The arrows shown in fig. 1 may represent uplink/downlink transmissions over a cellular link between the terminal device 10 and the network device 20.

In the 5G study, beamforming is an important technique for improving coverage and spectral efficiency. Beamforming (BF) is an implementation of adaptive array smart antennas, and is a digital signal processing technique implemented on an antenna array composed of a plurality of array elements. The method utilizes the difference of the useful signals and the interference signals on the characteristics of spatial channels such as the arrival angle and the like, and separates the useful signals and the interference signals on the space by setting a proper weighted value for the antenna array, thereby achieving the purposes of reducing the interference between users and improving the system capacity.

In order to facilitate understanding of the embodiment of the present invention, the following briefly describes the beamforming technique by taking dual-stream beamforming in fig. 2 as an example. As shown in fig. 2, two data streams at the transmitting end are scrambled and modulated, then subjected to antenna layer mapping, and subjected to precoding processing, and enter a beam forming unit, two groups of forming coefficients are obtained by calculating two different data streams, and the two data streams are formed respectively, sent to antenna ports, and directed to different users.

In uplink transmission, the terminal device may transmit a plurality of signals using different beams, and the network device may instruct the beam with the best reception quality as a beam for subsequent uplink signal transmission. Meanwhile, the terminal device may also transmit a plurality of same signals by using the same beam, and the network device receives the plurality of signals by using different beams, thereby selecting the beam with the best reception quality as the beam for subsequently receiving the signals.

Similarly, in downlink transmission, the network device may transmit a plurality of signals using different beams, and the terminal device may indicate the beam with the best reception quality as the beam for subsequent downlink signal transmission. Meanwhile, the network device may also transmit a plurality of same signals using the same beam, and the terminal device receives the plurality of signals using different beams, thereby selecting the beam with the best reception quality as the beam used for the subsequent received signal.

Therefore, in both uplink transmission and downlink transmission, the receiving end needs to know whether the same beam or different beams are used by multiple signals transmitted by the transmitting end to determine the beam used for receiving or transmitting subsequent signals.

Fig. 3 shows a schematic block diagram of a method 100 of transmitting a signal of an embodiment of the present invention. As shown in fig. 100, the method may be performed by a terminal device, for example, a user equipment, and the method 100 includes:

s110, receiving beam indication information sent by network equipment, wherein the beam indication information is used for indicating whether beams adopted for transmitting N signals are the same or not, and N is an integer greater than 1;

s120, performing transmission of the N signals with the network device according to the beam indication information.

Specifically, the network device may pre-determine whether the beam used by the terminal device or the multiple signals transmitted by the network device is the same, and the network device may further send beam indication information to the terminal device through Radio Resource Control (RRC) signaling, and the like, and may notify the terminal device of which signals in the multiple signals transmitted by the terminal device use the same beam or which signals use different signals through the beam indication information, so that the terminal device may determine how to send or receive the multiple signals according to the beam indication information. For example, when the network device notifies the terminal device to transmit a plurality of uplink signals, two of the uplink signals may use the same beam, and then the network device may use different beams to receive the two signals, so that the network device may select which beam is the best to be used for subsequently receiving the uplink signal from the beams receiving the two signals.

Therefore, the method for transmitting signals according to the embodiment of the present invention determines whether to transmit multiple signals using the same beam for signal transmission according to the beam indication information, so that the terminal device and the network device can determine the optimal beam used by each of the transmitted or received signals, thereby improving the performance of subsequent signal detection.

It should be noted that, in the first embodiment of the present invention, description is given by taking an example that a network terminal device sends beam indication information to a terminal device to inform the terminal device whether beams used for transmitting a plurality of signals are the same or not; similarly, the terminal device may also send beam indication information to the network device to inform the network device whether the beam used for transmitting the multiple signals is the same, and specifically, the beam indication information may be carried by some dedicated signaling. The invention is not limited thereto.

Second, the N signals may be uplink signals or downlink signals. The synchronization Signal may be a Broadcast Signal such as a Physical Broadcast Channel (PBCH) and a System Information Block (SIB), or a Physical Random Access Channel (PRACH), a beam-specific Reference Signal (BRS), or a downlink Reference Signal such as a Channel State Information-Reference Signal (CSI-RS), a Demodulation Reference Signal (DMRS), or a Sounding Reference Signal (SRS).

Third, the transmission of the N signals with the network device herein refers to the transmission and reception of the signals with the network device. The terminal device may receive the N signals sent by the network device, or the terminal device may send the N signals to the network device.

Optionally, in this embodiment of the present invention, the beam indication information is used to instruct the network device to send the N signals to the terminal device by using different beams, and the transmitting the N signals with the network device according to the beam indication information includes: receiving the N signals according to the beam indication information; the method further comprises the following steps: and sending first indication information to the network equipment, wherein the first indication information is used for indicating K signals in the N signals, K is more than or equal to 1 and less than or equal to N, and K is an integer.

Those skilled in the art understand that the beamforming technology can be divided into two modes, Codebook based (Codebook based) and channel reciprocity based, according to the feedback mode of the channel information. In the former, based on codebook information fed back by a terminal, a network device determines a precoding codebook adopted for next transmission; and the latter obtains downlink channel information by utilizing channel reciprocity according to a Sounding Reference Signal (SRS) sent by an uplink, and calculates and selects a precoding matrix required by the downlink. For example, if the terminal device uses N different beams to shape N signals and sends the shaped N signals to the network device, the network device usually receives the N signals using the same beam and reports one or more beam indexes to the terminal device, or the index network device of the CSI-RS resource corresponding to the one or more beam indexes may also report one or more signal indexes to the terminal device, so as to be used for the terminal device to shape the subsequent signals. Specifically, the signal index reported by the network device may be an index of a signal with the best signal quality in downlink signals sent by the terminal device using different beams, or may be an index of a second signal quality or other beam indexes, which is not limited in the present invention.

Optionally, in this embodiment of the present invention, the beam indication information is used to instruct the terminal device to send the N signals to the network device by using different beams, and the transmitting the N signals with the network device according to the beam indication information includes: according to the beam indication information, the beam transmits the N signals; the method further comprises the following steps: and receiving second indication information sent by the network equipment, wherein the second indication information is used for indicating L signals in the N signals, L is more than or equal to 1 and less than or equal to N, and L is an integer.

For example, if the network device uses N different beams to shape N signals and sends the shaped N signals to the terminal device, the terminal device usually receives the N signals using the same beam and reports one or more beam indexes or indexes of CSI-RS resources corresponding to the one or more beam indexes to the network device, and the terminal device may also report the indexes of the one or more signals to the network device, so as to be used for the network device to shape the subsequent signals by beams. Specifically, the signal index reported by the terminal device may be an index of a signal with the best signal quality in downlink signals sent by the network device using different beams, or may be an index of a second signal quality or other beam indexes.

Further, after the terminal device transmits a plurality of signals by using different beams, the terminal device may determine a beam used for transmitting a subsequent signal according to the second indication information. Specifically, the terminal device determines, according to the received second indication information, a beam used for transmitting a signal indicated by the second indication information, and uses the determined beam as a beam used for transmitting a subsequent signal.

Optionally, in this embodiment of the present invention, the beam indication information is used to instruct the network device to send the N signals to the terminal device by using the same beam, and the transmitting the N signals with the network device according to the beam indication information includes: receiving the N signals by adopting different wave beams according to the wave beam indication information; the method further comprises the following steps: from among the beams employed for receiving the N signals, a beam employed for receiving a subsequent signal is determined.

Similarly, if the terminal device determines that the network device uses the same beam to transmit multiple signals to the terminal device according to the beam indication information, the network device may receive the multiple signals after being shaped using different beams, and determine the beam used by the signal with the best reception quality from among the multiple signals, so as to determine which beam is used to receive the signal with the best signal quality. It should be understood that the signal with the best reception quality may be one or more signals, and the present invention is not limited thereto.

Optionally, in this embodiment of the present invention, the beam indication information is used to instruct the terminal device to send the N signals to the network device by using the same beam, and the transmitting the N signals with the network device according to the beam indication information includes: and according to the beam indication information, the N signals are transmitted by adopting the same beam.

Similarly, if the terminal device determines, according to the beam indication information, that the terminal device transmits multiple signals using the same beam, the terminal device may transmit the multiple signals using the same beam, the network device may receive the multiple signals using different beams, and the network device may determine, from the multiple signals, a beam used by a signal with the best reception quality, so as to determine which beam is used to receive the signal with the best signal quality. It should be understood that the signal with the best reception quality may be one or more signals, and the present invention is not limited thereto.

It should be understood that the above-described embodiments are merely illustrative, and embodiments of the present invention should not be limited thereto. For example, if the terminal device determines that the terminal device should transmit a plurality of signals to the network device using different beams according to the beam indication information, the terminal device may transmit the plurality of signals to the network device using different beams, or the terminal device may transmit the plurality of signals to the network device using the same beam, and the terminal device may transmit or receive the plurality of signals according to its own condition using the beam indication information as one reference information.

It should also be understood that the N signals in the foregoing embodiment may include both uplink signals and downlink signals, that is, the beam indication information may indicate that uplink signals in the N signals use the same or different beams, or may indicate that downlink signals in the N signals use the same or different beams at the same time, and the embodiment of the present invention is not limited to a scenario in which the N signals only refer to uplink signals or downlink signals.

Optionally, in this embodiment of the present invention, the beam indication information is carried in at least one of the following signaling or signals: radio Resource Control (RRC) signaling, Media Access Control (MAC) signaling, Downlink Control Information (DCI) signaling, downlink synchronization signal, downlink random Access signal, and downlink pilot signal.

Specifically, the beam indication information is transmitted through RRC signaling, MAC signaling, or DCI signaling, or is carried in a downlink signal. For example, the beam indication information may be carried by a Primary Synchronization Signal (PSS) sequence, a Secondary Synchronization Signal (SSS) sequence, or a Physical Broadcast Channel (PBCH), or may be implicitly indicated by other information in DCI; the beam indication information may also be transmitted to the terminal device together with transmission resource configuration information of a plurality of signals. For example, if the transmission resource configuration information of the plurality of signals is configured through RRC signaling, the beam indication information may be transmitted in the same RRC information domain as the transmission resource configuration. The beam indication signal may also be carried by some dedicated downlink control signals.

Further, the MAC signaling carrying the beam indication information is used to activate or deactivate the N signals; and/or if the N signals are reference signals, the DCI signaling carrying the beam indication information is used to trigger the N signals, and if the N signals are channels, the DCI signaling carrying the beam indication information is used to schedule the N signals. For example, if the CSI-RS resource is activated through MAC signaling, the beam indication information may be carried through MAC signaling.

Optionally, the beam indication information may not be carried by the DCI signaling triggering or scheduling the multiple signals and/or the MAC signaling activating or deactivating the multiple signals, and the beam indication information is carried in other signaling, for example, in RRC signaling, which is not limited in this embodiment of the present invention.

It should be understood that if the beam indication information is transmitted together with transmission resource configuration information corresponding to the plurality of signals, the plurality of signals may be the same type or different types of signals with different transmission resource configurations. For example, the multiple signals are the same pilot signal or the same channel. For example, the multiple signals are all PRACH signals, or all SRS signals, or all DMRS signals, or all CSI-RS signals, or all beam-specific reference signals (BRS), or all synchronization signals, or all Physical Downlink Shared Channel (PDSCH) signals, or all Physical Uplink Shared Channel (PUSCH) signals.

Optionally, in this embodiment of the present invention, the beam indication information includes beam information in one-to-one correspondence to each of the N signals, and the beam indication information indicates whether beams adopted by the N signals are the same through at least one of: if the contents indicated by the beam information of a first signal and a second signal in the N signals are the same, transmitting the first signal and the second signal by using the same beam; if the contents indicated by the beam information of a third signal and a fourth signal in the N signals are different, transmitting the third signal and the fourth signal by using different beams; if the beam information of a fifth signal and a sixth signal in the N signals are both preconfigured first values (for example, the first value may be 0), transmitting the fifth signal and the sixth signal with the same beam; if the beam information of a seventh signal and an eighth signal in the N signals are both a preconfigured second value (for example, the second value may be 1), transmitting the seventh signal and the eighth signal using different beams, and the first value and the second value being different; if the content indicated by the beam information of a ninth signal of the N signals includes an index of a tenth signal of the N signals, transmitting the ninth signal and the tenth signal with the same beam; if the content indicated by the beam information of the eleventh signal in the N signals includes the index of the twelfth signal in the N signals, the beam used for transmitting the eleventh signal and the twelfth signal is different.

Specifically, the beam indication information may be a bit table, where each bit in the bit table corresponds to one of the signals, and each bit represents the beam information adopted by the signal, for example, 8 bits are adopted to represent 8 signals, where a signal with bit 0 may be assumed to adopt the same beam, a signal with bit 1 may adopt different beams, or a signal with bit 1 may be assumed to adopt the same beam, and a signal with bit 0 may adopt different beams. For another example, in the 8 pieces of beam information included in the beam indication information, if the content indicated in one piece of beam information includes an index of another signal, it may be assumed that the beams used by the two signals are the same, or it may be assumed that the beams used by the two signals are different. It should be understood that the above description is intended to be illustrative only, and not limiting.

Fig. 4 shows a schematic block diagram of a method 200 of transmitting a signal of an embodiment of the invention. The method 200 may be performed by a network device, for example, a base station, as shown in fig. 4, and the method 200 includes:

s210, sending beam indicating information to the terminal equipment, wherein the beam indicating information is used for indicating whether beams adopted for transmitting N signals are the same or not, and N is an integer greater than 1;

It should be understood that the method for transmitting signals based on the network device side, the interaction with the terminal device, the related characteristics, the functions, and the like correspond to the related characteristics and the functions of the terminal device side, and for brevity, no further description is provided here.

The technical scheme of the present application will be described in detail with reference to examples 1 to 5.

Example 1: the network side configures N CSI-RS resources, and configures 3-bit beam indication information for each CSI-RS resource, wherein the beam indication information and the resource configuration information of each CSI-RS resource are indicated together. And the terminal determines whether the CSI-RS corresponding to different CSI-RS resources adopt the same wave beam or not according to the wave beam indication information of each CSI-RS resource. Specifically, the CSI-RSs corresponding to the CSI-RS resources with the same indication information use the same beam, and the CSI-RSs corresponding to the CSI-RS resources with different indication information use different beams. For example, if N is 4, and the CSI-RS resource 0 and the CSI-RS resource 2 correspond to the beam indication information 0, the CSI-RS resource 1 corresponds to the beam indication information 1, and the CSI-RS resource 3 corresponds to the beam indication information 2, it indicates that the CSI-RS transmissions corresponding to the resource 0 and the resource 2 use the same beam (denoted as beam 1), the CSI-RS transmission corresponding to the resource 1 uses another different beam (denoted as beam 2), and the CSI-RS transmission corresponding to the resource 3 uses a different beam (denoted as beam 3). The CSI-RS transmitted by the same beam can be used for downlink receiving beam determination, and the CSI-RS transmitted by different beams can be used for downlink transmitting beam determination.

Example 2: the network side configures N SRS resources, and configures 1-bit beam indication information for each SRS resource, and the beam indication information and the resource configuration information of each SRS resource indicate together. And the terminal determines whether different SRS adopt the same wave beam or not according to the wave beam indication information of each SRS resource. Specifically, the SRS corresponding to the SRS resource whose indication information is 0 uses the same beam, and the SRS corresponding to the SRS resource whose indication information is 1 uses different beams. For example, if N is 8, and all the beam indication information corresponding to SRS resources {0,1,2,3} indicate 0, and all the beam indication information corresponding to SRS resources {4,5,6,7} indicate 1, the same beam (denoted as beam 1) is used for SRS transmission corresponding to SRS resources {0,1,2,3} and different beams (denoted as beams 2,3,4,5) are used for SRS transmission corresponding to SRS resources {4,5,6,7 }. The SRS transmitted by the same beam may be used for uplink reception beam determination, and the SRS transmitted by different beams may be used for uplink transmission beam determination. The same approach may also be applied to PRACH transmission.

Example 3: the network side configures N CSI-RS resources in advance through RRC signaling, and triggers the terminal to perform aperiodic CSI-RS measurement based on K CSI-RS resources through downlink DCI, wherein K is an integer less than or equal to N. The DCI carries 1-bit beam indication information, and if the indication information indicates 0, the triggered CSI-RS corresponding to the K CSI-RS resources adopt the same beam; and if the indication information indicates 1, indicating that the triggered CSI-RS corresponding to the K CSI-RS resources adopt different beams. The CSI-RS transmitted by the same beam can be used for downlink receiving beam determination, and the CSI-RS transmitted by different beams can be used for downlink transmitting beam determination.

Example 4: and the network side triggers the terminal to perform non-periodic SRS transmission through the downlink DCI, and the terminal needs to repeatedly send N SRSs each time. The N SRS may use the same frequency domain resource/sequence, or may use different frequency domain resources/sequences. The DCI carries 1-bit beam indication information, and if the indication information indicates 0, the triggered N SRS transmissions adopt the same beam; if the indication information indicates 1, it indicates that the triggered N SRS employs different beams. The SRS transmitted by the same beam may be used for uplink reception beam determination, and the CSI-RS transmitted by different beams may be used for uplink transmission beam determination.

Example 5: in downlink synchronization signal transmission, the beam indication information may be carried by a PSS sequence, an SSS sequence, or a PBCH, where PSS is taken as an example. Different PSS sequences may be used to implicitly indicate the beam indication information, that is, different information corresponds to different PSS sequences, for example, information 0 corresponds to PSS sequence 1, and information 1 corresponds to PSS sequence 2. The corresponding relation can be defined in advance, the terminal obtains the information of each PSS sequence by blindly detecting the PSS sequence, and then determines whether the PSS sequences adopt the same beam or not according to the information. Specifically, two methods can be used to determine: the information 0 indicates that the corresponding PSS sequences are transmitted by the same beam, and the information 1 indicates that the corresponding PSS sequences are transmitted by different beams; and adopting N different PSS sequences to correspond to N different beam indication information, wherein the PSS sequences with the same beam indication information adopt the same beam, and the PSS sequences with different beam indication information adopt different beams. For example, the beam indication information is K, which means that the PSS sequence is transmitted using the kth beam.
