[0147] Exemplary embodiments will now be described in detail, examples of which are illustrated in the accompanying drawings. When the following description relates to the drawings, unless otherwise indicated, the same numbers in different drawings denote the same or similar elements. The embodiments described in the following exemplary embodiments do not represent all embodiments consistent with this disclosure.
[0148] The terminal capability information determination method described in this disclosure can be applied to... Figure 1 The wireless communication system shown may include network device 110 and terminal 120. It is understood that... Figure 1The wireless communication system shown is for illustrative purposes only. A wireless communication system may also include other network devices, such as core network equipment, wireless relay equipment, and wireless backhaul equipment. Figure 1 Not shown in the diagram. This disclosure does not limit the number of network devices and terminals included in the wireless communication system.
[0149] It is further understood that the wireless communication system of this disclosure is a network providing wireless communication functionality. The wireless communication system can employ different communication technologies, such as Code Division Multiple Access (CDMA), Wideband Code Division Multiple Access (WCDMA), Time Division Multiple Access (TDMA), Frequency Division Multiple Access (FDMA), Orthogonal Frequency-Division Multiple Access (OFDMA), Single Carrier Frequency Division Multiple Access (SC-FDMA), and Carrier Sense Multiple Access with Collision Avoidance. Based on factors such as capacity, speed, and latency, networks can be categorized as 2G (Generation) networks, 3G networks, 4G networks, or future evolution networks, such as the 5th Generation Wireless Communication System (5G) network. 5G networks can also be referred to as New Radio (NR). For ease of description, this disclosure sometimes refers to the wireless communication network simply as a network.
[0150] Furthermore, the network device 110 involved in this disclosure can also be referred to as a wireless access network device. This wireless access network device can be: a base station, an evolved Node B (eNB), a home base station, an access point (AP) in a Wireless Fidelity (WIFI) system, a wireless relay node, a wireless backhaul node, a transmission point (TP), or a transmission and receiving point (TRP), etc. It can also be a gNB in an NR system, or a component or part of a base station. When it is a vehicle-to-everything (V2X) communication system, the network device can also be an in-vehicle device. It should be understood that the specific technology and specific device form used in the embodiments of this disclosure are not limited.
[0151] Furthermore, the terminal 120 involved in this disclosure can also be referred to as a terminal device, user equipment (UE), mobile station (MS), mobile terminal (MT), etc., which is a device that provides voice and / or data connectivity to a user. For example, the terminal can be a handheld device with wireless connectivity, an in-vehicle device, etc. Currently, some examples of terminals include: smartphones (Mobile Phones), pocket personal computers (PPCs), handheld computers, personal digital assistants (PDAs), laptops, tablets, wearable devices, or in-vehicle devices, etc. In addition, when it is a vehicle-to-everything (V2X) communication system, the terminal device can also be an in-vehicle device. It should be understood that the embodiments of this disclosure do not limit the specific technology or specific device form adopted by the terminal.
[0152] In this embodiment, network device 110 and terminal 120 can employ any feasible wireless communication technology to transmit data to each other. The transmission channel corresponding to network device 110 sending data or control information to terminal 120 is called the downlink channel (DL), and the transmission channel corresponding to terminal 120 sending data or control information to network device 110 is called the uplink channel (UL). It is understood that the network device involved in this embodiment can be a base station. Of course, the network device can also be any other possible network device, and the terminal can be any possible terminal; this disclosure does not limit the possibilities.
[0153] With the development of communication technology, in order to ensure coverage, uplink physical uplink shared channel (PUSCH) transmission is carried out to multiple transmission reception points (TRPs) of network equipment. Version (R) 17 introduced cooperative transmission under time-division multiplexing (TDM) technology. This method uses different transmission occupancy (TO) times in the time domain to send different repetitions of the same information on the PUSCH to different TRPs of the base station. This method has relatively low requirements for terminal capabilities, not requiring simultaneous beam transmission, but it has a larger transmission delay.
[0154] For uplink, the actual spatial characteristics of the PUSCH channels traversed by different TRPs may vary greatly. Therefore, it is assumed that the quasi-co-addressable QCL-D of PUSCH channels are different for different transmission directions.
[0155] In Release 18 (R18), the primary goal is to increase transmission reliability and throughput, and reduce transmission latency in multiple TRPs, by enabling simultaneous cooperative transmission to multiple TRPs via multiple antenna panels. However, this requires the terminal to have the capability to transmit multiple beams simultaneously. PUSCH transmission can be based on multi-panel / TRP transmission scheduled using a single physical downlink control channel (PDCCH), i.e., single-downlink control information (S-DCI), such as... Figure 2 As shown. PUSCH transmission can also be based on multi-panel / TRP transmission with different PDCCHs, i.e., multiple DCI (M-DCI) scheduling, such as... Figure 3 As shown.
[0156] In actual deployments, the links between transmission points may be relatively ideal backhaul links that support high throughput and very low backhaul latency, or they may be non-ideal backhaul links that use various Digital Subscribe Line (DSL), microwave, and relay methods. The non-coherent joint transmission (NC-JT) transmission scheme based on M-DCI was initially introduced mainly for non-ideal backhaul situations, but this scheme can also be used for ideal backhaul situations.
[0157] The current capability level definition of terminals in frequency range (FR)2 is defined according to different terminal types, including the power definition based on conducted power and the spatial power definition based on equivalent isotropically radiated power (EIRP), as shown in Table 1.
[0158] Table 1
[0159]
[0160] In New Radio (NR) technology, for terminals with dual power amplifiers (PAs) supporting carrier aggregation (CA) and dual connection (DC), the terminal's maximum transmit power is affected by the power class (PC) defined by the terminal. Taking a terminal with a defined power class of PC2 as an example, the terminal's PA capabilities can differ in different frequency bands. Table 2 shows examples of terminal power configurations.
[0161] Table 2
[0162] Terminal power level Network X-carrier power level Network Y-carrier power level Combination a 26dBm 23dBm 23dBm Combination b 26dBm 23dBm 26dBm Combination C 26dBm 26dBm 23dBm Combination d 26dBm 26dBm 26dBm
[0163] Here, X carrier and Y carrier represent different bands. Table 1 shows that if the terminal's power level is limited to 23 dBm in one frequency band and also limited to 23 dBm in another, the terminal's power level is limited to a maximum of 26 dBm. For example, in combinations b and c, when the terminal's power level is limited to 23 dBm in one frequency band and 26 dBm in another, the terminal's power level is limited to a maximum of 26 dBm due to relevant protocol specifications. However, in practice, the terminal's maximum transmit power can reach 27.8 dBm with an independent PA. Similarly, in combination d, the relevant protocol limits the maximum transmit power to 26 dBm, but in practice, the terminal's maximum transmit power can reach 29 dBm with an independent PA. In other words, the terminal's maximum transmit power is limited by the terminal power level specified in the protocol. In Release 17 (R17) regarding increasing the terminal power cap for CA / DC, for a band combination where one band supports power levels up to PC3 (23 dBm) and another band supports power levels up to PC2 (26 dBm), it can be assumed that the total power associated with the band combination is the sum of the individual power levels. R17 also supports higher-power terminals (High-power UEs, HPUEs) to better utilize the terminal's independent PA to achieve higher transmit power.
[0164] In the R18 Uplink MIMO enhancement, the aim is to achieve simultaneous uplink transmission for multiple TRPs using multiple panels, thereby further improving uplink system throughput and reliability. For terminals supporting STxMP transmission, different panels have independent PA structures. Currently, the sum of the transmit power of multiple panels is still limited by the maximum transmit power defined by the terminal's power class. Therefore, determining the maximum transmit power of each panel in a multi-panel configuration under STxMP transmission to achieve better transmission quality and coverage is a problem that needs to be solved.
[0165] Based on this, this disclosure provides a method for determining terminal capability information. By using the terminal capability information, it is determined that the sum of the transmission power of multiple antenna panels of the terminal under STxMP transmission is no longer limited to the maximum transmission power defined by the terminal's power level. Instead, the maximum transmission power of each antenna panel can reach full power transmission, thereby improving the transmission quality of uplink transmission and the system transmission throughput.
[0166] Figure 4 This is a flowchart illustrating a method for determining terminal capability information according to an exemplary embodiment, such as... Figure 4 As shown, the method for determining terminal capability information is executed by the terminal and includes the following steps.
[0167] In step S11, it is determined that the terminal supports uplink STxMP transmission.
[0168] In step S12, it is determined that the sum of the transmission power of different panels of the terminal under STxMP transmission is higher than the maximum transmission power determined based on the terminal's power level.
[0169] In step S13, the terminal's capability information is determined.
[0170] In step S14, capability information is sent to the network device.
[0171] In this embodiment of the disclosure, the capability information is used to indicate that the maximum transmit power of each panel in the multiple panels supports full-power transmission under STxMP transmission. The full power is determined based on the PA capability of each panel in the multiple panels or the power level of each panel.
[0172] In some embodiments, the capability information may be maximum transmit power capability information (HignPowerLimitSTxMP).
[0173] In some embodiments, the panel's PA capability is used to determine the panel's actual maximum transmit power, and the panel's power level is used to determine the panel's maximum transmit power based on the power level definition.
[0174] For example, if the terminal uses two panels for STxMP transmission, and the maximum transmit power of panel1 is defined as 26dBm based on the power level, and the maximum transmit power of panel2 is defined as 23dBm based on the power level, then the full power of panel1 and panel2 is 27.8dBm.
[0175] For example, if a terminal transmits STxMP data through two panels, and the actual transmission power of panel1, determined based on the PA capability, is 23dBm, and the actual transmission power of panel2, determined based on the PA capability, is also 23dBm, then the full power of panel1 and panel2 is 26dBm.
[0176] In some embodiments, when the terminal supports uplink STxMP transmission, the transmit power of panel1 is determined to be 23dBm based on the PA capability or power level of panel1, and the transmit power of panel2 is determined to be 26dBm based on the PA capability or power level of panel2. Therefore, the sum of the transmit powers of panel1 and panel2 can actually reach 27.8dBm. However, since the maximum transmit power defined by the terminal's power level is 26dBm, the sum of the maximum transmit powers of panel1 and panel2 can only reach a maximum of 26dBm, and cannot achieve the full-power transmit power of 27.8dBm. In this case, by determining through the terminal's capability information that the maximum transmit power of each panel in the multiple panels supports full-power transmission under STxMP transmission, the maximum transmit power of panel1 and panel2 can reach the full-power transmit power of 27.8dBm.
[0177] In this embodiment of the disclosure, when the terminal supports STxMP transmission, and the sum of the transmission power of different panels of the terminal under STxMP transmission is higher than the maximum transmission power determined based on the terminal's power level, the terminal's capability information determines that the maximum transmission power of each panel among multiple panels under STxMP transmission supports full-power transmission. This means that the sum of the transmission power of multiple panels of the terminal under STxMP transmission is no longer limited by the maximum transmission power defined by the terminal's power level, but rather each panel can achieve full-power transmission, thereby improving the transmission quality of uplink transmission and the system transmission throughput.
[0178] In a terminal capability information determination method provided in this embodiment, when the terminal does not have the capability information, that is, when the maximum transmission power of each panel in the multiple panels under STxMP transmission does not support full power transmission, the sum of the maximum transmission power of each panel in the multiple panels is determined to be lower than or equal to the maximum transmission power determined based on the terminal's power level.
[0179] For example, when the terminal supports uplink STxMP transmission, if the PA capability or power level of panel1 determines that panel1's transmit power can reach 23dBm, and the PA capability or power level of panel2 determines that panel2's transmit power can reach 26dBm, then the sum of the transmit power of panel1 and panel2 can actually reach 27.8dBm. However, since the maximum transmit power defined by the terminal's power level is 26dBm, the sum of the maximum transmit power of panel1 and panel2 can only reach a maximum of 26dBm, and cannot reach the full power transmission of 27.8dBm. In this case, if the terminal's capability information determines that the maximum transmit power of each panel in the multiple panels supports full power transmission under STxMP, then the maximum transmit power of panel1 and panel2 can reach the full power transmission of 27.8dBm. If the terminal does not have capability information, then the sum of the maximum transmit power of panel1 and panel2 can only reach a maximum of 26dBm.
[0180] In a terminal capability information determination method provided in this disclosure embodiment, regardless of whether the terminal possesses capability information or whether it has reported capability information to the network device, since the network device does not know the power information of each panel, the terminal needs to send the power information of each panel to the network device. For example... Figure 5 As shown, it includes the following steps:
[0181] In step S21, power information is sent to the network device.
[0182] The power information is used to indicate the maximum transmit power of each panel in the multiple panels or the power level of each panel.
[0183] In one implementation, when power information is used to indicate the power level of a panel, the maximum transmit power is determined based on the panel's power level. For example, if the panel's power level is PC2, then the panel's maximum transmit power is 26 dBm.
[0184] In a terminal capability information determination method provided in this disclosure embodiment, the power information does not include panel identifiers, and the multiple panels of the terminal are symmetrical panels and / or asymmetrical panels.
[0185] All symmetrical panels have the same maximum transmit power or power rating. Asymmetrical panels have different maximum transmit power or power ratings.
[0186] In some embodiments of a terminal capability information determination method provided in this disclosure, the multiple panels of the terminal are symmetrical panels, and the power information includes the level information of at least one of the symmetrical panels.
[0187] In one implementation, since the multiple panels of the terminal are symmetrical panels, the maximum transmission power and power level of the multiple panels of the terminal are the same. In this case, the terminal only needs to report the maximum transmission power or power level of one symmetrical panel, and the network device can determine the maximum transmission power of each panel.
[0188] In some other embodiments of a terminal capability information determination method provided in this disclosure, the multiple panels of the terminal are asymmetric panels, and the power information includes the power information of all asymmetric panels in the asymmetric antenna panel.
[0189] In one implementation, since the terminal's multiple panels are asymmetric panels, their maximum transmit power and power levels are different. In this case, the terminal needs to report the power information of all asymmetric panels. For example, the terminal reports the power information of all asymmetric panels based on beamforming, or based on beamforming CSI.
[0190] In a terminal capability information determination method provided in this embodiment, the power information includes panel identifiers of multiple panels, and there is a correspondence between the panel identifiers of multiple panels and the maximum transmission power or power level of multiple panels.
[0191] In this embodiment of the disclosure, the power information includes panel identifiers of multiple panels. Each panel has a corresponding panel identifier and a corresponding maximum transmission power or power level. The network device can determine the maximum transmission power or power level of each panel based on the panel identifier of each panel, thereby knowing the maximum transmission power of each panel.
[0192] In a terminal capability information determination method provided in this embodiment, when the terminal has capability information, the sum of the maximum transmission power of multiple panels under STxMP transmission is higher than the maximum transmission power corresponding to the terminal's power level.
[0193] For example, the terminal uses two panels for STxMP transmission. The maximum transmit power of panel1 is 26dBm, and the maximum transmit power of panel2 is 23dBm. The sum of the maximum transmit power of panel1 and panel2 is 27.8dBm, and the maximum transmit power corresponding to the terminal's power level is 26dBm.
[0194] In this embodiment of the disclosure, when the terminal has capability information, the maximum transmission power of each panel in the multiple panels under STxMP transmission supports full-power transmission. That is, the maximum transmission power of the multiple panels is no longer limited to the maximum transmission power corresponding to the power level of the terminal. The sum of the maximum transmission power of the multiple panels can be higher than the maximum transmission power corresponding to the power level of the terminal, thereby improving the transmission quality of uplink transmission and the system transmission throughput.
[0195] In a terminal capability information determination method provided in this disclosure embodiment, the sum of the maximum transmission power of multiple panels of the terminal under STxMP transmission is less than or equal to a first power threshold and greater than or equal to a second power threshold. The first power threshold is greater than the second power threshold.
[0196] In a terminal capability information determination method provided in this disclosure embodiment, the first power threshold is determined based on the maximum transmission power allowed by the terminal on the current carrier and the transmission power corresponding to the power level of each panel.
[0197] In a terminal capability information determination method provided in this disclosure embodiment, the second power threshold is determined based on the transmission power corresponding to the power level of each panel and the maximum transmission power of the terminal under STxMP transmission.
[0198] The maximum transmit power of the terminal under STxMP transmission is determined based on the sum of the transmit powers corresponding to the power levels of multiple panels.
[0199] In this embodiment, the maximum transmission power of each panel is enhanced so that the maximum transmission power of each panel can support higher full-power transmission. Therefore, the sum of the maximum transmission power of multiple panels also needs to be enhanced. This embodiment enhances the sum of the maximum transmission power of multiple panels by redefining the first power threshold and the second power threshold, so that the sum of the maximum transmission power of multiple panels can be higher than the maximum transmission power corresponding to the power level of the terminal, thereby improving the transmission quality of uplink transmission and the system transmission throughput.
[0200] In a terminal capability information determination method provided in this embodiment, the terminal performs STxMP transmission under S-DCI, and the transmission channel / signal corresponding to the STxMP transmission includes at least one of the following:
[0201] PUSCH;
[0202] PUCCH;
[0203] Sounding reference signal (SRS).
[0204] In a terminal capability information determination method provided in this disclosure embodiment, the terminal performs STxMP transmission under M-DCI, and the transmission channel / signal corresponding to the STxMP transmission includes at least one of the following:
[0205] PUSCH and PUSCH;
[0206] PUCCH and PUCCH;
[0207] PUSCH and PUCCH;
[0208] SRS and SRS;
[0209] SRS and PUCCH;
[0210] SRS and PUSCH.
[0211] In this embodiment of the disclosure, when the transmission channel / signal corresponding to the STxMP transmission is any one of the above, and it is determined that the terminal has capability information, the maximum transmission capability of each panel adopts full-power transmission.
[0212] In a terminal capability information determination method provided in this disclosure embodiment, capability information and / or power information are carried in at least one of the following signaling:
[0213] Radio Resource Control (RRC) signaling;
[0214] Media Access Control Element (MAC-CE);
[0215] Uplink Control Information (UCI).
[0216] Capability information and power information can be carried in the same signaling or in different signaling.
[0217] Based on the same concept, this disclosure also provides a method for determining terminal capability information, which is executed by a network device.
[0218] Figure 6 This is a flowchart illustrating a method for determining terminal capability information according to an exemplary embodiment, such as... Figure 6 As shown, the method for determining terminal capability information is executed by the network device and includes the following steps.
[0219] In step S31, the capability information sent by the receiving terminal is received.
[0220] The capability information is used to indicate that when the terminal is transmitting in uplink STxMP and the sum of the transmission power of different panels under STxMP transmission is higher than the maximum transmission power determined based on the terminal's power level, the maximum transmission power of each panel in the multiple panels under STxMP transmission supports full-power transmission. The full power is determined based on the PA capability of each panel in the multiple panels or the power level of each panel.
[0221] In some embodiments, the capability information may be maximum transmit power capability information (HignPowerLimitSTxMP).
[0222] In some embodiments, the panel's PA capability is used to determine the panel's actual maximum transmit power, and the panel's power level is used to determine the panel's maximum transmit power based on the power level definition.
[0223] For example, if the terminal uses two panels for STxMP transmission, and the maximum transmit power of panel1 is defined as 26dBm based on the power level, and the maximum transmit power of panel2 is defined as 23dBm based on the power level, then the full power of panel1 and panel2 is 27.8dBm.
[0224] For example, if a terminal transmits STxMP data through two panels, and the actual transmission power of panel1, determined based on the PA capability, is 23dBm, and the actual transmission power of panel2, determined based on the PA capability, is also 23dBm, then the full power of panel1 and panel2 is 26dBm.
[0225] In some embodiments, when the terminal supports uplink STxMP transmission, the transmit power of panel1 is determined to be 23dBm based on the PA capability or power level of panel1, and the transmit power of panel2 is determined to be 26dBm based on the PA capability or power level of panel2. Therefore, the sum of the transmit powers of panel1 and panel2 can actually reach 27.8dBm. However, since the maximum transmit power defined by the terminal's power level is 26dBm, the sum of the maximum transmit powers of panel1 and panel2 can only reach a maximum of 26dBm, and cannot achieve the full-power transmit power of 27.8dBm. In this case, by determining through the terminal's capability information that the maximum transmit power of each panel in the multiple panels supports full-power transmission under STxMP transmission, the maximum transmit power of panel1 and panel2 can reach the full-power transmit power of 27.8dBm.
[0226] In this embodiment of the disclosure, by receiving capability information sent by the terminal, the network device can determine that when the terminal supports STxMP transmission and the sum of the transmission power of different panels under STxMP transmission is higher than the maximum transmission power determined based on the terminal's power level, the maximum transmission power of each panel under STxMP transmission supports full-power transmission. This means that the sum of the transmission power of multiple panels under STxMP transmission is no longer limited by the maximum transmission power defined by the terminal's power level, but each panel can achieve full-power transmission, thereby improving the transmission quality of uplink transmission and the system transmission throughput.
[0227] In a terminal capability information determination method provided in this embodiment, when the network device does not receive capability information sent by the terminal, and the maximum transmission power of each antenna panel in the multiple antenna panels under STxMP transmission does not support full-power transmission, then it is determined that the sum of the maximum transmission power of each antenna panel in the multiple antenna panels is lower than or equal to the maximum transmission power determined based on the terminal's power level.
[0228] For example, when the terminal supports uplink STxMP transmission, if the PA capability or power level of panel1 determines that panel1's transmit power can reach 23dBm, and the PA capability or power level of panel2 determines that panel2's transmit power can reach 26dBm, then the sum of the transmit power of panel1 and panel2 can actually reach 27.8dBm. However, since the maximum transmit power defined by the terminal's power level is 26dBm, the sum of the maximum transmit power of panel1 and panel2 can only reach a maximum of 26dBm, and cannot reach the full power transmission of 27.8dBm. If the terminal's capability information is received and determines that the maximum transmit power of each panel in the multiple panels supports full power transmission under STxMP, then the maximum transmit power of panel1 and panel2 can reach the full power transmission of 27.8dBm. If the terminal's capability information is not received, then the sum of the maximum transmit power of panel1 and panel2 can only reach a maximum of 26dBm.
[0229] In a terminal capability information determination method provided in this disclosure embodiment, regardless of whether the network device receives capability information sent by the terminal, it needs to receive the power information of each panel reported by the terminal. For example... Figure 7 As shown, it includes the following steps:
[0230] In step S41, the power information sent by the receiving terminal is received.
[0231] The power information is used to indicate the maximum transmit power of each panel in the multiple panels or the power level of each panel.
[0232] In one implementation, when power information is used to indicate the power level of a panel, the maximum transmit power is determined based on the panel's power level. For example, if the panel's power level is PC2, then the panel's maximum transmit power is 26 dBm.
[0233] In a terminal capability information determination method provided in this disclosure embodiment, the power information does not include panel identifiers, and the multiple panels of the terminal are symmetrical panels and / or asymmetrical panels.
[0234] All symmetrical panels have the same maximum transmit power or power rating. Asymmetrical panels have different maximum transmit power or power ratings.
[0235] In some embodiments of a terminal capability information determination method provided in this disclosure, the multiple panels of the terminal are symmetrical panels, and the power information includes the level information of at least one of the symmetrical panels.
[0236] In one implementation, since the multiple panels of the terminal are symmetrical panels, the maximum transmission power and power level of the multiple panels of the terminal are the same. In this case, the terminal only needs to report the maximum transmission power or power level of one symmetrical panel, and the network device can determine the maximum transmission power of each panel.
[0237] In some other embodiments of a terminal capability information determination method provided in this disclosure, the multiple panels of the terminal are asymmetric panels, and the power information includes the power information of all asymmetric panels in the asymmetric antenna panel.
[0238] In one implementation, since the terminal's multiple panels are asymmetric panels, their maximum transmit power and power levels are different. In this case, the terminal needs to report the power information of all asymmetric panels. For example, the terminal reports the power information of all asymmetric panels based on beamforming, or based on beamforming CSI.
[0239] In a terminal capability information determination method provided in this embodiment, the power information includes panel identifiers of multiple panels, and there is a correspondence between the panel identifiers of multiple panels and the maximum transmission power or power level of multiple panels.
[0240] In this embodiment of the disclosure, the power information includes panel identifiers of multiple panels. Each panel has a corresponding panel identifier and a corresponding maximum transmission power or power level. The network device can determine the maximum transmission power or power level of each panel based on the panel identifier of each panel, thereby knowing the maximum transmission power of each panel.
[0241] In a terminal capability information determination method provided in this embodiment, when the terminal has capability information, the sum of the maximum transmission power of multiple panels under STxMP transmission is higher than the maximum transmission power corresponding to the terminal's power level.
[0242] For example, the terminal uses two panels for STxMP transmission. The maximum transmit power of panel1 is 26dBm, and the maximum transmit power of panel2 is 23dBm. The sum of the maximum transmit power of panel1 and panel2 is 27.8dBm, and the maximum transmit power corresponding to the terminal's power level is 26dBm.
[0243] In this embodiment of the disclosure, when the terminal has capability information, the maximum transmission power of each panel in the multiple panels under STxMP transmission supports full-power transmission. That is, the maximum transmission power of the multiple panels is no longer limited to the maximum transmission power corresponding to the power level of the terminal. The sum of the maximum transmission power of the multiple panels can be higher than the maximum transmission power corresponding to the power level of the terminal, thereby improving the transmission quality of uplink transmission and the system transmission throughput.
[0244] In a terminal capability information determination method provided in this disclosure embodiment, the sum of the maximum transmission power of multiple panels of the terminal under STxMP transmission is less than or equal to a first power threshold and greater than or equal to a second power threshold. The first power threshold is greater than the second power threshold.
[0245] In a terminal capability information determination method provided in this embodiment, the first power threshold is determined based on the maximum allowable transmission power of the terminal on the current carrier and the transmission power corresponding to the power level of each panel.
[0246] In a terminal capability information determination method provided in this disclosure embodiment, the second power threshold is determined based on the transmission power corresponding to the power level of each panel and the maximum transmission power of the terminal under STxMP transmission.
[0247] The maximum transmit power of the terminal under STxMP transmission is determined based on the sum of the transmit powers corresponding to the power levels of multiple panels.
[0248] In this embodiment, the maximum transmission power of each panel is enhanced so that the maximum transmission power of each panel can support higher full-power transmission. Therefore, the sum of the maximum transmission power of multiple panels also needs to be enhanced. This embodiment enhances the sum of the maximum transmission power of multiple panels by redefining the first power threshold and the second power threshold, so that the sum of the maximum transmission power of multiple panels can be higher than the maximum transmission power corresponding to the power level of the terminal, thereby improving the transmission quality of uplink transmission and the system transmission throughput.
[0249] In a terminal capability information determination method provided in this embodiment, the terminal performs STxMP transmission under S-DCI, and the transmission channel / signal corresponding to the STxMP transmission includes at least one of the following:
[0250] PUSCH;
