Detailed Description

All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.

The technical scheme of the invention can be applied to various communication systems, such as: global System for mobile communications (GSM), Code Division Multiple Access (CDMA) System, Wideband Code Division Multiple Access (WCDMA), General Packet Radio Service (GPRS), Long Term Evolution (LTE)/enhanced Long Term Evolution (LTE-a), New air interface for mobile communications (New Radio, NR), and the like.

User Equipment (UE), also referred to as Mobile Terminal (Mobile Terminal), Mobile User Equipment (ms), etc., may communicate with one or more core networks via a radio access Network (e.g., RAN, radio access Network), and may be Mobile terminals, such as Mobile phones (or "cellular" phones) and computers having Mobile terminals, such as portable, pocket, hand-held, computer-included, or vehicle-mounted Mobile devices, that exchange language and/or data with the radio access Network.

The Base Station may be a Base Transceiver Station (BTS) in GSM or CDMA, a Base Station (NodeB) in WCDMA, an evolved Node B (eNB or e-NodeB) in LTE, and a 5G Base Station (gNB), but the present invention is not limited thereto, and for convenience of description, the following embodiments take the gNB as an example for description.

The technical solutions provided by the embodiments of the present invention are described in detail below with reference to the accompanying drawings.

Example 1

Fig. 1 is a schematic flow chart of a method for determining a reference signal according to embodiment 1 of the present invention, and referring to fig. 1, the method may specifically include the following steps:

step 12, the gNB sends configuration information/trigger information to the UE;

it should be noted that, one implementation manner of step 12 may be:

the gNB sends configuration information to the UE, where the configuration information is used to configure information required for sending the uplink SRS to the UE, and for example: for the P-SRS in the periodic P-SRS, the semi-continuous SP-SRS and the non-periodic AP-SRS, the gNB can configure information such as an antenna port, frequency, transmission period and the like for the UE through the RRC message and instruct the UE to transmit the uplink SRS.

Another implementation of step 12 may be:

and the gNB sends trigger information to the UE, wherein the trigger information is used for triggering the configuration information pre-configured to the UE by the gNB. For example: the pre-configured configuration information may include: when the UE is required to transmit the SP-SRS, the configuration information corresponding to the SP-SRS can be triggered only.

Step 14, the UE determines a first RS from the candidate set of the reference signal RS by adopting an agreed mode;

it should be noted that, one implementation manner of step 14 may be:

after receiving the indication information, the UE determines a candidate set of candidate RSs according to the convention with the gNB and based on the type of the uplink SRS sent by the gNB indication UE, and then selects one RS from the candidate set as a first RS.

Referring to fig. 2, another implementation of step 14 may be:

after receiving the indication information, the UE determines a candidate set of candidate RSs based on the type of the uplink SRS sent by the UE indicated by the gNB and the type of the UE according to the convention with the gNB, and then selects one RS from the candidate set as a first RS. The UE has two types, a first type for indicating that the UE has the capability of transceiving beam consistency, and a second type for indicating that the UE does not have the capability of transceiving beam consistency.

Referring to fig. 2, step 14 is described in detail below, by way of example:

step 22, determining candidate RSs corresponding to the type of the uplink SRS and the type of the UE

It should be noted that, one implementation manner of step 141 may be:

determining a candidate set of candidate RSs based on a spatial relationship, i.e. a corresponding relationship of beams, between a reference RS (downlink CSI-RS/SSB or uplink SRS) and an uplink SRS, which needs to be indicated, specifically referring to the following table:

wherein A represents a period; SP represents semi-persistent; AP represents aperiodic; the CSI-RS denotes a channel state information reference signal.

For example, if the uplink SRS is a semi-persistent SRS and the UE does not have the capability of beam transceiving consistency, referring to the table above, the corresponding candidate RSs may be: one or more of a P-SRS, a SP-SRS, and an AP-SRS.

Step 24, performing uplink/downlink beam training

Determining whether the UE and the gNB have the capability of transceiving consistency, and if so, performing downlink beam training to determine at least one optimal transceiving beam pair, where the transceiving beam pair includes a receiving beam of the UE, that is, a transmitting beam, and a resource indicator corresponding to the receiving beam, for example: CRI, CRI-RS; also included is a transmit beam, i.e., a receive beam, of the gNB and its corresponding resource indication.

If not, uplink beam training is required to determine at least one optimal transmit-receive beam pair, wherein the transmit-receive beam pair comprises a transmit beam of the UE and a resource indication corresponding to the transmit beam; one receive beam of the gNB is also included, along with its corresponding resource indication.

The process of the uplink beam training is briefly described as follows:

the first uplink beam training mode: the gNB may set a set of SRS resources (SRS resources) in each of which the UE transmits SRS using a different beam direction. The gNB measures the SRS of the received SRS resource in each direction to determine the optimal one or more beam directions, and notifies the UE of the corresponding SRS Resource Indicator (SRI). For the first mode, the gNB may indicate the SRI to the UE, and the UE may transmit a set of SRS resources to perform finer uplink beam training using a beam near a UE transmission beam corresponding to the SRI, or transmit the SRS with the beam to perform uplink CSI measurement.

And a second uplink beam training mode: when the UE has a receive/transmit beam consistency (correlation result), the UE performs beam training according to a downlink beam training reference Signal, CSI-RS and/or SSB (Synchronization Signal Block), and reports resource indications (such as CRI, CSI-RS resource indications) corresponding to one or more determined optimal downlink receive beams, which are optimal uplink transmit beams, to the gNB. For the second way, the gNB may indicate a certain CRI reported by the UE to the UE, and the UE may transmit a set of SRS resources to perform finer uplink beam training using a beam near a UE transmission beam corresponding to the CRI, or transmit an SRS with the beam to perform uplink CSI measurement.

In addition, the method, before knowing that the uplink SRS is of a periodic or semi-continuous type and the first RS is an AP-CSI-RS, of the gNB before sending the first indication information to the ue, further includes:

sending sixth indication information to the user equipment, wherein the sixth indication information is used for indicating the UE to perform beam training corresponding to a third RS; the third RS is at least one of a synchronization signal block SSB, periodic channel state information P-CSI-RS, semi-continuous channel state information SP-CSI-RS, periodic SRS and semi-continuous SRS.

Based on this, if the gNB sends the DCI carrying the first indication information to the UE through the PDCCH, and the first RS indicated by the first indication information is the AP-CSI-RS, when the UE does not receive the DCI, a problem of transmission reliability may occur. Therefore, in this embodiment, the UE is instructed to perform training of the third RS, so that when the DCI is not received, one reference signal of the latest beam training of at least one of the SSB, the P-CSI-RS, the SP-CSI-RS, the P-SRS, and the SP-SRS is used, and the uplink SRS is transmitted by using the transmission beam of the reference signal.

It is understood that step 144 may be performed before step 142, after step 142, or partially before step 142 and partially after step 142.

Step 26, selecting a first RS from the candidate set;

when the UE transmits the uplink SRS to the gNB based on the instruction from the gNB, the first RS is selected from the candidate set based on the agreement with the gNB.

The step of selecting the first RS from the candidate set may specifically be:

and determining the RS adopted by the user equipment in the last beam training from the candidate set.

Or comparing the results of the beam training corresponding to each RS in the candidate set from dimensions such as signal strength to determine an optimal transmission beam, and using the RS corresponding to the optimal transmission beam as the first RS.

Step 16, the UE transmits the uplink SRS to the gNB by adopting the transmission beam corresponding to the first RS;

the transmission beam for transmitting the uplink SRS may be a transmission beam of the UE in any one of the transmission/reception beam pairs trained by the first RS, and is preferably an optimal transmission/reception beam pair.

Step 18, the gNB determines a first RS from the candidate set of RSs in an agreed manner;

it should be noted that the implementation manner of determining the first RS by the gNB is similar/identical to the implementation manner of determining the first RS by the UE, and therefore, the description of step 18 is not repeated here.

However, it is to be understood that step 18 may occur before step 12, after step 16, etc., and is disposed after step 16 herein for illustrative purposes only and is not to be construed as limiting.

Step 110, the gNB receives the uplink SRS sent by the UE by adopting the receiving beam corresponding to the first RS;

in step 18, the gNB may select a receiving beam corresponding to the resource indication from the receiving beams corresponding to the first RS based on the resource indication corresponding to the transmitting beam used by the UE.

In addition, the steps 12, 14 and 18 are optional steps.

As can be seen, in this embodiment, the reference signal used by the UE can be determined by the gNB by using an agreed manner; furthermore, when the UE transmits the uplink SRS using the transmission beam corresponding to the identified RS, the gNB can clearly know the RS corresponding to the transmission beam used by the US, and can further receive the uplink SRS using the corresponding reception beam, thereby avoiding the problem that the transmission beam used when the UE transmits the uplink SRS does not coincide with the transmission beam understood by the gNB.

Example 2

Fig. 3 is a schematic flowchart of a method for determining a reference signal according to embodiment 2 of the present invention, and referring to fig. 3, the method may specifically include the following steps:

step 32, the gNB sends first indication information to the UE;

the first indication information is used for indicating a first RS corresponding to a transmission beam of an uplink SRS of the UE.

It should be noted that, one implementation manner of step 32 may be:

the gNB can send first indication information to the UE through an RRC message;

or, sending the first indication information to the UE through the MAC CE message;

or sending the DCI carrying the first indication information to the UE through a downlink physical control channel (PDCCH).

Furthermore, when the uplink SRS is a P-SRS, the gNB preferably transmits the first indication information by using an RRC message; when the uplink SRS is the SP-SRS or the AP-SRS, the gNB preferably adopts the MAC CE to send first indication information; and when the uplink SRS is the AP-SRS, the gNB optionally sends the DCI carrying the first indication information to the user equipment through the PDCCH.

Step 34, the UE transmits the uplink SRS to the gNB by using the transmission beam corresponding to the first RS;

the UE determines the first RS based on the first indication information of the gNB, and then transmits the uplink SRS using the transmission beam corresponding to the first RS.

And step 36, the gNB receives the uplink SRS sent by the UE.

It should be noted that, one implementation manner of step 36 may be:

the gNB uses the receiving beam corresponding to the first RS to receive the uplink SRS sent by the UE;

alternatively, other available receiving beams are used to receive the uplink SRS transmitted by the UE.

As can be seen, in the embodiment, the reference signal used by the UE can be determined by the gNB by sending the indication information to the UE through the gNB.

In order to reduce signaling overhead, if the first RS is aperiodic channel state information AP-CSI-RS, after step 22, the gNB may further send third indication information to the UE, where the third indication information is used to indicate, to the UE, a time at which the gNB sends the first RS, and indicate the UE to send the AP-SRS, so as to implement joint triggering.

Furthermore, before or simultaneously with sending the third indication information, the gNB may also send fourth indication information to the UE, where the fourth indication information is used to instruct the UE to determine the sending time of the uplink SRS. For example: setting a time interval between the UE sending the AP-SRS to the gNB and the gNB sending the third indication information to the UE, or setting a time interval between the UE sending the AP-SRS to the gNB and the gNB sending the AP-CSI-RS to the UE, wherein the time interval can be specifically: spaced X OFDM symbols apart. In this way, the UE can determine the time to transmit the uplink SRS to the gNB based on the fourth indication information.

The specific step of sending the fourth indication information may be:

and before the third indication information is sent to the user equipment, sending fourth indication information to the UE through an RRC message or an MAC CE message. It is to be understood that the fourth indication information may be transmitted to the UE through an RRC message or a MAC CE message along with the configuration as part of the configuration information.

Alternatively, the first and second electrodes may be,

and sending DCI carrying fourth indication information to the user equipment through the PDCCH while sending the third indication information to the user equipment.

Moreover, compared with the present embodiment, in the prior art, after the indication information for indicating the time when the gNB transmits the first RS to the UE is transmitted, the indication information for indicating the UE to transmit the AP-SRS to the gNB needs to be transmitted again, and the present embodiment does not need other signaling to trigger the UE to transmit the AP-SRS, thereby saving signaling overhead.

In order to further improve the flexibility of instructing the association between the RS and the uplink SRS, after step 22, the gNB may further transmit, to the UE, fifth instruction information for instructing the UE to change the first RS corresponding to the transmission beam of the uplink SRS to the second RS.

In addition, steps 34 and 36 are optional steps.

It is understood that the fifth indication information and the first indication information may be the same type of indication information in chronological order, except that the indicated RS is different. When receiving a plurality of pieces of instruction information of this type, the UE transmits the uplink SRS with a transmission beam corresponding to the RS indicated by the instruction information received most recently.

Example 3

Fig. 4 is a flowchart illustrating a method for sending an uplink sounding reference signal according to embodiment 3 of the present invention, referring to fig. 4, where the method may be executed by a UE, and specifically may include the following steps:

step 42, determining a first RS from the candidate set of reference signals RS by adopting an agreed mode;

and step 44, sending the uplink SRS to the network device by using the sending beam corresponding to the first RS.

It should be noted that, before step 42, the method further includes:

and determining a candidate set of candidate RSs based on the type of the uplink SRS.

And second indication information is sent to the network equipment, the second indication information is used for indicating the type of the user equipment, and the type of the user equipment is used for determining whether the user equipment has the capability of transmitting and receiving beam consistency.

Wherein determining a candidate set of candidate RSs based on the type of the uplink SRS comprises:

determining a candidate set of candidate RSs based on the type of the uplink SRS and the type of the user equipment;

wherein the first RS is an RS adopted by the user equipment in the candidate set in the last beam training.

As can be seen, in this embodiment, the reference signal used by the UE can be determined by the gNB by using an agreed manner; furthermore, by transmitting the uplink SRS using the transmission beam corresponding to the identified RS at the UE, the gNB can clearly know the RS corresponding to the transmission beam used by the US, and can further receive the uplink SRS using the corresponding reception beam, thereby avoiding the problem that the transmission beam used when the UE transmits the uplink SRS does not coincide with the transmission beam understood by the gNB.

Example 4

Fig. 5 is a flowchart illustrating a method for sending an uplink sounding reference signal according to embodiment 4 of the present invention, referring to fig. 5, where the method may be executed by a UE, and specifically may include the following steps:

step 52, receiving first indication information from the network device, where the first indication information is used to indicate a first RS corresponding to a transmission beam of an uplink SRS of the user equipment;

it should be noted that, one implementation of step 52 may be:

receiving first indication information from the network equipment through an RRC message;

or, receiving first indication information from the network device through a MAC CE message;

or receiving the DCI carrying the first indication information from the network equipment through the PDCCH.

Wherein receiving the first indication information from the network device through the MAC CE message includes:

and if the type of the uplink SRS is semi-continuous or non-periodic, receiving first indication information from the network equipment through an MAC CE message.

Receiving, by the PDCCH, the DCI carrying the first indication information from the network device includes:

and if the uplink SRS type is non-periodic, receiving the DCI carrying the first indication information from the network equipment through the PDCCH.

And step 54, sending the uplink SRS to the network device by using the sending beam corresponding to the first RS.

Preferably, after step 52, the method further comprises:

and if the first RS is the AP-CSI-RS, receiving third indication information from the network equipment, wherein the third indication information is used for indicating the time when the network equipment sends the first RS and indicating the user equipment to send the aperiodic uplink SRS.

In addition, before or while receiving the first indication information from the network device corresponding to the third indication information, the method further includes: receiving fourth indication information from the network device, where the fourth indication information is used to indicate the user equipment to determine a transmission time of the uplink SRS.

Wherein the fourth indication information from the network device may be received through an RRC message or a MAC CE message before the third indication information from the network device is received;

or, receiving the third indication information from the network device, and simultaneously receiving the DCI carrying the fourth indication information from the network device through the PDCCH.

Preferably, after step 52, the method further comprises:

and receiving fifth indication information from the network device, where the fifth indication information is used to indicate a user equipment to change a first RS corresponding to a transmission beam of the uplink SRS to a second RS.

Preferably, before step 52, the method further comprises:

receiving sixth indication information from the network device, where the sixth indication information is used to indicate the user equipment to perform beam training corresponding to a third RS; the third RS is at least one of a synchronization signal block SSB, periodic channel state information P-CSI-RS, semi-continuous channel state information SP-CSI-RS, periodic SRS and semi-continuous SRS.

As can be seen, in the embodiment, the reference signal used by the UE is determined by the way that the gNB sends the first indication information to the UE; moreover, when the UE transmits the uplink SRS by using the transmission beam corresponding to the RS indicated by the first indication information, the gNB can clearly know that the RS corresponding to the transmission beam used by the US is, and further, the uplink SRS can be received by using the corresponding reception beam, so that the problem that the transmission beam used when the UE transmits the uplink SRS is not consistent with the transmission beam understood by the gNB is avoided, and the flexibility of indicating the correspondence between the RS and the uplink SRS is improved.
