Description

Quasi co-location relation indicating method, device and storage medium

Technical Field

The present application relates to communications technologies, and in particular, to a method, an apparatus, and a storage medium for indicating a quasi co-located relationship.

Background

In the New air interface (NR) of 5G, a transmission configuration indicator (Transmission Configuration Indicator, TCI) is added to indicate a Quasi Co-Location relationship (QCL) between a demodulation signal of a data or control channel and one or more reference signals.

The 5G protocol specifies multiple types of quasi co-sited relationships, each representing a different channel parameter type. For example, if the quasi co-located type used is type-D, it indicates that one data or control channel and another reference signal are transmitted using the same beam. In order to implement the quasi co-sited configuration of different channels, in some implementations it is necessary to configure the TCI list in configuration parameters of different channels, which not only increases redundancy of information configuration, but also increases complexity of indication configuration.

The foregoing description is provided for general background information and does not necessarily constitute prior art.

Although the LTE system is described above as an example, it should be understood by those skilled in the art that the present application is not limited to LTE systems, but may be applied to other wireless communication systems, such as GSM, CDMA2000, WCDMA, TD-SCDMA, and future new network systems.

Based on the above-mentioned mobile terminal hardware structure and communication network system, various embodiments of the present application are presented.

First, an application scenario applicable to the present application will be described.

Fig. 3 is a schematic view of an application scenario provided in an embodiment of the present application. Referring to fig. 3, wireless communication is possible between a network device 301 and a terminal device 302, so as to implement data transmission. Alternatively, the terminal device 302 may be the mobile terminal in fig. 1 or the UE in fig. 2; the network device 301 may be other devices than the UE in fig. 2, such as a base station eNodeB.

The technical scheme of the embodiment of the application can be applied to NR communication technology, wherein NR refers to new generation wireless access network technology, and can be applied to future evolution networks such as a fifth generation mobile communication (the 5th Generation Mobile Communication,5G) system. The scheme in the embodiment of the application can be also applied to other wireless communication networks such as wireless fidelity (Wireless Fidelity, WIFI), long-term evolution (Long Term Evolution, LTE) and the like, and the corresponding names can be replaced by the names of the corresponding functions in the other wireless communication networks.

The network architecture and the service scenario described in the embodiments of the present application are for more clearly describing the technical solution of the embodiments of the present application, and do not constitute a limitation on the technical solution provided by the embodiments of the present application, and those skilled in the art can know that, with the evolution of the network architecture and the appearance of the new service scenario, the technical solution provided by the embodiments of the present application is applicable to similar technical problems.

In 5G communication, since a beam-based transmission method is required, a TCI architecture is added, and the TCI indicates a quasi co-location relationship between data and a reference signal.

Alternatively, the reference signal may include SSB (Synchronization Signal and PBCH block ) or the like composed of synchronization signal (Synchronization Signal, SS) and physical broadcast channel (Physical Broadcasting Channel, PBCH) together. Alternatively, the synchronization signals may include a primary synchronization signal (Primary Synchronization Signal, PSS), a secondary synchronization signal (Secondary Synchronization Signal, SSS), and the like.

The quasi-co-location relationship includes a plurality of types, and can be specifically classified into four types of Type-a QCL, type-B QCL, type-C QCL, and Type-D QCL, for representing different combinations or selections of Doppler Shift (Doppler Shift), doppler Spread (Doppler Spread), average Delay time (Average Delay), delay Spread (Delay Spread), and spatial receive beam parameters (Spatial Rx Parameter).

Optionally, the Type-D quasi co-location indicates that the data can be transmitted by using the same beam as the reference signal, and the receiving end can use a corresponding receiving filter. Accordingly, the beam pairing relationship corresponding to the data and reference signals may be indicated by configuring the TCI.

In some techniques, a physical downlink control channel (Physical Downlink Control Channel, PDCCH), a physical downlink shared channel (Physical Downlink Share Channel, PDSCH), a physical uplink control channel (Physical Uplink Control Channel, PUCCH), a physical uplink shared channel (Physical Uplink Share Channel, PUSCH), and a TCI state list (TCI-state list) for indicating QCI are respectively used in a PDCCH configuration (PDCCH-configuration), a PDSCH configuration (PDSCH-configuration), a PUCCH configuration (PUCCH-configuration), a PUSCH configuration (PUSCH-configuration), respectively. The TCI state may be configured for PDCCH, PDSCH, PUCCH, PUSCH, etc. by higher layer signaling.

Fig. 4 is a schematic diagram of a quasi co-location of a channel and a reference signal according to an embodiment of the present application. As shown in fig. 4, taking the quasi co-location of the PDCCH, PDSCH and reference signals as an example, the PDCCH configuration and PDSCH configuration may each include a TCI status list. Optionally, a plurality of TCI status IDs in PDCCH configuration: ni, nj, nk, mapped to TCI state ID in PDSCH configuration: ni, nj, nk, and have correspondence with a plurality of reference signals Si, sj, sk.

As shown, ni corresponds to quasi-co-location with reference signal Si, nj corresponds to quasi-co-location with reference signal Sj, nk corresponds to quasi-co-location with reference signal Sk. It is possible to indicate which TCI state ID to use, i.e. quasi co-located with which reference signal, by higher layer configuration. When the PDCCH or PDSCH is indicated to be quasi co-located with any reference signal, the PDCCH or PDSCH can be transmitted through the wave beam corresponding to the reference signal.

For example, when PDCCH or PDSCH is indicated to be quasi co-located with reference signal Si, then transmission of PDCCH or PDSCH may be performed using a beam corresponding to reference signal Si.

In the above design, the TCI status lists of different channels are configured in respective configuration parameters, and when the TCI status list changes, each channel needs to change configuration, which increases the complexity of indicating configuration in the beam management process, so that the system efficiency is low. Therefore, to simplify the beam management flow, a TCI architecture is designed to uniformly manage TCI indications of all channels.

In view of this, an embodiment of the present application provides a quasi co-location relationship indicating method, which can determine a unified TCI pool according to a beam set of an uplink reference signal and/or a downlink reference signal, and indicate a quasi co-location relationship according to the TCI pool, without configuring a corresponding TCI status list in each channel, thereby simplifying configuration complexity and improving system efficiency.

The following describes embodiments of the present application and how the technical solutions of the present application solve the above technical problems in detail. The following embodiments may be combined with each other, and the same or similar concepts or processes may not be described in detail in some embodiments. Embodiments of the present application will be described below with reference to the accompanying drawings.

Fig. 5 is a flowchart of a quasi co-location relationship indication method according to an embodiment of the present application. The main implementation body of the method in this embodiment may be a network device. As shown in fig. 5, the method may include:

step 501, determining a TCI pool according to a beam set of an uplink reference signal and/or a downlink reference signal.

Alternatively, the TCI pool may be referred to as TCI Configure Pool, and is used to store the beam set corresponding to the reference signal. The reference signals may include uplink reference signals and/or downlink reference signals.

The uplink in the embodiment of the present application may refer to that the terminal device sends to the network device, and the downlink may refer to that the network device sends to the terminal device. Correspondingly, the uplink reference signal may refer to a reference signal sent by the terminal device to the network device, and the downlink reference signal may refer to a reference signal sent by the network device to the terminal device.

The transmission and reception of signals may be implemented on a beam basis. Different reference signals may be transmitted based on different beams, and when there are multiple reference signals, the beams corresponding to the multiple reference signals may form a beam set from which the TCI pool may be determined.

Optionally, the TCI pool may include a beam set of at least one uplink reference signal, or may include a beam set of at least one downlink reference signal, or may also include a beam set of at least one uplink reference signal and a beam set of at least one downlink reference signal.

Step 502, according to the TCI pool, TCI indication information is sent, where the TCI indication information is used to indicate a quasi co-location relationship between data and reference signals.

Optionally, the data may include uplink data and/or downlink data. Alternatively, the uplink data may be data sent by the terminal device to the network device, and the downlink data may be data sent by the network device to the terminal device.

Alternatively, the uplink data may include at least one of PUCCH and PUSCH, and the downlink data may include at least one of PDCCH and PDSCH. Based on this, the TCI indication information may be used to indicate a quasi co-sited relationship of at least one of PUCCH, PUSCH, PDCCH and PDSCH with a reference signal.

In practical application, a TCI pool may be configured at the network device side, where a beam set corresponding to a reference signal is stored in the TCI pool, when a quasi co-location relationship is needed to be used, an appropriate beam may be selected from the TCI pool, a corresponding reference signal may be determined according to the selected beam, and then TCI indication information is sent to indicate that the data may be quasi co-located with the reference signal, so that the terminal device may determine which beam corresponding to the reference signal is used to receive or send the data according to the quasi co-location relationship indicated by the TCI indication information.

Therefore, the indication of the quasi co-location relationship can be realized by adding TCI indication information to the TCI pool, a TCI state list is not required to be configured in each channel, and when the beam set is changed, the TCI pool is directly modified, and the configuration of each channel is not required to be modified respectively.

According to the quasi co-location relation indicating method provided by the embodiment, the TCI pool can be determined according to the beam set of the uplink reference signal and/or the downlink reference signal, and the TCI indicating information is sent according to the TCI pool and used for indicating the quasi co-location relation of data and the reference signal, so that the quasi co-location relation is indicated quickly and accurately in a mode of adding the TCI indicating information to the TCI pool, TCI lists are not required to be configured in each channel, redundancy and complexity of information configuration are effectively reduced, and system efficiency is improved.

In the embodiment of the application, the TCI pool can be determined according to the beam set of the uplink reference signal and/or the downlink reference signal. Optionally, the beam set of the uplink reference signal may include all uplink transmission beams and/or uplink reception beams during beam scanning; the beam set of the downlink reference signals may include all downlink transmit beams and/or downlink receive beams during beam scanning.

For example, the beam set of the uplink reference signal may include all uplink transmission beams during beam scanning, or may include all uplink reception beams during beam scanning, or may include all uplink transmission beams and all downlink transmission beams during beam scanning. The beam set of the downlink reference signal may include all downlink transmission beams during beam scanning, or may include all downlink reception beams during beam scanning, or may include all downlink transmission beams and all downlink transmission beams during beam scanning. Thereby taking into account all transmit and/or receive beams as they are scanned and expanding the range of quasi co-sited relationships.

Optionally, determining the TCI pool according to the beam set of the uplink reference signal and/or the downlink reference signal may include: and determining a TCI pool according to all pairs of transmitting beams and receiving beams in the beam set of the uplink reference signal and/or the downlink reference signal. After the TCI pool is determined through the pairing of the beams, the reference signals in the quasi co-location relationship can be rapidly and accurately determined through the TCI pool, and the processing efficiency and the accuracy of the quasi co-location relationship are improved.

In practical applications, the TCI pool may be determined according to the beam set of the uplink reference signal and the beam set of the downlink reference signal, or may be determined according to the beam set of the uplink reference signal alone, or according to the beam set of the downlink reference signal alone. The following description will be given respectively.

In a first alternative implementation, the TCI pool may be determined according to a beam set of an uplink reference signal and a beam set of a downlink reference signal, where the beam set of the uplink reference signal may include all uplink transmit beams and all uplink receive beams during beam scanning, and the beam set of the downlink reference signal may include all downlink transmit beams and all downlink receive beams during beam scanning.

Fig. 6 is a schematic beam diagram of a network device and a terminal device according to an embodiment of the present application. As shown in fig. 6, the network device side has beams #1 to #8, and of course, the network device side may form beams with different widths according to specific situations; the terminal device side has beams 1 to 4, and the terminal device side may form beams with different widths according to specific situations. In beam scanning, reference signals may be transmitted and received based on the beams shown in the figures.

The uplink reference signal may be transmitted by any beam at the terminal device side and received by any beam at the network device side, and the downlink reference signal may be transmitted by any beam at the network device side and received by any beam at the terminal device side.

In the beam-based communication system, the terminal device can feed back the measurement results of each downlink beam to the network device, and the network device side can also have the measurement results of each uplink beam, so that the network device side has the capability of knowing the pairing information of all beams.

Optionally, in the access process, the terminal device side may measure the quality of each transmitting beam at the network device side, so as to obtain and feed back a measurement result, and the network device side may measure the quality of each transmitting beam at the terminal device side, so as to obtain a corresponding measurement result.

Optionally, the TCI pool may be determined according to all pairs of the transmit beam and the receive beam in the beam set of the uplink reference signal and the downlink reference signal, so as to improve applicability of the quasi co-sited relationship.

When determining the TCI pool according to all pairs of the transmit beam and the receive beam in the beam set of the uplink reference signal and the downlink reference signal, all beam pairing manners may be traversed to obtain a corresponding TCI pool, for example, table 1.

Table 1 an example of a TCI pool provided by an embodiment of the present application

As shown in table 1, the network device side may configure all connection beams as one TCI pool. In downlink, the network device may use beams #1 to #8 as transmit beams, and the terminal device may use beams 1 to 4 as receive beams; on the uplink, the terminal device may use beams 1 to 4 as transmit beams, and the network device may use beams #1 to #8 as receive beams.

Different reference signals may correspond to different transmit and receive beams. For example, in the uplink reference signal, the reference signal 1 is transmitted by using a terminal equipment side beam x 1, and the network equipment side beam #1 is received; the reference signal 2 is transmitted by using a terminal equipment side beam x 1, and a network equipment side beam #2 is received; and so on, when the beam scans, all uplink pairing modes are traversed, and 4×8=32 uplink reference signals can be used for transmission by using different network device side beams and/or terminal device side beams respectively.

Similarly, among the downlink reference signals, the reference signal 33 is transmitted using the network device side beam #1, and the terminal device side beam 1 is received; the reference signal 34 is transmitted using the network device side beam #1 and the terminal device side beam x 2 is received; and so on, when the beam scans, all downlink pairing modes are traversed, and 8×4=32 downlink reference signals can be transmitted by using different network device side beams and/or terminal device side beams respectively.

As shown in table 1, any one network device side beam and any one terminal device side beam constitute one beam pair, and 8 beams on the network device side and 4 beams on the terminal device side may have 2×8×4=64 beam pairs in total.

Optionally, in time division duplex (Time Division Duplexing, TDD) mode, the number of beam pairs is equal to the product of the number of network device side beams and the number of terminal device side beams.

Optionally, in TDD mode, the uplink and downlink are peer-to-peer, the uplink transmit beam is the same as the downlink receive beam, and the uplink receive beam is the same as the downlink transmit beam.

Taking fig. 6 as an example, in downlink, beam #1 of the network device is transmitted, and beam x 2 of the terminal device is received; then, on the uplink, beam x 2 of the terminal device is transmitted and beam #1 of the network device is received, so that 8 beams on the network device side and 4 beams on the terminal device side are paired together with 32 beams. At this point the network device may form a TCI pool of 32 beam pairs similar to the left or right half of table 1 from which all channels up and down may select beam pairs.

Optionally, in a frequency division duplex (Frequency Division Duplexing, FDD) mode, the number of beam pairs is equal to a preset multiple of the product of the number of network device side beams and the number of terminal device side beams, preferably the preset multiple is 2.

Alternatively, in FDD mode, different beam pairs may be used for uplink and downlink. For example, in downlink, beam #1 of the network device is transmitted, and beam x 2 of the terminal device is received; on the uplink, the beam of the terminal device is transmitted by 3, and the beam #4 of the network device is received, so that 8 beams on the network device side and 4 beams on the terminal device side are paired together by 64 beams. At this point the network device may form a TCI pool of 64 beam pairs similar to table 1 from which all channels up and down may select beam pairs.

Alternatively, a portion of the generated TCI pool may be selected among all beam pairing manners. For example, if some beams are used only for transmission and not for reception, or only for reception and not for transmission, then the pairing relationship may be reduced accordingly in table 1.

The TCI pool can also take a variety of forms. Optionally, the TCI pool may include information of at least one beam pair. The beam pairs may include network device side beams and terminal device side beams. The information of the beam pair may include at least one of an identification of a network device side beam of the beam pair, an identification of a terminal device side beam, and a measurement result corresponding to the beam pair.

In an example, the TCI pool may include an identifier of a beam on the network device side, an identifier of a beam on the terminal device side, and a measurement result corresponding to a beam pair, and specifically refer to table 1, where the identifier of the beam on the network device side and the identifier of the beam on the terminal device side start with # and # respectively, and on the basis, the measurement result corresponding to each beam pair is added.

Optionally, sending TCI indication information according to the TCI pool may include: determining an uplink reference signal and/or a downlink reference signal in the quasi co-location relation according to the information of at least one beam pair in the TCI pool; and sending TCI indication information according to the uplink reference signal and/or the downlink reference signal in the quasi co-location relation.

Optionally, the most suitable beam pair may be selected from at least one beam pair of the TCI pool for transmitting data, and according to the selected beam pair, a corresponding reference signal may be obtained, so that TCI indication information may be sent, indicating that the data has a quasi co-located relationship with the corresponding reference signal.

Optionally, determining the uplink reference signal and/or the downlink reference signal in the quasi co-sited relation according to the information of at least one beam pair in the TCI pool includes: according to the measurement results corresponding to each beam pair in the TCI pool, an uplink beam pair and/or a downlink beam pair are selected from the TCI pool; and determining an uplink reference signal and/or a downlink reference signal in the quasi co-location relation according to the selected uplink beam pair and/or the downlink beam pair.

Optionally, when the reference signal is selected, the measurement result of the beam pair can be taken as a consideration factor, so that the beam pair with the best quality can be selected from the TCI pool, and the efficiency and the accuracy of data transmission are improved.

In another example, the TCI pool may include an identification of a beam on the network device side, an identification of a beam on the terminal device side, and not necessarily include a measurement result corresponding to a beam pair, and the measurement result corresponding to each beam pair may be stored in other locations, and the measurement result corresponding to each beam pair may be acquired and used from the other locations when needed, so as to reduce the information length required by the TCI pool.

Alternatively, for any beam pair, a measurement result of a signal transmitted by the network device side beam detected by the terminal device side beam may be acquired from the terminal device, and/or for any beam pair, a measurement result corresponding to a signal transmitted by the terminal device side beam may be detected by the network device side beam.

Optionally, the terminal device may receive, through its own beam, a signal transmitted by a beam on the network device side, so as to determine a measurement result of a corresponding beam pair, for example, the terminal device side beam x 1 receives a signal transmitted by the network device side beam #8, and a measurement result obtained by measuring the signal is a measurement result of a beam pair formed by the downlink beam #8 and the beam x 1. The terminal device feeds back the measurement results of each downlink beam pair to the network device, and the network device can update the TCI pool accordingly.

Similarly, the network device side beam may detect a measurement result corresponding to a signal transmitted by the terminal device side beam, for example, the network device side beam #2 receives a signal transmitted by the terminal device side beam x 3, and a measurement result obtained by measuring the signal is a measurement result of a beam pair formed by the uplink beam x 3 and the beam # 2. Therefore, the measuring results corresponding to each beam pair can be rapidly and accurately detected through the network equipment side beam and the terminal equipment side beam, so that basis is provided for beam selection, and the accuracy of beam selection is improved.

Optionally, the measurement results corresponding to the beam pairs may include power information and/or interference noise information. Correspondingly, according to the measurement results corresponding to each beam pair in the TCI pool, selecting an uplink beam pair and/or a downlink beam pair from the TCI pool may include: and selecting an uplink beam pair and/or a downlink beam pair from the TCI pool according to the power information and/or the interference noise information corresponding to each beam pair.

Alternatively, the beam pair with the largest power information or the smallest interference noise information may be selected, or the two may be weighted and summed, and a most suitable beam pair may be selected according to the obtained result, thereby determining the corresponding reference signal.

In determining the reference signal in the quasi co-sited relation, only the uplink reference signal may be determined, which indicates that a certain uplink data has a quasi co-sited relation with the uplink reference signal, for example, in the TCI pool, the beam pair formed by beam x 2 and beam #3 is best in quality, and corresponds to the uplink reference signal 11, i.e. the reference signal 11 is transmitted with beam x 2, and the beam #3 is received, which may indicate that the uplink data, such as PUCCH and/or PUSCH, has a quasi co-sited relation with the uplink reference signal 11, so that the terminal device may know that the uplink data needs to be transmitted through beam x 2 according to the quasi co-sited relation.

Alternatively, when determining the reference signal in the quasi co-sited relation, only the downlink reference signal may be determined, which indicates that a certain downlink data has the quasi co-sited relation with the downlink reference signal, for example, in the TCI pool, the beam pair formed by the beam #1 and the beam x 4 has the best quality, and the beam pair corresponds to the downlink reference signal 36, that is, the reference signal 36 is transmitted by the beam #1, and the beam x 4 is received, and then the downlink data, such as PDCCH and/or PDSCH, may be indicated to have the quasi co-sited relation with the downlink reference signal 36, so that the terminal device may know that the downlink data needs to be received by the beam x 4 according to the quasi co-sited relation.

Alternatively, in determining the reference signals in the quasi co-sited relationship, both the uplink reference signals and the downlink reference signals may be determined. For example, in the TCI indication information, it may be indicated that the uplink data and the uplink reference signal 11 have a quasi co-address relationship, and the downlink data and the downlink reference signal 36 have a quasi co-address relationship, so that the terminal device may know that the uplink data needs to be transmitted by using the beam x 2 and receive the downlink data by using the beam x 4 according to the quasi co-address relationship.

Fig. 7 is a schematic diagram of data transmission based on a beam according to an embodiment of the present application. As shown in fig. 7, when it is determined that data has a quasi co-located relationship with a certain reference signal, a beam pair corresponding to the reference signal may be used for data transmission.

For example, the TCI indication information indicates that the PDSCH has a quasi co-location relationship with a downlink reference signal, where the beam pair corresponding to the downlink reference signal is: the network device side may transmit PDSCH using beam #4 and the terminal device side may receive PDSCH using beam x 1.

In practical application, the network device and the terminal device can scan the wave beams in advance, that is, traverse all wave beam pairing modes to transmit and receive the reference signals, store the measurement results of the wave beam pairs obtained in the wave beam scanning process, and select the wave beam pair with the best measurement result from the TCI pool to indicate the co-location relation by the TCI indication information when uplink data or downlink data is required to be transmitted.

In the first alternative implementation manner described above, the TCI pool may be determined according to the beam set of the uplink reference signal and the beam set of the downlink reference signal, so that an indication of a quasi co-location relationship between uplink data and downlink data can be implemented, and transmission requirements of various data are satisfied.

In a second alternative implementation, the TCI pool may be determined from a set of beams of the uplink reference signal. Optionally, the beam set of the uplink reference signal may include all uplink transmission beams and/or uplink reception beams during beam scanning.

Accordingly, determining the TCI pool according to the beam set of the uplink reference signal may include: and determining a TCI pool according to all pairs of transmitting beams and receiving beams in the beam set of the uplink reference signals.

In such an implementation, only the beam set of the uplink reference signal may be considered, and the TCI pool may be embodied with reference to the right half of table 1.

According to the TCI pool, a proper beam pair can be selected for uplink data, so that the quasi co-location relation between the uplink data and an uplink reference signal is indicated. Alternatively, in some implementations, the quasi co-location relationship between the downlink data and the uplink reference signal may also be indicated, that is, the downlink data may be transmitted and received through two beams corresponding to the uplink reference signal. For example, if the PDCCH and the uplink reference signal 11 are quasi co-located, and the uplink reference signal 11 corresponds to the beam x 2 and the beam #3, the PDCCH may transmit and receive using the beam x 2 and the beam #3, and the transmit beam and the receive beam are just opposite to the uplink reference signal 11.

In a third alternative implementation, the TCI pool may be determined from a set of beams of the downlink reference signals. Optionally, the beam set of the downlink reference signal may include all downlink transmit beams and/or downlink receive beams during beam scanning.

Accordingly, determining the TCI pool according to the beam set of the downlink reference signal may include: and determining a TCI pool according to all pairs of transmitting beams and receiving beams in the beam set of the downlink reference signals.

In such an implementation, only the beam set of the downlink reference signal may be considered, and the TCI pool may be embodied with reference to the left half of table 1.

According to the TCI pool, a proper beam pair can be selected for downlink data, so that the quasi co-location relation between the downlink data and a downlink reference signal is indicated. Alternatively, in some implementations, the quasi co-location relationship between the uplink data and the downlink reference signal may also be indicated, that is, the uplink data may be transmitted and received through two beams corresponding to the downlink reference signal. For example, if the PUCCH is quasi co-located with the downlink reference signal 36, and the downlink reference signal 36 corresponds to beam #1 and beam x 4, the PUCCH may be transmitted and received using beam #1 and beam x 4, except that the transmit beam and the receive beam are exactly opposite to the downlink reference signal 36.

In the second and third alternative implementations, the scheme of determining the TCI pool according to the beam set of the uplink reference signal only or the beam set of the downlink reference only is provided, and other places not described may refer to the first alternative implementation, which is not described herein.

In practical application, the TCI pool is determined only according to the beam set of the uplink reference signal or the beam set of the downlink reference signal, so that the TCI pool can be effectively simplified, the information length of the TCI pool is reduced, the content of the TCI pool can be determined according to practical requirements, and the application requirements under different scenes are met.

On the basis of the technical solutions provided in the foregoing embodiments, optionally, sending TCI indication information includes: downlink control information (Downlink Control Information, DCI) is sent over the PDCCH, the DCI including TCI indication information.

The quasi co-address relationship indicated in the DCI can include either an uplink quasi co-address relationship or a downlink quasi co-address relationship, so that the indication of uplink and downlink can be realized through the DCI at the same time, the quasi co-address relationship is not required to be indicated in each channel, and the flexibility of TCI indication is improved.

Optionally, the TCI indication information may include at least one of: the identification of the uplink reference signal in the quasi co-located relationship; the identification of the downlink reference signal in the quasi co-located relationship; identification of a reference signal combination; channel indication information.

In one example, the TCI indication information may include an identification of an uplink reference signal in the quasi co-located relationship and/or an identification of a downlink reference signal in the quasi co-located relationship. The identification of the reference signal directly indicates the quasi co-location relation, so that the efficiency and the accuracy of determining the quasi co-location relation by the terminal equipment can be effectively improved.

Optionally, when the TCI indication information includes an identification of an uplink reference signal and/or an identification of a downlink reference signal in the quasi co-located relation, the TCI indication information may further include: an uplink indication bit corresponding to the identification of the uplink reference signal; and/or a downlink indication bit corresponding to the identification of the downlink reference signal.

Optionally, the uplink indication bit may be used to indicate that the corresponding set identifier is an identifier of the uplink reference signal, and the downlink indication bit may be used to indicate that the corresponding set identifier is an identifier of the downlink reference signal.

Table 2 an example of TCI indication information provided by an embodiment of the present application

TCI-0

11

TCI-1

36

As shown in table 2, the uplink indicator bit may be TCI-0, for indicating that the corresponding set identifier 11 is an identifier of the uplink reference signal, that is, the reference signal in the quasi co-located relationship includes the uplink reference signal 11; similarly, the downlink indicator bit may be TCI-1, which indicates that the corresponding set identifier 36 is an identifier of a downlink reference signal, i.e., the reference signal in the quasi co-sited relationship includes the uplink reference signal 36.

Alternatively, the TCI indication information may only indicate an uplink quasi co-address relationship or only indicate a downlink quasi co-address relationship, and accordingly, only an uplink indication bit or a downlink indication bit may be set in the TCI indication information. The TCI indication information can enable the terminal to accurately know whether the indicated quasi co-location relationship is applied to uplink or downlink, and further improve the accuracy of determining the quasi co-location relationship by the terminal.

The terminal device may maintain a correspondence between reference signals and beams. After receiving the TCI indication information, the terminal device can determine the reference signal in the quasi co-location relationship according to the TCI indication information, and further can determine the beam corresponding to the reference signal.

Optionally, the terminal device may store a transmit beam corresponding to the uplink reference signal and/or a receive beam corresponding to the downlink reference signal, and if it may be determined that the corresponding transmit beam and receive beam are respectively equal to x 2 and x 1 according to the uplink reference signal 11 and the downlink reference signal 36, uplink data may be transmitted by the beam x 2 and downlink data may be received by the beam x 1.

In another example, the TCI indication information may include an identification of a reference signal combination. Optionally, the reference signal combination includes an uplink reference signal and a downlink reference signal in the quasi co-sited relationship.

In the case that the uplink reference signal and the downlink reference signal need to be indicated at the same time, the uplink reference signal and the downlink reference signal in the quasi co-sited relationship can be represented by the identification of one reference signal combination.

For example, there are n optional uplink reference signals and m optional downlink reference signals, and then there are n×m combinations, where any one uplink reference signal and any one downlink reference signal are combined.

Optionally, when the TCI indication information needs to include the identifier of the reference signal combination, the network device may first select an appropriate beam according to the beam measurement result and determine a corresponding uplink reference signal and a corresponding downlink reference signal, then determine a corresponding reference signal combination according to the uplink reference signal and the downlink reference signal, and determine the identifier of the reference signal combination according to the corresponding reference signal combination.

The terminal device may maintain a correspondence between the identifier of the reference signal combination and the uplink reference signal and the downlink reference signal. The uplink reference signal and the downlink reference signal can be accurately indicated through the identification of the reference signal combination, and the information length of transmission can be saved.

In yet another example, the TCI indication information may include channel indication information. The channel indication information is used to indicate a channel using the quasi co-sited relationship. Alternatively, the channel indication information may be used to indicate that any one or more of PDCCH, PDSCH, PUCCH, PUSCH use the quasi co-sited relationship.

In this way, the terminal device can determine which channels need to use the quasi co-location relationship indicated in the TCI indication information according to the channel indication information, so as to improve the accuracy of TCI indication.

Alternatively, the quasi co-location relationship between each channel and the reference signal may be time-limited, and after the reference signal is determined, the channel and the reference signal may be quasi co-located for a period of time, thereby improving the real-time performance of the quasi co-location relationship.

Based on the technical solutions provided in the foregoing embodiments, optionally, the TCI indication information may also be configured by a radio resource control layer (Radio Resource Control, RRC) and/or a medium access control layer (Media Access Control Control Element, MAC CE) for at least one of: PDCCH, PDSCH, PUCCH, PUSCH.

Alternatively, higher layer signaling may configure which channel or channels use TCI indication information. At the physical layer, the DCI may directly send TCI indication information to indicate the quasi co-sited relationship. In this way, after the terminal device acquires the DCI, it can know to which channel the indicated quasi co-location relationship can be applied, reducing the complexity of the DCI.

When the quasi co-sited relation is changed, the quasi co-sited relation is changed in DCI directly. When the DCI carries channel indication information and the channel indication information conflicts with information configured by a high-layer signaling, the DCI can be used for carrying channel indication information, so that terminal equipment can be rapidly notified when quasi co-location changes, and information transmission efficiency is improved.

Based on the technical solutions provided in the foregoing embodiments, optionally, the quasi co-location relationship indicated by the TCI indication information includes at least one uplink reference signal and at least one downlink reference signal.

Optionally, when the quasi co-sited relation includes a plurality of uplink reference signals, the terminal device may transmit signals through a plurality of beams, and/or the network device may receive signals through a plurality of beams; when multiple downlink reference signals are included in the quasi co-sited relationship, the network device may transmit signals over multiple beams and/or the terminal device may receive signals over multiple beams. Thus, the signal can be transmitted or received through a plurality of beams, and the accuracy of signal transmission is improved.

Alternatively, the terminal device may not perform the quasi co-location relationship indicated by the TCI indication information on carrier B, assuming that the connection configuration information indicates carrier B.

Alternatively, the terminal device may perform the quasi co-sited relationship on other carriers than the carrier indicated by the connection configuration information.

In yet another alternative implementation, the connection configuration information may be used to indicate whether the terminal device performs the quasi co-sited relationship on two or more carriers.

Optionally, the terminal device may perform the quasi co-location relationship on at least two carriers indicated by the connection configuration information simultaneously; or, the terminal device may not perform the quasi co-location relationship on at least two carriers indicated by the connection configuration information; alternatively, the terminal device may perform the quasi co-sited relationship on a part of carriers among at least two carriers indicated by the connection configuration information, and not perform the quasi co-sited relationship on the remaining carriers.

Alternatively, the terminal device may use the quasi co-sited relation indicated by the TCI indication information on some carriers indicated by the connection configuration information, and use other quasi co-sited relations than the quasi co-sited relation indicated by the TCI indication information on other carriers.

Alternatively, the primary cell information/secondary cell information may be any information capable of indicating a primary cell/secondary cell, for example: the identity, name, corresponding carrier information, etc. of the primary/secondary cell.

The method comprises the steps that a main carrier can be determined according to a main cell, an auxiliary carrier can be determined according to an auxiliary cell, and at least one of the main carrier and the auxiliary carrier can be determined according to at least one of the main cell and the auxiliary cell, so that quasi co-location relation configuration for the main carrier and the auxiliary carrier can be realized, quasi co-location relation configuration under a carrier aggregation scene is realized, and system flexibility under the carrier aggregation scene is improved.

On the basis of the technical solutions provided in the foregoing embodiments, optionally, the connection configuration information includes at least one of the following: primary cell information of the primary node; secondary cell information of the primary node; primary cell information of the secondary node; secondary cell information of the secondary node.

Considering the dual link (Dual Connectivity, DC) scenario, the DC may contain a Master Node (MN) and a secondary Node (Secondary Node SN), where each Node may have its own CA combination. The connection configuration information may be used to indicate a primary cell and/or a secondary cell in the primary node and/or the secondary node. For example, the primary cell information/secondary cell information may be an identification, a name, corresponding carrier information, etc. of the primary cell/secondary cell.

In one example, the connection configuration information may be used to indicate any one of a primary cell of the primary node, a secondary cell of the primary node, a primary cell of the secondary node, and a secondary cell of the secondary node. For example, if the connection configuration information indicates a primary cell of a primary node, the terminal device may configure in advance a quasi co-location relationship indicated by the TCI indication information to be performed or not performed on a carrier corresponding to the primary cell of the primary node.

In another example, the connection configuration information may be used to indicate at least two of a primary cell of the primary node, a secondary cell of the primary node, a primary cell of the secondary node, and a secondary cell of the secondary node.

By acquiring the TCI indication information before the uplink data and the downlink data are transmitted based on the connection configuration information and the TCI indication information, the TCI indication information corresponding to the data transmission at this time can be determined in real time, and the efficiency and the accuracy of the data transmission are improved.

In an alternative implementation, the connection configuration information may be acquired first, and then the TCI indication information may be acquired. For example, the connection configuration information may be obtained through radio resource control signaling, and the TCI indication information may be obtained through DCI, so that the terminal device may determine in advance which carriers need to execute the quasi co-location relationship indicated by the TCI indication information, and then determine in real time which quasi co-location relationship is specifically used according to the TCI indication information, thereby improving flexibility of quasi co-location relationship indication.

In yet another alternative implementation, the connection configuration information and the TCI indication information may be acquired simultaneously. For example, the connection configuration information and the TCI indication information may be obtained through radio resource control signaling or DCI, so that the terminal device may synchronously know how to select the quasi co-sited relationship and configure which carriers to use the quasi co-sited relationship, thereby improving the processing efficiency of the terminal device.

Optionally, the method further comprises: configuring the TCI indication information for at least one of the following by a radio resource control layer and/or a medium access control layer: physical uplink control channel, physical uplink shared channel, physical downlink control channel, physical downlink shared channel.

Higher layer signaling may configure which channel or channels use TCI indication information. At the physical layer, the DCI may directly send TCI indication information to indicate the quasi co-sited relationship. In this way, after the terminal device acquires the DCI, it can know to which channel the indicated quasi co-location relationship can be applied, reducing the complexity of the DCI.

When the quasi co-located relation includes a plurality of uplink reference signals, the terminal device may transmit signals through a plurality of beams, and/or the network device may receive signals through a plurality of beams; when multiple downlink reference signals are included in the quasi co-sited relationship, the network device may transmit signals over multiple beams and/or the terminal device may receive signals over multiple beams. Thus, the signal can be transmitted or received through a plurality of beams, and the accuracy of signal transmission is improved.

step 1001, determining connection configuration information.

Step 1002, performing downlink data transmission and/or uplink data reception according to the connection configuration information and the TCI indication information.

Alternatively, it may be determined which reference signal corresponds to a beam to use for downlink data reception and/or uplink data transmission according to the quasi co-location relationship indicated by the TCI indication information. It is also possible to determine how to use the quasi co-sited relationship based on carriers based on connection configuration information.

For example, it may be determined whether to perform the quasi co-location relationship indicated by the TCI indication information on the corresponding carrier based on the connection configuration information. Specific implementation methods may be referred to the foregoing embodiments, and will not be described herein.

According to the quasi co-location relation indicating method provided by the embodiment, the connection configuration information can be determined, downlink data is sent and/or uplink data is received according to the connection configuration information and the TCI indicating information, optionally, the TCI indicating information is used for indicating the quasi co-location relation of data and reference signals, so that the quasi co-location relation is rapidly and accurately executed in a mode of adding the TCI indicating information to the connection configuration information, TCI lists are not required to be configured in each channel, redundancy and complexity of information configuration are effectively reduced, system efficiency is improved, quasi co-location relation of different carriers is indicated, and flexibility of a system is improved.

Optionally, the method further comprises: determining a TCI pool according to the beam set of the uplink reference signal and/or the downlink reference signal; and sending TCI indication information according to the TCI pool.

In practical application, a TCI pool may be configured at the network device side, where a beam set corresponding to a reference signal is stored in the TCI pool, when a quasi co-location relationship is needed to be used, an appropriate beam may be selected from the TCI pool, a corresponding reference signal may be determined according to the selected beam, then TCI indication information is sent, and indication data may be quasi co-located with the reference signal, so that the terminal device may determine which beam corresponding to the reference signal is used to receive or send data according to the quasi co-location relationship indicated by the TCI indication information.

Therefore, the indication of the quasi co-location relationship can be realized by adding TCI indication information to the TCI pool, a TCI state list is not required to be configured in each channel, and when the beam set is changed, the TCI pool is directly modified, so that the efficiency of quasi co-location relationship configuration is improved.

The configuration of quasi co-location relation can be carried out on carriers in advance through the radio resource control instruction, and the processing efficiency of the terminal equipment is improved.

Optionally, the radio resource control signaling further comprises a TCI pool. The terminal equipment can acquire the TCI pool based on the radio resource control signaling, and can directly determine which item in the TCI pool is used for transmitting and receiving data according to the TCI indication information, so that the indication of the alignment co-location relationship can be effectively simplified, and the signaling overhead is reduced.

Optionally, before the downlink data is sent and/or the uplink data is received according to the connection configuration information and the TCI indication information, the method further includes: and sending the connection configuration information. By transmitting the TCI indication information before the uplink data and the downlink data are transmitted based on the connection configuration information and the TCI indication information, the terminal equipment can timely determine the TCI indication information corresponding to the data transmission, and the efficiency and the accuracy of the data transmission are improved.
