[0097] As shown in FIG. 1A, the communication system 100 includes a terminal 101 and a network device 102.

[0098] In some embodiments, the terminal 101 includes at least one of a mobile phone, a wearable device, an Internet of Things device, a communication-capable automobile, a smart automobile, a Pad, a computer with wireless transceiver function, a virtual reality (VR) terminal device, an augmented reality (AR) terminal device, a wireless terminal device in industrial control, a wireless terminal device in self-driving, a wireless terminal device in remote medical surgery, a wireless terminal device in a smart grid, a wireless terminal device in transportation safety, a wireless terminal device in a smart city, a wireless terminal device in a smart home, and the like, but is not limited thereto.

[0099] In some embodiments, the network device 102 includes at least one of an access network device, a core network device, and the like, but is not limited thereto.

[0100] In some embodiments, the access network device is, for example, a node or device that accesses a terminal to a wireless network, and the access network device can include at least one of an evolved NodeB (eNB) in a 5G communication system, a next generation eNB (ng-eNB), a next generation NodeB (gNB), a node B (NB), a home node B (HNB), a home evolved node B (HeNB), a wireless backhaul device, a radio network controller (RNC), a base station controller (BSC), a base transceiver station (BTS), a base band unit (BBU), a mobile switching center, a base station in a 6G communication system, an open base station (Open RAN), a cloud base station (Cloud RAN), a base station in other communication systems, an access node in a Wi-Fi system, but is not limited thereto.

[0101] In some embodiments, the technical solutions of the present disclosure can be applied to an Open RAN architecture, at this time, the interfaces between or within the access network devices involved in the embodiments of the present disclosure can become internal interfaces of the Open RAN, and the processes and information interactions between these internal interfaces can be realized through software or programs.

[0102] In some embodiments, the access network device can be composed of a central unit (CU) and a distributed unit (DU), wherein the CU can also be referred to as a control unit. The CU-DU structure can split the protocol layers of the access network device, and part of the functions of the protocol layers are controlled by the CU, and the remaining part or all of the functions of the protocol layers are distributed in the DU and controlled by the CU, but the present disclosure is not limited thereto.

[0103] In some embodiments, the core network device can be one device including multiple network elements, etc., or can be multiple devices or device groups, each including all or part of multiple network elements. The network element can be virtual or physical. The core network includes, for example, at least one of an evolved packet core (EPC), a 5G core network (5GCN), and a next generation core (NGC).

[0104] In some embodiments, the network device can configure an uplink subband (UL subband) on a downlink (DL) time unit or a flexible time unit, and a terminal can send first uplink information on the UL subband, and the time-frequency domain resources of the UL subband can be determined by explicit configuration.

[0105] For example, as shown in FIG. 1B, the downlink time unit or the flexible time unit configured with the uplink subband can be referred to as an SBFD time unit, such as slot#(n+1), slot#(n+2), and slot#(n+3). The uplink time unit that can only perform uplink transmission or the downlink time unit that can only perform downlink transmission is referred to as a non-SBFD time unit, such as slot#n, slot#(n+4), and slot#(n+5) in FIG. 1B.

[0106] On the SBFD time unit, the terminal can transmit uplink data on the UL subband. At this time, if there is another terminal, for example, a legacy terminal, receiving downlink data within a downlink subband (DL subband), to reduce interference on the reception of the downlink data, the terminal can adjust the transmission beam on the UL subband. On the non-SBFD time unit, all terminals in the cell transmit uplink data, and there is no problem of interference between terminals, so that the terminal adopts different uplink power control on the SBFD time unit and the non-SBFD time unit.

[0107] For the network device, on the SBFD time unit, the network device can need to simultaneously receive uplink data and transmit downlink data, and on the non-SBFD time unit, the network device only needs to receive uplink data or transmit downlink data. The network device can adopt different antenna configurations on the SBFD time unit and the non-SBFD time unit, so as to correspond to different spatial relations, and also cause the network device to need to configure different power control parameters on the SBFD time unit and the non-SBFD time unit.

[0108] In some embodiments, taking the physical uplink shared channel (PUSCH) as an example, the power control parameter corresponding to the PUSCH can be determined based on the following formula 1:

[0109] wherein, P CMAX,f,c (i) is the maximum output power of the terminal, P O_PUSCH，b,f,c(j) is the standard terminal transmission power, M SRS,b,f,c (i) is the number of resource blocks (RB) occupied by uplink transmission, μ is the subcarrier spacing (SCS), α b,f,c (j) is the power adjustment factor, PL b,f,c (qd) is the downlink loss estimation, Δ TF,f,b,c (i) is the relevant parameter of the number of bits per resource element (BPRE), f b,f,c (i, l) is the closed-loop power control related parameter. Wherein, Corresponding closed-loop power control parameters, corresponding values can be determined based on absolute power control parameters, but also can be determined based on power control cumulative parameters, corresponding closed-loop power control parameters can be determined by the transmission power control command field (TPC command field) of the downlink control information (DCI), but also can be determined based on other indication signaling.

[0110] For example, if the radio resource control (RRC) parameter TPC accumulation parameter (tpc-Accumulation) is disabled, the terminal adjusts the corresponding PUSCH closed-loop power control value based on the absolute power control parameter indicated by the TPC command field of the scheduling DCI.

[0111] For example, if tpc-Accumulation is enabled, the terminal adjusts the PUSCH closed-loop power control value based on at least one cumulative power control parameter indicated by the TPC command field of at least one DCI within a period of time.

[0112] For example, as shown in FIG. 1C, the closed-loop power control value at time i = cumulative power control parameter within a time window before time i + open-loop power. Wherein, the starting time of the time window can be ahead of time i or located at time i.

[0113] It is worth noting that other uplink information, such as sounding reference signal (SRS), physical uplink control channel (PUCCH), also follows the above power control mechanism, which will not be repeated here.

[0114] The current power control mechanism does not consider the SBFD scenario, and accordingly, the present disclosure provides the following information transmission method, terminal, network device and system, and storage medium.

[0115] FIG. 2 is an interaction diagram of an information transmission method according to an embodiment of the present disclosure. As shown in FIG. 2, the present embodiment of the present disclosure relates to an information transmission method, and the method comprises:

[0116] In step S2101, the network device 102 sends second signaling to the terminal 101.

[0117] In some embodiments, the second signaling is used to indicate a first time window. The first time window is used to transmit second uplink information. That is, the second uplink information is transmitted within the first time window.

[0118] It can be understood that the second uplink information can include, but is not limited to, at least one of the following: a physical uplink shared channel (PUSCH); a physical uplink control channel (PUCCH); and a sounding reference signal (SRS). In some embodiments, the second signaling can include, but is not limited to, at least one of the following:

[0119] RRC signaling; DCI; and a medium access control control element (MAC CE).

[0120] In some embodiments, the second signaling is RRC signaling, which can be configured by a PUSCH power control parameter PUSCH-powerControl or by a sounding reference signal configuration parameter SRS-config.

[0121] In some embodiments, the second signaling can configure at least one of the following:

[0122] a starting time unit of the first time window;

[0123] a number of time units within the first time window;

[0124] an ending time unit of the first time window.

[0125] In the embodiments of the present disclosure, a time unit can be in units of a slot, a symbol, a sub-slot, a frame, a subframe, etc., which are not limited in the present disclosure. Wherein, one sub-slot includes one or more continuous symbols belonging to the same slot.

[0126] In some embodiments, step S2101 can be optionally performed, and step S2101 can not be performed if the network device 102 and the terminal 101 determine the first time window based on a predefined manner.

[0127] In step S2102, the network device 102 determines the first time window.

[0128] In some embodiments, the network device 102 can determine the first time window based on a predefined manner, and the specific determination manner will be introduced in step S2103, which is not introduced here for the moment.

[0129] In some embodiments, step S2102 and step S2101 can be alternatively performed. For example, when the network device 102 configures the first time window for the terminal 101, step S2101 can be performed, and when the network device 102 and the terminal 101 determine the first time window based on a predefined manner, step S2102 can be performed.

[0130] In step S2103, the terminal 101 determines the first time window.

[0131] In some embodiments, the terminal 101 can determine the first time window based on the second signaling sent by the network device 102.

[0132] For example, the second signaling configures that the starting time unit of the first time window is slot #1 and the ending time unit is slot #4, and the terminal 101 can determine that the first time window includes slot #1, slot #2, slot #3 and slot #4.

[0133] For another example, the second signaling configures that the starting time unit of the first time window is slot #1 and the number of included time units is 4, and the terminal 101 can determine that the first time window includes slot #1, slot #2, slot #3 and slot #4.

[0134] In some embodiments, the terminal 101 can determine the first time window based on a predefined manner.

[0135] In one example, the starting time unit of the first time window is N symbols before the PUSCH transmission occasion (i-i0). For example, N=K PUSCH (i-i0)-1.

[0136] In one example, the ending time unit of the first time window is M symbols before the PUSCH transmission occasion i. For example, M=KPUSCH (i).

[0137] wherein i0>0 and K is the smallest integer satisfying i-i0-K PUSCH (i) <i-K PUSCH (i-i0).

[0138] corresponding to K PUSCH (i) is determined based on the following ways:

[0139] If the PUSCH transmission is scheduled based on DCI, K PUSCH (i) is the number of symbols after the last symbol of the PDCCH corresponding to the DCI triggering the PUSCH transmission and before the first symbol of the PUSCH transmission, as shown in FIG. 1C.

[0140] If the PUSCH is scheduled based on Configured Grant (CG), for example, ConfiguredGrantConfig, K PUSCH (i) is equal to the product of the number of symbols per slot and the minimum value provided by k2 in the PUSCH common configuration PUSCH-ConfigCommon.

[0141] The above is only an exemplary description, and the present disclosure does not limit the scheme of determining the first time window based on a predefined manner.

[0142] In step S2104, the network device 102 sends first signaling to the terminal 101.

[0143] In some embodiments, the first signaling is used by the terminal 101 to determine, within the first time window, a cumulative power control parameter for transmitting second uplink information on at least one type of time unit.

[0144] The second uplink information can be at least one of PUSCH, PUCCH, and SRS.

[0145] It can be understood that the second uplink information here and the first uplink information mentioned in the subsequent steps are uplink information transmitted by the terminal 101 at different times. The uplink information transmitted by the terminal 101 within the first time window is referred to as the second uplink information, and the uplink information that needs to be transmitted by the terminal 101 after the first time window is referred to as the first uplink information.

[0146] For example, within the first time window, the terminal 101 transmits PUSCH#1, and at a certain time after the first time window, the terminal 101 transmits PUSCH#2.

[0147] The type of time unit can include, but is not limited to, at least one of the following:

[0148] The first type may be, for example, SBFD.

[0149] The second type may be, for example, non-SBFD.

[0150] The first type refers to a downlink time unit configured with an uplink subband or a flexible time unit configured with an uplink subband, or an uplink time unit configured with a downlink subband or a flexible time unit configured with a downlink subband.

[0151] The second type refers to a downlink time unit not configured with an uplink subband, or an uplink time unit not configured with a downlink subband, or a flexible time unit not configured with any subband.

[0152] The above is only an example, and the time unit may be classified in other manners, which is not limited in the present disclosure.

[0153] In some embodiments, the first signaling may include at least one of the following: DCI; RRC signaling; MAC CE.

[0154] In some embodiments, the first signaling may include at least one first information field, wherein the first information field is an information field related to a power control parameter.

[0155] In one example, the first signaling is DCI, and the first information field may be a TPC command field.

[0156] In one example, the first signaling is RRC signaling or MAC CE, and the first information field may be an information field of a newly added or existing power control parameter.

[0157] In one example, the first signaling includes one first information field.

[0158] For example, the first information field may be associated with the first type, and the first information field may be used to indicate a first power control parameter for transmitting the second uplink information in a first time unit. The first time unit is a time unit of the first type in the first time window. The first power control parameter is a parameter used to determine the actual power control parameter.

[0159] It should be noted that the association of the first information field with the first type may be understood as that the power control parameter indicated by the first information field is used to determine the first power control parameter for transmitting the second uplink information in the time unit of the first type (specifically, the first time unit described above).

[0160] Exemplarily, the first information field can be associated with the second type, and the first information field can be used to indicate a second power control parameter for transmitting the second uplink information in a second time unit of the second type. The second time unit is one time unit of the second type in the first time window. The second power control parameter can be a parameter used to determine the actual power control parameter.

[0161] It should be noted that the first information field being associated with the second type can be understood as that the power control parameter indicated by the first information field is used to determine a second power control parameter for transmitting the second uplink information in a time unit of the second type (specifically, the second time unit mentioned above).

[0162] When the number of the first information fields is 1, which first type the first information field is associated with will be introduced in step S2105, and will not be introduced here.

[0163] In one example, the first signaling includes a plurality of first information fields, and the plurality of first information fields are respectively associated with different types of time units.

[0164] Exemplarily, the first signaling includes two first information fields. One of the two first information fields is associated with the first type, and the other is associated with the second type.

[0165] The first information field associated with the first type can be used to indicate a first power control parameter for transmitting the second uplink information in a first time unit of the first type. The first time unit is one time unit of the first type in the first time window. The first power control parameter can be a parameter used to determine the actual power control parameter.

[0166] The first information field associated with the second type can be used to indicate a second power control parameter for transmitting the second uplink information in a second time unit of the second type. The second time unit is one time unit of the second type in the first time window. The first power control parameter can be a parameter used to determine the actual power control parameter.

[0167] The terminal 101 can determine the type of the time unit associated with each first information field based on a predefined manner, which will be introduced in step S2105, and will not be introduced here.

[0168] In step S2105, the terminal 101 determines the accumulated power control parameter in the time unit of at least one type based on the first signaling.

[0169] In some embodiments, the first signaling includes one first information field, and the terminal 101 can determine the type of the time unit associated with the first information field in the following manner:

[0170] determine a type of time unit associated with the first information field in the first signaling based on a type of time unit in which the uplink transmission scheduled by the first signaling is located.

[0171] Exemplarily, the time unit in which the uplink transmission scheduled by the first signaling is located is of a first type, e.g., SBFD, the terminal 101 can determine that the first information field in the first signaling is associated with the first type, e.g., SBFD.

[0172] Exemplarily, the time unit in which the uplink transmission scheduled by the first signaling is located is of a second type, e.g., non-SBFD, the terminal 101 can determine that the first information field in the first signaling is associated with the second type, e.g., non-SBFD.

[0173] Taking DCI as an example of the first signaling, if the PUSCH scheduled by the first information field in DCI#1 is transmitted on an SBFD time unit, the terminal 101 determines that the first information field in DCI#1 is associated with SBFD. If the PUSCH scheduled by the first information field in DCI#2 is transmitted on a non-SBFD time unit, the terminal 101 determines that the first information field in DCI#2 is associated with non-SBFD.

[0174] In some embodiments, the first signaling includes multiple first information fields, and the terminal 101 can determine the type of time unit associated with each first information field based on a predefined manner.

[0175] Exemplarily, it can be agreed by a protocol that the first information field with an index value of 1 is associated with the first type, and the first information field with an index value of 2 is associated with the second type.

[0176] Taking DCI as an example of the first signaling, the terminal 101 determines that the first information #1 in DCI#1 is associated with SBFD, and the first information #2 is associated with non-SBFD.

[0177] In some embodiments, the first information field is associated with the first type, and the terminal 101 determines a first power control parameter for transmitting a second uplink information on a first time unit based on a power control parameter indicated by the first information field.

[0178] Exemplarily, taking DCI as an example of the first signaling, the DCI includes a first information field, the first information field is associated with SBFD, and the first information field indicates a closed-loop power control parameter f b,f,c (i,l), the terminal 101 can calculate a first power control parameter for transmitting a second uplink information on a first time unit of SBFD type based on formula 1.

[0179] wherein P CMAX,f,c (i) is the maximum output power of the terminal, PO_PUSCH，b,f,c (j) is the standard terminal transmission power, M SRS,b,f,c (i) is the number of resource blocks (RB) occupied by uplink transmission, μ is the subcarrier spacing (SCS), α b,f,c (j) is the power adjustment factor, PL b,f,c (qd) is the downlink loss estimate, Δ TF,f,b,c (i) is the relevant parameter of the number of bits per resource element (BPRE), f b,f,c (i, l) is the closed loop power control related parameter.

[0180] wherein, The corresponding closed loop power control parameter corresponds to the value which can be determined based on the absolute power control parameter, or can be determined based on the power control cumulative parameter, and the corresponding closed loop power control parameter can be determined by the transmission power control command field (TPC command field) of the downlink control information (DCI), or can be determined based on other indication signaling.

[0181] In some embodiments, the first information field is associated with the second type, and the terminal 101 determines the power control parameter indicated by the first information field as the second power control parameter for transmitting the second uplink information in the second time unit. For example, the first signaling is DCI, and the DCI includes a first information field associated with non-SBFD, and the first information field indicates a closed loop power control parameter f b,f,c (i, l), and the terminal 101 calculates the second power control parameter for transmitting the second uplink information in the second time unit of the non-SBFD based on the foregoing formula 1. The specific process is similar to the foregoing manner, and will not be described here.

[0182] In some embodiments, further, the terminal 101 can determine the cumulative power control parameter in at least one time unit in any of the following ways:

[0183] Method 1: The cumulative power control parameter in each type of time unit is related to the type of time unit.

[0184] In one example, the terminal 101 determines the first power control parameter for transmitting the second uplink information in each first time unit within the first time window based on the at least one first information field in the first signaling. The terminal 101 can then calculate the sum of the first power control parameter for transmitting the second uplink information in each first time unit within the first time window, and obtain a first sum value.

[0185] Further, it can be determined that the first accumulated power control parameter in the first type of time unit is equal to the first sum value. Here, the first type of time unit is the first type of time unit for transmitting the first uplink information after the first time window.

[0186] In one example, the terminal 101 determines the second power control parameter for transmitting the second uplink information in each second time unit within the first time window based on the first signaling. The terminal 101 can then calculate the sum of the second power control parameter for transmitting the second uplink information in each second time unit within the first time window, and obtain a second sum value. Further, it can be determined that the second accumulated power control parameter in the second type of time unit is equal to the second sum value. Here, the second type of time unit is after the first time window.

[0187] For example, the first time window includes 5 time units, of which 3 are first time units and 2 are second time units. The first time units are all SBFD time units, and the second time units are all non-SBFD time units. The terminal 101 determines the first power control parameter for transmitting the second uplink information in each of the 3 first time units based on the first signaling, and assumes that they are P n1 , P n2 , and P n3 , respectively. The first sum value is P n1 + P n2 + P n3 . The terminal 101 can then determine that the first accumulated power control parameter for transmitting the second uplink information in the SBFD time unit is equal to (P n1 + P n2 + P n3 ).

[0188] In addition, the terminal 101 determines the second power control parameter for transmitting the second uplink information in each of the 2 second time units based on the first signaling, and assumes that they are P m1 and P m2 , respectively. The second sum value is P m1 + P m2 . The terminal 101 can then determine that the second accumulated power control parameter for transmitting the second uplink information in the non-SBFD time unit is equal to (P m1 + P m2 ).

[0189] Understandably, if there is only one type of time unit within the first time window, such as only an SBFD time unit, then only the first cumulative power control parameter needs to be determined. Or, if there is only an SBFD time unit, then only the second cumulative power control parameter needs to be determined.

[0190] Method 2: The cumulative power control parameters on each type of time unit are related to multiple types of time units.

[0191] In one example, terminal 101 previously determined the first power control parameters for transmitting the second uplink information in the first time unit based on the first signaling. The specific determination method has been described in the previous embodiments and will not be repeated here. At this time, terminal 101 can calculate the sum of the first power control parameters for transmitting the second uplink information in each first time unit within the first time window, thereby obtaining the first sum.

[0192] In one example, terminal 101 previously determined the second power control parameters for transmitting the second uplink information in the second time unit based on the first signaling. At this time, terminal 101 can calculate the sum of the second power control parameters for transmitting the second uplink information in each second time unit within the first time window, thereby obtaining the second sum.

[0193] Furthermore, the sum of the first and second sums can be calculated to obtain the third sum.

[0194] Terminal 101 can determine that the first cumulative power control parameter for transmitting second uplink information on the first type of time unit is equal to the third sum. Here, the first type of time unit is located after the first time window. And / or

[0195] Terminal 101 can determine that the second cumulative power control parameter for transmitting the second uplink information in the second type of time unit is equal to the third sum value. Here, the second type of time unit is located after the first time window.

[0196] For example, the first time window includes 5 time units, of which 3 are first time units and 2 are second time units. All first time units are SBFD time units, and all second time units are non-SBFD time units. Based on the first signaling, terminal 101 determines the first power control parameters for transmitting second uplink information in the 3 first time units, assuming they are P... n1 P n2 P n3 Then the first sum is (P) n1 +P n2 +P n3 ).

[0197] In addition, the terminal 101 determines, based on the first signaling, a second power control parameter for transmitting the second uplink information on the two second time units respectively, assuming P m1 m2 , and a second sum value is P m1 +P m2 .

[0198] At this time, the sum value between the first sum value and the second sum value can be determined to obtain a third sum value, the third sum value = P n1 +P n2 +P n3 +P m1 +P m2 .

[0199] The terminal 101 determines that the first cumulative power control parameter for transmitting the first uplink information on the SBFD time unit is equal to (P n1 +P n2 +P n3 +P m1 +P m2 ). And / or, the second cumulative power control parameter for transmitting the first uplink information on the non-SBFD time unit is equal to (P n1 +P n2 +P n3 +P m1 +P m2 ).

[0200] In step S2106, the terminal 101 determines the actual power control parameter based on the cumulative power control parameter.

[0201] In some embodiments, after the terminal 101 determines the first cumulative power control parameter P1, the terminal 101 can calculate the actual power control parameter P1' for transmitting the first uplink information on the first type of time unit based on the following formula 2: P1' = P1 + P Formula 2

[0202] Wherein, P can be a parameter for determining the actual power control parameter P1', and P can be an open loop power control parameter, for example. The open loop power control parameter refers to a parameter for adjusting the transmission power of the network device according to the received forward (or reverse) link signal power, which can be used to compensate for the average path loss and slow fading in the channel.

[0203] In some embodiments, after the terminal 101 determines the second cumulative power control parameter P2, the terminal 101 can calculate the actual power control parameter P2' for transmitting the first uplink information on the second type of time unit based on the following formula 3: P2' = P2 + P' Formula 3

[0204] ​P' can be a parameter used to determine the actual power control parameter P2', and P' can be an open loop power control parameter, for example. P and P' can be provided by the network device 102, and can be the same or different, which is not limited in the present disclosure.

[0205] At step S2107, the terminal 101 sends the first uplink information to the network device 102 based on the actual power control parameter.

[0206] In some embodiments, the first uplink information can be at least one of PUSCH, PUCCH, and SRS, which is not limited in the present disclosure.

[0207] In some embodiments, the terminal 101 sends the first uplink information to the network device 102 based on P1' on the SBFD time unit.

[0208] In some embodiments, the terminal 101 sends the first uplink information to the network device 102 based on P2' on the non-SBFD time unit.

[0209] In some embodiments, the network device 102 receives the first uplink information.

[0210] In some embodiments, the names of information, etc. are not limited to the names described in the embodiments, and the terms of "information", "message", "signal", "signaling", "report", "configuration", "indication", "instruction", "command", "channel", "parameter", "domain", "field", "symbol", "symbol", "codebook", "codeword", "code point", "bit", "data", "program", "chip", etc. can be replaced with each other.

[0305] The first time window is determined based on a predefinition, or the base station sends indication signaling to indicate the corresponding time window.

[0306] The network device determines corresponding power control parameters based on the scheduling DCI corresponding to the uplink transmission on the SBFD time unit and the non-SBFD time unit, and the DCI satisfies at least one of the following:

[0312] The corresponding DCI includes one TPC-related indication field;

[0313] The corresponding DCI contains two TPC-related indication fields, the first TPC indication field is applied to non-SBFD uplink transmission, and the second TPC indication field is applied to SBFD uplink transmission.

[0314] The following will illustrate the specific embodiments of the application from the perspective of a terminal.

[0315] Embodiments:

[0316] The terminal transmits uplink data on the UL subband based on the base station configuration on the DL or flexible symbol, assuming that the terminal supports the SBFD feature.

[0317] As described above, the embodiments of the application take PUSCH as an example to illustrate the solutions of the application. The solutions can also be applied to PUCCH, SRS, and other uplink transmission signals or uplink reference signals, and the application does not repeat the description here.

[0318] As described in the background, the embodiments take PUSCH as an example to consider the power control of PUSCH in SBFD and non-SBFD respectively, and design the corresponding solutions to realize the power control of PUSCH in SBFD and non-SBFD respectively. This is conducive to the terminal to perform uplink transmission based on different power control parameters on different time unit types based on different power control parameters.

[0319] Embodiment 1: A possible implementation, under the condition that the signaling indication or pre-defined manner indicates that the closed-loop power control parameter of the corresponding PUSCH is determined based on the cumulative power control parameter, the terminal determines the closed-loop power control of the SBFD corresponding uplink transmission based on the sum of the SBFD corresponding cumulative power control in the first time window, and determines the closed-loop power control of the non-SBFD corresponding uplink transmission based on the sum of the non-SBFD corresponding cumulative power control in the second time window. Illustratively, the closed-loop power control parameter is determined based on the following definition:

[0320] Wherein, the m is the transmission time unit corresponding to the DCI in the first time window, and the δPUSCH,b,f,c(m,l) is indicated based on the TPC command field of the DCI.

[0321] The first time window or the second time window:

[0322] The first time window and the second time window can be the same or different.

[0323] The first time window and / or the second time window can be indicated based on a signaling indication manner or determined based on a pre-defined manner.

[0324] For example, the signaling can be RRC, MAC CE or DCI. For example, the RRC signaling can be based on PUSCH-powerControl configuration or SRS-config configuration, which is not limited by the present application.

[0325] For example, the first time window and / or the second time window corresponding to the PUSCH transmission occasion i can be defined in a predefined manner, for example, the first time window is defined as follows:

[0326] The first time window start time: the time corresponding to N OFDM symbols before the PUSCH transmission occasion i-i0, for example, N=K SRS (i-i0)-1.

[0327] The first time window end time: the time corresponding to M OFDM symbols before the PUSCH transmission occasion i, for example, N=K SRS (i).

[0328] Wherein, i0>0 and is the minimum integer satisfying i-i0-K SRS (i)<i-K SRS (i-i0).

[0329] Corresponding K PUSCH (i) is determined as follows:

[0330] If the PUSCH transmission is based on DCI scheduling, K PUSCH (i) is the number of symbols after the last symbol of the PDCCH corresponding to the DCI triggering the PUSCH transmission and before the first symbol of the PUSCH transmission, as shown in FIG. 1C for example.

[0331] If the PUSCH is based on configured grant (ConfiguredGrant, CG) scheduling, for example, ConfiguredGrantConfig, K PUSCH (i) is equal to the product of the number of symbols per slot and the minimum value provided by k2 in the PUSCH common configuration PUSCH-ConfigCommon.

[0332] For example, the first time window corresponding to the PUSCH is shown in FIG. 4A. Wherein, DCI 0_1 or DCI 0_2 or DCI 0_3 corresponds to the scheduling DCI of the PUSCH.

[0333] Similarly, the first time window corresponding to the SRS is shown in FIG. 4B. Wherein, DCI 2_3 corresponds to the power control parameter indication DCI of the SRS.

[0334] Cumulative power control parameters:

[0335] As described above, the corresponding accumulated power control parameters The terminal determines the closed-loop power control of the SBFD corresponding uplink transmission based on the sum of the accumulated power control parameters corresponding to the SBFD in the first time window, and determines the closed-loop power control of the non-SBFD corresponding uplink transmission based on the sum of the accumulated power control parameters corresponding to the non-SBFD in the second time window.

[0336] For example, the accumulated power control parameter δPUSCH,b,f,c(m,l) can be determined based on signaling indication, and the signaling can be DCI, RRC or MAC CE. The present application takes DCI as an example to describe specific implementation solutions, which can also be applied in RRC or MAC CE.

[0337] For example, the accumulated power control parameter δPUSCH,b,f,c(m,l) is determined based on signaling such as the TPC command field of DCI. The corresponding TPC command field can be determined based on one or more of the following:

[0338] The signaling contains one TPC command field;

[0339] The TPC command field is used to indicate the accumulated power control parameters of SBFD or non-SBFD. For example, if the PUSCH scheduled by DCI 1 is transmitted on the SBFD time unit, the terminal determines that the accumulated power control parameters indicated by the TPC command field corresponding to the DCI 1 are applied to the SBFD time unit. Correspondingly, if the PUSCH scheduled by DCI 2 is transmitted on the non-SBFD time unit, the terminal determines that the accumulated power control parameters indicated by the TPC command field corresponding to the DCI 2 are applied to the non-SBFD time unit.

[0340] The terminal determines the power control parameter f b,f,c (i,l) of the PUSCH transmitted on the SBFD time unit based on the sum of the at least one accumulated power control parameter applied to the SBFD received in the above-mentioned first time window; and correspondingly, the terminal determines the power control parameter f b,f,c (i,l) of the PUSCH transmitted on the non-SBFD time unit based on the sum of the at least one accumulated power control parameter applied to the non-SBFD received in the above-mentioned first time window.

[0341] The signaling contains two TPC command fields;

[0342] For example, the first TPC command field is applied to PUSCH of non-SBFD transmission, and the second TPC command field is applied to PUSCH of SBFD transmission. The terminal determines the power control parameter f b,f,c (i, l) of PUSCH transmitted in the SBFD time unit based on the sum of at least one accumulated power control parameter applied to SBFD received in the first time window b,f,c (i, l) of PUSCH transmitted in the non-SBFD time unit based on the sum of at least one accumulated power control parameter applied to non-SBFD received in the first time window

[0343] Embodiment 2, a possible implementation, under the condition that the signaling indication or the pre-defined manner indicates that the closed-loop power control parameter of the corresponding PUSCH is determined based on the accumulated power control parameter, the terminal determines the closed-loop power control of the SBFD and non-SBFD corresponding uplink transmission based on the sum of the corresponding accumulated power control of the uplink transmission in the first time window, for example, the closed-loop power control parameter is defined as follows: Wherein, the m is the transmission time unit corresponding to the DCI in the first time window, and the δPUSCH,b,f,c(m, l) is indicated based on the TPC command of the DCI.

[0344] The first time window:

[0345] The first time window can be indicated based on the signaling indication manner or determined based on the pre-defined manner.

[0346] For example, the signaling can be RRC, MAC CE or DCI, for example, the RRC signaling can be configured based on PUSCH-powerControl or SRS-config, and the present application does not limit this.

[0347] For example, for the PUSCH corresponding to the transmission occasion i, the first time window can be defined based on the following manner:

[0348] The starting time of the first time window: the time corresponding to the N OFDM symbols before the PUSCH transmission occasion i-i0, for example, N=KSRS(i-i0)-1;

[0349] The end time of the first time window: the time corresponding to the M OFDM symbols before the PUSCH transmission occasion i, for example, N=KSRS(i);

[0350] Wherein, i0>0 and i0 satisfies i-i0-KSRS (i) <i-K SRS (i-i0) is the minimum integer.

[0351] For example, the PUSCH corresponds to the first time window, as shown in FIG. 4A. In this case, the DCI 0_1 or the DCI 0_2 or the DCI 0_3 corresponds to the scheduling DCI of the PUSCH.

[0352] Similarly, the SRS corresponds to the first time window, as shown in FIG. 4B. In this case, the DCI 2_3 corresponds to the power control parameter indication DCI of the SRS.

[0353] Cumulative power control parameters:

[0354] As described above, the cumulative power control parameters The terminal determines the closed-loop power control of the PUSCH corresponding to the SBFD and the non-SBFD based on the sum of the cumulative power control parameters corresponding to the PUSCH in the first time window.

[0355] For example, the cumulative power control parameter δPUSCH,b,f,c(m,l) can be determined based on the signaling indication mode. The signaling can be a DCI, an RRC or a MAC CE. The present application takes the DCI as an example to describe the specific implementation scheme, and the scheme can also be applied in the RRC or the MAC CE.

[0356] For example, the cumulative power control parameter δPUSCH,b,f,c(m,l) is determined based on the TPC command field of the signaling, for example, the DCI. The TPC command field can be determined based on one or more of the following:

[0357] The signaling contains a TPC command field;

[0358] The TPC command field is used to indicate the cumulative power control parameters of the SBFD and / or the non-SBFD. For example, if the PUSCH scheduled by the DCI 1 is transmitted on the SBFD time unit, the terminal determines that the cumulative power control parameters indicated by the TPC command field corresponding to the DCI 1 are applied to the SBFD time unit. Correspondingly, if the PUSCH scheduled by the DCI 2 is transmitted on the non-SBFD time unit, the terminal determines that the cumulative power control parameters indicated by the TPC command field corresponding to the DCI 2 are applied to the non-SBFD time unit.

[0359] The terminal determines the power control parameter f of the PUSCH transmitted on the SBFD or non-SBFD time unit based on the sum of the at least one cumulative power control parameter applied to the SBFD and non-SBFD received in the first time window b,f,c (i, l);

[0360] The signaling includes two TPC command fields;

[0361] For example, the first TPC command field is applied to the PUSCH transmitted on the non-SBFD, and the second TPC command field is applied to the PUSCH transmitted on the SBFD. The terminal determines the power control parameter f of the PUSCH transmitted on the SBFD or non-SBFD time unit based on the sum of the at least one cumulative power control parameter applied to the SBFD and non-SBFD received in the first time window b,f,c (i, l);

[0362] In the SBFD scenario, the embodiments of the present disclosure mainly design a closed-loop power control mechanism for uplink transmission on the SBFD and non-SBFD, respectively.

[0363] Terminal side: The terminal side can determine the closed-loop power control parameter of the uplink transmission on the SBFD time unit and non-SBFD time unit in the SBFD scenario based on the above scheme, and transmit the corresponding uplink transmission based on the corresponding power control.

[0364] Network device side: The network device can determine the uplink transmission related power control parameter based on the above scheme.

[0365] In the embodiments of the present disclosure, part or all of the steps, and optional implementation manners thereof, can be combined with part or all of the steps in other embodiments, or can be combined with optional implementation manners of other embodiments.
