[0002] Coordinated transmission or reception using multiple transmission and reception points (Multiple Transmission and Reception Points, Multi-TRP) is an important technology in current wireless communications, which plays a prominent role in increasing the throughput of wireless communications.

[0014] The present invention will be described in detail below based on embodiments with reference to the drawings.

[0015] In addition, the terms "first", "second", etc. in the specification and claims of the present invention and the above drawings are used to distinguish similar objects, and are not necessarily used to describe a specific order or chronology.

[0016] In order to further describe the method and apparatus for determining a spatial parameter in the present invention, the application scenario of the method and apparatus for determining a spatial parameter in the present invention will be further described below.

[0017] The method and apparatus for determining spatial parameters according to the embodiments of the present invention can be applied to various communication systems, such as a Long Term Evolution (LTE) system, LTE Time Division Duplex (TDD), LTE Advance, Universal Mobile Telecommunication System (UMTS), 5GNR (New Radio NR) communication, and systems corresponding to their evolved or developed versions.

[0018] The method and device for determining spatial parameters in an embodiment of the present invention are used in an interaction between at least one first communication node and at least one second communication node, where the first communication node may be an evolved base station (Evolutional Node B, eNB or eNodeB) in LTE, a base station device in a 5G network, or a base station in a future communication system, etc., and the base station may include various macro base stations, micro base stations, home base stations, wireless remotes, routers, location servers, or various network side devices such as primary cells and secondary cells, location management function (LMF) devices, and the second communication node may be a terminal device, and may be an access terminal, user equipment (User Equipment, UE), user unit, user station, mobile station, remote station, remote terminal, mobile device, user terminal, wireless communication device, user agent, or user equipment.

[0019] For example, the terminal device may be a mobile phone, a cordless phone, a Session Initiation Protocol (SIP) phone, a Wireless Local Loop (WLL) station, a Personal Digital Assistant (PDA), a handheld device with wireless communication capability, a computer device or other processing device connected to a wireless modem, an in-vehicle device, a wearable device, or a terminal device in a 5G network, etc. The above application scenarios are merely some of the examples, and the present invention is not limited thereto, and the first communication node and the second communication node may be collectively referred to as communication nodes.

[0020] The spatial parameter determination method provided by the embodiment of the present invention can be implemented in the first communication node and / or the second communication node. Taking the implementation in the first communication node as an example, FIG. 1 is a structural block diagram of hardware implementing the spatial parameter determination method provided by the embodiment of the present invention. As shown in FIG. 1, the first communication node 10, e.g., a base station, can include one or more (only one is shown in FIG. 1) processors 102 (the processors 102 can include, but are not limited to, processing devices such as microprocessors MCU or programmable logic devices FPGAs) and a memory 104 configured to store data, and the first communication node can further include a transmission device 106 configured to realize a communication function with the second communication node 20.

[0021] As can be appreciated by those skilled in the art, the structure shown in Figure 2 is merely exemplary, and is not intended to limit the structure of the first communication node. For example, the first communication node 10 may include more or less assemblies than those shown in Figure 1, or may have a different configuration than those shown in Figure 1.

[0022] In an embodiment of the present invention, it is necessary to configure some reference signal resources to measure Channel State Information (CSI) or obtain parameters of other functions of the channel, such as time-frequency offset, mobility management, location information, beam management, etc.

[0023] Among them, the reference signal resources include, but are not limited to, Channel State Information-Reference Signal (CSI-RS) resources, Synchronization Signals Block (SSB) resources, Physical Broadcast Channel (PBCH) resources, Synchronization Broadcast Block / Physical Broadcast Channel (SSB / PBCH) resources, uplink Sounding reference signal (SRS) resources, and Positioning Reference Signals (PRS).

[0024] The above CSI-RS resource mainly refers to a Non Zero Power Channel State Information-Reference Signal (NZP-CSI-RS) resource.

[0025] The interference measurement resources include, but are not limited to, Channel State Information-Interference Measurement (CSI-IM), NZP-CSI-RS for Interference Measurement, and Zero Power Channel State Information-Reference Signal (ZP-CSI-RS). In one interference measurement, the M1 interference measurement resources included in the interference measurement resources may include at least one of NZP-CSI-RS, CSI-IM, and ZP-CSI-RS. For these reference signals, the periodic reference signal, the semi-persistent reference signal, and the aperiodic reference signal are further included based on the set time domain characteristics, where the periodic reference signal is transmitted once per period, the semi-persistent reference signal is transmitted periodically within the time interval from activation to deactivation, and the aperiodic reference signal is transmitted only once after triggering the signaling.

[0026] For example, the periodic reference signal is at least one of periodic NZP CSI-RS, CSI-IM, ZP CSI-RS, SSB, and SRS. The aperiodic reference signal includes at least one of aperiodic NZP CSI-RS, CSI-IM, ZP CSI-RS, SSB, and SRS. The semi-persistent reference signal is at least one of semi-persistent NZP CSI-RS, CSI-IM, ZP CSI-RS, SSB, and SRS. Embodiments of the present invention may use SSB to represent SSB and / or PBCH.

[0027] For transmitting data or signaling, physical channels can be divided into physical downlink control channel (PDCCH), physical uplink control channel (PUCCH), physical downlink shared channel (PDSCH), and physical uplink shared channel (PUSCH), among which PUSCH and PDSCH are called physical shared channels, PDCCH and PUCCH are called physical control channels or control channels, PDCCH and PDSCH are physical downlink channels, and PUSCH and PUCCH are physical uplink channels.

[0028] The transmission signal described in the embodiment of the present invention includes various reference signals and various physical channels, such as at least one of NZP CSI-RS, ZP CSI-RS, SSB, SRS, PDSCH, PDCCH, PUSCH, PUCCH, CSI-IM, etc., and the reference signals may be periodic, aperiodic, or semi-persistent.

[0029] Since transmission signals having the same spatial parameters can be received or transmitted using beams corresponding to the same spatial parameters, the transmission signals having the same spatial parameters are classified into transmission signals of the same type, for example, a plurality of transmission signals are divided into N types of transmission signals, where the same type of transmission signals have the same spatial parameters and the different types of transmission signals have different spatial parameters, and N is an integer greater than 1.

[0030] The spatial parameters described in the embodiment of the present invention include at least one of the following parameters: a quasi-collocation reference signal, a quasi-collocation reference signal of related spatial reception parameters, a spatial transmission filter, a spatial relationship reference signal, and a quasi-collocation parameter.

[0031] Here, the quasi-co-location parameters include at least one of quasi-co-located (QCL), transmission configuration indicator (TCI), transmission configuration indicator state (TCI state), TCI state group, QCL Type D, receive beam group, transmit beam group, receive beam, transmit beam, and spatial receive parameter (Spatial Rx Parameter).

[0032] The beam information may include at least one of the following: angle of arrival (AOA), angle of departure (AOD), Zenith angle of departure (ZOD), Zenith angle of arrival (ZOA), Discrete Fourier Transformation (DFT) vector, codeword in a codebook, transmit beam, receive beam, transmit beam group, receive beam group, transmit beam index, receive beam index, transmit beam group index, and receive beam group index.

[0033] The above-mentioned quasi-collocated QCL may include QCL type A, QCL type B, QCL type C and QCL type D. Two ports satisfying the quasi-collocated relationship indicates that the large-scale information of one port can be derived from the large-scale information of another port, and the large-scale information includes, but is not limited to, Doppler shift, Doppler spread, average delay, delay spread, and spatial Rx parameters.

[0034] The QCL types are classified as follows:

[0035] - "QCL-TypeA": {Doppler shift, Doppler spread, average delay, delay spread} - "QCL-TypeB": {Doppler shift, Doppler spread} - "QCL-TypeC": {Doppler shift, average delay} - "QCL-TypeD": {Spatial Rx parameter}

[0036] In an embodiment of the present invention, the time domain unit is a time unit including at least one of a slot, a symbol, a slot group, a symbol group, X milliseconds, and Y microseconds, where the symbol group includes at least one symbol (e.g., a mini-timeslot) and the time slot group includes at least one time slot, where X and Y are positive real numbers.

[0037] In the embodiments of the present invention, a symbol refers to a time unit in a subframe, frame, or time slot, such as an Orthogonal Frequency Division Multiplexing (OFDM) symbol, a Single-Carrier Frequency Division Multiple Access (SC-FDMA) symbol, or an Orthogonal Frequency Division Multiple Access (OFDMA) symbol. In the embodiments of the present invention, a symbol and a time domain symbol can be interchangeable, including, but not limited to, OFDM, OFDMA, SC-FDMA, variations of these symbols, and symbols after time-domain and frequency-domain filtering of these symbols.

[0038] In addition, in the embodiments of the present invention, the index and the indicator are interchangeable concepts.

[0039] In an embodiment of the present invention, the higher layer signaling includes Radio Resource Control (RRC) signaling and / or Media Access Control control element (MAC CE) signaling, and the physical layer signaling includes Downlink Control Information (DCI) in a physical downlink control channel, or signaling fed back on a physical uplink control channel or a physical uplink shared channel.

[0040] In the embodiment of the present invention, in the case of multiple transmission / reception points or multi-panel transmission, one panel can correspond to one port group (e.g., antenna port group, antenna group), and the two correspond one-to-one and can be substituted for each other. The panel refers to an antenna panel, and each of one transmission / reception points (Transmission Reception Point, TRP) or communication nodes (including but not limited to terminals, base stations, etc.) can include at least one antenna panel.

[0041] Each panel has one or more antenna arrays, and the arrays can be virtualized into one antenna port. The antenna ports on a panel can be divided into one port group. A panel can be further divided into multiple sub-panels, and the multiple antenna ports included in each sub-panel can be divided into one port group. For example, a dual-polarized antenna has one sub-panel for an antenna with +45 degree polarization and one sub-panel for an antenna with -45 degree polarization. In the embodiments of the present application, the panel and the sub-panel are both collectively referred to as a panel and are represented as a panel, and the panel here can be replaced with a port group.

[0042] In standards such as NR, the PDCCH needs to be mapped to a set of resource elements (REs), e.g., including one or more control channel elements (CCEs), where one RE includes one subcarrier in the frequency domain and one symbol in the time domain, and one CCE includes multiple REs.

[0043] A set of one or more CCEs used to transmit a PDCCH is sometimes called a control resource set (CORESET), which includes multiple physical resource blocks in the frequency domain and K symbols in the time domain, where K is a natural number, for example, K can be an integer of 1, 2, or 3. To detect a PDCCH, candidate PDCCHs at a certain aggregation level are set into a set, and the candidate PDCCH set at this level is a search space (SS), and a set of multiple search spaces forms a search space set (SS set, SSSET, or SSS), and each terminal can be configured with at least one search space set.

[0044] In order to detect the PDCCH, the current terminal's PDCCH detection opportunity (i.e., occasion) and the detected PDCCH candidate (i.e., candidate) or PDCCH candidate are set in the search space. In addition, the PDCCH includes multiple formats, each of which corresponds to one downlink control information (DCI) in a corresponding format, and each DCI further includes multiple specific signaling indication domains. Here, the detection is also called monitoring or blind detection, and is mainly used to determine which of multiple candidate PDCCHs is the PDCCH for transmitting downlink control information to the terminal.

[0045] In the embodiments of the present invention, the transmission may refer to sending or receiving, for example, the transmission of data or a signal may refer to sending data or a signal, or may refer to receiving data or a signal, where the signal includes various reference signals, and the data includes data transmitted by a physical uplink shared channel or a physical downlink shared channel.

[0046] In an embodiment of the present invention, in order to better transmit a PUSCH or a PDSCH, a set of K1 consecutive symbols and L1 frequency domain subcarriers (REs) is formed into one resource block (RB, also called physical resource block, PRB, or RB), where K1 and L1 are positive integers, e.g., K1=12 or 14, L1=12. Here, one RE includes the minimum resource unit for carrying one modulated signal corresponding to one symbol and one subcarrier.

[0047] In order to demodulate or obtain information (including data or signals) associated with a physical channel modulated into an RE, it is necessary to estimate the value of the radio channel in the RE, which is generally estimated by a Demodulation Reference Signal (DMRS), and channel interpolation in the RE corresponding to the DMRS is used to obtain the channel in the physical channel.

[0048] In an embodiment of the present invention, a Radio Network Temporary Identifier (RNTI) is used to make the contents of signal information between a first communication node and a second communication node an identifier of the second communication node, mainly including at least one of SI-RNTI for identifying system information, P-RNTI for identifying paging information, RA-RNTI indicating a resource block used by a user to transmit a random access preamble, C-RNTI for identifying a user service, TPC-PUCCH-RNTI for identifying PUCCH uplink power control information, and TPC-PUSCH-RNTI for identifying PUSCH uplink power control information.

[0049] In the prior art, multiple transmission signals may be from multiple communication nodes (e.g., transmission nodes, base stations, etc.), and M transmission signals may be from M different TRPs, or from M different antenna panels, or from M different bandwidth parts (BWPs), or from M different carrier components (CCs), among which the M panels, M BWPs, or M CCs may belong to the same TRP or may belong to multiple TRPs.

[0050] In order to distinguish control channels from different TRPs, candidate CORESETs are grouped, each group includes at least one CORESET, and each CORESET has one upper layer parameter index, for example, CORESET group index coresetPoolIndex-r16. When multiple transmission signals are from different transmission nodes, physical downlink control information can be signaled by one DCI, and such a scheme is called cooperative transmission based on single physical downlink control information (Single DCI), and when physical downlink control channels are signaled by two or more DCIs, such a scheme is called cooperative transmission based on multi-physical downlink control information (Multi DCI).

[0051] A technique for improving reliability is to use hybrid automatic repeat request (HARQ), that is, after a terminal or a base station receives a transmission block, if it finds through detection that the reception is correct, it feeds back an acknowledgement (ACK), otherwise it feeds back a negative acknowledgement (NACK). ACK and NACK information can be collectively referred to as a HARQ response, and naturally, they can also be referred to as HARQ response information, HARQ-ACK information, HARQ-ACK, HARQ-ACK response, ACK / NACK information, and ACK / NACK codebook. Unless otherwise specified, the ACK / NACK in the embodiments of the present invention can also be referred to as a HARQ-ACK.

[0052] In the prior art, for all serving cells (or carrier components, CCs) corresponding to at least one TRP and PUCCH detection occasions that meet the requirements set by higher layers, a HARQ-ACK bit set of one HARQ, such as a HARQ-ACK codebook and a HARQ-ACK sub-codebook, is generated, and the HARQ-ACK codebook is fed back in a PUCCH resource or a PUSCH resource.

[0053] The priorities of different ACK information can be determined by at least one of higher layer signaling, physical layer signaling, or an agreed manner, and the priorities of ACK information corresponding to a transmission signal satisfy at least one of the following features: ACKs of the same priority can be aggregated into a same HARQ-ACK codebook, or ACKs of different priorities cannot be aggregated into a same HARQ-ACK codebook, or ACKs of the same priority can be aggregated for transmission in a physical uplink channel, or ACKs of different priorities cannot be aggregated for transmission in a physical uplink channel.

[0054] If the number N0 of TCI states configured in the RRC is greater than the number N1 of thresholds configured, it is necessary to select N1 TCI states or TCI state groups from the N0 TCI states based on the MAC CE to form a set, and then select one TCI state or TCI state group from the TCI state set using the TCI domain of the DCI to indicate the QCL value that the UE needs to use. Here, the value of one TCI state or TCI state group for indicating the TCI domain in the DCI is one code point (or called TCI code point), and each code point is associated with one TCI state or TCI state group, where the TCI state group includes at least two TCI states. Table 1 is a TCI state mapping table in the prior art, and the prior art is as shown in Table 1.

[0055] [Table 1]

[0056] In an embodiment of the present invention, the preset transmission configuration indication code point (TCI code point) is the first TCI code point in a TCI state mapping table corresponding to a transmission signal, and the number of TCI states is two or more. That is, the preset TCI code point is the first TCI code point in the TCI code point, and includes more than one TCI state. The TCI code point set is defined based on each BWP or CC. One TCI code point is one value of a TCI domain in a DCI, and this value is used to indicate one or one set of TCI states, and the one or one set of TCI states are from a TCI state set determined by an RRC or a MAC CE.

[0057] The spatial parameters related to a transmission signal refer to one of the spatial parameters corresponding to the transmission signal, the spatial parameters for transmitting the transmission signal, the spatial parameters for receiving the transmission signal, and a reference signal that is quasi-collocated with the transmission signal.

[0058] The operation of the method and apparatus for determining spatial parameters according to the embodiment of the present invention will now be described.

[0059] Example 1 This embodiment provides a method for determining spatial parameters, and FIG. 2 is a flowchart (1) of the method for determining spatial parameters provided by an embodiment of the present invention. As shown in FIG. 2, the method for determining spatial parameters in this embodiment includes the following steps:

[0060] In S102, determine priority information of N types of transmission signals based on the first configuration information, where N is an integer greater than one.

[0061] In S104, determine spatial parameter information corresponding to the same symbol based on the priority information, where the spatial parameter information is used for transmitting at least one type of transmission signal among the N types of transmission signals.

[0062] In addition, in the above embodiment, the transmission signal may be a reference signal, a physical control channel, a physical shared channel, etc., and the embodiment of the present invention is not limited thereto. The above symbol may generally be a time domain symbol, and the above priority information is used to indicate the priority of the transmission signal.

[0063] In addition, the above embodiment determines spatial parameter information corresponding to the same symbol based on the priority information of the transmission signal, and transmits the at least one transmission signal, for example, a receiving beam for receiving the at least one transmission signal, based on a beam corresponding to the determined spatial parameter of the transmission signal. Here, only at least one transmission signal is used, which may be all transmission signals of the N types of transmission signals, or may be K transmission signals with high priority among the transmission signals.

[0064] The spatial parameter determination method in this embodiment can determine priority information of N types of transmission signals based on the first configuration information, where N is an integer greater than 1, and determine spatial parameter information corresponding to the same symbol based on the priority information, where the spatial parameter information is used to transmit at least one type of transmission signal among the N types of transmission signals.

[0065] Thus, through the embodiment of the present invention, the problem of how to effectively determine spatial parameters corresponding to the same symbol in the prior art can be solved, and the effect of effectively transmitting at least one type of transmission signal on the same symbol using the spatial parameters can be achieved.

[0066] Preferably, the spatial parameter determination method in this embodiment can effectively determine corresponding spatial parameters when N transmission signals are involved in the same symbol in the scene of Multi-TRP transmission or Multi-Panel or high frequency transmission. For example, in the process of UE receiving multiple PDSCHs, such as PDSCH1 and PDSCH2, through the spatial parameter determination method in this embodiment, UE determines that the receiving beam corresponding to the high priority transmission signal is the receiving beam of PDSCH1 and PDSCH2.

[0067] In one embodiment, in said N types of transmission signals, the same type of transmission signals are associated with the same spatial parameter information, and different types of transmission signals are associated with different spatial parameter information.

[0068] In one embodiment, in the step S104, the step of determining spatial parameter information corresponding to the same symbol based on the priority information includes: The spatial parameters associated with K types of transmission signals having higher priorities among the N types of transmission signals are determined as spatial parameter information corresponding to the same symbol, where K is a positive integer and is less than or equal to T, T is the maximum number of spatial parameters corresponding to the same symbol, and T is set by a higher layer or determined based on the capability of the user equipment UE.

[0069] In the above embodiment, the K type transmission signals are multiple types of transmission signals with high priority among the N type transmission signals, and there may be multiple methods for determining the K type transmission signals. For example, multiple types of transmission signals with high priority are selected from the N type transmission signals as the K type transmission signals. For example, in this embodiment, when there are N type transmission signals (for example, N is 5), the N type transmission signals are sorted in order of priority, and the K type transmission signals with the highest priority among them can be selected as the K type transmission signals in the above embodiment (for example, K is 3). Alternatively, multiple types of transmission signals with the highest priority can be directly selected as the K type transmission signals from the N type transmission signals. For example, in this embodiment, when there are N type transmission signals (for example, N is 5), the N type transmission signals have two different priority levels (high priority and low priority), and the multiple types of transmission signals with the highest priority can be selected as the K type transmission signals.

[0070] On the other hand, for the same symbol, the maximum number of spatial parameters can be determined, which is the maximum value T of the number of spatial parameters corresponding to the same symbol, set by higher layers or based on UE capabilities, and the number of K needs to satisfy the restriction of T.

[0071] It should be noted that in the above embodiment, the number of spatial parameters of the same symbol is the maximum number of spatial parameters that the same time domain symbol of the communication node can transmit, so that the determined spatial parameters according to the technical solution in the above embodiment can correspond to the number of spatial parameters that the communication node can use in the same time domain symbol.The technical solution described in the above embodiment can realize that the UE determines spatial parameters for multiple transmission signals transmitted by one TRP (for example, transmission signals transmitted by different CCs or BWPs), or determines spatial parameters for transmission signals transmitted by different TRPs.

[0072] In one embodiment, in the step S104, the step of determining spatial parameter information corresponding to the same symbol based on the priority information includes: The method includes the step of dividing the N types of transmission signals into C transmission signal groups based on the second configuration information, where one or more types of transmission signals in each transmission signal group are associated with the same second configuration information, C is a positive integer, and C is less than or equal to N.

[0073] In another embodiment, the second configuration information can be divided into C groups based on higher layer signaling or a preset scheme, and each second configuration information group includes at least one second configuration information, and one or more transmission signals related to the same second configuration information group are divided into one transmission signal group.

[0074] For example, when the second configuration information is a CORESET group, transmission signals having the same COSRESET group index corresponding to the transmission signal are grouped together. For example, when the second configuration information X is divided into C groups, transmission signals having the same second configuration information X group index corresponding to the transmission signal are grouped together, where X can be replaced with one of CORESET index information, priority information for checking ACK information corresponding to the transmission signal, priority indicator PI (Priority indicator) information in physical downlink control information, virtual cell number information, physical cell identifier PCI information, type information of radio network temporary identifier RNTI, parameter information of downlink control information DCI, scheduling time interval information, channel type information, and carrier component CC index information.

[0075] In addition, in the above embodiment, the N types of transmission signals are grouped into C transmission signal groups based on the second configuration information, that is, the N types of transmission signals are grouped based on the second configuration information to obtain C transmission signal groups.

[0076] It should be further noted that for multiple types of transmission signals located in the same group, the priority of multiple types of transmission signals in the transmission signal group and their spatial parameters are determined according to the method for determining the priority of transmission signals in this embodiment. For transmission signals located in different groups, since they can be received simultaneously, there is no need to further determine the priority between them, and it is only necessary to use the spatial parameters of the corresponding transmission signal groups, or other preset methods can be adopted, and the embodiment of the present invention is not limited thereto.

[0077] In one embodiment, the second configuration information is: The information includes at least one of control resource set CORESET group information, CORESET index information, priority information for checking ACK information corresponding to a transmission signal, priority indication PI (Priority indicator) information in physical downlink control information, virtual cell number information, physical cell identifier PCI information, type information of radio network temporary identifier RNTI, parameter information of downlink control information DCI, scheduling time interval information, channel type information, and carrier component CC index information.

[0078] In one embodiment, in the step S104, the step of determining spatial parameter information corresponding to the same symbol based on the priority information includes: For the i-th transmission signal group among the C transmission signal groups, K i Determine the spatial parameter information related to the type of transmission signal as the spatial parameter information corresponding to the same symbol of one or more types of transmission signals in the i-th transmission signal group, where i is a positive integer and i is less than or equal to C; Here, K i is a positive integer and K i is T i is less than or equal to T i is the maximum value of the number of spatial parameters corresponding to the i-th transmission signal group in the same symbol, and T i is set by a higher layer or determined based on UE capabilities.

[0079] The i-th transmission signal group is any one of the C transmission signal groups, that is, i=1, 2, 3....C-1, C. i The transmission signal of the type is a high-priority transmission signal in the i-th transmission signal group, and for the i-th transmission signal group, iThere are multiple methods for determining the type of transmission signal. For example, among the multiple types of transmission signals in the i-th transmission signal group, the multiple types of transmission signals with high priority are determined as K i Select the type of transmission signal (for example, the top K signals with the highest priority) i Alternatively, the N-type transmission signals may be directly selected as K-type transmission signals from the N-type transmission signals, and the specific method may refer to the selection of the K-type transmission signals described above, and the description thereof will be omitted here.

[0080] On the other hand, for each i-th transmission signal group, a maximum number of spatial parameters may be determined, which is a maximum value of the number of spatial parameters corresponding to the i-th transmission signal group in the same symbol, based on the upper layer or UE capability; K i The number of i restrictions must be met.

[0081] In one embodiment, in the C transmission signal groups, K i A set of transmission signals of type K is a transmission signal of type K, i The sum of is K, Here, K is a positive integer and is less than or equal to T, the K type transmission signals are one or more types of transmission signals with high priorities determined by a preset scheme among the N type transmission signals, T is the maximum value of the number of spatial parameters corresponding to the same symbol, and T is set by a higher layer or determined based on the capability of a user equipment UE.

[0082] In addition, in the C transmission signal groups, K i Quantity K corresponding to the type of transmission signal i The superposition of K results in a quantity K corresponding to K types of transmission signals, i.e., a number of K i The sum of these is K.

[0083] In one embodiment, the method for determining the spatial parameters in this embodiment includes: determining M types of transmission signals with high priority in the C transmission signal groups, where M is a positive integer and is greater than T; The method further includes a step of determining, based on the priority of the transmission signals, spatial parameters associated with a T type transmission signal having a high priority among the M type transmission signals as spatial parameter information corresponding to the same symbol.

[0084] In one embodiment, the first configuration information is: It includes at least one of CORESET group information, CORESET index information, priority information of ACK information corresponding to a transmission signal, priority indication PI information in physical downlink control information, virtual cell number information, PCI information, RNTI type information, DCI parameter information, scheduling time interval information, channel type information, and CC index information.

[0085] In one embodiment, in the above step S102, the step of determining priority information of the N types of transmission signals based on the first configuration information includes: If the first configuration information is CORESET group information, determining that the smaller the CORESET group index of the CORESET group information corresponding to the transmission signal, the higher the priority indicated by the priority information of the transmission signal; or determining, when the first configuration information is CORESET index information, that the smaller the CORESET index corresponding to the transmission signal, the higher the priority indicated by the priority information of the transmission signal; or If the first configuration information is priority information of ACK information corresponding to a transmission signal, determining that the higher the priority information of the ACK information corresponding to the transmission signal, the higher the priority indicated by the priority information of the transmission signal, where the priority information of the ACK information corresponding to the transmission signal is determined by upper layer signaling or by a preset manner; or When the first configuration information is priority indication PI information in physical downlink control information, determining that the higher the priority information of the priority indication PI information in the physical downlink control information corresponding to the transmission signal, the higher the priority indicated by the priority information of the transmission signal, where the priority indication PI information in the physical downlink control information is determined by upper layer signaling or by a preset manner; or When the first configuration information is a virtual cell number, determining that the smaller the virtual cell number corresponding to the transmission signal, the higher the priority indicated by the priority information of the transmission signal; or If the first configuration information is a physical cell identifier, determining that the smaller the physical cell identifier corresponding to the transmission signal, the higher the priority indicated by the priority information of the transmission signal; or If the first configuration information is RNTI type information, determining that the higher the priority information of the RNTI type corresponding to the transmission signal, the higher the priority indicated by the priority information of the transmission signal, where the priority information of the RNTI type is determined by upper layer signaling or by a preset manner; or If the first configuration information is DCI parameter information, determining that the higher the priority information of the DCI parameter information corresponding to the transmission signal, the higher the priority indicated by the priority information of the transmission signal, where the priority information of the DCI parameter information is determined by higher layer signaling or by a preset manner; or If the first configuration information is channel type information, determining that the higher the priority information of the channel type information corresponding to the transmission signal, the higher the priority indicated by the priority information of the transmission signal, where the priority information of the channel type information is determined by higher layer signaling or by a preset manner; or If the first configuration information is scheduling time interval information, determining that the larger the scheduling time interval corresponding to the transmission signal, the higher the priority indicated by the priority information of the transmission signal; or When the first configuration information is CC index information, the method includes the step of determining that the smaller the CC index corresponding to the transmission signal, the higher the priority indicated by the priority information of the transmission signal.

[0086] In one embodiment, the method for determining the spatial parameters in this embodiment includes: The method further includes determining an associated CORESET group or CORESET for a transmission signal if the transmission signal does not have an associated CORESET group or CORESET. If there is no CORESET group corresponding to the transmission signal, an index of the CORESET group corresponding to the transmission signal is 0 by default, and if there is no CORESET corresponding to the transmission signal, an index of the CORESET corresponding to the transmission signal is 0 by default.

[0087] In one embodiment, the spatial parameter information comprises: The at least one of the following may be included: a quasi-collocation parameter, a quasi-collocation reference signal, a quasi-collocation reference signal of related spatial receive parameters, a spatial transmit filter, and a spatial relation reference signal.

[0088] The method for determining spatial parameters according to the embodiment of the present invention is applied to the first communication node and the second communication node, and the first communication node transmits the transmission signal according to the spatial parameters determined by the method according to the embodiment of the present invention, for example, determining a transmission beam used for transmitting the transmission signal. The second communication node can receive the transmission signal using the spatial parameters determined by the method according to the embodiment of the present invention, for example, determining a reception beam used for receiving the transmission signal.

[0089] The method for determining the spatial parameters in this embodiment is further described below by way of several exemplary embodiments.

[0090] Illustrative Example 1 In an exemplary embodiment, a scheduling node includes at least one first communication node, and N CORESET groups are set, each CORESET group includes at least one CORESET, the values ​​of the CORESET upper layer parameter index coresetPoolIndex-r16 in the same CORESET group are the same, and the priority of a transmission signal can be determined based on the value of coresetPoolIndex-r16 in the CORESET group, for example, the smaller the value of coresetPoolIndex-r16 of a CORESET corresponding to a scheduling transmission signal, the higher the priority of the corresponding transmission signal.

[0091] In another aspect, CORESET groups can be used to group transmission signals, for example, if CORESETs corresponding to scheduled transmission signals have the same coresetPoolIndex-r16 value, they can be grouped into the same transmission signal group.

[0092] N is an integer greater than 1, and without loss of generality, assume N=2, where CORESET group 1 includes CORESET1 and CORESET2, and the value of coresetPoolIndex-r16 corresponding to each CORESET is 0, and CORESET group 2 includes CORESET3 and CORESET4, and the value of coresetPoolIndex-r16 corresponding to each CORESET is 1, and transmission signal 1 and transmission signal 2 are scheduled using DCI1 in CORESET1 in CORESET group 1 and DCI3 in CORESET3 in CORESET group 2, respectively, and the value of the COREST group index coresetPoolIndex-r16 of the CORESET corresponding to DCI1 is 0 and the value of the COREST group index coresetPoolIndex-r16 of the CORESET corresponding to DCI3 is 1, then the priority of transmission signal 1 is higher than the priority of transmission signal 2.

[0093] When transmission signal 1 and transmission signal 2 are scheduled using DCI1 in CORESET1 in CORESET group 1 and DCI2 in CORESET2 in CORESET group 1, respectively, DCI1 and DCI2 have the same CORESET group index value, so transmission signal 1 and transmission signal 2 can be divided into the same transmission signal group. And it is necessary to determine the priority of the spatial parameter based on at least one of the CORESET index, virtual cell number information, physical cell identifier PCI information, type information of radio network temporary identifier RNTI, parameter information of downlink control information DCI, scheduling time interval information, channel type information, CC index information, etc., and to determine the spatial parameters used to transmit the transmission signals in the transmission signal group based on the priority.

[0094] Based on the above description, since the priority of transmission signal 1 is higher than the priority of transmission signal 2, the spatial parameters corresponding to transmission signal 1 are determined as preferred spatial parameters, i.e., when transmission signal 1 and transmission signal 2 are transmitted in the same symbol, the spatial parameters related to transmission signal 1 are preferentially used as the spatial parameters corresponding to this symbol, and transmission signal 1 and transmission signal 2 are received by the beam determined by this spatial parameter. Note that, finally, the spatial parameters for receiving the transmission signals may be more than one, i.e., the final spatial parameters are spatial parameters corresponding to K transmission signals with higher priorities of the transmission signals, or K transmission signals with higher priorities in each transmission signal group. i are spatial parameters corresponding to the K transmitted signals, i is a positive integer, the maximum number of spatial parameters of the i-th transmission signal group, and K i The sum of K and K is smaller than K, i=1,...,C, where C is the number of transmission signal groups, and K is an integer greater than or equal to 1 and smaller than N. i is determined by higher layer signaling configuration or UE capabilities.

[0095] Illustrative Example 2 In an exemplary embodiment, the network includes at least one first communication node, and N CORESETs are set, each of which has a CORESET-related index controlResourceSetId for identifying the CORESET.

[0096] The priority of a transmission signal can be determined based on the value of the CORESET index controlResourceSetId. For example, the smaller the value of the controlResourceSetId of the CORESET corresponding to the DCI of a scheduled transmission signal, the higher the priority of the corresponding transmission signal.

[0097] In addition, the controlResourceSetId index can be divided into multiple controlResourceSetId sets, which can be set by higher layer signaling or formed in an agreed manner, for example, a controlResourceSetId smaller than A1 is one controlResourceSetId set, and a controlResourceSetId larger than A1 is one controlResourceSetId set.

[0098] If the CORESET indexes corresponding to the DCIs of multiple scheduled transmission signals are in the same controlResourceSetId set, they can be considered as the same transmission signal group. N is an integer greater than 1, and without loss of generality, assume that N=4, where CORESET1, CORESET2, CORESET3 and CORESET4 are set, and the values ​​of their corresponding CORESET indexes are 0-3, respectively.

[0099] In addition, when A1=2 is set, the transmission signals scheduled using DCIs corresponding to CORESET1 and CORESET2 constitute one transmission signal group, and the transmission signals scheduled using DCIs corresponding to CORESET3 and CORESET4 constitute one transmission signal group. In a specific transmission process, transmission signal 1 and transmission signal 2 are scheduled using DCI1 in CORESET1 and DCI3 in CORESET3, respectively, and the value of the COREST index of CORESET corresponding to DCI1 is 0, and the value of the COREST index of CORESET corresponding to DCI3 is 2, so that the priority of transmission signal 1 is higher than the priority of transmission signal 2.

[0100] When transmission signal 1 and transmission signal 2 are scheduled using DCI1 in CORESET1 and DCI2 in CORESET2, respectively, transmission signal 1 and transmission signal 2 can be divided into the same transmission signal group because DCI1 and DCI2 are in the same CORESET index set, and the CORESET index corresponding to DCI1 is smaller than the CORESET index corresponding to DCI2. Therefore, the priority of the spatial parameters of transmission signal 1 is higher than the priority of the spatial parameters of transmission signal 2. Naturally, even for transmission signals in the same group, the priority of the transmission signals can be determined using information other than the CORESET index in the second configuration information.

[0101] Based on the above description, since the priority of transmission signal 1 is higher than the priority of transmission signal 2, the spatial parameters corresponding to transmission signal 1 are determined as preferred spatial parameters, i.e., when transmission signal 1 and transmission signal 2 are transmitted in the same symbol, the spatial parameters related to transmission signal 1 are preferentially used as the spatial parameters corresponding to this symbol, and transmission signal 1 and transmission signal 2 are received by the beam determined by this spatial parameter. Note that, finally, the spatial parameters for receiving the transmission signals may be more than one, i.e., the final spatial parameters are spatial parameters corresponding to K transmission signals with higher priorities of the transmission signals, or K transmission signals with higher priorities in each transmission signal group.i are spatial parameters corresponding to the K transmitted signals, i is a positive integer, the maximum number of spatial parameters of the i-th transmission signal group, and K i The sum of K and K is smaller than K, i=1,...,C, where C is the number of transmission signal groups, and K is an integer greater than or equal to 1 and smaller than N. i is determined by higher layer signaling configuration or UE capabilities.

[0102] Illustrative Example 3 In an example embodiment, the system includes at least one first communication node, the first communication node being capable of simultaneously transmitting multiple service types, including Ultra-reliable and Low Latency Communications (URLLC) services and Enhanced Mobile Broadband (eMBB) services.

[0103] Here, the priority of URLLC and eMBB is mainly indicated based on priority indicator (PI) information in the physical downlink control information, i.e., the value in the Priority indicator field in downlink control format 0-1, 0-2, 1-1 or 1-2 (DCI0_1 or DCI0_2, DCI1_1 or DCI1_2). The larger the PI value in a DCI, the higher the priority of the transmission signal corresponding to the DCI, and the higher the priority of the transmission signal can be transmitted.

[0104] For example, if the PI value of the DCI corresponding to the first transmission signal is 1 and the PI value of the DCI corresponding to the second transmission signal is 0, the priority of the second transmission signal is lower than the priority of the first transmission signal. Thus, the terminal can determine the priorities of eMBB and URLLC based on the indication of the received PI, and determine spatial parameters of the transmission signals based on the priorities of eMBB and URLLC, for example, if the PI indicates that the priority of eMBB is high, the priority of the transmission signal related to eMBB is higher than the priority of the transmission signal related to URLLC, otherwise the priority of the transmission signal related to eMBB is lower than the priority of the transmission signal related to URLLC.

[0105] In addition, transmission signals can be grouped based on the PI instruction; for example, transmission signals corresponding to a PI value of 1 are grouped into one group, and transmission signals corresponding to a PI value of 0 are grouped into another group.

[0106] For transmission signals in the same group, a priority of the transmission signal in the transmission signal group is determined according to at least one of a CORESET group index, a CORESET index, virtual cell number information, physical cell identifier PCI information, type information of the radio network temporary identifier RNTI, parameter information of downlink control information DCI, scheduling time interval information, channel type information, CC index information, etc., and a spatial parameter used for transmitting the transmission signal is determined based on the priority of the transmission signal, and the spatial parameter is a spatial parameter corresponding to K transmission signals with high priority of the transmission signal, or a spatial parameter corresponding to K transmission signals with high priority in each transmission signal group. i are spatial parameters corresponding to the K transmitted signals, i is a positive integer, the maximum number of spatial parameters of the i-th transmission signal group, and K i The sum of K and K is smaller than K, i=1,...,C, where C is the number of transmission signal groups, and K is an integer greater than or equal to 1 and smaller than N. i is determined by higher layer signaling configuration or UE capabilities.

[0107] Illustrative Example 4 In an exemplary embodiment, the system includes at least one first communication node, which can simultaneously transmit multiple transmission signals, such as transmission signal 1, transmission signal 2, transmission signal 3, and transmission signal 4. Higher layer or physical layer signaling sets virtual cell information vPCI in the transmission signals, and the virtual cell information is used to generate a sequence or a scrambling code, etc., of the transmission signals. Assume that the virtual cell vPCIs of transmission signals 1 to 4 are 1-4, respectively.

[0108] This allows the terminal to determine the priority of a transmission signal based on the magnitude of the received vPCI. For example, the smaller the virtual cell number corresponding to a transmission signal, the higher the priority of the transmission signal.

[0109] In another aspect, the transmission signals can be grouped based on the virtual cell number, for example, based on a set or agreed method, the virtual cell numbers are divided into a plurality of virtual cell number groups. The transmission signals in the same virtual cell number group of the virtual cell numbers corresponding to the transmission signals are grouped into one group. The priority of the transmission signals in the same transmission signal group can be determined based on the size of the virtual cell number corresponding to the transmission signal, for example, the priority of the transmission signal corresponding to the transmission signal with a small virtual cell number is high, and the priority of the transmission signals in the same group can be determined based on information other than the virtual cell number in the second configuration information.

[0110] and determining spatial parameters to be used for transmitting the transmission signals based on the priority of the transmission signals, the spatial parameters being spatial parameters corresponding to K transmission signals with high priority of the transmission signals, or K transmission signals with high priority in each transmission signal group. i are spatial parameters corresponding to the K transmitted signals, i is a positive integer, the maximum number of spatial parameters of the i-th transmission signal group, and K iThe sum of K and K is smaller than K, i=1,...,C, where C is the number of transmission signal groups, and K is an integer greater than or equal to 1 and smaller than N. i is determined by higher layer signaling configuration or UE capabilities.

[0111] Illustrative Example 5 In an exemplary embodiment, the system includes at least one first communication node, which can simultaneously transmit multiple transmission signals, such as transmission signal 1, transmission signal 2, transmission signal 3, and transmission signal 4. Higher layer or physical layer signaling sets physical cell identification PCI information PCI in the transmission signals, and the PCI is used to generate a sequence or scrambling code of the transmission signals, or to identify a physical cell corresponding to the transmission signals.

[0112] Assume that the PCIs of transmission signals 1 to 4 are 1 to 4, respectively. This allows the terminal to determine the priority of a transmission signal based on the size of the received PCI. For example, the smaller the PCI corresponding to a transmission signal, the higher the priority of the transmission signal.

[0113] In another aspect, transmission signals can be grouped based on PCI, for example, by dividing the PCI into a plurality of PCI groups based on a set or agreed upon method. Transmission signals in the same PCI group of the PCI corresponding to the transmission signals are grouped into one group. The priority of the transmission signals in the same transmission signal group can be determined based on the size of the PCI corresponding to the transmission signal, for example, the priority of the transmission signal corresponding to the transmission signal with a small PCI is high, and naturally, the priority of the transmission signal can be determined based on information other than the physical cell number in the second configuration information even for the transmission signals in the same group.

[0114] and determining spatial parameters to be used for transmitting the transmission signals based on the priority of the transmission signals, the spatial parameters being spatial parameters corresponding to K transmission signals with high priority of the transmission signals, or K transmission signals with high priority in each transmission signal group. iare spatial parameters corresponding to the K transmitted signals, i is a positive integer, the maximum number of spatial parameters of the i-th transmission signal group, and K i The sum of K and K is smaller than K, i=1,...,C, where C is the number of transmission signal groups, and K is an integer greater than or equal to 1 and smaller than N. i is determined by higher layer signaling configuration or UE capabilities.

[0115] Illustrative Example 6 In an exemplary embodiment, the system includes at least one first communication node, which is capable of simultaneously transmitting multiple transmission signals, such as transmission signal 1, transmission signal 2, transmission signal 3, and transmission signal 4. Higher layer or physical layer signaling configures multiple carrier components CC in the transmission signals, and the CC is used to transmit at least one of the transmission signals 1 to 4.

[0116] Assume that the CC indexes corresponding to transmission signals 1 to 4 are 0 to 3, respectively. Thus, the terminal can determine the priority of the transmission signal based on the magnitude of the received CC index. For example, the smaller the CC index corresponding to a transmission signal, the higher the priority of the transmission signal.

[0117] In another aspect, the transmission signals can be grouped based on the CC index, for example, based on a set or agreed method, the CC index is divided into a plurality of CC index groups. The transmission signals in the same CC index group of the CC index corresponding to the transmission signals are grouped into one group. The priority of the transmission signals in the same group can be determined based on the magnitude of the CC index corresponding to the transmission signals, for example, the priority of the transmission signal corresponding to the transmission signal with a small CC index is high, and the priority of the transmission signal can be determined based on information other than the CC index in the second configuration information for the transmission signals in the same group.

[0118] and determining spatial parameters to be used for transmitting the transmission signals based on the priority of the transmission signals, the spatial parameters being spatial parameters corresponding to the K transmission signals with high priority of the transmission signals, or the K transmission signals with high priority in each transmission signal group. i are spatial parameters corresponding to the K transmitted signals, i is a positive integer, the maximum number of spatial parameters of the i-th transmission signal group, and K i The sum of K and K is smaller than K, i=1,...,C, where C is the number of transmission signal groups, and K is an integer greater than or equal to 1 and smaller than N. i is determined by higher layer signaling configuration or UE capabilities.

[0119] Illustrative Example 7 In an exemplary embodiment, the system includes at least one first communication node, and the first communication node can simultaneously transmit a number of transmission signals, such as transmission signal 1, transmission signal 2, transmission signal 3, and transmission signal 4. The transmission signals include at least one of various reference pilots, PDSCH, and PUSCH, in which the scheduling time interval information corresponding to transmission signal 1 to transmission signal 4 is T1-T4. For the scheduling time interval information, the interval between the last symbol occupied by the RE resource corresponding to the DCI related to the transmission signal and the first symbol of the RE resource corresponding to the transmission of the transmission signal is the scheduling time interval information.

[0120] The DCI related to the transmission signal refers to a DCI for scheduling a PDSCH or a PUSCH, or a DCI for triggering an aperiodic reference signal, or a DCI for activating a semi-persistent reference signal, so that the terminal can determine the priority of the transmission signal based on the size of the scheduling time interval information, for example, the larger the scheduling time interval information corresponding to the transmission signal, the higher the priority of the transmission signal.

[0121] In another aspect, transmission signals can be grouped based on the scheduling time interval information, for example, the scheduling time interval information is divided into a plurality of scheduling time interval information groups based on a set or agreed upon method. Transmission signals in the same scheduling time interval information group of the scheduling time interval information corresponding to the transmission signals are grouped into one group. The priority of the transmission signals in the same transmission signal group can be further determined based on the size of the scheduling time interval information corresponding to the transmission signals, for example, the priority of the transmission signal corresponding to the transmission signal with the larger scheduling time interval information is higher, and naturally, the priority of the transmission signals in the same group can be determined based on information other than the scheduling time interval information in the second configuration information.

[0122] and determining spatial parameters to be used for transmitting the transmission signals based on the priority, the spatial parameters being spatial parameters corresponding to K transmission signals with high priority of the transmission signals, or K transmission signals with high priority in each transmission signal group. i are spatial parameters corresponding to the K transmitted signals, i N is a positive integer and is the maximum number of spatial parameters of the i-th transmission signal group, the sum of Ki of all transmission signal groups is less than K, i=1,...,C, C is the number of transmission signal groups, K is an integer greater than or equal to 1 and less than N, and K and Ki are determined by higher layer signaling configuration or UE capability.

[0123] Illustrative Example 8 In an exemplary embodiment, the system includes at least one first communication node, which can simultaneously transmit multiple transmission signals, such as transmission signal 1, transmission signal 2, transmission signal 3, and transmission signal 4. Each transmission signal can be scrambled with a different RNTI.

[0124] Assume that the RNTIs corresponding to transmission signals 1 to 4 are RNTI1 to RNTI4, respectively. Thus, the terminal can determine the priority of a transmission signal based on the received RNTI information, for example, a transmission signal scrambled with an S-RNTI of a system information type or a P-RNTI of a paging type has a high priority, a transmission signal scrambled with a control signaling type such as a TPC-PUCCH-RNTI or TPC-PUSCH-RNTI has a second high priority, and a transmission signal scrambled with an SPS C-RNTI or C-RNTI of a transmission data type has the lowest priority.

[0125] Of course, the priority of different RNTIs is not limited to this example, and the priority of the different RNTIs can be determined based on an agreed-upon method or a method set by higher layer signaling. The priority of a transmission signal is determined based on the priority of the RNTI associated with the transmission signal. The transmission signals can also be grouped based on the RNTI associated with the transmission signal, for example, the RNTIs are divided into a plurality of RNTI groups based on a set or agreed-upon method. Transmission signals in the same RNTI group of RNTIs corresponding to the transmission signals are grouped into one group.

[0126] For transmission signals within the same group, the priority of a transmission signal within a transmission signal group can be further determined based on the priority of the RNTI corresponding to the transmission signal; for example, a transmission signal corresponding to a transmission signal with a high priority of the RNTI associated with the transmission signal has a high priority, and naturally, the priority of a transmission signal can also be determined for transmission signals in the same group based on other information about the RNTI in the second configuration information.

[0127] and determining spatial parameters to be used for transmitting the transmission signals based on the priority of the transmission signals, the spatial parameters being spatial parameters corresponding to the K transmission signals with high priority of the transmission signals, or the K transmission signals with high priority in each transmission signal group. i are spatial parameters corresponding to the K transmitted signals, iis a positive integer, the maximum number of spatial parameters of the i-th transmission signal group, and K i The sum of K and K is smaller than K, i=1,...,C, where C is the number of transmission signal groups, and K is an integer greater than or equal to 1 and smaller than N. i is determined by higher layer signaling configuration or UE capabilities.

[0128] Illustrative Example 9 In an exemplary embodiment, the present invention includes at least one first communication node, and the first communication node can simultaneously transmit multiple transmission signals, such as transmission signal 1, transmission signal 2, transmission signal 3, and transmission signal 4. Each transmission signal corresponds to parameter information of different downlink control information (DCI). The parameter information of the downlink control information (DCI) includes at least one of a format of the DCI, a scrambling sequence of the DCI, a search space index in which the DCI is located, a CORESET index in which the DCI is located, and a CORESET group index in which the DCI is located.

[0129] Assume that DCI parameter information 1 to DCI parameter information 4 correspond to transmission signals 1 to 4. Thus, the terminal can determine the priority of the transmission signal based on the received DCI parameter information, and for example, the priority of a transmission signal having a smaller search space index in which the DCI is located is higher, such that the priority of the formats corresponding to the DCI corresponding to the transmission signal gradually decreases in the order of formt0-0, format1-0, format2-0, format0-1, format1-1, format2-1, format2-3, and format2-4, or the priority of a DCI format determined by another scheme determines the priority of the transmission signal.

[0130] and determining the priority of the transmission signal based on the DCI parameter information associated with the transmission signal.

[0131] In addition, the transmission signals can be grouped based on DCI parameter information related to the transmission signals, for example, based on a set or agreed upon method, the DCI parameters are divided into multiple groups, and transmission signals in the same DCI group for which the DCI parameters corresponding to the transmission signals are grouped together.

[0132] The transmission signals in the same group can further correspond to the transmission signals and determine the priority of the transmission signals in the transmission signal group according to at least one of CORESET index, virtual cell number information, physical cell identifier PCI information, radio network temporary identifier RNTI type information, scheduling time interval information, CC index information, etc. as necessary, and determine spatial parameters used to transmit the transmission signals and determine spatial parameters used to receive the transmission signals according to the priority, and the spatial parameters are spatial parameters corresponding to K transmission signals with high priority of the transmission signals, or K transmission signals with high priority in each transmission signal group. i are spatial parameters corresponding to the K transmitted signals, i is a positive integer, the number of maximum spatial parameters of the i-th transmission signal group, and K i The sum of K and K is smaller than K, i=1,...,C, where C is the number of transmission signal groups, and K is an integer greater than or equal to 1 and smaller than N. i is determined by higher layer signaling configuration or UE capabilities.

[0133] Illustrative Example 10 In an exemplary embodiment, the present invention includes at least one first communication node, and the first communication node can simultaneously transmit multiple transmission signals, such as transmission signal 1, transmission signal 2, transmission signal 3, and transmission signal 4, where the transmission signals mainly refer to various physical channels, and each transmission signal is transmitted through a different channel type, including but not limited to PDCCH, PDSCH, PUCCH, and PUSCH.

[0134] Assume that transmission signals 1 to 4 correspond to PDCCH1, PDCCH2, PDSCH1, and PDSCH2, so that the terminal can determine the priority of the transmission signal according to the received channel type, for example, the priority of the physical control channel is higher than the priority of a physical shared type channel, and the priority of the physical downlink channel is higher than the priority of a physical uplink channel.

[0135] and determining a priority for the transmission based on a channel type associated with the transmission.

[0136] The transmission signals may also be grouped based on the channel type associated with the transmission signals, e.g., based on a configured or agreed upon scheme, transmission signals whose channel type is a control channel may be grouped together, and transmission signals whose channel type is a physical shared channel may be grouped together.

[0137] The transmission signals in the same group can further determine the priority of the transmission signals based on at least one of CORESET index, virtual cell number information, physical cell identifier PCI information, type information of radio network temporary identifier RNTI, parameter information of downlink control information DCI, scheduling time interval information, CC index information, etc. corresponding to the transmission signals, and determine spatial parameters used to transmit the transmission signals and determine spatial parameters used to receive the transmission signals based on the priority, where the spatial parameters are spatial parameters corresponding to K transmission signals with high priority of the transmission signals, or K transmission signals with high priority in each transmission signal group. i are spatial parameters corresponding to the K transmitted signals, i is a positive integer, the maximum number of spatial parameters of the i-th transmission signal group, and K i The sum of K and K is smaller than K, i=1,...,C, where C is the number of transmission signal groups, and K is an integer greater than or equal to 1 and smaller than N. i is determined by higher layer signaling configuration or UE capabilities.

[0138] Illustrative Example 11 In an exemplary embodiment, the system includes at least one first communication node, and the first communication node can simultaneously transmit multiple service types including a first transmission signal 1 and a second transmission signal, of which the first transmission signal may be one of PUSCH1, PUCCH1, and PDSCH1, and the second transmission signal may be one of PUSCH2, PUCCH2, and PDSCH2.

[0139] Here, the priority is mainly indicated based on the priority indication PI (Priority indicator) information in the physical downlink control information, i.e., the value in the Priority indicator field in downlink control format 0-1, 0-2, 1-1 or 1-2 (DCI0_1 or DCI0_2, DCI1_1 or DCI1_2). The larger the PI value in a DCI, the higher the priority of the transmission signal corresponding to that DCI is, and the higher the priority it can be transmitted.

[0140] For example, if the PI value of the DCI corresponding to the first transmission signal is 1 and the PI value of the DCI corresponding to the second transmission signal is 0, the priority of the second transmission signal is lower than the priority of the first transmission signal, and conversely, the priority of the second transmission signal is higher, so that the terminal can determine the priorities of the first transmission signal and the second transmission signal according to the received PI indication, and determine the spatial parameters of the transmission signals according to the priorities.

[0141] Also, transmission signals can be grouped based on the indication of the PI, for example, transmission signals corresponding to a PI value of 1 are grouped into one group, and transmission signals corresponding to a PI value of 0 are grouped into another group. For transmission signals in the same group, the priority of spatial parameters in the transmission signal group is determined based on at least one of a CORESET group index, a CORESET index, virtual cell number information, physical cell identifier PCI information, type information of radio network temporary identifier RNTI, parameter information of downlink control information DCI, scheduling time interval information, channel type information, CC index information, etc., and spatial parameters used to transmit the transmission signals are determined based on the priority of the transmission signals.

[0142] In addition, the transmission signals may first be grouped based on the CORESET group, and a transmission signal whose corresponding CORESET group index is 0 may be compared with a transmission signal whose CORESET group index is 1.The priority of the transmission signal may be determined based on the magnitude of the PI value, such as a transmission signal with a larger PI value having a higher priority among transmission signals within the same CORESET group.

[0143] The spatial parameters correspond to K transmission signals with high priority, or K transmission signals with high priority in each transmission signal group. i are spatial parameters corresponding to the K transmitted signals, i is a positive integer, the number of maximum spatial parameters of the i-th transmission signal group, and K i The sum of K and K is smaller than K, i=1,...,C, where C is the number of transmission signal groups, and K is an integer greater than or equal to 1 and smaller than N. i is determined by higher layer signaling configuration or UE capabilities.

[0144] In exemplary embodiment 1 to exemplary embodiment 10, the base station transmits a transmission signal according to a spatial parameter corresponding to the transmission signal, or transmits the transmission signal based on the determined spatial parameter, and the terminal receives one of the transmission signals based on the determined spatial parameter, and the received transmission signal may be all transmission signals transmitted by the base station, or may be K transmission signals with high priority.
