Description

Technical Field

[0001] The present application relates to the field of communication technology, and in particular to an information transmission method and device. Background Art

[0002] The generation of data packets is not continuous. When there is no data transmission, the power consumption can be reduced by turning off the receiving circuit of the terminal device. Therefore, discontinuous reception (DRX) technology is introduced to save power. Terminal devices with energy-saving requirements will report energy-saving requests to the base station, and the base station configures the corresponding DRX cycle for the terminal device. At least one activation time period is defined in a DRX cycle, which can include several configurable different activation time periods including the DRX onduration. During the activation time period, the terminal device monitors and receives data from the downlink channel; in other time periods except the activation time period in the DRX cycle, the terminal device does not receive data from the downlink channel to save power consumption.

[0003] The current DRX mechanism itself defines the functional requirements of the receiving end, that is, it stipulates the receiving behavior of the terminal device receiving downlink signals. In the sidelink data transmission scenario, the original DRX mechanism is no longer suitable, because it cannot be simply assumed that the terminal device receiving downlink control information has DRX requirements. Summary of the invention

[0004] The embodiments of the present application provide an information transmission method and device, which can be applied to vehicle networking, such as V2X communication, long term evolution-vehicle (LTE-V), vehicle to vehicle (V2V) communication, etc., or can be used in the fields of intelligent driving, intelligent networked vehicles, etc., and can request side transmission resources for the first activation time period in the DRX cycle for the terminal device, thereby applying the DRX mechanism to the side transmission scenario and reducing the power consumption of the terminal device receiving the side data. In addition, the embodiments of the present application make full use of the existing technical solutions, and on the basis of ensuring the feasibility of the existing solutions, add new information expression methods to support the expression of resource request information.

[0005] In a first aspect, an embodiment of the present application provides an information transmission method, wherein the method may be executed by a terminal device, or may be executed by a component of the terminal device (such as a processor, a chip, or a chip system, etc.). The information transmission method may include: the terminal device determines control information, the control information includes resource request information, the resource request information is used to request allocation of sideline transmission resources in a first activation time period in a DRX cycle, and the DRX cycle includes at least one activation time period.

[0006] The first activation time period in the embodiment of the present application may be one or more activation time periods in at least one activation time period included in the DRX cycle. Optionally, the first activation time period may be a DRX On Duration in the DRX cycle.

[0007] Optionally, in addition to the resource request information, the control information may also include SR information and / or hybrid automatic repeat request (HARQ) information, which is not limited in the embodiments of the present application.

[0008] The terminal device sends control information to the network device. The terminal device may send the control information to the network device via a physical uplink control channel (PUCCH) or a physical uplink shared channel (PUSCH). If the control information is sent to the network device via PUCCH, the control information may be sent using one of PUCCH format 0, PUCCH format 1, PUCCH format 2, PUCCH format 3 and PUCCH format 4.

[0009] Correspondingly, the network device receives the control information and configures side transmission resources in the first activation time period for the terminal device according to the resource request information included in the control information.

[0010] By implementing the embodiments of the present application, the terminal device can request the network device to allocate sideline transmission resources in the first activation time period in the DRX cycle through resource request information, thereby applying the DRX mechanism in the sideline data transmission scenario and reducing the power consumption of the terminal device receiving the sideline data.

[0011] In one possible design, the terminal device receives resource scheduling information from the network device, where the resource scheduling information is used to indicate to the terminal device the side transmission resources in the first activation time period. The terminal device sends broadcast information or multicast information on the indicated side transmission resources.

[0012] Optionally, a terminal device with energy-saving requirements can be configured with a unified DRX cycle, and the terminal device with energy-saving requirements must receive information in the first activation time period of the DRX cycle. Therefore, when the terminal device sends broadcast information or multicast information on the side transmission resources of the first activation time period, other terminal devices can receive the broadcast information or multicast information, thereby improving the reliability of receiving the broadcast information or multicast information. The other terminal devices may include terminal devices with energy-saving requirements and terminal devices without energy-saving requirements.

[0013] By implementing this embodiment, the terminal device sends broadcast information or multicast information on the side transmission resources in the first activation time period configured by the network device, which can improve the reliability of the transmission of the broadcast information or multicast information.

[0014] In one possible design, the terminal device may send the control information to the network device using PUCCH format 0. Optionally, when the control information includes resource request information, the terminal device may send a first PUCCH format 0 sequence and a second PUCCH format 0 sequence, that is, the terminal device indicates the resource request information to the network device by sending two PUCCH format 0 sequences.

[0015] Among them, the first PUCCH format 0 sequence is obtained according to the first cyclic shift value, and the second PUCCH format 0 sequence is obtained according to the second cyclic shift value. Optionally, the first cyclic shift value and the second cyclic shift value may be values ​​in a preconfigured cyclic shift value set. The preconfigured cyclic shift value set may include at least two cyclic shift values. In some possible designs, the cyclic shift value set may only include the first cyclic shift value and the second cyclic shift value, which is not limited in the embodiments of the present application.

[0016] By implementing this embodiment, the terminal device can indicate to the network device that the control information includes resource request information by sending two PUCCH format 0 sequences, so that the network device can determine that the control information includes resource request information.

[0017] In one possible design, the control information includes HARQ information in addition to resource request information, that is, the network device expects the terminal device to send HARQ information, and the terminal device can determine the first cyclic shift value and the second cyclic shift value based on the HARQ information.

[0018] By implementing this embodiment, the first PUCCH format 0 sequence and the second PUCCH format 0 sequence sent by the terminal device can not only indicate the resource request information included in the control information to the network device, but also indicate the HARQ information included in the control information to the network device, thereby increasing the information type carried in the PUCCH format 0 sequence.

[0019] In one possible design, the first cyclic shift value corresponds to first HARQ information and first scheduling request SR information, the second cyclic shift value corresponds to the first HARQ information and the second scheduling request SR information, the first SR information indicates that the terminal device has a scheduling request, and the second SR information indicates that the terminal device does not have a scheduling request, and the first HARQ information can be the HARQ information that the terminal device prepares to feedback.

[0020] By implementing this embodiment, the first cyclic shift value and the second cyclic shift value are determined according to the HARQ information, the first SR information and the second SR information that the terminal device is ready to feedback, without adding a new cyclic shift value to represent the resource request information, and the compatibility is strong.

[0021] In a possible design, if the control information does not include HARQ information except resource request information, that is, the network device does not expect the terminal device to send HARQ information, then the first cyclic shift value may correspond to the first SR information, and the second cyclic shift value may correspond to the resource request information, and the first SR information indicates that the terminal device has a scheduling request. Optionally, the second cyclic shift value may be different from the first cyclic shift value.

[0022] Exemplarily, the second cyclic shift value may be a newly configured cyclic shift value corresponding to the resource request information. The second cyclic shift value may be an integer greater than or equal to 0 and less than or equal to 11, for example, the second cyclic shift value may be 3 or 6 or 9.

[0023] Optionally, the first PUCCH format 0 sequence obtained according to the first cyclic shift value can be used to indicate that the terminal device has a scheduling request. The second PUCCH format 0 sequence obtained according to the second cyclic shift value can be used to indicate that the terminal device requests to allocate sideline transmission resources in the first activation time period in the DRX cycle.

[0024] By implementing this embodiment, in a scenario where the control information does not include HARQ information, the terminal device can indicate the resource request information and SR information included in the control information to the network device by sending two PUCCH format 0 sequences.

[0025] Optionally, the second cyclic shift value may be configured by the network device.

[0026] In one possible design, if the control information includes resource request information but does not include HARQ information, that is, the network device does not expect the terminal device to send HARQ information, the terminal device can send a third PUCCH format 0 sequence, and the third PUCCH format 0 sequence can be obtained according to a third cyclic shift value, and the third cyclic shift value can correspond to the resource request information.

[0027] The third cyclic shift value may be a newly configured cyclic shift value corresponding to the resource request information. The third cyclic shift value may be different from the first cyclic shift value, and the first cyclic shift value may correspond to the first SR information, and the first SR information indicates that the terminal device has a scheduling request.

[0028] Exemplarily, the third cyclic shift value may be an integer greater than or equal to 0 and less than or equal to 11, for example, the third cyclic shift value may be 3 or 6 or 9.

[0029] Among them, the third PUCCH format 0 obtained according to the third cyclic shift value can be used to indicate that the terminal device requests allocation of sideline transmission resources in the first activation time period in the DRX cycle.

[0030] By implementing this embodiment, the third PUCCH format 0 sequence obtained by the newly configured third cyclic shift value indicates the resource request information included in the control information, that is, in a scenario where HARQ information is not included in the control information, the resource request information included in the control information can be indicated to the network device, and the number of PUCCH format 0 sequences sent can be reduced.

[0031] In one possible design, the terminal device may send the control information to the network device using PUCCH format 1. Optionally, if the control information includes resource request information but does not include HARQ information, that is, the network device does not expect the terminal device to send HARQ information, the terminal device may determine the bit information to be transmitted, that is, the control information, based on the resource request information, wherein the value of the bit information to be transmitted is 1.

[0032] It can be understood that if the control information only includes SR information for indicating that the terminal device has an SR request, but does not include resource request information and HARQ information, the terminal device can determine the bit information to be transmitted based on the SR information, wherein the value of the bit information to be transmitted is 0.

[0033] By implementing this embodiment, the difference in the value of the bit information to be transmitted is used to indicate to the network device that the control information includes the resource request information, without adding new bits, and thus the overhead is small.

[0034] Further optionally, the terminal device may adopt binary phase shift keying (BPSK) to modulate the bit information to be transmitted, and use PUCCH format 1 to send the modulated bit information to the network device.

[0035] By implementing this embodiment, the bit information to be transmitted can still be modulated using BPSK, thereby not changing the existing modulation method and having strong compatibility.

[0036] In one possible design, the terminal device may determine the bit information to be transmitted, ie, the control information, based on the HARQ information, the SR information and the resource request information.

[0037] Optionally, the HARQ information may be 1 bit or 2 bits.

[0038] Exemplarily, the network device expects the terminal device to send 1 bit of HARQ information, and the terminal device also has a demand for sideline transmission resources in the first activation time period of the DRX cycle. The terminal device determines the bit information to be transmitted based on the 1 bit of HARQ information, SR information and resource request information.

[0039] Exemplarily, the network device expects the terminal device to send 2 bits of HARQ information, and the terminal device also has a demand for sideline transmission resources in the first activation time period of the DRX cycle. The terminal device determines the bit information to be transmitted based on the 2 bits of HARQ information, SR information and resource request information.

[0040] By implementing this embodiment, resource request information can be carried in the bit information to be transmitted, so that the network device can allocate side transmission resources in the first activation time period in the DRX cycle to the terminal device.

[0041] In one possible design, when the bit information to be transmitted includes 1-bit HARQ information, SR information and resource request information, the terminal device can use π / 4 quadrature phase shift keying (quadrature phase shift keyin, QPSK) to modulate the 1-bit HARQ information and SR information in the bit information to be transmitted, and use PUCCH format 1 in the SR reporting time slot to send the modulated bit information to the network device.

[0042] It can be understood that if the bit information to be transmitted does not include resource request information, but only includes 1-bit HARQ information and SR information, the terminal device can use QPSK to modulate the 1-bit HARQ information and SR information.

[0043] By implementing this embodiment, the terminal device indicates resource request information to the network device through different modulation methods, thereby increasing the number of bit information that can be carried by the PUCCH format 1 signal.

[0044] In one possible design, when the bit information to be transmitted includes 2-bit HARQ information, SR information and resource request information, the terminal device can use 16QAM to modulate the bit information to be transmitted, and use PUCCH format 1 in the SR reporting time slot to send the modulated bit information to the network device.

[0045] By implementing this embodiment, the terminal device can adopt a higher-order modulation method to modulate the bit information to be transmitted, thereby increasing the number of bits that can be carried by the PUCCH format 1 signal.

[0046] In one possible design, the terminal device may encode the control information and send the encoded control information to the network device using one of PUCCH formats 2, PUCCH format 3, or PUCCH format 4. Optionally, after encoding the control information, the terminal device may also perform other operations such as scrambling and modulation on the encoded control information, which is not limited in the embodiments of the present application.

[0047] Optionally, the control information may be UCI, and 1 bit of information may be added to the UCI to indicate resource request information.

[0048] By implementing this embodiment, the terminal device may use one of PUCCH formats 2, 3 or 4 to indicate resource request information to the network device.

[0049] In a second aspect, an embodiment of the present application provides an information transmission method, wherein the method may be executed by a network device, or may be executed by a component of the network device (such as a processor, a chip, or a chip system, etc.). The information transmission method may include: the network device receives control information, the control information includes resource request information, the resource request information is used to request a sideline transmission resource to be allocated in a first activation time period in a DRX cycle, and the DRX cycle includes at least one activation time period.

[0050] Further, the network device may configure the side transmission resources in the first activation time period for the terminal device according to the resource request information. Optionally, the network device may indicate the configured side transmission resources to the terminal device through resource scheduling information, so that the terminal device sends broadcast information or multicast information on the indicated side transmission resources.

[0051] By implementing the embodiments of the present application, the network device can allocate sideline transmission resources in the first activation time period in the DRX cycle to the terminal device based on the resource request information, thereby applying the DRX mechanism to the sideline data transmission scenario and reducing the power consumption of the terminal device receiving the sideline data.

[0052] It can be understood that the terminal device can send the control information to the network device through PUCCH or PUSCH, and correspondingly, the network device receives the control information through PUCCH or PUSCH. If the control information is sent to the network device through PUCCH, the network device can schedule the terminal device to use one of PUCCH format 0, PUCCH format 1, PUCCH format 2, PUCCH format 3 and PUCCH format 4 to send the control information to the network device, and correspondingly, the network device receives the signal of the corresponding PUCCH format and determines the information contained in the control information based on the received signal of the PUCCH format.

[0053] In one possible design, the network device schedules the terminal device to send control information using PUCCH format 0. If the terminal device sends the first PUCCH format 0 sequence and the second PUCCH format 0 sequence, that is, the terminal device indicates resource request information to the network device by sending two PUCCH format 0 sequences. Accordingly, the network device receives the first PUCCH format 0 sequence and the second PUCCH format 0 sequence, and can determine that the control information includes resource request information, that is, it is determined that the terminal device has a demand for uplink transmission resources in the first activation time period in the DRX cycle.

[0054] The first PUCCH format 0 sequence is obtained according to a first cyclic shift value, and the second PUCCH format 0 sequence is obtained according to a second cyclic shift value, and the first cyclic shift value and the second cyclic shift value are values ​​in a preconfigured cyclic shift value set.

[0055] By implementing this embodiment, the network device can determine the resource request information included in the control information through the two PUCCH format 0 sequences sent by the terminal device.

[0056] In one possible design, if the network device also expects the terminal device to send HARQ information, that is, the control information includes HARQ information in addition to the resource request information, the first cyclic shift value and the second cyclic shift value can be determined based on the HARQ information included in the control information.

[0057] The network device may obtain a first cyclic shift value corresponding to a first PUCCH format 0 sequence and a second cyclic shift value corresponding to a second PUCCH format 0 sequence, and determine the HARQ information included in the control information according to the first cyclic shift value and / or the second cyclic shift value.

[0058] By implementing this embodiment, the first PUCCH format 0 sequence and the second PUCCH format 0 sequence can indicate not only resource request information, but also HARQ information, thereby increasing the type of information indicated.

[0059] In a possible design, the first cyclic shift value may correspond to the first HARQ information and the first scheduling request SR information, the second cyclic shift value may correspond to the first HARQ information and the second scheduling request SR information, the first SR information indicates that the terminal device has a scheduling request, and the second SR information indicates that the terminal device does not have a scheduling request. The first HARQ information is the HARQ information fed back by the terminal device to the network device.

[0060] By implementing this embodiment, it is possible to increase the resource request information while indicating the first HARQ information on the basis of the existing cyclic shift value set, thereby achieving strong compatibility.

[0061] In one possible design, if the network device does not expect the terminal device to send HARQ information, that is, the control information does not include HARQ information except SR information and resource request information, the network device can determine that the terminal device has an SR request and that the terminal device requests the allocation of sideline transmission resources in the first activation time period in the DRX cycle based on the received first PUCCH format 0 sequence and the second PUCCH format 0 sequence.

[0062] Optionally, the first cyclic shift value may correspond to first SR information, and the second cyclic shift value may correspond to resource request information, and the first SR information indicates that a scheduling request exists for the terminal device.

[0063] The network device can also further obtain a first cyclic shift value corresponding to the first PUCCH format 0 sequence and a second cyclic shift value corresponding to the second PUCCH format 0 sequence. If the first cyclic shift value corresponds to the first SR information and the second cyclic shift value corresponds to the resource request information, it is determined that the terminal device has an SR request and that the terminal device has a demand for uplink transmission resources in the first activation time period of the DRX cycle.

[0064] By implementing this embodiment, when the network device does not expect the terminal device to send HARQ information, it can determine the resource request information and the first SR information included in the control information through the received first PUCCH format 0 sequence and second PUCCH format 0 sequence.

[0065] In one possible design, the second cyclic shift value corresponding to the resource request information may be configured by the network device for the terminal device, and the network device may indicate the second cyclic shift value to the terminal device.

[0066] In one possible design, if the network device does not expect the terminal device to send HARQ information, that is, the control information does not include HARQ information, the network device receives a third PUCCH format 0 sequence, and further obtains a third cyclic shift value corresponding to the third PUCCH format 0 sequence. If the third cyclic shift value is the cyclic shift value corresponding to the resource request information, it can be determined that the control information includes resource request information, that is, it is determined that the terminal device has a demand for upper side transmission resources in the first activation time period in the DRX cycle.

[0067] Optionally, the third cyclic shift value is an integer greater than or equal to 0 and less than or equal to 11.

[0068] By implementing this embodiment, the third PUCCH format 0 sequence obtained by the newly configured third cyclic shift value indicates the resource request information included in the control information, that is, in a scenario where HARQ information is not included in the control information, the resource request information included in the control information can be indicated to the network device, and the number of PUCCH format 0 sequences sent can be reduced.

[0069] In one possible design, the network device schedules the terminal device to use PUCCH format 1 to send control information (i.e., bit information). If the network device does not expect the terminal device to send HARQ information, that is, the bit information does not include HARQ information, the network device determines that the terminal device uses BPSK to modulate the bit information. Accordingly, after the network device receives the PUCCH format 1 signal, it decodes the PUCCH format 1 signal based on BPSK to obtain the bit information.

[0070] If the value of the bit information is 1, it is determined that the control information includes resource request information, that is, it is determined that the terminal device has a demand for uplink transmission resources in the first activation time period of the DRX cycle.

[0071] By implementing this embodiment, the resource request information included in the control information can be additionally indicated without increasing the number of bits and changing the modulation mode.

[0072] In one possible design, if the network device expects the terminal device to send 1 bit of HARQ information, that is, the bit information includes 1 bit of HARQ information, in order to further determine whether the bit information includes resource request information, the network device can further detect the modulation method of the PUCCH format 1 signal after receiving the PUCCH format 1 signal.

[0073] If the signal of the PUCCH format 1 is modulated based on π / 4QPSK, the bit information includes resource request information. Further, the network device decodes the signal of the PUCCH format 1 based on π / 4QPSK, thereby further obtaining 1 bit of HARQ information and SR information in addition to the resource request information contained in the bit information.

[0074] By implementing this embodiment, the terminal device indicates resource request information to the network device through different modulation methods, thereby increasing the number of bit information that can be carried by the PUCCH format 1 signal.

[0075] In a possible design, if the network device expects the terminal device to send 2 bits of HARQ information, that is, the bit information includes 2 bits of HARQ information, the network device can determine that the terminal device modulates the bit information using 16QAM, and accordingly, after receiving the PUCCH format 1 signal, the network device decodes the PUCCH format 1 signal based on 16QAM to obtain the bit information. The bit information includes resource request information, SR information and 2 bits of HARQ information.

[0076] By implementing this embodiment, the terminal device can adopt a higher-order modulation method to modulate the bit information to be transmitted, thereby increasing the number of bits that can be carried by the PUCCH format 1 signal.

[0105] First, before describing the embodiments of the present application, the names or terms involved in the embodiments of the present application are introduced.

[0106] 1. There are two main transmission modes in the sideline data transmission scenario: the mode based on base station scheduling is transmission mode 1, and the mode in which the user equipment (UE) independently selects sideline transmission resources is transmission mode 2. The following introduces transmission mode 1 and transmission mode 2 respectively:

[0107] Transmission mode 1 can be used for V2X communication within the coverage area of ​​the base station. Taking dynamic scheduling as an example, the base station centrally allocates resources based on the buffer status report (BSR) of the UE. Specifically, Figure 1 As shown, the base station indicates the time-frequency resources of the sidelink data of the transmitting UE through downlink control information (DCI). The transmitting UE receives the DCI and sends the sidelink control information (SCI) and data to the receiving UE on the time-frequency resources indicated by the DCI. In transmission mode 1, the sidelink transmission resources of each UE are uniformly scheduled by the base station, so collision can be avoided.

[0108] Transmission mode 2 may refer to the UE selecting the time-frequency resources used for communication from the available time-frequency resources contained in the communication resource pool, and sending control messages and data on the selected time-frequency resources. In transmission mode 2, the UE's side transmission resources may be selected by the UE based on the results of its own monitoring. This mode may not be limited by network coverage. In the absence of network coverage, the transmitting UE may also use this mode for communication.

[0109] 2. Scheduling request (SR) information and BSR information feedback

[0110] The UE can send SR information to the base station to inform the scheduler of the base station whether the UE has a scheduling request. In the subsequent embodiments of the present application, for the convenience of description, the existence of a scheduling request for the UE is referred to as the UE having an SR request, and the absence of a scheduling request for the UE is referred to as the UE having no SR request. For UEs with scheduling requests, BSR information must also be reported to inform the base station of the size and priority of the service data to be sent by the UE. Among them, SR information and BSR information can be carried in the uplink control channel (physical uplink control channel, PUCCH) and the physical uplink shared channel (physical uplink shared channel, PUSCH).

[0111] 3. Hybrid automatic repeat request (HARQ) information

[0112] The HARQ protocol exists at both the transmitting and receiving ends. The HARQ operation at the transmitting end includes transmitting and retransmitting transport blocks (TB), receiving and processing acknowledgment (ACK) information and / or negative acknowledgement (NACK) information. The HARQ operation at the receiving end includes receiving TB, soft combining processing, generating and feeding back ACK / NACK information. Among them, after each TB is sent by the transmitting end, the receiving end receives the TB and performs a cyclical redundancy check (CRC) on it. If the CRC check succeeds, ACK information is fed back to the transmitting end. If the CRC check fails, NACK information is fed back. If the transmitting end receives the ACK information, it transmits a new TB. If the transmitting end receives the NACK information, it retransmits the corresponding TB.

[0113] In this application, ACK and / or NACK information is referred to as HARQ information.

[0114] 4. PUCCH format

[0115] PUCCH is used to transmit uplink control information (UCI). UCI may include one or more of HARQ information, SR information, link recovery request (LRR) and channel state information (CSI). NR PUCCH has five formats. The occupied time domain and frequency domain resources and the number of information bits that can be carried are shown in Table 1:

[0116] Table 1 PUCCH format

[0117]

[0118]

[0119] PUCCH format 0 and PUCCH format 1 use different sequences to feed back different information, and PUCCH formats 2 to 4 use the encoding method of UCI to feed back.

[0120] 5. PUCCH format 0

[0121] PUCCH format 0 is based on a low peak-to-average ratio ZC sequence. The specific generation method is to generate a basic sequence r(n) according to the sequence length, 0≤n<M ZC , a phase rotation is performed based on the basic sequence r(n) to generate a reusable low peak-to-average ratio sequence. For example, a reusable low peak-to-average ratio sequence can be generated according to the following formula:

[0122] r α (n) = r*e jαn , 0≤n<M ZC

[0123] For example, in the NR standard, the PUCCH format 0 sequence length is 12, that is, M ZC =12, and PUCCH format 0 supports multiple users to be sent on one RB based on the sequence generated in the above manner. Since the UE needs to feedback ACK information and NACK information, a user is assigned at least two sequences, corresponding to different α values. The phase rotation value α can be determined by the following formula:

[0124]

[0125] Indicates the number of subcarriers in an RB. NR defines this value as 12. Indicates the time slot number corresponding to the current subcarrier spacing μ in a wireless frame. For PUCCH format 0, l∈{0,1}, l represents the symbol index of the sequence in the current PUCCH feedback resource. l′ represents the symbol index of the first symbol of the current PUCCH channel in the current time slot. m 0 It is configured by the network for each UE and indicates the initial phase of the current user. The base station needs to configure different sequence cyclic shift values ​​for each user. cs , to express the ACK information or NACK information in the HARQ information, as well as information such as whether there is an SR request, among which the sequence cyclic shift value m csIt can also be called a cyclic shift value, and they can be replaced with each other. For the convenience of description, in the subsequent embodiments, they are referred to as cyclic shift values.

[0126] m cs The configuration scheme can be shown in Table 2-Table 5 below, where the HARQ information in Table 2 and Table 3 is 1 bit, and Table 2 is used to indicate the m corresponding to different HARQ information when the UE has no SR request. cs Table 3 is used to indicate the m corresponding to different HARQ information when the UE has an SR request. cs .

[0127] The HARQ information in Table 4 and Table 5 is 2 bits. Table 4 is used to indicate the m corresponding to different HARQ information when the UE has no SR request. cs Table 5 is used to indicate the m corresponding to different HARQ information when the UE has an SR request. cs .

[0128] Among them, a HARQ-ACK Value of 0 can be used to indicate that the HARQ information is NACK information, and a HARQ-ACK Value of 1 can be used to indicate that the HARQ information is ACK information.

[0129] HARQ-ACK Value 0 1 Sequence cyclic shift <![CDATA[m CS =0]]> <![CDATA[m CS =6]]>

[0130] HARQ-ACK Value 0 1 Sequence cyclic shift <![CDATA[m CS =3]]> <![CDATA[m CS =9]]>

[0131] HARQ-ACK Value {0，0} {0，1} {1，1} {1，0} Sequence cyclic shift <![CDATA[m CS =0]]> <![CDATA[m CS =3]]> <![CDATA[m CS =6]]> <![CDATA[m CS =9]]>

[0132] HARQ-ACK Value {0，0} {0，1} {1，1} {1，0} Sequence cyclic shift <![CDATA[m CS =1]]> <![CDATA[m CS =4]]> <![CDATA[m CS =7]]> <![CDATA[m CS =10]]>

[0133] According to the above configuration parameters, a phase cyclic shift parameter α can be uniquely determined, and the PUCCH format 0 sequence is determined by the α. The specific calculation process can be referred to Figure 2 As shown, an m can be determined based on the HARQ information and / or the SR information. cs , and according to the high-level configuration m 0 The phase rotation factor is calculated using the parameters such as PUCCH format 0, thereby generating the transmission data according to the generated base sequence.

[0134] Optionally, HARQ information and SR information can be transmitted using PUCCH format 0 alone. For example, in a time slot other than SR reporting, if the UE needs to feedback HARQ information, PUCCH format 0 can be used alone to transmit HARQ information. In this scenario, the base station will configure Table 2 or Table 4 for the UE. If Table 2 is configured, it means that the base station expects the UE to feedback 1 bit of HARQ information. If Table 4 is configured, it means that the base station expects the UE to feedback 2 bits of HARQ information.

[0135] For example, in the time slot reported by SR, the UE does not receive the scheduling information of the data, so it does not need to feedback the HARQ information, that is, the base station does not expect the UE to feedback the HARQ information, and can use PUCCH format 0 to transmit the SR information alone. In this scenario, the base station can configure a sequence for the UE, that is, m cs =0 indicates the sequence. If the UE does not have an SR request, it may not report the SR information, that is, it does not send any PUCCH format 0 signal. If the UE has an SR request, it may send the m cs =0 represents the PUCCH format 0 sequence.

[0136] Optionally, HARQ information and SR information can also be bundled together and transmitted using PUCCH format 0. For example, in the time slot where SR is reported, the UE needs to feedback HARQ information. If the base station expects the UE to feedback 1 bit of HARQ information, the base station will configure Table 2 and Table 3 for the UE. If the UE has no SR request, the UE selects Table 2 to feedback HARQ information. If the UE has an SR request, the UE selects Table 3 to feedback HARQ information.

[0137] If the base station expects the UE to feedback 2 bits of HARQ information, the base station will configure Table 4 and Table 5 for the UE. If the UE has no SR request, the UE selects Table 4 to feedback HARQ information. If the UE has an SR request, the UE selects Table 5 to feedback HARQ information.

[0138] In the above scenario, the UE determines an m based on the HARQ information and / or SR information. cs , and according to the m cs Generate a corresponding PUCCH format 0 sequence and send it to the base station.

[0139] 6. PUCCH format 1

[0140] PUCCH format 1 still supports multiple users on the same time-frequency resource, and the transmitted signal is further coded and modulated based on the low peak-to-average ratio ZC sequence. The number of users supported for multiplexing on the same time-frequency resource is determined by the number of continuous symbols in the PUCCH time domain excluding the pilot. Unlike PUCCH format 0, the ZC sequence of PUCCH format 1 does not carry any information. The ZC sequences of multiple users multiplexed on the same time-frequency resource are α (n) is exactly the same, the specific process is as follows Figure 3 shown.

[0141] like Figure 3 As shown, the base station configures m for users multiplexed on the same time-frequency resources. 0 The same, thus generating the same ZC sequence rα (n), n represents the subcarrier index. After the bit information b(0) to be transmitted by each user is modulated, the modulation symbol d(0) is output, and the modulation mode includes BPSK or QPSK. Among them, b(0) can be 1 bit or 2 bits. If b(0) is 1 bit, the modulation mode is BPSK, and if b(0) is 2 bits, the modulation mode is QPSK.

[0142] Further modulate d(0) onto the generated ZC sequence, that is, α (n) to generate y(n) = d(0)*r α (n).

[0143] Generate an orthogonal expansion factor w on symbol m according to user i i (m), And put w i (m) is multiplied by each y(n) to generate the output sequence z(m,n)=y(n)*w on each symbol i (m).

[0144] Optionally, HARQ information and SR information can be transmitted using PUCCH format 1 alone. For example, in a time slot other than SR reporting, if the UE needs to feedback HARQ information, PUCCH format 1 can be used alone to transmit the HARQ information. In this scenario, if the base station expects the HARQ information fed back by the UE to be 1 bit, that is, the bit information b(0) to be transmitted is 1 bit, BPSK is used to modulate the bit information b(0) to be transmitted. If the base station expects the HARQ information fed back by the UE to be 2 bits, that is, the bit information b(0) to be transmitted is 2 bits, QPSK is used to modulate the bit information b(0) to be transmitted.

[0145] For another example, in the time slot where SR is reported, the UE does not receive data, so there is no need to feedback HARQ information, that is, the base station does not expect the UE to feedback HARQ information, and the SR information can be transmitted using PUCCH format 1 alone. In this scenario, if the UE does not have an SR request, the SR information may not be reported, that is, no PUCCH format 1 signal is sent. If the UE has an SR request, the bit information to be transmitted b(0) = 0, and the bit information to be transmitted b(0) is modulated using BPCK.

[0146] Optionally, HARQ information and SR information can also be bundled together and transmitted using PUCCH format 1. For example, in the time slot in which the SR is reported, the UE needs to feedback HARQ information. If the base station expects the UE to feedback 1 bit of HARQ information, both the SR information and the 1 bit of HARQ information can be transmitted using PUCCH format 1. The bit information b(0) to be transmitted is 2 bits, and the bit information b(0) to be transmitted is modulated using QPSK. If the base station expects the UE to feedback 2 bits of HARQ information, the UE will discard the SR information and use PUCCH format 1 to transmit 2 bits of HARQ information. The bit information b(0) to be transmitted is 2 bits, and the bit information b(0) to be transmitted is modulated using QPSK.

[0147] 7. PUCCH format 2 / 3 / 4

[0148] PUCCH format 2 / 3 / 4 can carry one or more information including HARQ information, SR information, link recovery request (LRR) and channel state information (CSI). The control information to be sent (which can be called the bit information to be transmitted) can be transmitted through Figure 4 The encoding method shown is used for transmission. Figure 4 As shown, the bit information to be transmitted is sent through operations such as channel coding, scrambling, and modulation. Among them, PUCCH format 2 and PUCCH format 4 support the transformation precoding shown in the dotted box, while PUCCH format 3 may not perform the transformation precoding step. After receiving the PUCCH reporting information, the base station side obtains the corresponding control information through decoding and parsing.

[0149] 8. DRX

[0150] The generation of data packets is not continuous. When there is no data transmission, the power consumption can be reduced by turning off the UE's receiving circuit, thereby increasing the service life of the mobile battery. Therefore, DRX technology is introduced for power saving. The UE can be configured with several consecutive DRX cycles. A DRX cycle defines the active time, which can include a set of several configurable different activation time periods including the DRX On Duration. In the NR system, the DRX On Duration can be indicated by the parameter drx-onDurationTimer. The several configurable different activation time periods contained in a DRX cycle can be continuous or discontinuous in time. During the active time period of a DRX cycle, the UE monitors and receives the PDCCH; at other times in the DRX cycle except the active time period, the UE does not receive data on the downlink channel to save power consumption.

[0151] The resource request information in the embodiment of the present application is used to request the allocation of sideline transmission resources in the first activation time period in the DRX cycle, and the first activation time period may be a DRX on time period (DRX On Duration) in the DRX cycle. It can be understood that it may also be other activation time periods, which are not limited in the embodiment of the present application. The first activation time period may include one or more activation time periods.

[0152] Optionally, the resource request information may also be referred to as a DRX resource request, or a DRX on time slot resource request, etc., which is not limited in the embodiments of the present application.

[0153] In an embodiment of the present application, the network device expects the terminal device to send HARQ information, which can also be referred to as the network device having HARQ information feedback expectations. For example, the network device sends data to the terminal device, and correspondingly, the terminal device has demodulation information of the received data. Therefore, the terminal device needs to send HARQ information to the network device.

[0154] The network device not expecting the terminal device to send HARQ information can also be called the network device having no HARQ information feedback expectation. For example, the network device does not send data to the terminal device, and accordingly, the terminal device does not receive the demodulation information of the data. Therefore, the terminal device will not send HARQ information to the network device.

[0155] The present application can be applied in transmission mode 1 of the sidelink data transmission scenario. If the receiving UE (also referred to as the receiving terminal device, or the receiving user, etc.) on the sidelink link has energy saving requirements, the DRX mechanism is introduced, that is, the DRX cycle is configured for the receiving UE. Before sending data to the receiving UE, the transmitting UE (also referred to as the sending terminal device, or the sending user, etc.) on the sidelink link requests the base station for the sidelink transmission resources corresponding to the activation time period in the DRX cycle of the receiving UE, so that the receiving UE can receive the data sent by the sending UE.

[0156] In the broadcast service scenario, the transmitting UE does not know which receiving UEs there are before sending data. Therefore, when the transmitting UE requests sidelink transmission resources from the base station, it cannot determine the DRX cycle of the receiving UE, and cannot guarantee the reliability of receiving all broadcast service data.

[0157] To support the DRX mechanism of broadcast service scenarios, a unified DRX cycle can be configured for all UEs with energy saving requirements, such as defining that all UEs with energy saving requirements must receive information within the first activation time period of the DRX cycle. The first activation time period may be a DRX on time period (DRX On Duration). The present application provides a variety of methods to facilitate the originating UE to request the base station to allocate side transmission resources within the first activation time period in the DRX cycle, so as to ensure the reliability of broadcast service data reception. For details, please refer to the description of the subsequent embodiments.

[0158] It is understandable that the present application may also be applicable to multicast service scenarios, and the embodiments of the present application are not limited thereto.

[0159] The technical solutions of the embodiments of the present application can be applied to vehicle networks, such as V2X communication, long-term evolution-yehicle (LTE-V) communication technology, vehicle-to-vehicle (V2V) communication, etc., or can be used in the fields of intelligent driving, intelligent connected vehicles, etc., and can also be used in other wireless networks, such as WiFi networks, long-term evolution (LTE) networks, fifth-generation (5G) networks, new radio (NR) networks, device-to-device (D2D) networks, future networks, etc., as well as other new networks that emerge with the development of technology.

[0160] Figure 5A schematic diagram of a network system that can be applied to the present application is shown, and the network system may include a network device and one or more terminal devices. The one or more terminal devices may all be within the coverage of the network device, or some of the terminal devices may be within the coverage of the network device. It is understandable that the terminal device that sends control information to the network device in the embodiment of the present application is within the coverage of the network device.

[0161] A network device is a device that connects a terminal device to a wireless network, and specifically can be a base station, a transceiver node (Tx / Rx Point), a road side unit (Road Side Unit), etc. The base station can include various forms of base stations, such as: macro base stations, micro base stations (also called small stations), relay stations, access points, etc. Specifically, it can be: an access point (AP) in a wireless local area network (WLAN), a base transceiver station (BTS) in a global system for mobile communications (GSM) or code division multiple access (CDMA), or a base station (NodeB, NB) in a wideband code division multiple access (WCDMA), or an evolved Node B (eNB or eNodeB) in LTE, or a relay station or access point, and the next generation Node B (gNB) in a 5G system or a base station in a future evolved public land mobile network (PLMN) network, etc.

[0162] Terminal equipment may also be referred to as user equipment UE, access terminal, terminal, user unit, user station, mobile station, mobile station, remote station, remote terminal, mobile device, user terminal, wireless network equipment, vehicle-mounted terminal, user agent, user device, access point, and other vehicles with V2V communication capabilities, etc. The terminal may be a cellular phone, a cordless phone, a session initiation protocol (SIP) phone, a wireless local loop (WLL) station, a personal digital assistant (PDA), a handheld device with wireless communication capabilities, a computing device or other device connected to a wireless modem, a vehicle-mounted device, a wearable device or the Internet of Things, a terminal device in a vehicle network, and any form of terminal device in a future network, etc. The terminal device may communicate with one or more core networks (CN) via a network device. It is understandable that in some possible application scenarios, the terminal device of the embodiment of the present application may also be a virtual reality (VR) terminal device with wireless transceiver function, an augmented reality (AR) terminal device, a wireless terminal device in industrial control, a wireless terminal device in self-driving, a wireless terminal device in remote medical, a wireless terminal device in smart grid, a wireless terminal in transportation safety, a wireless terminal device in smart city, and a wireless terminal in smart home. The terminal device can be deployed on land, including indoors or outdoors, handheld or vehicle-mounted; it can also be deployed on the water (such as a ship, etc.); it can also be deployed in the air (such as an airplane, a balloon, and a satellite, etc.).

[0163] It should be understood that the embodiments of the present application are not limited to application only in Figure 1 For example, a communication system to which the information transmission method according to the embodiment of the present application can be applied may include more or fewer network elements or devices.

[0164] In one possible scenario, if the embodiment of the present application is applied in a V2V communication scenario, V2V communication can be regarded as a special case of device-to-device (D2D) communication. Through communication between vehicles, status information of other vehicles and road conditions can be obtained in real time, thereby better assisting vehicle driving and even realizing autonomous driving.

[0165] In the explanation of subsequent embodiments, when a network device receives resource request information from a terminal device, in addition to determining that the terminal device requests to be allocated side transmission resources in the first activation time period in the DRX cycle, it can also be considered that the terminal device has a resource scheduling request. Therefore, in the embodiment of the present application, the resource request information, when expressing the side transmission resource request in the first activation time period, may also additionally express SR information for indicating that the terminal device has a SR request.

[0166] In addition, the resource request information mentioned in the embodiments of the present application is used to request allocation of sidelink transmission resources in the first activation time period in the DRX cycle.

[0167] Please refer to Figure 6 , is a flow chart of an information transmission method provided in an embodiment of the present application. As shown in the figure, the information transmission method in the embodiment of the present application includes but is not limited to the following steps:

[0168] S101, a terminal device determines control information, wherein the control information includes resource request information, wherein the resource request information is used to request allocation of sidelink transmission resources in a first activation time period in a discontinuous reception DRX cycle, wherein the DRX cycle includes at least one activation time period.

[0169] In one embodiment, the control information may be UCI, and the control information includes resource request information. Optionally, in addition to the resource request information, the control information may also include SR information and / or HARQ information. The DRX cycle may include at least one activation time period, and the first activation time period in the embodiment of the present application may be one or more activation time periods in the at least one activation time period. Optionally, the first activation time period may be a DRX on time period (DRX On Duration) in the DRX cycle.

[0170] S102, the terminal device sends the control information to the network device.

[0171] In one embodiment, the terminal device may send the control information to the network device via PUCCH or PUSCH. Wherein, if the control information is sent to the network device via PUCCH, the control information may be sent using one of PUCCH formats 0, PUCCH format 1, PUCCH format 2, PUCCH format 3 and PUCCH format 4. The following describes the use of the above PUCCH formats to send the control information. Optionally, the control information of the embodiment of the present application may be sent in the time slot reported by SR, wherein the time slot reported by SR may be understood as that the SR information may be sent periodically, that is, the time slot reported by SR information may be defined. Of course, the terminal device may send SR information through control information in the time slot reported by SR, or may not send SR information. For example, if the terminal device does not need to send other information in the time slot reported by SR (other information may be HARQ information, which may refer to the description of subsequent embodiments), if the terminal device does not have a scheduling request, the SR information may not be sent. Optionally, if the terminal device needs to send other information within the time slot reported by the SR, the SR information and other information can be sent together within the time slot reported by the SR. The SR information is used to indicate whether the terminal device has a scheduling request.

[0172] 1. Use PUCCH format 0 to send control information

[0173] The network device schedules the terminal device to send control information using PUCCH format 0. Since PUCCH format 0 uses different sequences to represent different information in the control information, and different sequences are configured by different cyclic shift values ​​m cs For details, please refer to the different cyclic shift values ​​m in Table 2-Table 5 in the above embodiments. cs The corresponding different information.

[0174] In an optional implementation, in the time slot reported by the SR, when the resource request information is included in the control information, the first PUCCH format 0 sequence and the second PUCCH format 0 sequence may be sent, that is, the terminal device indicates the resource request information to the network device by sending two PUCCH format 0 sequences. The first PUCCH format 0 sequence is obtained according to the first cyclic shift value, and the second PUCCH format 0 sequence is obtained according to the second cyclic shift value. Optionally, the first cyclic shift value and the second cyclic shift value may be values ​​in a preconfigured cyclic shift value set. The preconfigured cyclic shift value set may include at least two cyclic shift values. In some possible designs, the cyclic shift value set may include only the first cyclic shift value and the second cyclic shift value.

[0175] Optionally, in the time slot reported by SR, if the control information includes HARQ information in addition to resource request information, that is, the network device expects the terminal device to send HARQ information, then the terminal device can determine the first cyclic shift value and the second cyclic shift value based on the HARQ information. Exemplarily, the first cyclic shift value corresponds to the first HARQ information and the first scheduling request SR information, the second cyclic shift value corresponds to the first HARQ information and the second scheduling request SR information, the first SR information indicates that the terminal device has a scheduling request, and the second SR information indicates that the terminal device does not have a scheduling request. The first HARQ information can be the HARQ information that the terminal device is ready to feedback.

[0176] Exemplarily, in the time slot reported by the SR, if the HARQ information is 1 bit, that is, the network device expects the terminal device to send 1 bit of HARQ information, then the network device can configure Table 2 and Table 3 in the above embodiment for the terminal device. The cyclic shift values ​​included in Table 2 and Table 3 can constitute a preconfigured cyclic shift value set. The terminal device determines two cyclic shift values ​​m from Table 2 and Table 3 respectively according to the 1-bit first HARQ information to be fed back. cs , respectively as the first cyclic shift value and the second cyclic shift value, and generate the first PUCCH format 0 sequence according to the first cyclic shift value, and generate the second PUCCH format 0 sequence according to the second cyclic shift value. The terminal device sends the generated first PUCCH format 0 sequence and the second PUCCH format 0 sequence to the network device at the same time in the time slot reported by the SR. For example, if the 1-bit first HARQ information is ACK information, that is, the HARQ-ACK Value is 1, then the two cyclic shift values ​​m cs can be 6 and 9 respectively; if the 1-bit first HARQ information is NACK information, that is, the HARQ-ACK Value is 0, then the two cyclic shift values ​​m cs Can be 0 and 3 respectively.

[0177] For example, in the time slot reported by the SR, if the HARQ information is 2 bits, that is, the network device expects the terminal device to send 2 bits of HARQ information, then the network device can configure Table 4 and Table 5 for the terminal device. The cyclic shift values ​​included in Table 4 and Table 5 can constitute a preconfigured cyclic shift value set. The terminal device determines two cyclic shift values ​​m from Table 4 and Table 5 respectively according to the 2-bit first HARQ information to be fed back. cs, respectively as the first cyclic shift value and the second cyclic shift value, and generate the first PUCCH format 0 sequence according to the first cyclic shift value, and generate the second PUCCH format 0 sequence according to the second cyclic shift value. The terminal device sends the generated first PUCCH format 0 sequence and the second PUCCH format 0 sequence to the network device at the same time in the time slot reported by the SR. For example, if the 2-bit first HARQ information is NACK information and NACK information, that is, the HARQ-ACK Value is 00, then the two cyclic shift values ​​m cs can be 0 and 1 respectively; if the 2-bit first HARQ information is NACK information and ACK information, that is, the HARQ-ACK Value is 01, then the two cyclic shift values ​​m cs It can be 3 and 4 respectively, and the others can be deduced by analogy. Among them, the first HARQ information is NACK information and NACK information, which can indicate that the HARQ information corresponding to the two transport blocks is NACK information. The first HARQ information is NACK information and ACK information, which can indicate that the HARQ information corresponding to the first transport block is NACK information, and the HARQ information corresponding to the second transport block is ACK information, and the others can be deduced by analogy.

[0178] Correspondingly, the network device can determine the resource request information, SR information and first HARQ information included in the control information according to the first cyclic shift value corresponding to the first PUCCH format 0 sequence and / or the second cyclic shift value corresponding to the second PUCCH format 0 sequence. Please refer to the description of subsequent embodiments for details.

[0179] Optionally, in the time slot reported by the SR, if the control information does not include HARQ information except resource request information, that is, the network device does not expect the terminal device to send HARQ information, then the first cyclic shift value may correspond to the first SR information, and the second cyclic shift value may correspond to the resource request information, and the first SR information indicates that the terminal device has a scheduling request. Optionally, the second cyclic shift value may be different from the first cyclic shift value. Among them, the first cyclic shift value may be 0, and the first PUCCH format 0 sequence obtained according to the first cyclic shift value may be used to indicate that the terminal device has a scheduling request.

[0180] The second cyclic shift value may be a newly configured cyclic shift value corresponding to the resource request information, for example, it may be the second cyclic shift value configured by the network device. The second cyclic shift value may be an integer greater than or equal to 0 and less than or equal to 11, for example, the second cyclic shift value may be 3 or 6 or 9. Further, the second PUCCH format 0 sequence obtained according to the second cyclic shift value is also a newly configured sequence, and the second PUCCH format 0 sequence may be used to indicate that the terminal device requests to be allocated sideline transmission resources in the first activation time period in the DRX cycle, that is, the control information indicating that the resource request information is included.

[0181] Exemplarily, in the time slot reported by SR, if the control information does not include either HARQ information or resource request information, that is, the network device does not expect the terminal device to send HARQ information, and the terminal device does not have the need for sideline transmission resources in the first activation time period in the DRX cycle, but the terminal device has an SR request, then the terminal device can obtain the first PUCCH format 0 sequence according to the first cyclic shift value, and send the first PUCCH format 0 sequence to the network device in the time slot reported by SR, and the first cyclic shift value can be 0. Accordingly, the network device can determine that the terminal device has a scheduling request based on the first cyclic shift value corresponding to the first PUCCH format 0 sequence. It can be understood that in this scenario, if the terminal device does not have an SR request, the terminal device may not send a PUCCH format 0 signal.

[0182] If the control information does not include HARQ information but includes resource request information, that is, the terminal device has a demand for uplink transmission resources in the first activation time period in the DRX cycle, the terminal device generates a first PUCCH format 0 sequence according to the first cyclic shift value and generates a second PUCCH format 0 sequence according to the second cyclic shift value. The terminal device simultaneously sends the generated first PUCCH format 0 sequence and the second PUCCH format 0 sequence to the network device in the time slot reported by the SR. For example, the two cyclic shift values ​​m cs They may be 0 and 3, or 0 and 6, or 0 and 9, etc. Accordingly, the network device receives two sequences and can determine that the control information includes resource request information and SR information. For details, please refer to the description of the subsequent embodiments and will not be described in detail.

[0183] In another optional implementation, in the time slot reported by the SR, the control information includes resource request information, but does not include HARQ information, that is, the network device does not expect the terminal device to send HARQ information, and can send a third PUCCH format 0 sequence, which is obtained according to a third cyclic shift value, and the third cyclic shift value can correspond to the resource request information. The third cyclic shift value can be a newly configured cyclic shift value corresponding to the resource request information. The third cyclic shift value can be different from the first cyclic shift value, and the first cyclic shift value can correspond to the first SR information, which indicates that the terminal device has a scheduling request, and the first cyclic shift value can be 0, wherein the description of the first cyclic shift value can specifically refer to the aforementioned embodiment, and will not be repeated here. Optionally, the third cyclic shift value can be an integer greater than or equal to 0 and less than or equal to 11, for example, the third cyclic shift value can be 3 or 6 or 9.

[0184] Furthermore, the third PUCCH format 0 sequence obtained according to the third cyclic shift value is also a newly configured sequence. The third PUCCH format 0 sequence can be used to indicate that the terminal device requests allocation of sideline transmission resources in the first activation time period in the DRX cycle, that is, to indicate that the control information includes resource request information.

[0185] Exemplarily, in the time slot reported by SR, if the control information does not include either HARQ information or resource request information, that is, the network device does not expect the terminal device to send HARQ information, and the terminal device does not have a demand for sideline transmission resources in the first activation time period in the DRX cycle, but the terminal device has an SR request, then the terminal device can obtain a first PUCCH format 0 sequence according to a first cyclic shift value, and send the first PUCCH format 0 sequence to the network device in the time slot reported by SR, and the first cyclic shift value can be 0. Accordingly, the network device can determine that the terminal device has a scheduling request, but does not have a demand for sideline transmission resources in the first activation time period in the DRX cycle, based on the first cyclic shift value corresponding to the first PUCCH format 0 sequence.

[0186] If the control information does not include HARQ information, but includes resource request information, that is, the terminal device has a demand for sideline transmission resources in the first activation time period of the DRX cycle, then the terminal device can generate a third PUCCH format 0 sequence according to the third cyclic shift value. The terminal device sends the generated third PUCCH format 0 sequence to the network device in the time slot reported by the SR. Accordingly, the network device can determine that the terminal device has a demand for sideline transmission resources in the first activation time period of the DRX cycle based on the third cyclic shift value corresponding to the third PUCCH format 0 sequence. For details, please refer to the description of the subsequent embodiments, which will not be repeated here.

[0187] 2. Use PUCCH format 1 to send control information

[0188] The network device schedules the terminal device to use PUCCH format 1 to send control information, and the control information may be bit information to be transmitted. When using PUCCH format 1 to transmit the bit information to be transmitted, when the number of bit information to be transmitted is different, different modulation methods may be used. For example, if the number of bit information to be transmitted is 1 bit, for example, the control information only includes SR information, and the SR information indicates that the UE has an SR request, and the value of the bit information to be transmitted is 0, BPSK may be used to modulate the bit information to be transmitted. If the bit information to be transmitted is 2 bits, for example, the control information includes SR information and 1 bit of HARQ information, QPSK may be used to modulate the bit information to be transmitted. For details, please refer to the description of the aforementioned embodiment, which will not be repeated here.

[0189] In an optional implementation, in the time slot reported by the SR, if the control information includes resource request information but does not include HARQ information, that is, the network device does not expect the terminal device to send HARQ information, the terminal device can determine the bit information to be transmitted based on the resource request information. In order to distinguish it from the value of the bit information to be transmitted determined according to the SR information, in this embodiment, the value of the bit information to be transmitted determined according to the resource request information is 1.

[0190] Exemplarily, in the time slot in which the SR is reported, if the control information includes SR information but does not include HARQ information and resource request information, that is, the network device does not expect the terminal device to send HARQ information, and the terminal device does not have a demand for sideline transmission resources in the first activation time period of the DRX cycle, but the terminal device has an SR request, then the terminal device determines that the value of the bit information to be transmitted is 0 based on the SR information, and uses BPSK to modulate the bit information to be transmitted. Further, the modulated bit information is sent using PUCCH format 1. Accordingly, the network device decodes the received PUCCH format 1 signal and obtains that the value of the bit information is 0, then it can be determined that the terminal device has an SR request, but does not have a demand for sideline transmission resources in the first activation time period of the DRX cycle.

[0191] If the control information includes resource request information but does not include HARQ information, that is, the network device does not expect the terminal device to send HARQ information, but the terminal device has a demand for sideline transmission resources in the first activation time period in the DRX cycle, then the terminal device determines that the value of the bit information to be transmitted is 1 based on the resource request information, and modulates the bit information to be transmitted using BPSK. Further, the modulated bit information is sent using PUCCH format 1. It can be understood that in this implementation, the value of the bit information to be transmitted is 1, which can not only indicate that the terminal device has an SR request, but also indicate that the terminal device has a demand for sideline transmission resources in the first activation time period in the DRX cycle. Accordingly, the network device decodes the received PUCCH format 1 signal and obtains that the value of the bit information is 1, then it can be determined that the control information includes resource request information, that is, it is determined that the terminal device has a demand for sideline transmission resources in the first activation time period in the DRX cycle. For details, please refer to the description of the subsequent embodiments, which will not be repeated for the time being.

[0192] In another optional implementation, in the time slot reported by SR, if the control information includes resource request information, SR information and 1-bit HARQ information, that is, the network device expects the terminal device to send 1-bit HARQ information, and the terminal device also has a demand for uplink transmission resources in the first activation time period in the DRX cycle, then the terminal device determines the bit information to be transmitted based on the 1-bit HARQ information, SR information and resource request information. The terminal device further adopts π / 4QPSK to modulate the HARQ information and SR information in the bit information to be transmitted, and uses PUCCH format 1 in the time slot reported by SR to send the modulated bit information to the network device. That is, the terminal device indicates the resource request information to the network device through different modulation methods. Correspondingly, when the bit information to be transmitted does not include resource request information, but only includes 1-bit HARQ information and SR information, the terminal device uses QPSK to modulate the HARQ information and SR information.

[0193] Exemplarily, in the time slot in which the SR is reported, if the control information includes SR information and 1-bit HARQ information, but does not include resource request information, that is, the network device expects the terminal device to send 1-bit HARQ information, but the terminal device does not have a demand for uplink transmission resources in the first activation time period in the DRX cycle, the terminal device determines the bit information to be transmitted based on the 1-bit HARQ information and the SR information, and modulates the bit information to be transmitted using QPSK. Further, the terminal device uses PUCCH format 1 to send the modulated bit information to the network device. Accordingly, after the network device receives the PUCCH format 1 signal, if it detects that the PUCCH format 1 signal is based on QPSK modulation, it can be determined that the control information does not include resource request information.

[0194] If the control information includes SR information, 1-bit HARQ information and resource request information, that is, the network device expects the terminal device to send 1-bit HARQ information, and the terminal device has a demand for sideline transmission resources in the first activation time period of the DRX cycle, the terminal device determines the bit information to be transmitted based on the 1-bit HARQ information, SR information and resource request information, and uses π / 4 quadrature phase shift keying QPSK to modulate the HARQ information and SR information in the bit information to be transmitted, and uses PUCCH format 1 to send the modulated bit information to the network device. Correspondingly, in the time slot reported by the SR, after the network device receives the signal of PUCCH format 1, if it detects that the signal of PUCCH format 1 is based on π / 4QPSK modulation, it can be determined that the control information includes resource request information, that is, it is determined that the terminal device has a demand for sideline transmission resources in the first activation time period of the DRX cycle. For details, please refer to the description of the subsequent embodiments, which will not be repeated for the time being.

[0195] In another optional implementation, in the time slot reported by SR, if the control information includes resource request information, SR information and 2-bit HARQ information, that is, the network device expects the terminal device to send 2-bit HARQ information, and the terminal device also has a demand for uplink transmission resources in the first activation time period in the DRX cycle, then the terminal device determines the bit information to be transmitted based on the 2-bit HARQ information, SR information and resource request information, and uses 16QAM to modulate the bit information to be transmitted. The terminal device further uses PUCCH format 1 to send the modulated bit information to the network device. In this implementation, since 16QAM can realize the modulation of 4-bit information, in the embodiment of the present application, 16QAM can be used to modulate all the bit information in the bit information to be transmitted.

[0196] Exemplarily, in the time slot reported by SR, if the control information includes SR information, 2-bit HARQ information and resource request information, that is, the network device expects the terminal device to send 2-bit HARQ information, and the terminal device has a demand for sideline transmission resources in the first activation time period in the DRX cycle, the terminal device determines the bit information to be transmitted according to the 2-bit HARQ information, SR information and resource request information, and modulates the bit information to be transmitted using 16QAM, and uses PUCCH format 1 to send the modulated bit information to the network device. Correspondingly, in the time slot reported by SR, if the network device expects the terminal device to send 2-bit HARQ information, after receiving the signal of PUCCH format 1, the network device decodes the signal of PUCCH format 1 based on 16QAM, thereby obtaining SR information, resource request information and 2-bit HARQ information. It can also be determined that the terminal device has a demand for sideline transmission resources in the first activation time period in the DRX cycle. For details, please refer to the description of the subsequent embodiments, which will not be repeated for the time being.

[0197] Optionally, the use of PUCCH format 1 to send modulated bit information to the network device described in the above embodiment may be that the terminal device modulates the bit information to be transmitted to generate a modulation symbol, and further modulates the modulation symbol onto the generated ZC sequence. For details, please refer to the above Figure 3 The description of the embodiments will not be repeated here.

[0198] 3. Use one of PUCCH format 2, PUCCH format 3 and PUCCH format 4 to send control information

[0199] If the network device schedules the terminal device to send control information using one of PUCCH formats 2, 3 and 4, the terminal device can encode the control information including resource request information and send the encoded control information to the network device using one of PUCCH formats 2, 3 and 4.

[0200] Optionally, one of PUCCH formats 2, 3 and 4 is used to send the encoded control information to the network device. The terminal device may perform channel coding on the control information, and further perform other operations such as scrambling and modulation on the channel-coded control information. For details, please refer to the aforementioned Figure 4 The description of the embodiments will not be repeated here.

[0201] The control information may be bit information to be transmitted, and the bit information to be transmitted may be UCI. Specifically and optionally, 1 bit of information may be added to the UCI to indicate the resource request information, so as to indicate that the terminal device has a demand for uplink transmission resources in the first activation time period of the DRX cycle.

[0202] For example, in the UCI schematic diagram shown in Table 6, 1 bit of information (ie, DRX resource request) is added at the end of the UCI to indicate the resource request information. The encoding method of the resource request information may be the same as the encoding method of the SR information.

[0203] Table 6 Schematic diagram of UCI

[0204]

[0205] S103, the network device receives control information, where the control information includes resource request information, where the resource request information is used to request allocation of sideline transmission resources in a first activation time period in a discontinuous reception DRX cycle, where the DRX cycle includes at least one activation time period.

[0206] In one embodiment, the terminal device sends the control information to the network device via PUCCH or PUSCH, and correspondingly, the network device receives the control information via PUCCH or PUSCH. If the control information is sent to the network device via PUCCH, the network device can schedule the terminal device to use one of PUCCH formats 0, 1, 2, 3, and 4 to send the control information to the network device, and correspondingly, the network device receives the signal of the corresponding PUCCH format and determines the information contained in the control information based on the received signal of the PUCCH format. The following are respectively described:

[0207] 1. The network device schedules the terminal device to use PUCCH format 0 to send control information

[0208] In an optional implementation, in the time slot reported by the SR, if the terminal device sends the first PUCCH format 0 sequence and the second PUCCH format 0 sequence, that is, the terminal device indicates resource request information to the network device by sending two PUCCH format 0 sequences. Accordingly, the network device receives the first PUCCH format 0 sequence and the second PUCCH format 0 sequence, and can determine that the control information includes resource request information, that is, it is determined that the terminal device has a demand for upper sideline transmission resources in the first activation time period of the DRX cycle.

[0209] Optionally, within the time slot reported by the SR, if the network device also expects the terminal device to send HARQ information, that is, the network device expects the control information to include HARQ information in addition to the resource request information, the network device can further obtain a first cyclic shift value corresponding to the first PUCCH format 0 sequence and a second cyclic shift value corresponding to the second PUCCH format 0 sequence, and determine the first HARQ information included in the control information based on the first cyclic shift value and / or the second cyclic shift value.

[0210] Exemplarily, in the time slot reported by the SR, if the network device expects the terminal device to send 1 bit of HARQ information, the network device can determine the first HARQ information according to the first cyclic shift value and / or the second cyclic shift value, and Table 2 and Table 3 configured for the terminal device. For example, if the first cyclic shift value and the second cyclic shift value are 6 and 9 respectively, it can be determined that the first HARQ information is 1, that is, ACK information.

[0211] Exemplarily, in the time slot reported by the SR, if the network device expects the terminal device to send 2 bits of HARQ information, the network device can determine the first HARQ information according to the first cyclic shift value and / or the second cyclic shift value, and Table 4 and Table 5 configured for the terminal device. For example, if the first cyclic shift value and the second cyclic shift value are 3 and 4 respectively, it can be determined that the first HARQ information is NACK information and ACK information, that is, the first transmission block corresponds to NACK information, and the second transmission block corresponds to ACK information.

[0212] Optionally, in the time slot in which the SR is reported, if the network device does not expect the terminal device to send HARQ information, that is, the control information does not include HARQ information except the SR information and the resource request information, then the network device can determine that the terminal device has an SR request and that the terminal device requests to be allocated a side transmission resource in the first activation time period in the DRX cycle according to the received first PUCCH format 0 sequence and the second PUCCH format 0 sequence. It can be understood that the network device can also further obtain a first cyclic shift value corresponding to the first PUCCH format 0 sequence and a second cyclic shift value corresponding to the second PUCCH format 0 sequence. If the first cyclic shift value corresponds to the first SR information, the second cyclic shift value can correspond to the resource request information, and determine that the terminal device has an SR request and that the terminal device has a demand for side transmission resources in the first activation time period in the DRX cycle, and the first SR information indicates that the terminal device has a scheduling request. In this implementation manner, please refer to the description of the terminal device side for the description of the first cyclic shift value and the second cyclic shift value, which will not be repeated here.

[0213] Exemplarily, in the time slot in which the SR is reported, if the network device does not expect the terminal device to send HARQ information, if the network device only receives the first PUCCH format 0 sequence, and the first PUCCH format 0 sequence corresponds to the first cyclic shift value, and the first cyclic shift value corresponds to the first SR request, for example, the first cyclic shift value is 0, then it can be determined that the control information includes SR information, but does not include HARQ information and resource request information, that is, the terminal device has an SR request. If the network device receives the first PUCCH format 0 sequence and the second PUCCH format 0 sequence, it can be determined that the control information includes resource request information, that is, it is determined that the terminal device has a demand for upper sideline transmission resources in the first activation time period in the DRX cycle.

[0214] In another optional implementation, in the time slot reported by the SR, the network device does not expect the terminal device to send HARQ information, the network device receives the third PUCCH format 0 sequence, and further obtains a third cyclic shift value corresponding to the third PUCCH format 0 sequence. If the third cyclic shift value is the cyclic shift value corresponding to the resource request information, it can be determined that the control information includes resource request information, that is, it is determined that the terminal device has a demand for upper line transmission resources in the first activation time period in the DRX cycle. For the description of the third cyclic shift value, please refer to the description on the terminal device side, which will not be repeated here.

[0215] 2. The network device schedules the terminal device to use PUCCH format 1 to send control information

[0216] The control information may be bit information, that is, the network device receives the bit information. Specifically, the network device may decode the signal of PUCCH format 1 to obtain the bit information. Exemplarily, the terminal device sends the control information in the time slot reported by the SR, and correspondingly, the network device may receive the control information in the time slot reported by the SR.

[0217] In an optional implementation, in the time slot reported by SR, if the network device does not expect the terminal device to send HARQ information, the network device determines that the terminal device uses BPSK to modulate the bit information. Accordingly, after receiving the signal of PUCCH format 1, the network device decodes the signal of PUCCH format 1 based on BPSK to obtain the bit information. If the value of the bit information is 1, it is determined that the control information includes resource request information, that is, it is determined that the terminal device has a demand for sideline transmission resources in the first activation time period of the DRX cycle. If the value of the bit information is 0, it is determined that the control information only includes SR information, but does not include resource request information, that is, it is determined that the terminal device only has an SR request, but does not have a demand for sideline transmission resources in the first activation time period of the DRX cycle.

[0218] In another optional implementation, in the time slot in which the SR is reported, the network device expects the terminal device to send 1 bit of HARQ information, that is, the bit information includes 1 bit of HARQ information. In order to further determine whether the bit information includes resource request information, the network device can further detect the modulation mode of the PUCCH format 1 signal after receiving the PUCCH format 1 signal. If the PUCCH format 1 signal is based on π / 4QPSK modulation, the bit information includes resource request information. Further, the network device decodes the PUCCH format 1 signal based on π / 4QPSK, thereby further obtaining 1 bit of HARQ information and SR information in the bit information. Optionally, if the PUCCH format 1 signal is based on QPSK modulation, the bit information does not include resource request information. Further, the network device decodes the PUCCH format 1 signal based on QPSK, thereby obtaining 1 bit of HARQ information and SR information in the bit information.

[0219] In another optional implementation, in the time slot reported by SR, the network device expects the terminal device to send 2 bits of HARQ information, that is, the bit information includes 2 bits of HARQ information, and the network device can determine that the terminal device modulates the bit information using 16QAM. Accordingly, after receiving the signal of PUCCH format 1, the network device decodes the signal of PUCCH format 1 based on 16QAM to obtain the bit information. The bit information includes resource request information, SR information and 2 bits of HARQ information.

[0220] 3. The network device schedules the terminal device to use one of PUCCH formats 2, 3 and 4 to send control information

[0221] Among them, if the terminal device uses PUCCH format 2 to send the encoded control information to the network device, then the network device decodes the signal of PUCCH format 2 to obtain the control information. If the terminal device uses PUCCH format 3 to send the encoded control information to the network device, then the network device decodes the signal of PUCCH format 3 to obtain the control information. If the terminal device uses PUCCH format 4 to send the encoded control information to the network device, then the network device decodes the signal of PUCCH format 4 to obtain the control information.

[0222] Optionally, before decoding, the network device may also perform descrambling, demodulation, and other operations on the PUCCH format 2 signal, the PUCCH format 3 signal, or the PUCCH format 4 signal.

[0223] S104: The network device configures side transmission resources for the terminal device in the first activation time period according to the resource request information.

[0224] In one embodiment, when the network device determines that the control information includes resource request information, a side transmission resource in the first activation time period can be configured for the terminal device. Further, the network device sends resource scheduling information to the terminal device, and the resource scheduling information is used to indicate the configured side transmission resource in the first activation time period to the terminal device. For example, the resource scheduling information may include time-frequency resource information of the side transmission resource configured by the network device.

[0225] Correspondingly, the terminal device receives the resource scheduling information and sends broadcast information or multicast information on the indicated side transmission resources.

[0226] Since the terminal devices with energy-saving requirements are configured with a unified DRX cycle, and the terminal devices with energy-saving requirements must receive information in the first activation time period of the DRX cycle, the terminal devices send broadcast information on the side transmission resources of the first activation time period, and other terminal devices can receive the broadcast information, thereby improving the reliability of receiving the broadcast information. The other terminal devices may include terminal devices with energy-saving requirements and terminal devices without energy-saving requirements.

[0227] It can be understood that if the terminal device sends multicast information on the side transmission resources in the first activation time period, it can be that a unified DRX cycle is configured for the terminal devices with energy-saving requirements within the group, and the terminal devices configured with the unified DRX cycle must receive information in the first activation time period, thereby improving the reception reliability of the multicast information.
