Description

Transmission waveform switching method, network equipment and user equipment

Technical field

The present disclosure relates to the field of communication technology, and in particular to a transmission waveform switching method, network equipment, user equipment, transmission waveform switching system, electronic equipment and non-volatile computer-readable storage media.

Background technique

The NR (New Radio, New Radio) system supports two transmission waveforms during uplink transmission: OFDM (DFT-S-OFDM, discrete Fourier transform-spread-orthogonal frequency division multiplexing) and OFDM (CP-OFDM, cyclic Prefix-Orthogonal Frequency Division Multiplexing).

The advantage of DFT-S-OFDM is low peak-to-average ratio and good power amplifier efficiency, but its disadvantage is that frequency domain resource allocation must be continuous and currently only supports single-stream transmission. Therefore, DFT-S-OFDM is more suitable for situations with poor channel conditions. For example, it can be used to serve cell edge users to improve coverage performance.

The advantage of CP-OFDM is that it supports non-continuous resource allocation and supports multi-stream transmission, which can provide higher data rates. But the disadvantage is that the average peak value is relatively high. Therefore, CP-OFDM is more suitable for situations with good channel conditions. Such as serving users near or in the middle of the community to increase system capacity.

As mentioned before, the semi-static uplink transmission waveform switching mechanism cannot dynamically match the actual channel status, resulting in transmission performance loss.

In view of the above technical problems, the present disclosure proposes a method for dynamic switching of uplink channel transmission waveforms, which can realize dynamic switching of uplink transmission waveforms.

Moreover, the technical solution of the present disclosure can also solve other technical problems caused by dynamic waveform switching. For example, when DCI schedules corresponding uplink transmission, the contents of certain fields are related to the transmission waveform used, and the UE's understanding of the size of each DCI field is based on the RRC configuration. Therefore, there may be technical problems in which the UE and the network equipment have inconsistent understanding.

For example, the technical solution of the present disclosure can be implemented through the following embodiments.

FIG. 1 shows a flowchart of some embodiments of a transmission waveform switching method of the present disclosure.

As shown in Figure 1, in step 110, the network device sends control information to the UE that supports uplink channel waveform switching. The control information is used to indicate to the UE the uplink transmission waveform it needs to use.

In some embodiments, indication signaling is sent to the UE, and the indication signaling is used to instruct the UE whether to enable uplink channel waveform switching; when the UE enables uplink channel waveform switching according to the indication signaling, control information is sent to the UE.

In some embodiments, the network device indicates whether dynamic switching of the uplink channel transmission waveform is enabled through signaling.

For example, the signaling may include RRC signaling. The RRC signaling may include a 1-bit field used to indicate turning off or turning on uplink channel transmission waveform dynamic switching. For example, the value of this field can be "0" or "1", indicating respectively turning off and turning on the dynamic switching of the uplink channel transmission waveform.

In some embodiments, the control information is used to indicate the uplink transmission waveform that the UE needs to use for the first uplink transmission, and the first uplink transmission is the currently scheduled uplink transmission.

For example, the network device dynamically indicates the waveform used for uplink transmission through DCI, and only indicates the waveform used for scheduled uplink transmission.

In some embodiments, the control information is used to indicate the uplink transmission waveform that the UE needs to adopt for the first uplink transmission and the second uplink transmission, and the second uplink transmission is different from the first uplink transmission. For example, the second uplink transmission is determined through periodic configuration or SPS.

For example, the network device dynamically indicates the waveform used for uplink transmission through DCI, indicating the waveform used for scheduled uplink transmission and the waveform used for other uplink transmission. For example, other uplink transmissions are configured periodically by network equipment or semi-statically scheduled (SPS).

In some embodiments, the control information is used to instruct the UE to switch the uplink transmission waveform configured by RRC to the uplink transmission waveform that needs to be used.

For example, when the uplink channel transmission waveform dynamic switching function is turned on, the uplink transmission waveform indicated by the DCI overwrites the uplink transmission waveform configured by the RRC.

In some embodiments, the control information is used to instruct the UE to use the uplink transmission waveform that needs to be used for uplink transmission until RRC is used again to configure the uplink transmission waveform or the control information is used again to indicate the uplink transmission waveform that needs to be used.

For example, it indicates the waveform used for other uplink transmissions, and the valid time of the indication lasts until the next RRC reconfiguration or the next DCI dynamic indication.

In some embodiments, the control information is DCI, and the DCI includes a designated field used to indicate information related to the uplink transmission waveform that needs to be used.

In some embodiments, when the uplink channel transmission waveform dynamic switching function is turned on, for UEs that support waveform dynamic switching, the network device dynamically indicates the waveform used for uplink transmission through DCI.

For example, the DCI format includes at least one of the following: DCI 0_0, DCI 0_1, DCI 0_2.

In some embodiments, waveform indication information may be included in the DCI explicitly or implicitly.

In some embodiments, the designated field is a newly added field, and the new field includes information about the uplink transmission waveform that needs to be used, or the designated field is an existing field, and the existing field includes information about the uplink transmission waveform that needs to be used. Related Information.

For example, when the designated field is a newly added field, the newly added information field includes identification information of the uplink transmission waveform that needs to be used, or the new information field is used to indicate whether the uplink transmission waveform that needs to be used is consistent with RRC. The configured uplink transmission waveforms are consistent.

For example, when the waveform indication information is explicitly included in the DCI, a 1-bit information field is added to the DCI, which is used solely for waveform information indication. For example, bit "0" indicates the first transmission waveform, and bit "1" indicates the second transmission waveform; or bit "0" indicates that the current waveform is consistent with the RRC configured waveform, and bit "1" indicates that the current waveform is inconsistent with the RRC configured waveform. , switch to another waveform not configured by RRC.

In some embodiments, considering that the DCI field sizes corresponding to different transmission waveforms may be inconsistent, the waveform information indication field may be configured after the DCI format identifier (Identifier for DCI formats) field, the precoding information and the number of layers (Precoding information and number of layers) fields.

In this way, the UE can avoid misunderstanding of some DCI fields.

In some embodiments, when the specified field is an existing field, the existing field includes an SRI field.

In some embodiments, when the waveform indication information is implicitly included in the DCI, certain existing DCI fields can be reused to indicate the uplink transmission waveform to be used. For example, include the SRI field among the existing fields. Multiplexing some existing DCI field bits may include reserved bits of the SRI field.

In some embodiments, in step 120, the UE switches the uplink transmission waveform it is currently using to the uplink transmission waveform it needs to use according to the control information.

In some embodiments, when the uplink channel transmission waveform dynamic switching function is turned on, for a UE that supports waveform dynamic switching, after decoding to obtain the corresponding DCI information, the UE determines that the uplink transmission waveform is the first transmission according to the waveform indication information in the DCI. waveform or second transmission waveform, and then parse the contents of each field of the DCI.

For example, the first transmission waveform is DFT-S-OFDM, and the second transmission waveform is CP-OFDM.

In some embodiments, the specific indication of the uplink transmission waveform may be replaced by changing whether the precoder is turned on. For example, the first transmission waveform or the second transmission waveform can be used by turning on or off the transform precoder. When the transform precoder is enabled, it is equivalent to using the first transmission waveform (DFT-S-OFDM); when the transform precoder is disabled, it is equivalent to using the second transmission waveform. (CP-OFDM).

In some embodiments, when the currently used uplink transmission waveform is inconsistent with the uplink transmission waveform that needs to be used, the UE is scheduled according to the UE's waveform switching capability to switch the currently used uplink transmission waveform to the need to use the uplink transmission waveform. .

For example, according to the time information required by the UE to switch waveforms reported by the UE, the UE is scheduled to switch the currently used uplink transmission waveform to the uplink transmission waveform that needs to be used.

For example, when the network device dynamically indicates the waveform used for uplink transmission through DCI, if the uplink transmission waveform dynamically indicated by DCI is inconsistent with the uplink transmission waveform currently used by the user, the network device needs to schedule the user based on the UE's waveform switching capability. The corresponding waveform switches. For example, the waveform switching capability is reported by the UE to the network device. The waveform switching capability can be the switching time required for the UE to switch from a certain transmission waveform to another transmission waveform.

In this way, it can be ensured that the UE has enough time to complete uplink waveform switching at the beginning of the scheduling time.

FIG. 2 shows a flow chart of some other embodiments of the transmission waveform switching method of the present disclosure.

As shown in Figure 2, in step 210, the network device indicates through signaling whether dynamic switching of the uplink channel transmission waveform is enabled.

For example, the above signaling may include RRC signaling.

For example, the above signaling indication may include 1 bit. “0” and “1” respectively indicate turning off and turning on the dynamic switching of the uplink channel transmission waveform.

In step 220, when the uplink channel transmission waveform dynamic switching function is turned off, the behaviors and various processing procedures of the network equipment and UE remain the same as before the introduction of the waveform dynamic switching function.

In step 230, when the uplink channel transmission waveform dynamic switching function is turned on, for UEs that support waveform dynamic switching, the network device dynamically indicates the waveform to be used for uplink transmission through DCI.

For example, the DCI format includes at least one of the following: DCI 0_0, DCI 0_1, DCI 0_2.

For example, when the uplink channel transmission waveform dynamic switching function is turned on, the uplink transmission waveform indicated by the DCI overwrites the uplink transmission waveform configured by the RRC.

In some embodiments, the network device dynamically indicates only the waveform that the scheduled uplink transmission needs to use through DCI.

In some embodiments, the network device dynamically indicates the waveform used for scheduled uplink transmission and the waveform used for other uplink transmission through DCI. For example, the other uplink transmissions mentioned above are configured periodically by the network device or semi-statically scheduled (SPS).

For example, the validity time of the indication lasts until the next RRC reconfiguration or the next DCI dynamic indication.

In some embodiments, if the waveform of the DCI dynamic indication is inconsistent with the uplink transmission waveform currently used by the user, the network device needs to schedule the user to perform corresponding waveform switching based on the UE's waveform switching capability. In this way, it can be ensured that the UE has enough time to complete uplink waveform switching at the beginning of the scheduling time. For example, the waveform switching capability reported by the UE to the network device may be the switching time required for the UE to switch from a certain transmission waveform to another waveform.

In step 240, when the uplink channel transmission waveform dynamic switching function is turned on, for a UE that supports waveform dynamic switching, after decoding to obtain the corresponding DCI information, the UE determines that the uplink transmission waveform is the first transmission waveform or the first transmission waveform according to the waveform indication information in the DCI. The second transmission waveform is used to analyze the contents of each field of the DCI.

For example, the first transmission waveform is DFT-S-OFDM, and the second transmission waveform is CP-OFDM.

In some embodiments, waveform indication information may be included in the DCI information explicitly or implicitly.

For example, waveform indication information is explicitly included in the DCI. DCI adds a new 1-bit information field, which is used solely for waveform information indication. For example, bit "0" indicates the first transmission waveform, and bit "1" indicates the second transmission waveform; or bit "0" indicates that the current waveform is consistent with the RRC configured waveform, and bit "1" indicates that the current waveform is inconsistent with the RRC configured waveform. , switch to another waveform not configured by RRC.

For example, since the DCI field sizes corresponding to different transmission waveforms may be inconsistent, the waveform information indication field may be configured after the DCI format identifier field and before the precoding information and layer number fields. In this way, it is possible to prevent the UE from misunderstanding some fields of the DCI.

For example, the waveform indication information is implicitly included in the DCI, and some existing DCI fields can be reused to indicate the current transmission waveform. For example, multiplexing some existing DCI field bits includes reserved bits of the SRI field.

FIG. 3 shows a flow chart of some further embodiments of the transmission waveform switching method of the present disclosure.

As shown in Figure 3, in step 310, the UE that supports uplink channel waveform switching receives control information sent from the network device.

In step 320, the UE switches the currently used uplink transmission waveform to the uplink transmission waveform that needs to be used according to the control information sent by the network device. The control information is used to indicate to the UE the uplink transmission waveform that it needs to use.

In some embodiments, the UE determines whether to enable uplink channel waveform switching according to the instruction signaling sent by the network device; according to the control information sent by the network device, switches the currently used uplink transmission waveform to the uplink transmission waveform that needs to be used, including: : When the UE enables uplink channel waveform switching according to the instruction signaling, the UE switches the currently used uplink transmission waveform to the uplink transmission waveform that needs to be used.

In some embodiments, when the currently used uplink transmission waveform is inconsistent with the uplink transmission waveform that needs to be used, the currently used uplink transmission waveform is switched to the need to use the uplink transmission waveform according to the scheduling of the network device. Scheduling is determined based on the UE's waveform switching capability.
