The embodiment of the invention provides a method for sending uplink detection pilot frequency, which is applied to terminal equipment. Referring to fig. 3, fig. 3 is a flowchart of a method for transmitting uplink sounding pilot according to an embodiment of the present invention, as shown in fig. 3, including the following steps:

step 301, in a case where N slot resources are configured in a transmission period configured for uplink data, transmitting an uplink sounding pilot SRS on at least one slot resource in which a channel is in an idle state in the N slot resources;

In this embodiment, the uplink data may include, but is not limited to, a physical uplink control channel (Physical Uplink Control Channel, PUCCH), a physical uplink shared channel (Physical Uplink Sharing Channel, PUSCH), and the like.

The N timeslot resources may also be referred to as N repeated timeslot resources, which may be used for transmitting uplink data, that is, uplink data may be transmitted through the N timeslot resources in each transmission period. For example, referring to fig. 4a to 4d, slot resources identified by diagonal lines in each period may be used for uplink data transmission. Specifically, the repeated resource value N, that is, the N timeslot resources, may be configured for the terminal device by the network side device.

The N time slot resources may be located in an unlicensed frequency band (NRU), so that it is necessary to monitor whether a channel is idle or in an idle state first in case of transmitting uplink data using the N time slot resources, and transmit the uplink data in case of the channel being idle (i.e., the channel being in an idle state).

It should be noted that, the N time slot resources may be consecutive N time slot resources, as shown in fig. 4a; or the N time slot resources are discrete, namely the N time slot resources are not adjacent to each other; or may be continuous between the partial time slot resources and discrete between the partial time slot resources, as shown in fig. 4d, which is not limited in this embodiment.

The above-mentioned M slot resources may also be referred to as M repeated slot resources, which may be used for SRS transmission, that is, the SRS may be transmitted through the above-mentioned M slot resources in each transmission period. For example, referring to fig. 4c and 4d, slot resources including dot identifications in each period may be used for SRS transmission. Specifically, the repeated resource value M, that is, the above M slot resources, may be configured for the terminal device by the network side device. The M time slot resources belong to the N time slot resources. The M time slot resources may be continuous M time slot resources, discrete M time slot resources, or continuous between partial time slot resources, and discrete between partial time slot resources, which is not limited in this embodiment.

In an embodiment, if the M slot resources are not configured, for example, only the period and offset are configured for the SRS according to the conventional SRS configuration manner, as shown in fig. 4a and fig. 4b, when the channel of the slot resource configured for SRS transmission is in an occupied state, the SRS may be transmitted through at least one slot resource that is different from the slot resource configured for SRS transmission and has an idle state in the N slot resources, so that not only the SRS transmission opportunity may be increased, but also the SRS transmission efficiency may be improved, and the configuration complexity may be reduced.

In another embodiment, if the M slot resources are configured, as shown in fig. 4c and fig. 4d, the SRS may be transmitted using at least one slot resource with an idle channel among the M slot resources, so that not only the SRS transmission opportunity may be increased, but also the SRS transmission efficiency may be further improved, and the flexibility of uplink resource configuration for SRS transmission may be improved.

Optionally, the at least one slot resource is a slot resource different from a slot resource configured for the SRS transmission;

the sending the uplink sounding pilot SRS on at least one timeslot resource with a channel in an idle state in the N timeslot resources includes:

If the channel of the first time slot resource in the transmission period is in an occupied state and the channel of the second time slot resource in the transmission period is in an idle state, transmitting the SRS on the second time slot resource;

the first time slot resource is configured as a time slot resource used for SRS transmission, and the second time slot resource is a time slot resource located after the first time slot resource in the N time slot resources.

In this embodiment, the network side device may configure resources for SRS according to an existing SRS resource configuration manner, for example, configure periods and offsets for SRS according to the same SRS resource configuration manner as NR Rel-15.

When the terminal equipment monitors that the channel is in an idle state (i.e. the channel of the first time slot resource is in an idle state) on the time slot resource (i.e. the first time slot resource) configured for the SRS, the SRS can be sent by using the first time slot resource; in the case that the channel is monitored to be in the occupied state on the first time slot resource, the channel can be continuously monitored on the time slot resource located behind the first time slot resource in the N time slot resources, and the SRS is sent by utilizing the time slot resource with the channel state in the idle state, in this case, the time slot in which the terminal device actually sends the SRS is different from the configured time slot, as shown in fig. 4 b.

Alternatively, if the number of the second slot resources is at least two, part or all of the at least two slot resources may be used to transmit SRS.

Optionally, a priority relationship corresponding to each of the at least N timeslot resources may be predefined by a protocol or configured by a network side, where the priority relationship is used to indicate priorities of SRS and uplink data transmission. In this way, the above-mentioned transmitting the SRS on the second slot resource may include transmitting the SRS on the second slot resource when the priority relation corresponding to the second slot resource indicates that the priority of the SRS is higher than that of the uplink data, otherwise, not transmitting the SRS on the second slot resource.

In this embodiment, when the configured slot resource channel for SRS transmission is in an occupied state, the SRS is transmitted through the slot resource, which is located after the configured slot resource for SRS transmission and has an idle state, in the N slot resources, so that not only can the SRS transmission opportunity be increased, but also the SRS transmission efficiency can be improved, and the configuration complexity can be reduced.

Optionally, the sending the SRS on the second slot resource may include:

And transmitting the SRS on the second time slot resource according to the resource configuration information of the SRS.

In this embodiment, the resource configuration information of the SRS may include, but is not limited to, configuration information of time domain resources, frequency domain resources, and the like. Alternatively, the SRS may be transmitted on the second slot resource according to other configuration information than the slot resource location of the SRS in the resource configuration information of the SRS, for example, the SRS may be transmitted on the configured bandwidth and on the same symbol as the configured symbol location in the second slot resource.

In the embodiment, the SRS is sent on the second time slot resource based on the resource configuration information of the SRS, so that the complexity of configuring the SRS resource can be reduced.

Optionally, the at least one slot resource is a slot resource of M slot resources configured for the SRS transmission;

and if the channel is in an idle state on a third time slot resource in the M time slot resources, sending the SRS on the third time slot resource.

In this embodiment, the terminal device configures M slot resources for SRS transmission to improve SRS transmission efficiency, as shown in fig. 4c and fig. 4 d. Alternatively, the network side device may configure the period, offset and repetition resource value M of the SRS for the terminal device.

Optionally, the terminal device may perform channel monitoring on the timeslot resources in the M timeslot resources in sequence until a channel in an idle state is monitored. The third slot resource may be any slot resource of the M slot resources, and when the third slot resource monitors that the channel is in an idle state, the SRS may be transmitted on the third slot resource.

Alternatively, the embodiment may only transmit the SRS on the third slot resource, that is, none of the M slot resources located after the third slot resource is transmitting the SRS; the SRS may be transmitted on the third slot resource and on a slot resource located after the third slot resource and in an idle state among the M slot resources.

Optionally, the priority relationship corresponding to the third timeslot resource may indicate that the priority of the SRS is higher than the priority of the uplink data, that is, when the channel is monitored to be in an idle state on the third timeslot resource and the priority relationship corresponding to the third timeslot resource indicates that the priority of the SRS is higher than the priority of the uplink data, the SRS is transmitted on the third timeslot resource.

Optionally, the method may further include one of:

If a fourth time slot resource exists, the SRS is sent on the fourth time slot resource, wherein the fourth time slot resource is a time slot resource which is positioned behind the third time slot resource in the M time slot resources and has an idle channel state;

and if a fifth time slot resource exists and the uplink data transmission does not exist in a first symbol of the fifth time slot resource, transmitting the SRS on the first symbol, wherein the fifth time slot resource is a time slot resource which is positioned behind the third time slot resource in the M time slot resources and has an idle channel state, and the first symbol is a configured symbol used for transmitting the SRS.

In an embodiment, if there are time slot resources (i.e., fourth time slot resources) located after the third time slot resource and having an idle channel, the SRS may be further transmitted on the fourth time slot resource, that is, the SRS is transmitted on both the third time slot resource and the fourth time slot resource, so as to improve the SRS transmission efficiency.

In another embodiment, if the fifth timeslot resource exists in the M timeslot resources and the first symbol of the fifth timeslot resource does not have uplink data transmission, the SRS may also be transmitted on the first symbol of the fifth timeslot resource, that is, the SRS is transmitted on both the third timeslot resource and the fifth timeslot resource, so as to improve the SRS transmission efficiency. If there is uplink data transmission in the first symbol of the fifth slot resource, the SRS may not be transmitted in the fifth slot resource, so that priority transmission of uplink data may be ensured.

Optionally, if the M slot resources are consecutive M slot resources, when the channel is monitored to be in an idle state on the third slot resource, if the slot resource located behind the third slot resource exists in the M slot resources, the SRS may be directly transmitted on the slot resource, without performing channel monitoring on the slot resource.

Optionally, the priority relationship corresponding to each time slot resource in the at least one time slot resource indicates that the priority of the SRS is higher than the priority of the uplink data.

In this embodiment, the SRS may be transmitted only on the slot resources where the channel is in an idle state and the corresponding priority relationship indicates that the priority of the SRS is higher than the priority of the uplink data, so that the SRS transmission may be ensured.

Optionally, the priority relationship corresponding to each time slot resource of the M time slot resources is predefined for a protocol or configured by a network side.

In this embodiment, the priority relationship corresponding to each time slot resource of the M time slot resources may be reasonably set according to actual requirements, for example, the priority relationship corresponding to a part of time slot resources may exist in the M time slot resources to indicate that the priority of the SRS is higher than the priority of the uplink data, or the priority relationship corresponding to a part of time slot resources may exist to indicate that the priority of the SRS is lower than the priority of the uplink data; or the priority relations corresponding to all the time slot resources in the M time slot resources indicate that the priority of the SRS is higher than the priority of the uplink data; or the priority relationships corresponding to all the time slot resources in the M time slot resources indicate that the priority of the SRS is lower than the priority of the uplink data.

According to the embodiment, the priority relation corresponding to each time slot resource of the M time slot resources is set, so that the transmission of SRS and uplink data can be controlled flexibly.

It should be noted that, the foregoing embodiments may be reasonably combined according to actual needs, which is not limited in this embodiment.

The embodiment of the invention provides an uplink detection pilot frequency receiving method which is applied to network side equipment. Referring to fig. 5, fig. 5 is a flowchart of an uplink sounding pilot receiving method according to an embodiment of the present invention, as shown in fig. 5, including the following steps:

In this embodiment, the uplink data may include, but is not limited to, PUCCH, PUSCH, and the like.

The above-mentioned N slot resources may also be referred to as N repeated slot resources, which may be used for uplink data transmission, for example, referring to fig. 4a to 4d, the slot resources identified by diagonal lines in each period may be used for uplink data transmission. Specifically, the network side device may configure the terminal device with a repetition resource value N, that is, the N timeslot resources. Wherein, the N time slot resources can be located in an unlicensed frequency band.

The above-mentioned M slot resources may also be referred to as M repeated slot resources, which may be used for SRS transmission, for example, referring to fig. 4c and fig. 4d, the slot resources including dot marks in each period may be used for SRS transmission. Specifically, the network side device may configure the terminal device with a repetition resource value M, that is, the M timeslot resources. The M time slot resources belong to the N time slot resources. The M time slot resources may be continuous M time slot resources, discrete M time slot resources, or continuous between partial time slot resources, and discrete between partial time slot resources, which is not limited in this embodiment.

In an embodiment, if the network side device does not configure the M slot resources for the SRS, for example, the network side device configures only a period and an offset for the SRS according to the existing SRS configuration manner, as shown in fig. 4a and fig. 4b, the network side device may receive the SRS from at least one slot resource different from the configured slot resource for SRS transmission in the N slot resources, so that not only the SRS receiving opportunity may be increased, but also the SRS receiving efficiency may be improved, and the configuration complexity may be reduced.

In another embodiment, if the network side device configures the M slot resources for SRS, as shown in fig. 4c and fig. 4d, the SRS may be received from at least one slot resource of the M slot resources, so that not only the reception opportunity of the SRS may be increased, but also the efficiency of SRS reception may be improved, and the flexibility of uplink resource configuration for SRS transmission may be improved.

Alternatively, the network side device may attempt to receive SRS only on the second slot resource where uplink transmission is detected.

Alternatively, the present embodiment may receive the SRS only from the second slot resource indicating that the priority of the SRS is higher than the priority of the uplink data from the corresponding priority relationship.

In this embodiment, when the channel of the configured slot resource for SRS transmission does not receive the SRS, the SRS is received from the slot resource located after the configured slot resource for SRS transmission in the N slot resources, so that not only the reception opportunity of the SRS can be increased, but also the efficiency of SRS reception can be improved, and the complexity of configuration can be reduced.

Optionally, the receiving the SRS on the second slot resource of the transmission period includes:

and receiving the SRS on the second time slot resource according to the resource configuration information of the SRS.

Optionally, the network side device may configure the SRS period, offset, and repetition resource value M for the terminal device.

In this embodiment, the network side device may retry receiving the SRS from the third slot resource when detecting that there is an uplink transmission on the third slot resource.

Optionally, the network side device may stop receiving the SRS on a slot resource subsequent to the third slot resource if the SRS is successfully received on the third slot resource; the SRS may also be continuously received from a slot resource subsequent to the third slot resource if the SRS is successfully received on the third slot resource.

Alternatively, the network side device may only receive the SRS in the timeslot resources whose priority relationship corresponding to the M timeslot resources indicates that the priority of the SRS is higher than the priority of the uplink data.

Optionally, the method may further include one of:

if a fourth time slot resource exists, receiving the SRS on the fourth time slot resource, wherein the fourth time slot resource is a time slot resource positioned behind the third time slot resource in the M time slot resources;
