Description

Beam processing method, device, terminal and network side equipment

Technical Field

The present invention relates to the field of communications technologies, and in particular, to a method, an apparatus, a terminal, and a network device for processing a beam.

Background

In view of the important role of MIMO (Multiple-Input Multiple-Output) technology in improving peak rate and system spectrum utilization, wireless access technology standards such as LTE (Long Term Evolution)/LTE-a (LTE-Advanced Evolution) are constructed based on MIMO + OFDM (Orthogonal frequency division Multiplexing) technology. The performance gain of the MIMO technology comes from the space freedom degree that can be obtained by the multi-antenna system, so that one of the most important evolution directions of the MIMO technology in the standardization development process is the extension of dimension.

In LTE Rel-8, MIMO transmission of up to 4 layers can be supported. The Rel-0 is used for enhancing an MU-MIMO (Multi-user MIMO, Multi-user multiple input multiple output) technology, and the MU-MIMO Transmission in TM (Transmission Mode) -8 can support 4 downlink data layers at most. Rel-10 introduces ports supporting 8 antennas to further improve the spatial resolution of channel state information, and further extend the transmission capability of SU-MIMO (Single-User MIMO, Single-User multiple input multiple output) to at most 9 data layers. FD-MIMO (Full Dimension-MIMO) technology support is introduced into 32 ports by Rel-13 and Rel-14, and beam forming in the Full Dimension and the vertical direction is realized.

In order to further improve the MIMO technology, a large-scale antenna technology is introduced into a mobile communication system. For a base station, a fully digital large scale antenna may have up to 128/256/512 antenna elements and up to 128/256/512 transceiver elements, one connected to each antenna element. By transmitting pilot signals of up to 128/256/512 antenna ports, the terminal is caused to measure and feed back channel state information. For terminals, antenna arrays of up to 32/64 antenna elements may also be configured. And a huge beam forming gain is obtained by beam forming at two sides of the base station and the terminal so as to make up for signal attenuation caused by path loss. Especially in high frequency band communication, such as 30GHz frequency point, the path loss makes the coverage of wireless signals extremely limited. By the large-scale antenna technology, the coverage range of wireless signals can be expanded to a practical range.

The full digital antenna array, each antenna unit has an independent transceiver unit, which will greatly increase the size, cost and power consumption of the device. Especially for an analog-to-digital converter (ADC) and a digital-to-analog converter (DAC) of a transceiving unit, the power consumption is reduced by about 1/10 in the last decade, and the performance improvement is limited. In order to reduce the size, cost and power consumption of the device, a technical scheme based on analog beamforming is proposed, as shown in fig. 1 and 2, a transmitting end and a receiving end respectively have N_tAnd N_rAnd a transceiver unit. The analog beamforming is mainly characterized in that intermediate frequency (figure 1) or radio frequency signals (figure 2) are weighted and shaped through phase shifters. The advantages are that all transmitting (receiving) antennas only have one receiving/transmitting unit, the realization is simple, and the cost, the size and the power consumption are reduced.

In order to further improve the analog beamforming performance, a digital analog hybrid beamforming transceiving architecture scheme is proposed, as shown in fig. 3. In FIG. 3, the transmitting end and the receiving end have

And

number of individual transmitting/receiving units, transmitting-end antenna unitsNumber of antenna units at receiving end

The maximum parallel transmission stream number supported by the beam forming is min

The hybrid beamforming architecture of fig. 3 balances the flexibility of digital beamforming with the low complexity of analog beamforming, with support for multiple data streams and multiple usesThe ability of user simultaneous forming, and simultaneously, the complexity is controlled within a reasonable range.

In fig. 1, 2, and 3, PA refers to a power amplifier; LNA refers to a low noise amplifier.

Both analog beamforming and digital-analog hybrid beamforming require adjustment of analog beamforming weights at both the transmitting and receiving ends, so that a beam formed by the analog beamforming and the digital-analog hybrid beamforming can be aligned to the opposite end of communication. For downlink transmission, the beamforming weight sent by the base station side and the beamforming weight received by the terminal side need to be adjusted, and for uplink transmission, the beamforming weight sent by the terminal side and received by the base station side need to be adjusted. The beamforming weights are typically obtained by transmitting training signals. In the downlink direction, the base station sends a downlink beam training signal, the terminal measures the downlink beam training signal, selects the best base station sending beam, feeds back the information related to the beam to the base station, and selects the corresponding best receiving beam to be stored locally.

A terminal equipped with multiple transmit antennas is able to perform uplink beamforming. To determine the uplink UL beamforming matrix, a terminal in an RRC _ CONNECTED state may be semi-statically configured with a plurality of terminal-specific uplink Sounding Reference Signal (SRS) resources. The SRS signals transmitted on each SRS resource are beamformed with a particular beamforming matrix. The terminal transmits these SRS resources in uplink. The TRP (transmitting and receiving node) measures the signal quality of different SRS resources and selects a preferred SRS resource. The TRP transmits an index (e.g., SRI, SRS resource indicator) of the selected SRS resource to the terminal via Downlink Control Information (DCI). From the SRI terminal it can be inferred which uplink beamforming matrix (e.g. SRS resource) the TRP recommends for future uplink transmissions. The terminal may then use the uplink beamforming matrix indicated by the SRI for future uplink transmissions.

A terminal may be configured with one or more antenna panels (panels, also referred to as fronts) for uplink transmission. Each antenna panel is composed of a set of antenna elements. The exact number of antenna panels, the number of antenna elements and the arrangement of the antenna elements within each panel is a matter of implementation and different terminals may have different implementations. A terminal may transmit one data layer at a time from one panel or the terminal may transmit one data layer simultaneously from a subset of antenna panels (including more than one antenna panel). The transmission scheme herein is also applied to the SRS resource (SRS signal transmission).

A terminal equipped with a single antenna panel may be configured with one SRS resource set (SRS resource set) for transmission beam scanning. Each SRS resource set includes multiple SRS resources, and different SRS resources use different beams for beamforming. The SRS resources within one set of SRS resources are transmitted at different times. The base station gNB receives the set of SRS resources and determines a preferred transmission beam (e.g., a transmission beam used by the SRS resource with the best reception quality) based on the received set of SRS resources.

For a terminal equipped with multiple antenna panels, the base station does not know the number of antenna panels of the terminal, and therefore, it is not possible to select an optimal transmission beam for each antenna panel, and it is also not possible to perform flexible uplink scheduling for each antenna panel, which affects the performance of uplink transmission.

It should be noted that the specific type of the terminal is not limited in the embodiment of the present invention.

It should be understood that a terminal, also referred to as a User Equipment (UE), a Mobile Station (MS), a Mobile Terminal (MT), etc., is a device that provides voice and/or data connectivity to a user, e.g., a handheld device with wireless connection capability, a vehicle-mounted device, etc. Currently, some examples of terminals are: a mobile phone (mobile phone), a tablet computer, a notebook computer, a palm top computer, a Mobile Internet Device (MID), a wearable device, a Virtual Reality (VR) device, an Augmented Reality (AR) device, a wireless terminal in industrial control (industrial control), a wireless terminal in self driving (self driving), a wireless terminal in remote surgery (remote medical supply), a wireless terminal in smart grid (smart grid), a wireless terminal in transportation safety (smart security), a wireless terminal in city (smart city), a wireless terminal in home (smart home), and the like.

As shown in fig. 4, an embodiment of the present invention provides a beam processing method applied to a terminal including multiple antenna panels, including:

and step 41, receiving the first indication information sent by the network side equipment.

In this step, the first indication information may be sent through a separate signaling, or may be carried through an existing signaling, for example, the first indication information is indicated through a higher layer parameter in RRC parameters configured by a network side device for a certain signal (for example, the signal may be an SRS for acquiring channel state information CSI), and the higher layer parameter may be "spatialrelalationinfo".

Optionally, the first indication information is sent through downlink control information DCI.

Optionally, the first indication information is sent through radio resource control RRC signaling.

Optionally, the first indication information is sent through MAC-CE signaling.

And step 42, determining a transmission beam corresponding to a first antenna panel of the terminal according to the first indication information.

In this step, the first indication information may directly indicate an index or an identifier of the transmission beam of the first antenna panel, or may indirectly indicate the transmission beam of the first antenna panel by indicating an index or an identifier of a certain resource (the resource has a correspondence with the transmission beam).

The first indication information in this step may indicate the transmission beam corresponding to the first antenna panel in a manner of indicating the reference signal.

For example, the network side device configures a set of source SRS resources for the terminal to perform uplink CSI acquisition. The terminal transmits the set of source SRS resources using the first antenna panel. When the network side equipment schedules the PUSCH signal, the terminal indicates one SRS resource (reference SRS resource) from the source SRS resource to the terminal through the SRI indicated by the SRS resource, which is equivalent to the transmission beam when the network side equipment indicates the transmission beam of the first antenna panel to the terminal as the transmission beam when the terminal transmits the reference SRS resource.

For another example, the network side device configures a set of source SRS resources for the terminal to perform uplink CSI acquisition. The terminal transmits the set of source SRS resources using the first antenna panel. The network side equipment sends SRS resource indication information to the terminal, and the SRS resource indication information is used for indicating one SRS resource (reference SRS resource) from the source SRS resource to the terminal. Through the SRS resource indication information, the network side equipment indicates the transmission beam of the first antenna panel to the terminal as the transmission beam when the terminal transmits the reference SRS resource.

For another example, in the 3GPP system, a target SRS Resource is configured with an SRS-spatialrelalationinfo parameter in the SRS-Resource parameter as in the TS38.331 protocol, which is as follows:

the first indication information corresponds to SRS-SpatialRelationInfo, which takes as an example that SRS-SpatialRelationInfo indicates a source SRS resource. When the terminal needs to transmit the target signal corresponding to the target SRS resource, it needs to first determine the SRS signal corresponding to the source SRS resource, and transmit the target signal using the antenna panel corresponding to the SRS signal and the transmission beam on those antenna panels. That is, the network side device indicates the first antenna panel and the transmission beam of the first antenna panel when transmitting the target SRS by indicating the source SRS resource.

The first antenna panel in the present invention includes, but is not limited to, 1 antenna panel.

And 43, determining the transmission beams of the antenna panels except the first antenna panel according to the relative relation between the transmission beam corresponding to the first antenna panel and the transmission beams of the plurality of antenna panels.

In this step, the terminal may derive the transmission beams of the L-th antenna panel of the second antenna panel and the third antenna panel … … based on the transmission beam of the first antenna panel. L is an integer greater than or equal to 2, and preferably, L may be a quantity value of the antenna panels included in the terminal, and L may also be smaller than the quantity value of the antenna panels included in the terminal.

It should be noted that, in the embodiment of the present invention, the transmission beam corresponding to the first antenna panel may be: the network side equipment selects a preferred transmitting beam for a first antenna panel of the terminal, and the subsequent terminal can use the preferred transmitting beam selected by the network side equipment for beamforming when transmitting the uplink signal by using the first antenna panel. Accordingly, the transmission beams of the antenna panels other than the first antenna panel may be: and the subsequent terminal uses the antenna panels except the first antenna panel to transmit the uplink signal, and uses the transmission beam of the antenna panel determined by the terminal to carry out beamforming.

Preferably, in the above embodiment of the present invention, the beam processing method further includes:

As an embodiment, the relative relationship between the transmission beams of the multiple antenna panels may be transparent to the network side device, that is, only the terminal knows the relative relationship, and the network side device does not know the relative relationship; alternatively, the network side device also knows the relative relationship between the transmit beams of the multiple antenna panels.

For example, the terminal knows the visual axis (b) of the antenna panel 1, 2,3, … … antenna panel L according to the deployment information of its antenna paneloresight) has a fixed angular rotation theta with respect to the base station (network-side device) and the direct path (line-of-sight) of the terminal₁,theta₂,theta₃,…theta_L. Assume that all antenna panels are of ULA configuration and that the angle of arrival of antenna panel 1 is theta₁Then the array response (or transmit beam) of the antenna panel 1 can be written as:

V₁＝[V₁(1),…V₁(Nt)]＝[1….exp(j*2*pi*d*(Nt-1)*sin(theta₁)/lambda)]；

where Nt is the total number of antenna elements in each antenna panel, d is the distance between the antennas, and lambda is the wavelength.

Similarly, the array response of the antenna panel L (2< ═ L) can be written as:

V_l＝[V_l(1),…V_l(Nt)]＝[1….exp(j*2*pi*d*(Nt-1)*sin(theta_l)/lambda)]。

thus, the array response (or transmit beam) of the antenna panel l can be written as a function of the array response of the antenna panel 1 and derived. From the array response of the antenna panel 1, the array response of the antenna panels 2,3, … L can be obtained.

It should be noted that the above equation is only a possible simple example, and the terminal may also use other methods to obtain the array response (transmission beam) of each antenna panel. The method for the UE to obtain the transmit beam of the antenna panel 2,3.. L based on the transmit beam indicated for the antenna panel 1 may be implemented by the terminal and is transparent to the network side device (the case of being opaque to the network side device is also applicable to the embodiment of the present invention).

As another embodiment, the network side device configures multiple sets of uplink reference signal resources for the terminal, and the terminal performs transmission beam scanning of the antenna panel by using the uplink reference signal resources (for example, the terminal uses one antenna panel to transmit one set of uplink reference signal resources, the uplink reference signal resources in the same group may use different uplink transmission beams, and the uplink reference signal resources in different groups use different antenna panels to transmit). The network side device indicates a preferred transmission beam for each group of uplink reference signal resources (for example, may be in the form of an uplink reference signal resource indication). The terminal may obtain the relative relationship between the transmission beams between different antenna panels according to the preferred transmission beams indicated by the network side device for each group.

In the above embodiment of the present invention, before step 41, the method further includes:

The network side equipment configures a first signal for the terminal, wherein the first signal can comprise a group of uplink reference signals. Without loss of generality, in the embodiment of the present invention, a description is made using an SRS (sounding reference signal) as an example of an uplink reference signal. Embodiments of the present invention use other types of reference signals as well. Each SRS is represented by one SRS resource, and a set of SRS resources may be defined as one set of SRS resources (SRS resources). The number of SRS resources contained in a first signal configured for the terminal by the network side equipment is greater than or equal to 1.

The network side device sends indication information about the configuration of the first signal, i.e. second indication information, to the terminal. After the terminal receives the second indication information, the configuration of the first signal can be obtained. And transmitting a first signal using the first antenna panel as indicated by the second indication information.

It should be noted that the terminal selecting which antenna panel to transmit the first signal may be implemented by the terminal and transparent to the base station (i.e., the base station does not know which antenna panel the terminal selects). Or, after selecting the antenna panel for transmitting the first signal, the terminal transmits indication information for indicating the antenna panel selected by the terminal to the network side device.

Different first uplink reference signal resources (i.e., SRS resources) in the first signal may be transmitted through the same or different transmission beams. The uplink transmission beam for transmitting one first uplink reference signal resource may be determined by the terminal, or may be determined by the network side device. If the uplink transmission beam for transmitting the first uplink reference signal resource is determined by the network side device, the network side device needs to transmit beam indication information of the first uplink reference signal resource to the terminal.

Preferably, in the above embodiment of the present invention, the first indication information includes: indication information of at least one uplink reference signal resource in first uplink reference signal resources corresponding to the first signal;

accordingly, step 42 includes:

In other words, the first indication information indicates the indication information of at least one preferred uplink reference signal resource selected by the network side device from the first signal (corresponding to a plurality of uplink reference signal resources), for example, the indicator SRI of the SRS resource.

Further, in the foregoing embodiment of the present invention, after step 43, the method further includes:

receiving third indication information sent by network side equipment, wherein the third indication information is used for indicating a terminal to send a second signal; the second signal includes one or more uplink signals to be transmitted. The second signal may be one or more sets of SRS resources.

Determining an antenna panel used to transmit the second signal;

and transmitting the second signal by using the transmission beam corresponding to the determined antenna panel on the determined antenna panel used for transmitting the second signal. The terminal transmits a second signal on some or all of the plurality of antenna panels.

Correspondingly, the method further comprises the following steps:

Preferably, when the second signal includes a plurality of signals, the reporting, to a network side device, beam indication information of a transmission beam of an antenna panel used by the terminal to transmit the second signal includes:

It should be noted that the beam indication information may be explicitly or implicitly notified.

In the above embodiments of the present invention, when the second signal is a plurality of reference signals, the beam indication information transmitted by the terminal is the beam indication information of the transmission beam corresponding to each reference signal.

For example, the second signal is a set of SRS resources, and the terminal may transmit one transmission beam indication information for each SRS resource. For another example, if the second signal is a plurality of SRS resource sets, the terminal may transmit one transmission beam indication information for each SRS resource set.

It should be noted that the determination of the transmission beams of the antenna panels other than the first antenna panel in step 43 is not necessarily the determination of the transmission beams of all the antenna panels, and may be the determination of the antenna panel used for transmitting the second signal by the terminal first, and then the determination of the transmission beams of only these antenna panels by the terminal.

It should be further noted that the third indication information may be a special indication information, or the first indication information may be included in the third indication information. For example, the third indication information is configuration information of the second signal, and the first indication information is included in the second indication information in the form of a higher layer parameter "spatialrelalationinfo" among RRC parameters configured for the second signal. For example, in the 3GPP system, the "spatialrelalationinfo" of an SRS Resource may be the SRS-spatialrelalationinfo parameter in the SRS-Resource parameter in the TS38.331 protocol. For example, in a 3GPP system, the "SpatialRelationInfo" of an SRS resource set for non-codebook uplink transmission (the parameter use in the higher layer parameter SRS-resource set of the SRS resource set is configured as 'non-codebook') may be CSI-RS resource indication information configured by the parameter associatedCSI-RS or the parameter CSI-RS in SRS-resource set.

As an example, the configuration information of the second signal may be contained in the third indication information; for example, if the second signal is a periodic SRS resource, and the network side device configures the periodic SRS resource for the terminal, the terminal periodically transmits the SRS resource. The configuration information of the second signal may not correspond to third indication information indicating that the terminal transmits the second signal; for example, the second signal is an aperiodic SRS resource, the network side device sends SRS resource configuration information to the terminal through RRC signaling, and triggers the terminal to send the second signal through SRS trigger signaling in the DCI, where the SRS trigger signaling corresponds to signaling (third indication information) instructing the terminal to send the second signal.

Preferably, the beam indication information of the transmission beam of the antenna panel includes at least one of the following information:

For example, for each antenna panel l, the terminal reports an index of an SRS resource with a transmission beam identical to that of the antenna panel l in an SRS resource set, where the SRS resource set is an SRS resource set transmitted by the terminal using the first antenna panel. Assume that a terminal transmits SRS resources through a first antenna panel using N beams, which may be denoted as [ V1, V2, … VN ]; assuming that the beam indicated by the network-side device for the first antenna panel is V1, the terminal determines that the uplink transmission beam of the antenna panel L (2< ═ L) is Vn, and 1< ═ N. The terminal may report [ n, l ] to the network side device, where n indicates the index of the determined beam (e.g., quantized with the set of beams on the first antenna panel), and l is the index of the antenna panel. In addition to the absolute beam index (e.g., SRS index), the terminal may further instruct the network side device to indicate one differential value of the transmission beam index indicated for the first antenna panel.

As another embodiment, the beam processing method further includes:

and reporting the beam indication information of the sending beams of the antenna panels except the first antenna panel determined by the terminal to network side equipment. Also, the beam indication information may be explicitly or implicitly notified.

Specifically, the beam indication information of the transmission beam of the antenna panel includes at least one of the following information:

a beam index of a transmit beam of the antenna panel;

Bearing in the above example, in the above embodiment of the present invention, when the second signal is a set of reference signal resources for CSI acquisition, the method further includes:

Or, in case that the second signal is a set of reference signal resources for CSI acquisition, the method further includes:

Specifically, the third signal is a physical uplink shared channel PUSCH. I.e. the terminal transmits a third signal on one or more antenna panels using the beam corresponding thereto.

For example, the terminal may transmit SRS for CSI acquisition on all antenna panels on the same time/frequency resource and then use all antenna panels simultaneously for data transmission of PUSCH. This approach is of the uplink MIMO (multiple input multiple output) type with joint transmission through all antenna panels.

For another example, the terminal transmits SRS for CSI acquisition on orthogonal time/frequency resources, and the base station selects an uplink antenna panel. Thereafter, the base station may schedule the terminal to transmit PUSCH on the antenna panel selected by the base station. This approach is an uplink MIMO type selected based on the antenna panel.

As an embodiment, the third signal is a physical uplink shared channel PUSCH, and the second signal is an SRS resource set obtained by CSI in a transmission mode corresponding to the PUSCH. The first indication information indicates spatialrelalationinfo of the SRS resource in the SRS resource set. The reference signal resource indication information of the second signal is SRS resource indication information SRI in UL grant DCI (carrying downlink control information of uplink grant), and is used for indicating SRS resources in an SRS resource set acquired from CSI in a transmission mode corresponding to PUSCH. For example, if the terminal is configured with parameter txConfig in the higher layer parameter PUSCH-Config as 'codebook' according to the 3GPP protocol, the reference signal resource indication information of the second signal is SRS resource indication information SRI in DCI, which is used to indicate SRS resources from the SRS resource set configured with usage in the higher layer parameter SRS-resources set.

In summary, in the embodiments of the present invention, the network side device indicates, to the terminal, the transmission beam corresponding to the first antenna panel of the terminal through the first indication information, and the terminal determines the transmission beams of other antenna panels according to the relative relationship between the transmission beams of the multiple antenna panels, so as to avoid transmitting a beam training signal on each antenna panel, and effectively reduce the overhead of an uplink signal; the measurement of the beam training signals on each antenna panel by the network side equipment is also avoided, and the processing complexity and time delay of the network side equipment are reduced; the network side equipment is further prevented from configuring the uplink wave beam of each antenna panel, and the configuration overhead of the uplink wave beam is reduced; and the terminal can be flexibly scheduled in uplink, and can respectively select transmitting beams for different antenna panels, thereby improving uplink transmission performance.

As shown in fig. 5, an embodiment of the present invention further provides a beam processing method, applied to a network side device, including:

step 51, sending first indication information to a terminal, where the first indication information is used to indicate a sending beam corresponding to a first antenna panel of the terminal. The terminal is a terminal comprising a plurality of antenna panels.

Optionally, the first indication information is sent through MAC-CE signaling.

The first indication information may directly indicate an index or a flag of the transmission beam of the first antenna panel, or may indirectly indicate the transmission beam of the first antenna panel by indicating an index or a flag of one of the resources (the resource has a correspondence relationship with the transmission beam).

For example, the base station configures a set of source SRS resources for the terminal to perform uplink CSI acquisition. The terminal transmits the set of source SRS resources using the first antenna panel. When the base station schedules the PUSCH signal, if one SRS resource (reference SRS resource) is indicated from the source SRS resource to the terminal by the SRS resource indication SRI for the terminal, it is equivalent to the base station indicating the transmission beam of the first antenna panel to the terminal as the transmission beam when the terminal transmits the reference SRS resource.

For another example, the base station configures a set of source SRS resources for the terminal to perform uplink CSI acquisition. The terminal transmits the set of source SRS resources using the first antenna panel. The base station transmits SRS resource indication information to the terminal, and the SRS resource indication information is used for indicating one SRS resource (reference SRS resource) from the source SRS resource to the terminal. And through the SRS resource indication information, the base station indicates the transmission beam of the first antenna panel to the terminal as the transmission beam when the terminal transmits the reference SRS resource.

the first indication information corresponds to SRS-SpatialRelationInfo, which takes as an example that SRS-SpatialRelationInfo indicates a source SRS resource. When the terminal needs to transmit the target signal corresponding to the target SRS resource, it needs to first determine the SRS signal corresponding to the source SRS resource, and transmit the target signal using the antenna panel corresponding to the SRS signal and the transmission beam on those antenna panels. That is, the base station indicates the first antenna panel and the transmission beam of the first antenna panel when transmitting the target SRS by indicating the source SRS resource.

Further, in the above embodiment of the present invention, the method further includes:

In this step, the terminal may derive the transmission beams of the lth antenna panel from the second and third antenna panels … … based on the relative relationship between the transmission beam of the first antenna panel and the transmission beams of the multiple antenna panels. L is an integer greater than or equal to 2, and preferably, L may be a quantity value of the antenna panels included in the terminal, and L may also be smaller than the quantity value of the antenna panels included in the terminal.

Further, the method further comprises:

Further, in the foregoing embodiment of the present invention, before step 51, the method further includes:

and determining the first indication information according to the first signal.

The network side equipment receives a first signal from a terminal and selects a preferred uplink reference signal resource (such as SRS resource) from the first signal. The selection of the uplink Reference Signal resource by the network side device may be based on some algorithms, for example, by sorting and selecting the received Signal qualities of different uplink Reference Signal resources, where the received Signal Quality may be RSRP (Reference Signal Receiving Power), RSRQ (Reference Signal Receiving Quality), or SINR (Signal to Interference plus noise ratio). The network side device may determine, by itself, a receive beam for receiving different uplink reference signal resources, for example, whether the receive beam is the same.

Preferably, the first indication information includes: and the network side equipment selects at least one uplink reference signal resource from the first uplink reference signal resources corresponding to the first signal.

The network side device sends the indication information (i.e. the first indication information) of the selected uplink reference signal resource to the terminal. For example, the network side device may send an index of the selected uplink reference signal resource in the reference signal resource set to the terminal. Through the first indication information, the terminal can acquire the uplink reference signal resource selected by the network side equipment. For another example, the first indication information indicates a form of a higher layer parameter "spatialrelalationinfo" in RRC parameters configured for the second signal (for example, the second signal is an SRS for CSI acquisition). And the subsequent terminal uses the transmission beam of the uplink reference signal resource selected by the network side equipment to transmit the uplink signal on the corresponding antenna panel.

As an embodiment, in the case that the configuration information of the first uplink reference signal resource corresponding to the first signal includes multiple sets of uplink reference signal resources,

Preferably, the sending the first indication information to the terminal includes:

transmitting configuration information of the second signal to the terminal; the configuration information of the second signal carries the first indication information. That is, the first indication information indicates the form of a higher layer parameter "spatialrelalationinfo" in RRC parameters configured for the second signal (for example, the second signal is an SRS for CSI acquisition).

As another embodiment, the method further comprises:

sending third indication information to the terminal, wherein the third indication information is used for indicating the terminal to send a second signal; the second signal includes one or more uplink signals to be transmitted.

Correspondingly, the method further comprises the following steps:
