Description

Switching method of transmission waveform, network equipment and user equipment

Technical Field

The present disclosure relates to the field of communications technologies, and in particular, to a transmission waveform switching method, a network device, a user device, a transmission waveform switching system, an electronic device, and a non-volatile computer readable storage medium.

Background

An NR (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 DFT-S-OFDM has advantages of low peak-to-average ratio and good power amplification efficiency, but has disadvantages in that frequency domain resource allocation must be continuous and only single stream transmission is supported at present. Therefore, DFT-S-OFDM is more suitable for the situation that the channel condition is worse. Such as for serving cell edge users, to improve coverage performance.

The CP-OFDM has advantages in that it supports discontinuous resource allocation and supports multi-stream transmission, which can provide higher data rates. But has the disadvantage of a relatively high peak-to-average ratio. Therefore, CP-OFDM is better suited for situations where channel conditions are better. Such as serving cell near and mid-point users, to increase system capacity.

In the related art, only semi-static configuration uplink transmission waveforms through RRC (Radio Resource Control ) signaling are supported according to the 3GPP (3 rd Generation Partnership Project, third generation partnership project) Rel-17 (Release-17, release 17) protocol.

Detailed Description

Various exemplary embodiments of the present disclosure will now be described in detail with reference to the accompanying drawings. It should be noted that: the relative arrangement of the components and steps, numerical expressions and numerical values set forth in these embodiments do not limit the scope of the present disclosure unless it is specifically stated otherwise.

Meanwhile, it should be understood that the sizes of the respective parts shown in the drawings are not drawn in actual scale for convenience of description.

The following description of at least one exemplary embodiment is merely illustrative in nature and is in no way intended to limit the disclosure, its application, or uses.

Techniques, methods, and apparatus known to one of ordinary skill in the relevant art may not be discussed in detail, but where appropriate, the techniques, methods, and apparatus should be considered part of the specification.

In all examples shown and discussed herein, any specific values should be construed as merely illustrative, and not a limitation. Thus, other examples of the exemplary embodiments may have different values.

It should be noted that: like reference numerals and letters denote like items in the following figures, and thus once an item is defined in one figure, no further discussion thereof is necessary in subsequent figures.

As previously described, the semi-static uplink transmit waveform switching mechanism cannot dynamically match the actual channel conditions, resulting in a loss of transmission performance.

Aiming at the technical problems, the disclosure provides a dynamic switching method of uplink channel transmission waveforms, which can realize dynamic switching of uplink transmission waveforms.

Moreover, the technical scheme of the present disclosure can also solve other technical problems due to dynamic waveform switching. For example, when DCI schedules corresponding uplink transmission, the content of some fields is related to the employed transmission waveform, and the UE's understanding of the size of each field of DCI is based on RRC configuration, so there may be a technical problem that the UE and the network device understand inconsistently.

For example, the technical solution of the present disclosure may be implemented by the following embodiments.

Fig. 1 illustrates a flow chart of some embodiments of a method of switching transmission waveforms of the present disclosure.

As shown in fig. 1, in step 110, the network device sends control information to the UE supporting uplink channel waveform switching, where the control information is used to indicate to the UE the uplink transmission waveform that it needs to employ.

In some embodiments, an indication signaling is sent to the UE, where the indication signaling is used to indicate whether the UE starts uplink channel waveform switching; and under the condition that the UE starts the uplink channel waveform switching according to the indication signaling, the control information is sent to the UE.

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

For example, the signaling may include RRC signaling. The RRC signaling may include a 1-bit field to indicate whether to turn off or turn on uplink channel transmission waveform dynamic switching. For example, the value of this field may be "0" or "1" indicating that the uplink channel transmit waveform is switched dynamically off and on, respectively.

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

In some embodiments, the control information is used to indicate uplink transmission waveforms that the UE needs to employ on a first uplink transmission and a second uplink transmission, the second uplink transmission being different from the first uplink transmission. The second uplink transmission is determined, for example, by periodic configuration or SPS.

For example, the network device dynamically indicates, through DCI, a waveform employed for uplink transmission, indicates a waveform employed for scheduled uplink transmission and a waveform employed for other uplink transmissions. For example, other uplink transmissions are periodically configured by the network device or semi-persistent scheduling (SPS).

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

For example, the waveform employed for other uplink transmissions is indicated, and the indicated validity time is continued until the next RRC reconfiguration or the next DCI dynamic indication.

In some embodiments, when the uplink channel transmission waveform dynamic switching function is turned on, for a UE supporting waveform dynamic switching, the network device dynamically indicates, through DCI, a waveform employed for uplink transmission.

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

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

For example, in the case that the designated field is a newly added field, the newly added information field includes identification information of an uplink transmission waveform to be employed, or the newly added information field is used to indicate whether the uplink transmission waveform to be employed is consistent with an uplink transmission waveform configured by RRC.

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

In some embodiments, the waveform information indication field may be configured after the DCI format identifier (Identifier for DCI formats) field, before the precoding information and layer number (Precoding information and number of layers) field, considering that DCI field sizes corresponding to different transmission waveforms may not be uniform.

In this way, the UE can be prevented from understanding the DCI part field in error.

In some embodiments, where the waveform indication information is implicitly contained in the DCI, certain existing DCI fields may be multiplexed to indicate the uplink transmission waveform that needs to be employed. For example, an SRI field is included in the existing field. Multiplexing existing certain DCI field bits may include reserved bits of the SRI field.

In some embodiments, in step 120, the UE switches the uplink transmission waveform currently adopted by the UE to the uplink transmission waveform to be adopted according to the control information.

In some embodiments, when the uplink channel transmission waveform dynamic switching function is turned on, for a UE supporting waveform dynamic switching, after decoding to obtain corresponding DCI information, the UE determines, according to waveform indication information in DCI, that the uplink transmission waveform is a first transmission waveform or a second transmission waveform, so as to analyze contents of fields 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 whether the alternative uplink transmission waveform is on may be by way of a transform precoder. For example, the use of the first transmission waveform or the second transmission waveform may be achieved by switching the transform precoder on or off. When the transform precoder is on (transform precoder is enabled), corresponding to employing a first transmission waveform (DFT-S-OFDM); when the transform precoder is turned off (transform precoder is disabled), this corresponds to the use of a second transmission waveform (CP-OFDM).

In some embodiments, when the currently adopted uplink transmission waveform is inconsistent with the uplink transmission waveform to be adopted, the UE is scheduled according to the waveform switching capability of the UE, and the currently adopted uplink transmission waveform is switched to the uplink transmission waveform to be adopted.

For example, according to the time information required by the UE switching waveform reported by the UE, the UE is scheduled to switch the currently adopted uplink transmission waveform to the uplink transmission waveform to be adopted.

For example, in the process that the network device dynamically indicates the waveform adopted by the uplink transmission through the DCI, if the uplink transmission waveform dynamically indicated by the DCI is inconsistent with the uplink transmission waveform currently adopted by the user, the network device needs to schedule the user to perform corresponding waveform switching according to the waveform switching capability of the UE. For example, the waveform switching capability is reported by the UE to the network device, which may be the switching time required for the UE to switch from one transmit waveform to another.

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

Fig. 2 shows a flow chart of further embodiments of a switching method of a transmission waveform of the present disclosure.

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

For example, the signaling described above may include RRC signaling.

For example, the signaling indication may comprise 1 bit. "0" and "1" indicate the dynamic switching of the transmission waveforms of the closed and open uplink channels, respectively.

In step 220, when the uplink channel transmission waveform dynamic switching function is turned off, the behavior of the network device and the UE and various processing flows are consistent with those before the waveform dynamic switching function is introduced.

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

In some embodiments, the network device dynamically indicates only the waveforms that the scheduled uplink transmission needs to take over via DCI.

In some embodiments, the network device dynamically indicates the waveform employed for scheduled uplink transmissions and the waveforms employed for other uplink transmissions via DCI. For example, the other uplink transmissions described above are periodically configured or semi-persistent scheduling (SPS) by the network device.

For example, the indicated validity time continues until the next RRC reconfiguration or the next DCI dynamic indication.

In some embodiments, if the waveform dynamically indicated by the DCI is inconsistent with the uplink transmission waveform currently adopted by the user, the network device needs to schedule the user to perform corresponding waveform switching according to the waveform switching capability of the UE. In this way, it can be ensured that the UE has enough time to complete the uplink waveform switching at the beginning of the scheduling instant. For example, the waveform switching capability may be reported by the UE to the network device as the switching time required for the UE to switch from one transmit waveform to another.

In step 240, when the uplink channel transmission waveform dynamic switching function is turned on, for the UE supporting waveform dynamic switching, after the UE decodes to obtain the corresponding DCI information, the UE determines that the uplink transmission waveform is the first transmission waveform or the second transmission waveform according to the waveform indication information in the DCI, so as to analyze the content of each field of the DCI.

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

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

For example, since DCI field sizes corresponding to different transmission waveforms may not be uniform, a waveform information indication field may be configured after a DCI format identifier field, precoding information, and before a layer number field. In this way, the UE can be prevented from understanding the DCI partial field in error.

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

Fig. 3 illustrates a flow chart of yet other embodiments of a method of switching transmission waveforms of the present disclosure.

As shown in fig. 3, in step 310, a UE supporting uplink channel waveform switching receives control information transmitted from a network device.

In step 320, the UE switches the currently adopted uplink transmission waveform to the uplink transmission waveform to be adopted according to the control information sent by the network device, where the control information is used to indicate the uplink transmission waveform to be adopted to the UE.

In some embodiments, the UE determines whether to start uplink channel waveform switching according to an indication signaling sent by the network device; switching the currently adopted uplink transmission waveform to the uplink transmission waveform to be adopted according to the control information sent by the network equipment comprises the following steps: and under the condition that the UE starts uplink channel waveform switching according to the indication signaling, the UE switches the currently adopted uplink transmission waveform to the uplink transmission waveform to be adopted.

In some embodiments, when the uplink transmission waveform currently adopted is inconsistent with the uplink transmission waveform to be adopted, the uplink transmission waveform currently adopted is switched to the uplink transmission waveform to be adopted according to the scheduling of the network device, and the scheduling of the network device is determined according to the waveform switching capability of the UE.
