Description

Signal transmission method and communication device

Technical field

The present application relates to the field of wireless communications technologies, and in particular, to a signal transmission method and a communication device.

Background technique

In the New Radio system, User Equipment can transmit data on multiple carriers or multiple BWPs of one carrier. In the current standard, different signals on each carrier respectively correspond to respective Quasi Co-location (QCL) hypothesis information, and one QCL hypothesis information corresponds to a UE receiving beam.

At a certain transmission time i, there may be a case where the signal on the carrier 1 and the signal on the carrier 2 overlap in time. For example, as shown in FIG. 1A, the subcarrier Spacing (SCS) of the carrier 1 is 15 kHz, and the carrier 2 The subcarrier spacing is 15 kHz, and signal 1 on carrier 1 overlaps with signal 3 on carrier 2 in time. In this case, if the QCL hypothesis information of the signal on carrier 1 and the QCL hypothesis information of the signal on carrier 2 are not the same, the UE cannot simultaneously receive signals on the two carriers at the same time. When the numerology of carrier 1 and carrier 2 are different, that is, when the subcarrier Spacing (SCS) is different, there may even be a case where one signal on carrier 1 and multiple signals on carrier 2 overlap in time. For example, as shown in FIG. 1B, the subcarrier Spacing (SCS) of carrier 1 is 15 kHz, the subcarrier spacing of carrier 2 is 60 kHz, and one symbol of carrier 1 corresponds to four symbols of carrier 2. Signal 1 on carrier 1 and signal 3, signal 4, signal 5, and signal 6 on carrier 2 overlap in time, and signal 2 on carrier 1 and signal 7, signal 8, signal 9, and signal 10 on carrier 2 are at Over time overlap. In this case, if the QCL hypothesis information of the signal on carrier 1 and the QCL hypothesis information of the signal on carrier 2 are not the same, the UE cannot simultaneously receive signals on the two carriers at the same time.

Therefore, when the UE simultaneously receives at least two signals on multiple carriers at a time, when the QCL hypothesis information of the two signals is inconsistent, how to determine the QCL hypothesis information for receiving these signals is a technical problem that needs to be solved currently.

detailed description

The terms used in the embodiments of the present application are only used to explain the specific embodiments of the present application, and are not intended to limit the present application.

FIG. 2 shows a wireless communication system to which the present application relates. The wireless communication system can work in a high frequency band, is not limited to a Long Term Evolution (LTE) system, and can be a fifth generation mobile communication (the 5th generation, 5G) system, a new air interface (New Radio, NR) systems, Machine to Machine (M2M) systems, etc. As shown in FIG. 2, the wireless communication system 100 can include one or more network devices 101, one or more terminals 103, and a core network (not shown). among them:

The network device 101 can be a base station, and the base station can be used for communicating with one or more terminals, and can also be used for communicating with one or more base stations having partial terminal functions (such as a macro base station and a micro base station, such as an access point, Communication between). The base station may be a Base Transceiver Station (BTS) in a Time Division Synchronous Code Division Multiple Access (TD-SCDMA) system, or may be an evolved base station in an LTE system (Evolutional Node B). , eNB), and base stations in 5G systems, new air interface (NR) systems. In addition, the base station may also be an Access Point (AP), a Transmission Receive Point (TRP), a Central Unit (CU), or other network entity, and may include some of the functions of the above network entities. Or all features.

Terminals 103 may be distributed throughout wireless communication system 100, either stationary or mobile. In some embodiments of the present application, terminal 103 may be a mobile device, a mobile station, a mobile unit, an M2M terminal, a wireless unit, a remote unit, a terminal agent, a mobile client, and the like.

In the present application, the wireless communication system 100 is a multi-beam communication system. among them:

The network device 101 can be configured with a large-scale antenna array and utilize beamforming techniques to control the antenna array to form beams of different orientations. In order to cover the entire cell 107, the network device 101 needs to use a plurality of differently directed beams.

For example, in the downlink process, the network device 101 may sequentially transmit wireless signals (Reference Signals (RSs) and/or Synchronization Signal Blocks (SS blocks)) using different directional beams. It is called Beam scanning. At the same time, the terminal 103 measures the transmit beam to determine the signal quality of the transmit beam that the terminal 103 can receive. This process is called Beam measurement.

In a future communication system, the terminal 103 may be configured with an antenna array, or may convert different beams to transmit and receive signals. That is to say, in the wireless communication system 100, both the network device 101 and the terminal 103 may use multiple beams for communication. In the downlink transmission process, the manner in which the network device 101 sends the PDCCH to the terminal 103 may be as shown in FIG. 3A to FIG. 3D:

3A shows that network device 101 transmits a PDCCH to terminal 103 using one transmit beam (e.g., beam a), and terminal 103 receives the PDCCH using one receive beam (e.g., beam 1). In the scenario shown in Figure 3A, beam a is paired with beam 1.

3B shows that network device 101 transmits a PDCCH to terminal 103 using one transmit beam (e.g., beam a), and terminal 103 receives the PDCCH using a plurality of receive beams (e.g., beams 1, 3). In the scenario shown in Figure 3B, beam a is paired with beam 1 and beam a and beam 3 are paired.

3C shows that network device 101 transmits a PDCCH to terminal 103 using a plurality of transmit beams (e.g., beams a, b), and terminal 103 receives the PDCCH using a plurality of receive beams (e.g., beam 1, beam 3). In the scenario shown in Figure 3C, beam a is paired with beam 1 and beam b is paired with beam 3.

3D shows terminal 103 transmitting a PDCCH to terminal 103 using a plurality of transmit beams (eg, beams a, b) that receive PDCCH using the same receive beam (eg, beam 1). In the scenario shown in Figure 3D, beam a is paired with beam 1 and beam b is paired with beam 1.

Correspondingly, the four PDCCH transmission scenarios shown in FIG. 3A to FIG. 3D can also be applied to the scenario in which the network device 101 sends the PDSCH to the terminal 103, and details are not described herein again.

To facilitate the description, the transmit and receive beams of the network device may be referred to as a base station beam, including a base station transmit beam (or a base station transmit beam) and a base station receive beam. A network device can have multiple base station transmit beams and multiple base station receive beams. The transceiver beam of the terminal device is referred to as a terminal beam, and includes a terminal transmit beam (or a terminal transmit beam) and a terminal receive beam. A terminal device may have multiple terminal transmit beams, and multiple terminal receive beams.

The paired base station transmit beam and the terminal receive beam shown in Figures 3A-3D, and the terminal transmit beam and the base station receive beam are paired by a beam training procedure. Referring to FIG. 4, it is a beam training process involved in the present application. As shown in FIG. 4, e is a training process of a beam transmitted by a network device. The network device sends multiple beams, and the terminal measures multiple beams sent by the network device, and notifies the network device of the better ones of the multiple beams sent by the network device. Conversely, as shown in FIG. 4, d is a training process of a beam transmitted by the terminal, the terminal transmits multiple beams, and the network device measures multiple beams sent by the terminal, and notifies the better beam of the multiple beams sent by the terminal to terminal. Through the beam training process, the network device obtains N Beam Pairs (BPL) that are better in communication with the terminal. The beam pair BPL is <Bx, B'x>, where Bx represents a transmit beam of the network device, B'x represents a receive beam of the terminal, and <By, B'y>, where By represents the transmit beam of the terminal, B 'y stands for the receive beam of the network device. The network device uses the N BPLs for data transmission during subsequent and terminal communication. The preferred beam mentioned here refers to the channel quality information of the beam (for example, Reference Signal Received Power (RSRP), Channel Quality Indicator (CQI), etc.).

In this application, each base station receive beam corresponds to one base station transmit beam. Here, the base station receive beam corresponding to the base station transmit beam means that it has the same directivity. Optionally, the base station receive beam and its corresponding base station transmit beam may be the same beam, and the two may share the same transceiver. Optionally, the antenna port corresponding to the base station receive beam and its corresponding base station transmit beam may be a Quasi Co-location (QCL).

In this application, each terminal receiving beam corresponds to one terminal transmitting beam. Here, the terminal receiving beam corresponding to the terminal transmitting beam means: having the same directivity. Alternatively, the terminal receive beam and its corresponding terminal transmit beam may be the same beam, and the two may share the same transceiver. Optionally, the antenna port corresponding to the terminal receiving beam and its corresponding terminal transmitting beam may be QCL.

It should be noted that the beam mentioned in the present application may be characterized by reference signal resources or by QCL information.

This application relates to the concept of Quasi Co-location (QCL). The QCL can be used to assist in describing the receiving side beamforming information and receiving process of the user. The QCL information may include some spatial characteristic parameters such as a departure angle related parameter, an Azimuth angle of Departure (AoD), a Zenith angle of Departure (ZoD), and an Azimuth angle spread. Of Departure (ASD), Zenith angle spread of Departure (ZSD), or angle-dependent parameters, Azimuth angle of Arrival (AoA), vertical angle of departure (Zenith angle of Arrival, ZoA) ), Azimuth angle spread of Arrival (ASA), Zenith angle spread of Arrival (ZSA), and the like. These spatial characteristic parameters describe the spatial channel characteristics between the reference signal (RS) antenna ports. The QCL information may also include a Receive (RX) parameter. In addition, the QCL information includes but is not limited to at least one of the following parameters: delay spread, Doppler spread, Doppler shift, average gain, and average. delay. Optionally, the spatial characteristic parameter included in the QCL may also be other parameters than the foregoing parameters, which are not limited herein. In order to save the QCL indication overhead of the network device to the terminal, a candidate prior art is that the QCL sent by the network device to the terminal indicates the N channel state information reference signals (CSI) that are reported before the terminal is limited. -RS) One of the measured transmit and receive beam pairs is QCL-compliant. That is, the receive beam of the modulation reference signal (DMRS) of the current data is the same as one of the N transmit/receive beam pairs based on the CSI-RS measurement reported by the terminal. For example, the terminal selects a plurality of the CSI-RSs of the plurality of beams sent by the network device, for example, four beams, and reports the four beam measurement information to the network device. The beam measurement information, that is, the beam status information (BSI), includes the reference signal resource index and the reference signal received power (RSRP) of the beam. The QCL sent by the network device to the terminal indicates that the third CSI-RS of the four CSI-RS-based transmit/receive beam pairs reported by the terminal satisfies the QCL relationship, and the terminal adopts the receive beam receiving network corresponding to the third CSI-RS. PDSCH delivered by the device.

Signals on different carriers can correspond to different QCL hypothesis information. For example, assume that the transmission signal of the communication device includes A ₁ and A ₂ , and the two signals are transmitted on carrier 1 and carrier 2, respectively, and the two signals overlap in the receiving time, for example, signal A ₁ is FIG. 1A. signals transmitted on a carrier signal 1 in the signal a ₂ in FIG. 1A is a transmission on the carrier 1 3. Signals A ₁ and A ₂ each correspond to one QCL hypothesis information. For example, a signal with signal A ₁ B ₁ satisfies the relationship QCL, the communications device uses the received signal corresponding to the beam B ₁ A ₁ reception signal. Signal and the signal B ₂ A ₂ satisfy the relationship QCL, the communication device receives the reception beam using the signal corresponding to the A ₂ B _2. If the QCL hypothesis information of the signal A ₁ and the signal A _{2 is} the same, the communication device receives the signal A ₁ and the signal A ₂ by using the same beam. If the QCL hypothesis information of the signal A ₁ and the signal A ₂ are different, the communication device adopts different beam reception. Signal A ₁ and signal A ₂ . The same QCL of the two signals means that the receiving beams of the two signals are the same, and the QCL of the two signals is different, that is, the receiving beams of the two signals are different. The case of multiple signals is similar to the case of two signals, and will not be described here. In the present application, QCL, QCL information, and QCL hypothesis information are the same concept. The QCL hypothesis information may be indicated by the network device to the communication device (eg, the terminal), or may be predefined on the network device side and the communication device side. The QCL hypothesis information of the signal A is the signal B, or the signal A and the signal B are the parameters satisfying the QCL hypothesis. The communication device refers to the spatial reception filtering parameter of the signal B when receiving the signal A. The signal referred to herein (e.g., signal B) is typically a signal that precedes the target signal (e.g., signal A). This QCL hypothesis, which defines the spatial reception information of the communication device, is also called QCL hypothesis type D. The type of the signal to be referred to may be a reference signal or a control channel or a common signal, etc., and is not specifically limited herein.

In an NR system or a future evolved wireless communication system, a communication device can transmit data on multiple Carrier Carriers (CCs) or multiple Broadband Blocks (BWPs) of one carrier. The communication device may be a terminal or a network device. One carrier can be divided into at least two BWPs according to the frequency domain. In the current standard, different signals on the same carrier can correspond to different QCL hypothesis information, and different signals on different carriers can also correspond to different QCL hypothesis information. The QCL hypothesis information may be pre-configured by the network device or determined in a predefined manner. When N (N is a positive integer greater than or equal to 2) transmission signals respectively correspond to different QCL hypothesis information, it is necessary to determine one or more default QCL hypothesis information to receive the N transmission signals. In this application, the default QCL hypothesis information may be determined according to at least one of a carrier index, a system parameter, a signal type, and a wireless network identification type of the N transmission signals. For convenience of description, in the following embodiments, the default QCL hypothesis information is named as the first QCL hypothesis information. The manner in which the default QCL hypothesis information is determined will be described in detail in the following method embodiments.

It should be noted that the present application is applicable to a scenario in which multiple carriers or multiple BWPs are used, and is also applicable to a scenario in which a plurality of signals are frequency-multiplexed and multiplexed on one carrier or one BWP, which is not specifically limited herein. In the following embodiments, the carrier is taken as an example for description. The implementation in the scenario of the BWP is similar and will not be described again.

Based on the foregoing embodiments of the wireless communication system 100, the terminal 200, and the network device 300, the embodiment of the present application provides a signal receiving method. FIG. 7 is a schematic flowchart diagram of a signal receiving method provided by the present application. As shown in FIG. 7, the method includes the following steps.

S701. The first communications device determines first quasi co-location (QCL) hypothesis information according to the first parameter of the N transmission signals, where the first parameter includes a carrier index, a system parameter, a signal type, a radio network identifier type, a time domain type, or a resource. At least one of the indexes, N being a positive integer greater than or equal to 2.

At least one of the following may refer to any one or any combination of a carrier index, a system parameter, a signal type, a wireless network identification type, or a time domain type or a resource index.

In the embodiment of the present invention, when the QCL hypothesis information of the N transmission signals that the first communication device needs to receive is not completely the same, the first communication device needs to determine one or more QCL hypothesis information. Generally, only one type of QCL hypothesis information needs to be determined. In the following embodiment, a QCL hypothesis information is mainly taken as an example for description. Wherein, the QCL hypothesis information of the N transmission signals is not completely the same, that is, the QCL hypothesis information of the at least two transmission signals in the N transmission signals is different. Optionally, the first quasi co-location hypothesis information determined by the first communications device may be one of quasi co-location hypothesis information of the N transmit signals.

It should be noted that the first communication device can know which signals need to be acquired on which carriers in advance. For example, if the first communication device is a terminal, the terminal can go to the corresponding time-frequency resource according to the configuration of the network device (such as the base station). The corresponding channel or signal is received. Alternatively, the configuration may be indicated by the network device to the terminal through semi-static signaling, or may be sent to the terminal by the network device through dynamic scheduling information.

It should be noted that, for each transmission signal, the network device is configured or associated with a carrier index, a system parameter, and a signal type. In the embodiment of the present invention, the system parameters may include, but are not limited to, SCS. The transmission signal is transmitted on a carrier corresponding to the carrier index configured by the network device. For a channel or a signal of a physical downlink shared channel (PDSCH), a physical uplink shared channel (PUSCH), and a physical downlink control channel (PDCCH), the network device It is also configured with a wireless network ID. For example, the types of radio network identifiers corresponding to the PDSCH include, but are not limited to, the following: Paging-Radio Network Tempory Identity (P-RNTI), System Information-Wireless Network Temporary Identity (System Information-Radio Network) Tempory Identity, SI-RNTI, RACH Response-Radio Network Tempory Identity (RA-RNTI), Scheduled Scheduling-Radio Network Tempory Identity (CS-) RNTI), Cell-Radio Network Tempory Identity (C-RNTI).

In one implementation, the N transmission signals are carried on M carriers, and M is a positive integer less than or equal to N. If the system parameters corresponding to the M carriers are not completely the same, the first communication device determines the quasi-co-location hypothesis information of the transmission signal on the carrier with the smallest system parameter among the M carriers as the first quasi co-location hypothesis information. Taking M equal to 2 as an example, the SCS corresponding to carrier 1 is 15 kHz, and the SCS corresponding to carrier 2 is 60 kHz. The SCS of 15 kHz is used as a reference. At a certain moment i, the signal transmitted on carrier 1 is PDSCH. The signals transmitted on carrier 2 are CSI-RS, PDCCH and PDSCH. In this case, to ensure that the PDSCH on carrier 1 can be completely received based on a QCL hypothesis, the first communication device can use the QCL hypothesis information of the PDSCH on carrier 1 as the above. The first QCL assumes information to receive a plurality of channels or signals on carrier 1 and carrier 2 in accordance with the QCL hypothesis information of the PDSCH on carrier 1. In the NR system, the system parameter is numerology, and numerology is usually characterized by SCS. Therefore, the system parameters of the two carriers are the same, that is, the SCSs of the two carriers are the same. The system parameters of the two carriers are different, that is, the SCS of the two carriers is different. In the future evolution of the communication system, the system parameters may also be characterized as other parameters, which are not specifically limited in this application.

The system parameters corresponding to the M carriers are not completely the same, that is, the system parameters of the at least two carriers in the M carriers are different. Determining the QCL hypothesis information according to the system parameters of the N transmission signals on the M carriers, and using the QCL hypothesis information of the transmission signal corresponding to the minimum system parameter as the first quasi co-location hypothesis information, each carrier of the M carriers can be guaranteed Each of the transmitted signals can be completely received based on a QCL hypothesis, thereby improving the reception performance of the N transmitted signals.

In another implementation manner, the N transmission signals are carried on the M carriers. If the system parameters corresponding to the M carriers are the same, the first communication device transmits the signal on the carrier with the smallest carrier index among the M carriers. The quasi co-location hypothesis information is determined as the first quasi co-location hypothesis information. When the transmission signals on the M carriers have no obvious priority, the quasi-co-location hypothesis information of the transmission signal on the carrier with the minimum carrier index is always used as the first quasi co-location hypothesis information, which can reduce the reception of the communication device. the complexity.

Taking M equal to 2 as an example, the carrier index of carrier 1 is 0, and the carrier index of carrier 2 is 1. At a certain moment i, the signal transmitted on carrier 1 is PDSCH, and the signal transmitted on carrier 2 is CSI. -RS, PDCCH, and PDSCH, the first communication device may use the QCL hypothesis information of the PDSCH on the carrier 1 as the first QCL hypothesis information, thereby receiving the carrier 1 and the carrier 2 according to the QCL hypothesis information of the PDSCH on the carrier 1. Multiple channels or signals.

In another implementation manner, the N transmission signals are carried on the M carriers. If the system parameters corresponding to the M carriers are the same, the first communication device uses the quasi-common of the transmission signals on the main carriers of the M carriers. The address hypothesis information is determined as the first quasi co-location hypothesis information. Generally, the transmission signal on the primary carrier is more important than the transmission signal on other carriers, and the control channel on the primary carrier can schedule traffic channels on other carriers across carriers. Therefore, the transmission signal on the primary carrier can maximize M. Performance of N transmitted signals on one carrier.

Taking M equal to 2 as an example, carrier 1 is the primary carrier. At a certain time i, the signal transmitted on carrier 1 is PDSCH, and the signal transmitted on carrier 2 is CSI-RS, PDCCH and PDSCH, then the first communication The device may use the QCL hypothesis information of the PDSCH on the carrier 1 as the first QCL hypothesis information, so as to receive multiple channels or signals on the carrier 1 and the carrier 2 according to the QCL hypothesis information of the PDSCH on the carrier 1.

In another implementation, if the N transmission signals include a common signal, the first communication device determines the quasi co-location assumption information of the common signal as the first quasi co-location hypothesis information. In the present application, the common signal includes a sync signal block. The synchronization signal block is a synchronization signal, an abbreviation of a broadcast channel block (a synchronization signal block includes a synchronization signal and a broadcast channel block), and the synchronization signal block specifically includes a primary synchronization signal, a secondary synchronization signal, a demodulation reference signal of a broadcast channel and a broadcast channel. At least one of them. The public signal may also include a broadcast traffic channel, such as a PDSCH carrying system information, a PDSCH carrying a paging message, or a PDSCH carrying a random access response. Optionally, the public signal may also be any other broadcast type of signal, which is not specifically limited herein.

Specifically, if the N transmission signals include one common signal, the first communication device determines the quasi-co-location hypothesis information of the common signal as the first quasi co-location hypothesis information.

If the P common signals are included in the N transmission signals and the P common signals are carried on the O carriers, the first communication device compares the quasi-co-location hypothesis information of the transmission signals on the carriers corresponding to the primary carrier index in the O carriers. It is determined as the first quasi co-location hypothesis information, P is a positive integer less than or equal to N and greater than or equal to 2, and O is a positive integer less than or equal to P.

Or, if the P common signals are included in the N transmission signals and the P common signals are carried on the O carriers, the first communication device assumes a quasi co-location assumption of the transmission signal on the carrier with the smallest carrier index among the O carriers. The information is determined as the first quasi co-location hypothesis information, P is a positive integer less than or equal to N and greater than or equal to 2, and O is a positive integer less than or equal to P.

That is to say, when the common signals in the N transmission signals are respectively carried on a plurality of carriers, it is further required to further combine a carrier index to select one carrier from the plurality of carriers, thereby further transmitting signals on the finally selected carrier. The quasi co-location hypothesis information is determined as the first quasi co-location hypothesis information.

In another implementation, the N transmission signals are carried on M carriers, and M is a positive integer less than or equal to N. If the system parameters corresponding to the M carriers are not completely the same and the carrier with the smallest system parameter among the M carriers includes K, the first communication device transmits the signal with the highest priority of the signal type on the carrier with the smallest K system parameters. The quasi co-location hypothesis information is determined as the first quasi co-location hypothesis information. Higher priority signals are usually more important, and this implementation ensures optimal performance of the more important transmitted signals, maximizing overall system performance. For example, referring to FIG. 8B, the SCS corresponding to carrier 1 and carrier 3 is 15 kHz, and the SCS corresponding to carrier 2 is 60 kHz, the signal transmitted on carrier 1 is PDSCH, and the signals transmitted on carrier 2 are CSI-RS, PDCCH, and PDSCH. The signal transmitted on carrier 3 is RS, and the carrier with the smallest system parameter includes carrier 1 and carrier 3. The QCL hypothesis information of the PDSCH with high signal type is selected as the first QCL hypothesis information based on the signal types of the PDSCH and the RS. Thus, multiple channels or signals on carrier 1, carrier 2, and carrier 3 are received in accordance with the QCL hypothesis information of the PDSCH on carrier 1.

That is to say, when the carrier with the smallest system parameter includes multiple, it is further necessary to further combine the signal type on the carrier to select one of the plurality of transmission signals carried on the plurality of carriers, thereby further selecting the transmission. The quasi co-location hypothesis information of the signal is determined as the first quasi co-location hypothesis information. When a transmission signal having a high signal type and other signals are scheduled to be transmitted in the same OFDM symbol, the QCL hypothesis information of the transmission signal having a high signal type is preferentially received as a default QCL hypothesis information to receive a plurality of signals.

In another implementation, the N transmission signals are carried on M carriers, and M is a positive integer less than or equal to N. If the system parameters corresponding to the M carriers are not identical and the carrier with the smallest system parameter among the M carriers includes K, the first communication device transmits the signal on the carrier with the smallest carrier index among the carriers with the smallest K system parameters. The quasi co-location hypothesis information is determined as the first quasi co-location hypothesis information, M is a positive integer less than or equal to N, and K is a positive integer less than or equal to M. When the transmission signals on the K carriers have no obvious priority, the quasi-co-location hypothesis information of the transmission signal on the carrier with the minimum carrier index is always used as the first quasi-co-location hypothesis information, which can reduce the reception of the communication device. the complexity. For example, referring to FIG. 8B, the SCS corresponding to carrier 1 and carrier 3 is 15 kHz, and the SCS corresponding to carrier 2 is 60 kHz, the signal transmitted on carrier 1 is PDSCH, and the signals transmitted on carrier 2 are CSI-RS, PDCCH, and PDSCH. The signal transmitted on carrier 3 is RS, and the carrier with the smallest system parameter includes carrier 1 and carrier 3. Based on the carrier index of carrier 1 and carrier 3, the QCL hypothesis information of PDSCH on carrier 1 with small carrier index is selected as The first QCL hypothesis information is such that multiple channels or signals on carrier 1, carrier 2, and carrier 3 are received according to the QCL hypothesis information of the PDSCH on carrier 1.

That is to say, when the carrier with the smallest system parameter includes multiple, it is further necessary to further combine the carrier index to select one carrier from the multiple carriers, and then determine the quasi-co-location hypothesis information of the transmission signal on the finally selected carrier as The first quasi co-location hypothesis information.

In another implementation, the N transmission signals are carried on M carriers, and M is a positive integer less than or equal to N. If the system parameters corresponding to the M carriers are not identical, and the carrier with the smallest system parameter among the M carriers includes K, the first communication device transmits the signal on the carrier corresponding to the primary carrier index of the carrier with the smallest system parameter. The quasi co-location hypothesis information is determined as the first quasi co-location hypothesis information. Generally, the transmission signal on the primary carrier is more important than the transmission signal on other carriers, and the control channel on the primary carrier can schedule traffic channels on other carriers across carriers. Therefore, the transmission signal on the primary carrier can maximize M. Performance of N transmitted signals on one carrier. For example, referring to FIG. 8B, the SCS corresponding to carrier 1 and carrier 3 is 15 kHz, and the SCS corresponding to carrier 2 is 60 kHz, the signal transmitted on carrier 1 is PDSCH, and the signals transmitted on carrier 2 are CSI-RS, PDCCH, and PDSCH. The signal transmitted on the carrier 3 is the RS, and the carrier with the smallest system parameter includes the carrier 1 and the carrier 3. Then, the QCL hypothesis information of the PDSCH on the primary carrier 1 is selected as the first QCL hypothesis information, so that the PDSCH on the carrier 1 is used. The QCL assumes that the information is to receive multiple channels or signals on Carrier 1, Carrier 2 and Carrier 3.

That is to say, when the carrier with the smallest system parameter includes multiple, it is further necessary to further combine the carrier index to select one carrier from the multiple carriers, and then determine the quasi-co-location hypothesis information of the transmission signal on the finally selected carrier. Assume information for the first quasi co-location.

In another implementation, the N transmission signals are carried on M carriers, and M is a positive integer less than or equal to N. If the system parameters corresponding to the M carriers are not completely the same and the transmission signals on the carrier with the smallest system parameter among the M carriers include L, the first communication device transmits the signal with the highest priority of the signal type in the L transmission signals. The quasi co-location hypothesis information is determined as the first quasi co-location hypothesis information, and L is a positive integer less than or equal to N. Higher priority signals are usually more important, and this implementation ensures optimal performance of the more important transmitted signals, maximizing overall system performance. For example, referring to FIG. 8C, the SCS corresponding to carrier 1 is 15 kHz, and the SCS corresponding to carrier 2 is 60 kHz, the signals transmitted on carrier 1 are CSI-RS and PDSCH, and the carrier 1 with the smallest system parameter includes two transmission signals. Based on the signal types of the CSI-RS and the PDSCH, the QCL hypothesis information of the PDSCH with a high signal type is selected as the first QCL hypothesis information, so that the carrier 1 and the carrier 2 are received according to the QCL hypothesis information of the PDSCH on the carrier 1. Multiple channels or signals.

That is to say, when the transmission signal on the carrier with the smallest system parameter includes multiple, it is further necessary to further combine the signal type on the carrier to select one transmission signal from the plurality of transmission signals, thereby further selecting the transmission signal. The quasi co-location hypothesis information is determined as the first quasi co-location hypothesis information.

In another implementation manner, if the signal types corresponding to the N transmission signals include at least two types, the first communication device determines the quasi co-location assumption information of the transmission signal with the highest priority of the signal types in the N transmission signals as The first quasi co-location hypothesis information. That is to say, the first communication device selects the transmission signal with the highest priority of one signal type from the N transmission signals according to the priority of the signal type, and then the quasi-common of the transmission signal with the highest priority of the finally selected signal type. The address hypothesis information is determined as the first quasi co-location hypothesis information. This implementation also ensures optimal performance of the more important transmitted signals, thereby maximizing overall system performance.

Optionally, the priority of the signal type can be sorted according to the following rules. The priority of the control signal is greater than or equal to the priority of the traffic signal. The priority of the traffic signal is greater than or equal to the priority of the reference signal. The priority of the common signal is greater than or equal to the priority of the dedicated signal. A signal with a high priority of service has a priority greater than or equal to a priority of a signal with a lower priority of the service. A signal that does not require a network device (such as a base station) to perform scheduling control has a priority greater than or equal to a priority of a signal that requires network equipment to perform scheduling control. A signal with a small system parameter (such as SCS) has a priority greater than or equal to the priority of a signal with a large system parameter.

Optionally, for a Synchronous Signal Block (SSB), a Physical Downlink Control Channel (PDCCH), a Physical Downlink Shared Channel (PDSCH), and a Reference Signal (RS) For these downlink signals, the priority relationship may be one or more of the priority relationships as shown in Table 1 below. For example, if there is no second line, only the third line and the fourth line, the following priority relationship still holds.

Table 1

优先级priority	信号类型signal type

22	广播(Broadcast)的PDCCH/PDSCHBroadcast PDCCH/PDSCH
33	单播(unicast)的PDCCH Unicast PDCCH
44	单播的PDSCHUnicast PDSCH
55	RSRS

In Table 1, the smaller the priority number, the higher the priority of the corresponding signal type.

Further, different reference signals (RSs) can correspond to different priorities. For example, a Channel State Information Reference Signal (CSI-RS) for performing Radio Link Monitor (RLM), and a CSI-RS for Beam Management (BM) CSI-RS, Phase Tracking Reference Signal (PTRS), and Tracking Reference Signal (TRS) for channel state information (CSI) detection In other words, the priority relationship may be one or more of the priority relationships as shown in Table 2 below. For example, if there is no second line, only the third line and the fourth line, the following priority relationship still holds.

Table 2

优先级priority	信号类型signal type
11	CSI-RS for RLMCSI-RS for RLM
22	CSI-RS for BMCSI-RS for BM
33	CSI-RS for CSICSI-RS for CSI
44	PTRS、TRSPTRS, TRS

In Table 2, the smaller the priority number, the higher the priority of the corresponding signal type.

Optionally, at a certain transmission moment, if the signal types on multiple carriers or multiple bandwidth blocks are the same, the priority of the signal may be distinguished according to the time domain type or time domain behavior of the signal, for example, at a certain transmission moment, When the signals on multiple carriers or multiple bandwidth blocks are the same as the CSI-RS, the CSI may be determined according to the time domain type of the CSI-RS, that is, the periodic CSI-RS, the aperiodic CSI-RS, or the semi-static configuration CSI-RS. The RS of the RS assumes a priority, and one candidate priority order is: the aperiodic CSI-RS is greater than or equal to the semi-static CSI-RS, and the semi-static CSI-RS is greater than or equal to the periodic CSI-RS. Similarly, at a certain transmission moment, when the signals on multiple carriers or multiple bandwidth blocks are the same as the SRS, the SRS may be determined according to the time domain type of the SRS, that is, the periodic SRS, the aperiodic SRS, or the semi-static configuration SRS. The QCL assumes a priority, and the candidate priority ordering is: the non-periodic SRS is greater than or equal to the semi-static configuration SRS, and the semi-static SRS is greater than or equal to the periodic SRS, etc., of course, there is no other sorting manner, which is not specifically limited herein.

In another implementation manner, if the signal types on multiple carriers or multiple bandwidth blocks are the same at a certain transmission time, the priority of the signals may be distinguished according to the resource index numbers of the signals, for example, at a certain transmission time. When the signals on multiple carriers or multiple bandwidth blocks are the same as the CSI-RS, the QCL hypothesis priority of the CSI-RS may be determined according to the resource index numbers of the multiple CSI-RSs, and a candidate method for determining the default QCL hypothesis It is the default QCL hypothesis of CSI-RS with the smallest resource index number as the common QCL hypothesis of these CSI-RSs. Similarly, at a certain transmission moment, when signals on multiple carriers or multiple bandwidth blocks are the same as SRS, the priority of the signals can be distinguished according to the resource index numbers of the signals, for example, at a certain transmission moment, when When the signals on the carrier or multiple bandwidth blocks are the same as the SRS, the QCL hypothesis priority of the SRS may be determined according to the resource index numbers of the multiple SRSs. A candidate for determining the default QCL hypothesis is to default to the smallest resource index number. The QCL hypothesis of SRS is assumed as a common QCL for these SRSs.

For a random access channel (RACH), a physical uplink control channel (PUCCH), a physical uplink shared channel (PUSCH), and a sounding reference signal (SRS) For several uplink signals, the priority relationship may be one or more of the priority relationships as shown in Table 3 below. For example, if there is no second line, only the third line and the fourth line, the following priority relationship still holds.

table 3

优先级priority	信号类型signal type
11	RACHRACH
22	PUCCH PUCCH
33	PUSCH PUSCH
44	SRSSRS

In Table 3, the smaller the priority number, the higher the priority of the corresponding signal type.

Further, different SRSs may correspond to different priorities. For example, SRS for Beam Management (BM), SRS for Non-Codebook Based (NCB) transmission, and SRS for Codebook Based (CB) transmission. For the SRS, the priority relationship may be one or more of the priority relationships as shown in Table 4 below. For example, if there is no line 1, only the second line and the third line, the following priority relationship still holds.

Table 4

优先级priority	信号类型signal type
11	SRS for BMSRS for BM
22	SRS for NCBSRS for NCB
33	SRS for CBSRS for CB

In Table 4, the smaller the priority number, the higher the priority of the corresponding signal type. In another implementation manner, if the signal types corresponding to the N transmission signals are the same, the first communication device uses a quasi-common transmission signal with the highest priority of the radio network identification type among the N transmission signals. The address hypothesis information is determined as the first quasi co-location hypothesis information. The higher priority signals of the wireless network identification type are usually more important. This implementation ensures that the performance of the more important transmission signals is optimal, thereby maximizing the performance of the entire system.

Optionally, the priority of the wireless network identification type may be sorted according to the following rules. The priority of the wireless network identifier of the downlink signal is greater than or equal to the priority of the wireless network identifier of the uplink signal. The priority of the wireless network identifier of the signal with high service priority is greater than or equal to the priority of the wireless network identifier of the signal with low service priority. The priority of the wireless network identifier of the signal that does not require the network device (such as the base station) to perform scheduling control is greater than or equal to the priority of the wireless network identifier of the signal that requires the second communication device to perform scheduling control. The priority of the wireless network identity of the public signal is greater than or equal to the priority of the wireless network identity of the dedicated signal.

Optionally, the Radio Network Tempory Identity (RNTI) type corresponding to the PDSCH includes but is not limited to the following: Paging-Radio Network Tempory Identity (P-RNTI), system information - System Information-Radio Network Tempory Identity (SI-RNTI), random access response-Radio Network Tempory Identity (RA-RNTI), setting scheduling-wireless network temporary identifier (Configued Scheduling-Radio Network Tempory Identity, CS-RNTI), Cell-Radio Network Tempory Identity (C-RNTI). The priority relationship of the foregoing RNTI types may be one or more of the priority relationships as shown in Table 5 below. For example, if there is no line 1, only the second line and the third line, the following priority relationship still holds.

table 5

优先级priority	RNTI类型RNTI type
11	P-RNTI、SI-RNTI、RA-RNTIP-RNTI, SI-RNTI, RA-RNTI
22	CS-RNTICS-RNTI
33	C-RNTIC-RNTI

In Table 5, the smaller the priority number, the higher the priority of the corresponding RNTI type.

Optionally, the RNTI type corresponding to the PDCCH includes but is not limited to the following: P-RNTI, SI-RNTI, RA-RNTI, Interruption-Radio Network Tempory Identity (INT-RNTI), and time Slot Format Indicator-Radio Network Tempory Identity (SFI-RNTI), CS-RNTI, C-RNTI, Semi-Static Channel Status Information-Semi Persistent Channel State Information-Radio Network Tempory Identity, SP-CSI-RNTI), Transmission Power Command-Physical Uplink Shared Channel-Transmission Power Command PUSCH-Radio Network Tempory Identity (TPC-PUSCH-RNTI), Transmission Power Command-Probing Reference Signal-Wireless Transmission Power Command SRS-Radio Network Tempory Identity (TPC-SRS-RNTI). The priority relationship of the foregoing RNTI types may be one or more of the priority relationships as shown in Table 6 below. For example, if there is no second line, only the third line and the fourth line, the following priority relationship still holds.

In Table 6, the smaller the priority number, the higher the priority of the corresponding RNTI type.

Optionally, the Radio Network Tempory Identity (RNTI) type corresponding to the PUSCH includes, but is not limited to, the following: CS-RNTI, C-RNTI, and SP-CSI-RNTI. The priority relationship of the foregoing RNTI types may be one or more of the priority relationships as shown in Table 7 below. For example, if there is no line 1, only the second line and the third line, the following priority relationship still holds.

Table 7

优先级priority	RNTI类型RNTI type
11	CS-RNTICS-RNTI

33	SP-CSI-RNTISP-CSI-RNTI

In Table 7, the smaller the priority number, the higher the priority of the corresponding RNTI type.

Optionally, when determining the first QCL hypothesis information, the first QCL hypothesis information may be determined by referring to one or more priority rules as shown in Table 8 or Table 9 below.

Table 8

Table 9

In the foregoing Table 8 or Table 9, if there is a priority of 1, the default QCL hypothesis is first determined according to the priority 1. When the carrier with the smallest SCS determined based on the priority 1 is a plurality of carriers, the priority 2 is further Determine the default QCL assumption. The control resource set (CORESET) is a time-frequency resource in the control area.

The "network device configuration default QCL assumption" in the above table means that the network device performs scheduling of multiple signals. For example, when there is an SSB, the UE assumes that there is no other signal that the QCL assumes different and the SSB is simultaneously transmitted at one time. . That is, when other signals and SSBs are transmitted simultaneously, the default QCL assumptions for both are the same.

Optionally, when the type of the RNTI of the multiple signals is P-RNTI/SI-RNTI/RA-RNTI, the QCL hypothesis information of the transmission signal on the carrier with the smallest carrier or carrier index may also be used as the first QCL. Assumed information.

The above multiple implementation manners may also be combined in any combination. For example, the first communication device first selects QCL hypothesis information of the transmission signal on the carrier with the smallest system parameter according to the system parameter of the carrier, and if the transmission signal on the carrier with the smallest system parameter includes multiple Further selecting a transmission signal having the highest priority of the signal type from the plurality of transmission signals, and if the transmission signal having the highest priority of the signal type includes a plurality, further transmitting signals having the highest priority from the plurality of signal types The transmission signal with the highest priority of the RNTI is selected, and the QCL hypothesis information of the finally selected transmission signal is determined as the first QCL hypothesis information. Or the first communication device selects a transmission signal on a carrier with the smallest system parameter according to the system parameter of the carrier, and if the transmission signal on the carrier with the smallest system parameter includes multiple, further selects a carrier from the plurality of carriers with the smallest system parameters. The carrier having the common signal further determines the QCL hypothesis information of the transmission signal on the finally selected carrier as the first QCL hypothesis information.

It should be understood that when the foregoing multiple implementation manners are combined, the order of the multiple implementation manners may be arbitrarily adjustable. For example, the first communication device may also first assume the QCL hypothesis of the transmission signal with the highest priority according to the signal type of the multiple transmission signals. Information, if there are multiple transmission signals with the highest priority and the transmission signals are located on different carriers, further select the QCL hypothesis information of the transmission signal on the carrier with the smallest system parameter according to the system parameter of the carrier, and the finally selected transmission The QCL hypothesis information of the signal is determined as the first QCL hypothesis information.

Alternatively, the first communication device may firstly determine the priority of the signal type from the plurality of transmission signals according to the QCL hypothesis information of the transmission signal on the primary carrier of the plurality of transmission signals. The highest-level transmission signal, if the signal type has the highest priority transmission signal, and further selects the transmission signal with the highest RNTI priority from the highest priority transmission signals of the multiple signal types, and finally selects the transmission. The QCL hypothesis information of the signal is determined as the first QCL hypothesis information.

Alternatively, the first communication device may firstly transmit the signal with the highest priority according to the signal type of the plurality of transmission signals, and if the transmission signal with the highest priority of the signal type includes multiple, the priority of the plurality of signal types is further highest. The transmission signal has the highest RNTI priority transmission signal. If the RNTI has the highest priority transmission signal, the QCL hypothesis information of the transmission signal on the main carrier of the plurality of transmission signals is further determined as the first QCL hypothesis information.

In addition, the determining, by the first communication device, the QCL hypothesis information of the plurality of transmission signals is further related to the capability of the first communication device, such as the capability of the multi-antenna panel, etc., when the first communication device has multiple antenna panels, It can receive these multiple signals with different QCL hypothesis information on different antenna panels at one time. Therefore, the QCL hypothesis information determined by the first communication device may include at least two. Here, no specific limitation is made.

It should be noted that, in the foregoing implementation manners, the first communications device may be a terminal or a network device.

Optionally, in order to further improve the flexibility of the QCL hypothesis setting of multiple signals on different carriers, the network device may indicate the QCL hypothesis information corresponding to a certain one of the multiple transmission signals by an explicit or implicit manner. To be used as the first QCL hypothesis information, the terminal determines to determine the QCL hypothesis information of a certain transmission signal as the first QCL hypothesis information according to the indication of the network device.

Specifically, the first communications device receives the carrier index sent by the second communications device. Here, the first communications device may be a terminal, and the second communications device may be a network device. The first communication device determines the quasi co-location hypothesis information of the first transmission signal on the carrier corresponding to the carrier index sent by the second communication device as the first quasi co-location hypothesis information. That is to say, the network device configures the terminal as the carrier of the default QCL, and the terminal uses the QCL hypothesis information of the first transmission signal on the carrier of the default QCL configured by the network device as the first QCL hypothesis information. Specifically, the manner in which the first communications device receives the carrier index sent by the second communications device may be: the first communications device receives Radio Resource Control (RRC) signaling and downlink control information sent by the second communications device ( Downlink control information (DCI), which carries a carrier index in the RRC signaling or DCI. For example, at a certain time i, when the base station has a demand for scanning a beam on carrier 1, it configures carrier 1 to the UE for the QCL of the UE based on the first transmission signal on carrier 1 (assumed to be CSI-RS). It is assumed that as a default hypothesis, multiple signals on multiple carriers are received.

Or the first communication device receives the carrier index and the signal type index sent by the second communication device, and the first communication device assumes the quasi-co-location assumption of the transmission signal corresponding to the signal type index on the carrier corresponding to the carrier index sent by the second communication device. The information is determined as the first quasi co-location hypothesis information. That is to say, the network device configures the carrier and signal of the default QCL for the terminal, and the terminal uses the QCL hypothesis information of the transmission signal corresponding to the signal type index on the carrier of the default QCL configured by the network device as the first QCL hypothesis information. Specifically, the manner in which the first communications device receives the carrier index and the signal type index sent by the second communications device may be: the first communications device receives the Radio Resource Control (RRC) signaling sent by the second communications device, and or Downlink control information (DCI), which carries a carrier index and a signal type index in the RRC signaling or DCI. For example, at a certain time i, when the base station has a demand for scanning a beam on carrier 1, it configures carrier 1 and CSI-RS for BM to the UE for the UE to use the QCL assumption of CSI-RS on carrier 1 as a default. It is assumed that multiple signals on multiple carriers are received.

Or the first communication device receives the system parameter index and the carrier index sent by the second communication device, and the first communication device uses the system parameter index sent by the second communication device and the quasi co-location assumption information of the transmission signal on the carrier corresponding to the carrier index. Determined as the first quasi co-location hypothesis information. In the NR system, an SCS index may correspond to multiple carrier indexes, where the carrier index may be an absolute carrier index value or a relative carrier index value. For example, the absolute carrier index corresponding to SCS1 is CC1, CC2, CC3, CC7, the relative carrier index is 0, 1, 2, 3. The absolute carrier index corresponding to SCS2 is CC4, CC5, CC6, and CC8, and the relative carrier index is 0, 1, 2, and 3. At a certain time i, when the base station has a scanning beam requirement on carrier 1 (absolute index CC1), it configures SCS1 and carrier 1 to the UE for the QCL hypothesis of the UE based on the transmission signal on carrier 1 inside SCS1. As a default assumption, multiple signals on multiple carriers are received.

S702: The second communications device sends U transmission signals, where the first communications device receives, according to the first quasi co-location hypothesis information, U transmission signals, where the U transmission signals are part of the N transmission signals. Or all, U is a positive integer less than or equal to N.

In the embodiment of the present invention, U may be equal to N, that is, the second communication device sends the N transmission signals, and the first communication device receives the N transmission signals according to the first quasi co-location assumption information at the first moment.

Or, U may be smaller than N, that is, the second communication device sends a part of the N transmission signals, and the first communication device receives, according to the first quasi co-location assumption information, a part of the N transmission signals at the first moment. signal.

In the embodiment of the present invention, the first moment may refer to a momentary position or an instantaneous time during the communication transmission, and may also be characterized as a time unit, which may be a subframe, a slot, and a symbol ( Symbol) equal time domain unit. For example, the first moment may be characterized as one or more Orthogonal Frequency Division Multiplexing (OFDM) symbols, and the first moment may also be characterized as one or more time slots, and the first moment may also be characterized as one Or multiple subframes. In the embodiment of the present invention, the N transmission signals have an overlap in receiving time. Since it is necessary to receive multiple signals on multiple carriers at the same time, although they need to be received at the same time in time,

In the embodiment of the present invention, the subframes/slots/symbols corresponding to different signals may be inconsistent. Therefore, multiple signals that need to be received at the same time may also be understood as signals that need to be received at a certain time point or time period. In the embodiment of the present invention, at least two of the N transmission signals have an intersection or overlap on at least one time unit (eg, one OFDM symbol). For example, in FIG. 1A, signal 1 and signal 3 overlap in reception time, and the first communication device needs to receive both signals simultaneously. Alternatively, in FIG. 1B, signal 1 and signal 3 - signal 6 overlap in reception time, and the first communication device needs to receive the five signals simultaneously. The first time instant can be characterized based on the subframe/slot/symbol where the received signal of any one of the N received signals is located. For example, in FIG. 1A, the first moment can be understood as the subframe/slot/symbol occupied by the signal 1 on the carrier 1.
