Description

Information transmission method and device

Technical field

This application relates to the field of communication technology, and in particular to an information transmission method and device.

Background technique

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, a discontinuous reception (DRX) technology is introduced to save power. A terminal device with energy saving needs will report an energy saving request to the base station, and the base station configures a corresponding DRX cycle for the terminal device. At least one activation time period is defined in a DRX cycle, and several configurable different activation time periods including DRX on duration (DRX on duration) may be included. During the activation time period, the terminal device monitors and receives the data of the downlink channel; in the DRX cycle except for the activation time period, the terminal device does not receive the data of the downlink channel to save power consumption.

The current DRX mechanism itself defines the functional requirements of the receiving end, that is, it specifies the receiving behavior of the terminal equipment to receive the downlink signal. In the sideline data transmission scenario, the original DRX mechanism is no longer suitable, because it cannot be simply assumed that the terminal device receiving the downlink control information has a DRX requirement.

In addition, the embodiments of the present application make full use of existing technical solutions, and on the basis of ensuring that the existing solutions are feasible, new information expression methods are added to support the expression of resource request information.

In the first aspect, embodiments of the present application provide an information transmission method, where the method may be executed by a terminal device, or may be executed by a component of the terminal device (for example, 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, and the resource request information is used to request the allocation of sideline transmission resources in the first active period of the DRX cycle, and the DRX cycle includes at least An activation period.

In a possible design, the terminal device receives resource scheduling information from the network device, and the resource scheduling information is used to indicate to the terminal device the sideline transmission resource in the first activation time period. The terminal device sends broadcast information or multicast information on the indicated side transmission resource.

Optionally, a terminal device with energy saving needs can be configured with a unified DRX cycle, and the terminal device with energy saving needs must receive information during the first activation time period of the DRX cycle. Therefore, the terminal device needs to receive information during the first activation time period. When broadcast information or multicast information is sent on the side transmission resource, other terminal devices can receive the broadcast information or multicast information, thereby improving the reliability of receiving the broadcast information or multicast information. Wherein, the other terminal devices may include terminal devices that have energy-saving requirements and terminal devices that do not have energy-saving requirements.

In a possible design, if the control information does not include HARQ information except for resource request information, that is, the network device does not expect the terminal device to send HARQ information, the first cyclic shift value may correspond to the first SR information, and the second The cyclic shift value may correspond to 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.

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, 6 or 9.

Optionally, 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. The second PUCCH format 0 sequence obtained according to the second cyclic shift value may be used to instruct the terminal device to request the allocation of side row transmission resources in the first active period of the DRX cycle.

In a 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 may send the third PUCCH format 0 sequence, which is the third PUCCH format The 0 sequence may be obtained according to the third cyclic shift value, and the third cyclic shift value may correspond to the resource request information.

Wherein, 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 first SR information, and the first SR information indicates that the terminal device has a scheduling request.

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, 6 or 9.

Wherein, the third PUCCH format 0 obtained according to the third cyclic shift value may be used to instruct the terminal device to request the allocation of side row transmission resources in the first active period of the DRX cycle.

Detailed ways

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

1. There are two main transmission modes in the side-line data transmission scenario: the mode based on base station scheduling is transmission mode 1, and the mode in which user equipment (UE) autonomously selects side-line transmission resources is transmission mode 2. The following respectively introduces transmission mode one and transmission mode two:

Transmission mode one can be used for V2X communication within the coverage of the base station. Taking dynamic scheduling as an example, the base station centrally allocates resources according to the buffer status report (BSR) of the UE. Specifically, as shown in Figure 1, the base station will indicate the time-frequency resource of the side-line data of the sending end UE through downlink control information (DCI), and the sending end UE will receive the DCI and use the time-frequency resource resources indicated by the DCI The upper side sends sidelink control information (SCI) and data to the receiving end UE. In transmission mode 1, the side-line transmission resources of each UE are uniformly scheduled by the base station, so collisions can be avoided.

The second transmission mode may mean that the UE selects the time-frequency resources used for communication among the available time-frequency resources included in the communication resource pool, and sends control messages and data on the selected time-frequency resources. In the second transmission mode, the UE’s side-line transmission resources can be selected by the UE based on the results of its own monitoring. This mode is not limited to network coverage. In the absence of network coverage, the sending UE can also use this mode. Communication.

2. Feedback of scheduling request (SR) information and BSR information

The UE may send SR information to the base station to notify the scheduler of the base station whether the UE has a scheduling request. In the subsequent embodiments of the present application, for ease of description, the UE having a scheduling request is referred to as the UE having an SR request, and the UE without a scheduling request is referred to as the UE having no SR request. For a UE that has a scheduling request, BSR information is also 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 may be carried in an uplink control channel (physical uplink control channel, PUCCH) and a physical uplink shared channel (physical uplink shared channel, PUSCH).

3. Hybrid automatic repeat request (HARQ) information

The HARQ protocol exists on both the sending end and the receiving end. The HARQ operation of the sender includes transmission and retransmission of a transport block (transport block, TB), reception and processing of acknowledgement (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 sender, the receiver receives the TB and performs a cyclic redundancy check (CRC) check on it. If the CRC check is successful, it will feed back ACK information to the sender. If the CRC check fails, the NACK information is fed back. When the sender receives the ACK information, it transmits a new TB, and if the sender receives the NACK information, it retransmits the corresponding TB.

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

4. PUCCH format

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

Form 1 PUCCH format

Among them, PUCCH format 0 and PUCCH format 1 use different sequences to feed back different information, and PUCCH formats 2 to 4 use a way of encoding UCI for feedback.

5. PUCCH format 0

PUCCH format 0 is based on the ZC sequence with low peak-to-average ratio. The specific generation method is to generate a basic sequence r(n) according to the sequence length, 0≤n<M _ZC , and generate phase rotation based on the basic sequence r(n) 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:

r ^α (n)=r*e ^jαn ,0≤n<M _ZC

For example, in the NR standard, the PUCCH format 0 sequence length is 12, that is, M _ZC = 12, and the PUCCH format 0 is based on the sequence generated in the above-mentioned manner, and supports code division multiplexing of multiple users for transmission on one RB. Since the UE needs to feed back ACK information and NACK information, that is, a user is allocated at least two sequences, corresponding to different α values. The phase rotation value α can be determined by the following formula:

Indicates the number of subcarriers in an RB, and NR defines this value as 12.

Represents the slot number corresponding to the current subcarrier interval μ in a radio frame. For PUCCH format 0, l ∈ {0, 1}, this 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 is configured by the network for each UE and represents the initial phase of the current user. The base station needs to configure different sequence cyclic shift values (Sequence cyclic shift) m _cs for users to express the ACK information or NACK information in the HARQ information, and whether there is an SR request or not. Among them, the sequence cyclic shift value m _cs It can also be called a cyclic shift value, and they can be replaced with each other. For ease of description, in the subsequent embodiments, it is called a cyclic shift value.

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

The HARQ information in Table 4 and Table 5 is 2 bits, and Table 4 is used to indicate the m _cs corresponding to different HARQ information when the UE has no SR request. _{Table 5 is used to indicate the m cs} corresponding to different HARQ information when the UE has an SR request.

Where the HARQ-ACK Value of 0 can be used to indicate that the HARQ information is NACK information, and the HARQ-ACK Value of 1 can be used to indicate that the HARQ information is ACK information.

According to the above configuration parameters, a cyclic offset parameter α of a phase can be uniquely determined, and the PUCCH format 0 sequence can be determined by the α. The specific calculation process can be referred to as shown in Figure 2. That is, a m _cs _{can be determined according to HARQ information and/or SR information, and the phase rotation factor can be calculated according to the parameters such as m 0} configured by the higher layer, so as to generate and transmit according to the generated base sequence. Data, namely PUCCH format 0 sequence.

Optionally, HARQ information and SR information can be transmitted separately using PUCCH format 0. For example, if the UE needs to feed back HARQ information in a non-SR reporting time slot, PUCCH format 0 can be used separately 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 feed back 1-bit HARQ information. If Table 4 is configured, it means that the base station expects the UE to feed back 2-bit HARQ information.

For another example, in the time slot reported by the SR, the UE does not receive the scheduling information of the data, so there is no need to feed back HARQ information, that is, the base station does not expect the UE to feed back HARQ information, and PUCCH format 0 can be used alone to transmit SR information. In this scenario, the base station may configure a sequence for the UE, that is, the sequence represented by _{m cs =0.} If the UE has no SR request, the SR information may not be reported, that is, no PUCCH format 0 signal is sent. If the UE has an SR request, it can send the PUCCH format 0 sequence represented by _{m cs =0.}

Optionally, HARQ information and SR information can also be bound together and transmitted using PUCCH format 0. For example, in the time slot reported by the SR, the UE needs to feed back HARQ information. If the base station expects the UE to feed back 1-bit 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 feed back HARQ information. If the UE has an SR request, the UE selects Table 3 to feed back HARQ information.

If the base station expects the UE to feed back 2-bit 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 feed back HARQ information. If the UE has an SR request, the UE selects Table 5 to feed back HARQ information.

In the above scenario, the UE will determine an m _cs according to HARQ information and/or SR information, and generate a corresponding PUCCH format 0 sequence according to the m _cs , and send it to the base station.

6. PUCCH format 1

PUCCH format 1 still supports multiple users to multiplex on the same time-frequency resource, and the transmitted signal is based on the ZC sequence with low peak-to-average ratio for further coding and modulation. The number of users that support multiplexing on the same time-frequency resource is determined by the number of continuous symbols in the time domain except for the pilot on the PUCCH

Decide. Unlike PUCCH format 0, the ZC sequence of PUCCH format 1 does not carry any information. The ZC sequences r ^α (n) of multiple users multiplexed on the same time-frequency resource are exactly the same. The specific process is shown in Figure 3. Show.

As shown in FIG. 3, the same base station are multiplexed on the same time-frequency resources configured by the user m _0, thereby generating the same ZC sequence r α ^(n), n denotes a 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 method is BPSK, and if b(0) is 2 bits, the modulation method is QPSK.

Further modulate d(0) onto the generated ZC sequence, that is, ^{multiply each r α} (n) to generate y(n)=d(0)*r ^α (n).

Generate an orthogonal spreading factor on symbol m according to user i

And the w _i (m) of each y (n) are multiplied to generate an output sequence z (m, n) = y (n) * w i (m) on each symbol.

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

For another example, in the time slot reported by the SR, the UE does not receive data and therefore does not need to feed back HARQ information. That is, the base station does not expect the UE to feed back HARQ information, and PUCCH format 1 can be used alone to transmit SR information. In this scenario, if the UE has no 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 BPCK is used to modulate the bit information b(0) to be transmitted.

Optionally, HARQ information and SR information can also be bound together and transmitted using PUCCH format 1. For example, in the time slot reported by the SR, the UE needs to feed back HARQ information. If the base station expects the UE to feed back 1-bit HARQ information, both SR information and 1-bit HARQ information can be transmitted using PUCCH format 1. The bit information b(0) to be transmitted is 2 bits, and the bit information to be transmitted b( 0) Perform modulation. If the base station expects the UE to feed back 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 QPSK is used to transmit the bit information to be transmitted. b(0) is modulated.

7. PUCCH format 2/3/4

PUCCH format 2/3/4 may carry one or more of information including HARQ information, SR information, link recovery request (LRR) and channel state information (CSI). The control information that needs to be sent (which can be referred to as bit information to be transmitted) can be transmitted through the encoding method shown in FIG. 4. As shown in Figure 4, 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 transform precoding shown in the dashed box, while PUCCH format 3 can No transform precoding step is performed. After receiving the PUCCH report information, the base station side obtains corresponding control information through decoding and analysis.

8. DRX

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 UE, thereby increasing the use time of the mobile battery. Therefore, DRX technology is introduced for power saving. The UE can be configured with several consecutive DRX cycles (DRX cycles). A DRX cycle defines the activation time (active time), which can include a set of several configurable different activation time periods including DRX On Duration. In the NR system, the DRX on time period can be set by parameters drx-onDurationTimer indication. Several configurable different activation time periods included in a DRX cycle may be continuous or non-continuous in time. During the active time period in a DRX cycle, the UE monitors and receives the PDCCH; in the DRX cycle except for the active time period, the UE does not receive downlink channel data to save power consumption.

The resource request information in the embodiment of this application is used to request the allocation of side-line transmission resources in the first active time period in the DRX cycle. The first active time period may be the DRX on time period in the DRX cycle (DRX On Duration) It is understandable that other activation time periods may also be used, which is not limited in the embodiment of the present application. Wherein, the first activation time period may include one or more activation time periods.

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

In the embodiments of this application, the network device expects the terminal device to send HARQ information can also be referred to as the network device has HARQ information feedback expectation, for example: the network device sends data to the terminal device, correspondingly, the terminal device has demodulation of the received data Therefore, the terminal device needs to send HARQ information to the network device.

The network device does not expect the terminal device to send HARQ information. It can also be said that the network device has no HARQ information feedback expectation. For example, the network device does not send data to the terminal device. Correspondingly, the terminal device does not receive the demodulation information of the data. Therefore, the terminal The device will not send HARQ information to the network device.

This application can be applied to the transmission mode 1 of the side-line data transmission scenario. If the receiving UE (also called receiving terminal device, or receiving user, etc.) on the sidelink link has energy saving requirements, DRX is introduced The mechanism is to configure the DRX cycle for the receiving UE. Before sending data to the receiving UE, the sending UE on the sidelink link (also called the sending terminal device, or sending user, etc.) requests the base station corresponding to the active time period in the DRX cycle of the receiving UE. Sideline transmission resources, so that the receiving UE can receive the data sent by the sending UE.

In the broadcast service scenario, the originating UE does not know what the receiving UE has before sending data. Therefore, when the originating UE requests side transmission resources from the base station, it cannot determine the DRX cycle of the receiving UE and cannot guarantee the reception of all broadcast service data. reliability.

In order to support the DRX mechanism of the broadcast service scenario, a unified DRX cycle can be configured for all UEs with energy-saving requirements. For example, it is defined that all UEs with energy-saving requirements must receive information during the first active time period of the DRX cycle. The first activation period may be a DRX on period (DRX On Duration). This application provides multiple ways to facilitate the originating UE to request the base station to allocate side-line transmission resources in the first active period of 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.

It is understandable that this application can also be applied to a multicast service scenario, which is not limited in the embodiment of this application.

In the description of the subsequent embodiments, when the network device receives the resource request information of the terminal device, it is determined that the terminal device requests to allocate the side-line transmission resources in the first active period of the DRX cycle, and it can also be considered that the terminal device There is a resource scheduling request. Therefore, when the resource request information in the embodiment of the present application expresses a sideline transmission resource request in the first activation time period, it may additionally express SR information used to indicate that the terminal device has an SR request.

In addition, the resource request information mentioned in the embodiments of the present application are all used to request the allocation of side row transmission resources in the first active period of the DRX cycle.

Please refer to FIG. 6, which is a schematic flowchart of an information transmission method provided by an embodiment of this application. As shown in the figure, the information transmission method of an embodiment of this application includes but is not limited to the following steps:

S101. The terminal device determines control information, where the control information includes resource request information, and the resource request information is used to request the allocation of sideline transmission resources in the first active period of the discontinuous reception DRX cycle, where the DRX cycle includes At least one activation period.

In an embodiment, the control information may be UCI, and the control information includes resource request information.

Optionally, the first activation period may be a DRX on period (DRX On Duration) in a DRX cycle.

S102: The terminal device sends the control information to the network device.

In an embodiment, the terminal device may send the control information to the network device through PUCCH or PUSCH. Among them, if the control information is sent to the network device through PUCCH, one of PUCCH format 0, PUCCH format 1, PUCCH format 2, PUCCH format 3, and PUCCH format 4 can be used to send the control information. The above-mentioned PUCCH format sends the control information for explanation. Optionally, the control information in the embodiment of the present application may be sent in the time slot reported by the SR, where the time slot reported by the SR can be understood as the SR information can be sent periodically, that is, the time slot for reporting the SR information can be defined Of course, the terminal device can send SR information through control information in the time slot reported by SR, or 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 can be HARQ For information, refer to the description of the subsequent embodiments for details), 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 in the time slot reported by the SR, the SR information and other information can be sent together in the time slot reported by the SR, and the SR information is used to indicate whether the terminal device has a scheduling request .

1. Use PUCCH format 0 to send control information

The network device schedules the terminal device to use PUCCH format 0 to send control information. Because PUCCH format 0 expresses different information in the control information through different sequences, and the different sequences are determined by the configured different cyclic shift values m _cs . For details, reference may be made to different information corresponding _{to different cyclic shift values m cs} in Table 2 to Table 5 in the foregoing embodiment.

In an optional implementation manner, in the time slot reported by the SR, when the control information includes resource request information, the first PUCCH format 0 sequence and the second PUCCH format 0 sequence may be sent, that is, the terminal device may send two A PUCCH format 0 sequence indicates the resource request information to the network device. Wherein, 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 The shift value may be a value in a pre-configured set of cyclic shift values. The pre-configured set of cyclic shift values may include at least two cyclic shift values. In some possible designs, the set of cyclic shift values may only include the first cyclic shift value and the second cyclic shift value.

Optionally, in the time slot reported by the SR, if the control information includes HARQ information in addition to the resource request information, that is, the network device expects the terminal device to send HARQ information, the terminal device can determine the first cycle according to the HARQ information The shift value and the second cyclic shift value. 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, and the first SR information indicates the terminal equipment There is a scheduling request, and the second SR information indicates that the terminal device does not have a scheduling request. The first HARQ information may be HARQ information that the terminal device prepares to feed back.

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 HARQ information, the network device may configure the terminal device with Table 2 and Table 2 in the foregoing embodiment. Form 3. Among them, the cyclic shift values contained in Table 2 and Table 3 may constitute a pre-configured cyclic shift value set. _{The terminal device determines two cyclic shift values m cs} from Table 2 and Table 3 according to the 1-bit first HARQ information to be fed back, respectively, as the first cyclic shift value and the second cyclic shift value, and according to the first A cyclic shift value generates a first PUCCH format 0 sequence, and a second PUCCH format 0 sequence is generated according to a 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, if the 1-bit first HARQ information is ACK information, that is, the HARQ-ACK Value is 1, the two cyclic shift values m _cs may be 6 and 9 respectively; if the 1-bit first HARQ information is NACK information, That is, the HARQ-ACK Value is 0, and the two cyclic shift values m _cs can be 0 and 3 respectively.

Exemplarily, 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, the network device may configure Table 4 and Table 5 for the terminal device. Among them, the cyclic shift values contained in Table 4 and Table 5 may constitute a pre-configured cyclic shift value set. _{The terminal device determines two cyclic shift values m cs} from Table 4 and Table 5 according to the 2-bit first HARQ information to be fed back, respectively, as the first cyclic shift value and the second cyclic shift value, and according to the first A cyclic shift value generates a first PUCCH format 0 sequence, and a second cyclic shift value generates a second PUCCH format 0 sequence. 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, if the 2-bit first HARQ information is NACK information and NACK information, that is, the HARQ-ACK Value is 00, 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, the two cyclic shift values m _cs can be 3 and 4 respectively, and the others can be deduced by analogy. Wherein, the first HARQ information is NACK information and NACK information, which may indicate that the HARQ information corresponding to the two transport blocks are all NACK information. The first HARQ information is NACK information and ACK information, which may indicate that the HARQ information corresponding to the first transport block is NACK information, the HARQ information corresponding to the second transport block is ACK information, and so on.

Correspondingly, the network device can determine the resource request 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 For the information, SR information, and first HARQ information, please refer to the description of the subsequent embodiments for details, and will not be repeated here.

Optionally, in the time slot reported by the SR, if the control information does not include HARQ information except for resource request information, that is, the network device does not expect the terminal device to send HARQ information, the first cyclic shift value may correspond to the first SR Information, the second cyclic shift value may correspond to 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. 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.

Wherein, the second cyclic shift value may be a newly configured cyclic shift value corresponding to the resource request information, for example, may be the second cyclic shift value configured by a 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, 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 allocate the first activation time in the DRX cycle The side-line transmission resource on the segment indicates that the control information includes resource request information.

Exemplarily, in the time slot reported by SR, if the control information not only does not include HARQ information, but also does not include 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 first DRX cycle. If the terminal device has an SR request in the activation time period, the terminal device can obtain the first PUCCH format 0 sequence according to the first cyclic shift value, and send this to the network device in the time slot reported by the SR For the first PUCCH format 0 sequence, the first cyclic shift value may be 0. Correspondingly, the network device may determine that the terminal device has a scheduling request according to the first cyclic shift value corresponding to the first PUCCH format 0 sequence. It is understandable that in this scenario, if the terminal device does not have an SR request, the terminal device may not send a signal of PUCCH format 0.

If the control information does not include HARQ information, but includes resource request information, that is, the terminal device has a requirement for side transmission resources in the first active period of the DRX cycle, the terminal device generates the first PUCCH format according to the first cyclic shift value 0 sequence, the second PUCCH format 0 sequence is generated 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 may be 0 and 3 respectively, or may be 0 and 6, respectively, or may be 0 and 9 respectively, and so on. Correspondingly, when the network device receives the two sequences, it can be determined that the control information includes resource request information and SR information. For details, reference may be made to the description of the subsequent embodiments, which will not be repeated here.

In another optional implementation manner, 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 may send the third PUCCH format 0 sequence, the third PUCCH format 0 sequence is obtained according to the third cyclic shift value, and the third cyclic shift value may correspond to the resource request information. 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, the first cyclic shift value may correspond to first SR information, the first SR information indicates that the terminal device has a scheduling request, and the first cyclic shift value It may be 0, where the description of the first cyclic shift value can be specifically referred to the foregoing embodiment, which will not be repeated here. Optionally, 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, 6 or 9.

Further, the third PUCCH format 0 sequence obtained according to the third cyclic shift value is also a newly configured sequence, and the third PUCCH format 0 sequence may be used to indicate that the terminal device requests to allocate the first activation time in the DRX cycle The side-line transmission resource on the segment indicates that the control information includes resource request information.

Exemplarily, in the time slot reported by SR, if the control information not only does not include HARQ information, but also does not include 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 first DRX cycle. In the activation time period, the side line transmission resource needs, but the terminal device has an SR request, the terminal device can obtain the first PUCCH format 0 sequence according to the first cyclic shift value, and send it to the network device in the time slot reported by the SR For the first PUCCH format 0 sequence, the first cyclic shift value may be 0. Correspondingly, the network device may determine, according to the first cyclic shift value corresponding to the first PUCCH format 0 sequence, that the terminal device has a scheduling request, but there is no demand for side-line transmission resources in the first active period of the DRX cycle.

If the control information does not include HARQ information, but includes resource request information, that is, the terminal device has a demand for side transmission resources in the first active period of the DRX cycle, the terminal device may generate the third PUCCH according to the third cyclic shift value Format 0 sequence. The terminal device sends the generated third PUCCH format 0 sequence to the network device in the time slot reported by the SR.

2. Use PUCCH format 1 to send control information

The network device schedules the terminal device to send control information using PUCCH format 1, and the control information may be bit information to be transmitted. When using PUCCH format 1 to transmit bit information to be transmitted, when the number of bit information to be transmitted is different, different modulation methods can be used, for example, if the number of bit information to be transmitted is 1 bit, for example, control information Only the SR information is included, the SR information indicates that the UE has an SR request, and the value of the bit information to be transmitted is 0, and the bit information to be transmitted can be modulated by BPSK. If the bit information to be transmitted is 2 bits, for example, the control information includes SR information and 1-bit HARQ information, QPSK can be used to modulate the bit information to be transmitted. For details, please refer to the description of the foregoing embodiment, which will not be omitted here. Go into details.

In order to distinguish 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.

Exemplarily, in the time slot reported by SR, 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 the first DRX cycle. An active time period is required for side-line transmission resources, but the terminal device has an SR request, the terminal device determines the value of the bit information to be transmitted is 0 according to the SR information, and uses BPSK to modulate the bit information to be transmitted . Further, PUCCH format 1 is used to transmit modulated bit information. Correspondingly, 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 there is no upper row transmission resource in the first active period of the DRX cycle Demand.

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 upstream transmission resources in the first active period of the DRX cycle, then the terminal device according to the resource Request information, determine that the value of the bit information to be transmitted is 1, and use BPSK to modulate the bit information to be transmitted.

The terminal device further uses π/4QPSK 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 in the time slot reported by the SR. That is, the terminal device indicates the resource request information to the network device through the difference of the modulation mode. Correspondingly, when the bit information to be transmitted does not include resource request information and only includes 1-bit HARQ information and SR information, the terminal device uses QPSK to modulate the HARQ information and SR information.

Exemplarily, in the time slot reported by SR, if the control information includes SR information and 1-bit HARQ information, it 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 exist In the DRX cycle, in the first active time period, the terminal device determines the bit information to be transmitted according to the 1-bit HARQ information and SR information, and modulates the bit information to be transmitted by using QPSK. Further, the terminal device uses PUCCH format 1 to send modulated bit information to the network device. Correspondingly, after the network device receives the signal of PUCCH format 1, if it detects that the signal of PUCCH format 1 is based on QPSK modulation, it can be determined that the control information does not include resource request information.

The terminal device further uses PUCCH format 1 to send modulated bit information to the network device. In this embodiment, because 16QAM can implement modulation of 4-bit information, in this embodiment of the present application, 16QAM can be used to modulate all bit information in the bit information to be transmitted.
