Hereinafter, the terms "first" and "second" are used for descriptive purposes only, and cannot be understood as indicating or implying relative importance or implicitly specifying the quantity of indicated technical features. Thus, a feature defined as "first" and "second" may explicitly or implicitly include one or more of these features. In the description of the embodiments of the present application, unless otherwise specified, "plurality" means two or more.

In order to facilitate the understanding of those skilled in the art, terms involved in the embodiments of the present application are briefly described here.

1. Beam

A beam is a communication resource. The beams can be wide beams, or narrow beams, or other types of beams. The beam forming technology may be a beam forming technology or other technical means. Specifically, the beamforming technology may be a digital beamforming technology, an analog beamforming technology, or a hybrid digital/analog beamforming technology. Different beams can be considered as different resources. The same information or different information can be transmitted through different beams.

Multiple beams with the same or similar communication characteristics may be considered as one beam. One or more antenna ports may be included in a beam for transmitting data channels, control channels, sounding signals, and the like. For example, the transmit beam refers to the signal strength distribution of the wireless signal in different directions in space after it is transmitted by the antenna, and the receive beam refers to the signal strength distribution of the wireless signal received from the antenna in different directions in space. It can be understood that one or more antenna ports included in a beam can be regarded as an antenna port set.

When using low or mid frequency bands, the signal can be sent omnidirectionally or through a wide angle. When using a high-frequency frequency band, since the wavelength of the high-frequency frequency band is relatively short, the size of the antenna is small, so many antenna elements can be arranged at the transmitting end and the receiving end to form an antenna array. In this way, the sending end sends signals with a certain beamforming weight, so that the sending signal forms a beam with spatial directivity, and the receiving end uses the antenna array to receive the signal with a certain beamforming weight, which can improve the receiving power of the signal at the receiving end. , against path loss.

In the new radio (NR) protocol, the embodiment of the beam can be a spatial domain filter (spatial domain filter), a spatial filter (spatial filter), a spatial domain parameter (spatial domain parameter), a spatial parameter (spatial parameter), Spatial domain setting, spatial setting, QCL information, QCL assumption, QCL indication, etc. The beam may be indicated by a transmission configuration indicator (TCI) state. Beams can also be indicated by a spatial relation parameter. Therefore, in this embodiment of the application, the beam can be replaced by a spatial filter, a spatial filter, a spatial parameter, a spatial parameter, a spatial setting, a spatial setting, QCL information, a QCL hypothesis, a QCL indication, TCI state (including DL TCI state and/or or UL TCI state), spatial relationship, etc. The above terms may also be equivalent to each other. Of course, the beam may also be replaced by other terms representing the beam, which is not limited in this embodiment of the present application.

2. QCL

QCL is used to indicate that multiple resources have one or more identical or similar communication features, and for multiple resources that have a QCL relationship, the same or similar communication configuration can be used. For example, if two antenna ports have a QCL relationship, then the large-scale properties of the channel transmitting a symbol on one port can be inferred from the large-scale properties of the channel transmitting a symbol on the other port. Channel large-scale characteristics can include: delay spread, average delay, Doppler spread, Doppler shift, average gain, receiving parameters, terminal equipment receiving beam number, transmitting/receiving channel correlation, receiving angle of arrival, receiver antenna The spatial correlation of , the main angle of arrival (angel-of-arrival, AoA), the average angle of arrival, the expansion of AoA, etc.

In a specific implementation, QCL is used to indicate whether at least two groups of antenna ports have a co-location relationship: QCL is used to indicate whether the channel state information reference signals sent by at least two groups of antenna ports come from the same transmission point, or QCL is used to indicate at least two groups Whether the channel state information reference signals sent by the antenna ports come from the same beam group.

3. Quasi-colocation assumption (QCL assumption)

The quasi-colocation assumption refers to assuming whether there is a QCL relationship between two antenna ports. The configuration and indication of the quasi-parity assumption can be used to help the receiving end to receive and demodulate the signal. For example, if the receiving end confirms that the A port and the B port have a QCL relationship, the receiving end may use the channel large-scale characteristic parameters measured on the A port for the measurement and demodulation of the signal on the B port.

4. Spatial QCL

Airspace quasi-colocation is a type of QCL. Airspace can be understood from two perspectives: from the sending end or from the receiving end. From the perspective of the transmitting end, if two antenna ports are quasi-colocated in space, then the corresponding beam directions of the two antenna ports are spatially consistent. From the perspective of the receiving end, if the two antenna ports are quasi-colocated in space, the receiving end can receive signals sent by the two antenna ports in the same beam direction.

5. Reference signal (reference signal, RS)

According to a long term evolution (long term evolution, LTE)/NR protocol, at the physical layer, uplink communication includes transmission of uplink physical channels and uplink signals. Wherein, the uplink physical channel includes: a random access channel (random access channel, PRACH), an uplink control channel (physical uplink control channel, PUCCH), an uplink data channel (physical uplink shared channel, PUSCH) and the like. Uplink signals include: channel sounding signal (sounding reference signal, SRS), uplink control channel demodulation reference signal (PUCCH de-modulation reference signal, PUCCH-DMRS), uplink data channel demodulation reference signal (PUSCH-DMRS), uplink phase Noise tracking signal (phase noise tracking reference signal, PTRS), uplink positioning signal (uplink positioning RS), etc.

Downlink communication includes the transmission of downlink physical channels and downlink signals. Wherein, the downlink physical channel includes: a broadcast channel (physical broadcast channel, PBCH), a downlink control channel (physical downlink control channel, PDCCH), a downlink data channel (physical downlink shared channel, PDSCH) and so on. Downlink signals include: primary synchronization signal (primary synchronization signal, PSS) / secondary synchronization signal (secondary synchronization signal, SSS), downlink control channel demodulation reference signal (PDCCH-DMRS), downlink data channel demodulation reference signal (PDSCH-DMRS ), phase noise tracking signal (PTRS), channel state information reference signal (channel status information reference signal, CSI-RS), cell signal (cell reference signal, CRS) (there is no such signal in NR), fine synchronization signal (time/ frequency tracking referenee signal (TRS) (there is no such signal in LTE), LTE/NR positioning signal (positioning referenee signal), etc.

6. Carrier aggregation (CA)

CA is a key technology in LTE-Advanced. In order to meet the requirements of single-user peak rate and system capacity improvement, one of the most direct ways is to increase the system transmission bandwidth. CA technology can configure multiple continuous or discontinuous frequency carriers to a terminal device at the same time, so as to increase the total bandwidth of the terminal device, thereby achieving the effect of increasing user capacity. CA technology is also used in NR.

7. TCI

The TCI is a field in downlink control information (downlink control information, DCI) used to indicate quasi-co-location of PDSCH antenna ports. The TCI is configured by a radio resource control (radio resource control, RRC), and is called a transmission configuration indication state (TCI-state) in configuration signaling. The TCI-state includes one or two QCL relationships, and the QCL is used to indicate a certain consistency relationship between a signal to be received currently and a previously known reference signal. If there is a QCL relationship, the terminal device can use the receiving parameters when receiving a certain reference signal before to receive the upcoming signal.

QCL types include type A (type A), type B (type B), type C (type C), and type D (type D). The QCL types are different, and the information obtained according to the reference signal is different. Common QCL reference signals include: before RRC configuration, the synchronization signal block (SSB) is used as a reference for DMRS in PDSCH and PDCCH; after RRC configuration, under sub6G, SSB is used as a reference for TRS, and TRS is used as a reference for DMRS , the CSI-RS is used as a reference for the DMRS.

For frequency bands above 6GHz, there will be a type D QCL type. At this time, type A/B/C+type D (that is, two configurations, including D and another type, D is used to represent beam information), the current agreement stipulates that only one of the three types of type A/B/C can exist at the same time , where type A contains the information of type B and type C, so it is meaningless to configure type A and type B/C at the same time. Similarly, if you configure type B and type C at the same time, it is equivalent to type A, and you can configure type A directly.

8. Antenna panel

The antenna panel may consist of one or more antenna arrays, and one antenna array includes one or more antenna elements.

It should be noted that the antenna panel involved in the embodiment of the present application may be replaced by an antenna array, antenna unit, antenna port, antenna group, antenna, etc., which is not limited in the embodiment of the present application.

At present, when the terminal device supports the communication capability of multiple frequency bands, before the terminal device communicates with the network device, beam scanning can be performed on each frequency band to determine the receiving beam and transmitting beam used by the terminal device on each frequency band . In the absence of any prior information (such as terminal architecture assumptions), the beam and transmission parameters determined by the terminal device in one frequency band indicated by the network device cannot be directly applied to the communication transmission of the terminal device in other frequency bands. Since the terminal device interacts with the network device multiple times during beam scanning on a certain frequency band, the terminal performs beam scanning on each frequency band, which will increase communication overhead and reduce communication efficiency.

In order to solve the above problems, the embodiment of the present application provides a transmission parameter determination method and device, the terminal equipment obtains the configuration information and the indication information of the first frequency band, the indication information of the first frequency band is used to indicate the transmission parameters of the first frequency band, the configuration information The transmission parameter indicating the first frequency band is for the first frequency band and the second frequency band. Afterwards, the terminal device determines the transmission parameters of the second frequency band according to the configuration information and the indication information. In this way, when the first antenna panel corresponding to the first frequency band has a correlation with the second antenna panel corresponding to the second frequency band, the terminal device can directly determine the transmission parameters of the second frequency band according to the transmission parameters of the first frequency band, without having to Scanning is performed on the second frequency band to obtain transmission parameters of the second frequency band, which reduces communication overhead and improves communication efficiency.

The hardware structure of the network device 11 and the terminal device 12 will be introduced below by taking the communication device shown in FIG. 2 as an example.

As shown in FIG. 2 , the communication device may include a processor 21 (or, a processing circuit) and a communication interface 22 (or, an interface circuit), and the communication interface 22 may be used to communicate with other devices or devices.

Optionally, the communication device may further include a memory 23 for storing computer instructions. The processor 21 and the memory 23 are coupled to each other, and are configured to implement the transmission parameter determination method provided in the following embodiments of the present application. Alternatively, the communication device may not include the memory 23, and the memory 23 may be located outside the communication device.

The processor 21, the memory 23, and the communication interface 22 are coupled to each other, and are used to implement the method for determining transmission parameters provided in the following embodiments of the present application. For example, when the processor 21 executes the computer instructions stored in the memory 23, the communication device is made to execute the transmission parameter determination method provided in the following embodiments of the present application.

For example, the communication device may be a communication device (terminal device or network device), or a chip or other components provided in the communication device. If the communication device is a communication device, the communication interface 22 may be realized by a transceiver (or a transmitter and a receiver) in the communication device, and the transceiver may be realized by an antenna, a feeder, a codec, etc. in the communication device. If the communication device is a chip installed in the communication device, the communication interface 22 is the input/output interface of the chip, such as input/output pins, etc. Components send and receive information.

The processor 21 is the control center of the communication device, and may be one processor, or a general term for multiple processing elements. For example, the processor 21 may be a general-purpose central processing unit (central processing unit, CPU), or other general-purpose processors.

In the embodiment of the present application, for the network device 11 and the terminal device 12, the software programs stored in the memory 22 are different, so the functions realized by the network device 11 and the terminal device 12 are different.

It should be noted that, in the embodiment of the present application, the ability of the terminal device to support communication in multiple frequency bands is realized through multiple antenna panels set in the terminal device, and generally one frequency band corresponds to one or more antenna panels.

Exemplarily, Fig. 2a is a schematic layout diagram of four antenna panels in a terminal device. As shown in Figure 2a, the antenna panels corresponding to different frequency bands are represented by rectangles with different fillings, and the beams of different frequency bands are represented by drop shapes of different fillings. It is assumed that the terminal device supports communication capabilities of the first frequency band and the second frequency band, the first frequency band corresponds to antenna panels 1 and 2 , and the second frequency band corresponds to antenna panels 3 and 4 .

It can be seen from FIG. 2a that, for the antenna panel 1 and the antenna panel 4, the first frequency band and the second frequency band use different antenna panels, so the corresponding two beams have no spatial correlation. For the antenna panel 2 and the antenna panel 3, the antenna panels integrated together are used for the first frequency band and the second frequency band, so the corresponding two beams have spatial correlation.

For another example, Fig. 2b is a schematic layout diagram of an antenna panel of a first frequency band and an antenna panel of a second frequency band in a network device. If the antenna panel of the first frequency band and the antenna panel of the second frequency band have a certain consistency assumption, then as shown in Figure 2b, the antenna panel of the first frequency band and the antenna panel of the second frequency band can be coplanar, or they can be spliced up and down.

Based on the introduction of the hardware structure of the above-mentioned communication system and communication device, the embodiment of the present application provides a method for determining a transmission parameter. The method for determining the transmission parameter provided by the embodiment of the present application will be described below with reference to the accompanying drawings.

As shown in FIG. 3 , the method for determining transmission parameters may include the following steps 301 - 302 .

301. A terminal device acquires configuration information and indication information of a first frequency band.

The indication information is used to indicate the transmission parameters of the first frequency band, and the configuration information is used to indicate that the transmission parameters of the first frequency band are used in the first frequency band and the second frequency band. The first antenna panel corresponding to the first frequency band and the second antenna panel corresponding to the second frequency band have a correlation relationship, and the correlation relationship is used to indicate that the first antenna panel and the second antenna panel meet a preset condition. Specifically, the correlation is used to characterize that the position of the first antenna panel and the position of the second antenna panel satisfy a preset condition. For example, the preset condition may be: the antenna panels of multiple frequency bands are integrated together, or the distance between the antenna panels of multiple frequency bands is less than a preset value, or the antenna panels of multiple frequency bands are packaged in one chip, or multiple The antenna panels of the frequency bands are located on the same side/face of the terminal, or the antenna panels of multiple frequency bands are closely spliced, etc.

The identifier of the antenna panel may be: FR1panel#1, where FR1 represents a frequency band range, and panel#1 represents No. 1 antenna panel among all antenna panels included in the terminal device.

In some embodiments, the correlation information is used to characterize the degree of correlation between the first antenna panel and the second antenna panel.

If the degree of correlation is low correlation, the terminal device may determine that part of the receiving beam parameters in the first frequency band can be used in the second frequency band. For example, the part of parameters may include: receiving beams. Similarly, the determination by the terminal device in step 302 above that the transmission beam parameters of the second frequency band include the transmission beam parameters of the first frequency band may specifically include: if the degree of correlation is high correlation, the terminal device may determine all transmission beam parameters of the first frequency band Can be used in the second frequency band. If the degree of correlation is low, the terminal device may determine that part of the transmit beam parameters in the first frequency band can be used in the second frequency band.

Antenna panels that do not have a correlation, such as the fourth antenna panel. In a specific implementation, the first information may further include: position information of the fourth antenna panel. Alternatively, the first information may further include an identifier of the fourth antenna panel and irrelevant information, where the irrelevant information is used to indicate that the fourth antenna panel is not related to other antenna panels. Alternatively, the first information may further include: an identifier of the fourth antenna panel, where the identifier of the fourth antenna panel belongs to an antenna panel set, and there is only one identifier in the set.

Reference signal resources may include: SRS, CSI-RS, SSB, etc. The types of reference signal resources are different, and the determined transmission parameters of the first frequency band may be different, that is, the transmission parameters of the first frequency band indicated by the configuration information may be different. For example, the SRS is used by the terminal equipment to determine at least one parameter: transmit spatial domain filter parameters, and transmit signal power control parameters. CSI-RS is used for terminal equipment to determine at least one parameter: receiving beam, receiving spatial filter parameters, QCL relationship of receiving signals, time offset compensation of receiving signals, time domain extension of receiving signals, frequency offset compensation of receiving signals, receiving Doppler shift of the signal.
