Description

Technical Field

[0001] The present application relates to the field of communication technology, and in particular to a power headroom reporting method, device, terminal and network equipment. Background Art

[0002] At present, the existing technology supports the dynamic waveform switching of the physical uplink shared channel (PUSCH). The base station can dynamically indicate the scheduled PUSCH to use the cyclic prefix orthogonal frequency division multiplexing (CP-OFDM) or discrete Fourier transform spread orthogonal frequency division multiplexing (DFT-S-OFDM) waveform through the downlink control information (DCI). In order to assist the base station in determining the appropriate waveform, the UE needs to report the power headroom (PH) calculated based on the reference PUSCH (also called the hypothetical PUSCH).

[0003] The existing triggering mechanism of Power Headroom Report (PHR) includes: triggering based on a periodic timer, or triggering when the path loss change exceeds a threshold. However, the existing scheme does not match the scenario requirements of PUSCH waveform switching. For example, if the period is long, the PH cannot be reported in time based on the method based on the periodic timer; if the period is short, always reporting the PH of two waveforms will cause high overhead and reduce resource utilization efficiency. If the PH calculated based on the assumed / reference PUSCH is reported only when the PUSCH waveform changes, it cannot be used for base station waveform decision because it occurs after the base station waveform switching decision.

[0004] From the above analysis, it can be seen that the existing PHR triggering mechanism has the problem of untimely reporting and may also cause excessive power headroom reporting overhead. Summary of the invention

[0151] The following will be combined with the drawings in the embodiments of the present application to clearly and completely describe the technical solutions in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of this application.

[0152] In the embodiments of the present application, the term "and / or" describes the association relationship of the associated objects, indicating that three relationships may exist. For example, A and / or B may represent: A exists alone, A and B exist at the same time, and B exists alone. The character " / " generally indicates that the associated objects before and after are in an "or" relationship.

[0153] In the embodiments of the present application, the term "plurality" refers to two or more than two, and other quantifiers are similar.

[0154] The terminal device involved in the embodiment of the present application may be a device that provides voice and / or data connectivity to a user, a handheld device with a wireless connection function, or other processing devices connected to a wireless modem. In different systems, the name of the terminal device may also be different. For example, in a 5G system, the terminal device may be called a user equipment (UE). The wireless terminal device can communicate with one or more core networks (CN) via a radio access network (RAN). The wireless terminal device can be a mobile terminal device, such as a mobile phone (or a "cellular" phone) and a computer with a mobile terminal device. For example, it can be a portable, pocket-sized, handheld, computer-built-in or vehicle-mounted mobile device that exchanges language and / or data with a wireless access network. For example, personal communication service (PCS) phones, cordless phones, session initiation protocol (SIP) phones, wireless local loop (WLL) stations, personal digital assistants (PDA) and other devices. The wireless terminal device may also be referred to as a system, a subscriber unit, a subscriber station, a mobile station, a mobile station, a remote station, an access point, a remote terminal device, an access terminal device, a user terminal device, a user agent, and a user device, but is not limited in the embodiments of the present application.

[0155] The network device involved in the embodiment of the present application may be a base station, which may include multiple cells providing services for the terminal. Depending on the specific application scenario, the base station may also be called an access point, or may be a device in the access network that communicates with the wireless terminal device through one or more sectors on the air interface, or other names. The network device may be used to interchange received air frames with Internet Protocol (IP) packets, and serve as a router between the wireless terminal device and the rest of the access network, wherein the rest of the access network may include an Internet Protocol (IP) communication network. The network device may also coordinate the attribute management of the air interface. For example, the network device involved in the embodiments of the present application may be a network device (Base Transceiver Station, BTS) in the Global System for Mobile communications (Global System for Mobile communications, GSM) or Code Division Multiple Access (Code Division Multiple Access, CDMA), or a network device (NodeB) in Wide-band Code Division Multiple Access (WCDMA), or an evolutionary network device (evolutional Node B, eNB or e-NodeB) in the long term evolution (long term evolution, LTE) system, a 5G base station (gNB) in the 5G network architecture (next generation system), or a home evolved Node B (Home evolved Node B, HeNB), a relay node, a home base station (femto), a pico base station (pico), etc., which is not limited in the embodiments of the present application. In some network structures, the network device may include a centralized unit (CU) node and a distributed unit (DU) node, and the centralized unit and the distributed unit may also be arranged geographically separately.

[0156] Network devices and terminal devices can each use one or more antennas for multiple-input multiple-output (MIMO) transmission. MIMO transmission can be single-user MIMO (SU-MIMO) or multi-user MIMO (MU-MIMO). Depending on the form and number of antenna combinations, MIMO transmission can be 2D-MIMO, 3D-MIMO, FD-MIMO or massive-MIMO, or it can be diversity transmission, precoded transmission or beamforming transmission, etc.

[0157] The following first introduces the contents involved in the solution provided in the embodiment of the present application.

[0158] In order to help the base station determine the appropriate waveform, the enhancement of power headroom reporting PHR is currently being discussed. Specifically, the UE reports the PH calculated based on the assumed / reference PUSCH, which is different from the current actual transmitted PUSCH waveform. However, there is no conclusion on the reporting trigger conditions for the PH calculated based on the assumed / reference PUSCH transmission. Some discussions tend to use the existing PHR trigger mechanism. When the PHR is triggered, the UE reports the actual PUSCH PH and the assumed / reference PUSCH PH at the same time. Other opinions tend to report the PH calculated based on the assumed / reference PUSCH when the PUSCH waveform changes.

[0159] However, the existing PHR trigger mechanism is mainly based on periodic timers or path loss changes exceeding thresholds, which does not match the scenario requirements of PUSCH waveform switching, and there are problems such as untimely reporting or excessive power headroom reporting overhead. If the PH calculated based on the assumption / reference PUSCH is reported only when the PUSCH waveform changes, it cannot be used for base station waveform decision-making because it occurs after the base station waveform switching decision.

[0160] Therefore, the currently proposed PHR triggering mechanism cannot provide the base station with timely PH information and may also lead to the problem of excessive PHR overhead.

[0161] Specifically, the embodiments of the present application provide a power headroom reporting method, apparatus, terminal and network equipment to solve the problems of untimely reporting and excessive power headroom reporting overhead in the existing power headroom reporting triggering mechanism.

[0162] See also Figure 1 The embodiment of the present application provides a power headroom reporting method, which is applied to a terminal and may specifically include the following steps:

[0163] Step 101, according to the first information, sending a power headroom calculated based on a first physical uplink shared channel PUSCH transmission to a network device, the waveform types of the first PUSCH transmission and the second PUSCH transmission are different, and the second PUSCH transmission is a PUSCH actually transmitted by the carrier;

[0164] The first information includes at least one of the following:

[0165] The on state of the dynamic waveform switching corresponding to the carrier;

[0166] a power headroom corresponding to the first PUSCH transmission;

[0167] a power headroom corresponding to the second PUSCH transmission;

[0168] a waveform type of the second PUSCH transmission;

[0169] a type of the second PUSCH transmission;

[0170] a resource allocation method for the second PUSCH transmission;

[0171] The modulation mode of the second PUSCH transmission.

[0172] It should be noted that, in the case of multiple carriers, this step is performed independently based on each component carrier (CC), that is, the first information of the CC is determined for each CC respectively and the power margin calculated based on the first physical uplink shared channel PUSCH transmission on the CC is sent to the network device according to the first information of the CC.

[0173] Optionally, the waveform type of the second PUSCH transmission includes CP-OFDM or DFT-S-OFDM.

[0174] It should be noted that the first PUSCH transmission is also called a hypothetical PUSCH transmission or a reference PUSCH transmission, which is different from the waveform of the actual PUSCH transmission. For example, if the waveform of the second PUSCH transmission actually transmitted is CP-OFDM, the waveform of the first PUSCH transmission is DFT-S-OFDM; if the waveform of the second PUSCH transmission actually transmitted is DFT-S-OFDM, the waveform of the first PUSCH transmission is CP-OFDM. In the above embodiment, it can ensure that the power margin corresponding to the first PUSCH transmission that is different from the actual PUSCH transmission waveform is reported in a timely manner, and can reduce unnecessary reporting overhead.

[0175] In one embodiment, in the above step 101, sending the power headroom calculated based on the first physical uplink shared channel PUSCH transmission to the network device according to the first information includes:

[0176] Determining whether a trigger condition is met according to the first information;

[0177] When it is determined that the trigger condition is met, sending a power headroom calculated based on the first PUSCH transmission to the network device;

[0178] The trigger condition includes at least one of the following:

[0179] The carrier used for the second PUSCH transmission has enabled dynamic waveform switching;

[0180] The power headroom corresponding to the first PUSCH transmission and the power headroom corresponding to the second PUSCH transmission meet a preset condition;

[0181] The second PUSCH transmission does not belong to the target PUSCH transmission.

[0182] Optionally, when the trigger condition is met, the UE may report only the PH calculated based on the assumed / reference PUSCH transmission, or may report both the PH calculated based on the actual PUSCH transmission and the PH calculated based on the assumed / reference PUSCH transmission, which can be adjusted according to actual needs.

[0183] This embodiment is described below by means of the following examples.

[0184] Example 1: The trigger condition only includes that the carrier used for the second PUSCH transmission has enabled dynamic waveform switching.

[0185] That is, when it is determined that the carrier used for the second PUSCH transmission has enabled dynamic waveform switching, the power headroom calculated based on the first PUSCH transmission is sent to the network device.

[0186] In the above example 1, since the purpose of reporting the PH calculated based on the assumed / reference PUSCH is to assist the base station in determining the waveform of the PUSCH, if the carrier used for the second PUSCH transmission does not have DWS enabled, reporting the PH calculated based on the second PUSCH transmission is meaningless and will result in increased overhead. Therefore, when it is determined that the carrier used for the second PUSCH transmission has dynamic waveform switching enabled, the power headroom calculated based on the first PUSCH transmission is sent to the network device, which can avoid unnecessary reporting overhead.

[0187] It should be noted that, in addition to the trigger conditions shown in Example 1, additional trigger conditions may also be specified, and for each carrier, the PH calculated based on the assumed / reference PUSCH transmission is reported only when the additional trigger conditions are also met. Similarly, additional non-reporting conditions may also be specified, and for each carrier, if the additional non-reporting conditions are met, the PH calculated based on the assumed / reference PUSCH transmission is not reported.

[0188] Example 2: The triggering conditions include: the carrier used for the second PUSCH transmission has enabled dynamic waveform switching, and the power margin corresponding to the first PUSCH transmission and the power margin corresponding to the second PUSCH transmission meet preset conditions.

[0189] In this example 2, when both conditions are met that the carrier used for the second PUSCH transmission has enabled dynamic waveform switching, and that the power margin corresponding to the first PUSCH transmission and the power margin corresponding to the second PUSCH transmission meet preset conditions, the power margin calculated based on the first PUSCH transmission is sent to the network device.

[0190] It should be noted that this Example 2 does not exclude the provision of additional trigger conditions, that is, in addition to satisfying the two trigger conditions included in Example 2, it is not limited to satisfying additional other trigger conditions before the PH calculated based on the assumed / reference PUSCH transmission can be reported. Similarly, additional non-reporting conditions may also be specified. For each carrier, if the additional non-reporting conditions are met, the PH calculated based on the assumed / reference PUSCH transmission is not reported.

[0191] Example 3: The trigger conditions include: the carrier used for the second PUSCH transmission has enabled dynamic waveform switching, the power margin corresponding to the first PUSCH transmission and the power margin corresponding to the second PUSCH transmission meet preset conditions, and the second PUSCH transmission does not belong to the target PUSCH transmission.

[0192] In this example three, when the following three conditions are met at the same time: the carrier used for the second PUSCH transmission has enabled dynamic waveform switching, the power margin corresponding to the first PUSCH transmission and the power margin corresponding to the second PUSCH transmission meet the preset conditions, and the second PUSCH transmission does not belong to the target PUSCH transmission, the power margin calculated based on the first PUSCH transmission is sent to the network device.

[0193] It should be noted that this example 3 does not exclude the provision of additional trigger conditions, that is, in addition to satisfying the three trigger conditions included in this example 3, it is not limited to that additional other trigger conditions need to be satisfied before the PH calculated based on the assumed / reference PUSCH transmission can be reported. Similarly, additional non-reporting conditions may also be specified. For each carrier, if the additional non-reporting conditions are met, the PH calculated based on the assumed / reference PUSCH transmission is not reported.

[0194] In an optional embodiment, the preset condition includes one of the following:

[0195] Condition 1: The waveform type of the second PUSCH transmission is cyclic prefix orthogonal frequency division multiplexing CP-OFDM, and the power headroom corresponding to the second PUSCH transmission is less than or equal to the first threshold, and the power headroom corresponding to the first PUSCH transmission is greater than or equal to the second threshold;

[0196] In condition 1, if the waveform of the second PUSCH transmission actually transmitted by the carrier is CP-OFDM, the PH corresponding to the first PUSCH transmission is reported only when its corresponding PH is less than or equal to the first threshold and the PH corresponding to the first PUSCH transmission different from the waveform of the second PUSCH transmission is greater than or equal to the second threshold.

[0197] Condition 2: The waveform type of the second PUSCH transmission is cyclic prefix orthogonal frequency division multiplexing CP-OFDM, and the power margin corresponding to the second PUSCH transmission is less than the first threshold, and the power margin corresponding to the first PUSCH transmission is greater than or equal to the second threshold.

[0198] In condition 2, if the waveform of the second PUSCH transmission actually transmitted by the carrier is CP-OFDM, the PH corresponding to the first PUSCH transmission is reported only when its corresponding PH is less than the first threshold and the PH corresponding to the first PUSCH transmission different from the waveform of the second PUSCH transmission is greater than or equal to the second threshold.

[0199] Condition 3: The waveform type of the second PUSCH transmission is cyclic prefix orthogonal frequency division multiplexing CP-OFDM, and the power margin corresponding to the second PUSCH transmission is less than or equal to the first threshold, and the power margin corresponding to the first PUSCH transmission is greater than the second threshold.

[0200] In condition 3, if the waveform of the second PUSCH transmission actually transmitted by the carrier is CP-OFDM, the PH corresponding to the first PUSCH transmission is reported only when its corresponding PH is less than or equal to the first threshold and the PH corresponding to the first PUSCH transmission different from the waveform of the second PUSCH transmission is greater than the second threshold.

[0201] Condition 4: The waveform type of the second PUSCH transmission is cyclic prefix orthogonal frequency division multiplexing CP-OFDM, and the power margin corresponding to the second PUSCH transmission is less than the first threshold, and the power margin corresponding to the first PUSCH transmission is greater than the second threshold.

[0202] In condition 4, if the waveform of the second PUSCH transmission actually transmitted by the carrier is CP-OFDM, the PH corresponding to the first PUSCH transmission is reported only when its corresponding PH is less than the first threshold and the PH corresponding to the first PUSCH transmission different from the waveform of the second PUSCH transmission is greater than the second threshold.

[0203] Optionally, the first threshold and the second threshold in the above conditions 1 to 4 may be predefined or configured by the network side, and the first threshold and the second threshold may be the same or different.

[0204] For example, the first threshold and the second threshold can be predefined as 0, that is, when the power of the second PUSCH transmission using the CP-OFDM waveform is insufficient, but the first PUSCH transmission using the DFT-S-OFDM waveform has sufficient power, the power margin of the first PUSCH transmission is reported.

[0205] For another example, the first threshold and the second threshold are predefined different values, such as the first threshold is 0, and the second threshold is a value greater than 0, that is, when the power of the second PUSCH transmission using the CP-OFDM waveform is insufficient and the first PUSCH transmission using the DFT-S-OFDM waveform has a certain power margin, the power margin calculated based on the first PUSCH transmission is reported.

[0206] For another example, one or both of the first threshold and the second threshold are configured by the network side, such as the first threshold is fixed to 0, and the value of the second threshold is configured by the network side.

[0207] Condition 5: The waveform type of the second PUSCH transmission is discrete Fourier transform spread orthogonal frequency division multiplexing DFT-s-OFDM, and the power headroom corresponding to the second PUSCH transmission is greater than or equal to the third threshold, and the power headroom corresponding to the first PUSCH transmission is greater than or equal to the fourth threshold;

[0208] In condition 5, if the waveform corresponding to the second PUSCH transmission actually transmitted by the carrier is DFT-S-OFDM, the power margin calculated based on the first PUSCH transmission is reported only when the PH corresponding to the second PUSCH transmission is greater than or equal to the third threshold and the PH corresponding to the first PUSCH transmission different from the waveform of the second PUSCH transmission is greater than or equal to the fourth threshold.

[0209] Condition 6: The waveform type of the second PUSCH transmission is discrete Fourier transform extended orthogonal frequency division multiplexing DFT-s-OFDM, and the power margin corresponding to the second PUSCH transmission is greater than the third threshold, and the power margin corresponding to the first PUSCH transmission is greater than or equal to the fourth threshold.

[0210] In condition 6, if the waveform corresponding to the second PUSCH transmission actually transmitted by the carrier is DFT-S-OFDM, the power margin calculated based on the first PUSCH transmission is reported only when the PH corresponding to the second PUSCH transmission is greater than the third threshold and the PH corresponding to the first PUSCH transmission different from the waveform of the second PUSCH transmission is greater than or equal to the fourth threshold.

[0211] Condition 7: The waveform type of the second PUSCH transmission is discrete Fourier transform extended orthogonal frequency division multiplexing DFT-s-OFDM, and the power margin corresponding to the second PUSCH transmission is greater than or equal to the third threshold, and the power margin corresponding to the first PUSCH transmission is greater than the fourth threshold.

[0212] In condition 7, if the waveform corresponding to the second PUSCH transmission actually transmitted by the carrier is DFT-S-OFDM, the power margin calculated based on the first PUSCH transmission is reported only when the PH corresponding to the second PUSCH transmission is greater than or equal to the third threshold and the PH corresponding to the first PUSCH transmission different from the waveform of the second PUSCH transmission is greater than the fourth threshold.

[0213] Condition 8: The waveform type of the second PUSCH transmission is discrete Fourier transform extended orthogonal frequency division multiplexing DFT-s-OFDM, and the power margin corresponding to the second PUSCH transmission is greater than the third threshold, and the power margin corresponding to the first PUSCH transmission is greater than the fourth threshold.

[0214] In condition 8, if the waveform corresponding to the second PUSCH transmission actually transmitted by the carrier is DFT-S-OFDM, the power margin calculated based on the first PUSCH transmission is reported only when the PH corresponding to the second PUSCH transmission is greater than the third threshold and the PH corresponding to the first PUSCH transmission different from the waveform of the second PUSCH transmission is greater than the fourth threshold.

[0215] Optionally, the third threshold and the fourth threshold in the above conditions 4 to 8 are predefined, and the third threshold and the fourth threshold may be the same or different. For example, the third threshold and the fourth threshold are unified as 0, that is, when the PH corresponding to the two waveforms are both greater than 0, they are reported. For example, the third threshold is a value greater than 0, and the fourth threshold is 0. For example, the third threshold and the fourth threshold are both greater than 0 and the third threshold is greater than the fourth threshold.

[0216] Optionally, one or both of the third threshold and the fourth threshold are configured by the network side, and the third threshold and the fourth threshold may be the same or different. For example, the fourth threshold is fixed to 0, and the value of the third threshold is configured by the network side.

[0217] It should be pointed out that the above conditions 1 to 8 are judged based on the waveform of the current actual PUSCH transmission, that is, the above conditions 1 to 8 are related to the waveform of the current actual PUSCH transmission, and the corresponding trigger conditions are different if the waveform of the current actual PUSCH transmission is different.

[0218] The above conditions 1 to 8 are for possible scenarios of PUSCH waveform switching, and the PH values ​​of different waveforms are considered for judgment, so that timely reporting can be performed on potential waveform switching conditions. At the same time, no reporting is performed under conditions where there is a high probability that switching is not required, so as to reduce unnecessary reporting overhead.

[0219] Condition 9: the power headroom corresponding to the second PUSCH transmission is less than or equal to the fifth threshold, and the power headroom corresponding to the first PUSCH transmission is greater than or equal to the sixth threshold.

[0220] Condition 10: the power headroom corresponding to the second PUSCH transmission is less than the fifth threshold, and the power headroom corresponding to the first PUSCH transmission is greater than or equal to the sixth threshold.

[0221] The fifth threshold and the sixth threshold here may be predefined or configured by the network side, and the fifth threshold and the sixth threshold may be the same or different.

[0222] Condition 11: The power headroom corresponding to the second PUSCH transmission is less than or equal to the fifth threshold, and the power headroom corresponding to the first PUSCH transmission is greater than the sixth threshold.

[0223] Condition 12: the power headroom corresponding to the second PUSCH transmission is less than the fifth threshold, and the power headroom corresponding to the first PUSCH transmission is greater than the sixth threshold.

[0224] Optionally, the fifth threshold and the sixth threshold in the above conditions 9 to 12 are predefined, and the fifth threshold and the sixth threshold may be the same or different.

[0225] Optionally, one or all of the fifth threshold and the sixth threshold in the above conditions 9 to 12 are configured by the network side, and the fifth threshold and the sixth threshold may be the same or different.

[0226] In conditions 9 to 12, considering that the actual PUSCH transmission adopts insufficient power using the current waveform, if it is replaced with another waveform, insufficient power will not occur, so the fifth threshold and the sixth threshold can be assumed to be greater than or equal to 0.

[0227] Condition 13: The power headroom corresponding to the second PUSCH transmission is greater than or equal to the seventh threshold, and the power headroom corresponding to the first PUSCH transmission is greater than or equal to the eighth threshold.

[0228] Condition 14: the power headroom corresponding to the second PUSCH transmission is greater than the seventh threshold, and the power headroom corresponding to the first PUSCH transmission is greater than or equal to the eighth threshold.

[0229] Condition 15: The power headroom corresponding to the second PUSCH transmission is greater than or equal to the seventh threshold, and the power headroom corresponding to the first PUSCH transmission is greater than the eighth threshold.

[0230] Condition 16: The power headroom corresponding to the second PUSCH transmission is greater than the seventh threshold, and the power headroom corresponding to the first PUSCH transmission is greater than the eighth threshold.

[0231] Optionally, the seventh threshold and the eighth threshold in the above conditions 12 to 16 are predefined, and the seventh threshold and the eighth threshold may be the same or different.

[0232] Optionally, one or all of the seventh threshold and the eighth threshold in the above conditions 12 to 16 are configured by the network side, and the seventh threshold and the eighth threshold may be the same or different.

[0233] It should be noted that the above conditions 9 to 16 have nothing to do with the waveform of the current actual PUSCH transmission.

[0234] In an optional embodiment, the target PUSCH transmission includes:

[0235] PUSCH transmission during random access;

[0236] Configure granted PUSCH transmission;

[0237] PUSCH transmission using resource allocation type 0;

[0238] PUSCH transmission using non-contiguous frequency domain resource allocation;

[0239] PUSCH transmission adopts PI / 2 binary phase shift keying.

[0240] Specifically, considering that the calculation parameters of the PUSCH power control in the random access process and other PUSCHs may be different, when the second target PUSCH transmission belongs to the PUSCH transmission in the random access process, the power headroom reporting of the first PUSCH transmission is not triggered. The PUSCH transmission in the random access process may include only the initial transmission of the PUSCH, or include the initial transmission and retransmission of the PUSCH.

[0241] Specifically, since the calculation parameters of power control of the PUSCH transmission of the configured grant (Configured Grant, CG) and the PUSCH transmission of the dynamic scheduling may also be different, when the second target PUSCH transmission belongs to the PUSCH transmission of the configured grant, the power headroom reporting of the first PUSCH transmission is not triggered. Among them, the PUSCH of the configured grant may include only the initial transmission of the configured grant, or include the initial transmission and retransmission of the configured grant.

[0242] Specifically, since resource allocation type 0 (RA type 0) is only applicable to CP-OFDM waveform but not to DFT-S-OFDM, when the second target PUSCH transmission is a PUSCH transmission using resource allocation type 0, the power headroom reporting of the first PUSCH transmission is not triggered.

[0243] Specifically, since non-continuous resource allocation is only applicable to CP-OFDM waveform but not to DFT-S-OFDM, when the second target PUSCH transmission is a PUSCH transmission using non-continuous resource allocation, power headroom reporting of the first PUSCH transmission is not triggered.

[0244] Specifically, since PI / 2BPSK is only applicable to DFT-S-OFDM waveform but not to CP-OFDM, when the second target PUSCH transmission is a PUSCH transmission using PI / 2BPSK modulation, the power headroom reporting of the first PUSCH transmission is not triggered.

[0245] It should be noted that PI / 2 Binary Phase Shift Keying (π / 2-BPSK) is a modulation method. π / 2-BPSK means that the phase of the BPSK modulated signal is shifted by π / 2 when the sequence has odd bits, and the phase of the even bits of the sequence is the same as that of the BPSK modulated signal. That is, π / 2-BPSK defines four phases to represent 0 and 1.

[0246] Optionally, the target PUSCH transmission is not limited to the above five types, and may also include other PUSCH transmissions except the above five types.

[0247] In the above embodiment, when the second PUSCH transmission is the target PUSCH transmission, another waveform is not applicable. Even if the PH calculated based on the first PUSCH transmission is reported, the network side cannot make a waveform decision based on the reporting result. Therefore, when the second PUSCH transmission is the target PUSCH transmission, the PH calculated based on the first PUSCH transmission is not reported, which can avoid unnecessary reporting overhead.

[0248] In an optional embodiment, determining, according to the first information, that a carrier used for second PUSCH transmission has enabled dynamic waveform switching includes:

[0249] If any DCI format corresponding to any uplink bandwidth part in the carrier used for the second PUSCH transmission has dynamic waveform switching enabled, it is determined that the carrier used for the second PUSCH transmission has dynamic waveform switching enabled.

[0250] For example, it is assumed that the UE is configured with two carriers, CC1 and CC2. CC1 is configured with two uplink BWPs, denoted as BWP 1,1 and BWP 1,2 ; CC2 is configured with 2 uplink BWPs, denoted as BWP 2,1 and BWP 2,2 .BWP 1,1 and BWP 2,1 DWS is enabled for DCI format 0_1 ​​and disabled for DCI format 0_2; BWP 1,2 and BWP 2,2 DWS is not enabled for any DCI format in the protocol. If the protocol stipulates that DWS is enabled for any DCI format of any UL BWP, it is determined that DWS is enabled for the carrier. 1,1 and BWP in CC2 2,1 DWS is enabled for both DCI formats 0_1, so it is determined that DWS is enabled for both CC1 and CC2. It should be noted that since the assumed / reference PUSCH transmission (i.e., the first PUSCH transmission) is a PUSCH transmission with a waveform different from the current actual PUSCH transmission (i.e., the second PUSCH transmission), if there is no actual PUSCH transmission for a carrier, the UE does not need to calculate and report the PH corresponding to the assumed / reference PUSCH transmission. For example, if both CC1 and CC2 need to report PH, but there is PUSCH transmission on CC1 and no PUSCH transmission on CC2, the UE only reports the PH calculated based on the assumed / reference PUSCH transmission for CC1, and does not report the PH calculated based on the assumed / reference PUSCH transmission for CC2.

[0251] In an optional embodiment, determining, according to the first information, that a carrier used for second PUSCH transmission has enabled dynamic waveform switching includes:

[0252] If any DCI format corresponding to the activated uplink bandwidth part in the carrier used for the second PUSCH transmission has dynamic waveform switching enabled, it is determined that the carrier used for the second PUSCH transmission has dynamic waveform switching enabled.

[0253] For example, it is assumed that the UE is configured with two carriers, CC1 and CC2. CC1 is configured with two uplink BWPs, denoted as BWP 1,1 and BWP 1,2 ; CC2 is configured with 2 uplink BWPs, denoted as BWP 2,1 and BWP 2,2 .BWP 1,1 and BWP 2,1 Enable DWS for DCI format 0_1 ​​and disable DWS for DCI format 0_2; BWP 1,2 and BWP 2,2 If the protocol stipulates that any DCI format that currently activates UL BWP in the carrier used for the second PUSCH transmission has DWS enabled, it is determined that the carrier has DWS enabled. Then, for CC1, if the activated BWP is BWP 1,1 , it is considered that CC1 has turned on DWS; if BWP is activated 1,2 , it is considered that CC1 does not have DWS enabled. Similarly, for CC2, if the activated BWP is BWP 2,1 , it is considered that CC2 has DWS turned on; if BWP is activated 2,2 , it is considered that CC2 does not have DWS enabled.

[0254] See also Figure 2 The embodiment of the present application provides a power headroom reporting method, which is applied to a network device and includes the following steps:

[0255] Step 201, receiving a power headroom calculated based on a first PUSCH transmission sent by a terminal, wherein the waveform types of the first PUSCH transmission and the second PUSCH transmission are different, and the second PUSCH transmission is a PUSCH actually transmitted by a carrier;

[0256] The power headroom calculated based on the first PUSCH transmission is sent by the terminal according to first information, and the first information includes at least one of the following:

[0257] The on state of the dynamic waveform switching corresponding to the carrier;

[0258] a power headroom corresponding to the first PUSCH transmission;

[0259] a power headroom corresponding to the second PUSCH transmission;

[0260] a waveform type of the second PUSCH transmission;

[0261] a type of the second PUSCH transmission;

[0262] a resource allocation method for the second PUSCH transmission;

[0263] The modulation mode of the second PUSCH transmission.

[0264] It should be noted that, in the case of multiple carriers, this step is performed independently based on each component carrier (CC), that is, the first information of the CC is determined for each CC respectively, and according to the first information of the CC, the power headroom calculated based on the first physical uplink shared channel PUSCH transmission on the CC is sent to the network device. Optionally, the waveform type of the second PUSCH transmission includes CP-OFDM or DFT-S-OFDM.

[0265] It should be noted that the first PUSCH transmission is also called a hypothetical PUSCH transmission or a reference PUSCH transmission, which is different from the waveform of the actual PUSCH transmission. For example, if the waveform of the second PUSCH transmission actually transmitted is CP-OFDM, the waveform of the first PUSCH transmission is DFT-S-OFDM; if the waveform of the second PUSCH transmission actually transmitted is DFT-S-OFDM, the waveform of the first PUSCH transmission is CP-OFDM.

[0266] In the above embodiment, it is possible to ensure that the power headroom corresponding to the first PUSCH transmission waveform different from the actual PUSCH transmission waveform is reported in a timely manner, and unnecessary reporting overhead can be reduced.

[0267] In one embodiment, the power headroom calculated based on the first PUSCH transmission is sent by the terminal when determining that a trigger condition is met according to the first information;

[0268] The trigger condition includes at least one of the following:

[0269] The carrier used for the second PUSCH transmission has enabled dynamic waveform switching;

[0270] The power headroom corresponding to the first PUSCH transmission and the power headroom corresponding to the second PUSCH transmission meet a preset condition;

[0271] The second PUSCH transmission does not belong to the target PUSCH transmission.

[0272] Optionally, when the trigger condition is met, the UE may report only the PH calculated based on the assumed / reference PUSCH transmission, or may report both the PH calculated based on the actual PUSCH transmission and the PH calculated based on the assumed / reference PUSCH transmission, which can be adjusted according to actual needs.

[0273] The specific example is the same as the terminal side embodiment and will not be described again here to avoid repetition.

[0274] In an optional embodiment, the preset condition includes one of the following:

[0277] The power headroom corresponding to the second PUSCH transmission is less than or equal to a fifth threshold, and the power headroom corresponding to the first PUSCH transmission is greater than or equal to a sixth threshold;

[0278] The power headroom corresponding to the second PUSCH transmission is greater than or equal to a seventh threshold, and the power headroom corresponding to the first PUSCH transmission is greater than or equal to an eighth threshold.

[0279] Condition 1: The waveform type of the second PUSCH transmission is cyclic prefix orthogonal frequency division multiplexing CP-OFDM, and the power headroom corresponding to the second PUSCH transmission is less than or equal to the first threshold, and the power headroom corresponding to the first PUSCH transmission is greater than or equal to the second threshold;

[0280] In condition 1, if the waveform of the second PUSCH transmission actually transmitted by the carrier is CP-OFDM, the PH corresponding to the first PUSCH transmission is reported only when its corresponding PH is less than or equal to the first threshold and the PH corresponding to the first PUSCH transmission different from the waveform of the second PUSCH transmission is greater than or equal to the second threshold.

[0281] Condition 2: The waveform type of the second PUSCH transmission is cyclic prefix orthogonal frequency division multiplexing CP-OFDM, and the power margin corresponding to the second PUSCH transmission is less than the first threshold, and the power margin corresponding to the first PUSCH transmission is greater than or equal to the second threshold.

[0282] In condition 2, if the waveform of the second PUSCH transmission actually transmitted by the carrier is CP-OFDM, the PH corresponding to the first PUSCH transmission is reported only when its corresponding PH is less than the first threshold and the PH corresponding to the first PUSCH transmission different from the waveform of the second PUSCH transmission is greater than or equal to the second threshold.

[0283] Condition 3: The waveform type of the second PUSCH transmission is cyclic prefix orthogonal frequency division multiplexing CP-OFDM, and the power margin corresponding to the second PUSCH transmission is less than or equal to the first threshold, and the power margin corresponding to the first PUSCH transmission is greater than the second threshold.

[0284] In condition 3, if the waveform of the second PUSCH transmission actually transmitted by the carrier is CP-OFDM, the PH corresponding to the first PUSCH transmission is reported only when its corresponding PH is less than or equal to the first threshold and the PH corresponding to the first PUSCH transmission different from the waveform of the second PUSCH transmission is greater than the second threshold.

[0285] Condition 4: The waveform type of the second PUSCH transmission is cyclic prefix orthogonal frequency division multiplexing CP-OFDM, and the power margin corresponding to the second PUSCH transmission is less than the first threshold, and the power margin corresponding to the first PUSCH transmission is greater than the second threshold.

[0286] In condition 4, if the waveform of the second PUSCH transmission actually transmitted by the carrier is CP-OFDM, the PH corresponding to the first PUSCH transmission is reported only when its corresponding PH is less than the first threshold and the PH corresponding to the first PUSCH transmission different from the waveform of the second PUSCH transmission is greater than the second threshold.

[0287] Optionally, the first threshold and the second threshold in the above conditions 1 to 4 may be predefined or configured by the network side, and the first threshold and the second threshold may be the same or different.

[0288] For example, the first threshold and the second threshold can be predefined as 0, that is, when the power of the second PUSCH transmission using the CP-OFDM waveform is insufficient, but the first PUSCH transmission using the DFT-S-OFDM waveform has sufficient power, the power margin of the first PUSCH transmission is reported.

[0289] For another example, the first threshold and the second threshold are predefined different values, such as the first threshold is 0, and the second threshold is a value greater than 0, that is, when the power of the second PUSCH transmission using the CP-OFDM waveform is insufficient and the first PUSCH transmission using the DFT-S-OFDM waveform has a certain power margin, the power margin calculated based on the first PUSCH transmission is reported.

[0290] For another example, one or both of the first threshold and the second threshold are configured by the network side, such as the first threshold is fixed to 0, and the value of the second threshold is configured by the network side.

[0291] Condition 5: The waveform type of the second PUSCH transmission is discrete Fourier transform spread orthogonal frequency division multiplexing DFT-s-OFDM, and the power headroom corresponding to the second PUSCH transmission is greater than or equal to the third threshold, and the power headroom corresponding to the first PUSCH transmission is greater than or equal to the fourth threshold;

[0292] In condition 5, if the waveform corresponding to the second PUSCH transmission actually transmitted by the carrier is DFT-S-OFDM, the power margin calculated based on the first PUSCH transmission is reported only when the PH corresponding to the second PUSCH transmission is greater than or equal to the third threshold and the PH corresponding to the first PUSCH transmission different from the waveform of the second PUSCH transmission is greater than or equal to the fourth threshold.

[0294] In condition 6, if the waveform corresponding to the second PUSCH transmission actually transmitted by the carrier is DFT-S-OFDM, the power margin calculated based on the first PUSCH transmission is reported only when the PH corresponding to the second PUSCH transmission is greater than the third threshold and the PH corresponding to the first PUSCH transmission different from the waveform of the second PUSCH transmission is greater than or equal to the fourth threshold.

[0295] Condition 7: The waveform type of the second PUSCH transmission is discrete Fourier transform extended orthogonal frequency division multiplexing DFT-s-OFDM, and the power margin corresponding to the second PUSCH transmission is greater than or equal to the third threshold, and the power margin corresponding to the first PUSCH transmission is greater than the fourth threshold.

[0296] In condition 7, if the waveform corresponding to the second PUSCH transmission actually transmitted by the carrier is DFT-S-OFDM, the power margin calculated based on the first PUSCH transmission is reported only when the PH corresponding to the second PUSCH transmission is greater than or equal to the third threshold and the PH corresponding to the first PUSCH transmission different from the waveform of the second PUSCH transmission is greater than the fourth threshold.

[0297] Condition 8: The waveform type of the second PUSCH transmission is discrete Fourier transform extended orthogonal frequency division multiplexing DFT-s-OFDM, and the power margin corresponding to the second PUSCH transmission is greater than the third threshold, and the power margin corresponding to the first PUSCH transmission is greater than the fourth threshold.

[0298] In condition 8, if the waveform corresponding to the second PUSCH transmission actually transmitted by the carrier is DFT-S-OFDM, the power margin calculated based on the first PUSCH transmission is reported only when the PH corresponding to the second PUSCH transmission is greater than the third threshold and the PH corresponding to the first PUSCH transmission different from the waveform of the second PUSCH transmission is greater than the fourth threshold.

[0299] Optionally, the third threshold and the fourth threshold in the above conditions 4 to 8 are predefined, and the third threshold and the fourth threshold may be the same or different. For example, the third threshold and the fourth threshold are unified as 0, that is, when the PH corresponding to the two waveforms are both greater than 0, they are reported. For example, the third threshold is a value greater than 0, and the fourth threshold is 0. For example, the third threshold and the fourth threshold are both greater than 0 and the third threshold is greater than the fourth threshold.

[0300] Optionally, one or both of the third threshold and the fourth threshold are configured by the network side, and the third threshold and the fourth threshold may be the same or different. For example, the fourth threshold is fixed to 0, and the value of the third threshold is configured by the network side.

[0301] It should be pointed out that the above conditions 1 to 8 are judged based on the waveform of the current actual PUSCH transmission, that is, the above conditions 1 to 8 are related to the waveform of the current actual PUSCH transmission, and the corresponding trigger conditions are different if the waveform of the current actual PUSCH transmission is different.

[0302] The above conditions 1 to 8 are for possible scenarios of PUSCH waveform switching, and the PH values ​​of different waveforms are considered for judgment, so that timely reporting can be performed on potential waveform switching conditions. At the same time, no reporting is performed under conditions where there is a high probability that switching is not required, so as to reduce unnecessary reporting overhead.

[0303] Condition 9: the power headroom corresponding to the second PUSCH transmission is less than or equal to the fifth threshold, and the power headroom corresponding to the first PUSCH transmission is greater than or equal to the sixth threshold.

[0304] Condition 10: the power headroom corresponding to the second PUSCH transmission is less than the fifth threshold, and the power headroom corresponding to the first PUSCH transmission is greater than or equal to the sixth threshold.

[0305] The fifth threshold and the sixth threshold here may be predefined or configured by the network side, and the fifth threshold and the sixth threshold may be the same or different.

[0306] Condition 11: The power headroom corresponding to the second PUSCH transmission is less than or equal to the fifth threshold, and the power headroom corresponding to the first PUSCH transmission is greater than the sixth threshold.

[0307] Condition 12: the power headroom corresponding to the second PUSCH transmission is less than the fifth threshold, and the power headroom corresponding to the first PUSCH transmission is greater than the sixth threshold.

[0308] Optionally, the fifth threshold and the sixth threshold in the above conditions 9 to 12 are predefined, and the fifth threshold and the sixth threshold may be the same or different.

[0309] Optionally, one or all of the fifth threshold and the sixth threshold in the above conditions 9 to 12 are configured by the network side, and the fifth threshold and the sixth threshold may be the same or different.

[0310] In conditions 9 to 12, considering that the actual PUSCH transmission adopts insufficient power using the current waveform, if it is replaced with another waveform, insufficient power will not occur, so the fifth threshold and the sixth threshold can be assumed to be greater than or equal to 0.

[0311] Condition 13: The power headroom corresponding to the second PUSCH transmission is greater than or equal to the seventh threshold, and the power headroom corresponding to the first PUSCH transmission is greater than or equal to the eighth threshold.

[0312] Condition 14: the power headroom corresponding to the second PUSCH transmission is greater than the seventh threshold, and the power headroom corresponding to the first PUSCH transmission is greater than or equal to the eighth threshold.

[0313] Condition 15: The power headroom corresponding to the second PUSCH transmission is greater than or equal to the seventh threshold, and the power headroom corresponding to the first PUSCH transmission is greater than the eighth threshold.

[0314] Condition 16: The power headroom corresponding to the second PUSCH transmission is greater than the seventh threshold, and the power headroom corresponding to the first PUSCH transmission is greater than the eighth threshold.

[0315] Optionally, the seventh threshold and the eighth threshold in the above conditions 12 to 16 are predefined, and the seventh threshold and the eighth threshold may be the same or different.

[0316] Optionally, one or all of the seventh threshold and the eighth threshold in the above conditions 12 to 16 are configured by the network side, and the seventh threshold and the eighth threshold may be the same or different.

[0317] It should be noted that the above conditions 9 to 16 have nothing to do with the waveform of the current actual PUSCH transmission.

[0318] In an optional embodiment, the target PUSCH transmission includes:

[0319] PUSCH transmission during random access;

[0320] Configure granted PUSCH transmission;

[0321] PUSCH transmission using resource allocation type 0;

[0322] PUSCH transmission using non-contiguous frequency domain resource allocation;

[0323] PUSCH transmission adopts PI / 2 binary phase shift keying.

[0324] Specifically, considering that the calculation parameters of the PUSCH power control in the random access process and other PUSCHs may be different, when the second target PUSCH transmission belongs to the PUSCH transmission in the random access process, the power headroom reporting of the first PUSCH transmission is not triggered. The PUSCH transmission in the random access process may include only the initial transmission of the PUSCH, or include the initial transmission and retransmission of the PUSCH.

[0325] Specifically, since the calculation parameters of power control of the PUSCH transmission of the configured grant (Configured Grant, CG) and the PUSCH transmission of the dynamic scheduling may also be different, when the second target PUSCH transmission belongs to the PUSCH transmission of the configured grant, the power headroom reporting of the first PUSCH transmission is not triggered. Among them, the PUSCH of the configured grant may include only the initial transmission of the configured grant, or include the initial transmission and retransmission of the configured grant.

[0326] Specifically, since resource allocation type 0 (RA type 0) is only applicable to CP-OFDM waveform but not to DFT-S-OFDM, when the second target PUSCH transmission is a PUSCH transmission using resource allocation type 0, the power headroom reporting of the first PUSCH transmission is not triggered.

[0327] Specifically, since non-continuous resource allocation is only applicable to CP-OFDM waveform but not to DFT-S-OFDM, when the second target PUSCH transmission is a PUSCH transmission using non-continuous resource allocation, power headroom reporting of the first PUSCH transmission is not triggered.

[0328] Specifically, since PI / 2BPSK is only applicable to DFT-S-OFDM waveform but not to CP-OFDM, when the second target PUSCH transmission is a PUSCH transmission using PI / 2BPSK modulation, the power headroom reporting of the first PUSCH transmission is not triggered.

[0329] Optionally, the target PUSCH transmission is not limited to the above five types, and may also include other PUSCH transmissions except the above five types.

[0330] In the above embodiment, when the second PUSCH transmission is the target PUSCH transmission, another waveform is not applicable. Even if the PH calculated based on the first PUSCH transmission is reported, the network side cannot make a waveform decision based on the reporting result. Therefore, when the second PUSCH transmission is the target PUSCH transmission, the PH calculated based on the first PUSCH transmission is not reported, which can avoid unnecessary reporting overhead.
