Description

Wireless communication method, terminal equipment and network equipment

Technical Field

The embodiment of the application relates to the field of communication, in particular to a wireless communication method, terminal equipment and network equipment.

Background

Quasi Co-Location (QCL) refers to the large scale parameters of a channel experienced by a symbol on one antenna port can be inferred from the channel experienced by a symbol on another antenna port. The large scale parameters may include delay spread, average delay, doppler spread, doppler shift, average gain, spatial reception parameters, etc.

In a New Radio (NR) system, a satellite communication manner is considered to provide a communication service for a user, where a satellite uses multiple beams to cover the ground, which is called a New Radio Non-terrestrial communication network (NR-NTN) scenario, and in the NR-NTN scenario, a beam deployment situation of the satellite may include: a synchronization signal block (Synchronization Signal Block, SSB) corresponds to a terrestrial cell, or the beam width of SSB transmission is consistent with the beam width of data transmission; alternatively, one SSB corresponds to a plurality of terrestrial cells, or the beam width of SSB transmission and the beam width of data transmission are not identical.

In the NR-NTN scene, the antenna polarization modes of the satellite are multiple, and adjacent cells possibly use different antenna polarization modes, so that the interference between the cells is reduced, and if the antenna polarization modes of the satellite and the terminal equipment are matched, the receiving performance can be improved; if the antenna polarization patterns of the satellite and the terminal device do not match, the reception performance is degraded and even the signal cannot be received. Therefore, the antenna polarization mode needs to be notified in both downlink and uplink transmissions in the NR-NTN scenario. Therefore, how to determine QCL relationships and antenna polarization modes to improve system performance in NR-NTN scenarios is a need to be addressed.

It should be understood that the terms "system" and "network" are used interchangeably herein. The term "and/or" is herein merely an association relationship describing an associated object, meaning that there may be three relationships, e.g., a and/or B, may represent: a exists alone, A and B exist together, and B exists alone. In addition, the character "/" herein generally indicates that the front and rear associated objects are an "or" relationship.

It should be understood that the "indication" mentioned in the embodiments of the present application may be a direct indication, an indirect indication, or an indication having an association relationship. For example, a indicates B, which may mean that a indicates B directly, e.g., B may be obtained by a; it may also indicate that a indicates B indirectly, e.g. a indicates C, B may be obtained by C; it may also be indicated that there is an association between a and B.

In some embodiments of the present application, "predefined" may be implemented by pre-storing corresponding codes, tables, or other means that may be used to indicate relevant information in devices (e.g., including terminal devices and network devices), and the present application is not limited to a particular implementation thereof. Such as predefined, may refer to what is defined in the protocol.

In some embodiments of the present application, the "protocol" may refer to a standard protocol in the field of communications, and may include, for example, an LTE protocol, an NR protocol, and related protocols applied in future communication systems, which is not limited by the present application.

In the NR system, considering possible QCL relationships between various reference signals, the above-mentioned channel large-scale parameters may be divided into different QCL types, so that the system is convenient to configure according to different scenarios where the terminal device is located.

As an example, the definition of different QCL type configurations is as follows:

'QCL-TypeA': doppler shift (Doppler shift), doppler spread (Doppler spread), average delay (average delay), delay spread (delay spread) };

'QCL-TypeB': { Doppler shift (Doppler shift), doppler spread (Doppler spread) };

'QCL-TypeC': { Doppler shift (Doppler shift), average delay (average delay) };

'QCL-TypeD': spatial reception parameters (Spatial Rx parameter).

The beam network deployment in the NR-NTN scene comprises the following two cases:

case 1: as shown in fig. 2A. One synchronization signal block (Synchronization Signal Block, SSB) corresponds to one terrestrial cell, or the beam width of SSB transmission coincides with the beam width of data transmission. One terrestrial cell corresponds to one BWP for data transmission. After the terminal device accesses the network through the SSB on the initial bandwidth Part (BWP) (i.e., bwp#0), the network device configures the terminal device with the BWP corresponding to the SSB when the terminal device accesses for data transmission. In addition, as shown in fig. 2A, channel state information reference signals (Channel State Information Reference Signal, CSI-RS) may also be transmitted in Downlink (DL) bwp#1 to DL bwp#3, and the beam width and beam direction of the CSI-RS transmission coincide with those of the data transmission. As an example, the beam width and beam direction of the CSI-RS on DL BWP #2 of cell #1 are the same as those of SSB #1 of cell # 1. In some cases, it may be considered that the large scale parameters of doppler shift, doppler spread, average delay and delay spread of the channel experienced by ssb#1 of cell#1 may be used as QCL references for CSI-RS on DL bwp#2 of that cell#1, or that ssb#1 is the QCL reference signal for CSI-RS on DL bwp#2, the QCL type of which is 'QCL-type a'.

Case 2: as shown in fig. 2B. One SSB corresponds to a plurality of terrestrial cells, or the beam width of SSB transmission is inconsistent with the beam width of data transmission, or the beam width of SSB transmission is greater than the beam width of data transmission. One terrestrial cell corresponds to one BWP for data transmission. After the terminal device accesses the network through the SSB on the initial BWP (i.e., bwp#0), the network device configures the terminal device with the BWP corresponding to the SSB when the terminal device accesses for data transmission. Further, as shown in fig. 2B, CSI-RS may also be transmitted in DL bwp#1 to DL bwp#3, and the beam width and beam direction of the CSI-RS transmission coincide with those of the data transmission. As an example, the beam of ssb#1 of cell#1 includes beams of CSI-RS on DL bwp#1, CSI-RS on DL bwp#2, and CSI-RS on DL bwp#3 of cell#1. In some cases, such a scene may also be referred to as an umbrella beam scene. In some cases, it may be considered that the large scale parameters of doppler shift and doppler spread of the channel experienced by ssb#1 of cell#1 may be used as QCL reference for CSI-RS on DL bwp#1 or DL bwp#2 or DL bwp#3 of the cell#1, or that ssb#1 is the QCL reference signal for CSI-RS on DL bwp#1 or DL bwp#2 or DL bwp#3, and the QCL type is 'QCL-TypeB'.

In an NR-NTN scenario, the antenna polarization mode of the satellite includes at least one of right-hand polarization (Right Hand Circular Polarization, RHCP), left-hand polarization (Left Hand Circular Polarization, LHCP), and linear polarization (Linear Polarization, LP). The antenna polarization mode of the terminal device also includes at least one of right-hand polarization, left-hand polarization and linear polarization.

In the NR-NTN scenario, different polarization modes may be used for neighboring cells, thereby mitigating inter-cell interference in the network deployment scenario. If the antenna polarization modes of the satellite and the terminal equipment are matched, the receiving performance can be increased; if the antenna polarization patterns of the satellite and the terminal device do not match, the reception performance is degraded and even the signal cannot be received. In addition, in the above network deployment scenario, if the terminal device further extends the QCL relationship determining method in the related art, the resource configuration will be inefficient. Therefore, how to determine QCL relationships and antenna polarization modes to improve system performance in NR-NTN scenarios is a need to be addressed.

In order to facilitate understanding of the technical solution of the embodiments of the present application, the technical solution of the present application is described in detail below through specific embodiments. The above related technologies may be optionally combined with the technical solutions of the embodiments of the present application, which all belong to the protection scope of the embodiments of the present application. Embodiments of the present application include at least some of the following.

Fig. 3 is a schematic interaction diagram of a method 200 of wireless communication according to an embodiment of the application, as shown in fig. 3, the method 200 comprising:

s201, the terminal device determines that the antenna polarization mode corresponding to the first physical channel or the first reference signal transmission on the first bandwidth portion BWP is the first antenna polarization mode, and/or,

In some embodiments of the present application, the first BWP may include a first upstream BWP and/or a first downstream BWP.

In some cases, denoted as case 1, the first BWP is a BWP on a first cell, the first cell corresponds to a plurality of BWP, and an antenna polarization mode corresponding to physical channels or reference signal transmission on the plurality of BWP is the first antenna polarization mode.

In other words, physical channel transmission or reference signal transmission on the same cell uses the same antenna polarization pattern. Alternatively, the antenna polarization pattern is cell-granularity.

In other cases, denoted as case 2, the first BWP is a BWP on a first cell, where the first cell corresponds to a plurality of BWPs, and a determination manner of an antenna polarization mode corresponding to a physical channel or a reference signal transmission on other BWPs in the plurality of BWPs is the same as a determination manner of an antenna polarization mode corresponding to a first physical channel or a first reference signal transmission on the first BWP.

It should be understood that physical channel transmission or reference signal transmission on different BWP on the same cell may use the same antenna polarization mode, or may also use different antenna polarization modes. Alternatively, the antenna polarization pattern is BWP granularity.

In the following, an example of determining an antenna polarization mode corresponding to physical channels or reference signal transmission on the first BWP is described, for the case 1, the determined antenna polarization mode is an antenna polarization mode corresponding to physical channels or reference signal transmission on the first cell corresponding to the first BWP, and for the case 2, the terminal device may also determine an antenna polarization mode corresponding to physical channels or reference signal transmission on other BWP on the first cell according to a manner of determining an antenna polarization mode corresponding to physical channels or reference signal transmission on the first BWP, which is not repeated herein for brevity.

In some embodiments, the first BWP is an active BWP on the first cell. If there are multiple active BWP on the first cell, the first BWP may be any BWP on the multiple active BWP.

In some embodiments, the first BWP comprises a first downstream BWP and the second BWP comprises a second downstream BWP.

That is, the second reference signal on the second downlink BWP may be a QCL reference signal of the first reference signal on the first downlink BWP.

In still other embodiments, the first BWP comprises a first upstream BWP and the second BWP comprises a second downstream BWP.

That is, the second reference signal on the second downlink BWP may be used as the QCL reference signal of the first reference signal on the first uplink BWP. It should be understood that the QCL reference signal corresponding to the first reference signal on the first uplink BWP is the second reference signal on the second downlink BWP, and may be a large scale parameter of the second reference signal or the antenna polarization mode may be used as the QCL reference of the first reference signal. In some cases, the QCL reference is determined from a transceiver correspondence.

In some embodiments of the present application, the second BWP may be an initial BWP.

For another example, the terminal device may determine the antenna polarization mode corresponding to the physical channel or the reference signal transmission on the non-initial BWP according to the antenna polarization mode corresponding to the physical channel or the reference signal transmission on the initial BWP.

In some embodiments, the second BWP comprises a second downstream BWP, which is an initial downstream BWP.

For example, the reference signal on the initial downlink BWP may be a QCL reference signal that is a reference signal on a non-initial downlink BWP.

For another example, the terminal device may determine the antenna polarization mode corresponding to the physical channel or the reference signal transmission on the non-initial downlink BWP according to the antenna polarization mode corresponding to the physical channel or the reference signal transmission on the initial downlink BWP. In other embodiments, the second BWP comprises a second upstream BWP, which is an initial upstream BWP.

For example, the reference signal on the initial upstream BWP may be a QCL reference signal that is not the reference signal on the initial upstream BWP.

For another example, the terminal device may determine the antenna polarization mode corresponding to the physical channel or the reference signal transmission on the non-initial uplink BWP according to the antenna polarization mode corresponding to the physical channel or the reference signal transmission on the initial uplink BWP.

In some embodiments, the second BWP comprises one BWP and the first BWP comprises a plurality of BWP.

For example, the plurality of reference signals on the second BWP may be QCL reference signals as reference signals on the plurality of BWP included in the first BWP. Wherein, the plurality of reference signals on the second BWP are in one-to-one correspondence with the plurality of BWPs included in the first BWP.

For another example, the terminal device may determine the antenna polarization mode corresponding to the physical channels or the reference signal transmission on the plurality of BWP included in the first BWP according to the antenna polarization mode corresponding to the plurality of physical channels or the reference signal transmission on the second BWP. Wherein, the plurality of physical channels or reference signals on the second BWP are in one-to-one correspondence with the plurality of BWP included in the first BWP.

In other embodiments of the present application, the first BWP and the second BWP are the same BWP, i.e. all reference signals on the same BWP may be considered as having a QCL relationship.

In some embodiments, all reference signals on the first BWP may be considered to have a QCL relationship.

In some embodiments, the uplink antenna polarization pattern is reported by the terminal device to the network device. For example, the terminal device reports the uplink antenna polarization mode supported by the terminal device to the network device. Further, the network device instructs the terminal device on the corresponding antenna polarization mode when transmitting the physical signal or the physical channel on the uplink BWP.

In some embodiments of the present application, the first antenna polarization mode may be determined based on first configuration information transmitted by the network device.

As example 2, the first QCL type may be one of the following:

'QCL-TypeC': { Doppler shift (Doppler shift), average delay (average delay) };

The antenna polarization mode can be added in the parameters corresponding to the existing QCL type D, so that the enhanced QCL type D is obtained.

Further, selecting, by the MAC CE, at most 8 TCI states from the M TCI states, where the M TCI states correspond to the TCI indication information in the DCI if the value of M is less than or equal to 8. And selecting one TCI state from the TCI states corresponding to the TCI indication information in the DCI through the DCI, and taking the TCI state as a QCL reference signal of the first reference signal.

QCL reference signal configuration includes a cell ID, BWP ID, and an identity of the reference signal (e.g., CSI-RS resource ID or SSB index) where the reference signal is located.

Wherein, the QCL type of at least one QCL information of QCL information 1, QCL information 2 and QCL information 3 is one of QCL type a, QCL type b, QCL type c, the QCL type of one QCL information (if configured) of the other two QCL information is QCL type D, and the QCL type of the other QCL information (if configured) of the other two QCL information is QCL type E.

As an example, for frequency bands below 6GHz, the available QCL reference signal of PDSCH DMRS may include one of the cases shown in table 1:

As another example, for frequency bands above 6GHz, the available QCL reference signals of PDSCH DMRS may include one of the cases shown in table 2:

TABLE 2

In some embodiments, if the QCL type configuration information does not include the antenna polarization parameter, the antenna polarization mode corresponding to the first physical channel or the first reference signal on the first BWP may be determined as follows.

In other embodiments of the present application, the first antenna polarization mode is determined according to a first association relationship, where the first association relationship is used to characterize an association relationship between the antenna polarization mode and the BWP.

For example, if the first BWP corresponds to the first antenna polarization mode in the first association relationship, the terminal device may determine that the antenna polarization mode corresponding to the first physical channel or the first reference signal transmission on the first BWP is the first antenna polarization mode.

In some embodiments, the first association may include an association between a downlink antenna polarization mode and a BWP and/or an association between an uplink antenna polarization mode and a BWP.

In some embodiments, the first association may be predefined and/or configured by a network device.

For example, the network device configures the first association through at least one of a system message, RRC signaling, MAC CE, and DCI.

In some embodiments, the first association may be included in the second configuration information. The second configuration information may be any configuration information sent by the network device to the terminal device, for example, BWP configuration information, band configuration information, etc.

Alternatively, the second configuration information may be transmitted through at least one of a system message, RRC signaling, MAC CE, and DCI.

In still further embodiments of the present application, the first antenna polarization mode is determined according to a first QCL relationship for characterizing a QCL relationship of the BWP identification ID and the reference signal index and/or a second association relationship for characterizing an association relationship of the antenna polarization mode and the reference signal index.

In some embodiments, the QCL relationships in the first QCL relationship may represent:

all reference signals on BWP corresponding to the BWP ID and SSBs indicated by SSB indexes corresponding to the BWP ID have QCL relations; or alternatively, the process may be performed,

the BWP corresponding reference signal of the BWP ID and the SSB indicated by the SSB index of the BWP ID have QCL relationships. Alternatively, the reference signal corresponding to the first BWP may refer to a reference signal transmitted on the first BWP, or a reference signal on another BWP having a QCL relationship with the reference signal on the first BWP.

In some embodiments, the first antenna polarization mode is an antenna polarization mode associated with a reference signal corresponding to the first BWP. Alternatively, the reference signal corresponding to the first BWP may refer to a reference signal transmitted on the first BWP, or a reference signal on another BWP having a QCL relationship with the reference signal on the first BWP.

As an example, in the first QCL relationship, the first BWP corresponds to the second reference signal, and in the second association relationship, the second reference signal corresponds to the first antenna polarization mode, and the antenna polarization mode of the first reference signal on the first BWP may be determined as the first antenna polarization mode.

In some embodiments, the reference signal index may include an SSB index and/or a CSI-RS Identification (ID).

As an example, the first QCL relationship may be a QCL relationship of BWP ID and SSB index.

As an example, the second association relationship may be an association relationship between an antenna polarization mode and an SSB index.

In some embodiments, the second association may include an association between a downlink antenna polarization mode and a reference signal index and/or an association between an uplink antenna polarization mode and a reference signal index.

As an example, the association relationship between the downlink antenna polarization mode and the SSB index may include:

{ SSB0, polarization mode 0}, { SSB1, polarization mode 1}, { SSB2, polarization mode 2}.

As an example, the association relationship between the uplink antenna polarization mode and the SSB index may include:

{ SSB0, upstream polarization mode 0}, { SSB1, upstream polarization mode 1}, { SSB2, upstream polarization mode 2}.

If the terminal equipment accesses the network through SSB0, the terminal equipment can adopt an uplink polarization mode 0 corresponding to SSB0 for uplink transmission; or if the terminal equipment accesses the network through the SSB1, the terminal equipment adopts an uplink polarization mode 1 corresponding to the SSB1 to carry out uplink transmission; or if the terminal equipment accesses the network through the SSB2, the terminal equipment adopts the uplink polarization mode 2 corresponding to the SSB2 to carry out uplink transmission.

As another example, the network device may configure whether circular polarization is supported, and if so, the second association relationship may be predefined. For example, SSB associated RHCP corresponding to odd SSB indexes, SSB associated LHCP corresponding to even SSB indexes; alternatively, SSBs corresponding to even SSB indexes are associated with RHCP, and SSBs corresponding to odd SSB indexes are associated with LHCP. Or if circular polarization is not supported, the antenna polarization mode associated with the SSB corresponding to any SSB index is LP.

As another example, the terminal device may report to the network device whether the terminal device supports circular polarization. If the terminal equipment supports circular polarization, the terminal equipment performs uplink transmission according to the association relation between the uplink antenna polarization mode and the SSB index. Or if circular polarization is not supported, the terminal equipment determines that the uplink antenna polarization mode is LP.

In some embodiments of the application, the first QCL relationship is predefined or configured by a network device.

For example, the network device configures the first QCL relationship through at least one of system messages, RRC signaling, MAC CEs, and DCIs.

In some embodiments, the first QCL relationship may be included in third configuration information. Alternatively, the third configuration information may be any configuration information that is sent by the network device to the terminal device, for example, BWP configuration information, band configuration information, and the like.

In some embodiments, the third configuration information may be transmitted through at least one of a system message, RRC signaling, MAC CE, and DCI.

In some embodiments of the present application, the second association is predefined or configured by the network device.

For example, the network device transmits the second association through at least one of a system message, RRC signaling, MAC CE, and DCI.

In some embodiments, the second association relationship may be included in fourth configuration information. Alternatively, the fourth configuration information may be transmitted through at least one of a system message, RRC signaling, MAC CE, and DCI.

In some embodiments, the fourth configuration information may be any configuration information that is sent by the network device to the terminal device, for example, BWP configuration information, band configuration information, and the like.

In some embodiments of the application, the first antenna polarization mode is used for radio resource management (Radio Resource Management, RRM) measurements and/or radio link management (radio link monitoring, RLM) measurements.

In some embodiments, the second association is for RRM measurements and/or RLM measurements.

For example, the second association relationship may include an association relationship between an antenna polarization mode of the neighboring cell and a reference signal index, and the network device may perform RRM measurement of the neighboring cell according to the association relationship by configuring the association relationship between the antenna polarization mode of the neighboring cell and the reference signal index.

In some embodiments of the application, the QCL relationship of the first reference signal and the second reference signal is determined from a second QCL relationship, wherein the second QCL relationship is used to characterize the QCL relationship of BWP ID and reference signal index.

In some embodiments, the QCL relationships in the second QCL relationship may represent:

That is, the terminal device may determine that all reference signals on one BWP correspond to the same reference signal according to the second QCL relationship; alternatively, it is determined that the reference signals corresponding to one BWP all correspond to the same reference signal.

In some embodiments of the application, the second QCL relationship is predefined or configured by the network device.

For example, the network device configures the second QCL relationship through at least one of system messages, RRC signaling, MAC CEs, and DCIs.

In some embodiments, the second QCL relationship may be included in fifth configuration information. Alternatively, the fifth configuration information may be any configuration information that is sent by the network device to the terminal device, for example, BWP configuration information, band configuration information, and the like.

Alternatively, the fifth configuration information may be transmitted through at least one of a system message, RRC signaling, MAC CE, and DCI.

In some embodiments of the present application, the second reference signal is used as the QCL reference signal of the first reference signal, which may refer to a large scale parameter and/or an antenna polarization mode of the second reference signal may be used as the QCL reference of the first reference signal.

In the embodiment of the present application, the QCL type corresponding to the QCL relationship between the second reference signal and the first reference signal may be predefined or configured by the network device, for example, the network device may indicate through at least one of a system message, RRC signaling, MAC CE, and DCI.

It should be appreciated that in some embodiments of the present application, if the antenna polarization modes corresponding to the first reference signal and the second reference signal are different, the first reference signal and the second reference signal do not have a QCL relationship. The antenna polarization modes corresponding to the first reference signal and the second reference signal may be configured by the network device, or may be predefined, or determined according to other preset rules.

In some embodiments, if the antenna polarization modes corresponding to the first reference signal and the second reference signal are different, the terminal device does not expect the network device to configure the two reference signals as reference signals having a QCL relationship.

A specific implementation of an embodiment of the present application is described below in conjunction with the specific example shown in fig. 4.

In this example, the second reference signal is SSB on the initial BWP, and the first reference signal includes TRS on the first BWP, DMRS for PDCCH, DMRS for PDSCH.

As shown in fig. 4, in the first QCL relationship or the second QCL relationship, ssb#0 on DL bwp#0 and the reference signal on DL bwp#1 have a QCL relationship, ssb#1 on DL bwp#0 and the reference signal on DL bwp#2 have a QCL relationship, and ssb#2 on DL bwp#0 and the reference signal on DL bwp#3 have a QCL relationship. The QCL type between the reference signals may be any of the foregoing embodiments, and is exemplified by 'QCL-type a' + 'QCL-type'.

If the terminal device selects ssb#1 in the initial access procedure, the network device configures DL bwp#2 for data transmission in a connected state after the terminal device accesses the network, and accordingly, the terminal device may determine that the reference signal of DL bwp#2 satisfies the QCL relationship with ssb#1 on DL bwp#0. If the terminal device receives PDSCH2 reception scheduled by the network device on DL bwp#2, as shown in fig. 4, the terminal device may acquire the doppler shift, doppler spread, average delay, delay spread, and antenna polarization pattern of the channel from ssb#1 to adjust the filtering parameters of the DMRS channel estimator of PDSCH2, assuming that the QCL relationship is 'QCL-TypeA' + 'QCL-TypeE', according to the QCL relationship of ssb#1 and the DMRS of PDSCH2, thereby performing reception of PDSCH 2.

In summary, the terminal device may determine an antenna polarization mode corresponding to the physical channel or the reference signal transmission on the non-initial BWP according to the antenna polarization mode corresponding to the physical channel or the reference signal transmission on the initial BWP, or determine an antenna polarization mode corresponding to the physical channel or the reference signal on the non-initial BWP according to the QCL type configuration information or the first association relationship, or determine an antenna polarization mode corresponding to the physical channel or the reference signal on the non-initial BWP according to the second association relationship and the first QCL relationship, which is beneficial to avoid the problem that the antenna polarization modes of the terminal device and the network device are not matched to affect the receiving performance.

In addition, the terminal device determines that the reference signal on the initial BWP and the reference signal on the non-initial BWP have the QCL relationship, which is beneficial to avoid the problem of low resource configuration efficiency caused by configuring the QCL relationship through the network device.
