Description

Technical Field

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

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 or activated. 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 signaling indicating the timing relationship between the trigger and the sending of the reference signal by the base station.

Since the configuration of Radio Resource Control (RRC) signaling is semi-static, configuring the trigger offset value of the reference signal through RRC signaling makes the triggering of the reference signal inflexible. Also, in a Time Division Duplex (TDD) mode, if the Time slot n + n_offsetFor downlink/uplink time slot, the time slot n + n_offsetThe transmission of the SRS uplink/downlink reference signal cannot be performed. In order to avoid that the reference signal cannot be transmitted, the base station needs to send Downlink Control Information (DCI) at a limited time domain position, thereby reducing the flexibility of triggering the reference signal transmission through the DCI.

Detailed Description

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-continuous signals) can be transmitted only after being triggered (trigger) or activated (active). 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 a Reference Signal as a Sounding Reference Signal (SRS) as an example, in a New Radio (NR) system, a base station configures, for a terminal (User Equipment, UE), an aperiodic SRS (or Channel State Information-Reference Signal (CSI-RS)) resource set and an aperiodic SRS (/ CSI-RS) resource through RRC signaling, and triggers transmission of the aperiodic SRS (/ CSI-RS) resource through an SRS request (request) field (or a Channel State Information (CSI) report (reporting) field) in the DCI signaling. When configuring the aperiodic SRS (/ CSI-RS) resource set by RRC, an RRC signaling slot offset value (slotOffset) (or aperiodic triggering offset value (aperiodicTriggeringOffset)) is used to configure a triggering offset value of an 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) in DCI in a slot (slot) n, signals corresponding to all SRS (/ CSI-RS) resources in the SRS (/ CSI-RS) resource set are transmitted in the slot X, and a calculation formula of X is as follows:

wherein, X is the time domain transmission position, k is the trigger time slot offset value (abbreviated as "time slot offset value") corresponding to the slotOffset (/ aperiod triggergergerging offset), and μ_SRSIs the subcarrier spacing value, μ, of the triggered SRS_PDCCHIs the subcarrier spacing value of the PDCCH carrying the trigger command (i.e., the DCI).

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. In addition, in a Time Division Duplex (TDD) mode, if the 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.

Table 1 shows the position relationship between the trigger timeslot of the PDCCH for triggering SRS and the SRS transmission timeslot under different SRS trigger timeslot offset values in the configuration mode that every five timeslots of the uplink and downlink timeslots are DDFUU, where D denotes a downlink timeslot, U denotes an uplink timeslot, and F denotes a flexible timeslot having both uplink and downlink timeslots. As can be seen from table 1, when the trigger slot offset value is 1, the PDCCH for triggering the aperiodic SRS can be transmitted only in the second downlink slot or the flexible slot.

TABLE 1 positional relationship between trigger slots and transmission slots

slot offset	D	D	F	U	U
						0			PDCCH SRS
1			PDCCH	SRS
						1		PDCCH	SRS
2	PDCCH		SRS
						2		PDCCH		SRS
2			PDCCH		SRS
						3	PDCCH			SRS
3		PDCCH			SRS
						4	PDCCH				SRS

In the prior art, the time slot offset value of the SRS is irrelevant to the parameters of the PDCCH triggering the SRS. No matter which PDCCH is used by the base station to trigger the SRS corresponding to one aperiodic SRS resource, the time slot offset value corresponding to the SRS is the same.

The triggering mode of the non-periodic SRS resource of the NR system and the transmission timing regulation of the non-periodic SRS resource limit the time domain position of DCI (Downlink control information) which triggers the non-periodic SRS resource and the triggering and the transmission of the non-periodic SRS resource are not flexible enough.

Fig. 1 is a schematic diagram of a signal transmission method provided in an embodiment of the present application, and as shown in fig. 1, an implementation subject of the signal transmission method provided in the embodiment of the present application may be a terminal, and the method includes:

step 101, detecting downlink control information DCI triggering first signal transmission.

Specifically, the network device related to the embodiment of the present application may be a base station or a core network element. First, a base station transmits PDCCH configuration information to a UE, where the configuration information includes configuration of parameters of a PDCCH.

The UE detects the DCI according to the PDCCH configuration information, and if a certain DCI is detected to comprise a first signal (for example, the first signal is SRS; and for another example, the first signal is CSI-RS), the signaling is triggered.

The first Signal in the embodiment of the present application may be an aperiodic uplink Signal (e.g., SRS), an aperiodic downlink Signal (e.g., CSI-RS, CSI-IM-RS, etc.), a semi-persistent uplink Signal or a semi-persistent downlink Signal, and the like.

And 102, determining a time-frequency parameter of a Physical Downlink Control Channel (PDCCH) corresponding to the DCI or the type of the DCI.

Specifically, after detecting the DCI triggering the first signal transmission, the UE may determine the time-frequency parameter of the PDCCH corresponding to the DCI or the type of the DCI.

The time-frequency parameter may be Bandwidth Part (BWP) identifier information/BWP group identifier information of the PDCCH, Component Carrier (CC) identifier information/CC group identifier information of the PDCCH, identifier information of a control resource set (CORESET) where the PDCCH is located/identifier information of the CORESET group, identifier information of a search space (searchSpace) corresponding to the PDCCH/identifier information of the search space group, identifier information of a PDCCH candidate (candidate) corresponding to the PDCCH/identifier information of the PDCCH candidate group, aggregation level/aggregation level group corresponding to the PDCCH, number of symbols corresponding to the PDCCH, and the like.

Step 103, determining a time domain transmission position for transmitting the first signal based on the time frequency parameter or the DCI type.

Specifically, after determining the time-frequency parameter of the PDCCH or the type of the DCI, the terminal determines a time-domain transmission location for transmitting the first signal based on the time-frequency parameter or the type of the DCI.

For example, the association relationship between the time-frequency parameter and the time-domain transmission position may be configured or preconfigured by the base station, and after determining the time-frequency parameter, the terminal determines the time-domain transmission position directly according to the association relationship between the time-frequency parameter and the time-domain transmission position.

For another example, the time unit offset value may be determined according to the time-frequency parameter, and then the time domain transmission position for transmitting the first signal may be determined according to the time unit offset value.

The time domain transmission position may be a time unit for transmitting the first signal, and the time unit may be a subframe or a slot. The time unit offset value may be a subframe offset value or a slot offset value.

And 104, sending or receiving the first signal at the time domain transmission position.

Specifically, the terminal transmits or receives the first signal at the time domain transmission position after determining the time domain transmission position.

The base station receives or transmits the first signal at the time domain transmission location.

The embodiment of the application provides a signal transmission method, which detects DCI according to PDCCH configuration information, and determines a time domain transmission position for transmitting a first signal according to a time frequency parameter of the PDCCH for transmitting the DCI or the type of the DCI when a certain DCI is detected to comprise a first signal trigger signaling, so that the flexibility of triggering the transmission of the first signal through the DCI is improved.

Based on any of the above embodiments, the time domain transmission location is a time unit for transmitting the first signal.

Specifically, in the embodiment of the present application, the time domain transmission position refers to a time unit for transmitting the first signal, and the time unit may be a subframe or a slot.

The embodiment of the present application provides a signal transmission method, where a time domain transmission position refers to a time unit for transmitting a first signal, and the time unit may be a subframe or a time slot, so as to further improve flexibility of triggering transmission of the first signal through DCI.

Based on any of the above embodiments, determining a time domain transmission position for transmitting the first signal based on the time-frequency parameter specifically includes:

determining a time unit offset value based on the time-frequency parameter;

Specifically, in the embodiment of the present application, the specific steps of determining the time domain transmission position for transmitting the first signal based on the time-frequency parameter are as follows:

first, a time cell offset value is determined based on the time-frequency parameters.

For example, the time cell offset value may be determined directly from the time-frequency parameters. First, the association relationship between the time-frequency parameter and the time unit offset value is configured or preconfigured by the base station. Then, after the terminal determines the time-frequency parameter, the terminal determines the time unit deviation value according to the incidence relation between the time-frequency parameter and the time unit deviation value.

For another example, the terminal may also determine a time cell offset value based on the time-frequency parameter and the first signal resource.

For another example, the terminal can also determine a time cell offset value based on the time-frequency parameter and the first set of signal resources.

For another example, the terminal may further determine the time unit offset value based on the time-frequency parameter, the first signal resource, and the trigger status corresponding to the DCI.

For another example, the terminal may further determine the time unit offset value based on the time-frequency parameter, the first set of signal resources, and the trigger status corresponding to the DCI.

Then, a time domain transmission position for transmitting the first signal is determined according to the time unit offset value. The specific manner of determining the time domain transmission position for transmitting the first signal according to the time unit offset value may be the same as that of the existing scheme, and is not described herein again.

The embodiment of the application provides a signal transmission method, which determines a time unit deviation value based on a time frequency parameter, and then determines a time domain transmission position for transmitting a first signal based on the time unit deviation value, so that the flexibility of triggering the first signal transmission through DCI is further improved.

Based on any of the above embodiments, the determining a time domain transmission position for transmitting the first signal based on the time-frequency parameter specifically includes:

first, a first time unit offset value is determined based on a time-frequency parameter.

A time domain transmission location for transmitting the first signal is then determined based on the first time unit offset value and a second time unit offset value, the second time unit offset value being configured or preconfigured by the network device.

For example, the time cell offset value comprises a plurality of portions, and the time-frequency parameter is associated with only a portion thereof (the first time cell offset value).

That is, the UE can only determine a part of the information of the time unit offset value according to the time-frequency parameter, and another part of the information (the second time unit offset value) needs to be obtained through other signaling or parameters, or another part of the information is preconfigured.

The UE can determine the time domain transmission location of the first signal only from all information of the time unit offset values (the first time unit offset value and the second time unit offset value).

The embodiment of the application provides a signal transmission method, which determines a first time unit deviation value according to a time frequency parameter, and then determines a time domain transmission position for transmitting a first signal according to the first time unit deviation value and a second time unit deviation value, so that the flexibility of triggering the first signal transmission through DCI is further improved.

Based on any of the above embodiments, the determining a time unit offset value based on the time-frequency parameter specifically includes:

determining the parity of the value of the time-frequency parameter;

Specifically, in the embodiment of the present application, the specific steps of determining the time unit deviation value based on the time-frequency parameter are as follows:

firstly, the parity of the value of the time-frequency parameter is determined.

And then, determining the time unit deviation value according to the parity of the value of the time frequency parameter and the third time unit deviation value. The third time unit offset value is a time unit offset value indicated by the network device.

For example, the calculation formula of the time unit offset value is as follows:

wherein, B is a time unit deviation value, A is a third time unit deviation value, and m and n are preset constants.

The embodiment of the application provides a signal transmission method, which determines a time unit deviation value according to the parity of the value of the time-frequency parameter and the third time unit deviation value, and further improves the flexibility of triggering the first signal transmission through DCI.

or, specifically, includes:

Specifically, in the embodiment of the present application, a specific manner for determining the time unit offset value based on the time-frequency parameter may adopt any one of the following manners:

1. a time cell offset value is determined based on the time-frequency parameter and the first signal resource.

For example, the base station may configure or pre-configure an association relationship between the time frequency parameter, the first signal resource, and the time unit offset value, and after determining the time frequency parameter and the first signal resource, the terminal determines the time unit offset value according to the association relationship between the time frequency parameter, the first signal resource, and the time unit offset value.

When the base station configures the association relationship:

for a given time-frequency parameter, a time unit offset value corresponding to the first signal resource may be configured for each first signal resource, and the time unit offset values corresponding to different first signal resources may be the same or different. Note that for a given time-frequency parameter, the base station may configure a slot offset value for a portion of the first signal resources and not configure a slot offset value for a portion of the first signal resources.

It is also possible to configure the same time unit offset value for all first signal resources for a given time-frequency parameter.

In addition, the network device may also configure a time unit offset value for the time-frequency parameter, which is not described herein again.

For example, for the first signal resource, a time unit offset value corresponding to each value of the time-frequency parameter is configured, and time unit offset values corresponding to different values of the time-frequency parameter may be the same or different. Note that for a given first signal resource, the base station may configure a slot offset value for some values of the time-frequency parameter and not configure a slot offset value for other values of the time-frequency parameter.

2. A time cell offset value is determined based on the time-frequency parameter and the first set of signal resources.

For example, the association relationship between the time frequency parameter, the first signal resource set and the time unit offset value may be configured or preconfigured by the base station, and after determining the time frequency parameter and the first signal resource set, the terminal determines the time unit offset value according to the association relationship between the time frequency parameter, the first signal resource set and the time unit offset value.

When the base station configures the association relationship:

For a given time-frequency parameter, time unit offset values corresponding to the first signal resource set may be configured for each first signal resource set, the time unit offset values corresponding to different first signal resource sets may be the same or different, and the time unit offset values corresponding to all first signal resources in the same first signal resource set are the same.

For example, for the first signal resource set, time unit offset values corresponding to each value of the time-frequency parameter are configured, and the time unit offset values corresponding to different values of the time-frequency parameter may be the same or different. Note that for a given first set of signal resources, the base station may configure a slot offset value for some values of the time-frequency parameter and not configure a slot offset value for other values of the time-frequency parameter.

3. And determining a time unit offset value based on the time-frequency parameter, the trigger state corresponding to the DCI and the first signal resource.

For example, the base station may configure or pre-configure a time frequency parameter, a trigger state corresponding to the DCI, and an association relationship between the first signal resource and the time unit offset value, and after determining the time frequency parameter, the trigger state corresponding to the DCI, and the first signal resource, the terminal determines the time unit offset value according to the time frequency parameter, the trigger state corresponding to the DCI, and the association relationship between the first signal resource and the time unit offset value.

When the base station configures the association relationship:

for a given time-frequency parameter and a trigger state corresponding to the DCI, a time unit offset value corresponding to the first signal resource may be configured for each first signal resource configuration, and the time unit offset values corresponding to different first signal resources may be the same or different. Note that for a given time-frequency parameter and DCI corresponding trigger state, the base station may configure a slot offset value for a portion of the first signal resources and not configure a slot offset value for a portion of the first signal resources.

And configuring the same time unit offset value for all the first signal resources according to the given time-frequency parameter and the trigger state corresponding to the DCI.

In addition, the network device may also configure a time unit offset value for the trigger state corresponding to the time-frequency parameter or the DCI, which is not described herein again.

For example, for the first signal resource and the trigger state corresponding to the DCI, a time unit offset value corresponding to each value of the time-frequency parameter is configured, and the time unit offset values corresponding to different values of the time-frequency parameter may be the same or different. Note that, for a given first signal resource and a trigger state corresponding to DCI, the base station may configure a timeslot offset value for some values of the time-frequency parameter and not configure a timeslot offset value for other values of the time-frequency parameter.

For another example, for the first signal resource and the time-frequency parameter, a time unit offset value corresponding to each value of the trigger state corresponding to the DCI is configured, and time unit offset values corresponding to different values of the trigger state corresponding to the DCI may be the same or different. Note that for a given first signal resource and time-frequency parameter, the base station may configure a slot offset value for a part of values of the trigger state corresponding to the DCI, and not configure a slot offset value for other values of the trigger state corresponding to the DCI.

4. And determining a time unit offset value based on the time-frequency parameter, the trigger state corresponding to the DCI and the first signal resource set.

For example, the time frequency parameter, the trigger state corresponding to the DCI, the association relationship between the first signal resource set and the time unit offset value may be configured or preconfigured by the base station, and after the time frequency parameter, the trigger state corresponding to the DCI, and the first signal resource set are determined, the terminal determines the time unit offset value according to the association relationship between the time frequency parameter, the trigger state corresponding to the DCI, the first signal resource set, and the time unit offset value.

When the base station configures the association relationship:

for a given time-frequency parameter and a trigger state corresponding to the DCI, a time unit offset value corresponding to the first signal resource set may be configured for each first signal resource configuration, and the time unit offset values corresponding to different first signal resources may be the same or different. Note that for a given time-frequency parameter and DCI corresponding trigger state, the base station may configure a slot offset value for a portion of the first signal resources and not configure a slot offset value for a portion of the first signal resources.

For a given time-frequency parameter and a trigger state corresponding to the DCI, time unit offset values corresponding to the first signal resource set may be configured for each first signal resource set, where the time unit offset values corresponding to different first signal resource sets may be the same or different, and the time unit offset values corresponding to all first signal resources in the same first signal resource set are the same.

In addition, the network device may also configure the time unit offset value for the trigger state corresponding to the time-frequency parameter or the DCI, which is not described herein again.

For example, for the first signal resource set and the trigger state corresponding to the DCI, time unit offset values corresponding to each value of the time-frequency parameter are configured, and the time unit offset values corresponding to different values of the time-frequency parameter may be the same or different. Note that for a given first set of signal resources, the base station may configure a slot offset value for some values of the time-frequency parameter and not configure a slot offset value for other values of the time-frequency parameter.

The following further describes the methods in the above embodiments by taking CC identification as a time-frequency parameter as an example:

And the UE detects Downlink Control Information (DCI) according to the PDCCH configuration information, and if a piece of DCI is detected to comprise the SRS triggering signaling, the time domain transmission position of the SRS triggered by the triggering signaling is determined according to the identification of the CC where the PDCCH for transmitting the DCI is located.

For another example, the base station groups the values of the CC identifiers and indicates the slot offset value of the SRS/SRS resource set for each group.

For another example, the base station groups the values of the CC identifier and indicates a second slot offset value of the SRS/SRS resource set for each group, where the slot offset value is the first slot offset value plus the second slot offset value configured for the SRS resource/SRS resource set by the base station.
