[0174] FIG1A is a schematic diagram showing the architecture of a communication system according to an embodiment of the present disclosure.

[0175] As shown in FIG1A , a communication system 100 includes a terminal 101 and a network device 102 .

[0176] In some embodiments, the terminal 101 includes, for example, a mobile phone, a wearable device, an Internet of Things device, a car with communication function, a smart car, a tablet computer, a computer with wireless transceiver function, a virtual reality (VR) terminal device, an augmented reality (AR) terminal device, a wireless terminal device in industrial control, a wireless terminal device in self-driving, a wireless terminal device in remote medical surgery, a wireless terminal device in a smart grid, a wireless terminal device in transportation safety, a wireless terminal device in a smart city, and at least one of a wireless terminal device in a smart home, but is not limited thereto.

In this case, the interfaces between or within the access network devices involved in the embodiments of the present disclosure can be transformed into internal interfaces of the Open RAN, and the processes and information interactions between these internal interfaces can be implemented through software or programs.

[0179] In some embodiments, the network device can be composed of a centralized unit (CU) and a distributed unit (DU), where the CU can also be called a control unit. The CU-DU structure can be used to split the protocol layer of the access network device, with the functions of some protocol layers centrally controlled by the CU, and the functions of the remaining part or all of the protocol layers distributed in the DU, which is centrally controlled by the CU, but is not limited to this.

[0180] It can be understood that the communication system described in the embodiment of the present disclosure is for the purpose of more clearly illustrating the technical solution of the embodiment of the present disclosure, and does not constitute a limitation on the technical solution proposed in the embodiment of the present disclosure. Ordinary technicians in this field can know that with the evolution of the system architecture and the emergence of new business scenarios, the technical solution proposed in the embodiment of the present disclosure is also applicable to similar technical problems.

[0181] The following embodiments of the present disclosure may be applied to the communication system 100 shown in FIG1A , or a portion thereof, but are not limited thereto. The entities shown in FIG1A are illustrative only. The communication system may include all or part of the entities shown in FIG1A , or may include other entities other than those shown in FIG1A . The number and form of the entities may be arbitrary, and the entities may be physical or virtual. The connection relationships between the entities are illustrative only. The entities may be connected or disconnected, and the connection may be in any manner, including direct or indirect, wired or wireless.

[0182] The embodiments of the present disclosure can be applied to Long Term Evolution (LTE), LTE-Advanced (LTE-A), LTE-Beyond (LTE-B), SUPER 3G, IMT-Advanced, 4th generation mobile communication system (4G), 5th generation mobile communication system (5G), 5G new radio (NR), future radio access (FRA), new radio access technology (RAT), new radio (NR), new radio access (NX), future generation radio access (FX), Global System for Mobile communications (GSM (registered trademark)), CDMA2000, Ultra Mobile Broadband (UMB), IEEE 802.11 (Wi-Fi (registered trademark)), IEEE 802.16 (WiMAX (registered trademark)), IEEE 802.20, Ultra-WideBand (UWB), Bluetooth (registered trademark), Public Land Mobile Network (PLMN) networks, Device-to-Device (D2D) systems, Machine-to-Machine (M2M) systems, Internet of Things (IoT) systems, Vehicle-to-Everything (V2X), systems utilizing other communication methods, and next-generation systems based on and extending these methods. Furthermore, multiple systems may be combined (for example, a combination of LTE or LTE-A with 5G).

[0183] To improve cell-edge coverage and provide more balanced service quality within the service area, Coordinated Multiple Point transmission (CoMP) technology remains an important technology in New Radio (NR) systems. For example, it can leverage collaboration between multiple Transmission and Reception Points (TRPs) or panels to transmit / receive from multiple beams at multiple angles.

[0184] In the related art, for the Physical Uplink Shared Channel (PUSCH) / Physical Uplink Control Channel (PUCCH), transmission enhancement based on a multi-panel terminal and / or multiple TRPs is considered.

[0185] In some embodiments, uplink PUSCH transmission can be transmitted in the direction of TRPs of multiple base stations. For example, in collaborative transmission under the time division multiplexing (TDM) transmission mode, different repetitions of the same information on the PUSCH can be sent to different TRPs of the base station at different transmission occasions (TO) in the time domain. This method has relatively low requirements on the terminal capabilities, does not require the ability to support simultaneous transmission beams, and has a large transmission delay.

[0186] For the uplink, the spatial characteristics of the channels actually passed through by PUSCH channels for different TRPs may be very different. Therefore, it is considered that the D type quasi co-location (QCL Type D / QCL-D, where QCL, Quasi Co-Location, quasi co-location) of PUSCH channels in different sending directions is different.

[0187] In some embodiments, simultaneous collaborative transmission is achieved through multiple terminal panels (panels) to the TRP directions of multiple base stations to increase the reliability and throughput of transmission, and can effectively reduce the transmission delay under multiple TRPs, but requires the terminal to have the ability to send multiple beams simultaneously. Optionally, the transmission of PUSCH can be based on a single physical downlink control channel (Physical Downlink Control Channel, PDCCH), that is, a single downlink control information (single DCI, S-DCI, where DCI, Downlink Control Information, downlink control information) scheduled multi-panel / TRP transmission, as shown in Figure 1B. Optionally, the transmission of PUSCH can also be based on different PDCCHs, that is, multiple DCI (multiple DCI, M-DCI) scheduled multi-panel / TRP transmission, as shown in Figure 1C.

[0188] In some embodiments, the transmission of PUSCH can be based on uplink non-simultaneous (TDM) transmission scheduled by S-DCI, as shown in Figure 1D; the transmission of PUSCH can also be based on uplink multi-panel single TRP simultaneous transmission, as shown in Figure 1E.

[0189] In some embodiments, a terminal is generally configured with multiple physical panels. Different panels may have different capabilities, for example, they may have different numbers of Sounding Reference Signal (SRS) ports and may not necessarily support the same maximum number of data transmission layers. For example, one panel may support a maximum of 2 layers of transmission, while another panel may support a maximum of 4 layers of transmission. The network scheduler will determine whether the terminal is currently suitable for simultaneous uplink transmission of multiple panels. If the terminal is currently suitable for simultaneous uplink transmission of multiple panels and is scheduled at the same time, the network will directly or indirectly indicate relevant transmission parameters, including terminal-specific beam indication information, the number of data layers used for transmission, the allocation of demodulation reference signal (DMRS) ports used, and precoding indication information.

[0190] In some embodiments, to support uplink panel selection, an enhanced beam reporting scheme is supported, that is, the terminal is informed of the function of the panel selected for uplink transmission by updating the UL TCI state. Optionally, a terminal capability value set (UE capability value set) that can be used for uplink transmission is defined for a multi-panel terminal, and the terminal reports the set. The elements in the set include the maximum number of SRS ports supported by each panel of the terminal. Here, it is assumed that the maximum number of SRS ports corresponds to the maximum supported uplink transmission rank. Assuming that the terminal has 4 panels, and the corresponding maximum number of SRS ports is 1, 2, 2, and 4 respectively, then the maximum number of ports corresponding to the heterogeneous panels is reported, and the terminal capability set is reported as {1, 2, 4}.

This uplink beam is not guaranteed to be transmitted simultaneously.
