[0048] Figure 1 is a schematic diagram of the architecture of a communication system according to an embodiment of the present disclosure. As shown in Figure 1, the communication system 100 may include a terminal 101 and a network device 102. The network device 102 may include at least one of an access network device and a core network device.

[0049] In some embodiments, the terminal 101 includes, for example, a mobile phone, a wearable device, an Internet of Things device, a car with communication function, a smart car, a tablet computer, a computer with wireless transceiver function, a virtual reality (VR) terminal device, an augmented reality (AR) terminal device, a wireless terminal device in industrial control, a wireless terminal device in self-driving, a wireless terminal device in remote medical surgery, a wireless terminal device in a smart grid, a wireless terminal device in transportation safety, a wireless terminal device in a smart city, and at least one of a wireless terminal device in a smart home, but is not limited thereto.

The access network device may include an evolved NodeB (eNB) in a 5G communication system, a next generation evolved NodeB (ng-eNB), a next generation NodeB (gNB), a node B (NB), a home node B (HNB), a home evolved nodeB (HeNB), a wireless backhaul device, a radio network controller (RNC), a base station controller (BSC), a base transceiver station (BTS), a base band unit (BBU), a mobile switching center, a base station in a 6G communication system, an open base station (Open RAN), a cloud base station (Cloud RAN), a base station in other communication systems, and at least one of an access node in a WiFi system, but is not limited thereto.

[0051] In some embodiments, the technical solution of the present disclosure can be applied to the Open RAN architecture. In this case, the interfaces between or within the access network devices involved in the embodiments of the present disclosure can be transformed into internal interfaces of the Open RAN, and the processes and information interactions between these internal interfaces can be implemented through software or programs.

[0052] In some embodiments, the access network device can be composed of a centralized unit (CU) and a distributed unit (DU), where the CU can also be called a control unit. The CU-DU structure can be used to split the protocol layer of the access network device, with the functions of some protocol layers centrally controlled by the CU, and the functions of the remaining part or all of the protocol layers distributed in the DU, which is centrally controlled by the CU, but is not limited to this.

[0053] In some embodiments, a core network device may be a single device comprising one or more network elements, or may be a plurality of devices or device groups, each comprising all or part of one or more network elements. A network element may be virtual or physical. The core network may, for example, comprise at least one of an Evolved Packet Core (EPC), a 5G Core Network (5GCN), or a Next Generation Core (NGC).

[0054] It can be understood that the communication system described in the embodiment of the present disclosure is for the purpose of more clearly illustrating the technical solution of the embodiment of the present disclosure, and does not constitute a limitation on the technical solution proposed in the embodiment of the present disclosure. Ordinary technicians in this field can know that with the evolution of the system architecture and the emergence of new business scenarios, the technical solution proposed in the embodiment of the present disclosure is also applicable to similar technical problems.

[0055] The following embodiments of the present disclosure may be applied to the communication system 100 shown in Figure 1, or a portion thereof, but are not limited thereto. The entities shown in Figure 1 are illustrative only. The communication system may include all or part of the entities shown in Figure 1, or may include other entities outside of Figure 1. The number and form of the entities may be arbitrary. The connection relationship between the entities is illustrative only. The entities may be connected or disconnected, and the connection may be in any manner, including direct or indirect, wired or wireless.

[0056] The embodiments of the present disclosure can be applied to Long Term Evolution (LTE), LTE-Advanced (LTE-A), LTE-Beyond (LTE-B), SUPER 3G, IMT-Advanced, 4th generation mobile communication system (4G), 5th generation mobile communication system (5G), 5G new radio (NR), future radio access (FRA), new radio access technology (RAT), new radio (NR), new radio access (NX), future generation radio access (FX), Global System for Mobile communications (GSM (registered trademark)), CDMA2000, Ultra Mobile Broadband (UMB), IEEE 802.11 (Wi-Fi (registered trademark)), IEEE 802.16 (WiMAX (registered trademark)), IEEE 802.20, Ultra-WideBand (UWB), Bluetooth (registered trademark), Public Land Mobile Network (PLMN) networks, Device-to-Device (D2D) systems, Machine-to-Machine (M2M) systems, Internet of Things (IoT) systems, Vehicle-to-Everything (V2X), systems utilizing other communication methods, and next-generation systems based on and extending these methods. Furthermore, multiple systems may be combined (for example, a combination of LTE or LTE-A with 5G).

[0057] Optionally, the time unit may be, for example, a symbol, a sub-time slot, a time slot, or a frame, without limitation thereto. The following description may take the time unit as a symbol for example, without limitation thereto.

[0058] Optionally, in order to improve uplink (UL) coverage and throughput. In some communication protocols, subband full duplex (SBFD) will be studied. Specifically, a carrier component (CC) is divided into multiple subbands (SBs) in the frequency domain on a downlink (DL) or flexible (F) symbol. The multiple SBs include a UL subband and at least one (1 or 2) DL subband. The base station can send DL signals on the DL subband and receive UL signals on the UL subband at the same time. The DL or F symbol is a TDD-UL-DL-ConfigCommon or TDD-UL-DL-ConfigDedicated configuration or a DCI2-0 indication of DL or F. When a symbol contains both a DL subband and a UL subband in the frequency domain, it can be called an SBFD symbol. Similarly, when a time slot contains multiple symbols including at least one SBFD symbol, the time slot can be called an SBFD time slot. Figure 2 shows a schematic diagram of SBFD time slots, with the horizontal axis representing time and the vertical axis representing frequency. Time slot #0 is a DL time slot, containing 14 DL symbols. Time slots #1-3 are SBFD time slots, each containing 14 SBFD symbols. Time slot #4 is a UL time slot, containing 14 UL symbols.

[0059] Optionally, there may be a guard band (GB) between the DL subband and the UL subband to reduce the interference between the DL signal in the DL subband and the UL signal in the UL subband through frequency domain isolation. In the SBFD symbol, the GB and the DL subband cannot be used for UL transmission, and the UL subband can be used for UL transmission. In the SBFD symbol, the frequency domain range that can be used for UL transmission can be called the UL available frequency domain range, and the frequency domain range that cannot be used for UL transmission can be called the UL unavailable frequency domain range. Therefore, the UL frequency domain range of non-SBFD symbols and SBFD symbols is different. The UL available frequency domain range is the UL frequency domain range on the CC. In the SBFD symbol, the UL available frequency domain range on the UL part bandwidth (Bandwidth Part, BWP) refers to the frequency domain range where the BWP overlaps with the UL available frequency domain range on the CC.

[0060] Optionally, when the UE is in idle state and initially accesses a cell, it measures information such as the received signal strength of the synchronization signal and physical broadcast channel block (SSB) beam, and selects the optimal SSB beam. In the optimal SSB beam direction, 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 UE can also send a PRACH signal at the RO for random access. Random access includes contention-based random access (CBRA) and contention-free random access (CFRA). In CBRA, there are multiple UEs using the same preamble, that is, the PRACH signals of two UEs collide, which will cause random access to fail.

[0061] Optionally, in SBFD symbols, the UE can transmit uplink signals in the UL SB. Therefore, configuring ROs in SBFD symbols increases the number of ROs compared to configuring ROs only in UL or F symbols. UEs that recognize SBFD symbol configurations (SBFD-aware UEs) 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.

[0062] Optionally, the information 3-physical uplink shared channel (Msg3-PUSCH) in the 4-step random access or the information A-physical uplink shared channel (MsgA-PUSCH) in the 2-step random access is sent on the sub-band full-duplex SBFD time unit (SBFD time unit) and the non-sub-band full-duplex non-SBFD time unit (non-SBFD time unit). The performance of the base station receiving Msg3-PUSCH or MsgA-PUSCH varies greatly. Therefore, it is necessary to clarify the time unit category that can be used for Msg3-PUSCH and / or MsgA-PUSCH to ensure the transmission performance of Msg3-PUSCH and / or MsgA-PUSCH.

[0063] The network-side configuration described in this disclosure may include high-level configuration, dynamic indication, or both high-level configuration and dynamic indication, wherein the high-level configuration may include, but is not limited to, configuration via a Radio Resource Control (RRC) message sent by a base station. The dynamic indication may include, but is not limited to, indication via downlink control information (DCI) or a media access control element (MAC CE).

[0064] FIG3A is an interactive diagram illustrating a signal transmission method according to an embodiment of the present disclosure. As shown in FIG3A , the present disclosure embodiment relates to a signal transmission method that can be used in a communication system 100. The method includes:

[0065] Step S3101: Determine the time unit category that can be used to transmit the first signal according to the time unit category of the second signal.

[0066] The execution subject of this embodiment may be a network device or a terminal, which is not limited.

[0067] The determined usable time unit category can be used to transmit the first signal.

[0068] For example, the network device may determine the time unit category that can be used to transmit the first signal based on the time unit category in which the second signal is located; or, the terminal may determine the time unit category that can be used to transmit the first signal based on the time unit category in which the second signal is located; the network device and the terminal determine that the time unit category that can be used to transmit the first signal is the same based on the time unit category in which the second signal is located; and the terminal uses the available time unit category to transmit the first signal.

[0069] In some embodiments, the second signal includes at least one of the following: Message 1-PRACH (Msg1-PRACH) in 4-step random access; Message A-PRACH (MsgA-PRACH) in 2-step random access. Thus, it is possible to effectively determine the time unit type that can be used to transmit the first signal by referring to the time unit type of Msg1-PRACH or MsgA-PRACH.

[0070] In some embodiments, the first signal includes at least one of the following: Message 3-PUSCH (Msg3-PUSCH) in 4-step random access; Message A-PUSCH (MsgA-PUSCH) in 2-step random access. Thus, it is possible to effectively determine the time unit type that can be used to transmit Msg3-PUSCH or MsgA-PUSCH by referring to the time unit type of the second signal.

[0071] In some embodiments, the time unit type includes at least one of the following: a sub-band full-duplex (SBFD) time unit; and a non-sub-band full-duplex (non-SBFD) time unit. This effectively clarifies the time unit type that can be used by Msg3-PUSCH and / or MsgA-PUSCH.

[0072] The SBFD time unit may be, for example, an SBFD symbol, an SBFD sub-time slot, an SBFD time slot, or an SBFD frame, without limitation. The non-SBFD time unit may be, for example, a non-SBFD symbol, a non-SBFD sub-time slot, a non-SBFD time slot, or a non-SBFD frame, without limitation.

[0073] In some embodiments, when the second signal is in the SBFD time unit, it may be determined that the usable time unit category is the SBFD time unit.

[0074] In some embodiments, when the second signal is in an SBFD time unit, it may be determined that the usable time unit category is an SBFD time unit or a non-SBFD time unit.

[0075] In some embodiments, when the second signal is in a non-SBFD time unit, it may be determined that the usable time unit category is a non-SBFD time unit.

[0076] In some embodiments, when the second signal is in a non-SBFD time unit, it may be determined that the available time unit category is a SBFD time unit or a non-SBFD time unit.

[0077] Therefore, the flexibility of determining the time unit category that can be used to transmit the first signal can be effectively improved, and it is effectively applicable to personalized communication scenarios.

[0078] In some embodiments, any of the following can be performed through protocol default and / or high-level configuration and / or dynamic indication: when the second signal is in an SBFD time unit, determining that the time unit category available for transmission of the first signal is an SBFD time unit; and when the second signal is in an SBFD time unit, determining that the time unit category available for transmission is an SBFD time unit or a non-SBFD time unit. This allows for flexible selection of different determination methods to support determining the time unit category available for transmission of the first signal based on the time unit category of the second signal.

[0079] In some embodiments, any of the following can be performed through protocol default and / or high-level configuration and / or dynamic indication: when the second signal is in a non-SBFD time unit, determining that the time unit category available for transmission of the first signal is a non-SBFD time unit; when the second signal is in a non-SBFD time unit, determining that the time unit category available for transmission is an SBFD time unit or a non-SBFD time unit. This allows for flexible selection of different determination methods to support determining the time unit category available for transmission of the first signal based on the time unit category of the second signal.

[0080] In some embodiments, a size comparison between the interference of the SBFD time unit and the interference of the non-SBFD time unit may be determined, and different determination methods may be selected based on the size comparison.

[0081] In some embodiments, if the interference in an SBFD time unit is less than the interference in a non-SBFD time unit, any of the following can be performed through protocol default and / or high-level configuration and / or dynamic indication: when the second signal is in an SBFD time unit, determining that the time unit category available for transmission of the first signal is an SBFD time unit; when the second signal is in a non-SBFD time unit, determining that the time unit category available for transmission is an SBFD time unit or a non-SBFD time unit. This effectively ensures that the interference in the time unit category of the first signal does not exceed the interference in the time unit category of the second signal, thereby ensuring the transmission performance of the first signal.

[0082] For example, if the interference of the SBFD time unit is less than the interference of the non-SBFD time unit, then when it is determined that the second signal is in the SBFD time unit, it is determined that the time unit category available for transmitting the first signal is the SBFD time unit.

[0083] For example, if the interference of the SBFD time unit is less than the interference of the non-SBFD time unit, then when it is determined that the second signal is in the non-SBFD time unit, it is determined that the time unit category that can be used to transmit the first signal is the SBFD time unit or the non-SBFD time unit.

[0084] In some embodiments, if the interference of an SBFD time unit is greater than the interference of a non-SBFD time unit, any of the following can be performed through protocol default and / or high-layer configuration and / or dynamic indication: when the second signal is in an SBFD time unit, determining whether the available time unit category is an SBFD time unit or a non-SBFD time unit; when the second signal is in a non-SBFD time unit, determining whether the available time unit category is a non-SBFD time unit. This effectively ensures that the interference of the time unit category in which the first signal resides does not exceed the interference of the time unit category in which the second signal resides, thereby ensuring the transmission performance of the first signal.

[0085] For example, if the interference of the SBFD time unit is greater than the interference of the non-SBFD time unit, when it is determined that the second signal is in the SBFD time unit, it is determined that the usable time unit category is the SBFD time unit or the non-SBFD time unit.

[0086] For example, if the interference of the SBFD time unit is greater than the interference of the non-SBFD time unit, then when it is determined that the second signal is in the non-SBFD time unit, it is determined that the usable time unit category is the non-SBFD time unit.

[0087] In some embodiments, if the interference of the SBFD time unit is equal to the interference of the non-SBFD time unit, or the comparison result between the interference of the SBFD time unit and the interference of the non-SBFD time unit is not determined, any one of the following can be performed through protocol default and / or high-level configuration and / or dynamic indication: when the second signal is in the SBFD time unit, determine that the usable time unit category is the SBFD time unit; or when the second signal is in the non-SBFD time unit, determine that the usable time unit category is the non-SBFD time unit.

[0088] In some embodiments, if the interference of the SBFD time unit is equal to the interference of the non-SBFD time unit, or the comparison result between the interference of the SBFD time unit and the interference of the non-SBFD time unit is not determined, any one of the following can be performed through protocol default and / or high-level configuration and / or dynamic indication: when the second signal is in the SBFD time unit, determine that the available time unit category is the SBFD time unit or the non-SBFD time unit; or when the second signal is in the non-SBFD time unit, determine that the available time unit category is the SBFD time unit or the non-SBFD time unit.

[0089] Therefore, because the interference in SBFD time units is equal to the interference in non-SBFD time units, or because the strength of the interference in SBFD time units and non-SBFD time units is unknown, the transmission performance of the first signal can be guaranteed by configuring the time units in which the first and second signals are located to be of the same type. Alternatively, no restriction is placed on the time unit type in which the second signal is located, increasing the transmission opportunities for the second signal when the interference situation is unknown.

[0090] Step S3102: Transmit a first signal according to an available time unit type.

[0091] After determining the time unit category that can be used by the first signal, the first signal can be transmitted according to the available time unit category.

[0092] For example, the terminal may transmit the first signal to the first device according to the available time unit category, where the first device is, for example, a network device.

[0093] The signal transmission method involved in the embodiments of the present disclosure may include at least one of steps S3101 and S3102. For example, step S3101 can be implemented as an independent embodiment, step S3102 can be implemented as an independent embodiment, and so on, but the present disclosure is not limited thereto.

[0094] In this embodiment or example, unless there is any contradiction, each step can be independent, arbitrarily combined or exchanged in order, the optional methods or optional examples can be arbitrarily combined, and can be arbitrarily combined with any steps of other embodiments or other examples.

[0095] In this embodiment, by determining the time unit category that can be used to transmit the first signal based on the time unit category in which the second signal is located, and transmitting the first signal based on the available time unit category, it is possible to refer to the time unit category in which the second signal is located to clarify the time unit category that can be used to transmit the first signal, thereby ensuring the transmission performance of the first signal.

[0096] It should be noted that, for the description of the terms and method steps in the following embodiments that are the same as or corresponding to those in the above embodiments, please refer to the above embodiments for details and will not be repeated below.

[0097] FIG3B is an interactive diagram illustrating a signal transmission method according to another embodiment of the present disclosure. As shown in FIG3B , the present disclosure embodiment relates to a signal transmission method that can be used in a communication system 100. The method includes:

[0098] Step S3201: Determine a time unit type that can be used to transmit a first signal according to a reference signal received power RSRP of a reference signal.

[0099] The execution subject of this embodiment may be a network device or a terminal, which is not limited.

[0100] The determined usable time unit category can be used to transmit the first signal.

[0101] For example, the network device may determine the time unit category that can be used to transmit the first signal based on the RSRP of the reference signal; or, the terminal may determine the time unit category that can be used to transmit the first signal based on the RSRP of the reference signal; the network device and the terminal determine that the time unit category that can be used to transmit the first signal is the same based on the RSRP of the reference signal; and the terminal uses the usable time unit category to transmit the first signal.

[0102] In some embodiments, the reference signal may be, for example, an SSB and / or a channel state information reference signal (CSI-RS).

[0103] In some embodiments, the beam of the reference signal may be the beam used by the second signal.

[0104] In some embodiments, the first signal includes at least one of the following: Message 3-PUSCH (Msg3-PUSCH) in 4-step random access; Message A-PUSCH (MsgA-PUSCH) in 2-step random access. This effectively enables determining the type of time unit available for transmitting Msg3-PUSCH or MsgA-PUSCH based on the RSRP of the reference signal.

[0105] In some embodiments, a size comparison between the RSRP of the reference signal and the threshold of the reference signal received power RSRP of the reference signal can be determined, and an appropriate determination method can be selected based on the size comparison to determine the time unit category that can be used to transmit the first signal.

[0106] In some embodiments, the RSRP threshold of the reference signal may include a first threshold and / or a second threshold, where the first threshold is greater than the second threshold. The first threshold and / or the second threshold may be set by protocol default, configured by a higher layer, and / or dynamically indicated. This allows timely and accurate knowledge of the threshold configured for the RSRP of the reference signal.

[0107] In some embodiments, the RSRP threshold of the reference signal may also be included in the configuration information of the first signal and / or the second signal of the terminal, and there is no limitation to this.

[0108] In some embodiments, when the RSRP of the reference signal is greater than or equal to a first threshold, it may be determined that the usable time unit category is a non-SBFD time unit.

[0109] In some embodiments, when the RSRP of the reference signal is greater than or equal to a first threshold, it may be determined that the usable time unit category is the SBFD time unit.

[0110] In some embodiments, when the RSRP of the reference signal is greater than or equal to a first threshold, it may be determined that the usable time unit category is an SBFD time unit or a non-SBFD time unit.

[0111] In some embodiments, when the RSRP of the reference signal is less than a first threshold, or the RSRP is less than the first threshold and greater than or equal to a second threshold, it may be determined that the usable time unit category is a non-SBFD time unit.

[0112] In some embodiments, when the RSRP of the reference signal is less than a first threshold, or the RSRP is less than the first threshold and greater than or equal to a second threshold, it may be determined that the usable time unit category is the SBFD time unit.

[0113] In some embodiments, when the RSRP of the reference signal is less than a first threshold, or the RSRP is less than the first threshold and greater than or equal to a second threshold, it can be determined that the usable time unit category is an SBFD time unit or a non-SBFD time unit.

[0114] In some embodiments, when the RSRP of the reference signal is less than a second threshold, it may be determined that the usable time unit category is a non-SBFD time unit.

[0115] In some embodiments, when the RSRP of the reference signal is less than a second threshold, it may be determined that the usable time unit category is the SBFD time unit.

[0116] In some embodiments, when the RSRP of the reference signal is less than a second threshold, it may be determined that the usable time unit category is an SBFD time unit or a non-SBFD time unit.

[0117] Therefore, the flexibility of determining the time unit category that can be used to transmit the first signal can be effectively improved, and it is effectively applicable to personalized communication scenarios.

[0118] In some embodiments, a size comparison between the interference of the SBFD time unit and the interference of the non-SBFD time unit can be determined, and an appropriate determination method can be selected based on the size comparison to determine the time unit category that can be used to transmit the first signal based on the RSRP of the reference signal.

[0119] In some embodiments, when the interference of SBFD time units is less than the interference of non-SBFD time units, the usable time unit category can be determined to be SBFD time units or non-SBFD time units when it is determined that the RSRP is greater than or equal to a first threshold, through protocol default and / or higher-layer configuration and / or dynamic indication. Thus, since the RSRP is greater than or equal to the first threshold, indicating that the UE has good coverage, the first signal can achieve good performance when using both time unit categories, thereby effectively ensuring the transmission performance of the first signal.

[0120] In some embodiments, when the interference of SBFD time units is less than that of non-SBFD time units, it can be determined, through protocol default and / or higher-layer configuration and / or dynamic indication, that the usable time unit category is an SBFD time unit when it is determined that the RSRP is less than a first threshold, or the RSRP is less than the first threshold and greater than or equal to a second threshold. Thus, when the UE has general coverage, the first signal uses the SBFD time unit, ensuring that the first signal is transmitted in the time unit category with less interference, thereby ensuring the transmission performance of the first signal.

[0121] In some embodiments, if the interference of SBFD time units is greater than the interference of non-SBFD time units, the usable time unit type may be determined to be either SBFD time units or non-SBFD time units when the RSRP is greater than or equal to a first threshold, through protocol default and / or higher-layer configuration and / or dynamic indication. Thus, since the RSRP is greater than or equal to the first threshold, indicating that the UE has good coverage, the first signal can achieve good performance when using both time unit types, thereby ensuring the transmission performance of the first signal.

[0122] In some embodiments, if the interference of SBFD time units is greater than the interference of non-SBFD time units, the usable time unit category can be determined to be non-SBFD time units when the RSRP is less than a first threshold, or when the RSRP is less than the first threshold and greater than or equal to a second threshold, through protocol default and / or higher-layer configuration and / or dynamic indication. Thus, when UE coverage is average, the first signal uses non-SBFD time units, ensuring that the first signal is transmitted in a time unit category with less interference, thereby guaranteeing the transmission performance of the first signal.

[0123] In some embodiments, if the interference of SBFD time units is equal to the interference of non-SBFD time units, or the comparison result between the interference of SBFD time units and the interference of non-SBFD time units is not determined, any of the following is performed through protocol default and / or higher-layer configuration and / or dynamic indication: when RSRP is greater than or equal to a first threshold, determining that the usable time unit category is SBFD time units or non-SBFD time units; or when RSRP is less than the first threshold, or when RSRP is less than the first threshold and greater than or equal to a second threshold, determining that the usable time unit category is SBFD time units or non-SBFD time units; or when RSRP is less than the second threshold, determining that the usable time unit category is SBFD time units or non-SBFD time units. Because the interference of SBFD time units is equal to the interference of non-SBFD time units, or the interference strength between SBFD time units and non-SBFD time units is unknown, a certain threshold can be set to ensure that the transmission performance of the first signal on both time unit categories is better.

[0124] Step S3202: Transmit a first signal according to an available time unit type.

[0125] After determining the time unit category that can be used by the first signal, the first signal can be transmitted according to the available time unit category.

[0126] For example, the terminal may transmit the first signal to the first device according to the available time unit category, where the first device is, for example, a network device.

[0127] The signal transmission method involved in the embodiments of the present disclosure may include at least one of steps S3201 and S3202. For example, step S3201 can be implemented as an independent embodiment, step S3202 can be implemented as an independent embodiment, and so on, but the present disclosure is not limited thereto. Steps S3201+S3202 can be implemented as independent embodiments, but the present disclosure is not limited thereto.

[0128] In this embodiment or example, unless there is any contradiction, each step can be independent, arbitrarily combined or exchanged in order, the optional methods or optional examples can be arbitrarily combined, and can be arbitrarily combined with any steps of other embodiments or other examples.

[0129] In this embodiment, by determining the time unit category that can be used to transmit the first signal based on the RSRP of the reference signal, and transmitting the first signal based on the available time unit category, it is possible to clarify the time unit category that can be used to transmit the first signal based on the RSRP of the reference signal to ensure the transmission performance of the first signal.

[0130] FIG3C is an interactive diagram of a signal transmission method according to another embodiment of the present disclosure. As shown in FIG3C , the present disclosure embodiment relates to a signal transmission method that can be used in a communication system 100. The method includes:

[0131] Step S3301: Determine a time unit type that can be used to transmit the first signal according to the preamble group where the second signal is located.

[0132] The execution subject of this embodiment may be a network device or a terminal, which is not limited.

[0133] The determined usable time unit category can be used to transmit the first signal.

[0134] The preamble group can be expressed as preamble Group.

[0135] In some embodiments, the type of time unit that can be used to transmit the first signal may be determined based on the preamble Group to which the second signal belongs.

[0136] For example, the network device may determine the time unit category that can be used to transmit the first signal based on the preamble group where the second signal is located; or, the terminal may determine the time unit category that can be used to transmit the first signal based on the preamble group where the second signal is located; the network device and the terminal determine that the time unit category that can be used to transmit the first signal is the same based on the preamble group where the second signal is located; and the terminal uses the available time unit category to transmit the first signal.

[0137] In some embodiments, the second signal includes at least one of the following: Message 1-PRACH (Msg1-PRACH) in 4-step random access; Message A-PRACH (MsgA-PRACH) in 2-step random access. This effectively enables reference to the preamble group in which Msg1-PRACH or MsgA-PRACH resides to determine the type of time unit available for transmitting the first signal.

[0138] In some embodiments, the first signal includes at least one of the following: Message 3-PUSCH (Msg3-PUSCH) in 4-step random access; Message A-PUSCH (MsgA-PUSCH) in 2-step random access. This effectively determines the type of time unit available for transmitting Msg3-PUSCH or MsgA-PUSCH based on the preamble group to which the second signal belongs.

[0139] In some embodiments, when the second signal is in preamble group B, it is determined that the usable time unit category is a non-SBFD time unit.

[0140] In some embodiments, when the second signal is in preamble group B, it is determined that the usable time unit category is the SBFD time unit.

[0141] In some embodiments, when the second signal is in preamble group B, it is determined that the usable time unit category is a SBFD time unit or a non-SBFD time unit.

[0142] In some embodiments, when the second signal is in preamble group A, it is determined that the usable time unit category is a non-SBFD time unit.

[0143] In some embodiments, when the second signal is in preamble group A, it is determined that the usable time unit category is the SBFD time unit.

[0144] In some embodiments, when the second signal is in preamble group A, it is determined that the usable time unit category is a SBFD time unit or a non-SBFD time unit.

[0145] Therefore, the flexibility of determining the time unit category that can be used to transmit the first signal can be effectively improved, and it is effectively applicable to personalized communication scenarios.

[0146] In some embodiments, the size comparison between the interference of the SBFD time unit and the interference of the non-SBFD time unit can be performed, and an appropriate determination method can be selected based on the size comparison to determine the time unit category that can be used to transmit the first signal based on the preamble code group where the second signal is located.

[0147] In some embodiments, if the interference of SBFD time units is less than that of non-SBFD time units, the usable time unit type can be determined to be either SBFD time units or non-SBFD time units when the second signal is in preamble group B, by protocol default and / or higher-layer configuration and / or dynamic indication. Thus, due to good coverage of the UE, the first signal can achieve good performance when using both time unit types, thereby effectively ensuring the transmission performance of the first signal.

[0148] In some embodiments, if the interference in SBFD time units is less than that in non-SBFD time units, the usable time unit category can be determined to be SBFD time units when the second signal is in preamble group A, by protocol default, / or higher-layer configuration, and / or dynamic indication. Thus, the first signal uses SBFD time units, ensuring that the first signal is transmitted in a time unit category with less interference, thereby ensuring the transmission performance of the second signal.

[0149] In some embodiments, if the interference of SBFD time units is greater than the interference of non-SBFD time units, the usable time unit type can be determined to be SBFD time units or non-SBFD time units when the second signal is in preamble group B, through protocol default and / or higher-layer configuration and / or dynamic indication. Therefore, due to good coverage of the UE, the first signal can achieve good performance when using both time unit types, thereby effectively ensuring the transmission performance of the first signal.

[0150] In some embodiments, if the interference of SBFD time units is greater than the interference of non-SBFD time units, the usable time unit category can be determined to be non-SBFD time units when the second signal is in preamble group A, through protocol default and / or high-layer configuration and / or dynamic indication. Thus, the first signal uses non-SBFD time units, ensuring that the first signal is transmitted in a time unit category with less interference, thereby ensuring the transmission performance of the first signal.

[0151] In some embodiments, if the interference of an SBFD time unit is equal to the interference of a non-SBFD time unit, or the comparison result between the interference of an SBFD time unit and the interference of a non-SBFD time unit is not determined, any of the following may be performed through protocol default and / or high-level configuration and / or dynamic indication: when the second signal is in preamble group B, determining whether the available time unit category is an SBFD time unit or a non-SBFD time unit; or when the second signal is in preamble group A, determining whether the available time unit category is an SBFD time unit or a non-SBFD time unit. This can effectively enhance the flexibility of determining the available time unit category for transmitting the first signal and effectively apply to personalized communication scenarios.

[0152] In some embodiments, the preamble group A may be expressed as preamble Group A. The preamble group B may be expressed as preamble Group B.

[0153] Step S3302: Transmit a first signal according to an available time unit type.

[0154] After determining the time unit category that can be used by the first signal, the first signal can be transmitted according to the available time unit category.

[0155] For example, the terminal may transmit the first signal to the first device according to the available time unit category, where the first device is, for example, a network device.

[0156] The signal transmission method involved in the embodiments of the present disclosure may include at least one of steps S3301 and S3302. For example, step S3301 can be implemented as an independent embodiment, step S3302 can be implemented as an independent embodiment, and so on, but the present disclosure is not limited thereto. Steps S3301 and S3302 can be implemented as independent embodiments, but the present disclosure is not limited thereto.

[0157] In this embodiment or example, unless there is any contradiction, each step can be independent, arbitrarily combined or exchanged in order, the optional methods or optional examples can be arbitrarily combined, and can be arbitrarily combined with any steps of other embodiments or other examples.

[0158] In this embodiment, by determining the time unit category that can be used to transmit the first signal based on the preamble code group where the second signal is located, and transmitting the first signal based on the available time unit category, it is possible to clarify the time unit category that can be used to transmit the first signal based on the preamble code group where the second signal is located, thereby ensuring the transmission performance of the first signal.

[0159] FIG3D is an interactive schematic diagram of a signal transmission method according to another embodiment of the present disclosure. As shown in FIG3D , the present disclosure embodiment relates to a signal transmission method that can be used in a communication system 100. The method includes:

[0160] Step S3401: Determine a time unit type that can be used to transmit the first signal according to the power configuration of the first signal and / or the second signal in the configuration information of the first signal and / or the second signal.

[0161] The execution subject of this embodiment can be a network device or a terminal, and there is no limitation on this.

[0162] The determined usable time unit category can be used to transmit the first signal.

[0163] For example, the network device may determine the category of time units that can be used to transmit the first signal based on the power configuration of the first signal and / or the second signal in the configuration information of the first signal and / or the second signal; or, the terminal may determine the category of time units that can be used to transmit the first signal based on the power configuration of the first signal and / or the second signal in the configuration information of the first signal and / or the second signal; the network device and the terminal determine that the category of time units that can be used to transmit the first signal is the same based on the power configuration of the first signal and / or the second signal in the configuration information of the first signal and / or the second signal; and the terminal uses the available time unit category to transmit the first signal.

[0164] In some embodiments, the second signal includes at least one of the following: Message 1-PRACH (Msg1-PRACH) in 4-step random access; Message A-PRACH (MsgA-PRACH) in 2-step random access. This effectively enables determining the type of time unit that can be used to transmit the first signal by referring to the power configuration of Msg1-PRACH or MsgA-PRACH.

[0165] In some embodiments, the first signal includes at least one of the following: Message 3-PUSCH (Msg3-PUSCH) in 4-step random access; Message A-PUSCH (MsgA-PUSCH) in 2-step random access. This effectively enables reference to the power configuration of the first signal and / or the second signal in the configuration information of the first signal and / or the second signal to determine the type of time unit available for transmitting the Msg3-PUSCH or MsgA-PUSCH.

[0166] In some embodiments, the power configuration of the first signal and / or the second signal may be included in the configuration information of the first signal and / or the second signal, thereby, the power configuration of the first signal and / or the second signal may be obtained from the configuration information of the first signal and / or the second signal.

[0167] In some embodiments, the configuration information of the first signal and / or the second signal may include PRACH resource configuration information and / or other resource configuration information, which is not limited.

[0168] In some embodiments, the power configuration of the first signal and / or the second signal may be included in the PRACH resource configuration information and / or other resource configuration information.

[0169] In some embodiments, if the power configuration of the first signal and / or the second signal in the configuration information of the first signal and / or the second signal is a differentiated configuration in SBFD time units and non-SBFD time units, the available time unit category is determined to be SBFD time units or non-SBFD time units. Since the first signal and / or the second signal are configured with differentiated power in SBFD and non-SBFD time units, it means that the network has guaranteed the transmission performance of the first signal in SBFD and non-SBFD time units through power differentiation configuration. In this case, the first signal can use both SBFD and non-SBFD time units.

[0170] In some embodiments, if the power configurations of the first signal and the second signal in the configuration information of the first signal and / or the second signal are not differentially configured in SBFD time units and non-SBFD time units, any one of the following may be performed through protocol default and / or high-level configuration and / or dynamic indication: determining the time unit category that can be used to transmit the first signal based on the time unit category in which the second signal is located; or determining the time unit category that can be used to transmit the first signal based on the RSRP of the reference signal; or determining the time unit category that can be used to transmit the first signal based on the preamble code group in which the second signal is located. Since the power of the first signal and the second signal in SBFD time units and non-SBFD time units are not differentially configured, at this time, the scheme in the above embodiment may be used to determine the time unit category that can be used to transmit the first signal, thereby ensuring the transmission performance of the first signal.

[0171] Step S3402: Transmit a first signal according to an available time unit type.

[0172] After determining the time unit category that can be used by the first signal, the first signal can be transmitted according to the available time unit category.

[0173] For example, the terminal may transmit the first signal to the first device according to the available time unit category, where the first device is, for example, a network device.

[0174] The signal transmission method involved in the embodiments of the present disclosure may include at least one of steps S3401 and S3402. For example, step S3401 can be implemented as an independent embodiment, step S3402 can be implemented as an independent embodiment, and so on, but the present disclosure is not limited thereto. Steps S3401+S3402 can be implemented as independent embodiments, but the present disclosure is not limited thereto.

[0175] In this embodiment or example, unless there is any contradiction, each step can be independent, arbitrarily combined or exchanged in order, the optional methods or optional examples can be arbitrarily combined, and can be arbitrarily combined with any steps of other embodiments or other examples.

[0176] In this embodiment, the time unit category that can be used for transmitting the first signal is determined based on the power configuration of the first signal and / or the second signal in the configuration information of the first signal and / or the second signal, and the first signal is transmitted based on the usable time unit category, thereby making it possible to clarify the time unit category that can be used for transmitting the first signal based on the power configuration of the first signal and / or the second signal in the configuration information of the first signal and / or the second signal, so as to ensure the transmission performance of the first signal.

[0342] The specific method is as in terminal side solution 4, which will not be repeated here.

[0343] Further examples of the above description are as follows:

[0344] Example 1:

[0345] Terminal side: The SBFD aware UE determines the symbol type that can be used for Msg3-PUSCH and / or MsgA-PUSCH through the following method.

[0346] The second signal is Msg1-PRACH and the first signal is Msg3-PUSCH. Or the second signal is MsgA-PRACH and the first signal is MsgA-PUSCH.

[0347] Solution 1: Determine the symbol category that can be used by the first signal based on the symbol category of the second signal.

[0348] Option 1-1: The second signal is in the SBFD symbol, and the first signal can be in the SBFD symbol.

[0349] Option 1-2: The second signal is in SBFD symbols, and the first signal can be in SBFD symbols or non-SBFD symbols.

[0354] Optionally, when the interference of SBFD symbols is less than the interference of non-SBFD symbols, Option 1-1 and Option 1-4 are used by protocol default and / or high-layer configuration and / or dynamic indication.

[0356] Optionally, when the interference of SBFD symbols is greater than the interference of non-SBFD symbols, Option 1-2 and Option 1-3 are used by protocol default and / or high-layer configuration and / or dynamic indication.

[0357] Solution 1-3: Use Option 1-1 and Option 1-3 or use Option 1-2 and Option 1-4.

[0358] Optionally, when the interference strengths of SBFD symbols and non-SBFD symbols are unknown, Option 1-1 and Option 1-3 or Option 1-2 and Option 1-4 are used by protocol default and / or high-layer configuration and / or dynamic indication.

[0359] In solutions 1-1 and 1-2, it can be ensured that the interference of the symbol category where the first signal is located does not exceed the symbol category where the second signal is located, so that the transmission performance of the first signal is guaranteed.

[0360] In solutions 1-3, since the interference strength between SBFD and non-SBFD symbols is unknown, the transmission performance of the first signal can be guaranteed by using the same symbol category as the second signal, i.e., using Options 1-1 and 1-3. Alternatively, the second symbol category can be used without restrictions, i.e., using Options 1-2 and 1-4.

[0363] The second signal is Msg1-PRACH and the first signal is Msg3-PUSCH. Or the second signal is MsgA-PRACH and the first signal is MsgA-PUSCH.

[0364] Solution 2: Determine the symbol type that can be used for the first signal according to the RSRP of the reference signal.

[0365] Option 2-1: When the RSRP of the reference signal is greater than or equal to the first threshold, the first signal may be in a non-SBFD symbol.

[0366] Option 2-2: When the RSRP of the reference signal is greater than or equal to the first threshold, the first signal may be in an SBFD symbol.

[0367] Option 2-3: When the RSRP of the reference signal is greater than or equal to the first threshold, the first signal may be in an SBFD symbol or a non-SBFD symbol.

[0368] Option 2-4: When the RSRP of the reference signal is less than the first threshold or less than the first threshold and greater than or equal to the second threshold, the first signal may be in a non-SBFD symbol.

[0369] Option 2-5: When the RSRP of the reference signal is less than the first threshold or less than the first threshold and greater than or equal to the second threshold, the first signal may be in the SBFD symbol.

[0370] Option 2-6: When the RSRP of the reference signal is less than the first threshold or less than the first threshold and greater than or equal to the second threshold, the first signal may be in an SBFD or non-SBFD symbol.

[0371] Option 2-7: When the RSRP of the reference signal is less than the second threshold, the first signal may be in a non-SBFD symbol.

[0372] Option 2-8: When the RSRP of the reference signal is less than the second threshold, the first signal may be in the SBFD symbol.

[0373] Option 2-9: When the RSRP of the reference signal is less than the second threshold, the first signal may be in an SBFD or non-SBFD symbol.

[0374] Optional: Use one or more of Option 1 to Option 9 through protocol default and / or high-level configuration and / or dynamic indication to determine the symbol category that can be used for the first signal.

[0375] Optional: The first threshold and / or the second threshold are set by protocol default and / or configured at a higher level and / or are dynamically indicated.

[0376] Optional: The reference signal is SSB or CSI-RS.

[0377] Solution 2-1: Use Option 2-3 and Option 2-5.

[0378] Optionally, when the interference of SBFD symbols is less than the interference of non-SBFD symbols, Option 2-3 and Option 2-5 are used by protocol default and / or high-layer configuration and / or dynamic indication.

[0379] Solution 2-2: Use Option 2-3 and Option 2-4.

[0380] Optionally, when the interference of SBFD symbols is greater than the interference of non-SBFD symbols, Option 2-3 and Option 2-4 are used by protocol default and / or high-layer configuration and / or dynamic indication.

[0381] Solution 2-3: Use Option 2-3, Option 2-6, or Option 2-9.

[0382] Optionally, when the interference strengths of SBFD symbols and non-SBFD symbols are unknown, Option 2-3, Option 2-6, or Option 2-9 is used by protocol default and / or high-layer configuration and / or dynamic indication.

[0383] The RSRP of the reference signal reflects to a certain extent whether the UE is in good coverage: a larger RSRP of the reference signal indicates that the UE has good coverage; otherwise, the UE has poor coverage.

[0384] In solution 2-1, using Option 2-3 indicates good UE coverage. In this case, the performance of the first signal using both symbol classes is not significantly reduced, ensuring the transmission performance of the first signal. Using Option 2-5 indicates fair UE coverage. Using SBFD symbols for the first signal ensures that the first signal is transmitted on a symbol class with less interference, ensuring the transmission performance of the first signal.

[0385] In solution 2-2, using Option 2-3 indicates good UE coverage. In this case, the performance of the first signal using both symbol classes is not too poor, ensuring the transmission performance of the first signal. Using Option 2-4 indicates fair UE coverage. In this case, the first signal uses non-SBFD symbols, ensuring that the first signal is transmitted on a symbol class with less interference, thus ensuring the transmission performance of the first signal.

[0386] In solution 2-3, since the interference strength of SBFD and non-SBFD symbols is unknown, a certain threshold can be set to ensure that the UE's transmission performance of the first signal in both symbol categories is not too bad.

[0387] Example 3:

[0388] Terminal side: The SBFD aware UE determines the symbol type that can be used for Msg3-PUSCH and / or MsgA-PUSCH through the following method.

[0389] The second signal is Msg1-PRACH and the first signal is Msg3-PUSCH or the second signal is MsgA-PRACH and the first signal is MsgA-PUSCH.

[0390] Solution 3: Determine the symbol type that can be used by the first signal according to the preamble group to which the second signal belongs.

[0391] Option 3-1: The second signal is in preamble Group B, and the first signal can be in non-SBFD symbols.

[0392] Option 3-2: The second signal is in preamble Group B, and the first signal can be in the SBFD symbol.

[0393] Option 3-3: The second signal is in preamble Group B, and the first signal can be in SBFD symbols or non-SBFD symbols.

[0394] Option 3-4: The second signal is in preamble Group A, and the first signal can be in non-SBFD symbols.

[0395] Option 3-5: The second signal is in preamble Group A, and the first signal can be in the SBFD symbol.

[0396] Option 3-6: The second signal is in preamble Group A, and the first signal can be in SBFD symbols or non-SBFD symbols.

[0397] Optional: Use one or more of Option 1 to Option 6 through protocol default and / or high-level configuration and / or dynamic indication to determine the symbol category that can be used for the first signal.

[0398] Solution 3-1: Use Option 3-3 and Option 3-5.

[0399] Optionally, when the interference of SBFD symbols is less than the interference of non-SBFD symbols, Option 3-3 and Option 3-5 are used by protocol default and / or high-layer configuration and / or dynamic indication.

[0400] Solution 3-2: Use Option 3-3 and Option 3-4.

[0401] Optionally, when the interference of SBFD symbols is less than the interference of non-SBFD symbols, Option 3-3 and Option 3-4 are used by protocol default and / or high-layer configuration and / or dynamic indication.

[0402] The second signal uses Preamble Group B, indicating that the UE has good coverage and the first signal needs to carry a larger number of bits; the second signal uses Preamble Group A, indicating that the UE has poor coverage or the first signal needs to carry a smaller number of bits.

[0403] In Solution 3-1, using Option 3-3 indicates good UE coverage. In this case, the performance of the first signal using both symbol classes is not too poor, ensuring the transmission performance of the first signal. Using Option 3-5 may indicate poor UE coverage. In this case, using SBFD symbols for the first signal ensures that the first signal is transmitted on a symbol class with less interference, thus ensuring the transmission performance of the first signal.

[0404] In Solution 3-2, using Option 3-3 indicates good UE coverage. In this case, the performance of the first signal using both symbol classes is not too poor, ensuring the transmission performance of the first signal. Using Option 3-4 may indicate poor UE coverage. In this case, the first signal uses non-SBFD symbols, ensuring that the first signal is transmitted on a symbol class with less interference, thus ensuring the transmission performance of the first signal.

[0405] Example 4:

[0406] Terminal side: The SBFD aware UE determines the symbol type that can be used for Msg3-PUSCH and / or MsgA-PUSCH through the following method.

[0407] The second signal is Msg1-PRACH and the first signal is Msg3-PUSCH or the second signal is MsgA-PRACH and the first signal is MsgA-PUSCH.

[0408] Solution 4: Determine the symbol category that can be used for the first signal according to the power configuration of the second signal and / or the first signal in the configuration information of the first signal and / or the second signal.

[0409] Solution 4-1: The second signal and / or the first signal are configured with differential power in SBFD and non-SBFD symbols, and the first signal can be in SBFD or non-SBFD symbols.

[0410] Solution 4-2: The symbol powers of the second signal and the first signal are not configured differently in SBFD and non-SBFD, and the symbol category that can be used by the first signal is determined using the methods in Solution 1 to Solution 3.

[0411] In solution 4-1, the power differential configuration of the second signal and / or the first signal in SBFD and non-SBFD symbols indicates that the network has implemented power differential configuration to ensure the transmission performance of the first signal in both SBFD and non-SBFD symbols. In this case, the first signal can use both SBFD and non-SBFD symbols.

[0412] In Solution 4-2, since the second signal and the first signal are not configured with different symbol powers in SBFD and non-SBFD, solutions 1 to 3 can be used to ensure the transmission performance of the first signal.

[0413] Optionally, there is no restriction on the symbol categories that can be used by the first signal, that is, the first signal can use SBFD and non-SBFD symbol categories, and there is no need to consider the symbol category of the second signal and / or the RSRP of the reference signal and / or the preamble Group in which the second signal is located and / or the power configuration of the second signal and / or the first signal in the configuration information of the first signal and / or the second signal.

[0414] Optionally, the first signal is restricted to use one of SBFD and non-SBFD symbols, and there is no need to consider the symbol category of the second signal and / or the RSRP of the reference signal and / or the preamble Group to which the second signal is located and / or the power configuration of the second signal and / or the first signal in the configuration information of the first signal and / or the second signal.

[0415] The second signal is MsgA-PRACH, and the first signal is MsgA-PUSCH. Parameter configuration can be used to enable the symbol category used by the first signal to meet the constraints in Schemes 1 to 4.

[0425] Step 2: The terminal determines a symbol category that can be used for the first signal based on the first information.
