Description

User equipment, access network equipment, and method for transmitting and receiving uplink control information Technical field

The present invention relates to the field of communications, and more particularly to a method for transmitting and receiving user equipment, access network equipment, and uplink control information in the field of wireless communications.

Background technique

In a long term evolution (LTE) system, downlink transmission is based on orthogonal frequency division multiplexing (OFDM), and uplink transmission is based on single carrier frequency division multiplexing multiple access (single carrier frequency division multiplexing) Access, SC-FDMA). LTE supports frequency division duplex (FDD) and time division duplex (TDD). For FDD systems, the downlink and uplink are transmitted on different carriers. For TDD systems, the uplink and downlink are transmitted at different times on the same carrier. The transmission of the service is based on an access network device, such as a base station, and the basic time unit of the base station scheduling is one subframe. The specific scheduling process is that the base station sends a control channel, such as a physical downlink control channel (PDCCH) or an enhanced PDCCH (EPDCCH), and the control channel can carry a data channel, such as a physical downlink shared channel (physical downlink shared channel). Channel, PDSCH) or scheduling information of a physical uplink shared channel (PUSCH), where the scheduling information includes control information such as resource allocation information and a modulation and coding scheme. A user equipment (UE) detects a control channel in a subframe, and receives a downlink data channel or an uplink data channel according to the detected scheduling information carried in the control channel.

Although the uplink data transmission is scheduled by the base station, the uplink data transmission is initiated by the UE, and the base station obtains the uplink data scheduling of the UE after the UE initiates the message, and the initiation message passes the physical uplink control channel in the LTE system (physical The uplink control channel (PUCCH) is sent by sending a scheduling request (SR). Specifically, the base station configures the resources of the SR for the UE in advance, and the resources of the SR are generally configured to be in a certain period. If the UE does not have an uplink data transmission requirement, the UE does not send a signal on the periodically occurring SR resource. On the contrary, once the UE has an uplink data transmission requirement, the UE will be on the SR resource that periodically appears. The SR signal is transmitted, and the base station determines whether the UE has transmitted the SR by detecting the energy of the SR resource. The PUCCH format in which the SR is transmitted in the LTE system is PUCCH format 1.

LTE adopts a hybrid automatic repeat request (HARQ) mechanism. In the following behavior example, after the UE receives the PDSCH, if the PDSCH is correctly received, the UE feeds back an acknowledgement (ACK) on the PUCCH, and if the PDSCH is not correctly received, the non acknowledgement (NACK) is sent back on the PUCCH. The PUCCH format for transmitting the ACK/NACK is PUCCH format 1a or 1b. If the subframe in which the UE feeds back the ACK/NACK on the PUCCH is also the subframe in which the SR resource is located, then if the UE does not have the uplink data transmission requirement, the UE transmits the ACK/NACK on the PUCCH format 1a or 1b of the ACK/NACK; On the other hand, if the UE has an uplink data transmission requirement at this time, the UE transmits an ACK/NACK on the PUCCH format 1 of the SR.

LTE also supports carrier aggregation (CA) technology, that is, the base station configures multiple carriers to one UE to increase the data rate of the UE. The multiple carriers are synchronously transmitted in the time domain, and the UE may separately detect the PDCCH and the PDCCH corresponding to the PDCCH for each carrier, where the specific detection process of each carrier is similar to the single carrier case described above. Since the data scheduling of multiple downlink carriers is to independently feed back ACK/NACK in the CA mode, the number of ACK/NACK bits is more than that in the single carrier mode. Therefore, in addition to PUCCH format 1a or 1b, PUCCH is introduced. Format 3, PUCCH format 3 uses Discrete Fourier Transform-spread-OFDM (DFT-S-OFDM) transmission mode, and can transmit at least 20 ACK/NACK bits. The ACK/NACK number is significantly larger than the PUCCH format 1a or 1b. Generally, in the CA mode, the UE is configured with one primary carrier and at least one secondary carrier, and the PUCCH is only sent on the primary carrier of the UE. In addition, when the subframe in which the UE transmits the ACK/NACK using the PUCCH format 3 is also the subframe in which the SR resource is located, then the ACK/NACK is jointly encoded with the SR and transmitted on the resource of the PUCCH format 3. Specifically, the number of original bits before encoding on the PUCCH format 3 is to leave a position of 1 bit for the SR. For example, the SR is at the end of the ACK/NACK bit. If the UE has an uplink data transmission requirement at this time, the reserved SR position. The 1-bit mapping is '1'. Conversely, if the UE does not have an uplink data transmission requirement at this time, the 1-bit of the reserved SR location is mapped to '0'.

As LTE technology continues to evolve, it may be necessary to support more bits in the future. ACK/NACK feedback, such as much larger than 20 bits. Therefore, it is highly probable that a new PUCCH format with a larger bit capacity than PUCCH format 3 will be introduced. Due to the increase in bit capacity, the overhead of the new PUCCH format should be larger than that of PUCCH format 3, and/or multiplexing capability. It is lower than PUCCH format 3. It is also considered that the current PUCCH is carried on the primary carrier, and the primary carriers of a large number of UEs may be the same, resulting in a large PUCCH overhead on the primary carrier. An enhanced PUCCH transmission mechanism is to introduce a PUCCH for transmission on multiple carriers, for example, selecting a secondary carrier from a secondary carrier group to carry a PUCCH, and the secondary carrier carrying the PUCCH may be referred to as a PUCCH secondary carrier. In this way, the UE can transmit two PUCCHs in parallel through the primary carrier and the PUCCH secondary carrier, respectively, which alleviates the problem that the PUCCH load on the primary carrier is heavy. Specifically, assuming that the UE is configured with 32 carriers, the base station can configure the UE to transmit the ACK/NACK of the carriers 1 to 16 on the PUCCH of the primary carrier, and transmit the ACK/NACK of the carriers 17 to 32 on the PUCCH secondary carrier. However, for the SR, whether it is the single carrier mode or the CA mode, the SR is to indicate whether there is an uplink data transmission requirement. Therefore, from the perspective of the SR content, even in the CA mode, the UE needs to transmit only one SR. That is, it is consistent with the requirement of transmitting SR in single carrier mode. However, although the content of the SR is consistent with the single carrier mode, the load of offloading a portion of the SR to the SCell may also be considered. Therefore, in the dual PUCCH mode, how to transmit the SR is an urgent problem to be solved.

detailed description

The technical solutions in the embodiments of the present invention are clearly and completely described in the following with reference to the accompanying drawings in the embodiments of the present invention. It is obvious that the described embodiments are only a part of the embodiments of the present invention, but not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without creative efforts are within the scope of the present invention.

The PUCCH is transmitted simultaneously on the primary carrier and the PUCCH secondary carrier. Compared with transmitting the PUCCH only on the primary carrier, there is a problem that the maximum power backoff occurs in the uplink single radio frequency chain. This uplink dual PUCCH transmission breaks the characteristics of the uplink single carrier FDMA. The maximum power backoff will result in a certain degree of power efficiency degradation, especially under the condition that the UE transmit power is limited, which is also the cost of transmitting dual PUCCH to implement PUCCH overhead offloading. Based on this, it is considered that the content of the SR in the CA mode is actually the same as the content of the SR under the single carrier. Therefore, in some scenarios, double PUCCH transmission can be avoided. Specifically, for the SR transmission in the dual PUCCH mode, the following scenarios may be considered:

Scene 1: SRs on two PUCCHs collide at the same time

In general, the SR on the PUCCH of the primary carrier and the SR on the secondary carrier of the PUCCH are independent configuration periods and transmission subframes, which may cause the SRs on the two PUCCHs to be configured in the same uplink subframe, that is, simultaneously collide. At this point, you can consider the following two sub-scenarios:

Sub-scenario 1: On the uplink subframe in which the SR is collided, ACK/NACK needs to be sent on both PUCCHs.

In this sub-scenario, because the respective ACK/NACKs on the two PUCCHs are generally corresponding to different carriers and/or different downlink subframes, the dual PUCCHs need to be sent anyway to carry different carriers and/or different downlinks respectively. The ACK/NACK corresponding to the subframe respectively. Then, at this time, the case where the SR is present can be assumed on both PUCCHs. For example, if both PUCCHs adopt a new format of PUCCH format 3 or larger capacity, one bit can be reserved for each SR on each of the two PUCCHs. In this way, compared to the scheme of transmitting the SR on only one PUCCH and discarding the SR on the other PUCCH, there is an advantage of SR diversity reception, that is, the base station can obtain the performance gain of the diversity receiving SR at the receiving end. Specifically, it is assumed that ACK/NACK and SR error detection in the PUCCH on the primary carrier, such as a cyclic redundancy check (CRC), does not pass the check, and the CRC on the PUCCH on the PUCCH secondary carrier passes the check. Then, the base station still obtains the SR information sent by the UE to determine whether the UE has the requirement for uplink data transmission. In addition, in general, the number of bits of the SR 1 bit is very small compared to the ACK/NACK, so the SR reserved for 1 bit on both PUCCHs does not substantially affect the demodulation performance of the PUCCH.

Sub-scenario 2: On the uplink subframe in which the SR is collided, only one of the two PUCCHs needs to send an ACK/NACK.

It is assumed that an ACK/NACK needs to be sent on the PUCCH on the primary carrier at this time. The ACK/NACK does not need to be sent on the PUCCH secondary carrier at this time. For example, the downlink carrier and/or the downlink subframe corresponding to the PUCCH on the PUCCH secondary carrier are not scheduled by the base station. On the other hand, the case where the ACK/NACK is not required to be transmitted on the primary carrier, and the ACK/NACK needs to be sent on the PUCCH on the PUCCH secondary carrier is similar. The former is described as an example.

Under the above assumptions, the direct PUCCH transmission mechanism should be that the UE needs to consider the SR when transmitting the ACK/NACK on the primary carrier, for example, the PUCCH transmitted on the primary carrier includes ACK/NACK and SR, and only the PUCCH secondary carrier is included. PUCCH format 1 is transmitted to carry the SR without transmitting an ACK/NACK. The disadvantage of this mechanism is that the SR sent separately will not have the single-carrier FDMA feature for the uplink transmission at this time, resulting in the maximum power back-off and the power effect of the uplink transmission. In addition, since the information represented by the SR sent by the two PUCCHs is actually an information content, the diversity gain brought by the simultaneous transmission of the SR may not be sufficient to compensate for the loss of power efficiency caused by the uplink dual PUCCH transmission, and for the sub-scene. 1. Dual PUCCH transmission is unavoidable because the ACK/NACK transmitted on the two PUCCHs is independent.

Scenario 2: SRs on two PUCCHs are not touched at the same time

Generally, the SR on the PUCCH of the primary carrier and the SR on the secondary carrier of the PUCCH are independent configuration periods and transmission subframes. Therefore, the SRs on the two PUCCHs can be configured on different uplinks through independent configuration of the SR. Subframes, that is, different times. At this point, consider the following three sub-scenarios:

Sub-scenario 1: ACK/NACK needs to be sent on both PUCCHs, but only one PUCCH has SR configuration.

Since both ACK/NACK need to be sent on both PUCCHs, the dual PUCCH needs to be transmitted at this time. For the SR, since only one PUCCH is configured with the SR, only the joint transmission of the SR and the ACK/NACK on the PUCCH can be considered, and the SR transmission is not considered on the other PUCCH without the SR. Or, although there is no SR configuration on another PUCCH, it is considered that the dual PUCCH will be transmitted at this time, and the SR reserved for one bit has little influence on the demodulation performance of the PUCCH, and the gain of the SR diversity reception can also be obtained. Therefore, an SR reserved for 1 bit on each of the two PUCCHs can be considered.

Sub-Scenario 2: Only one PUCCH needs to be sent on two PUCCHs ACK/NACK, and the SR configuration at this time is on the PUCCH that transmits the ACK/NACK.

At this time, only one PUCCH needs to be transmitted, and the transmission of the SR is considered on the PUCCH, for example, with ACK/NACK.

Sub-scenario 3: ACK/NACK needs to be sent on only one PUCCH on two PUCCHs, and the SR configuration at this time is on the PUCCH that does not transmit ACK/NACK.

It is assumed that the ACK/NACK needs to be sent on the PUCCH on the primary carrier at this time, and the ACK/NACK is not required to be sent on the PUCCH secondary carrier at this time. For example, the downlink carrier and/or the downlink subframe corresponding to the PUCCH on the PUCCH secondary carrier are not scheduled by the base station. . On the other hand, the case where the ACK/NACK is not required to be transmitted on the primary carrier, and the ACK/NACK needs to be sent on the PUCCH on the PUCCH secondary carrier is similar. The former is described as an example.

Under the above assumption, the direct PUCCH transmission mechanism should be that the UE does not need to consider the SR when transmitting the ACK/NACK on the primary carrier. For example, the PUCCH sent on the primary carrier includes the ACK/NACK and does not include the SR, but is supplemented by the PUCCH. Only PUCCH format 1 is transmitted on the carrier to carry the SR without transmitting ACK/NACK. The disadvantage of this mechanism is that the SR sent separately will not have the single-carrier FDMA feature for the uplink transmission at this time, resulting in the maximum power back-off and the power effect of the uplink transmission. Therefore, considering that the period of the SR and the transmission subframe are pre-configured, the SR configured on the PUCCH secondary carrier at this time may be transmitted on the PUCCH of the primary carrier, that is, transmitted together with the ACK/NACK of the primary carrier, without The SR is retransmitted on the PUCCH secondary carrier.

Based on the description of the problem, the solution, and the corresponding effect in the foregoing scenarios, FIG. 1 is a method for sending uplink control information according to the present invention, which is used by the UE side:

Step 101: The UE determines a primary carrier and a secondary carrier group, where the secondary carrier group includes at least one secondary carrier, and the at least one secondary carrier includes at least one PUCCH secondary carrier, where the primary carrier and the PUCCH secondary carrier are configured. The PUCCH can be transmitted simultaneously;

It should be noted that, although the embodiment of the present invention is described by taking one PUCCH secondary carrier as an example, the solution of the embodiment of the present invention is not limited thereto, and may also be applied to a scenario of at least two PUCCH secondary carriers.

Step 102: The UE determines that the primary carrier is on the PUCCH secondary carrier. Transmission configuration of ACK/NACK and SR in an uplink subframe;

Step 103: The UE sends a PUCCH in the uplink subframe according to the sending configuration.

Through the above method, when the UE is configured in the dual PUCCH mode, the transmission of the SR and the ACK/NACK in the mode is implemented, and the problem that the SR is jointly transmitted with the ACK/NACK in the dual PUCCH mode is solved.

It should be noted that simultaneously transmitting PUCCH means that the UE can separately send multiple PUCCHs in the same subframe on different carriers.

Optionally, the UE determines, in the uplink subframe, an ACK/NACK on the primary carrier and the PUCCH secondary carrier, and a sending configuration in the uplink subframe, where the UE is in the uplink subframe according to the sending configuration. The sending of the PUCCH includes: when the ACK/NACK needs to be sent on the primary carrier, and the ACK/NACK is not required to be sent on the PUCCH secondary carrier, and the SR is configured on the primary carrier and the PUCCH secondary carrier. Transmitting, by the UE, an ACK/NACK and an SR on a PUCCH on the primary carrier, and not transmitting an SR on a PUCCH on the PUCCH secondary carrier; or, when the primary carrier does not need to send an ACK/NACK, When the ACK/NACK needs to be sent on the PUCCH secondary carrier, and the SR is configured on the primary carrier and the PUCCH secondary carrier, the UE sends an ACK/NACK and an SR on the PUCCH on the PUCCH secondary carrier. The SR is not transmitted on the PUCCH on the primary carrier.

It should be noted that the foregoing transmission configuration refers to a situation in which the UE determines the configuration of the base station for the SR and the scheduling of the downlink data to determine whether the ACK/NACK needs to be transmitted on the PUCCH.

Further, when an ACK/NACK needs to be sent on the primary carrier and the PUCCH secondary carrier, and an SR is configured on the primary carrier and the PUCCH secondary carrier, the UE is in the primary carrier. The first part of the ACK/NACK and the SR are sent on the PUCCH, and the UE sends the second part of the ACK/NACK and the SR on the PUCCH on the PUCCH secondary carrier.

Further, the UE sends an ACK/NACK and an SR on a PUCCH format 3 or a new PUCCH format on the primary carrier; or the UE sends on a PUCCH format 3 or a new PUCCH format on the PUCCH secondary carrier. ACK/NACK and SR.

It should be noted that the above mentioned transmission of ACK/NACK and SR on the primary carrier or the PUCCH secondary carrier means that the SR is considered while transmitting the ACK/NACK. For example, for the PUCCH format 3 or the new PUCCH format, if the UE does not have an uplink data transmission requirement, the reserved 1-bit SR on the PUCCH is set to '0'; otherwise, if the UE has an uplink data transmission requirement, the reserved 1 on the PUCCH Bit SR is set to '1'. For example, for PUCCH format 1a or 1b, if the UE does not have an uplink data transmission requirement, the UE sends an ACK/NACK on the resource of the PUCCH format 1a or 1b of the ACK/NACK; otherwise, if the UE has an uplink data transmission requirement, the UE The ACK/NACK is transmitted on the resource of the PUCCH format 1 of the SR.

Taking FIG. 2 as an example, FIG. 2(a) assumes that ACK/NACK needs to be sent on both the primary carrier and the PUCCH secondary carrier, such as ACK/NACK of the downlink data channel scheduled on downlink carriers 1 to 16 in the first downlink carrier set. It needs to be sent on the PUCCH on the primary carrier, and the ACK/NACK of the downlink data channel scheduled on the downlink carriers 17 to 32 in the second downlink carrier set needs to be sent on the PUCCH on the PUCCH secondary carrier, and the UE just received the same before. For scheduling of downlink data from the first downlink carrier set and the second downlink carrier set, the UE needs to send ACK/NACK on the primary carrier PUCCH and the PUCCH of the PUCCH secondary carrier in the current uplink subframe. It is further assumed that in the uplink subframe in which the ACK/NACK needs to be sent, the UE is configured with the SR on the primary carrier and the PUCCH secondary carrier in advance, and then the UE can perform ACK/NACK and SR transmission in the two PUCCHs. For example, if both PUCCHs are transmitted in PUCCH format 3, then one SR bit is reserved in each PUCCH format 3. This scheme is also applicable to the case of considering SR transmission in other PUCCH formats. Through this scheme, the diversity transmission of the SR can be achieved, and the diversity reception of the SR on the access network device side is improved, and the reception performance of the SR is improved, and the temporarily increased SR transmission does not substantially receive the ACK/NACK. Make an impact.

Figure 2 (b) assumes that the ACK/NACK needs to be sent on the primary carrier, and the ACK/NACK is not required to be sent on the PUCCH secondary carrier. For example, the UE receives the downlink data scheduled on the downlink carriers 1 to 16 in the first downlink carrier set. The channel does not receive the downlink data channel scheduled on the downlink carriers 17 to 32 in the second downlink carrier set. It is further assumed that in the uplink subframe in which the ACK/NACK needs to be sent, the UE is configured with the SR on the primary carrier and the PUCCH secondary carrier in advance, and the UE may consider the transmission of the SR on the PUCCH that sends the ACK/NACK, that is, on the primary carrier. PUCCH, but not on PUCCH secondary carrier Consider the transmission of the SR. Through this scheme, the uplink power efficiency can be improved, and the transmission of the SR is not affected because the contents of the two SRs are consistent.

Optionally, the UE determines, in the uplink subframe, an ACK/NACK on the primary carrier and the PUCCH secondary carrier, and a sending configuration in the uplink subframe, where the UE is in the uplink subframe according to the sending configuration. The sending of the PUCCH includes: when the ACK/NACK needs to be sent on the primary carrier and the PUCCH secondary carrier, and the SR is configured on the primary carrier and the SR is not configured on the secondary carrier of the PUCCH, Transmitting, by the UE, a first partial ACK/NACK and an SR on a PUCCH on the primary carrier, and sending, by the UE, a second partial ACK/NACK and an SR on a PUCCH on the PUCCH secondary carrier; or When the ACK/NACK needs to be sent on the primary carrier and the PUCCH secondary carrier, and the SR is not configured on the primary carrier and the SR is configured on the secondary carrier, the UE is on the primary carrier. The first part of the ACK/NACK and the SR are transmitted on the PUCCH, and the UE transmits the second part of the ACK/NACK and the SR on the PUCCH on the PUCCH secondary carrier.

Further, the UE sends an ACK/NACK and an SR on a PUCCH format 3 or a new PUCCH format on the primary carrier; or the UE sends on a PUCCH format 3 or a new PUCCH format on the PUCCH secondary carrier. ACK/NACK and SR.

As shown in FIG. 3, it is assumed that an ACK/NACK needs to be sent on both the primary carrier and the PUCCH secondary carrier. For example, the ACK/NACK of the downlink data channel scheduled on the downlink carriers 1 to 16 in the first downlink carrier set needs to be on the primary carrier. On the PUCCH, the ACK/NACK of the downlink data channel scheduled on the downlink carriers 17 to 32 in the second downlink carrier set needs to be sent on the PUCCH on the PUCCH secondary carrier, and the UE just receives the first from the first For scheduling of downlink data in the row carrier set and the second downlink carrier set, the UE needs to send ACK/NACK on the PUCCH of the primary carrier PUCCH and the PUCCH secondary carrier in the current uplink subframe. Assuming that the UE needs to send the ACK/NACK in the uplink subframe, the UE is configured with the SR on the primary carrier, and the SR is not configured on the PUCCH secondary carrier. Then, the UE can perform ACK in the two PUCCHs. /NACK and SR transmission. For example, if both PUCCHs are transmitted in PUCCH format 3, then one SR bit is reserved in each PUCCH format 3. This scheme is also applicable to the case of considering SR transmission in other PUCCH formats. Through this scheme, the diversity transmission of the SR can be achieved, and the corresponding SR on the access network device side Diversity reception improves SR reception performance. In addition, although the SR is not configured on the PUCCH secondary carrier, the temporarily increased SR transmission does not substantially affect the reception performance of the ACK/NACK.

Optionally, the UE determines, in the uplink subframe, an ACK/NACK on the primary carrier and the PUCCH secondary carrier, and a sending configuration in the uplink subframe, where the UE is in the uplink subframe according to the sending configuration. The sending of the PUCCH includes: when the ACK/NACK needs to be sent on the primary carrier, and the ACK/NACK is not required to be sent on the PUCCH secondary carrier, and the primary carrier is not configured with the SR but the PUCCH secondary carrier is When the SR is configured, the UE sends an ACK/NACK and an SR on the PUCCH on the primary carrier, and does not send an SR on the PUCCH on the PUCCH secondary carrier; or, when the primary carrier does not need to send an ACK If the ACK/NACK needs to be sent on the PUCCH secondary carrier and the SR is configured on the primary carrier and the SR is not configured on the PUCCH secondary carrier, the PUCCH of the UE on the PUCCH secondary carrier is The ACK/NACK and the SR are transmitted without transmitting the SR on the PUCCH on the primary carrier.

Further, the UE sends an ACK/NACK and an SR on a PUCCH format 3 or a new PUCCH format on the primary carrier; or the UE sends on a PUCCH format 3 or a new PUCCH format on the PUCCH secondary carrier. ACK/NACK and SR.

As shown in FIG. 4, it is assumed that the ACK/NACK needs to be sent on the primary carrier, and the ACK/NACK is not required to be sent on the PUCCH secondary carrier. For example, the UE receives the downlink scheduled on the downlink carriers 1 to 16 in the first downlink carrier set. The data channel does not receive the downlink data channel scheduled on the downlink carriers 17 to 32 in the second downlink carrier set. It is assumed that in the uplink subframe in which the ACK/NACK needs to be sent, and in the uplink subframe in which the ACK/NACK needs to be sent, the UE is not configured with the SR on the primary carrier, and the SR is configured in advance on the PUCCH secondary carrier. Then, at this time, the UE may abandon the SR transmission on the PUCCH secondary carrier, and move the transmission of the SR to the PUCCH of the primary carrier, that is, perform ACK/NACK and SR transmission on the PUCCH on the primary carrier. With this scheme, the uplink power efficiency can be improved, and the transmission of the SR is not affected, because the transmission of the SR is only the carrier being moved.

In addition, the embodiment of FIG. 4 is particularly applicable to PUCCH format 3 and PUCCH. The new format, because both SR and ACK/NACK are sent in this PUCCH format 3 or new format. This scheme is not suitable for PUCCH format 1a or 1b. Therefore, once the UE has uplink data transmission requirements, the UE should send the SR's own PUCCH format 1 resource, and the uplink subframe is not configured on the primary carrier. SR resources. If you want to support PUCCH format 1a or 1b and the SR does not necessarily apply the same resources, you can always allocate resources for the SR.

FIG. 5 is a schematic diagram of a method for receiving uplink control information, which is used by an access network device side:

Step 501: The access network device determines a primary carrier and a secondary carrier group of the UE, where the secondary carrier group includes one PUCCH secondary carrier, where the primary carrier and the PUCCH secondary carrier are carriers configured for the UE to simultaneously transmit the PUCCH. ;

Step 502: The access network device determines, according to the ACK/NACK on the primary carrier and the PUCCH secondary carrier, and the receiving configuration of the SR in the uplink subframe.

Step 503: The access network device receives the PUCCH in the uplink subframe according to the receiving configuration.

Through the foregoing method, when the access network device configures the dual PUCCH mode for the UE, the transmission of the SR and the ACK/NACK in the mode is implemented, and the problem that the SR is jointly transmitted with the ACK/NACK in the dual PUCCH mode is solved.

Optionally, the access network device determines an ACK/NACK on the primary carrier and the PUCCH secondary carrier, and a receiving configuration of the SR in an uplink subframe, where the access network device is configured according to the receiving, The receiving the PUCCH in the uplink subframe includes: when the ACK/NACK needs to be received on the primary carrier, the ACK/NACK is not required to be received on the PUCCH secondary carrier, and the access network device is the UE When the SR is configured on the primary carrier and the PUCCH secondary carrier, the access network device receives an ACK/NACK and an SR on a PUCCH on the primary carrier, and does not use a PUCCH on the PUCCH secondary carrier. Receiving an SR; or, when the primary carrier does not need to receive an ACK/NACK, the PUCCH secondary carrier needs to receive an ACK/NACK, and the access network device is the UE in the primary carrier and the When the SR is configured on the PUCCH secondary carrier, the access network device receives the ACK/NACK and the SR on the PUCCH on the PUCCH secondary carrier, and does not receive the SR on the PUCCH on the primary carrier.

Further, when the access network device is on the primary carrier and the PUCCH is secondary The ACK/NACK needs to be received on the carrier, and the access network device is configured to perform the SR on the primary carrier and the PUCCH secondary carrier, where the access network device is in the primary carrier. The first part of the ACK/NACK and the SR are received on the PUCCH, and the access network device receives the second part of the ACK/NACK and the SR on the PUCCH on the PUCCH secondary carrier.

Further, the access network device receives the ACK/NACK and the SR on the PUCCH format 3 or the new PUCCH format on the primary carrier; or the PUCCH format 3 of the access network device on the PUCCH secondary carrier Or receive ACK/NACK and SR on the new PUCCH format.

It should be noted that the above mentioned receiving ACK/NACK and SR on the primary carrier or the PUCCH secondary carrier means that the potential existence of the SR is considered while receiving the ACK/NACK. For example, for the PUCCH format 3 or the new PUCCH format, the access network device assumes that a position of 1 bit is reserved for the SR on the PUCCH, and if the received SR bit is '0', it indicates that the UE has no uplink data transmission. On the other hand, if the received SR bit is '1', it indicates that the UE has a requirement for uplink data transmission. For example, for the PUCCH format 1a or 1b, the access network device needs to perform ACK/NACK energy detection on the resources of the PUCCH format 1 of the SR and the resources of the PUCCH format 1a or 1b of the ACK/NACK, if the access is performed. If the energy detection on the resource of the PUCCH format 1 exceeds the preset threshold, the network device indicates that the UE has an uplink data transmission requirement, and the access network device further continues to receive the ACK/NACK on the resource of the PUCCH format 1; On the other hand, if the energy detection of the access network device on the resources of the PUCCH format 1a or 1b exceeds a preset threshold, it indicates that the UE does not have an uplink data transmission requirement, and the access network device continues to be in the PUCCH format 1a or The ACK/NACK is received on the 1b resource.

Optionally, the access network device determines an ACK/NACK on the primary carrier and the PUCCH secondary carrier, and a receiving configuration of the SR in an uplink subframe, where the access network device is configured according to the receiving, The receiving the PUCCH in the uplink subframe includes: receiving an ACK/NACK on the primary carrier and the PUCCH secondary carrier, where the access network device is the primary carrier of the UE When the SR is configured and the SR is not configured on the PUCCH secondary carrier, the access network device receives the first partial ACK/NACK and the SR on the PUCCH on the primary carrier, and the access network device is in the PUCCH Receiving a second part of ACK/NACK and SR on the PUCCH on the secondary carrier; Or, the ACK/NACK needs to be received on the primary carrier and the PUCCH secondary carrier, and the access network device does not configure an SR on the primary carrier of the UE but is configured on the PUCCH secondary carrier. When the SR is used, the access network device receives a first partial ACK/NACK and an SR on a PUCCH on the primary carrier, and the access network device receives a second partial ACK on a PUCCH on the PUCCH secondary carrier. /NACK and SR.

Further, the access network device receives the ACK/NACK and the SR on the PUCCH format 3 or the new PUCCH format on the primary carrier; or the PUCCH format 3 of the access network device on the PUCCH secondary carrier Or receive ACK/NACK and SR on the new PUCCH format.

Optionally, the access network device determines an ACK/NACK on the primary carrier and the PUCCH secondary carrier, and a receiving configuration of the SR in an uplink subframe, where the access network device is configured according to the receiving, The receiving the PUCCH in the uplink subframe includes: when the ACK/NACK needs to be received on the primary carrier, and the ACK/NACK is not required to be received on the PUCCH secondary carrier, and the access network device is the UE When the SR is not configured on the primary carrier and the SR is configured on the secondary carrier, the access network device receives the ACK/NACK and the SR on the PUCCH on the primary carrier, but not on the PUCCH secondary carrier. Receiving an SR on the PUCCH; or, when the primary carrier does not need to receive an ACK/NACK, the PUCCH secondary carrier needs to receive an ACK/NACK, and the access network device is on the primary carrier of the UE When the SR is configured and the SR is not configured on the PUCCH secondary carrier, the access network device receives the ACK/NACK and the SR on the PUCCH on the PUCCH secondary carrier, and does not receive the SR on the PUCCH on the primary carrier. .
