[0002] The present disclosure is based on and claims priority from Chinese Patent Application No. 2024106506059, filed on May 23, 2024, the entire contents of which are incorporated herein by reference in its entirety. TECHNICAL FIELD

[0003] The present disclosure relates to the technical field of wireless communication, and particularly relates to an information processing method, device, equipment, storage medium and computer program product. BACKGROUND

[0004] At present, a base station uses a time division multiplexing (TDM) manner on a time division duplexing (TDD) carrier to perform uplink and downlink multiplexing transmission. In a traditional TDD system, the terminal judges whether a physical random access channel occasion (RO) configured by the network is a valid RO according to an existing manner, and sends a random access preamble on the valid RO. However, the existing manner of judging the validity of the RO is relatively fixed, and cannot judge the validity of the RO according to the network configuration. Thus, when a TDD carrier is configured to perform subband non-overlapping full duplex (SBFD) operation, the existing manner of judging the validity of the RO may not be applicable to terminals supporting specific functions, such as terminals supporting the SBFD function.

[0136] Before introducing the technical solutions of the embodiments of the present disclosure, the related art is introduced.

[0137] In the related art, the base station uses the time division multiplexing (TDM) mode to perform uplink and downlink multiplexing transmission on one time division duplexing (TDD) carrier. Since the uplink duty cycle is limited, the uplink coverage performance of the user equipment (UE) and the uplink and downlink delay are limited by the TDD uplink and downlink configuration.

[0138] The currently discussed subband non-overlapping full duplex (SBFD) is to configure a part of time slots or symbols as SBFD slots or symbols, i.e., a part of frequency resources of a BWP (uplink BWP or downlink BWP) is used as an SBFD uplink subband (SBFD-UL subband), and another part of frequency resources is used as an SBFD downlink subband (SBFD-DL subband). When the base station transmits on one SBFD symbol, the base station can perform uplink reception on the SBFD-UL subband while performing downlink transmission on the SBFD-DL subband, so as to realize simultaneous uplink and downlink transmission of the base station.

[0139] FIG. 1 is a schematic diagram of a typical SBFD in the related art. As shown in FIG. 1, 100 MHz corresponds to an uplink BWP or a downlink BWP, 20 MHz corresponds to an SBFD uplink subband (SBFD-UL subband), and 40 MHz corresponds to an SBFD downlink subband (SBFD-DL subband).

[0140] Table 1 is a schematic diagram of an SIB1 message in the related art. As shown in Table 1, in a conventional TDD system, the network configures random access resources for the UE, for example, the network broadcasts random access configuration information in the SIB1 through the following signaling.

[0141] Table 1

[0142] Currently, in a conventional TDD system, when the physical random access channel occasion (RO, PRACH occasion) resource configured by the network satisfies the following conditions, the RO is considered to be a valid RO (valid RO):

[0143] In the case where tdd-UL-DL-ConfigurationCommon is not provided to the UE, the RO in the PRACH slot is considered to be valid if it does not precede a synchronization signal (SS) / physical broadcast channel (PBCH) block in the PRACH slot and starts at least Ngap symbols after the last SS / PBCH block transmission symbol; where Ngap is an integer greater than or equal to 0.

[0144] Or,

[0145] If the UE is provided tdd-UL-DL-ConfigurationCommon, an RO in a PRACH slot is considered valid if the following is met: it is within UL symbols; or, it is not preceded by an SS / PBCH block in the PRACH slot and starts at least Ngap symbols after the last downlink symbol, and starts at least Ngap symbols after the last SS / PBCH block transmission symbol; where Ngap is an integer greater than or equal to 0.

[0146] In the related art, in the conventional TDD system, the terminal judges whether the RO configured by the network is a valid RO in the existing manner, and transmits the random access preamble on the valid RO. However, the existing manner of judging the validity of the RO is relatively fixed, and cannot judge the validity of the RO according to the network configuration, so when a TDD carrier is configured to perform SBFD operation, the existing manner of judging the validity of the RO may not be applicable to terminals supporting specific functions, such as terminals supporting SBFD functions.

[0147] Based on this, in the embodiments of the present disclosure, in the case where the first indication information and / or the second indication information are defined, the validity judgment rule is determined based on the configuration of the first indication information and / or the second indication information; the first indication information and the second indication information are different; the validity of the first RO and / or the second RO is judged based on the validity judgment rule; wherein the first RO is an RO determined by the terminal according to a first random access configuration parameter set; the second RO is an RO determined by the terminal according to a second random access configuration parameter set; the first random access configuration parameter set and the second random access configuration parameter set are different.

[0148] Before further detailing the embodiments of the present disclosure, the terms and terms involved in the embodiments of the present disclosure are explained, and the terms and terms involved in the embodiments of the present disclosure are applicable to the following explanations.

[0149] 1) Sub-band non-overlapping full duplex (SBFD), abbreviated as sub-band full duplex, is to configure a part of time slots or symbols as SBFD slots or symbols, that is, to use a part of frequency resources of a BWP (uplink BWP or downlink BWP) as an SBFD uplink sub-band (SBFD-UL subband), and another part of frequency resources as an SBFD downlink sub-band (SBFD-DL subband).

[0150] 2) SBFD subband: consists of a set of contiguous resource blocks (RBs) for the same transmission direction (including 1 or more RBs), SBFD subband with transmission direction as uplink becomes SBFD-UL subband, and SBFD subband with transmission direction as downlink becomes SBFD-DL subband.

[0151] 3) Guard subband: defined as one or more RBs between adjacent SBFD-UL subband and SBFD-DL subband, neither used for uplink transmission nor for downlink transmission.

[0152] 4) SBFD symbol / slot: defined as a symbol / slot configured with SBFD subband(s), or defined as a symbol / slot configured with SBFD subband(s) and that symbol / slot will be used for SBFD operation, or defined as a symbol / slot used for SBFD operation.

[0153] 5) Non-SBFD symbol / slot: defined as a symbol / slot without SBFD subband(s) configured, or defined as including a symbol / slot without SBFD subband(s) configured and a symbol / slot configured with SBFD subband(s) but not used for SBFD operation, or defined as a symbol / slot not used for SBFD operation.

[0154] 6) UL usable PRBs: frequency domain resources in SBFD-UL subband in a SBFD symbol of a downlink symbol or a flexible symbol that overlap with an uplink (UL) BWP.

[0155] 7) DL usable PRBs: frequency domain resources in SBFD-DL subband in a SBFD symbol of a downlink symbol or a flexible symbol that overlap with a downlink (DL) BWP.

[0156] Referring to FIG. 2, FIG. 2 is a flowchart illustrating an implementation of an information processing method according to an embodiment of the present disclosure, which is applied to a terminal, which can be an SBFD aware UE. As shown in FIG. 2, the method comprises steps 201 to 202.

[0157] In step 201, when the first indication information and / or the second indication information is defined, a validity determination rule is determined based on a configuration of the first indication information and / or the second indication information. The first indication information and the second indication information are different.

[0158] As an example, the first indication information being defined can mean that the terminal and the network device can understand the specific meaning of the first indication information, or that the terminal and the network device have previously agreed on an information parameter with a specific meaning.

[0159] As an example, the second indication information being defined can mean that the terminal and the network device can understand the specific meaning of the second indication information, or that the terminal and the network device have previously agreed on an information parameter with a specific meaning.

[0160] In some embodiments, the first indication information is a newly defined information element (IE) in a rach-ConfigCommon message included in a system information block 1 (SIB1) message; and the second indication information is a newly defined rach-ConfigCommonSBFD for SBFD in the SIB1 message.

[0161] As an example, the newly defined IE can be specifically rachSBFD ENUMERATED{true}OPTIONAL.

[0162] As an example, rach-ConfigCommonSBFD can also be described as SetupRelease{RACH-ConfigCommon}.

[0163] In existing conventional TDD systems, a terminal determines whether a RO configured by a network is a valid RO in an existing manner, and transmits a random access preamble on the valid RO. However, the existing manner of determining the validity of a RO is relatively fixed, that is, a valid RO is in an uplink (UL) symbol. Thus, when a TDD carrier is configured to perform SBFD operation, an SBFD aware terminal can only transmit a random access preamble on the UL symbol, which can cause collision of random access resources, thereby increasing the latency of random access. That is, the existing manner of determining the validity of a RO can not be applicable to an SBFD aware terminal.

[0164] Therefore, in the embodiments of the present disclosure, when the first indication information and / or the second indication information is defined, the terminal determines the validity judgment rule based on the configuration of the network to the first indication information and / or the second indication information. Thus, when one TDD carrier is configured to perform SBFD operation, for terminals supporting specific functions such as SBFD function, the appropriate validity judgment rule can be determined in combination with the configuration of the network to the first indication information and / or the second indication information, which provides a more flexible validity judgment mode, thereby realizing wide application range, and also can reduce the occurrence of problems such as random access resource collision and random access delay increase.

[0165] Step 202: determining the validity of the first RO and / or the second RO based on the validity judgment rule; wherein the first RO is an RO determined by the terminal according to a first random access configuration parameter set; the second RO is an RO determined by the terminal according to a second random access configuration parameter set; the first random access configuration parameter set and the second random access configuration parameter set are different.

[0166] As an example, the first random access configuration parameter set and the first indication information can be sent separately or simultaneously by the network device to the terminal; the second random access configuration parameter set and the second indication information can be sent separately or simultaneously by the network device to the terminal.

[0167] In actual application, before determining the validity judgment rule, the network device can send a first message such as SIB1 message to the terminal, so that when the first indication information and / or the second indication information is defined, the terminal can determine whether the network device configures the first indication information according to whether the first indication information is included in the first message, and / or determine whether the network device configures the second indication information according to whether the second indication information is included in the first message.

[0168] Based on this, in some embodiments, the method further includes:

[0169] receiving a first message sent by the network device;

[0170] When the first indication information and / or the second indication information is defined, determining the configuration of the first indication information and / or the second indication information according to the first message.

[0171] As an example, the first message can be specifically SIB1 message.

[0172] Specifically, the following cases can be included:

[0173] In a case where the first indication information is defined and the second indication information is not defined, a configuration of the first indication information is determined according to whether the first message contains the first indication information;

[0174] Alternatively,

[0175] In a case where the first indication information is not defined and the second indication information is defined, a configuration of the second indication information is determined according to whether the first message contains the second indication information;

[0176] Alternatively,

[0177] In a case where the first indication information and the second indication information are both defined, configurations of the first indication information and the second indication information are determined according to whether the first message contains the first indication information and whether the first message contains the second indication information.

[0178] In some embodiments, the determining, in a case where the first indication information and / or the second indication information is defined, the configuration of the first indication information and / or the second indication information according to the first message comprises:

[0179] In a case where the first indication information is defined and the second indication information is not defined, if the first message does not contain the first indication information, it is determined that the network device does not configure the first indication information;

[0180] Alternatively,

[0181] In a case where the first indication information is defined and the second indication information is not defined, if the first message contains the first indication information, it is determined that the network device configures the first indication information;

[0182] Alternatively,

[0183] In a case where the first indication information is not defined and the second indication information is defined, if the first message does not contain the second indication information, it is determined that the network device does not configure the second indication information;

[0184] Alternatively,

[0185] In a case where the first indication information is not defined and the second indication information is defined, if the first message contains the second indication information, it is determined that the network device configures the second indication information;

[0186] Alternatively,

[0187] In a case where the first indication information and the second indication information are both defined, if the first message does not contain the first indication information and does not contain the second indication information, it is determined that the network device does not configure the first indication information and does not configure the second indication information.

[0188] Alternatively,

[0189] In a case where the first indication information and the second indication information are both defined, if the first message contains the first indication information and does not contain the second indication information, it is determined that the network device configures the first indication information and does not configure the second indication information.

[0190] Alternatively,

[0191] In a case where the first indication information and the second indication information are both defined, if the first message does not contain the first indication information and contains the second indication information, it is determined that the network device does not configure the first indication information and configures the second indication information.

[0192] Alternatively,

[0193] In a case where the first indication information and the second indication information are both defined, if the first message contains the first indication information and contains the second indication information, it is determined that the network device configures the first indication information and configures the second indication information.

[0194] The process of how to determine the validity determination rule will be described in detail below.

[0195] In a case where the first indication information is defined and the second indication information is not defined, the validity determination rule is determined based on the configuration of the first indication information.

[0196] Based on this, in some embodiments, in a case where the first indication information and / or the second indication information is defined, the validity determination rule is determined based on the configuration of the first indication information and / or the second indication information, including:

[0197] In a case where the first indication information is defined and the second indication information is not defined, the validity determination rule is determined based on the configuration of the first indication information.

[0198] In some embodiments, the validity determination rule is determined based on the configuration of the first indication information, including:

[0199] If the network device is not configured with the first indication information, it is determined that the validity judgment rule is a first validity judgment rule; the first validity judgment rule is used to judge the validity of the first RO.

[0200] Alternatively,

[0201] If the network device is configured with the first indication information, it is determined that the validity judgment rule is a second validity judgment rule; the second validity judgment rule is used to judge the validity of the first RO.

[0202] Alternatively,

[0203] If the network device is configured with the first indication information, and the state of the first indication information is an invalid state, it is determined that the validity judgment rule is a first validity judgment rule; the first validity judgment rule is used to judge the validity of the first RO.

[0204] Alternatively,

[0205] If the network device is configured with the first indication information, and the state of the first indication information is an effective state, it is determined that the validity judgment rule is a second validity judgment rule; the second validity judgment rule is used to judge the validity of the first RO.

[0206] Among them, the first validity judgment rule and the second validity judgment rule are different.

[0207] As an example, the first indication information has at least two states, namely an invalid state and an effective state.

[0208] Specifically, the state of the first indication information is an invalid state, which can be understood as the value of the parameter corresponding to the first indication information being disable or false; the state of the first indication information is an effective state, which can be understood as the value of the parameter corresponding to the first indication information being enable or true.

[0209] In some embodiments, the first validity judgment rule comprises:

[0210] In the case where the terminal is not provided with tdd-UL-DL-ConfigurationCommon by the network, the valid RO is not before the SS / PBCH block in the PRACH slot, and the valid RO starts at least Ngap symbols after the last SS / PBCH block transmission symbol; wherein Ngap is an integer greater than or equal to 0;

[0211] Alternatively,

[0212] In a case that the terminal is provided with the tdd-UL-DL-ConfigurationCommon by the network, the valid RO is within the UL symbol; or, the valid RO is not before the SS / PBCH block in the PRACH slot, and the valid RO starts at least Ngap symbols after the last downlink symbol, and the valid RO starts at least Ngap symbols after the last SS / PBCH block transmission symbol; wherein Ngap is an integer greater than or equal to 0.

[0213] For example, in a case that the first indication information is defined and the second indication information is not defined, if the network device does not configure the first indication information, or, if the network device configures the first indication information and the state of the first indication information is an invalid state, the first validity judgment rule is adopted for the first RO.

[0214] In some embodiments, the second validity judgment rule comprises:

[0215] The valid RO is located in the uplink available PRBs on the SBFD symbol indicated by the first instruction as a downlink symbol by the network device; the uplink available PRBs are frequency domain resources of the SBFD uplink sub-band in the SBFD symbol and the uplink BWP.

[0216] That is, the second validity rule at least allows the valid RO to be located in the uplink available physical resource block (UL usable PRB) on the SBFD symbol indicated by the first instruction (tdd-UL-DL-ConfigurationCommon) as a downlink symbol (downlink symbol); the uplink available PRB is the frequency domain resource of the SBFD uplink sub-band in the SBFD symbol and the uplink BWP.

[0217] For example, in a case that the first indication information is defined and the second indication information is not defined, if the network device configures the first indication information, or, if the network device configures the first indication information and the state of the first indication information is an effective state, the second validity judgment rule is adopted for the first RO.

[0218] Table 2 is a schematic of the first message, i.e., the SIB1 message, of the embodiment of the present disclosure. As shown in Table 2, the first indication information, i.e., the parameter rachSBFD, is defined (may also be described as introduced) in the common random access configuration (rach-ConfigCommon) in the first message (SIB1 message), and the second indication information is not defined. The first RO is determined according to the first random access configuration parameter set associated with the rach-ConfigCommon in the SIB1 message. The validity judgment rule for determining the first RO can include the following:

[0219] If the SIB1 message sent by the network device does not indicate the parameter rachSBFD, that is, the SIB1 message does not contain the parameter rachSBFD, the terminal such as a UE judges whether the first RO is a valid RO based on the first validity judgment rule; or if the SIB1 message sent by the network device indicates the parameter rachSBFD, that is, the SIB1 message contains the parameter rachSBFD, the terminal judges whether the first RO is a valid RO based on the second validity judgment rule.

[0220] Or, if the SIB1 message sent by the network device indicates the parameter rachSBFD, and the value of the parameter is disable or false, the terminal judges whether the first RO is a valid RO based on the first validity judgment rule; or if the SIB1 message sent by the network device indicates the parameter rachSBFD, and the value of the parameter is enable or true, the terminal judges whether the first RO is a valid RO based on the second validity judgment rule.

[0221] Table 2

[0222] Referring to FIG. 3, FIG. 3 is a schematic diagram of judging the validity of the first RO according to the embodiment of the present disclosure. As shown in FIG. 3, the first RO is determined according to the first random access configuration parameter set. If the validity judgment rule is determined to be the first validity judgment rule, the first validity judgment rule is used for the first RO, and then the valid RO can be located in the uplink symbol (U) or the flexible symbol (F). If the validity judgment rule is determined to be the second validity judgment rule, the second validity judgment rule is used for the first RO, and then the valid RO can be located in the uplink available physical resource block (UL usable PRB) on the SBFD symbol of the downlink symbol (D). The uplink available PRB is the frequency domain resource overlapping the SBFD uplink subband and the uplink BWP in the SBFD symbol.

[0223] In a second case, when the first indication information is not defined and the second indication information is defined, the validity determination rule is determined based on a configuration of the second indication information.

[0224] Based on this, in some embodiments, when the first indication information and / or the second indication information is defined, the validity determination rule is determined based on a configuration of the first indication information and / or the second indication information, including:

[0225] In the second case, when the first indication information is not defined and the second indication information is defined, the validity determination rule is determined based on a configuration of the second indication information.

[0226] In some embodiments, the validity determination rule is determined based on the configuration of the second indication information, including:

[0227] If the network device does not configure the second indication information, the validity determination rule is determined as a first validity determination rule; the first validity determination rule is used to determine the validity of the first RO.

[0228] Alternatively,

[0229] If the network device configures the second indication information, and all parameters in the second random access configuration parameter set associated with the second indication information are not configured with parameter values, the validity determination rule is determined as a second validity determination rule; the second validity determination rule is used to determine the validity of the first RO.

[0230] Alternatively,

[0231] If the network device configures the second indication information, and at least one parameter in the second random access configuration parameter set associated with the second indication information is configured with a parameter value, the validity determination rule is determined as a first validity determination rule and a third validity determination rule; the first validity determination rule is used to determine the validity of the first RO; the third validity determination rule is used to determine the validity of the second RO.

[0232] The first validity determination rule is different from the second validity determination rule and the third validity determination rule.

[0233] In some embodiments, the second random access configuration parameter set includes:

[0234] one or more first type random access configuration parameters;

[0235] and,

[0236] one or more second type random access configuration parameters.

[0237] wherein the first type is different from the second type.

[0238] It can be understood that, for a first type of random access configuration parameter in the second set of random access configuration parameters, if the value of the first type of random access configuration parameter is not explicitly indicated in the second indication information, the terminal considers that the value of the parameter is equal to the value of the parameter corresponding to the parameter in the first set of random access configuration parameters. For a second type of random access configuration parameter in the second set of random access configuration parameters, if the value of the second type of random access configuration parameter is not explicitly indicated in the second indication information, the terminal considers that the parameter is not configured.

[0239] Table 3 is a schematic of the first message, i.e., the SIB1 message. As shown in Table 3, the second indication information, i.e., rach-ConfigCommonSBFD, is defined (may also be described as introduced) in the SIB1 message, and the second indication information can include a second set of random access configuration parameters, which is used to represent {rach-ConfigGeneric, …, featureCombinationPreamblesList-r17}. Some parameters in the second set of random access configuration parameters can also include some other parameters (for example, rach-ConfigGeneric itself includes multiple parameters), and the second set of random access configuration parameters includes one or more first type of random access configuration parameters (for example, prach-ConfigurationIndex, msg1-FDM, msg1-FrequencyStart, totalNumberOfRA-Preambles, ssb-perRACH-OccasionAndCB-PreamblesPerSSB) and one or more second type of random access configuration parameters. If the value of prach-ConfigurationIndex is not explicitly indicated in the second indication information, the UE considers that the value of the parameter is equal to the value of the parameter corresponding to the parameter in the first set of random access configuration parameters, i.e., the value of prach-ConfigurationIndex in rach-ConfigCommon in the SIB1 message. If the value of groupBconfigured is not explicitly indicated in the second indication information, the UE considers that the parameter is not configured.

[0240] Table 3

[0241] Here, the first validity judgment rule includes:

[0242] In the case that the terminal is not provided with tdd-UL-DL-ConfigurationCommon by the network, the valid RO is not before the SS / PBCH block in the PRACH slot, and the valid RO starts at least Ngap symbols after the last SS / PBCH block transmission symbol; where Ngap is an integer greater than or equal to 0;

[0243] Or,

[0244] In the case that the terminal is provided with tdd-UL-DL-ConfigurationCommon by the network, the valid RO is within the UL symbol; or, the valid RO is not before the SS / PBCH block in the PRACH slot, and the valid RO starts at least Ngap symbols after the last downlink symbol, and the valid RO starts at least Ngap symbols after the last SS / PBCH block transmission symbol; where Ngap is an integer greater than or equal to 0.

[0245] For example, in the case that the first indication information is not defined and the second indication information is defined, if the network device does not configure the second indication information, the first validity judgment rule is adopted for the first RO.

[0246] Here, the second validity judgment rule includes:

[0247] The valid RO is located in the uplink available physical resource blocks (PRBs) on the SBFD symbol configured by the network device as a downlink symbol through the first instruction; the uplink available PRBs are the frequency domain resources of the SBFD uplink sub-band overlapping with the uplink BWP in the SBFD symbol.

[0248] That is, the second validity rule at least allows the valid RO to be located in the uplink available physical resource blocks (UL usable PRBs) on the SBFD symbol indicated as a downlink symbol by the first instruction (tdd-UL-DL-ConfigurationCommon); the uplink available PRBs are the frequency domain resources of the SBFD uplink sub-band overlapping with the uplink BWP in the SBFD symbol.

[0249] For example, in the case that the first indication information is not defined and the second indication information is defined, if the network device configures the second indication information, and all parameters in the second random access configuration parameter set associated with the second indication information are not configured with parameter values, the second validity judgment rule is adopted for the first RO.

[0250] In some embodiments, the third validity determination rule comprises:

[0251] The valid RO is located in uplink available PRBs on an SBFD symbol configured by the first instruction as a downlink symbol or a flexible symbol; the uplink available PRBs are frequency domain resources of an SBFD uplink subband in the SBFD symbol and an uplink BWP.

[0252] That is, the third validity determination rule at least allows the valid RO to be located in uplink available physical resource blocks (UL usable PRBs) on an SBFD symbol indicated by the first instruction (tdd-UL-DL-ConfigurationCommon) as a downlink symbol (D) or a flexible symbol (flexible), the UL usable PRBs being frequency domain resources of an SBFD uplink subband in the SBFD symbol and an uplink BWP.

[0253] For example, in the case where the first indication information is not defined and the second indication information is defined, if the network device configures the second indication information and at least one parameter configuration parameter value in the second random access configuration parameter set associated with the second indication information, the first validity determination rule is adopted for the first RO and the third validity determination rule is adopted for the second RO.

[0254] Here, taking the first message as the SIB1 message as an example, assuming that the first indication information, i.e., the parameter rachSBFD, is not defined (or can be described as not introduced) in the common random access configuration (rach-ConfigCommon) in the SIB1 message, and the second indication information, i.e., the parameter rach-ConfigCommonSBFD, is defined (or can be described as introduced) in the SIB1 message, the first RO is determined according to the first random access configuration parameter set associated with rach-ConfigCommon in the SIB1 message; the second RO is determined according to the second random access configuration parameter set associated with rach-ConfigCommonSBFD in the SIB1 message, and the validity determination rule of the first RO and / or the second RO can include the following:

[0255] If the SIB1 message does not configure the second indication information, i.e., rach-ConfigCommonSBFD, the terminal such as a UE determines whether the first RO is a valid RO based on the first validity determination rule;

[0256] Or,

[0257] If the SIB1 message configures the second indication information, i.e., rach-ConfigCommonSBFD, and none of the parameters in the second random access configuration parameter set associated with rach-ConfigCommonSBFD is explicitly configured, i.e., all parameters are not configured with parameter values, the UE determines whether the first RO is a valid RO based on the second validity determination rule; if the SIB1 message configures the second indication information, i.e., rach-ConfigCommonSBFD, and at least one parameter in the second random access configuration parameter set associated with rach-ConfigCommonSBFD is explicitly configured, i.e., at least one parameter is configured with a parameter value, the UE determines whether the first RO is a valid RO based on the first validity determination rule, and determines whether the second RO is a valid RO based on the third validity determination rule.

[0258] Referring to FIG. 4, FIG. 4 is a schematic diagram of determining the validity of the first RO and the second RO according to an embodiment of the present disclosure. As shown in FIG. 4, the first RO is an RO determined according to the first random access configuration parameter set, and the second RO is an RO determined according to the second random access configuration parameter set. If the validity determination rule is determined to be the first validity determination rule, the first validity determination rule is used for the first RO, and then the valid RO is located in the uplink symbol (U) or the flexible symbol (F). Alternatively, if the validity determination rule is determined to be the second validity determination rule, the second validity determination rule is used for the first RO, and then the valid RO can be located in the uplink usable physical resource block (UL usable PRB) on the SBFD symbol of the downlink symbol (D); the uplink usable PRB is the frequency domain resource of the SBFD uplink sub-band overlapping with the uplink BWP in the SBFD symbol. If the validity determination rule is determined to be the third validity determination rule, the third validity determination rule is used for the second RO, and then the valid RO can be located in the uplink usable physical resource block (UL usable PRB) on the SBFD symbol of the downlink symbol (D); the uplink usable PRB is the frequency domain resource of the SBFD uplink sub-band overlapping with the uplink BWP in the SBFD symbol.

[0259] Referring to FIG. 5, FIG. 5 is a schematic diagram of determining validity of the first RO and the second RO according to an embodiment of the present disclosure. As shown in FIG. 5, the first RO is determined according to a first set of random access configuration parameters, and the second RO is determined according to a second set of random access configuration parameters. If it is determined that the validity determination rule is the first validity determination rule, the first validity determination rule is used for the first RO, and then the valid RO is located in an uplink symbol (U) or a flexible symbol (F). If it is determined that the validity determination rule is the second validity determination rule, the second validity determination rule is used for the first RO, and then the valid RO can be located in an uplink usable physical resource block (UL usable PRB) on a SBFD symbol of a downlink symbol (D); the uplink usable PRB is a frequency domain resource in which a SBFD uplink subband in the SBFD symbol overlaps with an uplink BWP. If it is determined that the validity determination rule is the third validity determination rule, the third validity determination rule is used for the second RO, and then the valid RO can be located in an uplink usable physical resource block (UL usable PRB) on a SBFD symbol of a downlink symbol (D) or a flexible symbol (F); the uplink usable PRB is a frequency domain resource in which a SBFD uplink subband in the SBFD symbol overlaps with an uplink BWP.

[0260] In a third case, in a case where both the first indication information and the second indication information are defined, the validity determination rule is determined based on a configuration of the first indication information and the second indication information.

[0261] Based on this, in some embodiments, in a case where the first indication information and / or the second indication information is defined, the validity determination rule is determined based on a configuration of the first indication information and / or the second indication information, including:

[0262] In a case where both the first indication information and the second indication information are defined, the validity determination rule is determined based on a configuration of the first indication information and the second indication information.

[0263] As an example, in a case where both the first indication information and the second indication information are defined, the first indication information and the second indication information can be the same parameter information, for example, the same parameter rach-ConfigCommonSBFD is used to represent the first indication information and the second indication information.

[0264] In some embodiments, the validity determination rule is determined based on the configuration of the first indication information and the second indication information, including:

[0265] If the network device is not configured with the first indication information and is not configured with the second indication information, it is determined that the validity judgment rule is a first validity judgment rule; the first validity judgment rule is used to judge the validity of the first RO.

[0266] Alternatively,

[0267] If the network device is configured with the first indication information and is not configured with the second indication information, it is determined that the validity judgment rule is a second validity judgment rule; the second validity judgment rule is used to judge the validity of the first RO.

[0268] Alternatively,

[0269] If the network device is configured with the first indication information, the state of the first indication information is an invalid state, and is not configured with the second indication information, it is determined that the validity judgment rule is a first validity judgment rule; the first validity judgment rule is used to judge the validity of the first RO.

[0270] Alternatively,

[0271] If the network device is configured with the first indication information, the state of the first indication information is an effective state, and is not configured with the second indication information, it is determined that the validity judgment rule is a second validity judgment rule; the second validity judgment rule is used to judge the validity of the first RO.

[0272] Alternatively,

[0273] If the network device is not configured with the first indication information and is configured with the second indication information, it is determined that the validity judgment rule is a first validity judgment rule and a third validity judgment rule; the first validity judgment rule is used to judge the validity of the first RO; the third validity judgment rule is used to judge the validity of the second RO.

[0274] Alternatively,

[0275] If the network device is configured with the first indication information and is configured with the second indication information, it is determined that the validity judgment rule is a first validity judgment rule, a second validity judgment rule and a third validity judgment rule; the first validity judgment rule and the second validity judgment rule are used to judge the validity of the first RO; the third validity judgment rule is used to judge the validity of the second RO.

[0276] The first validity judgment rule is different from the second validity judgment rule and the third validity judgment rule.

[0277] As an example, the first indication information has at least two states, namely an invalid state and an effective state.

[0278] Specifically, the state of the first indication information is an invalid state, which can be understood as that the value of the parameter corresponding to the first indication information is disable or false; the state of the first indication information is a valid state, which can be understood as that the value of the parameter corresponding to the first indication information is enable or true.

[0279] Here, the first validity determination rule includes:

[0280] In the case that the terminal is not provided with tdd-UL-DL-ConfigurationCommon by the network, the valid RO is not before a synchronization signal (SS) / physical broadcast channel (PBCH) block in a PRACH slot, and the valid RO starts at least Ngap symbols after the last SS / PBCH block transmission symbol; where Ngap is an integer greater than or equal to 0;

[0281] Or,

[0282] In the case that the terminal is provided with tdd-UL-DL-ConfigurationCommon by the network, the valid RO is within an UL symbol; or, the valid RO is not before a SS / PBCH block in a PRACH slot, and the valid RO starts at least Ngap symbols after the last downlink symbol and at least Ngap symbols after the last SS / PBCH block transmission symbol; where Ngap is an integer greater than or equal to 0.

[0283] For example, in the case that the first indication information and the second indication information are both defined, if the network device does not configure the first indication information and does not configure the second indication information, or if the network device configures the first indication information, the state of the first indication information is invalid, and does not configure the second indication information, the first validity determination rule is adopted for the first RO.

[0284] Here, the second validity determination rule includes:

[0285] The valid RO is located in the uplink PRBs on the SBFD symbol that the network device configures as a downlink symbol through the first instruction; the uplink available PRBs are frequency domain resources overlapping the SBFD uplink sub-band and the uplink BWP in the SBFD symbol.

[0286] For example, in a case where the first indication information and the second indication information are both defined, if the network device configures the first indication information and does not configure the second indication information, the second validity determination rule is adopted for the first RO; or, if the network device configures the first indication information, the state of the first indication information is the effective state, and does not configure the second indication information, the second validity determination rule is adopted for the first RO.

[0287] Here, the third validity determination rule comprises:

[0288] The valid RO is located in uplink available PRBs on an SBFD symbol configured as a downlink symbol or a flexible symbol by the network device through a first instruction; the uplink available PRBs are frequency domain resources of an SBFD uplink subband and an uplink BWP in the SBFD symbol.

[0289] For example, in a case where the first indication information and the second indication information are both defined, if the network device does not configure the first indication information and configures the second indication information, the first validity determination rule is adopted for the first RO, and the third validity determination rule is adopted for the second RO; or, if the network device configures the first indication information and configures the second indication information, the first validity determination rule and the second validity determination rule are adopted for the first RO, and the third validity determination rule is adopted for the second RO.

[0290] In the embodiments of the present disclosure, the following advantages are provided:

[0291] (1) In a case where the first indication information and / or the second indication information are defined, the terminal can determine the validity determination rule based on the configuration of the network to the first indication information and / or the second indication information. Thus, when a TDD carrier is configured to perform SBFD operation, for a terminal supporting a specific function such as SBFD function, the appropriate validity determination rule can be determined in combination with the configuration of the network to the first indication information and / or the second indication information, which provides a more flexible validity determination manner, thereby realizing wide application range, and also can reduce the occurrence of problems such as random access resource collision and random access time delay increase.

[0292] (2) providing a second validity judgment rule and a third validity judgment rule; wherein the second validity judgment rule specifies that the valid RO is located in the uplink available PRBs on the SBFD symbol configured by the network device as a downlink symbol through the first instruction, and the third validity judgment rule specifies that the valid RO is located in the uplink available PRBs on the SBFD symbol configured by the network device as a downlink symbol or a flexible symbol through the first instruction, wherein the uplink available PRBs are frequency domain resources of the SBFD uplink subband in the SBFD symbol and the uplink BWP.

[0293] In this way, when a TDD carrier is configured to perform SBFD operation, for a terminal (SBFD aware UE) supporting SBFD function, in addition to being able to send a random access preamble in an uplink time slot (UL-only slot) / uplink symbol (UL-only symbol), it can also send a random access preamble in the SBFD uplink subband (SBFD-UL subband) of the SBFD symbol, thereby increasing the capacity of random access resources, reducing the latency of random access, reducing the collision of random access resources, and improving the coverage capability of the PRACH channel.

[0294] Referring to FIG. 6, FIG. 6 is a flowchart illustrating an implementation of the information processing method according to an embodiment of the present disclosure, applied to a network device. As shown in FIG. 6, the method comprises the following step 601:

[0295] Step 601: sending first indication information and / or second indication information to a terminal;

[0296] The first indication information and / or the second indication information are used by the terminal to determine a validity judgment rule in the case where the first indication information and / or the second indication information are defined; based on the validity judgment rule, the validity of the first RO and / or the second RO is judged; wherein the first indication information and the second indication information are different; the first RO is an RO determined by the terminal according to a first random access configuration parameter set; the second RO is an RO determined by the terminal according to a second random access configuration parameter set; the first random access configuration parameter set and the second random access configuration parameter set are different.

[0297] As an example, the first indication information being defined can be understood as the terminal and the network device both understanding the specific meaning of the first indication information, or the terminal and the network device having previously agreed on an information parameter with a specific meaning.

[0298] As an example, the second indication information is defined can be understood as the specific meaning of the second indication information that the terminal and the network device can understand, or the information parameter that the terminal and the network device predefine a specific meaning.

[0299] In some embodiments, the first indication information is a newly defined information element (IE) in a common random access configuration (rach-ConfigCommon) message contained in a system information block 1 (SIB1) message; and the second indication information is a newly defined common random access configuration (rach-ConfigCommonSBFD) for SBFD in the SIB1 message.

[0300] As an example, the newly defined IE can be specifically rachSBFD ENUMERATED{true}OPTIONAL.

[0301] As an example, rach-ConfigCommonSBFD can also be described as SetupRelease{RACH-ConfigCommon}.

[0302] In the existing conventional TDD system, the terminal judges whether the RO configured by the network is a valid RO in the existing manner, and sends a random access preamble on the valid RO. However, the existing manner of judging the validity of the RO is relatively fixed, that is, the valid RO is in the uplink (UL) symbol. Therefore, when a TDD carrier is configured to perform SBFD operation, the terminal supporting the SBFD function can only send a random access preamble on the UL symbol, which may cause collision of random access resources, thereby increasing the delay of random access. That is, the existing manner of judging the validity of the RO may not be applicable to the terminal supporting the SBFD function.

[0303] Therefore, in the embodiments of the present disclosure, when the first indication information and / or the second indication information is defined, the terminal determines the validity judgment rule based on the configuration of the network to the first indication information and / or the second indication information. Thus, when a TDD carrier is configured to perform SBFD operation, for the terminal supporting a specific function such as the SBFD function, a suitable validity judgment rule can be determined in combination with the configuration of the network to the first indication information and / or the second indication information, thereby providing a more flexible validity judgment manner, so as to achieve a wide application range, and also to reduce the occurrence of problems such as collision of random access resources, increase of random access delay, and the like.

[0304] In some embodiments, the sending of the first indication information and / or the second indication information to the terminal comprises:

[0305] sending a first message to the terminal;

[0306] wherein the first message comprises the first indication information and / or the second indication information.

[0307] In some embodiments, in a case that the first indication information is defined and the second indication information is not defined, if the first message does not comprise the first indication information, the network device does not configure the first indication information;

[0308] or,

[0309] In a case that the first indication information is defined and the second indication information is not defined, if the first message comprises the first indication information, the network device configures the first indication information;

[0310] or,

[0311] In a case that the first indication information is not defined and the second indication information is defined, if the first message does not comprise the second indication information, the network device does not configure the second indication information;

[0312] or,

[0313] In a case that the first indication information is not defined and the second indication information is defined, if the first message comprises the second indication information, the network device configures the second indication information;

[0314] or,

[0315] In a case that the first indication information and the second indication information are both defined, if the first message does not comprise the first indication information and does not comprise the second indication information, the network device does not configure the first indication information and does not configure the second indication information;

[0316] or,

[0317] In a case that the first indication information and the second indication information are both defined, if the first message comprises the first indication information and does not comprise the second indication information, the network device configures the first indication information and does not configure the second indication information;

[0318] or,

[0319] In a case that the first indication information and the second indication information are both defined, if the first message does not comprise the first indication information and comprises the second indication information, the network device does not configure the first indication information and configures the second indication information;

[0320] or,

[0321] In the case that the first indication information and the second indication information are both defined, if the first message contains the first indication information and contains the second indication information, the network device configures the first indication information and configures the second indication information.

[0322] Currently, a base station uses a TDM manner on a TDD carrier to perform uplink and downlink multiplexing transmission. In a traditional TDD system, the terminal judges whether a physical random access channel occasion (RO) configured by the network is a valid RO according to an existing manner, and sends a random access preamble on the valid RO. However, the existing manner of judging the validity of the RO is relatively fixed, and cannot judge the validity of the RO according to the network configuration. Thus, when a TDD carrier is configured to perform sub-band non-overlapping full duplex (SBFD) operation, the existing manner of judging the validity of the RO may not be applicable to terminals supporting specific functions, such as terminals supporting the SBFD function.

[0323] Based on this, in the embodiments of the present disclosure, the terminal can also determine an effectiveness judgment rule based on whether the first random access configuration parameter set contains third indication information and / or based on whether the second random access configuration parameter set contains fourth indication information; the first random access configuration parameter set and the second random access configuration parameter set are different; the third indication information and the fourth indication information are the same or different; and the effectiveness of the first RO and / or the second RO is judged based on the effectiveness judgment rule; the first RO is an RO determined by the terminal according to the first random access configuration parameter set; and the second RO is an RO determined by the terminal according to the second random access configuration parameter set.

[0324] Referring to FIG. 7, FIG. 7 is a flowchart of an information processing method according to an embodiment of the present disclosure, which is applied to a terminal, which can be a terminal supporting the SBFD function (SBFD aware UE). As shown in FIG. 7, the method includes steps 701 to 702:

[0325] Step 701: Determine an effectiveness judgment rule based on whether the first random access configuration parameter set contains third indication information and / or based on whether the second random access configuration parameter set contains fourth indication information; the first random access configuration parameter set and the second random access configuration parameter set are different; and the third indication information and the fourth indication information are the same or different.

[0326] As an example, the network device can indicate (or configure) one or more sets of random access configuration parameters, i.e., the first set of random access configuration parameters and / or the second set of random access configuration parameters. Among them, the first set of random access configuration parameters can be specifically a set of random access configuration parameters associated with rach-ConfigCommon or msgA-ConfigCommon-r16 in the SIB1 message; the second set of random access configuration parameters can be specifically a set of random access configuration parameters associated with one AdditionalRACH-Config-r17 in the AdditionalRACH-ConfigList-r17 list in the SIB1 message.

[0327] As an example, the third indication information can be indicated (or configured) in the first set of random access configuration parameters; or the third indication information can not be indicated (or configured); or the third indication information can be indicated as valid or invalid. Among them, valid can be represented by enable, enable, or true; invalid can be represented by disable or false.

[0328] As an example, the fourth indication information can be indicated (or configured) in the second set of random access configuration parameters; or the fourth indication information can not be indicated (or configured); or the fourth indication information can be indicated as valid or invalid. Among them, valid can be represented by enable, enable, or true; invalid can be represented by disable or false.

[0329] It can be understood that if the first set of random access configuration parameters indicates (or configures) the third indication information, or the third indication information can be indicated as valid, it means that the first set of random access configuration parameters contains the third indication information. Similarly, if the second set of random access configuration parameters indicates (or configures) the fourth indication information, or the fourth indication information can be indicated as valid, it means that the second set of random access configuration parameters contains the fourth indication information.

[0330] As an example, the first set of random access configuration parameters and the third indication information can be sent separately or simultaneously by the network device to the terminal; the second set of random access configuration parameters and the fourth indication information can be sent separately or simultaneously by the network device to the terminal.

[0331] In some embodiments, the third indication information is a feature combination indication for implementing the SBFD function; or the third indication information is one of the first set of random access configuration parameters, and the parameter contains a feature combination indication for implementing the SBFD function; or the fourth indication information is a feature combination indication for implementing the SBFD function; or the fourth indication information is one of the second set of random access configuration parameters, and the parameter contains a feature combination indication for implementing the SBFD function.

[0332] Table 4 is a schematic diagram of the third indication information. As shown in Table 4, the third indication information can be a feature combination (FeatureCombination) indication for implementing the SBFD function, i.e., the third indication information is a FeatureCombination indication indicating sbfd-r19; or the third indication information can be one of the first set of random access configuration parameters, and the parameter contains a feature combination (FeatureCombination) indication for implementing the SBFD function, where the parameter can be FeatureCombinationPreambles or featureCombinationPreamblesList.

[0333] Table 4

[0334] In the existing conventional TDD system, a terminal determines whether a network-configured RO is a valid RO in the existing manner, and transmits a random access preamble on the determined valid RO. However, the existing manner of determining the validity of an RO is relatively fixed, i.e., a valid RO is in an uplink (UL) symbol, so when a TDD carrier is configured to perform SBFD operation, a terminal supporting the SBFD function can only transmit a random access preamble on the UL symbol, which may cause collision of random access resources, thereby increasing the latency of random access, i.e., the existing manner of determining the validity of an RO can not be applicable to a terminal supporting the SBFD function.

[0335] Therefore, in the embodiments of the present disclosure, the terminal determines the validity judgment rule based on whether the first random access configuration parameter set contains the third indication information and / or based on whether the second random access configuration parameter set contains the fourth indication information. In this way, when one TDD carrier is configured to perform SBFD operation, the terminal supporting specific functions such as SBFD function can determine a suitable validity judgment rule in combination with the configuration of the third indication information and / or the fourth indication information, thereby providing a more flexible validity judgment manner, so as to achieve a wide application range, and also to reduce the occurrence of problems such as random access resource collision and increased random access delay.

[0336] Step 702: determining the validity of the first RO and / or the second RO based on the validity judgment rule; the first RO is an RO determined by the terminal according to the first random access configuration parameter set; and the second RO is an RO determined by the terminal according to the second random access configuration parameter set.

[0337] In some embodiments, the determining the validity judgment rule based on whether the first random access configuration parameter set contains the third indication information comprises:

[0338] In a case where the network device configures the first random access configuration parameter set, if the first random access configuration parameter set does not contain the third indication information, the validity judgment rule is determined as a first validity judgment rule; the first validity judgment rule is used to determine the validity of the first RO.

[0339] Alternatively,

[0340] In a case where the network device configures the first random access configuration parameter set, if the first random access configuration parameter set contains the third indication information, the validity judgment rule is determined as a second validity judgment rule; the second validity judgment rule is used to determine the validity of the first RO.

[0341] The first validity judgment rule is different from the second validity judgment rule.

[0342] In some embodiments, the determining the validity judgment rule based on whether the second random access configuration parameter set contains the fourth indication information comprises:

[0343] In a case where the network device configures the second random access configuration parameter set, if the second random access configuration parameter set does not contain the fourth indication information, the validity judgment rule is determined as a first validity judgment rule; the first validity judgment rule is used to determine the validity of the first RO.

[0344] Alternatively,

[0345] In a case where the network device configures the second set of random access configuration parameters, if the second set of random access configuration parameters contains fourth indication information, the validity determination rule is determined to be a third validity determination rule; the third validity determination rule is used to determine the validity of the second RO.

[0346] The first validity determination rule is different from the third validity determination rule.

[0347] In some embodiments, the first validity determination rule includes:

[0348] In a case where the terminal is not provided with tdd-UL-DL-ConfigurationCommon by the network, the valid RO is not before the SS / PBCH block in the PRACH slot, and the valid RO starts at least Ngap symbols after the last SS / PBCH block transmission symbol; where Ngap is an integer greater than or equal to 0.

[0349] Or,

[0350] In a case where the terminal is provided with tdd-UL-DL-ConfigurationCommon by the network, the valid RO is within the UL symbol; or, the valid RO is not before the SS / PBCH block in the PRACH slot, and the valid RO starts at least Ngap symbols after the last downlink symbol, and the valid RO starts at least Ngap symbols after the last SS / PBCH block transmission symbol; where Ngap is an integer greater than or equal to 0.

[0351] For example, if the first set of random access configuration parameters does not contain the third indication information, or if the second set of random access configuration parameters does not contain the fourth indication information, the first validity determination rule is used for the first RO.

[0352] In some embodiments, the second validity determination rule includes:

[0353] The valid RO is located in the uplink available PRBs on the SBFD symbol configured by the network device as a downlink symbol through the first instruction; the uplink available PRBs are frequency domain resources overlapping the SBFD uplink sub-band and the uplink BWP in the SBFD symbol.

[0354] That is, the second validity rule at least allows a valid RO to be located in uplink usable PRBs on a SBFD symbol indicated as a downlink symbol by the first instruction (tdd-UL-DL-ConfigurationCommon); the uplink usable PRBs are frequency domain resources in which a SBFD uplink subband in the SBFD symbol overlaps with an uplink BWP.

[0355] For example, if the first random access configuration parameter set contains third indication information, a second validity judgment rule is adopted for the first RO.

[0356] In some embodiments, the third validity judgment rule comprises:

[0357] A valid RO is located in uplink usable PRBs on a SBFD symbol configured as a downlink symbol or a flexible symbol by the network device through the first instruction; the uplink usable PRBs are frequency domain resources in which a SBFD uplink subband in the SBFD symbol overlaps with an uplink BWP.

[0358] That is, the third validity judgment rule at least allows a valid RO to be located in uplink usable PRBs on a SBFD symbol indicated as a downlink symbol (D) or a flexible symbol (flexible) by the first instruction (tdd-UL-DL-ConfigurationCommon), and the UL usable PRBs are frequency domain resources in which a SBFD uplink subband in the SBFD symbol overlaps with an uplink BWP.

[0359] For example, if the second random access configuration parameter set contains fourth indication information, the third validity judgment rule is adopted for the second RO.

[0360] Figure 8 is a schematic diagram of third indication information. As shown in Figure 8, the third indication information can be a parameter FeatureCombinationPreambles in the first random access configuration parameter set, which contains a feature combination indication for implementing the SBFD function, i.e., featureCombination-r17, wherein featureCombination-r17 can be a FeatureCombination indication indicating sbfd-r19.

[0361] It should be noted that, if the network device indicates the third indication information in FeatureCombinationPreambles in the first set of random access configuration parameters, part of the parameters in FeatureCombinationPreambles are only applied to the valid ROs on non-SBFD (non-SBFD) symbols or slots, or only applied to the valid ROs on symbols indicated by tdd-UL-DL-ConfigurationCommon as uplink symbols or flexible symbols, but not applied to the valid ROs on SBFD symbols indicated by tdd-UL-DL-ConfigurationCommon as downlink symbols; wherein the part of the parameters can at least include startPreambleForThisPartition-r17, or numberOfPreamblesPerSSB-ForThisPartition-r17.

[0362] In the embodiments of the present disclosure, the following advantages are provided:

[0363] (1) The terminal can determine the validity judgment rule based on whether the first set of random access configuration parameters contains the third indication information, and / or based on whether the second set of random access configuration parameters contains the fourth indication information. In this way, when a TDD carrier is configured to perform SBFD operation, the terminal supporting specific functions such as SBFD function can determine the appropriate validity judgment rule in combination with the configuration of the third indication information and / or the fourth indication information, providing a more flexible validity judgment mode, thereby realizing wide application range, and also reducing the occurrence of problems such as random access resource collision and increased random access delay.

[0364] (2) The second validity judgment rule and the third validity judgment rule are provided; wherein the second validity judgment rule specifies that the valid RO is located in the uplink available PRBs on the SBFD symbol configured by the network device as a downlink symbol by the first instruction, and the third validity judgment rule specifies that the valid RO is located in the uplink available PRBs on the SBFD symbol configured by the network device as a downlink symbol or a flexible symbol by the first instruction, wherein the uplink available PRBs are the frequency domain resources of the SBFD uplink subband and the uplink BWP in the SBFD symbol.

[0365] Thus, when a TDD carrier is configured to perform SBFD operation, for a terminal (SBFD aware UE) supporting SBFD function, in addition to being able to send a random access preamble in an uplink time slot (UL-only slot) / uplink symbol (UL-only symbol), it is also able to send a random access preamble in the SBFD uplink subband (SBFD-UL subband) of the SBFD symbol, thereby increasing the capacity of random access resources, reducing the latency of random access, reducing the collision of random access resources, and improving the coverage capability of the PRACH channel.

[0366] Referring to FIG. 9, FIG. 9 is a schematic diagram of an implementation flow of an information processing method according to an embodiment of the present disclosure, applied to a network device. As shown in FIG. 9, the method comprises the following steps:

[0367] Step 901: sending a first random access configuration parameter set and / or a second random access configuration parameter set to a terminal; wherein the first random access configuration parameter set contains third indication information or does not contain the third indication information; the second random access configuration parameter set contains fourth indication information or does not contain the fourth indication information; the third indication information and the fourth indication information are the same or different;

[0368] The third indication information and / or the fourth indication information are used by the terminal to determine an effectiveness determination rule; based on the effectiveness determination rule, the effectiveness of a first RO and / or a second RO is determined; the first RO is an RO determined by the terminal according to the first random access configuration parameter set; and the second RO is an RO determined by the terminal according to the second random access configuration parameter set.

[0369] As an example, the network device can indicate (or configure) one or more random access configuration parameter sets, i.e., the first random access configuration parameter set and / or the second random access configuration parameter set. The first random access configuration parameter set can be a random access configuration parameter set associated with rach-ConfigCommon or msgA-ConfigCommon-r16 in the SIB1 message; and the second random access configuration parameter set can be a random access configuration parameter set associated with one AdditionalRACH-Config-r17 in the AdditionalRACH-ConfigList-r17 list in the SIB1 message.

[0370] As an example, the third indication information can be indicated (or configured) in the first random access configuration parameter set; or, the third indication information can not be indicated (or configured); or, the third indication information can be indicated as valid or invalid. Wherein, valid can be represented by enable enable or true, and invalid can be represented by disable or false.

[0371] As an example, the fourth indication information can be indicated (or configured) in the second random access configuration parameter set; or, the fourth indication information can not be indicated (or configured); or, the fourth indication information can be indicated as valid or invalid. Wherein, valid can be represented by enable enable or true, and invalid can be represented by disable or false.

[0372] It can be understood that, if the first random access configuration parameter set indicates (or configures) the third indication information, or the third indication information can be indicated as valid, it indicates that the first random access configuration parameter set contains the third indication information. Similarly, if the second random access configuration parameter set indicates (or configures) the fourth indication information, or the fourth indication information can be indicated as valid, it indicates that the second random access configuration parameter set contains the fourth indication information.

[0373] As an example, the first random access configuration parameter set and the third indication information can be sent separately or simultaneously by the network device to the terminal; the second random access configuration parameter set and the fourth indication information can be sent separately or simultaneously by the network device to the terminal.

[0374] In some embodiments, the third indication information is a feature combination indication for implementing the SBFD function; or, the third indication information is a parameter in the first random access configuration parameter set, and the parameter contains a feature combination indication for implementing the SBFD function; the fourth indication information is a feature combination indication for implementing the SBFD function; or, the fourth indication information is a parameter in the second random access configuration parameter set, and the parameter contains a feature combination indication for implementing the SBFD function.

[0381] In some embodiments, the apparatus is further configured to:

[0382] In a case where the first indication information is defined and the second indication information is not defined, if the first message does not contain the first indication information, it is determined that the network device does not configure the first indication information;

[0384] In a case where the first indication information is defined and the second indication information is not defined, if the first message contains the first indication information, it is determined that the network device configures the first indication information;

[0385] Or,

[0386] In a case where the first indication information is not defined and the second indication information is defined, if the first message does not contain the second indication information, it is determined that the network device does not configure the second indication information;

[0387] Or,

[0388] In a case where the first indication information is not defined and the second indication information is defined, if the first message contains the second indication information, it is determined that the network device configures the second indication information;

[0389] Or,

[0390] In a case where the first indication information and the second indication information are both defined, if the first message does not contain the first indication information and does not contain the second indication information, it is determined that the network device does not configure the first indication information and does not configure the second indication information;

[0391] Alternatively,

[0392] In a case where the first indication information and the second indication information are both defined, if the first message contains the first indication information and does not contain the second indication information, it is determined that the network device configures the first indication information and does not configure the second indication information;
