Definitions
- the present disclosure relates to the field of communication technologies, and in particular, to a signal transmission method, device, terminal, and network-side device.
- MIMO Multiple-Input Multiple-Output

- LTE-A LTE Evolution
- OFDM Orthogonal Frequency Division Multiplexing
- Rel-8 In LTE Rel-8, it can support up to 4 layers of MIMO transmission. Rel-0 focuses on enhancement of Multi-User Multiple Input Multiple Output (MU-MIMO) technology. MU-MIMO transmission in Transmission Mode (TM) -8 can support up to 4 downlink data. Floor. Rel-10 introduced support for 8 antenna ports to further improve the spatial resolution of channel state information, and further extended the single-user multiple-input multiple-output (Single-User MIMO (SU-MIMO)) transmission capability to a maximum of 9 data layers. Rel-13 and Rel-14 introduced Full Dimension-MIMO (FD-MIMO) technology support to 32 ports to achieve full-dimensional and vertical beamforming.

- TM Transmission Mode
- SU-MIMO single-user multiple-input multiple-output
- SU-MIMO single-user multiple-input multiple-output
- Rel-13 and Rel-14 introduced Full Dimension-MIMO (FD-MIMO) technology
- a large-scale antenna technology is introduced in a mobile communication system.
- a fully digital large-scale antenna can have up to 128/256/512 antenna units and up to 128/256/512 transceiver units, each antenna unit being connected to a transceiver unit.
- pilot signals of up to 128/256/512 antenna ports
- the terminal measures channel state information and feeds it back.
- an antenna array with up to 32/64 antenna units can also be configured.
- a huge beamforming gain is obtained to compensate for signal attenuation caused by path loss.
- the path loss makes the coverage of wireless signals extremely limited.
- the coverage of wireless signals can be extended to a practical range.
- each antenna unit has independent transceiver unit, which will greatly increase the size, cost and power consumption of the device.
- ADC analog-to-digital converter
- DAC digital-to-analog converter
- the power consumption has only been reduced by about 1/10 in the past ten years.
- the performance improvement is also relatively limited.
- a technical solution based on analog beamforming is proposed. As shown in FIG. 1 and FIG. 2, the transmitting end and the receiving end have N t and N r transceiver units, respectively.
- the main feature of analog beamforming is the weighted shaping of intermediate frequency (Figure 1) or radio frequency signals ( Figure 2) by phase shifters.
- the advantage is that all transmitting (receiving) antennas have only one transceiver unit, which is simple to implement and reduces cost, size and power consumption.
- FIG. 3 a digital-analog hybrid beamforming transceiver architecture solution is proposed, as shown in FIG. 3.
- the sender and receiver have with Transceiver units, number of transmitting antenna units Number of receiving antenna units
- the maximum number of parallel transport streams supported by beamforming is
- the hybrid beamforming structure in Figure 3 balances the flexibility of digital beamforming with the low complexity of analog beamforming. It has the ability to support multiple data streams and multiple users to form at the same time. At the same time, the complexity is also Controlled within a reasonable range.
- PA refers to a power amplifier
- LNA refers to a low noise amplifier
- Both the analog beamforming and the digital-analog mixed beamforming need to adjust the analog beamforming weights at the transmitting and receiving ends so that the beams formed by them can be aligned with the opposite end of the communication.
- the beamforming weights sent by the base station and the beamforming weights received by the terminal need to be adjusted, while for uplink transmissions, the beamforming weights sent by the terminal and received by the base station need to be adjusted.
- Beamforming weights are usually obtained by sending training signals. In the downlink direction, the base station sends a downlink beam training signal, and the terminal measures the downlink beam training signal, selects the best base station transmission beam, and feeds back the beam-related information to the base station. At the same time, the corresponding best receiving beam is selected and stored locally.
- a terminal equipped with multiple transmitting antennas can perform uplink beamforming.
- a terminal in an RRC (Radio Resource Control) connected state (RRC_CONNECTED) state may be semi-statically configured with multiple terminal-specific uplink sounding reference signal (SRS) resources.
- SRS signals transmitted on each SRS resource are beamformed using a specific beamforming matrix.
- the terminal sends these SRS resources in the uplink.
- Transmission and reception points (TRP) measure the signal quality of different SRS resources and select the optimal SRS resource.
- the TRP sends the index of the selected SRS resource (such as a sounding reference signal resource identifier (SRS resource indicator, SRI), that is, an SRS resource indicator) to the terminal via downlink control information (DCI).
- SRS resource indicator sounding reference signal resource identifier
- DCI downlink control information
- the terminal may have multiple antenna panels (or antenna panels) for uplink transmission, and each antenna panel consists of a group of antenna units.
- the number of antenna units and the arrangement of antenna units in each panel are implementation issues, and different terminals may have different implementations.
- the terminal can send one data layer from one panel at a time, and the terminal can also send one data layer from a subset of antenna panels (including more than one antenna panel) at the same time.
- SRS resources transmission of SRS signals.
- a single antenna panel terminal can be configured with an SRS resource set for transmitting beam scanning.
- Each SRS resource set includes multiple SRS resources, and different SRS resources use different beams for beamforming. Since one antenna panel can only form one analog beam at one time, different SRS resources (using different beams) in one SRS resource set are transmitted at different times.
- the base station gNB receives the SRS resource set, determines a preferred transmission beam (for example, a transmission beam used by the SRS resource with the optimal reception quality) based on the received SRS resource set, and instructs the terminal. Subsequently, the base station may configure a second SRS resource set for the terminal for acquiring channel state information (Channel State Information, CSI).
- CSI Channel State Information
- This SRS resource set for CSI acquisition may include multiple SRS resources, and each SRS resource uses the same or different analog beams for beamforming (the analog beams here can be obtained through the previous beam scanning process).
- the base station After receiving the SRS corresponding to the second SRS resource set and completing channel estimation, the base station schedules a physical uplink shared channel (PUSCH), and includes a PUSCH scheduling grant that points to a second SRS resource set (for CSI SRI indication of the SRS resource in the acquired SRS resource set).
- the terminal uses the analog beam transmitting the SRS indicated by the SRI as the transmission beam of the PUSCH.
- the related art does not support the base station to flexibly schedule the terminal according to the number of antenna panels of the terminal, so that the PUSCH can perform multi-antenna panel joint transmission from multiple antenna panels at the same time.
- An object of the present disclosure is to provide a signal transmission method, device, terminal, and network-side equipment, so as to solve the problem that the network-side equipment does not support multiple groups of uplink scheduling information for the terminal in the related art, thereby limiting the flexibility of uplink transmission.
