technical field

The present application relates to the field of communication technologies, and in particular, to a signal transmission method, an apparatus, a terminal device, a network device, and a storage medium.

Background technique

In the existing communication system, the reference signal configured by the base station for the terminal does not always exist, and the reference signal in some configurations can only be sent after being triggered (trigger) or activated (activated). If the base station configures a certain reference signal for the terminal and sends the trigger or activation signaling of the reference signal to the terminal, after the terminal receives the signaling, it needs to trigger and send the reference signal according to the predefined timing relationship or the base station instruction The reference signal triggers and sends the timing relationship signaling to determine the sending moment of the reference signal.

For example, for the triggering of the aperiodic sounding reference signal SRS resources in the 3GPPNR system of the 3rd Generation Partnership Project New Air Interface, the triggering method and the transmission timing regulation of the aperiodic SRS resources restrict the base station from sending the downlink control for triggering the aperiodic SRS resources.

Detailed ways

The technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the drawings in the embodiments of the present application. Obviously, the described embodiments are only a part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present application.

As mentioned in the Background section, in the existing communication system, the reference signal configured by the base station for the terminal does not always exist. It can only be sent after being triggered (trigger) or activated (activate). If the base station configures a certain reference signal for the terminal and sends the trigger or activation signaling of the reference signal to the terminal, after the terminal receives the signaling, it needs to trigger and send the reference signal according to the predefined timing relationship or the base station instruction The reference signal triggers and sends the timing relationship signaling to determine the sending moment of the reference signal.

Taking the reference signal as the SRS as an example, in the ^3rd Generation Partnership Project New Radio (3GPP NR) system, the base station sends the terminal equipment UE (User Equipment) configure aperiodic SRS (or Channel State Information Reference Signal CSI-RS (Channel State Information Reference Signal)) resource sets and aperiodic SRS (/CSI-RS) resources, through the SRS request field in the DCI signaling ( /CSI request field) triggers the transmission of aperiodic SRS (/CSI-RS) resources. When configuring the aperiodic SRS (/CSI-RS) resource set through RRC, the RRC signaling slotOffset (/aperiodicTriggeringOffset) is used to configure the SRS (/CSI-RS) in the aperiodic SRS (/CSI-RS) resource set The trigger offset value for the resource. When the base station triggers an aperiodic SRS (/CSI-RS) resource set through the SRS request field (/CSI reporting field/CSI request field) in the DCI at slot n, the SRS (/CSI-RS) All SRS (/CSI-RS) resources in the resource set are in time slots

Send, where k is the trigger slot offset value corresponding to slotOffset (/aperiodicTriggeringOffset), and μ _SRS and μ _PDCCH are the subcarrier spacing values of the triggered SRS and the PDCCH carrying the trigger command, respectively.

Since the configuration of the RRC signaling is semi-static, configuring the trigger offset value of the aperiodic SRS through the RRC signaling makes the triggering of the SRS inflexible. In addition, in the TDD mode, if the time slot n+n _offset is a downlink slot (/uplink slot), then the time slot n+n _offset cannot perform SRS (/CSI-RS) transmission, and the UE will no longer perform the SRS (/ CSI-RS) transmission. In order to prevent SRS (/CSI-RS) from being unable to transmit, this will limit the time domain position where the base station sends DCI, thereby reducing the flexibility of triggering SRS (/CSI-RS) transmission through DCI. Figure 1 shows that the configuration of uplink and downlink time slots is a configuration mode of DDFUU every five time slots (where D represents downlink time slot, U represents uplink time slot, and F represents flexible time slot with both uplink symbols and downlink symbols Slots), complete the transmission of PDSCH triggering aperiodic SRS and all possible positions of PDCCH and SRS when aperiodic SRS is transmitted within five time slots. Each row represents a transmission position of a PDCCH and an SRS under an SRS time slot offset value, and each vertical column represents a time slot. It can be seen from Figure 1 that when the trigger slot offset value is 1, the PDCCH used to trigger aperiodic SRS can only be transmitted in slot 1 or slot 2, and cannot be transmitted in other time slots, and SRS can only be transmitted in slot 2 and slot 3 transfers. It can be seen that the triggering method of the SRS resources and the transmission timing regulations of the aperiodic SRS resources limit the time domain position of the base station to send the downlink control information DCI that triggers the aperiodic SRS resources, which leads to insufficient triggering and transmission of the aperiodic SRS resources.

The present application will be specifically described below.

As shown in FIG. 2, a flowchart of steps of a signal transmission method applied to a terminal device provided by an embodiment of the present application, the method includes the following steps:

Step 101: Receive trigger signaling for trigger signal transmission or reception;

In this embodiment, it can be understood that the uplink signal is sent, and the downlink signal is received.

Step 102: Determine the transmission position of the signal from the transmission opportunity of the signal according to the trigger signaling, and/or determine the transmission opportunity of the signal according to the trigger signaling, and determine the transmission opportunity of the signal from the transmission opportunity of the signal. opportunity to determine the transmission location of the signal.

Optionally, after the transmission position of the signal is determined, the signal is transmitted according to the transmission position. Optionally, the transmitting the signal according to the transmission location includes: transmitting the signal at the transmission location. Optionally, the transmitting the signal according to the transmission position includes: transmitting the signal on some symbols of the transmission position.

In this embodiment, it can be understood that a network device such as a base station sends a trigger signal to the terminal device UE to transmit or receive a trigger signal, and after receiving the trigger signal, the UE, according to the trigger signal, transmits or receives the trigger signal from the signal. The transmission position of the signal is determined in the transmission opportunity. In this embodiment, the signal has n transmission opportunities (n>1) corresponding to this trigger. The UE takes the transmission opportunity that meets the preset condition as the transmission position of the signal. In addition, it should be noted that when there is no transmission opportunity satisfying the preset condition, the UE does not transmit or receive the signal.

In this embodiment, it can be understood that, after determining the transmission position of the signal, the terminal device UE sends the signal at the transmission position or receives the signal at the transmission position. When the signal is an uplink signal, the UE sends the signal at the transmission location. When the signal is a downlink signal, the UE receives the signal at the transmission location.

In this embodiment, it can be understood that the transmission opportunity (or referred to as the transmission opportunity) of the signal can be determined according to the trigger signaling in various ways, for example, according to the set of signal resources used by the network device to trigger the signal for the trigger signaling Indicated slot offset signaling determines the transmission opportunity, or determines the transmission opportunity according to a preset slot offset value or a slot offset value determined according to a preset rule, etc., which will be further explained below. Way. A transmission opportunity of a signal can be understood as a set of alternative time domain resources or a set of alternative time-frequency resources corresponding to the signal. A transmission opportunity can be a resource within a time slot, or a resource spanning multiple time slots. Taking the signal as an SRS as an example, assuming that the SRS resource corresponding to the SRS is configured to transmit the last two OFDM symbols of a time slot, each of its transmission opportunities is the last two OFDM symbols of a time slot. For another example, assuming that the SRS resource corresponding to one SRS is configured so that one transmission opportunity is 2 OFDM symbols, there may be multiple transmission opportunities corresponding to the SRS in a time slot, and each transmission opportunity includes 2 OFDM symbols. It is also possible for a transmission opportunity of t to span two adjacent time slots. This specification mainly takes one transmission opportunity in one time slot and one transmission opportunity in one time slot as an example to describe the method and device of the present invention. It should be understood that the method can be extended to one transmission opportunity spanning multiple slot, and/or multiple transmission opportunities within a slot. In this embodiment, when one transmission opportunity in one time slot is taken as an example, the transmission position of the signal can be determined from the multiple time slots corresponding to the signal according to the trigger signaling. The method determines whether a time slot can be the time slot where the transmission position of the signal is located. For example, if a time slot includes at least one uplink or flexible symbol configured by high-level signaling, the time slot is determined to meet the transmission conditions. time slot, or if the uplink and/or flexible symbols included in a time slot include all time domain symbols in which the first signal resource is configured in a time slot, then determine that the time slot is a time that satisfies the transmission condition These methods will be further described below; it can be known from the above description that the transmission opportunity of the signal can be determined according to the trigger signaling, and then the transmission position of the signal can be determined from the transmission opportunity.

It should be noted that this embodiment is applicable to aperiodic uplink signals (such as sounding reference signal SRS), aperiodic downlink signals (such as channel state information reference signal CSI-RS (Channel State Information Reference Signal), channel state information interference Measure CSI-IM (Channel State Information Interference Measurement) reference signal, etc.), semi-persistent uplink signal, semi-persistent downlink signal, etc. To make the description more intuitive, the subsequent embodiments of the present application will be described by using an aperiodic SRS. It can be seen that this embodiment can solve the problem of inflexibility in triggering and sending of aperiodic signal resources in a wireless communication system.

The signal transmission method provided by the embodiment of the present application receives trigger signaling for triggering signal transmission or reception, and then determines the transmission position of the signal from multiple transmission opportunities of the signal according to the trigger signaling. It can be seen that the present application The embodiment increases signal transmission opportunities and increases the flexibility of signal resource scheduling and transmission.

Based on the content of the foregoing embodiment, in this embodiment, the transmission position of the signal is determined from the transmission opportunity of the signal according to the trigger signaling, and/or the signal is determined according to the trigger signaling the transmission opportunity, and determine the transmission position of the signal from the transmission opportunity, including:

determining the transmission position of the signal according to one or more of the transmission opportunities that satisfy the transmission conditions;

And/or, arbitrarily selecting one transmission opportunity from the transmission opportunities as the transmission position of the signal.

An example of determining the transmission position of the signal according to one or more of the transmission opportunities that satisfy the transmission conditions is:

One or more transmission opportunities that satisfy the transmission condition among the transmission opportunities are used as the transmission position of the signal.

Another example of determining the transmission position of the signal according to one or more of the transmission opportunities satisfying the transmission conditions is:

In one or more of the transmission opportunities that satisfy the transmission condition, the transmission position of the signal is further determined in combination with some other information. For example, determine whether there are other signals with a higher priority than the signal in the one or more transmission opportunities, and if there are other signals with a higher priority than the signal on some symbols, these symbols are not the signal the transmission position of the signal, and other symbols in the one or more transmission opportunities are the transmission position of the signal.

Based on the content of the foregoing embodiment, in this embodiment, according to the trigger signaling, the transmission position of the signal is determined from the transmission opportunity of the signal, including:

It is judged whether one or more of the multiple transmission opportunities satisfy the transmission condition, until N transmission opportunities that satisfy the transmission condition are determined or until the termination condition is reached, where N is an integer greater than or equal to 1.

In this embodiment, according to the trigger signaling, one or more of the multiple transmission opportunities are sequentially judged whether the transmission conditions are met, until N transmission opportunities satisfying the transmission conditions are determined or until the Termination condition, N is an integer greater than or equal to 1. It should be noted that the order here is not necessarily to judge all the transmission opportunities, but to judge some or all of the transmission opportunities. After the transmission opportunities that satisfy the transmission conditions are determined, the transmission position of the signal may be further determined according to the transmission opportunities that satisfy the transmission conditions. For example, the transmission positions of the signals are the determined transmission opportunities that satisfy the transmission conditions. For another example, the transmission position of the signal is that there are no symbols of other signals with a higher priority than the signal in these transmission opportunities that satisfy the transmission conditions.

In this embodiment, the value of N can be set as required, for example, optional, N=1; optional, N=2; optional, N is a value indicated by the base station; optional, N is a predefined numerical value. For example, it is the value agreed by the agreement. Optionally, N is the value reported by the terminal device.

Based on the content of the above embodiment, in this embodiment, it is determined whether one or more of the multiple transmission opportunities satisfy the transmission condition according to the trigger signaling, until it is determined that N satisfy the transmission condition transmission opportunities or until termination conditions are met, including:

Among them, the initial value of k is 1.

In this embodiment, it is given to judge whether one or more of the multiple transmission opportunities meet the transmission condition according to the trigger signaling, until N transmission opportunities that meet the transmission condition are determined or The specific implementation process until the termination condition is reached, according to the above description, this embodiment judges whether each transmission opportunity satisfies the transmission condition in turn, if so, continues to judge whether N transmission opportunities are determined, if so, stop, otherwise continue to judge Until N transmission opportunities are determined. In addition, when the termination condition is satisfied, the judgment of whether or not the transmission condition is satisfied will no longer be made. After the transmission opportunities that satisfy the transmission conditions are determined, the transmission position of the signal may be further determined according to the transmission opportunities that satisfy the transmission conditions. For example, the transmission positions of the signals are the determined transmission opportunities that satisfy the transmission conditions. For another example, the transmission position of the signal is that there are no symbols of other signals with a higher priority than the signal in these transmission opportunities that satisfy the transmission conditions.

Based on the content of the foregoing embodiment, in this embodiment, whether one or more of the multiple transmission opportunities satisfies the transmission condition is determined according to at least one of the following:

Up and down pattern configuration;

the time interval between the trigger signaling and the signal transmission;

the priority of the signal; or,

In this embodiment, it can be configured according to ① uplink and downlink patterns ② time interval between trigger signaling and signal transmission ③ time window requirements for trigger signaling transmission and signal transmission ④ signal priority ⑤ trigger signaling trigger signal The judgment is made by one or more of the five items of the time slot offset value configured by the signal resource set. In addition, it can be understood that each item ①-⑤ has multiple implementation manners in subsequent embodiments, and multiple implementation manners under each item ①-⑤ can be freely combined and used.

For example, an example of judging the transmission condition according to ① uplink and downlink pattern configuration is:

If a time slot includes at least one uplink or flexible symbol configured by higher layer signaling, the time slot is a time slot that satisfies transmission conditions.

For another example, an example of judging the transmission condition according to ① uplink and downlink pattern configuration and ② trigger signaling and signal transmission time interval is:

If a time slot includes at least one uplink or flexible symbol configured by high-level signaling and is a time slot that meets the first time requirement, the time slot is a time slot that meets the transmission condition; the first time requirement is: carrying The time interval between the channel of the trigger signaling and the symbol of the first signal resource is not less than the first minimum time requirement; or, the time interval between the channel carrying the trigger signaling and the symbol of the first signal resource The time interval is greater than the first minimum time requirement.

There are more examples in the subsequent embodiments for the free combination of multiple implementation manners under each item ①-⑤, which will not be described in detail here.

In this embodiment, for the first case, the uplink and downlink pattern configuration may be the uplink and downlink pattern configuration configured by the network device for the terminal device through at least one of RRC signaling, MAC-CE signaling, or DCI signaling; The uplink and downlink pattern configuration may also be the uplink and downlink pattern configuration of the carrier or cell where the signal is located, configured by the network device for the terminal device.

Based on the content of the foregoing embodiment, in this embodiment, according to the configuration of the uplink and downlink patterns, determining whether one or more of the multiple transmission opportunities satisfies the transmission condition includes:

The non-downlink symbols included in the time slot where the transmission opportunity that meets the transmission condition is located covers all symbols of the signal resource of the signal;

or,

The non-uplink symbols included in the time slot in which the transmission opportunity satisfying the transmission condition is located covers all symbols of the signal resource of the signal.

or,

Optionally, in this embodiment, if the uplink symbols and/or flexible symbols included in a time slot cover all symbols of the signal resources of the signal, the transmission opportunity in the time slot is the transmission opportunity that satisfies the transmission conditions; Or, if the downlink symbols and/or flexible symbols included in a time slot cover all symbols of the signal resources of the signal, the transmission opportunity in the time slot is the transmission opportunity that satisfies the transmission conditions,

In this embodiment, it can be understood that when it is determined whether one or more of the multiple transmission opportunities meet the transmission condition according to the configuration of the uplink and downlink patterns, there are two cases of the uplink and the downlink, respectively:

A. When the signal is an uplink signal, the uplink symbol and/or flexible symbol included in the time slot where the transmission opportunity that meets the transmission condition is located covers all symbols of the signal resource of the signal; optionally, when the signal is an uplink signal, The uplink symbols and/or flexible symbols included in the time slot in which the transmission opportunity that meets the transmission condition is located covers all the symbols in which the signal resource configuring the signal is configured.

B. When the signal is a downlink signal, the downlink symbols and/or flexible symbols included in the time slot where the transmission opportunity that meets the transmission condition is located covers all symbols of the signal resources of the signal. Optionally, when the signal is a downlink signal, the downlink symbols and/or flexible symbols included in the time slot where the transmission opportunity that meets the transmission condition is located covers all the symbols configured in the signal resource configuring the signal.

Based on the content of the foregoing embodiment, in this embodiment, it also includes:

Optionally, if the uplink symbols and/or flexible symbols included in a time slot cover all symbols of all signal resources included in the signal resource set through which the trigger signaling triggers the signal, the The transmission timing is a transmission timing that satisfies the transmission condition.

In this embodiment, the uplink symbols and/or flexible symbols included in the time slot where the transmission opportunity that meets the transmission condition is located covers all symbols of the signal resource of the signal, and optionally, the time slot where the transmission opportunity that meets the transmission condition is located is located The included uplink symbols and/or flexible symbols cover all symbols of all signal resources (SRS resources) included in a signal resource set (SRS resource set) through which the trigger signaling triggers the signal (eg, aperiodic SRS) .

The downlink symbols and/or flexible symbols included in the time slot where the transmission opportunity that meets the transmission condition is located covers all symbols of all the signal resources included in the signal resource set through which the trigger signaling triggers the signal. Optionally, if the downlink symbols and/or flexible symbols included in a time slot cover all symbols of all signal resources included in the signal resource set through which the trigger signaling triggers the signal, the The transmission timing is a transmission timing that satisfies the transmission condition. Similar in principle to the foregoing embodiment, the difference is that the foregoing embodiment is directed to an uplink signal, and this embodiment is directed to a downlink signal.

It can be understood that the above-mentioned one transmission opportunity can be understood as corresponding to one transmission time slot; correspondingly, according to the trigger signaling, determining the transmission position of the signal from the transmission opportunity of the signal can be understood as: according to the The trigger signaling determines the transmission position of the signal from a plurality of transmission time slots of the signal. For the above several embodiments, according to the configuration of the uplink and downlink patterns, determining whether one or more of the multiple transmission opportunities meet the transmission conditions may be implemented in at least the following manners:

If a timeslot includes at least one uplink or flexible symbol configured by high-layer signaling, the timeslot is a timeslot that satisfies the first condition; optionally, the high-layer signaling is RRC signaling; The above-mentioned higher layer signaling is MAC-CE signaling;

If the uplink and/or flexible symbols included in a time slot cover all time domain symbols of the signal resource of the signal, this time slot is a time slot that satisfies the transmission condition; for example, it is assumed that the signal resource of the signal is The configured time domain symbols are the last two symbols in the time slot, and the last two symbols included in a time slot are both uplink symbols, then this time slot is a time slot that satisfies the first condition; The time domain symbols in which the signal resources are configured are the last two symbols in the time slot, and one of the last two symbols included in a time slot is an uplink symbol and the other is a flexible symbol, then this time slot is a time slot that satisfies the first condition ; For another example, the time domain symbols in which the signal resources of the signal are configured are the last 2 symbols in the time slot, and the last two symbols included in a time slot include a downlink symbol, then this time slot is not one that satisfies the first conditional time slot;

If the uplink and/or flexible symbols included in a time slot cover the time domain symbols of all signal resources in the signal resource set through which the trigger signaling triggers the signal, the time slot is a time slot that satisfies the transmission conditions For example, suppose that the trigger signaling triggers the signal through signal resource set 1, and this signal resource set includes the signal resource of the signal (may be marked as signal resource 1) and another signal resource (maybe Denoted as signal resource 2), it is assumed that the time domain symbols configured for signal resource 1 are the last two symbols in the time slot, and the time domain symbols configured for signal resource 2 are the last three symbols in the time slot. If the last 3 symbols included in a time slot are all uplink symbols, this time slot is a time slot that satisfies the first condition; but if the last three symbols included in a time slot are downlink symbols, the last two symbols are Uplink symbol, this time slot is not a time slot that satisfies the first condition;

If the uplink and/or flexible symbols included in a time slot cover the time domain symbols in which all signal resources in all signal resource sets triggered by the trigger signaling are configured, then this time slot is a time slot that satisfies the transmission condition; For example, assuming that the trigger signaling triggers the signal resource set 1 and the signal resource set 2, and the signal resources they include are configured with time domain symbols of the 1st and 2nd symbols and the 4th and 5th symbols respectively, then Only when the 1st, 2nd, 4th, and 5th symbols of a time slot are all uplink symbols, this time slot is a time slot that satisfies the first condition, otherwise this time slot is not a time slot that satisfies the first condition.

In this embodiment, the trigger signaling may be downlink control information DCI signaling.

Based on the content of the foregoing embodiment, in this embodiment, according to the priority of the signal, determining whether one or more of the multiple transmission opportunities satisfies the transmission condition includes at least one of the following:

The priority of the signal in the time slot where the transmission opportunity that meets the transmission condition is at least partially overlapped with the time domain symbol of the signal is equal to or lower than that of the signal (that is, the signal in the time slot where the transmission opportunity that meets the transmission condition is located). The priority of the signal is equal to or lower than the time-domain symbol overlap of the signal and the signal); the overlap includes partial overlap and/or total overlap. For example, a transmission opportunity corresponding to the signal occupies the 10th and 11th symbols in a time slot, and the base station schedules a signal with a higher priority than the signal in the 10th symbol of this time slot , then there is a signal with a higher priority than the signal in the time slot where this transmission opportunity is located and the time domain symbol of the signal overlaps, and this transmission opportunity is not an opportunity to meet the transmission conditions;

In the time slot where the transmission opportunity that satisfies the transmission condition is located, the signal whose time domain symbol at least partially overlaps with the signal time domain symbol corresponding to the first signal resource set has a priority equal to or lower than that of the signal corresponding to the first signal resource set (that is, the signal that satisfies the transmission condition). In the time slot where the transmission opportunity is located, there is no signal with a higher priority than the signal corresponding to the first signal resource set and the time domain symbol of the signal corresponding to the first signal resource set overlaps); In the time slot where the transmission opportunity is located, there is no signal with a higher priority than the signal corresponding to any signal resource set triggered by the trigger signaling and the time domain symbol of the signal corresponding to the signal resource set overlaps, that is, the transmission condition is satisfied. In the time slot where the transmission opportunity is located, there is no signal with a higher priority than the signal triggered by the trigger signaling on the time domain symbols of the signal resources included in all the signal resource sets triggered by the trigger signaling; The first signal resource set is the signal resource set used when the trigger signaling triggers the signal; optionally, for the kth transmission opportunity of the signal resource set corresponding to a signal, if the The time slot is the mth transmission opportunity of another signal resource set (m<k), then the priority of the other signal resource set is higher than that of the signal resource set of the signal; optionally, whether the transmission opportunity of a signal is The transmission opportunity that satisfies the transmission condition is determined according to the transmission opportunity corresponding to the signal resource set corresponding to this signal. In this case, whether the transmission opportunity of the signal is a transmission opportunity that satisfies the transmission condition is determined according to the transmission opportunity corresponding to the first signal resource set. Optionally, if the time slot where the transmission opportunity corresponding to a signal resource set is located has a signal with a higher priority than the signal corresponding to the signal resource set and the signal time domain symbol corresponding to the signal resource set overlaps, then the signal resource set corresponds to This transmission opportunity is not a transmission opportunity for which the signal resources in the signal resource set (signals corresponding to the signal resources) satisfy the transmission conditions. For example, one transmission opportunity corresponding to one SRS resource set is on one time slot, all SRS resources included in this SRS resource set are on the 10th and/or 11th symbol, and the base station is on the 10th symbol of this time slot. A signal with a higher priority than the signal corresponding to the SRS resource set is scheduled for each symbol, then there is a signal with a higher priority than the signal corresponding to the SRS resource set and a signal corresponding to the SRS resource set on the time slot where the transmission opportunity is located. The time domain symbols overlap, and this transmission opportunity is not an opportunity to meet the transmission conditions;

The priority of the signal in the time slot where the transmission opportunity that meets the transmission condition is located is equal to or lower than that of the signal (that is, the priority of the signal in the time slot where the transmission opportunity that meets the transmission condition is located is equal to or lower than the signal) ; For example, a transmission opportunity corresponding to the signal occupies the 10th and 11th symbols in a time slot, and the base station schedules a higher priority than the signal in the 9th symbol of this time slot. Signal, although the symbol does not overlap, but there is a signal with a higher priority than the signal in the time slot where this transmission opportunity is located, and this transmission opportunity is not an opportunity to meet the transmission conditions;

The time slot where the transmission opportunity that satisfies the transmission condition is located is a time slot other than another signal resource set or signal resource triggered by the trigger signaling; for example, when judging whether a transmission opportunity of an SRS satisfies the transmission condition When transmitting an opportunity, if the time slot in which this transmission opportunity is located has been determined to transmit another SRS resource set triggered by the trigger signaling, this transmission opportunity is not a transmission opportunity that satisfies the transmission condition. Optionally, a transmission opportunity in a time slot that has been determined to transmit another SRS resource set triggered by the trigger signaling is directly determined as not a transmission opportunity that satisfies the transmission condition; or,

In this embodiment, the priority of a signal that at least partially overlaps with the time domain symbol of the signal in the time slot where the transmission opportunity that meets the transmission condition is located is equal to or lower than the signal includes: partial overlap or total overlap.

In this embodiment, various implementations are provided for determining whether one or more of the multiple transmission opportunities meet the transmission conditions according to the priority of the signal. In actual use, one of the multiple transmission opportunities may be selected. It can also be used in various combinations, and can also be used in accordance with ① uplink and downlink pattern configuration ② time interval between trigger signaling and signal transmission ③ time window requirements for trigger signaling transmission and signal transmission ⑤ trigger signaling trigger signal The set of passed signal resources is used in combination with one or more of the four items of the configured time slot offset value.

For example, an example of combined use according to the priority of the signal and ① uplink and downlink pattern configuration can be:

If a time slot includes at least one uplink or flexible symbol configured by high-level signaling and there is no signal with a higher priority than the signal in the time slot, the time slot is a time slot that satisfies the transmission conditions;

For example, according to the priority of the signal and ② the time interval between trigger signaling and signal transmission, the combination of use can be as follows:

If a time slot is a time slot that meets the first time requirement and there is no signal with a higher priority than the signal on the time slot, the time slot is a time slot that meets the transmission condition; the first time requirement is: the time interval between the channel carrying the trigger signaling and the symbol of the first signal resource is not less than the first minimum time requirement.

Based on the content of the foregoing embodiment, in this embodiment, according to the time interval between the trigger signaling and the signal transmission, it is determined whether one or more of the multiple transmission opportunities satisfy the transmission condition, including: satisfying the transmission condition The time slot where the conditional transmission opportunity is located satisfies the first time interval condition; the first time interval condition includes: the time interval between the trigger signaling and the signal transmission satisfies the first minimum time requirement, wherein the trigger signaling Let the time interval with the signal transmission be the time interval between the channel carrying the trigger signaling and the symbol of the signal resource of the signal in the time slot. For example, the trigger signaling is DCI, and the signal is SRS. For a certain time slot, the time interval between the trigger signaling and the transmission of the SRS signal is: the last symbol of the PDCCH carrying the DCI triggering the SRS resource and the time slot The time interval between the first symbols of the SRS resources of this SRS signal.

Optionally, it is judged whether the time slot in which a transmission opportunity is located satisfies the first time interval condition, and if the first time interval condition is not met, it is not a transmission opportunity that satisfies the transmission condition. Optionally, if a time slot in which a transmission opportunity is located satisfies the first time interval condition, it is a transmission opportunity that satisfies the transmission condition. Optionally, if there are other conditions (such as priority requirements, etc.), if the time slot in which a transmission opportunity is located satisfies the first time interval condition and at the same time satisfies other conditions, then this transmission opportunity is a transmission opportunity that satisfies the transmission conditions.

When the base station triggers the SRS resource set through DCI when triggering the aperiodic SRS transmission, the UE will transmit the SRS corresponding to the SRS resource in the triggered SRS resource set.

An example of the algorithm in this embodiment is: the UE determines the first transmission time slot (the first transmission opportunity) of the SRS resource set triggered by the DCI, and judges for each SRS resource set whether the SRS resource set can be used in its corresponding SRS resource set. The first transmission time slot (the first transmission opportunity) is transmitted (that is, for each SRS resource set, it is judged whether the first transmission opportunity of the SRS resource set is the first transmission opportunity, and the first transmission opportunity means that the transmission conditions are met. transmission opportunities);

For the SRS resource set that can be transmitted in its corresponding first transmission time slot (the first transmission opportunity is the first transmission opportunity), the UE transmits its corresponding SRS in its corresponding first transmission time slot;

For the SRS resource set that cannot be transmitted in its corresponding first transmission time slot (the first transmission opportunity is not the first transmission opportunity), the UE determines its corresponding second transmission time slot (the second transmission opportunity), if it is in its corresponding second transmission time slot (the second transmission opportunity) The corresponding second transmission time slot can transmit (the second transmission opportunity is the first transmission opportunity), then the UE transmits its corresponding SRS in the second transmission time slot; otherwise (the second transmission opportunity is not the first transmission opportunity) ), the UE does not transmit its corresponding SRS.

In the above embodiments, optionally, it may be determined whether a transmission opportunity in a time slot is a transmission opportunity that meets the transmission condition according to the conditions that the time slot in which the transmission opportunity that satisfies the transmission condition should be located.

The above algorithm can be generalized to a scenario where the SRS transmission corresponding to the SRS resource set has more transmission opportunities. The method provided by this embodiment is described in detail below through a specific processing process:

Step 1: The UE determines the first transmission time slot (the first transmission opportunity) of the SRS resource set triggered by the DCI, and judges whether the SRS resource set can be performed in the corresponding first transmission time slot for each SRS resource set. Transmission (that is, for each SRS resource set, determine whether the first transmission opportunity of the SRS resource set is the first transmission opportunity); set k=1;

Step 2: For the SRS resource set that can be transmitted in its corresponding kth transmission time slot (that is, the kth transmission opportunity is the first transmission opportunity), the UE performs its corresponding SRS in its corresponding kth transmission time slot. transmission; otherwise (that is, the k-th transmission opportunity is not the first transmission opportunity), set k=k+1, if the termination condition is satisfied, the UE will no longer transmit the SRS corresponding to the untransmitted SRS resource set, if the termination condition is not satisfied condition, go to step 2.

Optionally, if a time slot has been determined to be used to transmit a certain SRS resource set, the time slot is no longer the first transmission opportunity for other SRS resource sets.

Optionally, if a time slot has been determined to transmit a certain SRS resource set, the time slot is no longer the first transmission opportunity for other SRS resource sets with different time slot offset values configured by RRC signaling. .

Optionally, if at least part of the symbols in which all SRS resources in an SRS resource set in a time slot are configured are configured or scheduled with a signal with a higher priority than the aperiodic SRS, the time slot is not the aperiodic SRS. The first transmission opportunity of the SRS resource set. For example, if the UE does not support the simultaneous transmission of SRS and PUCCH/PUSCH when intra-band carrier aggregation (intra-band carrier aggregation) or in inter-band CA band combination (inter-band carrier aggregation), if a certain carrier is in a time slot When PUSCH/UL DM-RS/UL PT-RS/PUCCH is configured on a certain symbol of , this time slot is not the first transmission opportunity of the aperiodic SRS resource set configured with this symbol on another carrier.

Optionally, if at least part of the symbols in which all SRS resources in an SRS resource set are configured are downlink time slots in a time slot, the time slot is not the first transmission opportunity that can be used in the SRS resource set.

Optionally, if all symbols on which all SRS resources in an SRS resource set are configured are uplink symbols and/or flexible symbols in a time slot, the time slot is the first transmission opportunity for the SRS resource set.

Optionally, if all the symbols in which all SRS resources in one SRS resource set are configured are uplink symbols and/or flexible symbols in one time slot, and the time slot is not determined to be used to transmit other SRS resource sets, then The time slot is the first transmission opportunity of the SRS resource set.

Optionally, if all the symbols in which all SRS resources in one SRS resource set are configured are uplink symbols and/or flexible symbols in one time slot, and the time slot is not determined to be used to transmit RRC signals Let the configured time slot offset value be different from other SRS resource sets, then this time slot is the first transmission opportunity of this SRS resource set.

The manner of determining the first transmission time slot (the first transmission opportunity) and the kth transmission time slot (the kth transmission opportunity) will be explained below.

First transmission slot (first transmission opportunity)

Optionally, the first transmission time slot (the first transmission opportunity) of an SRS resource set is: a transmission time slot determined by the UE according to the time slot offset signaling configured by the network device for the SRS resource set. Optionally, the time slot offset signaling may be one or more signalings. For example, the time slot offset indicated by RRC signaling and the time slot offset indicated by DCI are included.

For example, the network device configures a time slot offset value for an SRS resource set, and the time slot offset value is used to indicate that the transmission time slot of the SRS resource in the SRS resource set is relative to the time when the DCI triggering the SRS resource set is located Offset value of the slot. The transmission time slot determined by the UE according to the time slot where the DCI that triggers the SRS resource set is located and the time slot offset value is the first transmission time slot (the first transmission opportunity).

Optionally, the first transmission time slot (the first transmission opportunity) of an SRS resource set is a default transmission time slot of the SRS resource set.

The kth transmission slot (k>1) (the kth transmission opportunity)

Optionally, the kth transmission time slot (the kth transmission opportunity) of an SRS resource set is: the first time slot offset signaling and the second time slot offset value configured by the UE for the SRS resource set according to the network device are common. Determined transmission time slot. The second time slot offset value may be the time slot offset value indicated by the network device (through RRC signaling/MAC-CE signaling/DCI signaling, etc.), or may be a value agreed in a protocol, or may be a terminal A value determined according to certain rules.

Optionally, the kth transmission time slot (the kth transmission opportunity) is the second time delay k-1 times from the time slot determined by the UE according to the first time slot offset signaling configured by the network device for the SRS resource set. The slot corresponding to the slot offset value.

Optionally, the kth transmission time slot (the kth transmission opportunity) is the second time delay k-1 times from the time slot determined by the UE according to the first time slot offset signaling configured by the network device for the SRS resource set. The slot offset value is a time slot corresponding to the time slot satisfying the first condition. The time slot that satisfies the first condition may be based on at least one of uplink and downlink pattern configuration, minimum time interval requirement for SRS and DCI transmission, time window requirement for SRS transmission and DCI transmission, and priority of signal transmission item determined. Some definitions include (assuming that the SRS is configured over a first SRS resource and triggered over a first set of SRS resources).

As shown in Figure 3, a flow chart of steps of a signal transmission method applied to a network device side provided by an embodiment of the present application, the method includes the following steps:

Step 301: Determine the transmission position of the signal from the transmission opportunity of the signal;

Step 302: Send trigger signaling for triggering the transmission or reception of the signal, where the trigger signaling is associated with the transmission position of the signal and/or the transmission opportunity.

Optionally, after the transmission position of the signal is determined, the signal is received according to the transmission position. Optionally, the receiving the signal according to the transmission location includes: receiving the signal at the transmission location. Optionally, the receiving the signal according to the transmission position includes: receiving the signal on a partial symbol of the transmission position.

In this embodiment, it can be understood that the network device will send trigger signaling for triggering the transmission or reception of the signal, and the trigger signaling is related to the transmission position and/or the transmission opportunity of the signal. connection relation.

In the signal transmission method provided by the embodiment of the present application, the transmission position of the signal is determined from multiple transmission opportunities of the signal, and according to the transmission position of the signal, a trigger signaling for triggering the transmission or reception of the signal is sent, It can be seen that the embodiments of the present application increase the opportunity for signal transmission, and increase the flexibility of signal resource scheduling and transmission.

Based on the content of the foregoing embodiment, in this embodiment, determining the transmission position of the signal from the transmission opportunity of the signal includes:

Based on the content of the foregoing embodiment, in this embodiment, determining the transmission position of the signal from multiple transmission opportunities of the signal includes:

In this embodiment, according to the trigger signaling, one or more of the multiple transmission opportunities are sequentially judged whether the transmission conditions are met, until N transmission opportunities satisfying the transmission conditions are determined or until the Termination condition, N is an integer greater than or equal to 1. It should be noted that the order here is not necessarily to judge all the transmission opportunities, but to judge some or all of the transmission opportunities.

Based on the content of the above embodiment, in this embodiment, it is determined whether one or more of the multiple transmission opportunities satisfy the transmission condition, until N transmission opportunities that satisfy the transmission condition are determined or until the Termination conditions, including:

Among them, the initial value of k is 1.

In this embodiment, it is given to judge whether one or more of the multiple transmission opportunities meet the transmission condition according to the trigger signaling, until N transmission opportunities that meet the transmission condition are determined or The specific implementation process until the termination condition is reached, according to the above description, this embodiment judges whether each transmission opportunity satisfies the transmission condition in turn, if so, continues to judge whether N transmission opportunities are determined, if so, stop, otherwise continue to judge Until N transmission opportunities are determined. In addition, when the termination condition is satisfied, the judgment of whether or not the transmission condition is satisfied will no longer be made.

Up and down pattern configuration;

the time interval between the trigger signaling and the signal transmission;

the priority of the signal; or,

or,

In this embodiment, it can be understood that when it is determined whether one or more of the multiple transmission opportunities meet the transmission conditions according to the configuration of the uplink and downlink patterns, there are two cases of the uplink and the downlink, respectively: A is in the signal When it is an uplink signal, the uplink symbol and/or flexible symbol included in the time slot where the transmission opportunity that meets the transmission condition is located covers all symbols of the signal resource of the signal; optionally, when the signal is an uplink signal, The uplink symbols and/or flexible symbols included in the time slot where the transmission opportunity is located covers all the symbols configured with the signal resource configuring the signal.

The downlink symbols and/or flexible symbols included in the time slot where the transmission opportunity satisfying the transmission condition is located covers all symbols of all the signal resources included in the signal resource set through which the trigger signaling triggers the signal.

Similar in principle to the foregoing embodiment, the difference is that the foregoing embodiment is directed to an uplink signal, and this embodiment is directed to a downlink signal.

If a timeslot includes at least one uplink or flexible symbol configured by high-layer signaling, the timeslot is a timeslot that satisfies the first condition; optionally, the high-layer signaling is RRC signaling; The higher layer signaling is MAC-CE signaling. If the uplink and/or flexible symbols included in a time slot include all time domain symbols of the signal resource of the signal, then this time slot is a time slot that satisfies the transmission condition; for example, it is assumed that the signal resource of the signal is The configured time domain symbols are the last two symbols in the time slot, and the last two symbols included in a time slot are both uplink symbols, then this time slot is a time slot that satisfies the first condition; The time domain symbols in which the signal resources are configured are the last two symbols in the time slot, and one of the last two symbols included in a time slot is an uplink symbol and the other is a flexible symbol, then this time slot is a time slot that satisfies the first condition ; For another example, the time domain symbols in which the signal resources of the signal are configured are the last 2 symbols in the time slot, and the last two symbols included in a time slot include a downlink symbol, then this time slot is not one that satisfies the first conditional time slot;

If the uplink and/or flexible symbols included in a time slot include time domain symbols of all signal resources in the signal resource set through which the trigger signaling triggers the signal, the time slot is a time slot that satisfies the transmission conditions For example, suppose that the trigger signaling triggers the signal through signal resource set 1, and this signal resource set includes the signal resource of the signal (may be marked as signal resource 1) and another signal resource (maybe Denoted as signal resource 2), it is assumed that the time domain symbols configured for signal resource 1 are the last two symbols in the time slot, and the time domain symbols configured for signal resource 2 are the last three symbols in the time slot. If the last 3 symbols included in a time slot are all uplink symbols, this time slot is a time slot that satisfies the first condition; but if the last three symbols included in a time slot are downlink symbols, the last two symbols are Uplink symbol, this time slot is not a time slot that satisfies the first condition;

If the uplink and/or flexible symbols included in a time slot include time domain symbols in which all signal resources in all signal resource sets triggered by the trigger signaling are configured, then this time slot is a time slot that satisfies the transmission condition; For example, assuming that the trigger signaling triggers the signal resource set 1 and the signal resource set 2, and the signal resources they include are configured with time domain symbols of the 1st and 2nd symbols and the 4th and 5th symbols respectively, then Only when the 1st, 2nd, 4th, and 5th symbols of a time slot are all uplink symbols, this time slot is a time slot that satisfies the first condition, otherwise this time slot is not a time slot that satisfies the first condition.

The priority of a signal that at least partially overlaps the time domain symbol of the signal in the time slot in which the transmission opportunity satisfying the transmission condition is located is equal to or lower than that of the signal; for example, one transmission opportunity corresponding to the signal is in a time domain. The 10th and 11th symbols are occupied on the slot, and the base station schedules a signal with a higher priority than the signal in the 10th symbol of this time slot, then the time slot where this transmission opportunity is located has a higher priority than the signal. The signal with the high signal overlaps with the time domain symbol of the signal, and this transmission opportunity is not an opportunity to meet the transmission conditions;

The priority of the signal whose time-domain symbols at least partially overlap with the signal time-domain symbols corresponding to the first signal resource set in the time slot where the transmission opportunity that meets the transmission condition is located is equal to or lower than that of the signal corresponding to the first signal resource set; optionally, further Therefore, there is no signal with a higher priority than the signal corresponding to any signal resource set triggered by the trigger signaling in the time slot where the transmission opportunity that meets the transmission conditions is located and the signal time domain symbol corresponding to the signal resource set overlaps. That is to say, in the time slot where the transmission opportunity that satisfies the transmission condition is located, there is no signal resource whose priority is higher than that of the signal triggered by the trigger signaling on the time domain symbols of the signal resources included in all the signal resource sets triggered by the trigger signaling. wherein the first signal resource set is the signal resource set used when the trigger signaling triggers the signal; optionally, for the kth transmission opportunity of the signal resource set corresponding to a signal That is, if the time slot in which it is located is the mth transmission opportunity of another signal resource set (m<k), the priority of the other signal resource set is higher than that of the signal resource set of the signal; optionally, a Whether the transmission opportunity of the signal is a transmission opportunity that satisfies the transmission condition is determined according to the transmission opportunity corresponding to the signal resource set corresponding to the signal. In this case, whether the transmission opportunity of the signal is a transmission opportunity that satisfies the transmission condition is determined according to the transmission opportunity corresponding to the first signal resource set. Optionally, if the time slot where the transmission opportunity corresponding to a signal resource set is located has a signal with a higher priority than the signal corresponding to the signal resource set and the signal time domain symbol corresponding to the signal resource set overlaps, then the signal resource set corresponds to This transmission opportunity is not a transmission opportunity for which the signal resources in the signal resource set (signals corresponding to the signal resources) satisfy the transmission conditions. For example, one transmission opportunity corresponding to one SRS resource set is on one time slot, all SRS resources included in this SRS resource set are on the 10th and/or 11th symbol, and the base station is on the 10th symbol of this time slot. A signal with a higher priority than the signal corresponding to the SRS resource set is scheduled for each symbol, then there is a signal with a higher priority than the signal corresponding to the SRS resource set and a signal corresponding to the SRS resource set on the time slot where the transmission opportunity is located. The time domain symbols overlap, and this transmission opportunity is not an opportunity to meet the transmission conditions;

The priority of the signal in the time slot where the transmission opportunity that satisfies the transmission condition is located is equal to or lower than that of the signal; for example, a transmission opportunity corresponding to the signal occupies the 10th and 11th time slots in one time slot symbol, the base station schedules a signal with a higher priority than the signal in the 9th symbol of this time slot. Although the symbols do not overlap, there is a signal with a higher priority than the signal in the time slot where this transmission opportunity is located. , this transmission opportunity is not an opportunity to meet the transmission conditions;

The time slot in which the transmission opportunity that satisfies the transmission condition is located is a time slot other than another signal resource set or signal resource triggered by the trigger signaling (that is, the time slot in which the transmission opportunity that satisfies the transmission condition is located is not determined. used to transmit other signal resource sets or signal resources triggered by the trigger signaling); for example, when judging whether an SRS transmission opportunity is a transmission opportunity that satisfies the transmission conditions, if the time slot where this transmission opportunity is located has been determined to be used to transmit another SRS resource set triggered by the trigger signaling, this transmission opportunity is not a transmission opportunity that satisfies the transmission condition. Optionally, a transmission opportunity in a time slot that has been determined to transmit another SRS resource set triggered by the trigger signaling is directly determined as not a transmission opportunity that satisfies the transmission condition; or,

The time domain symbol corresponding to the signal in the time slot where the transmission opportunity that satisfies the transmission condition is located is a time domain symbol other than the other signal resource set or signal resource triggered by the transmission of the trigger signaling (that is, the time domain symbol that satisfies the transmission condition). The time domain symbol corresponding to the signal in the time slot where the transmission opportunity is located is not determined to transmit other signal resource sets or signal resources triggered by the trigger signaling).

The time slot where the transmission opportunity that meets the transmission condition is located satisfies the first time interval condition; the first time interval condition includes: the time interval between the trigger signaling and the signal transmission meets the first minimum time requirement, wherein the The time interval between the trigger signaling and the signal transmission is the time interval between the channel carrying the trigger signaling and the symbol of the signal resource of the signal on the time slot. For example, the trigger signaling is DCI, and the signal is SRS. For a certain time slot, the time interval between the trigger signaling and the transmission of the SRS signal is: the last symbol of the PDCCH carrying the DCI that triggers the SRS resource and the time slot The time interval between the first symbols of the SRS resources of the SRS signal in .

For example, DCI triggers _N _SRS resources, respectively _denoted as _S ₁ , . Less than k _m , m∈{1,...,N}. Then the first minimum time requirement corresponding to the SRS resource S _m is not less than _km , m∈{1,...,N};

Optionally, the first time interval corresponding to an SRS resource set is pre-agreed by the base station and the terminal;

The time slot where the transmission opportunity that satisfies the transmission condition is located satisfies the second time interval condition; the second time interval condition includes: the channel carrying the trigger signaling and the time interval of symbols of all signal resources in the first signal resource set All meet the first minimum time requirement;

For example, the trigger signaling is DCI, and the signal is SRS. Optionally, if a timeslot is a timeslot that satisfies the following conditions, the timeslot is a timeslot that satisfies the transmission conditions: The time interval between the last symbol and the first symbol in the symbols of all SRS resource sets/SRS resources triggered by the DCI satisfies the first minimum time requirement.

In this embodiment, the time slot in which the transmission opportunity satisfying the transmission condition is located needs to satisfy the first minimum time requirement for the channel carrying the trigger signaling and the time interval of the symbols of all signal resources in the first signal resource set.

For example, the trigger signaling is DCI, and the signal is SRS. Optionally, the time interval between the last symbol of the PDCCH carrying the DCI and the first symbol among the symbols of all SRS resources triggered by the DCI satisfies the first minimum time requirement.

For example, trigger signaling triggers N signal resource sets, which are respectively represented as S ₁ ,...,S _N , and their corresponding minimum time requirements are respectively: not less than k ₁ ,...,k _N , that is, the corresponding signal resource sets S _m The minimum time requirement is not less than k _m , m∈{1,...,N}. Then, the first minimum time requirement corresponding to the signal triggered by being configured in the signal resource set S _m is not less than _km , m∈{1,...,N}.

For example, the trigger signaling triggers N signal resources, which are respectively denoted as S ₁ ,...,S _N , and their corresponding first time intervals are respectively: k ₁ ,...,k _N , that is, the minimum time interval corresponding to S _m is k _m , m∈{1,…,N}. Then the first minimum time requirement is: not less than max{k ₁ ,...,k _N }, that is, not less than the maximum value among k ₁ ,...,k _N.

Optionally, the first minimum time requirement is not less than the maximum value in the first time interval corresponding to all signal resource sets triggered by the trigger signaling.

Optionally, the first time interval corresponding to one signal resource set type is pre-agreed by the network device and the UE.

Based on the content of the foregoing embodiment, in this embodiment, it is determined whether one or more of the multiple transmission opportunities meet the transmission condition according to the transmission of the trigger signaling and the time window requirements of the transmission of the signal, Include at least one of the following:

For example, the trigger signaling is DCI, and the signal is SRS. Optionally, if all the symbols in which all SRS resources in one SRS resource set are configured are uplink symbols or flexible symbols in one time slot, and the time slot does not have For other SRS resource sets that are determined to be used to transmit the time slot offset value configured by the RRC signaling, the time slot is a transmission opportunity of the SRS resource set that satisfies the transmission conditions.

For example, the trigger signaling is DCI, and the signal is SRS. Optionally, the first transmission time slot of an SRS resource set is: UE determined according to the time slot offset signaling configured by the network device for the SRS resource set transmission time slot. Optionally, the time slot offset signaling may be one or more signalings. For example, the time slot offset indicated by RRC signaling and the time slot offset indicated by DCI are included. For example, the network device configures a time slot offset value for an SRS resource set, and the time slot offset value is used to indicate that the transmission time slot of the SRS resource in the SRS resource set is relative to the time when the DCI triggering the SRS resource set is located Offset value of the slot. The transmission time slot determined by the UE according to the time slot where the DCI that triggers the SRS resource set is located and the time slot offset value is the first transmission time slot (the first transmission opportunity). Optionally, the first transmission time slot (the first transmission opportunity) of an SRS resource set is a default transmission time slot of the SRS resource set.

Based on the contents of the foregoing embodiments, in this embodiment, the method further includes:

For example, the trigger signaling is DCI, and the signal is SRS. Optionally, the kth transmission time slot (the kth transmission opportunity) is determined by the UE according to the first time slot offset signaling configured by the network device for the SRS resource set. The time slot corresponding to the second time slot offset value is delayed by k-1 times from the output time slot. Optionally, the kth transmission time slot (the kth transmission opportunity) is the second time delay k-1 times from the time slot determined by the UE according to the first time slot offset signaling configured by the network device for the SRS resource set. The slot offset value is a time slot corresponding to the time slot satisfying the first condition. The time slot that satisfies the first condition may be based on at least one of uplink and downlink pattern configuration, minimum time interval requirement for SRS and DCI transmission, time window requirement for SRS transmission and DCI transmission, and priority of signal transmission item determined.

Based on the content of the foregoing embodiment, in this embodiment, determining the transmission opportunity according to the time slot offset signaling indicated by the signal resource set used for triggering the signal for the trigger signaling includes:

The transmission opportunity is determined according to the time slot jointly determined by the first time slot offset signaling configured for the signal resource set through which the signal is triggered by the trigger signaling and the first time slot offset value; A time slot offset value is a time slot offset value indicated to the terminal device or a value agreed in advance through a protocol or a value determined according to a preset rule.

For example, the trigger signaling is DCI, and the signal is SRS. Optionally, the network device configures a slot offset value for an SRS resource set, and the slot offset value is used to indicate the SRS in the SRS resource set. The offset value of the transmission time slot of the resource relative to the time slot where the DCI that triggers the SRS resource set is located. The transmission time slot determined by the UE according to the time slot where the DCI that triggers the SRS resource set is located and the time slot offset value is the first transmission time slot (the first transmission opportunity). The network device may indicate the time slot offset value through RRC signaling, MAC-CE signaling or DCI. Optionally, the first time slot offset value is indicated by the DCI carrying the trigger signaling.

Adjacent transmission opportunities in the plurality of transmission opportunities are separated by a second time slot offset value of time slots; or, adjacent transmission opportunities in the plurality of transmission opportunities are separated by a third time slot offset value of time slots satisfying the first A time slot of a condition; the time slot satisfying the first condition is based on the priority of the signal, the configuration of the uplink and downlink patterns, the time interval requirement for the transmission of the signal and the trigger signaling, and the time window for the transmission of the signal and the transmission of the trigger signaling The requirement is determined by at least one item of the first time slot offset signaling.

the fourth preset value;

A value determined according to the usage type of the signal resource set.

The value indicated by signaling;

The value agreed in the agreement;

A value related to the numerology of the BWP where the signal resource set triggered by the trigger signaling is located;

Based on the content of the foregoing embodiment, in this embodiment, one transmission opportunity corresponds to one transmission time slot; determining the transmission position of the signal from multiple transmission opportunities of the signal includes:

The transmission position of the signal is determined from the plurality of transmission time slots. It should be noted that the principle of the signal transmission method applied to the network device provided in this embodiment is similar to the above-mentioned signal transmission method applied to the terminal device. Repeat.

The present application will be specifically described below through specific examples.

This embodiment takes a maximum of two transmission opportunities for each SRS resource set as an example to introduce the embodiment, which can be extended to more transmission opportunities for each SRS resource set.

The base station sends configuration information of the SRS resource set to the UE, where the configuration information includes a slot offset value corresponding to the SRS resource set.

The base station sends the DCI signaling to the UE in time slot n to trigger the UE to transmit the aperiodic SRS resource. The DCI signaling triggers the UE to transmit SRSs corresponding to M SRS resource sets (M is an integer greater than or equal to 1). Optionally, the DCI signaling can be DCI format 0_1, DCI format 0_2, DCI format 1_1, DCI format 1_2, or DCI format 2_3, etc.

After receiving the DCI signaling, the UE determines the first transmission time slot (the first transmission opportunity) corresponding to each of the M SRS resource sets triggered by the DCI. Assuming that the SRS resource set triggered by the DCI is denoted as S _k , the first transmission slot of the SRS resource set S _k is the s _k th slot from the slot n where the DCI is located. The _sk is the time slot offset value (k∈{1, . . . , M}) configured by the configuration information of the SRS resource set _Sk .

For the SRS resource set that can be transmitted in its corresponding first transmission time slot, the UE transmits its corresponding SRS in its corresponding first transmission time slot. An example of M=4 is shown in FIG. 4 , in which D represents a downlink time slot and U represents an uplink time slot. In this example, s ₁ , s ₂ , s ₃ , and s ₄ corresponding to S ₁ , S ₂ , S ₃ , and S 4 are 2, 3, 10, and ₅ , respectively. Then the first transmission time slots corresponding to S ₁ , S ₂ , S ₃ , and S ₄ are time slots n+2, n+3, n+10, and n+5, respectively.

In this embodiment, optionally, if a time slot has been determined to be used to transmit a certain SRS resource set, the time slot is no longer the first transmission opportunity for other SRS resource sets.

Optionally, if all symbols configured in one SRS resource set are uplink symbols or flexible symbols in one time slot, the time slot is a time slot that can transmit the SRS resource set. If a time slot included in a transmission opportunity can satisfy the above conditions, the transmission opportunity is the first transmission opportunity. The first transmission opportunity in this embodiment refers to a transmission opportunity that satisfies transmission conditions.

Therefore, since time slot n+2 and time slot n+10 are both upstream time slots (all symbols are upstream symbols), they are the first transmission opportunities to transmit S ₁ and S ₃ respectively, since time slot n+ 3 and time slot n+5 are both downlink time slots (all symbols are downlink symbols), so time slot n+ ₃ is not the first transmission opportunity of S2, and time slot n+ ₅ is not the first transmission opportunity of S4 .

The UE determines that the _second time slot offsets corresponding to S2 and S4 are delayed by ₄ and 5 time slots respectively based on the first transmission time slot (in this embodiment, the UE determines it according to the information indicated by the base station). Then the UE determines that the _second transmission time slots of S2 and S4 are n+3+ ₄ =n+7 and n+5+5=n+10, respectively. Since slot n+ ₁₀ has been used to transmit S4, it is no longer the first transmission opportunity for any other set of SRS resources. The uplink time slot n+7 is the available time slot of S ₂ , that is, the first transmission opportunity of S ₂ . Then the UE transmits S ₂ in time slot n+7, and the UE does not transmit S ₄ .

It can be seen that, by means of this solution, the transmission opportunity of aperiodic SRS resources is increased, the overhead of DCI triggering SRS resources is reduced, and the flexibility of SRS resource scheduling and transmission is increased. In this solution, the SRS transmission opportunity is not a reserved resource, and can be used to transmit other signals when it is determined not to be used for SRS resource transmission.

In addition, as shown in FIG. 5 , it is a module block diagram of a signal transmission apparatus applied to a terminal device in an embodiment of the present application, and the apparatus includes:

a receiving module 11, configured to receive trigger signaling for trigger signal transmission or reception;

A determination module 12, configured to determine the transmission position of the signal from the transmission opportunity of the signal according to the trigger signaling, and/or determine the transmission opportunity of the signal according to the trigger signaling, from the transmission opportunity of the signal The transmission position of the signal is determined in the transmission opportunity of the signal.

Based on the content of the foregoing embodiment, in this embodiment, the determining module is specifically used for:

Judging whether one or more of the multiple transmission opportunities satisfy the transmission condition according to the trigger signaling, until N transmission opportunities that satisfy the transmission condition are determined or until the termination condition is reached, where N is greater than or An integer equal to 1.

Based on the content of the above-mentioned embodiment, in this embodiment, the determining module performs a judgment on whether one or more of the multiple transmission opportunities meet the transmission condition according to the trigger signaling, until N are determined. The transmission opportunity that satisfies the transmission condition or until the termination condition is reached, which specifically includes the following:

Judging whether one or more of the multiple transmission opportunities satisfy the transmission condition according to the trigger signaling, until N transmission opportunities satisfying the transmission condition are determined or until the termination condition is reached, including:

Among them, the initial value of k is 1.
