an uplink time unit in the time domain.

[0125] For example, the subband may be an uplink subband located in a flexible time unit in the time domain, or the subband may be a downlink subband located in a flexible time unit in the time domain.

[0126] The first time unit in this disclosure can be a slot, a symbol, a duration (span), etc., and this disclosure does not limit this. A span includes multiple consecutive symbols.

[0127] In this embodiment of the disclosure, the base station can configure multiple available BWPs for the terminal, and the activated BWP is the BWP that is in an active state among the multiple available BWPs. The multiple available BWPs include multiple available uplink BWPs and / or multiple available downlink BWPs. The activated BWP can be either the uplink BWP that is in an active state among the multiple available uplink BWPs, or the downlink BWP that is in an active state among the multiple available downlink BWPs.

[0128] In the embodiments disclosed herein, the information for activating the BWP may include, but is not limited to, the activation BWP identifier, the frequency domain resource range of the activation BWP, etc., and this disclosure does not limit it.

[0129] In this embodiment of the disclosure, the state of the sub-band includes, but is not limited to, an active state and a deactivated state.

[0130] In one example, the subband is active, and the terminal can confirm that the subband's configuration information is in effect.

[0131] In another example, the subband is in an inactive state, and the terminal can ignore the subband's configuration information.

[0132] In step 102, a first transmission behavior is determined based on the state of the sub-band.

[0133] In this embodiment of the disclosure, the first transmission behavior refers to the transmission behavior of the terminal transmitting information.

[0134] In this embodiment of the disclosure, the information transmitted by the terminal includes, but is not limited to, data, signals, and channels, wherein the signals include, but are not limited to, reference signals (RS), and the channels include, but are not limited to, physical channels and logical channels.

[0135] In one example, the sub-band is active, and the terminal can perform a first transmission action according to the frequency domain resource range occupied by the sub-band. The determined first transmission action may include the transmission action performed on the first resource according to the second transmission direction. The first resource is located within the first time unit in the time domain and within the frequency domain range occupied by the sub-band in the frequency domain.

[0136] For example, the second transmission direction is uplink, where the terminal performs information transmission on the first resource. This information includes, but is not limited to, data, signals, and channels.

[0137] For example, in the second transmission direction, which is downlink, the terminal performs information reception on the first resource. This information includes, but is not limited to, data, signals, and channels.

[0138] Additionally, the terminal can also determine that the first transmission behavior includes transmission behavior performed on the second resource based on a time division multiplexing (TDD) structure configured or indicated by the base station. The second resource is located within the first time unit in the time domain and outside the frequency range occupied by the sub-band in the frequency domain.

[0139] For example, based on the TDD structure, the first transmission direction of the first time unit is determined to be downlink, and the terminal performs data reception on the second resource.

[0140] For example, if the first transmission direction of the first time unit is determined to be flexible based on the TDD structure, the base station further indicates that the first transmission direction of the first time unit is downlink through a slot format indicator (SFI) or other TDD structure indication information, and then the terminal performs data reception on the second resource.

[0141] In another example, the subband is in a deactivated state, and the terminal can ignore the subband configuration information and determine the first transmission behavior according to the TDD structure configured or indicated by the base station. The determined first transmission behavior may include the transmission behavior performed on the first time unit based on the time division multiplexing TDD structure configured or indicated by the base station.

[0142] For example, based on the TDD structure, the first transmission direction of the first time unit is determined to be downlink, and the terminal performs data reception on the third resource. The third resource is located within the first time unit in the time domain, and in the frequency domain, it can be located within the frequency domain resources occupied by the sub-band, or it can be located outside the frequency domain resources occupied by the sub-band.

[0143] For example, if the first transmission direction of the first time unit is determined to be flexible based on the TDD structure, and the base station further indicates that the first transmission direction of the first time unit is downlink through SFI or other TDD structure indication information, then the terminal performs data reception on the third resource. Here, the third resource is located within the first time unit in the time domain, and in the frequency domain, it can be located within the frequency domain resources occupied by the sub-band, or it can be located outside the frequency domain resources occupied by the sub-band.

[0144] The above is merely an illustrative example. Any scheme that determines the terminal's first transmission behavior based on the sub-band's state should fall within the protection scope of this disclosure.

[0145] In the above embodiments, the terminal can determine the state of the subband based on the relevant information of the activated BWP. The subband is located within a first time unit in the time domain, and the first transmission direction of the first time unit is opposite to the second transmission direction of the subband, or the first transmission direction is flexible. Furthermore, the terminal can determine its first transmission behavior based on the state of the subband. This optimizes resource allocation and improves transmission performance during full-duplex communication.

[0146] In some alternative embodiments, refer to Figure 2 As shown, Figure 2 This is a flowchart illustrating a method for determining transmission behavior according to an embodiment, which can be executed by a terminal. The method may include the following steps:

[0147] In step 201, the associated BWP identifier of the subband is determined.

[0148] In this embodiment of the disclosure, the sub-band is located within a first time unit in the time domain, and the first transmission direction of the first time unit is opposite to the second transmission direction of the sub-band or the first transmission direction is flexible.

[0149] For example, the subband is an uplink subband located within a downlink time unit in the time domain, or the subband is a downlink subband located within an uplink time unit in the time domain.

[0150] For example, the subband may be an uplink subband located in a flexible time unit in the time domain, or the subband may be a downlink subband located in a flexible time unit in the time domain.

[0151] The first time unit in this disclosure can be a slot, a symbol, a duration (span), etc., and this disclosure does not limit this. A span includes multiple consecutive symbols.

[0152] In this embodiment of the disclosure, the process of the terminal determining the associated BWP identifier may include: first determining the associated BWPs that are associated with the subband, and then determining the identifier of the associated BWP. In this embodiment of the disclosure, the associated BWPs of the subband satisfy the following conditions:

[0153] The frequency domain resources occupied by the associated BWP associated with the sub-band overlap with the frequency domain resources occupied by the sub-band. That is, the frequency domain resources occupied by the associated BWP include at least one resource block (RB) belonging to the sub-band.

[0154] In this embodiment of the disclosure, the uplink subband is associated with the uplink BWP, and the downlink subband is associated with the downlink BWP.

[0155] In one example, the associated BWP can be a BWP whose BWP index value meets a preset condition among multiple BWPs configured by the base station for the terminal.

[0156] The preset conditions can be maximum or minimum, and this disclosure does not limit them.

[0157] That is, the terminal determines the BWP with the smallest index value among the above multiple BWPs as the associated BWP of this subband.

[0158] Alternatively, the terminal may identify the BWP with the largest index value among the aforementioned BWPs as the associated BWP for that subband, and thus determine the associated BWP identifier.

[0159] In one example, the associated BWP can be the initial BWP.

[0160] The initial BWP can be a BWP configured by the base station for the terminal via system messages, used for the terminal's initial access to the base station. The initial BWP can include an initial uplink BWP and an initial downlink BWP.

[0161] In one example, the associated BWP could be the first BWP to be activated.

[0162] The first activated BWP can be the first BWP that is active among the multiple available BWPs configured by the base station for the terminal.

[0163] For example, the associated BWP of an uplink subband can be the first activated uplink BWP.

[0164] For example, the associated BWP of a downlink subband can be the first activated downlink BWP.

[0165] In this disclosed embodiment, the terminal may determine the associated BWP using, but is not limited to, the following methods:

[0166] In one example, the terminal can determine the associated BWP based on protocol agreements.

[0167] For example, if the protocol stipulates that the associated BWP is the initial BWP, then the terminal can determine the initial BWP as the associated BWP according to the protocol.

[0168] For example, if the agreement stipulates that the associated BWP is the BWP that is activated for the first time, the terminal will identify the BWP that is activated for the first time as the associated BWP in accordance with the agreement.

[0169] For example, if the protocol stipulates that the associated BWP is the BWP with the largest or smallest BWP index value among the multiple BWPs configured by the base station for the terminal, then the terminal, according to the protocol, determines the BWP with the largest or smallest BWP index value among the multiple BWPs (i.e., the multiple available BWPs configured by the base station for the terminal) as the associated BWP of the subband.

[0170] In another example, the terminal can receive signaling sent by the base station and determine the associated BWP based on the indication information carried in the signaling.

[0171] The signaling includes, but is not limited to, any of the following: Radio Resource Control (RRC) signaling; system messages; Media Access Control Element (MAC CE).

[0172] System messages include, but are not limited to, System Information Block (SIB) messages. For example, the SIB message can be an SIBn message, where n is a positive integer.

[0173] For example, the indication information directly indicates the BWP associated with the subband.

[0174] Optionally, the indication information can directly indicate the associated BWP identifier. For example, if the indication information indicates that the BWP index value is 2, then the terminal determines that the associated BWP identifier for this subband is 2. In this embodiment of the present disclosure, the base station can also implicitly indicate the associated BWP identifier through signaling. For example, the terminal can pre-determine the correspondence between different indication information contents and different BWP identifiers, and then, based on this correspondence, determine the BWP identifier corresponding to the indication information content carried in the signaling sent by the base station, and determine that BWP identifier as the associated BWP identifier.

[0175] Optionally, the indication information may indicate that the associated BWP is an initial BWP, or the indication information may also indicate that the BWP index value meets preset conditions, or the indication information may indicate that the associated BWP is a newly activated BWP. This disclosure does not limit this.

[0176] In another example, the terminal can determine whether it has received the aforementioned signaling from the base station. Upon receiving the signaling, it can determine the associated BWP based on the indication information carried in the signaling.

[0177] If the terminal does not receive the above signaling, the terminal can determine the associated BWP based on the protocol agreement.

[0178] In this embodiment of the disclosure, after the terminal determines the associated BWP, it can determine the identifier of the associated BWP. Optionally, the index value of the associated BWP can be used as the identifier of the associated BWP.

[0179] In this embodiment of the disclosure, in addition to determining the associated BWP first and then determining the associated BWP identifier, the terminal can also directly determine the associated BWP identifier.

[0180] In one example, the indication information sent by the base station indicates the identifier of the BWP that the terminal activates for the first time, such as firstActiveDownlinkBWP-id. Based on this indication information, the terminal can identify the BWP corresponding to firstActiveDownlinkBWP-id as the first activated downlink BWP. Alternatively, it can directly identify firstActiveDownlinkBWP-id as the associated BWP identifier based on this indication information. That is, the terminal can directly determine the associated BWP identifier based on the first activated BWP as the associated BWP of the subband.

[0181] In another example, the base station configures an initial BWP identifier for the terminal using indication information. The terminal can determine the BWP corresponding to this initial BWP identifier as the initial BWP based on this indication information. Alternatively, it can directly determine the initial BWP identifier as the associated BWP identifier based on this indication information. That is, the terminal can directly determine the associated BWP identifier based on the initial BWP as the associated BWP of the subband.

[0182] The above is merely an illustrative example. Any other methods used by the terminal to determine the associated BWP and thus the associated BWP identifier, or any method that directly determines the associated BWP identifier, should fall within the scope of protection of this disclosure.

[0183] In step 202, in response to the activation BWP identifier being the same as the associated BWP identifier, it is determined that the subband is in an active state.

[0184] In this embodiment of the disclosure, the base station can configure multiple available BWPs for the terminal, and the activated BWP is the BWP that is in an active state among the multiple available BWPs. The multiple available BWPs include multiple available uplink BWPs and / or multiple available downlink BWPs. The activated BWP can be either the uplink BWP that is in an active state among the multiple available uplink BWPs, or the downlink BWP that is in an active state among the multiple available downlink BWPs.

[0185] In this embodiment of the disclosure, when the activated BWP identifier is the same as the associated BWP identifier, the terminal determines that the subband is in an active state.

[0186] In step 203, in response to the fact that the activated BWP identifier is different from the associated BWP identifier, it is determined that the subband is in a deactivated state.

[0187] In this embodiment of the disclosure, when the activated BWP identifier is different from the associated BWP identifier, the terminal determines that the subband is in a deactivated state.

[0188] In step 204, a first transmission behavior is determined based on the state of the sub-band.

[0189] The implementation of step 204 is similar to that of step 102 above, and will not be repeated here.

[0190] In the above embodiments, the terminal can determine the state of the subband based on whether the activated BWP identifier and the associated BWP identifier are the same. The subband is located within a first time unit in the time domain, and the first transmission direction of the first time unit is opposite to the second transmission direction of the subband, or the first transmission direction is flexible. Furthermore, the terminal can determine its first transmission behavior based on the state of the subband. This optimizes resource allocation and improves transmission performance during full-duplex communication.

[0191] In some alternative embodiments, refer to Figure 3 As shown, Figure 3 This is a flowchart illustrating a method for determining transmission behavior according to an embodiment, which can be executed by a terminal. The method may include the following steps:

[0192] In step 301, the state of the sub-band is determined based on the frequency domain resources occupied by the activated BWP and the frequency domain resources occupied by the sub-band.

[0193] In this embodiment of the disclosure, the sub-band is located within a first time unit in the time domain, and the first transmission direction of the first time unit is opposite to the second transmission direction of the sub-band or the first transmission direction is flexible.

[0194] For example, the subband is an uplink subband located within a downlink time unit in the time domain, or the subband is a downlink subband located within an uplink time unit in the time domain.

[0195] For example, the subband may be an uplink subband located in a flexible time unit in the time domain, or the subband may be a downlink subband located in a flexible time unit in the time domain.

[0196] The first time unit in this disclosure can be a slot, a symbol, a duration (span), etc., and this disclosure does not limit this. A span includes multiple consecutive symbols.

[0197] In this embodiment of the disclosure, the base station can configure multiple available BWPs for the terminal, and the activated BWP is the BWP that is in an active state among the multiple available BWPs. The multiple available BWPs include multiple available uplink BWPs and / or multiple available downlink BWPs. The activated BWP can be either the uplink BWP that is in an active state among the multiple available uplink BWPs, or the downlink BWP that is in an active state among the multiple available downlink BWPs.

[0198] In one example, if all the frequency domain resources occupied by the sub-band are within the frequency domain resources occupied by the active BWP, the terminal determines that the sub-band is in an active state. If some of the frequency domain resources occupied by the sub-band are outside the frequency domain resources occupied by the active BWP, the sub-band is determined to be in a deactivated state.

[0199] In another example, the terminal determines the number of first resource blocks (RBs), wherein the first RB is an RB that is simultaneously located within the frequency domain resource range occupied by the active BWP and the frequency domain resource range occupied by the subband, that is, the first RB is an RB shared by the subband and the active BWP.

[0200] If the number of first RBs is greater than or equal to a preset number, the terminal determines that the subband is in an active state. If the number of first RBs is less than the preset number, the terminal determines that the subband is in a deactivated state.

[0201] The preset number can be agreed upon by the protocol or configured by the base station, and this disclosure does not limit it.

[0202] In step 302, a first transmission behavior is determined based on the state of the sub-band.

[0203] The implementation of step 302 is similar to that of step 102 above, and will not be repeated here.

[0204] In the above embodiments, the terminal can determine the state of the sub-band based on the frequency domain resources occupied by the activated BWP and the frequency domain resources occupied by the sub-band. The sub-band is located within a first time unit in the time domain, and the first transmission direction of the first time unit is opposite to the second transmission direction of the sub-band, or the first transmission direction is flexible. Furthermore, the terminal can determine its first transmission behavior based on the state of the sub-band. This optimizes resource allocation and improves transmission performance during full-duplex communication.

[0205] The following section describes the method for determining transmission behavior provided in this disclosure from the perspective of the base station.

[0206] This disclosure provides a method for determining transmission behavior, referring to... Figure 4 As shown, Figure 4 This is a flowchart illustrating a method for determining transmission behavior according to an embodiment, which can be executed by a base station. The method may include the following steps:

[0207] In step 401, the state of the subband configured for the terminal is determined based on the information of the activated partial bandwidth (BWP).

[0208] In this embodiment of the disclosure, the sub-band is located within a first time unit in the time domain, and the first transmission direction of the first time unit is opposite to the second transmission direction of the sub-band or the first transmission direction is flexible.

[0209] For example, the subband is an uplink subband located within a downlink time unit in the time domain, or the subband is a downlink subband located within an uplink time unit in the time domain.

[0210] For example, the subband may be an uplink subband located in a flexible time unit in the time domain, or the subband may be a downlink subband located in a flexible time unit in the time domain.

[0211] The first time unit in this disclosure can be a slot, a symbol, a duration (span), etc., and this disclosure does not limit this. A span includes multiple consecutive symbols.

[0212] In this embodiment of the disclosure, the base station can configure multiple available BWPs for the terminal, and the activated BWP is the BWP that is in an active state among the multiple available BWPs. The multiple available BWPs include multiple available uplink BWPs and / or multiple available downlink BWPs. The activated BWP can be either the uplink BWP that is in an active state among the multiple available uplink BWPs, or the downlink BWP that is in an active state among the multiple available downlink BWPs.

[0213] In the embodiments disclosed herein, the information for activating the BWP may include, but is not limited to, the activation BWP identifier, the frequency domain resource range of the activation BWP, etc., and this disclosure does not limit it.

[0214] In this embodiment of the disclosure, the state of the sub-band includes, but is not limited to, an active state and a deactivated state.

[0215] In one example, the subband is active, and the base station can determine that the subband configuration information for the terminal is effective.

[0216] In another example, the subband is in a deactivated state, and the base station can determine that the terminal ignores the subband's configuration information.

[0217] In step 402, a second transmission behavior is determined based on the state of the sub-band.

[0218] In this embodiment of the disclosure, the second transmission behavior refers to the transmission behavior of the base station transmitting information. The second transmission behavior corresponds to the first transmission behavior.

[0219] For example, if the first transmission action performed by the terminal includes receiving information, then the second transmission action performed by the base station includes sending information.

[0220] For example, if the first transmission action performed by the terminal includes sending information, then the second transmission action performed by the base station includes receiving information.

[0221] In this embodiment of the disclosure, the information transmitted by the base station includes, but is not limited to, data, signals, and channels, wherein the signals include, but are not limited to, RS, and the channels include, but are not limited to, physical channels and logical channels.

[0222] In one example, the sub-band is active, and the base station can perform a second transmission action according to the frequency domain resource range occupied by the sub-band. The determined second transmission action can include the transmission action performed on the first resource according to the second transmission direction. The first resource is located within the first time unit in the time domain and within the frequency domain range occupied by the sub-band in the frequency domain.

[0223] For example, the second transmission direction is uplink, and the base station performs information reception on the first resource. This information includes, but is not limited to, data, signals, and channels.

[0224] For example, in the second transmission direction, which is downlink, the base station performs information transmission on the first resource. This information includes, but is not limited to, data, signals, and channels.

[0225] Additionally, the base station can determine that the second transmission behavior includes transmission behavior performed on the second resource based on the TDD structure configured or indicated for the terminal. The second resource is located within the first time unit in the time domain and outside the frequency range occupied by the sub-band in the frequency domain.

[0226] For example, based on the TDD structure, the first transmission direction of the first time unit is determined to be downlink, and the base station performs data transmission on the second resource.

[0227] For example, if the first transmission direction of the first time unit is determined to be flexible based on the TDD structure, the base station can further indicate that the first transmission direction of the first time unit is downlink through SFI or other TDD structure indication information, and then the base station will perform data transmission on the second resource.

[0228] In another example, the subband is in a deactivated state. The base station can determine that the terminal ignores the subband's configuration information and determine a second transmission behavior according to the TDD structure configured or indicated for the terminal. The determined second transmission behavior can include the transmission behavior performed on the first time unit based on the time division multiplexing TDD structure configured or indicated for the terminal.

[0229] For example, based on the TDD structure, the first transmission direction of the first time unit is determined to be downlink, and the base station performs data transmission on the third resource. The third resource is located within the first time unit in the time domain, and in the frequency domain, it can be located within the frequency domain resources occupied by the sub-band, or it can be located outside the frequency domain resources occupied by the sub-band.

[0230] For example, if the first transmission direction of the first time unit is determined to be flexible based on the TDD structure, and the base station further indicates that the first transmission direction of the first time unit is downlink through SFI or other TDD structure indication information, then the base station performs data transmission on the third resource. The third resource is located within the first time unit in the time domain, and in the frequency domain, it can be located within or outside the frequency domain resources occupied by the sub-band.

[0231] The above is merely an illustrative example. Any scheme that determines the second transmission behavior of a base station based on the state of a sub-band should fall within the protection scope of this disclosure.

[0232] In the above embodiments, the base station can determine the state of the sub-band based on the relevant information of the activated BWP. The sub-band is located within a first time unit in the time domain, and the first transmission direction of the first time unit is opposite to the second transmission direction of the sub-band, or the first transmission direction is flexible. Furthermore, the base station can determine its own second transmission behavior based on the state of the sub-band. This optimizes resource allocation and helps improve transmission performance during full-duplex communication.

[0233] In some alternative embodiments, refer to Figure 5 As shown, Figure 5 This is a flowchart illustrating a method for determining transmission behavior according to an embodiment, which can be executed by a base station. The method may include the following steps:

[0234] In step 501, the associated BWP identifier of the subband is determined.

[0235] In this embodiment of the disclosure, the sub-band is located within a first time unit in the time domain, and the first transmission direction of the first time unit is opposite to the second transmission direction of the sub-band or the first transmission direction is flexible.

[0236] For example, the subband is an uplink subband located within a downlink time unit in the time domain, or the subband is a downlink subband located within an uplink time unit in the time domain.

[0237] For example, the subband may be an uplink subband located in a flexible time unit in the time domain, or the subband may be a downlink subband located in a flexible time unit in the time domain.

[0238] The first time unit in this disclosure can be a slot, a symbol, a duration (span), etc., and this disclosure does not limit this. A span includes multiple consecutive symbols.

[0239] In this embodiment of the disclosure, the process of a base station determining the associated BWP identifier may include: first determining the associated BWP that has an association relationship with the subband, and then determining the identifier of the associated BWP.

[0240] In this embodiment of the disclosure, the associated BWP of the subband satisfies the following conditions:

[0241] The frequency domain resources occupied by the associated BWP associated with the sub-band overlap with the frequency domain resources occupied by the sub-band. That is, the frequency domain resources occupied by the associated BWP include at least one RB belonging to the sub-band.

[0242] In this embodiment of the disclosure, the uplink subband is associated with the uplink BWP, and the downlink subband is associated with the downlink BWP.

[0243] In one example, the associated BWP can be a BWP whose BWP index value meets a preset condition among multiple BWPs configured for the terminal.

[0244] The preset conditions can be maximum or minimum, and this disclosure does not limit them.

[0245] That is, the base station determines the BWP with the smallest index value among the above multiple BWPs as the associated BWP of that subband.

[0246] Alternatively, the base station may identify the BWP with the largest index value among the aforementioned BWPs as the associated BWP for that subband, and thus determine the associated BWP identifier.

[0247] In one example, the associated BWP can be the initial BWP.

[0248] The initial BWP can be a BWP configured by the base station for the terminal via system messages, used for the terminal's initial access to the base station. The initial BWP can include an initial uplink BWP and an initial downlink BWP.

[0249] In one example, the associated BWP could be the first BWP to be activated.

[0250] The first activated BWP can be the first BWP that is active among the multiple available BWPs configured by the base station for the terminal.

[0251] For example, the associated BWP of an uplink subband can be the first activated uplink BWP.

[0252] For example, the associated BWP of a downlink subband can be the first activated downlink BWP.

[0253] In this embodiment of the disclosure, the base station may determine the associated BWP using, but is not limited to, the following methods:

[0254] In one example, the base station can determine the associated BWP based on protocol agreements.

[0255] For example, if the protocol stipulates that the associated BWP is the initial BWP, then the base station can determine the initial BWP as the associated BWP according to the protocol.

[0256] For example, if the agreement stipulates that the associated BWP is the BWP that is activated for the first time, the base station will determine the BWP that is activated for the first time as the associated BWP in accordance with the agreement.

[0257] For example, if the protocol stipulates that the associated BWP is the BWP with the largest or smallest BWP index value among the multiple BWPs configured by the base station for the terminal, then the base station, in accordance with the protocol, determines the BWP with the largest or smallest BWP index value among the multiple BWPs (i.e., the multiple available BWPs configured by the base station for the terminal) as the associated BWP of the subband.

[0258] In another example, the base station can send signaling to the terminal, indicating the associated BWP based on the indication information carried in the signaling.

[0259] The signaling includes, but is not limited to, any one of the following: RRC signaling; system messages; MAC CE.

[0260] System messages include, but are not limited to, SIB messages. For example, the SIB message can be an SIBn message, where n is a positive integer.

[0261] For example, the indication information directly indicates the BWP associated with the subband.

[0262] Optionally, the indication information can directly indicate the associated BWP identifier. For example, if the indication information indicates that the BWP index value is 2, then the base station indicates that the associated BWP identifier for this subband is 2.

[0263] In this embodiment of the disclosure, the base station can also implicitly indicate the association of BWP through signaling. For example, the base station determines the indication information content corresponding to the associated BWP based on the correspondence between different indication information content and different BWPs, and carries the corresponding indication information content in the signaling, and then sends the signaling to the terminal so that the terminal can determine the associated BWP based on the indication information content and the above correspondence.

[0264] Optionally, the indication information may indicate that the associated BWP is an initial BWP, or the indication information may also indicate that the BWP index value meets preset conditions, or the indication information may indicate that the associated BWP is a newly activated BWP. This disclosure does not limit this.

[0265] In another example, after sending the aforementioned signaling, the base station can determine that the terminal determines the associated BWP according to the indication information carried in the signaling. Alternatively, the base station can determine that the terminal determines the associated BWP based on the protocol agreement without sending signaling to the terminal.

[0266] In this embodiment of the disclosure, after the base station determines the associated BWP, it can determine the identifier of the associated BWP. Optionally, the index value of the associated BWP can be used as the identifier of the associated BWP.

[0267] In this embodiment of the disclosure, in addition to determining the associated BWP first and then determining the associated BWP identifier, the base station can also directly determine the associated BWP identifier.

[0268] In one example, the indication information sent by the base station indicates the identifier of the BWP that the terminal activates for the first time, such as firstActiveDownlinkBWP-id. This means that the base station informs the terminal of both the identifier of the downlink BWP that is activated for the first time and the identifier of the associated BWP through this indication information. The terminal identifies the BWP corresponding to firstActiveDownlinkBWP-id as the downlink BWP that is activated for the first time. Alternatively, the terminal can directly identify firstActiveDownlinkBWP-id as the identifier of the associated BWP based on this indication information.

[0269] In another example, the base station indicates the initial BWP identifier through indication information. The terminal can determine the BWP corresponding to the initial BWP identifier as the initial BWP based on the indication information. Alternatively, it can directly determine the initial BWP identifier as the associated BWP identifier based on the indication information.

[0270] The above is merely an illustrative example. Any other methods used by the base station to determine the associated BWP identifier should fall within the scope of this disclosure.

[0271] In step 502, in response to the activation BWP identifier being the same as the associated BWP identifier, it is determined that the subband is in an active state.

[0272] In this embodiment of the disclosure, the base station can configure multiple available BWPs for the terminal, and the activated BWP is the BWP that is in an active state among the multiple available BWPs. The multiple available BWPs include multiple available uplink BWPs and / or multiple available downlink BWPs. The activated BWP can be either the uplink BWP that is in an active state among the multiple available uplink BWPs, or the downlink BWP that is in an active state among the multiple available downlink BWPs.

[0273] In this embodiment of the disclosure, when the activated BWP identifier is the same as the associated BWP identifier, the base station determines that the subband is in an active state.

[0274] In step 503, in response to the fact that the activated BWP identifier is different from the associated BWP identifier, it is determined that the subband is in a deactivated state.

[0275] In this embodiment of the disclosure, when the activated BWP identifier is different from the associated BWP identifier, the base station determines that the subband is in a deactivated state.

[0276] In step 504, a second transmission behavior is determined based on the state of the sub-band.

[0277] The implementation of step 504 is similar to that of step 402 above, and will not be repeated here.

[0278] In the above embodiments, the base station can determine the state of the sub-band based on whether the activated BWP identifier and the associated BWP identifier are the same. The sub-band is located within a first time unit in the time domain, and the first transmission direction of the first time unit is opposite to the second transmission direction of the sub-band, or the first transmission direction is flexible. Furthermore, the base station can determine its second transmission behavior based on the state of the sub-band. This optimizes resource allocation and improves transmission performance during full-duplex communication.

[0279] In some alternative embodiments, refer to Figure 6 As shown, Figure 6 This is a flowchart illustrating a method for determining transmission behavior according to an embodiment, which can be executed by a base station. The method may include the following steps:

[0280] In step 601, the state of the sub-band is determined based on the frequency domain resources occupied by the activated BWP and the frequency domain resources occupied by the sub-band.

[0281] In this embodiment of the disclosure, the sub-band is located within a first time unit in the time domain, and the first transmission direction of the first time unit is opposite to the second transmission direction of the sub-band or the first transmission direction is flexible.

[0282] For example, the subband is an uplink subband located within a downlink time unit in the time domain, or the subband is a downlink subband located within an uplink time unit in the time domain.

[0283] For example, the subband may be an uplink subband located in a flexible time unit in the time domain, or the subband may be a downlink subband located in a flexible time unit in the time domain.

[0284] The first time unit in this disclosure can be a slot, symbol, span, etc., and this disclosure does not limit it. Among them, a span includes multiple consecutive symbols.

[0285] In this embodiment of the disclosure, the base station can configure multiple available BWPs for the terminal, and the activated BWP is the BWP that is in an active state among the multiple available BWPs. The multiple available BWPs include multiple available uplink BWPs and / or multiple available downlink BWPs. The activated BWP can be either the uplink BWP that is in an active state among the multiple available uplink BWPs, or the downlink BWP that is in an active state among the multiple available downlink BWPs.

[0286] In one example, if all the frequency domain resources occupied by the sub-band are within the frequency domain resources occupied by the active BWP, the base station determines that the sub-band is in an active state. If some of the frequency domain resources occupied by the sub-band are outside the frequency domain resources occupied by the active BWP, the base station determines that the sub-band is in a deactivated state.

[0287] In another example, the base station determines the number of first resource blocks (RBs), wherein the first RB is an RB that is simultaneously located within the frequency domain resource range occupied by the active BWP and the frequency domain resource range occupied by the sub-band, that is, the first RB is an RB shared by the sub-band and the active BWP.

[0288] If the number of first RBs is greater than or equal to a preset number, the base station determines that the subband is in an active state. If the number of first RBs is less than the preset number, the base station determines that the subband is in a deactivated state.

[0289] The preset number can be agreed upon by the protocol or configured by the base station, and this disclosure does not limit it.

[0290] In step 602, a second transmission behavior is determined based on the state of the sub-band.

[0291] The implementation of step 602 is similar to that of step 402 above, and will not be repeated here.

[0292] In the above embodiments, the base station can determine the state of a sub-band based on the frequency domain resources occupied by the activated BWP and the frequency domain resources occupied by the sub-band. The sub-band is located within a first time unit in the time domain, and the first transmission direction of the first time unit is opposite to the second transmission direction of the sub-band, or the first transmission direction is flexible. Furthermore, the base station can determine its second transmission behavior based on the state of the sub-band. This optimizes resource allocation and improves transmission performance during full-duplex communication.

[0293] To facilitate understanding of the above solutions, the present disclosure provides the following embodiments.

[0294] Example 1: Assume that the terminal is a full-duplex terminal, that is, the terminal can perform uplink transmission in the UL subband on the DL symbol or flexible symbol, or perform downlink reception in the DL subband on the UL symbol or flexible symbol.

[0295] Assume the base station performs full-duplex operation on the semi-static flexible symbol and / or semi-static symbol in the TDD band, i.e., simultaneously scheduling downlink and uplink data. In this embodiment, it is assumed that the semi-static flexible symbol and semi-static DL symbol are determined through the common TDD configuration (tdd-UL-DL-ConfigurationCommon) sent by the base station, or through tdd-UL-DL-ConfigurationCommon and terminal-specific TDD configuration (tdd-UL-DL-ConfigurationDedicated). The base station instructs the terminal on the UL subband on the semi-static flexible symbol and semi-static DL symbol in the following manner. Of course, the base station can instruct or configure the UL subband in other ways, or it can instruct or configure the DL subband; this embodiment does not impose any limitations.

[0296] The base station configures a UL subband for the terminal.

[0297] Within the UL subband, the terminal can only perform uplink transmissions;

[0298] Within the DL subband, the terminal can only perform downlink reception.

[0299] The base station performs data channel scheduling, configuration, or reference signal indication within the UL subband or DL ​​subband.

[0300] In this embodiment, it is assumed that the time slot structure configured by the base station through TDD UL-DL configuration is DDDFU, referring to... Figure 7A As shown, during the TDD configuration period, slots #0, #1, and #2 are DL slots, slot #3 is a flexible slot, and slot #4 is a UL slot. Of course, this embodiment can also be directly applied to other TDD ULDL time slot structures.

[0301] In this embodiment, it is assumed that the base station has configured UL subband for the terminal on slots #1, #2, and #3, referring to... Figure 7BAs shown. For simplicity, this embodiment does not consider the guard period or handover time between the DL symbol and the UL subband. Of course, the base station can be configured with other UL subbands without affecting the implementation of the scheme protected by this patent.

[0302] In this embodiment, it is assumed that the frequency domain resources of the UL subband cannot be used for DL ​​transmission. In order to enhance or protect downlink transmission performance and improve resource utilization, when there is no uplink transmission or the UL transmission is reduced in the UL subband, the base station can activate (disable) the UL subband through certain rules, thereby releasing the resources occupied by the UL subband and making them available for DL ​​transmission, thereby enhancing DL transmission performance.

[0303] In this embodiment, the base station and the terminal determine the associated BWP identifier of the subband through a protocol-agreed method, and determine whether the subband is in an active state by comparing the current active UL BWP identifier with the associated BWP identifier of the subband. The state of the subband is defined as follows:

[0304] The UL subband is active: The terminal, according to the UL subband configured or indicated by the base station, determines the first transmission behavior, including performing uplink transmission within the UL subband or downlink reception outside the UL subband. Further, this embodiment assumes that the terminal cannot receive downlink data within the UL subband range.

[0305] UL subband is in deactivated state: The terminal ignores the UL subband configured or indicated by the base station and determines the terminal's first transmission behavior according to the TDD structure configured or indicated by the base station.

[0306] For example, if a deactivated UL subband is located on a DL symbol, the SBFD aware terminal will assume that there is no UL subband on this DL symbol.

[0307] For example, if a UL subband in a deactivated state is located on a flexible symbol, the SBFDaware terminal will assume that there is no UL subband on this flexible symbol.

[0308] In this embodiment, the associated BWP identifier of the UL subband can be determined specifically through the following method, which is not limited in this patent:

[0309] The associated BWP is the BWP with the smallest index value among the multiple available BWPs configured by the base station for the terminal;

[0310] Alternatively, the associated BWP is the BWP with the largest index value among the multiple available BWPs configured by the base station for the terminal;

[0311] Alternatively, the associated BWP is the BWP with the firstActiveUplinkBWP-Id;

[0312] Alternatively, the associated BWP is the initial UL BWP.

[0313] Specifically, if the activated UL BWP identifier is the same as the associated BWP identifier, the UL subband is in an activated state; if the activated UL BWP identifier is different from the associated BWP identifier, the UL subband is in a deactivated state.

[0314] It should be noted that the frequency domain resources occupied by the associated BWP overlap with those occupied by the subband, that is, the associated BWP includes at least one RB belonging to the UL subband.

[0315] Example 2: Assume that the terminal is a full-duplex terminal, that is, the terminal can perform uplink transmission in the UL subband on the DL symbol or flexible symbol, or perform downlink reception in the DL subband on the UL symbol or flexible symbol.

[0316] Assume the base station performs full-duplex operation on the semi-static flexible symbol and / or semi-static symbol in the TDD band, i.e., simultaneously scheduling downlink and uplink data. In this embodiment, it is assumed that the semi-static flexible symbol and semi-static DL symbol are determined through the common TDD configuration (tdd-UL-DL-ConfigurationCommon) sent by the base station, or through tdd-UL-DL-ConfigurationCommon and terminal-specific TDD configuration (tdd-UL-DL-ConfigurationDedicated). The base station instructs the terminal on the UL subband on the semi-static flexible symbol and semi-static DL symbol in the following manner. Of course, the base station can instruct or configure the UL subband in other ways, or it can instruct or configure the DL subband; this embodiment does not impose any limitations.

[0317] The base station configures a UL subband for the terminal.

[0318] Within the UL subband, the terminal can only perform uplink transmissions;

[0319] Within the DL subband, the terminal can only perform downlink reception.

[0320] The base station performs data channel scheduling, configuration, or reference signal indication within the UL subband or DL ​​subband.

[0321] In this embodiment, it is assumed that the time slot structure configured by the base station through TDD UL-DL configuration is DDDFU, referring to... Figure 7A As shown, during the TDD configuration period, slots #0, #1, and #2 are DL slots, slot #3 is a flexible slot, and slot #4 is a UL slot. Of course, this embodiment can also be directly applied to other TDD ULDL time slot structures.

[0322] In this embodiment, it is assumed that the base station has configured UL subband for the terminal on slots #1, #2, and #3, referring to... Figure 7B As shown. For simplicity, this embodiment does not consider the guard period or handover time between the DL symbol and the UL subband. Of course, the base station can be configured with other UL subbands without affecting the implementation of the scheme protected by this patent.

[0323] In this embodiment, it is assumed that the frequency domain resources of the UL subband cannot be used for DL ​​transmission. In order to enhance or protect downlink transmission performance and improve resource utilization, when there is no uplink transmission or the UL transmission is reduced in the UL subband, the base station can activate (disable) the UL subband through certain rules, thereby releasing the resources occupied by the UL subband and making them available for DL ​​transmission, thereby enhancing DL transmission performance.

[0324] In this embodiment, the base station indicates the associated BWP identifier of the UL subband to the terminal via signaling, and determines whether the subband is active by comparing the active UL BWP identifier with the associated BWP identifier of the subband. The subband's state is defined as follows:

[0325] The UL subband is active: The terminal, according to the UL subband configured or indicated by the base station, determines the first transmission behavior, including performing uplink transmission within the UL subband or downlink reception outside the UL subband. Further, this embodiment assumes that the terminal cannot receive downlink data within the UL subband range.

[0326] UL subband is in deactivated state: The terminal ignores the UL subband configured or indicated by the base station and determines the terminal's first transmission behavior according to the TDD structure configured or indicated by the base station.

[0327] For example, if a deactivated UL subband is located on a DL symbol, the SBFD aware terminal will assume that there is no UL subband on this DL symbol.

[0328] For example, if a UL subband in a deactivated state is located on a flexible symbol, the SBFDaware terminal will assume that there is no UL subband on this flexible symbol.

[0329] The aforementioned signaling can be RRC signaling, or system messages such as SIB1, or MAC CE. This disclosure can carry indication information through the aforementioned signaling, which is used to indicate the associated BWP identifier. This embodiment does not impose any limitations.

[0330] Furthermore, when the base station does not configure or indicate the associated BWP identifier for the terminal, the terminal can determine the associated BWP identifier using the method agreed upon in the protocol. For details, please refer to Embodiment 1, which will not be repeated here.

[0331] It should be noted that the frequency domain resources occupied by the associated BWP overlap with those occupied by the subband, that is, the associated BWP includes at least one RB belonging to the UL subband.

[0332] Example 3: Assume that the terminal is a full-duplex terminal, that is, the terminal can perform uplink transmission in the UL subband on the DL symbol or flexible symbol, or perform downlink reception in the DL subband on the UL symbol or flexible symbol.

[0333] Assume the base station performs full-duplex operation on the semi-static flexible symbol and / or semi-static symbol in the TDD band, i.e., simultaneously scheduling downlink and uplink data. In this embodiment, it is assumed that the semi-static flexible symbol and semi-static DL symbol are determined through the common TDD configuration (tdd-UL-DL-ConfigurationCommon) sent by the base station, or through tdd-UL-DL-ConfigurationCommon and terminal-specific TDD configuration (tdd-UL-DL-ConfigurationDedicated). The base station instructs the terminal on the UL subband on the semi-static flexible symbol and semi-static DL symbol in the following manner. Of course, the base station can instruct or configure the UL subband in other ways, or it can instruct or configure the DL subband; this embodiment does not impose any limitations.

[0334] The base station configures a UL subband for the terminal.

[0335] Within the UL subband, the terminal can only perform uplink transmissions;

[0336] Within the DL subband, the terminal can only perform downlink reception.

[0337] The base station performs data channel scheduling, configuration, or reference signal indication within the UL subband or DL ​​subband.

[0338] In this embodiment, it is assumed that the time slot structure configured by the base station through TDD UL-DL configuration is DDDFU, referring to... Figure 7A As shown, during the TDD configuration period, slots #0, #1, and #2 are DL slots, slot #3 is a flexible slot, and slot #4 is a UL slot. Of course, this embodiment can also be directly applied to other TDD ULDL time slot structures.

[0339] In this embodiment, it is assumed that the base station has configured UL subband for the terminal on slots #1, #2, and #3, referring to... Figure 7BAs shown. For simplicity, this embodiment does not consider the guard period or handover time between the DL symbol and the UL subband. Of course, the base station can be configured with other UL subbands without affecting the implementation of the scheme protected by this patent.

[0340] In this embodiment, it is assumed that the frequency domain resources of the UL subband cannot be used for DL ​​transmission. In order to enhance or protect downlink transmission performance and improve resource utilization, when there is no uplink transmission or the UL transmission is reduced in the UL subband, the base station can activate (disable) the UL subband through certain rules, thereby releasing the resources occupied by the UL subband and making them available for DL ​​transmission, thereby enhancing DL transmission performance.

[0341] In this embodiment, the base station and the terminal determine whether the subband is active by activating the frequency domain resources occupied by the BWP and the frequency domain resources occupied by the subband. The state of the subband is defined as follows:

[0342] The UL subband is active: The terminal, according to the UL subband configured or indicated by the base station, determines the first transmission behavior, including performing uplink transmission within the UL subband or downlink reception outside the UL subband. Further, this embodiment assumes that the terminal cannot receive downlink data within the UL subband range.

[0343] UL subband is in deactivated state: The terminal ignores the UL subband configured or indicated by the base station and determines the terminal's first transmission behavior according to the TDD structure configured or indicated by the base station.

[0344] For example, if a deactivated UL subband is located on a DL symbol, the SBFD aware terminal will assume that there is no UL subband on this DL symbol.

[0345] For example, if a UL subband in a deactivated state is located on a flexible symbol, the SBFDaware terminal will assume that there is no UL subband on this flexible symbol.

[0346] In this embodiment, it is assumed that the base station has configured two BWPs for the terminal, referring to... Figure 7CAs shown, for ease of description, it is assumed that the frequency domain resources occupied by BWP#1 are RB#50 to RB#100, and the frequency domain resources occupied by BWP#2 are RB#80 to RB#160. It is also assumed that the frequency domain resources occupied by the UL subband are RB#60 to RB#75.

[0347] In one example, in response to the sub-band occupying all frequency domain resources being within the frequency domain resources occupied by the active BWP, the sub-band is determined to be in an active state; otherwise, the sub-band is determined to be in a deactivated state. Accordingly, Figure 7C When the UL BWP is activated as BWP#1, the terminal determines that the UL subband is in an active state. If the UL BWP is activated as BWP#2, the terminal's UL subband is in a deactivated state.

[0348] This patent does not limit the instructions for activating the UL BWP.

[0349] Example 4: As described in Example 3, the base station and terminal can determine whether the UL subband is active based on the number of first resource blocks (RBs). The first RB is an RB that simultaneously resides within the frequency domain resource range occupied by the active BWP and the frequency domain resource range occupied by the subband.

[0350] Specifically, the preset number T can be determined through protocol agreement or base station configuration. When the number of the first RB is greater than or equal to T, the terminal determines that the UL subband is in an active state; otherwise, it determines that the UL subband is in a deactivated state.

[0351] Example 5, the method described in Examples 1 to 4, can be directly applied to DL subband, and this example does not impose any limitations.

[0352] In the above embodiments, the terminal and the base station can determine whether to occupy the resources of the sub-band for information transmission based on the sub-band status, which optimizes resource allocation and helps to improve the transmission performance during full-duplex communication.
