[0022] The following describes various exemplary embodiments of the present solution with reference to the accompanying drawings, so that those of ordinary skill in the art can make and use the present solution. It will be apparent to those of ordinary skill in the art that after reading this disclosure, various changes or modifications can be made to the examples described herein without departing from the scope of the present solution. Therefore, the present solution is not limited to the exemplary embodiments and applications described and illustrated herein. In addition, the specific order or hierarchy of the blocks in the methods disclosed herein is merely an example method. Based on design preferences, the specific order or hierarchy of the blocks of the disclosed method or process can be rearranged while remaining within the scope of the present solution. Therefore, those of ordinary skill in the art will understand that the methods and techniques disclosed herein present various blocks or actions in an example order, and the present solution is not limited to the specific order or hierarchy presented unless otherwise expressly stated.

[0023] The development of 5G wireless communication systems aims to achieve higher data communication rates (e.g., in Gbps), a large number of communication links (e.g., 1M / Km 2 ), ultra-low latency (e.g., below 1 ms), higher reliability, and higher energy efficiency (e.g., at least 100 times more efficient than previous systems). To achieve such improvements, in a wireless communication system under the 5G standard, two uplink transmission modes have been developed to enable a user equipment (UE) to transmit an uplink (UL) signal (e.g., PUSCH, PUCCH, SRS, and PRACH) at full power under a maximum output power threshold. Although existing 5G New Radio (NR) technologies allow a UE to support non-codebook-based uplink transmissions using full power, there is no complete solution to support a terminal to perform uplink transmissions using full transmission power for codebook-based uplink transmissions.

[0024] To solve this problem, two corresponding uplink transmission modes have been developed to match this functionality. These two uplink transmission modes are referred to as full power mode 1 and mode 2. Mode 1 corresponds to the precoding matrix (TPMI) used by a UE with extended low coherence antenna port capabilities, while mode 2 corresponds to enhanced UE antenna port virtualization capabilities and full power TPMI group reporting. For mode 2, methods of antenna port virtualization and TPMI group reporting are used to support full power transmission of a UE. The purpose of TPMI group reporting is to support the use of as many different power amplifier (PA) architectures as possible to implement full power transmission with limited signaling overhead. Therefore, the present disclosure is directed to systems and methods for designing a TPMI group to optimize the TPMI group reporting function in mode 2.

[0025] The coherence capability of antenna ports refers to whether the relative phases between ports can be adjusted. In the case of full coherence, the UE can control the relative phases between all antenna ports to be used for transmission. In the case of partial coherence, the UE can control the relative phases within port pairs (e.g., paired coherence relationships), but cannot guarantee the relative phases between port pairs (e.g., coherence relationships). In the case of incoherence, the UE cannot guarantee the coherence between any pair of device antenna ports.

[0026] As used herein, the term "codeword" refers to a precoding matrix or transmission precoding matrix index (TPMI) for multi-port transmission based on a codebook used by a terminal. Herein, each row of the precoding matrix represents an antenna port, and each column represents a transmission layer. In addition, the "first communication node" may be referred to as a terminal and may include or be implemented as a UE, user terminal, mobile station (MS), station (STA), etc., while the "second communication node" may be referred to as the network side and may include or be implemented as a base station, next-generation node B (gNB), E-UTRAN node B (eNB), core network, transmit / receive point (TRP), access point (AP), etc.

[0027] Generally, the base station can determine the number of antenna ports based on the capabilities of the transmitting antennas of the first communication node (e.g., UE) and can configure the UE to transmit one or more sounding reference signals (SRS). The SRS is used to measure the uplink channel, which is also referred to as a channel sounding signal. After obtaining the results of channel sounding, the base station accordingly determines the multiple-input multiple-output (MIMO) parameters (e.g., number of layers, precoding, etc.) for one or more subsequent uplink transmissions and indicates the number of layers and the corresponding precoding matrix (e.g., TPMI) to the UE. Then, the UE performs precoding on the data using the precoding matrix indicated by the base station and transmits the data to the base station.

[0028] In the NR system, uplink transmissions using MIMO can be classified into codebook-based uplink transmissions and non-codebook-based uplink transmissions. Note that a codebook is a set of information of predefined codewords and corresponding layers and includes at least one codeword.

[0029] For codebook-based transmissions, the base station selects appropriate precoding information (e.g., codeword) in a predefined codebook based on the measured channel and indicates the selected precoding information to the UE by indicating the TPMI corresponding to the selected precoding information.

[0030] Figure 1Illustrated is an example UE 101 that performs an uplink transmission with a base station 102, which is shown by a network link or connection 110. In some examples, the network link or connection 110 can be used for uplink communication and downlink communication between the UE 101 and the base station 102. In this example, the UE 101 is a first communication node. In other examples, the UE 101 can be a wireless communication device, a user terminal, an MS, an STA, or any other terminal. In this example, the base station 102 is a second communication node. In other examples, the base station 102 can be a gNB, an eNB, a core network, a TRP, an AP, or any other network-side component.

[0031] Figure 2A is a schematic diagram illustrating a method 200a for wireless communication according to some embodiments. The method 200a is performed by a first communication node or terminal, which can include or be implemented as a UE, a user terminal, an MS, an STA, etc., corresponding to the Figure 1 UE 101 in. At 210, the first communication node reports at least one codeword to a second communication node or network according to the transmission mode of the first communication node. At 220, the first communication node receives at least one indicated codeword from the second communication node that can be used for at least one subsequent uplink transmission. Then, at 230, the first communication node performs at least one subsequent uplink transmission.

[0032] In one embodiment, the transmission mode of the first communication node is at least one of a first transmission mode (e.g., mode 1 or full-power mode 1), a second transmission mode (e.g., mode 2 or full-power mode 2), a full-power transmission mode (e.g., mode 0 or full-power), or a transmission mode that supports indicating whether the indicated codeword corresponds to a full-power state.

[0033] In one embodiment, at least one codeword can be reported in the form of at least one precoding matrix group corresponding to at least one TPMI group according to the transmission mode. Thus, the first communication node can report at least one corresponding TPMI group to the second communication node to help the second communication node configure or indicate the codewords that can be used for subsequent codebook-based uplink transmissions.

[0034] The first communication node reports the number of antenna ports, the coherence capability of the antenna ports, and the full-power transmission mode for uplink transmission to the second communication node. In some embodiments, the first communication node uses this information to determine at least one codeword to be reported, which can be a precoding matrix group or a TPMI group. In some of these embodiments, the indication information field of at least one codeword reported by the first communication node is a code point or a bitmap.

[0035] In an example embodiment, when the number of antenna ports reported for the uplink transmission of the first communication node is 4, the reported coherence capability of the antenna ports is non - coherent, and the full - power transmission mode includes mode 2, at least one codeword reported by the first communication node is one of a precoding matrix group and / or a TPMI group G0 - G11, as Figure 3A and Figure 3B shown. Figure 3A is the first part of a table according to some embodiments of the present disclosure, which shows the full - power TPMI groups for 4 - port, non - coherent UEs in mode 2. Figure 3B is the second part of a table according to some embodiments of the present disclosure, which shows the full - power TPMI groups for 4 - port, non - coherent UEs in mode 2.

[0037] In an example embodiment, when the number of antenna ports reported for the UL transmission of the first communication node is 4, the reported coherence capability of the antenna ports is partially coherent, and the full - power transmission mode includes mode 2, at least one codeword reported by the first communication node is one of a precoding matrix group and / or a TPMI group G0 - G11, as Figure 4A and Figure 4B shown. Figure 4A is the first part of a table according to some embodiments of the present disclosure, which shows the full - power TPMI groups for 4 - port, partially coherent UEs in mode 2. Figure 4B is the second part of a table according to some embodiments of the present disclosure, which shows the full - power TPMI groups for 4 - port, partially coherent UEs in mode 2.

[0038] In another embodiment, when the number of antenna ports reported for the uplink transmission of the first communication node is 4, the reported coherence capability of the antenna ports is partially coherent, and the full - power transmission mode includes mode 2, at least one codeword reported by the first communication node may include at least one of a precoding matrix group and / or a TPMI group G0 - G5 as Figure 4A shown.

Figure 9B shows a block diagram of an example UE 901 according to some embodiments of the present disclosure. Refer to Figure 1 - 9B , the UE 901 (e.g., a wireless communication device, a terminal, a mobile device, a mobile user, etc.) is an example implementation of the UE described herein, and the base station 902 is an example implementation of one or more base stations described herein.

[0059] The base station 902 and the UE 901 may include components and elements configured to support known or conventional operating features that are not described in detail herein. In an illustrative embodiment, as described above, the base station 902 and the UE 901 can be used to communicate (e.g., transmit and receive) data symbols in a wireless communication environment. For example, the base station 902 can be a base station (e.g., gNB, eNB, etc.), a server, a node, or any suitable computing device for implementing various network functions.

To clearly illustrate this interchangeability of hardware, firmware, and software, the various illustrative components, blocks, modules, circuits, and blocks have been generally described above in terms of their functionality. Whether such functionality is implemented as hardware, firmware, or software, or as a combination of these technologies, depends on the particular application and the design constraints imposed on the overall system. Those skilled in the art can implement the described functionality in various ways for each particular application, but such implementation decisions do not result in a departure from the scope of the present disclosure.

[0072] In addition, those of ordinary skill in the art will understand that the various illustrative logical blocks, modules, devices, components, and circuits described herein can be implemented within or performed by an integrated circuit (IC), which can include a general-purpose processor, a digital signal processor (DSP), an application-specific integrated circuit (ASIC), a field-programmable gate array (FPGA), or other programmable logic device, or any combination thereof. The logical blocks, modules, and circuits can also include antennas and / or transceivers to communicate with various components within a network or within a device. The general-purpose processor can be a microprocessor, but optionally, the processor can be any conventional processor, controller, or state machine. The processor can also be implemented as a combination of computing devices, such as a combination of a DSP and a microprocessor, multiple microprocessors, one or more microprocessors in conjunction with a DSP core, or any other suitable configuration that performs the functions described herein.

[0073] If implemented in software, the functionality can be stored as one or more instructions or code on a computer-readable medium. Thus, the blocks of the methods or algorithms disclosed herein can be implemented as software stored on a computer-readable medium.

[0074] In the present application, the term "module" as used herein refers to software, firmware, hardware, and any combination of these components for performing the relevant functions described herein. Additionally, for the purposes of discussion, various modules are described as discrete modules; however, it will be apparent to those of ordinary skill in the art that two or more modules may be combined to form a single module that performs the relevant functions in accordance with an embodiment of the present solution.

[0075] Furthermore, in an embodiment of the present solution, a memory or other memory, as well as communication components, may be employed. It should be understood that, for clarity, the above description has described embodiments of the present solution with reference to different functional units and processors. However, it is apparent that any suitable functional distribution between different functional units, processing logic elements, or domains may be used without departing from the present solution. For example, functions illustrated as being performed by separate processing logic elements or controllers may be performed by the same processing logic element or controller. Thus, the reference to a particular functional unit is merely a reference to a suitable means for providing the recited function, and does not indicate a strict logical or physical structure or organization.

[0076] Various modifications to the described embodiments of the present disclosure will be apparent to those skilled in the art, and the general principles defined herein may be applied to other embodiments without departing from the scope of the present disclosure. Thus, the present disclosure is not limited to the embodiments shown herein, but rather to the broadest scope consistent with the novel features and principles disclosed herein, as set forth in the following claims.
