[0117] For example, as shown in FIG1c , in some cases, the PAPR of the DFT-S-OFDM waveform is approximately 3 decibels (dB) lower than the PAPR of the CP-OFDM waveform.

[0118] Therefore, the DFT-S-OFDM waveform is more suitable for scenarios with limited uplink coverage, such as cell-edge users. For example, in frequency range (FR) 2, the DFT-S-OFDM waveform has better uplink coverage.

[0119] In some embodiments, one bit is added to downlink control information (DCI) to indicate a specific uplink scheduling PUSCH channel transmission waveform.

[0120] In some embodiments, due to high-order modulation and transmission bandwidth configurations, a maximum transmit power reduction allowed for a terminal is defined. For example, for terminal power class (PC) 2, Table 1 defines the maximum power reduction (MPR) allowed for channel bandwidths that meet the following two criteria; for PC 3, Table 2 defines the maximum power reduction (MPR) allowed for channel bandwidths that meet the following two criteria.

[0121] Table 1

[0122] Table 2

[0123] In some embodiments, the additional emission requirement may be notified to the terminal via network signaling. Each additional emission requirement is associated with a unique network signaling (NS) value, which is indicated in RRC signaling by the NR band number of the applicable operating frequency band and the associated value in the field. For example, the NR band number of the applicable operating frequency band and the associated value in the field may be additional spectrum emission.

[0124] For example, to meet additional requirements, additional maximum power reduction is allowed for the maximum output power specified in Table 1 and / or Table 2.

[0125] (Additional Maximum Power Reduction, A-MPR). Unless otherwise specified, the total reduction in maximum transmission power of a terminal is the maximum of MPR and A-MPR. MPR refers to the above description.

[0126] In some embodiments, the terminal is allowed to set the configured maximum output power for the carrier of the serving cell in each time slot. For example, the configured maximum output power P is set for the carrier f of the serving cell c. CMAX,f,c .

[0127] Optionally, P CMAX,f,c The value of P CMAX_L,f,c and P CMAX_H,f,c Between. That is Among them, P C,MAXC,f,cM is the maximum transmit power, P CMAX_L,f,c is the lower value of the maximum transmit power, P CMAX_H,f,c The high value of the maximum transmit power.

[0128] Optionally, P CMAX_L,f,c Determined based on Formula 1: P CMAX_L,f,c =MIN{P EMAX,c -ΔT C,c (P PowerClass -ΔP PowerClass )-MAX(MAX(MPR c +ΔMPR c ,A-MPR c )+ΔT IB,c +ΔT C,c +ΔT RxSRS, P-MPR c )} Formula 1

[0129] Where f represents the carrier frequency, c represents the serving cell, and P EMAX,c Indicates the maximum allowable power of the network device configuration, P PowerClassIndicates the terminal defined power without considering other non-ideal factors (tolerance), ΔP PowerClass Indicates that the maximum power of the terminal is reduced or the power fallback value is configured based on the duty cycle to ensure RF radiation exposure, MPR c Indicates the maximum power reduction due to modulation mode and transmission bandwidth configuration factors, A-MPR c Indicates the additional power backoff required by network signaling to ensure the relevant radiation requirements of different operating frequency bands, ΔT IB,c Indicates the additional power back-off value under multi-carrier, ΔT C,c Indicates the additional power backoff value corresponding to the transmission of special edge configuration, ΔT RxSRS Indicates the terminal power adjustment value related to SRS antenna switching, P-MPR c Indicates the maximum power reduction of power management.

[0130] Optionally, P CMAX_H,f,c Determined based on Formula 2: P CMAX_H,f,c =MIN{P EMAX,c ,P PowerClass -ΔP PowerClass} Formula 2

[0131] In some embodiments, the terminal may report a power headroom report (PHR). The PHR may include power headroom (PH), maximum transmit power P CMAX,f,c and power management maximum power reduction (P-MPR). The power headroom reflects the amount of additional transmit power that the terminal can transmit with reference to the current PUSCH power level, and P CMAX,f,c It reflects the maximum power that the terminal can deliver in this situation. The current protocol stipulates that P-MPR is only reported for the FR2 band. It can be understood that PHR provides instantaneous information about a set of parameters for reporting specific PUSCH transmissions of network devices.

[0132] For example, Figure 1d shows the currently specified PHR configuration format for a single carrier. The P indication field is used to indicate whether there is MPE; the reserved bit can be denoted as R. It can be understood that the reserved bit usually does not contain any information and is mainly used to record the corresponding newly added data when necessary. The power margin is the above-mentioned PH, where in the case of a single carrier, the PH information corresponds to the PUSCH of the terminal, that is, type 1. At the same time, the PH is the PH corresponding to the primary cell (PCell). MPE or reserved bit indicates that this field can be MPE-related information or a reserved bit. Among them, the MPE-related information is used to record P-MPR in the case of FR2.

[0133] For another example, Figure 1e shows the PHR configuration format in a multi-carrier case. Among them, C1 to C7 can be used to indicate the PHR corresponding to different carriers respectively. It can be understood that the multi-carrier PHR can be regarded as a combination of multiple single-carrier PHRs. Type 2 can correspond to the physical uplink control channel (PUCCH), and the special cell (SpCell) can include a PCell and a primary secondary cell (PSCell). The serving cell can be a PCell, a secondary cell (SCell), a PSCell, or a SpCell, etc.

[0134] In some embodiments, two uplink waveforms are supported for PUSCH transmission: CP-OFDM and DFT-S-OFDM. Compared to CP-OFDM, DFT-S-OFDM is more suitable for uplink coverage-limited scenarios, such as cell-edge users, due to its lower PAPR. Therefore, dynamic switching between the CP-OFDM and DFT-S-OFDM waveforms is possible.

[0135] In some embodiments, switching between waveforms also involves switching the number of transmission data layers (ranks). For example, the DFT-S-OFDM waveform in NR currently only supports PUSCH transmission data layers of 1, while the CP-OFDM waveform can support PUSCH transmission data layers greater than 1. Therefore, when dynamically switching uplink transmission waveforms, the transmission data layers of different waveforms may be incompatible. For dynamic waveform switching (DWS) decisions, whether and how to support rank switching is an issue that needs to be addressed.

[0136] FIG2 is an interactive diagram of a communication method according to an embodiment of the present disclosure. As shown in FIG2 , the embodiment of the present disclosure relates to a communication method for use in a communication system 100, the method comprising:

[0137] Step S2101 , the network device 102 sends first information to the terminal 101 .

[0138] In some embodiments, the terminal 101 receives first information sent by the network device 102 .

[0139] In some embodiments, terms such as "send", "transmit", "report", "download", "transmit", "bidirectional transmission", "send and / or receive" can be used interchangeably.

[0140] In some embodiments, "obtain", "get", "get", "receive", "transmit", "bidirectional transmission", "send and / or receive" can be interchangeable, and can be interpreted as receiving from other entities, obtaining from protocols, obtaining from higher layers, obtaining by self-processing, autonomous implementation, etc.

[0141] In some embodiments, the first information is used to instruct the terminal to send a sounding reference signal (SRS) resource set. The SRS resource set is used by the terminal to send a DWS command for a PUSCH. The SRS resource set includes one or more multi-port SRS resources.

[0142] In some embodiments, terms such as "uplink", "uplink", "physical uplink" can be interchangeable with each other, and terms such as "downlink", "downlink", "physical downlink" can be interchangeable with each other, and terms such as "side", "sidelink", "side communication", "sidelink communication", "direct connection", "direct link", "direct communication", "direct link communication" can be interchangeable with each other.

[0143] In some embodiments, the SRS resource set can be used by the network device 102 to obtain uplink channel state information. The network device determines the rank of the terminal sending the PUSCH based on the uplink channel state information. For example, if the rank of the current terminal sending the PUSCH is 1, the network device obtains the uplink channel state information based on the SRS resource set sent by the terminal, and determines that the rank is 2 based on the uplink channel state information, then the network device can schedule the terminal to switch the rank from 1 to 2. For another example, the network device can schedule the terminal to switch the rank from 1 to 2 in the DWS, that is, to achieve simultaneous switching of the uplink transmission waveform and rank.

[0144] In some embodiments, the number of multiple-input multiple-output (MIMO) ranks supported by the uplink transmission waveform may be one or more.

[0145] In some embodiments, the uplink transmission waveform includes a CP-OFDM waveform and a DFT-S-OFDM waveform.

[0146] In some embodiments, when the MIMO rank supported by DFT-S-OFDM is one, for example, it can support switching from a DFT-S-OFDM waveform with a rank of 1 to a CP-OFDM waveform with a rank greater than 1. For another example, it can support switching from a CP-OFDM waveform with a rank greater than 1 to a DFT-S-OFDM waveform with a rank of 1.

[0147] In some embodiments, a set of SRS resources whose function is DWS may be predefined.

[0148] In some embodiments, the SRS resource set sent by the first information indication terminal may be one or more multi-port SRS resources in an SRS resource set configured as a DWS function.

[0149] In some embodiments, the SRS resource set sent by the first information indication terminal may be one or more multi-port SRS resources in an SRS resource set whose configuration function is a codebook.

[0150] In some embodiments, the SRS resource set sent by the first information indication terminal may be one or more multi-port SRS resources in an SRS resource set configured as antenna switching. The number of ports is greater than 1. For example, an SRS resource set configured as xTyR antenna switching, where x and y represent the number of ports, T represents transmission, R represents reception, and x is greater than 1. For example, 8T8R corresponds to an 8-port SRS resource combination, and 4T4R corresponds to a 4-port SRS resource set. However, the above-mentioned 4-port SRS resource set and 8-port SRS resource set in the present disclosure are only examples and are not limiting.

[0151] In some embodiments, on the same carrier, no other SRS resource sets are transmitted in the time domain transmission symbols occupied by the SRS resource set for DWS, that is, the SRS resource set for DWS and other SRS resource sets do not overlap in time domain configuration.

[0152] In some embodiments, the first information is used to instruct the terminal to transmit a first PUSCH, a second PUSCH, and an SRS resource set, wherein the first PUSCH is transmitted using a first waveform and the second PUSCH is transmitted using a second waveform.

[0153] In some embodiments, the first PUSCH and the second PUSCH may be PUSCHs based on codebook transmission or PUSCHs based on non-codebook transmission.

[0154] In some embodiments, the first information may be a plurality of consecutive pieces of information, respectively used to instruct the terminal to send the first PUSCH, the second PUSCH and the SRS resource set.

[0155] In some embodiments, among the consecutive first information, the first information for indicating the transmission of the SRS resource set may be transmitted before the first information for indicating the transmission of the first PUSCH and the first information for indicating the transmission of the second PUSCH.

[0156] In some embodiments, among multiple consecutive first information, the first information for instructing the transmission of an SRS resource set may be transmitted between the first information for instructing the transmission of a first PUSCH and the first information for instructing the transmission of a second PUSCH. For example, terminal 101 receives multiple consecutive first information sent by network device 102, wherein the first first information is used to instruct the terminal to transmit a first PUSCH; the second first information is used to instruct the terminal to transmit an SRS resource set; and the third first information is used to instruct the terminal to transmit a second PUSCH.

[0157] In some embodiments, among multiple consecutive first information, the first information for instructing the transmission of an SRS resource set may be transmitted after the first information for instructing the transmission of a first PUSCH and the first information for instructing the transmission of a second PUSCH. For example, terminal 101 receives multiple consecutive first information sent by network device 102, wherein the first first information is used to instruct the terminal to transmit a first PUSCH; the second first information is used to instruct the terminal to transmit a second PUSCH; and the third first information is used to instruct the terminal to transmit an SRS resource set.

[0158] In some embodiments, the first information may be used to simultaneously instruct the terminal to transmit a first PUSCH and an SRS resource set. For example, terminal 101 receives multiple consecutive first information messages sent by network device 102, wherein the first first information is used to instruct the terminal to transmit a first PUSCH and an SRS resource set, and the SRS resource set may be transmitted before or after the first PUSCH; and the second first information is used to instruct the terminal to transmit a second PUSCH.

[0159] In some embodiments, the first information may be used to simultaneously instruct the terminal to transmit a second PUSCH and an SRS resource set. For example, terminal 101 receives multiple consecutive first information messages sent by network device 102, wherein the first first information message is used to instruct the terminal to transmit a first PUSCH; the second first information message is used to instruct the terminal to transmit an SRS resource set and a second PUSCH. The SRS resource set may be transmitted before or after the second PUSCH.

[0160] In some embodiments, the first information is used to instruct the terminal to transmit the first PUSCH, the second PUSCH, and the SRS resource set in the first time slot and the second time slot. The SRS resource set only needs to be transmitted once to save uplink symbol allocation resources or to avoid repeated transmission of the SRS resource set when there is a periodic SRS (P-SRS) or semi-persistent SRS (SP-SRS) resource set in the next adjacent time slot.

[0161] In some embodiments, the first information may be used to indicate that an SRS resource set is to be transmitted in the first time slot. For example, the first information may indicate that the terminal transmits a first PUSCH and an SRS resource set in the first time slot and a second PUSCH in the second time slot. In the first time slot, the terminal may transmit the first PUSCH first and then the SRS resource set, or may transmit the SRS resource set first and then the first PUSCH.

[0162] In some embodiments, the first information may be used to indicate that an SRS resource set is to be transmitted in the second time slot. For example, the first information may indicate that the terminal transmits a first PUSCH in the first time slot and a second PUSCH and an SRS resource set in the second time slot. The terminal may transmit the second PUSCH first and then the SRS resource set in the second time slot, or may transmit the SRS resource set first and then the second PUSCH.

[0163] Of course, it is understandable that the first information may also instruct the terminal to send the SRS resource set in both the first time slot and the second time slot, and the present disclosure does not limit this.

[0164] In some embodiments, the first information is used to instruct the terminal to send the first PUSCH, the second PUSCH, and the SRS resource set in different time slots, where the different time slots are adjacent time slots, that is, the first time slot and the second time slot are adjacent time slots.

[0165] In some embodiments, the SRS resource set sent by the terminal may be a P-SRS resource set.

[0166] In some embodiments, the SRS resource set sent by the terminal may be an SP-SRS resource set.

[0167] In some embodiments, the SRS resource set sent by the terminal may be an aperiodic SRS (AP-SRS) resource set.

[0168] In some embodiments, the SRS resource set sent by the terminal may be a P-SRS resource set. The terminal may subsequently use the P-SRS resource set of the same time slot or an adjacent time slot to configure the SRS resource set currently used for DWS without sending an AP-SRS resource set.

[0169] In some embodiments, the SRS resource set sent by the terminal may be an SP-SRS resource set. The SRS resource set currently used for DWS may be configured using the SP-SRS resource set of the same time slot or an adjacent time slot, without sending the AP-SRS resource set.

[0170] In some embodiments, the first information is used to instruct the terminal to send the first PUSCH, the second PUSCH, and the SRS resource set in the same time slot.

[0171] In some embodiments, the transmission of the first PUSCH and the second PUSCH can be used for DWS decision-making. The network device can make a DWS decision based on the first PUSCH and the second PUSCH. For example, the signal to interference plus noise ratio (SINR) under different waveforms can be obtained by performing uplink channel estimation on the first PUSCH and the second PUSCH, that is, transmission quality reference information under different waveforms can be obtained. The network device can make a DWS decision based on the transmission quality reference information under different waveforms.

[0172] In some embodiments, the first information may be downlink control information (DCI), but is not limited thereto.

[0173] In some embodiments, the first PUSCH can be scheduled to be sent using the first waveform in the same time slot via DCI (e.g., DWS=0), while triggering the sending of SRS resources. The second PUSCH can be continuously scheduled to be sent using the second waveform via DCI (e.g., DWS=1).

[0174] In some embodiments, a DCI, such as DWS=0, schedules the transmission of a first PUSCH using a first waveform and triggers the transmission of SRS resources. In adjacent time slots, a DCI, such as DWS=1, schedules the transmission of a second PUSCH using a second waveform and triggers the transmission of SRS resources.

[0175] In some embodiments, the name of the first information is not limited, and it can be, for example, "indication information", "scheduling information", etc.

[0176] In some embodiments, the names of information, etc. are not limited to the names described in the embodiments, and terms such as "information", "message", "signal", "signaling", "report", "configuration", "indication", "instruction", "command", "channel", "parameter", "domain", "field", "symbol", "symbol", "codeword", "codebook", "codeword", "codepoint", "bit", "data", "program", etc. can be used interchangeably.

[0177] Step S2102 , the terminal 101 sends second information to the network device 102 .

[0178] In some embodiments, the network device 102 receives the second information sent by the terminal.

[0179] In some embodiments, the second information is used to indicate the number of SRS resource set ports supported by the terminal.

[0180] In some embodiments, the second information may be used to represent one or more terminal capabilities, where the terminal capabilities include the number of SRS resource set ports supported by the terminal. When the second information is used to represent multiple terminal capabilities, in addition to the number of SRS resource set ports supported by the terminal, it may also include, for example, frequency bands and carrier aggregation combinations supported by the terminal.

[0181] In some embodiments, the name of the second information is not limited, and the second information may also be called terminal capability information, etc.

[0182] Step S2103 : The terminal 101 sends an SRS resource set, a first PUSCH, and a second PUSCH to the network device 102 .

[0183] In some embodiments, the network device 102 receives the SRS resource set, the first PUSCH, and the second PUSCH sent by the terminal 101 .

[0184] In some embodiments, the SRS resource set is used by a network device to obtain uplink channel state information (CSI).

[0185] In some embodiments, the network device switches ranks based on CSI.

[0186] In some embodiments, the first PUSCH and the second PUSCH are used to schedule the uplink transmission waveform. For example, if the SINR of the first PUSCH is greater than the SINR of the second PUSCH through uplink channel estimation based on the first PUSCH and the second PUSCH, the first waveform is switched to the second waveform. The first waveform can be understood as the currently used waveform, and the second waveform can be understood as the target waveform after the switch.

[0187] In some embodiments, the terminal may send an SRS resource set before sending the first PUSCH and the second PUSCH in the same time slot. For example, the terminal may send an SRS resource set before sending the first PUSCH and the second PUSCH in the same time slot.

[0188] In some embodiments, in the same time slot, the terminal may send an SRS resource set between sending the first PUSCH and sending the second PUSCH. For example, the terminal first sends the first PUSCH, then sends the SRS resource set, and finally sends the second PUSCH.

[0189] In some embodiments, in the same time slot, the terminal may send the SRS resource set after sending the first PUSCH and the second PUSCH. For example, the terminal first sends the first PUSCH and the second PUSCH, and then sends the SRS resource set.

[0190] In some embodiments, a terminal may transmit a first PUSCH and, in an adjacent time slot, a second PUSCH and an SRS resource set. In the adjacent time slots, the terminal may transmit the second PUSCH first and then the SRS resource set. Alternatively, the terminal may transmit the SRS resource set first and then the second PUSCH.

[0191] In some embodiments, the terminal may transmit a first PUSCH and an SRS resource set, and transmit a second PUSCH in an adjacent time slot. Alternatively, the terminal may transmit the SRS resource set first and then the first PUSCH.

[0192] In some embodiments, the terminal does not send other SRS resource sets in the time domain transmission symbols occupied by the SRS resource set used for DWS.

[0193] In step S2104 , the network device 102 makes a DWS decision based on the SRS resource set, the first PUSCH, and the second PUSCH.

[0194] In some embodiments, the network device 102 can switch the rank based on the SRS resource set and switch the uplink transmission waveform based on the first PUSCH and the second PUSCH. The network device performs DWS including rank switching based on the SRS resource set, the first PUSCH and the second PUSCH, to achieve synchronous switching of rank while switching the waveform.

[0195] In some embodiments, the terminal can switch the uplink transmission waveform and rank based on the DWS of the network device to improve communication efficiency.

[0196] The communication method involved in the embodiment of the present disclosure may include at least one of steps S2101 to S2104. For example, step S2101 may be implemented as an independent embodiment. Steps S2101 and S2103 may be implemented as independent embodiments.

[0322] The present disclosure also provides a communication method as follows:

[0323] In some embodiments, an SRS resource set with a function (usage) of "DWS" is defined, each SRS resource set includes one or more multi-port SRS resources, or an SRS resource set based on "codebook" or "antenna switching" is reused, where SRS is used to obtain uplink (UL) CSI.

[0324] In some embodiments, for PUSCH transmissions configured as "codebook", SRS resource configurations with configuration functions as "DWS" or "codebook" or "antenna switching" may be supported for DWS;

[0325] In some embodiments, for PUSCH transmissions configured as "non-codebook", SRS resource configurations with the configuration function "DWS" or "codebook" or "antenna switching" may be supported for DWS;

[0326] In some embodiments, the number of supported SRS ports may be reported based on terminal capabilities;

[0327] In some embodiments, enhanced transmission: implemented through DCI scheduling method

[0328] In some embodiments, it is achieved through continuous DCI+SRS: in the same time slot, DCI scheduling is used, such as DWS=0, and PUSCH1 is sent using waveform 1, while triggering SRS transmission for DWS. At the same time, DCI, such as DWS=1, is continuously scheduled to send PUSCH2 using waveform 2.

[0329] In some embodiments, waveform 1 may be a first waveform, waveform 2 may be a second waveform, PUSCH 1 may be a first PUSCH, and PUSCH 2 may be a second PUSCH.

[0330] In some embodiments, PUSCH1+SRS+PUSCH2 or SRS+PUSCH1+PUSCH2 are sent in the same time slot, and PUSCH1 / PUSCH2 scheduling corresponds to RANK-1 transmission.

[0331] In some embodiments, due to scheduling restrictions, it is achieved by continuous scheduling of DCI+SRS. Through DCI scheduling, such as DWS=0, PUSCH1 is sent using waveform 1, and the SRS transmission for DWS is triggered at the same time. In adjacent time slots, through DCI, such as DWS=1, continuous scheduling is used to send PUSCH2 using waveform 2, and the SRS transmission for DWS is triggered at the same time.

[0332] In some embodiments, transmission: PUSCH1+SRS / SRS+PUSCH1 and PUSCH2+SRS / SRS+PUSCH2 are respectively transmitted in different time slots, and PUSCH1 / PUSCH2 scheduling corresponds to rank 1 transmission;

[0333] In some embodiments, the SRS is configured as an aperiodic SRS resource set;

[0334] In some embodiments, SRS transmission requires:

[0335] On the same carrier, the SRS used for DWS does not overlap with other SRS in time domain configuration;

[0336] The CSI estimation information and different waveform information are combined to realize the coordinated dynamic switching of waveform and rank.

[0337] 1) PUSCH back-to-back transmissions scheduled by DCI do not perform rank selection and are only used for waveform selection;

[0338] 2) CSI estimation using the transmitted SRS;

[0339] The waveform selection + rank selection is performed by combining the above 1) + 2) for the actual DWS including rank switching, that is, the rank is switched synchronously while the waveform is switched;

[0340] In some embodiments, the scheduler supports rank restrictions:

[0341] The current rank scheduling limit for DFT-S-OFDM is still 1;

[0342] In the future, DFT-S-OFDM may also support transmission with RANK>1, so there is no restriction.

[0343] The embodiments of the present disclosure further provide an apparatus for implementing any of the above methods. For example, an apparatus is provided, comprising units or modules for implementing each step performed by a terminal in any of the above methods.
