[0072] In order to make the objects, technical solutions and advantages of the embodiments of the present application clearer, the following will be combined with the accompanying drawings for 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 some but not all of the embodiments of the present application. Based on the embodiments in the present application, all other embodiments obtained by a person of ordinary skill in the art without creative work fall within the protection scope of the present application.

[0073] In the present application, “and / or” is only used to describe the relationship of the associated objects, which means that there can be three relationships, for example, A and / or B, which means that there are three cases of A alone, A and B together, and B alone. In addition, the character “ / ” in this paper means that the front and rear associated objects are in an “or” relationship.

[0074] In the present application, “at least one” means one or more. “Multiple” means two or more.

[0075] In the present application, the first, second, etc. description is only for indicating and distinguishing the description objects, and has no order, and does not represent the special limitation of the number of objects in the embodiments of the present application, and cannot constitute any limitation on the embodiments of the present application. For example, the first power and the second power are only used to distinguish the transmission power of the uplink channel corresponding to different transmission resources, and do not represent the difference in priority or importance of the two powers.

[0076] In the present application, “example”, “in some embodiments”, “in other embodiments” and the like are used to represent examples, illustrations or descriptions. Any embodiment or design scheme described as “example” in the present application should not be interpreted as more preferred or more advantageous than other embodiments or design schemes. In fact, the word “example” is intended to present the concept in a specific way.

[0077] In order to facilitate understanding, the related terms involved in the embodiments of the present application are described as follows.

[0078] 1, repetition type (repetition type)

[0079] In some scenarios, such as some deep coverage scenarios, such as cell edge, or basement, etc., the path loss of wireless signal propagation is more serious. In order to improve the uplink transmission performance, repeated transmission can be used. The NR system supports repeated transmission of the first repetition type and the second repetition type. For example, the first repetition type can be repetition type A, and the second repetition type can be repetition type B.

[0080] In the second repetition type application process, N times of repeated sending can be performed, and N is a positive integer. According to the starting time domain symbol position S of the first repetition sending, the repetition sending is performed on the N*L consecutive time domain symbols according to the number of time domain symbols L required by each repetition. That is, from the time domain symbol S of the first slot scheduled, the subsequent N*L time domain symbols (which may extend to other slots) are used for N times of repeated sending. For the repetition transmission of the repetition type B, the starting symbol S and the symbol length L are directly indicated by the starting symbol (startSymbol) and the symbol length (length) in the time domain resource allocation table. Wherein, S is the index of the symbol, S is an integer greater than or equal to 0, and the maximum value of S depends on the number of symbols in the slot, and L is an integer greater than 0.

[0081] For example, the meanings of the starting symbol S and the symbol length L can be understood by referring to Table 6.1.2.1-1 in the standard protocol 38.214 (for example, 38.214 V17.6.0), which will not be described in detail here.

[0082] As shown in FIG. 1, it is an example diagram of PUSCH occupying resources. For the second repetition type of PUSCH repetition transmission, the PUSCH can perform multiple nominal repetition transmissions, and one nominal repetition transmission can be transmitted across slots. The time domain resource allocation (TDRA) field in the downlink control information (DCI) of the network device or the TDRA parameter in the type1 grant-free scheduling indicates the time domain resource of the first nominal repetition transmission, and the time domain resource of the remaining nominal repetition transmission is calculated based on the time domain resource of the first nominal repetition transmission and the uplink (UL) / downlink (DL) slot configuration. If a nominal repetition transmission crosses a slot boundary or a DL / UL switching point, the nominal repetition transmission is split into multiple actual repetition transmissions at the slot boundary or the switching point; and if a nominal repetition transmission includes invalid symbols / unavailable symbols, the nominal repetition transmission is segmented into multiple actual repetition transmissions at the invalid symbols. Therefore, the actual repetition number can be greater than the indicated value of the nominal repetition number.

[0083] As shown in FIG. 2, it is a segmentation diagram of the nominal repetition transmission. When the nominal repetition #0 is transmitted across slots, it can be segmented into actual repetition #0 and actual repetition #1, and when the nominal repetition #1 is transmitted across slots and there are unavailable symbols, it can be segmented into actual repetition #2, actual repetition #3 and actual repetition #4.

[0084] Of course, the nominal repeated transmission and the actual repeated transmission are the naming of the transmission mode when the repeated transmission under the type B is performed, the nominal repeated transmission can also be named as the standard repeated, normal repeated and the like, and the actual repeated transmission can also be named as the sub-repeated, segmented repeated and the like, and the naming manner of the nominal repeated transmission and the actual repeated transmission in the present application is not limited too much.

[0085] 2、SBFD symbol and non-SBFD symbol

[0086] In the frequency domain, the frequency domain resource on the SBFD symbol can contain the DL sub-band and the UL sub-band at the same time, such as the symbol in the actual repetition #0, the actual repetition #1 or the actual repetition #2 in FIG. 2. The frequency domain resource on the non-SBFD symbol does not contain the DL sub-band and the UL sub-band at the same time. The non-SBFD symbol can be a DL symbol, a UL symbol or a flexible (F) symbol, such as the symbol in the actual repetition #3 or the actual repetition #4 in FIG. 2. All the symbols in the multiple symbols contained in a time slot are SBFD symbols. Or, all the symbols in the multiple symbols contained in a time slot are non-SBFD symbols. Or, the multiple symbols contained in a time slot include at least one SBFD symbol and at least one non-SBFD symbol. As shown in FIG. 2, the time slot n contains the SBFD symbol and the non-SBFD symbol.

[0087] In some embodiments, there can also be a guard band (GB) between the DL sub-band and the UL sub-band. Through the guard band, the DL sub-band and the UL sub-band are isolated in the frequency domain to reduce the interference between the DL signal in the DL sub-band and the UL signal in the UL sub-band. On the SBFD symbol, the DL sub-band cannot be used for uplink transmission, the UL sub-band can be used for uplink transmission, and the GB can be used for uplink transmission; or, the DL sub-band cannot be used for uplink transmission, the UL sub-band can be used for uplink transmission, and the GB cannot be used for uplink transmission. On the UL symbol and the F symbol, the frequency domain range of the entire carrier component (CC) or uplink band width part (BWP) can be used for uplink transmission. On the DL symbol and the F symbol, the frequency domain range of the entire CC or BWP can be used for downlink transmission. It can be seen that the frequency domain range that can be used for uplink transmission in the SBFD symbol can be different from the frequency domain range that can be used for uplink transmission on the UL symbol and the F symbol.

[0088] In some embodiments, on the SBFD symbol, the frequency domain range that can be used for uplink transmission can be referred to as the uplink frequency domain range, and the frequency domain range that cannot be used for uplink transmission can be referred to as the non-uplink frequency domain range. For example, the uplink frequency domain range can be understood as the uplink frequency domain range on a CC or BWP.

[0089] 3. Transmit power of PUSCH

[0090] The transmit power of PUSCH can generally refer to the power used by the terminal when transmitting uplink signals through the PUSCH. The transmit power generally satisfies the following formula one:

[0091] Formula one is a formula defined in the relevant communication standard protocol, and here only the parameters involved in the case are briefly introduced. If there is any ambiguity, please refer to the relevant communication standard protocol for understanding. The parameters and parameter meanings not introduced can be referred to the relevant description in the relevant communication standard protocol, and will not be repeated here.

[0092] Optionally, the above formula one involves multiple power control parameters. The following briefly introduces several power control parameters in formula one for calculating the transmit power:

[0093] Power control parameter 1, P CMAX,f,c (i) is the maximum output power of the terminal at PUSCH transmission occasion i of carrier f of the serving cell c. Parameter i is the index of the PUSCH transmission time / transmission occasion.

[0094] Power control parameter 2, P O_PUSCH,b,f,c (j) is the reference transmit power of the terminal. It can include two parts: common configuration power P O_NOMINAL,PUSCH,f,c (j) and terminal-specific configuration power P O_UE_PUSCH,b,f,c (j), which can satisfy the following formula two:

[0095] P O_PUSCH,b,f,c (j) = P O_NOMINAL,PUSCH,f,c (j) + P O_UE_PUSCH,b,f,c (j)

[0096] When the configuration set index j is different, the terminal-specific configuration P O_UE_PUSCH,b,f,c (j) is different. The value of j can be any value in {0, 1, 2, 3, …, J-1}, and J is the number of configuration sets. J is an integer greater than or equal to 1.

[0097] 1) When the PUSCH power and path loss compensation parameter set (P0-PUSCH-AlphaSet) parameter is not configured, or the PUSCH is a random access response (Random Access Response, RAR) message scheduling uplink parameter, or message A (Message A, MSG A) PUSCH parameter, j = 0.

[0098] α b,f,c (j): If the msg3-Alpha (message 3-path loss compensation factor) parameter is configured by the high layer signaling, then αb,f,c (0) = msg3 - Alpha, otherwise a b,f,c (0) = 1.

[0099] 2) j = 1 for PUSCH transmission or repetition transmission configured by ConfiguredGrantConfig parameters. Repetition transmission is a semi-static scheduling transmission.

[0100] 3) j = 2 if Downlink Control Information format (DCI format) 0_0 or DCI format 0_1 does not contain SRS resource indicator (SRI) field, or no SRI-indicated PUSCH power control (SRI-PUSCH-PowerControl) signaling or parameters are configured.

[0101] 4) j ∈ {2, …, J-1} if the terminal is configured with more than 1 PUSCH power and path loss compensation parameter set identification (P0-PUSCH-AlphaSetId) values by SRI-PUSCH-PowerControl and DCI format 0_1 contains SRI field.

[0102] The possible values of P0 for PUSCH transmission or repetition transmission will be introduced as follows. O_UE_PUSCH,b,f,c (j).

[0103] R16 introduces an “open-loop power control parameter set indication” field in DCI, which can be used to indicate the available P0 values when no SRI-PUSCH-PowerControl signaling is configured or no ‘SRS resource indicator’ field is contained in DCI format 0_1. The indication of this “open-loop power control parameter set indication” is as follows:

[0104] When the value of this field is ‘0’ or ‘00’, the P0 value is equal to the first P0-PUSCH-AlphaSet in the signaling parameter P0-AlphaSet.

[0105] When the value of this field is ‘1’ or ‘01’, the P0 value is equal to the P0-PUSCH-Set corresponding to the first minimum P0-PUSCH-SetID in the signaling parameter P0-PUSCH-Set.

[0106] When the field value is '10', the P0 value is equal to the P0 corresponding to the second smallest P0-PUSCH-SetID in the signaling parameter P0-PUSCH-Set.

[0107] Power control parameter 3, PL b,f,c (q d ) is the uplink channel loss information. The terminal estimates the uplink channel loss information according to the reference signal. The reference signal used for the calculation of the uplink channel loss information can be SSB (Synchronization Signal Block) or CSI-RS (Channel Status Information-Reference Signal).

[0108] If the terminal is not configured with the PUSCH-PathlossReferenceRS parameter or before the terminal is configured with the dedicated higher layer parameter, the SSB (Synchronization Signal Block) used to obtain the master information block (MIB) is used as the reference signal to calculate the channel loss. If the PUSCH is scheduled by the RAR uplink grant message 3 (Msg3) or msg A PUSCH, the terminal uses the reference signal (RS) resource index q d The same as the reference signal used for PRACH transmission.

[0109] Optionally, the channel loss information PL b,f,c (q d ) can satisfy the following formula three:

[0110] PL b,f,c (q d ) = referenceSignalPower - higher layer filtered RSRP

[0111] Wherein, referenceSignalPower is a configured higher layer parameter, which can be referred to as a channel loss compensation parameter, and specifically can refer to the reference signal transmission power. higher layer filtered RSRP is a measurement parameter, which can be referred to as a channel loss reference signal power parameter, and specifically is the RSRP (Reference Signal Received Power) measured when sending the uplink channel, which is configured by the higher layer parameter QuantityConfig in the rrcReconfiguration signaling.

[0112] Power control parameter 4, is the number of resource blocks (RBs) allocated to the i-th PUSCH transmission occasion.

[0113] Power control parameter 5, Δ TF,b,f,c (i) is the MCS power adjustment amount, which can satisfy the following formula four:

[0114] When K s = 1.25, then

[0115] When K s = 0, then Δ TF,b,f,c (i) = 0

[0116] K s The value can be controlled by deltaMCS, and when deltaMCS is not present, K s = 0.

[0117] When K s = 1.25, BPRE and BPRE is the number of bits contained in each RE, reflecting the case where PUSCH carries UCI, the specific determination method is as follows:

[0118] 1) For uplink data, the following formula five is satisfied:

[0119] Where C is the number of code blocks, K r is the size of code block r, N RE is the number of REs, is the number of PRBs in the i-th PUSCH transmission occasion, is the number of PUSCH symbols per PRB in the transmission occasion i, is the number of REs excluding the REs occupied by DMRS and PTRS within the PUSCH symbol j, and it is assumed that there is no standard repeated segment in the case of PUSCH repetition type B, i.e. is the number of symbols for a nominal repeated transmission. As shown in FIG. 2, the number of symbols for a nominal repeated transmission is 14.

[0120] When PUSCH contains uplink data

[0121] 2) For CSI (Channel Status Information) transmission without uplink data, the following formula six is satisfied:

[0122] where Qm is the modulation order, R is the target code rate, described in TS 38.214. These parameters are provided in the DCI.

[0123] When PUSCH contains only CSI without uplink data The specific value of n can be determined according to Table 9.3-2 in the standard protocol TS 38.213.

[0124] Power control parameter 6, f b,f,c (i, l) is a closed loop parameter, the specific content of which can be referred to the description of the relevant standard, which is not described here.

[0125] 4. Frequency hopping

[0126] PUSCH repetition type B supports two frequency hopping modes, which are: inter-repetition frequency hopping and inter-slot frequency hopping. When the terminal uses inter-repetition frequency hopping, the frequency hopping is performed between adjacent two nominal repetition transmissions, and the actual repetition transmissions within a nominal repetition transmission do not hop.

[0127] In the case of inter-repetition frequency hopping, the starting RB of any actual repetition transmission within the nth nominal repetition transmission can satisfy the following formula seven:

[0128] where RB start (n) is the index of the starting RB of any actual repetition transmission within the nth nominal repetition transmission, RB start is the index of the starting RB of the first actual repetition transmission of the preset nominal repetition transmission, and RB offset is the frequency offset of the RB between adjacent two frequency hops.

[0129] 5. Association of two SRS resource sets and nominal repetition transmission should be understood that for repetition type A, if two SRS resource sets are configured and any one SRS resource set can be configured as "codebook" or "non-codebook", the association mode of the two SRS resource sets and the PUSCH is as follows: in the case of K greater than 1, the same symbol allocation mode is used on K consecutive slots, and the PUSCH is limited to single-layer data stream transmission. K is the number of consecutive slots corresponding to multiple nominal repetition transmissions.

[0130] For example, time slot 1-time slot 6 in FIG. 1 are 6 consecutive slots, and the value of K is 6. Seven nominal repetition transmissions can be performed in the 6 consecutive slots of time slot 1-time slot 6.

[0131] Of course, the correspondence between the nominal repeated transmission and the time slot shown in FIG. 1 is only exemplary, and each time slot can also perform an independent nominal repeated transmission, that is, the duration of the nominal repeated transmission can be one time slot.

[0132] It should also be understood that for repetition type B, if two SRS resource sets are configured and any one SRS resource set can be configured as "codebook" or "non-codebook", the PUSCH nominal repeated transmission is associated with the SRS resource set.

[0133] In the case of one nominal repeated transmission of one time slot, the association of the first and second SRS resource sets with the K time slots in the existing communication standard is as follows:

[0134] Method 1, DCI format 0_3 schedules PUSCH, the first SRS resource set is associated with all K consecutive time slots.

The third slot refers to the slot adjacent to the second slot after the second slot. The fourth slot refers to the slot adjacent to the third slot after the third slot.

[0152] 6、Unusable symbol

[0153] The unusable symbol can refer to a symbol that cannot be used in a communication system. Various unusable symbols are specified in current communication standards, such as a downlink symbol configured by high layer signaling, a SSB symbol, a CORESET symbol configured by MIB signaling or SIB1 message, a symbol interval after a downlink symbol configured by high layer signaling, an invalid symbol configured by high layer signaling, a symbol located at a slot boundary, etc.

[0154] The network device can configure the unusable symbol to the terminal through signaling. The signaling is, for example, high layer signaling / parameters, MIB signaling or SIB1 message, etc. Specifically, the network device can carry the position information of the unusable symbol in the signaling, and the terminal determines the unusable symbol through the position information of the unusable symbol. The position information of the unusable symbol can include, for example, the position of the symbol in the slot, the period of transmission or repeated transmission, and / or the symbol position offset, etc.

[0155] The symbol position can be determined according to the period of transmission or repeated transmission, in combination with the position of the symbol in the slot or the symbol position offset. The symbol located at the symbol position can be the unusable symbol.

[0156] For example, the terminal can be configured with a high layer parameter invalidSymbolPattern, which provides a symbol-level bitmap across one or two slots. A bit value in the symbol-level bitmap represents whether the symbol at the position is unusable. For example, a bit value of 1 represents that the symbol at the position is unusable, and a bit value of 0 represents that the symbol at the position is usable. The usable symbol refers to a symbol that can be used in a communication system. The position information of the unusable symbol is, for example, the position of the symbol with a bit value of 1 in the symbol-level bitmap.

[0157] For example, the terminal can configure the unavailable symbol using a time domain pattern. The unavailable symbol configured by the time domain pattern is the unavailable symbol configured by the location information. Taking the high layer parameter: periodicityAndPattern given by invalidSymbolPattern as an example, each bit of periodicityAndPattern can be associated with a time unit corresponding to each symbol in the symbol-level bitmap, and the bit value equal to 1 indicates that the symbol-level bitmap symbol exists in the time unit.

[0158] PeriodicityAndPattern can be valued from the following set: {1, 2, 4, 5, 8, 10, 20, or 40}, and the time unit of the set is millisecond. Assuming that the time unit of each symbol is 4 milliseconds, there are 10 symbols in a period. As P represents the period, P is the time duration of periodicityAndPattern in millisecond.

[0164] In order to improve uplink coverage and throughput, a sub-band non-overlapping full duplex (SBFD) scheme is introduced in a time division duplex (TDD) system to support SBFD. The TDD system supporting SBFD can also be referred to as an SBFD system. In the SBFD system, a time slot can contain SBFD symbols and / or non-SBFD symbols. Currently, in the SBFD system, how to implement PUSCH transmission in repetition type B is a technical problem to be solved.

[0165] To solve the above technical problems, the embodiment of the present application provides a communication method, a terminal can receive transmission configuration information of an uplink channel, the transmission configuration information can include at least one of the following: a first power, a second power, frequency hopping information, unavailable symbols, or an SRS resource set, wherein the first power refers to the transmission power of the uplink channel, and the second power refers to the transmission power of the uplink channel in repeated transmission, so as to perform transmission of the uplink channel according to the transmission configuration information. In the process of transmission of the uplink channel, effective transmission is performed according to the transmission configuration information, the transmission failure phenomenon caused by unclear transmission configuration information is reduced, and the uplink transmission performance is improved.

[0166] In the following, the technical solutions shown in the present application are described in detail through specific embodiments. It should be noted that the following embodiments can exist independently, or can be combined with each other. For the same or similar content, it is not repeated in different embodiments.

[0167] Embodiment 1, the embodiment of the present application provides a communication method, as shown in the flow chart of the communication method of FIG. 4, the method comprises:

[0168] S401, the network device sends transmission configuration information of an uplink channel to a terminal, and correspondingly, the terminal receives the transmission configuration information of the uplink channel. The transmission configuration information includes at least one of the following: a first power, a second power, frequency hopping information, unavailable symbols, or an SRS resource set, the first power refers to the transmission power of the uplink channel, and the second power refers to the transmission power of the uplink channel in repeated transmission.

[0169] In some embodiments, the communication method provided by the embodiment of the present application can be executed by a terminal, or also can be executed by a component (such as a chip or a circuit) configured in the terminal. The present application does not limit this.

[0170] Optionally, the network device can send transmission configuration information at least once. The information of each transmission configuration information sent each time can be the same or different, and the embodiment does not limit this too much.

[0171] It can be understood that in the case of sending multiple transmission configuration information, if an item of information in the transmission configuration information is sent multiple times, any one of them can be selected, for example, the item of information in the earliest sent transmission configuration information can be selected, or the item of information in the last sent transmission configuration information can be selected.

[0172] Exemplarily, the first power is transmitted twice, the first power is contained in the transmission configuration information of the first transmission, and the first power is still contained in the transmission configuration information of the second transmission. When the terminal determines the first power, the first power in the transmission configuration information of the first transmission can be used, or the first power in the transmission configuration information of the second transmission can be used. The uplink channel can be any one of a PUSCH, a physical uplink control channel (PUCCH), a physical random access channel (PRACH), or any other type of uplink channel, and the specific type of the uplink channel is not limited in the embodiment.

[0173] Optionally, the transmission configuration information can include some basic parameters, which can be used for transmission of signals on the uplink channel. For example, the first power, the second power, frequency hopping information, at least one of the unavailable symbols, or the SRS resource set. The terminal can transmit data on the uplink channel according to the configuration of the transmission configuration information.

[0174] It should be noted that the transmission configuration information is only the name of the parameter configuration function, and in actual application, the transmission configuration information can also be referred to as transmission information, configuration information, channel configuration information, channel information, transmission configuration information, transmission information, etc. The name of the transmission configuration information is not limited in the embodiment.

[0175] In some embodiments, the first power refers to the transmission power of the uplink channel when performing any transmission. The transmission type can include a non-repetition transmission type or a repetition type A or a repetition type B, for example. The non-repetition transmission can be a single transmission, for example.

[0176] In some embodiments, in the case of performing a non-repetition transmission using the first power (i.e., the first power is the transmission power corresponding to the non-repetition transmission), a repetition transmission is performed using the second power. The repetition transmission can be a repetition type B repetition transmission and / or a repetition type A repetition transmission, for example (i.e., the second power is the transmission power corresponding to the repetition type B repetition transmission and / or the repetition type A repetition transmission).

[0177] In some embodiments, in the case of performing a repetition type A repetition transmission or a non-repetition transmission using the first power (i.e., the first power is the transmission power corresponding to the repetition type A repetition transmission or the non-repetition transmission), a repetition type B repetition transmission is performed using the second power (i.e., the second power is the transmission power corresponding to the repetition type B repetition transmission).

[0178] In some embodiments, the first power is used for performing the repetition transmission of repetition type A or the non-repetition transmission, and the second power is used for performing the repetition transmission of repetition type B.

[0179] For convenience of description, the following description is taken as an example of using the first power to perform the repetition transmission of repetition type A or the non-repetition transmission, and using the second power to perform the repetition transmission of repetition type B. Other cases can be understood with reference to this case.

[0180] In some embodiments, the transmission power of the uplink channel satisfies the above formula one, and the formula one involves the power control parameter 4 in the calculation:

[0181] In the related art, the value of the power control parameter 4 is the number of RBs allocated to the i-th transmission occasion, that is, the total number of RBs allocated to the transmission occasion i. Different from the existing calculation method, in the present application, the first power in the calculation process, the above-mentioned power control parameter 4: is the number of PRBs corresponding to the UL available PRBs.

[0182] It should be understood that the first power can refer to the power of the uplink transmission when the uplink transmission is performed at the transmission occasion i, which is the power calculated using the number of PRBs corresponding to the UL available PRBs.

[0183] Optionally, the nominal repetition transmission of repetition type B includes the first type of repetition transmission and / or the second type of repetition transmission. The first type of repetition transmission refers to the actual repetition transmission in the SBFD symbol. The second type of repetition transmission refers to the actual repetition transmission in the non-SBFD symbol.

[0184] In some embodiments, in the case of using the second power to perform the repetition transmission of repetition type B, the second power can include a first transmission power and / or a second transmission power. The first transmission power refers to the power of the first type of repetition transmission, and the second transmission power refers to the power of the second type of repetition transmission. That is, the actual repetition transmission in the SBFD symbol uses the first transmission power, and the actual repetition transmission in the non-SBFD symbol uses the second transmission power.

[0185] In the related art, the transmission of the uplink channel can refer to the transmission of the uplink channel at a transmission occasion i. The transmission occasion i refers to a time unit for transmitting a PUCCH / PUSCH / SRS / PRACH. The time unit can be a slot, a symbol, a mini-slot, a subframe, etc., which is not limited in the present application. For convenience of description, the time unit is taken as a slot in the present application for description. The transmission power of the uplink channel at the transmission occasion i can satisfy formula one.

[0186] As described above, the parameter P2 in the formula one calculation process involves a parameter O_PUSCH,b,f,c (j), the parameter involved in the MCS power adjustment amount in the parameter P5 and / or a parameter PL, which is a path loss information b,f,c (q d ) and the like.

[0187] In some embodiments, the second power in the embodiments of the present application refers to improving the above parameters according to the transmission under different symbol types, and inputting the improved parameters into the power obtained by formula one calculation.

[0188] As in the conventional calculation scheme, the same initial power is used for transmission under different symbol types, that is, the parameter P2 in the parameter P5 O_PUSCH,b,f,c (j) uses the same initial power in SBFD symbols or non-SBFD symbols.

[0189] In the technical scheme of the present application, different initial powers are used for transmission under different symbol types. That is, the parameter P2 in the parameter P5 O_PUSCH,b,f,c (j) uses different initial powers in SBFD symbols or non-SBFD symbols. For example, a first initial power is used in SBFD symbols, and a second initial power is used in non-SBFD symbols.

[0190] For example, in the conventional calculation scheme, the parameter involved in the MCS power adjustment amount in the parameter P5 The parameter takes the number of PUSCH symbols of the transmission occasion i in each RB as the value.

[0191] In the technical scheme of the present application, the number of PUSCH symbols of the transmission occasion i in each RB is different under different symbol types. For example, a first symbol number is used in SBFD symbols, and a second symbol number is used in non-SBFD symbols.

[0192] In some embodiments, the path loss information of the uplink channel can refer to the difference between the transmission power on the terminal side and the reception power on the network side.

[0193] The frequency hopping information refers to the parameters related to frequency hopping configured in the communication system when supporting frequency hopping transmission. For example, the frequency hopping information can include an RB offset RB offsetIn addition, the starting RBRB start may be obtained by high layer signaling or DCI indication. Referring to Equation Seven, the starting RB and the RB offset can be calculated to obtain the target RB.

[0194] When performing frequency hopping transmission, the starting position of the frequency domain resource of each transmission can be the starting RB or the target RB. For any transmission performed on the uplink channel, the frequency domain resource used by this transmission is different from the frequency domain resource used by the previous or subsequent transmission.

[0195] For example, the starting position of the frequency domain resource of the first nominal repeated transmission can be the starting RB, the starting position of the frequency domain resource of the second nominal repeated transmission can be the target RB, the starting position of the frequency domain resource of the third nominal repeated transmission can be the starting RB, the starting position of the frequency domain resource of the fourth nominal repeated transmission can be the target RB, and so on.

[0196] It can be understood that the frequency hopping transmission can include inter-repetition frequency hopping or inter-slot frequency hopping. Inter-repetition frequency hopping refers to that when performing repeated transmission, the frequencies of two adjacent repeated transmissions are different. Inter-slot frequency hopping refers to that the frequencies of transmissions of two adjacent slots are different.

[0197] wherein the unavailable symbol can refer to a symbol that cannot be used in the communication system.

[0198] wherein the transmission configuration information can include one or more SRS resource sets. The one or more SRS resource sets can be configured as “codebook” or “non-codebook”.

[0199] The SRS resource set can be a collection of a set of SRS resources, which are applied to specific time-frequency resources, for channel state information acquisition and beam management of uplink.

[0200] Further, the one or more SRS resource sets can be associated with nominal repeated transmission.

[0201] S402, the terminal performs transmission of the uplink channel according to the transmission configuration information.

[0202] In some embodiments, the transmission of the uplink channel includes non-repeated transmission or repeated transmission. The transmission of the uplink channel can include one or more times. The non-repeated transmission can also be referred to as one-time transmission or ordinary transmission.

[0203] In some embodiments, step 402 can include performing nominal repeated transmission of the uplink channel according to the transmission configuration information. The nominal repeated transmission can include one or more times. In some embodiments, step 402 can include performing a plurality of actual repeated transmissions corresponding to the nominal repeated transmission of the uplink channel according to the transmission configuration information.

[0204] Optionally, before performing step 402, the terminal is further configured to: start / activate the repeated transmission. In the case of starting / activating the repeated transmission, the nominal repeated transmission of the uplink signal is performed according to the transmission configuration information.

[0205] Optionally, the network device, such as a base station, can inform the terminal to start / activate the repeated transmission. Specifically, the network device can inform the terminal to start / activate the repeated transmission through one or more bits of configuration information. For example, the configuration information is “1” which means to start / activate the repeated transmission. The configuration information is “0” which means to close / deactivate the repeated transmission or to start / activate the non-repeated transmission.

[0206] In the above embodiments, the first power and / or the second power can be used to determine the transmit power of the terminal, the frequency hopping information can be used to determine the frequency domain resource of the frequency hopping transmission of the terminal, the unavailable symbol can be used to determine the time domain resource of the transmission of the terminal, and the SRS resource set can be used to determine the antenna and beam used for the transmission of the terminal.

[0207] The following describes several possible execution manners of the transmission of the uplink channel in step 402.

[0208] Manner 1: The transmission configuration information includes the first power, and the transmission of the uplink channel is performed with the first power as the transmit power.

[0209] Since the first power is the transmit power corresponding to the repeated transmission of the repetition type A or the non-repeated transmission, when the terminal needs to perform the repeated transmission of the repetition type A or the non-repeated transmission, the first power can be used as the transmit power for transmission.

[0210] Manner 2: The transmission configuration information includes the second power, and the repeated transmission of the uplink channel is performed with the second power as the transmit power.

[0211] Since the second power is the transmit power corresponding to the repeated transmission of the repetition type B, when the terminal needs to perform the repeated transmission of the repetition type B, the second power can be used as the transmit power for transmission.

[0212] In some embodiments, the repeated transmission is actually divided into multiple actual repeated transmissions, and performing the repeated transmission of the uplink channel with the second power as the transmit power can mean performing each actual repeated transmission of the uplink channel with the second power as the transmit power.

[0213] Manner 3, the transmission configuration information includes a first power and a second power, since the first power is the transmission power corresponding to the repetition transmission of repetition type A or the non-repetition transmission, when the terminal needs to perform the repetition transmission of repetition type A or the non-repetition transmission, the first power can be used as the transmission power for transmission, since the second power is the transmission power corresponding to the repetition transmission of repetition type B, when the terminal needs to perform the repetition transmission of repetition type B, the second power can be used as the transmission power for transmission.

[0214] Manner 4, the transmission configuration information includes frequency hopping information, then according to the frequency hopping information, the frequency hopping transmission of the uplink channel is performed. Wherein, the frequency hopping information can include RB offset RB offset In addition, the starting RB RB start Can be obtained by high layer signaling or DCI indication. Referring to formula seven, the starting RB and the RB offset can be calculated to obtain the target RB. According to the frequency hopping information, the frequency hopping transmission of the uplink channel can include: according to the frequency hopping information, determining the starting RB and the target RB. For any transmission of the uplink channel, such as nominal repetition transmission, the starting RB or the target RB can be used as the starting position of the frequency domain resource of this transmission.

[0215] For example, for the nominal repetition transmission with odd transmission times, the starting RB can be used as the starting position of the frequency domain resource of this transmission. For the nominal repetition transmission with even transmission times, the target RB can be used as the starting position of the frequency domain resource of this transmission.

[0216] Manner 5, the transmission configuration information includes unavailable symbols, when performing the nominal repetition transmission of the uplink channel, the nominal repetition transmission includes a plurality of actual repetition transmissions, and there are unavailable symbols contained in the transmission configuration information between the plurality of actual repetition transmissions. The unavailable symbol is used to determine the time domain resource of the actual repetition transmission.

[0217] Manner 6, the transmission configuration information includes SRS resource set, then the nominal repetition transmission is performed on the nominal repetition transmission associated with the SRS resource set. The nominal repetition transmission can be segmented into a plurality of actual repetition transmissions.

[0218] For example, the SRS resource set can include a first SRS resource set and a second SRS resource set.

[0219] As an embodiment, in the case of non-segmentation of nominal repeated transmission, the first SRS resource set is applied to the nominal repeated transmission in SBFD symbols, the antenna or beam is selected for the nominal repeated transmission according to the first SRS resource set, and the nominal repeated transmission is performed using the selected antenna and beam. The second SRS resource set is applied to the nominal repeated transmission in non-SBFD symbols, the antenna or beam is selected for the nominal repeated transmission according to the second SRS resource set, and the nominal repeated transmission is performed using the selected antenna and beam.

[0220] As an embodiment, in the case of non-segmentation of nominal repeated transmission, the second SRS resource set is applied to the nominal repeated transmission in SBFD symbols, the antenna or beam is selected for the nominal repeated transmission according to the second SRS resource set, and the nominal repeated transmission is performed using the selected antenna and beam. The first SRS resource set is applied to the nominal repeated transmission in non-SBFD symbols, the antenna or beam is selected for the nominal repeated transmission according to the first SRS resource set, and the nominal repeated transmission is performed using the selected antenna and beam.

[0221] As an embodiment, in the case of segmentation of nominal repeated transmission into multiple actual repeated transmissions, the transmission of each actual repeated transmission is as follows:

[0222] In the case of application of the first SRS resource set to the actual repeated transmission in SBFD symbols, the antenna and beam are selected for the actual repeated transmission according to the first SRS resource set, and the actual repeated transmission is performed using the selected antenna and beam; in the case of application of the second SRS resource set to the actual repeated transmission in non-SBFD symbols, the antenna and beam are selected for the actual repeated transmission according to the second SRS resource set, and the actual repeated transmission is performed using the selected antenna and beam.

[0223] Alternatively, in the case of application of the second SRS resource set to the actual repeated transmission in SBFD symbols, the antenna and beam are selected for the actual repeated transmission according to the second SRS resource set, and the actual repeated transmission is performed using the selected antenna and beam; in the case of application of the first SRS resource set to the actual repeated transmission in non-SBFD symbols, the antenna and beam are selected for the actual repeated transmission according to the first SRS resource set, and the actual repeated transmission is performed using the selected antenna and beam.

[0224] Of course, the above execution modes 1-6 only list the implementation mode in which the transmission configuration information includes one or two of the first power, the second power, the frequency hopping information, the unavailable symbol, or the SRS resource set, and in actual application, the above configuration information can be used in combination.

[0225] When the transmission configuration information includes the first power, the second power, the frequency hopping information, the unavailable symbol and the SRS resource set according to the manner 7, the nominal repeated transmission of the uplink channel is performed according to the first power, the second power, the frequency hopping information, the unavailable symbol and the SRS resource set.

[0226] For example, performing the nominal repeated transmission of the uplink channel according to the first power, the second power, the frequency hopping information, the unavailable symbol and the SRS resource set can include the following steps S1-S2.

[0227] S1, for the non-repeated transmission or the nominal repeated transmission of the repetition type A, the first power is used as the transmission power. For the nominal repeated transmission of the repetition type B, the second power is used as the transmission power.

[0228] S2, the target RB is calculated according to the RB offset and the starting RB in the frequency hopping information. When the uplink channel performs the frequency hopping transmission, the starting RB or the starting position of the frequency domain resource of this transmission can be the starting position of the frequency domain resource of this transmission, and the starting position of the frequency domain resource of this transmission is different from the starting position of the frequency domain resource of the previous transmission or the next transmission. According to the unavailable symbol, the time domain resource of the uplink channel is determined. The antenna and the beam for the nominal repeated transmission are selected through the SRS resource set.

[0229] Then, the selected antenna and the beam are used to transmit the signal corresponding to the nominal repeated transmission on the determined frequency domain resource and time domain resource with the first power or the second power as the transmission power.

[0230] The embodiment of the present application provides a communication method. A terminal can receive transmission configuration information of an uplink channel. The transmission configuration information can include at least one of the following: a first power, a second power, frequency hopping information, an unavailable symbol or an SRS resource set. The first power refers to the transmission power of the uplink channel, and the second power refers to the transmission power of the uplink channel in repeated transmission. The transmission of the uplink channel is performed according to the transmission configuration information. In the process of the transmission of the uplink channel, effective transmission is performed according to the transmission configuration information, the transmission failure phenomenon caused by unclear transmission configuration information is reduced, and the uplink transmission performance is improved.

[0231] In some embodiments, the communication method of the present application further includes receiving indication information. The indication information is used to indicate the transmission configuration information of the uplink channel.

[0232] Exemplarily, the execution subject of the communication method provided by the present application is a terminal or a component in the terminal, and the terminal receives the indication information. The execution subject of the communication method of the present application is a network device or a component in the network device, and the network device sends the indication information.

[0234] S501, the network device sends indication information, and correspondingly, the terminal receives the indication information.

[0235] The indication information is used to indicate transmission configuration information of the uplink channel, and the transmission configuration information comprises at least one of the following: a first power, a second power, frequency hopping information, unavailable symbols, or a SRS resource set. The first power refers to the transmission power of the uplink channel, and the second power refers to the transmission power of the uplink channel in repeated transmission.

[0236] It should be understood that the indication information can comprise at least one. Therefore, step 501 can comprise: the network device sends at least one indication information, and the terminal receives the at least one indication information. Each indication information is used to indicate one or more of the transmission configuration information. The at least one indication information can be sent in sequence or simultaneously. In the embodiment, the sending order or sending time of different indication information is not limited too much.

[0237] For example, taking the sending of two indication information as an example, the first indication information can indicate at least one of the first power or the second power, and the second indication information can indicate at least one of the frequency hopping information, the unavailable symbols, or the two SRS resource sets.

[0238] Of course, the number of indication information, the type and number of each indication information indicating the transmission configuration information are not the focus of the present application, and can be determined according to the actual configuration scene or demand. In the embodiment, this is not limited too much.

[0239] It should be understood that in some embodiments, after the terminal receives the indication information, the method can further comprise:

[0240] The terminal can determine the transmission configuration information indicated by the indication information.

[0241] The indication of the transmission configuration information of the uplink channel by the indication information can comprise the following several indication modes:

[0242] Mode 1: the indication information comprises the transmission configuration information of the uplink channel.

[0243] Mode 2: the indication information comprises configuration information used to determine the transmission configuration information of the uplink channel.

[0244] The configuration information can be a parameter used to determine the transmission configuration information.

[0245] For example, the configuration information can include at least one of the following: the first PRB quantity, the first power control parameter or the first transmission power, the second power control parameter or the second transmission power, the first index and / or the second index, the unavailable symbol, the two configured SRS resource sets, or the association manner of the time slot of the uplink channel and the two SRS resource sets, and the like. The meanings of the first power control parameter, the first transmission power, the second power control parameter, the second transmission power, the first index, and the second index can be referred to below.

[0246] S502, the terminal performs transmission of the uplink channel according to the transmission configuration information indicated by the indication information.

[0247] In this embodiment, some steps are the same as those in the foregoing embodiments, and will not be described here.

[0248] In the embodiments of the present application, the network device sends the indication information of the transmission configuration information to the terminal, so that the terminal determines the transmission configuration information indicated by the indication information, and then performs transmission of the uplink channel by using the transmission configuration information, thereby realizing the transmission of the uplink channel by the terminal, and through the configuration of the transmission configuration information, the effective transmission is performed in the process of the transmission of the uplink channel, the transmission failure phenomenon caused by the unclear transmission configuration information is reduced, and the uplink transmission performance is improved.

[0249] The indication information indicates the transmission configuration information in detail.

[0250] In the display indication mode, the specific parameters contained in the indication information can include but are not limited to the transmission configuration information of the uplink channel. For example, the indication information can be information in radio resource control (RRC) signaling or downlink control information (DCI), that is, the field in the RRC signaling or DCI signaling carries the "transmission configuration information of the uplink channel".

[0251] Further, the terminal can receive the indication information. The transmission configuration information of the uplink channel is read from the indication information.

[0252] The indication information can be one or more. Taking the transmission configuration information as the first power and the unavailable symbol as an example, two indication information can be used to indicate the first power and the unavailable symbol respectively. For example, the RRC signaling can indicate the "first power", and the DCI signaling can indicate the "unavailable symbol".

[0253] For example, the preset field in the RRC signaling can carry the "first power". The preset field in the DCI signaling can carry the "unavailable symbol". The preset field can be a newly added field in the signaling or a multiplexed existing field in the signaling.

[0254] When one or more of the transmission configuration information is carried in the preset field, it can specifically mean that the transmission configuration information itself is directly carried in the preset field, or it can mean that the indication information used to indicate the transmission configuration information is carried in the preset field. Taking the first power as an example, the value of the first power can be directly carried in the preset field, or the parameters used to calculate the first power can be carried in the preset field. Taking the unusable symbol as an example, the symbol type of the unusable symbol can be directly carried in the preset field, or the indication information used to indicate the unusable symbol can be carried in the preset field.

[0255] In the implicit indication mode, the preset field in the RRC signaling and / or the DCI signaling can be default, and then in the case of default of the preset field, the transmission configuration information configured by the terminal is used. In this case, before step 401, the terminal is configured with the transmission configuration information.

[0256] It can also be understood that the indication information can include multiple. For example, there are two indication information, which are indication information 1 and indication information 2. The indication information 1 and the indication information 2 can be carried in the same signaling or different signaling. For example, the RRC signaling can carry the indication information 1 and the indication information 2 at the same time. Or, the first RRC signaling can carry the indication information 1, and the second RRC signaling can carry the indication information 2. Or, the RRC signaling can carry the indication information 1, and the DCI signaling can carry the indication information 2. The signaling carrying mode of multiple indication information in the embodiment is not limited too much.

[0257] In the embodiment of the application, the transmission configuration information of the uplink channel is realized by the indication of the indication information, which can make the transmission configuration information of the uplink channel more accurate and effective, and can realize more effective and stable uplink transmission.

[0258] The process of "performing transmission of the uplink channel" is introduced below in three cases:

[0259] The first case is to perform transmission of the uplink channel in the SBFD symbol.

[0260] In this case, the transmission of the uplink channel uses the SBFD symbol. For example, nominal repetition #0 shown in FIG. 2, each SBFD symbol contains a DL subband and a UL subband.

[0261] Optionally, the uplink channel is, for example, PUSCH. The nominal repeated transmission of PUSCH is performed in the SBFD symbol.

[0262] The time unit can be a basic unit of measuring time. For example, the time unit can be any one of the following: frame, subframe, slot, symbol.

[0263] The transmission of the uplink channel can comprise a nominal repetition transmission of the uplink channel. The nominal repetition transmission of the uplink channel can refer to one standard repetition transmission of the PUSCH.

[0264] In the second case, the transmission of the uplink channel is performed in non-SBFD symbols.

[0265] Optionally, the uplink channel is, for example, a PUSCH. The nominal repetition transmission of the PUSCH is performed in non-SBFD symbols.

[0266] In the third case, the transmission of the uplink channel is performed in SBFD symbols and non-SBFD symbols.

[0267] It should be understood that the transmission of the uplink channel in SBFD symbols and non-SBFD symbols can comprise performing a nominal repetition transmission of the uplink channel. The nominal repetition transmission can comprise actual repetition transmissions in SBFD symbols and actual repetition transmissions in non-SBFD symbols.

[0268] It should be understood that performing a nominal repetition transmission of the uplink channel in SBFD symbols and non-SBFD symbols can also be described as performing a nominal repetition transmission of the uplink channel across SBFD symbols and non-SBFD symbols.

[0269] Optionally, when the transmission of the uplink channel is a nominal repetition transmission, in the case of performing a nominal repetition transmission of the uplink channel in SBFD symbols and non-SBFD symbols, one nominal repetition transmission of the uplink channel is split into multiple actual repetition transmissions. Some actual repetition transmissions are transmitted in SBFD symbols, the actual repetition transmissions in SBFD symbols can be referred to as first actual repetition transmissions, and some actual repetition transmissions are transmitted in non-SBFD symbols, the actual repetition transmissions in non-SBFD symbols can be referred to as second actual repetition transmissions. As shown in nominal repetition #1 of FIG. 2, actual repetition #2 is transmitted in SBFD symbols, and actual repetition #3 and actual repetition #4 are transmitted in non-SBFD symbols.

[0270] Optionally, performing a nominal repetition transmission of the uplink channel in SBFD symbols and non-SBFD symbols can comprise transmitting a first actual repetition transmission of the PUSCH in SBFD symbols and transmitting a second actual repetition transmission of the PUSCH in non-SBFD symbols.

[0271] In the embodiments of the present application, when the terminal transmits data using the uplink channel, the sub-band full-duplex technology and / or the non-full-duplex technology are supported, so that the uplink and downlink channels can realize reliable and stable data transmission in different frequency bands and bandwidths, have strong adaptability, and enrich the application scenarios.

[0272] In some embodiments, the first power can be obtained based on the first PRB number, and the first PRB number refers to the PRB number corresponding to the UL available PRB.

[0273] In this embodiment, the terminal or network device can also be configured to calculate the first power based on the first PRB quantity.

[0274] The calculation formula of the first power can satisfy Formula One. In the calculation process of Formula One, parameters such as power control parameters 1-6 are involved. Among them, the power control parameter 4 is: the first PRB quantity.

[0275] In some embodiments, in the case where the uplink frequency domain range is known, the uplink channel transmission can be performed using the uplink frequency domain range. In the process of transmitting the uplink channel, the UL sub-band frequency resource activated in the UL BWP is referred to as the UL usable PRB. The DL sub-band frequency resource activated in the DL BWP is referred to as the DL usable PRB.

[0276] Optionally, the UL usable PRB can refer to the UL sub-band frequency resource activated in the UL BWP. The UL un-usable PRB refers to the resource other than the UL sub-band frequency resource activated in the UL BWP. The first PRB quantity can refer to the number of resource blocks of the UL sub-band frequency resource activated in the UL BWP.

[0277] In some embodiments, in the case where the uplink channel is PUSCH, the terminal can also determine a second PRB quantity. The second PRB quantity can refer to the number of UL un-usable PRBs, and then calculate the first PRB quantity according to the total number of UL PRBs and the second PRB quantity.

[0278] In some embodiments, in the case where the uplink channel is PUSCH, the first PRB quantity can refer to the PRB quantity corresponding to the usable PRB in a PUSCH or in a BWP. The second PRB quantity can refer to the PRB quantity corresponding to the un-usable PRB in a PUSCH or in a BWP.

[0279] In some embodiments, for the PRB in the BWP, the PRB can also be divided into UL usable PRB and UL un-usable PRB. Therefore, for the first power of the UL BWP, the first PRB quantity involved in the calculation process of the first power can refer to the PRB quantity corresponding to the usable PRB in the BWP, or the second PRB quantity can refer to the PRB quantity corresponding to the usable PRB in the BWP.

[0280] As shown in the resource distribution example diagram of FIG. 6, there are resources RBG0-RBG7, where RBG0, 1, 2, 6 and 7 are DL subbands, and RBG3, 4 and 5 are UL subbands. The PUSCH allocated resources are RBG3 and RBG4, where part of RBG3 is in the uplink (UL) subband and part is outside the UL subband, i.e., in the downlink (DL) subband. For the uplink channel, the PRBs located in the UL subband are the available PRBs for the uplink channel, and thus the number of UL usable PRBs in the actually allocated RBG3 and RBG4 is PRB12-18, i.e., the first PRB number = 7. That is, in the first power calculation process described above, The value is 7.

[0281] In the embodiments of the present application, the number of PRBs corresponding to the uplink available PRBs is used to calculate the first power, i.e., the number of PRBs corresponding to the uplink available PRBs is actually used in the first power calculation process, so that the first PRB number corresponding to the actually used PRBs participates in the first power calculation process, which helps to determine the actual transmission power according to the actual transmission bandwidth, and effectively improves the anti-interference capability of the uplink signal.

[0282] In some embodiments, at a cross-slot or uplink-downlink switching point, the nominal repeated transmission can be segmented into at least one actual repeated transmission.

[0283] The cross-slot can mean that the nominal repeated transmission is performed in two or more adjacent slots, i.e., part of the actual repeated transmissions of the nominal repeated transmission are located in the first slot, and part of the actual repeated transmissions of the nominal repeated transmission are located in the slots other than the first slot.

[0284] The uplink-downlink switching point can mean a time point or slot at which uplink transmission and downlink transmission are switched. For example, a flexible slot located between an uplink slot and a downlink slot can be used as an uplink-downlink switching point. The flexible slot can also be referred to as a special slot. The uplink slot can mean a slot used for uplink transmission, and the downlink slot can mean a slot used for downlink transmission.

[0285] On the basis of a time division duplexing (TDD) system supporting SBFD, the transmission of the uplink channel includes a nominal repeated transmission, and the nominal repeated transmission of the uplink channel includes:

[0286] The first type of repeated transmission, i.e., the actual repeated transmission in the SBFD symbol;

[0287] And / or the second type of repeated transmission, i.e., the actual repeated transmission in the non-SBFD symbol.

[0288] Optionally, the actual repeated transmission refers to a segment of the nominal repeated transmission. The nominal repeated transmission is segmented into at least one actual repeated transmission according to a symbol type. The symbol type may, for example, be an SBFD symbol type or a non-SBFD symbol type. Each actual repeated transmission may be either a first type of repeated transmission or a second type of repeated transmission.

[0289] The repetition type of the nominal repeated transmission may be a repetition type A or a repetition type B.

[0290] Further, the symbol of the first type of repeated transmission belongs to an SBFD symbol type. The symbol of the second type of repeated transmission belongs to a non-SBFD symbol type.

[0291] Further, the communication method provided in the present application may include at least one of the following:

[0292] performing actual repeated transmission of the uplink channel in an SBFD symbol;

[0293] performing actual repeated transmission of the uplink channel in a non-SBFD symbol.

[0294] It should be understood that the number of transmissions of the actual repeated transmission performed in the SBFD symbol may be 0, 1 or multiple times. The number of transmissions of the actual repeated transmission of the uplink channel performed in the non-SBFD symbol may be 0, 1 or multiple times.

[0295] Exemplarily, the terminal may perform 0, 1 or multiple times of actual repeated transmission of the uplink channel in the SBFD symbol; and / or perform 0, 1 or multiple times of actual repeated transmission of the uplink channel in the non-SBFD symbol.

[0296] Taking the uplink channel as the PUSCH, in some embodiments, at least one of the following may be included: performing actual repeated transmission corresponding to the repetition type A in the SBFD symbol; performing actual repeated transmission of the repetition type B in the SBFD symbol.

[0297] In some embodiments, at least one of the following may be included: performing actual repeated transmission of the repetition type A in the non-SBFD symbol; performing actual repeated transmission of the repetition type B in the non-SBFD symbol.

[0298] In the embodiments of the present application, the nominal repeated transmission of the uplink channel includes actual repeated transmission in the SBFD symbol and / or actual repeated transmission in the non-SBFD symbol, that is, the nominal repeated transmission is segmented according to the type of the transmitted symbol, so that different types of symbols can be transmitted on different resources, ensuring that different types of symbols can be transmitted, ensuring the reliability and success rate of data transmission, and further improving the utilization rate and transmission efficiency of network resources.

[0299] As mentioned above, in case of time domain span of the uplink channel transmission over SBFD symbols and non-SBFD symbols, the nominal repeated transmission segments into multiple actual repeated transmissions. As mentioned above, the nominal repeated transmission of the uplink channel can include actual repeated transmissions at SBFD symbols; and / or, actual repeated transmissions at non-SBFD symbols.

[0300] As mentioned above, the frequency hopping information includes the RB offset, which can be the first offset and / or the second offset. That is, the frequency hopping information includes the first offset associated with SBFD symbols and / or the second offset associated with non-SBFD symbols.

[0301] Optionally, the transmission power adopted by the uplink channel in the repeated transmission, i.e., the second power, includes at least one of:

[0302] The first transmission power, which is the power of the first type of repeated transmission, is calculated by a first power control parameter corresponding to the SBFD symbol, the first power control parameter including at least one of: a first initial power, a path loss information of the uplink channel, or a first symbol quantity, which is the number of symbols corresponding to the actual repeated transmission or the number of symbols of one nominal repeated transmission, and the first initial power is the initial power in case that the transmission occasion i is at the SBFD symbol.

[0303] The second transmission power, which is the power of the second type of repeated transmission, is calculated by a second power control parameter corresponding to the non-SBFD symbol, the second power control parameter including at least one of: a second initial power, a path loss information of the uplink channel, or a second symbol quantity, which is the number of symbols corresponding to the actual repeated transmission or the number of symbols of one nominal repeated transmission, and the second initial power is the initial power in case that the transmission occasion i is at the non-SBFD symbol.

[0304] Optionally, the parameter i is an index of the uplink channel at the i-th transmission occasion / transmission time.

[0305] In some embodiments, it can include performing the nominal repeated transmission of the uplink channel at the SBFD symbol according to the first transmission power, and the sending power of the nominal repeated transmission is the first transmission power.

[0306] In some embodiments, it can include performing the nominal repeated transmission of the uplink channel at the non-SBFD symbol according to the second transmission power, and the sending power of the nominal repeated transmission is the second transmission power.

[0307] In some embodiments, the first type of repeated transmission can be performed according to a first transmission power, and the second type of repeated transmission can be performed according to a second transmission power. That is, the actual repeated transmission in the SBFD symbol is transmitted at the first transmission power, and the actual repeated transmission in the non-SBFD symbol is transmitted at the second transmission power.

[0308] It should be understood that the first transmission power or the second transmission power can satisfy the following formula one:

[0309] The meanings and values of the various power control parameters in the formula can be referred to the description above, and will not be repeated here.

[0310] In the embodiment, the first transmission power refers to the power of the first type of repeated transmission, which can be calculated by inputting the first power control parameter corresponding to the SBFD symbol into formula one. The first transmission power can refer to the power calculated by inputting the first power control parameter into formula one.

[0311] As known from the above, the difference from the related art is that the calculation parameter of the first transmission power is improved in the embodiment, and the improved parameter can be referred to as the first power control parameter.

[0312] The first power control parameter can include at least one of the following:

[0313] The first initial power refers to the initial power when the transmission occasion i is in the SBFD symbol, and can specifically refer to P O_PUSCH,b,f,c (j) in formula one. That is, for the first transmission power, the first initial power can be used as the value of P O_PUSCH,b,f,c (j) to calculate formula one.

[0314] The first symbol quantity refers to the number of symbols corresponding to the actual repeated transmission or the number of symbols of one nominal repeated transmission. The first symbol quantity can specifically refer to in formula one. That is, for the first transmission power, the first symbol quantity can be used as the value of in formula one to calculate.

[0315] The path loss information of the uplink channel can include a path loss compensation parameter (higher layer filtered RSRP) and a path loss reference signal power parameter (referenceSignalPower). As recorded above, the power control parameter 3: PL b,f,c (q d ). That is, for the first transmission power, the path loss information of the uplink channel can be used as PL b,f,c (qd ) into formula one.

[0316] Optionally, the first initial power, the first number of symbols, and / or the path loss information of the uplink channel can be obtained by the network device configuring the terminal. For example, the network device can use a certain signaling to carry the first initial power, the first number of symbols, and / or the path loss information of the uplink channel. The signaling may, for example, be any type of signaling such as MAC CE signaling, DCI signaling, or custom signaling.

[0317] In this embodiment, the second transmission power refers to the power of the second type of repeated transmission, which can be calculated by using the second power control parameter corresponding to the non-SBFD symbol to obtain the second transmission power. The second transmission power can refer to the power obtained by inputting the second power control parameter into formula one.

[0318] As known from the above, the difference from the related art is that the calculation parameter of the second transmission power is improved in this embodiment, and the improved parameter can be referred to as the second power control parameter.

[0319] The second power control parameter can include at least one of the following:

[0320] The second initial power refers to the initial power in the case where the transmission occasion i is a non-SBFD symbol, and specifically can refer to P O_PUSCH,b,f,c (j) in formula one. That is, for the second transmission power, the second initial power can be used as the value of P O_PUSCH,b,f,c (j) to be substituted into formula one for calculation.

[0321] The second number of symbols refers to the number of symbols corresponding to the actual repeated transmission or the number of symbols of one nominal repeated transmission. The second number of symbols can specifically refer to The value of this parameter is the second number of symbols. That is, for the second transmission power, the second number of symbols can be used as the value of to be substituted into formula one for calculation.

[0322] The path loss information of the uplink channel can include a path loss compensation parameter (higher layer filtered RSRP) and a path loss reference signal power parameter (referenceSignalPower). As recorded above, the power control parameter 3: PL b,f,c (q d ). That is, for the second transmission power, the path loss information of the uplink channel can be used as the value of PL b,f,c (q d ) to be substituted into formula one for calculation.

[0323] Optionally, the path loss information of the uplink channel can also refer to a power variation amount of a transmission power and a reception power of the uplink channel. The transmission power can be, for example, an average transmission power of the uplink channel, and the reception power can be, for example, an average reception power of the uplink channel.

[0324] Optionally, the second initial power, the second symbol quantity, and / or the path loss information of the uplink channel can be obtained by the network device for configuration of the terminal. For example, the network device can use a certain signaling to carry the second initial power, the second symbol quantity, and / or the path loss information of the uplink channel. The signaling can be, for example, any type of signaling such as MAC CE signaling, DCI signaling, or custom signaling.

[0325] It should be noted that the first power control parameters corresponding to different first type of repeated transmissions can be the same. The first power control parameters corresponding to different first type of repeated transmissions can also be different.

[0326] For example, if the first type of repeated transmission includes actual repetition #1 and actual repetition #2.

[0327] Then the first transmission power 1 corresponding to the actual repetition #1 can be determined according to the first power control parameter 1 corresponding to the actual repetition #1, wherein the parameters in the first power control parameter 1 are parameters corresponding to the actual repetition #1, for example, the first symbol quantity in the first power control parameter 1 refers to the symbol quantity corresponding to the actual repetition #1.

[0328] The first transmission power 2 corresponding to the actual repetition #2 can be determined according to the first power control parameter 2 corresponding to the actual repetition #2, wherein the parameters in the first power control parameter 2 are parameters corresponding to the actual repetition #2, for example, the first symbol quantity in the first power control parameter 2 refers to the symbol quantity corresponding to the actual repetition #2. The same applies to the second type of repeated transmission, which will not be described here.

[0329] In the embodiments of the present application, the corresponding second power is determined for different types of symbols, which can make the calculation of the second power consider the characteristics of the nominal repeated transmission segmented according to different symbols, reflect the individualized power calculation of the different actual repeated transmissions or nominal repeated transmissions in the communication system, and further ensure more effective data transmission of the terminal according to the second power when performing communication transmission of the uplink channel, which can further improve the utilization of network resources and transmission efficiency.

[0330] As described above, the power control parameter 5 uses the first symbol quantity and / or the second symbol quantity, and the values of the first symbol quantity and the second symbol quantity can be different based on whether the nominal repeated transmission is segmented and transmitted. The following briefly describes several possible implementation modes of the second power:

[0331] Embodiment 1, the second power includes at least one of: the first transmission power or the second transmission power.

[0332] The first transmission power includes: a repetition power of the SBFD part, the repetition power of the SBFD part is calculated using a first symbol quantity, the first symbol quantity refers to a symbol quantity of a nominal repeated transmission.

[0333] The second transmission power includes: a repetition power of the non-SBFD part, the repetition power of the non-SBFD part is calculated using a second symbol quantity, the second symbol quantity can refer to a symbol quantity of a nominal repeated transmission.

[0334] Embodiment 2, the second power includes at least one of: the first transmission power or the second transmission power.

[0335] The first transmission power includes: a repetition power of the SBFD part, the repetition power of the SBFD part is calculated using a first symbol quantity, the first symbol quantity refers to a symbol quantity corresponding to an actual repeated transmission.

[0336] The second transmission power includes: a repetition power of the non-SBFD part, the repetition power of the non-SBFD part is calculated using a second symbol quantity, the second symbol quantity can refer to a symbol quantity corresponding to an actual repeated transmission.

[0337] As described above, formula two is used to determine the reference transmit power, and in this embodiment, the reference transmit power of different symbol types is different. For example, the first initial power can include a first reference transmit power corresponding to the SBFD symbol type. The second initial power can include a second reference transmit power corresponding to the non-SBFD symbol type.

[0338] The first reference transmit power uses P O_UE_PUSCH,b,f,c (j) represents. The second reference transmit power uses P O_UE_PUSCH,b,f,c (j)' represents.

[0339] The P O_UE_PUSCH,b,f,c (j) value of the actual repeated transmission of the SBFD symbol, and / or, the P O_UE_PUSCH,b,f,c (j)' value of the actual repeated transmission of the non-SBFD symbol will be described in detail.

[0340] The first value of the configuration set index j also includes:

[0341] The P O_UE_PUSCH,b,f,c (j) value of the actual repeated transmission of the SBFD symbol is configured based on a first parameter (such as P0-PUSCH-Alpha2); and / or, the P O_UE_PUSCH,b,f,c(j) the value of is configured based on a second parameter (e.g., P0-PUSCH-Alpha).

[0342] wherein the first number can be 1. For transmission or repeated transmission of uplink channel configured by ConfiguredGrantConfig, j = 1. The repeated transmission can be, for example, a semi-static scheduling transmission.

[0343] In some embodiments, when j = 1, the values of the reference transmission power under different symbol types are configured using the following method:

[0344] If the higher layer signaling or MAC-CE signaling or DCI signaling configures only transmission in SBFD symbols, the P O_UE_PUSCH,b,f,c (1) the value of is configured by a first parameter (e.g., P0-PUSCH-Alpha2); or, the higher layer signaling or MAC-CE signaling or DCI signaling configures only transmission in non-SBFD symbols, the P O_UE_PUSCH,b,f,c (1) the value of is configured by a second parameter (e.g., P0-PUSCH-Alpha).

[0345] If the higher layer signaling or MAC-CE signaling or DCI signaling configures transmission across SBFD symbols and non-SBFD symbols, the P O_UE_PUSCH,b,f,c (1) the value of is configured by a first parameter (e.g., P0-PUSCH-Alpha2); and the P O_UE_PUSCH,b,f,c (1) the value of is configured by a second parameter (e.g., P0-PUSCH-Alpha).

[0346] Method two, in the case where the configuration set index is a second number and the first information is configured.

[0347] wherein the second number can be greater than or equal to 2, and based on the value of the second number, there are two cases:

[0348] Case 1, if the second number takes a value of 2 and the first information is configured, further comprising:

[0349] In response to the first information being a first identifier, the P O_UE_PUSCH,b,f,c (j) takes the first power configuration pair P0-PUSCH-AlphaSet in the first configuration pair set (e.g., P0-AlphaSets); and the P O_UE_PUSCH,b,f,c(j) Take the first power configuration pair P0-PUSCH-AlphaSet in the second configuration pair set (named P0-AlphaSets2). The power configuration pair includes a reference parameter (such as P0) and a loss parameter (such as Alpha).

[0350] The first identifier may be, for example, "0" or "00".

[0351] Alternatively, in response to the first information being a second identifier, the P O_UE_PUSCH,b,f,c (j)' Take the second value in the first configuration pair (named P0-PUSCH-Set) with the lowest P0-PUSCH-SetID value; the P O_UE_PUSCH,b,f,c (j) Take the second value in the second configuration pair (named P0-PUSCH-Set2) with the lowest P0-PUSCH-SetID value.

[0352] The second identifier may be, for example, "1" or "01".

[0353] Alternatively, in response to the first information being a third identifier, the P O_UE_PUSCH,b,f,c (j)' Take the second value in the first configuration pair (named P0-PUSCH-Set) with the lowest P0-PUSCH-SetID value; the P O_UE_PUSCH,b,f,c (j) Take the second value in the second configuration pair (named P0-PUSCH-Set2) with the lowest P0-PUSCH-SetID value.

[0354] The third identifier may be, for example, "10".

[0355] In case 2, if the second value is greater than 2 and the first information is configured, the following is further included:

[0356] If the value of the first information is the first identifier, the P O_UE_PUSCH,b,f,c (j)' Take the first P0-PUSCH-AlphaSet in P0-AlphaSets; the P O_UE_PUSCH,b,f,c (j) Take the first P0-PUSCH-AlphaSet in P0-AlphaSets2.

[0357] If the value of the first information is the second identifier, the P O_UE_PUSCH,b,f,c(j)' Takes the first value in P0-PUSCH-Set with the smallest P0-PUSCH-SetID value; after segmentation, the P in the actual repeated transmission of the SBFD symbol is... O_UE_PUSCH,b,f,c (j) Take the first value in P0 PUSCH Set2 that has the smallest P0-PUSCH-SetID value.

[0358] If the value of the first information is the third identifier, then the P segment is in the actual retransmission of non-SBFD symbols after segmentation. O_UE_PUSCH,b,f,c (j)' Takes the second value in P0-PUSCH-Set that has the smallest P0-PUSCH-SetID value; after segmentation, the P in the actual repeated transmission of the SBFD symbol is... O_UE_PUSCH,b,f,c (j) Take the second value in P0-PUSCH-Set2 that has the smallest P0-PUSCH-SetID value.

[0359] Method 3, when the configuration set index is the second value and no first information is configured, also includes:

[0360] If the second value is 2, then the P segment is in the actual repeated transmission of non-SBFD symbols after segmentation. O_UE_PUSCH,b,f,c (j)′ takes the value of P0 in the first P0-PUSCH-AlphaSet of P0-AlphaSets. The P0 in the actual retransmission of non-SBFD symbols after segmentation. O_UE_PUSCH,b,f,c (j) takes the value of P0 in the first P0-PUSCH-AlphaSet in P0-AlphaSets2.

[0361] Alternatively, if the second value is greater than 2, then P O_UE_PUSCH,b,f,c The value of (j) is obtained through the following signaling:

[0362] PUSCH-PowerConfig->P0-PUSCH-AlphaSet

[0363] Where P0-PUSCH-AlphaSet is a set, retrieved using P0-PUSCH-AlphaSetId as the index, and the "SRS resource indicator" field in DCI format 0_1 ​​can specify the following fields:

[0364] PUSCH-PowerConfig->SRI-PUSCH-PowerControl->SRI-PUSCH-PowerControlId

[0365] After that, the field is associated to a specified P0-PUSCH-AlphaSetId, and finally a certain power parameter in the P0-PUSCH-AlphaSet set is found.

[0366] In some embodiments, the first information can be an open-loop power control parameter set indication field.

[0367] In some embodiments, the first information can be an open-loop power control parameter set indication field.

[0368] In some embodiments, the transmission of the uplink channel includes nominal repeated transmissions, and in the case of frequency hopping transmission of the uplink channel based on the frequency hopping information, also includes:

[0369] In response to the actual repeated transmission within the nth nominal repeated transmission performed in the SBFD symbol, the starting RB index of the actual repeated transmission includes a first index, the first index is calculated based on the index of the starting resource block in the uplink bandwidth part and the first offset associated with the SBFD symbol, and n is an integer greater than or equal to 1.

[0370] Alternatively, in response to the actual repeated transmission within the nth nominal repeated transmission performed in the non-SBFD symbol, the starting RB of the actual repeated transmission includes a second index, the second index is calculated based on the index of the starting resource block in the uplink bandwidth part and the second offset associated with the non-SBFD symbol.

[0371] Optionally, the SBFD symbol can refer to a symbol of the SBFD symbol type. The non-SBFD symbol can refer to a symbol of the non-SBFD symbol type.

[0372] The actual repeated transmission within the nth nominal repeated transmission performed in the SBFD symbol can also be referred to as the actual repeated transmission within the nth nominal repeated transmission performed in the SBFD symbol type. The actual repeated transmission within the nth nominal repeated transmission performed in the non-SBFD symbol can also be referred to as the actual repeated transmission within the nth nominal repeated transmission performed in the non-SBFD symbol type.

[0373] It can be understood that the actual repeated transmission of the nth nominal repeated transmission can refer to any one of the multiple actual repeated transmissions included in the nth nominal repeated transmission.

[0374] The first index can refer to the index corresponding to the starting resource block of the actual repeated transmission in the SBFD symbol.

[0375] The first index can be calculated by adding the index of the starting resource block within the uplink bandwidth part and the first offset associated with the SBFD symbol. Specifically, the first index can be obtained by adding the index of the starting resource block within the uplink bandwidth part and the first offset associated with the SBFD symbol.

[0376] Optionally, different actual repeated transmissions in the SBFD symbol can employ the same first offset. Of course, different actual repeated transmissions in the SBFD symbol can also employ different first offsets.

[0377] For example, K first offsets for K actual repeated transmissions can be determined, which are first offset 1, first offset 2, first offset 3, …, and first offset K, respectively. The first offset 1 can be employed for the first actual repeated transmission in the SBFD symbol, the first offset 2 can be employed for the second actual repeated transmission, and so on. Of course, the number of actual repeated transmissions is less than or equal to K, and K is an integer greater than or equal to 2.

[0378] The second index can refer to the index corresponding to the starting resource block of the actual repeated transmission in the non-SBFD symbol.

[0379] The second index can be calculated by adding the index of the starting resource block within the uplink bandwidth part and the second offset associated with the non-SBFD symbol. Specifically, the second index can be obtained by adding the index of the starting resource block within the uplink bandwidth part and the second offset associated with the non-SBFD symbol.

[0380] Optionally, different actual repeated transmissions in the non-SBFD symbol can employ the same second offset. Of course, different actual repeated transmissions in the non-SBFD symbol can also employ different second offsets.

[0381] For example, Q second offsets for Q actual repeated transmissions can be determined, which are second offset 1, second offset 2, second offset 3, …, and second offset Q, respectively. The second offset 1 can be employed for the first actual repeated transmission in the non-SBFD symbol, the second offset 2 can be employed for the second actual repeated transmission, and so on. Of course, the number of actual repeated transmissions is less than or equal to Q, and Q is an integer greater than or equal to 2.

[0382] It should be understood that employing frequency hopping transmission based on the frequency hopping information can include employing inter-repetition frequency hopping transmission based on the frequency hopping information. The inter-repetition frequency hopping transmission can refer to calculating a target RB using the RB offset and the initial RB in the frequency hopping information. The first nominal repeated transmission is performed with the initial RB as the starting position of the frequency domain resource, and the second nominal repeated transmission is performed with the target RB as the starting position of the frequency domain resource. The first nominal repeated transmission and the second nominal repeated transmission can be different nominal repeated transmissions.

[0383] Optionally, in the case that the terminal supports inter-repetition frequency hopping, the nominal repetition transmission can be segmented into actual repetition transmissions when the terminal performs repetition transmission. The starting RB index of the actual repetition transmission can be used to determine the starting frequency domain resource of the actual repetition transmission. The length of the frequency domain resource of the actual repetition transmission can be obtained by network configuration. Therefore, for the nth nominal repetition transmission, there is also the possibility of segmentation. The nth nominal repetition transmission can be segmented into multiple actual repetition transmissions.

[0384] For the actual repetition transmission within the nth nominal repetition transmission, if the actual repetition transmission is an SBFD symbol, the starting RB index of the actual repetition transmission includes the first index, and if the actual repetition transmission is a non-SBFD symbol, the starting RB index of the actual repetition transmission includes the second index.

[0385] According to Formula Seven, one value of the first index or the second index can be represented by the following formula:

[0386] RB start (n)=RB start +RB offset .

[0387] Wherein, RB start (n) is the index of the starting RB of the actual repetition transmission within the nth nominal repetition transmission. RB start is the index of the starting RB of the first actual repetition transmission within the nth nominal repetition transmission. RB offset may refer to the index offset of the actual repetition transmission.

[0388] It should be noted that in the embodiment, different symbol types can be associated with respective index offsets. The first offset can refer to the offset of the RB index of the SBFD symbol type. The second offset can refer to the offset of the RB index of the non-SBFD symbol type.

[0389] For ease of understanding, as shown in another resource distribution example diagram of FIG. 7, assuming that the horizontal axis is the time domain and the vertical axis is the frequency domain, three time slots are set in the time domain, which are the first time slot, the second time slot and the third time slot, and each time slot contains 14 symbols.

[0390] Assuming that the first time slot contains nominal repetition #3, and the second time slot contains nominal repetition #4. The first time slot is an SBFD region, the second time slot belongs to an SBFD region and a non-SBFD region, and the third time slot is a non-SBFD region.

[0391] As shown in FIG. 7, nominal repetition #3 is not segmented, and nominal repetition #4 is segmented into actual repetition #41 and actual repetition #42. The segmentation manner of the nominal repetition transmission can use the segmentation manner disclosed in the present application or can be combined with the existing segmentation manner.

[0392] Actual repetition #41 is an SBFD region, and actual repetition #42 is a non-SBFD region. Therefore, the starting resource block of actual repetition #41 is a first index, which is calculated based on a first offset of the SBFD symbol type. The starting resource block of actual repetition #42 is a second index, which is calculated based on a second offset of the non-SBFD symbol type.

[0393] When the first offset and the second offset are equal, the frequency domain resource starting positions of actual repetition #41 and actual repetition #42 are equal, as shown in actual repetition #41 and actual repetition #42 in FIG. 7, which are on the same frequency domain resource.

[0394] When the first offset and the second offset are not equal, the first index corresponding to the SBFD type and the second index corresponding to the non-SBFD type are different. As shown in actual repetition #41 and actual repetition #42 in FIG. 8, which are on different frequency domain resources.

[0395] In the embodiments of the present application, by configuring different index offsets for different symbol types, the configuration manner of different symbol types in the frequency domain is more flexible, which can effectively solve the frequency domain conflict phenomenon and effectively improve the frequency domain management efficiency and effectiveness.

[0396] As described above, when the nominal repetition transmission is segmented into a plurality of actual repetition transmissions, the nominal repetition transmission can be segmented into a plurality of actual repetition transmissions by using the unavailable symbol. The unavailable symbol will be described in detail below with reference to FIGS. 9a-9g. It should be noted that in FIGS. 9a-9g, U represents an uplink symbol, D represents a downlink symbol, and F represents a flexible symbol.

[0397] In some embodiments, the unavailable symbol can include at least one of the following 1st-10th symbols.

[0398] The 1st symbol: a first downlink symbol, which refers to a downlink symbol that is not configured as an SBFD symbol.

[0399] In an SBFD system, in some possible implementation manners, the first downlink symbol can include a downlink symbol that is not configured as an SBFD symbol or a downlink symbol that is configured as a non-SBFD symbol. The downlink symbol that is not configured as an SBFD symbol or is configured as a non-SBFD symbol can also be referred to as a downlink non-SBFD symbol.

[0400] Optionally, the first downlink symbol can be indicated by the first indication information. That is, the first indication information can be used to indicate the unavailable symbol as the downlink symbol and not configured as the SBFD symbol. The first indication information can be carried in the first signaling, which can be, for example, the TDD uplink-downlink configuration common (tdd UL DL Configuration Common) signaling or the TDD uplink-downlink configuration dedicated (tdd UL DL Configuration Dedicated) signaling.

[0401] For example, the first indication information can include two bits. The first bit is used to indicate the uplink symbol or the downlink symbol, and the second bit is used to indicate the SBFD symbol or the non-SBFD symbol. For example, the first bit is "1" or "0", "1" refers to the downlink symbol, and "0" refers to the uplink symbol. The second bit is "1" or "0", "1" refers to the SBFD symbol, and "0" refers to the non-SBFD symbol. That is, if the first indication information is "10", it means that the downlink symbol configured as the non-SBFD symbol is the unavailable symbol.

[0402] Optionally, the terminal can first determine the symbol of the downlink symbol and configured as the SBFD symbol, and then determine the unavailable symbol as the downlink symbol in all downlink symbols except the symbol configured as the SBFD symbol.

[0403] Optionally, the terminal can also first configure at least one of the downlink symbol, the uplink symbol or the flexible symbol, and then indicate the unavailable symbol in the downlink symbol, the uplink symbol or the flexible symbol. For example, the unavailable symbol can include: the symbol in the downlink symbol not configured as the SBFD symbol, or the symbol in the uplink symbol configured as the non-SBFD symbol, or the symbol in the flexible symbol configured as the non-SBFD symbol.

[0404] FIG. 9a shows an example diagram of an unavailable symbol. Referring to FIG. 9a, the nominal repetition #2 located in the time slots n and n+1 includes the actual repetitions #21 and #22, wherein the downlink symbol corresponding to #22 is the downlink symbol D configured as the non-SBFD symbol, and the downlink symbol corresponding to #22 is determined as the unavailable symbol, that is, the downlink symbol corresponding to #22 belongs to the first downlink symbol. The nominal repetition #3 located in the time slot n+1 includes the actual repetitions #31 and #32, wherein the downlink symbol corresponding to #32 is the downlink symbol D configured as the non-SBFD symbol, and the downlink symbol corresponding to #32 is also determined as the unavailable symbol, that is, the downlink symbol corresponding to #32 also belongs to the first downlink symbol.

[0405] The second type of symbol: the uplink channel is transmitted in the non-SBFD symbol, and the downlink symbol or the flexible symbol configured as the SBFD symbol.

[0406] In some embodiments, the uplink channel, such as PUSCH, can not be transmitted in the SBFD symbol, and only be transmitted in the non-SBFD symbol. In this case, the first indication information can indicate the unavailable symbol as the downlink symbol or the flexible symbol configured as the SBFD symbol.

[0407] For example, the first indication information can include four bits. The first two bits indicate the symbol type, the third bit indicates the SBFD symbol or the non-SBFD symbol, and the fourth bit indicates the symbol transmission type. For example, the first two bits are "01" indicating the downlink symbol, "10" indicating the flexible symbol, and "11" indicating the downlink symbol or the flexible symbol. The third bit is "1" or "0", "1" indicating the SBFD symbol, and "0" indicating the non-SBFD symbol. The fourth bit is "1" or "0", "1" indicating the uplink channel transmission in the SBFD symbol, and "0" indicating the uplink channel transmission in the non-SBFD symbol. That is, the first indication information is "1110", which means that the unavailable symbol is the downlink symbol or the flexible symbol configured as the SBFD symbol when the uplink channel is transmitted in the non-SBFD symbol.

[0408] Optionally, the uplink channel transmission in the non-SBFD symbol can refer to the nominal repeated transmission of the uplink channel in the non-SBFD symbol.

[0409] In some embodiments, the downlink symbol configured as the SBFD symbol can also be referred to as the downlink SBFD symbol. The flexible symbol configured as the SBFD symbol can also be referred to as the flexible SBFD symbol. The flexible symbol configured as the non-SBFD symbol or the flexible symbol not configured as the SBFD symbol can also be referred to as the flexible non-SBFD symbol.

[0410] FIG. 9b shows another example of the unavailable symbol. Referring to FIG. 9b, if the PUSCH can only be transmitted in the non-SBFD symbol, the nominal repetition #2 located in the slots n and n+1 is segmented into actual repetitions #21 and #22. The symbols 1 and 2 corresponding to #22 are both downlink symbols D configured as the SBFD symbol, so the symbols 1 and 2 corresponding to #22 are both unavailable symbols. The symbols 3-4 corresponding to the nominal repetition #3 are downlink symbols D configured as the SBFD symbol, and the symbols 5-7 are flexible symbols F configured as the SBFD symbol. Since the uplink channel can only be transmitted in the non-SBFD symbol, the symbols 3-7 of the nominal repetition #3 are all unavailable symbols.

[0411] In addition, the symbol 8 of the nominal repetition #3 is an uplink symbol U configured as the non-SBFD symbol, and the symbol 8 does not belong to the second type of symbol. However, since the symbol 8 is a single symbol, the symbol is also unavailable. The symbols 9-10 corresponding to the nominal repetition #4 are uplink symbols U configured as the non-SBFD symbol, so the symbols 9-10 are all available symbols.

[0412] The third type of symbol: an uplink symbol or a flexible symbol configured as a non-SBFD symbol in the SBFD symbol transmission.

[0413] In some embodiments, the uplink channel, such as the PUSCH, can not be transmitted in the non-SBFD symbol, and can only be transmitted in the SBFD symbol. In this case, the first indication information can indicate the uplink symbol or the flexible symbol configured as the non-SBFD symbol.

[0414] For example, the uplink channel transmission in the SBFD symbol can refer to the nominal repeated transmission of the uplink channel in the SBFD symbol.

[0415] In some embodiments, the first indication information can be used to indicate that the unavailable symbol is the uplink symbol or the flexible symbol configured as the non-SBFD symbol in the SBFD symbol transmission.

[0416] As described above, the first indication information includes four bits, and the meanings of the four bits are as described above. In this case, if the first indication information is “1101”, it means that the unavailable symbol is the uplink symbol or the flexible symbol configured as the non-SBFD symbol in the SBFD symbol transmission.

[0417] In some embodiments, the uplink symbol configured as the non-SBFD symbol can be referred to as the uplink non-SBFD symbol, and the flexible symbol configured as the non-SBFD symbol can be referred to as the flexible non-SBFD symbol.

[0418] FIG. 9c shows another example of unavailable symbols. Referring to FIG. 9c, if the PUSCH can only be transmitted in the SBFD symbol, the symbols 5-10 corresponding to the nominal repetition #1 are the uplink symbol U and the flexible symbol F configured as the non-SBFD symbol, and the symbols 5-10 are all unavailable symbols. The symbols 11-14 corresponding to the nominal repetition #2 are the uplink symbol U configured as the non-SBFD symbol, and the symbols 11-14 corresponding to the nominal repetition #2 are all unavailable symbols. The symbols 9-14 corresponding to the nominal repetition #4 are all uplink symbols configured as the non-SBFD symbol, and the symbols 9-14 corresponding to the nominal repetition #4 are all unavailable symbols.

[0419] The fourth type of symbol: a non-SBFD symbol in a control resource set (CORESET), which is a resource set of control information associated with a type 0 physical downlink control channel (PDCCH) common search space (CSS) set, i.e., the CORESET is a type 0 PDCCH CSS set.

[0420] Optionally, the CORESET can be indicated by the second indication information.

[0421] In some embodiments, the second indication information can be carried in a System Information Block 1 (SIB1) message in master information block (MIB) signaling. The SIB1 message may, for example, be a pdcch-ConfigSIB1 message in MIB signaling.

[0422] In some embodiments, the second indication information can be carried in a System Information Block 1 (SIB1) message in master information block (MIB) signaling. The SIB1 message may, for example, be a pdcch-ConfigSIB1 message in MIB signaling.

[0423] Optionally, the non-SBFD symbol in the CORESET can be indicated by third indication information.

[0424] It can be understood that the network device also transmits the third indication information, and correspondingly, the terminal also receives the third indication information, and the third indication information is used to indicate the non-SBFD symbol in the CORESET.

[0425] Optionally, the non-SBFD symbol in the CORESET refers to a downlink symbol or a flexible symbol configured as a non-SBFD symbol in the CORESET.

[0426] Optionally, when the unavailable symbol includes the non-SBFD symbol in the CORESET, the non-SBFD symbol in the CORESET can be a downlink symbol or a flexible symbol.

[0427] Optionally, the third indication information can indicate that the unavailable symbol is the non-SBFD symbol in the CORESET. The third indication information may, for example, be tdd UL DL ConfigurationCommon signaling.

[0428] For example, the third indication information can include two bits, the first bit indicates whether the unavailable symbol is a symbol in the CORESET, and the second bit indicates whether the unavailable symbol is an SBFD symbol. For example, the first bit is “1” or “0”, “1” indicates that the unavailable symbol is a symbol in the CORESET, and “0” indicates that the unavailable symbol is not a symbol in the CORESET. The second bit is “1” or “0”, “1” indicates an SBFD symbol, and “0” indicates a non-SBFD symbol. That is, if the first indication information is “10”, it represents that the non-SBFD symbol in the CORESET is the unavailable symbol.

[0429] Figure 9d shows another example of unavailable symbols, referring to Figure 9d, symbols 1-2 in slot n+1 corresponding to actual repetition #22 in nominal repetition #2 are both type0 PDCCH CSS, i.e. the symbols 1-2 are downlink symbols D configured as non-SBFD symbols in CORESET. Therefore, symbols 1-2 are both unavailable symbols.

[0430] Category 5 symbols: SBFD symbols in CORESET when uplink channels are transmitted in SBFD symbols.

[0431] Optionally, the SBFD symbols in CORESET can be indicated by: indicating the CORESET by the second indication information, and then indicating the symbols configured as SBFD symbols in the CORESET.

[0432] Optionally, the third indication information can indicate that the unavailable symbols are SBFD symbols in CORESET when uplink channels are transmitted in SBFD symbols.

[0433] For example, the third indication information can include three bits, the first bit indicates whether the unavailable symbols are symbols in CORESET, the second bit indicates whether the unavailable symbols are SBFD symbols. The third bit indicates whether it is SBFD symbol transmission.

[0434] For example, the first bit is "1" or "0", "1" means that the unavailable symbols are symbols in CORESET, and "0" means that the unavailable symbols are not symbols in CORESET. The second bit is "1" or "0", "1" means SBFD symbol, and "0" means non-SBFD symbol. The third bit is "1" or "0", "1" means that the uplink channel is transmitted in SBFD symbols, and "0" means that the uplink channel is transmitted in non-SBFD symbols.

[0435] That is, the third indication information is "111", which means that the unavailable symbols are SBFD symbols in CORESET when the uplink channel is transmitted in SBFD symbols.

[0436] Further, when the unavailable symbols include SBFD symbols in CORESET, the SBFD symbols refer to uplink symbols or flexible symbols.

[0437] Category 6 symbols: SBFD symbols in CORESET when uplink channels are transmitted across SBFD symbols and non-SBFD symbols.

[0438] In some embodiments, the third indication information can indicate that the unavailable symbols are SBFD symbols in CORESET when the uplink channel is transmitted across SBFD symbols and non-SBFD symbols.

[0439] For example, the third indication information can include four bits, the first bit indicates whether the unavailable symbol is a symbol in the CORESET, the second bit indicates whether the unavailable symbol is an SBFD symbol. The last two bits indicate whether it is SBFD symbol transmission or non-SBFD symbol transmission or cross SBFD symbol and non-SBFD symbol transmission.

[0440] For example, the first bit is "1" or "0", "1" means that the unavailable symbol is a symbol in the CORESET, and "0" means that the unavailable symbol is not a symbol in the CORESET. The second bit is "1" or "0", "1" means SBFD symbol, and "0" means non-SBFD symbol. The third bit is "11" or "10" or "01", "01" means that the uplink channel is transmitted in the SBFD symbol, "10" means that the uplink channel is transmitted in the non-SBFD symbol, and "11" means that the uplink channel is transmitted in the cross SBFD symbol and non-SBFD symbol.

[0441] That is, the third indication information is "1111", which means that the unavailable symbol is the SBFD symbol in the CORESET when the uplink channel is transmitted in the cross SBFD symbol and non-SBFD symbol.

[0442] Further, when the unavailable symbol includes the SBFD symbol in the CORESET, the SBFD symbol refers to the uplink symbol or the flexible symbol.

[0443] For ease of understanding, FIG. 9e shows another example diagram of unavailable symbols, as shown in FIG. 9e, the nominal repetition #1 is transmitted in the cross SBFD symbol and non-SBFD symbol, and the SBFD symbol in the CORESET in the nominal repetition #1 is the unavailable symbol.

[0444] In FIG. 9e, the symbol 8 in the slot n is Type0-PDCCH CSS, that is, the symbol configured as the SBFD symbol in the CORESET, so the symbol 8 is the unavailable symbol.

[0445] If the PUSCH cannot be transmitted in the non-SBFD symbol and can only be transmitted in the SBFD symbol, or if the PUSCH can be transmitted in the cross SBFD symbol and non-SBFD symbol, the SBFD symbol in the CORESET is the unavailable symbol.

[0446] The seventh type of symbol: invalid symbol, the invalid symbol refers to one or more symbols after the last symbol of the continuous non-SBFD symbol.

[0447] Optionally, the invalid symbols can be one or more symbols after a last symbol of consecutive non-SBFD symbols in the downlink. The consecutive non-SBFD symbols can be referred to as consecutive sets, and one or more symbols after a last symbol of each consecutive set can be invalid symbols.

[0448] In some embodiments, the invalid symbols can be indicated by high layer signaling. A parameter (named numberOfInvalidSymbolsForDL UL Switching) of invalid symbols of uplink / downlink is configured in the high layer signaling. In a case where the parameter is configured, one or more symbols after a last symbol of consecutive non-SBFD symbols in the downlink can be invalid symbols.

[0449] The parameter of invalid symbols of uplink / downlink can indicate a symbol quantity of invalid symbols of uplink / downlink. For example, the high layer signaling can configure the symbol quantity of invalid symbols of uplink / downlink as 2, and the symbol quantity of invalid symbols of uplink / downlink is 2.

[0450] The downlink can include a plurality of symbols, and the plurality of symbols can include one or more non-SBFD symbols and / or SBFD symbols. The consecutive non-SBFD symbols refer to a plurality of non-SBFD symbols that are adjacent in position in the plurality of symbols of the downlink.

[0451] Further, assuming that the symbol quantity of invalid symbols of uplink / downlink is P, P is an integer greater than or equal to 0, then P symbols after a last symbol of each consecutive set of all non-SBFD symbols are invalid symbols, that is, unusable symbols. For example, when P is 2, then 2 symbols after a last symbol of each consecutive set of all non-SBFD symbols are invalid symbols.

[0452] In some embodiments, the first indication information can also be used to indicate the symbol quantity of invalid symbols. For example, the first indication information can take a value of “2”, and the symbol quantity of invalid symbols is 2, so the invalid symbols are 2 symbols after a last symbol of consecutive non-SBFD symbols.

[0453] In yet some embodiments, in a case where the invalid symbols of uplink / downlink are configured, the symbol quantity P of invalid symbols is determined based on a SCS configuration reference subcarrier spacing.

[0454] The symbol quantity P of invalid symbols is preset, and a time length of each symbol is related to the subcarrier spacing.

[0455] Further, the first indication information is also used to indicate the SCS configuration reference subcarrier spacing, so that the terminal determines the symbol quantity P of invalid symbols according to the SCS configuration reference subcarrier spacing.

[0456] FIG. 9f shows another example of unavailable symbols. Referring to FIG. 9f, symbols 1-2 of slot n+1 are downlink symbols configured as non-SBFD symbols, that is, the consecutive set of all non-SBFD symbols in slot n+1 is symbols 1-2, the last symbol of the consecutive set is symbol 2, and the two symbols after symbol 2 are invalid symbols, that is, flexible symbols 3-4 are both configured as unavailable symbols. Therefore, symbols 1-4 are all unavailable symbols.

[0457] Category 8 symbols: one or more consecutive symbols after the SBFD symbol boundary.

[0458] Optionally, the high-layer signaling or other signaling can indicate that one or more consecutive symbols after the SBFD symbol boundary are unavailable symbols. In addition, the first indication information can also indicate the SCS configuration reference subcarrier spacing.

[0459] wherein the number of symbols of the one or more consecutive symbols after the SBFD symbol boundary is preset, and the duration of each symbol is related to the subcarrier spacing.

[0460] Further, in the embodiment, the SBFD symbol can refer to a downlink symbol or a flexible symbol configured as an SBFD symbol. The downlink symbol or the flexible symbol configured as the SBFD symbol can be indicated by the first indication information.

[0461] In some embodiments, the number of symbols N of the one or more consecutive symbols after the SBFD symbol boundary is an integer greater than or equal to 0.

[0462] FIG. 9g shows another example of unavailable symbols. The indication information configures N symbols after the SBFD symbol boundary as unavailable symbols, and N is 2. As shown in FIG. 9g, the SBFD symbol boundary is symbol 7 in slot n+1, and in the case where N is 2, the two symbols after symbol 7, that is, symbol 8 and symbol 9, are both unavailable symbols.

[0463] The SBFD symbol boundary can refer to the last symbol in the actual repeated transmission of the SBFD symbol. The one or more consecutive symbols after the SBFD symbol boundary can refer to one or more consecutive non-SBFD symbols after the last symbol in the actual repeated transmission of the SBFD symbol.

[0464] Category 9 symbols: one or more consecutive symbols after the non-SBFD symbol boundary.

[0465] Optionally, the high-layer signaling or other signaling can indicate that one or more consecutive symbols after the non-SBFD symbol boundary are unavailable symbols. In addition, the first indication information can also indicate the SCS configuration reference subcarrier spacing.

[0466] In some embodiments, the number N of the one or more consecutive symbols after the non-SBFD symbol boundary is an integer greater than or equal to 0. Wherein the number N of the one or more consecutive symbols after the non-SBFD symbol boundary is preset, and the time length of each symbol is related to the subcarrier spacing.

[0467] Optionally, the non-SBFD symbol boundary can refer to the last symbol in the actual repeated transmission of the non-SBFD symbol. The one or more consecutive symbols after the non-SBFD symbol boundary refer to one or more consecutive SBFD symbols after the last symbol in the actual repeated transmission of the non-SBFD symbol.

[0468] The non-SBFD symbol boundary after M symbols is configured as unavailable symbols by high-layer signaling or other signaling, and M is 2. As shown in FIG. 9g, the non-SBFD symbol boundary is symbol 14 in slot n, and therefore, the two symbols after symbol 14, i.e., symbol 1 and symbol 2 in slot n+1, are unavailable symbols.

[0470] Optionally, all SBFD symbols can be indicated by the fifth indication information first, and then the unavailable symbol pattern (Pattern) of the SBFD symbol can be indicated by the high-layer parameter.

[0471] The high-layer parameter can refer to the invalidSymbolPattern parameter, for example. The high-layer parameter can provide a symbol-level bitmap across one or two slots.

[0472] Unlike using only the high-layer parameter, the third parameter is also used in the present embodiment to indicate the unavailable symbol pattern in the SBFD symbol. The unavailable symbol in the SBFD symbol is indicated by the unavailable symbol pattern.

[0473] The unavailable symbol pattern can refer to the pattern formed by the positions or coordinates of the unavailable symbols drawn with the SBFD symbol as the drawing object.

[0474] In the embodiments of the present application, the unavailable symbol can be at least one of the first to tenth types of symbols, and the unavailable symbol can be adjusted more flexibly by setting multiple unavailable symbols to meet the segmentation requirements in different scenarios and improve the reliability of the communication system.

[0475] In some embodiments, the transmission of the uplink channel comprises a nominal repeated transmission. The transmission configuration information of the uplink channel can further comprise: a first SRS resource set and a second SRS resource set.

[0476] As described above, currently, two SRS resource sets are generally directly associated with K consecutive slots of the uplink channel, and how to associate the two SRS resource sets in the SBFD system is not indicated.

[0477] Therefore, the communication method provided in the embodiments of the present application illustrates this.

[0478] In some embodiments, the association manner of the nominal repeated transmission and the SRS resource set comprises at least one of the following:

[0479] For the nominal repeated transmission in the SBFD symbol or the non-SBFD symbol, the first SRS resource set or the second SRS resource set is applied to the nominal repeated transmission.

[0480] For the nominal repeated transmission in the SBFD symbol and the non-SBFD symbol, the first SRS resource set is applied to the actual repeated transmission in the SBFD symbol, the second SRS resource set is applied to the actual repeated transmission in the non-SBFD symbol, or the second SRS resource set is applied to the actual repeated transmission in the SBFD symbol, and the first SRS resource set is applied to the actual repeated transmission in the non-SBFD symbol.

[0481] As described above, when the nominal repeated transmission of the uplink channel is performed in the SBFD symbol and the non-SBFD symbol, the nominal repeated transmission is segmented into multiple actual repeated transmissions. Therefore, in the nominal repeated transmission, the first SRS resource set is applied to the actual repeated transmission in the SBFD symbol, the second SRS resource set is applied to the actual repeated transmission in the non-SBFD symbol, or the second SRS resource set is applied to the actual repeated transmission in the SBFD symbol, and the first SRS resource set is applied to the actual repeated transmission in the non-SBFD symbol.

[0482] It can be understood that when the terminal uses the configured first and second SRS resource sets, the following methods can be adopted:

[0483] Method 1: using the first or second SRS resource set for the nominal repeated transmission in the SBFD symbol. Specifically, the antenna and the beam can be selected for the nominal repeated transmission according to the first or second SRS resource set, and the nominal repeated transmission in the SBFD symbol is performed through the antenna and the beam.

[0484] Manner 2, using the first or second SRS resource set on the nominal repeated transmission of the non-SBFD symbol. Specifically, the first or second SRS resource set can be used to select an antenna and a beam for the nominal repeated transmission, and the nominal repeated transmission is performed through the selected antenna and beam.

[0485] Manner 3, on the nominal repeated transmission of the SBFD symbol and the non-SBFD symbol, for the multiple actual repeated transmissions of the nominal repeated transmission, using the first SRS resource set on the actual repeated transmission of the SBFD symbol, using the second SRS resource set on the actual repeated transmission of the non-SBFD symbol, or using the second SRS resource set on the actual repeated transmission of the SBFD symbol, using the first SRS resource set on the actual repeated transmission of the non-SBFD symbol.

[0486] Optionally, the first or second SRS resource set can be used to select an antenna and a beam on the nominal repeated transmission to which it is applied, and then the actual repeated transmission is transmitted using the selected antenna and beam on the nominal repeated transmission. The specific content can be referred to the description above, which will not be repeated here.

[0487] In this embodiment, through the association relationship between the two configured SRS resource sets and the nominal repeated transmission, the use of the two SRS resource sets in the SBFD system can be more explicit, and the phenomenon of communication quality decline caused by the ambiguity of the SRS resource set associated with the nominal repeated transmission can be avoided, which helps to improve the communication stability and improve the user experience.
