Detailed Description

The technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the drawings in the embodiments of the present application, and it is obvious that the described embodiments are some, but not all, embodiments of the present application. All other embodiments obtained by a person of ordinary skill in the art based on the embodiments in the present application without making any creative effort belong to the protection scope of the present application.

The terms first, second and the like in the description and in the claims of the present application are used for distinguishing between similar elements and not necessarily for describing a particular sequential or chronological order. It is to be understood that the terms so used are interchangeable under appropriate circumstances such that the embodiments of the application are capable of operation in other sequences than those illustrated or otherwise described herein, and that the terms "first" and "second" used herein generally refer to a class and do not limit the number of objects, for example, a first object can be one or more. In addition, "and/or" in the specification and the claims means at least one of connected objects, and a character "/" generally means that a preceding and succeeding related objects are in an "or" relationship.

To facilitate understanding of the embodiments of the present application, the following is first explained.

1) Relating to multiple antennas

Wireless access technologies such as Long Term Evolution (LTE)/Long Term Evolution-Advanced (LTE-a) are constructed based on Multiple-Input Multiple-Output (MIMO) technology and Orthogonal Frequency Division Multiplexing (OFDM) technology. The MIMO technology can improve the peak rate and the system spectrum utilization by using the spatial degrees of freedom that can be obtained by the multi-antenna system.

In the process of standardization development, the dimension of the MIMO technology is continuously expanding. In LTE Rel-8, MIMO transmission of up to 4 layers can be supported. A Multi-User MIMO (MU-MIMO) technology is added in Rel-9, and a maximum of 4 downlink data layers can be supported in MU-MIMO transmission of TM (Transmission mode) -8. The transmission capability of Single-User MIMO (SU-MIMO) is extended to a maximum of 8 data layers in Rel-10.

The industry is further pushing MIMO technology towards three-dimensionality and large-scale. The third Generation Partnership Project (3 GPP) has completed a research Project for 3D channel modeling and is conducting research and standardization work for full-dimensional eFD-MIMO and New Radio (NR) MIMO. It is expected that in future 5G mobile communication systems, a larger scale, more antenna port MIMO technology will be introduced.

The large-scale massive MIMO technology uses a large-scale antenna array, can greatly improve the utilization efficiency of a system frequency band, and supports a larger number of access users. Therefore, the massive MIMO technology has been currently considered as one of the most potential physical layer technologies in the next generation mobile communication system.

In the massive MIMO technology, if a full digital array is adopted, the maximized spatial resolution and the optimal MU-MIMO performance can be achieved, but such a structure requires a large number of digital-to-analog/analog-to-digital (AD/DA) conversion devices and a large number of complete rf-baseband processing channels, which is a huge burden in terms of both equipment cost and baseband processing complexity.

In order to avoid the implementation cost and the equipment complexity, a digital-analog hybrid beamforming technology is developed, that is, on the basis of the conventional digital domain beamforming, a primary beamforming is added to a radio frequency signal near the front end of an antenna system. Analog forming enables a sending signal to be roughly matched with a channel in a simpler mode. The dimension of the equivalent channel formed after analog shaping is smaller than the actual number of antennas, so that the AD/DA conversion devices, the number of digital channels and the corresponding baseband processing complexity required thereafter can be greatly reduced. The residual interference of the analog forming part can be processed once again in the digital domain, thereby ensuring the quality of MU-MIMO transmission. Compared with full digital forming, digital-analog hybrid beam forming is a compromise scheme of performance and complexity, and has a high practical prospect in a system with a high frequency band and a large bandwidth or a large number of antennas.

2) With respect to the high frequency band

In the research on the next generation communication system after 4G, the working frequency band supported by the system is increased to above 6GHz, and reaches up to about 100 GHz. The high frequency band has richer idle frequency resources, and can provide higher throughput for data transmission. At present, 3GPP has completed high-frequency channel modeling work, the wavelength of a high-frequency signal is short, and compared with a low-frequency band, more antenna array elements can be arranged on a panel with the same size, and a beam with stronger directivity and narrower lobes is formed by using a beam forming technology. Therefore, the combination of a large-scale antenna and high-frequency communication is one of the trends in the future.

3) With respect to beam measurement (beam measurement) and beam reporting (beam reporting)

Analog beamforming is full bandwidth transmit and each polar array element on the panel of each high frequency antenna array can only transmit analog beams in a time division multiplexed manner. The shaping weight of the analog wave beam is realized by adjusting the parameters of the radio frequency front end phase shifter and other devices.

In a specific embodiment, a polling method is usually used to train an analog beamforming vector, that is, an array element in each polarization direction of each antenna panel sequentially sends training signals (i.e., candidate beamforming vectors) at an appointed time in a time division multiplexing manner, and a terminal feeds back a beam report after measurement, so that a network side device uses the training signals to implement analog beamforming transmission when transmitting a service next time. The contents of the beam report typically include the optimal number of beam identification information and the measured received power of each transmit beam.

When beam measurement is performed, the network side device configures report configuration Information, that is, configuration Information of a beam report, where Reference Signal resource setting (RS resource setting) is associated, where the RS resource setting includes at least one Reference Signal resource set (RS resource set), and each RS resource set includes at least one Reference Signal resource (RS resource), for example, a Synchronization Signal block (Synchronization Signal and PBCH block, SSB) resource or a Channel State Information Reference Signal (CSI-RS) resource. The terminal measures the Layer 1 Reference Signal received Power (L1-RSRP)/Layer 1 Signal to Interference plus Noise Ratio (L1-SINR) of each RS resource, and reports at least One optimal measurement result to the network side equipment. The reported content comprises a synchronization signal block resource indication SSBRI or a CSI-RS resource indication CRI and L1-RSRP/L1-SINR.

In the configuration information of the beam report, it is indicated whether the beam report is a packet-based beam report. If the non-packet based beam report is used, the terminal reports at least one optimal beam and the quality of the optimal beam, so that the network side device determines the beam used for transmitting the channel or the signal to the terminal. If the report is a packet-based beam report (packet-based beam report), the terminal reports a pair of beams and their qualities, and when the network-side device uses the pair of beams to send information to the terminal, the terminal can receive the information at the same time.

4) Regarding beam squint (beam squint)

When the bandwidth of a frequency band is large, beam squint occurs due to differences in signal propagation characteristics at different frequency locations. For example, a large bandwidth frequency band edge frequency point and a large bandwidth frequency band center frequency point have a deviation in a beam direction, and when a network performs beam training according to the center frequency point and selects an optimal beam, if the optimal beam is used for transmitting a channel in a full bandwidth, the beam direction at the edge frequency point may be deviated, and thus the quality of a beam link may be deteriorated.

Independent Beam Management (IBM)/Common Beam Management (CBM) was introduced in 3GPP to describe two different working modes under FR2 inter-band CA. The IBM means that the terminal UE manages independent beams, and the primary carrier (PCC) and the secondary carrier (SCC) may independently select an optimal beam. In this case, different Component Carriers (CCs) may have relatively optimal transceiving performance, but have disadvantages in that signaling overhead is large and the architecture design of the UE is more complicated. The CBM means that the UE performs a beam management process only by the PCC, and the SCC directly applies the configuration of the PCC. The method has the advantages of saving signaling overhead, simplifying the UE structure and reducing the cost. However, since FR2 adopts hybrid beamforming, such an arrangement method causes the beams of the PCC and the SCC to adopt the same phase shifter arrangement, so that the beam pointing direction of the SCC is deviated from the PCC to a certain extent, resulting in so-called "beam squint", and performance is degraded.

It is noted that the techniques described in the embodiments of the present application are not limited to Long Term Evolution (LTE)/LTE-Advanced (LTE-a) systems, but may also be used in other wireless communication systems, such as Code Division Multiple Access (CDMA), Time Division Multiple Access (TDMA), Frequency Division Multiple Access (FDMA), Orthogonal Frequency Division Multiple Access (OFDMA), Single-carrier Frequency Division Multiple Access (SC-FDMA), and other systems. The terms "system" and "network" in the embodiments of the present application are often used interchangeably, and the described techniques can be used for both the above-mentioned systems and radio technologies, as well as for other systems and radio technologies. The following description describes a New Radio (NR) system for purposes of example, and NR terminology is used in much of the description below, but the techniques may also be applied to applications other than NR system applications, such as generation 6 (6)^thGeneration, 6G) communication system.

Optionally, the beam information mentioned in the embodiment of the present application may also be referred to as: spatial relationship (spatial relationship) information, spatial domain reception filter (spatial domain reception filter) information, spatial domain Transmission filter (spatial domain Transmission filter) information, spatial filter (spatial filter), Transmission Configuration Indication (TCI) state (state) information, Quasi-co-located (QCL) information, or QCL parameters, etc. Here, the downlink beam information may be generally represented by TCI state information, QCL information, and the like. The uplink beam information can be generally expressed using spatial relationship information or TCI state information.

Optionally, the first object in the embodiment of the present application may include any one of: cell, subband, frequency band, component carrier CC, etc.

In order to solve the problem of how to avoid the performance reduction of a beam link caused by beam squint, in the embodiment of the application, a beam pairing technology is mainly introduced for large bandwidth or across frequency bands, and different transmitting beams are adopted at frequency point positions far away from each other through a reasonable beam measurement and reporting mechanism, and can be received at the same time of a terminal, so that the throughput is improved.

The beam measurement reporting method provided by the embodiment of the present application is described in detail below with reference to the accompanying drawings through specific embodiments and application scenarios thereof.

Referring to fig. 2, fig. 2 is a flowchart of a beam measurement reporting method according to an embodiment of the present application, where the method is executed by a terminal, and as shown in fig. 2, the method includes the following steps:

step 21: and sending the first beam report to the network side equipment.

In this embodiment, the first beam report may include beam identification information of a plurality of first objects. The beam identification information of at least two first objects corresponds to the same receiving beam information, and the receiving beam information is, for example, spatial domain receiving filter information of a terminal, spatial domain filter information of a terminal, or the like. The first object may comprise any one of: cell, sub-band, CC, etc. The beam identification information may be a reference signal resource indicator (resource indicator) such as SSBRI, CRI, etc.

For example, the first beam report includes beam identification information of multiple cells, or includes beam identification information of multiple subbands, or includes beam identification information of multiple frequency bands, or includes beam identification information of multiple CCs.

It should be noted that in the embodiment of the present application, a beam report (beam report) is reported, and the following takes SSBRI/CRI including a plurality of sub-bands as an example to explain the reason that the beam squint can be solved: because the analog beam is a weight value of beam forming determined by hardware such as a phase shifter, only one beam can be formed on one band at present; but when the band is too large, the use of the same transmit beam (Tx beam) and receive beam (Rx beam) for different sub-bands results in the beam link (beam link) performance being optimal at one sub-band, and the beam squint phenomenon occurs when applied to another sub-band, i.e. the beam link performance on another sub-band becomes poor; accordingly, the application proposes reporting SSBRI/CRI of multiple sub-bands, where the UE still uses a set of phase shifters to form a receive beam, that is, the Rx beam of the UE on the band is unchanged, but the Tx beam of the network is different in different sub-bands, such as Tx beam1 and Tx beam2, respectively, and both of them respectively form respective optimal links on two sub-bands for the same Rx beam of the UE, so reporting SSBRI/CRI of different sub-bands and corresponding to the same Rx beam to avoid beam squint.

According to the beam measurement reporting method, the terminal sends the first beam report to the network side device, the first beam report includes the beam identification information of the multiple first objects, so that the network side device can adopt different transmission beams at frequency point positions far away from each other, for example, different transmission beams are adopted on different cells/sub-bands/frequency bands/CCs, and can also keep the terminal receiving at the same time, thereby avoiding the performance reduction of a beam link caused by beam squint when the bandwidth is large or the frequency band is crossed, and improving the throughput.

In the embodiment of the present application, in order to solve the problem caused by beam squint, three beam measurement and reporting mechanisms are proposed, which are respectively described as follows.

Mechanism one

In this first mechanism, the terminal may receive the report configuration information from the network-side device before sending the first beam report to the network-side device. The report configuration information is, for example, CSI-ReportConfig. The report configuration information is 1 report configuration information, that is, the report configuration information includes configuration information of 1 beam report. The report configuration information may be characterized by at least one of:

(1) RS resource settings (RS resource setting) are included, and the RS resource settings are respectively on the plurality of first objects. That is, the reporting configuration information includes RS resource setting (or resource config) on a plurality of cells/subbands/bands/CCs.

Optionally, the RS resource setting may include a number or an identification ID of the first object, that is, a number of a cell/subband/band/CC, or an ID of a cell/subband/band/CC.

Alternatively, the RS resource setting may be configured in the configuration information of the first object, that is, in the cell configuration information, the subband configuration information, the band configuration information, or the CC configuration information.

(2) RS resource sets (RS resource sets) are included, and the RS resource sets are respectively on the plurality of first objects. That is, the reporting configuration information includes RS resource sets on a plurality of cells/subbands/bands/CCs.

Optionally, the RS resource set may include a number or an ID of the first object, that is, a number of a cell/subband/band/CC, or an ID of a cell/subband/band/CC.

Alternatively, the RS resource set may be configured in the configuration information of the first object, that is, in the cell configuration information, the subband configuration information, the frequency band configuration information, or the CC configuration information.

(3) RS resource groups are included, and the RS resource groups are respectively on the plurality of first objects. That is, the reporting configuration information includes RS resource groups on a plurality of cells/subbands/bands/CCs. At least 2 of these RS resource groups belong to one RS resource set. These RS resource groups include at least one RS resource in a set of RS resources.

Optionally, the RS resource group may include a number or an ID of the first object, that is, a number of a cell/subband/band/CC, or an ID of a cell/subband/band/CC.

Alternatively, the RS resource group may be configured in the configuration information of the first object, that is, in the cell configuration information, the subband configuration information, the frequency band configuration information, or the CC configuration information.

It can be understood that, after sending the report configuration information to the terminal, the network side device may send a Reference Signal (RS) according to the report configuration information, so that the terminal performs beam measurement. And the terminal may send a beam report to the network side device after performing the beam measurement.

Optionally, under the report configuration information, the type of the first beam report reported by the terminal may be a packet-based beam report (group based beam report).

The first beam report may include at least one of:

1) n sets of beam identification information.

The beam identification information is, for example, SSBRI, CRI, or the like. N is a positive integer. Each set of beam identification information includes M pieces of beam identification information, where M is the number of the plurality of first objects. For example, the report configuration information includes RS resource settings of 2 cells, and each set of beam identification information includes 2 pieces of beam identification information; or, the report configuration information includes RS resource settings of 3 cells, and each set of beam identification information includes 3 beam identification information.

Optionally, each set of beam identification information in the N sets of beam identification information corresponds to one piece of receiving beam information, that is, each set of beam identification information is paired, and each piece of receiving beam information corresponds to at least one set of beam identification information. The transmit beams corresponding to each set of beam identification information may be received simultaneously by their corresponding receive beam information.

Optionally, in the N sets of beam identification information, M beam identification information in each set of beam identification information respectively indicate RS resources in first information on different first objects, where the first information may include any one of the following: RS resource setting, RS resource collection and RS resource group. That is, the M pieces of beam identification information in each set of beam identification information respectively indicate RS resources in RS resource setting/RS resource set groups on different cells/subbands/frequency bands/CCs.

Optionally, the above N groups of beam identification information satisfy at least one of the following characteristics:

arranging the beam identification information included in each group of beam identification information according to a preset sequence;

arranging N groups of beam identification information according to a preset sequence, determining which beam identification information is a group according to the preset sequence, and pairing the beam identification information, wherein the pairing means that the beam identification information corresponds to the same Rx beam;

arranging the beam identification information included in the N groups of beam identification information according to a preset sequence.

For example, a first beam report reported by the UE0 includes 3 groups of beam identification information, where the first group of beam identification information includes the CRI1 of the cell1 and the CRI2 of the cell2, the second group of beam identification information includes the CRI3 of the cell1 and the CRI4 of the cell2, and the third group of beam identification information includes the CRI5 of the cell1 and the CRI6 of the cell 2; then:

if the sequence is arranged according to the characteristic (i), the preset sequence is as follows: and sequencing according to the cell number, then: in the 3 groups of beam identification information, the reporting sequence of the first group of beam identification information is as follows: the reporting sequence of the CRI1 and the CRI2 and the second group of beam identification information is as follows: CRI3, CRI4, and the reporting sequence of the third group of beam identification information is: CRI5, CRI 6; or, the reporting sequence of the first group of beam identifier information is: the reporting sequence of the CRI2 and the CRI1 and the second group of beam identification information is as follows: CRI4, CRI3, and the reporting sequence of the third group of beam identification information is as follows: CRI6, CRI 5;

if the arrangement is carried out according to the second characteristic, the preset sequence is as follows: in the sequential order of the groups, then: in the 3 groups of beam identification information, first group of beam identification information is arranged, then second group of beam identification information is arranged, and finally third group of beam identification information is arranged, and the corresponding reported beam identification information is: CRI1, CRI2, CRI3, CRI4, CRI5, CRI 6;

if the data are arranged according to the characteristics of the third step, the preset sequence is as follows: and sequencing according to the cell numbers, wherein the CRIs are matched in the same order in all CRIs of each cell, and then: in the above 3 groups of beam identification information, the CRI1, the CRI3, and the CRI5 of the cell1 are arranged first, and then the CRI2, the CRI4, and the CRI6 of the cell2 are arranged second, in which the paired CRI1 and the CRI2 are arranged first in all CRIs of the cell1 and the cell2 respectively, the paired CRI3 and the CRI4 are arranged second in all CRIs of the cell1 and the cell2 respectively, and the paired CRI5 and the CRI6 are arranged third in all CRIs of the cell1 and the cell2 respectively, that is, the corresponding reported beam identification information is: CRI1, CRI3, CRI5, CRI2, CRI4, CRI 6.

2) Each beam identifies the quality of the beam link to which the information corresponds.

For example, the beam link quality is L1-RSRP, L1-SINR, and/or throughput of the corresponding beam link, so that the network side device determines the optimal beam link. The reporting order for the beam link quality may be the same as the order of the corresponding beam identification information.

3) The sum of the beam link quality corresponding to each group of beam identification information, or the weighted average of the beam link quality corresponding to each group of beam identification information.

For example, the weighted average/total L1-RSRP, L1-SINR, throughput, and/or the like of the beam link corresponding to each group of beam identification information are reported, so that the network side device determines the optimal beam link. The reporting order of the sum of the beam link quality or the weighted average may be the same as the order of the corresponding beam identification information groups.

4) And the first identification ID corresponds to each group of beam identification information. The first identifier may be configured to identify the reception beam information corresponding to each group of beam identification information.

Optionally, for the content in the first beam report, at least one of the following characteristics may be satisfied:

information transmitted by a first transmit beam is simultaneously received by the terminals; wherein the first transmit beam is of a plurality of the first objects, the first transmit beam being characterized by beam identification information belonging to the same group;

each group of beam identification information corresponds to one piece of receiving beam information of the terminal;

each piece of receiving beam information of the terminal corresponds to at least one group of beam identification information;

each beam identification information in each group of beam identification information corresponds to different first objects;

determining that the information on the transmitting beams represented by the beam identification information belonging to the same group is received simultaneously according to the first identification corresponding to each group of beam identification information;

and determining that the information on the transmitting beams represented by the beam identification information belonging to the same group is simultaneously received according to the preset arrangement sequence of the beam identification information of each group.

In this way, with the first beam report satisfying the above characteristics, the network side device can use different transmission beams at frequency point positions far away from each other, such as different cells/subbands/bands/CCs, and can also maintain simultaneous reception of the terminals.

Optionally, after sending the first beam report to the network side device, the terminal may further receive beam indication information from the network side device, and transmit a channel or a reference signal on a corresponding beam link according to the beam indication information. Wherein, the source RSs of the TCI states in the beam indication information may be: all or part of RS resources corresponding to the group of beam identification information; or, the plurality of source RSs of one TCI state in the beam indication information may be: and all or part of RS resources corresponding to the group of beam identification information. In this way, the terminal can use one receiving beam to realize the simultaneous beam forming of a beam link with the transmitting beam of the network side device on a plurality of cells/subbands/bands/CCs, thereby ensuring the maximum throughput of information transmission.

That is, after receiving the first beam report, the network side device may perform beam indication according to the first beam report when scheduling channel transmission or reference signal transmission, such as scheduling target channel/reference signal is simultaneously transmitted on multiple cells/subbands/frequency bands/CCs, and use all or part of RS resources corresponding to a group of beam identification information as source RSs of multiple TCI states in the beam indication of the target channel/reference signal, or use all or part of RS resources corresponding to a group of beam identification information as multiple source RSs in one TCI state in the beam indication of the target channel/reference signal.

In an optional implementation manner, the network side device may update beam information (e.g., TCI state) on multiple cells/subbands/bands/CCs. When the beam indication information received by the terminal includes multiple TCI states, the multiple TCI states may have the same TCI state identity, and/or the multiple TCI states may belong to different TCI state pools. For example, the TCI states have the same TCI state identification but belong to different TCI state pool. When the network updates the TCI state ID, the TCI state with the same TCI state ID on a plurality of cells/sub-bands/frequency bands/CCs is updated together. For another example, when the network updates the TCI state on one cell/subband/band/CC, the TCI state ID of the updated TCI state is also used for other cells/subbands/bands/CCs.

In an optional embodiment, the first beam report reported by the UE1 includes the following contents:

{CRI1 on cell1,CRI2 on cell2}for Rx beam1，

{CRI3 on cell1,CRI4 on cell2}for Rx beam1，

{CRI5 on cell1,CRI6 on cell2}for Rx beam2，

……

as can be seen from the above, the first beam report reported by the UE1 includes multiple sets of beam identification information (CRI), and the CRI in each set correspond to 2 cells respectively and can be paired (pairing means using one Rx beam). For example, Rx beam1 corresponds to two beam information of CRI1 of cell1 and CRI2 of cell2, Rx beam1 corresponds to two beam information of CRI3 of cell1 and CRI4 of cell2, Rx beam2 corresponds to two beam information of CRI5 of cell1 and CRI6 of cell2, and so on. Also, CRI1/3/5 corresponds to CSI-RS resource in resource setting of cell1, and CRI2/4/6 corresponds to CSI-RS resource in resource setting of cell 2.

Optionally, in the first beam report reported by the UE1, for each group of CRI, an ID indication may be explicitly added, or implicitly indicated according to a preset permutation order: every adjacent 2 CRI pairs, namely the first two CRIs are one group and correspond to one Rx beam, the next two CRIs are one group and also correspond to one Rx beam, and so on; alternatively, the first half of the CRI and the second half of the CRI are paired one by one in order corresponding to cell1 and cell 2.

Mechanism two

In the second mechanism, before the first beam report is sent to the network side device, the terminal may receive a plurality of report configuration information from the network side device, that is, the configuration information received by the terminal from the network side device includes a plurality of report configuration information. The report configuration information is, for example, CSI-ReportConfig.

Optionally, each report configuration information may have at least one of the following characteristics:

(1) each reporting configuration information corresponds to one first object, that is, each reporting configuration information corresponds to one cell/subband/band/CC.

In this (1), each report configuration information may be configured in the configuration information of the first object, that is, in the cell configuration information, the subband configuration information, the band configuration information, or the CC configuration information. Alternatively, each report configuration information may include a number or ID of the first object, that is, a number or ID of a cell/subband/band/CC.

(2) Each report configuration information includes: an RS resource setting or set of RS resources corresponding to the same first object as the reporting configuration information. If each report configuration information includes: RS resource setting or RS resource set of the same cell/subband/band/CC corresponds to the report configuration information.

It can be understood that, after the network side device sends the multiple pieces of reporting configuration information to the terminal, the network side device may send the RS according to the multiple pieces of reporting configuration information, so that the terminal performs beam measurement. And the terminal can send the beam report to the network side device after the beam measurement is carried out.

Optionally, under the multiple pieces of report configuration information, the type of the first beam report reported by the terminal may be a non-group based beam report (non-group based beam report).

The first beam report comprises a plurality of beam reports, each beam report may comprise at least one of:

1) p beam identification information.

The beam identification information is SSBRI, CRI, or the like. P is a positive integer. Each beam identification information corresponds to one piece of receiving beam information, and each piece of receiving beam information corresponds to at least one piece of beam identification information.

Optionally, in the P pieces of beam identification information, the beam identification information is arranged according to a preset sequence, so as to determine the beam identification information corresponding to the same Rx beam in different beam reports according to the preset sequence. For example, if the terminal reports beam report 1 and beam report 2, the CRI1 of the cell1 and the CRI2 of the cell2 correspond to the same Rx beam1, the CRI3 of the cell1 and the CRI4 of the cell2 correspond to the same Rx beam2, and the preset sequence is as follows: the pairing CRI are in the same order in the respective beam reports, then: in beam report 1, the CRI1 of cell1 is ranked first, and then the CRI3 of cell1 is ranked; in beam report 2, the CRI2 of cell2 is ranked first, and then the CRI4 of cell2 is ranked.

For example, the beam link quality is L1-RSRP, L1-SINR, and/or throughput of the corresponding beam link. The reporting order for the beam link quality may be the same as the order of the corresponding beam identification information.

3) And a second identifier corresponding to each beam identifier information. The second identifier may be configured to identify the receiving beam information corresponding to each beam identification information.

Optionally, for the content of different beam reports in the multiple beam reports, at least one of the following characteristics may be satisfied:

the information transmitted by the second transmit beam is received simultaneously by the terminal; wherein the second transmit beam is of a plurality of the first objects, the second transmit beam being characterized by beam identification information corresponding to the same receive beam information in each beam report;

each beam identification information corresponds to one receiving beam information of the terminal;

each piece of receiving beam information of the terminal corresponds to at least one piece of beam identification information;

determining that the information on the transmitting beams represented by the beam identification information in different beam reports is received simultaneously according to the second identification corresponding to the beam identification information;

and determining that the information on the transmitting beams represented by the beam identification information in different beam reports is received simultaneously according to the preset arrangement sequence of the beam identification information.

In this way, by means of multiple beam reports satisfying the above characteristics, the network side device can use different transmission beams at frequency point positions far away from each other, for example, different transmission beams on different cells/subbands/frequency bands/CCs, and can also keep the terminal receiving at the same time.

Optionally, after sending the first beam report to the network side device, the terminal may further receive beam indication information from the network side device, and transmit a channel or a reference signal on a corresponding beam link according to the beam indication information. Wherein, the source RSs of the TCI states in the beam indication information may be: all or part of RS resources corresponding to the beam identification information corresponding to the same receiving beam information in different beam reports; or, the multiple source RSs of one TCI state in the beam indication information may be: all or part of RS resources corresponding to the beam identification information corresponding to the same receiving beam information in different beam reports. In this way, the terminal can use one receiving beam to realize a beam forming link with the transmitting beam of the network side equipment on a plurality of cells/subbands/frequency bands/CCs, thereby ensuring that the throughput of information transmission is maximized.

That is, after receiving the first beam report, the network side device may perform beam indication according to the first beam report when scheduling channel transmission or reference signal transmission, such as when a scheduling target channel/reference signal is simultaneously transmitted on multiple cells/subbands/frequency bands/CCs, and use all or part of RS resources corresponding to beam identification information corresponding to the same received beam information in different beam reports as source RSs of multiple TCI states in the beam indication; or, all or part of RS resources corresponding to the beam identification information corresponding to the same receiving beam information in different beam reports are used as the multiple source RSs of one TCI state in the beam indication.

In an optional implementation manner, the network side device may update beam information (e.g., TCI state) on multiple cells/subbands/bands/CCs. When the beam indication information received by the terminal includes multiple TCI states, the multiple TCI states may have the same TCI state identity, and/or the multiple TCI states may belong to different TCI state pools. For example, the multiple TCI states have the same TCI state identity, but belong to different TCI state pools. When the network updates the TCI state ID, the TCI state with the same TCI state ID on a plurality of cells/sub-bands/frequency bands/CCs is updated together. For another example, when the network updates the TCI state on one cell/subband/band/CC, the TCI state ID of the updated TCI state is also used for other cells/subbands/bands/CCs.

In an optional embodiment, the first mechanism and the second mechanism may be combined, for example, first perform beam measurement and report based on the first mechanism, and perform beam measurement and report again based on the second mechanism on a beam corresponding to the reported beam identification information according to the beam report content in the first mechanism; otherwise, the same principle is applied.

Mechanism III

In the third mechanism, the terminal may receive the report configuration information from the network-side device before transmitting the first beam report to the network-side device. The report configuration information is, for example, CSI-ReportConfig. The report configuration information is 1 report configuration information, that is, the report configuration information includes configuration information of 1 beam report. The report configuration information may be characterized by at least one of:

each RS resource setting associated with the beam report corresponds to a plurality of first objects; that is, each RS resource setting associated with the beam report corresponds to multiple cells/subbands/bands/CCs;

each RS resource set associated with the beam report corresponds to a plurality of first objects; that is, each RS resource set associated with the beam report corresponds to multiple cells/subbands/bands/CCs;

RS resource in each RS resource setting associated with the beam report has a plurality of TCI states;

the RS resource in each RS resource set associated with a beam report has multiple TCI states.

It can be understood that, after the network side device sends the report configuration information to the terminal, the network side device may send the RS according to the report configuration information, so that the terminal performs beam measurement. And the terminal may send a beam report to the network side device after performing the beam measurement. In this embodiment, when the network side device sends an RS on each cell/subband/band/CC, different TCI states may be used. That is, the RS resource has a plurality of TCI states, where each TCI state corresponds to one cell/subband/band/CC.

Optionally, under the report configuration information, the first beam report reported by the terminal may include at least one of the following:

1) k beam identification information. Wherein K is a positive integer.

2) And the RS resource corresponding to each beam identification information measures the beam link quality when each TCI state in a plurality of TCI states is used. The reporting order of the beam link quality may be the same as the order of the corresponding TCI state.

3) The sum of the beam link quality measured when multiple TCI states are used by the RS resource corresponding to each beam identification information.

4) And weighted average of the beam link quality measured when multiple TCI states are used by the RS resource corresponding to each beam identification information.

For example, the network side device determines the transmission beam of the CSI-RS resource on subband 1 using the first TCI state of the CSI-RS resource or the first source RS of the TCI state, and determines the transmission beam of the CSI-RS resource on subband 2 using the second TCI state of the CSI-RS resource or the second source RS of the TCI state. When a certain sub-band transmits the CSI-RS, the network side equipment only transmits the part of the CSI-RS resource on the sub-band, and the part on the other sub-band can be left alone or set to zero. And the UE simultaneously receives the CSI-RS on the two transmitting beams by using the same receiving beam to obtain the beam link quality of the CSI-RS resource on the two sub-bands. After a plurality of CSI-RS resources are measured, the beam identification information to be reported may be determined according to the beam link quality of each CSI-RS resource on each subband, or the sum of the beam link qualities on each subband, or the weighted average of the beam link qualities on each subband.

Optionally, after sending the first beam report to the network side device, the terminal may further receive beam indication information from the network side device, and transmit a channel or a reference signal on a corresponding beam link according to the beam indication information. Wherein, the source RS of the TCI state in the beam indication information is: and one beam identification information corresponds to the RS resource. In this way, the terminal can use one receiving beam to realize a beam forming link with the transmitting beam of the network side equipment on a plurality of cells/subbands/frequency bands/CCs, thereby ensuring that the throughput of information transmission is maximized.

That is, after receiving the first beam report, the network side device may perform beam indication according to the first beam report when scheduling channel transmission or reference signal transmission, for example, scheduling target channel/reference signal is simultaneously transmitted on multiple cells/subbands/frequency bands/CCs, and use RS resource corresponding to one beam identification information as source RS of TCI state in the beam indication.

In this embodiment, for the beam link quality in the beam report, a differential reporting manner may be used, for example, a differential manner is used for the beam link quality on the same cell/subband/frequency band/CC, or a differential manner is used for the beam link quality on multiple cells/subbands/frequency bands/CCs, and the like. The difference mode is as follows: reporting the absolute value of the link quality of one beam, and then reporting the relative values of the link qualities of other beams relative to the link quality of the beam.

Optionally, when the first beam report reported by the terminal includes the quality of multiple beam links, the quality of the multiple beam links may be reported in a differential manner. For example, the first beam report includes: an absolute value of a first beam link quality of the plurality of beam link qualities, and a relative value of other beam link qualities of the plurality of beam link qualities other than the first beam link quality with respect to the first beam link quality.

Optionally, the form of reporting the beam link quality in the first beam report in a differential manner may include at least one of the following:

when the first beam report comprises a plurality of groups of beam identification information, reporting the quality of a plurality of beam links corresponding to each group of beam identification information by using a differential mode;

when the first beam report comprises a plurality of groups of beam identification information, reporting the quality of a plurality of beam links corresponding to the plurality of groups of beam identification information by using a differential mode;

when the first beam report comprises a plurality of groups of beam identification information, reporting the quality of a plurality of beam links corresponding to the same receiving beam information by using a differential mode;

when the first beam report comprises a plurality of beam reports, reporting the link quality of a plurality of beams in each beam report in a differential mode;

the RS resource corresponding to each beam identification information in the first beam report reports the beam link quality measured when each TCI state in a plurality of TCI states is used in a differential mode;

the RS resource corresponding to the same beam identification information in the first beam report reports the beam link quality measured when a plurality of TCI states are used in a differential mode;

reporting the quality of a plurality of beam links corresponding to the same first object in the first beam report by using a differential mode;

the quality of the plurality of beam links corresponding to the plurality of first objects in the first beam report is reported using a differential manner.
