The communication configuration method and device provided by the application are described in detail below with reference to the accompanying drawings.

Fig. 2 shows a flow diagram of a communication configuration method according to an embodiment of the application. As shown in fig. 2, the method applied to the transmitting terminal device side (e.g., the transmitting terminal device 11 in fig. 1) may include the following steps.

Step 201, determining first configuration information according to the configuration time of the CP-E.

The first configuration information is used to configure a first power transient period of the transmitting terminal device in the SL TX start phase, and for convenience of description, the power transient period (transient period) of the SL TX start phase may be referred to as the first power transient period. The SL TX start phase is a time phase corresponding to the switching of the transmitting terminal device from SL RX to SL TX. The first power transient period is used to determine a time corresponding to a power switch from SL RX to SL TX, according to which the transmitting terminal device will perform the power switch from SL RX to SL TX.

The frame structure of the transmission frame of the side link may employ a slot structure of an orthogonal frequency division multiplexing (Orthogonal Frequency Division Multiplexing, OFDM) symbol as follows.

The first symbol in the frame structure of the transmission frame of the side link is Automatic Gain Control (AGC), and the last symbol is Guard Period (GP). The middle symbols may correspond to signals such as physical direct control channel (Physical Sidelink Control Channel, PSCCH)/physical direct shared channel (Physical Sidelink Control Channel, PSSCH), and physical direct feedback channel (Physical Sidelink Feedback Channel, PSFCH).

Based on the frame structure of the transmission frame of the side uplink, the first L symbols of the AGC symbols can be determined as the starting transmission time point of the CP-E according to the configuration situation of the CP-E of the SL-U. L can be a positive integer such as 1,2, etc. The embodiment can carry out new configuration on the on/offtimemask of the SL-U according to the configuration condition of the CP-E of the SL-U and/or the frame structure above so as to ensure that the terminal equipment reserves enough LBT time and does not influence the data transmission of the side uplink on the premise of enough switching time. The configuration information of the first power transient period of the transmitting terminal device in the SL TX start phase, that is, the first configuration information, may be specifically determined according to the configuration time of the CP-E.

The communication configuration method provided by the embodiment provides a configuration scheme of an ON/OFF time mask of SL-U. So as to ensure that the terminal equipment reserves enough LBT time on the premise of enough switching time and does not influence the data transmission of the side uplink.

Fig. 3 shows a flow diagram of a communication configuration method according to an embodiment of the application. Based on the embodiment shown in fig. 2, as shown in fig. 3, the method is applied to the side of the transmitting terminal device for execution, and may include the following steps.

Step 301, determining the configuration time of the CP-E.

The present embodiment may calculate the CP-E configuration time according to the actual situation to determine how to place the first power transient period of the SL TX start phase within the CP-E configuration time.

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

For example, determining a time for a terminal device to switch from SL RX to SL TX; and according to the actual situation of network configuration or terminal equipment pre-configuration, the terminal equipment can determine the LBT form used specifically, further determine the corresponding LBT time, and for the side uplink transmission, determine the TA of the transmission correspondingly, and accurately determine the configuration time of the CP-E according to the time parameters.

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

In some examples, the first number may be 1 when the first 1 symbol of the AGC symbols is the starting transmission time point of CP-E; and the first number may be 2 when the first 2 symbols of the AGC symbol are the starting transmission time points of CP-E.

For example, the CP-E configuration of SL-U can be divided into the following two cases:

case 1: the previous symbol configured as the AGC symbol serves as the starting transmission time point of the CP-E.

Case 2: when scs=15 kHz, the first 1 symbol configured as AGC symbol is taken as the starting transmission time point of CP-E; the first 2 symbols configured as AGC symbols are taken as the starting transmission time point of CP-E when scs=30 kHz and 60 kHz.

This embodiment is based on the CP-E actual configuration of SL-UIn case, T symbols required for switching from SL RX to SL TX may be determined, t=1 when the first 1 symbol of the AGC symbol is the starting transmission time point of CP-E; when the first 2 symbols of the AGC symbol are the starting transmission time points of CP-E, t=2. And based on the symbol length L of explicit SCS _SCS (in time us), T.times.L _SCS The resulting product is taken as the switching time from SL RX to SL TX.

In some examples, determining the CP-E configuration time from the switching time from SL RX to SL TX, LBT time, and TA may include: the LBT time and TA are subtracted from the switching time from SL RX to SL TX to get the CP-E configuration time.

For example, as shown in fig. 4, the switching time from SL RX to SL TX is T symbols (t×l _SCS ) This may include LBT time T _LBT Configuration time TCP-E for TA and CP-E. For the starting stage of SL TX, determining the LBT time according to the actual situation of network configuration or terminal equipment pre-configuration, and the LBT form used by the terminal equipment definitely. For a side-link transmission, its transmission TA is explicit. And determines the corresponding SCS, and the corresponding T symbols as the time to switch from SL RX to SL TX. The actual time for the configuration of the terminal CP-E may be as shown in equation one:

T _CP-E ＝T*L _SCS -T _LBT TA (equation one)

In the formula I, T represents T symbols determined by the terminal equipment; l (L) _SCS Represents symbol length (in time us) based on explicit SCS; t (T) _LBT Representing the LBT time determined by the terminal equipment; the TA represents the timing advance determined by the terminal device.

Step 302, determining first configuration information according to the configuration time of the CP-E.

The first configuration information may be used to configure the transmitting terminal device for a first power transient period during a start phase of the SL TX.

In some examples, the first power transient period is configured in the configuration time of the CP-E when the time length of the configuration time of the CP-E is greater than or equal to the time length of the first power transient period.

For example, with a first workFor example, if the time length of the rate transient period is 15us, the calculated configuration time T of the CP-E _CP-E Greater than or equal to 15us, as shown in fig. 5, the first power transient period of 15us may be configured in the CP-E configuration time, i.e., the entire power switch from SL RX to SL TX may be placed in CP-E, thus leaving enough LBT time for the terminal device to perceive (send).

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

For example, taking the first power transient period with a time length of 15us as an example, if the calculated configuration time T of CP-E _CP-E Less than 15us, as shown in FIG. 6, the first power transient period of 15us may cover the entire CP-E, while the excess 15us-T _CP-E Optionally placed outside the CP-E time, occupying a portion of T _LBT The +TA time, i.e., the configuration time of CP-E is maximally utilized, reduces the impact on LBT time.

In some examples, after determining the first configuration information, the method of the embodiment may further include: the transmitting terminal device performs power switching from SL RX to SL TX according to the time corresponding to the first configuration information.

For example, the power of the terminal device at the SL RX is different from the power at the SL TX, and the transmitting terminal device of the present embodiment may perform power switching from the SL RX to the SL TX according to the time corresponding to the first configuration information, so as to meet the power requirement of the signal to be transmitted next.

Step 303, determining second configuration information according to GP in the transmission frame of the side uplink.

The second configuration information is used to configure the second power transient period of the transmitting terminal device in the SL TX end phase, and for convenience of description, the power transient period (transient period) of the SL TX end phase may be referred to as the second power transient period. The SL TX end phase is a time phase corresponding to the switching of the transmitting terminal device from SL TX to SL RX.

In some examples, the second power transient period may be configured in the GP. As in the frame structure of the transmission frame of the side-link described in the embodiment of fig. 2, the last symbol is GP, which is a blank symbol, and the second power transient period of the SL TX end phase may be further configured in GP. This allows enough time after the end of the SL TX to be reserved for subsequent LBT.

For example, taking the time length of the second power transient period as 10us as an example, as shown in fig. 7, considering that the last symbol of SL-U is GP, even if the time of one symbol is 18.5us at the maximum scs=60 kHz, the second power transient period of 10us can be covered, so the entire second power transient period can be placed in the last GP, so that a sufficient time after the end of SL TX can be reserved for the subsequent LBT.

In some examples, the method of the present embodiment may further include: and performing power switching from SL TX to SL RX according to the time corresponding to the second configuration information. For example, the power of the terminal device at the SL TX is different from the power at the SL RX, and the transmitting terminal device of the present embodiment may perform power switching from the SL TX to the SL RX according to the time corresponding to the second configuration information, so as to meet the power requirement of the next received signal.

By applying the communication configuration method provided by the embodiment, according to the configuration time of the CP-E, first configuration information is determined, and the first configuration information can be used for configuring a first power transient period of the terminal device in the SL TX start phase; and according to GP in the transmission frame of the side link, placing the whole second power transient period in the GP to ensure that the influence on LBT time is minimum and ensure the success of LBT. The present embodiment provides a configuration scheme for ON/OFF time mask of SL-U to ensure that the terminal device reserves enough LBT time without affecting data transmission of side links ON the premise of having enough switching time.

Fig. 8 shows a flow diagram of a communication configuration method according to an embodiment of the application. The method is performed on the receiving terminal device side (e.g., receiving terminal device 12 in fig. 1), and may include the following steps.

Step 401, determining third configuration information according to GP in the transmission frame of the side uplink.

The third configuration information is used to configure a third power transient period (transient period) of the receiving terminal device at the end of the SL TX. The SL TX end phase is a time phase corresponding to the switching of the receiving terminal device from SL TX to SL RX.

In some examples, the third power transient period may be configured in the GP. As in the frame structure of the transmission frame of the side-link described in the embodiment of fig. 2, the last symbol is GP, which is a blank symbol, and thus the third power transient period of the SL TX end phase may be configured in GP. This allows enough time after the end of the SL TX to be reserved for subsequent LBT.

For example, taking the time length of the third power transient period as 10us as an example, as shown in fig. 9, considering that the last symbol of SL-U is GP, even if the time of one symbol is 18.5us at the maximum scs=60 kHz, the third power transient period of 10us can be covered, so the entire third power transient period can be placed in the last GP, so that a sufficient time after the end of SL TX can be reserved for the subsequent LBT.

In some examples, the method of the present embodiment may further include: the receiving terminal device performs power switching from the SL TX to the SL RX according to the time corresponding to the third configuration information. For example, the power of the terminal device at the SL TX is different from the power at the SL RX, and the receiving terminal device of the present embodiment may perform power switching from the SL TX to the SL RX according to the time corresponding to the third configuration information, so as to meet the power requirement of the next received signal.

By applying the communication configuration method provided by the embodiment, a configuration scheme of an ON/OFF time mask of the SL-U is provided, so that the terminal equipment is ensured to reserve enough LBT time ON the premise of enough switching time, and data transmission of a side uplink is not affected.

Fig. 10 shows a flow diagram of a communication configuration method according to an embodiment of the application. Based on the embodiment shown in fig. 8, as shown in fig. 10, the method is applied to the receiving terminal device side for execution, and may include the following steps.

Step 501, determining third configuration information according to GP in the transmission frame of the side uplink.

The third configuration information is used to configure a third power transient period of the receiving terminal device at the end of the SL TX phase.

The receiving terminal device performs power switching from the SL TX to the SL RX according to the time corresponding to the third configuration information. The signal reception is then performed at the switched power, i.e. the SL RX procedure is performed. When the SL RX ends and during the SL TX start phase, a corresponding fourth power transient period (transient period) needs to be configured, and the process shown in steps 502 to 503 may be specifically performed. The SL TX start phase is a time phase corresponding to the switching of the receiving terminal device from SL RX to SL TX.

Step 502, determining the configuration time of the CP-E.

The present embodiment may calculate the CP-E configuration time according to the actual situation to determine how to place the fourth power transient period of the SL TX start phase within the CP-E configuration time.

In some examples, step 502 may specifically include: determining a switching time from SL RX to SL TX; and, determining LBT time and TA; the configuration time of the CP-E is determined according to the switching time from the SL RX to the SL TX, the LBT time, and the TA.

For example, determining a time for a terminal device to switch from SL RX to SL TX; and according to the actual situation of network configuration or terminal equipment pre-configuration, the terminal equipment can determine the LBT form used specifically, further determine the corresponding LBT time, and for the side uplink transmission, determine the TA of the transmission correspondingly, and accurately determine the configuration time of the CP-E according to the time parameters.

In some examples, the process of determining the switching time from SL RX to SL TX may specifically include: determining a second number of symbols required for switching between SL RX to SL TX; and, determining the symbol length of SCS; multiplying the second number of symbols by the symbol length of the SCS, resulting in a switching time of the terminal device from SL RX to SL TX.

In some examples, the second number is 1 when the first 1 symbol of the AGC symbols is the starting transmission time point of CP-E; the second number is 2 when the first 2 symbols of the AGC symbols are the starting transmission time points of CP-E.

In this embodiment, according to the actual configuration of CP-E of SL-U, T symbols required for switching from SL RX to SL TX may be determined, where t=1 when the first 1 symbols of the AGC symbols are the starting transmission time point of CP-E; when the first 2 symbols of the AGC symbol are the starting transmission time points of CP-E, t=2. And based on the symbol length L of explicit SCS _SCS (in time us), T.times.L _SCS The resulting product is taken as the switching time from SL RX to SL TX.

In some examples, determining the CP-E configuration time from the switching time from SL RX to SL TX, LBT time, and TA may include: the LBT time and TA are subtracted from the switching time from SL RX to SL TX to get the CP-E configuration time. See the corresponding description in the above formula one, and will not be repeated here.

Step 503, determining fourth configuration information according to the configuration time of the CP-E.

The fourth configuration information is used to configure the receiving terminal device for a fourth power transient period during the SL TX start phase.

In some examples, the fourth power transient period is configured in the configuration time of the CP-E when the length of time of the configuration time of the CP-E is greater than or equal to the length of time of the fourth power transient period.

For example, taking the fourth power transient period with a time length of 15us as an example, if the calculated configuration time T of CP-E _CP-E Greater than or equal to 15us, as shown in fig. 11, a fourth power transient period of 15us may be configured in the CP-E configuration time, i.e., the entire power switch from SL RX to SL TX may be placed in CP-E, thus allowing sufficient LBT time for the receiving terminal device to perceive.

In some examples, when the length of time of the configuration time of the CP-E is less than the length of time of the fourth power transient period, the fourth power transient period includes a first portion and a second portion, the first portion covering the configuration time of the CP-E, the second portion being configured within a second time period, wherein the second time period is a time period in which the LBT time and the TA are located.

For example, taking the fourth power transient period with a time length of 15us as an example, if the calculated configuration time T of CP-E _CP-E Less than 15us, as shown in FIG. 12, a fourth power transient period of 15us may cover the entire CP-E, while the excess 15us-T _CP-E Optionally placed outside the CP-E time, occupying a portion of T _LBT The +TA time, i.e., the configuration time of CP-E is maximally utilized, reduces the impact on LBT time.

In some examples, after determining the fourth configuration information, the method of the present embodiment may further include: the receiving terminal device performs power switching from SL RX to SL TX according to the time corresponding to the fourth configuration information. For example, the power of the terminal device at the SL RX is different from the power at the SL TX, and the receiving terminal device of the present embodiment may perform power switching from the SL RX to the SL TX according to the time corresponding to the fourth configuration information, so as to meet the power requirement of the signal to be transmitted next.

The present embodiment provides a configuration scheme for ON/OFF time mask of SL-U to ensure that the terminal device reserves enough LBT time without affecting data transmission of side links ON the premise of having enough switching time.
