### Example Embodiment

[0203] The technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are part of the embodiments of the present invention, not all of them. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative work shall fall within the protection scope of the present invention.

[0204] With the development and change of mobile communication service requirements, organizations such as ITU and 3GPP have begun to study new wireless communication systems (for example, 5G NR, 5Generation New RAT). A new frame structure is defined in the new wireless communication system and supports different baseband parameters (numerology, including parameters such as subcarrier spacing). For different baseband parameters, it is defined that the length of a subframe is always 1ms, and a subframe contains A slots, corresponding to different baseband parameters, the number of A may be different, so that the length of a subframe is 1ms. For different baseband parameters, a slot can contain 7 or 14 symbols (such as OFDM, DFT-S-OFDM or PDMA symbols). A slot can have multiple slot structures/formats, and different slot structures/formats correspond to different uplink and downlink resource divisions. For example, all symbols in a slot can be used for downlink transmission, that is, DL only slot, or all of them can be used for uplink transmission. , Namely UL only slot, can also be used partly for uplink transmission and partly for downlink transmission, namely DL+UL slot. The slot structure/format may be notified to the terminal through RRC signaling in a semi-static manner, or may be notified to the terminal in a dynamic manner, for example, through multicast public signaling (Group Common PDCCH), so as to dynamically change the slot structure.

[0205] As the number of uplink symbols contained in a slot may change, the 5G NR system defines two types of NR-PUCCH, long NR-PUCCH and short NR-PUCCH. Among them, long NR-PUCCH can occupy 4 to 14 in a slot. For transmission of two symbols, UCI and Reference Signal (RS, Reference Signal) are transmitted in TDM mode, that is, UCI and RS occupy different symbols for transmission. In order to improve the uplink transmission performance, the long NR-PUCCH can use the frequency hopping structure in the multiple symbols occupied to obtain the frequency domain diversity gain. Of course, the frequency hopping structure may not be used to increase the multi-user multiplexing capacity. A format in the NR PUCCH can be used to carry 1 or 2 bits of information transmission. This format can be used to obtain a modulation symbol after BPSK/QPSK modulation of the transmission information. This modulation symbol is used for each UCI that is occupied by PUCCH transmission. Repeated transmission on the symbol of each symbol. On each symbol, the modulation symbol is carried on a CAZAC base sequence or CG base sequence that has passed CS for transmission. Different symbols can also be spread by time-domain orthogonal sequences to support larger Multi-user multiplexing capacity. Based on this, the embodiment of the present invention provides a PUCCH transmission method, which can determine the CS value on each symbol of the PUCCH of different lengths, so as to realize the transmission of the NR PUCCH of different lengths.

[0206] See figure 1 , figure 1 It is a schematic diagram of a network structure applicable to the embodiment of the present invention, such as figure 1 As shown, it includes a mobile communication terminal (User Equipment, UE) 11 and a network side device 12, where the mobile communication terminal 11 may be a mobile phone, a tablet computer (Tablet Personal Computer), a laptop computer (Laptop Computer), or a personal digital assistant. Terminal-side devices such as personal digital assistant (PDA for short), Mobile Internet Device (MID), or Wearable Device (Wearable Device). It should be noted that the mobile communication terminal is not limited in the embodiment of the present invention 11 specific types. The network side device 12 may be a base station, such as a macro station, LTE eNB, 5G NRNB, etc.; the network side device 12 may also be a small station, such as a low power node (LPN: low power node) pico, femto, etc., or a network The side device 12 may be an access point (AP, access point); the base station may also be a network node composed of a central unit (CU, central unit) and multiple transmission reception points (TRP, Transmission Reception Points) managed and controlled by it. It should be noted that the specific type of the network side device 12 is not limited in the embodiment of the present invention.

[0207] See figure 2 , figure 2 It is a flowchart of a PUCCH transmission method provided by an embodiment of the present invention, such as figure 2 As shown, including the following steps:

[0208] Step 201, according to the initial cyclic shift CS parameter and at least the random value associated with the symbol number, determine the target CS parameter corresponding to each symbol.

[0209] The PUCCH transmission method provided by the embodiment of the present invention is mainly applied to a mobile communication terminal, and is used to determine the CS parameter corresponding to each symbol occupied by the PUCCH.

[0210] In this step, each of the foregoing symbols is a symbol occupied by PUCCH transmission, and the symbol may be an access symbol such as OFDM (Orthogonal Frequency Division Multiplexing, Orthogonal Frequency Division Multiplexing) or DFT-S-OFDM. The above-mentioned initial CS parameters can be pre-arranged by agreement or configured by the network side. The specific configuration method can be set according to actual needs. For example, the initial CS parameters are pre-configured by the network side device to the mobile device through high-level signaling. The CS parameter of the communication terminal, or the CS parameter indicated by the network-side device through Downlink Control Information (DCI), where the CS parameter indicated by the DCI is a high-level signaling pre-configured to the multiple sets of the mobile communication terminal CS parameter in a set.

[0211] In this embodiment, the aforementioned random value may only include the random value associated with the symbol number, and may also include the random value associated with the symbol number and other random values. The target parameters that need to be associated with the other random values can be set according to actual needs. For example, in this embodiment, the target parameter may be numbered in time units. Specifically, the definition of the time unit can be defined according to actual needs. For example, in this embodiment, the time unit can be defined in the following three ways:

[0212] First: The time unit includes one or more time slots.

[0213] Second: The time unit includes 14 symbols.

[0214] Third: The time unit includes one subframe.

[0215] In this embodiment, the target CS parameter corresponding to each symbol can be determined according to the aforementioned random value and the initial CS parameter configured on the network side.

[0216] Step 202: Send PUCCH according to the target CS parameter.

[0217] In this step, after determining the target CS parameter corresponding to each symbol, the CS value corresponding to each symbol can be calculated based on the target CS parameter, so as to obtain the transmission sequence of the PUCCH according to the CS value, so as to perform PUCCH transmission.

[0218] In this way, in the embodiment of the present invention, the target CS parameter corresponding to each symbol is determined according to the initial cyclic shift CS parameter and at least the random value associated with the symbol number; the PUCCH is sent according to the target CS parameter. Since the embodiment of the present invention adds at least the random value associated with each symbol number to the initial CS parameter for calculation, it can be obtained that the target CS parameter corresponding to each symbol is different, and the NR PUCCH of different length is determined CS value on each symbol. Therefore, in the embodiment of the present invention, it can be ensured that the CS values on different symbols are as different as possible to achieve interference randomization, improve PUCCH transmission performance, and ensure the CS values of NR PUCCHs with different lengths on the same symbol. The acquisition method is the same to support multiplexing transmission of NR PUCCHs with different lengths in the same RB, so as to reduce the system PUCCH resource overhead.

[0245] In one embodiment, Can be used in the above formula You can also directly replace it with 12.

[0246] With regard to the above-mentioned implementation manners 1 to 6, the implementation process is described in detail through two different embodiments.

[0247] Specifically, in an embodiment, the aforementioned random value includes a random value associated with a symbol number and a random value associated with a time unit number. At this point, you can follow Calculate the CS value corresponding to each symbol.

[0248] In this embodiment, assuming that the pseudo-random sequence c(i) is initialized with ID=3, assuming that ns=0, a time unit is a time slot, and contains 14 symbols, that is, the symbol number l ranges from 0 to 13, then according to We can get n on each symbol in time slot ns=0 cs (n s ,l) values are [65,106,89,191,68,73,63,48,18,84,252,230,149,236], assuming that PUCCH occupies 7 symbols, and on the symbols with symbol number l=7-13, assuming Δ shift =2, then:

[0249] According to the above embodiment 1: Assuming CS init According to Δ shift To configure, that is, if Δ shift = 2, then CS init It can only be selected from [0, 2, 4, 6, 8, 10], or [1, 3, 5, 7, 9, 11]; for example, the base station configures a CS for UE1 through signaling init =1, configure a CS for UE2 init =3; according to Follow UE1's CS init The CS parameters corresponding to the symbols of the symbol number l from 0 to 13 are calculated as [6,11,6,0,9,2,4,1,7,1,1,3,6,9], whichever is l = the CS parameter corresponding to 7~13 or directly calculate the CS parameter corresponding to the symbol occupied by PUCCH according to l=7~13 [1,7,1,1,3,6,9], and then according to Obtain the CS value of each symbol occupied by the PUCCH of UE1, and UE1 obtains the transmission sequence on the symbol occupied by the PUCCH it transmits according to the CS value, and transmits; similarly, according to the CS value of UE2 init The CS parameters corresponding to the symbols from 0 to 13 of the symbol number l are calculated as [8,1,8,2,11,4,6,3,9,3,3,5,6,11], whichever is l = the CS parameter corresponding to 7~13 or directly calculate the CS parameter corresponding to the symbol occupied by PUCCH according to l=7~13 [3,9,3,3,5,6,11], and then according to The CS value of each symbol occupied by the PUCCH of UE2 is obtained, and UE2 obtains the transmission sequence on the symbol occupied by the PUCCH it transmits according to the CS value, and performs transmission.

[0250] According to the above implementation mode 3: Assume CS init According to Δ shift To configure, that is, if Δ shift = 2, then CS init It can only be selected from the two groups of [0, 2, 4, 6, 8, 10], or [1, 3, 5, 7, 9, 11]. If one parameter in a group is selected for a UE, Another UE that needs to use the same resource for multiplexing transmission with the UE needs to be selected in the same group; for example, the base station configures a CS for UE1 through signaling init =1, configure a CS for UE2 init =3; in accordance with the Calculating the CS parameter on each symbol is equivalent to first according to Δ shift CS to be configured init Normalize to 0~12/Δ shift That is, the value of 0 to 5, and then the CS randomization is performed based on the normalized CS parameter; that is, according to the CS of UE1 init The CS parameters corresponding to the symbols from 0 to 13 of the symbol number l are calculated as [5,10,5,11,8,1,3,0,6,0,0,2,5,8], whichever is l = the CS parameter corresponding to 7~13 or directly calculate the CS parameter corresponding to the symbol occupied by PUCCH according to l=7~13 [0,6,0,0,2,5,8], and then according to Obtain the CS value of each symbol occupied by the PUCCH of UE1, and UE1 obtains the transmission sequence on the symbol occupied by the PUCCH it transmits according to the CS value, and transmits; similarly, according to the CS value of UE2 init The CS parameters corresponding to the symbols of the symbol number l from 0 to 13 are calculated as [7,0,7,1,10,3,5,2,8,2,2,4,7,10], whichever is l = the CS parameter corresponding to 7~13 or directly calculate the CS parameter corresponding to the symbol occupied by PUCCH according to l=7~13 [2,8,2,2,4,7,10], and then according to The CS value of each symbol occupied by the PUCCH of UE2 is obtained, and UE2 obtains the transmission sequence on the symbol occupied by the PUCCH it transmits according to the CS value, and performs transmission.

[0251] According to the above implementation mode 5: assuming the configured CS init According to Δ shift The normalized value, namely Δ shift =1, CS configured by gNB init Can be 0~11, Δ shift =2, CS configured by gNB init It is 0~5. The advantage of this indication is that it can be based on Δ shift Size to adjust CS init For example, the range of 0-11 requires a 4-bit indicator, the range of 0-5 requires a 3-bit indicator, and so on; at this time, it is based on a normalized CS init Choose whether to use {0,2,4,6,8,10} or {1,3,5,7,9,11} on a symbol, depending on n cs (n s , 1) parity value; for example, the base station configures a CS for UE1 through signaling init =1, configure a CS for UE2 init =3; according to the formula Follow UE1's CS init The CS parameters corresponding to the symbols of the symbol number l from 0 to 13 are calculated as [7,0,7,1,10,3,5,2,8,2,2,4,7,10], whichever is l = the CS parameter corresponding to 7~13 or directly calculate the CS parameter corresponding to the symbol occupied by PUCCH according to l=7~13 [2,8,2,2,4,7,10], and then according to Obtain the CS value of each symbol occupied by the PUCCH of UE1, and UE1 obtains the transmission sequence on the symbol occupied by the PUCCH it transmits according to the CS value, and transmits; similarly, according to the CS value of UE2 init The CS parameters corresponding to the symbols of the symbol number l from 0 to 13 are calculated as [11,4,11,5,2,7,9,6,0,6,6,8,11,2], whichever is l = the CS parameter corresponding to 7~13 or directly calculate the CS parameter corresponding to the symbol occupied by PUCCH according to l=7~13 [6,0,6,6,8,11,2], and then according to The CS value of each symbol occupied by the PUCCH of UE2 is obtained, and UE2 obtains the transmission sequence on the symbol occupied by the PUCCH it transmits according to the CS value, and performs transmission.

In addition, the number of n on the same symbol between different cells cs (n s , l) The value is different, so that the CS value on the same symbol between different cells can be different, and the purpose of randomization of interference between different cells can be achieved. Among them, when any one of ns and ID changes, n calculated in the above embodiment cs (n s ,l) The value will also change, so the CS value on each symbol will also change.

[0256] According to the above embodiment 4: Assume CS init According to Δ shift To configure, that is, if Δ shift = 2, then CS init It can only be selected from the two groups [1, 3, 5, 7, 9, 11] and [0, 2, 4, 6, 8, 10]. If one parameter in a group is selected for a UE, the other A UE that needs to use the same resource for multiplexing transmission with the UE needs to be selected in the same group; for example, the base station configures a CS for UE1 through signaling init =1, configure a CS for UE2 init =3; in accordance with the Calculating the CS parameter on each symbol is equivalent to first according to Δ shift CS to be configured init Normalize to 0~12/Δ shift That is, the value of 0 to 5, and then the CS randomization is performed based on the normalized CS parameter; that is, according to the CS of UE1 init The CS parameters corresponding to the symbols from 0 to 13 of the symbol number l are calculated as [5,10,5,11,8,1,3,0,6,0,0,2,5,8], whichever is l = the CS parameter corresponding to 7~13 or directly calculate the CS parameter corresponding to the symbol occupied by PUCCH according to l=7~13 [0,6,0,0,2,5,8], and then according to Obtain the CS value of each symbol occupied by the PUCCH of UE1, and UE1 obtains the transmission sequence on the symbol occupied by the PUCCH it transmits according to the CS value, and transmits; similarly, according to the CS value of UE2 init The CS parameters corresponding to the symbols of the symbol number l from 0 to 13 are calculated as [7,0,7,1,10,3,5,2,8,2,2,4,7,10], whichever is l = the CS parameter corresponding to 7~13 or directly calculate the CS parameter corresponding to the symbol occupied by PUCCH according to l=7~13 [2,8,2,2,4,7,10], and then according to The CS value of each symbol occupied by the PUCCH of UE2 is obtained, and UE2 obtains the transmission sequence on the symbol occupied by the PUCCH it transmits according to the CS value, and performs transmission.
