[0044] In the above embodiments, the terminal can use the first information to enable the network device to accurately know the terminal's support for the 6MIMO layer, thereby enabling the network device to process downlink data based on the terminal's capabilities, ensuring the reliability of downlink transmission.

[0045] In conjunction with some embodiments of the first aspect, in some embodiments, the terminal determines whether to send or not send the first information based on whether it supports downlink reception of a 6-input multiple output MIMO layer, including:

[0116] In some embodiments, the technical solutions of this disclosure can be applied to the Open RAN architecture. In this case, the interfaces between or within access network devices involved in the embodiments of this disclosure can be transformed into internal interfaces of Open RAN. The processes and information interactions between these internal interfaces can be implemented by software or programs.

[0117] In some embodiments, the access network device may be composed of a central unit (CU) and a distributed unit (DU). The CU may also be called a control unit. The CU-DU structure can separate the protocol layer of the access network device. Some of the protocol layer functions are centrally controlled by the CU, while the remaining part or all of the protocol layer functions are distributed in the DU and centrally controlled by the CU. However, this is not the only possibility.

[0118] In some embodiments, the core network equipment can be a single device, including a first network element, a second network element, etc., or it can be multiple devices or a group of devices, each including all or part of the first network element, the second network element, etc. Network elements can be virtual or physical. The core network includes, for example, at least one of the Evolved Packet Core (EPC), 5G Core Network (5GCN), and Next Generation Core (NGC).

[0119] It is understood that the communication system described in this disclosure is for the purpose of more clearly illustrating the technical solutions of this disclosure, and does not constitute a limitation on the technical solutions proposed in this disclosure. As those skilled in the art will know, with the evolution of system architecture and the emergence of new business scenarios, the technical solutions proposed in this disclosure are also applicable to similar technical problems.

[0120] The following embodiments of this disclosure can be applied to the communication system 100 shown in FIG1, or to some of the main bodies, but are not limited thereto. The main bodies shown in FIG1 are illustrative. The communication system may include all or some of the main bodies in FIG1, or may include other main bodies outside of FIG1. ​​The number and form of each main body are arbitrary.

[0122] In some embodiments, with the development of services such as AR / VR and high-definition video, the demand for downlink data by terminals is increasing. Previously, due to the limitations of cost and size, the number of transceivers actually deployed in terminals was limited. For example, some terminals could only support 4 receiving antennas (Receiver, Rx) and at most 4 MIMO layers (4x4 MIMO).

[0123] In some embodiments, considering the needs of some terminals (such as foldable screen terminals), UEs that support 6Rx need to support the functions of 6MIMO layers. Therefore, a UE capability indication signaling can be introduced to indicate to the network whether the UE supports 6MIMO layers, thereby improving the throughput of the UE.

[0143] In some embodiments, if the first information is used to indicate the number of MIMO layers supported by the terminal 101, the terminal 101 will send the first information regardless of whether it supports downlink reception of 6 MIMO layers. That is, step S2101 can be omitted and the terminal 101 can directly execute step S2102.

[0144] In some embodiments, the first information is used to indicate the number of data streams supported by the terminal 101 at the same time and frequency resources.

[0145] In some embodiments, the first information is used to indicate the maximum number of MIMO layers supported by the terminal 101 for downlink reception.

[0146] In some embodiments, the first information is used to indicate the maximum number of data streams that the terminal 101 can support with the same time and frequency resources.

[0147] In some embodiments, the first information may include the following fields:

[0148] 6MIMOlayers-Supported ENUMERATED{4layers,6layers}.

[0149] Optionally, this field may be referred to as a second field, a MIMO capability field, etc., and the name is not limited in the embodiments disclosed herein.

[0150] Optionally, the value of this field can be a string type, such as "4layers" or "6layers" as mentioned above, or it can be a numeric type, such as "0", "1", "4", or "6".

[0151] For example, when terminal 101 only supports downlink reception of 4MIMO layer, the value of the second field in the first information can be any one of "4layers", "0", or "4"; when terminal 101 supports downlink reception of 6MIMO layer and / or 4MIMO layer, the value of the second field in the first information can be any one of "4layers,6layers", "6layers", "0,1", "1", "4,6", or "6".

[0152] In some embodiments, the first information may be uplink control information (UCI) or system information (SI). Alternatively, the first information may be carried by either UCI or SI.

[0153] In some embodiments, the first information may be referred to as "capability indication information", "6MIMO layer support indication", etc., and the name is not limited in the embodiments disclosed herein.

[0154] In step S2102, terminal 101 sends first information to network device 102.

[0155] In some embodiments, network device 102 receives first information sent by terminal 101.

[0156] In some embodiments, network device 102 determines whether terminal 101 supports downlink reception at the 6MIMO layer based on whether it receives first information sent by terminal 101. Optionally, network device 102 determines whether terminal 101 supports downlink reception at the 6MIMO layer based on the received first information.

[0157] In some embodiments, network device 102 receives first information sent by terminal 101 and determines that terminal 101 supports downlink reception of 6MIMO layer.

[0158] In some embodiments, if the network device 102 does not receive the first information sent by the terminal 101, it determines that the terminal 101 does not support downlink reception of the 6MIMO layer.

[0159] In some embodiments, network device 102 receives first information including a first field and determines that terminal 101 supports downlink reception at the 6MIMO layer. Optionally, network device 102 receives first information excluding the first field and determines that terminal 101 does not support downlink reception at the 6MIMO layer.

[0160] In some embodiments, if the network device 102 determines that the terminal 101 supports downlink reception at the 6MIMO layer, it can modulate the downlink data using the corresponding modulation scheme and send it to the terminal 101. Optionally, if the network device 102 determines that the terminal 101 does not support downlink reception at the 6MIMO layer, it can modulate the downlink data using the modulation scheme corresponding to the 4MIMO layer or any other modulation scheme supported by the terminal 101 and send it to the terminal 101.

[0161] In some embodiments, network device 102 determines the number of downlink MIMO layers supported by terminal 101 based on first information.

[0162] In some embodiments, network device 102 determines whether terminal 101 supports downlink reception of the 6MIMO layer based on first information. Optionally, network device 102 determines whether terminal 101 supports downlink reception of the 6MIMO layer based on a second field in the first information.

[0163] In some embodiments, if the first information is used to indicate the number of downlink MIMO layers supported by the terminal 101, the network device 102 can determine the number of downlink MIMO layers supported by the terminal 101 based on the first information, and then determine whether the terminal 101 supports downlink reception with 6 MIMO layers.

[0164] For example, if the value of the second field in the first information is 4 layers, or 4, or 0, it is determined that terminal 101 does not support downlink reception of the 6MIMO layer. If the value of the second field in the first information is (or includes) at least one of 6 layers, 6, or 1, it is determined that terminal 101 supports downlink reception of the 6MIMO layer.

[0165] In some embodiments, if network device 102 determines that terminal 101 supports downlink reception at the 6MIMO layer, it can modulate the downlink data using a corresponding modulation scheme and send it to terminal 101. Optionally, if network device 102 determines that terminal 101 does not support downlink reception at the 6MIMO layer, it can modulate the downlink data using the modulation scheme corresponding to the 4MIMO layer or any other modulation scheme supported by terminal 101 and send it to terminal 101. In some embodiments, if network device 102 determines that terminal 101 supports downlink reception at the 6MIMO layer, it executes step S2103.

[0166] In step S2103, network device 102 sends second information to terminal 101.

[0167] In some embodiments, the second information is used to indicate the first performance requirement.

[0168] In some embodiments, the second information is used to instruct the terminal 101 to configure downlink reception to meet a first performance requirement.

[0169] In some embodiments, the first performance requirement is the PDSCH demodulation performance requirement corresponding to the downlink reception of the 6MIMO layer.

[0170] In some embodiments, the first performance requirement may be the minimum performance requirement for the terminal 101 to demodulate the downlink data (or PDSCH) modulated based on the modulation scheme corresponding to the 6MIMO layer sent by the network device 102.

[0171] In some embodiments, the first performance requirement includes at least one of the following: reference channel requirement; bandwidth requirement; subcarrier spacing requirement; modulation format requirement; coding rate requirement; propagation condition requirement; correlation matrix requirement; antenna configuration requirement; percentage of maximum throughput requirement; and signal-to-noise ratio (SNR) requirement.

[0172] For example, the primary performance requirements can be shown in Table 1 below:

[0173] Table 1

[0174] Referring to Table 1, when terminal 101 meets the first performance requirement, the reference channel used by terminal 101 can be the predefined "R.PDSCH.1-2.4FDD" channel, the bandwidth can be 10MHz, the subcarrier spacing can be 15kHz, the modulation and demodulation format can be 16QAM, the coding rate can be 0.48, the propagation conditions can meet the conditions corresponding to the TDLA30-10 channel model, the correlation matrix can be a 6x6 matrix, the antenna configuration requirements can meet the low uniform linear array (ULA Low) antenna configuration, the percentage of throughput is lower than X, and the SNR is lower than Y.

[0175] It is worth noting that TDLA30-10 can be a predefined channel model, which can be a Class A tapped delay line (TDL-A) with a delay spread of 30 nanoseconds (ns) and a Doppler frequency offset of 10 Hz.

[0176] Optionally, the percentage requirement for maximum throughput in the first performance requirement (e.g., the value of X) is greater than the percentage requirement for maximum throughput in the second performance requirement. Optionally, the SNR requirement in the first performance requirement (e.g., the value of Y) is greater than the SNR requirement in the second performance requirement. The second performance requirement refers to the PDSCH demodulation performance requirement corresponding to downlink reception in the 4MIMO layer.

[0177] The specific values ​​of X and Y are not limited in this embodiment of the invention. Those skilled in the art can set them according to actual needs, or the network device 102 can determine them according to actual conditions.

[0178] In some embodiments, the second information may also be referred to as "enhanced instruction information", "performance requirement instruction", etc., and the name is not limited in the embodiments disclosed herein.

[0179] In some embodiments, terminal 101 receives second information sent by network device 102.

[0180] In some embodiments, terminal 101 determines a first performance requirement based on second information.

[0181] In some embodiments, terminal 101 responds to the second information and executes step S2104.

[0182] In some embodiments, after the terminal 101 determines the first performance requirement based on the second information, it executes step S2104.

[0183] In some embodiments, the first performance requirement may be predefined by the protocol, meaning that the first performance requirement is known to terminal 101. In this case, network device 102 may not need to indicate the first performance requirement to terminal 101 through the second information.

[0184] Optionally, if the first performance requirement is predefined, step S2103 can be omitted, meaning the network device 102 does not need to instruct the terminal 101 to configure downlink reception to meet the first performance requirement via the second information. Optionally, if the network device 102 determines that the terminal 101 supports downlink reception at the 6MIMO layer, it can default that the downlink reception of the terminal 101 meets the first performance requirement.

[0185] In step S2104, terminal 101 configures downlink reception to meet the first performance requirement.

[0186] In some embodiments, the first performance requirement is determined by the terminal 101 based on the second information. Optionally, step S2104 is performed after the terminal 101 receives the second information.

[0187] In some embodiments, the first performance requirement is predefined by the protocol. Optionally, step S2104 is performed before or simultaneously with step S2101 or step S2102.

[0188] In some embodiments, if the terminal supports downlink reception of the 6MIMO layer, the terminal meets a predefined first performance requirement, which is the PDSCH demodulation performance requirement corresponding to the downlink reception of the 6MIMO layer.

[0189] For example, after configuring downlink reception to meet the first performance requirement, terminal 101 may determine that it supports downlink reception at the 6MIMO layer and execute steps S2101 and / or S2102.

[0190] In some embodiments, terminal 101 determines that a first performance requirement can be met and determines that downlink reception supports the 6MIMO layer. Optionally, terminal 101 determines that downlink reception supports the 6MIMO layer after configuring downlink reception to meet the first performance requirement.
