[0153] Step S2102 , terminal 101 sends first information to network device 102 .

[0154] In some embodiments, the network device 102 receives the first information sent by the terminal 101 .

[0155] In some embodiments, the network device 102 determines whether the terminal 101 supports downlink reception of the 6 MIMO layer according to whether the first information sent by the terminal 101 is received. Optionally, the network device 102 determines whether the terminal 101 supports downlink reception of the 6 MIMO layer according to the received first information.

[0156] In some embodiments, the network device 102 receives the first information sent by the terminal 101 and determines that the terminal 101 supports downlink reception of the 6 MIMO layer.

[0157] In some embodiments, the network device 102 does not receive the first information sent by the terminal 101, and determines that the terminal 101 does not support downlink reception of the 6 MIMO layer.

[0158] In some embodiments, the network device 102 receives the first information including the first field and determines that the terminal 101 supports downlink reception of the 6MIMO layer. Optionally, the network device 102 receives the first information not including the first field and determines that the terminal 101 does not support downlink reception of the 6MIMO layer.

[0159] In some embodiments, if the network device 102 determines that the terminal 101 supports downlink reception of the 6MIMO layer, the downlink data may be modulated using a corresponding modulation method and sent to the terminal 101. Optionally, if the network device 102 determines that the terminal 101 does not support downlink reception of the 6MIMO layer, the downlink data may be modulated using a modulation method corresponding to the 4MIMO layer or any other modulation method supported by the terminal 101 and sent to the terminal 101.

[0160] In some embodiments, the network device 102 determines the number of MIMO layers for downlink reception supported by the terminal 101 based on the first information.

[0161] In some embodiments, the network device 102 determines whether the terminal 101 supports downlink reception of the 6 MIMO layer according to the first information. Optionally, the network device 102 determines whether the terminal 101 supports downlink reception of the 6 MIMO layer according to the second field in the first information.

[0162] In some embodiments, if the first information is used to indicate the number of MIMO layers for downlink reception supported by terminal 101, network device 102 can determine the number of MIMO layers for downlink reception supported by terminal 101 based on the first information, and further determine whether terminal 101 supports 6 MIMO layers of downlink reception.

[0163] For example, if the value of the second field in the first information is 4layers or 4 or 0, it is determined that the terminal 101 does not support downlink reception of 6 MIMO layers. If the value of the second field in the first information is (or includes) at least one of 6layers, 6 or 1, it is determined that the terminal 101 supports downlink reception of 6 MIMO layers.

[0164] In some embodiments, the network device 102 determines that the terminal 101 supports downlink reception of the 6MIMO layer, and can use the corresponding modulation method to modulate the downlink data and send it to the terminal 101. Optionally, if the network device 102 determines that the terminal 101 does not support downlink reception of the 6MIMO layer, the downlink data is modulated using the modulation method corresponding to the 4MIMO layer or any other modulation method supported by the terminal 101 and sent to the terminal 101. In some embodiments, the network device 102 determines that the terminal 101 supports downlink reception of the 6MIMO layer, and executes step S2103.

[0165] Step S2103 , the network device 102 sends second information to the terminal 101 .

[0166] In some embodiments, the second information is used to indicate the first performance requirement.

[0167] In some embodiments, the second information is used to instruct the terminal 101 to configure downlink reception to meet the first performance requirement.

[0168] In some embodiments, the first performance requirement is a PDSCH demodulation performance requirement corresponding to downlink reception of the 6 MIMO layer.

[0169] 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 by the modulation method corresponding to the 6MIMO layer and sent by the network device 102 .

[0170] In some embodiments, the first performance requirement includes at least one of: reference channel requirement; bandwidth requirement; subcarrier spacing requirement; modulation format requirement; coding rate requirement; propagation condition requirement; correlation matrix requirement; antenna configuration requirement; maximum throughput percentage requirement; signal-to-noise ratio (SNR) requirement.

[0171] For example, the first performance requirement may be as shown in Table 1 below:

[0172] Table 1

[0173]

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

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

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

[0177] The specific values ​​of X and Y are not limited in the embodiments of the present disclosure, and those skilled in the art may set them according to actual needs, or the network device 102 may determine them according to actual conditions.

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

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

[0182] In some embodiments, after the terminal 101 determines the first performance requirement according to the second information, step S2104 is executed.

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

[0184] Optionally, when the first performance requirement is predefined, step S2103 can be omitted, that is, the network device 102 can configure the downlink reception to meet the first performance requirement without instructing the terminal 101 through the second information. Optionally, if the network device 102 determines that the terminal 101 supports the downlink reception of the 6MIMO layer, it can be assumed that the downlink reception of the terminal 101 meets the first performance requirement.

[0185] 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 according to 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 6 MIMO layers, the terminal meets a predefined first performance requirement, where the first performance requirement is a PDSCH demodulation performance requirement corresponding to the downlink reception of the 6 MIMO layers.

[0189] For example, after configuring the downlink reception to meet the first performance requirement, the terminal 101 may determine to support the downlink reception of 6 MIMO layers, and execute step S2101 and / or step S2102.

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