Description

Information processing method and device, communication equipment and storage medium Technical Field

[0001] The present disclosure relates to the field of wireless communication technologies but is not limited to the field of wireless communication technologies, and in particular to an information processing method and apparatus, a communication device, and a storage medium. Background Art

[0002] In related technologies, to achieve simultaneous uplink transmission to multiple transmission reception points (TRPs) using multiple antenna panels in a terminal, it is necessary to report the beam's User Equipment Capability Value Set (UECV) index (UEC) for the network, such as a base station, to select the antenna panel that the terminal should use for simultaneous uplink transmission. However, this solution only works when different antenna panels correspond to different UECVs, and cannot accurately distinguish between antenna panels with the same UECV.

[0003] Therefore, in the related art, the network side cannot accurately select uplink beams from different antenna panels that are suitable for simultaneous uplink transmission for the terminal.

[0034] Please refer to Figure 1, which shows a schematic diagram of the structure of a wireless communication system provided by an embodiment of the present disclosure. As shown in Figure 1, the wireless communication system is a communication system based on cellular mobile communication technology, and the wireless communication system may include: a plurality of terminals 11 and a plurality of access devices 12.

[0035] The terminal 11 may be a device that provides voice and / or data connectivity to a user. The terminal 11 may communicate with one or more core networks via a radio access network (RAN). The terminal 11 may be an IoT terminal, such as a sensor device, a mobile phone (or "cellular" phone), and a computer with an IoT terminal. For example, the terminal 11 may be a fixed, portable, pocket-sized, handheld, computer-built-in, or vehicle-mounted device. For example, a station (STA), subscriber unit, subscriber station, mobile station, mobile, remote station, access point, remote terminal, access terminal, user terminal, user agent, user device, or user equipment (terminal).

Alternatively, the terminal 11 may also be a roadside device, for example, a street lamp, a traffic light or other roadside device with a wireless communication function.

[0036] The access device 12 may be a network-side device in a wireless communication system. The wireless communication system may be a fourth generation mobile communication technology (4G) system, also known as a long term evolution (LTE) system; or, the wireless communication system may be a 5G system, also known as a new radio (NR) system or a 5G NR system. Alternatively, the wireless communication system may be a next generation system of the 5G system. The access network in the 5G system may be referred to as NG-RAN (New Generation-Radio Access Network). Alternatively, an MTC system.

[0037] Among them, the access device 12 can be an evolved access device (eNB) adopted in a 4G system. Alternatively, the access device 12 can also be an access device (gNB) that adopts a centralized distributed architecture in a 5G system. When the access device 12 adopts a centralized distributed architecture, it usually includes a centralized unit (CU) and at least two distributed units (DU).

The embodiment of the present disclosure does not limit the specific implementation method of the access device 12.

[0038] A wireless connection can be established between the access device 12 and the terminal 11 via a wireless air interface. In different implementations, the wireless air interface is a wireless air interface based on the fourth generation mobile communication network technology (4G) standard; or, the wireless air interface is a wireless air interface based on the fifth generation mobile communication network technology (5G) standard, for example, the wireless air interface is a new air interface; or, the wireless air interface can also be a wireless air interface based on the next generation mobile communication network technology standard of 5G.

Alternatively, the network management device may also be other core network devices, such as a serving gateway (SGW), a public data network gateway (PGW), a policy and charging rules function (PCRF), or a home subscriber server (HSS). The embodiments of the present disclosure do not limit the implementation form of the network management device 13.

[0040] As shown in FIG2 , an embodiment of the present disclosure provides an information processing method, which is executed by a terminal. The method may include:

[0041] S110: Report the transmission type corresponding to at least two beams and / or at least one beam pair configured based on the beam grouping; the transmission type is used to determine multiple uplink transmission beams of the terminal.

[0042] In the disclosed embodiments, a terminal may be a user equipment (UE), such as a mobile phone, a computer, or other device with communication capabilities. Beams configured based on beam grouping may be beams for which grouping-based beam measurement and reporting is supported by a communication protocol, such as beam grouping configured based on different beams or different antenna panels corresponding to different beams. Beams configured based on beam grouping may exist in the form of beam pairs, each beam pair comprising two beams. For example, a terminal may simultaneously report the transmission type corresponding to at least one beam pair configured based on beam grouping.

[0043] Among them, when group-based beam reporting (groupBasedBeamReporting) is set to "Enabled" in the channel state information reporting configuration (CSI-reportconfig), the transmission type corresponding to the beam based on the beam grouping configuration can be reported.

[0044] In related technologies, multiple antenna panels on a terminal are used to achieve simultaneous multi-beam transmission toward multiple transceiver points, thereby improving transmission reliability and throughput, and effectively reducing transmission delays toward multiple transceiver points.

[0045] As shown in Figure 3A , the physical uplink shared channel (PUSCH) transmission can be based on a single physical downlink control channel (PDCCH), i.e., single-downlink control information (S-DCI) scheduling for multiple antenna panels and multiple transceiver points. Alternatively, as shown in Figure 3B , it can be based on different PDCCHs, i.e., multi-downlink control information (M-DCI) scheduling for multiple antenna panels and multiple transceiver points.

[0046] Here, multi-antenna panel and multi-transceiver point transmission based on S-DCI scheduling can be based on different Transmitted Precoding Matrix Indicators (TPMIs), with one or more layers of a codeword being sent through different antenna panels. For example, antenna panel 1 and antenna panel 2 send one or more layers to corresponding transceiver points 1 and 2 based on TPMI1 and TPMI2, respectively.

[0047] Multi-antenna panel and multi-transceiver point transmission based on M-DCI scheduling can be the transmission of different PUSCHs based on different PDCCH instructions. For example, antenna panel 1 and antenna panel 2 transmit PUSCH1 and PUSCH2 to corresponding transceiver points 1 and 2 respectively based on PDCCH1 and PDCCH2.

[0048] In one embodiment, the terminal may use beam management, such as beam measurement and reporting, to allow the base station to select and indicate the beam or antenna panel for simultaneous multi-beam uplink transmission. For example, beam measurement may include: the terminal receives multiple channel state information reference signal (CSI-RS) resources or multiple synchronization signal block (SSB) resources indicated by the base station through a transmission configuration indication (TCI), etc., measures all CSI-RS resources or SSB resources, and determines the CSI-RS resource indicator (CRI) or SSB resource indicator (SSBRI) that is most suitable for simultaneous uplink transmission.

[0049] In one embodiment, after receiving at least two uplink transmit beams for uplink simultaneous transmission indicated by the base station based on the transmission type, the terminal can perform multi-beam uplink simultaneous transmission based on at least two antenna panels corresponding to the beams. For example, the base station updates the D-type quasi-co-location resource reference signal (Quasi-CoLocation TypeD source RS, QCL TypeD source RS) in the uplink TCI state (Uplink TCI state, UL TCI state) based on the CSI-RS corresponding to the CRI determined by the terminal or the SSB corresponding to the SSBRI. The terminal can perform uplink simultaneous transmission by receiving the antenna panel to which the QCL TypeD source RS is sent by the base station.

[0050] In one embodiment, the transmission type corresponding to a beam may be the type of transmission function supported by the beam. For example, the transmission type may include support for simultaneous downlink transmission and / or support for simultaneous uplink transmission. The beam reported in the measurement supports simultaneous downlink transmission, and whether it supports simultaneous uplink transmission may include support for simultaneous uplink transmission, such as support for only uplink time-sharing transmission, or support for simultaneous uplink transmission via multiple antenna panels.

[0051] In one embodiment, the beam pair may be two beams that exist in pairs based on the beam grouping configuration, wherein the transmission type corresponding to the beam pair may be the transmission type corresponding to each of the two beams in the beam pair, or may be the transmission type supported between the two beams when the two beams in the beam pair exist in pairs.

[0052] For example, a beam pair includes a first beam and a second beam. When the transmission type corresponding to the beam pair is to support simultaneous uplink transmission, it can indicate that the first beam supports simultaneous uplink transmission with other beams, and the second beam supports simultaneous uplink transmission with other beams. Alternatively, it can also indicate that the first beam and the second beam in the beam pair are supported as uplink transmission beams for simultaneous uplink transmission.

[0053] In one embodiment, reporting the transmission type corresponding to at least two beams based on the beam grouping configuration may include: reporting the transmission type corresponding to at least two beams based on the beam grouping configuration through CSI, or reporting the transmission type corresponding to at least two beams based on the beam grouping configuration through separate signaling.

[0054] In one embodiment, when reporting the transmission type corresponding to a beam pair configured based on beam grouping, the transmission types corresponding to the two beams in the beam pair may be reported separately and independently.

[0055] In one embodiment, when reporting the transmission types corresponding to multiple beam pairs configured based on beam grouping, the transmission types corresponding to the multiple beams in the multiple beam pairs may be reported sequentially, and the reporting order may indicate the beams included in the beam pair. For example, from the moment the transmission types corresponding to the beam pairs are reported, every two adjacent beams in the reporting order constitute a beam pair.

[0056] In one embodiment, reporting the transmission type corresponding to a beam pair based on the beam grouping configuration can be reporting a message containing the transmission type of two beams in a beam pair, or can be reporting the transmission type of the two beams in a beam pair independently, for example, reporting two messages containing the transmission type of one beam in the beam pair in succession.

[0057] In one embodiment, the transmission type may be indicated by a type identifier or type information. For example, the type identifier may be an identifier that corresponds to the transmission type, and different transmission types may have different corresponding type identifiers. Exemplarily, the type identifier may be an identifier composed of letters and / or numbers, or an identifier composed of one or more bits.

[0058] In one embodiment, the type information may mark the transmission type. For example, the type information may record keywords of transmission functions supported and / or not supported by the transmission type. The transmission functions may include simultaneous downlink transmission and / or simultaneous uplink transmission, and the transmission type indicates the transmission functions supported and / or not supported by the beam.

[0059] In this way, by reporting the transmission type corresponding to the beam and / or beam pair, the base station can be indicated which beam transmission functions are supported and / or not supported by multiple beams, thereby improving the ability to distinguish between different beams and antenna panels corresponding to different beams based on the transmission type, which is conducive to more accurate selection of the uplink transmission beam for the terminal to perform simultaneous uplink transmission among multiple beams.

[0060] As shown in FIG4 , an embodiment of the present disclosure provides an information processing method, which is executed by a terminal. The method may include:

[0061] S120: When reporting beam information of a beam configured based on beam grouping, report a type identifier indicating a transmission type corresponding to at least two beams; the transmission type is used to determine multiple uplink transmission beams of the terminal.

[0062] In an embodiment of the present disclosure, reporting beam information of a beam configured based on beam grouping may be reporting beam information of the beam after completing downlink beam measurement and beam grouping configuration. The beam information may include at least one of the following: a CRI corresponding to the beam, an SSBRI corresponding to the beam, a Layer 1 Reference Signal Receiving Power (L1-RSRP) corresponding to the beam, a Layer 1 Signal to Interference plus Noise Ratio (L1-SINR) corresponding to the beam, and a terminal capability value set index of the antenna panel corresponding to the beam.

[0063] Here, the beam information may include one of the CRI and SSBRI. For example, if the terminal performs downlink beam measurement based on the received CSI-RS, the beam information may include the CRI corresponding to the CSI-RS. If the terminal performs downlink beam measurement based on the received SSB, the beam information may include the SSBRI corresponding to the SSB.

[0064] In one embodiment, the terminal capability value set index in the beam information can be an index value indicating the capability type of the antenna panel corresponding to the beam, and different index values ​​can correspond to different capability types. For example, the terminal has two panels, panel#0 and panel#1, and the maximum number of supported sounding reference signal (SRS) ports is 4 and 2, respectively. The terminal capability value set UE capability value set can be defined as {4, 2}, and the terminal capability value set index corresponding to panel#0 is UE capability value set index#0, indicating that the maximum number of SRS ports is 4, and the terminal capability value set index corresponding to panel#1 is UE capability value set index#1, indicating that the maximum number of SRS ports is 2. Among them, the terminal capability value set index can also be simplified as cap_index1, indicating that the capability type of the antenna panel corresponding to the beam is the first category.

[0065] In one embodiment, when reporting beam information of beams configured based on beam grouping, reporting type identifiers indicating the transmission types corresponding to at least two beams may mean reporting type identifiers indicating the transmission types corresponding to at least two beams when independently reporting beam information of at least two beams configured based on beam grouping. For example, when reporting beam information of a first beam, the type identifier of the transmission type corresponding to the first beam is reported; when reporting beam information of a second beam, the type identifier of the transmission type corresponding to the second beam is reported.

[0066] Here, the type identifier can indicate the transmission type corresponding to a beam, and the beam and the type identifier have a corresponding relationship.

[0067] In one embodiment, the type identifier may be an identifier corresponding to the transmission type, and different transmission types may have different corresponding type identifiers. For example, the type identifier may be an identifier composed of letters and / or numbers, or an identifier composed of one or more bits.

[0068] In one embodiment, the beam information of the beam can be reported through CSI, and the type identifier of the transmission type corresponding to the beam can also be reported through the same CSI.

[0069] In this way, reporting the type identifier of the transmission type corresponding to the beam at the same time as reporting the beam information can improve the efficiency of beam reporting and facilitate more accurate determination of the uplink transmission beam for the terminal to perform uplink simultaneous transmission based on the beam information and transmission type of the beam.

[0070] In some embodiments, the transmission type includes one of the following:

[0071] Supports simultaneous downlink transmission but not uplink transmission;

[0072] Supports simultaneous downlink transmission and supports uplink transmission in addition to simultaneous uplink transmission;

[0073] Supports simultaneous downlink transmission and simultaneous uplink transmission through different antenna panels.

[0074] In the embodiment of the present disclosure, simultaneous downlink transmission is supported but uplink transmission is not supported, which may represent a downlink (DL-only) beam, or a downlink beam implemented by an antenna panel (DL-only panel) that only supports downlink beams.

[0075] In one embodiment, supporting simultaneous downlink transmission and supporting uplink transmission in addition to simultaneous uplink transmission may indicate that simultaneous downlink transmission and uplink transmission are supported, but different uplink transmission beams do not support simultaneous transmission. For example, only time-division multiplexing (TDM)-based time-sharing transmission of uplink beams is supported. Different uplink beams may correspond to the same antenna panel.

[0076] In one embodiment, supporting simultaneous downlink transmission and supporting simultaneous uplink transmission through different antenna panels may mean supporting simultaneous downlink transmission and simultaneous uplink transmission, and different uplink beams correspond to different antenna panels.

[0077] In some embodiments, the type identification includes:

[0078] Two bits indicating the transmission type; wherein the two bits are used to jointly indicate the transmission type, or the two bits are used to indicate different transmission types respectively.

[0079] In the embodiment of the present disclosure, the type identifier may include two bits, each of which may be 0 or 1. When the two bits are used to jointly indicate the transmission type, the value of the two bits corresponds to the transmission type, and different values ​​of the two bits correspond to different transmission types.

[0080] In one embodiment, when the two bits are 00, it can represent the first transmission type, for example, supporting simultaneous downlink transmission and not supporting uplink transmission; when the two bits are 01, it can represent the second transmission type, for example, supporting simultaneous downlink transmission and not supporting simultaneous uplink transmission; when the two bits are 10, it can represent the third transmission type, for example, supporting simultaneous downlink transmission and supporting simultaneous uplink transmission through different antenna panels.

[0081] In one embodiment, when two bits are used to indicate different transmission types, different values ​​of each bit correspond to the transmission type, for example, different values ​​of each bit correspond to different transmission types.

[0082] In one embodiment, the first bit of the two bits may indicate whether the first transmission type is supported, that is, whether a DL-only beam is included. For example, a first bit value of 0 indicates that a DL-only beam is not included, and a first bit value of 1 indicates that a DL-only beam is included. The second bit may indicate whether a second transmission type or a third transmission type is supported, that is, whether simultaneous uplink transmission of different panels is supported. For example, a second bit value of 0 indicates support for the second transmission type, and a second bit value of 1 indicates support for the third transmission type, etc.

[0083] As shown in FIG5 , an embodiment of the present disclosure provides an information processing method, which is executed by a terminal. The method may include:

[0084] S130: When reporting beam information of a beam in at least one beam pair configured based on beam grouping, report a type identifier indicating a transmission type corresponding to the at least one beam pair.

[0085] In the disclosed embodiments, the reported type identifier may indicate the transmission type corresponding to a beam pair, or multiple type identifiers may indicate the transmission types corresponding to multiple beam pairs. The beam pair may be determined based on the beam grouping configuration, for example, the first beam and the second beam may form a beam pair, the third beam and the fourth beam may form a beam pair, and so on.

[0086] In one embodiment, the type identifier indicating the transmission type corresponding to a beam pair can indicate the transmission type supported between the two beams included in the beam pair. For example, a beam pair corresponds to a type identifier, and the type identifier can indicate whether the two beams in the beam pair support simultaneous downlink transmission and whether they support simultaneous uplink transmission, etc.

[0087] For example, a beam pair includes a first beam and a second beam. When the transmission type corresponding to the beam pair is supporting simultaneous uplink transmission, it can be indicated that the first beam and the second beam in the beam pair are supported as uplink transmission beams for simultaneous uplink transmission.

[0088] In one embodiment, the type identifier of the transmission type corresponding to a beam pair based on the beam grouping configuration is reported. It can be reported together with the beam information of a beam in the beam pair, or the type identifier corresponding to the beam pair can be reported when the beam information of the two beams in the beam pair is reported independently.

[0089] In this way, by reporting one or more beam pairs, the flexibility of uplink beam transmission scheduling can be improved. In addition, the type identifier corresponding to the beam pair can more accurately and efficiently indicate whether the two beams in a beam pair support simultaneous uplink transmission, thereby facilitating faster determination of the terminal's uplink transmission beam.

[0090] In some embodiments, the transmission type is:

[0091] Supports simultaneous downlink transmission and supports uplink transmission in addition to simultaneous uplink transmission;

[0092] or,

[0093] Supports simultaneous downlink transmission and simultaneous uplink transmission through different antenna panels.

[0094] In some embodiments, the transmission type is:

[0095] Supports simultaneous downlink transmission but not uplink transmission;

[0096] or,

[0097] Supports simultaneous downlink transmission and simultaneous uplink transmission through different antenna panels.

[0098] In the disclosed embodiments, the transmission type corresponding to a beam pair may indicate the supported and / or unsupported transmission modes between the two beams in the beam pair. For example, if the transmission type corresponding to the beam pair indicates support for simultaneous uplink transmission, then both beams in the beam pair may be used as uplink transmit beams for simultaneous transmission.

[0099] In some embodiments, the type identification includes:

[0100] A single bit indicating the transfer type.

[0101] In an embodiment of the present disclosure, the type identifier corresponding to a beam pair may include a bit, and the bit values ​​0 and 1 respectively indicate different transmission types. For example, the bit values ​​0 and 1 may respectively indicate the two transmission types in the aforementioned embodiment, or may be directly used to indicate whether the beam pair supports simultaneous uplink transmission.

[0102] For example, the transmission type supports simultaneous downlink transmission but not uplink transmission, or supports simultaneous downlink transmission and simultaneous uplink transmission through different antenna panels. When the value of the bit is 0, it can indicate that the two beams in the beam pair support simultaneous downlink transmission but do not support uplink transmission, that is, the two beams in the beam pair cannot be used as uplink transmission beams. When the value of the bit is 1, it can indicate that the two beams in the beam pair support simultaneous downlink transmission and support simultaneous uplink transmission through different antenna panels, that is, the two beams in the beam pair can be used as uplink transmission beams for simultaneous transmission.

[0103] For example, the transmission type is to support simultaneous downlink transmission and support uplink transmission in addition to simultaneous uplink transmission, or to support simultaneous downlink transmission and support simultaneous uplink transmission through different antenna panels. When the value of the bit is 0, it can indicate that the two beams in the beam pair support simultaneous downlink transmission and support uplink transmission in addition to simultaneous uplink transmission, that is, the two beams in the beam pair cannot simultaneously transmit uplink. When the value of the bit is 1, it indicates that the two beams in the beam pair support simultaneous downlink transmission and support simultaneous uplink transmission through different antenna panels, that is, the two beams in the beam pair can be used as uplink transmission beams for simultaneous transmission.

[0104] In some embodiments, beam information and type identification are reported via channel state information CSI used for beam management.

[0105] Here, when reporting CSI, the CSI measurement result, beam information and type identifier corresponding to the beam can be reported through one signaling.

[0106] In some embodiments, the CSI reporting method includes: periodic reporting, aperiodic reporting, or semi-persistent reporting.

[0107] In the disclosed embodiments, periodic reporting (P-CSI) may be performed by indicating a reporting period by a base station or presetting a reporting period according to a protocol, and performing CSI reporting at a reporting time corresponding to the reporting period. Aperiodic reporting (AP-CSI) may be performed by responding to a reporting instruction from a base station. Semi-persistent reporting (SP-CSI) may be a reporting process in which periodic reporting is initiated in response to a reporting instruction from a base station and stopped in response to a stop reporting instruction from the base station.

[0108] In some embodiments, the beam information includes at least one of the following:

[0109] CRI;

[0110] SSBRI;

[0111] L1-RSRP;

[0112] L1-SINR;

[0113] The terminal capability value set index of the antenna panel corresponding to the beam.

[0114] In some embodiments, the beam information and type identifier are used to schedule uplink transmission based on the S-DCI;

[0115] or,

[0116] Beam information and type identifier are used to schedule uplink transmission based on M-DCI.

[0117] In the disclosed embodiments, multi-antenna panel and multi-TRP transmission based on S-DCI scheduling can be based on different broadband precoding matrix indicators (TPMIs), with one or more layers of a codeword being sent through different antenna panels. For example, antenna panel 1 and antenna panel 2 send one or more layers to corresponding TRP1 and TRP2 based on TPMI1 and TPMI2, respectively.

[0118] Multi-antenna panel and multi-TRP transmission based on M-DCI scheduling can be based on different PUSCH transmissions indicated by different PDCCHs. For example, antenna panel 1 and antenna panel 2 transmit PUSCH1 and PUSCH2 to corresponding TRP1 and TRP2 based on PDCCH1 and PDCCH2 respectively.

[0119] As shown in FIG6 , an embodiment of the present disclosure provides an information processing method, which is executed by a base station. The method may include:

[0120] S210: Determine multiple uplink transmission beams of the terminal based on the transmission type corresponding to at least two beams and / or at least one beam pair configured based on beam grouping reported by the terminal.

[0121] In the embodiments of the present disclosure, the transmission type corresponding to a beam may be the type of transmission function supported by the beam. For example, the transmission type may include support for simultaneous downlink transmission and / or support for simultaneous uplink transmission. Specifically, the measurement reporting beam supports simultaneous downlink transmission, and whether it supports simultaneous uplink transmission may include support for simultaneous uplink transmission, such as support for only uplink time-sharing transmission, or support for simultaneous uplink transmission via multiple antenna panels.

[0122] In one embodiment, the beam pair may be two beams that exist in pairs based on the beam grouping configuration, wherein the transmission type corresponding to the beam pair may be the transmission type corresponding to each of the two beams in the beam pair, or may be the transmission type supported between the two beams when the two beams in the beam pair exist in pairs.

[0123] For example, a beam pair includes a first beam and a second beam. The transmission type corresponding to the beam pair may indicate that the first beam supports simultaneous uplink transmission with other beams, and that the second beam supports simultaneous uplink transmission with other beams, or it may indicate simultaneous uplink transmission of the first beam and the second beam in the beam pair.

[0124] In one embodiment, the transmission type corresponding to at least two beams based on the beam grouping configuration reported by the terminal may include: the transmission type corresponding to at least two beams based on the beam grouping configuration reported by the terminal through CSI, or it may also be the transmission type corresponding to at least two beams based on the beam grouping configuration reported through separate signaling.

[0125] In one embodiment, when reporting the transmission type corresponding to a beam pair configured based on beam grouping, the transmission types corresponding to the two beams in the beam pair may be reported separately and independently.

[0126] In one embodiment, the transmission types corresponding to multiple beam pairs configured based on beam grouping reported by the base station may be received sequentially, and the reporting order may indicate the beams included in the beam pair. For example, from the moment the transmission type corresponding to the beam pair is reported at the beginning of the current cycle, every two adjacent beams in the reporting order constitute a beam pair.

[0127] In one embodiment, the transmission type corresponding to at least two beams configured based on the beam grouping may be a message containing the transmission type of two beams in a beam pair reported by the received terminal, or the transmission type of the two beams in a beam pair may be reported independently, for example, two messages containing the transmission type of a beam in a beam pair received successively.

[0128] In one embodiment, the transmission type may be indicated by a type identifier or type information. For example, the type identifier may be an identifier that corresponds to the transmission type, and different transmission types may have different corresponding type identifiers. Exemplarily, the type identifier may be an identifier composed of letters and / or numbers, or an identifier composed of one or more bits.

[0129] In one embodiment, the type information may mark the transmission type. For example, the type information may record keywords of transmission functions supported and / or not supported by the transmission type. The transmission functions may include simultaneous downlink transmission and / or simultaneous uplink transmission, and the transmission type indicates the transmission functions supported and / or not supported by the beam.

[0130] In one embodiment, based on the transmission type corresponding to at least two beams based on the beam grouping configuration reported by the terminal, multiple uplink transmission beams of the terminal are determined. The transmission type may be based on the transmission type corresponding to at least two beams based on the beam grouping configuration reported by the terminal. The transmission type is determined to include supporting beams that simultaneously transmit uplinks through different antenna panels as uplink transmission beams of the terminal.

[0131] For example, it may include: based on the transmission type and beam information corresponding to at least two beams configured based on beam grouping reported by the terminal, among the transmission types including multiple beams supporting simultaneous uplink transmission through different antenna panels, selecting multiple beams with the best L1-RSRP or L1-SINR indicated by the beam information as the uplink transmission beams of the terminal.

[0132] In this way, by receiving the transmission type corresponding to the beam and / or beam pair reported by the terminal, the beam transmission functions supported and / or not supported by multiple beams can be determined, thereby improving the ability to distinguish between different beams and antenna panels corresponding to different beams based on the transmission type, which is conducive to more accurately selecting the uplink transmission beam for the terminal to perform uplink simultaneous transmission among multiple beams.

[0133] In some embodiments, as shown in FIG7 , S210 may include:

[0134] S211: Determine, based on the type identifier reported by the terminal, the transmission type corresponding to at least two beams configured based on the beam grouping reported by the terminal;

[0135] S212: Determine multiple uplink transmission beams of the terminal based on the transmission type.

[0136] In one embodiment, the base station may simultaneously receive a beam type identifier and beam information of the beam. The beam information may include at least one of the following: a CRI corresponding to the beam, an SSBRI corresponding to the beam, an L1-RSRP corresponding to the beam, an L1-SINR corresponding to the beam, and an index of a terminal capability value set of an antenna panel corresponding to the beam.

[0137] Here, the beam information may include one of the CRI and SSBRI. For example, if the terminal performs downlink beam measurement based on the received CSI-RS, the beam information may include the CRI corresponding to the CSI-RS. If the terminal performs downlink beam measurement based on the received SSB, the beam information may include the SSBRI corresponding to the SSB.

[0138] Here, the type identifier can indicate the transmission type corresponding to a beam, and the beam and the type identifier have a corresponding relationship.

[0139] In one embodiment, the type identifier may be an identifier corresponding to the transmission type, and different transmission types may have different corresponding type identifiers. For example, the type identifier may be an identifier composed of letters and / or numbers, or an identifier composed of one or more bits.

[0140] In one embodiment, the base station may receive beam information of the beam through the CSI reported by the terminal, and the type identifier of the transmission type corresponding to the beam may also be received through the same CSI.

[0141] In one embodiment, the terminal capability value set index in the beam information may indicate the capability type of the antenna panel corresponding to the beam through an index value, and different index values ​​may correspond to different capability types. For example, the terminal capability value set index may be represented as cap_index1, indicating that the capability type of the antenna panel corresponding to the beam is the first type.

[0142] In some embodiments, the transmission type includes one of the following:

[0143] Supports simultaneous downlink transmission but not uplink transmission;

[0144] Supports simultaneous downlink transmission and supports uplink transmission in addition to simultaneous uplink transmission;

[0145] Supports simultaneous downlink transmission and simultaneous uplink transmission through different antenna panels.

[0146] In some embodiments, the type identification includes:

[0147] Two bits indicating the transmission type; wherein the two bits are used to jointly indicate the transmission type, or the two bits are used to indicate different transmission types respectively.

[0148] In the embodiment of the present disclosure, the type identifier may include two bits, each of which may be 0 or 1. When the two bits are used to jointly indicate the transmission type, the value of the two bits corresponds to the transmission type, and different values ​​of the two bits correspond to different transmission types.

[0149] In one embodiment, when the two bits are 00, it can represent the first transmission type, for example, supporting simultaneous downlink transmission and not supporting uplink transmission; when the two bits are 01, it can represent the second transmission type, for example, supporting simultaneous downlink transmission and not supporting simultaneous uplink transmission; when the two bits are 10, it can represent the third transmission type, for example, supporting simultaneous downlink transmission and supporting simultaneous uplink transmission through different antenna panels.

[0150] In one embodiment, when two bits are used to indicate different transmission types, different values ​​of each bit correspond to the transmission type, for example, different values ​​of each bit correspond to different transmission types.

[0151] In one embodiment, the first bit of the two bits may indicate whether the first transmission type is supported, that is, whether a DL-only beam is included. For example, a first bit value of 0 indicates that a DL-only beam is not included, and a first bit value of 1 indicates that a DL-only beam is included. The second bit may indicate whether a second transmission type or a third transmission type is supported, that is, whether simultaneous uplink transmission of different panels is supported. For example, a second bit value of 0 indicates support for the second transmission type, and a second bit value of 1 indicates support for the third transmission type, etc.

[0152] In some embodiments, S211 may include:

[0153] Determining, based on the type identifier reported by the terminal, a transmission type corresponding to at least one beam pair configured based on the beam grouping reported by the terminal;

[0154] Multiple uplink transmission beams of the terminal are determined based on the transmission type.

[0155] In the disclosed embodiments, a terminal may report a type identifier for a transmission type corresponding to a beam pair, or multiple type identifiers for transmission types corresponding to multiple beam pairs. The beam pair may be determined based on a beam grouping configuration, for example, the first beam and the second beam may form a beam pair, the third beam and the fourth beam may form a beam pair, and so on.

[0156] In one embodiment, the type identifier corresponding to a beam pair can indicate the transmission type supported between the two beams contained in the beam pair. For example, a beam pair corresponds to a type identifier, and the type identifier indicates whether the two beams in the beam pair support simultaneous downlink transmission and whether they support simultaneous uplink transmission, etc.

[0157] In this way, by reporting one or more beam pairs, the flexibility of uplink beam transmission scheduling can be improved. In addition, the type identifier corresponding to the beam pair can more accurately and efficiently indicate whether the two beams in a beam pair support simultaneous uplink transmission, thereby facilitating faster determination of the terminal's uplink transmission beam.

[0158] In some embodiments, the transmission type is:

[0159] Supports simultaneous downlink transmission and supports uplink transmission in addition to simultaneous uplink transmission;

[0160] or,

[0161] Supports simultaneous downlink transmission and simultaneous uplink transmission through different antenna panels.

[0162] In some embodiments, the transmission type is:

[0163] Supports simultaneous downlink transmission but not uplink transmission;

[0164] or,

[0165] Supports simultaneous downlink transmission and simultaneous uplink transmission through different antenna panels.

[0166] In some embodiments, the type identification includes:

[0167] A single bit indicating the transfer type.

[0168] In the embodiment of the present disclosure, the type identifier corresponding to a beam pair may include a bit, and the bit values ​​0 and 1 respectively indicate different transmission types. For example, the bit values ​​0 and 1 may respectively indicate the two transmission types in the aforementioned embodiment, or may be directly used to indicate whether the beam pair supports simultaneous uplink transmission. For example, when the bit value is 0, it indicates that the two beams in the beam pair support simultaneous downlink transmission but do not support simultaneous uplink transmission. When the bit value is 1, it indicates that the two beams in the beam pair support simultaneous downlink transmission and support simultaneous uplink transmission through different antenna panels.

[0169] In some embodiments, determining multiple uplink transmit beams of a terminal based on a transmission type includes:

[0170] If the transmission type supports simultaneous downlink transmission and simultaneous uplink transmission through different antenna panels, multiple uplink transmission beams of the terminal are determined based on the beams corresponding to the transmission type.

[0171] Here, for a beam whose transmission type supports simultaneous uplink transmission through different antenna panels, it can be determined as the uplink transmission beam of the terminal.

[0172] In one embodiment, if the transmission type supports simultaneous downlink transmission and supports simultaneous uplink transmission through different antenna panels, then multiple uplink transmission beams of the terminal are determined based on the beam corresponding to the transmission type, which may include: if the transmission type supports simultaneous downlink transmission and supports simultaneous uplink transmission through different antenna panels, then in the beam corresponding to the transmission type, multiple uplink transmission beams of the terminal are determined based on the beam information.

[0173] For example, based on the beam information, multiple uplink transmission beams of the terminal are determined, and multiple beams with optimal L1-RSRP or L1-SINR indicated by the beam information can be selected as the uplink transmission beams of the terminal.

[0174] The embodiments of the present disclosure provide a solution for enhancing beam reporting to support simultaneous uplink transmission based on multiple antenna panels. Specifically:

[0175] When reporting the information of each beam in the downlink beam pair, the type identifier of the transmission type corresponding to the beam pair is also reported.

[0176] Option 1:

[0177] The reported beam pairs can correspond to different transmission types:

[0178] 1) Transmission type 1: includes downlink (DL) beams implemented with DL-only beams or DL-only panels;

[0179] 2) Transmission Type 2: Supports DL and uplink (UL) transmission, but different UL beams only support TDM transmission. Different uplink beams may correspond to the same antenna panel.

[0180] 3) Transmission type 3: supports simultaneous DL and UL transmission, and different uplink beams correspond to different antenna panels.

[0181] When reporting CSI, add the type identifier indicating the transmission type of the beam pair:

[0182] In one embodiment, three situations are indicated through joint signaling, such as 2 bits.

[0183] For example, the reported beam pair information is in the form of {CRI3+L1-RSRP2+terminal capability value set index (cap_index) 0; CRI5+L1-RSRP4+cap_index0; type identifier (fuc_ID) = 1}, then the type identifier of the beam pair actually reported uniformly is 1, which can indicate support for uplink transmission of a single antenna panel;

[0184] In one embodiment, it is represented by 2 bits, the first bit indicates whether DL-Only is included, and the second bit indicates whether different antenna panels are used for transmission.

[0185] For example, the reported beam pair information is in the form of {CRI3+L1-RSRP2+cap_index0; CRI5+L1-RSRP4+cap_index0; fuc_ID=01}, and the type identifier of the beam pair actually reported uniformly is 1, indicating support for single antenna panel uplink transmission.

[0186] Option 2:

[0187] Directly indicate whether a reported beam pair capable of simultaneous downlink reception can be used for simultaneous uplink transmission. For example, reporting beam pair information {CRI3+L1-RSRP2+cap_index0; CRI5+L1-RSRP4+cap_index0; 1} indicates that the reported beam pair can support simultaneous uplink transmission on multiple antenna panels, i.e., using a single bit to indicate the corresponding transmission type for the beam pair.

[0188] In one embodiment, the maximum number of reported beams or the maximum number of beam pairs can be increased to support reporting of multiple beam pairs. For example, the number of reported beams can be configured to be N=4, that is, 2 beam pairs are reported.

[0189] For the above embodiments, enhanced measurement reporting supporting simultaneous transmission of multiple antenna panels (STxMP) can be used simultaneously for P-CSI, SP-CSI or AP-CSI, where the terminal can support P-CSI by default, and supporting SP-CSI / AP-CSI is an optional capability of the terminal.

[0190] In one embodiment, for STxMP transmission, beam measurement reporting can be used to schedule uplink S-DCI-based transmission as well as M-DCI-based transmission.
