[0026] In the embodiments of this application, the term "and / or" describes the relationship between associated objects, indicating that three relationships can exist. For example, A and / or B can represent three cases: A alone, A and B simultaneously, and B alone. The character " / " generally indicates that the preceding and following associated objects have an "or" relationship.

[0027] In the embodiments of this application, the term "multiple" refers to two or more, and other quantifiers are similar.

[0028] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of this application, and not all of the embodiments. Based on the embodiments of this application, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of this application.

[0029] It should be noted that in the prior art, the transmission timing specification restricts the time-domain transmission location, so that signal transmission is carried out through a fixed time-domain transmission location.

[0030] Taking Sounding Reference Signaling (SRS) as an example, in the 3rd Generation Partnership Project (GPP) New Radio (NR)... rdIn the Generation Partnership Project New Radio (3GPP NR) system, base stations can configure aperiodic SRS (or Channel State Information Reference Signal, or CSI-RS) resource sets and aperiodic SRS (or CSI-RS) resources for user equipment (UE) such as terminal equipment via Radio Resource Control (RRC) signaling. The transmission of aperiodic SRS (or CSI-RS) resources is triggered through the SRSrequest field (or CSIreporting field) in Downlink Control Information (DCI) signaling. Because the configuration via RRC signaling is semi-static, the flexibility of signal transmission configured through RRC signaling is extremely low. Furthermore, in Test Driven Development (TDD) mode, if the transmission time unit n+noffset is a downlink transmission time unit (or uplink transmission time unit), then the transmission time unit n+noffset cannot transmit SRS (or CSI-RS), and the UE will no longer transmit that SRS (or CSI-RS). To avoid SRS (or CSI-RS) transmission failure, this will limit the time-domain transmission location of DCI sent by the base station, thereby reducing the flexibility of triggering SRS (or CSI-RS) transmission via DCI.

[0031] For example, such as Figure 1 As shown, the uplink and downlink transmission time units are configured in a DDFUU manner every five transmission time units. Here, D represents the downlink transmission time unit, U represents the uplink transmission time unit, and F represents a flexible transmission time unit containing both uplink and downlink symbols. Within these five transmission time units, the transmission of the Physical Downlink Shared Channel (PDSCH) triggering aperiodic SRS and all possible positions of the PDSCH and SRS during aperiodic SRS transmission are completed. Each row represents one transmission position of the PDSCH and SRS at an SRS offset, and each column represents one transmission time unit.

[0032] according to Figure 1 It can be seen that when the offset of the trigger transmission time unit is 1, the PDCCH used to trigger the non-periodic SRS can only be transmitted in transmission time unit 1 or transmission time unit 2, and cannot be transmitted in other time slots. The SRS can also only be transmitted in transmission time unit 2 and transmission time unit 3.

[0033] Therefore, the signal transmission method proposed in this application no longer restricts signal transmission to a fixed time-domain transmission location, thus improving the flexibility of the signal transmission process.

[0034] Figure 2 This is a schematic diagram according to the first embodiment of this application. (See diagram below.) Figure 2 As shown, taking a terminal device as the executing entity, the signal transmission method proposed in the embodiments of this application will be explained and described, specifically including the following steps:

[0035] S101. Receive trigger signaling sent by the network device. The trigger signaling is used to instruct the transmission or reception of target signals corresponding to multiple reference signal resources and / or target signals corresponding to multiple sets of reference signal resources.

[0036] The triggering signaling received from the network device can be DCI signaling. DCI refers to downlink control information carried by the Physical Downlink Control Channel (PDCCH) and sent to the UE by network devices such as base stations (eNBs). It should be noted that this application does not limit the format of the DCI signaling; it can be selected according to the actual situation. For example, the DCI signaling format can be DCI format0_1, DCI format 0_2, DCI format 1_1, DCI format 1_2, or DCI format 2_3, etc.

[0037] The reference signal resource can be either an uplink reference signal resource or a downlink reference signal resource; the reference signal resource set can be a set consisting of the time-domain transmission location of the target signal corresponding to the uplink reference signal resource and / or the downlink reference signal resource. Optionally, the reference signal resource can be an SRS resource, a CSI-RS resource, or a Channel State Information Interference Measurement Reference Signal (CSI-IM) resource, etc.

[0038] In this embodiment, the network device can send DCI signaling for non-periodic or semi-persistent reference signal resources to the terminal device. Correspondingly, the terminal device can receive the DCI signaling sent by the network device, and triggering signaling is used to instruct the transmission or reception of target signals corresponding to multiple reference signal resources and / or target signals corresponding to multiple sets of reference signal resources.

[0039] Optionally, for uplink reference signal resources, the terminal device can transmit uplink reference signals. In this case, the terminal device receives a trigger signaling message, which is used to instruct the transmission of target signals corresponding to multiple reference signal resources and / or target signals corresponding to multiple sets of reference signal resources. For downlink reference signal resources, the terminal device can receive downlink reference signals. In this case, the terminal device receives a trigger signaling message, which is used to instruct the reception of target signals corresponding to multiple reference signal resources and / or target signals corresponding to multiple sets of reference signal resources.

[0040] Optionally, the DCI signaling received from the network device can be used to instruct the terminal device to transmit target signals corresponding to one or more reference signal resources; alternatively, the DCI signaling received from the network device can be used to instruct the terminal device to transmit target signals corresponding to one or more sets of reference signal resources; alternatively, the DCI signaling received from the network device can be used to instruct the terminal device to transmit target signals corresponding to at least one reference signal resource and at least one set of reference signal resources.

[0041] S102. Adjust the time-domain transmission positions of the target signals corresponding to at least a portion of multiple reference signal resources and / or the time-domain transmission positions of the target signals corresponding to at least a portion of multiple reference signal resource sets by the same number of time units to determine the actual time-domain transmission position of the target signal.

[0042] The time-domain transmission position can be used to indicate the transmission time of the reference signal.

[0043] The time unit can be a time slot, and the number of time units can be the number of time slots.

[0044] In this embodiment, after receiving a trigger signaling message from a network device, the terminal device can determine, based on the trigger signaling message, the time-domain transmission position of the target signal corresponding to at least a portion of the aperiodic or semi-persistent reference signal resources indicated by the DCI signaling and / or the target signal corresponding to at least a portion of the aperiodic or semi-persistent reference signal resource set. Further, the terminal device can adjust the time-domain transmission position of the target signal indicated by the DCI signaling by the same number of time units to determine the actual time-domain transmission position of the target signal.

[0045] Optionally, the terminal device can increase the time-domain transmission position of the target signal indicated by the DCI signaling by the same number of time units, that is, by delaying by the same number of time units, to move the time-domain transmission position of the target signal backward according to the number of time units; alternatively, the terminal device can decrease the time-domain transmission position of the target signal indicated by the DCI signaling by the same number of time units, that is, by advancing by the same number of time units, to move the time-domain transmission position of the target signal forward according to the number of time units.

[0046] Optionally, the terminal determines the actual time-domain transmission location of the target signal based on the adjusted result.

[0047] Optionally, the terminal device can use the adjusted time-domain transmission position as the actual time-domain transmission position of the target signal.

[0048] If the adjusted time-domain transmission position is the time-domain transmission position obtained by increasing the same number of time units, then the time-domain transmission position obtained by moving backward can be used as the actual time-domain transmission position of the target signal; if the adjusted time-domain transmission position is the time-domain transmission position obtained by reducing the same number of time units, then the time-domain transmission position obtained by moving forward can be used as the actual time-domain transmission position of the target signal.

[0049] According to an embodiment of this application, a signal transmission method allows a terminal device to receive a triggering signaling sent by a network device. The triggering signaling instructs the terminal device to transmit or receive target signals corresponding to multiple reference signal resources and / or target signals corresponding to multiple sets of reference signal resources. The method adjusts the time-domain transmission positions of at least some of the target signals corresponding to multiple reference signal resources and / or the time-domain transmission positions of at least some of the target signals corresponding to multiple sets of reference signal resources to the same number of time units to determine the actual time-domain transmission position of the target signal. This eliminates the need to restrict signal transmission to a fixed time-domain transmission position, thus improving the flexibility of the signal transmission process.

[0050] It should be noted that in this application, after receiving the trigger signaling, the time domain transmission position can be adjusted according to the received trigger signaling; alternatively, the adjustment signaling can be obtained and the time domain transmission position can be adjusted according to the adjustment signaling.

[0051] Optionally, before attempting to adjust the time-domain transmission positions of at least a portion of the target signals corresponding to multiple reference signal resources and / or at least a portion of the target signals corresponding to multiple reference signal resource sets to the same number of time units, it can be determined whether there are unusable transmission time units in the time-domain transmission positions of each target signal, and whether to adjust the time-domain transmission positions based on the determination result.

[0052] As one possible implementation, such as Figure 3 As shown, the specific steps include:

[0053] S201. Determine the time-domain transmission location of each target signal according to the trigger signaling.

[0054] Taking SRS resource sets as an example, if the base station sends a trigger signaling to the UE through the SRS Request field in the DCI at the time-domain transmission location, instructing the UE to transmit target signals corresponding to N (N>1) SRS resource sets, the UE can use the formula... Determine the time-domain transmission location. Here, n is the time unit where the DCI is located, k is the transmission time unit offset value configured by the base station for the SRS resource set, and μSRS and μPDCCH are the subcarrier spacing values ​​of the SRS resource set and the PDCCH carrying the DCI trigger signaling, respectively.

[0055] It should be noted that if there are no multiple subcarrier intervals, the UE can determine the transmission time unit of the SRS corresponding to each SRS resource set according to the formula n+k.

[0056] S202. Determine whether there are unusable transmission time units in the time domain transmission location, and determine whether to adjust the time domain transmission location based on the determination result.

[0057] Optionally, when it is determined that there are unusable transmission time units in the time-domain transmission positions of at least some of the target signals, the time-domain transmission positions can be adjusted.

[0058] Optionally, adjustments can be made to determine if there are unusable transmission time units in the time-domain transmission position of the target signal corresponding to the target reference signal resource set and / or in the time-domain transmission position of the target signal corresponding to the target reference signal resource set.

[0059] The following sections explain how to determine whether a transmission time unit is available or unavailable in the time-domain transmission location of a target signal corresponding to a reference signal resource or a set of reference signal resources.

[0060] For a reference signal in the target transmission direction, the available transmission time units of the target signal corresponding to the reference signal resource must satisfy at least one of the following:

[0061] A transmission time unit includes all transmission symbols required in all target transmission directions for the target signal to be transmitted within that transmission time unit; or,

[0062] The transmission time unit includes all transmission symbols required for the transmission of the target signal in all target transmission directions within that transmission time unit, and there is no signal in that transmission time unit that has a higher priority than the target signal corresponding to the reference signal resource and overlaps with the target signal in time; or,

[0063] The transmission time unit is the time unit in the target transmission direction; or,

[0064] The transmission time unit is the target transmission direction time unit, and there is no signal in the transmission time unit that has a higher priority than the target signal corresponding to the reference signal resource and overlaps with the target signal in time.

[0065] For a reference signal in the target transmission direction, the available transmission time units of the target signal corresponding to the reference signal resource set must satisfy at least one of the following:

[0066] A transmission time unit includes all transmission symbols required in all target transmission directions for the target signal to be transmitted within that transmission time unit; or,

[0067] A transmission time unit includes transmission symbols for all target transmission directions required for the transmission of the target signal corresponding to the reference signal resource within that transmission time unit, and there is no signal with a higher priority than the target signal corresponding to the reference signal resource and which overlaps with the target signal in time within that transmission time unit; or,

[0068] A transmission time unit includes all transmission symbols required in all target transmission directions for each target signal corresponding to the reference signal resource set during transmission within that transmission time unit; or,

[0069] A transmission time unit includes all transmission symbols in the target transmission directions required for each target signal corresponding to the reference signal resource set to be transmitted in that transmission time unit, and there is no signal with a higher priority than each target signal corresponding to the reference signal resource set in that transmission time unit; or,

[0070] The transmission time unit is the time unit in the target transmission direction; or,

[0071] The transmission time unit is the target transmission direction time unit, and there is no signal with a higher priority than each target signal corresponding to the reference signal resource set in this time unit.

[0072] For a reference signal in the target transmission direction, the transmission time unit in the time domain transmission location of the target signal corresponding to the reference signal resource is a transmission time unit that is unavailable, including the following:

[0073] If a transmission time unit includes all transmission symbols in the target transmission direction required for the transmission of the target signal corresponding to the reference signal resource in that transmission time unit, then it is a usable transmission time unit; otherwise, it is an unusable transmission time unit.

[0074] If a transmission time unit includes all transmission symbols in the target transmission direction required for the transmission of the target signal corresponding to the reference signal resource in the transmission time unit, and there is no signal in the transmission time unit that has a higher priority than the target signal corresponding to the reference signal resource and overlaps with the target signal in time, then it is a usable transmission time unit; otherwise, it is an unusable transmission time unit.

[0075] If the transmission time unit is the target transmission direction time unit, then it is a usable transmission time unit; otherwise, it is an unusable transmission time unit.

[0076] If the transmission time unit is the target transmission direction time unit, and there is no signal in the time unit that has a higher priority than the target signal corresponding to the reference signal resource and overlaps with the target signal in time, then it is a usable transmission time unit; otherwise, it is an unusable transmission time unit.

[0077] For a reference signal in the target transmission direction, the transmission time unit in the time domain transmission location of the target signal corresponding to the reference signal resource is a transmission time unit that is unavailable, including the following:

[0078] If a transmission time unit includes all transmission symbols in the target transmission direction required for the transmission of the target signal corresponding to the reference signal resource in that transmission time unit, then it is a usable transmission time unit; otherwise, it is an unusable transmission time unit.

[0079] If a transmission time unit includes all transmission symbols in the target transmission direction required for the transmission of the target signal corresponding to the reference signal resource in the transmission time unit, and there is no signal in the transmission time unit that has a higher priority than the target signal corresponding to the reference signal resource and overlaps with the target signal in time, then it is a usable transmission time unit; otherwise, it is an unusable transmission time unit.

[0080] If a transmission time unit includes all the transmission symbols in the target transmission direction required for each target signal corresponding to the reference signal resource set to be transmitted in the transmission time unit, then it is a usable transmission time unit; otherwise, it is an unusable transmission time unit.

[0081] If a transmission time unit includes all transmission symbols in the target transmission direction required for each target signal corresponding to the reference signal resource set to be transmitted in the transmission time unit, and there is no signal in the transmission time unit with a higher priority than any target signal corresponding to the reference signal resource set, then it is a usable transmission time unit; otherwise, it is an unusable transmission time unit.

[0082] If the transmission time unit is the target transmission direction time unit, then it is a usable transmission time unit; otherwise, it is an unusable transmission time unit.

[0083] If a transmission time unit is a target transmission direction time unit, and there is no signal with a higher priority than each target signal corresponding to the reference signal resource set in that time unit, then it is a usable transmission time unit; otherwise, it is an unusable transmission time unit.

[0084] Optionally, when the target transmission direction is uplink, the transmission time unit is specifically the uplink timeslot; when the target transmission direction is downlink, the transmission time unit is specifically the downlink timeslot.

[0085] Taking SRS signals as an example, if the uplink symbols of a transmission time unit include all the uplink symbols required by an SRS resource / SRS resource set, and there is no transmission of a signal with a higher priority than the SRS signal on the uplink symbols, then the transmission time unit is the available time slot of the SRS resource / SRS resource set.

[0086] For example, if an aperiodic SRS resource needs to be transmitted on the last two symbols of a transmission time unit, and the base station does not schedule or configure the transmission of other uplink signals for the last two symbols of an uplink transmission time unit, then that transmission time unit is an available time slot for this aperiodic SRS resource. If an aperiodic SRS resource needs to be transmitted on the last two symbols of a transmission time unit, and the base station schedules the transmission of uplink signals with higher priority for the last two symbols of an uplink transmission time unit, then that transmission time unit is not an available time slot for this aperiodic SRS resource.

[0087] Taking SRS signals as an example, if the uplink symbols included in a transmission time unit cover the uplink symbols required for the transmission of an SRS signal of an SRS resource or SRS resource set, that is, if the transmission time unit includes all transmission symbols in the target transmission direction required for the target signal corresponding to the SRS resource or SRS resource set to be transmitted in the transmission time unit, then this transmission time unit is an available transmission time unit of the SRS resource or SRS resource set; otherwise, the transmission time unit is an unavailable transmission time unit of the SRS resource or SRS resource set.

[0088] For example, if an aperiodic SRS resource needs to be transmitted on the last two symbols of a time slot, if the last two symbols of a transmission time unit are uplink symbols, then that transmission time unit is an available transmission time unit for the aperiodic SRS resource; if a transmission time unit is a downlink transmission time unit, or if the last two symbols of a flexible transmission time unit are downlink symbols, then that transmission time unit is not an available transmission time unit for the aperiodic SRS resource.

[0089] It should be noted that the aforementioned reference signal for the target transmission direction can be either an uplink reference signal or a downlink reference signal.

[0090] In this embodiment of the application, if there is an unavailable transmission time unit in the time domain transmission location, step S202 can be executed; if there is no unavailable transmission time unit in the time domain transmission location, that is, all transmission time units are available, the UE can transmit in each available time unit.

[0091] As one possible implementation, adjustments can be made when it is determined that there are unusable transmission time units in the time-domain transmission location of at least some of the target signals.

[0092] As another possible implementation, adjustments can be made to determine if there are unusable transmission time units in the time-domain transmission position of the target signal corresponding to the target reference signal resource set and / or in the time-domain transmission position of the target signal corresponding to the target reference signal resource set.

[0093] Optionally, when attempting to adjust the time-domain transmission positions of the target signals corresponding to at least a portion of multiple reference signal resources and / or the time-domain transmission positions of the target signals corresponding to at least a portion of multiple reference signal resource sets to the same number of time units, adjustment signaling can be obtained, and the time-domain transmission positions of the target signals corresponding to at least a portion of multiple reference signal resources and / or the time-domain transmission positions of the target signals corresponding to at least a portion of multiple reference signal resource sets can be adjusted to the same number of time units according to the adjustment signaling.

[0094] As one possible implementation, such as Figure 4As shown, the specific steps include:

[0095] S301, Obtain adjustment signaling.

[0096] S302. According to the adjustment signaling, adjust the time-domain transmission positions of the target signals corresponding to at least a portion of multiple reference signal resources and / or the time-domain transmission positions of the target signals corresponding to at least a portion of multiple reference signal resource sets to the same number of time units.

[0097] In this embodiment, the network device can send adjustment signaling to the terminal device to instruct the terminal device to adjust the time-domain transmission position of the target signal corresponding to multiple reference signal resources and / or the time-domain transmission position of the target signal corresponding to multiple sets of reference signal resources. Accordingly, the terminal device can receive the adjustment signaling sent by the network device. Further, after receiving the adjustment signaling, the terminal device adjusts the time-domain transmission positions of at least a portion of the target signals corresponding to multiple reference signal resources and / or at least a portion of the target signals corresponding to multiple sets of reference signal resources by the same number of time units.

[0098] It should be noted that, based on the above embodiments, the time-domain transmission positions of the target signals corresponding to at least a portion of multiple reference signal resources and / or the time-domain transmission positions of the target signals corresponding to at least a portion of multiple reference signal resource sets can be adjusted to the same number of time units through the following possible implementation methods.

[0099] As one possible implementation, the time-domain transmission positions of the target signals corresponding to all multiple reference signal resources and / or the time-domain transmission positions of the target signals corresponding to all multiple sets of reference signal resources can be adjusted to the same number of time units.

[0100] As another possible implementation, the time-domain transmission positions of the target signals corresponding to multiple reference signal resources with unavailable transmission time units and / or the time-domain transmission positions of the target signals corresponding to multiple sets of reference signal resources can be adjusted to the same number of time units.

[0101] As another possible implementation, the time-domain transmission position of the target signal corresponding to the target reference signal resource and / or the time-domain transmission position of the target signal corresponding to the target reference signal resource set can be adjusted to the same number of time units. Here, the target reference signal resource is a reference signal resource that meets the preset conditions among multiple reference signal resources, and the target reference signal resource set is a set of reference signal resources that meets the preset conditions among multiple reference signal resource sets.

[0102] It should be noted that, based on the above embodiments, the number of time units can be determined through the following possible implementation methods.

[0103] One possible approach is to determine the number of time units that need to be adjusted based on the time-domain transmission location of the target signal.

[0104] As another possible implementation, the number of time units can be determined by obtaining the indication information used to indicate the number of time units.

[0105] As another possible implementation, the transmission parameter information of the physical channel carrying the trigger signaling can be obtained, and the number of time units can be determined based on the transmission parameter information. Optionally, the transmission parameter information can be obtained, and the number of time units can be determined by querying the correspondence between the number of time units and the transmission parameter information of the physical channel carrying the trigger signaling.

[0106] As another possible implementation, the number of time units can be determined based on the target signal corresponding to the target reference signal resource and / or the target signal corresponding to the target reference signal resource set.

[0107] For example, the number of time units is the number of time units that makes the actual transmission time unit of the target signal corresponding to the target reference signal resource and / or the target signal corresponding to the target reference signal resource set a usable time unit. Optionally, the number of time units is the minimum number of time units that makes the actual transmission time unit of the target signal corresponding to the target reference signal resource and / or the target signal corresponding to the target reference signal resource set a usable time unit.

[0108] The transmission parameter information may include one or more of the following: the identifier of the serving cell where the physical channel carrying the trigger signaling is located; the identifier of the component carrier (CC); the identifier of the bandwidth part (BWP); the identifier of the control resource set (CORESET); the identifier of the common search space; and the identifier of the corresponding transmission reception point (TRP).

[0109] It should be noted that after determining the number of time units, if there exists a number of time units that makes all actual time-domain transmission locations available as transmission time units, then the adjustment should be made based on that number of transmission time units; if there are at least two numbers of time units that make all actual time-domain transmission locations available as transmission time units, then the minimum number of time units can be selected, and the adjustment should be made based on that minimum number of time units.

[0110] Optionally, the adjusted number of time units is the minimum number of time units required to ensure that all SRS resources and / or the SRS corresponding to the SRS resource set are transmitted within available time units.

[0111] For example, assuming N=2, DCI triggers SRS resource set 1 and SRS resource set 2, and the UE determines that their transmission time units are both unavailable time units, and the transmission time unit of SRS resource set 1 is m, and the transmission time unit of SRS resource set 2 is m+2, time units m and m+2 are both downlink time units, i.e. unavailable time units, while time units m+1 and m+3 are uplink time units, and are available time units of SRS resource set 1 and SRS resource set 2 respectively. Then, delaying SRS resource set 1 and SRS resource set 2 by 1 time unit will make them available so that they can both transmit in the available time units, and the number of delayed time units is 1.

[0112] For example, suppose N=2, DCI triggers SRS resource set 1 and SRS resource set 2, and the UE determines that their transmission time units are both unavailable time units. The transmission time unit of SRS resource set 1 is time unit m, and the transmission time unit of SRS resource set 2 is m+2. Time units m and m+2 are downlink time units, i.e., unavailable time units. Time units m+1 and m+3 are available units of SRS resource set 1. m+3 and m+4 are not available time units of SRS resource set 2. m+5 is an available time unit of SRS resource set 2. Then, delaying SRS resource set 1 and SRS resource set 2 by 3 time units will allow them to transmit in available time units. Therefore, the number of delayed time units is 3.

[0113] It should be noted that when adjusting the time-domain transmission positions of target signals corresponding to at least a portion of multiple reference signal resources and / or the time-domain transmission positions of target signals corresponding to at least a portion of multiple reference signal resource sets to the same number of time units, configuration information can be obtained, and the time-domain transmission positions of target signals corresponding to target reference signal resources that meet preset conditions and / or the target reference signal resource sets can be determined based on the configuration information. Alternatively, the time-domain transmission positions of each unavailable transmission time unit and the difference between them and the next available transmission time unit can be obtained, and the target reference signal resources or target reference signal resource sets that meet preset conditions can be determined based on the difference.

[0114] Optionally, configuration information can be obtained, and the time-domain transmission location of the target signal corresponding to the target reference signal resource and / or the set of target reference signal resources can be determined based on the configuration information.

[0115] As one possible implementation, such as Figure 5 As shown, based on the above embodiments, the specific steps include:

[0116] S401. Obtain the time-domain transmission location of the target signal corresponding to multiple reference signal resources and / or the configuration information of multiple reference signal resource sets.

[0117] S402. Determine the time-domain transmission location of the target signal and / or the set of target reference signal resources corresponding to the target reference signal resources based on the configuration information.

[0118] The configuration information includes one or more of the following: the offset between the time-domain transmission location of the triggering signaling and the time-domain transmission location of the target signal; the identifier of the reference signal resource or reference signal resource set; the identifier of the serving cell corresponding to the reference signal resource or reference signal resource set; the priority of the reference signal resource or reference signal resource set; and the usage type of the reference signal resource or reference signal resource set.

[0119] Optionally, if the configuration information includes the offset between the time-domain transmission position of the triggering signal and the time-domain transmission position of the target signal, the offset can be obtained through one of the following methods. Further, the time-domain transmission position of the target signal corresponding to the target reference signal resource and / or the set of target reference signal resources can be determined based on the offset.

[0120] One possible implementation is to receive offset indication information sent by a network device and determine the offset corresponding to a reference signal resource or a set of reference signal resources based on the offset indication information.

[0121] As another possible implementation, the offset is the default configuration value.

[0122] Taking the SRS signal as an example, the offset is the offset between the time unit of transmitting the DCI and the time unit of the SRS corresponding to the SRS resource or SRS resource set that it triggers.

[0123] If the base station indicates an offset for an SRS resource or set of SRS resources, meaning the terminal device has received offset indication information sent by the network device, the UE can determine the offset based on the received offset indication information sent by the base station. For example, the UE can use the offset of the SRS resource or set of SRS resources triggered by the DCI with the largest offset value as the offset based on the received offset indication information sent by the base station; or, for another example, the UE can use the offset of the SRS resource or set of SRS resources triggered by the DCI with the smallest offset value as the offset based on the received offset indication information sent by the base station.

[0124] If the base station does not indicate an offset for an SRS resource or SRS resource set, the UE can use the default configuration value as the offset for that SRS resource or SRS resource set. The default configuration value can be preset according to actual conditions; for example, it can be set to 0.

[0125] Optionally, if the configuration information includes an identifier of a reference signal resource or a set of reference signal resources, the time-domain transmission location of the target signal corresponding to the target reference signal resource and / or the set of target reference signal resources can be determined based on the identifier.

[0126] Taking SRS signals as an example, the UE can use the identifier of the reference signal resource or reference signal resource set to determine the SRS resource or SRS resource set with the largest identifier triggered by the DCI as the time-domain transmission location and / or target reference signal resource set corresponding to the target reference signal resource; or it can use the identifier of the reference signal resource or reference signal resource set to determine the SRS resource or SRS resource set with the smallest identifier triggered by the DCI as the time-domain transmission location and / or target reference signal resource set corresponding to the target reference signal resource.

[0127] Optionally, if the configuration information includes the identifier or CC identifier of the serving cell corresponding to the reference signal resource or the set of reference signal resources, the time-domain transmission location of the target signal corresponding to the target reference signal resource and / or the set of target reference signal resources can be determined based on the identifier or CC identifier of the serving cell.

[0128] Taking SRS signals as an example, the UE can use the identifier of the serving cell corresponding to the reference signal resource or reference signal resource set to select the SRS resource triggered by DCI or the SRS resource set with the largest serving cell identifier as the time-domain transmission location and / or target reference signal resource set corresponding to the target reference signal resource. Alternatively, the UE can use the identifier of the serving cell corresponding to the reference signal resource or reference signal resource set to select the SRS resource triggered by DCI or the SRS resource set with the smallest serving cell identifier as the time-domain transmission location and / or target reference signal resource set corresponding to the target reference signal resource.

[0129] Optionally, if the configuration information includes the identifier of the reference signal resource or reference signal resource set and the purpose type of the reference signal resource or reference signal resource set, but does not include the priority of the reference signal resource or reference signal resource set, the priority of the reference signal resource or reference signal resource set can be obtained in the following ways.

[0130] For reference signal resources, the priority of the reference signal resources can be determined based on their usage type and / or their identifier.

[0131] For a set of reference signal resources, the priority of the set can be determined based on its usage type and the identifier of the reference signal resources within it.

[0132] Optionally, if the configuration information includes the usage type of the reference signal resource or the reference signal resource set, the time-domain transmission location of the target signal corresponding to the target reference signal resource and / or the target reference signal resource set can be determined according to the usage type.

[0133] Taking SRS signals as an example, the UE can use the SRS resources or SRS resource sets triggered by DCI with a specific usage type as the time-domain transmission location of the target signal corresponding to the target reference signal resource and / or the target reference signal resource set, based on the usage type of the reference signal resource or the reference signal resource set.

[0134] It should be noted that if the configuration information includes the aforementioned multiple pieces of information, then the time-domain transmission location of the target signal corresponding to the target reference signal resource and / or the set of target reference signal resources can be further defined by combining the multiple pieces of information.

[0135] Taking SRS signals as an example, if the configuration information includes the purpose type and offset of the reference signal resource or reference signal resource set, then the SRS resource or SRS resource set with the smallest offset among the SRS resources or SRS resource sets with a specific purpose type triggered by DCI can be used as the time domain transmission position of the target signal corresponding to the target reference signal resource and / or the target reference signal resource set.

[0136] Optionally, the time-domain transmission position of each unavailable transmission time unit and the difference between its corresponding next available transmission time unit can be obtained, and the target reference signal resource or target reference signal resource set can be determined based on the difference.

[0137] As one possible implementation, such as Figure 6 As shown, based on the above embodiments, the specific steps include:

[0138] S501. Obtain the time-domain transmission position of each unavailable transmission time unit and the next available transmission time unit corresponding to each time-domain transmission position.

[0139] S502. Obtain the time-domain transmission position of each unavailable transmission time unit and the difference between its corresponding next available transmission time unit.

[0140] S503. Determine the target reference signal resource or the target reference signal resource set based on the difference.

[0141] Taking SRS signals as an example, optionally, the SRS resources that are unavailable in all transmission time units or the SRS resource set with the smallest difference between the first available time unit after the transmission time unit and the transmission time unit can be used as the time domain transmission position of the target signal corresponding to the target reference signal resource and / or the target reference signal resource set.

[0142] It should be noted that, taking SRS signals as an example, if there are still unavailable time units in the actual time domain transmission location after adjusting the time domain transmission location of an SRS resource or SRS resource set, the UE may not perform (or discard) the SRS transmission of the SRS resource or SRS resource set; otherwise, the UE may perform the SRS transmission of the SRS resource or SRS resource set.

[0143] If, after adjusting the time-domain transmission location of an SRS resource or SRS resource set, there are still unavailable time units in the resulting actual time-domain transmission location, and these unavailable time units include available and unavailable symbols, then the UE will transmit the SRS of the SRS resource or SRS resource set on the available symbols and will not transmit the SRS of the SRS resource or SRS resource set on the unavailable symbols. Conversely, the UE can transmit the SRS of the SRS resource / SRS resource set in the available time slots corresponding to each SRS resource / SRS resource set.

[0144] In summary, according to the signal transmission method of the present application embodiment, the terminal device can receive a trigger signaling sent by the network device. The trigger signaling is used to instruct the terminal device to transmit or receive target signals corresponding to multiple reference signal resources and / or target signals corresponding to multiple sets of reference signal resources. The time-domain transmission positions of at least some of the target signals corresponding to multiple reference signal resources and / or at least some of the target signals corresponding to multiple sets of reference signal resources are adjusted to the same number of time units to determine the actual time-domain transmission position of the target signal. This eliminates the need to restrict signal transmission to a fixed time-domain transmission position, thus improving the flexibility of the signal transmission process.

[0145] Figure 7 This is a schematic diagram according to the sixth embodiment of this application. (See diagram below.) Figure 7 As shown, taking a network device as the executing entity, the signal transmission method proposed in the embodiments of this application will be explained and described, specifically including the following steps:

[0146] S601. Send a trigger signaling to the terminal device, the trigger signaling instructing the terminal device to transmit target signals corresponding to multiple reference signal resources and / or target signals corresponding to multiple sets of reference signal resources; wherein, the time-domain transmission positions of at least some of the target signals corresponding to multiple reference signal resources and / or the target signals corresponding to at least some of the target signals corresponding to multiple sets of reference signal resources differ from their actual time-domain transmission positions by the same number of time units.

[0147] Optionally, for uplink reference signal resources, the base station can receive uplink reference signals; for downlink reference signal resources, the base station can transmit downlink reference signals.

[0148] In this embodiment of the application, the network device may send DCI signaling of non-periodic or semi-persistent reference signal resources to the terminal device to instruct the terminal device to perform time-domain transmission of target signals corresponding to multiple reference signal resources and / or transmission of target signals corresponding to multiple sets of reference signal resources.

[0149] According to an embodiment of this application, a signal transmission method allows a terminal device to receive a triggering signaling sent by a network device. The triggering signaling instructs the terminal device to transmit or receive target signals corresponding to multiple reference signal resources and / or target signals corresponding to multiple sets of reference signal resources. The method adjusts the time-domain transmission positions of at least some of the target signals corresponding to multiple reference signal resources and / or the time-domain transmission positions of at least some of the target signals corresponding to multiple sets of reference signal resources to the same number of time units to determine the actual time-domain transmission position of the target signal. This eliminates the need to restrict signal transmission to a fixed time-domain transmission position, thus improving the flexibility of the signal transmission process.

[0150] It should be noted that, in this application, after sending the trigger signaling, the network device can determine the time-domain transmission location of the trigger signaling and the actual time-domain transmission location of the target signal based on the number of time units.

[0151] Optionally, the network device can determine the time-domain transmission position of the trigger signaling according to the number of time units, and send the trigger signaling to the terminal device according to the determined time-domain transmission position to instruct the terminal device to transmit the time-domain transmission position of the target signal corresponding to multiple reference signal resources and / or the target signal corresponding to the multiple reference signal resource sets.

[0152] Optionally, the network device can determine the time-domain transmission position of the target signal corresponding to at least a portion of multiple reference signal resources and / or the actual time-domain transmission position of the target signal corresponding to at least a portion of multiple reference signal resource sets based on the number of time units, wherein the actual transmission time-domain position is the adjusted time-domain transmission position.

[0153] It should be noted that, in this application, the network device can send adjustment signaling to the terminal device, wherein the adjustment signaling instructs the terminal device to adjust the time-domain transmission position of the target signal corresponding to multiple reference signal resources and / or the target signal corresponding to multiple sets of reference signal resources. Accordingly, the terminal device can acquire the adjustment signaling and adjust the time-domain transmission position of at least a portion of the target signals corresponding to multiple reference signal resources and / or at least a portion of the target signals corresponding to multiple sets of reference signal resources by the same number of time units according to the adjustment signaling.

[0154] Furthermore, in this application, the time-domain transmission position of the target signal corresponding to at least a portion of the multiple reference signal resources and / or the target signal corresponding to at least a portion of the multiple reference signal resource sets includes: the time-domain transmission position of the target signal corresponding to all the multiple reference signal resources and / or the target signal corresponding to all the multiple reference signal resource sets, the time-domain transmission position of the target signal corresponding to the multiple reference signal resources with unusable transmission time units and / or the target signal corresponding to the multiple reference signal resource sets, and the time-domain transmission position of the target signal corresponding to the target reference signal resource and / or the target signal corresponding to the target reference signal resource set.

[0155] It should be noted that, in this application, optionally, the network device can determine the number of transmission time units based on whether there are unavailable transmission time units in the time-domain transmission location; optionally, the network device can determine the number of time units based on the time-domain transmission location of the target signal; optionally, the network device can send indication information to the terminal device to indicate the number of time units; optionally, there is a correspondence between the number of time units and the transmission parameter information of the physical channel carrying the trigger signaling; optionally, the number of time units can be determined based on the target signal corresponding to the target reference signal resource and / or the target signal corresponding to the target reference signal resource set.

[0156] The following sections explain how to determine whether a transmission time unit is available or unavailable in the time-domain transmission location of a target signal corresponding to a reference signal resource or a set of reference signal resources.

[0157] For a reference signal in the target transmission direction, the available transmission time units of the target signal corresponding to the reference signal resource must satisfy at least one of the following:

[0158] A transmission time unit includes all transmission symbols required in all target transmission directions for the target signal to be transmitted within that transmission time unit; or,

[0159] The transmission time unit includes all transmission symbols required for the transmission of the target signal in all target transmission directions within that transmission time unit, and there is no signal in that transmission time unit that has a higher priority than the target signal corresponding to the reference signal resource and overlaps with the target signal in time; or,

[0160] The transmission time unit is the time unit in the target transmission direction; or,

[0161] The transmission time unit is the target transmission direction time unit, and there is no signal in the transmission time unit that has a higher priority than the target signal corresponding to the reference signal resource and overlaps with the target signal in time.

[0162] For a reference signal in the target transmission direction, the available transmission time units of the target signal corresponding to the reference signal resource set must satisfy at least one of the following:

[0164] A transmission time unit includes transmission symbols for all target transmission directions required for the transmission of the target signal corresponding to the reference signal resource within that transmission time unit, and there is no signal with a higher priority than the target signal corresponding to the reference signal resource and which overlaps with the target signal in time within that transmission time unit; or,

[0167] The transmission time unit is the time unit in the target transmission direction; or,

[0168] The transmission time unit is the target transmission direction time unit, and there is no signal with a higher priority than each target signal corresponding to the reference signal resource set in this time unit.

[0169] For a reference signal in the target transmission direction, the transmission time unit in the time domain transmission location of the target signal corresponding to the reference signal resource is a transmission time unit that is unavailable, including the following:

[0170] If a transmission time unit includes all transmission symbols in the target transmission direction required for the transmission of the target signal corresponding to the reference signal resource in that transmission time unit, then it is a usable transmission time unit; otherwise, it is an unusable transmission time unit.

[0171] If a transmission time unit includes all transmission symbols in the target transmission direction required for the transmission of the target signal corresponding to the reference signal resource in the transmission time unit, and there is no signal in the transmission time unit that has a higher priority than the target signal corresponding to the reference signal resource and overlaps with the target signal in time, then it is a usable transmission time unit; otherwise, it is an unusable transmission time unit.

[0172] If the transmission time unit is the target transmission direction time unit, then it is a usable transmission time unit; otherwise, it is an unusable transmission time unit.

[0173] If the transmission time unit is the target transmission direction time unit, and there is no signal in the time unit that has a higher priority than the target signal corresponding to the reference signal resource and overlaps with the target signal in time, then it is a usable transmission time unit; otherwise, it is an unusable transmission time unit.

[0174] For a reference signal in the target transmission direction, the transmission time unit in the time domain transmission location of the target signal corresponding to the reference signal resource is a transmission time unit that is unavailable, including the following:

[0175] If a transmission time unit includes all transmission symbols in the target transmission direction required for the transmission of the target signal corresponding to the reference signal resource in that transmission time unit, then it is a usable transmission time unit; otherwise, it is an unusable transmission time unit.

[0176] If a transmission time unit includes all transmission symbols in the target transmission direction required for the transmission of the target signal corresponding to the reference signal resource in the transmission time unit, and there is no signal in the transmission time unit that has a higher priority than the target signal corresponding to the reference signal resource and overlaps with the target signal in time, then it is a usable transmission time unit; otherwise, it is an unusable transmission time unit.

[0177] If a transmission time unit includes all the transmission symbols in the target transmission direction required for each target signal corresponding to the reference signal resource set to be transmitted in the transmission time unit, then it is a usable transmission time unit; otherwise, it is an unusable transmission time unit.

[0178] If a transmission time unit includes all transmission symbols in the target transmission direction required for each target signal corresponding to the reference signal resource set to be transmitted in the transmission time unit, and there is no signal in the transmission time unit with a higher priority than any target signal corresponding to the reference signal resource set, then it is a usable transmission time unit; otherwise, it is an unusable transmission time unit.

[0179] If the transmission time unit is the target transmission direction time unit, then it is a usable transmission time unit; otherwise, it is an unusable transmission time unit.

[0180] If a transmission time unit is a target transmission direction time unit, and there is no signal with a higher priority than each target signal corresponding to the reference signal resource set in that time unit, then it is a usable transmission time unit; otherwise, it is an unusable transmission time unit.

[0181] It should be noted that the aforementioned reference signal for the target transmission direction can be either an uplink reference signal or a downlink reference signal.

[0182] It should be noted that, in this application, the number of time units is the minimum number of time units required to ensure that the transmission time units in all actual time-domain transmission locations are usable transmission time units.

[0183] It should be noted that the target reference signal resource configuration information is the time-domain transmission position of the target signal corresponding to the reference signal resource that meets the preset conditions and / or the target reference signal resource set is the time-domain transmission position of the target signal and / or the reference signal resource set corresponding to the reference signal resource whose configuration information meets the preset conditions.

[0184] The configuration information includes one or more of the following: the offset between the time-domain transmission position of the triggering signaling and the time-domain transmission position of the target signal; the identifier of the reference signal resource or reference signal resource set; the identifier of the serving cell corresponding to the reference signal resource or reference signal resource set; the priority of the reference signal resource or reference signal resource set; and the usage type of the reference signal resource or reference signal resource set. Optionally, the network device can send offset indication information to the terminal device, wherein the offset indication information is used to determine the offset corresponding to the reference signal resource or reference signal resource set. Accordingly, the terminal device can determine the time-domain transmission position of the target signal corresponding to the target reference signal resource and / or the target reference signal resource set based on the offset.

[0185] Optionally, the network device may send an identifier of a reference signal resource or a set of reference signal resources to the terminal device. Accordingly, the terminal device can determine the time-domain transmission location of the target signal corresponding to the target reference signal resource and / or the set of target reference signal resources based on the identifier.

[0186] Optionally, the terminal device can determine the time-domain transmission location of the target signal and / or the set of target reference signal resources corresponding to the target reference signal resources based on the identifier of the serving cell or the CC identifier.

[0187] Optionally, for a reference signal resource, the terminal device can determine the priority of the reference signal resource based on its usage type and / or its identifier; for a set of reference signal resources, the terminal device can determine the priority of the set of reference signal resources based on its usage type and the identifier of the reference signal resources in the set.

[0188] Optionally, the terminal device may determine the time-domain transmission location of the target signal and / or the set of target reference signal resources corresponding to the target reference signal resources, based on the type of application.

[0189] Optionally, the network device can determine all time-domain transmission positions for each unavailable transmission time unit and the difference between each time-domain transmission position and the next available transmission time unit thereafter. The time-domain transmission position of the target signal corresponding to the target reference signal resource and / or the set of target reference signal resources is the time-domain transmission position of the target signal and / or the set of reference signal resources whose differences satisfy certain conditions. Accordingly, taking an SRS signal as an example, the terminal device can use the SRS resource or the set of SRS resources with the smallest difference between the first available time unit and the transmission time unit among all unavailable SRS resources for each transmission time unit as the time-domain transmission position of the target signal corresponding to the target reference signal resource and / or the set of target reference signal resources.

[0190] In summary, according to the signal transmission method of the present application embodiment, the terminal device can receive a trigger signaling sent by the network device. The trigger signaling is used to instruct the terminal device to transmit or receive target signals corresponding to multiple reference signal resources and / or target signals corresponding to multiple sets of reference signal resources. The time-domain transmission positions of at least some of the target signals corresponding to multiple reference signal resources and / or at least some of the target signals corresponding to multiple sets of reference signal resources are adjusted to the same number of time units to determine the actual time-domain transmission position of the target signal. This eliminates the need to restrict signal transmission to a fixed time-domain transmission position, thus improving the flexibility of the signal transmission process.

[0191] It should be noted that the base station involved in the embodiments of this application may include multiple cells providing services to terminals. Depending on the specific application, the base station may also be called an access point, or a device in the access network that communicates with the wireless terminal device through one or more sectors on the air interface, or other names. The base station can be used to exchange received air frames with Internet Protocol (IP) packets, and act as a router between the wireless terminal device and the rest of the access network, wherein the rest of the access network may include an Internet Protocol (IP) communication network. The network device can also coordinate the attribute management of the air interface. For example, the base station involved in the embodiments of this application can be a network device (Base Transceiver Station, BTS) in Global System for Mobile communications (GSM) or Code Division Multiple Access (CDMA), or a network device (NodeB) in Wide-band Code Division Multiple Access (WCDMA), or an evolved network device (eNB or e-NodeB) in a long term evolution (LTE) system, a 5G base station (gNB) in a next generation system, or a Home evolved Node B (HeNB), relay node, femto, pico, etc., and is not limited in the embodiments of this application.

[0192] Base stations and terminal devices can each use one or more antennas for multiple-input multiple-output (MIMO) transmission. MIMO transmission can be single-user MIMO (SU-MIMO) or multiple-user MIMO (MU-MIMO). Depending on the configuration and number of antenna combinations, MIMO transmission can be 2D-MIMO, 3D-MIMO, FD-MIMO, or massive-MIMO, and can also be diversity transmission, precoding transmission, or beamforming transmission, etc.

[0208] If it is determined that there is an unusable transmission time unit in the time domain transmission position of the target signal corresponding to the target reference signal resource and / or the target reference signal resource set, the time domain transmission position is adjusted. The target reference signal resource is a reference signal resource that meets a preset condition among the plurality of reference signal resources, and the target reference signal resource set is a set of reference signal resources that meets the preset condition among the plurality of reference signal resource sets.
