The signal type for identifying the uplink signal may be a signal type for identifying an uplink signal transmitted in an uplink channel, for example: a signal type of an uplink signal that needs to be transmitted in an uplink channel is identified.
After identifying the signal type of the uplink signal, the uplink transmission beam corresponding to the signal type may be determined, so that the uplink signal may be transmitted in an uplink channel using the uplink transmission beam.
The determining, by the terminal, the uplink transmission beam corresponding to the uplink channel carrying the signal of the signal type may be determining a beamforming factor (beamforming beam) corresponding to the uplink channel, and then beamforming the beam, so as to transmit the uplink signal using the uplink transmission beam in the uplink channel. The beamforming in the uplink channel may be analog beamforming or may also be digital beamforming, which is not limited in this embodiment of the present invention.

And the uplink sending beam is determined according to the downlink receiving beam of the source signal of the QCL associated with the uplink channel.
In addition, the source signal of QCL is associated with the uplink channel including, but not limited to, the following ways:
and associating the source signal of the QCL with the DMRS port of the uplink channel, wherein the uplink transmission beam of the uplink channel is the uplink transmission beam of the DMRS port corresponding to the uplink channel. For example, one or a group of DMRS ports corresponds to a source signal of one QCL, and an uplink beam corresponding to the DMRS port corresponding to the source signal of the QCL can be obtained according to the source signal of the QCL, so that the uplink channel uses an uplink transmission beam identical to the DMRS port corresponding to the uplink channel. For example, the uplink transmission beam of the DMRS port corresponding to the uplink transmission beam may be derived from the downlink transmission beam or the downlink reception beam of the source signal of the QCL, and the uplink channel uses the same uplink transmission beam as the DMRS port corresponding to the uplink transmission beam. For example, an uplink transmission beam of the corresponding DMRS port can be derived through an uplink transmission beam of the source signal of the QCL, and the uplink channel uses the same uplink transmission beam as the corresponding DMRS port; or
And associating the source signal of the QCL with an uplink channel port of the uplink channel, wherein the uplink sending beam of the uplink channel is the uplink sending beam of the uplink channel port corresponding to the uplink channel. One upstream channel port has a QCL source signal associated with it. For example, the uplink transmission beam of the uplink channel port corresponding to the uplink transmission beam can be derived through the downlink transmission beam or the downlink reception beam of the source signal of the QCL, and then, the uplink transmission beam of the uplink channel port corresponding to the uplink transmission beam can be derived through the uplink transmission beam of the source signal of the QCL; or
And associating the source signal of the QCL with the sequence of the uplink channel, wherein the uplink sending beam of the uplink channel is the uplink sending beam of the sequence transmitted in the uplink channel. For example, one or more uplink transmission sequences correspond to a source signal of a QCL, an uplink beam corresponding to the uplink transmission sequence corresponding to the source signal of the QCL may be derived according to the source signal of the QCL, for example, an uplink transmission beam of the uplink transmission sequence corresponding to the source signal of the QCL may be derived through a downlink transmission beam or a downlink reception beam of the source signal of the QCL, and for example, an uplink transmission beam of the uplink transmission sequence corresponding to the source signal of the QCL may be derived through an uplink transmission beam of the source signal of the QCL.
The source signal of the QCL may be an uplink signal or a downlink signal, for example: the reference signal can be DMRS, SRS, SS block, PBCH block, CSI-RS, PDSCH and the like. The uplink channel may be a PUSCH channel or a PUCCH channel, and the PUCCH may be a short PUCCH or a long PUCCH.
It should be noted that the QCL in the embodiment of the present invention may be QCL-ed, or the QCL may be spatial QCL.
Optionally, if the signal type of the uplink signal includes an aperiodic, the uplink transmission beam includes:
an uplink transmission beam determined according to the source signal of the QCL associated with the uplink signal; or,
an uplink transmission beam determined according to the source signal of the QCL associated with the uplink channel; or,
implicitly indicated uplink transmit beams; or,
and the semi-statically configured uplink transmission beam.
The uplink transmission beam determined according to the source signal of the QCL associated with the uplink signal and the uplink transmission beam determined according to the source signal of the QCL associated with the uplink channel may refer to the corresponding descriptions above, which are not described herein again and may achieve the same beneficial effects.
The implicitly indicated uplink transmission beam may be implicitly indicated by some messages or some beams, so that transmission overhead may be saved. For example: the terminal uses the same beam as a downlink reception beam of the PDCCH as an uplink transmission beam of the PUCCH.
The semi-statically configured uplink transmission beam may be configured by the network side device semi-statically for the terminal, and for example, the uplink transmission beam is configured only when the uplink signal is triggered. For example: and configuring the uplink transmission beam for the terminal through the semi-static configuration message. Of course, the uplink transmission beam may also be obtained by one associated source signal, and refer to the embodiment of the periodic uplink signal specifically, which is not limited herein.
Optionally, the source signal is a source signal that is indicated by the network side device for the terminal device through a high-level signaling.
In this embodiment, the network side device can implement the source signal indicated by the high-level signaling for the terminal device, thereby improving the flexibility of configuring the uplink transmission beam.
Optionally, the source signal is a source signal explicitly indicated by a dynamic physical layer signal.
The physical layer signal may be referred to as an L1 signal, for example: the uplink signal or source signal of the spatial QCL-ed associated with the uplink channel (e.g., PUCCH) may be explicitly indicated in the dynamic L1 signal triggering the PUCCH.
In this embodiment, the source signal explicitly indicated by the dynamic physical layer signal can improve the flexibility of the system.
Optionally, the source signal is indicated by a DL grant triggering downlink channel transmission; or
The source signal is indicated by triggering a DL grant or a UL grant of the uplink signal.
For example: the uplink signal is HARQ-ACK, so that the source signal of QCL-ed associated with the HARQ-ACK can be indicated in the DL grant triggering PDSCH transmission. Another example is: the uplink signal is A-CSI (aperiodic CSI), and a source RS of QCL-ed associated with the uplink signal can be indicated in a DL grant or a UL grant triggering the A-CSI. Due to the DL grant or the UL grant, additional signaling can be avoided, so as to save transmission resources.
Optionally, the uplink transmission beam determined according to the source signal of the QCL associated with the uplink signal includes:
and the uplink transmission beam is determined according to the downlink beam explicitly indicated by the PDSCH corresponding to the uplink signal.
The PDSCH corresponding to the uplink signal may be understood that the source signal of the QCL associated with the uplink signal is a PDSCH signal, and thus, the uplink transmission beam determined by the downlink beam explicitly indicated by the PDSCH, for example: the uplink transmission beam of HARQ-ACK bits transmitted on the PUCCH can be inferred from the downlink beam indication of the explicit indication of the corresponding PDSCH. Specifically, the user terminal finds the downlink transmission beam of the PDSCH, deduces the downlink reception beam of the PDSCH, and deduces the uplink transmission beam of the HARQ-ACK transmitted on the PUCCH using the downlink reception beam. This can avoid adding extra signaling to save transmission resources. It should be noted that, here, HARQ-ACK is only used as an example, in this embodiment, the uplink signal may also be other signals such as CSI or SR, and this embodiment of the present invention is not limited thereto.
The uplink transmission beam determined according to the downlink beam explicitly indicated by the PDSCH corresponding to the uplink signal may further include the following manner: and explicitly indicating the QCL source signal corresponding to the PDSCH corresponding to the uplink signal. So that the terminal can derive the uplink transmission beam corresponding to the uplink signal based on the QCL source signal. For example: and transmitting the HARQ-ACK bit on the PUCCH, and the terminal can deduce a downlink transmission beam of the PDSCH according to the downlink transmission beam of the QCL source signal (for example, the downlink transmission beam of the QCL source signal is the downlink transmission beam of the PDSCH). By using the downlink transmission beam of the PDSCH, the terminal can deduce the downlink receiving beam of the PDSCH, and the terminal can deduce the uplink transmission beam corresponding to the HARQ-ACK transmitted in the PUCCH by using the downlink receiving beam. It should be noted that, here, HARQ-ACK is only used as an example, in this embodiment, the uplink signal may also be other signals such as CSI or SR, and this embodiment of the present invention is not limited thereto.
Of course, the PDSCH may be other Downlink channels, such as a Physical Downlink Control Channel (PDCCH), and the embodiment of the present invention is not limited thereto.
Of course, the uplink transmission beam determined according to the source signal of the QCL associated with the uplink channel may also include: and determining an uplink transmission beam according to the downlink beam explicitly indicated by the Physical Downlink Shared Channel (PDSCH) corresponding to the uplink signal. And the same beneficial effects can be achieved.
Optionally, the determining, according to the downlink beam explicitly indicated by the PDSCH corresponding to the uplink signal, an uplink transmission beam includes:
and if the uplink signal comprises a plurality of signals, determining an uplink transmission beam according to a downlink beam explicitly indicated by the PDSCH corresponding to one or more signals.
In this embodiment, it may be implemented to transmit an uplink transmission beam determined according to a downlink beam explicitly indicated by a PDSCH corresponding to one or more signals in a plurality of uplink signals. For example: when one PUCCH can transmit multiple HARQ-ACK bits, an uplink transmission beam of the PUCCH can be inferred by a predefined uplink transmission beam of one or more HARQ-ACK bits. For example, if HARQ-ACK bits corresponding to PDSCHs of two carrier (CC) transmissions are transmitted on a PUCCH, the terminal may be preconfigured or predefined as an uplink transmission beam that determines HARQ-ACK bits of two PDSCHs of two CCs using a PDSCH of one of the CCs. It should be noted that, here, HARQ-ACK is only used as an example, in this embodiment, the uplink signal may also be other signals such as CSI or SR, and this embodiment of the present invention is not limited thereto.
It should be noted that, in the embodiment of the present invention, different uplink signals may use different transmission processes, that is, different uplink signals may use different manners to determine corresponding uplink transmission beams, for example: HARQ-ACK, A-CSI or SR use the different transmission processes above; and the transmission of different uplink signals may be independent of each other, for example: if the transmission of HARQ-ACK, A-CSI or SR on PUSCH is independent from each other. And different QCL reference signals may be used for different uplink signals, for example: the HARQ-ACK, a-CSI, or SR may use reference signals of different spatial QCLs.
Optionally, if the uplink signal includes a combination of a plurality of different signals;
the uplink transmission beam determined according to the source signal of the QCL associated with the uplink signal includes:
an uplink transmission beam determined according to a source signal of a QCL associated with one of the plurality of different signals;
the uplink transmission beam determined according to the source signal of the QCL associated with the uplink channel; the method comprises the following steps:
and the uplink transmission beam is determined according to the source signal of the QCL associated with the uplink channel corresponding to one signal in the plurality of different signals.
In this embodiment, when multiple uplink signals are jointly transmitted, an uplink transmission beam determined by a source signal of a QCL associated with one of the signals or a source signal of a QCL associated with an uplink channel corresponding to one of the signals may be used, so as to save terminal overhead. For example: HARQ-ACK and a-CSI are jointly transmitted in PUCCH, the spatial QCL hypothesis for one of the signals may be covered by the spatial QCL hypothesis for the other signal. It may further be that the spatial QCL hypothesis for HARQ-ACK covers the spatial QCL hypothesis for a-CSI; or the spatial QCL hypothesis for a-CSI covers the spatial QCL hypothesis for HARQ-ACK.
In addition, the embodiment may be applied to non-periodic, or to periodic or non-continuous signal types.
Optionally, the uplink signal includes a periodic signal whose signal type is periodic and an aperiodic signal whose signal type is aperiodic, or includes a semi-persistent signal whose signal type is semi-persistent and an aperiodic signal whose signal type is aperiodic;
the uplink transmission beam includes:
and the uplink signal comprises an uplink transmission beam corresponding to a signal.
In this embodiment, it can be realized that, if the uplink signal transmitted by the uplink signal includes signals of multiple signal types, the uplink transmission beam can be determined based on the signal type of one of the signals, so that the technical scheme can be simplified, and the power consumption of the user terminal can be saved. For determining the uplink transmission beam by using the signal type of one signal, reference may be made to the foregoing description, which is not described in detail. For example: the user terminal derives an uplink transmission beam (UE-dependent UL Tx beam from one of the signals transmitted on PUCCH) from one signal transmitted on PUCCH.
Optionally, the uplink transmission beam corresponding to the signal includes:
and the uplink transmission beam corresponding to the signal with the highest priority in the signals included in the uplink signals.
Therefore, the uplink transmission beam can be determined by selecting the signal with the highest priority according to the priority, so that the transmission performance is improved. For example: in one embodiment, the aperiodic signals have higher priority than the periodic signals, and the ue may use the uplink transmission beam corresponding to the aperiodic signals as the uplink transmission beam of the PUCCH. Or in another embodiment, the periodic signal has higher priority than the aperiodic signal, and the user terminal uses the uplink transmission beam corresponding to the periodic signal as the uplink transmission beam of the PUCCH.
It should be noted that various optional implementations described in the embodiments of the present invention may be implemented independently or in combination with each other, and the embodiments of the present invention are not limited in this respect.

The corresponding uplink sending beam can be selected according to the signal type of the uplink signal, so that the beam forming can be applied in uplink transmission, and the uplink transmission performance can be improved.
