The first antenna panel corresponding to the first frequency band and the second antenna panel corresponding to the second frequency band have a correlation, and the correlation is used for representing that the first antenna panel and the second antenna panel meet preset conditions.

Therefore, when the first antenna panel corresponding to the first frequency band and the second antenna panel corresponding to the second frequency band have a correlation, the terminal equipment can directly determine the transmission parameters of the second frequency band according to the transmission parameters of the first frequency band, and the transmission parameters of the second frequency band are not required to be obtained by scanning on the second frequency band, so that the communication cost is reduced, and the communication efficiency is improved.

In the case that the transmission parameters of the first frequency band include the transmission beam parameters of the first frequency band, the method for determining the transmission parameters of the second frequency band according to the configuration information and the indication information may include: the transmission parameter determining means determines that the transmission beam parameters of the second frequency band include transmission beam parameters of the first frequency band.

The first information is used for representing that a first antenna panel and a second antenna panel with a correlation exist in the terminal equipment, and the configuration information and the indication information are obtained based on the first information.

In this way, since the second antenna panel has a correlation with the first antenna panel, it is possible to switch directly from the third antenna panel to the second antenna panel.

Detailed Description

In embodiments of the application, words such as "exemplary" or "such as" are used to mean serving as an example, instance, or illustration. Any embodiment or design described herein as "exemplary" or "e.g." in an embodiment should not be taken as preferred or advantageous over other embodiments or designs. Rather, the use of words such as "exemplary" or "such as" is intended to present related concepts in a concrete fashion.

The terms "first" and "second" are used below for descriptive purposes only and are not to be construed as indicating or implying relative importance or implicitly indicating the number of technical features indicated. Thus, a feature defining "a first" or "a second" may explicitly or implicitly include one or more such feature. In the description of the embodiments of the present application, unless otherwise indicated, the meaning of "a plurality" is two or more.

For the convenience of understanding by those skilled in the art, the terms involved in the embodiments of the present application will be briefly described herein.

1. Beam (beam)

A beam is a communication resource. The beam may be a wide beam, or a narrow beam, or other type of beam. The technique of forming the beam may be a beam forming technique or other means of technique. The beamforming technique may specifically be a digital beamforming technique, an analog beamforming technique, a hybrid digital/analog beamforming technique. Different beams may be considered different resources. The same information or different information may be transmitted through different beams.

Multiple beams having the same or similar communication characteristics may be considered one beam. One or more antenna ports may be included in a beam for transmitting data channels, control channels, probe signals, etc. For example, a transmit beam refers to the signal strength distribution in spatially different directions of a wireless signal after being transmitted through an antenna, and a receive beam refers to the signal strength distribution in spatially different directions of a wireless signal received from the antenna. It is understood that one or more antenna ports comprised by a beam may be considered as a set of antenna ports.

When using low or medium frequency bands, the signal may be transmitted omnidirectionally or through a wider angle. When the high-frequency band is used, since the wavelength of the high-frequency band is short, the antenna size is small, and thus many antenna elements can be arranged at the transmitting end and the receiving end to constitute an antenna array. In this way, the transmitting end transmits the signal with a certain beam forming weight, so that the transmitted signal forms a beam with spatial directivity, and the receiving end receives the signal with the certain beam forming weight by using the antenna array, thereby improving the receiving power of the signal at the receiving end and resisting the path loss.

In the protocol of the new radio, NR, the beam may be embodied as spatial filter (spatial domain filter), spatial filter (spatial filter), spatial parameter (spatial domain parameter), spatial parameter (spatial parameter), spatial setting (spatial domain setting), spatial setting (spatial setting), QCL information, QCL hypothesis, QCL indication, etc. The beam may be indicated by a transmit configuration indication (transmission configuration indicator, TCI) state (state). Beams may also be indicated by spatial relationship (spatial relationship) parameters. Therefore, in the embodiment of the present application, the beam may be replaced by a spatial filter, a spatial parameter, a spatial setting, QCL information, a QCL hypothesis, a QCL indication, a TCI state (including a DL TCI state and/or a UL TCI state), a spatial relationship, and the like. The terms may be equivalent to each other. Of course, the beam may be replaced by other terms representing the beam, and embodiments of the present application are not limited.

2、QCL

QCL is used to denote that multiple resources have one or more identical or similar communication characteristics between them, and the same or similar communication configuration may be employed for multiple resources having QCL relationships. For example, if two antenna ports have a QCL relationship, the channel large scale characteristics of one port transmitting one symbol can be inferred from the channel large scale characteristics of the other port transmitting one symbol. The channel large scale characteristics may include: delay spread, average delay, doppler spread, doppler shift, average gain, reception parameters, terminal device reception beam number, transmit/receive channel correlation, reception angle of arrival, spatial correlation of receiver antennas, main angle of arrival (AoA), average angle of arrival, extension of AoA, etc.

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

3. Quasi co-position hypothesis (QCL assumption)

Quasi co-location assumption refers to assuming whether there is a QCL relationship between two antenna ports. The configuration and indication of quasi-parity hypotheses may be used to aid the receiving end in the reception and demodulation of signals. For example, if the receiving end confirms that the a-port and the B-port have QCL relationship, the receiving end may use the channel large-scale characteristic parameter measured on the a-port for measurement and demodulation of the signal on the B-port.

4. Airspace quasi-co-position (spatial QCL)

Spatial quasi-co-location is one type of QCL. The understanding of airspace may be from two angles: from the transmitting end or from the receiving end. From the transmitting end, if two antenna ports are spatially co-located, the corresponding beam directions of the two antenna ports are spatially coincident. From the receiving end, if two antenna ports are spatially co-located, the receiving end can receive signals transmitted by the two antenna ports in the same beam direction.

5. Reference Signal (RS)

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

The downlink communication includes transmission of downlink physical channels and downlink signals. Wherein, the downlink physical channel comprises: broadcast channel (physical broadcast channel, PBCH), downlink control channel (physical downlink control channel, PDCCH), downlink data channel (physical downlink shared channel, PDSCH), etc. The downlink signal includes: 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) (no such signal in NR), fine synchronization signal (time/frequency tracking referenee signal, TRS) (no such signal in LTE), LTE/NR positioning signal (positioning referenee signal), and the like.

6. Carrier aggregation (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 straightforward approaches is to increase the system transmission bandwidth. The CA technology may simultaneously configure a plurality of carriers, which may be continuous or discontinuous, in the frequency domain for use by one terminal device, so as to increase the total bandwidth of the terminal device, thereby achieving the effect of increasing the user capacity. CA technology is also used in NR.

7、TCI

TCI is a field in the downlink control information (downlink control information, DCI) for indicating PDSCH antenna port quasi co-location. The TCI is configured by radio resource control (radio resource control, RRC), referred to as a transport configuration indication state (TCI-state) in configuration signaling. The TCI-state comprises one or two QCL relations, which are used to indicate a certain consistency relation between the signal currently to be received and a certain reference signal known before. If a QCL relationship exists, the terminal device may receive the upcoming signal using the reception parameters when a certain reference signal was previously received.

The QCL type includes a type (type a), B type (type B), C type (type C), D type (type D). QCL types are different, and information acquired according to a reference signal is different. Common reference signals for QCL include: before RRC configuration, a synchronizing signal block (synchronization signal block, SSB) refers to the PDSCH and the DMRS in the PDCCH; after RRC configuration, SSB refers to TRS, TRS refers to DMRS, and CSI-RS refers to DMRS under sub 6G.

Above 6GHz, there is QCL type of type D. At this time, type a/B/c+type D (i.e., two types are configured, including D and another type, D is used to represent beam information), the current protocol specifies that three types of type a/B/C can only exist at the same time, wherein type a contains 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 type B and type C are arranged at the same time, type a may be arranged directly, which is equivalent to type a.

8. Antenna panel

The antenna panel may be comprised of one or more groups of antenna arrays, a group of antenna arrays comprising one or more antenna elements.

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

Currently, when a terminal device supports the capability of multiple frequency band communication, a beam sweep may be performed on each frequency band to determine the receive beam and the transmit beam used by the terminal device on each frequency band before the terminal device communicates with the network device. Without any a priori information (e.g. architectural assumptions of the terminal), the beam and transmission parameters determined by the terminal device on one frequency band indicated by the network device cannot be directly applied to communication transmissions of other frequency bands of the terminal device. Because the terminal device interacts with the network device multiple times in the process of beam scanning on a certain frequency band, the terminal performs beam scanning on each frequency band, which results in increased communication overhead and reduced communication efficiency.

In order to solve the above problems, an embodiment of the present application provides a method and an apparatus for determining a transmission parameter, where a terminal device obtains configuration information and indication information of a first frequency band, where the indication information of the first frequency band is used to indicate a transmission parameter of the first frequency band, and the configuration information is used to indicate the transmission parameter of the first frequency band to be used in the first frequency band and a second frequency band. And then, the terminal equipment determines the transmission parameters of the second frequency band according to the configuration information and the indication information. Therefore, when the first antenna panel corresponding to the first frequency band and the second antenna panel corresponding to the second frequency band have a correlation, the terminal equipment can directly determine the transmission parameters of the second frequency band according to the transmission parameters of the first frequency band, and the transmission parameters of the second frequency band are not required to be obtained by scanning on the second frequency band, so that the communication cost is reduced, and the communication efficiency is improved.

The transmission parameter determining method provided by the embodiment of the application is suitable for a communication system. Fig. 1 shows a structure of the communication system. As shown in fig. 1, the communication system may include: a network device 11 and a terminal device 12. The network device 11 and the terminal device 12 communicate using communication resources of a plurality of frequency bands, a first frequency band and a second frequency band being illustrated in fig. 1 as an example.

The network device 11 is configured to receive first information sent by the terminal device 12, where the first information is used to characterize that a first antenna panel corresponding to a first frequency band and a second antenna panel corresponding to a second frequency band with a correlation exist in the terminal device 12. The network device 11 is further configured to obtain the configuration information and the indication information of the first frequency band based on the first information, and send the configuration information and the indication information to the terminal device 12. The indication information is used for indicating the transmission parameters of the first frequency band, and the configuration information is used for indicating the transmission parameters of the first frequency band to be used for the first frequency band and the second frequency band.

In some embodiments, network device 11 is a device deployed in a radio access network to provide wireless communication functionality for terminal device 12. The network device 11 may include various forms of macro base stations, micro base stations (also referred to as small stations), relay stations, access points, and the like. The name of the network device 11 may vary in systems of different radio access technologies. For example, in a global system for mobile communications (global system for mobile communication, GSM) or code division multiple access (code division multiple access, CDMA) network, the network device 11 is referred to as a base transceiver station (base transceiver station, BTS); in wideband code division multiple access (wideband code division multiple access, WCDMA), the network device 11 is called a Node B (NB); in a long term evolution (long term evolution, LTE) system, the network device 11 is called an evolved node B (eNB). The network device 11 may also be a wireless controller in the context of a cloud wireless access network (cloud radio access network, CRAN). The network device 11 may also be a base station device in an NR network. The network device 11 may also be a wearable device or an in-vehicle device. The network device 11 may also be a transmission receiving node (transmission and reception point, TRP).

The terminal device 12 is configured to acquire the first information and send the first information to the network device 11. The terminal device 12 is further configured to receive configuration information and indication information of the first frequency band from the network device 11, and determine a transmission parameter of the second frequency band according to the configuration information and the indication information.

In some embodiments, the terminal device 12 may be a mobile terminal device, such as a mobile telephone (or "cellular" telephone) and a computer with a mobile terminal device, or may be a portable, pocket, hand-held, computer-built-in or vehicle-mounted mobile device that exchanges language and/or data with the RAN. For example, the terminal device 12 may be: a mobile phone, a tablet, a notebook, a palm, a mobile internet device (mobile internet device, MID), a wearable device, a Virtual Reality (VR) device, an augmented reality (augmented reality, AR) device, an industrial control (industrial control) wireless terminal device, an unmanned (self driving) wireless terminal device, a teleoperation (remote medical surgery) wireless terminal device, a smart grid (smart grid) wireless terminal device, a transportation security (transportation safety) wireless terminal device, a smart city (smart city) wireless terminal device, a smart home (smart home) wireless terminal device, etc. the terminal device 12 is shown in fig. 1 as an example of a mobile phone.

The basic hardware structure of the network device 11 and the terminal device 12 is similar, and includes elements included in the communication apparatus shown in fig. 2. The hardware configuration of the network device 11 and the terminal device 12 will be described below taking the communication apparatus shown in fig. 2 as an example.

As shown in fig. 2, the communication apparatus may include a processor 21 (or processing circuitry) and a communication interface 22 (or interface circuitry), the communication interface 22 being operable to communicate with other apparatuses or devices.

Optionally, the communication device may further comprise a memory 23 for storing computer instructions. The processor 21 and the memory 23 are coupled to each other for implementing a 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 for implementing a transmission parameter determining method 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 caused to execute a transmission parameter determination method provided in the following embodiments of the present application.

For example, the communication apparatus may be a communication device (terminal device or network device), or a chip or other component provided in the communication device. If the communication means is a communication device, the communication interface 22 may be implemented by a transceiver (or a transmitter and a receiver) in the communication device, which may be implemented by an antenna, a feeder, a codec, etc. in the communication device. If the communication device is a chip provided in the communication apparatus, the communication interface 22 is an input/output interface of the chip, such as an input/output pin, and the communication interface 22 is connected to a radio frequency transceiver in the communication apparatus to implement the transmission and reception of information through the radio frequency transceiver.

The processor 21 is a control center of the communication device, and may be one processor or a collective term of a plurality of processing elements. For example, the processor 21 may be a general-purpose central processing unit (central processing unit, CPU), or may be another general-purpose processor. The general-purpose processor may be a microprocessor or any conventional processor, etc., and may be, for example, a graphics processor (graphics processing unit, GPU), a digital signal processor (digital signal processing, DSP), etc.

The memory 23 may be, but is not limited to, a read-only memory (ROM) or other type of static storage device that can store static information and instructions, a random access memory (random access memory, RAM) or other type of dynamic storage device that can store information and instructions, or an electrically erasable programmable read-only memory (EEPROM), magnetic disk storage or other magnetic storage device, or any other medium that can be used to carry or store desired program code in the form of instructions or data structures and that can be accessed by a computer.

In the embodiment of the present application, the software programs stored in the memory 22 are different for the network device 11 and the terminal device 12, so that the functions realized by the network device 11 and the terminal device 12 are different. The functions performed with respect to the respective devices will be described in connection with the following flowcharts.

The communication interface 22 is used for connecting the communication device with other devices through a communication network, such as ethernet, RAN, wireless local area network (wireless local area networks, WLAN), etc. The communication interface 22 may include a receiving unit for receiving data and a transmitting unit for transmitting data.

The configuration shown in fig. 2 is not limiting of the communication device and the communication device may include more or less components than shown in fig. 2, or certain components may be combined, or a different arrangement of components may be provided.

It should be noted that, in the embodiment of the present application, the capability of the terminal device to support communications in multiple frequency bands is implemented by multiple antenna panels disposed in the terminal device, and typically, one frequency band corresponds to one or multiple antenna panels.

Fig. 2a is a schematic layout diagram of four antenna panels in a terminal device, by way of example. As shown in fig. 2a, the rectangular shapes of different fillers are used to represent the antenna panels corresponding to different frequency bands, and the water drop shapes of different fillers are used to represent the beams of different frequency bands. Assuming that the terminal device supports the capability of communication in a first frequency band corresponding to the antenna panels 1 and 2 and a second frequency band corresponding to the antenna panels 3 and 4.

As can be seen from fig. 2a, for the antenna panel 1 and the antenna panel 4, different antenna panels are used for the first frequency band and the second frequency band, so that there is no spatial correlation of the respective two beams. For the antenna panel 2 and the antenna panel 3, the first frequency band and the second frequency band use antenna panels integrated together, so the respective 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, as shown in fig. 2b, the antenna panel of the first frequency band and the antenna panel of the second frequency band may be coplanar or may be spliced up and down.

Based on the description of the hardware structures of the communication system and the communication device, the embodiment of the present application provides a transmission parameter determining method, and the transmission parameter determining method provided by the embodiment of the present application is described below with reference to the accompanying drawings.

As shown in fig. 3, the transmission parameter determination method may include the following steps 301 to 302.

301. The terminal equipment acquires configuration information and indication information of a first frequency band.

The indication information is used for indicating the transmission parameters of the first frequency band, and the configuration information is used for indicating the transmission parameters of the first frequency band to be used for 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, and the correlation is used for representing that the first antenna panel and the second antenna panel meet preset conditions. Specifically, the correlation is used for representing that the position of the first antenna panel and the position of the second antenna panel meet preset conditions. For example, the preset condition may be: the antenna panels of the multiple frequency bands are integrated together, or the distance between the antenna panels of the multiple frequency bands is smaller than a preset value, or the antenna panels of the multiple frequency bands are packaged in one chip, or the antenna panels of the multiple frequency bands are positioned on the same side/surface of the terminal, or the antenna panels of the multiple frequency bands are tightly spliced, and the like.

In a specific implementation, the configuration information is used to indicate that the transmission parameter of the first frequency band is used for a plurality of frequency bands including the first frequency band, each frequency band in the plurality of frequency bands corresponds to one antenna panel, and a correlation exists among the plurality of antenna panels corresponding to the plurality of frequency bands.

And assuming that the antenna panel 1 is identified as n78panel #1, the antenna panel 3 is identified as n78panel #3, and the antenna panel 6 is identified as n78panel #6. The antenna panel 2 is denoted by n257panel #2, the antenna panel 4 is denoted by n257panel #4, and the antenna panel 5 is denoted by n257panel #5.

For example, the partial parameters may include: the beam is received. Similarly, the determining, by the terminal device in step 302, that the transmission beam parameter of the second frequency band includes the transmission beam parameter of the first frequency band may specifically include: if the correlation degree is high, the terminal device may determine that all the transmission beam parameters of the first frequency band can be used for the second frequency band.

In a specific implementation, the first information may further include: and position information of the fourth antenna panel. Alternatively, the first information may further include identification of the fourth antenna panel and irrelevant information for indicating that the fourth antenna panel is irrelevant to other antenna panels. Alternatively, the first information may further include: the identification of the fourth antenna panel belongs to a set of antenna panels, and only one identification exists in the set.
