Description

Terminal, network device and uplink control information processing method

The present invention relates to the field of wireless communication technologies, and in particular, to a terminal, a network device, and an uplink control information processing method.

Background technique

In a wireless communication system, a user equipment (UE) needs to feed back uplink control information (UCI, Uplink Control Information) to a base station, including information for indicating a downlink channel state, information indicating a downlink data reception status, and uplink. Data scheduling request, etc. In the Long Term Evolution (Advanced-Advanced) (LTE-A) system, the UCI can be carried on the physical uplink control channel (PUCCH) or on the physical uplink shared channel (Physical Uplink Shared CHannel). , PUSCH), multiplexed with the uplink service data for transmission.

In the LTE-A system, Carrier Aggregation (CA) technology is adopted, which combines the spectrums of two or more Component Carriers to obtain a wider transmission bandwidth.

For carrier aggregation between base stations, that is, carrier aggregation in the case of Dual Connectivity (DC), non-ideal backhaul between base stations is impossible to transmit data in real time.

Since the base stations are non-ideal backhaul, the different base stations participating in the carrier aggregation independently schedule the UEs, and it is difficult for the base stations to coordinate the scheduling of the UEs in real time, so that the uplink transmission power of the UEs required by the total scheduling result of all the serving cells to the UE may exceed the UE. Maximum uplink transmit power. At present, a processing method of the UE is: preferentially performing allocation of PUCCH transmission power, performing transmission power allocation of the PUSCH carrying the UCI, and finally performing transmission power allocation of the PUSCH not including the UCI. For multiple uplink physical channels with the same transmit power allocation priority, if the required transmit power exceeds the maximum transmit power of the UE, Power Scaling is performed, that is, the transmit power is scaled down. The processing method may cause: the UE preferentially allocates work for the PUCCH. After the rate, the power allocated to the PUSCH containing the UCI is limited. If the data volume of the service data transmitted in the PUSCH is much larger than the data volume of the UCI on the PUSCH, the limited power is mostly allocated to the service data carried on the PUSCH. The power used to transmit the UCI is insufficient, which may cause the base station to fail to correctly receive the UCI on the PUSCH.

In summary, for the uplink physical channel that includes the uplink control information, if the amount of service data carried on the uplink physical channel is much larger than the data amount of the uplink control information, the power of the terminal for transmitting the uplink control information may be insufficient.

Hereinafter, the concept related to the embodiment of the present invention will be briefly introduced.

First, the uplink control information

In a wireless communication system, a terminal usually sends uplink control information to a network device, and feeds back a downlink channel state, a downlink data reception situation, and an uplink data scheduling request. This information may include but is not limited to:

Feedback information for downlink data reception feedback, such as: Long Term Evolution (LTE) or ACKnowledgement (ACK)/Negative ACKnowledgement (NACK) information in LTE-A system, used for feedback Whether the transport block of the downlink data channel is correctly received at the terminal, and ACK and NACK are collectively referred to as Hybrid Automatic Repeat Request (HARQ)-ACK;

The indication information for indicating the status of the downlink channel, for example, the channel state information (CSI) in the LTE or LTE-A system, according to the manner of CSI transmission, may be divided into periodic CSI (sent by a certain period) and The aperiodic CSI can be classified into a channel quality indicator (Channel Quality Indicator), a Rank Indicator (RI), and a Precoding Matrix Indicator (PMI) according to the CSI content.

Information for requesting uplink data scheduling, such as: Scheduling Request (SR) in LTE or LTE-A system.

In the existing LTE-A system, when the carrier aggregation technology is used, the Physical Uplink Control CHannel (PUCCH) channel carrying the uplink control information (for example, HARQ-ACK) is transmitted only on the primary carrier. If the UE does not support the PUCCH and the Physical Uplink Shared CHannel (PUSCH), and the uplink carrier of the UE If the PUSCH needs to be sent, all the uplink control information may be sent on the PUSCH. If the UE supports the PUCCH and the PUSCH channel, and the PUSCH needs to be sent on the uplink carrier of the UE, the uplink control information is used. The HARQ-ACK is transmitted on the PUCCH, and the CSI in the UCI is transmitted on the PUSCH. In any case, only one uplink physical channel carries HARQ-ACK information, and the uplink physical channel may be a PUCCH or a PUSCH. Similarly, only one uplink physical channel carries CSI information, and the uplink physical channel may be a PUCCH or a PUSCH.

Although the LTE and LTE-A systems are taken as an example to introduce the above uplink control information, those skilled in the art should be aware that in other wireless communication systems, such as a High Speed Downlink Packet Access (HSDPA) system. The ACK/NACK transmitted on the High Speed-Shared Information Channel (HS-SICH) is also a kind of feedback information for receiving downlink data, and the CQI is also an indication information for indicating the status of the downlink channel. In the High Speed Uplink Packet Access (HSUPA) system, the information transmitted on the Enhanced-Random Access Uplink Control Channel (E-RUCCH) is also used. Information requesting uplink data scheduling. Therefore, the uplink control information in the embodiment of the present invention is not limited to the uplink control information in the LTE or LTE-A system.

In the LTE or LTE-A system, the uplink control information may be carried on a Physical Uplink Control CHannel (PUCCH), or may be carried on a Physical Uplink Shared CHannel (PUSCH), and the PUSCH. The business data on it is transmitted together. The service data on the PUSCH includes control signaling of an upper layer transmission.

A collection of multiple cells for data transmission simultaneously with a terminal under a base station or a base station controller.

In an LTE or LTE-A system, there may be multiple PUSCH channels used by one terminal for uplink data transmission in one cell group, but there is only one PUCCH channel for the terminal.

4. Macro cell group (MCG) and small cell group (SCG)

The macro cell group refers to a set of multiple cells that are communicated with the terminal under the macro base station, and the small cell group refers to a set of multiple cells under the base station to which the small cell belongs and the terminal communicates.

V. Uplink demodulation reference signal

A reference signal used in uplink demodulation, which is related to transmission of the first uplink physical channel and the second uplink physical channel. For example: DeModulation Reference Signal (DMRS) in LTE or LTE-A systems.

Next, the wireless communication system to which the embodiment of the present invention is applied, the meaning of the partial expression mode in the embodiment of the present invention, and the like are briefly described.

The allocation may cause the problem that the total uplink scheduling result of the terminal exceeds the uplink service data transmission capability of the terminal:

The second generation (2 ^nd Generation, 2G) mobile communication system, wherein, 2G mobile communication systems include, but are not limited to: the GSM (Global System of Mobile communication, GSM ), CDMA (Code Division Multiple Access, CDMA IS-95, Code Division Multiple Access (CDMA) 2000, etc.; 3G mobile communication system, where 3G mobile communication system includes but not limited to: Time Division-Synchronous Code Division Multiple Access, TD-SCDMA), Wideband Code Division Multiple Access (WCDMA), etc.; 4G mobile communication system, where 4G mobile communication systems include but are not limited to: Time Division Duplex - Long Term Evolution (Time Division) Duplexing-Long Term Evolution (TDD LTE), Frequency Division Duplexing-Long Term Evolution (FDD LTE), Long Term Evolution-Advanced (LTE-A), and the like.

Hereinafter, embodiments of the present invention will be described in detail with reference to the accompanying drawings. First, the implementation of the present invention will be described. The wireless communication system provided by the example is introduced to the two terminals and the two network devices provided by the embodiments of the present invention. Finally, the two uplink control information processing methods provided by the embodiments of the present invention are introduced.

FIG. 1 is a schematic structural diagram of a wireless communication system according to an embodiment of the present invention. As shown in FIG. 1, the system includes: a terminal 101 and one or more network devices 102 for performing data transmission with the terminal 101, wherein:

The network device 102 is configured to wait for the first uplink physical channel sent by the receiving terminal 101 in a predetermined subframe after the scheduling terminal 101 performs uplink service data transmission;

The terminal 101 is configured to: when the uplink control information is included in the first uplink physical channel that the network device 102 is waiting to receive, in the scheduling of the network device 102, at least part of the uplink control information is used by the second uplink Physical channel transmission, where the second uplink physical channel and the first uplink physical channel belong to the same cell group under the control of the network device 102;

The network device 102 is further configured to detect, on the second uplink physical channel, uplink control information that is expected to be sent on the first uplink physical channel.

In FIG. 1, the connection between the terminal 101 and the network device 102 is a solid line, which indicates that data is transmitted between the terminal 101 and each network device 102, and does not represent a wired connection between the terminal 101 and the network device 102. .

Optionally, the network device 102 schedules the terminal 101 by sending uplink service scheduling indication information and/or uplink service data transmission response information.

For example, for the LTE or LTE-A system, the uplink service scheduling indication information may be sent through the PDCCH or the Enhanced Physical Downlink Control CHannel (EPDCCH); the uplink service data transmission response information may be automatically retransmitted through the physical hybrid indication. The Physical Hybrid ARQ Indicator Channel (PHICH) is transmitted.

If the terminal 101 detects that the network device 102 sends an uplink scheduling indication to the terminal in the PDCCH/EPDCCH channel, whether the uplink service data transmission response information indication in the PHICH channel is detected, the terminal detects the PDCCH/EPDCCH channel. Sending uplink data to the uplink scheduling indication of the terminal;

If the terminal 101 does not detect that the network device 102 is transmitting in the PDCCH/EPDCCH channel If the uplink service data transmission response information indication in the PHICH channel is detected, if the terminal 101 detects that the uplink service data transmission response information indication information sent in the PHICH channel is NACK, the terminal 101 follows the previous time. The uplink resource of the HARQ process transmitted at the current time is retransmitted, and the data of the current HARQ process is retransmitted. If the terminal 101 detects that the uplink service data transmission response information indication information sent in the PHICH channel is an ACK, the terminal 101 does not need to send the uplink data.

In the following, the FDD LTE system is taken as an example to illustrate a method in which the network device 102 expects to have uplink control information on the first uplink physical channel.

In the FDD LTE system, the network device 102 transmits downlink data to the terminal 101 through the PDCCH/EPDCCH scheduling in the subframe n, and the network device 102 expects the terminal 101 to transmit the HARQ of the downlink data scheduled for the subframe n in the subframe n+4. -ACK information.

The network device 102 schedules transmission of uplink initial transmission or retransmission data to the terminal 101 through the PDCCH/EPDCCH and/or PHICH channel scheduling in the subframe n, or instructs the terminal 101 to transmit aperiodic CSI information. The network device 102 then expects the terminal 101 to transmit uplink data or aperiodic CSI information in the subframe n+4 in accordance with the scheduling of the subframe n.

The network device 102 configures the period of the feedback period CSI, the subframe offset, and the like for the terminal 101. The terminal 101 can determine the time of the feedback period CSI according to the configuration information of the network device 102, and the network device 102 can determine the configuration information according to the configuration information. The time at which the terminal 101 periodic CSI information is expected to be received. If the terminal 101 needs to feed back the periodic CSI and the feedback non-periodic CSI at the same time, only the aperiodic CSI is fed back, and the network device 102 can also perform the scheduling request for the aperiodic CSI of the terminal 101 and the feedback timing of the feedback of the aperiodic CSI. The relationship and the configuration indication of the terminal 101 periodic CSI determine whether the terminal 101 feeds back a periodic CSI or a non-periodic CSI.

Optionally, the terminal 101 may determine at least a part of the uplink control information included in the first uplink physical channel, where the following situation occurs, where the second uplink physical channel is sent:

The terminal 101 transmits the uplink control information in the uplink physical channel with the uplink control information, because the sum of the transmit powers of the uplink physical channels to be transmitted is greater than the maximum uplink transmit power of the uplink physical channel. The rate is reduced.

For the first case, as long as the power of the uplink control information in the uplink physical channel including the uplink control information is reduced, at least a part of the uplink control information in the first uplink physical channel is placed in the cell group to which the first uplink physical channel belongs. The terminal 101 transmits in the second uplink physical channel. Here, the uplink physical channel including the uplink control information may be the first uplink physical channel or the second uplink physical channel.

Case 2

The terminal 101 reduces the power of the uplink control information in the uplink physical channel including the uplink control information to one or more of the following conditions, because the sum of the transmit powers of the uplink physical channels to be transmitted is greater than its maximum uplink transmit power. :

The reduced power is less than the first power threshold;

Similarly, in case two, the uplink physical channel including the uplink control information may be the first uplink physical channel or the second uplink physical channel.

In the above judgment conditions, "less than" can be replaced by "less than or equal to", and either "less than" or "less than or equal to" should be considered as being within the scope of protection of the present application.

The LTE-A system is used as an example to describe the possible cases where the sum of the transmit powers of the uplink physical channels to be transmitted is greater than the maximum uplink transmit power of the uplink.

Possible situation one

The terminal 101 transmits the PUCCH and the PUSCH1 in the cell 1 or the CG1, where the PUSCH1 includes the uplink control information, and the sum of the transmit powers of the PUCCH and the PUSCH1 is greater than the maximum uplink transmit power of the terminal 101;

For a specific embodiment of the case-by-case process, reference may be made to the following embodiment 1.

Possible situation two

The terminal 101 transmits a PUCCH at CG1, and transmits PUSCH1 at CG2, where PUSCH1 Including uplink control information, the sum of the transmit powers of the PUCCH and the PUSCHI is greater than the maximum uplink transmit power of the terminal 101;

For the specific embodiment of the possible case two processing, refer to the following second embodiment, the third embodiment, the fourth embodiment and the fifth embodiment.

For the possible case 2, the LTE-A system is taken as an example to specify that the sum of the transmit powers of the PUCCH and the PUSCH1 is greater than the maximum uplink transmit power of the terminal 101, and the uplink power is reduced, so that the receiving performance of the uplink control information in the PUSCH1 cannot be satisfied. Claim.

It is assumed that the PUQCH sent by the CG1 includes the HARQ-ACK2 information sent by the terminal to the network device, and the PUSCH1 sent by the CG2 includes the HARQ-ACK1 information sent by the terminal to another network device. The network device corresponding to CG2 is allocated by the terminal to the PUSCH1 carrying the HARQ-ACK1

The PRB number is NPRB, and the transmit power is PPUSCH. The X% resource of the NPRB resource of the PUSCH1 is used to transmit HARQ-ACK1, and the 1-X% resource is used to transmit the uplink UL-SCH, and HARQ-ACK1 and UL- The transmit power of the SCH data on one RE (Resource Element Resource Element) in PUSCH1 is equal, Ppusemz N^P HARQ-AOO_RE+N ₂ *P _UL-SC H RE, where PUSCH1 is used to transmit HARQ The number of REs of ACK1, and N ₂ is the number of REs used to transmit UL-SCH data in PUSCH1. P _ACK i — RE=PUL-SCH — RE is the transmit power of each RE in PUSCH1.

It is assumed that the transmission power of the PUCCH carrying HARQ-ACK2 is P _PUCCH , PpuscHi+PpuccH>Pcmax (Pcmax is the maximum uplink transmission power of the terminal 101), wherein if the PPUSCHI and P _PUCCH are proportionally compressed, w*(P _PU scHi +PPUCCH ) < Pcmax, ie W* (Ni *P HARQ-ACKl_RE+N2*PuL-SCH_RE +PPUCCH ) Pcmax. Finally, the transmission power used to transmit the HARQ-ACK1 in PUSCH1 is Λ^Ν Ρ HARQ-ACKI RE, that is, the transmission power of each RE used by PUSCH1 to transmit HARQ-ACK1 is compressed into w*P HARQ-ACKI-RE The transmit power of PUCCH is reduced to w*P _PUCCH . Thus, if N ₂ is very large, that is, UL-SCH occupies more PRBs, it needs to be very small to satisfy the requirement of w* ( PPUSCHI + PPUCCH ) < Pcmax, that is, the transmit power used to transmit HARQ-ACK1 in PUSCH1 and The transmit power used to transmit the PUCCH is very small. Thus affecting HARQ-ACK1 and HARQ-ACK2 each in eNBl and The receiving performance of eNB2 ultimately affects the data transmission efficiency of the system.

Alternatively, if the performance of the HARQ-ACK2 is guaranteed, the power compression of the Pp _USCm is first such that W*PpusCH1 + PPUCCH < PcmaX, that is, W* (Ni * P HARQ - ACK1_RE + N ₂ * PuL - SCH_RE ) + PpUCCH Pcmax. The transmission power used to transmit the HARQ-ACK1 in PUSCH1 is finally w*N^P HARQ-ACKi_RE, that is, the transmission power of each RE used by PUSCH1 to transmit HARQ-ACK1 is compressed into WP HARQHO_RE. Thus, if N ₂ is very large, that is, UL-SCH occupies more PRBs, it needs to be very small to meet the requirements of w*Pp _USCm +PpuccH < Pcmax. That is, the transmission power used to transmit HARQ-ACK1 in PUSCH1 is small. Therefore, the reception performance of HARQ-ACK2 in eNB2 is affected, which ultimately affects the data transmission efficiency of the system.

Alternatively, if the performance of the HARQ-ACK1 is guaranteed, the power compression of the Pp _UCC H is first such that PPUSCHI + W*PpucCH < PcmaX, that is, Ni*P HARQ-ACK1_RE+N ₂ *PuL-SCH_RE+W*PpucCH Pcmax. The transmission power used to transmit HARQ-ACK2 in PUSCH1 is finally w*Pp _UCCH , that is, the transmission power of PUCCH is compressed into w*Pp _UCCH . Thus, if N ₂ is very large, that is, UL-SCH occupies more PRB, it needs to be very small to meet the PPUSCHI + W*P _PUC CH Pcmax requirement. That is, the power used to transmit PUCCH is small. Thereby affecting the reception performance of HARQ-ACK1 in eNB1, and ultimately affecting the data transmission efficiency of the system.

Optionally, the terminal 101 determines that the HARQ-ACK information used to indicate the downlink data reception status and/or the periodic indication information used to indicate the downlink channel status in the uplink control information included in the foregoing first uplink physical channel is passed. The second uplink physical channel is sent.

Optionally, if the terminal 101 does not support the first uplink physical channel and the second uplink physical channel to transmit together, the terminal 101 determines to abandon sending the first uplink physical channel.

If the terminal 101 supports the first uplink physical channel and the second uplink physical channel to be transmitted together, the terminal 101 determines to use the uplink control information included in the first uplink physical channel. The periodic indication information indicating the downlink channel state is sent by using the second uplink physical channel, and the terminal 101 determines that the first uplink physical channel is still sent.

Optionally, the terminal 101 determines that the first uplink physical channel is still sent on the first uplink physical channel. The periodic indication information used to indicate the status of the downlink channel in the uplink control information included in the uplink control information.

For the LTE or LTE-A system, the eNB can configure whether to support PUSCH and PUCCH transmission by the eNB through the parameter "simultaneous PUCCH-PUSCH" (PUCCH and PUSCH transmission) according to the existing 3GPP TS 36.331.

Correspondingly, if the terminal 101 determines that the first uplink physical channel is still sent, and determines that the period of the downlink channel state in the uplink control information included in the first uplink physical channel is still sent on the first uplink physical channel, Sexual indication information, then

The network device 102 can detect the period of the downlink channel state according to the second uplink physical channel used by the terminal 101 from the first uplink physical channel and the cell group to which the first uplink physical channel belongs. The sexual indication information determines the periodic indication information sent by the terminal 101 for indicating the status of the downlink channel. Thus, the network device 102 may obtain a diversity reception gain and improve the reception quality of the uplink control information.

Optionally, the network device 102 can determine whether the terminal 101 abandons sending the first uplink physical channel by:

The network device 102 determines whether the terminal 101 abandons the transmission of the first uplink physical channel according to whether the uplink demodulation reference signal corresponding to the first uplink physical channel is received.

In the LTE system or the LTE-A system, each transport block sent by the UE corresponds to one codeword. The signals of each codeword are mapped to their respective layers before being precoded (Precoding). When the PUSCH channel transmission is specified in 5.5.2.1 of the 3GPP Technical Specification TS 36.211, the layer, ^{A e} {G, l, ..., ! - 1} Corresponding _DMRS signal generation method and resource mapping method. If the UE abandons all or part of the transport block of the PUSCH, the DMRS signal corresponding to the codeword corresponding to each transport block is discarded. In summary, in the embodiment of the present invention, when the terminal 101 abandons the transmission of the transport block, the uplink demodulation reference signal corresponding to the transport block may be discarded at the same time.

In the embodiment of the present invention, when determining whether the terminal 101 abandons the first uplink physical channel, the network device 102 may use multiple methods including the following two methods:

method one If the network device 102 determines that the terminal 101 abandons transmitting a transport block on the first uplink physical channel in a certain subframe, the network device 102 determines that the terminal 101 abandons sending the first uplink physical channel in the subframe; if the network device 102 determines the terminal 101 When a transport block on the first uplink physical channel is transmitted in a certain subframe, it is determined that the terminal 101 transmits the first uplink physical channel in the subframe.

Way two

If the network device 102 determines that the terminal 101 abandons transmitting all the transport blocks on the first uplink physical channel in a certain subframe, the network device 102 determines that the terminal 101 abandons sending the first uplink physical channel in the subframe; if the network device 102 determines the terminal 101 When all the transport blocks on the first uplink physical channel are transmitted in a certain subframe, the network device 102 determines that the terminal 101 transmits the first uplink physical channel in the subframe.

When determining whether the terminal 101 relinquishes transmitting a transport block in a certain subframe, the following method may be specifically used: after the scheduling terminal 101 performs uplink service data transmission, the network device 102 waits for the transport block sent by the receiving terminal 101 in a predetermined subframe, For example, the subframe in which the transport block is received may be determined according to the scheduling timing, for example: the M frame scheduling in the LTE system, waiting for reception in the M+4 frame, etc.; the network device 102 according to whether the uplink demodulation reference corresponding to the transport block is received. The signal determines whether the terminal 101 gives up transmitting the transport block.

Specifically, the network device 102 detects whether the uplink demodulation reference signal corresponding to the transport block exists, and if yes, determines that the terminal 101 does not give up the transmission of the transport block, and records the data of the transport block received this time into the transport block. (Hybrid Automatic Repeat Request, HARQ) process processing, for example, for LTE or LTE-A system, if the network device 102 successfully receives the transport block for this time, it is included in the correct receiving information of the transport block, if the network device If the receiving of the transport block is successful, the received information of the transport block is used as the HARQ process in the merged data of the corresponding HARQ process; otherwise, the terminal 101 is determined to abandon the transmission of the transport block, and the data received this time is not counted. Into the HARQ process processing of the transport block.

Alternatively, in order to prevent the detection result of the DMRS signal from being misjudged, it is more accurately judged whether the terminal 101 abandons the transmission of the transport block. Alternatively, the network device 102 can also comprehensively judge, that is:

The network device 102 determines whether to receive the uplink demodulation reference signal corresponding to the transport block, and The predetermined subframe waits for the received energy of the uplink signal detected on the physical resource corresponding to the transport block, and determines whether the terminal 101 gives up transmitting the transport block.

Specifically, if the network device 102 receives the uplink demodulation reference signal corresponding to the transport block, and the energy of the uplink signal detected on the physical resource corresponding to the transport block that is waiting to be received in the predetermined subframe, and the received transmission If the ratio of the energy of the uplink demodulation reference signal corresponding to the block is greater than the preset energy ratio threshold, it is determined that the terminal 101 transmits the transport block.

In summary, when the network device 102 determines whether the terminal 101 abandons the first uplink physical channel, the following method can be used:

In the predetermined subframe, the network device 102 determines whether the terminal 101 abandons the transmission of the first uplink physical channel according to whether the uplink demodulation reference signal corresponding to the first uplink physical channel is received.

Specifically, when receiving the uplink demodulation reference signal corresponding to the first uplink physical channel, the network device 102 determines that the terminal 101 sends the first uplink physical channel; and when the uplink demodulation reference signal corresponding to the transport block is not received, It is determined that the terminal 101 abandons the transmission of the first uplink physical channel.

Alternatively, the network device 102 determines, according to whether the uplink demodulation reference signal corresponding to the first uplink physical channel is received, and the energy of the uplink signal detected on the physical resource corresponding to the first uplink physical channel that the predetermined subframe is waiting to receive. Whether the terminal 101 gives up transmitting the first uplink physical channel.

Specifically, if the network device 102 receives the uplink demodulation reference signal corresponding to the first uplink physical channel, and the energy of the uplink signal detected on the physical resource corresponding to the first uplink physical channel that is waiting to be received in the predetermined subframe, The ratio of the energy of the uplink demodulation reference signal corresponding to the first uplink physical channel is greater than the preset energy ratio threshold, and determining that the terminal 101 sends the first uplink physical channel.

Correspondingly, after scheduling the terminal to perform uplink service data transmission, the network device 102 waits for the first uplink physical channel sent by the receiving terminal 101 in a predetermined subframe;

If the network device 102 determines that the terminal 101 abandons the transmission of the first uplink physical channel, the network device 102 detects the uplink control information in the cell group to which the first uplink physical channel belongs and the second uplink physical channel used by the terminal 101. HARQ-ACK information indicating a downlink data reception condition and/or periodic indication information indicating a downlink channel state. If the network device 102 determines that the terminal 101 does not give up the transmission of the first uplink physical channel, the network device 102 detects the uplink control information in the cell group to which the first uplink physical channel belongs and the second uplink physical channel used by the terminal 101. Periodic indication information for indicating a downlink channel state;

And as described above, optionally, the network device 102 may further detect periodic indication information for indicating a downlink channel state on the first uplink physical channel, according to the periodic indication information respectively detected on the two uplink physical channels. And determining periodic indication information sent by the terminal 101.

Optionally, after the terminal 101 determines that at least a part of the uplink control information included in the first uplink physical channel is sent by using the second uplink physical channel, the terminal 101 re-determines the uplink physical channel to be sent. Transmit power.

Optionally, if the total transmit power of each uplink physical channel that is determined by the terminal 101 exceeds the maximum transmit power allowed by the terminal 101, the terminal 101 determines the transmit power of each uplink physical channel according to a preset power reduction rule, for example: If the required transmit power exceeds the maximum transmit power of the terminal, the power Scaling is performed, that is, the transmit power is scaled down.

The above describes the scheme in which the terminal sends the uplink control information and the network device receives the uplink control information in the embodiment of the present invention. Hereinafter, further exemplification will be given by way of specific examples.

Embodiment 1

The UE is served by CG1 or cell 1. In one TTI, the UE sends PUCCH-1 and PUSCH-1 to eNB1 that controls CG1 or cell 1. The sum of the power required to transmit PUCCH-1 and PUSCH-1 exceeds the maximum uplink transmit power of the UE. .

The UCI information included in PUSCH-1 is periodic CSI, and the UCI information included in PUCCH-1 is HARQ-ACK.

In the first embodiment, in order to protect the periodic HARQ-ACK in the PUCCH-1, the priority of assigning power to the PUCCH-1 is higher than the priority of allocating the channel for the PUSCH-1 channel. Therefore, the uplink transmit power of the UE is first allocated to the PUCCH-1 channel, and the remaining transmit power is allocated to PUSCH-1 channel. At this time, if the amount of UL-SCH service data in PUSCH-1 is very large, most of the power is used to transmit the part of the UL-SCH service data, and the power used to transmit the periodic CSI is only a small part. , unable to meet the receiving performance requirements of periodic CSI.

In this case, in the first embodiment, the periodic CSI in PUSCH-1 is placed on the PUCCH-1 channel transmission, and the UL-SCH data therein is discarded, so that sufficient power is allocated to the PUCCH-1 channel. Thereby meeting the performance requirements of periodic CSI transmission.

Optionally, the periodic CSI in the PUSCH-1 is placed on the PUCCH-1 channel transmission, and before the UL-SCH data is discarded, it is determined whether the transmit power of the periodic CSI in the PUSCH-1 channel is reduced to the first Below a threshold. If yes, the above process is performed; otherwise, the above process is not performed. The first threshold may be determined according to the receiving performance requirement of the periodic CSI, for example, according to the signal to noise ratio of the received signal of the periodic CSI.

Embodiment 2

In the case of Dual connectivity, the UE is served by CGI and CG2. In one frame, the UE transmits PUCCH-1 to the base station eNB1 controlling CG1, and transmits the PUSCH-1 including the UCI to the eNB2 controlling the CG2, and the sum of the powers required to transmit the PUCCH-1 and the PUSCH-1 exceeds the maximum uplink transmit power of the UE. .

The UE does not support PUCCH and PUSCH channel transmission at the same time, the UCI information included in PUSCH-1 is HARQ-ACK, and the UCI information included in PUCCH-1 transmitted to eNB1 is also HARQ-ACK.

In the second embodiment, CG1 is MCG and CG2 is SCG. To protect HARQ-ACK in the MCG, the priority of allocating power for PUCCH-1 is higher than that of assigning channels to PUSCH-1 channel. Therefore, the uplink transmission power of the UE is first allocated to the PUCCH-1 channel, and the remaining transmission power is allocated to the PUSCH-1 channel. At this time, if the amount of UL-SCH service data in PUSCH-1 is very large, most of the power is used to transmit the part of the UL-SCH service data therein, and the power used to transmit the HARQ-ACK part is only one of them. In part, the reception performance requirement of HARQ-ACK in PUSCH-1 cannot be met.

In this case, in the second embodiment, the HARQ-ACK in the PUSCH-1 is placed in the CG2. The PUCCH-2 channel transmits and discards the UL-SCH service data therein, so that the remaining power after allocating the power of the PUCCH-1 channel in the CG1 can be used to transmit the PUCCH-2 channel of the HARQ-ACK in the CG2, thereby satisfying as much as possible Receive performance requirements for HARQ-ACK in CG2.

Optionally, the HARQ-ACK in the PUSCH-1 is transmitted to the PUCCH-2 channel in the CG2, and before the UL-SCH data is discarded, it is required to determine whether the transmit power of the HARQ-ACK1 in the PUSCH-1 channel is Reduced to below the second threshold. If yes, the above process is performed, otherwise the above process is not executed. The second threshold may be determined according to a receiving performance requirement of the HARQ-ACK, for example, according to a received channel SNR of the HARQ-ACK.

Embodiment 3

In the case of Dual connectivity, the UE is served by CG1 and CG2. In one frame, the UE transmits PUCCH-1 to the base station eNB1 controlling CG1, and transmits the PUSCH-1 including the UCI to the eNB2 controlling the CG2, and the sum of the powers required to transmit the PUCCH-1 and the PUSCH-1 exceeds the maximum uplink transmit power of the UE. .

In the third embodiment, CG1 is SCG and CG2 is MCG. To protect HARQ-ACK in MCG, the priority of assigning power to PUSCH-1 is higher than that of assigning channel to PUCCH-1 channel. At this time, if the amount of UL-SCH service data in PUSCH-1 is very large, in order to meet the performance requirement of HARQ-ACK in PUSCH-1, too much power is allocated for the PUSCH-1, but most of the power is used. To send the part of the UL-SCH service data. After the power is allocated to the PUSCH-1 channel, the remaining power is allocated to the PUCCH-1 channel. As a result, the reception performance of the HARQ-ACK in the PUCCH-1 channel cannot meet the requirements.

In this case, in the third embodiment, the HARQ-ACK in the PUSCH-1 is transmitted to the PUCCH-2 channel in the CG2, and the UL-SCH channel therein is discarded, so as to make the HARQ in the PUCCH-1 channel as much as possible. - ACK is allocated enough power.

Optionally, placing the HARQ-ACK in PUSCH-1 into the PUCCH-2 channel transmission in CG2 Before transmitting, and discarding the UL-SCH channel therein, it is necessary to determine whether the transmission power of the HARQ-ACK in the PUCCH-1 channel is reduced below the third threshold. If yes, the above process is performed, otherwise the above process is not performed. The third threshold may be determined according to the receiving performance requirement of the HARQ-ACK, for example: according to the received channel SNR of the HARQ-ACK.

Embodiment 4

In the fourth embodiment, in order to protect HARQ-ACK, the priority of allocating power for PUSCH-1 and the priority of allocating power for PUCCH-1 channel are the same. At this time, if the amount of UL-SCH service data in PUSCH-1 is very large, in order to meet the performance requirement of HARQ-ACK in PUSCH-1, too much power is allocated to the PUSCH-1, but most of the power is used. To send the part of the UL-SCH service data. As a result, after the HARQ-ACK in the PUSCH-1 channel and the HARQ-ACK in the PUCCH channel are allocated power, the HARQ-ACK reception performance on both channels cannot meet the requirements.

In this case, in the fourth embodiment, the HARQ-ACK in the PUSCH-1 is transmitted to the PUCCH-2 channel in the CG2, and the UL-SCH data therein is discarded, so as to make the HARQ- in the CG1 and CG2 as much as possible. The ACK is allocated enough power to meet the performance requirements.

Optionally, the HARQ-ACK in the PUSCH-1 is transmitted to the PUCCH-2 channel in the CG2, and before the UL-SCH data is discarded, it is determined whether the transmit power of the HARQ-ACK in the PUSCH-1 channel is determined. Reduced to below the fourth threshold, and/or whether the transmit power of the HARQ-ACK in the PUCCH-1 channel is reduced below the fifth threshold. If yes, the above process is performed, otherwise the above process is not performed. Wherein, the fourth threshold and the fifth threshold are receivable according to HARQ-ACK The performance requirements are determined, for example: Depending on the received channel SNR of the HARQ-ACK.

Embodiment 5

The UE transmits the PUCCH and the PUSCH channel simultaneously in the CG2, the UCI information included in the PUSCH-1 is periodic CSI, and the UCI information included in the PUCCH-1 transmitted to the eNB1 is HARQ-ACK _0.

In order to protect HARQ-ACK, the priority assigned to PUCCH-1 is higher than the priority assigned to the PUSCH-1 channel. Therefore, the uplink transmit power of the UE is first allocated to the PUCCH-1 channel, and the remaining transmit power is allocated to the PUSCH-1 channel. At this time, if the amount of UL-SCH service data in PUSCH-1 is very large, most of the power is used to transmit the part of the UL-SCH service data, and the power used to transmit the periodic CSI is only one of them. A small part, thus unable to meet the receiving performance requirements of periodic CSI.

In this case, in the fifth embodiment, the periodic CSI in the PUSCH-1 is transmitted to the PUCCH-2 channel in the CG2, and the UL-SCH data therein is discarded, so that the power of the PUCCH-1 channel in the CG1 is allocated. The remaining residual power is first used to allocate the PUCCH-2 channel for transmitting periodic CSI in CG1, so as to satisfy the reception performance requirement of periodic CSI in CG2.

Optionally, since the power allocation level of the PUSCH-1 channel is lower than PUCCH-2, the PUCCH-2 of the CG2 is preferentially allocated with the transmission power, and if there is any remaining power, the remaining power is re-allocated to the PUSCH-1 channel.

Optionally, the periodic CSI in the PUSCH-1 is transmitted to the PUCCH-2 channel in the CG2, and before the UL-SCH data is discarded, it is required to determine whether the transmit power of the periodic CSI in the PUSCH-1 channel is Reduced to below the sixth threshold. If yes, the above process is performed, otherwise the above process is not performed. The sixth threshold may be determined according to the receiving performance requirement of the periodic CSI, for example, according to the received channel signal to noise ratio of the periodic CSI. The above description has been made from the cooperation between the terminal and the network device, but this does not mean that the two must cooperate with the implementation. In fact, when the terminal is implemented separately from the network device, the problems of the terminal and the network device are also respectively solved. Only when the two are combined, will get better technical results.

The method for solving the problem is similar to the above-mentioned wireless communication system provided by the embodiment of the present invention. The implementation of the wireless communication system can be referred to the implementation of the wireless communication system, and the details are not repeated here.
