Description

Information transmission method and device Technical Field
The present application relates to the field of communications technologies, and in particular, to an information transmission method and apparatus.
Background
The generation of the data packets is not continuous, and the power consumption can be reduced by turning off the receiving circuit of the terminal device when no data is transmitted. Discontinuous Reception (DRX) techniques have therefore been introduced for power saving. The terminal equipment with the energy-saving requirement reports an energy-saving request to the base station, and the base station configures a corresponding DRX period for the terminal equipment. At least one active period is defined in one DRX cycle, and several configurable different active periods may comprise a DRX on period (DRX on duration). In the activation time period, the terminal equipment monitors and receives data of a downlink channel; in other time periods except the active time period in the DRX period, the terminal equipment does not receive data of a downlink channel so as to save power consumption.
The current DRX mechanism itself defines the functional requirements of the receiving end, i.e. specifies the receiving behavior of the terminal device for receiving downlink signals. In the sidestream data transmission scenario, the original DRX mechanism is no longer suitable, because the terminal device receiving the downlink control information cannot be simply considered to have DRX requirements.
Disclosure of Invention
The embodiment of the application provides an information transmission method and an information transmission device, which can be applied to the internet of vehicles, such as V2X communication, long term evolution-vehicle (LTE-V) communication, vehicle to vehicle (V2V) communication and the like, or can be applied to the fields of intelligent driving, intelligent internet connection and the like, and can request a sidestream transmission resource on a first activation time period in a DRX period for a terminal device, so that a DRX mechanism is applied to a sidestream data transmission scene, and the power consumption of the terminal device for receiving sidestream data is reduced. In addition, the embodiment of the application makes full use of the prior art scheme, and adds a new information expression mode on the basis of ensuring the feasibility of the prior scheme so as to support the expression of the resource request information.
In a first aspect, an embodiment of the present application provides an information transmission method, where the method may be performed by a terminal device, and may also be performed by a component (e.g., a processor, a chip, or a system-on-chip) of the terminal device. The information transmission method may include: the terminal device determines control information comprising resource request information for requesting a sidelink transmission resource allocated on a first active period in a DRX cycle comprising at least one active period.
The first active time period in the embodiment of the present application may be one or more active time periods in at least one active time period included in the DRX cycle. Alternatively, the first active period may be a DRX On period (DRX On Duration) in the DRX cycle.
Optionally, the control information may include, in addition to the resource request information, SR information and/or hybrid automatic repeat request (HARQ) information, which is not limited in the embodiment of the present application.
The terminal device sends control information to the network device. The terminal device may send the control information to the network device through a Physical Uplink Control Channel (PUCCH) or a Physical Uplink Shared Channel (PUSCH). Here, if the control information is transmitted to the network device through the PUCCH, the control information may be transmitted using one of PUCCH formats 0,1, 2, 3, and 4.
Correspondingly, the network device receives the control information and configures the sideline transmission resource on the first activation time period for the terminal device according to the resource request information included in the control information.
By implementing the embodiment of the application, the terminal device can request the network device to allocate the sidestream transmission resource on the first active time period in the DRX period through the resource request information, so that the DRX mechanism is applied to a sidestream data transmission scene, and the power consumption of the terminal device receiving sidestream data is reduced.
In one possible design, the terminal device receives resource scheduling information from the network device, the resource scheduling information indicating to the terminal device a sidelink transmission resource over a first active time period. And the terminal equipment transmits the broadcast information or the multicast information on the indicated sideline transmission resource.
Optionally, the terminal device with the energy saving requirement may configure a uniform DRX cycle, and the terminal device with the energy saving requirement must receive information in the first active time period of the DRX cycle, so that when the terminal device sends broadcast information or multicast information on the sideline transmission resource of the first active time period, other terminal devices may 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 a terminal device with an energy saving requirement and a terminal device without an energy saving requirement.
By implementing the embodiment, the terminal device sends the broadcast information or the multicast information on the sideline transmission resource on the first activation time period configured by the network device, and the reliability of the broadcast information or the multicast information transmission can be improved.
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 the first PUCCH format0 sequence and the second PUCCH format0 sequence, that is, the terminal device indicates the resource request information to the network device by sending the two PUCCH format0 sequences.
Wherein the first PUCCH format0 sequence is obtained according to a first cyclic shift value, and the second PUCCH format0 sequence is obtained according to a second cyclic shift value. Alternatively, the first and second cyclic shift values may be values in a preconfigured 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 include only the first cyclic shift value and the second cyclic shift value, and the embodiment of the present application is not limited thereto.
By implementing the embodiment, the terminal device can indicate that the control information includes the resource request information to the network device by sending the two PUCCH format0 sequences, so that the network device can determine that the control information includes the resource request information conveniently.
In one possible design, the control information includes HARQ information in addition to the resource request information, that is, the network device expects the terminal device to send the HARQ information, and the terminal device may determine the first cyclic shift value and the second cyclic shift value according to the HARQ information.
By implementing the embodiment, the first PUCCH format0 sequence and the second PUCCH format0 sequence transmitted by the terminal device may indicate, to the network device, not only the resource request information included in the control information, but also HARQ information included in the control information, so as to increase the information type carried in the PUCCH format0 sequence.
In one possible design, the first cyclic shift value corresponds to first HARQ information and first scheduling request, SR, information, and the second cyclic shift value corresponds to the first HARQ information and second scheduling request, SR, information, where the first SR information indicates that a scheduling request exists for the terminal device, and the second SR information indicates that a scheduling request does not exist for the terminal device, and the first HARQ information may be HARQ information that the terminal device prepares to feed back.
By implementing the 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 which are prepared and fed back by the terminal equipment, and a new cyclic shift value is not required to be added to represent the resource request information, so that the compatibility is strong.
In one possible design, if the control information does not include HARQ information other than the 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 cyclic shift value may correspond to the resource request information, where the first SR information indicates that the terminal device has a scheduling request. Alternatively, the second cyclic shift value may be different from the first cyclic shift value.
Illustratively, 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.
Optionally, the first PUCCH format0 sequence obtained according to the first cyclic shift value may be used to indicate that the terminal device has a scheduling request. A second PUCCH format0 sequence derived from the second cyclic shift value may be used to instruct the terminal device to request allocation of sidelink transmission resources on the first active period in the DRX cycle.
By implementing this embodiment, in a scenario where HARQ information is not included in the control information, the terminal device may indicate, to the network device, the resource request information and SR information included in the control information by transmitting two PUCCH format0 sequences.
Alternatively, the second cyclic shift value may be network device configured.
In one possible design, if the control information includes the resource request information but does not include the HARQ information, that is, the network device does not expect the terminal device to transmit the HARQ information, the terminal device may transmit a third PUCCH format0 sequence, where the third PUCCH format0 sequence may be obtained according to a 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 indicating that the terminal device has a scheduling request.
Illustratively, 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.
Wherein, the third PUCCH format0 obtained according to the third cyclic shift value may be used to instruct the terminal device to request allocation of the sidelink transmission resource on the first active time period in the DRX cycle.
By implementing this embodiment, the third PUCCH format0 sequence obtained by the newly configured third cyclic shift value indicates the resource request information included in the control information, that is, the resource request information included in the control information may be indicated to the network device in a scenario in which the control information does not include HARQ information, and the number of PUCCH format0 sequences to be transmitted is reduced.
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 the resource request information but does not include the HARQ information, that is, the network device does not expect the terminal device to send the HARQ information, the terminal device may determine bit information to be transmitted, that is, the control information, according to the resource request information, where a value of the bit information to be transmitted is 1.
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 may determine bit information to be transmitted according to the SR information, where a value of the bit information to be transmitted is 0.
By implementing the embodiment, the resource request information is included in the control information indicated to the network equipment through the difference of the values of the bit information to be transmitted, without adding new bits, and the overhead is small.
Further optionally, the terminal device may modulate the bit information to be transmitted by using Binary Phase Shift Keying (BPSK), and send the modulated bit information to the network device by using PUCCH format 1.
By implementing the embodiment, BPSK can still be adopted to modulate the bit information to be transmitted, so that the existing modulation mode is not changed, and the compatibility is strong.
In one possible design, the terminal device may determine bit information to be transmitted, i.e., control information, according to the HARQ information, the SR information, and the resource request information.
Alternatively, the HARQ information may be 1 bit or 2 bits.
Illustratively, the network device expects the terminal device to send 1-bit HARQ information, and the terminal device also has a requirement for uplink transmission resources in the first active time period in the DRX cycle, and then the terminal device determines bit information to be transmitted according to the 1-bit HARQ information, SR information, and resource request information.
Illustratively, the network device expects the terminal device to send 2-bit HARQ information, and the terminal device also has a requirement for uplink transmission resources in the first active time period in the DRX cycle, and then the terminal device determines bit information to be transmitted according to the 2-bit HARQ information, the SR information, and the resource request information.
By implementing the embodiment, the bit information to be transmitted can carry the resource request information, which is convenient for the network device to allocate the sidelink transmission resource on the first active time period in the DRX cycle for the terminal device.
In a possible design, when the bit information to be transmitted includes 1-bit HARQ information, SR information, and resource request information, the terminal device may modulate 1-bit HARQ information and SR information in the bit information to be transmitted by using pi/4 Quadrature Phase Shift Keying (QPSK), and send the modulated bit information to the network device using PUCCH format 1 in a timeslot reported by the SR.
It can be understood that, if the bit information to be transmitted does not include the resource request information, but only includes 1-bit HARQ information and SR information, the terminal device may modulate the 1-bit HARQ information and SR information by using QPSK.
By implementing the embodiment, the terminal device indicates the resource request information to the network device through different modulation modes, thereby increasing the number of bit information that can be carried by the signal of the PUCCH format 1.
In a possible design, when the bit information to be transmitted includes 2-bit HARQ information, SR information, and resource request information, the terminal device may modulate the bit information to be transmitted by using 16QAM, and send the modulated bit information to the network device using PUCCH format 1 in a timeslot reported by SR.
By implementing the embodiment, the terminal device may modulate the bit information to be transmitted by adopting a higher-order modulation mode, so as to increase the number of bits that can be carried by the signal of the PUCCH format 1.
In one possible design, the terminal device may encode the control information and transmit the encoded control information to the network device using one of PUCCH format 2, PUCCH format 3, or PUCCH format 4. Optionally, after the terminal device encodes the control information, the terminal device may further perform other operations such as scrambling and modulating on the encoded control information, and the embodiment of the present application is not limited.
Optionally, the control information may be UCI, and may be 1-bit information added to the UCI to indicate resource request information.
By implementing the embodiment, the terminal device may indicate the resource request information to the network device using one of PUCCH format 2, PUCCH format 3, or PUCCH format 4.
In a second aspect, embodiments of the present application provide an information transmission method, where the method may be performed by a network device, or may be performed by a component (e.g., a processor, a chip, or a system-on-chip) of the network device. The information transmission method may include: the network device receives control information including resource request information for requesting a sidelink transmission resource allocated on a first active period in a DRX cycle, the DRX cycle including at least one active period.
Further, the network device may configure a sidelink transmission resource on the first activation time period for the terminal device according to the resource request information. Optionally, the network device may indicate the configured sidelink transmission resource to the terminal device through the resource scheduling information, so that the terminal device sends the broadcast information or the multicast information on the indicated sidelink transmission resource.
By implementing the embodiment of the application, the network device can allocate the sidestream transmission resource on the first active time period in the DRX period to the terminal device according to the resource request information, so that the DRX mechanism is applied to a sidestream data transmission scene, and the power consumption of the terminal device receiving sidestream data is reduced.
It is to be understood that the terminal device may transmit the control information to the network device through the PUCCH or the PUSCH, and accordingly, the network device receives the control information through the PUCCH or the PUSCH. If the control information is sent to the network device through the PUCCH, the network device may schedule the terminal device to send the control information to the network device using one of PUCCH formats 0,1, 2, 3, and 4, and accordingly, the network device receives a signal of the corresponding PUCCH format and determines information included in the control information according to the received signal of the PUCCH format.
In a possible design, the network device schedules the terminal device to transmit the control information using PUCCH format0, and if the terminal device transmits the first PUCCH format0 sequence and the second PUCCH format0 sequence, the terminal device indicates the resource request information to the network device by transmitting two PUCCH format0 sequences. Correspondingly, the network device receives the first PUCCH format0 sequence and the second PUCCH format0 sequence, and may determine that the control information includes resource request information, that is, determine that the terminal device has a need for uplink transmission resources in the first active period in the DRX cycle.
Wherein the first PUCCH format0 sequence is derived from a first cyclic shift value and the second PUCCH format0 sequence is derived from a second cyclic shift value, the first and second cyclic shift values being values of a preconfigured set of cyclic shift values.
By implementing this embodiment, the network device may determine the resource request information included in the control information through two PUCCH format0 sequences transmitted by the terminal device.
In a possible design, if the network device further expects the terminal device to transmit HARQ information, that is, the control information further includes HARQ information in addition to the resource request information, the first cyclic shift value and the second cyclic shift value may be determined according to the HARQ information included in the control information.
The network device may obtain a first cyclic shift value corresponding to the first PUCCH format0 sequence and a second cyclic shift value corresponding to the second PUCCH format0 sequence, and determine HARQ information included in the control information according to the first cyclic shift value and/or the second cyclic shift value.
By implementing the embodiment, the first PUCCH format0 sequence and the second PUCCH format0 sequence may indicate not only resource request information but also HARQ information, and increase the indicated information type.
In one possible design, the first cyclic shift value may correspond to first HARQ information and first scheduling request SR information, and the second cyclic shift value may correspond to the first HARQ information and second scheduling request SR information, where 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 HARQ information fed back to the network device by the terminal device.
By implementing the embodiment, the indication resource request information can be added while indicating the first HARQ information on the basis of the existing cyclic shift value set, and the compatibility is strong.
In one possible design, if the network device does not expect the terminal device to transmit HARQ information, that is, the control information does not include HARQ information except SR information and resource request information, the network device may determine that the terminal device has an SR request according to the received first PUCCH format0 sequence and second PUCCH format0 sequence, and the terminal device requests allocation of a sidelink transmission resource on the first active period in the DRX cycle.
Optionally, the first cyclic shift value may correspond to first SR information, and the second cyclic shift value may correspond to resource request information, where the first SR information indicates that the terminal device has a scheduling request.
The network device may also further obtain a first cyclic shift value corresponding to the first PUCCH format0 sequence and a second cyclic shift value corresponding to the second PUCCH format0 sequence, and if the first cyclic shift value corresponds to the first SR information and the second cyclic shift value corresponds to the resource request information, determine that the terminal device has an SR request and the terminal device has a requirement for uplink transmission resources in the first active period in the DRX cycle.
By implementing this embodiment, when the network device does not expect the terminal device to transmit HARQ information, the network device may determine, through the received first PUCCH format0 sequence and second PUCCH format0 sequence, the resource request information and the first SR information included in the control information.
In a 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 second cyclic shift value is indicated to the terminal device.
In a possible design, if the network device does not expect the terminal device to send the HARQ information, that is, the control information does not include the HARQ information, the network device receives a third PUCCH format0 sequence, and further obtains a third cyclic shift value corresponding to the third PUCCH format0 sequence, and if the third cyclic shift value is a cyclic shift value corresponding to the resource request information, it may be determined that the control information includes the resource request information, that is, it may be determined that the terminal device has a requirement for uplink transmission resources in the first active time period in the DRX cycle.
Optionally, the third cyclic shift value is an integer greater than or equal to 0 and less than or equal to 11.
By implementing this embodiment, the third PUCCH format0 sequence obtained by the newly configured third cyclic shift value indicates the resource request information included in the control information, that is, the resource request information included in the control information may be indicated to the network device in a scenario where the control information does not include HARQ information, and the number of PUCCH format0 sequences to be transmitted is reduced.
In a possible design, the network device schedules the terminal device to transmit control information (i.e., bit information) using PUCCH format 1, and if the network device does not expect the terminal device to transmit 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, and accordingly, after receiving the signal of PUCCH format 1, the network device decodes the signal of PUCCH format 1 based on BPSK, thereby obtaining 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 requirement for uplink transmission resources in the first active time period in the DRX cycle.
By implementing the 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.
In a possible design, if the network device expects the terminal device to send 1-bit HARQ information, that is, the bit information includes 1-bit HARQ information, in order to further determine whether the bit information includes resource request information, after receiving the signal in PUCCH format 1, the network device may further detect the modulation scheme of the signal in PUCCH format 1.
If the PUCCH format 1 signal is pi/4 QPSK modulated, the bit information includes resource request information. Further, the network device decodes the signal of the PUCCH format 1 based on pi/4 QPSK, thereby further obtaining 1-bit HARQ information and SR information in the bit information, except for the included resource request information.
By implementing the embodiment, the terminal device indicates the resource request information to the network device through different modulation modes, thereby increasing the number of bit information that can be carried by the signal of the PUCCH format 1.
In a possible design, if the network device expects the terminal device to send 2-bit HARQ information, that is, the bit information includes 2-bit HARQ information, the network device may determine that the terminal device modulates the bit information by using 16QAM, and accordingly, after receiving the signal in PUCCH format 1, the network device decodes the signal in PUCCH format 1 based on 16QAM to obtain the bit information. Wherein the bit information includes resource request information, SR information, and 2-bit HARQ information.

Detailed Description
First, before describing embodiments of the present application, names or terms referred to in the embodiments of the present application are introduced.
1. There are mainly two transmission modes in the sideline data transmission scene: based on the mode of base station scheduling being transmission mode one, user Equipment (UE) autonomously selects the mode of sidelink transmission resource as transmission mode two. The following describes transmission mode one and transmission mode two, respectively:
transmission mode one may be used for V2X communication within the coverage of a base station. Taking dynamic scheduling as an example, the base station performs resource allocation in a centralized manner according to a Buffer Status Report (BSR) condition of the UE. Specifically, as shown in fig. 1, the base station may indicate a time-frequency resource of sidelink data of the sending end UE through Downlink Control Information (DCI), and the sending end UE receives the DCI and sends Sidelink Control Information (SCI) and the data to the receiving end UE on the time-frequency resource indicated by the DCI. In the first transmission mode, the sidelink transmission resources of each UE are uniformly scheduled by the base station, so that collision can be avoided.
The second transmission mode may refer to that the UE selects a time-frequency resource used for communication from available time-frequency resources included in the communication resource pool, and sends a control message and data on the selected time-frequency resource. In the second transmission mode, the sidelink transmission resource of the UE may be selected by the UE based on the result of self-interception, and the mode may not be limited to network coverage, and the sending UE may also communicate in this mode without network coverage.
2. Scheduling Request (SR) information and BSR information feedback
The UE may send SR information to the base station for informing a scheduler of the base station whether the UE has a scheduling request. In the following embodiments of the present application, for convenience of description, a UE presence scheduling request is referred to as a UE SR request, and a UE absence scheduling request is referred to as a UE SR-free request. For the UE with the 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. The SR information and the BSR information may be carried in a Physical Uplink Control Channel (PUCCH) and a Physical Uplink Shared Channel (PUSCH).
3. Hybrid automatic repeat request (HARQ) information
HARQ protocols exist at both the transmitting and receiving ends. HARQ operations of a transmitting end include transmitting and retransmitting Transport Blocks (TBs), receiving and processing Acknowledgement (ACK) information, and/or Negative Acknowledgement (NACK) information. The HARQ operation of the receiving end comprises receiving TB, soft combining processing, and generating and feeding back ACK/NACK information. After the sending end sends a TB, the receiving end receives the TB and performs Cyclic Redundancy Check (CRC) on the TB, if the CRC is successful, the receiving end feeds back ACK information to the sending end, and if the CRC fails, the receiving end feeds back NACK information. And if the sending end receives the NACK information, retransmitting the corresponding TB.
The ACK and/or NACK information is referred to herein as HARQ information.
4. PUCCH format
The PUCCH is used to transmit Uplink Control Information (UCI). The UCI may include one or more of HARQ information, SR information, link Recovery Request (LRR) and Channel State Information (CSI). The NR PUCCH has five formats, and occupied time domain and frequency domain resources and the number of information bits that can be carried are shown in table 1:
table 1 PUCCH format
Figure PCTCN2020086231-APPB-000001
Figure PCTCN2020086231-APPB-000002
The PUCCH format0 and the PUCCH format 1 adopt different sequences to feed back different information, and the PUCCH formats 2-4 adopt a mode of encoding UCI to feed back.
5. PUCCH format0
PUCCH format0 is a ZC sequence based on low peak-to-average ratio, and the specific generation mode is that a basic sequence r (n) is generated according to the sequence length, wherein n is more than or equal to 0<M ZC Performing phase rotation based on the base sequence r (n) to generate a reusable low peak-to-average ratio sequence, for example, the reusable low peak-to-average ratio sequence may be generated according to the following formula:
r α (n)＝r*e jαn ,0≤n<M ZC
for example, in the NR standard, PUCCH format0 sequence length is 12, i.e., M ZC =12, and PUCCH format0 supports transmission on one RB by multiple user code division multiplexing based on the sequence generated in the above manner. Since the UE needs to feed back ACK information and NACK information, that is, one user is allocated with at least two sequences, which correspond to different α values, respectively. The phase rotation value α can be determined by the following equation:
Figure PCTCN2020086231-APPB-000003
Figure PCTCN2020086231-APPB-000004
denotes the number of subcarriers in one RB, and NR defines this value as 12.

Indicating the slot number (slot number) corresponding to the current subcarrier spacing mu in a radio frame. For PUCCH format0,l ∈ {0,1}, l represents the symbol index of the sequence at the current PUCCH feedback resource. l' denotes a symbol index of the first symbol of the current PUCCH channel in the current slot. m is a unit of 0 Is configured by the network for each UE and represents the initial phase of the current user. Base station needs to be usedUsers configure different Sequence cyclic shift values (Sequence cyclic shift) m cs To express ACK information or NACK information in HARQ information and the existence of SR request, wherein, the sequence cycle shift value m cs They may be referred to as cyclic shift values, which are used interchangeably, and for convenience of description, they are referred to as cyclic shift values in the following embodiments.
m cs The configuration scheme can be shown in the following tables 2 to 5, where HARQ information in tables 2 and 3 is 1 bit, and table 2 is used to indicate that m corresponds to different HARQ information when the UE has no SR request cs . Table 3 is used to indicate m corresponding to different HARQ information when the UE has an SR request cs 。
The HARQ information in table 4 and table 5 is 2 bits, and table 4 is used to indicate m corresponding to different HARQ information when the UE has no SR request cs . Table 5 is used to indicate m corresponding to different HARQ information when the UE has an SR request cs 。
Wherein, the HARQ-ACK Value of 0 may be used to indicate that the HARQ information is NACK information, and the HARQ-ACK Value of 1 may be used to indicate that the HARQ information is ACK information.

According to the configuration parameters, the cyclic offset parameter α of one phase can be uniquely determined, and the PUCCH format0 sequence can be determined by the α. The specific calculation process may refer to fig. 2, that is, an m may be determined according to the HARQ information and/or the SR information cs And according to m configured by the higher layer 0 And (4) calculating the parameters to obtain a phase rotation factor, and generating transmission data, namely a PUCCH format0 sequence according to the generated base sequence.
Optionally, the HARQ information and the SR information may be transmitted separately using PUCCH format0, for example, in a non-SR reported slot, if the UE needs to feed back the HARQ information, the UE may transmit the HARQ information separately using PUCCH format0, in this scenario, the base station may configure table 2 or table 4 for the UE, and if table 2 is configured, it indicates that the base station expects the UE to feed back 1-bit HARQ information. If table 4 is configured, it indicates 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 that HARQ information does not need to be fed back, that is, the base station does not expect the UE to feed back the HARQ information, and may transmit the SR information by using PUCCH format0 alone. In this scenario, the base station may configure one sequence, i.e., m, for the UE cs Sequence represented by = 0. If the UE does not have the SR request, the UE may not report the SR information, i.e., does not send any signal of PUCCH format 0. If the UE has an SR request, the m can be sent cs PUCCH format0 sequence represented by = 0.
Optionally, the HARQ information and the SR information may also be bundled 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 desires the UE to feed back 1-bit HARQ information, the base station configures table 2 and table 3 for the UE. If the UE does not have the SR request, the UE selects the table 2 to feed back the HARQ information. If the UE has the SR request, the UE selects the table 3 to feed back the HARQ information.
If the base station desires the UE to feed back 2-bit HARQ information, the base station configures table 4 and table 5 for the UE. If the UE does not have the 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 may determine an m according to HARQ information and/or SR information cs According to m cs And generating a corresponding PUCCH format0 sequence and sending the PUCCH format0 sequence to the base station.
6. PUCCH format 1
The PUCCH format 1 still supports multi-user multiplexing on one same time-frequency resource, and the transmitted signal is further coded and modulated based on a ZC sequence with a low peak-to-average ratio. The number of the users supporting multiplexing on the same time frequency resource is the number of the time domain continuous symbols of the PUCCH except the pilot frequency
Figure PCTCN2020086231-APPB-000006
And (6) determining. Different from PUCCH format0, the ZC sequence of PUCCH format 1 does not carry any information, and the ZC sequences r of a plurality of users multiplexed on the same time-frequency resource α (n) are identical, and the specific process is shown in FIG. 3.
As shown in FIG. 3, the base station configures m for users multiplexed on the same time-frequency resource 0 Are identical, thereby generating identical ZC sequences r α (n), n denotes a subcarrier index. After bit information b (0) to be transmitted by each user is modulated, a modulation symbol d (0) is output, and the modulation mode comprises BPSK or QPSK. Where b (0) may be 1 bit or 2 bits. If b (0) is 1 bit, the modulation scheme is BPSK, and if b (0) is 2 bit, the modulation scheme is QPSK.
Further modulating d (0) onto the generated ZC sequence, i.e. with each r α (n) to produce y (n) = d (0) × r α (n)。
Generating an orthogonal spreading factor on the symbol m from the user i
Figure PCTCN2020086231-APPB-000007
Figure PCTCN2020086231-APPB-000008
And move w i (m) is multiplied by each y (n) to produce an output sequence z (m, n) = y (n) × w on each symbol i (m)。
Optionally, the HARQ information and the SR information may be transmitted separately using PUCCH format 1, for example, in a non-SR reported slot, if the UE needs to feed back the HARQ information, the UE may transmit the HARQ information separately using PUCCH format 1. In this scenario, if the HARQ information fed back by the UE is expected to be 1 bit by the base station, that is, the bit information b (0) to be transmitted is 1 bit, the bit information b (0) to be transmitted is modulated by using BPSK. If the HARQ information fed back by the UE is expected to be 2 bits by the base station, that is, the bit information b (0) to be transmitted is 2 bits, the bit information b (0) to be transmitted is modulated by QPSK.
For another example, in the timeslot reported by the SR, the UE does not receive data, so HARQ information does not need to be fed back, that is, the base station does not expect the UE to feed back the HARQ information, and may transmit the SR information by using PUCCH format 1 alone. In this scenario, if the UE has no SR request, the UE may not report SR information, that is, may not send any signal of PUCCH format 1. If the UE has an SR request, the bit information b (0) =0 to be transmitted, and the BPCK is used to modulate the bit information b (0) to be transmitted.
Optionally, the HARQ information and the SR information may also be bundled 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 the SR information and the 1-bit HARQ information may 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 feed back 2-bit HARQ information, the UE discards the SR information and transmits the 2-bit HARQ information using PUCCH format 1, where the bit information b (0) to be transmitted is 2 bits, and modulates the bit information b (0) to be transmitted using QPSK.
7. PUCCH format 2/3/4
PUCCH format 2/3/4 may carry one or more of HARQ information, SR information, link Recovery Request (LRR) and Channel State Information (CSI), etc. The control information to be transmitted (which may be referred to as bit information to be transmitted) may be transmitted by the encoding method shown in fig. 4. As shown in fig. 4, bit information to be transmitted is transmitted through channel coding, scrambling, modulation, and the like, wherein PUCCH format 2 and PUCCH format 4 support transform precoding shown by a dotted-line block, and PUCCH format 3 may not perform the transform precoding step. And after receiving the PUCCH reported information, the base station side obtains corresponding control information through decoding and analysis.
8、DRX
The generation of the data packets is not continuous, and when no data is transmitted, the power consumption can be reduced by turning off a receiving circuit of the UE, so that the service time of the mobile battery is prolonged. DRX techniques are introduced for power saving. The UE may be configured with several consecutive DRX cycles (DRX cycles). One DRX cycle defines the active time (active time), a set of several configurable different active periods that may contain the DRX On Duration (DRX On Duration), which may be indicated by the parameter DRX-onDurationTimer in NR systems. Several configurable different active periods contained in one DRX cycle may be consecutive or non-consecutive in time. In an active time period in one DRX period, the UE monitors and receives a PDCCH; and at other times except the active time period in the DRX period, the UE does not receive the data of the downlink channel so as to save power consumption.
The resource request information in this embodiment is used to request a sidelink transmission resource allocated On a first active time period in a DRX cycle, where the first active time period may be a DRX On Duration (DRX On Duration) in the DRX cycle, and it may be understood that the first active time period may also be other active time periods, which is not limited in this embodiment. Wherein the first activation period may include one or more activation periods.
Optionally, the resource request information may also be referred to as a DRX resource request, or a DRX on slot resource request, and the like, which is not limited in the embodiment of the present application.
In this embodiment, the network device expecting the terminal device to send the HARQ information may also be referred to as the network device having HARQ information feedback expectation, for example: the network device sends data to the terminal device, and accordingly, the terminal device has demodulation information of the received data, and 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 may also be referred to as network device no HARQ information feedback expectation, for example: the network device does not send data to the terminal device, and correspondingly, the terminal device does not receive the demodulation information of the data, so that the terminal device does not send HARQ information to the network device.
The present application may be applied to a first transmission mode of a sidelink data transmission scenario, and if a receiving UE (also referred to as a receiving terminal device or a receiving user) on a sidelink transmission (sidelink) link has an energy saving requirement, a DRX mechanism is introduced, that is, a DRX cycle is configured for the receiving UE. An originating UE (also referred to as a sending terminal device, or a sending user, etc.) on a sidelink transmission (sidelink) link requests a base station for a sidelink transmission resource corresponding to an active time period in a DRX cycle of a receiving UE before sending data to the receiving UE, so that the receiving UE can receive the data sent by the sending UE.
In a broadcast service scenario, the sending-end UE does not know what receiving UEs are before sending data, so that when the sending-end UE requests a base station to transmit resources laterally, the DRX cycle of the receiving UE cannot be determined, and the reliability of receiving all broadcast service data cannot be ensured.
To support the DRX mechanism of the broadcast service scenario, a uniform DRX cycle may be configured for all UEs with power saving requirements, for example, it is defined that all UEs with power saving requirements must receive information during the first active period of the DRX cycle. The first active period may be a DRX On period (DRX On Duration). In the present application, various ways are provided to facilitate the originating UE to request the base station to allocate sideline transmission resources in the first active time period in the DRX cycle, so as to ensure the reliability of receiving broadcast service data.
It can be understood that the present application may also be applied to a multicast service scenario, and the embodiments of the present application are not limited.
The technical scheme of the embodiment of the application 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 network networking, etc., and also can be used in other wireless networks, such as WiFi networks, long Term Evolution (LTE) networks, fifth generation (5g) networks, new wireless (NR) networks, device-to-device (D2D) networks, future networks, etc., and other new networks that appear along with the development of the technology.

In the description of the subsequent embodiments, when the network device receives the resource request information of the terminal device, it may be determined that the terminal device requests allocation of resources for sidelink transmission on the first active time period in the DRX cycle, and it may also be considered that the terminal device has a resource scheduling request.
In addition, the resource request information mentioned in the embodiments of the present application is used to request allocation of sidelink transmission resources on the first active time period in the DRX cycle.
Referring to fig. 6, a schematic flow chart of an information transmission method according to an embodiment of the present disclosure is shown, where the information transmission method according to the embodiment of the present disclosure includes, but is not limited to, the following steps:
s101, a terminal device determines control information, wherein the control information comprises resource request information, the resource request information is used for requesting a sidelink transmission resource allocated on a first active time period in a Discontinuous Reception (DRX) cycle, and the DRX cycle comprises at least one active time period.
In one embodiment, the control information may be UCI, and the resource request information is included in the control information. Optionally, the control information may include SR information and/or HARQ information in addition to the resource request information. The DRX cycle may include at least one active period, and the first active period in this embodiment may be one or more active periods in the at least one active period. Alternatively, the first active period may be a DRX On period (DRX On Duration) in the DRX cycle.
And S102, the terminal equipment sends the control information to the network equipment.
In one embodiment, the terminal device may transmit the control information to the network device through a PUCCH or a PUSCH. If the control information is transmitted to the network device through the PUCCH, the control information may be transmitted using one of PUCCH format0, PUCCH format 1, PUCCH format 2, PUCCH format 3, and PUCCH format 4, and the transmission of the control information using the PUCCH format will be described below. Optionally, the control information in this embodiment may be sent in a timeslot reported by the SR, where the timeslot reported by the SR may be understood as that the SR information may be sent periodically, that is, the timeslot reported by the SR information may be defined, and of course, the terminal device may send the SR information through the control information in the timeslot reported by the SR, or may not send the SR information, for example, if the terminal device does not need to send other information (the other information may be HARQ information, and may specifically refer to the description of the subsequent embodiment) in the timeslot reported by the SR, if the terminal device does not have a scheduling request, the terminal device may not send the SR information. Optionally, if the terminal device needs to send other information in the time slot reported by the SR, the SR information and the other information may be sent together in the time slot reported by the SR, where the SR information is used to indicate whether the terminal device has a scheduling request.
1. Transmitting control information using PUCCH format0
And the network equipment schedules the terminal equipment to transmit the control information by using PUCCH format 0. Since the PUCCH format0 represents different information in the control information through different sequences, and the different sequences are represented by different configured cyclic shift values m cs To be determined. Specifically, reference may be made to different cyclic shift values m in tables 2 to 5 in the foregoing embodiments cs Corresponding different information.
In an optional implementation manner, in a slot reported by an SR, when the control information includes resource request information, the first PUCCH format0 sequence and the second PUCCH format0 sequence may be sent, that is, the terminal device indicates the resource request information to the network device by sending the two PUCCH format0 sequences. Wherein the first PUCCH format0 sequence is obtained according to a first cyclic shift value, the second PUCCH format0 sequence is obtained according to a second cyclic shift value, and optionally, the first cyclic shift value and the second cyclic shift value may be values in a preconfigured cyclic shift value set. 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 include only 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 the HARQ information, the terminal device may determine the first cyclic shift value and the second cyclic shift value according to the HARQ information. Illustratively, 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 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 may be HARQ information that the terminal device prepares for feedback.
For example, in the SR reporting slot, if the HARQ information is 1 bit, that is, the network device expects the terminal device to transmit 1 bit HARQ information, the network device may configure table 2 and table 3 in the foregoing embodiment for the terminal device. Wherein the cyclic shift values contained in table 2 and table 3 may constitute a preconfigured set of cyclic shift values. The terminal equipment determines two cyclic shift values m from the table 2 and the table 3 respectively according to the first HARQ information of 1 bit to be fed back cs And the first cyclic shift value and the second cyclic shift value are respectively used as a first cyclic shift value and a second cyclic shift value, a first PUCCH format0 sequence is generated according to the first cyclic shift value, and a second PUCCH format0 sequence is generated according to the second cyclic shift value. The terminal equipment simultaneously sends the generated first PUCCH format0 sequence and second PUCCH format0 sequence to the network in the time slot reported by the SRAn apparatus. For example, if the first 1-bit HARQ information is ACK information, i.e. the HARQ-ACK Value is 1, the two cyclic shift values m cs May be 6 and 9, respectively; if the first 1-bit HARQ information is NACK information, i.e. the HARQ-ACK Value is 0, then two cyclic shift values m cs May be 0 and 3, respectively.
For example, in the timeslot 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. Wherein the cyclic shift values contained in table 4 and table 5 may constitute a preconfigured set of cyclic shift values. The terminal equipment determines two cyclic shift values m from the table 4 and the table 5 respectively according to the first HARQ information of 2 bits to be fed back cs And the first cyclic shift value and the second cyclic shift value are respectively used as a first cyclic shift value and a second cyclic shift value, a first PUCCH format0 sequence is generated according to the first cyclic shift value, and a second PUCCH format0 sequence is generated according to the second cyclic shift value. And the terminal equipment simultaneously transmits the generated first PUCCH format0 sequence and the second PUCCH format0 sequence to the network equipment in the time slot reported by the SR. For example, if the first 2-bit HARQ information is NACK information and NACK information, i.e. the HARQ-ACK Value is 00, the two cyclic shift values m cs May be 0 and 1, respectively; if the first 2-bit HARQ information is NACK information and ACK information, i.e. the HARQ-ACK Value is 01, then two cyclic shift values m cs There may be 3 and 4, respectively, and so on. The first HARQ information is NACK information and NACK information, which may indicate that HARQ information corresponding to two transport blocks is 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.
Accordingly, the network device may determine the resource request information, the SR information, and the first HARQ information included in the control information according to a first cyclic shift value corresponding to the first PUCCH format0 sequence and/or a second cyclic shift value corresponding to the second PUCCH format0 sequence, which is specifically referred to the description of the subsequent embodiments and will not be repeated here.
Optionally, in the timeslot reported by the SR, if the control information does not include HARQ information except the 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 cyclic shift value may correspond to the resource request information, where the first SR information indicates that the terminal device has a scheduling request. Alternatively, the second cyclic shift value may be different from the first cyclic shift value. Wherein, the first cyclic shift value may be 0, and a first PUCCH format0 sequence obtained according to the first cyclic shift value may be used to indicate that the terminal device has a scheduling request.
The second cyclic shift value may be a cyclic shift value of the new configuration corresponding to the resource request information, for example, the second cyclic shift value may be a cyclic shift value of the network device configuration. 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, a second PUCCH format0 sequence obtained according to the second cyclic shift value is also a newly configured sequence, and the second PUCCH format0 sequence may be used to indicate that the terminal device requests allocation of a sidelink transmission resource on the first active time period in the DRX cycle, that is, indicate that the control information includes resource request information.
For example, in a timeslot reported by the SR, if the control information does not include only HARQ information nor 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 requirement for uplink transmission resources in the first active time period in the DRX cycle, but the terminal device has an SR request, the terminal device may obtain a first PUCCH format0 sequence according to the first cyclic shift value, and send the first PUCCH format0 sequence to the network device in the timeslot reported by the SR, where the first cyclic shift value may be 0. Correspondingly, the network device may determine that the terminal device has the scheduling request according to the first cyclic shift value corresponding to the first PUCCH format0 sequence. It can be understood that, in this scenario, if there is no SR request by the terminal device, the terminal device may not transmit the 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 need for uplink transmission resources in the first active period in the DRX cycle, the terminal device generates a first PUCCH format0 sequence according to the first cyclic shift value and generates a second PUCCH format0 sequence according to the second cyclic shift value. And the terminal equipment simultaneously transmits the generated first PUCCH format0 sequence and the second PUCCH format0 sequence to the network equipment 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. Accordingly, the network device receives the two sequences, may determine that the control information includes the resource request information and the SR information, and specifically refer to the description of the subsequent embodiments, which is not repeated herein.
In another optional implementation, in the timeslot reported by the SR, the control information includes the resource request information, but does not include the HARQ information, that is, the network device does not expect the terminal device to send the HARQ information, and may send a third PUCCH format0 sequence, where the third PUCCH format0 sequence is obtained according to a 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 may be 0. 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, a third PUCCH format0 sequence obtained according to the third cyclic shift value is also a newly configured sequence, and the third PUCCH format0 sequence may be used to indicate that the terminal device requests allocation of a sidelink transmission resource on the first active time period in the DRX cycle, that is, indicate that the control information includes resource request information.
For example, in the SR reported slot, if the control information does not include HARQ information nor resource request information, that is, the network device does not expect the terminal device to send HARQ information, the terminal device does not have a requirement for uplink transmission resources in the first active time period in the DRX cycle, but the terminal device has an SR request, the terminal device may obtain a first PUCCH format0 sequence according to the first cyclic shift value, and send the first PUCCH format0 sequence to the network device in the SR reported slot, where the first cyclic shift value may be 0. Accordingly, 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 format0 sequence, but there is no need for uplink transmission resources in the first active time period in the DRX cycle.
If the control information does not include HARQ information but includes resource request information, i.e., the terminal device has a need for uplink transmission resources in the first active period in the DRX cycle, the terminal device may generate a third PUCCH format0 sequence according to the third cyclic shift value. And the terminal equipment sends the generated third PUCCH format0 sequence to the network equipment in the time slot reported by the SR. Accordingly, the network device may determine, according to a third cyclic shift value corresponding to the third PUCCH format0 sequence, that the terminal device has a requirement for uplink transmission resources in the first active time period in the DRX cycle, which may specifically refer to the description of the subsequent embodiment and is not described herein for further details.
2. Transmitting control information using PUCCH Format 1
The network device schedules the terminal device to transmit control information using PUCCH format 1, and the control information may be bit information to be transmitted. When the PUCCH format 1 is used to transmit the bit information to be transmitted, different modulation methods may be used when the number of the bit information to be transmitted is different, for example, if the number of the bit information to be transmitted is 1 bit, for example, the control information includes only SR information, the SR information indicates that the UE has an SR request, the value of the bit information to be transmitted is 0, and the bit information to be transmitted may be modulated by using BPSK. If the bit information to be transmitted is 2 bits, for example, the control information includes SR information and 1-bit HARQ information, the bit information to be transmitted may be modulated by using QPSK, which may specifically refer to the description of the foregoing embodiment and is not described herein again.
In an optional implementation manner, in a time slot reported by the SR, if the control information includes the resource request information but does not include the HARQ information, that is, the network device does not expect the terminal device to send the HARQ information, the terminal device may determine bit information to be transmitted according to the resource request information. 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.
Illustratively, in a time slot reported by an SR, if the control information includes SR information, and 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 requirement for uplink transmission resources in the first active time period in the DRX cycle, but the terminal device has an SR request, the terminal device determines, according to the SR information, that the value of the bit information to be transmitted is 0, and modulates the bit information to be transmitted by using BPSK. Further, the modulated bit information is transmitted using PUCCH format 1. Correspondingly, the network device decodes the received signal in PUCCH format 1, and the value of the obtained bit information is 0, it may be determined that the terminal device has an SR request, but there is no need for uplink transmission resources in the first active time period in the DRX cycle.
If the control information includes the resource request information and does not include the HARQ information, that is, the network device does not expect the terminal device to send the HARQ information, but the terminal device has a requirement for uplink transmission resources in the first active time period in the DRX cycle, the terminal device determines, according to the resource request information, that the value of the bit information to be transmitted is 1, and modulates the bit information to be transmitted by using BPSK. Further, the modulated bit information is transmitted using PUCCH format 1. It can be understood that, in this embodiment, by setting the value of the bit information to be transmitted to 1, it can indicate that not only the terminal device has an SR request, but also the terminal device has a need for uplink transmission resources in the first active time period in the DRX cycle. Accordingly, the network device decodes the received signal in PUCCH format 1, and obtains a value of bit information of 1, and may determine that the control information includes resource request information, that is, determine that the terminal device has a requirement for uplink transmission resources in the first active time period in the DRX cycle, which may specifically refer to the description of the subsequent embodiments and is not repeated here.
In another optional implementation, in a time slot reported by the 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 requirement for uplink transmission resources in the first active time period in the DRX cycle, the terminal device determines bit information to be transmitted according to the 1-bit HARQ information, SR information, and resource request information. The terminal device further adopts pi/4 QPSK to modulate HARQ information and SR information in bit information to be transmitted, and uses PUCCH format 1 to send modulated bit information to the network device in a time slot reported by the SR. Namely, the terminal device indicates the resource request information to the network device through the difference of the modulation modes. Correspondingly, when the bit information to be transmitted does not include the resource request information, and only includes 1-bit HARQ information and SR information, the terminal device modulates the HARQ information and the SR information by using QPSK.
Exemplarily, in a timeslot reported by an SR, if the control information includes SR information and 1-bit HARQ information, and 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 requirement for uplink transmission resources in the first active time period in the DRX cycle, the terminal device determines bit information to be transmitted according to the 1-bit HARQ information and the SR information, and modulates the bit information to be transmitted by using QPSK. Further, the terminal device transmits the modulated bit information to the network device using PUCCH format 1. Accordingly, after the network device receives the signal of PUCCH format 1, if it is detected that the signal of PUCCH format 1 is based on QPSK modulation, it may be determined that the resource request information is not included in the control information.
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 requirement for uplink transmission resources in the first active time period in the DRX cycle, the terminal device determines bit information to be transmitted according to the 1-bit HARQ information, SR information, and resource request information, modulates the HARQ information and SR information in the bit information to be transmitted by using pi/4 quadrature phase shift keying QPSK, and sends the modulated bit information to the network device by using PUCCH format 1. Correspondingly, in the timeslot reported by the SR, after the network device receives the signal in PUCCH format 1, if it is detected that the signal in PUCCH format 1 is modulated based on pi/4 QPSK, it may be determined that the control information includes resource request information, that is, it is determined that the terminal device has a requirement for uplink transmission resources in the first active time period in the DRX cycle, which is specifically described with reference to the following embodiments, and is not repeated here.
In yet another optional implementation manner, in a time slot reported by the 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 requirement for uplink transmission resources in the first active time period in the DRX cycle, the terminal device determines 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 by using 16 QAM. The terminal device further transmits the modulated bit information to the network device using PUCCH format 1. In this embodiment, since 16QAM can implement modulation on 4-bit information, in this embodiment of the present application, 16QAM may be used to modulate all bit information in the bit information to be transmitted.
Illustratively, in a timeslot reported by an 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 requirement for uplink transmission resources in a first active time period in a DRX cycle, the terminal device determines bit information to be transmitted according to the 2-bit HARQ information, the SR information, and the resource request information, modulates the bit information to be transmitted by using 16QAM, and sends the modulated bit information to the network device by using PUCCH format 1. Correspondingly, in the time slot reported by the 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. That is, it may be determined that the terminal device has a requirement for uplink transmission resources in the first active time period in the DRX cycle, and for details, refer to the description of the subsequent embodiments, which is not repeated herein.
Optionally, the sending of the modulated bit information to the network device by using the PUCCH format 1 described in the foregoing 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, which please refer to the description of the foregoing embodiment in fig. 3, which is not described herein again.
3. Transmitting control information using one of PUCCH Format 2, PUCCH Format 3, and PUCCH Format 4
And the network equipment schedules the terminal equipment to transmit the control information by using one of PUCCH format 2, PUCCH format 3 and PUCCH format 4, so that the terminal equipment can encode the control information containing the resource request information and transmit the encoded control information to the network equipment by using one of PUCCH format 2, PUCCH format 3 and PUCCH format 4.
Optionally, one of the PUCCH formats 2, 3, and 4 is used to send the encoded control information to the network device, where the terminal device may perform channel coding on the control information, and further perform other operations such as scrambling and modulating on the control information after channel coding, and please refer to the description of the embodiment in fig. 4 specifically, which is not described herein again.
The control information may be bit information to be transmitted, and the bit information to be transmitted may be UCI. Specifically, optionally, 1-bit information may be added to the UCI to indicate the resource request information, so as to indicate that the terminal device has a requirement of uplink transmission resource in the first active time period in the DRX cycle.
Exemplarily, as shown in the schematic diagram of UCI shown in table 6, 1-bit information (i.e. DRX resource request) is added at the end of the UCI for indicating the resource request information. The encoding method of the resource request information may be the same as the encoding method of the SR information.
Table 6 UCI schematic diagram
Figure PCTCN2020086231-APPB-000009
S103, the network equipment receives control information, wherein the control information comprises resource request information, the resource request information is used for requesting to allocate sidelink transmission resources on a first active time period in a Discontinuous Reception (DRX) cycle, and the DRX cycle comprises at least one active time period.
In one embodiment, the terminal device transmits the control information to the network device through a PUCCH or a PUSCH, and accordingly, the network device receives the control information through the PUCCH or the PUSCH. If the control information is sent to the network device through the PUCCH, the network device may schedule the terminal device to send the control information to the network device using one of PUCCH formats 0,1, 2, 3, and 4, and accordingly, the network device receives a signal of the corresponding PUCCH format and determines information included in the control information according to the received signal of the PUCCH format. The following are set forth separately:
1. network equipment scheduling terminal equipment uses PUCCH format0 to send control information
In an optional implementation manner, in a timeslot reported by the SR, if the terminal device sends the first PUCCH format0 sequence and the second PUCCH format0 sequence, that is, the terminal device indicates the resource request information to the network device by sending the two PUCCH format0 sequences. Correspondingly, the network device receives the first PUCCH format0 sequence and the second PUCCH format0 sequence, and may determine that the control information includes resource request information, that is, determine that the terminal device has a requirement for uplink transmission resources in the first active period in the DRX cycle.
Optionally, in the timeslot reported by the SR, if the network device further expects the terminal device to send HARQ information, that is, the network device expects that the control information includes HARQ information in addition to the resource request information, the network device may further obtain a first cyclic shift value corresponding to the first PUCCH format0 sequence and a second cyclic shift value corresponding to the second PUCCH format0 sequence, and determine the first HARQ information included in the control information according to the first cyclic shift value and/or the second cyclic shift value.
For example, in the timeslot reported by the SR, if the network device expects the terminal device to transmit 1-bit HARQ information, the network device may 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 and second cyclic shift values are 6 and 9, respectively, it may be determined that the first HARQ information is 1, i.e., ACK information.
For example, in the timeslot reported by the SR, if the network device expects the terminal device to transmit 2-bit HARQ information, the network device may 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 may be determined that the first HARQ information is NACK information and ACK information, i.e., the first transport block corresponds to NACK information and the second transport block corresponds to ACK information.
Optionally, in the timeslot reported by the SR, 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 may determine that the terminal device has an SR request according to the received first PUCCH format0 sequence and the received second PUCCH format0 sequence, and the terminal device requests to allocate a sidelink transmission resource on the first active time period in the DRX cycle. It is to be understood that the network device may further obtain a first cyclic shift value corresponding to the first PUCCH format0 sequence and a second cyclic shift value corresponding to the second PUCCH format0 sequence, and if the first cyclic shift value corresponds to the first SR information, the second cyclic shift value may correspond to the resource request information, determine that the terminal device has an SR request, and that the terminal device has a requirement for a downlink transmission resource in the first active time period in the DRX cycle, where the first SR information indicates that the terminal device has a scheduling request. In this embodiment, 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 is not described herein again.
For example, in a timeslot reported by an SR, if the network device does not expect the terminal device to send HARQ information, if the network device only receives a first PUCCH format0 sequence, and the first PUCCH format0 sequence corresponds to a first cyclic shift value, and the first cyclic shift value corresponds to a first SR request, for example, the first cyclic shift value is 0, it may be determined that the control information includes SR information, and 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 format0 sequence and the second PUCCH format0 sequence, it may be determined that the control information includes resource request information, that is, it is determined that the terminal device has a requirement for uplink transmission resources in the first active period in the DRX cycle.
In another optional implementation manner, in the timeslot reported by the SR, the network device does not expect the terminal device to send HARQ information, the network device receives a third PUCCH format0 sequence, and further obtains a third cyclic shift value corresponding to the third PUCCH format0 sequence, and if the third cyclic shift value is a cyclic shift value corresponding to the resource request information, it may be determined that the control information includes the resource request information, that is, it may be determined that the terminal device has a requirement for uplink transmission resources in the first active time period in the DRX cycle. For the description of the third cyclic shift value, please refer to the description of the terminal device side, which is not described herein again.
2. Network equipment scheduling terminal equipment to transmit control information by using PUCCH format 1
The control information may be bit information, i.e. the network device receives the bit information. Specifically, optionally, the network device may decode the signal in PUCCH format 1, so as to obtain the bit information. For example, the terminal device sends the control information in the timeslot reported by the SR, and accordingly, the network device may receive the control information in the timeslot reported by the SR.
In an optional implementation manner, in a timeslot reported by the SR, if the network device does not expect the terminal device to send HARQ information, the network device determines that the terminal device modulates bit information by using BPSK, and correspondingly, after receiving a signal in PUCCH format 1, the network device decodes the signal in PUCCH format 1 based on BPSK to obtain bit information, and if the value of the bit information is 1, determines that the control information includes resource request information, that is, determines that the terminal device has a need for uplink transmission resources in a first active time period in a DRX cycle. If the value of the bit information is 0, it is determined that the control information only includes SR information and does not include resource request information, that is, it is determined that the terminal device only has an SR request and does not have a need for uplink transmission resources in the first active period in the DRX cycle.
In another optional implementation manner, in a time slot reported by the SR, the network device expects the terminal device to send 1-bit HARQ information, that is, bit information includes 1-bit HARQ information, and in order to further determine whether the bit information includes resource request information, after receiving a signal in PUCCH format 1, the network device may further detect a modulation mode of the signal in PUCCH format 1. If the PUCCH format 1 signal is pi/4 QPSK modulated, the bit information includes resource request information. Further, the network device decodes the signal of the PUCCH format 1 based on pi/4 QPSK, thereby further obtaining 1-bit 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 signal in PUCCH format 1 based on QPSK, thereby obtaining 1-bit HARQ information and SR information in the bit information.
In yet another optional implementation, in a timeslot reported by the SR, the network device expects the terminal device to send 2-bit HARQ information, that is, the bit information includes 2-bit HARQ information, the network device may determine that the terminal device adopts 16QAM to modulate the bit information, and correspondingly, after receiving a signal in PUCCH format 1, the network device decodes the signal in PUCCH format 1 based on 16QAM, thereby obtaining the bit information. Wherein the bit information includes resource request information, SR information, and 2-bit HARQ information.
3. Network equipment scheduling terminal equipment sends control information by using one of PUCCH format 2, PUCCH format 3 and PUCCH format 4
If the terminal device uses PUCCH format 2 to send the encoded control information to the network device, the network device decodes the PUCCH format 2 signal accordingly to obtain the control information. If the terminal device uses the PUCCH format 3 to send the encoded control information to the network device, the network device correspondingly decodes the signal in the PUCCH format 3 to obtain the control information. If the terminal device uses the PUCCH format 4 to send the encoded control information to the network device, the network device correspondingly decodes the signal in the PUCCH format 4 to obtain the control information.
Optionally, before performing decoding, the network device may further perform operations such as descrambling and demodulating the signal in PUCCH format 2 or the signal in PUCCH format 3 or the signal in PUCCH format 4.
And S104, the network equipment configures the sideline transmission resources on the first activation time period for the terminal equipment according to the resource request information.
In one embodiment, when the network device determines that the control information includes the resource request information, the terminal device may be configured with the sidelink transmission resource over the first active time period. Further, the network device sends resource scheduling information to the terminal device, where the resource scheduling information is used to indicate the configured sidelink transmission resource on the first active time period to the terminal device. For example, the resource scheduling information may include time-frequency resource information of sidelink transmission resources configured by the network device.
Accordingly, the terminal device receives the resource scheduling information and transmits the broadcast information or the multicast information on the indicated sideline transmission resource.
Since the terminal device with the energy saving requirement configures a uniform DRX cycle and the terminal device with the energy saving requirement must receive information in the first active time period of the DRX cycle, the terminal device transmits the broadcast information on the sideline transmission resource of the first active 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 a terminal device with an energy saving requirement and a terminal device without an energy saving requirement.
It can be understood that, if the terminal device sends the multicast information on the sidelink transmission resource of the first active time period, a uniform DRX cycle may be configured for the terminal device having the energy saving requirement in the packet, and the terminal device configured with the uniform DRX cycle must receive the information in the first active time period, thereby improving the reliability of receiving the multicast information.
