[0030] Exemplary embodiments will now be described in detail, examples of which are illustrated in the accompanying drawings. When the following description relates to the drawings, unless otherwise indicated, the same numbers in different drawings denote the same or similar elements. The embodiments described in the following exemplary embodiments do not represent all embodiments consistent with this disclosure.

[0031] The communication methods disclosed herein can be applied to Figure 1 The wireless communication system 100 shown may include network device 110 and terminal 120. It is understood that... Figure 1 The wireless communication system shown is for illustrative purposes only. A wireless communication system may also include other network devices, such as core network equipment, wireless relay equipment, and wireless backhaul equipment. Figure 1 Not shown in the diagram. This disclosure does not limit the number of network devices and terminals included in the wireless communication system.

[0032] It is further understood that the wireless communication system of this disclosure is a network providing wireless communication functionality. The wireless communication system can employ different communication technologies, such as code division multiple access (CDMA), wideband code division multiple access (WCDMA), time division multiple access (TDMA), frequency division multiple access (FDMA), orthogonal frequency-division multiple access (OFDMA), single carrier-frequency division multiple access (SC-FDMA), and carrier sense multiple access with collision avoidance. Based on factors such as capacity, speed, and latency, networks can be categorized as 2G networks, 3G networks, 4G networks, or future evolution networks, such as the 5th generation wireless communication system (5G) network, which can also be referred to as New Radio (NR). For ease of description, this disclosure may sometimes simply refer to the wireless communication network as a network.

[0033] Furthermore, the network device 110 involved in this disclosure can also be referred to as a wireless access network device. This wireless access network device can be: a base station, an evolved Node B (eNB), a home base station, an access point (AP) in a wireless fidelity (WIFI) system, a wireless relay node, a wireless backhaul node, a transmission point (TP), or a TRP, etc. It can also be a gNB in ​​an NR system, or it can be a component or part of a base station. When it is a vehicle-to-everything (V2X) communication system, the network device can also be an in-vehicle device. It should be understood that the specific technologies and specific device forms used in the embodiments of this disclosure are not limited.

[0034] Furthermore, the terminal 120 involved in this disclosure can also be referred to as a terminal device, user equipment (UE), mobile station (MS), mobile terminal (MT), etc., which is a device that provides voice and / or data connectivity to a user. For example, the terminal can be a handheld device with wireless connectivity, an in-vehicle device, etc. Currently, some examples of terminals include: smartphones, pocket personal computers (PPCs), handheld computers, personal digital assistants (PDAs), laptops, tablets, wearable devices, or in-vehicle devices, etc. In addition, when it is a vehicle-to-everything (V2X) communication system, the terminal device can also be an in-vehicle device. It should be understood that the embodiments of this disclosure do not limit the specific technology or specific device form adopted by the terminal.

[0035] In this embodiment, network device 110 and terminal 120 can employ any feasible wireless communication technology to transmit data to each other. The transmission channel corresponding to network device 110 sending data to terminal 120 is called DL, and the transmission channel corresponding to terminal 120 sending data to network device 110 is called UL. It is understood that the network device involved in this embodiment can be a base station. Of course, the network device can also be any other possible network device, and the terminal can be any possible terminal; this disclosure does not impose any limitations.

[0036] To improve UL coverage and throughput, the duplex enhancement project in release 18 will focus on SBFD. For example, a CC (Common Channel) on a DL (Low-Level) or F (F-Level) symbol can be divided into multiple subbands within the frequency domain. These subbands can include one UL subband and at least one DL subband, such as one or two DL subbands. Network devices can transmit DL signals on the DL subband and receive UL signals on the UL subband. The DL or F symbol can be configured using Time Division Duplexing (TDD)-UL-DL-Configuration (ConfigCommon) or TDD-UL-DL-Configuration (ConfigDedicated), or indicated as a DL or F symbol by downlink control information (DCI). The DCI can, for example, use DCI format 2-0.

[0037] A symbol that includes both DL and UL subbands in the frequency domain can be called an SBFD symbol. Similarly, if a time slot contains at least one SBFD symbol among its multiple symbols, then that time slot can be called an SBFD time slot. It is clear that if all the symbols in a time slot are SBFD symbols, then that time slot can be called an SBFD time slot. For example... Figure 2 As shown, the frequency range corresponding to time slot 0 is all DL. Therefore, time slot 0 can be considered a DL time slot. Similarly, time slot 4 is a UL time slot. Time slots 1, 2, and 3 include both UL and DL sub-bands, and therefore can be considered SBFD time slots. Of course, the symbols in the SBFD time slots can be considered SBFD symbols. It can be seen that there can be a certain gap between the UL and DL sub-bands in time slots 1 to 3; this gap can be called the guard band (GB). Frequency domain isolation reduces interference between UL signals in the UL sub-band and DL signals in the DL sub-band. Figure 1 The SBFD scenario shown can be considered as SBFD implemented on a single carrier (CC). Of course, in some cases, SBFD can also be enabled based on carrier aggregation (CA).

[0038] In some embodiments, SBFD can be enabled by using different TDD configurations for different CCs. For example Figure 3 As shown, some of the different CCs are used for DL ​​and one of the different CCs is used for UL. From the perspective of CA, the corresponding symbol in the CA scenario can be considered as the SBFD symbol, and / or the corresponding time slot is the SBFD time slot.

[0039] In other embodiments, in a CA scenario, there exists a CC configured with SBFD, which enables SBFD. For example... Figure 4 As shown, for any CC in a CA scenario, such as Figure 4 CC2 in the example contains both UL and DL subbands, therefore CC2 can be considered to have adopted an SBFD configuration. Thus, from a CA perspective, the corresponding symbol in a CA scenario can be considered an SBFD symbol, and / or the corresponding time slot can be considered an SBFD time slot.

[0040] It is clear that for a symbol to be called an SBFD symbol, it can be considered that in a scenario where SBFD is implemented on a single CC, the symbol simultaneously includes both the UL and DL subbands in the frequency domain. Alternatively, a symbol can be considered to be an SBFD symbol in a scenario where SBFD is implemented based on a CA, where the symbol implements SBFD on a single CC, such as a symbol simultaneously including both the UL and DL subbands in the frequency domain; or, a symbol configured with opposite symbol directions on different CCs, such as one CC being configured as DL and another CC as UL.

[0041] In some embodiments, PUSCH coverage performance and latency can be enhanced and reduced by using Physical Uplink Shared Channel (PUSCH) repetition type B. For example, the symbol positions of the PUSCH actually transmitted by the terminal can be determined based on DCI indication and / or radio resource control (RRC) configuration, as well as the identification of invalid symbols. The PUSCH transmission indicated by the DCI can be cross-slot transmission, i.e., PUSCH is transmitted in multiple time slots.

[0042] In some embodiments, PUSCH repetition type B may include a nominal repetition and an actual repetition. The symbol containing the nominal repetition is determined by the network device through DCI indication and / or RRC configuration, and is used to transmit the PUSCH. The symbol containing the actual repetition is determined by the terminal based on information such as time slot boundaries and the location of invalid symbols, and is used to actually transmit the PUSCH.

[0043] For example, a terminal can determine the start time slot, start symbol S, and duration L of the first nominal copy based on the DCI instruction. For instance, the terminal first determines the start time slot based on the DCI, then determines the start symbol S within the start time slot, and finally determines the first nominal copy based on the duration L. Figure 5 The first PUSCH nominal copy in the database. The terminal can also determine the number of repetitions of the nominal copy based on the repetition count parameter configured in the RRC. The repetition count parameter can be numberOfRepetitions-r16. The terminal combines the DCI and RRC to determine the symbol corresponding to each nominal copy. As... Figure 5In this example, assuming numberOfRepetitions-r16 is 4, the starting symbol S is 0, and the duration of the last symbol L is 6, the symbols corresponding to the first, second, third, and fourth PUSCH nominal replicas are determined. For example, a time slot typically includes 14 symbols.

[0044] The terminal can determine which symbols among the symbols corresponding to each nominal copy are invalid based on the criteria for determining invalid symbols. Furthermore, it can identify the symbols other than invalid symbols as potentially valid symbols. For example, if a nominal copy corresponds to multiple consecutive valid symbols, these valid symbols can be mapped to a single physical copy. Typically, one nominal copy can correspond to one or more physical copies. Of course, if the duration of a nominal copy is one symbol, or if a physical copy has only one symbol, it can be chosen not to send a UL signal. For example... Figure 5 The sixth actual copy of PUSCH is shown. The terminal will not send PUSCH on symbol 4 in the corresponding slot 1.

[0045] It's understandable. Figure 5 The diagonal squares in the third row represent invalid symbols. Some invalid symbols can be DL symbols. That is, invalid symbols can include DL symbols or other possible symbols.

[0046] Therefore, in some embodiments, invalid symbols can be determined by any one or more of the following methods.

[0047] For example, in the RRC configuration of tdd-UL-DL-ConfigurationCommon and / or tdd-UL-DL-ConfigurationDedicated, the DL symbol is configured. It is clear that in some cases, tdd-UL-DL-ConfigurationDedicated may not be configured. Alternatively, tdd-UL-DL-ConfigurationDedicated may only be configured under certain specific circumstances. Of course, this disclosure does not limit the specific scenarios in which tdd-UL-DL-ConfigurationDedicated may be configured or not.

[0048] For example, the positionInBurst of the synchronization signal / physical broadcast channel block (SSB) configured by RRC, that is, the symbol where the SSB is located in ssb-PositionsInBurst is determined to be an invalid symbol.

[0049] For example, symbols that are determined to be invalid symbols based on the InvalidSymbolPattern configured in the RRC and the DCI indication.

[0050] For example, in the physical downlink control channel (PDCCH) configuration system information block (SIB) 1 of RRC, the symbol containing type 0 of PDCCH is determined to be an invalid symbol.

[0051] For example, one or more symbols following the DL symbol in the RRC configuration's tdd-UL-DL-ConfigurationCommon and / or tdd-UL-DL-ConfigurationDedicated may be identified as invalid symbols. These one or more symbols can be determined by the number of invalid symbols for DL-UL switching (numberOfInvalidSymbolsForDL-UL-Switching). The subcarrier spacing (SCS) corresponding to the symbol length can be determined by the reference subcarrier spacing configured in tdd-UL-DL-ConfigurationCommon.

[0052] For example, in a CA scenario, if different cells do not support simultaneous transmission and reception of signals, and these different cells include a first cell and a second cell, a symbol configured to receive SSBs in the first cell will be considered an invalid symbol in the second cell.

[0053] For example, in a CA scenario, if a symbol satisfies any one or more of the following conditions in the first cell, then the symbol is an invalid symbol in the second cell. Here, any cell in the first cell group is an active serving cell.

[0054] The conditions may include:

[0055] 1. This symbol represents either PUSCH repetition type B with Type 1 configured grant (CG) or activated PUSCH repetition type B with Type 2 CG. For PUSCH repetition type B with Type 2 CG, the PUSCH sent during the first repetition is excluded.

[0056] 2. The symbol is configured as a DL symbol in the first cell, or the symbol receives one or more of the following in the first cell: PDCCH, physical downlink shared channel (PDSCH), and channel state information-reference signal (CSI-RS).

[0057] For example, the symbol is configured as a DL symbol in the first cell via tdd-UL-DL-ConfigurationCommon and / or tdd-UL-DL-ConfigurationDedicated. Alternatively, the symbol is configured in the first cell via RRC to receive one or more of PDCCH, PDSCH, and CSI-RS.

[0058] It is understood that the first cell can be a reference cell, and the second cell can be a cell other than the first cell among the serving cells, and the second cell meets at least one of the following conditions: the second cell is an active serving cell; the second cell is configured to handle conflicts arising between the second cell and the first cell.

[0059] For example, the second cell can be configured to enable directionalCollisionHandling-r16, i.e., directionalCollisionHandling-r16 = enabled.

[0060] Of course, the reference cell is the activated service cell.

[0061] For PUSCH repetition type B with Type 1CG, it means that after the terminal is configured by RRC, the terminal waits for a certain activation time, and the terminal can use the configured transmission parameters to periodically send PUSCH repetition type B on the configured time and frequency resources.

[0062] In this context, PUSCH repetition type B with Type 2CG indicates that the RRC configures certain parameters of the UE, such as period, open-loop power control, waveform, redundancy version, repetition count, frequency hopping, and the number of hybrid automatic repeat-request (HARQ) processes. The DCI activates and configures parameters including time-domain resources, frequency-domain resources, demodulation reference signal (DMRS), and modulation and coding scheme (MCS), thereby determining the activation time. PUSCH repetition type B can be periodically transmitted by combining the RRC configuration and the time-frequency resources configured by the DCI activation. The terminal can send signaling from the medium access control element (MAC CE) to confirm the activation or deactivation of PUSCH repetition type B with Type 2CG, thus avoiding confusion between the terminal being configured not to transmit PUSCH in PUSCH repetition type B with Type 2CG and the terminal not transmitting PUSCH when there is no UL signal.

[0063] However, the DL subband in an SBFD symbol cannot be used to transmit UL signals and / or channels. Therefore, the frequency range that can be used for UL transmission differs between SBFD and UL time slots, or between SBFD and UL symbols. When configuring a terminal to transmit PUSCH repetition type B via DCI indication and / or RRC, there is currently no consensus on how to determine invalid symbols in the case of SBFD.

[0064] Therefore, this disclosure provides a communication method, apparatus, device, and storage medium that identifies potentially invalid symbols by indicating whether data transmission is permitted on at least one of SBFD symbols and non-SBFD symbols. This ensures that uplink signals can be transmitted on permitted symbols, improving uplink communication efficiency.

[0065] Figure 6 This is a flowchart illustrating a communication method according to an exemplary embodiment, such as... Figure 6 As shown, the method is executed by the terminal and may include the following steps:

[0066] In step S11, the first information is determined.

[0067] In some embodiments, the terminal may determine first information. This first information may be used to instruct the UL signal to be transmitted on at least one of the SBFD symbol and non-SBFD symbol.

[0068] It is understood that the signals in the various embodiments of this disclosure can be considered to include reference signals and / or channels. For example, UL signals may include PUSCH, sounding reference signals (SRS), etc., and this disclosure does not limit them.

[0069] For example, the first information may be sent by the network device, i.e., the terminal receives the first information sent by the network device to determine whether the UL signal is allowed to be transmitted on SBFD symbols and / or non-SBFD symbols.

[0070] For example, predefined rules can be defined to determine the first information, and the terminal can determine the first information based on the predefined rules to determine whether the UL signal is allowed to be transmitted on SBFD symbols and / or non-SBFD symbols.

[0071] In step S12, based on the first information, invalid symbols in the symbols containing the UL signal are determined.

[0072] In some embodiments, the terminal may determine an invalid symbol in the symbol containing the UL signal based on the first information determined in S11. An invalid symbol can be understood as a symbol on which the UL signal is not permitted to be transmitted.

[0073] For example, if the first information indicates that the UL signal is permitted to be transmitted on an SBFD symbol, the terminal can determine an invalid symbol within the symbol containing the UL signal. It is clear that in this case, the symbol containing the UL signal can include an SBFD symbol.

[0074] For example, if the first information indicates that the UL signal is permitted to be transmitted on a non-SBFD symbol, the terminal can determine an invalid symbol within the symbol containing the UL signal. It is clear that in this case, the symbol containing the UL signal can include non-SBFD symbols.

[0075] For example, if the first information indicates that UL signals are permitted to be transmitted on both SBFD and non-SBFD symbols, the terminal can determine an invalid symbol within the symbol containing the UL signal. It is clear that in this case, the symbol containing the UL signal can include both SBFD and / or non-SBFD symbols.

[0076] Of course, in some embodiments, the method may also include the following steps:

[0077] In step S13, valid symbols that allow the transmission of UL signals are determined based on invalid symbols.

[0078] In some embodiments, the terminal can determine the valid symbol of the symbol containing the UL signal based on the invalid symbol determined in S12. It is understood that a valid symbol can be interpreted as a symbol on which the UL signal is permitted to be transmitted.

[0079] For example, the terminal identifies the symbols corresponding to the UL signal and determines the invalid symbols. The terminal then identifies the symbols other than the invalid symbols among the symbols corresponding to the UL signal as valid symbols.

[0080] For example, you can refer to Figure 5 The third line shown, taking the first nominal copy of the PUSCH as an example, shows that symbols 2 and 5 are determined to be invalid symbols. This nominal copy of the PUSCH corresponds to 6 symbols. The nominal copy of the PUSCH can be understood as the UL signal that the terminal wants to send. Based on the 6 symbols and the 2 determined invalid symbols, the terminal determines the remaining 4 symbols as valid symbols, namely symbols 0, 1, 3, and 4.

[0081] In step S14, a UL signal is sent on the valid symbol.

[0082] In some embodiments, the terminal may transmit a UL signal on a valid symbol.

[0083] For example, still using Figure 5 Taking the first nominal copy of the PUSCH as an example, the terminal determines to send UL signals on symbols 0, 1, 3, and 4. For instance, the first actual copy of the PUSCH is sent on symbols 0 and 1, and the second actual copy of the PUSCH is sent on symbols 3 and 4.

[0084] This disclosure identifies potentially invalid symbols by indicating whether data transmission is permitted on at least one of SBFD symbols and non-SBFD symbols. This ensures that uplink signals can be transmitted on permitted symbols, improving uplink communication efficiency.

[0085] In the communication method provided in this embodiment, step S12, determining the invalid symbol in the symbol containing the UL signal based on the first information, may include: determining the invalid symbol based on preset conditions. The preset conditions correspond to the first information.

[0086] In some embodiments, the terminal may determine an invalid symbol based on preset conditions corresponding to the first information. These preset conditions may include one or more of a first preset condition, a second preset condition, and a third preset condition.

[0087] For example, if the first information indicates that UL signals are allowed to be transmitted on SBFD symbols, and the first information also indicates that UL signals are allowed to be transmitted on non-SBFD symbols, the terminal can determine an invalid symbol based on a first preset condition. It is clear that the first preset condition corresponds to the first information indicating that UL signals are allowed to be transmitted on both SBFD and non-SBFD symbols.

[0088] For example, if the first information indicates that UL signals are allowed to be transmitted on an SBFD symbol, the terminal can determine an invalid symbol based on a second preset condition. It is clear that the second preset condition corresponds to the first information indicating that UL signals are allowed to be transmitted on an SBFD symbol.

[0089] For example, if the first information indicates that UL signals are allowed to be transmitted on non-SBFD symbols, the terminal can determine an invalid symbol based on a third preset condition. It is clear that the third preset condition corresponds to the first information indicating that UL signals are allowed to be transmitted on non-SBFD symbols.

[0090] Based on different situations indicated by the first information, this disclosure can use appropriate preset conditions to determine invalid symbols. This ensures that uplink signals can be transmitted on allowed symbols, improving uplink communication efficiency.

[0091] In the communication method provided in this disclosure embodiment, the first information is used to indicate that the UL signal is transmitted on an SBFD symbol and to indicate that the UL signal is transmitted on a non-SBFD symbol; the preset conditions include at least one of the following: the symbol where the SSB is located is a DL symbol or a flexible F symbol, and the symbol where the SSB is located is an invalid symbol; the symbol where the SSB is located is a DL symbol, an F symbol, or an SBFD symbol, and the symbol where the SSB is located is an invalid symbol; the symbol where the SSB is located is an SBFD symbol, the terminal is configured to perform measurements on the SSB, and the symbol where the SSB is located is an invalid symbol; the symbol where the Type0-PDCCH is located is a DL symbol or an F symbol, and the symbol where the Type0-PDCCH is located is an invalid symbol; the symbol where the Type0-PDCCH is located is a DL symbol, an F symbol, or an SBFD symbol, and the symbol where the Type0-PDCCH is located is an invalid symbol. The following symbols are invalid: The symbol containing Type 0-PDCCH is an SBFD symbol; the terminal is configured to receive DCI on Type 0-PDCCH, and the symbol containing Type 0-PDCCH is invalid; the N symbols following the DL symbol or SBFD symbol are invalid, where N is an integer greater than or equal to 0; the target symbol is configured as a DL symbol in the first cell, and is not an SBFD symbol in the CA scenario; the target symbol is invalid in the second cell, where the serving cell includes the first cell and the second cell, and the second cell is a serving cell different from the first cell; the target symbol is configured as any one of DL symbol, UL symbol, and F symbol in the first cell, and is configured as a UL symbol or F symbol in the second cell, in which case the target symbol is valid.

[0092] In some embodiments, when the first information is used to indicate that the UL signal is transmitted on an SBFD symbol and to indicate that the UL signal is transmitted on a non-SBFD symbol, the terminal may determine an invalid symbol based on any one or more of the following preset conditions. Wherein, when the first information is used to indicate that the UL signal is transmitted on an SBFD symbol and to indicate that the UL signal is transmitted on a non-SBFD symbol, the preset condition may be referred to as the first preset condition.

[0093] For example, the terminal receives first information. This first information is used to indicate that the UL signal is transmitted on an SBFD symbol, and to indicate that the UL signal is transmitted on a non-SBFD symbol. The terminal can then determine an invalid symbol based on any one or more of the following first preset conditions.

[0094] For example, the terminal determines, according to predefined rules, the first information used to indicate whether the UL signal is transmitted on an SBFD symbol and whether the UL signal is transmitted on a non-SBFD symbol. The terminal can then determine an invalid symbol based on any one or more of the following first preset conditions.

[0095] In some embodiments, the first preset condition may include the symbol containing the SSB being either a DL symbol or an F symbol, or the symbol containing the SSB being an invalid symbol. The non-SBFD symbol may include any one or more of the UL symbol, DL symbol, and F symbol.

[0101] In some embodiments, the terminal can configure the symbol where the SSB is located as a DL symbol, an F symbol, or an SBFD symbol using a first parameter. That is, when the terminal determines that the first information is used to indicate that the UL signal is transmitted on an SBFD symbol, or to indicate that the UL signal is transmitted on a non-SBFD symbol, configuring the symbol where the SSB is located as a DL symbol, an F symbol, or an SBFD symbol using the first parameter, then the symbol where the SSB is located is an invalid symbol.

That is, when the terminal determines that the first information is used to indicate that the UL signal is transmitted on an SBFD symbol, or to indicate that the UL signal is transmitted on a non-SBFD symbol, it configures the symbol where the SSB is located as an SBFD symbol using the first parameter. Furthermore, if the terminal is configured to perform measurements on an SSB, then the symbol where the SSB is located is an invalid symbol.

[0106] In some embodiments, the first parameter can be ssb-PositionsInBurst. That is, when the terminal determines that the first information is used to indicate that the UL signal is transmitted on an SBFD symbol, or to indicate that the UL signal is transmitted on a non-SBFD symbol, it configures the symbol where the SSB is located as an SBFD symbol via ssb-PositionsInBurst. Furthermore, if it is determined that the terminal is configured to perform measurements on an SSB, then the symbol where the SSB is located is an invalid symbol.

[0107] In some embodiments, the first preset condition may include the symbol where Type0-PDCCH is located being a DL symbol or an F symbol, or the symbol where Type0-PDCCH is located being an invalid symbol.

[0108] In some embodiments, if the terminal determines that the first information is used to indicate that the UL signal is transmitted on an SBFD symbol, or to indicate that the UL signal is transmitted on a non-SBFD symbol, and determines that the symbol where the Type0-PDCCH is located is a DL symbol or an F symbol, then the symbol where the Type0-PDCCH is located is an invalid symbol.

[0112] In some embodiments, if the terminal determines that the first information is used to indicate that the UL signal is transmitted on an SBFD symbol, or to indicate that the UL signal is transmitted on a non-SBFD symbol, and determines that the symbol where the Type0-PDCCH is located is a DL symbol, an F symbol, or an SBFD symbol, then the symbol where the Type0-PDCCH is located is an invalid symbol.

[0113] In some embodiments, the terminal can configure the symbol where Type0-PDCCH is located as a DL symbol, an F symbol, or an SBFD symbol via a second parameter. That is, when the terminal determines that the first information is used to indicate that the UL signal is transmitted on an SBFD symbol, or to indicate that the UL signal is transmitted on a non-SBFD symbol, configuring the symbol where Type0-PDCCH is located as a DL symbol, an F symbol, or an SBFD symbol via the second parameter, then the symbol where Type0-PDCCH is located is an invalid symbol.

[0114] In some embodiments, the second parameter can be PDCCH-ConfigSIB1. That is, when the terminal determines that the first information is used to indicate that the UL signal is transmitted on an SBFD symbol, or to indicate that the UL signal is transmitted on a non-SBFD symbol, it configures the symbol where Type0-PDCCH is located as a DL symbol, an F symbol, or an SBFD symbol through PDCCH-ConfigSIB1, then the symbol where Type0-PDCCH is located is an invalid symbol.

[0115] In some embodiments, the first preset condition may include the symbol where the Type0-PDCCH is located being an SBFD symbol, the terminal being configured to receive DCI on the Type0-PDCCH, and the symbol where the Type0-PDCCH is located being an invalid symbol.

[0116] In some embodiments, if the terminal determines that the symbol where the Type0-PDCCH is located is an SBFD symbol and the terminal is configured to receive DCI on the Type0-PDCCH, then the symbol where the Type0-PDCCH is located is an invalid symbol, provided that the first information is used to indicate that the UL signal is transmitted on an SBFD symbol and to indicate that the UL signal is transmitted on a non-SBFD symbol.

[0117] In some embodiments, the terminal can configure the symbol containing Type0-PDCCH as an SBFD symbol via a second parameter. That is, when the terminal determines that the first information is used to instruct the UL signal to be transmitted on an SBFD symbol, or to instruct the UL signal to be transmitted on a non-SBFD symbol, it configures the symbol containing Type0-PDCCH as an SBFD symbol via the second parameter. Furthermore, if the terminal is configured to receive DCI on Type0-PDCCH, then the symbol containing Type0-PDCCH is an invalid symbol.

[0118] In some embodiments, the second parameter can be PDCCH-ConfigSIB1. That is, when the terminal determines that the first information is used to indicate that the UL signal is transmitted on an SBFD symbol, and to indicate that the UL signal is transmitted on a non-SBFD symbol, the terminal configures the symbol where Type0-PDCCH is located as an SBFD symbol through PDCCH-ConfigSIB1. And if it is determined that the terminal is configured to receive DCI on Type0-PDCCH, then the symbol where Type0-PDCCH is located is an invalid symbol.

[0119] In some embodiments, the first preset condition may include N symbols following the DL symbol or SBFD symbol, where N symbols are invalid symbols, and N is an integer greater than or equal to 0.

[0120] In some embodiments, when the terminal determines that the first information is used to indicate that the UL signal is transmitted on an SBFD symbol, and to indicate that the UL signal is transmitted on a non-SBFD symbol, the terminal determines the N symbols following the DL symbol or SBFD symbol. Here, N is an integer greater than or equal to 0. The terminal determines that the N symbols following the DL symbol or SBFD symbol are invalid symbols.

[0121] In some embodiments, the terminal can configure the N symbols following the DL symbol or SBFD symbol via a third parameter. That is, when the terminal determines that the first information is used to instruct the UL signal to be transmitted on the SBFD symbol, or to instruct the UL signal to be transmitted on a non-SBFD symbol, the terminal configures the N symbols following the DL symbol or SBFD symbol via the third parameter. The terminal determines that the N symbols following the DL symbol or SBFD symbol are invalid symbols.

[0122] In some embodiments, the third parameter can be tdd-UL-DL-ConfigurationCommon and / or tdd-UL-DL-ConfigurationDedicated. That is, when the terminal determines that the first information is used to instruct the UL signal to be transmitted on an SBFD symbol, or to instruct the UL signal to be transmitted on a non-SBFD symbol, it configures the N symbols following the DL symbol or SBFD symbol using tdd-UL-DL-ConfigurationCommon and / or tdd-UL-DL-ConfigurationDedicated. The terminal determines that the N symbols following the DL symbol or SBFD symbol are invalid symbols.

[0123] In some embodiments, the first preset condition may include the target symbol being configured as a DL symbol in the first cell and being a non-SBFD symbol in the CA scenario, and the target symbol being an invalid symbol in the second cell, wherein the serving cell includes the first cell and the second cell, and the second cell is a serving cell that is different from the first cell.

[0124] In some embodiments, for a CA scenario, when the terminal determines that the first information is used to indicate that the UL signal is transmitted on an SBFD symbol and to indicate that the UL signal is transmitted on a non-SBFD symbol, the terminal determines that the target symbol is a DL symbol in the first cell and that the target symbol is a non-SBFD symbol in the CA scenario. The terminal may determine that the target symbol is an invalid symbol in the second cell of the serving cell.

[0125] It is understandable that the first community can be the reference community, and the second community can be a community other than the reference community in the service community.

[0126] It is clear that this example can be used as a reference. Figure 3 In a CA (Carrier-Oriented) scenario, CC can also be referred to as a cell. When different cells are not allowed to transmit and receive simultaneously, assume the first cell is configured with a DL (Deep Transmission) symbol, and this symbol is not an SBFD (Short-Stopped Flow) symbol. This means other cells are also configured with DL symbols. Since different cells are not allowed to transmit and receive simultaneously, the target symbol is invalid for other cells. That is, other cells are not allowed to transmit UL (Upper-Level) signals on the target symbol. Of course, these other cells can be understood as the second cell mentioned above.

[0127] In some embodiments, the terminal can configure the target symbol as a DL symbol in the first cell via a third parameter. That is, in a CA scenario, when the terminal determines that the first information is used to indicate that the UL signal is transmitted on an SBFD symbol and to indicate that the UL signal is transmitted on a non-SBFD symbol, the target symbol is configured as a DL symbol in the first cell via the third parameter, and the target symbol is a non-SBFD symbol in the CA scenario. The terminal can determine that the target symbol is an invalid symbol in the second cell within the serving cell.

[0128] In some embodiments, the third parameter can be tdd-UL-DL-ConfigurationCommon and / or tdd-UL-DL-ConfigurationDedicated. That is, in a CA scenario, when the terminal determines that the first information is used to indicate that the UL signal is transmitted on an SBFD symbol and to indicate that the UL signal is transmitted on a non-SBFD symbol, the target symbol is configured as a DL symbol in the first cell using tdd-UL-DL-ConfigurationCommon and / or tdd-UL-DL-ConfigurationDedicated, and the target symbol is a non-SBFD symbol in the CA scenario. The terminal can determine that the target symbol is an invalid symbol in the second cell within the serving cell.

[0129] In some embodiments, the serving cell may be a serving cell configured with directionalCollisionHandling-r16=enabled. Of course, in all embodiments of this disclosure, the serving cell may be a serving cell configured with directionalCollisionHandling-r16=enabled.

[0130] In some embodiments, the first preset condition may include the target symbol being configured as any one of DL symbol, UL symbol, and F symbol in the first cell, the target symbol being configured as UL symbol or F symbol in the second cell, and the target symbol being a valid symbol in the second cell.

[0131] For example, in a CA scenario, when the terminal determines that the first information is used to indicate that the UL signal is transmitted on an SBFD symbol and to indicate that the UL signal is transmitted on a non-SBFD symbol, the terminal determines that the target symbol is configured as any one of the DL symbol, UL symbol, and F symbol in the first cell, and determines that the target symbol is configured as a UL symbol or F symbol in the second cell. The terminal can then determine that the target symbol is a valid symbol in the second cell of the serving cell.

[0132] In some embodiments, the terminal can configure the target symbol in the first cell as any one of a DL symbol, a UL symbol, and an F symbol using a third parameter. That is, in a CA scenario, when the terminal determines that the first information is used to indicate that the UL signal is transmitted on an SBFD symbol, and to indicate that the UL signal is transmitted on a non-SBFD symbol, the target symbol in the first cell is configured as any one of a DL symbol, a UL symbol, and an F symbol using the third parameter, and the terminal determines that the target symbol is configured as a UL symbol or an F symbol in the second cell. The terminal can then determine that the target symbol is a valid symbol in the second cell within the serving cell.

[0133] In some embodiments, the third parameter can be tdd-UL-DL-ConfigurationCommon and / or tdd-UL-DL-ConfigurationDedicated. That is, in a CA scenario, when the terminal determines that the first information is used to instruct the UL signal to be transmitted on an SBFD symbol, and to instruct the UL signal to be transmitted on a non-SBFD symbol, the target symbol is configured as any one of a DL symbol, UL symbol, and F symbol in the first cell via tdd-UL-DL-ConfigurationCommon and / or tdd-UL-DL-ConfigurationDedicated, and determines that the target symbol is configured as a UL symbol or an F symbol in the second cell. The terminal can then determine that the target symbol is a valid symbol in the second cell within the serving cell.

[0134] In other words, in this example, regardless of the symbol type configured in the first cell via tdd-UL-DL-ConfigurationCommon and / or tdd-UL-DL-ConfigurationDedicated, it does not affect whether the target symbol in the second cell of the serving cell with directionalCollisionHandling-r16=enabled is an invalid symbol. In some cases, it can be determined that regardless of the symbol type configured in the first cell via tdd-UL-DL-ConfigurationCommon and / or tdd-UL-DL-ConfigurationDedicated, if the target symbol is configured as a UL symbol or an F symbol in the second cell, then the target symbols in the second cell of the serving cell with directionalCollisionHandling-r16=enabled are all valid symbols.

[0135] This disclosure provides a variety of preset conditions to determine possible invalid symbols based on the corresponding preset conditions. This ensures that uplink signals can be transmitted on allowed symbols, thereby improving uplink communication efficiency.

[0136] In the communication method provided in this embodiment, the first information is used to indicate that the UL signal is transmitted on the SBFD symbol; the preset conditions include at least one of the following: non-SBFD symbols are invalid symbols; the symbol where the SSB is located is a DL symbol, an F symbol, or an SBFD symbol, and the symbol where the SSB is located is invalid; the symbol where the SSB is located is an SBFD symbol, the terminal is configured to perform measurement on the SSB, and the symbol where the SSB is located is invalid; the symbol where the Type0-PDCCH is located is a DL symbol, an F symbol, or an SBFD symbol, and the symbol where the Type0-PDCCH is located is invalid; the symbol where the Type0-PDCCH is located is an SBFD symbol, the terminal is configured to receive DCI on the Type0-PDCCH, and the symbol where the Type0-PDCCH is located is invalid; N symbols following the DL symbol or SBFD symbol are treated as invalid symbols, where N is an integer greater than or equal to 0; the target symbol is configured as a non-SBFD symbol in the CA scenario, and the target symbol is invalid in the second cell; the target symbol is configured as an SBFD symbol in the CA scenario, and the target symbol is configured as a DL symbol in the second cell, and the target symbol is invalid in the second cell.

[0137] In some embodiments, when the first information is used to indicate that a UL signal is transmitted on an SBFD symbol, the terminal may determine an invalid symbol based on any one or more of the following preset conditions. Wherein, when the first information is used to indicate that a UL signal is transmitted on an SBFD symbol, the preset condition may be referred to as the second preset condition.

[0138] For example, the terminal receives first information. This first information is used to instruct the UL signal to be transmitted on the SBFD symbol. The terminal can then determine an invalid symbol based on any one or more of the following second preset conditions.

[0139] For example, the terminal determines the first information used to indicate the transmission of the UL signal on the SBFD symbol according to predefined rules. The terminal can then determine an invalid symbol based on any one or more of the following second preset conditions.

[0140] In some embodiments, the second preset condition may include non-SBFD symbols as invalid symbols.

[0141] In some embodiments, when the terminal determines that the first information is used to indicate that the UL signal is transmitted on the SBFD symbol, it can identify a non-SBFD symbol and determine that the non-SBFD symbol is an invalid symbol.

[0142] In some embodiments, the terminal can configure a non-SBFD symbol via a third parameter. That is, when the terminal determines that the first information is used to indicate that the UL signal is transmitted on an SBFD symbol, it configures a non-SBFD symbol via the third parameter and determines that the non-SBFD symbol is an invalid symbol.

[0143] In some embodiments, the third parameter can be tdd-UL-DL-ConfigurationCommon and / or tdd-UL-DL-ConfigurationDedicated. That is, when the terminal determines that the first information is used to indicate that the UL signal is transmitted on the SBFD symbol, it configures the non-SBFD symbol through tdd-UL-DL-ConfigurationCommon and / or tdd-UL-DL-ConfigurationDedicated, and determines that the non-SBFD symbol is an invalid symbol.

[0144] In some embodiments, the second preset condition may include the symbol containing the SSB being a DL symbol, an F symbol, or an SBFD symbol, and the symbol containing the SSB being an invalid symbol. The non-SBFD symbol includes any one or more of the UL symbol, DL symbol, and F symbol.

[0145] In some embodiments, the second preset condition may include the symbol where the SSB is located being the SBFD symbol, the terminal being configured to perform measurements on the SSB, and the symbol where the SSB is located being an invalid symbol.

[0146] In some embodiments, the second preset condition may include the symbol where Type0-PDCCH is located being a DL symbol, an F symbol, or an SBFD symbol, and the symbol where Type0-PDCCH is located being an invalid symbol.

[0147] In some embodiments, the second preset condition may include the symbol where the Type0-PDCCH is located being an SBFD symbol, the terminal being configured to receive DCI on the Type0-PDCCH, and the symbol where the Type0-PDCCH is located being an invalid symbol.

[0148] In some embodiments, the second preset condition may include N symbols following the DL symbol or SBFD symbol, where N symbols are invalid symbols. Here, N is an integer greater than or equal to 0.

[0149] It is understood that some of the optional implementation methods of the above-mentioned second preset conditions can be referred to the description of the corresponding embodiments and their related embodiments in the first preset conditions, and will not be repeated here.

[0150] In some embodiments, the second preset condition may include the target symbol being configured as a non-SBFD symbol in a CA scenario, and the target symbol being an invalid symbol in a second cell.

[0151] In some embodiments, in a CA scenario, if the terminal determines that the first information is used to indicate that the UL signal is transmitted on an SBFD symbol, it determines that the target symbol is a non-SBFD symbol. Therefore, the terminal can determine that the target symbol in the second cell of the serving cell is an invalid symbol.

[0152] In some embodiments, the terminal can configure the target symbol as a non-SBFD symbol via a third parameter. That is, in a CA scenario, when the terminal determines that the first information is used to indicate that the UL signal is transmitted on an SBFD symbol, it configures the target symbol as a non-SBFD symbol via the third parameter. Furthermore, the terminal can determine that the target symbol in the second cell of the serving cell is an invalid symbol.

[0153] In some embodiments, the third parameter can be tdd-UL-DL-ConfigurationCommon and / or tdd-UL-DL-ConfigurationDedicated. That is, in a CA scenario, when the terminal determines that the first information is used to instruct the UL signal to be transmitted on an SBFD symbol, it configures the target symbol as a non-SBFD symbol using tdd-UL-DL-ConfigurationCommon and / or tdd-UL-DL-ConfigurationDedicated. Furthermore, the terminal can determine that the target symbol in the second cell of the serving cell is an invalid symbol.

[0154] In some embodiments, the second preset condition may include the target symbol being configured as an SBFD symbol in a CA scenario and the target symbol being configured as a DL symbol in a second cell, wherein the target symbol is an invalid symbol in the second cell.

[0155] In some embodiments, in a CA scenario, when the terminal determines that the first information is used to indicate that the UL signal is transmitted on the SBFD symbol, it determines that the target symbol is an SBFD symbol. Furthermore, since the target symbol is configured as a DL symbol in the second cell, the terminal can determine that the target symbol in the second cell of the serving cell is an invalid symbol.

[0156] In some embodiments, the terminal can configure the target symbol as an SBFD symbol via a third parameter. That is, in a CA scenario, when the terminal determines that the first information is used to indicate that the UL signal is transmitted on an SBFD symbol, it configures the target symbol as an SBFD symbol via the third parameter, and the target symbol is configured as a DL symbol in the second cell. Therefore, the terminal can determine that the target symbol in the second cell of the serving cell is an invalid symbol.

[0157] In some embodiments, the third parameter can be tdd-UL-DL-ConfigurationCommon and / or tdd-UL-DL-ConfigurationDedicated. That is, in a CA scenario, when the terminal determines that the first information is used to instruct the UL signal to be transmitted on an SBFD symbol, it configures the target symbol as an SBFD symbol using tdd-UL-DL-ConfigurationCommon and / or tdd-UL-DL-ConfigurationDedicated, and the target symbol is configured as a DL symbol in the second cell. Therefore, the terminal can determine that the target symbol in the second cell of the serving cell is an invalid symbol.

[0158] Of course, in some embodiments, for CA scenarios, when the terminal determines that the first information is used to instruct the UL signal to be transmitted on the SBFD symbol, it determines that the target symbol is configured as an SBFD symbol by tdd-UL-DL-ConfigurationCommon and / or tdd-UL-DL-ConfigurationDedicated. Furthermore, the target symbol is configured as a UL symbol or an F symbol in the second cell, thus the terminal can determine that the target symbol is a valid symbol in the second cell among the serving cells with directionalCollisionHandling-r16=enabled.

[0159] This disclosure provides a variety of preset conditions to determine possible invalid symbols based on the corresponding preset conditions. This ensures that uplink signals can be transmitted on allowed symbols, thereby improving uplink communication efficiency.

[0168] In some embodiments, the third parameter can be an information element other than tdd-UL-DL-ConfigurationCommon and tdd-UL-DL-ConfigurationDedicated. That is, when the terminal determines that the first information is used to indicate that the UL signal is transmitted on a non-SBFD symbol, it configures the SBFD symbol through other information elements and determines that the SBFD symbol is an invalid symbol.

[0169] In some embodiments, when the terminal determines that the first information is used to indicate that the UL signal is transmitted on a non-SBFD symbol, it can determine the DL symbol and determine that the DL symbol is an invalid symbol.

[0172] In some embodiments, the third preset condition may include N symbols following the DL symbol or SBFD symbol, where N symbols are invalid symbols, and N is an integer greater than or equal to 0.

[0173] It is understood that some of the optional implementation methods of the third preset condition mentioned above can be referred to the descriptions of the corresponding embodiments and their associated embodiments in the first preset condition, and the descriptions of the corresponding embodiments and their associated embodiments in the second preset condition, which will not be repeated here.

[0174] In some embodiments, the third preset condition may include the target symbol being configured as an SBFD symbol in a CA scenario, and the target symbol being an invalid symbol in the second cell.

[0175] In some embodiments, in a CA scenario, if the terminal determines that the first information is used to indicate that the UL signal is transmitted on a non-SBFD symbol, the terminal determines that the target symbol is an SBFD symbol. Furthermore, the terminal can determine that the target symbol in the second cell of the serving cell is an invalid symbol.

Furthermore, if the target symbol is configured as a DL symbol in the second cell, the terminal can then determine that the target symbol in the second cell of the serving cell is an invalid symbol. It is clear that in this case, different cells are not allowed to transmit and receive signals simultaneously.

[0180] In some embodiments, the terminal can configure the target symbol as a non-SBFD symbol via a third parameter. That is, in a CA scenario, when the terminal determines that the first information is used to instruct the UL signal to be transmitted on a non-SBFD symbol, it configures the target symbol as a non-SBFD symbol via the third parameter, and the target symbol is configured as a DL symbol in the second cell. Furthermore, the terminal can determine that the target symbol in the second cell of the serving cell is an invalid symbol.

[0181] In some embodiments, the third parameter can be tdd-UL-DL-ConfigurationCommon and / or tdd-UL-DL-ConfigurationDedicated. That is, in a CA scenario, when the terminal determines that the first information is used to indicate that the UL signal is transmitted on a non-SBFD symbol, it configures the target symbol as a non-SBFD symbol using tdd-UL-DL-ConfigurationCommon and / or tdd-UL-DL-ConfigurationDedicated, and the target symbol is configured as a DL symbol in the second cell. Therefore, the terminal can determine that the target symbol in the second cell of the serving cell is an invalid symbol.

[0182] Of course, in some embodiments, for CA scenarios, when the terminal determines that the first information is used to indicate that the UL signal is transmitted on a non-SBFD symbol, it determines that the target symbol is configured as a non-SBFD symbol by tdd-UL-DL-ConfigurationCommon and / or tdd-UL-DL-ConfigurationDedicated. Furthermore, the target symbol is configured as a UL symbol or an F symbol in the second cell, thus the terminal can determine that the target symbol is a valid symbol in the second cell among the serving cells with directionalCollisionHandling-r16=enabled.

[0183] This disclosure provides a variety of preset conditions to determine possible invalid symbols based on the corresponding preset conditions. This ensures that uplink signals can be transmitted on allowed symbols, thereby improving uplink communication efficiency.

[0184] In the communication method provided in this disclosure, the preset conditions include N symbols following the DL symbol or SBFD symbol, where N symbols are invalid symbols. N includes N1 and / or N2. The N symbols are determined based on at least one of the following methods: determining N1 consecutive symbols following the DL symbol; determining N2 consecutive symbols following the SBFD symbol. In some embodiments, the preset conditions may include N symbols following the LD symbol or SBFD symbol, where these N symbols are invalid symbols. N may include N1 and / or N2.

[0185] In some embodiments, N1 consecutive symbols following the DL symbol can be identified as invalid symbols.

[0186] In some embodiments, the N1 consecutive symbols following the DL symbol can be determined in several ways. For example, the N1 consecutive symbols following the DL symbol can be determined using the fourth parameter, numberOfInvalidSymbolsForDL-UL-Switching.

[0187] In some embodiments, N2 consecutive symbols following the SBFD symbol can be identified as invalid symbols.

[0188] In some embodiments, the N2 consecutive symbols following the SBFD symbol can be determined in several ways. For example, the fourth parameter, numberOfInvalidSymbolsForDL-UL-Switching, can be used to determine the N2 consecutive symbols following the SBFD symbol. Alternatively, the fifth parameter, numberOfInvalidSymbolsForDL-UL-Switching-SBFD, can be used to determine the N2 consecutive symbols following the SBFD symbol.

[0189] In some embodiments, the SCS corresponding to the symbol length can be determined by the referenceSubcarrierSpacing configured in tdd-UL-DL-ConfigurationCommon.

[0190] This disclosure provides several methods for identifying invalid symbols. This ensures that uplink signals can be transmitted on allowed symbols, improving uplink communication efficiency.

[0191] In the communication method provided in the embodiments of this disclosure, N1 and / or N2 are determined based on the same parameters; and / or, N1 and / or N2 are determined based on different parameters.

[0192] In some embodiments, N1 and / or N2 can be determined based on the same parameter. The same parameter can be, for example, a fourth parameter, namely numberOfInvalidSymbolsForDL-UL-Switching.

[0193] In some embodiments, N1 consecutive symbols following the DL symbol are determined based on numberOfInvalidSymbolsForDL-UL-Switching, and these N1 symbols are invalid symbols. Additionally, N2 consecutive symbols following the SBFD symbol are determined based on numberOfInvalidSymbolsForDL-UL-Switching, and these N2 symbols are invalid symbols.

[0194] In some embodiments, N1 and / or N2 can be determined based on different parameters. For example, N1 can be determined by the fourth parameter, numberOfInvalidSymbolsForDL-UL-Switching, and / or N2 can be determined by the fifth parameter, numberOfInvalidSymbolsForDL-UL-Switching-SBFD.

[0195] This disclosure provides several methods for identifying invalid symbols. This ensures that uplink signals can be transmitted on allowed symbols, improving uplink communication efficiency.

[0196] In the communication method provided in this embodiment, N1 and / or N2 can be configured to 0; and / or, N2 and N1 can be the same or different.

[0197] In some embodiments, the N1 consecutive symbols following the DL symbol can be configured to be 0. This means that the next symbol after the DL symbol is not an invalid symbol, or that the next symbol after the DL symbol can be considered a valid symbol.

[0198] In some embodiments, the N2 consecutive symbols following the SBFD symbol can be configured to be 0. That is, it means that the next symbol after the SBFD symbol is not an invalid symbol, or it can be considered that the next symbol after the SBFD symbol is a valid symbol.

[0199] In some embodiments, the N1 consecutive symbols following the DL symbol can be configured to be 0, and the N2 consecutive symbols following the SBFD symbol can be configured to be 0. This means that the next symbol after the DL symbol is not an invalid symbol, or that the next symbol after the DL symbol can be considered a valid symbol. Similarly, this means that the next symbol after the SBFD symbol is not an invalid symbol, or that the next symbol after the SBFD symbol can be considered a valid symbol.

[0200] In some embodiments, the number of consecutive N1 symbols following a DL symbol is the same as the number of consecutive N2 symbols following an SBFD symbol.

[0201] For example, it can be determined that numberOfInvalidSymbolsForDL-UL-Switching-SBFD is the same as the numberOfInvalidSymbolsForDL-UL-Switching configured.

[0202] Alternatively, without configuring numberOfInvalidSymbolsForDL-UL-Switching-SBFD, the N2 consecutive symbols following the SBFD symbol can be determined by numberOfInvalidSymbolsForDL-UL-Switching, that is, N1 configured in numberOfInvalidSymbolsForDL-UL-Switching is used as N2.

[0203] This disclosure provides one possible scenario for the number of persistent symbols following DL symbols and / or SBFD symbols, thereby treating the aforementioned persistent symbols as invalid symbols. This ensures that uplink signals can be transmitted on permitted symbols, improving uplink communication efficiency.

[0204] In the communication method provided in this embodiment, the preset conditions may further include at least one of the following: the DL symbol is an invalid symbol; the symbol where the SSB is located is an invalid symbol; the symbol where the Type0-PDCCH is located is an invalid symbol; the N3 symbols after the DL symbol are invalid symbols, where N3 is an integer greater than or equal to 1; the target symbol is configured as the DL symbol in the first cell and is an invalid symbol in the second cell.

[0205] In some embodiments, the preset conditions may also include DL symbols being invalid symbols.

[0207] In some embodiments, the DL symbol can be configured via a third parameter. That is, the third parameter configures the DL symbol, which is an invalid symbol.

[0208] In some embodiments, the third parameter can be tdd-UL-DL-ConfigurationCommon and / or tdd-UL-DL-ConfigurationDedicated. That is, tdd-UL-DL-ConfigurationCommon and / or tdd-UL-DL-ConfigurationDedicated configure DL symbols, which are invalid symbols.

[0209] In some embodiments, the preset conditions may also include that the symbol containing the SSB is an invalid symbol.

[0210] In some embodiments, regardless of which situation the first information indicates, i.e., the first preset condition, the second preset condition, and / or the third preset condition, may also include: determining the symbol where the SSB is located, wherein the symbol where the SSB is located is an invalid symbol.

[0211] In some embodiments, the symbol containing the SSB can be configured via the first parameter. That is, the first parameter configures the symbol containing the SSB, and the symbol containing the SSB is an invalid symbol.

[0212] In some embodiments, the first parameter can be ssb-PositionsInBurst. That is, ssb-PositionsInBurst configures the symbol where the SSB is located, and the symbol where the SSB is located is an invalid symbol.

[0213] In some embodiments, the preset conditions may also include that the symbol containing Type0-PDCCH is an invalid symbol.

[0214] In some embodiments, regardless of which situation the first information indicates, i.e., the first preset condition, the second preset condition, and / or the third preset condition may also include: determining the symbol where the Type0-PDCCH is located, wherein the symbol where the Type0-PDCCH is located is an invalid symbol.

[0215] In some embodiments, the symbol containing Type0-PDCCH can be configured via a second parameter. That is, the second parameter configures the symbol containing Type0-PDCCH, and the symbol containing Type0-PDCCH is an invalid symbol.

[0216] In some embodiments, the second parameter can be PDCCH-ConfigSIB1. That is, PDCCH-ConfigSIB1 configures the symbol where Type0-PDCCH is located, and the symbol where Type0-PDCCH is located is an invalid symbol.

[0217] In some embodiments, the preset conditions may further include N3 symbols after configuring DL symbols, and treating N3 symbols as invalid symbols, where N3 is an integer greater than or equal to 1.

[0218] In some embodiments, regardless of which condition the first information indicates, i.e., the first preset condition, the second preset condition, and / or the third preset condition may further include: determining N3 symbols after configuring the DL symbol. Here, N3 is an integer greater than or equal to 1. The terminal determines that the N3 symbols after the DL symbol are invalid symbols. The SCS corresponding to the symbol length can be determined through the referenceSubcarrierSpacing configured in tdd-UL-DL-ConfigurationCommon.

[0219] In some embodiments, the N3 symbols following the DL symbol can be configured via a third parameter.

[0220] In some embodiments, the third parameter can be tdd-UL-DL-ConfigurationCommon and / or tdd-UL-DL-ConfigurationDedicated. It will be understood that in all embodiments of this disclosure, the third parameter can be tdd-UL-DL-ConfigurationCommon and / or tdd-UL-DL-ConfigurationDedicated.

[0221] In some embodiments, the preset conditions may further include the target symbol being configured as a DL symbol in the first cell and the target symbol being an invalid symbol in the second cell.

[0222] In some embodiments, regardless of which situation the first information indicates, i.e., the first preset condition, the second preset condition, and / or the third preset condition may further include: in a CA scenario, determining that the target symbol is a DL symbol in the first cell. Then, the terminal can determine that the target symbol is an invalid symbol in the second cell of the serving cells. Here, the first cell is a reference cell, and the second cell is another cell in the serving cells besides the reference cell.

[0223] In some embodiments, the target symbol can be configured as a DL symbol in the first cell via a third parameter.

[0224] This disclosure provides a variety of preset conditions to determine possible invalid symbols based on the corresponding preset conditions. This ensures that uplink signals can be transmitted on allowed symbols, thereby improving uplink communication efficiency.

[0225] In the communication method provided in this embodiment, on the target symbol, the first cell is the cell with the smallest cell index in the first cell group. The third cell in the first cell group is the active serving cell, wherein the third cell is any cell in the first cell group, and the third cell satisfies at least one of the following conditions: the symbol class corresponding to the third cell is configured as F symbol, and the terminal in the third cell is configured to transmit one or more of SRS, physical uplink control channel (PUCCH), PUSCH, and physical random access channel (PRACH); the symbol corresponding to the third cell is configured as F symbol, and the terminal in the third cell is configured to receive one or more of PDCCH, PDSCH, and CSI-RS; the symbol class corresponding to the third cell is configured as DL symbol or UL symbol.

[0226] In some embodiments, the first cell may also be referred to as the reference cell.

[0227] In some embodiments, the first cell group includes multiple cells, which are active serving cells. The first cell may be the cell with the smallest index in the first cell group.

[0228] In some embodiments, any cell in the first cell group may be referred to as the third cell. The third cell is an active serving cell and satisfies at least one of the following conditions: the symbol class corresponding to the third cell is configured as a DL symbol or a UL symbol; the symbol class corresponding to the third cell is configured as an F symbol, and the terminal in the third cell is configured to transmit one or more of SRS, PUCCH, PUSCH, and PRACH; the symbol class corresponding to the third cell is configured as an F symbol, and the terminal in the third cell is configured to receive one or more of PDCCH, PDSCH, and CSI-RS.

[0229] In some embodiments, the second cell is a serving cell other than the first cell, and the second cell satisfies at least one of the following conditions: the second cell is an active serving cell; the second cell is configured to handle conflicts arising between the second cell and the first cell.

[0230] It is worth noting that in the embodiments of this disclosure, there is no direct relationship between the second cell and the first cell group. For example, a cell in the first cell group other than the first cell may or may not be the second cell. For example, if a cell in the first cell group other than the first cell is configured with directionalCollisionHandling-r16=enabled, it can be considered a second cell. Furthermore, a second cell does not necessarily belong to the first cell group. For example, if other serving cells outside the first cell group are configured with directionalCollisionHandling-r16=enabled, they can also be considered second cells.

[0231] In some embodiments, on the target symbol, the first cell can be a reference cell, which is the cell with the smallest cell index in the first cell group. Any cell in the first cell group can be an active serving cell; that is, any cell in the first cell group is an active serving cell. Furthermore, the symbol class corresponding to any cell in the first cell group is configured as F symbol, and the terminal in that cell is configured to send one or more of SRS, PUCCH, PUSCH, and PRACH. It is understood that the target symbol can be an invalid symbol or a valid symbol.

[0232] For example, the first cell is the reference cell and the cell with the smallest index in the first cell group. It is clear that since any cell in the first cell group is an active serving cell, the first cell is also an active serving cell. For the first cell group, if any cell in the first cell group has its corresponding symbol class configured as F, the terminal in that cell is configured to send one or more of SRS, PUCCH, PUSCH, and PRACH.

[0233] In some embodiments, on the target symbol, the first cell may be a reference cell, which is the cell with the smallest cell index in the first cell group. Any cell in the first cell group can be an active serving cell; that is, any cell in the first cell group is an active serving cell. Furthermore, the symbol class corresponding to any cell in the first cell group is configured as F symbol, and the terminal is configured to receive one or more of PDCCH, PDSCH, and CSI-RS in that cell.

[0234] For example, the first cell is the reference cell and the cell with the smallest index in the first cell group. It is clear that since any cell in the first cell group is an active serving cell, the first cell is also an active serving cell. For the first cell group, if any cell in the first cell group has its corresponding symbol class configured as F, the terminal in that cell is configured to receive one or more of PDCCH, PDSCH, and CSI-RS.

[0235] In some embodiments, on the target symbol, the first cell can be a reference cell, which is the cell with the smallest cell index in the first cell group. Any cell in the first cell group can be an active serving cell; that is, any cell in the first cell group is an active serving cell. Furthermore, the symbol category corresponding to any cell in the first cell group is configured as either a UL symbol or a DL symbol.

[0236] For example, the first cell is the reference cell and the cell with the smallest index in the first cell group. It's clear that since any cell in the first cell group is an active serving cell, the first cell is also an active serving cell. For the first cell group, the symbol class corresponding to any cell in this group is configured as a UL symbol using tdd-UL-DL-ConfigurationCommon and / or tdd-UL-DL-ConfigurationDedicated. Alternatively, the symbol class corresponding to any cell in this first cell group is configured as a DL symbol using tdd-UL-DL-ConfigurationCommon and / or tdd-UL-DL-ConfigurationDedicated.

[0237] In some embodiments, under CA scenarios, the first cell is a reference cell and can be selected in the following ways: If the terminal does not support simultaneous transmission and reception between any two inter-band cells: the first cell is the cell with the smallest index in the first cell group. Alternatively, if the terminal supports simultaneous transmission and reception between any two inter-band cells: one first cell can be selected for each band. For example, a first cell group is determined for each band, and the first cell in each first cell group is determined. The first cell in the first cell group of each band can be the cell with the smallest index in that first cell group.

[0238] This disclosure provides a first cell satisfaction condition to identify potentially invalid symbols in CA scenarios. This ensures that uplink signals can be transmitted on allowed symbols, improving uplink communication efficiency.

[0239] In the communication method provided in this embodiment, on the target symbol, the second cell is a cell other than the first cell among the serving cells, and satisfies at least one of the following conditions: the second cell is an active serving cell; the second cell is configured to handle conflicts arising between the second cell and the first cell.

[0240] In some embodiments, on the target symbol, the second cell is a cell other than the first cell among the serving cells.

[0241] It is clear that since the second cell is not directly related to the first cell group, the symbol corresponding to the second cell does not need to meet the conditions of the first cell group. For example, it does not need to be configured as a DL symbol or a UL symbol, or it does not need to be configured as an F symbol and transmit one or more of SRS, PUCCH, PUSCH, and PRACH, or it can be configured as an F symbol and receive one or more of PDCCH, PDSCH, and CSI-RS.

[0242] In some embodiments, the second cell is the active serving cell.

[0243] In some embodiments, the second cell is configured to handle conflicts arising between the second cell and the first cell. For example, the second cell is configured with directionalCollisionHandling-r16=enabled. This allows the second cell to handle conflicts when they occur between the first and second cells, preventing the conflicts from affecting its communication.

[0244] In some embodiments, the second cell is an active serving cell, and the second cell is configured to handle conflicts arising between the second cell and the first cell.

[0245] It is understood that the description of the first cell group can be referred to the above-mentioned first cell related embodiments and their associated embodiments, and will not be repeated here.

[0246] This disclosure provides a second cell satisfaction condition to identify potentially invalid symbols in CA scenarios. This ensures that uplink signals can be transmitted on allowed symbols, improving uplink communication efficiency.

[0247] In the communication method provided in the embodiments of this disclosure Figure 7 This is a flowchart illustrating another communication method according to an exemplary embodiment. For example... Figure 7 As shown, the method may also include the following steps:

[0248] In step S21, the second information is received.

[0249] In some embodiments, the terminal may also receive second information. This second information is used to instruct the terminal to send a UL signal.

[0250] For example, the terminal can also receive a second message sent by the network device, which instructs the terminal to send a UL signal.

[0251] If the terminal receives RRC and / or DCI, it may instruct the terminal to send PUSCH. For example, it may instruct the terminal to send PUSCH repetition type B.

[0252] In some embodiments, determining the invalid symbol in the symbol containing the UL signal based on the first information in step S12 may further include the following steps:

[0253] In step S22, based on the first information and the second information, invalid symbols in the symbols containing the UL signal are determined.

[0254] In some embodiments, the terminal may determine the invalid symbol in the symbol containing the UL signal based on the first information determined in S11 and the second information received in S21.

[0255] For example, the terminal determines that the first information indicates that the UL signal is transmitted on at least one of the SBFD symbols and non-SBFD symbols, and determines the invalid symbol in the symbol where the UL signal is located based on the corresponding preset rules and the partial parameters configured in the second information for transmitting the UL signal.

[0256] This disclosure identifies potentially invalid symbols by indicating whether data transmission is permitted on at least one of SBFD symbols and non-SBFD symbols. This ensures that uplink signals can be transmitted on permitted symbols, improving uplink communication efficiency.

[0257] In the communication method provided in this embodiment, determining the first information in step S11 may include receiving the first information.

[0258] In some embodiments, the terminal may receive first information sent by the network device to determine that the first information can be used to instruct the UL signal to be sent on at least one of the SBFD symbol and non-SBFD symbol.

[0259] For example, the terminal receives first information sent by the network device, which indicates that UL is allowed to send on both SBFD symbols and non-SBFD symbols.

[0260] For example, the terminal receives first information sent by the network device, which indicates that UL is permitted to send on the SBFD symbol.

[0261] For example, the terminal receives first information sent by the network device, which indicates that UL is allowed to transmit on a non-SBFD symbol.

[0262] This disclosure identifies potentially invalid symbols by indicating whether data transmission is permitted on at least one of SBFD symbols and non-SBFD symbols. This ensures that uplink signals can be transmitted on permitted symbols, improving uplink communication efficiency.

[0263] Based on the same concept, embodiments of this disclosure also provide communication methods performed by network devices.

[0264] Figure 8 This is a flowchart illustrating yet another communication method according to an exemplary embodiment, such as... Figure 8 As shown, the method is executed by a network device and may include the following steps:

[0265] In step S31, the first message is sent.

[0266] In some embodiments, the network device may send first information. This first information may be used to instruct the terminal to send a UL signal on at least one of the SBFD symbol and non-SBFD symbols.

[0267] For example, a network device sends first information to a terminal so that the terminal can receive the first information sent by the network device and determine, based on the first information, to send a UL signal on SBFD symbols and / or non-SBFD symbols.

[0268] In some embodiments, the symbol containing the UL signal includes an invalid symbol. This invalid symbol can be understood as a symbol on which the terminal is not permitted to send the UL signal.

[0269] For example, if the first information indicates that the terminal is allowed to send a UL signal on an SBFD symbol, the symbol where the UL signal is located may include the SBFD symbol.

[0270] For example, if the first information indicates that the terminal is allowed to send UL signals on non-SBFD symbols, the symbol containing the UL signal may include a non-SBFD symbol.

[0271] For example, if the first information indicates that the terminal is allowed to send UL signals on SBFD symbols and non-SBFD symbols, the symbols on which the UL signals are located may include SBFD symbols and / or non-SBFD symbols.

[0272] Of course, in some embodiments, the method may also include the following steps:

[0273] In step S32, the UL signal is received.

[0274] In some embodiments, the network device may receive a UL signal sent by the terminal on a valid symbol.

[0275] This disclosure identifies potentially invalid symbols by indicating whether data transmission is permitted on at least one of SBFD symbols and non-SBFD symbols. This ensures that uplink signals can be transmitted on permitted symbols, improving uplink communication efficiency.

[0276] In the communication method provided in this embodiment, invalid symbols are determined based on the following method: invalid symbols are determined based on preset conditions corresponding to the first information.

[0277] In some embodiments, invalid symbols may be determined based on preset conditions corresponding to the first information.

Valid symbols; the symbol containing Type0-PDCCH is an SBFD symbol, and the terminal is configured to receive DCI on Type0-PDCCH, so the symbol containing Type0-PDCCH is an invalid symbol; the N symbols following the DL symbol or SBFD symbol are invalid symbols, where N is an integer greater than or equal to 0; the target symbol is configured as a DL symbol in the first cell, and the target symbol is a non-SBFD symbol in the carrier aggregation (CA) scenario, and the target symbol is an invalid symbol in the second cell, where the serving cell includes the first cell and the second cell, and the second cell is a serving cell different from the first cell; the target symbol is configured as any one of DL symbol, UL symbol, and F symbol in the first cell, and the target symbol is configured as a UL symbol or F symbol in the second cell, so the target symbol is a valid symbol in the second cell.
