[0046] Embodiments of the present disclosure provide a communication method, a terminal, a network device, and a storage medium.

[0047] In a first aspect, an embodiment of the present disclosure provides a communication method, which is executed by a terminal and includes:

[0048] Determine overlap between resources in the first resource set and / or the second resource set and a sub-band full-duplex (SBFD) time unit;

[0049] Among them, the first resource set includes at least one first resource; the second resource set includes at least one second resource; the first resource is the time domain resource and / or frequency domain resource where the effective random access channel opportunity RO is located; the time domain resource of the second resource is a time unit whose resource position is before the resource position of the time domain resource of the first resource.

[0050] In the above embodiment, since the terminal determines that the resources in the first resource set and / or the second resource set overlap with the sub-band full-duplex SBFD time unit, the terminal can perform random access channel access on the SBFD time unit and can also perform downlink data transmission and reception at the same time. Compared with the situation where random access channel access can only be performed on the SBFD time unit, the downlink and uplink resources on the SBFD time unit can be efficiently utilized, thereby improving resource utilization efficiency.

[0051] In conjunction with some embodiments of the first aspect, in some embodiments, the method further includes at least one of the following:

[0052] Determining, according to a predetermined protocol, that resources in the first resource set and / or the second resource set can overlap with the SBFD time unit;

[0053] Configuration information is received, and according to the configuration information, it is determined that resources in the first resource set and / or the second resource set can overlap with the SBFD time unit.

[0054] In some embodiments, the terminal may determine, based on a predetermined protocol and / or received first information, that resources in the first resource set and / or the second resource set can overlap with the SBFD time unit, and the determination method is more flexible.

[0055] In combination with some embodiments of the first aspect, in some embodiments, the frequency domain resources of the second resources are the same as the frequency domain resources of the first resources.

[0056] In the above embodiment, since the frequency domain resource of the second resource is the same as the frequency domain resource of the first resource, the same transmission processing can be performed on the first resource and the second resource.

[0057] In conjunction with some embodiments of the first aspect, in some embodiments, the method further includes:

[0058] receiving a first message;

[0059] The first information is used to determine the first resource set, and the time domain positions of resources in the first resource set and / or the second resource set overlap with the SBFD time unit.

[0060] In the above embodiment, since the first information can be used to determine the first resource set, and the time domain position of the resources in the first resource set and / or the second resource set overlaps with the SBFD time unit, after the terminal receives the first information, it can use the resources in the first resource set and / or the second resource set to perform corresponding transmission operations.

[0061] In conjunction with some embodiments of the first aspect, in some embodiments, the method further includes:

[0062] A first signaling is received, where the first signaling indicates that a downlink (DL) time unit is configured to overlap with the SBFD time unit.

[0063] In the above embodiment, the overlapping may configure the downlink DL time unit as the SBFD time unit through the first signaling.

[0064] In conjunction with some embodiments of the first aspect, in some embodiments, the method further includes:

[0065] It is not expected that the SBFD time units included in the first resource and / or the second resource are configured as DL time units.

[0066] In the above embodiment, since the terminal does not expect the SBFD time units included in the first resource and / or the second resource to be configured as DL time units, the network device may not configure the SBFD time units included in the first resource and / or the second resource as DL time units.

[0067] In conjunction with some embodiments of the first aspect, in some embodiments, the SBFD time unit not expected to be included in the first resource and / or the second resource is configured as a DL time unit, including:

[0068] It is not expected to receive a second signaling; wherein the second signaling is used to configure the SBFD time unit included in the first resource and / or the second resource as a DL time unit.

[0069] In the above embodiment, since the terminal does not expect to receive the second signaling, the network device does not configure the SBFD time units included in the first resource and / or the second resource as DL time units through the second signaling.

[0070] In conjunction with some embodiments of the first aspect, in some embodiments, the method further includes:

[0071] It is not expected that the frequency domain resources of the first resource and the second resource overlap with the SBFD time unit outside the UL transmission frequency range.

[0072] In the above embodiment, since the terminal does not expect the frequency domain resources of the first resource and the second resource to overlap with the SBFD time unit outside the UL transmission frequency range, the network device may not configure the frequency domain resources of the first resource and the second resource to overlap with the SBFD time unit outside the UL transmission frequency range.

[0073] In conjunction with some embodiments of the first aspect, in some embodiments, the frequency domain resources of the first resource and the second resource are not expected to overlap with the SBFD time unit outside the UL transmission frequency range, including:

[0074] It is determined that the first resource and the second resource include the SBFD time unit, and it is not expected that frequency domain resources of the first resource and the second resource overlap with the SBFD time unit outside a UL transmission frequency range.

[0075] In the above embodiment, when the first resource and the second resource include the SBFD time unit, since the terminal does not expect the frequency domain resources of the first resource and the second resource to overlap with the SBFD time unit outside the UL transmission frequency range, the network device may not configure the frequency domain resources of the first resource and the second resource to overlap with the SBFD time unit outside the UL transmission frequency range.

[0076] In combination with some embodiments of the first aspect, in some embodiments, the first signaling is semi-static signaling or dynamic signaling, and / or the second signaling is semi-static signaling or dynamic signaling.

[0085] It is determined that the time unit in which the third resource is located is an SBFD time unit, and the third resource and / or the second resource overlap with the time unit for transmitting a DL signal, and the DL signal is received.

[0086] In the above embodiment, when it is determined that the third resource and / or the second resource overlap with the time unit for transmitting the downlink DL signal, the reception of the DL signal can be canceled and the DL signal is not received; when it is determined that the time unit where the third resource is located is an SBFD time unit and the third resource and / or the second resource overlap with the time unit for transmitting the DL signal, the DL signal can be received and the DL signal is received.

Furthermore, multiple systems may be combined (for example, a combination of LTE or LTE-A with 5G).

[0166] To better understand the embodiments of the present disclosure, the following examples illustrate relevant scenarios:

[0167] In order to improve uplink (UL) coverage and throughput, duplex enhancement (duplex enhancement) has been studied on subband full duplex (SBFD).

[0168] In some embodiments, a carrier component (CC) on a downlink (DL) or flexible (F) symbol is divided into multiple subbands (SBs) in the frequency domain. The multiple SBs include one UL subband and at least one (one or two) DL subbands. A base station can transmit DL signals on the DL subband and simultaneously receive UL signals on the UL subband. DL or F symbols can be configured in at least one of the following ways:

[0169] TDD-UL-DL-ConfigCommon configuration;

[0170] TDD-UL-DL-ConfigDedicated configuration;

[0171] TDD-UL-DL-ConfigCommon and TDD-UL-DL-ConfigDedicated configurations; and

[0172] Downlink control information format 2-0 (DCI format 2-0) indication.

[0173] When a symbol includes both a DL subband and a UL subband in the frequency domain, it may be called an SBFD symbol.

[0174] In some embodiments, when a time slot includes at least one SBFD symbol among multiple symbols, the time slot may be called an SBFD time slot, referring to Figure 1b, time slot 0 is a DL time slot, including 14 DL symbols, time slots 1 to 3 are SBFD time slots, each time slot includes 14 SBFD symbols, and time slot 4 is a UL time slot, including 14 UL symbols.

[0175] In some embodiments, a DL or F symbol can be configured as SBFD via semi-static signaling, referred to as semi-static SBFD. Alternatively, a DL or F symbol can be dynamically signaled as SBFD, referred to as dynamic SBFD. Furthermore, an SBFD symbol can be modified to a DL, UL, or F symbol via dynamic signaling.

[0176] In some embodiments, a guard band (GB) may exist between the DL sub-band and the UL sub-band to reduce interference between DL signals in the DL sub-band and UL signals in the UL sub-band through frequency domain isolation.

[0177] In some embodiments, in an SBFD symbol, the frequency domain range available for UL transmission may be discontinuous, including the following two cases: 1. The GB and DL subbands are not available for UL transmission, and the UL subbands can be used for UL transmission; 2. The DL subbands are not available for UL transmission, and the UL subbands and GBs can be used for UL transmission.

[0178] In some embodiments, in an SBFD symbol, the frequency domain range that can be used for UL transmission can be referred to as the UL frequency domain range, and the frequency domain range that cannot be used for UL transmission can be referred to as outside the UL frequency domain range. Based on the above analysis, it can be seen that the UL frequency domain ranges of non-SBFD symbols and SBFD symbols are different. The UL frequency domain range is the UL frequency domain range on the CC. In an SBFD symbol, the UL frequency domain range on the UL partial bandwidth (BWP, BandWidth Part) refers to the frequency domain range where the BWP overlaps with the UL frequency domain range on the CC. Unless otherwise specified, the UL frequency domain range in this disclosure refers to the UL frequency domain range on the BWP.

[0179] In some embodiments, when the terminal is in the Radio Resource Control (RRC) idle state, the initial access cell will measure information such as the received signal strength of the synchronization broadcast block (SSB) beam and select the optimal SSB beam. In the direction of the optimal SSB beam, a physical random access channel (PRACH) signal is sent at the random access channel occasion (RO) for random access. In addition, in other states, the terminal can also send a PRACH signal at the RO for random access. Random access includes contention-based random access (CBRA) and non-contention-based random access (CFRA). In CBRA, if multiple terminals use the same preamble sequence, that is, the PRACH signals of two terminals collide, the random access will fail.

[0180] In some embodiments, a UE can transmit uplink signals in UL SB during SBFD symbols. Therefore, configuring ROs in SBFD symbols increases the number of ROs compared to configuring ROs only in UL or F symbols. SBFD-aware UEs (UEs that can recognize SBFD symbol configurations) can perform random access using ROs configured in SBFD symbols, reducing access latency and the probability of PRACH signal collisions between different UEs in CBRA.

[0181] In some embodiments, as shown in Figure 1c, after RO configuration, specific criteria are used to determine whether a RO is valid. Only valid ROs can be used to transmit PRACH signals. The relevant conflict handling criteria stipulate that the symbol containing a valid RO cannot receive DL signals. If a valid RO is located in an SBFD symbol, the DL subband containing the valid RO cannot be used for DL ​​transmission, resulting in a waste of frequency domain resources in the DL subband. Furthermore, conflicts between valid ROs and symbol classes do not yet account for the newly introduced SBFD symbols. Therefore, the conflict handling criteria for valid ROs in SBFD symbols need to be updated.

[0182] In some embodiments, see Table 1, which shows how to handle conflicts of valid ROs in different situations:

[0183] Table 1:

[0184] In some embodiments, Dynamic D / U can be DL / UL transmission indicated by DCI; RRC-D / U can be DL / UL transmission configured by RRC; Any-D / U can be RRC-D or Dynamic-D; Semi-D / U can be tdd-UL-DL-ConfigurationCommon or tdd-UL-DL-ConfigurationDedicated configured as DL or UL; SFI-D / U can be SFI in DCI format 2-0 indicating DL or UL; Ngap can be an integer greater than or equal to 0, using the default value in the protocol.

[0185] In some embodiments, see Figure 1d. For mode 1, the symbols in time slots #1 to 2 are configured as DL through tdd-UL-DL-ConfigurationCommon or tdd-UL-DL-ConfigurationDedicated, and overlap with the symbols of valid RO#0, 1, 2, and 3. The UE does not expect this to happen.

[0186] In some embodiments, referring to FIG. 1 d , for mode 2, the symbol in time slot #3 is indicated as DL through SFI, and overlaps with the symbols of valid RO #4, 5. The UE does not expect this to happen.

[0187] In some embodiments, referring to FIG. 1d , for mode 3, there is DL signal transmission in time slot #1, and it overlaps with valid RO #0 and its first Ngap symbols, then the UE does not receive the PDSCH.

[0188] In some embodiments, when a DL symbol is configured as a semi-SBFD symbol through semi-static signaling or indicated as a Dynamic-SBFD symbol through dynamic signaling and overlaps with a valid RO and its first Ngap symbols, it is an error mode (corresponding to modes 1 and 2).

[0189] In some embodiments, when a DL signal overlaps with a Valid RO and its first Ngap symbols, canceling DL signal reception may cause frequency domain resources of the DL subband on the Valid RO and its first Ngap symbols to be unusable.

[0190] FIG2a is an interactive diagram of a communication method according to an embodiment of the present disclosure. As shown in FIG2a, the present disclosure embodiment relates to a communication method for a communication system 100, the method comprising:

[0191] Step S2101: The network device sends first information to the terminal.

[0192] In some embodiments, the terminal receives first information sent by the network device.

[0193] In some embodiments, the terminal determines that resources in the first resource set and / or the second resource set overlap with the SBFD time unit.

[0194] In some embodiments, the network device determines that resources in the first set of resources and / or the second set of resources overlap with the SBFD time unit.

[0195] In some embodiments, the terminal may determine, based on a predetermined protocol or acquired configuration information, that resources in the first resource set and / or the second resource set can overlap with the SBFD time unit.

[0196] Exemplarily, before the terminal receives the first information, the terminal may determine, based on a predetermined protocol or configuration information sent by a network device, that resources in the first resource set and / or the second resource set can overlap with the SBFD time unit.

[0197] In some embodiments, the network device may determine based on a predetermined protocol that resources in the first resource set and / or the second resource set can overlap with the SBFD time unit, or the network device may configure that resources in the first resource set and / or the second resource set can overlap with the SBFD time unit.

[0198] Exemplarily, before the network device sends the first information, the network device may determine based on a predetermined protocol that the resources in the first resource set and / or the second resource set can overlap with the SBFD time unit, or the network device may configure the resources in the first resource set and / or the second resource set to overlap with the SBFD time unit.

[0199] In some embodiments, the time unit may be a symbol, a time slot, a subframe, etc., which is not limited herein. Exemplarily, the time unit is a symbol.

[0200] In some embodiments, each time unit corresponds to a time-frequency domain position.

[0201] In some embodiments, the first resource set includes at least one first resource.

[0202] In some embodiments, each first resource corresponds to a time-frequency domain position.

[0203] In some embodiments, the first resource is a time domain resource and / or a frequency domain resource where a valid random access channel opportunity RO (valid RO) is located.

[0204] In some embodiments, the first resource is a time domain resource and / or a frequency domain resource where a valid RO is located.

[0205] In some embodiments, the second resource set includes at least one second resource.

[0206] In some embodiments, the frequency domain resources of the second resources are the same as the frequency domain resources of the first resources.

[0207] In some embodiments, each second resource corresponds to a time-frequency domain position.

[0208] In some embodiments, the time domain resource of the second resource is a time unit whose resource position is before the resource position of the time domain resource of the first resource.

[0209] In some embodiments, the second resource is Ngap symbols before the valid RO, where Ngap is an integer greater than or equal to 0.

[0210] In some embodiments, the overlapping of resources may be an overlapping of time domain resources and / or frequency domain resources.

[0211] In some embodiments, the terminal receives configuration information sent by the network device, and the terminal determines, according to the configuration information, that resources in the first resource set and / or the second resource set can overlap with the SBFD time unit.

[0212] In some embodiments, the terminal determines, according to a predetermined protocol, that resources in the first resource set and / or the second resource set can overlap with the SBFD time unit.

[0213] In some embodiments, the first information is used to determine the first set of resources.

[0214] In some embodiments, time domain locations of resources in the first resource set and / or the second resource set overlap with the SBFD time unit.

[0215] In some embodiments, the first information is RO configuration information. In some embodiments, the terminal determines the time-frequency domain location of an RO within a configuration period of the RO configuration information. Among the ROs within the configuration period of the RO configuration information, whether the RO is a valid RO may be determined based on a first criterion. The resource corresponding to the time-frequency domain location of the valid RO among the ROs within the configuration period of the RO configuration information may be the first resource. The presently disclosed embodiments do not limit the implementation method of the first criterion.

[0216] In some embodiments, the ROs in the configuration period of the RO configuration information include valid ROs and invalid ROs. The valid ROs may be determined based on a first criterion.

[0217] In some embodiments, all ROs within the configuration period of the RO configuration information may be valid ROs, which is not limited here.

[0218] In some embodiments, the terminal determines the time-frequency domain position of the RO within the configuration period of the RO configuration information, and the resource corresponding to the time-frequency domain position of the RO within the configuration period of the RO configuration information may be the first resource.

[0219] Step S2102: The network device sends a first signaling to the terminal.

[0220] In some embodiments, the terminal receives first signaling sent by the network device.

[0221] In some embodiments, the terminal receives first signaling sent by a network device, where the first signaling indicates that a downlink (DL) time unit is configured as the SBFD time unit.

[0222] Exemplarily, DL symbols may be configured through tdd-UL-DL-ConfigurationCommon signaling.

[0223] Exemplarily, DL symbols may be configured through tdd-UL-DL-ConfigurationDedicated signaling.

[0224] For example, DL symbols may be dynamically indicated through DCI format 2-0 signaling.

[0225] In some embodiments, the terminal does not expect that the SBFD time units included in the first resource and / or the second resource are configured as DL time units.

[0226] Exemplarily, the terminal does not expect at least one of the SBFD symbols included in the valid RO and its first Ngap symbols to be configured as a DL symbol.

[0227] In some embodiments, the terminal does not expect to receive second signaling, wherein the second signaling is used to configure at least one of the SBFD time units included in the first resource and / or the second resource as a DL time unit. In this way, the situation where the SBFD time unit cannot be used for random access due to the SBFD time unit being configured as a DL time unit can be reduced.

[0228] Exemplarily, the UE does not expect to receive second signaling, where the second signaling is used to configure at least one of the SBFD symbols included in the valid RO and its first Ngap symbols as a DL symbol.

[0229] In some embodiments, the terminal does not expect that the frequency domain resources of the first resource and / or the second resource overlap with the SBFD time unit outside the UL transmission frequency range.

[0230] In some embodiments, the terminal determines that the first resource and the second resource include the SBFD time unit, and does not expect that the frequency domain resources of the first resource and / or the second resource overlap with the SBFD time unit outside the UL transmission frequency range.

[0231] In some embodiments, when the symbol where the Valid RO is located and its first Ngap symbols include an SBFD symbol, the terminal does not expect the frequency domain range of the Valid RO to overlap with the SBFD symbol outside the UL transmission frequency range.

[0232] In some embodiments, the first signaling is semi-static signaling or dynamic signaling, and / or the second signaling is semi-static signaling or dynamic signaling.

[0233] In some embodiments, the semi-static signaling is SBFD symbol configuration signaling.

[0234] In some embodiments, the dynamic signaling is downlink control information DCI signaling.

[0235] Exemplarily, see 2b. In time slot #1, the RO uses symbols #2 to 13. One RO contains 6 OS (OFDM symbols), and Ngap is 2. Exemplarily, symbols #0 to 12 in time slot #1 can overlap with the valid RO and its first Ngap symbols. Exemplarily, it is not expected to receive the second signaling, and the second signaling is used to configure the SBFD symbols in symbols #0 to 12 in time slot #1 as DL. It should be noted that if the SBFD symbols are configured as DL, there will be no UL symbols on which random access can be performed on the corresponding symbols. In the embodiment of the present disclosure, since the terminal does not expect to receive the second signaling, the network device may not configure the SBFD as DL through the second signaling. In this way, the terminal can perform random access on the SBFD. Exemplarily, when the symbol where the valid RO is located and its first Ngap symbols contain SBFD symbols, the terminal does not expect the valid RO to overlap with the SBFD symbols outside the UL transmission frequency range, for example, it is not expected that the valid RO includes RO#1 and RO#3.

[0236] It should be noted that the execution order of step S2101 and step S2102 is not limited, and step S2101 can be executed first, or step S2102 can be executed first. The configuration signaling of the first information in step S2101 can also be the first signaling in step S2102, that is, step S2101 and step S2102 can be implemented through the same signaling, for example, RRC signaling.

[0237] In some embodiments, if the RO is configured on the DL symbol, the RO is determined to be an invalid RO; if the RO is configured on the SBFD symbol, the RO may be a valid RO, or, if the RO is configured on the SBFD symbol and the frequency domain range of the RO is within the UL subband, the RO may be a valid RO.

[0238] Step S2103: The network device sends a third signaling to the terminal.

[0239] In some embodiments, the terminal receives third signaling sent by the network device.

[0240] In some embodiments, the third signaling indicates a third resource.

[0241] In some embodiments, the third signaling indicates a fourth resource.

[0242] In some embodiments, the third signaling may be the same configuration information or indication information as the first information, that is, the network device may include the third signaling and the first information in the same information or signaling and send it to the terminal, which is not limited here.

[0243] In some embodiments, the third signaling is different from the signaling used to send the first information, that is, the third signaling is not sent together with the first information through the same signaling.

[0244] In some embodiments, a third resource set and a fourth resource set are determined based on the first resource set.

[0245] In some embodiments, the third resource set includes at least one third resource.

[0246] In some embodiments, the third resource is a resource in the first resource set actually used to send a random access channel PRACH.

[0247] In some embodiments, the fourth resource set includes at least one fourth resource.

[0248] In some embodiments, the fourth resource is a resource in the first resource set excluding the third resource.

[0249] Exemplarily, the first resource is a valid RO, which may be referred to as a nominal valid RO.

[0250] Exemplarily, the valid RO actually used for sending PRACH in the nominal valid RO is the actual valid RO (third resource), and the remaining valid ROs are the fourth resources.

[0251] Step S2104: The terminal performs processing operations.

[0252] In some embodiments, it is determined that the third resource and the second resource overlap with a time unit for transmitting a downlink DL signal, and reception of the DL signal is canceled.

[0253] Exemplarily, the actual valid RO and its first Ngap symbols overlap with symbols corresponding to the DL signal, and the DL signal reception is canceled.

[0254] In some embodiments, it is determined that the time unit in which the third resource is located is a SBFD time unit, and the third resource and the second resource overlap with the time unit for transmitting a DL signal, and the DL signal is received.

[0255] Exemplarily, the symbol where the actual valid RO is located is a SBFD symbol, and the actual valid RO and its first Ngap symbols overlap with the symbol corresponding to the DL signal, then the terminal can receive the DL signal or the terminal can receive a high-priority DL signal.

[0256] In some embodiments, it is determined that the time unit in which the fourth resource is located is a SBFD time unit, and the fourth resource and the second resource overlap with a time unit for transmitting a DL signal, and the DL signal is received.

[0257] Exemplarily, the fourth resource can be a nominal valid RO in addition to the actual valid RO in the first resource, the symbol where the nominal valid RO is located is SBFD, the nominal valid RO and its first Ngap symbols overlap with the symbol corresponding to the DL signal, and the terminal can receive the DL signal or the terminal can receive a high-priority DL signal.

[0258] Exemplarily, referring to Figure 2c, exemplary, reception of PDSCH#2 is canceled; exemplary, PDSCH#2 is received; exemplary, when PDSCH#2 is a high-priority DL signal, PDSCH#2 is received; exemplary, PDSCH#1 is received; exemplary, when PDSCH#1 is a high-priority DL signal, PDSCH#1 is received. It should be noted that when PDSCH#1 overlaps with the nominal valid RO, PDSCH#1 can be received, and therefore, the reception of PDSCH#1 is not canceled; when PDSCH#2 overlaps with the actual valid RO, PDSCH#2 may not be received, and therefore, the reception of PDSCH#2 is canceled.

[0259] In some embodiments, the time unit in which the first resource is located is SBFD, and the first resource and the second resource overlap with the time unit in which a DL signal is transmitted, and a DL signal is received.

[0260] Exemplarily, the symbol where the valid RO is located is SBFD, the valid RO and its first Ngap symbols overlap with the symbol corresponding to the DL signal, and the terminal can receive the DL signal or the terminal can receive a high-priority DL signal.

[0261] In some embodiments, the receiving the DL signal comprises: receiving the DL signal based on a priority of the DL signal.

[0262] In some embodiments, the receiving the DL signal based on the priority of the DL signal comprises:

[0263] receiving the DL signal of high priority, wherein the DL signal of high priority includes at least one of the following:

[0264] DL signal indicated by DCI;

[0265] DL Ultra-Reliable Low-Latency Communications (URLLC) signal.

[0266] In some embodiments, canceling the reception of the DL signal may be canceling the reception of a low priority DL signal.

[0267] In some embodiments, for multiple PDSCH transmissions indicated by a DCI, the high-priority DL signal is the first PDSCH transmission. Multiple PDSCH transmissions indicated by a DCI include at least one of: PDSCH repetition transmission; semi-persistently scheduled (SPS) PDSCH transmission with or without repetition; and multiple PDSCH transmissions scheduled by a single DCI.

[0268] In some embodiments, the term "information" can be interchangeable with terms such as "message", "signal", "signaling", "report", "configuration", "indication", "instruction", "command", "channel", "parameter", "field", and "data".

[0269] In some embodiments, the term "send" can be interchanged with terms such as "transmit", "report", and "transmit".

[0372] In order to better understand the embodiments of the present disclosure, the technical solution of the present disclosure is further described below through an exemplary embodiment:

[0373] Figure 6a is a flow chart of a communication method according to an embodiment of the present disclosure. As shown in Figure 6a, the embodiment of the present disclosure relates to a communication method, which is executed by a communication system. The method includes:

[0374] Step S6101: The terminal receives first information including RO configuration information, and determines the time-frequency position of the RO within the configuration period of the RO according to the RO configuration information.

[0375] Step S6102: Determine the time-frequency position of the valid RO according to the time-frequency position of the RO, and determine the conflict handling between the valid RO and the DL signal, symbol type, etc.

[0376] In some embodiments, a solution 1 is provided: conflicting update of symbol direction configuration and valid RO.

[0377] In some embodiments, Scheme 1-1 is provided:

[0378] In some embodiments, the time domain:

[0379] Exemplarily, the DL symbol is configured as tdd-UL-DL-ConfigurationCommon.

[0380] Exemplarily, the DL symbol is configured as tdd-UL-DL-ConfigurationDedicated.

[0381] Exemplarily, the DL symbol is indicated by DCI format 2-0.

[0382] Exemplarily, the UE does not expect a valid RO and its first Ngap symbols, and dynamic signaling indicates that one SBFD symbol is a DL symbol.

[0383] For example, the UE does not expect a valid RO and its first Ngap symbols, and semi-static signaling configures one SBFD symbol as a DL symbol.

[0384] In some embodiments, the frequency domain:

[0385] Exemplarily, when the symbol where the Valid RO is located and the Ngap symbols before it include an SBFD symbol, it is not expected that the frequency domain range of the Valid RO overlaps with the SBFD symbol outside the UL transmission frequency range.

[0386] Exemplarily, the SBFD symbol is configured through semi-static signaling and / or indicated by dynamic signaling.

[0387] For example, please refer to FIG. 2 b again. In time slot # 1 , RO uses symbols # 2 to 13. One RO includes 6 OFDM symbols (OS). Ngap is 2.

[0388] Exemplarily, symbols #0-12 in slot #1 may overlap with the valid RO and its first Ngap symbols.

[0389] Exemplarily, it is not desired that the SBFD symbols in symbols #0-12 in time slot #1 are statically configured as DL or dynamically indicated as DL.

[0390] Exemplarily, when the symbol where the Valid RO is located and its first Ngap symbols include SBFD symbols, the UE does not expect the valid RO to overlap with the SBFD symbols outside the UL transmission frequency range, such as not expecting the valid RO to include RO#1 and RO#3.

[0391] In some embodiments, a solution 2 is provided: a DL signal conflicts with a valid RO.

[0392] In some embodiments, a solution 2-1 is provided: configuring a valid RO (which may be referred to as a nominal valid RO) that is actually used to send a PRACH (which may be referred to as an actual valid RO):

[0393] In some embodiments, the configuration is an actual valid RO.

[0394] Exemplarily, the actual valid RO and its first Ngap symbols overlap with the DL signal, and the DL signal reception is canceled.

[0395] Exemplarily, the symbol where the actual valid RO is located is SBFD, and the actual valid RO and its first Ngap symbols overlap with the DL signal.

[0396] For example, the UE may receive a DL signal.

[0397] For example, the UE may receive a high priority DL signal.

[0398] In one embodiment, the configuration is a nominally valid RO, the symbol where the nominally valid RO is located is SBFD, and the nominally valid RO and its first Ngap symbols overlap with the DL signal.

[0399] For example, the UE may receive a DL signal.

[0400] For example, the UE may receive a high priority DL signal.

[0401] Please refer to FIG. 2 c again. Exemplarily, the reception of PDSCH# 2 is canceled.

[0402] Exemplarily, PDSCH#2 is received.

[0403] Exemplarily, when PDSCH#2 is a high-priority DL signal, PDSCH#2 is received.

[0404] Exemplarily, PDSCH#1 is received.

[0405] Exemplarily, when PDSCH#1 is a high-priority DL signal, PDSCH#1 is received.

[0406] In some embodiments, solution 2-2 is provided: the symbol where the valid RO is located is SBFD, and the valid RO and its first Ngap symbols overlap with the DL signal:

[0407] For example, the UE may receive a DL signal.

[0408] For example, the UE may receive a high priority DL signal.

[0409] In some embodiments, the high priority DL signal includes:

[0410] The DL signal indicated by the DCI; among them, for multiple PDSCH transmissions indicated by a DCI, the high priority DL signal refers to the first PDSCH transmission. Multiple PDSCH transmissions indicated by a DCI include: PDSCH repetition; SPS (semi-persistent scheduled) PDSCH with / without repetition; Multiple PDSCH scheduled by a single DCI;

[0411] DL URLLC signal.
