Detailed Description

Reference will now be made in detail to exemplary embodiments, examples of which are illustrated in the accompanying drawings. When the following description refers to the accompanying drawings, the same numbers in different drawings refer to the same or similar elements, unless otherwise indicated. The implementations described in the following exemplary examples do not represent all implementations consistent with the invention. Rather, they are merely examples of apparatus and methods consistent with aspects of the invention as detailed in the accompanying claims.

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

It should be understood that although the terms first, second, third, etc. may be used in this disclosure to describe various information, these information should not be limited to these terms. These terms are only used to distinguish one type of information from another. For example, first information may also be referred to as second information, and similarly, second information may also be referred to as first information, without departing from the scope of the present disclosure. The word "if" as used herein may be interpreted as "at … …" or "at … …" or "responsive to a determination", depending on the context.

The third generation partnership project (3rd Generation Partnership Project,3GPP) consensus supports at least full duplex operation on semi-static flexible symbols (semi-static flexible symbol) and semi-static downlink symbols (DL symbols).

Here, flexible symbol refers to a symbol whose transmission direction is flexible (flexible), and downlink symbol refers to a symbol whose transmission direction is downlink.

Specifically, as an implementation manner, the following limitation is made on the behavior of the terminal in the full duplex communication:

the terminal can only execute uplink transmission in the frequency domain of UL subband;

the terminal can only perform downlink transmission in the frequency domain of DL subband.

Specifically, after the base station configures UL subband on DL symbol or flexible symbol for the terminal, the corresponding behavior of the terminal is as follows:

the terminal performs uplink transmission in the UL subband frequency domain;

the terminal performs downlink reception in the DL subband frequency domain outside the UL subband.

In the above manner, if there is no uplink transmission in the UL subband, the terminal still cannot receive downlink data in the frequency domain of the UL subband, thereby greatly limiting or even deteriorating the transmission performance of the terminal.

In order to solve the technical problems, the present disclosure provides the following method, device and storage medium for determining transmission behavior, which optimize resource allocation and are beneficial to improving transmission performance in full duplex communication.

The method for determining the transmission behavior provided by the present disclosure is described first from the terminal side. It should be noted that the terminals of the present disclosure may include, but are not limited to, a seamless bidirectional forwarding detection (Seamless Bidirectional Forwarding Detection, SBFD) aware (aware) terminal, and it is understood that the SBFD aware terminal is a terminal supporting full duplex communication.

An embodiment of the present disclosure provides a method for determining transmission behavior, referring to fig. 1, and fig. 1 is a flowchart illustrating a method for determining transmission behavior according to an embodiment, which may be performed by a terminal, and the method may include the steps of:

in step 101, the status of the sub-band is determined based on the information activating the partial bandwidth BWP.

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

The subband is illustratively an uplink subband that is located in a downlink time unit in the time domain, or the subband is a downlink subband that is located in an uplink time unit in the time domain.

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, for example.

The first time unit in the present disclosure may be in units of slots, symbols (symbols), duration (span), etc., which is not limited by the present disclosure. Wherein a span comprises a plurality of consecutive symbols.

In the embodiment of the present disclosure, the base station may configure a plurality of available BWP for the terminal, and the active BWP is a BWP in an active state among the plurality of available BWP. Wherein the plurality of available BWP comprises a plurality of available uplink BWP and/or a plurality of available downlink BWP, and the activated BWP may be an active uplink BWP in the plurality of available uplink BWP or an active downlink BWP in the plurality of available downlink BWP.

In the embodiments of the present disclosure, the information of the activated BWP may include, but is not limited to, an activated BWP identification, a frequency domain resource range of the activated BWP, etc., which is not limited in the present disclosure.

In the disclosed embodiments, the state of the sub-bands includes, but is not limited to, an active state, a deactivated state.

In one example, the sub-band is in an active state and the terminal may determine that configuration information of the sub-band is valid.

In another example, where the sub-band is in a deactivated state, the terminal may ignore configuration information of the sub-band.

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

In the embodiment of the present disclosure, the first transmission behavior refers to a transmission behavior of transmitting information by the terminal.

In the embodiment of the present 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 (RSs), and the channels include, but are not limited to, physical channels, logical channels, and the like.

In one example, the sub-band is in an active state, the terminal may perform a first transmission action according to a frequency domain resource range occupied by the sub-band, and the determined first transmission action may be included on the first resource, and the transmission action performed according to the second transmission direction. The first resource is located in the first time unit in the time domain and located in the frequency domain occupied by the sub-band in the frequency domain.

For example, the second transmission direction is uplink, and the terminal performs information transmission on the first resource. Where the information includes, but is not limited to, data, signals, channels, etc.

For another example, the second transmission direction is downlink, and the terminal performs information reception on the first resource. Where the information includes, but is not limited to, data, signals, channels, etc.

In addition, the terminal may also determine that the first transmission behavior is included on the second resource, the transmission behavior performed based on a time division multiplexing (Time Division Duplexing, TDD) structure configured or indicated by the base station. The second resource is located in the first time unit in the time domain and is located outside the frequency domain range occupied by the sub-band in the frequency domain.

For example, the terminal determines that the first transmission direction of the first time unit is downlink based on the TDD structure, and performs data reception on the second resource.

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

In another example, the sub-band is in a deactivated state, the terminal may ignore configuration information of the sub-band, and determine a first transmission behavior according to a TDD structure configured or indicated by the base station, the determined first transmission behavior may include, over the first time unit, transmission behavior performed based on a time division duplex TDD structure configured or indicated by the base station.

For example, the terminal determines that the first transmission direction of the first time unit is downlink based on the TDD structure, and performs data reception on the third resource. The third resource is located in the first time unit in the time domain, and may be located in the frequency domain resource range occupied by the sub-band in the frequency domain, or may be located outside the frequency domain resource range occupied by the sub-band.

For another example, the first transmission direction of the first time unit is determined to be flexible based on the TDD structure, and further, the base station further indicates, through the SFI or other TDD structure indication information, that the first transmission direction of the first time unit is downlink, and then the terminal performs data reception on the third resource. The third resource is located in the first time unit in the time domain, and may be located in the frequency domain resource range occupied by the sub-band in the frequency domain, or may be located outside the frequency domain resource range occupied by the sub-band.

The foregoing is merely exemplary, and a scheme for determining the first transmission behavior of the terminal based on the state of the sub-band shall belong to the protection scope of the present disclosure.

In the above embodiment, the terminal may determine the state of the sub-band based on the related information of the activated BWP, where the sub-band is located in a first time unit in the time domain, and the first transmission direction of the first time unit is opposite to or flexible to the second transmission direction of the sub-band, and further, the terminal may determine the first transmission behavior of the terminal based on the state of the sub-band. The resource allocation is optimized, and the transmission performance in full duplex communication is improved.

In some alternative embodiments, referring to fig. 2, fig. 2 is a flowchart illustrating a method for determining transmission behavior according to an embodiment, which may be performed by a terminal, the method may include the steps of:

in step 201, an associated BWP identification of the sub-band is determined.

In an embodiment of the present disclosure, the process of determining the associated BWP identification by the terminal may include: an associated BWP having an association relationship with the sub-band is first determined, and then an identification of the associated BWP is determined. In the disclosed embodiment, the associated BWP of the subband satisfies the following condition:

there is an overlap of the frequency domain resources occupied by the associated BWP associated with a subband with the frequency domain resources occupied by the subband. I.e. the frequency domain resources occupied by the associated BWP comprise at least one Resource Block (RB) belonging to the sub-band.

In the embodiment of the present disclosure, an uplink subband is associated with an uplink BWP, and a downlink subband is associated with a downlink BWP.

In one example, the associated BWP may be a BWP of which BWP index values among the plurality of BWP configured by the base station for the terminal satisfy a preset condition.

Wherein the preset condition may be maximum or minimum, which is not limited by the present disclosure.

I.e. the terminal determines the BWP with the smallest index value among the plurality of BWP as the associated BWP of the sub-band.

Or the terminal determines the BWP with the largest index value in the plurality of BWP as the associated BWP of the sub-band, and further determines the associated BWP identification.

In one example, the associated BWP may be an initial (initial) BWP.

Wherein the initial BWP may be a BWP configured by the base station for the terminal through the system message for the terminal to initially access the base station. The initial BWP may include an initial upstream BWP, an initial downstream BWP.

In one example, the associated BWP may be a first activated BWP.

Wherein the first activated BWP may be a BWP in an activated state, which is the first one of a plurality of available BWPs configured for the terminal by the base station.

For example, the associated BWP of the uplink sub-band may be the first activated uplink BWP (firstActiveUplinkBWP).

As another example, the associated BWP of the downlink sub-band may be the first activated downlink BWP (firstActiveDownlinkBWP).

In the disclosed embodiments, the terminal may determine the associated BWP in, but is not limited to, the following manner:

in one example, the terminal may determine the associated BWP based on a protocol convention.

For example, the protocol convention associated BWP is an initial BWP, and the terminal may determine the initial BWP as the associated BWP according to the protocol convention.

For another example, the protocol convention associates BWP with the first activated BWP, and the terminal determines the first activated BWP as the associated BWP according to the protocol convention.

For another example, if the protocol convention associated BWP is the BWP with the largest or smallest BWP index value among the plurality of BWP configured by the base station for the terminal, the terminal determines, as the associated BWP of the subband, the BWP with the largest or smallest BWP index value among the plurality of BWP (i.e., the plurality of available BWP configured by the base station for the terminal) according to the protocol convention.

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

Wherein the signaling includes, but is not limited to, any of the following: radio resource control (Radio Resource Control, RRC) signaling; a system message; media access control unit a media access control unit (Media Access Control Element, MAC CE).

The system message includes, but is not limited to, a system information block (System Information Block, SIB) message, which may be a SIBn message, where n is a positive integer, for example.

Illustratively, the indication information directly indicates the BWP associated with the sub-band.

Alternatively, the indication information may directly indicate the associated BWP identity. For example, the indication information indicates that the BWP index value is 2, the terminal determines that the associated BWP identification of the subband is 2. In the embodiment of the present disclosure, the base station may also associate BWP identifiers through implicit signaling indication, for example, the terminal determines in advance a correspondence between different indication information contents and different BWP identifiers, further determines, based on the correspondence, the BWP identifier corresponding to the indication information contents carried in the signaling sent by the base station, and determines the BWP identifier as the associated BWP identifier.

Alternatively, the indication information may indicate that the associated BWP is an initial BWP, or the indication information may also indicate BWP whose BWP index value satisfies a preset condition, or the indication information may indicate that the associated BWP is a first activated BWP. The present disclosure is not limited in this regard.

In another example, the terminal may determine whether the above signaling sent by the base station is received, and after receiving the signaling, determine the associated BWP based on the indication information carried in the signaling.

If the terminal does not receive the above-mentioned signaling, the terminal may determine an associated BWP based on the protocol convention.

In the embodiment of the present disclosure, after the terminal determines the associated BWP, the identity of the associated BWP may be determined, and optionally, an index value of the associated BWP may be used as the associated BWP identity.

In the embodiment of the disclosure, the terminal may determine the associated BWP identifier directly in addition to the associated BWP first and then the associated BWP identifier.

In one example, the indication information transmitted by the base station indicates an identification of the BWP first activated by the terminal, for example, a first actiondownlinkbwp-id, and the terminal may determine the BWP corresponding to the first actiondownbwp-id as the first activated downlink BWP based on the indication information, and may directly determine the first actiondownlinkbwp-id as the associated BWP identification based on the indication information. I.e. the terminal may directly determine the associated BWP identity on the basis of the associated BWP having the first activated BWP as a subband.

In another example, the base station configures an initial BWP identity for the terminal through the indication information, the terminal may determine a BWP corresponding to the initial BWP identity as an initial BWP based on the indication information, and may directly determine the initial BWP identity as an associated BWP identity based on the indication information. I.e. the terminal may directly determine the associated BWP identity on the basis of the associated BWP having the initial BWP as a subband.

The foregoing is merely exemplary, and it is within the scope of the present disclosure that a terminal may determine the associated BWP and thus the associated BWP identifier in other manners, or directly determine the associated BWP identifier.

In step 202, in response to the active BWP identity being the same as the associated BWP identity, it is determined that the sub-band is in an active state.

In the embodiment of the present disclosure, when the active BWP identifier is the same as the associated BWP identifier, the terminal determines that the subband is in an active state.

In step 203, in response to the active BWP identity being different from the associated BWP identity, it is determined that the sub-band is in a deactivated state.

In an embodiment of the present disclosure, the terminal determines that the sub-band is in the deactivated state when the active BWP identification is different from the associated BWP identification.

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

The implementation of step 204 is similar to that of step 102 described above, and will not be described again.

In the above embodiment, the terminal may determine the state of the sub-band based on whether the active BWP identifier is the same as the associated BWP identifier, where the sub-band is located in a first time unit in the time domain, and a first transmission direction of the first time unit is opposite to or flexible to a second transmission direction of the sub-band, and further, the terminal may determine the first transmission behavior of the terminal based on the state of the sub-band. The resource allocation is optimized, and the transmission performance in full duplex communication is improved.

In some alternative embodiments, referring to fig. 3, fig. 3 is a flowchart illustrating a method for determining transmission behavior according to an embodiment, which may be performed by a terminal, the method may include the steps of:

In step 301, the state of a subband is determined based on the frequency domain resources occupied by the activated BWP and the frequency domain resources occupied by the subband.

In one example, the terminal determines that the sub-band is in an active state if all of the frequency domain resources occupied by the sub-band are within the frequency domain resources occupied by the active BWP. And if part of the frequency domain resources occupied by the sub-band are outside the frequency domain resources occupied by the activated BWP, determining that the sub-band is in a deactivated state.

In another example, the terminal determines the number of first resource blocks RBs, wherein the first RBs are RBs that are simultaneously within a frequency domain resource range occupied by the active BWP and within a frequency domain resource range occupied by the sub-band, i.e. the first RBs are RBs common to the sub-band and the active BWP.

If the number of the first RBs is greater than or equal to the preset number, the terminal determines that the sub-band is in an activated state. And if the number of the first RBs is smaller than the preset number, determining that the sub-band is in a deactivated state.

Wherein the preset number may be agreed by a protocol or configured by a base station, which is not limited by the present disclosure.

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

The implementation of step 302 is similar to that of step 102 described above, and will not be described again here.

In the above embodiment, the terminal may determine the state of the subband based on the frequency domain resource occupied by the activated BWP and the frequency domain resource occupied by the subband, where the subband is located in a first time unit in the time domain, and the first transmission direction of the first time unit is opposite to or flexible to the second transmission direction of the subband, and further, the terminal may determine the first transmission behavior of the terminal based on the state of the subband. The resource allocation is optimized, and the transmission performance in full duplex communication is improved.

The method for determining the transmission behavior provided by the present disclosure is further described below from the base station side.

An embodiment of the present disclosure provides a method for determining transmission behavior, referring to fig. 4, and fig. 4 is a flowchart illustrating a method for determining transmission behavior according to an embodiment, which may be performed by a base station, and may include the steps of:

in step 401, the state of the sub-band configured for the terminal is determined based on the information activating the partial bandwidth BWP.

In one example, the sub-band is in an active state and the base station may determine that configuration information for configuring the sub-band for the terminal is in effect.

In another example, the sub-band is in a deactivated state and the base station may determine that the terminal ignores configuration information of the sub-band.

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

In the embodiment of the present disclosure, the second transmission behavior refers to a transmission behavior of the base station transmitting information. The second transmission behavior corresponds to the first transmission behavior.

For example, the first transmission behavior performed by the terminal includes information reception, and the second transmission behavior performed by the base station includes information transmission.

For another example, the first transmission behavior performed by the terminal includes information transmission, and the second transmission behavior performed by the base station includes information reception.

In the 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, RSs, and the channels include, but are not limited to, physical channels, logical channels, and the like.

In one example, the sub-band is in an active state, the base station may perform a second transmission action according to a frequency domain resource range occupied by the sub-band, and the determined second transmission action may be included on the first resource, and the transmission action performed according to the second transmission direction may be performed. The first resource is located in the first time unit in the time domain and located in the frequency domain occupied by the sub-band in the frequency domain.

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

For another example, the second transmission direction is downlink, and the base station performs information transmission on the first resource. Where the information includes, but is not limited to, data, signals, channels, etc.

In addition, the base station may also determine that a second transmission behavior is included on the second resource based on a transmission behavior performed for the TDD structure configured or indicated by the terminal. The second resource is located in the first time unit in the time domain and is located outside the frequency domain range occupied by the sub-band in the frequency domain.

For example, the base station determines that the first transmission direction of the first time unit is downlink based on the TDD structure, and performs data transmission on the second resource.

For another example, the base station may further indicate, by using the SFI or other TDD structure indication information, that the first transmission direction of the first time unit is downlink, and then perform data transmission on the second resource.

In another example, the sub-band is in a deactivated state, the base station may determine that the terminal ignores configuration information of the sub-band, and determine a second transmission behavior according to a TDD structure configured or indicated for the terminal, the determined second transmission behavior may be included on the first time unit based on transmission behavior performed for the time division multiplexed TDD structure configured or indicated for the terminal.

For example, the base station determines that the first transmission direction of the first time unit is downlink based on the TDD structure, and performs data transmission on the third resource. The third resource is located in the first time unit in the time domain, and may be located in the frequency domain resource range occupied by the sub-band in the frequency domain, or may be located outside the frequency domain resource range occupied by the sub-band.

For another example, the base station determines that the first transmission direction of the first time unit is flexible based on the TDD structure, and further indicates 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 performs data transmission on the third resource. The third resource is located in the first time unit in the time domain, and may be located in the frequency domain resource range occupied by the sub-band in the frequency domain, or may be located outside the frequency domain resource range occupied by the sub-band.

The above is merely exemplary, and a scheme of determining the second transmission behavior of the base station based on the state of the sub-band shall fall within the protection scope of the present disclosure.

In the above embodiment, the base station may determine the state of the subband based on the information related to the activation of BWP, where the subband is located in a first time unit in the time domain, and the first transmission direction of the first time unit is opposite to or flexible to the second transmission direction of the subband, and further, the base station may determine the second transmission behavior of itself based on the state of the subband. The resource allocation is optimized, and the transmission performance in full duplex communication is improved.

In some alternative embodiments, referring to fig. 5, fig. 5 is a flowchart illustrating a method for determining transmission behavior, which may be performed by a base station, according to an embodiment, the method may include the steps of:

in step 501, an associated BWP identification of the subband is determined.

In an embodiment of the present disclosure, the process of the base station determining the associated BWP identity may include: an associated BWP having an association relationship with the sub-band is first determined, and then an identification of the associated BWP is determined.

In the disclosed embodiment, the associated BWP of the subband satisfies the following condition:

there is an overlap of the frequency domain resources occupied by the associated BWP associated with a subband with the frequency domain resources occupied by the subband. I.e. the frequency domain resources occupied by the associated BWP comprise at least one RB belonging to the subband.

In one example, the associated BWP may be a BWP of which BWP index value satisfies a preset condition among the plurality of bwtps configured for the terminal.

I.e. the base station determines the BWP with the smallest index value of the plurality of BWP as the associated BWP of the subband.

Or the base station determines the BWP with the largest index value among the BWP as the associated BWP of the sub-band, and further determines the associated BWP identification.

In one example, the associated BWP may be initial BWP.

In one example, the associated BWP may be a first activated BWP.

In the disclosed embodiments, the base station may determine the associated BWP in, but is not limited to, the following manner:

in one example, the base station may determine the associated BWP based on a protocol convention.

For example, the protocol convention associated BWP is an initial BWP, and the base station may determine the initial BWP as the associated BWP according to the protocol convention.

For another example, the protocol convention associates BWP with the first activated BWP, and the base station determines the first activated BWP as the associated BWP according to the protocol convention.

For another example, if the associated BWP is the BWP with the largest or smallest BWP index value among the BWP plurality configured by the base station for the terminal, the base station determines the BWP with the largest or smallest BWP index value among the BWP plurality (i.e., the BWP available to the base station for the terminal) as the associated BWP of the subband according to the protocol convention.

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

Wherein the signaling includes, but is not limited to, any of the following: RRC signaling; a system message; MAC CE).

The system message includes, but is not limited to, a SIB message, which may be a SIBn message, where n is a positive integer, for example.

Alternatively, the indication information may directly indicate the associated BWP identity. For example, the indication information indicates that the BWP index value is 2, and the base station indicates that the associated BWP identification of the subband is 2.

In the embodiment of the present disclosure, the base station may also implicitly indicate the associated BWP through the signaling, for example, the base station determines the indication information content corresponding to the associated BWP according to the correspondence between different indication information contents and different BWP, further based on the correspondence, and carries the corresponding indication information content in the signaling, and further sends the signaling to the terminal, so that the terminal determines the associated BWP based on the indication information content and the correspondence.

In another example, the base station may determine that the terminal determines the associated BWP according to the indication information carried in the signaling after transmitting the signaling, and in addition, the base station determines that the terminal determines the associated BWP based on the protocol convention without transmitting the signaling to the terminal.

In the embodiment of the present disclosure, after the base station determines the associated BWP, the identity of the associated BWP may be determined, and optionally, an index value of the associated BWP may be used as the associated BWP identity.

In the embodiment of the disclosure, the base station may determine the associated BWP identifier directly in addition to the associated BWP first and then the associated BWP identifier.

In one example, the indication information sent by the base station indicates an identification of the BWP activated by the terminal for example, a first actiondownlinkbwp-id, which is equivalent to that the base station informs the terminal of the first activated BWP identification and the associated BWP identification simultaneously through the indication information, and the terminal determines the BWP corresponding to the first actiondownlinkbwp-id as the first activated BWP, and may directly determine the first actiondownlinkbwp-id as the associated BWP identification based on the indication information.

In another example, the base station indicates the initial BWP identity through the indication information, and the terminal may determine the BWP corresponding to the initial BWP identity as the initial BWP based on the indication information, and may directly determine the initial BWP identity as the associated BWP identity based on the indication information.

The foregoing is merely exemplary, and other schemes for determining the associated BWP identity by the base station are within the scope of the present disclosure.

In step 502, in response to the active BWP identity being the same as the associated BWP identity, it is determined that the subband is in an active state.

In an embodiment of the present disclosure, the base station determines that the subband is in an active state when the active BWP identity is the same as the associated BWP identity.

In step 503, in response to the active BWP identity being different from the associated BWP identity, it is determined that the sub-band is in a deactivated state.

In an embodiment of the present disclosure, the base station determines that the subband is in a deactivated state when the active BWP identity is different from the associated BWP identity.

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

The implementation of step 504 is similar to step 402 described above and will not be described in detail here.

In the above embodiment, the base station may determine the state of the sub-band based on whether the active BWP identifier is the same as the associated BWP identifier, where the sub-band is located in a first time unit in the time domain, and a first transmission direction of the first time unit is opposite to or flexible to a second transmission direction of the sub-band, and further, the base station may determine the second transmission behavior of the base station based on the state of the sub-band. The resource allocation is optimized, and the transmission performance in full duplex communication is improved.

In some alternative embodiments, referring to fig. 6, fig. 6 is a flowchart illustrating a method for determining transmission behavior, which may be performed by a base station, according to an embodiment, the method may include the steps of:

in step 601, the state of a subband is determined based on the frequency domain resources occupied by the activated BWP and the frequency domain resources occupied by the subband.

The first time unit in the present disclosure may be in units of slot, symbol, span and the like, which is not limited by the present disclosure. Wherein a span comprises a plurality of consecutive symbols.

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

In another example, the base station determines the number of first resource blocks RBs, wherein the first RBs are RBs that are simultaneously within the frequency domain resource range occupied by the activated BWP and within the frequency domain resource range occupied by the sub-band, i.e. the first RBs are RBs common to the sub-band and the activated BWP.

If the number of the first RBs is greater than or equal to the preset number, the base station determines that the sub-band is in an activated state. If the number of the first RBs is smaller than the preset number, the base station determines that the sub-band is in a deactivated state.

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

The implementation of step 602 is similar to that of step 402 described above, and will not be described in detail herein.

In the above embodiment, the base station may determine the state of the subband based on the frequency domain resource occupied by the activated BWP and the frequency domain resource occupied by the subband, where the subband is located in a first time unit in the time domain, and the first transmission direction of the first time unit is opposite to or flexible to the second transmission direction of the subband, and further, the base station may determine the second transmission behavior of the base station based on the state of the subband. The resource allocation is optimized, and the transmission performance in full duplex communication is improved.

In order to facilitate an understanding of the above-described aspects, the present disclosure provides the following embodiments.

In embodiment 1, the terminal is assumed to be a terminal with full duplex capability, that is, the terminal may perform uplink transmission in UL subband on DL symbol or flexible symbol, or perform downlink reception in DL subband on UL symbol or flexible symbol.

It is assumed that the base station side performs full duplex operation on the semi-stable fexible symbol and/or the semi-stable symbol of the TDD band, that is, performs scheduling of downlink data and uplink data at the same time. In this embodiment, it is assumed that the semi-static flexible symbol and semi-static DL symbol are determined by a common TDD configuration (TDD-UL-DL-configuration communication) transmitted from a base station or by a TDD-UL-DL-configuration communication and a terminal-specific TDD configuration (TDD-UL-DL-configuration defined). The base station indicates UL subband on the semi-static flexible symbol and semi-static DL symbol by the terminal as follows. Of course, the base station may indicate or configure UL subband in other manners, and may also indicate or configure DL subband, which is not limited in this embodiment:

And the base station configures UL subband for the terminal.

In the UL subband, the terminal can only perform uplink transmission;

in the DL subband, the terminal can only perform downlink reception.

The base station performs scheduling, configuration or indication of reference signals of the data channels in the UL subband or the DL subband.

In this embodiment, it is assumed that the slot structure configured by the base station through TDD UL-DL configuration is DDDFU, and as shown in fig. 7A, that is, in the TDD configuration period, slot #0, slot #1, and slot #2 are DL slots, slot #3 is a flexible slot, and slot #4 is a UL slot. Of course, the embodiment method can be directly applied to other TDD UL DL slot structures.

In this embodiment, it is assumed that the base station configures UL subbands on slot #1, slot #2, and slot #3 for the terminal, as shown in fig. 7B. For simplicity, the present embodiment does not consider a guard period (guard period) or a switching time between DL symbol and UL subband. Of course, the base station may alternatively be configured in other UL subbands without affecting the implementation of the protection scheme of this patent.

In this embodiment, it is assumed that the frequency domain resources of 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 UL transmission is reduced in UL subband, a base station may deactivate (disable) the UL subband according to a certain rule, thereby releasing resources occupied by UL subband and making it available for DL transmission, so as to enhance DL transmission performance.

In this embodiment, the base station and the terminal determine, by using a protocol agreed manner, an associated BWP identifier of the subband, and determine, by whether the current active UL BWP identifier is the same as the associated BWP identifier of the subband, whether the subband is in an active state. For the state of subband, the following is defined:

UL subband is in active state: the terminal performs uplink transmission in the UL subband or performs downlink reception outside the UL subband according to the UL subband configured or indicated by the base station. Further, the present embodiment assumes that the terminal cannot receive downlink data within the UL subband range.

UL subband is in deactivated state: the terminal ignores the UL subband configured or indicated by the base station, and determines a first transmission behavior of the terminal according to the TDD structure configured or indicated by the base station.

For example, if UL subband in deactivated state is located on DL symbol, then the SBFD aware terminal recognizes that no UL subband is present on this DL symbol.

For another example, if the UL subband in the deactivated state is located on the flexible symbol, then the SBFD aware terminal recognizes that no UL subband is present on this flexible symbol.

In this embodiment, the associated BWP identifier of the UL subband may be specifically determined by the following method, which is not limited in this patent:

The associated BWP is a BWP having the smallest index value among a plurality of available BWPs configured for the terminal by the base station;

alternatively, the associated BWP is a BWP having the largest index value among a plurality of available BWPs configured for the terminal by the base station;

alternatively, the associated BWP is the BWP of the first ActiveUpLinkBWP-Id;

alternatively, the associated BWP is initial UL BWP.

Specifically, if the active UL BWP identity is the same as the associated BWP identity, the UL subband is in an active state; the UL subband is in a deactivated state if the active UL BWP identity is different from the associated BWP identity.

It should be noted that there is an overlap of the frequency domain resources occupied by the associated BWP with the frequency domain resources occupied by the subbands, i.e. the associated BWP comprises at least one RB belonging to UL subband.

In embodiment 2, the terminal is assumed to be a terminal with full duplex capability, that is, the terminal may perform uplink transmission in UL subband on DL symbol or flexible symbol, or perform downlink reception in DL subband on UL symbol or flexible symbol.

And the base station configures UL subband for the terminal.

In the UL subband, the terminal can only perform uplink transmission;

in the DL subband, the terminal can only perform downlink reception.

In this embodiment, the base station indicates, by means of signaling indication, an associated BWP identifier of UL subband for the terminal, and determines whether the subband is in an active state by activating whether the UL BWP identifier is the same as the associated BWP identifier of the subband. For the state of subband, the following is defined:

The foregoing signaling may be RRC signaling, or a system message, such as SIB1, or MAC CE, and the disclosure may carry, through the foregoing signaling, indication information, where the indication information is used to indicate an associated BWP identifier, and the embodiment is not limited in any way.

Further, when the base station does not configure or indicate the associated BWP identifier for the terminal, the terminal may determine the associated BWP identifier in a protocol agreed manner, and the specific method may refer to embodiment 1, which is not described herein.

Embodiment 3 assumes that the terminal is a terminal with full duplex capability, that is, the terminal may perform uplink transmission in UL subband on DL symbol or flexible symbol, or perform downlink reception in DL subband on UL symbol or flexible symbol.

And the base station configures UL subband for the terminal.

In the UL subband, the terminal can only perform uplink transmission;

in the DL subband, the terminal can only perform downlink reception.

In this embodiment, the base station and the terminal determine whether the subband is in an activated state by activating the frequency domain resources occupied by the BWP and the frequency domain resources occupied by the subband. For the state of subband, the following is defined:

In this embodiment, it is assumed that the base station configures two BWP for the terminal, and as shown in fig. 7C, for convenience 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. The frequency domain resources occupied by UL subband are assumed to be rb#60 to rb#75.

In one example, in response to the frequency domain resources occupied by the sub-band being all 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, and accordingly, in fig. 7C, when the active UL BWP is bwp#1, the terminal determines that UL subband is in an active state, and when the active UL BWP is bwp#2, the terminal UL subband is in a deactivated state.

The present patent does not make any limitation on the indication of activating UL BWP.

Embodiment 4 the method of embodiment 3 wherein the base station and the terminal can determine whether UL subband is in active state according to the number of first resource blocks RBs. Wherein the first RB is an RB that is located in a frequency domain resource range occupied by the activated BWP and a frequency domain resource range occupied by the subband at the same time.

Specifically, the preset number T may be determined by means of a protocol convention or a base station configuration. And when the number of the first RBs is greater than or equal to T, the terminal determines that the UL sub-band is in an activated state, otherwise, determines that the UL sub-band is in a deactivated state.

Example 5, the methods described in examples 1 to 4, can be directly applied to DL subband, and this example is not limited in any way.

In the above embodiment, the terminal and the base station may determine whether to occupy the resources of the sub-band for information transmission based on the state of the sub-band, so as to optimize resource allocation and facilitate improvement of transmission performance during full duplex communication.
