Detailed Implementation

[0039] The embodiments of this application are described in detail below. Examples of the embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain this application, and should not be construed as limiting this application. It should be noted that, unless otherwise specified, the embodiments of this application and the features in the embodiments can be combined with each other.

[0040] To facilitate understanding, the terminology used in this embodiment will be introduced first.

[0041] 1. Sidelink (SL) The communication interface between terminal devices is called the PC-5 interface. On the PC-5 interface, the link for data transmission between terminal devices is called a sidelink. For example... Figure 1As shown, based on the correspondence between the transmitting terminal device 11 and the receiving terminal device 12, three transmission modes can be supported on the side link, including unicast, multicast, and broadcast. The transmitting terminal device 11 and the receiving terminal device 12 can be referred to as a terminal, user equipment (UE), mobile station (MS), mobile terminal device (MT), etc. The transmitting terminal device 11 and the receiving terminal device 12 can also be vehicles with communication capabilities, smart cars, mobile phones, wearable devices, tablets, computers with wireless transceiver capabilities, virtual reality (VR) terminal devices, augmented reality (AR) terminal devices, wireless terminal devices in industrial control, wireless terminal devices in self-driving, wireless terminal devices in remote medical surgery, wireless terminal devices in smart grids, wireless terminal devices in transportation safety, wireless terminal devices in smart cities, wireless terminal devices in smart homes, etc. This embodiment does not limit the specific technology or device form used by the transmitting terminal device 11 and the receiving terminal device 12.

[0042] 2. Listen Before Talk (LBT) LBT is a technology to avoid channel access conflicts. Different terminal devices compete for shared unlicensed spectrum resources through LBT operation.

[0043] 3. ON / OFF time mask The allowed power transient period is determined by the ON / OFF time mask, such as the time when the terminal device switches power from SL RX to SL TX (corresponding to the ON time mask), and the time when the terminal device switches power from SL TX to SL RX (corresponding to the OFF time mask).

[0044] With the Rel-16 standard, 3GPP completed the evolution of NR-U. With the Rel-18 (release 18) standard, SL-U is a research topic, extending sidelink transmission to unlicensed spectrum. However, there is currently a lack of configuration schemes for the ON / OFF time mask of SL-U.

[0045] Therefore, this embodiment proposes a communication configuration method and apparatus, providing a configuration scheme for the ON / OFF timemask of SL-U. In some embodiments, the terms "communication configuration method" and "information processing method" and "communication method" can be used interchangeably, as can the terms "communication configuration apparatus" and "information processing apparatus" and "communication apparatus," and the terms "information processing system" and "communication system."

[0063] The communication configuration method and apparatus provided in this application will be described in detail below with reference to the accompanying drawings.

[0064] Figure 2 A flowchart illustrating a communication configuration method according to an embodiment of this application is shown. Figure 2 As shown, this method is applied to the sending terminal device side (e.g., Figure 1 The sending terminal device 11) in the process may perform the following steps.

[0065] Step 201: Determine the first configuration information based on the CP-E configuration time.

[0066] The first configuration information is used to configure the first power transient period of the transmitting terminal device during the SL TX start phase. For ease of description, the power transient period during the SL TX start phase can be referred to as the first power transient period. The SL TX start phase is the time period corresponding to the transmitting terminal device switching from SL RX to SL TX. This first power transient period is used to determine the time corresponding to the power switch from SL RX to SL TX, and the transmitting terminal device will perform the power switch from SL RX to SL TX according to this time.

[0067] The frame structure of the transmission frame of the side link can adopt the following time slot structure of Orthogonal Frequency Division Multiplexing (OFDM) symbols.

[0068]

[0069] In the frame structure of a sidelink transmission frame, the first symbol is Automatic Gain Control (AGC), and the last symbol is the Guard Period (GP). The symbols in between can correspond to signals such as the Physical Sidelink Control Channel (PSCCH), Physical Sidelink Control Channel (PSSCH), and Physical Sidelink Feedback Channel (PSFCH).

[0070] Based on the frame structure of the transmission frame of the sidelink described above, the start time point of CP-E transmission can be determined as the first L symbols of the AGC symbol, according to the configuration of CP-E of SL-U. L can be a positive integer such as 1 or 2. In this embodiment, the on / off time mask of SL-U can be reconfigured according to the configuration of CP-E of SL-U and / or the frame structure above, to ensure that the terminal device retains sufficient LBT time while having sufficient switching time, and without affecting the data transmission of the sidelink. Specifically, the configuration information of the first power transient cycle of the transmitting terminal device at the beginning of SL TX can be determined according to the configuration time of CP-E, i.e., the first configuration information.

[0071] The communication configuration method provided in this embodiment offers a configuration scheme for the ON / OFF time mask of SL-U. This ensures that the terminal device retains sufficient LBT time while having enough handover time, without affecting data transmission on the side link.

[0072] Figure 3 A flowchart illustrating a communication configuration method according to an embodiment of this application is shown. Based on Figure 2 The illustrated embodiment, as Figure 3 As shown, this method is applied to the sending terminal device side and may include the following steps.

[0073] Step 301: Determine the CP-E configuration time.

[0074] This embodiment can calculate the CP-E configuration time according to the actual situation in order to determine how to place the first power transient cycle of the SL TX start phase within the CP-E configuration time.

[0075] In some examples, step 301 may specifically include: first determining the switching time from SL RX to SL TX; and determining the LBT time and TA; and then determining the CP-E configuration time based on the switching time from SL RX to SL TX, the LBT time, and the TA.

[0076] For example, the switching time between SL RX and SL TX of the terminal device can be determined; and based on the actual situation of network configuration or pre-configuration of the terminal device, the LBT form used by the terminal device can be clearly defined, and the corresponding LBT time can be determined. For side link transmission, the TA of its transmission can be clearly defined accordingly. Based on these time parameters, the configuration time of CP-E can be accurately determined.

[0077] In some examples, the process of determining the handover time from SL RX to SL TX may specifically include: determining a first number of symbols required for the handover from SL RX to SL TX; and determining the symbol length of the SCS; multiplying the first number of symbols by the symbol length of the SCS to obtain the handover time of the terminal device from SL RX to SL TX.

[0078] In some examples, when the first symbol of the AGC symbol is the start time point of CP-E transmission, the first quantity can be 1; while when the first two symbols of the AGC symbol are the start time points of CP-E transmission, the first quantity can be 2.

[0079] For example, the CP-E configuration of SL-U can be divided into the following two cases: Case 1: The symbol preceding the AGC symbol is used as the start time point for CP-E transmission.

[0080] Case 2: When SCS=15kHz, the first symbol configured as an AGC symbol is used as the start time point for CP-E transmission; when SCS=30kHz and 60kHz, the first two symbols configured as AGC symbols are used as the start time points for CP-E transmission.

[0081] This embodiment, based on the actual CP-E configuration of SL-U, determines the T symbols required for switching from SL RX to SL TX. When the first symbol preceding the AGC symbol is the start time of CP-E transmission, T=1; when the first two symbols preceding the AGC symbol are the start time of CP-E transmission, T=2. Furthermore, it is based on the defined symbol length L of the SCS. SCS (Unit is time in microseconds), T L SCS The resulting product is used as the switching time from SL RX to SL TX.

[0082] In some examples, the configuration time of CP-E is determined based on the switching time from SL RX to SL TX, the LBT time, and the TA. Specifically, this may include subtracting the LBT time and TA from the switching time from SL RX to SL TX to obtain the configuration time of CP-E.

[0083] For example, such as Figure 4 As shown, the switching time from SL RX to SL TX is T symbols (T L SCS This may include LBT time T. LBT The configuration time for TA and CP-E is determined by TCP-E. For the initial stage of SL TX, based on network configuration or the actual pre-configuration of the terminal equipment, the LBT form used by the terminal equipment is explicitly determined, and the LBT time is determined. For sidelink transmission, its transmission TA is specified. The corresponding SCS and the corresponding T symbols are also determined as the handover time from SL RX to SL TX. The actual terminal CP-E configuration time can be shown in Formula 1: T CP-E =T L SCS -T LBT -TA (Formula 1) In Formula 1, T represents the T symbols determined by the terminal device; L SCS Indicates the symbol length (in microseconds) based on the explicit SCS; T LBT This indicates the LBT time determined by the terminal device; TA indicates the timing advance determined by the terminal device.

[0084] Step 302: Determine the first configuration information based on the CP-E configuration time.

[0085] The first configuration information can be used to configure the first power transient cycle of the transmitting terminal device at the start of the SL TX phase.

[0086] In some examples, the first power transient cycle is configured within the CP-E configuration time when the configuration time of the CP-E is greater than or equal to the configuration time of the first power transient cycle.

[0087] For example, taking the first power transient cycle as having a duration of 15µs, if the calculated CP-E configuration time T... CP-E Greater than or equal to 15us, such as Figure 5 As shown, the first power transient cycle of 15us can be configured in the configuration time of CP-E, that is, the entire power switching from SL RX to SL TX is placed in CP-E, which can leave enough LBT time for the terminal device to sense.

[0088] In some examples, when the configuration time of the CP-E is less than the length of the first power transient cycle, the first power transient cycle includes a first part and a second part. The first part covers the configuration time of the CP-E, and the second part is configured within a first time period, wherein the first time period is the time period in which the LBT time and TA are located.

[0089] For example, taking the first power transient cycle as having a duration of 15µs, if the calculated CP-E configuration time T... CP-E Less than 15us, such as Figure 6 As shown, the first power transient cycle of 15µs can cover the entire CP-E, while the excess 15µs-T CP-E The time can be placed outside of the CP-E time, occupying a portion of the T time. LBT +TA time, that is, to maximize the use of CP-E configuration time and reduce the impact on LBT time.

[0090] In some examples, after determining the first configuration information, the method of this embodiment may further include: the transmitting terminal device performing a power switch from SL RX to SL TX according to the time corresponding to the first configuration information.

[0091] For example, the power of the terminal device in SL RX is different from that in SL TX. In this embodiment, the transmitting terminal device can switch the power from SL RX to SL TX according to the time corresponding to the first configuration information to meet the power requirements of the signal to be transmitted next.

[0092] Step 303: Determine the second configuration information based on the GP in the transmission frame of the side link.

[0093] The second configuration information is used to configure the second power transient period of the transmitting terminal device during the SL TX end phase. For ease of description, the power transient period during the SL TX end phase can be referred to as the second power transient period. The SL TX end phase is the time phase corresponding to the transmitting terminal device switching from SL TX to SL RX.

[0094] In some examples, the second power transient cycle can be configured in the GP. For example... Figure 2 The frame structure of the sidelink transmission frame described in the embodiment has a last symbol, GP, which is a blank symbol. This allows the second power transient cycle at the end of the SL TX phase to be configured in GP. This allows sufficient time to be reserved for subsequent LBT after the SL TX ends.

[0095] For example, taking a second power transient cycle with a duration of 10µs as an example, Figure 7 As shown, given that the last symbol of SL-U is GP, even when the maximum SCS=60kHz, the duration of one symbol is 18.5us, which can cover the 10us second power transient cycle. Therefore, the entire second power transient cycle can be placed in the last GP, which can reserve enough time after the end of SL TX for subsequent LBT.

[0096] In some examples, the method of this embodiment may further include: switching power from SLTX to SLRX according to the time corresponding to the second configuration information. For example, if the power of the terminal device in SLTX is different from that in SLRX, the transmitting terminal device in this embodiment may switch power from SLTX to SLRX according to the time corresponding to the second configuration information to meet the power requirements of the received signal.

[0097] By applying the communication configuration method provided in this embodiment, first configuration information is determined based on the configuration time of CP-E. This first configuration information can be used to configure the first power transient cycle of the terminal device at the beginning of SL TX; and based on the GP in the transmission frame of the side link, the entire second power transient cycle is placed in the GP to ensure minimal impact on LBT time and ensure LBT success. This embodiment provides a configuration scheme for the ON / OFF time mask of SL-U to ensure that the terminal device retains sufficient LBT time under sufficient switching time and does not affect the data transmission of the side link.

[0098] Figure 8A flowchart illustrating a communication configuration method according to an embodiment of this application is shown. This method is applied to the receiving terminal device side (e.g., Figure 1 The receiving terminal device 12) in the process may perform the following steps.

[0099] Step 401: Determine the third configuration information based on the GP in the transmission frame of the side link.

[0100] The third configuration information is used to configure the third power transient period of the receiving terminal device during the SL TX end phase. The SL TX end phase is the time period corresponding to the receiving terminal device switching from SL TX to SL RX.

[0101] In some examples, a third power transient cycle can be configured in the GP. For example... Figure 2 The frame structure of the sidelink transmission frame described in the embodiment has a last symbol, GP, which is a blank symbol. This allows the third power transient cycle at the end of the SL TX phase to be configured in GP. This allows sufficient time to be reserved for subsequent LBT after the SL TX ends.

[0102] For example, taking a third power transient cycle with a duration of 10µs as an example, such as Figure 9 As shown, given that the last symbol of SL-U is GP, even when the maximum SCS=60kHz, the duration of one symbol is 18.5us, which can cover the 10us third power transient cycle. Therefore, the entire third power transient cycle can be placed in the last GP, which can reserve enough time after the end of SL TX for subsequent LBT.

[0103] In some examples, the method of this embodiment may further include: the receiving terminal device switching power from SL TX to SL RX according to the time corresponding to the third configuration information. For example, if the power of the terminal device in SL TX is different from that in SL RX, the receiving terminal device in this embodiment may switch power from SL TX to SL RX according to the time corresponding to the third configuration information to meet the power requirements of the received signal.

[0104] By applying the communication configuration method provided in this embodiment, a configuration scheme for the ON / OFF time mask of SL-U is provided to ensure that the terminal device retains sufficient LBT time under the premise of sufficient switching time, and does not affect the data transmission of the side link.

[0105] Figure 10 A flowchart illustrating a communication configuration method according to an embodiment of this application is shown. Based on Figure 8 The illustrated embodiment, as Figure 10 As shown, this method is applied to the receiving terminal device side and may include the following steps.

[0106] Step 501: Determine the third configuration information based on the GP in the transmission frame of the side link.

[0107] The third configuration information is used to configure the third power transient cycle of the receiving terminal device during the SL TX end phase.

[0108] The receiving terminal device switches power from SL TX to SL RX according to the time corresponding to the third configuration information. Subsequent signal reception is performed at the switched power, i.e., the SL RX process is executed. When SL RX ends and SL TX begins, a corresponding fourth power transient period needs to be configured, specifically by executing steps 502 to 503. The SL TX beginning phase is the time period corresponding to the receiving terminal device switching from SL RX to SL TX.

[0109] Step 502: Determine the CP-E configuration time.

[0110] This embodiment can calculate the CP-E configuration time according to the actual situation in order to determine how to place the fourth power transient cycle of the SL TX start phase within the CP-E configuration time.

[0111] In some examples, step 502 may specifically include: determining the switching time from SL RX to SL TX; and determining the LBT time and TA; and determining the CP-E configuration time based on the switching time from SL RX to SL TX, the LBT time, and the TA.

[0112] For example, the switching time between SL RX and SL TX of the terminal device can be determined; and based on the actual situation of network configuration or pre-configuration of the terminal device, the LBT form used by the terminal device can be clearly defined, and the corresponding LBT time can be determined. For side link transmission, the TA of its transmission can be clearly defined accordingly. Based on these time parameters, the configuration time of CP-E can be accurately determined.

[0113] In some examples, the process of determining the handover time from SL RX to SL TX may specifically include: determining a second number of symbols required for the handover from SL RX to SL TX; and determining the symbol length of the SCS; multiplying the second number of symbols by the symbol length of the SCS to obtain the handover time of the terminal device from SL RX to SL TX.

[0114] In some examples, when the first symbol of the AGC symbol is the start time point of CP-E transmission, the second quantity is 1; when the first two symbols of the AGC symbol are the start time points of CP-E transmission, the second quantity is 2.

[0115] This embodiment can determine the T symbols required for switching from SL RX to SL TX based on the actual CP-E configuration of SL-U. When the first symbol preceding the AGC symbol is the start time of CP-E transmission, T=1; when the first two symbols preceding the AGC symbol are the start time of CP-E transmission, T=2. Furthermore, it is based on the defined symbol length L of the SCS. SCS (Unit is time in microseconds), T L SCS The resulting product is used as the switching time from SL RX to SL TX.

[0116] In some examples, the configuration time of CP-E is determined based on the switching time from SL RX to SL TX, the LBT time, and the TA. Specifically, this may involve subtracting the LBT time and TA from the switching time from SL RX to SL TX to obtain the configuration time of CP-E. See the corresponding description in Formula 1 above for details, which will not be repeated here.

[0117] Step 503: Determine the fourth configuration information based on the CP-E configuration time.

[0118] The fourth configuration information is used to configure the fourth power transient cycle of the receiving terminal device at the start of the SL TX phase.

[0119] In some examples, the fourth power transient cycle is configured within the CP-E configuration time when the configuration time of the CP-E is greater than or equal to the configuration time of the fourth power transient cycle.

[0120] For example, taking the fourth power transient cycle as having a duration of 15µs, if the calculated CP-E configuration time T... CP-E Greater than or equal to 15us, such as Figure 11 As shown, the fourth power transient cycle of 15µs can be configured in the configuration time of CP-E, that is, the entire power switching from SL RX to SL TX is placed in CP-E, which can leave enough LBT time for the receiving terminal equipment to sense.

[0121] In some examples, when the configuration time of CP-E is less than the length of the fourth power transient cycle, the fourth power transient cycle includes a first part and a second part. The first part covers the configuration time of CP-E, and the second part is configured within a second time period, where the second time period is the time period in which LBT and TA are located.

[0122] For example, taking the fourth power transient cycle as having a duration of 15µs, if the calculated CP-E configuration time T... CP-E Less than 15us, such as Figure 12 As shown, the fourth power transient cycle of 15µs can cover the entire CP-E, while the excess 15µs-T CP-E The time can be placed outside of the CP-E time, occupying a portion of the T time. LBT +TA time, that is, to maximize the use of CP-E configuration time and reduce the impact on LBT time.

[0123] In some examples, after determining the fourth configuration information, the method of this embodiment may further include: the receiving terminal device switching power from SL RX to SL TX according to the time corresponding to the fourth configuration information. For example, if the power of the terminal device in SL RX is different from that in SL TX, the receiving terminal device in this embodiment may switch power from SL RX to SL TX according to the time corresponding to the fourth configuration information to meet the power requirements of the subsequent transmitted signal.

[0124] This embodiment provides a configuration scheme for the ON / OFF time mask of SL-U to ensure that the terminal device retains sufficient LBT time while having sufficient switching time, and does not affect the data transmission of the side link.
