Network elements may be virtual or physical. The core network may include, for example, at least one of the following: Evolved Packet Core (EPC), 5G Core Network (5GCN), and Next Generation Core (NGC).

As those skilled in the art will know, with the evolution of system architecture and the emergence of new business scenarios, the technical solutions proposed in this disclosure are also applicable to similar technical problems.

[0095] The following embodiments of this disclosure can be applied to the communication system 100 shown in FIG1, or to some of the main bodies, but are not limited thereto. The main bodies shown in FIG1 are illustrative. The communication system may include all or some of the main bodies in FIG1, or may include other main bodies outside of FIG1. ​​The number and form of each main body are arbitrary.

[0097] In some embodiments, in order to achieve full-duplex operation, the network device can configure an uplink subband (UL subband) for the terminal on a downlink (DL) time unit or a flexible time unit, and / or, the network device can configure a DL subband for the terminal on an uplink (UL) time unit or a flexible time unit.

[0098] In some embodiments, the terminal may support transmitting the Physical Uplink Shared Channel (PUSCH) and / or the Physical Uplink Control Channel (PUCCH) via frequency hopping (FH) to obtain frequency diversity gain and improve the transmission performance of the uplink channel.

[0099] When a terminal transmits uplink channels in an inter-slot frequency hopping manner, the network device can provide different frequency hopping offset lists (FH offset lists) for different types of time units, such as different types of symbols.

[0100] The frequency hopping offset can be used to indicate the number of frequency domain resources between the starting frequency domain resource locations of two adjacent hops.

[0101] In some embodiments, the length of the bit field used to indicate the FH offset value in the downlink control information (DCI) that schedules the PUSCH can be determined based on the number of FH offsets contained in the FH offset list.

[0102] In some embodiments, the terminal supports inter-slot frequency hopping, that is, it supports frequency hopping transmission of different frequency domain resources of the PUSCH channel in order to obtain frequency domain diversity gain.

[0103] Network devices can configure frequency hopping offsets for terminals through Radio Resource Control (RRC) signaling.

[0104] Specifically, if the number of resource blocks (RBs) included in the uplink bandwidth part (BWP) is less than 50, the network device can support configuring up to two frequency hopping offsets for the terminal. If the number of RBs included in the UL BWP is greater than or equal to 50, the network device can support configuring up to four frequency hopping offsets for the terminal.

[0105] In some embodiments, when frequency hopping is enabled, the network device can indicate the frequency hopping offset through the Frequency Domain Resource Assignment (FDRA) field carried in the DCI.

[0106] In some embodiments, when the terminal transmits PUSCH using the inter-slot FH method, assuming the first hop is located on the UL BWP and the second hop is located within the UL subband, and the frequency domain range and / or the size of the frequency domain resources occupied by the UL BWP and the UL subband are different, the second hop may exceed the frequency domain range occupied by the UL subband.

[0107] When a terminal transmits PUSCH using the inter-slot FH method, assuming the first hop is located within the UL subband and the second hop is located on the UL BWP, and the frequency domain range and / or the size of the frequency domain resources occupied by the UL BWP and the UL subband are different, the second hop may also exceed the frequency domain range occupied by the UL BWP.

[0108] When the terminal transmits PUSCH using the inter-slot FH method, and all hops are located within the UL subband, if the FH offset list corresponding to the active UL BWP is followed, it may also cause a hop to exceed the frequency domain range occupied by the UL subband.

[0109] In some embodiments, the network device can configure corresponding FH offset lists for terminals in different types of time units, so that each hop of frequency hopping transmission is located within the frequency domain occupied by the uplink subband or uplink BWP.

[0110] In some embodiments, considering that PUSCH can be transmitted via frequency hopping on different types of time units through a single DCI scheduling terminal, it is necessary to ensure that the DCI payload size is the same. If the network device provides terminals with different FH offset list lengths for different types of time units, the bit length of the information field used to indicate the FH offset needs to be determined.

[0111] Figure 2A is an interactive schematic diagram of an information transmission method according to an embodiment of the present disclosure. As shown in Figure 2A, the present disclosure relates to an information transmission method, which includes:

[0112] In step S2101, network device 102 determines the number of bits occupied by the first information field.

[0113] In some embodiments, the first information field may be used to indicate the frequency hopping offset.

[0114] In one example, the frequency hopping offset can refer to the number of frequency domain resources used to indicate the starting frequency domain resource locations between two adjacent hops.

[0115] Frequency domain resources can be in units such as RBs or resource block groups (RBGs), and this disclosure does not limit this.

[0116] For example, the frequency hopping offset can be used to indicate the number of RBs that the starting RB of the (N+1)th hop is separated from the starting RB of the Nth hop. Here, N can be a positive integer, such as 1, 2, 3, etc.

[0117] For example, the frequency hopping offset can be used to indicate the number of RBs that the starting RB of the Nth hop is separated from the starting RB of the (N+1)th hop. Here, N can be an integer, such as 1, 2, 3, etc.

[0118] For example, the specific value of the frequency hopping offset can be any integer. When the frequency hopping offset is a positive integer, it can be used to indicate that the starting RB index of the (N+1)th hop is greater than the starting RB index of the Nth hop, and the index difference is equal to the frequency hopping offset.

[0119] For example, if the frequency hopping offset is 2 and the starting RB index of the Nth hop is 1, then the starting RB index of the (N+1)th hop is 3.

[0120] For example, the specific value of the frequency hopping offset can be any integer. When the frequency hopping offset is a positive integer, it can be used to indicate that the starting RB index of the Nth hop is greater than the starting RB index of the (N+1)th hop, and the index difference is equal to the frequency hopping offset.

[0121] For example, the specific value of the frequency hopping offset can be any integer. When the frequency hopping offset is 0, it can be used to indicate that the starting RB index of the (N+1)th hop is equal to the starting RB index of the Nth hop.

[0122] For example, if the frequency hopping offset is 0 and the starting RB index of the Nth hop is 1, then the starting RB index of the (N+1)th hop is 1.

[0123] For example, the specific value of the frequency hopping offset can be any integer. When the frequency hopping offset is a negative integer, it can be used to indicate that the starting RB index of the (N+1)th hop is less than the starting RB index of the Nth hop, and the index difference is equal to the frequency hopping offset.

[0124] For example, if the frequency hopping offset is -2 and the starting RB index of the Nth hop is 4, then the starting RB index of the (N+1)th hop is 2.

[0125] For example, the specific value of the frequency hopping offset can be any integer. When the frequency hopping offset is a negative integer, it can be used to indicate that the starting RB index of the Nth hop is less than the starting RB index of the (N+1)th hop, and the index difference is equal to the frequency hopping offset.

[0126] In some embodiments, the name of the first information field is not limited, and it may be, for example, "frequency hopping offset information field", "frequency hopping parameter information field", etc.

[0127] In some embodiments, network device 102 may determine the number of bits occupied by the first information field in any of the following ways:

[0128] Method 1: Determine the number of bits occupied by the first information field based on the first quantity and the second quantity.

[0129] In one example, the first quantity may be the number of first frequency hopping offsets configured by network device 102 for terminal 101.

[0130] The first frequency hopping offset can correspond to a first type of time unit. The first type of time unit can be an SBFD time unit.

[0131] The first quantity may refer to the number of first frequency hopping offsets included in the list of first frequency hopping offsets corresponding to the SBFD time unit configured by the network device 102 for the terminal 101.

[0132] In one example, the second quantity could be the number of second frequency hopping offsets configured by network device 102 for terminal 101.

[0133] The second frequency hopping offset can correspond to a second type of time unit. The second type of time unit can be a non-SBFD time unit.

[0134] The second quantity may refer to the number of second frequency hopping offsets included in the list of second frequency hopping offsets corresponding to the non-SBFD time unit configured by the network device 102 for the terminal 101.

[0135] In some embodiments, the time unit types involved in this disclosure include, but are not limited to, at least one of a first type of time unit and a second type of time unit.

[0136] In one example, the first type of time unit can be an SBFD time unit. An SBFD time unit can refer to an uplink time unit or flexible time unit configured with a DL subband, and / or a downlink time unit or flexible time unit configured with a UL subband.

[0137] For example, in Figure 2B, the first type of time unit may include slot#(n+1), slot#(n+2), and slot#(n+3).

[0138] Corresponding to the first type of time unit, this disclosure also includes a second type of time unit, which is a non-SBFD time unit. A non-SBFD time unit refers to an uplink time unit, downlink time unit, or flexible time unit that is not configured with any subband.

[0139] The time units in this disclosure can be in the form of symbols, slots, sub-slots, frames, subframes, etc.

[0140] Bao Gong makes no restrictions on this.

[0141] For example, in Figure 2B, the first type of time unit can include slot#n and slot#(n+4).

[0142] In one example, network device 102 can determine a first value d1 based on the first quantity M mentioned above. The first value d1 is the number of bits occupied by the first information field when indicating the first frequency hopping offset.

[0143] In order for the first information field to indicate any of the first frequency hopping offsets, the first value d1 is the minimum number of bits required to indicate the first frequency hopping offset.

[0144] The first value is d1 = log2(M).

[0145] In one example, network device 102 can also determine a second value d2 based on the second quantity N mentioned above. The second value d2 is the number of bits occupied by the first information field when indicating the second frequency hopping offset.

[0146] In order for the first information field to indicate any of the second frequency hopping offsets, the second value d 2可以It is the minimum number of bits required to indicate the second frequency hopping offset.

[0147] The second value is d2 = log2(N).

[0148] In one example, network device 102 determines the number of bits occupied by the first information field based on the minimum of the first value and the second value.

[0149] For example, the number of bits occupied by the first information field is F = minimum(d1, d2) = minimum(log2(M), log2(N)).

[0150] In one example, network device 102 determines the number of bits occupied by the first information field based on the maximum value of the first value and the second value.

[0151] For example, the number of bits occupied by the first information field is F = maximum(d1, d2) = maximum(log2(M), log2(N)).

[0152] For example, if at least one of d1 and d2 is not an integer, the number of bits occupied by the first information field can be determined based on the minimum or maximum value of the rounded-up value after rounding up at least one of d1 and d2.

[0153] For example, the number of bits occupied by the first information field

[0154] For example, the number of bits occupied by the first information field

[0155] For example, if at least one of d1 and d2 is not an integer, the number of bits occupied by the first information field can be determined based on the minimum or maximum value of the rounded-down value after rounding down at least one of d1 and d2.

[0156] For example, the number of bits occupied by the first information field

[0157] For example, the number of bits occupied by the first information field

[0158] Alternatively, one can round up d1 and down d2, and then determine the number of bits occupied by the first information field based on the maximum or minimum value after rounding.

[0159] For example, the number of bits occupied by the first information field

[0160] For example, the number of bits occupied by the first information field

[0161] Alternatively, d1 can be rounded down and d2 can be rounded up. The number of bits occupied by the first information field can then be determined based on the maximum or minimum value after rounding.

[0162] For example, the number of bits occupied by the first information field

[0163] For example, the number of bits occupied by the first information field

[0164] For example, if at least one of d1 and d2 is not an integer, the number of bits occupied by the first information field can be determined by rounding up the minimum or maximum value of d1 and d2.

[0169] For example, the number of bits occupied by the first information field

[0170] Among them, the above It refers to rounding up. It refers to rounding down to the nearest integer.

[0171] The above is merely an illustrative example, and this disclosure does not limit the scheme for determining the number of bits occupied by the first information field based on the first value and the second value.

[0172] Method 2: Determine the number of bits occupied by the first information field based on the first quantity.

[0173] In one example, the first quantity may be the total number of first frequency hopping offsets configured by network device 102 for terminal 101.

[0174] The first frequency hopping offset can correspond to a first type of time unit. The first type of time unit can be an SBFD time unit.

[0175] The first quantity may refer to the total number of first frequency hopping offsets included in the list of first frequency hopping offsets corresponding to the SBFD time unit configured by the network device 102 for the terminal 101.

[0176] In one example, the first type of time unit can be an SBFD time unit. An SBFD time unit can refer to an uplink time unit or flexible time unit configured with a DL subband, and / or a downlink time unit or flexible time unit configured with a UL subband.

[0177] In one example, network device 102 can determine the first value d1 based on the first quantity M mentioned above.

[0178] The first value is d1 = log2(M).

[0179] In one example, network device 102 determines the number of bits occupied by the first information field based on the first value.

[0180] For example, the number of bits occupied by the first information field is F = d1 = log2(M).

[0181] For example, if d1 is not an integer, the number of bits occupied by the first information field can be determined by rounding up or down d1.

[0182] For example, the number of bits occupied by the first information field

[0183] For example, the number of bits occupied by the first information field

[0184] Method 3: Determine the number of bits occupied by the first information field based on the second quantity.

[0185] In one example, the second quantity could be the total number of second frequency hopping offsets configured by network device 102 for terminal 101.

[0186] The second frequency hopping offset can correspond to a second type of time unit. The second type of time unit can be a non-SBFD time unit.

[0187] The second quantity may refer to the total number of second frequency hopping offsets included in the list of second frequency hopping offsets corresponding to the non-SBFD time unit configured by the network device 102 for the terminal 101.

[0188] In one example, the second type of time unit is the non-SBFD time unit. A non-SBFD time unit refers to an uplink time unit, downlink time unit, or flexible time unit that is not configured with any subband.

[0189] In one example, network device 102 can determine the second value d2 based on the second quantity N mentioned above.

[0190] The second value is d2 = log2(N).

[0191] In one example, network device 102 determines the number of bits occupied by the first information field based on the second value.

[0192] For example, the number of bits occupied by the first information field is F = d2 = log2(N).

[0193] For example, if d2 is not an integer, the number of bits occupied by the first information field can be determined by rounding up or down d2.

[0194] For example, the number of bits occupied by the first information field

[0195] For example, the number of bits occupied by the first information field

[0196] Methods 1 to 3 described above can be predefined methods. For example, the number of bits occupied by the first information field may be determined by the protocol based on a first value and / or a second value.

[0197] For example, in order to take into account the frequency hopping offsets corresponding to different types of time units, the number of bits occupied by the first information field can be determined by means of a first quantity and a second quantity through a protocol agreement.

[0198] Furthermore, in order to indicate any frequency hopping offset corresponding to different types of time units, the number of bits occupied by the first information field can be determined based on the maximum value of the first value (the first value is determined according to the first quantity) and the second value (the second value is determined according to the second quantity).

[0199] Furthermore, in order to take into account the frequency hopping offset corresponding to different types of time units and to minimize the number of bits occupied by the first information field, the number of bits occupied by the first information field can be determined based on the minimum value of the first value (the first value is determined according to the first quantity) and the second value (the second value is determined according to the second quantity).

[0200] For example, in order to improve the availability of frequency hopping transmission on SBFD time units, the number of bits occupied by the first information field can be determined by protocol according to a first quantity.

[0201] For example, in order to improve the utilization of frequency domain resources, considering that the available frequency domain resource range on the non-SBFD time unit (i.e., the frequency domain resource range occupied by the uplink BWP) is generally larger than the available frequency domain resource range on the SBFD time unit (i.e., the frequency domain resource range occupied by the uplink subband), the number of bits occupied by the first information domain can be determined by agreement in the protocol based on the second quantity.

[0202] In one example, network device 102 may also dynamically determine the number of bits occupied by the first information field based on other methods, such as its own policy.

[0203] The above is merely an illustrative example, and this disclosure does not limit the scheme by which the network device 102 determines the number of bits occupied by the first information field.

[0204] In step S2102, network device 102 sends DCI to terminal 101.

[0205] In some embodiments, terminal 101 receives DCI sent by access network device 102, but is not limited thereto. Terminal 101 may also receive DCI sent by other entities, such as relay devices or other terminals. In this case, step S2101 can be omitted.

[0206] In some embodiments, terminal 101 obtains the DCI specified by the protocol, in which case step S2101 is omitted.

[0207] In some embodiments, the terminal 101 obtains the DCI from the upper layer(s), in which case step S2101 is omitted.

[0208] In some embodiments, the terminal 101 performs processing to obtain the DCI, in which step S2101 is omitted.

[0209] In some embodiments, the terminal 101 autonomously implements the function indicated by the DCI, or the above function is the default or default, in which case step S2101 is omitted.

[0210] In some embodiments, terminal 101 may acquire DCI while in a connected state.

[0211] In some embodiments, terminal 101 may acquire DCI while performing uplink coverage enhancement.

[0212] In some embodiments, terminal 101 may receive DCI transmitted by network device 102 through a wireless connection with terminal 101.

[0213] In some embodiments, network device 102 may send DCI when it is necessary to schedule terminal 101 to hop frequency to transmit uplink information.

[0214] In some embodiments, network device 102 may send DCI when uplink coverage enhancement is required.

[0215] In some embodiments, network device 102 can send DCI to terminal 101 via a wireless connection with terminal 101. Of course, network device 102 can also send the DCI payload to terminal 101 after carrying it with other signaling, such as RRC signaling.

[0216] In some embodiments, DCI can be used to schedule the terminal 101 to transmit uplink information via frequency hopping.

[0217] In some embodiments, the name of DCI is not limited, and it may be, for example, "control information", "scheduling information", etc.

[0218] In some embodiments, frequency hopping transmission in this disclosure includes, but is not limited to, at least one of the following: frequency hopping transmission across time units; frequency hopping transmission within time units.

[0219] If the time unit is a time slot, then frequency hopping transmission includes at least one of inter-slot frequency hopping transmission and intra-slot frequency hopping transmission.

[0220] For example, frequency hopping transmission across time units can refer to two adjacent hops being on different time units. For instance, in inter-slot FH, the first hop is located on time slot #1 and the second hop is located on time slot #3.

[0221] For example, frequency hopping transmission within a time unit can refer to two adjacent hops being in the same time unit. For instance, in intra-slot FH, the first hop is located on symbol #1 of time slot #1, and the second hop is located on symbol #2 of time slot #1.

[0222] In some embodiments, uplink information may include, but is not limited to, at least one of the following: PUSCH; PUCCH; Sounding Reference Signal (SRS).

[0223] In one example, the above uplink information enables either inter-slot FH or intra-slot FH.

[0224] In one example, a PUSCH includes, but is not limited to, at least one of the following: a type 2 configured grant (CG) PUSCH; a PUSCH scheduled via DCI and with repetition enabled; or multiple PUSCHs scheduled via a single DCI.

[0225] In some embodiments, different time units may correspond to different frequency hopping parameters.

[0226] In one example, the frequency hopping parameters may include, but are not limited to, at least one of the following: frequency hopping offset; frequency domain resources occupied by the frequency hopping transmission.

[0227] For example, the frequency domain resources occupied by frequency hopping transmission may include, but are not limited to, at least one of the following: frequency domain resources occupied on the uplink subband; frequency domain resources occupied on the uplink BWP.

[0228] For example, the frequency domain resources occupied on the uplink subband include RB#1 to RB#5, and / or the frequency domain resources occupied on the uplink BWP include RB#3 to RB#8.

[0229] The above is merely an illustrative example, and this disclosure does not limit the specific content of the frequency hopping parameters.

[0230] In some embodiments, the DCI includes a third information field, which is used to indicate frequency domain resource allocation.

[0231] In one example, the third information field may include the first information field and the second information field.

[0232] For example, the first information field can be used to indicate the frequency hopping offset.

[0233] For example, the second information field can be used to indicate the frequency domain resources occupied when transmitting the uplink information in frequency hopping on at least one type of time unit.

[0234] The name of the third information field is not limited, and it may be, for example, "FDRA field" or "frequency hopping parameter configuration information field".

[0235] The name of the second information field is not limited, and it can be, for example, "frequency domain resource information field" or "frequency domain configuration information field".

[0236] In some embodiments, to reduce the parsing complexity of the DCI, the number of bits occupied by the third information field in the DCI can remain unchanged. That is, the FDRA field can always occupy S bits, where S is a positive integer.

[0237] The third information field may also include only the first information field, in which case the number of bits occupied by the first information field is S.

[0238] The third information field can also include only the second information field, in which case the number of bits occupied by the second information field is S.

[0239] The third information field can include both the first and second information fields. If the number of bits occupied by the first information field is F, then the number of bits occupied by the second information field can be (SF).

[0240] Network device 102 can configure the frequency domain resources occupied by terminal 101 when transmitting the uplink information in at least one type of time unit in the second information domain.

[0241] For example, the second information field can be used to indicate the starting RB index and the number of RBs occupied when transmitting the uplink information in frequency hopping on at least one type of time unit.

[0242] For example, the second information field can be used to indicate the start RB index and the end RB index when the uplink information is transmitted via frequency hopping on at least one type of time unit.

[0243] For example, the second information field can be used to indicate the termination RB index and the number of RBs occupied when the uplink information is transmitted via frequency hopping on at least one type of time unit.

[0244] For example, the second information field can be used to indicate the starting RB index and the number of RBs occupied by a hop in an SBFD time unit, and / or the starting RB index and the number of RBs occupied by a hop in a non-SBFD time unit.

[0245] For example, the second information field can be used to indicate the starting RB index and the ending RB index occupied by a hop in an SBFD time unit, and / or the starting RB index and the number of RBs occupied by a hop in a non-SBFD time unit.

[0246] For example, the second information field can be used to indicate the start RB index and the end RB index occupied by a hop in an SBFD time unit, and / or the start RB index and the end RB index occupied by a hop in a non-SBFD time unit.

[0247] The above is merely an illustrative example, and this disclosure does not limit the specific content indicated by the second information field.

[0248] In some embodiments, the third information field includes the first information field and the second information field. In the third information field, the first information field may occupy the most significant bit (MSB) of F bits, and the remaining bits may be the second information field.

[0249] In some embodiments, the third information field includes the first information field and the second information field. In the third information field, the first information field may occupy the least significant bit (LSB) of the F bits, and the remaining bits may be the second information field.

[0250] In some embodiments, the number of bits occupied by the second information domain is limited. When the network device 102 configures the frequency domain resources for the terminal 101 according to the first granularity (the default frequency domain resource allocation granularity), the number of bits required may be greater than the number of bits occupied by the second information domain. In this case, the network device 102 can redetermine the frequency domain resource allocation granularity.

[0251] In one example, the granularity of frequency domain resource allocation corresponding to the second information domain can be determined based on the first granularity and the third value.

[0252] In one example, the first granularity is the default frequency domain resource allocation granularity.

[0253] In one example, the first granularity could be an initial or default frequency domain resource allocation granularity defined by the protocol.

[0254] In one example, the first granularity could be an initial or default frequency domain resource allocation granularity configured by network device 102 via signaling.

[0255] In one example, the granularity of frequency domain resource allocation can refer to the smallest unit of frequency domain resource allocation. For example, the granularity of frequency domain resource allocation can be n RBs, where n is a positive integer. That is, when configuring frequency domain resources, network device 102 configures them in groups of n RBs.

[0256] Taking network device 102 as an example of configuring frequency domain resources using a bitmap method, each bit in the bitmap corresponds to n RBs. For example, if the bitmap is 11100 and n is 2, then the frequency domain resources configured by network device 102 include RB#0, RB#1, RB#2, RB#3, RB#4, and RB#5.

[0257] In one example, the third value can be greater than or equal to 1.

[0258] For example, if the third value is equal to 1, then the granularity of frequency domain resource allocation corresponding to the second information domain is determined based on the first granularity.

[0259] For example, if the third value is greater than 1, then the granularity of frequency domain resource allocation corresponding to the second information domain is greater than the first granularity.

[0260] For example, the third value can be determined based on the ratio of the first frequency domain resource count to the second frequency domain resource count. The first frequency domain resource count can be the number of frequency domain resources included in the uplink partial bandwidth (BWP), and the second frequency domain resource count is the number of frequency domain resources included in the uplink subband.

[0261] For example, assuming the default frequency domain resource granularity is 1 RB, the uplink bandwidth BWP includes 6 RBs, and the uplink subband includes 3 RBs, then the third value can be 2. Network device 102 configures the frequency domain resources occupied by terminal 101 in different types of time units using a bitmap in the second information domain. If the bitmap is 110, then terminal 101 can use RB#0 to RB#3 of the uplink BWP to transmit uplink information in non-SBFD time units, and can use RB#0 to RB#1 of the uplink subband to transmit uplink information in SBFD time units.

[0262] Understandably, if the ratio of the number of resources in the first frequency domain to the number of resources in the second frequency domain is not an integer, the ratio can be rounded up.

[0263] For example, the third value

[0264] The above is merely an illustrative example. If the ratio of the number of resources in the first frequency domain to the number of resources in the second frequency domain is not an integer, the ratio can be rounded down. This disclosure does not limit this.

[0265] In some embodiments, after the network device 102 carries the payload in the third information domain, it sends the DCI to the terminal 101. The payload carried in the third information domain is determined based on the frequency hopping offset and frequency domain resources indicated by the first information domain and / or the second information domain, respectively. The specific determination method is not limited in this disclosure.

[0266] In step S2103, terminal 101 determines the number of bits occupied by the first information field.

[0267] In some embodiments, terminal 101 is a terminal that supports SBFD technology.

[0268] In some embodiments, terminal 101 may determine the number of bits occupied by the first information field using any of the following methods:

[0269] Method 1: Determine the number of bits occupied by the first information field based on the first quantity and the second quantity.

[0270] Method 2: Determine the number of bits occupied by the first information field based on the first quantity.

[0271] Method 3: Determine the number of bits occupied by the first information field based on the second quantity.

[0272] The method by which terminal 101 determines the number of bits occupied by the first information field is similar to the method by which network device 102 determines the number of bits occupied by the first information field, and will not be described again here.

[0273] In step S2104, terminal 101 transmits uplink information to network device 102 via frequency hopping.

[0274] In some embodiments, network device 102 may receive uplink information transmitted by frequency hopping from terminal 101.

[0275] In some embodiments, terminal 101 may transmit the uplink information via frequency hopping on time-frequency domain resources scheduled by DCI.

[0276] In some embodiments, terminal 101 may use frequency hopping to transmit the uplink information.

[0277] First, terminal 101 can determine the third frequency domain resources occupied by the Nth hop based on the type of the first time unit, the number of bits occupied by the second information domain, and the bit value of the second information domain.

[0278] The first time unit is the time unit where the Nth jump is located, where N is an odd number greater than 0, such as any value of 1, 3, 5, 7, etc.

[0279] The first time unit can be determined based on the DCI scheduling.

[0280] For example, the DCI includes a fourth information field that configures the time-domain resource location for each hop when transmitting uplink information via frequency hopping.

[0281] When the first time unit is SBFD, the terminal 101 can determine the third frequency domain resources that the network device 102 is configured to use for frequency hopping transmission of uplink information on the SBFD time unit based on the number of bits (SF) and the corresponding bit value occupied by the second information domain (which may be located in the third information domain LSB or MSB).

[0282] When the first time unit is non-SBFD, the terminal 101 can determine the third frequency domain resources used by the network device 102 for the terminal 101 to transmit uplink information by frequency hopping on the non-SBFD time unit based on the number of bits (SF) and the corresponding bit value occupied by the second information domain (which may be located in the third information domain LSB or MSB).

[0283] The third frequency domain resources occupied by terminal 101 when transmitting uplink information via frequency hopping in non-SBFD time units and SBFD time units can be the same or different. For example, uplink information PUSCH occupies RB#1 to RB#4 in both types of time units. Alternatively, considering that the frequency domain range of uplink BWP is larger than the frequency domain range of uplink subband, uplink information PUSCH can occupy RB#1 to RB#8 in non-SBFD time units and RB#1 to RB#4 in SBFD time units.

[0284] The above is merely an illustrative example, and this disclosure does not limit the scheme by which terminal 101 determines the frequency domain resources occupied by the Nth hop.

[0285] Secondly, terminal 101 can send uplink information corresponding to the Nth hop to network device 102 on the third frequency domain resources within the first time unit.

[0286] Furthermore, terminal 101 can determine the third frequency domain offset based on the type of the second time unit, the number of bits occupied by the first information domain, and the bit value of the first information domain.

[0287] The second time unit is the time unit where the (N+1)th jump occurs. The method for determining the second time unit is similar to that for determining the first time unit, and will not be repeated here.

[0288] The third frequency domain offset is used to indicate the number of frequency domain resources that the starting frequency domain resource position of the (N+1)th hop is separated from the starting frequency domain resource position of the Nth hop.

[0289] The third frequency domain offset is one of the first frequency domain offsets, or the third frequency domain offset is one of the second frequency domain offsets.

[0290] If the second time unit is an SBFD time unit, the terminal 101 can determine a first frequency domain offset whose index is equal to the bit value corresponding to the first information domain in at least one first frequency domain offset, based on the number of bits F occupied by the first information domain (which may be located in the third information domain MSB or LSB) and the corresponding bit value. The determined first frequency domain offset is the third frequency domain offset.

[0291] For example, if the first frequency domain offset #1 is 2, the first frequency domain offset #2 is 3, the first frequency domain offset #3 is 4, and the bit value corresponding to the first information domain is 10, then the terminal 101 can determine the first frequency domain offset with index 3 as the third frequency domain offset, that is, the third frequency domain offset is 4.

[0292] If the second time unit is a non-SBFD time unit, the terminal 101 can determine the third frequency domain offset based on the number of bits F occupied by the first information domain (which may be located in the third information domain, either MSB or LSB) and the corresponding bit value, in at least one second frequency domain offset, and determine a second frequency domain offset whose index is equal to the bit value corresponding to the first information domain.

[0293] For example, if the second frequency domain offset #1 is -1, the second frequency domain offset #2 is -2, the second frequency domain offset #3 is -3, and the bit value corresponding to the first information domain is 001, then the terminal 101 can determine the second frequency domain offset with index 1 as the third frequency domain offset, at which time the third frequency domain offset is -1.

[0294] Furthermore, terminal 101 can determine the starting frequency domain resource position of the (N+1)th hop based on the third frequency domain offset and the starting frequency domain resource position of the Nth hop.

[0295] For example, if N is 1, the starting frequency domain resource position of the first hop is RB#0, and the number of third frequency domain resources is 2, then the starting frequency domain resource position of the second hop is RB#2.

[0296] For example, if N is 1, the starting frequency domain resource position of the first hop is RB#10, and the number of third frequency domain resources is -2, then the starting frequency domain resource position of the second hop is RB#8.

[0297] Furthermore, terminal 101 can determine the fourth frequency domain resources occupied by the (N+1)th hop based on the type of the second time unit, the number of bits occupied by the second information domain, and the bit value of the second information domain.

[0298] When the second time unit is SBFD, the terminal 101 can determine the fourth frequency domain resources that the network device 102 is configured to use for frequency hopping transmission of uplink information in the SBFD time unit based on the number of bits occupied by the second information domain and the corresponding bit value.

[0299] When the second time unit is non-SBFD, the terminal 101 can determine the fourth frequency domain resources that the network device 102 is configured to use for frequency hopping transmission of uplink information in the non-SBFD time unit, based on the number of bits occupied by the second information domain and the corresponding bit value.

[0300] Furthermore, terminal 101 can offset the fourth frequency domain resource based on the starting frequency domain resource position of the (N+1)th hop, and determine the fifth frequency domain resource occupied by the (N+1)th hop after the offset.

[0301] For example, assuming that the fourth frequency domain resources occupied by terminal 101 in the second hop include RB#1 to RB#4, and the starting frequency domain resource position of the second hop is RB#3, then terminal 101 can determine that the fifth frequency domain resources occupied by the second hop after the offset include RB#3 to RB#6.

[0302] Finally, terminal 101 can send the uplink information corresponding to the (N+1)th hop to the network device on the fifth frequency domain resources within the second time unit.

[0303] In some embodiments, network device 102 may use a similar method to determine the third frequency domain resources in the first time unit and the fifth frequency domain resources in the second time unit, thereby receiving uplink information transmitted by frequency hopping from terminal 101 on the corresponding time-frequency domain resources.

[0304] In some embodiments, the process of network device 102 transmitting uplink information via frequency hopping through DCI scheduling terminal 101 can be as shown in Figure 2C, for example.

[0305] Assume that the second information field in the DCI indicates that when uplink information PUSCH is transmitted via frequency hopping in the SBFD time unit and the non-SBFD time unit, the frequency domain resources occupied by PUSCH are RB#2 to RB#7.

[0306] Terminal 101 can determine the number of frequency hopping transmissions as 4 according to DCI scheduling, which are located on time slots #1, #2, #3, and #4 respectively (i.e., inter-slot FH). Among them, time slots #1 to #3 are non-SBFD time slots, and time slot #4 is an SBFD time slot.

[0307] Terminal 101 can determine that the first hop and the third hop are located on RB#0 to RB#5 of time slot #1 and time slot #3 respectively, and thus transmit PUSCH on the corresponding resources.

[0308] In DCI, the first information domain occupies 2 bits, with a corresponding bit value of 10. The first frequency domain offsets #0 to #4 are 1, 2, 3, -1, and -2, respectively, and the second frequency domain offsets #0 to #3 are 0, 1, 3, -2, and -1, respectively.

[0309] Terminal 101 can determine that the third frequency domain offset is equal to the second frequency domain offset #3 in time slot #2 (non-SBFD time slot), that is, the third frequency domain offset #1 is -2. Then the frequency domain resources occupied by PUSCH #2 in time slot #2 are RB #0 to RB #5.

[0310] Terminal 101 can determine that the third frequency domain offset is equal to the first frequency domain offset #3 on time slot #4 (SBFD time slot), that is, the third frequency domain offset #2 is -1. Then the frequency domain resources occupied by PUSCH #4 on time slot #4 are RB #1 to RB #6.

[0311] Terminal 101 transmits the PUSCH according to the aforementioned time-frequency domain resources, and network device 102 receives the PUSCH on the corresponding resources.

[0333] Figure 3B is an interactive schematic diagram of an information transmission method according to an embodiment of the present disclosure. As shown in Figure 3B, the present disclosure relates to an information transmission method, which can be executed by a network device 102, and includes the following steps:

[0334] Step S3201: Determine the number of bits occupied by the first information field.

[0335] In some embodiments, reference can be made to the steps in other embodiments described before or after this embodiment, such as step S2101 in FIG2A and its optional implementation, as well as other related parts in the specification, which will not be repeated here.

[0337] In some embodiments, reference can be made to the steps in other embodiments described before or after this embodiment, such as step S2102 in FIG2A and its optional implementation, as well as other related parts in the specification, which will not be repeated here.

[0338] In some embodiments, steps S3201 to S3202 are optional, and one or more of these steps may be omitted or substituted in different embodiments.

[0339] In some embodiments, the execution order of steps S3201 to S3202 is not limited.

[0340] In the above embodiments, when different time units correspond to different frequency hopping parameters, the network device can determine the number of bits occupied by the first information field in the DCI based on a predefined method. The first information field can be used to indicate the frequency hopping offset in the frequency hopping parameters, and then send the DCI to the terminal, which improves the reliability and availability of SBFD communication.

[0341] The above process is further illustrated with examples below.

[0342] In this embodiment of the disclosure, when a network device, such as a base station, provides a terminal with FH offset lists for SBFD time units and non-SBFD time units respectively, the length of the information field in the DCI used to indicate the FH offset value can be determined.

[0343] The following content is explained using time units in terms of symbols.

[0344] In this embodiment of the disclosure, when the terminal transmits uplink channels on SBFD symbols and non-SBFD symbols, and different symbol types correspond to different FH parameters, the terminal and the base station determine the length of the information bit used to indicate FH according to a predefined method.

[0345] Terminal side:

[0346] The terminal transmits the uplink channel on SBFD symbols and non-SBFD symbols, and different symbol types correspond to different FH parameters. The terminal determines the bit length of the information field used to indicate the FH according to the following predefined method:

[0347] Method 1: The terminal determines the length of the bit used to indicate the FH offset in the DCI based on the maximum or minimum value in the FH offset list corresponding to the SBFD symbol and the FH offset list corresponding to the non-SBFD symbol.

[0348] Specifically, assume that the FH offset list for SBFD symbols contains M FH offset values, and the FH offset list for non-SBFD symbols contains N FH offset values. Based on method 1, the length of the information field in the DCI of the PUSCH used to indicate the use of FH offset for frequency hopping is F = maximum(log2(M), log2(N)) or F = minimum(log2(M), log2(N)).

[0349] When the above calculation result is not an integer, it can be:

[0350] The calculation result is rounded up or down;

[0351] Alternatively, perform a rounding up or rounding down operation on log2(M) and / or log2(N).

[0352] The terminal determines the frequency domain resources occupied by the uplink transmission within its respective symbol based on the bits in the FDRA field after removing the F bits MSB used to indicate the FH offset.

[0353] When the information bits used to indicate the uplink transmission frequency domain location cannot indicate all available uplink RBs according to the preset frequency domain granularity, the frequency domain resource indication method is determined according to the following method:

[0354] Method 1-1 introduces a scaling factor k to determine the frequency domain allocation granularity for the corresponding symbol type.

[0355] For example, k is determined according to the following formula 1:

[0356]

[0357] Wherein, UL BWP refers to the number of frequency domain resources included in the uplink BWP, and UL subband refers to the number of frequency domain resources included in the uplink subband.

[0358] Methods 1-2 determine the frequency domain resources used for uplink transmission within a subset of available frequency domain resources based on the default frequency domain resource allocation granularity.

[0359] In this method, the total length of the FDRA remains unchanged. Specifically, the FDRA field used to indicate uplink transmission on SBFD symbols and non-SBFD symbols has the same length and is not affected by the field used to indicate the FH offset information.

[0360] Method 2: Determine the bit length in the DCI used to indicate the FH offset based on the FH offset list corresponding to the non-SBFD symbol.

[0361] Specifically, assume that the FH offset list for SBFD symbols contains M FH offset values, and the FH offset list for non-SBFD symbols contains N FH offset values. Based on method 1, the length of the information field in the DCI that indicates the use of FH offset for frequency hopping in the PUSCH scheduling or activation is F = log2(N).

[0362] When the above calculation result is not an integer, the calculation result can be rounded up or down.

[0363] Specifically, the terminal determines the frequency domain resources occupied by the uplink transmission within its respective symbol based on the bits in the FDRA field after removing the F bits MSB used to indicate the FH offset.

[0364] In this method, the total length of the FDRA remains unchanged. Specifically, the FDRA field used to indicate uplink transmission on SBFD symbols and non-SBFD symbols has the same length and is not affected by the field used to indicate the FH offset information.

[0365] Method 3: Determine the bit length in the DCI used to indicate the FH offset based on the FH offset list corresponding to the SBFD symbol.

[0366] Specifically, assume that the FH offset list for SBFD symbols contains M FH offset values, and the FH offset list for non-SBFD symbols contains N FH offset values. Based on method 3, the length of the information field in the DCI that indicates the use of FH offset for frequency hopping in the PUSCH scheduling or activation is F = log2(M).

[0367] When the above calculation result is not an integer, the calculation result can be rounded up or down.

[0368] The terminal determines the frequency domain resources occupied by the uplink transmission within its respective symbol based on the bits in the FDRA field after removing the F bits MSB used to indicate the FH offset.

[0369] In this method, the total length of the FDRA remains unchanged. Specifically, the FDRA field used to indicate uplink transmission on SBFD symbols and non-SBFD symbols has the same length and is not affected by the field used to indicate the FH offset information.

[0370] In this embodiment, it is assumed that PUSCH is enabled for either inter-slot frequency hopping or intra-slot frequency hopping.

[0371] In this embodiment, it is assumed that the PUSCH is transmitted on different symbol types, including SBFD symbol and non-SBFD symbol. SBFD symbol means OFDM symbol configured with UL subband.

[0372] In this embodiment, the PUSCH includes Type2 CG PUSCH, PUSCH scheduled by DCI and with repetition enabled, multi-PUSCH scheduled by a single DCI, etc.

[0373] In this embodiment, the symbols of different symbol types correspond to different FH parameters, including at least the FH offset of the frequency domain interval between the first hop and the second hop.

[0374] In this embodiment, the terminal is a terminal that supports SBFD technology.

[0375] This disclosure also proposes an apparatus (also referred to as a communication device, etc.) for implementing any of the above methods. For example, an apparatus is proposed that includes units or modules for implementing the steps performed by the terminal in any of the above methods. Furthermore, another apparatus is proposed that includes units or modules for implementing the steps performed by a network device (e.g., an access network device, a core network functional node, a core network device, etc.) in any of the above methods.

[0376] It should be understood that the division of units or modules in the above device is only a logical functional division. In actual implementation, they can be fully or partially integrated into a single physical entity, or they can be physically separated. Furthermore, the units or modules in the device can be implemented by a processor calling software: for example, the device includes a processor connected to a memory containing instructions. The processor calls the instructions stored in the memory to implement any of the above methods or to implement the functions of the units or modules in the above device. The processor can be, for example, a general-purpose processor, such as a Central Processing Unit (CPU) or a microprocessor, and the memory can be internal or external to the device. Alternatively, the units or modules in the device can be implemented in the form of hardware circuits. The functionality of some or all of the units or modules can be achieved through the design of these hardware circuits, which can be understood as one or more processors. For example, in one implementation, the hardware circuit is an application-specific integrated circuit (ASIC). The functionality of some or all of the units or modules is achieved through the design of the logical relationships between the components within the circuit. In another implementation, the hardware circuit can be implemented using a programmable logic device (PLD). Taking a field-programmable gate array (FPGA) as an example, it can include a large number of logic gates. The connection relationships between the logic gates are configured through configuration files, thereby achieving the functionality of some or all of the units or modules. All units or modules of the above device can be implemented entirely through processor-called software, entirely through hardware circuits, or partially through processor-called software with the remaining parts implemented through hardware circuits.

[0377] In this embodiment, the processor is a circuit with signal processing capabilities. In one implementation, the processor can be a circuit with instruction read and execute capabilities, such as a Central Processing Unit (CPU), a microprocessor, a graphics processing unit (GPU) (which can be understood as a microprocessor), or a digital signal processor (DSP). In another implementation, the processor can implement certain functions through the logical relationships of hardware circuits. The logical relationships of the aforementioned hardware circuits are fixed or reconfigurable. For example, the processor is a hardware circuit implemented using an application-specific integrated circuit (ASIC) or a programmable logic device (PLD), such as an FPGA. In a reconfigurable hardware circuit, the process of the processor loading a configuration document and configuring the hardware circuit can be understood as the process of the processor loading instructions to implement the functions of some or all of the above units or modules. Furthermore, it can also be a hardware circuit designed for artificial intelligence, which can be understood as an ASIC, such as a Neural Network Processing Unit (NPU), a Tensor Processing Unit (TPU), or a Deep Learning Processing Unit (DPU).
