[0003] In the related art, a UE (User Equipment) can only have one SR (Scheduling Request) resource at the same time, and the SR resource can only be used to transmit one type of SR. When the UE has uplink buffer data to be sent, i.e., the UE needs to send an UL-SR (UpLink-Scheduling Request), and the UE also needs to send other types of SR to the base station at the same time, such as a BFRQ (Beam Failure Recovery Request), the UE can only transmit one of the BFR_SR and the UL_SR, resulting in a delay in the transmission of the other SR.

[0056] The exemplary embodiments will be described in detail herein with reference to the attached drawings. In the following description, the same numbers refer to the same or similar elements throughout the drawings. The embodiments described in the following exemplary embodiments are not meant to represent all embodiments consistent with the present disclosure. Rather, they are merely examples of apparatuses and methods consistent with some aspects of the present disclosure as detailed in the appended claims.

[0057] Figure 1 is a flow chart of a scheduling request transmission method according to an exemplary embodiment, the method is applied to a terminal, i.e. the method can be performed by a terminal, as shown in Figure 1 the method comprises:

[0058] In step 101, before transmitting an SR to a base station through a PUCCH (Physical Uplink Control Channel), according to the SR and the PUCCH format used to transmit the SR, a preset parameter used to generate an SR sequence is determined, the preset parameter corresponds to the transmission mode of the SR and the PUCCH format used to transmit the SR, wherein the transmission mode of the SR includes transmitting a first SR, transmitting a second SR, and transmitting the first SR and the second SR at the same time, the first SR and the second SR are different types of SRs.

[0059] The PUCCH format used to transmit the SR is the PUCCH format indicated by the base station for the terminal to transmit the SR.

[0060] In one implementation, the correspondence between the preset parameter, the transmission mode of the SR, and the PUCCH format can be indicated by the base station to the terminal, or it can be pre-negotiated by the two.

[0061] In an implementation, different PUCCH formats can correspond to different types of preset parameters. For example, assuming the preset parameters include a preset cyclic shift and an information block, the PUCCH formats can include a first predefined format and a second predefined format. The preset parameters corresponding to the first predefined format can be the cyclic shift, and the preset parameters corresponding to the second predefined format can be the information block. For example, the first predefined format can be referred to as PUCCH format 0b, and the SR sequence generation manner and resource mapping manner of the first predefined format can be the same as those of PUCCH format 0. For example, the second predefined format can be referred to as PUCCH format 1b, and the SR sequence generation manner and resource mapping manner of the second predefined format can be the same as those of PUCCH format 1.

[0062] In an implementation, the transmission manner of the SR can be determined according to the information currently required to be transmitted by the terminal. For example, when the terminal currently only needs to send the first SR to the base station, the transmission manner of the SR is determined to be the transmission of the first SR. When the terminal currently only needs to send the second SR to the base station, the transmission manner of the SR is determined to be the transmission of the second SR. When the terminal currently needs to send the first SR and the second SR to the base station at the same time, the transmission manner of the SR is determined to be the simultaneous transmission of the first SR and the second SR.

[0063] In step 102, an SR sequence is generated according to the determined preset parameters.

[0064] In step 103, the generated SR sequence is sent to the base station.

[0065] According to the scheduling request transmission method of the embodiment, the terminal can determine the preset parameters used to generate the SR according to the SR sent to the base station and the format of the PUCCH channel used to send the SR. Since the preset parameters correspond to the transmission manner of the SR and the PUCCH format used to send the SR, and the transmission manner of the SR includes the transmission of one SR or the simultaneous transmission of two different types of SRs, the terminal can achieve the purpose of simultaneously transmitting two SRs without additional SR resources.

[0066] Figure 2 is a flowchart of a scheduling request transmission method according to an example embodiment, as shown in Figure 2As shown, in the method, the preset parameter can include a preset cyclic shift and a preset information block, based on which, the preset parameter used for generating the SR sequence is determined according to the SR and the PUCCH format used for transmitting the SR, which can include: in step 104, when the PUCCH format used for transmitting the SR is a first predefined format, the preset cyclic shift corresponding to the transmission mode of the SR is determined as the preset parameter used for generating the SR sequence. When the PUCCH format used for transmitting the SR is the first predefined format, the correspondence between various different scenarios of the terminal transmitting the SR to the base station and the cyclic shift can be as shown in Table 1.

[0067] Table 1

[0068] Whether to send UL_SR Whether to send BFR_SR Sequence cyclic shift Scenario one Yes Yes m cs = 0 Scenario two Yes No m cs = 4 Scenario three No Yes m cs = 8 Scenario four No No N / A

[0069] Scenario one in Table 1 corresponds to the transmission mode of simultaneously transmitting UL_SR and BFR_SR, scenario two corresponds to the transmission mode of transmitting UL_SR (which is an example of the first SR), scenario three corresponds to the transmission mode of transmitting BFR_SR (which is an example of the second SR), and BFR_SR is used to represent BFRQ. Scenario four indicates that no data is transmitted on the SR resource. As can be seen from Table 1, when the transmission mode of the SR is to simultaneously transmit UL_SR and BFR_SR, i.e., the terminal simultaneously transmits UL_SR and BFR_SR to the base station, the value of the cyclic shift m cs used for generating the SR sequence is 0; when the transmission mode of the SR is to only transmit UL_SR, i.e., the terminal only transmits UL_SR to the base station, the value of the cyclic shift m cs used for generating the SR sequence is 4; when the transmission mode of the SR is to only transmit BFR_SR, i.e., the terminal only transmits BFR_SR to the base station, the value of the cyclic shift used for generating the SR sequence is 8; when the terminal does not transmit UL_SR and BFR_SR, the terminal does not take any operation. It should be noted that, in the case where the values of m cs corresponding to different SR transmission modes can be different, the value of m cs may be any integer between 0 and 11.

[0070] Figure 3 is a flowchart of a scheduling request transmission method according to an example embodiment, as Figure 3As shown, in the method, generating the SR sequence according to the determined preset parameter can include: in step 105, generating the SR sequence according to the preset cyclic shift, the initial cyclic shift corresponding to the first preset format, and the time domain position of the SR sequence in the SR resource. Wherein, the initial cyclic shift can be an initial cyclic shift corresponding to the first predefined format pre-allocated by the base station for the terminal, or can be an initial cyclic shift corresponding to the first predefined format pre-negotiated by the base station and the terminal. When the terminal transmits the SR to the base station using the PUCCH format 0b format, the SR sequence can be generated using the SR sequence generation manner defined in the PUCCH format 0. Wherein, the initial cyclic shift can be used to distinguish different users / terminals, and the cyclic shift can be used to distinguish specific information transmitted by the terminal, for example, can be used to distinguish whether the information transmitted by the terminal is an uplink SR or a BFRQ. The SR sequence can support up to 12 cyclic shifts, and each terminal can include the above three SR transmission modes, so that up to four terminals can simultaneously transmit PUCCH format 0b messages on an RB (Resource Block, resource block), and it is necessary to ensure that the combination of all cyclic shifts and initial cyclic shifts of the four terminals is not the same.

[0071] Figure 4 is a flowchart of a scheduling request transmission method according to an exemplary embodiment, in which the preset parameter can include a preset cyclic shift and a preset information block, such as Figure 4 As shown, in the method, determining the preset parameter used to generate the SR sequence according to the SR and the PUCCH format used to transmit the SR can include: in step 106, when the used PUCCH format is a second predefined format, determining that the preset information block corresponding to the transmission mode of the SR is the preset parameter used to generate the SR sequence, and the preset information block includes at least two bits. The second predefined format can be referred to as PUCCH format 1b, for example. When the PUCCH format used to transmit the SR is the second predefined format, the correspondence between the various different scenarios of the terminal transmitting the SR to the base station and the information block can be as shown in Table 2.

[0072] Table 2

[0073]

[0074]

[0075] The scenario one in Table 2 corresponds to the transmission mode of transmitting UL_SR and BFR_SR at the same time, the scenario two corresponds to the transmission mode of transmitting UL_SR, the scenario three corresponds to the transmission mode of transmitting BFR_SR, and the scenario four indicates that no data is transmitted on the SR resource. As can be seen from Table 2, when the transmission mode of the SR is to transmit UL_SR and BFR_SR at the same time, i.e., the terminal needs to transmit UL_SR and BFR_SR to the base station at the same time, the value of the information block used to generate the SR sequence is 10; when the transmission mode of the SR is to transmit only UL_SR, i.e., the terminal needs to transmit only UL_SR to the base station, the value of the information block used to generate the SR sequence is 00; when the transmission mode of the SR is to transmit only BFR_SR, i.e., the terminal needs to transmit only BFR_SR to the base station, the value of the information block used to generate the SR sequence is 11; and when the terminal does not transmit UL_SR and BFR_SR, the terminal does not take any operation.

[0076] Figure 5 is a flowchart of a scheduling request transmission method according to an exemplary embodiment, as Figure 5As shown, in the method, generating the SR sequence according to the preset parameter can include: in step 107, modulating the preset information block to obtain a symbol, for example, when the preset information block is a one-bit information block, the information block can be modulated by BPSK (Binary Phase Shift Keying), and when the preset information block is a two-bit information block, the information block can be modulated by QPSK (Quadrature Phase Shift Keying); in step 108, calculating an original sequence according to the time domain position of the SR sequence in the SR resource, the initial cyclic shift corresponding to the second predefined format, and a preset orthogonal sequence, for example, the original sequence can be generated by using the generation mode of the original sequence defined in the PUCCH format 1. The initial cyclic shift corresponding to the second predefined format can be the initial cyclic shift corresponding to the second predefined format allocated by the base station to the terminal in advance, or can be the initial cyclic shift corresponding to the second predefined format agreed by the base station and the terminal in advance; in step 109, multiplying the original sequence by the modulated symbol to obtain the SR sequence. The preset information block can be the preset information block corresponding to the second predefined format allocated by the base station to the terminal in advance, or can be the preset information block corresponding to the second predefined format agreed by the base station and the terminal in advance; the orthogonal sequence can be the sequence allocated by the base station to the terminal by RRC (Radio Resource Control) signaling or MAC CE (Medium / Media Access Control) CE (Control Element) signaling for the terminal to generate the original base sequence.

[0077] Figure 6 is a flow chart of a scheduling request transmission method according to an exemplary embodiment, as shown in Figure 6 the method is based on the method shown in Figure 1 the method can further include: in step 110, receiving the control signaling sent by the base station, the control signaling indicating the type of the preset parameter corresponding to each predefined PUCCH format, and the value of the preset parameter corresponding to the transmission mode of each SR under each predefined PUCCH format. For example, the control signaling can indicate the content in Table 1 and / or Table 2. In addition, the control signaling can also include the identifier of the terminal. The control signaling can be RRC signaling or MAC CE signaling. It should be noted that the execution order between step 110 and steps 101, 102 and 103 is not limited in the embodiment, Figure 6 only one case where step 110 is executed before steps 101, 102 and 103 is shown.

[0078] In an implementation, the terminal can pre-store the type of preset parameters corresponding to each predefined PUCCH format, and the value of preset parameters corresponding to the transmission mode of each SR under each predefined PUCCH format, for example, the terminal can pre-store the content in Table 1 and / or Table 2. Correspondingly, since the base station needs to determine the content requested by the terminal according to the received SR sequence transmitted by the terminal, the base station can also store these contents. Alternatively, the terminal and the base station use a communication protocol to transmit SR, and the communication protocol specifies these contents.

[0079] In an implementation, the first SR can be an uplink SR, and the second SR can be a BFRQ. For example, when the SR resource of the terminal comes periodically and the SR needs to be transmitted through PUCCH format 0b, the terminal can determine the m cs When the terminal currently needs to transmit UL_BFR and BFR_SR, the terminal considers m cs to be 0; when the terminal only needs to send UL_BFR to the base station, the terminal considers m cs to be 4; when the terminal only needs to send BFR_SR to the base station, the terminal considers m cs to be 8. When the terminal does not send UL_BFR and BFR_SR, the terminal does not take any operation. The terminal calculates the SR sequence to be transmitted according to the obtained m cs , the time domain position of the SR resource, and m0 corresponding to PUCCH format 0b, and sends the generated SR sequence to the base station on the SR resource. The uplink SR can be a request for applying for uplink transmission resource to the base station, and the BFRQ can be a request for informing the base station that the terminal currently has a partial beam failure event.

[0080] Figure 7 is a flowchart of a scheduling request transmission method according to an example embodiment, which is applied to a base station, i.e., the method can be executed by the base station. As shown in Figure 7 , the method comprises:

[0081] In step 701, an SR sequence is obtained.

[0082] For example, the base station can obtain the SR sequence by detecting the sequence transmitted on the SR resource.

[0083] In step 702, a preset parameter used for generating the SR sequence is determined according to the PUCCH format used for transmitting the SR sequence and the SR sequence, the preset parameter corresponding to the transmission mode of the SR and the PUCCH format used for transmitting the SR sequence, the transmission mode of the SR including transmitting a first SR, transmitting a second SR, and simultaneously transmitting the first SR and the second SR, the first SR and the second SR being different types of SRs.

[0084] In an implementation, the preset parameter used for generating the received SR sequence can be determined according to a correspondence between the preset parameter, the transmission mode of the SR, and the PUCCH format used for transmitting the SR sequence. The base station can pre-store the correspondence, and the base station can configure the correspondence for the terminal through RRC signaling or MAC CE signaling. In addition, the correspondence can also be pre-negotiated by the base station and the terminal.

[0085] In step 703, the content requested by the terminal that transmits the SR sequence is determined according to the determined preset parameter.

[0086] In an implementation, since the preset parameter corresponds to the transmission mode of the SR, and the above three transmission modes of the SR correspond to the type of the transmitted SR, the base station can determine the type of the SR transmitted by the terminal that transmits the SR sequence after obtaining the preset parameter used for generating the SR sequence. For example, the SR can be an uplink SR, and can also be a BFRQ. After obtaining the type of the SR, the base station can determine the content requested by the terminal that transmits the SR sequence.

[0087] Through the scheduling request transmission method of the embodiment, the base station can determine the preset parameter used for generating the SR sequence according to the received SR sequence and the PUCCH format used for transmitting the SR sequence, so as to determine the content requested by the terminal that transmits the SR based on the preset parameter. Since the transmission mode of the SR includes transmitting one SR or simultaneously transmitting two different types of SRs, the base station can identify two different types of SRs simultaneously transmitted by the terminal.

[0088] Figure 8 is a flowchart of a scheduling request transmission method according to an example embodiment, in which the preset parameter includes a preset cyclic shift and a preset information block, such as Figure 8As shown, determining the preset parameter used for generating the SR sequence according to the PUCCH format used for transmitting the SR sequence and the SR sequence can include: in step 704, using at least one preset cyclic shift to generate at least one reference SR sequence when the PUCCH format used for transmitting the SR sequence is a first predefined format; in step 705, comparing the consistency of each generated reference SR sequence with the received SR sequence; and in step 706, determining that the preset cyclic shift corresponding to the reference SR sequence with the highest consistency with the received SR sequence is the preset cyclic shift used for generating the received SR sequence. The at least one cyclic sequence can be part or all of the 12 cyclic shifts that the SR sequence can support, for example, it can be the three cyclic shifts shown in Table 1 above. Since different cyclic shifts correspond to different transmission modes of SR, and each transmission mode specifies the type of SR to be transmitted, the base station can know the type of SR to be transmitted according to the determined cyclic shift, and after knowing the type of SR, the base station can know the content requested by the terminal that generates the SR. For example, when the SR is an uplink SR, the base station knows that the terminal needs to request uplink transmission resources, and when the SR is a BFRQ, the base station knows that the terminal requests beam failure recovery.

[0089] Figure 9 is a flowchart of a scheduling request transmission method according to an exemplary embodiment, as Figure 9As shown, determining the preset parameters used to generate the SR sequence based on the PUCCH format used for transmitting the SR sequence and the SR sequence may include: In step 707, when the PUCCH format used for transmitting the SR sequence is a second predefined format, the received SR sequence is correlated with the original sequence to obtain a target value. For example, the correlation between the received SR sequence and the original sequence can be calculated, and this correlation can be used as the target value; Step 708: Map the target value onto the first constellation point in the constellation diagram; Step 709: Determine the second constellation point closest to the first constellation point among all standard constellation points in the constellation diagram. Each standard constellation point corresponds to a preset information block, which includes at least two bits. Each standard constellation point is the position of the preset information block on the constellation diagram after modulation. For example, when the preset information block is two bits, each standard constellation point is the position of the preset information block on the constellation diagram after QPSK modulation. Step 710: Determine the preset information block corresponding to the second constellation point as the information block used to generate the SR sequence. Since different information blocks correspond to different SRs, and each transmission method specifies the type of SR to be transmitted, the base station can know the type of SR to be transmitted based on the information block obtained. After knowing the type of SR, the base station can know the content requested by the terminal that sent the SR. For example, when the SR is an uplink SR, the base station knows that the terminal needs to request uplink transmission resources. When the SR is a BFRQ, the base station knows that the terminal requests beam fault recovery.

[0090] Figure 10 This is a flowchart illustrating a scheduling request transmission method according to an exemplary embodiment, such as... Figure 10 As shown, the method is in Figure 7 The method shown may further include, in step 711, sending control signaling to the terminal. This control signaling indicates the type of preset parameters corresponding to each predefined PUCCH format, and the values ​​of preset parameters corresponding to various SR transmission methods under each predefined PUCCH format. For example, the control signaling may indicate that the preset parameter corresponding to the first predefined format is a cyclic shift, and the cyclic shift values ​​corresponding to various SR transmission methods may be as shown in Table 1 above. And / or, the control signaling may indicate that the preset parameter corresponding to the second predefined format is a preset information block, and the preset information blocks corresponding to various SR transmission methods may be as shown in Table 2 above. It should be noted that in this embodiment, the execution order between steps 711 and steps 701, 702, and 703 is not limited. Figure 10 Only one scenario is shown where step 711 is performed before steps 701, 702, and 703.

[0091] In an implementation, the first SR can be an uplink SR, and the second SR can be a BFRQ. For example, when the SR resource of the terminal comes periodically and the SR needs to be transmitted through a PUCCH format 1b, the terminal can determine the value of the information block used for generating the SR sequence according to the current SR to be transmitted by using Table 2, when the terminal needs to transmit an UL_BFR and a BFR_SR, the terminal determines that the value of the information block used for generating the SR sequence is 10; when the terminal only needs to send an UL_BFR to the base station, the terminal determines that the value of the information block used for generating the SR sequence is 00; when the terminal only needs to send a BFR_SR to the base station, the terminal determines that the value of the information block used for generating the SR sequence is 11. When the terminal does not send an UL_BFR and a BFR_SR, the terminal does not take any operation. After the terminal performs QPSK modulation on the obtained information block, a symbol d is obtained, the terminal calculates an original sequence according to the time domain position of the SR resource used for transmitting the SR sequence, the initial cyclic shift corresponding to the PUCCH format 1b, and the orthogonal sequence pre-configured by the base station for the terminal, the terminal obtains the SR sequence by multiplying the symbol d with the original sequence, and transmits the SR sequence on the SR resource.
