Technical Field

Background

In the existing communication system, the reference signals configured by the base station for the terminal are not always present, and the reference signals in some configurations 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 a trigger or activation signaling of the reference signal to the terminal, after receiving the signaling, the terminal needs to determine the sending time of the reference signal according to a predefined timing relationship between the trigger and the sending of the reference signal or the timing relationship signaling between the trigger and the sending of the reference signal indicated by the base station.

For example, for triggering the aperiodic Sounding Reference Signal (SRS) resource of the third generation partnership project new air interface 3gpp nr system, the triggering mode and the transmission timing rule related to the aperiodic SRS resource limit the time domain position of the Downlink Control Information (DCI) for triggering the aperiodic SRS resource, which is transmitted by the base station, and thus the triggering and transmission of the aperiodic SRS resource are not flexible enough.

Detailed Description

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, and it is obvious that the described embodiments are only a part of the embodiments of the present application, and not all of the embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present application.

As described in the background section, in the existing communication system, the reference signals configured by the base station for the terminal are not always present, and the reference signals in some configurations (for example, reference signals configured as non-periodic or semi-persistent signals) can be sent only after being triggered (trigger) or activated (activate). If the base station configures a certain reference signal for the terminal and sends a trigger or activation signaling of the reference signal to the terminal, after receiving the signaling, the terminal needs to determine the sending time of the reference signal according to a predefined timing relationship between the trigger and the sending of the reference signal or the timing relationship signaling between the trigger and the sending of the reference signal indicated by the base station.

Taking the Reference signal as an SRS for example, in a 3rd Generation Partnership Project New air interface 3GPP NR (3rd Generation Partnership Project New Radio) system, a base station configures an aperiodic SRS (or channel State Information Reference signal) Resource set and an aperiodic SRS (/ CSI-RS) Resource for a terminal device ue (user equipment) through a Radio Resource control rrc (Radio Resource control) signaling, and triggers transmission of the aperiodic SRS (/ CSI-RS) Resource through an SRS request domain (/ CSI request domain) in the DCI signaling. When configuring the aperiodic SRS (/ CSI-RS) resource set by RRC, RRC signaling slotOffset (/ aperiodicTriggeringOffset) is used to configure a trigger offset value of the SRS (/ CSI-RS) resource in the aperiodic SRS (/ CSI-RS) resource set. When a base station triggers an aperiodic SRS (/ CSI-RS) resource set through an SRS request domain (/ CSI reporting domain/CSI request domain) in DCI in a slot (slot) n, all SRS (/ CSI-RS) resources in the SRS (/ CSI-RS) resource set are in the slot

Sending, where k is a slotOffset (/ aperiodirgertriggeringOffset) pairCorresponding trigger time slot offset value, mu_SRSAnd mu_PDCCHThe subcarrier spacing values for the triggered SRS and the PDCCH carrying the trigger command, respectively.

Since the configuration of RRC signaling is semi-static, configuring the trigger offset value for aperiodic SRS through RRC signaling makes triggering of SRS inflexible. Furthermore, in TDD mode, if time slot n + n_offsetIs a downlink slot (/ uplink slot), then the slot n + n_offsetThe transmission of the SRS (/ CSI-RS) is not possible and the UE no longer transmits the SRS (/ CSI-RS). To avoid that SRS (/ CSI-RS) cannot be transmitted, this will limit the time domain location where the base station sends DCI, thereby reducing the flexibility of triggering SRS (/ CSI-RS) transmission through DCI. Fig. 1 shows all possible positions of PDCCH and SRS when the transmission of PDSCH triggering aperiodic SRS and the transmission of aperiodic SRS are completed in five time slots when the uplink and downlink time slots are configured in such a way that every five time slots are DDFUU (where D denotes downlink time slots, U denotes uplink time slots, and F denotes flexible time slots with both uplink and downlink symbols). Wherein each row represents a transmission position of one kind of PDCCH and SRS under one SRS slot offset value, and each column on the vertical represents one slot. As can be seen from fig. 1, when the trigger slot offset value is 1, the PDCCH for triggering the aperiodic SRS can only be transmitted in slot 1 or slot 2, and cannot be transmitted in any other slot, and the SRS can only be transmitted in slot 2 and slot 3. Therefore, it can be seen that, for the triggering manner of the SRS resource and the stipulation of the transmission timing sequence related to the aperiodic SRS resource, the time domain position of the downlink control information DCI triggering the aperiodic SRS resource is limited by the base station, and then the triggering and the transmission of the aperiodic SRS resource are not flexible enough, and to solve the problem, embodiments of the present invention provide a signal transmission method, an apparatus, a terminal device, a network device, and a storage medium.

The present application is explained in detail below.

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

step 101: receiving a trigger signaling for sending or receiving a trigger signal;

in this embodiment, it can be understood that the uplink signal is transmission, and the downlink signal is reception.

Step 102: and determining the transmission position of the signal from the transmission opportunity of the signal according to the trigger signaling, and/or determining the transmission opportunity of the signal according to the trigger signaling, and determining the transmission position of the signal from the transmission opportunity 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 position includes: transmitting the signal at the transmission location. Optionally, the transmitting the signal according to the transmission position includes: transmitting the signal on a portion of the symbols of the transmission location.

In this embodiment, it may be understood that a network device, such as a base station, sends a trigger signaling for transmitting or receiving a trigger signal to a terminal device UE, and after receiving the trigger signaling, the UE determines a transmission position of the signal from a transmission opportunity of the signal according to the trigger signaling. In this embodiment, the signal has n transmission opportunities (n >1) corresponding to the trigger. And the UE takes the transmission opportunity meeting 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 perform transmission or reception of the signal.

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

In this embodiment, it can be understood that the transmission opportunity (or referred to as a transmission opportunity) of the signal may be determined according to the trigger signaling in various manners, for example, the transmission opportunity may be determined according to timeslot offset signaling indicated by a set of signal resources through which the network device triggers the signal, or the transmission opportunity may be determined according to a preset timeslot offset value or a timeslot offset value determined according to a preset rule, and the like, which will be further described below. A transmission occasion of a signal may be understood as a set of alternative time-domain resources or a set of alternative time-frequency resources corresponding to the signal. One transmission opportunity may be a resource within one slot, or a resource across multiple 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 2 OFDM symbols of a slot, each transmission opportunity thereof is the last 2 OFDM symbols of a slot. For another example, assuming that an SRS resource corresponding to one SRS is configured to have one transmission opportunity of 2 OFDM symbols, there may be multiple transmission opportunities corresponding to the SRS in one slot, each transmission opportunity includes 2 OFDM symbols, and one transmission opportunity of the SRS may also span two adjacent slots. The present description will mainly describe the method and apparatus of the present invention in terms of one transmission opportunity in one time slot and one transmission opportunity in one time slot, it being understood that the method can be extended to one transmission opportunity across multiple time slots and/or multiple transmission opportunities in one time slot. In this embodiment, taking one transmission opportunity in one timeslot as an example, the transmission position of the signal may be determined from a plurality of timeslots corresponding to the signal according to the trigger signaling, and it may be determined whether one timeslot may be a timeslot where the transmission position of the signal is located through a plurality of freely combined manners, for example, in a case that one timeslot includes at least one uplink or flexible symbol configured by higher layer signaling, the timeslot is determined to be a timeslot satisfying transmission conditions, or in a case that the uplink and/or flexible symbol included in one timeslot includes all time domain symbols in which the first signal resource is configured in one timeslot, the timeslot is determined to be a timeslot satisfying transmission conditions, and the like, which will be further explained below; as can be seen from the above description, the transmission opportunity of the signal may be determined according to the trigger signaling, and then the transmission location of the signal may be determined from the transmission opportunity.

It should be noted that the present embodiment is applicable to aperiodic uplink signals (e.g., sounding Reference signal SRS), aperiodic downlink signals (e.g., CSI-rs (channel State Information Reference signal), CSI-im (channel State Information Interference measurement) Reference signals, etc.), semi-persistent uplink signals, semi-persistent downlink signals, etc. For the sake of illustrative description, the following embodiments of the present application will be described by using aperiodic SRS. Therefore, the embodiment can solve the problem that the triggering and the sending of the aperiodic signal resource are not flexible in the wireless communication system.

According to the signal transmission method provided by the embodiment of the application, the trigger signaling used for sending or receiving the trigger signal is received, and then the transmission position of the signal is determined from a plurality of transmission opportunities of the signal according to the trigger signaling.

Based on the content of the foregoing embodiment, in this embodiment, determining the transmission location of the signal from the transmission opportunities of the signal according to the trigger signaling, and/or determining the transmission opportunities of the signal from the transmission opportunities according to the trigger signaling, includes:

Determining a transmission location of the signal according to one or more of the transmission opportunities that satisfy a transmission condition;

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

One example of determining a transmission location of the signal based on one or more of the transmission opportunities that satisfy a transmission condition is:

and one or more transmission opportunities meeting the transmission condition in the transmission opportunities are taken as the transmission positions of the signals.

Another example of determining a transmission location of the signal based on one or more of the transmission opportunities that satisfy a transmission condition is:

the transmission location of the signal is determined in one or more of the transmission opportunities that meet a transmission condition, further in combination with some other information. For example, it is determined whether there are other signals having priority over the signal in the one or more transmission opportunities, and if there are other signals having priority over the signal on some symbols, these symbols are not the transmission positions of the signal, and the other symbols in the one or more transmission opportunities are the transmission positions of the signal.

Based on the content of the foregoing embodiment, in this embodiment, determining the transmission location of the signal from the transmission opportunity of the signal according to the trigger signaling includes:

And judging whether one or more of the plurality of transmission opportunities meet the transmission condition until N transmission opportunities meeting the transmission condition are determined or a termination condition is reached, wherein N is an integer greater than or equal to 1.

In this embodiment, whether one or more of the multiple transmission opportunities meet the transmission condition is sequentially determined according to the trigger signaling until N transmission opportunities meeting the transmission condition are determined or until a termination condition is reached, where N is an integer greater than or equal to 1, it should be noted that, here, the sequence is not necessarily all the transmission opportunities, and may be part or all the transmission opportunities. After determining the transmission opportunities satisfying the transmission conditions, the transmission location of the signal may be further determined according to the transmission opportunities satisfying 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 such that there is no symbol of other signal with higher priority than the signal in the transmission opportunities satisfying the transmission condition.

In this embodiment, the value of N may be set as needed, for example, optionally, N is 1; optionally, N ═ 2; optionally, N is a numerical value indicated by the base station; optionally, N is a predefined number. For example, a value agreed upon by the agreement. Optionally, N is a numerical value reported by the terminal device.

Based on the content of the foregoing embodiment, in this embodiment, determining whether one or more of the multiple transmission opportunities satisfies a transmission condition according to the trigger signaling until determining that N transmission opportunities satisfying the transmission condition or until a termination condition is reached includes:

determining whether a kth transmission opportunity of a set of signal resources through which the signal is triggered by the trigger signaling is a transmission opportunity satisfying the transmission condition; if yes, determining whether N transmission opportunities meeting the transmission condition or a termination condition is reached; if the kth transmission opportunity of the signal resource set through which the signal is triggered by the trigger signaling is not the transmission opportunity of the transmission condition or N transmission opportunities meeting the transmission condition are not determined or the termination condition is not met, taking k ═ k +1 as a circulation condition to continuously determine until N transmission opportunities meeting the transmission condition are determined or the termination condition is met; or,

determining whether a kth transmission opportunity of a signal resource of the signal is a transmission opportunity that satisfies the transmission condition; if yes, determining whether N transmission opportunities meeting the transmission condition or a termination condition is reached; if the kth transmission opportunity of the signal resource of the signal is not the transmission opportunity meeting the transmission condition or N transmission opportunities meeting the transmission condition are not determined or the termination condition is not met, taking k-k +1 as a circulation condition to continue to determine until N transmission opportunities meeting the transmission condition are determined or the termination condition is met;

Wherein the initial value of k is 1.

In this embodiment, a specific implementation process of determining 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 a termination condition is reached is given, and it can be known from the above description that this embodiment sequentially determines whether each transmission opportunity satisfies the transmission condition, if so, continues to determine whether N transmission opportunities are determined, if so, stops, otherwise, continues to determine until N transmission opportunities are determined. Further, when the termination condition is satisfied, the determination of whether the transmission condition is satisfied is not performed. After determining the transmission opportunities satisfying the transmission conditions, the transmission location of the signal may be further determined according to the transmission opportunities satisfying 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 such that there is no symbol of other signal with higher priority than the signal in the transmission opportunities satisfying the transmission condition.

Based on the content of the above embodiment, in the present embodiment, it is determined whether one or more of the plurality of transmission opportunities satisfy a transmission condition according to at least one of:

Configuring an uplink pattern and a downlink pattern;

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

the priority of the signal; or,

In this embodiment, the determination may be performed according to one or more of the five items, that is, the uplink and downlink patterns configure, the time interval between the trigger signaling and the signal transmission, the time window requirement for the transmission of the trigger signaling and the signal transmission, the priority of the signal, the time slot offset value configured for the signal resource set through which the signal trigger signal is triggered, and the like. Further, it is understood that (r) - (v) each item has various implementations in the subsequent embodiments, and (r) - (v) the various implementations under each item can be freely combined for use.

For example, an example of determining the transmission condition according to the arrangement of the (r) uplink and downlink patterns is as follows:

if a timeslot includes at least one uplink or flexible symbol configured by higher layer signaling, the timeslot is a timeslot satisfying transmission conditions.

For another example, the example of determining the transmission condition according to the uplink and downlink pattern configuration and the time interval between the triggering of the signaling and the signal transmission is as follows:

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

The following examples are further illustrative of the case where multiple implementations under each item are used in a freely combined manner, and are not described in detail here.

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

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

The non-downlink symbols included in the time slot in which the transmission opportunity meeting the transmission condition is located cover all symbols of the signal resource of the signal;

or,

and the non-uplink symbols included in the time slot in which the transmission opportunity meeting the transmission condition is positioned cover all symbols of the signal resource of the signal.

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

or,

the time slot in which the transmission opportunity satisfying the transmission condition is located includes downlink symbols and/or flexible symbols covering all symbols of the signal resources of the signal.

Optionally, in this embodiment, if the uplink symbol and/or the flexible symbol included in one timeslot covers all symbols of the signal resource of the signal, the transmission opportunity in the timeslot is a transmission opportunity that meets the transmission condition; or, if the downlink symbol and/or the flexible symbol included in a timeslot covers all symbols of the signal resource of the signal, the transmission opportunity in the timeslot is a transmission opportunity that satisfies the transmission condition,

In this embodiment, it can be understood that, when determining whether one or more of the multiple transmission opportunities satisfy a transmission condition according to the uplink and downlink pattern configuration, there are two cases, namely, uplink and downlink:

A. when the signal is an uplink signal, the uplink symbol and/or the flexible symbol included in the time slot in which the transmission opportunity meeting the transmission condition is located cover all symbols of the signal resource of the signal; optionally, when the signal is an uplink signal, the uplink symbol and/or the flexible symbol included in the time slot in which the transmission opportunity meeting the transmission condition is located cover all the symbols configured for configuring the signal resource of the signal.

B. When the signal is a downlink signal, the downlink symbol and/or the flexible symbol included in the time slot in which the transmission opportunity meeting the transmission condition is located covers all symbols of the signal resource of the signal. Optionally, when the signal is a downlink signal, the downlink symbol and/or the flexible symbol included in the time slot in which the transmission opportunity meeting the transmission condition is located cover all the symbols configured for configuring the signal resource of the signal.

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

Optionally, if the uplink symbol and/or the flexible symbol included in one timeslot covers all symbols of all signal resources included in the signal resource set through which the trigger signaling triggers the signal, the transmission opportunity in the timeslot is a transmission opportunity that satisfies the transmission condition.

In this embodiment, the uplink symbol and/or the flexible symbol included in the slot in which the transmission opportunity satisfying the transmission condition is located covers all symbols of the signal resource of the signal, and optionally, the uplink symbol and/or the flexible symbol included in the slot in which the transmission opportunity satisfying the transmission condition is located covers all symbols of all signal resources (SRS resources) included in the set of signal resources (SRS resource set) through which the trigger signaling triggers the signal (e.g., aperiodic SRS).

the downlink symbols and/or flexible symbols included in the time slot in which the transmission opportunity meeting the transmission condition is located cover all symbols of all signal resources included in the signal resource set through which the trigger signaling triggers the signal. Optionally, if the downlink symbol and/or the flexible symbol included in one timeslot covers all symbols of all signal resources included in the signal resource set through which the trigger signaling triggers the signal, the transmission time in the timeslot is a transmission time that meets the transmission condition. Similar to the principle of the above embodiments, the difference is that the above embodiments are directed to uplink signals, and the present embodiments are directed to downlink signals.

It is to be understood that the above-mentioned one transmission opportunity may be understood as corresponding to one transmission slot; accordingly, determining the transmission location of the signal from the transmission opportunity of the signal according to the trigger signaling may be understood as: determining a transmission position of the signal from a plurality of transmission time slots of the signal according to the trigger signaling. For the above embodiments, determining whether one or more of the multiple transmission opportunities satisfies the transmission condition according to the uplink and downlink pattern configuration may be implemented in at least the following manners:

if a slot includes at least one uplink or flexible symbol configured by higher layer signaling, the slot is a slot satisfying a first condition; optionally, the high layer signaling is RRC signaling; optionally, the high-level signaling is MAC-CE signaling;

a slot is a slot that satisfies the transmission condition if the uplink and/or flexible symbols included in the slot cover all time domain symbols of the signal resources of the signal; for example, assuming that the time domain symbols configured for the signal resources of the signal are the last 2 symbols in a slot, and the last two symbols included in a slot are uplink symbols, the slot is a slot satisfying the first condition; for another example, the time domain symbol configured for the signal resource of the signal is the last 2 symbols in the time slot, and one of the last two symbols included in one time slot is an uplink symbol and one is a flexible symbol, and then this time slot is a time slot that satisfies the first condition; for another example, the time domain symbol configured for the signal resource of the signal is the last 2 symbols in the time slot, and the last two symbols included in a time slot include a downlink symbol, so that the time slot is not a time slot that satisfies the first condition;

If the uplink and/or flexible symbol included in a time slot covers the time domain symbol of all signal resources in the signal resource set through which the trigger signaling triggers the signal, the time slot is a time slot meeting the transmission condition; for example, it is assumed that the trigger signaling triggers the signal through a signal resource set 1, and this signal resource set includes a signal resource (it is not labeled as signal resource 1) and another signal resource (it is not labeled as signal resource 2) of the signal, and it is assumed that the time domain symbol configured for signal resource 1 is the last 2 symbols in the slot and the time domain symbol configured for signal resource 2 is the last 3 symbols in the slot. If the last 3 symbols included in a slot are uplink symbols, the slot is a slot satisfying a first condition; however, if a slot includes the 3 rd last symbol as a downlink symbol and the last two symbols as uplink symbols, the slot is not a slot satisfying the first condition;

if the uplink and/or flexible symbol included in a time slot covers the time domain symbol configured by all signal resources in all signal resource sets triggered by the trigger signaling, the time slot is a time slot meeting the transmission condition; for example, assuming that the trigger signaling triggers signal resource set 1 and signal resource set 2, which include the time domain symbols for which the signal resources are configured to be 1 st, 2 nd symbols and 4 th, 5 th symbols, respectively, only when all the 1 st, 2 nd, 4 th, 5 th symbols of a slot are uplink symbols, the slot is a slot that satisfies the first condition, otherwise, the slot is not a 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 above embodiment, in the present embodiment, determining whether one or more of the plurality of transmission opportunities satisfies the transmission condition according to the priority of the signal includes at least one of:

a signal in a time slot in which a transmission opportunity satisfying the transmission condition is located, the signal at least partially overlapping a time domain symbol of the signal, has a priority equal to or lower than the signal (i.e., a signal in a time slot in which a transmission opportunity satisfying the transmission condition is located has a priority equal to or lower than the signal overlapping a time domain symbol of the signal); the overlap may comprise a partial overlap and/or a full overlap. For example, a transmission opportunity corresponding to the signal occupies the 10 th and 11 th symbols in a time slot, and the base station schedules a signal with higher priority than the signal in the 10 th symbol of the time slot, so that there is an overlap between the signal with higher priority than the signal and the time domain symbol of the signal in the time slot of the transmission opportunity, and the transmission opportunity is not an opportunity to satisfy the transmission condition;

the priority of the signal at least partially overlapped with the signal time domain symbol corresponding to the first signal resource set in the time slot where the transmission opportunity meeting the transmission condition is located is equal to or lower than that of the signal corresponding to the first signal resource set (that is, no signal with higher priority than the signal corresponding to the first signal resource set is overlapped with the signal time domain symbol corresponding to the first signal resource set in the time slot where the transmission opportunity meeting the transmission condition is located); optionally, further, there is no signal with higher priority than the signal corresponding to any signal resource set triggered by the trigger signaling in the time slot in which the transmission opportunity meeting the transmission condition is located, and the signal time domain symbol corresponding to the signal resource set overlaps with the signal time domain symbol corresponding to the signal resource set, that is, there is no signal with higher priority than the signal triggered by the trigger signaling in the time slot in which the transmission opportunity meeting the transmission condition is located in all the signal resource sets triggered by the trigger signaling on the time domain symbol of the signal resource; wherein the first set of signal resources is a set of signal resources through which the trigger signaling triggers the signal; optionally, for the kth transmission opportunity of a signal resource set corresponding to a signal, if the slot in which the kth transmission opportunity is located is the mth transmission opportunity (m < k) of another signal resource set, the priority of the another signal resource set is higher than that of the signal resource set of the signal; optionally, whether the transmission opportunity of a signal is a transmission opportunity satisfying 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 satisfying the transmission condition is determined according to the transmission opportunity corresponding to the first set of signal resources. Optionally, if a signal with higher priority than a signal corresponding to a signal resource set overlaps with a signal time domain symbol corresponding to the signal resource set in a time slot in which a transmission opportunity corresponding to the signal resource set is located, the transmission opportunity corresponding to the signal resource set is not a transmission opportunity in which signal resources (signals corresponding to the signal resources) in the signal resource set satisfy a transmission condition. For example, a transmission opportunity corresponding to an SRS resource set is in a slot, all SRS resources included in the SRS resource set are in 10 th and/or 11 th symbols, and the base station schedules a signal with higher priority than a signal corresponding to the SRS resource set in the 10 th symbol of the slot, so that a signal with higher priority than the signal corresponding to the SRS resource set overlaps with a signal time domain symbol corresponding to the SRS resource set in the slot where the transmission opportunity is located, and the transmission opportunity is not an opportunity satisfying a transmission condition;

The priority of the signal in the time slot in which the transmission opportunity satisfying the transmission condition is located is equal to or lower than the signal (i.e., the priority of the signal in the time slot in which the transmission opportunity satisfying the transmission condition is located is equal to or lower than the signal); for example, a transmission opportunity corresponding to the signal occupies 10 th and 11 th symbols in a time slot, the base station schedules a signal with higher priority than the signal in the 9 th symbol of the time slot, although there is no overlap on the symbols, the transmission opportunity has a signal with higher priority than the signal in the time slot, and the transmission opportunity is not an opportunity to satisfy the transmission condition;

the time slot in which the transmission opportunity meeting the transmission condition is positioned is the time slot except for another signal resource set or signal resource used for transmitting the trigger signaling trigger; for example, when determining whether a transmission opportunity of an SRS is a transmission opportunity satisfying the transmission condition, if the slot in which the transmission opportunity is located has been determined to transmit another SRS resource set triggered by the trigger signaling, the transmission opportunity is not a transmission opportunity satisfying the transmission condition. Optionally, the transmission opportunity in the slot of another SRS resource set that has been determined to transmit the trigger signaling trigger is directly determined as not being a transmission opportunity satisfying the transmission condition; or,

And the time domain symbol corresponding to the signal in the time slot of the transmission opportunity meeting the transmission condition is a time domain symbol except for another signal resource set or signal resource used for transmitting the trigger signaling trigger.

In this embodiment, the signal in which the time domain symbol of the signal at least partially overlaps in the time slot in which the transmission opportunity satisfying the transmission condition is located, the priority of which is equal to or lower than the signal includes: partially overlapping or fully overlapping.

In this embodiment, multiple implementation manners for determining whether one or more of the multiple transmission opportunities meet the transmission condition according to the priority of the signal are provided, and in actual use, one of the multiple transmission opportunities may be selected, or multiple combinations of the multiple transmission opportunities may be selected for use, and one or more of the four items of (i) configuration of uplink and downlink patterns, (ii) time interval between triggering signaling and signal transmission, (iii) requirement of time window between triggering signaling and signal transmission, (iv) time slot offset value configured for a signal resource set through which the signaling triggering signal passes may be used in combination.

For example, an example of the combined use according to the priority of the signal and the configuration of the (r) uplink and downlink patterns may be:

If a time slot comprises at least one uplink or flexible symbol configured by high-level signaling and no signal with higher priority than the signal exists on the time slot, the time slot is the time slot meeting the transmission condition;

for example, an example of using the combination of the priority of the signal and the time interval of triggering signaling and signal transmission may be:

if a time slot is a time slot meeting a first time requirement and a signal with higher priority than the signal does not exist on the time slot, the time slot is a time slot meeting a transmission condition; the first time requirement is as follows: the time interval between the channel carrying the trigger signaling and the symbol of the first signal resource is not less than a first minimum time requirement.

Based on the content of the foregoing embodiment, in this embodiment, determining whether one or more of the multiple transmission opportunities satisfies a transmission condition according to the time interval between the trigger signaling and the signal transmission includes: the time slot in which the transmission opportunity meeting the transmission condition is located meets a first time interval condition; the first time interval condition comprises: and the time interval between the trigger signaling and the signal transmission meets a first minimum time requirement, wherein the time interval between the trigger signaling and the signal transmission is the time interval between a channel carrying the trigger signaling and a symbol of a signal resource of the signal in the time slot. For example, the trigger signaling is DCI, the signal is SRS, and for a certain slot, the time interval between the trigger signaling and the SRS signal transmission is: the time interval between the last symbol of the PDCCH carrying the DCI triggering the SRS resource and the first symbol of the SRS resource of the SRS signal in this slot.

Optionally, it is determined whether a time slot in which one transmission opportunity is located satisfies a first time interval condition, and if not, the transmission opportunity does not satisfy the transmission condition. Optionally, if the timeslot in which one transmission opportunity is located satisfies the first time interval condition, the transmission opportunity satisfies the transmission condition. Optionally, if other conditions (for example, priority requirement, etc.) exist, 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 the transmission opportunity is the transmission opportunity that satisfies the transmission conditions.

In this embodiment, the time slot in which the transmission opportunity satisfying the transmission condition is located needs to satisfy a first minimum time requirement that a time interval between the trigger signaling and the signal transmission satisfies, where the satisfying of the first minimum time requirement includes at least one of the following: greater than or equal to a pre-agreed value; the maximum value of the minimum time requirements corresponding to all the signal resources triggered by the trigger signaling is greater than or equal to; the minimum time requirement corresponding to the signal resource set through which the signal is triggered by the trigger signaling is greater than or equal to; the maximum value of the minimum time requirements corresponding to all the signal resource sets triggered by the trigger signaling is greater than or equal to; and the maximum value is greater than or equal to the maximum value in the minimum time requirements corresponding to the usage types of all the signal resource sets triggered by the trigger signaling.

For example, the trigger signaling is DCI, the signal is SRS, and optionally, the first minimum time requirement is: greater than a value agreed in advance by the base station and the UE;

optionally, the first minimum time requirements corresponding to different SRS resources may be different;

for example, DCI triggers N SRS resources, denoted S respectively₁，…,S_NTheir respective minimum time requirements are not less than k₁,…,k_NI.e. SRS resource S_mThe corresponding minimum time requirement is not less than k_m. SRS resource S_nCorresponding first minimum time requirement is not less than k_n；

Optionally, the first minimum time requirements corresponding to different SRS resource sets are different;

for example, the DCI triggers N SRS resource sets, denoted S respectively₁，…,S_NTheir corresponding minimum time requirements are: not less than k₁,…,k_NI.e. set of SRS resources S_mThe corresponding minimum time requirement is not less than k_mM is equal to {1, …, N }. By being configured in the SRS resource set S_mThe triggered SRS has a first minimum time requirement of not less than k_m，m∈{1,…,N}；

Optionally, the first minimum time requirement is not less than a maximum value in first time intervals corresponding to all SRS resources triggered by the DCI;

for example, DCI triggers N SRS resources, denoted S respectively₁，…,S_NTheir corresponding first time intervals are: k is a radical of formula ₁,…,k_NI.e. S_mCorresponding to a minimum time interval of k_mM is equal to {1, …, N }. The first minimum time requirement is not less than max k₁,…,k_NI.e. not less than k₁,…,k_NMaximum value of (1);

optionally, the first time interval corresponding to one SRS resource is: the minimum time interval between the last symbol of the PDCCH carrying the DCI triggering the SRS resource and the first symbol of the SRS resource;

optionally, a first time interval corresponding to one SRS resource is predetermined by the base station and the terminal;

optionally, the first minimum time requirement is not less than a maximum value in first time intervals corresponding to all SRS resource sets triggered by the DCI;

for example, the DCI triggers N SRS resource sets, denoted S respectively₁，…,S_NTheir corresponding minimum time intervals are: k is a radical of formula₁,…,k_NI.e. S_mCorresponding first time interval is k_mM is equal to {1, …, N }. The first minimum time requirement is not less than max k₁,…,k_NI.e. not less than k₁,…,k_NMaximum value of (1);

optionally, the first time interval corresponding to one SRS resource set is: the minimum time interval is between the last symbol of the PDCCH carrying the DCI triggering the SRS resource set and the first symbol of all symbols of SRS resources in the SRS resource set;

optionally, a first time interval corresponding to one SRS resource set is predetermined by the base station and the terminal;

Optionally, the first minimum time requirement is a maximum value in a first time interval corresponding to usage types of all first SRS resource sets triggered by the DCI;

for example, the DCI triggers N SRS resource sets, denoted S respectively₁，…,S_NThe usage types corresponding to the SRS resource sets are U types in total, and the first time intervals corresponding to the U usage types are respectively: k is a radical of₁,…,k_UThen the first minimum time requirement is not less than max k₁,…,k_UI.e. not less than k₁,…,k_UMaximum value of (1);

optionally, the first time interval corresponding to one SRS resource set type is predetermined by the base station and the terminal.

a, the time interval between the time slot of the transmission opportunity meeting the transmission condition and the time slot of the trigger signaling is less than or equal to a second preset value corresponding to the time window requirements of the transmission of the trigger signaling and the transmission of the signal;

b, the time slot of the transmission opportunity meeting the transmission condition meets the condition that the time interval between the signal resource symbol included by the signal and the channel carrying the trigger signaling is less than or equal to a third preset value corresponding to the time window requirement of the transmission of the trigger signaling and the transmission of the signal; or, the time slot in which the transmission opportunity meeting the transmission condition is located meets the condition that the time interval between the channel carrying the trigger signaling and the symbol of the signal resource included in the first signal resource set is less than or equal to a third preset value corresponding to the time window requirement of the transmission of the trigger signaling and the transmission of the signal;

Optionally, a time slot in which the transmission opportunity meeting the transmission condition is located meets a condition that a time interval between a last symbol of a channel carrying the trigger signaling and a last symbol of a signal resource included in the signal or the first signal resource set is less than or equal to a third preset value corresponding to a time window requirement of transmission of the trigger signaling and transmission of the signal.

Optionally, a time slot in which the transmission opportunity meeting the transmission condition is located meets a condition that a time interval between a first symbol of a channel carrying the trigger signaling and a last symbol of a signal resource included in the signal or the first signal resource set is less than or equal to a third preset value corresponding to a time window requirement of transmission of the trigger signaling and transmission of the signal.

In this embodiment, when it is defined that signal transmission needs to be within a given time window, the time slot (the time slot in which the transmission opportunity satisfying the transmission condition is located) may be determined as follows: the time interval between the last symbol of the channel carrying the trigger instruction and the last symbol of the resource is not more than a given value; or the time interval between the time slot and the time slot of the trigger signaling is not greater than a given value. Optionally, the given value is a fixed value. Such as protocol conventions, or base station indications. Optionally, the given value is a function of a timeslot offset value configured for the signal resource set by the base station through signaling. The signaling may be RRC signaling, MAC-CE signaling, DCI signaling, or a slot offset value obtained from a combination thereof. Optionally, the given value is determined according to an uplink and downlink configuration of the UE (e.g., determined according to DL-UL-transmissionpermission in an RRC signaling TDD-UL-DL-Pattern). Optionally, when the UE is configured with a plurality of TDD-UL-DL-patterns in one carrier, the UE is determined according to a maximum value of DL-UL-transmissionpermission in the plurality of TDD-UL-DL-patterns.

when one of the multiple transmission opportunities and the transmission opportunity of another signal resource set except the first signal resource set triggered by the trigger signaling have overlapped time domain symbols, determining whether the one transmission opportunity meets the transmission condition according to time slot offset values respectively configured for the two signal resource sets by the network equipment; wherein the first set of signal resources is a set of signal resources through which the trigger signaling triggers the signal. For example, assuming that the trigger signaling is DCI and the signal is SRS, the transmission opportunity of SRS is determined by the transmission opportunity of its corresponding SRS resource set. If an SRS resource set corresponding to an SRS signal is an SRS resource set 1, and a transmission opportunity corresponding to the SRS resource set 1 and a transmission opportunity of the SRS resource set 2 overlap on a time domain symbol of a time slot, determining which SRS resource set the time slot is a transmission opportunity according to a time slot offset value respectively configured by the network device for the SRS resource set 1 and the SRS resource set 2. For example, when there is an overlapping time domain symbol between one of the multiple transmission opportunities and a transmission opportunity of another signal resource set other than the first signal resource set triggered by the trigger signaling, the transmission opportunity of the signal resource set with the smallest slot offset value configured by the network device is a transmission opportunity satisfying the transmission condition, and if the slot offset values configured by the network device for SRS resource set 1 and SRS resource set 2 are 1 and 2, respectively, then this transmission opportunity of SRS resource set 1 is a transmission opportunity satisfying the transmission condition, and this transmission opportunity of SRS resource set 2 is not a transmission opportunity satisfying the transmission condition.

Optionally, the kth transmission slot (kth transmission opportunity) is a slot corresponding to a slot that is delayed by k-1 times from a slot determined by the UE according to the first slot offset signaling configured by the network device for the SRS resource set, and that satisfies the first condition. Wherein the second slot offset value may be protocol-agreed or indicated by the network device.

For example, the trigger signaling is DCI, the signal is SRS, and optionally, the network device indicates a slot offset value for the SRS resource set corresponding to the signal through a first slot offset value configured by RRC signaling (not set to t)₁) The first time slot deviant t is indicated in the trigger signaling₂UE according to t₁And t₂Determined by a common determined time slotThe transmission opportunity. For example, the transmission opportunity is t from the time slot where the DCI is located₂Each time slot is a period, the t-th time slot in each period₁A time slot (or a first time slot). The network device may indicate the timeslot offset value through RRC signaling, MAC-CE signaling, or DCI, and optionally, the first timeslot offset value is indicated by DCI carrying the trigger signaling.

Adjacent ones of the plurality of transmission opportunities are separated by a second slot offset value of slots; or, adjacent transmission opportunities in the plurality of transmission opportunities are separated by a third slot offset value, which is a slot satisfying the first condition; the time slot meeting the first condition is determined according to at least one of the priority of the signal, the configuration of the uplink and downlink patterns, the time interval requirement of the signal and the transmission of the trigger signaling, the time window requirement of the signal transmission and the transmission of the trigger signaling, or the first time slot offset signaling.

Based on the content of the foregoing embodiment, in this embodiment, the second slot offset value or the third slot offset value is at least one of the following:

and determining a value according to the usage type of the signal resource set.

In this embodiment, it should be noted that the second slot offset value or the third slot offset value may be indicated independently, and may be the same or different.

And the transmission time slot of the signal resource set does not exceed the time window corresponding to the signal resource set. For example, a time difference between a transmission slot of a set of signal resources relative to a transmission slot of a trigger signaling triggering the set of signal resources is not greater than a preset value. The preset value can be a value indicated by the network equipment through signaling; a value of the agreement contract; a value related to numerology of the BWP in which the trigger signaling is located; a value related to numerology of a BWP in which the set of signal resources resides; or a value related to the usage type of the set of signal resources, etc. Alternatively, the termination conditions for different sets of signal resources are independent, i.e. the termination conditions for different sets of signal resources may be the same or different. Optionally, the termination condition of all signal resource sets triggered by the same DCI is the same. Optionally, the termination condition of all signal resource sets of the same usage type is the same.

The following description takes an aperiodic signal as an SRS as an example. The base station typically configures the SRS through SRS resources and sets of SRS resources. And when triggering the aperiodic SRS transmission, the base station triggers the SRS resource set through the DCI, and then the UE transmits the SRS corresponding to the SRS resource in the triggered SRS resource set.

An example of the algorithm of the present embodiment is: the UE determines a first transmission slot (a first transmission opportunity) of each SRS resource set triggered by the DCI, and determines, for each SRS resource set, whether the SRS resource set can perform transmission in the corresponding first transmission slot (the first transmission opportunity) (that is, determines, for each SRS resource set, whether the first transmission opportunity of the SRS resource set is the first transmission opportunity, where the first transmission opportunity is a transmission opportunity satisfying a transmission condition);

for an SRS resource set that can be transmitted in a corresponding first transmission slot (the first transmission opportunity is a first transmission opportunity), the UE performs its corresponding SRS transmission in its corresponding first transmission slot;

for the SRS resource set which can not be transmitted in the corresponding first transmission slot (the first transmission opportunity is not the first transmission opportunity), the UE determines the corresponding second transmission slot (the second transmission opportunity), if the SRS resource set can be transmitted in the corresponding second transmission slot (the second transmission opportunity is the first transmission opportunity), the UE performs the transmission of the corresponding SRS in the second transmission slot; otherwise (the second transmission opportunity is not the first transmission opportunity), the UE does not transmit its corresponding SRS.

In the foregoing embodiments, optionally, it may be determined whether a transmission opportunity in one timeslot is a transmission opportunity that satisfies a transmission condition according to a condition that should be satisfied by a timeslot in which the transmission opportunity that satisfies the transmission condition is located.

By popularizing the algorithm, the method can be popularized to the scene that SRS transmission corresponding to the SRS resource set has more transmission opportunities. The method provided by the embodiment is described in detail through a specific processing procedure as follows:

the method comprises the following steps: the UE determines respective first transmission slots (first transmission opportunities) of the SRS resource sets triggered by the DCI, and determines, for each SRS resource set, whether the SRS resource set can transmit in the corresponding first transmission slot (that is, determines, for each SRS resource set, whether the first transmission opportunity of the SRS resource set is the first transmission opportunity); let k equal to 1;

step two: for the SRS resource set that can be transmitted in the corresponding kth transmission slot (i.e. the kth transmission opportunity is the first transmission opportunity), the UE transmits its corresponding SRS in the corresponding kth transmission slot; otherwise (that is, the kth transmission opportunity is not the first transmission opportunity), if k is equal to k +1, if the termination condition is satisfied, the UE does not perform transmission of the SRS corresponding to the non-transmitted SRS resource set any more, and if the termination condition is not satisfied, the step two is performed.

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

Optionally, if a slot has been determined to be used for transmitting a certain set of SRS resources, the slot is no longer the first transmission opportunity of other sets of SRS resources for which the slot offset value of the RRC signaling configuration is different.

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

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

Optionally, if all the symbols configured for all the SRS resources in one SRS resource set are uplink symbols and/or flexible symbols in one slot, the slot is a first transmission opportunity that can be used for the SRS resource set.

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

Optionally, if all the symbols configured for all the SRS resources in one SRS resource set are uplink symbols and/or flexible symbols in one slot, and the slot is not determined to be used for transmitting other SRS resource sets with different slot offset values configured for RRC signaling, the slot is the first transmission opportunity of the SRS resource set.

The following explains the manner of determining the first transmission slot (first transmission opportunity) and the kth transmission slot (kth transmission opportunity).

First transmission time slot (first transmission opportunity)

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

For example, the network device configures a slot offset value for one SRS resource set, where the slot offset value is used to indicate an offset value of a transmission slot of an SRS resource in the SRS resource set relative to a slot of DCI triggering the SRS resource set. And the UE determines a transmission slot as a first transmission slot (first transmission opportunity) according to the slot in which the DCI triggering the SRS resource set is positioned and the slot offset value.

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

Kth transmission time slot (k >1) (kth transmission opportunity)

Optionally, the kth transmission slot (kth transmission opportunity) of one SRS resource set is: and the UE determines the transmission time slot jointly according to the first time slot offset signaling and the second time slot offset value configured for the SRS resource set by the network equipment. The second timeslot offset value may be a timeslot offset value indicated by the network device (through RRC signaling/MAC-CE signaling/DCI signaling, etc.), may also be a value agreed by a protocol, and may also be a value determined by the terminal according to a certain rule.

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

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

As shown in fig. 3, a flowchart of steps of a signal transmission method applied to a network device side provided in the embodiment of the present application is shown, where the method includes the following steps:

step 301: determining a transmission location of a signal from a transmission opportunity of the signal;

step 302: and sending a trigger signaling for triggering the signal transmission or reception, wherein the trigger signaling has an association relation 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 position includes: receiving the signal at the transmission location. Optionally, the receiving the signal according to the transmission position includes: the signal is received on a portion of the symbols of the transmission location.

In this embodiment, it may be understood that the network device may send a trigger signaling for triggering transmission or reception of the signal, where the trigger signaling has an association relationship with a transmission position of the signal and/or the transmission opportunity.

It should be noted that the present embodiment is applicable to aperiodic uplink signals (e.g., sounding Reference signal SRS), aperiodic downlink signals (e.g., CSI-rs (channel State Information Reference signal), CSI-im (channel State Information Interference measurement) Reference signals, etc.), semi-persistent uplink signals, semi-persistent downlink signals, etc. For the sake of illustrative description, the following embodiments of the present application will be described by using aperiodic SRS. Therefore, the embodiment can solve the problem that the triggering and the sending of the non-periodic signal resource are not flexible in the wireless communication system.

According to the signal transmission method provided by the embodiment of the application, the transmission position of the signal is determined from a plurality of transmission opportunities of the signal, and the trigger signaling for triggering the signal transmission or reception is sent according to the transmission position of the signal.

Based on the content of the foregoing embodiments, 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 a transmission location of a signal from a plurality of transmission opportunities of the signal includes:

In this embodiment, whether one or more of the multiple transmission opportunities meet the transmission condition is sequentially determined according to the trigger signaling until N transmission opportunities meeting the transmission condition are determined or until a termination condition is reached, where N is an integer greater than or equal to 1, it should be noted that, here, the sequence is not necessarily all the transmission opportunities, and may be part or all the transmission opportunities.

In this embodiment, the value of N may be set as needed, for example, optionally, N is 1; optionally, N ═ 2; optionally, N is a numerical value indicated by the base station; optionally, N is a predefined number. For example, a value agreed upon by the protocol. Optionally, N is a numerical value reported by the terminal device.

Based on the content of the foregoing embodiment, in this embodiment, the determining whether one or more of the multiple transmission opportunities satisfy a transmission condition until determining N transmission opportunities satisfying the transmission condition or until reaching a termination condition includes:

determining whether a kth transmission opportunity of a set of signal resources through which the signal is triggered by the trigger signaling is a transmission opportunity satisfying the transmission condition; if yes, determining whether N transmission opportunities meeting the transmission condition or a termination condition is reached; if the kth transmission opportunity of the signal resource set through which the signal is triggered by the trigger signaling is not the transmission opportunity of the transmission condition or N transmission opportunities meeting the transmission condition are not determined or the termination condition is not met, continuing to determine by taking k as a circulation condition until N transmission opportunities meeting the transmission condition are determined or the termination condition is met; or,

Determining whether a kth transmission opportunity of a signal resource of the signal is a transmission opportunity that satisfies the transmission condition; if yes, determining whether N transmission opportunities meeting the transmission condition or a termination condition is met; if the kth transmission opportunity of the signal resource of the signal is not the transmission opportunity meeting the transmission condition or N transmission opportunities meeting the transmission condition are not determined or the termination condition is not met, taking k as a circulation condition to continue determining until N transmission opportunities meeting the transmission condition are determined or the termination condition is met;

wherein the initial value of k is 1.

In this embodiment, a specific implementation process of determining 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 a termination condition is reached is given, and it can be known from the above description that this embodiment sequentially determines whether each transmission opportunity satisfies the transmission condition, if so, continues to determine whether N transmission opportunities are determined, if so, stops, otherwise, continues to determine until N transmission opportunities are determined. Further, when the termination condition is satisfied, the determination of whether the transmission condition is satisfied is not performed.

Based on the content of the above embodiments, in the present embodiment, it is determined whether one or more of the plurality of transmission opportunities satisfies a transmission condition according to at least one of:

configuring an uplink pattern and a downlink pattern;

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

the priority of the signal; or,

For example, an example of determining the transmission condition based on the (r) uplink and downlink pattern configuration is:

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

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

or,

In this embodiment, it may be understood that, when determining whether one or more of the multiple transmission opportunities satisfies the transmission condition according to the uplink and downlink pattern configuration, there are two cases, namely, uplink and downlink: when a signal is an uplink signal, an uplink symbol and/or a flexible symbol included in a time slot in which a transmission opportunity meeting a transmission condition is located covers all symbols of a signal resource of the signal; optionally, when the signal is an uplink signal, the uplink symbol and/or the flexible symbol included in the time slot in which the transmission opportunity meeting the transmission condition is located covers all the symbols configured for configuring the signal resource of the signal.

And B, when the signal is a downlink signal, the downlink symbol and/or the flexible symbol included in the time slot in which the transmission opportunity meeting the transmission condition is located cover all symbols of the signal resource of the signal. Optionally, when the signal is a downlink signal, the downlink symbol and/or the flexible symbol included in the time slot in which the transmission opportunity meeting the transmission condition is located cover all the symbols configured for configuring the signal resource of the signal.

Similar to the principle of the above embodiments, the difference is that the above embodiments are directed to uplink signals, and the present embodiments are directed to downlink signals.

It is to be understood that the above-mentioned one transmission opportunity may be understood as corresponding to one transmission slot; accordingly, determining the transmission location of the signal from the transmission opportunity of the signal according to the trigger signaling may be understood as: determining a transmission position of the signal from a plurality of transmission time slots of the signal according to the trigger signaling. For the above embodiments, determining whether one or more of the multiple transmission opportunities satisfy the transmission condition according to the uplink and downlink pattern configuration may be implemented in at least the following manners:

if a slot includes at least one uplink or flexible symbol configured by higher layer signaling, the slot is a slot satisfying a first condition; optionally, the high layer signaling is RRC signaling; optionally, the higher layer signaling is MAC-CE signaling. A slot is a slot that satisfies transmission conditions if the uplink and/or flexible symbols included in the slot include all time domain symbols of the signal resources of the signal; for example, assuming that the time domain symbols configured for the signal resources of the signal are the last 2 symbols in a slot, and the last two symbols included in a slot are uplink symbols, the slot is a slot satisfying the first condition; for another example, the time domain symbol configured for the signal resource of the signal is the last 2 symbols in the time slot, and one of the last two symbols included in one time slot is an uplink symbol and one is a flexible symbol, and then this time slot is a time slot that satisfies the first condition; for another example, the time domain symbol configured for the signal resource of the signal is the last 2 symbols in the time slot, and the last two symbols included in one time slot include one downlink symbol, so that the time slot is not a time slot satisfying the first condition;

If the uplink and/or flexible symbol included in a timeslot contains time domain symbols of all signal resources in the signal resource set through which the trigger signaling triggers the signal, the timeslot is a timeslot meeting transmission conditions; for example, it is assumed that the trigger signaling triggers the signal through a signal resource set 1, and this signal resource set includes a signal resource (it is not labeled as signal resource 1) and another signal resource (it is not labeled as signal resource 2) of the signal, and it is assumed that the time domain symbol configured for signal resource 1 is the last 2 symbols in the slot and the time domain symbol configured for signal resource 2 is the last 3 symbols in the slot. If the last 3 symbols included in a slot are uplink symbols, the slot is a slot satisfying a first condition; however, if a slot includes a 3 rd to last symbol which is a downlink symbol and the last two symbols are uplink symbols, the slot is not a slot satisfying the first condition;

if the uplink and/or flexible symbol included in a timeslot contains the time domain symbol configured for all signal resources in all signal resource sets triggered by the trigger signaling, the timeslot is a timeslot satisfying the transmission condition; for example, assuming that the trigger signaling triggers signal resource set 1 and signal resource set 2, which include the time domain symbols for which the signal resources are configured to be 1 st, 2 nd symbols and 4 th, 5 th symbols, respectively, only when all the 1 st, 2 nd, 4 th, 5 th symbols of a slot are uplink symbols, the slot is a slot that satisfies the first condition, otherwise, the slot is not a slot that satisfies the first condition.

a signal in a time slot in which a transmission opportunity satisfying a transmission condition is located, the signal at least partially overlapping a time domain symbol of the signal, has a priority equal to or lower than that of the signal; for example, a transmission opportunity corresponding to the signal occupies 10 th and 11 th symbols in a time slot, the base station schedules a signal with higher priority than the signal in the 10 th symbol of the time slot, and then the signal with higher priority than the signal overlaps with the time domain symbol of the signal in the time slot where the transmission opportunity is located, and the transmission opportunity is not an opportunity meeting the transmission condition;

the priority of the signal which is at least partially overlapped with the signal time domain symbol corresponding to the first signal resource set in the time slot where the transmission opportunity meeting the transmission condition is located is equal to or lower than the signal corresponding to the first signal resource set; optionally, further, there is no signal with higher priority than the signal corresponding to any signal resource set triggered by the trigger signaling in the time slot in which the transmission opportunity meeting the transmission condition is located, and the signal time domain symbol corresponding to the signal resource set overlaps with the signal time domain symbol corresponding to the signal resource set, that is, there is no signal with higher priority than the signal triggered by the trigger signaling in the time slot in which the transmission opportunity meeting the transmission condition is located in all the signal resource sets triggered by the trigger signaling on the time domain symbol of the signal resource; wherein the first set of signal resources is a set of signal resources through which the trigger signaling triggers the signal; optionally, for the kth transmission opportunity of a signal resource set corresponding to a signal, if the slot in which the kth transmission opportunity is located is the mth transmission opportunity (m < k) of another signal resource set, the priority of the another signal resource set is higher than that of the signal resource set of the signal; optionally, whether the transmission opportunity of a signal is a transmission opportunity satisfying 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 satisfying the transmission condition is determined according to the transmission opportunity corresponding to the first set of signal resources. Optionally, if a signal with higher priority than a signal corresponding to a signal resource set overlaps with a signal time domain symbol corresponding to the signal resource set in a time slot in which a transmission opportunity corresponding to the signal resource set is located, the transmission opportunity corresponding to the signal resource set is not a transmission opportunity in which signal resources (signals corresponding to the signal resources) in the signal resource set satisfy a transmission condition. For example, a transmission opportunity corresponding to an SRS resource set is in a slot, all SRS resources included in the SRS resource set are in 10 th and/or 11 th symbols, and the base station schedules a signal with higher priority than a signal corresponding to the SRS resource set in the 10 th symbol of the slot, so that a signal with higher priority than the signal corresponding to the SRS resource set overlaps with a signal time domain symbol corresponding to the SRS resource set in the slot where the transmission opportunity is located, and the transmission opportunity is not an opportunity satisfying a transmission condition;

The priority of a signal in a slot in which a transmission opportunity satisfying the transmission condition is located is equal to or lower than the signal; for example, a transmission opportunity corresponding to the signal occupies 10 th and 11 th symbols in a time slot, the base station schedules a signal with higher priority than the signal in the 9 th symbol of the time slot, although there is no overlap on the symbols, the transmission opportunity has a signal with higher priority than the signal in the time slot, and the transmission opportunity is not an opportunity to satisfy the transmission condition;

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

The time domain symbol corresponding to the signal in the time slot in which the transmission opportunity satisfying the transmission condition is located is a time domain symbol other than another signal resource set or signal resource used for transmitting the trigger signaling trigger (that is, the time domain symbol corresponding to the signal in the time slot in which the transmission opportunity satisfying the transmission condition is located is not determined to be used for transmitting another signal resource set or signal resource used for transmitting the trigger signaling trigger).

In this embodiment, multiple implementation manners for determining whether one or more of the multiple transmission opportunities satisfy the transmission condition according to the priority of the signal are provided, and in actual use, one of them may be selected, or multiple combinations of them may be selected, or one or more of the four items, that is, uplink and downlink pattern configuration, time interval between trigger signaling and signal transmission, time window requirement between trigger signaling and signal transmission, and time slot offset value configured for a signal resource set through which the signaling trigger signal is triggered may be used in combination.

For example, the example of combining and using according to the priority of the signal and the arrangement of the uplink and downlink patterns is as follows:

the time slot in which the transmission opportunity meeting the transmission condition is located meets a first time interval condition; the first time interval condition comprises: and the time interval between the trigger signaling and the signal transmission meets a first minimum time requirement, wherein the time interval between the trigger signaling and the signal transmission is the time interval between a channel carrying the trigger signaling and a symbol of a signal resource of the signal on the time slot. For example, the trigger signaling is DCI, the signal is SRS, and for a certain slot, the time interval between the trigger signaling and the SRS signal transmission is: a time interval between the last symbol of the PDCCH carrying the DCI triggering the SRS resource and the first symbol of the SRS resource of the SRS signal in this slot.

Optionally, it is determined whether a time slot in which a transmission opportunity is located meets a first time interval condition, and if the time slot does not meet the first time interval condition, the transmission opportunity does not meet the transmission condition. Optionally, if the timeslot in which one transmission opportunity is located satisfies the first time interval condition, the transmission opportunity satisfies the transmission condition. Optionally, if other conditions (for example, priority requirement, etc.) exist, if the timeslot in which a transmission opportunity is located satisfies the first time interval condition, and at the same time, satisfies other conditions, then the transmission opportunity is a transmission opportunity that satisfies the transmission conditions.

In this embodiment, the time slot in which the transmission opportunity meeting the transmission condition is located needs to meet a first minimum time requirement that a time interval between the trigger signaling and the signal transmission meets, where the meeting of the first minimum time requirement includes at least one of the following: greater than or equal to a pre-agreed value; the maximum value of the minimum time requirements corresponding to all the signal resources triggered by the trigger signaling is greater than or equal to; the minimum time requirement corresponding to the signal resource set through which the signal is triggered by the trigger signaling is greater than or equal to; the maximum value of the minimum time requirements corresponding to all the signal resource sets triggered by the trigger signaling is greater than or equal to; and the maximum value is larger than or equal to the maximum value in the minimum time requirements corresponding to the usage types of all the signal resource sets triggered by the trigger signaling.

for example, DCI triggers N SRS resources, denoted S respectively₁，…,S_NTheir respective minimum time requirements are not less than k₁,…,k_NI.e. SRS resource S_mThe corresponding minimum time requirement is not less than k_mM is equal to {1, …, N }. Then SRS resource S_mCorresponding first minimum time requirement is not less than k_m，m∈{1,…,N}；

for example, DCI triggers N SRS resource sets, denoted S respectively₁，…,S_NAnd the corresponding minimum time requirements are as follows: not less than k₁,…,k_NI.e. set of SRS resources S_mThe corresponding minimum time requirement is not less than k_mM is equal to {1, …, N }. By being configured in the SRS resource set S_mThe triggered SRS corresponds to a first minimum time requirement of not less than k_m，m∈{1,…,N}；

for example, the DCI triggers N SRS resources, denoted S respectively₁，…,S_NTheir corresponding first time intervals are: k is a radical of ₁,…,k_NI.e. S_mCorresponding to a minimum time interval of k_mM is equal to {1, …, N }. The first minimum time requirement is not less than max k₁,…,k_NI.e. not less than k₁,…,k_NMaximum value of (1);

optionally, the first time interval corresponding to one SRS resource is predetermined by the base station and the terminal;

for example, DCI triggers N SRS resource sets, denoted S respectively₁，…,S_NTheir corresponding minimum time intervals are: k is a radical of formula₁,…,k_NI.e. S_mCorresponding first time interval is k_mM is equal to {1, …, N }. The first minimum time requirement is not less than max k₁,…,k_NI.e. not less than k₁,…,k_NMaximum value of (2);

optionally, the first time interval corresponding to one SRS resource set is: the minimum time interval is between the last symbol of the PDCCH carrying the DCI triggering the SRS resource set and the first symbol of all the symbols of the SRS resources in the SRS resource set;

for example, the DCI triggers N SRS resource sets, denoted S respectively₁，…,S_NThe usage types corresponding to the SRS resource sets are U types in total, and the first time intervals corresponding to the U usage types are respectively: k is a radical of₁,…,k_UThen the first minimum time requirement is not less than max k₁,…,k_UI.e. not less than k₁,…,k_UMaximum value of (2);

the time slot of the transmission opportunity meeting the transmission condition meets a second time interval condition; the second time interval condition includes: the time intervals of the symbols of all signal resources in the channel carrying the trigger signaling and the first signal resource set all meet a first minimum time requirement;

For example, the trigger signaling is DCI, the signal is SRS, and optionally, if a slot is a slot that satisfies the following conditions, the slot is a slot that satisfies transmission conditions: and the time interval between the last symbol of the PDCCH carrying the DCI and the first symbol of all the symbols of the SRS resource set/SRS resource triggered by the DCI meets the first minimum time requirement.

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

the time interval between the channel carrying the trigger signaling and all signal resource sets and/or all symbols of signal resources triggered by the trigger signaling meets a first minimum time requirement.

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

In this embodiment, the time intervals between the channel carrying the trigger signaling and all signal resource sets and/or symbols of all signal resources triggered by the trigger signaling all satisfy a first minimum time requirement, which includes:

and the time intervals among the channels carrying the trigger signaling, all signal resource sets triggered by the trigger signaling and all symbols of the signal resources meet a first minimum time requirement.

As can be seen from the above description, in the several embodiments, when determining whether one or more of the multiple transmission opportunities satisfies the transmission condition according to the time interval between the trigger signaling and the signal transmission, specific implementation manners may include the following:

a slot is a slot that satisfies the transmission condition if it is a slot that satisfies the following condition: the time interval between the signal transmission corresponding to the channel carrying the trigger signaling and all signal resource sets/all signal resources triggered by the trigger signaling meets the first minimum time requirement;

For example, triggering signaling triggers N signal resources, respectively denoted S₁，…,S_NTheir respective minimum time requirements are not less than k₁,…,k_NI.e. signal resource S_mThe corresponding minimum time requirement is not less than k_mM is equal to {1, …, N }. Then signal resource S_mCorresponding first minimum time requirement is not less than k_m，m∈{1,…,N}。

For example, triggering signaling triggers N sets of signal resources, denoted S respectively₁，…,S_NTheir correspondingThe minimum time requirements are respectively: not less than k₁,…,k_NI.e. a set S of signal resources_mThe corresponding minimum time requirement is not less than k_mM is equal to {1, …, N }. By being configured in the signal resource set S_mThe triggered signal has a first minimum time requirement of not less than k_m，m∈{1,…,N}。

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

For example, triggering signaling triggers N signal resources, respectively denoted S ₁，…,S_NTheir corresponding first time intervals are: k is a radical of₁,…,k_NI.e. S_mCorresponding to a minimum time interval of k_mM is equal to {1, …, N }. The first minimum time requirement is not less than max k₁,…,k_NI.e. not less than k₁,…,k_NOf (2) is calculated.

For example, triggering signaling triggers N sets of signal resources, respectively denoted S₁，…,S_NTheir corresponding minimum time intervals are: k is a radical of formula₁,…,k_NI.e. S_mCorresponding first time interval is k_mM is equal to {1, …, N }. The first minimum time requirement is not less than max k₁,…,k_NI.e. not less than k₁,…,k_NMaximum value of (2);

for example, triggering signaling triggers N sets of signal resources, respectively denoted S₁，…,S_NThe usage types corresponding to the signal resource sets are U, and the first time intervals corresponding to the U usage types are respectively: k is a radical of formula₁,…,k_UThen the first minimum time requirement is: not less than max k₁,…,k_UI.e. not less than k₁,…,k_UOf (2) is calculated.

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

Based on the content of the foregoing embodiments, in this embodiment, determining whether one or more of the plurality of transmission opportunities satisfies a transmission condition according to the time window requirements of the transmission of the trigger signaling and the transmission of the signal includes at least one of the following:

when one transmission opportunity in the plurality of transmission opportunities and the transmission opportunity of another signal resource set except the first signal resource set triggered by the trigger signaling have overlapped time domain symbols, determining whether the one transmission opportunity meets a transmission condition according to time slot offset values respectively configured for the two signal resource sets; wherein the first set of signal resources is a set of signal resources through which the trigger signaling triggers the signal.

For example, the triggering signaling is DCI, the signal is SRS, and optionally, if all symbols configured for all SRS resources in one SRS resource set are uplink symbols or flexible symbols in one slot, and the slot is not determined to be used for transmitting other SRS resource sets with different slot offset values configured for RRC signaling, the slot is a transmission opportunity of the SRS resource set that satisfies the transmission condition.

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

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

Based on the content of the foregoing embodiment, in this embodiment, determining the transmission opportunity according to a timeslot offset signaling indicated by a signal resource set through which the signal is triggered for the trigger signaling includes:

For example, the triggering signaling is DCI, the signal is SRS, and optionally, the network device configures a slot offset value for one SRS resource set, where the slot offset value is used to indicate an offset value of a transmission slot of an SRS resource in the SRS resource set relative to a slot of the DCI triggering the SRS resource set. And the UE determines a transmission slot as a first transmission slot (first transmission opportunity) according to the slot in which the DCI triggering the SRS resource set is positioned and the slot offset value. The network device may indicate the timeslot offset value through RRC signaling, MAC-CE signaling, or DCI, and optionally, the first timeslot offset value is indicated by DCI carrying the trigger signaling.

Based on the content of the above embodiment, in the present embodiment, one transmission opportunity corresponds to one transmission slot; determining a transmission location of a signal from a plurality of transmission opportunities of the signal, comprising:

A transmission location of the signal is determined from a plurality of transmission slots. It should be noted that the signal transmission method applied to the network device provided in this embodiment is similar to the signal transmission method applied to the terminal device in principle, and for a specific example, reference may be made to the description of the signal transmission method applied to the terminal device, and details are not described here again.

The present application will be specifically described below with reference to specific examples.

In the present embodiment, the maximum 2 transmission opportunities per SRS resource set are taken as an example for describing the embodiment, and it is extended that there are more transmission opportunities per SRS resource set.

And the base station sends configuration information of the SRS resource set to the UE, wherein the configuration information comprises a time slot deviant corresponding to the SRS resource set.

And the base station sends DCI signaling triggering the UE to transmit the aperiodic SRS resource to the UE in the time slot n. And triggering the UE to transmit the SRS corresponding to the M SRS resource sets by the DCI signaling (M is an integer greater than or equal to 1). Optionally, the DCI signaling may be DCI format 0_1, DCI format 0_2, DCI format 1_1, DCI format 1_2, or DCI format 2_ 3.

After receiving the DCI signaling, the UE determines first transmission slots (first transmission opportunities) corresponding to the M SRS resource sets triggered by the DCI. Assuming that the DCI triggered SRS resource set is denoted S _kSRS resource set S_kThe first transmission time slot of (1) is from the time slot n of the DCI to the s th time slot_kAnd a time slot. S is_kSet S for SRS resources_kIs configured with the configuration information (k e {1, …, M }).

Fig. 4 shows an example where M is 4, where D in fig. 4 denotes a downlink slot and U denotes an uplink slot. In this example, S₁,S₂,S₃,S₄Corresponding s₁,s₂,s₃,s₄Respectively 2, 3, 10 and 5. Then S₁,S₂,S₃,S₄The corresponding first transmission time slots are time slots n +2, n +3, n +10, n +5, respectively.

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

Optionally, if all the configured symbols of one SRS resource set are uplink symbols or flexible symbols in one slot, the slot is a slot in which the SRS resource set can be transmitted. A transmission opportunity is the first transmission opportunity if the time slots it comprises can satisfy the above conditions. The first transmission opportunity in the present embodiment refers to a transmission opportunity that satisfies a transmission condition.

Thus, since slot n +2 and slot n +10 are both uplink slots (all symbols are uplink symbols), they are each a transmission S₁And S₃Since the slot n +3 and the slot n +5 are downlink slots (all symbols are downlink symbols), the slot n +3 is not S₂The first transmission opportunity of (1), time slot n +5 is not S₄The first transmission opportunity.

UE determination S₂And S₄The corresponding second slot offsets are delayed by 4 and 5 slots, respectively, on the basis of the first transmission slot (in this embodiment, the UE is determined from information indicated by the base station). The UE determines S₂And S₄Are n +3+ 4-n +7 and n +5+ 5-n +10, respectively. Since time slot n +10 has been used to transmit S₄It is therefore no longer the first transmission opportunity for any other set of SRS resources. The uplink time slot n +7 is S₂Is the available time slot of S₂The first transmission opportunity. The UE transmits S in slot n +7₂UE does not transmit S₄。

Therefore, by the mode of the scheme, the transmission opportunity of the non-periodic SRS resource is increased, the expense of triggering the SRS resource by the DCI is reduced, and the flexibility of scheduling and transmitting the SRS resource is increased. In the scheme, the SRS transmission opportunity is not reserved resources and can be used for transmitting other signals when the SRS transmission opportunity is determined not to be used for SRS resource transmission.
