Description

TECHNICAL FIELD The present invention relates to the field of communications, and in particular, to a method and an apparatus for validating a Hybrid Automatic Repeat Request (HQQ) timing relationship.

Background technique

The LTE (Long Term Evolution) system supports the TDD (Time Division Duplexing) mode, that is, UL (Uplink, uplink) and DL (Downlink) use different time slots of the same frequency. The LTE TDD system can select different uplink and downlink configurations (upstream and downlink configurations, that is, the proportion of the uplink and downlink subframes and the location) according to different service types, so as to meet different uplink and downlink asymmetric service requirements.

In the current LTE TDD system, the HARQ of the downlink data is asynchronously adaptive, and in order to reduce the overhead of the control information, the HARQ of the uplink data is performed in a synchronous adaptive manner, wherein the HARQ timing relationship of the downlink data includes: PDSCH The timing relationship between the physical downlink shared channel (Physical downlink shared channel) and the PUCCH (Physical uplink control channel) HARQ_ACK; the HARQ timing relationship of the uplink data includes: downlink DCD (downlink control inf ormat) Between the PDCCH (Physical Downlink Control Channel) or the ePDCCH (Enhanced PDCCH, enhanced downlink control channel) and the corresponding PUSCH (Physical Uplink Shared Channel) Timing relationship, and the timing relationship between the PUSCH and the PHICH. Because the ratios of the uplink and downlink subframes and the location are different in different uplink and downlink configurations, the timing relationships corresponding to different uplink and downlink configurations are different.

In the new LTE TDD system, the uplink and downlink configuration used is dynamically changed, for example, 10ms-40ms is changed once, and the current uplink and downlink configuration does not match the instantaneous uplink and downlink traffic when the uplink and downlink configuration is semi-statically configured. At the same time, the uplink reference configuration type and the downlink reference configuration type are respectively introduced in the new version of the system. Regardless of the actual uplink and downlink configuration changes, the HARQ timing relationship of the uplink data only uses the HARQ timing relationship of the uplink reference configuration type, and the downlink data. HARQ timing relationship using HARQ timing closure of downlink reference configuration The HARQ timing relationship of the uplink reference configuration refers to the HARQ timing relationship corresponding to the uplink part in the uplink and downlink configuration, and the HARQ timing relationship of the downlink reference configuration refers to the downlink subframe in the uplink and downlink configuration (including the special subframe). Downstream part) Corresponding HARQ timing relationship. The uplink reference configuration type and the downlink reference configuration type may be carried in an RRC (radio resource QoS) reconfiguration message, and sent by the eNB (evo ved Node B, evolved base station) to the UE (U ser Equ i pmen t, user equipment), instructing the UE to update the uplink reference configuration type and the downlink reference configuration type, thereby obtaining a new HARQ timing relationship. In the prior art, after the UE successfully receives the RRC reconfiguration message, the configuration parameters in the RRC reconfiguration message are immediately effective, so that the UE immediately uses the new HARQ corresponding to the new uplink and downlink reference configuration type. When the eNB does not receive the RRC reconfiguration complete message of the UE, the eNB cannot determine whether the UE successfully receives the RRC reconfiguration message, so that the eNB still uses the HARQ timing relationship corresponding to the original uplink and downlink reference configuration. In this way, the eNB and the UE may use different HARQ timing relationships. In the existing RRC connection reconfiguration process, the PDCCH uplink grant message sent by the eNB must be received before the UE feeds back the RRC reconfiguration complete message. The eNB sends a PDCCH uplink grant message in the subframe N according to the original downlink reference configuration, and the UE sends the PDCCH uplink grant message in the uplink subframe of the subframe N+4 according to the new HARQ timing relationship. The PUSCH, the PUSCH carries the RRC reconfiguration complete message of the UE, and the base station may also receive the corresponding PUSCH in the uplink subframe N+5 according to the original HARQ timing relationship. ENB can not sample the received frames on the PUSCH in the right sub RRC reconfiguration complete message, resulting in failure of the RRC reconfiguration, RRC re-establishment will cause again, ultimately affect the user experience and reduce the capacity of the system.

The HARQ timing relationship of the downlink data is the HARQ timing relationship corresponding to the uplink and downlink reference configurations in Table 3 and Table 4. The uplink and downlink reference configuration is carried in an RRC reconfiguration message and sent by the eNB to the UE. Embodiment 1: The embodiment of the present invention provides a method for implementing a hybrid automatic retransmission timing relationship, where the execution subject is a UE. As shown in FIG. 1, the method includes the following steps:

101. Receive a radio resource control RRC reconfiguration message sent by an evolved base station eNB. The RRC reconfiguration message carries information related to the HARQ timing relationship, and the information related to the HARQ timing relationship includes at least one of the following information: uplink reference configuration information, downlink reference information, and elMTA (Further Enhancements) To LTE TDD for DL-UL Interference Management and Traffic Adaptation, further enhancing downlink downlink interference management and service adaptation of LTE TDD) function off information and elMTA function enable information.

After the UE receives the RRC reconfiguration message, the information related to the HARQ timing relationship in the RRC reconfiguration message does not take effect immediately. The information related to the HARQ timing relationship mainly refers to the reference configuration information and the downlink reference configuration information. , elMTA function off (elMTA disable) message or elMTA function enable (enable elMTA functionality) message.

102. Receive the effective indication signaling sent by the eNB, where the effective indication signaling includes: physical layer multicast signaling, or physical layer broadcast signaling, or medium access control MAC signaling.

After receiving the RRC reconfiguration message, the UE receives the indication information of the effective indication sent by the eNB, and the effective indication signaling may be physical layer multicast signaling, or physical layer broadcast signaling, or MAC (Media Access Control) , Media Access Control) Signaling. For example, the physical layer multicast signaling or the physical layer broadcast signaling may be UE group-specific PDCCH signaling (UE-group-common PDCCH) signaling.

103. Determine, according to the received indication signaling, whether to use the HARQ timing relationship corresponding to the information related to the HARQ timing relationship.

The moment when the effective indication signaling is sent may be specified by the LTE TDD system or given by the standard, or may be sent by the eNB to the UE. Optionally, the UE determines, according to the received indication signaling, whether to use the HARQ timing relationship corresponding to the information related to the HARQ timing relationship, where the UE has received the following: The effective indication signaling determines the HARQ timing relationship corresponding to the information related to the HARQ timing relationship. In this manner, when the eNB sends the validity indication signaling, the eNB uses the HARQ timing relationship corresponding to the information related to the HARQ timing relationship. Alternatively, the UE may determine, according to the content of the received indication signaling, whether to use the HARQ timing relationship corresponding to the information related to the HARQ timing relationship. For example, the UE according to the received one of the effective indication signaling, or a few ratios The bit is used to determine whether to use the HARQ timing relationship. The field may be 1 bit, or may be 2 bits or other bits. The system may specify that the field is used to indicate that the HARQ timing relationship corresponding to the information related to the HARQ timing relationship is valid or not valid, for example, 1 bit. In the case, the status is '0, does not take effect, and the status is "1" for the valid.

In this manner, if the eNB does not use the HARQ timing relationship corresponding to the information related to the HARQ timing relationship, the effective indication signaling sent by the eNB to the UE indicates that the UE does not The HARQ timing relationship corresponding to the information related to the HARQ timing relationship is used. If the eNB uses the HARQ timing relationship corresponding to the information related to the HARQ timing relationship, the Nth effective indication signaling sent by the eNB to the UE indicates the UE In the HARQ timing relationship corresponding to the information related to the HARQ timing relationship, the eNB and the UE use the HARQ timing relationship corresponding to the information related to the HARQ timing relationship, in which case the eNB When the Nth effective indication signaling is sent, the HARQ timing relationship corresponding to the information related to the HARQ timing relationship is used, and the UE receives the Nth effective indication signaling. The HARQ timing relationship corresponding to the information related to the HARQ timing relationship is used; however, since the effective indication signaling is physical layer multicast signaling, physical layer broadcast signaling, or MAC signaling, etc. The signaling is physical layer signaling and MAC signaling, which can ensure that the UE can receive the signaling securely, which ensures that the eNB and the UE both use the information related to the HARQ timing relationship. The HARQ timing relationship, at the same time, the signaling is small, does not carry many parameters like the RRC reconfiguration message, the UE can receive the signaling very quickly, which guarantees the eNB and the The time difference between the HARQ timing relationships corresponding to the information used by the UE and the HARQ timing relationship is small and can be ignored.

Optionally, if the RRC reconfiguration message carries the uplink reference configuration information and the downlink reference configuration information, the HARQ timing relationship corresponding to the information related to the HARQ timing relationship is the uplink reference configuration information, and the downlink reference configuration The HARQ timing relationship corresponding to the uplink and downlink reference configuration given in the information; if the RRC reconfiguration message carries the e lMTA function off information, the HARQ timing relationship corresponding to the information related to the HARQ timing relationship is S IB1 (System Informa ti on B l oke 1, system information - block 1) The HARQ timing relationship corresponding to the TDD 酉匕匕 ; ; ; ; ; ; ; ; ; ; ; ; ; ; ; ; ; ; ; RRC RRC RRC RRC RRC The HARQ timing relationship corresponding to the information related to the HARQ timing relationship is the HARQ timing relationship corresponding to the uplink and downlink reference configuration given by the RRC reconfiguration message. An embodiment of the present invention provides a method for implementing a hybrid automatic retransmission timing relationship, where an execution entity is an eNB. As shown in FIG. 2, the method includes the following steps:

The RRC reconfiguration message is sent to the UE, where the RRC reconfiguration message carries the information related to the HARQ timing relationship, and the information related to the HARQ timing relationship includes the following at least A type of information: uplink reference configuration information, downlink reference configuration information, e lMTA function shutdown information, and e lMTA function enable information. The eNB sends an RRC reconfiguration message to the UE, where the RRC reconfiguration message carries at least one of the information related to the HARQ timing relationship, and the information related to the HARQ timing relationship mainly refers to the uplink reference configuration information, and the downlink reference Configuration information, e lMTA function shutdown information and e lMTA function enable information.

2 02. Send the effective indication signaling to the UE, where the effective indication signaling includes: physical layer multicast signaling, physical layer broadcast signaling, or medium access control MAC signaling; where the effective indication signaling is And indicating whether the UE uses the HARQ timing relationship corresponding to the information related to the HARQ timing relationship. After the eNB sends the RRC reconfiguration message to the UE, it sends the indication signaling to the UE. The effective indication signaling may be physical layer multicast signaling, or physical layer broadcast signaling, or MAC ( Med ia Acce Ss Con t ro l , Media Access Control) Signaling. For example, the physical layer multicast signaling or the physical layer broadcast signaling may be UE group common PDCCH signaling (UE-G roup-common PDCCH) signaling. The validation indication signaling indicates whether the UE uses the HARQ timing relationship corresponding to the information related to the HARQ timing relationship. Optionally, the effective indication signaling indicates that the UE uses the HARQ timing relationship corresponding to the information related to the HARQ timing relationship in two ways:

The method is as follows: The effective indication signaling is used to indicate that the UE uses the HARQ timing relationship corresponding to the information related to the HARQ timing relationship. In this manner, when the eNB sends the effective indication signaling, the eNB uses the HARQ timing relationship corresponding to the information related to the HARQ timing relationship. Another mode: the content in the effective indication signaling indicates whether the UE uses the HARQ timing relationship corresponding to the information related to the HARQ timing relationship. For example, when the information related to the HARQ timing relationship includes an uplink reference configuration letter Information, the downlink reference configuration information, the e lMTA function shutdown information, and the e lMTA function enable information: one field or several bits in the effective indication signaling sent by the eNB, to determine whether to use the The HARQ timing relationship corresponding to the information related to the HARQ timing relationship. The field may be 1 bit, or may be 2 bits or other bits. The system may specify that the field is used to indicate that the HARQ timing relationship corresponding to the information related to the HARQ timing relationship is valid or not valid. Or the information related to the HARQ timing relationship includes at least two types of information of the uplink reference configuration information, the downlink reference configuration information, the e lMTA function shutdown information, and the e lMTA function enable information: the Nth sent by the eNB to the UE The effective indication signaling may indicate which one or which of the information related to the HARQ timing relationship is valid. For example, in the case that the information related to the HARQ timing relationship includes the uplink reference configuration information, the downlink reference configuration information, the e lMTA function shutdown information, and the e lMTA function enable information, the Nth effective indication signaling carries 4 The bit information may be specified when the 4-bit information is 1 1 01, and the downlink reference configuration information, the downlink reference configuration information, and the e lMTA function enable information are valid, and the UE uses the uplink reference configuration information and the downlink reference configuration. The HARQ timing relationship corresponding to the information.

The effective indication signaling sent by the eNB to the UE may determine whether the UE uses the HARQ timing relationship corresponding to the information related to the HARQ timing relationship, so the eNBA sends the effective indication signaling simultaneously. It is determined whether or not the HARQ timing relationship corresponding to the information related to the HARQ timing relationship is used. If the HARQ timing relationship corresponding to the information related to the HARQ timing relationship is used, the effective indication signaling sent by the eNB to the UE may be instructed by the UE to use the information related to the HARQ timing relationship. The HARQ timing relationship, if the HARQ timing relationship corresponding to the information related to the HARQ timing relationship is not used, the Nth effective indication signaling sent by the eNB to the UE indicates that the UE does not use the The HARQ timing relationship corresponding to the information related to the HARQ timing relationship is described. The effective indication signaling is physical layer multicast signaling, physical layer broadcast signaling, or MAC signaling, etc.; the signaling is physical layer signaling and MAC signaling, and the UE can be guaranteed. The signaling can be received securely, which ensures that both the eNB and the UE use the HARQ timing relationship corresponding to the information related to the HARQ timing relationship, and the signaling is small, unlike the RRC. The configuration message carries many parameters, and the UE can receive the signaling quickly, which ensures that the eNB and the UE use the HARQ timing relationship. The time difference between the HARQ timing relationships corresponding to the closed information is small and can be ignored. Therefore, compared with the prior art, when the RRC reconfiguration message is received, the method provided by the present invention indicates that the eNB and the UE use the matched HARQ timing relationship by using the effective indication signaling to be effective. Improve user experience and increase system capacity.

Embodiment 2: An embodiment of the present invention provides a method for implementing a hybrid automatic retransmission timing relationship. As shown in FIG. 3, the method includes the following steps:

301. The eNB sends an RRC reconfiguration message to the UE.

302. The UE receives an RRC reconfiguration message sent by the eNB. The RRC reconfiguration message includes at least one of the following information related to the HARQ timing relationship: uplink reference configuration information, downlink reference configuration information, e lMTA function off information, and e lMTA function enable information. After the UE receives the RRC reconfiguration message, the information related to the HARQ timing relationship in the RRC reconfiguration message, that is, the uplink reference configuration information, the downlink reference configuration information, the e lMTA function shutdown information, and the e lMTA function enable information does not take effect immediately, the UE The original HARQ timing relationship is still used.

303. The eNB determines whether to use the HARQ timing relationship corresponding to the information related to the HARQ timing relationship, and sends the effective indication signaling to the UE, where the effective indication signaling includes: physical layer multicast signaling, Or physical layer broadcast signaling, or MAC signaling. After the eNB sends an RRC reconfiguration message to the UE, the effective indication signaling sent to the UE may be physical layer multicast signaling, physical layer broadcast signaling, or MAC. Signaling. For example, the physical layer multicast signaling or the physical layer broadcast signaling may be a UE group common PDCCH signaling. Here, the moment when the effective indication signaling is sent may be specified by the LTE TDD system or given by the standard, or the eNB may send a signaling to the UE.

The validation indication signaling indicates whether the UE uses the HARQ timing relationship corresponding to the information related to the HARQ timing relationship. Optionally, the effective indication signaling indicates that the UE uses the HARQ timing relationship corresponding to the information related to the HARQ timing relationship in two ways:

One mode: the effective indication signaling is used to indicate that the UE uses the HARQ and the HARQ The HARQ timing relationship corresponding to the time-related information. In this manner, when the eNB sends the Nth effective indication signaling, the eNB uses the HARQ timing relationship corresponding to the information related to the HARQ timing relationship. Another mode: the content in the effective indication signaling indicates whether the UE uses the HARQ timing relationship corresponding to the information related to the HARQ timing relationship. For example, one of the effective indication signalings is used to indicate whether the UE uses the HARQ timing relationship corresponding to the information related to the HARQ timing relationship; or one of the effective indication signalings The state of the multiple bits is used to indicate whether the UE uses the HARQ timing relationship corresponding to the information related to the HARQ timing relationship; or the scrambling code in the effective indication signaling is used to indicate whether the UE is The HARQ timing relationship corresponding to the information related to the HARQ timing relationship is used. Or, in the case that the information related to the HARQ timing relationship includes the uplink reference configuration information, the downlink reference configuration information, the e lMTA function shutdown information, and the e lMTA function enable information, the effective indication The information of one or more bits in the signaling is the same as or different from the information of the one or more bits in the effective indication signaling sent before being sent to the RRC reconfiguration message, indicating Whether the UE uses the HARQ timing relationship corresponding to the information related to the HARQ timing relationship; or the information of one or more bits in the effective indication signaling, by setting the effective indication with the previous one The information of the bits in the signaling is the same or different, and indicates whether the UE uses the HARQ timing relationship corresponding to the information related to the HARQ timing relationship. Or, for example, the information related to the HARQ timing relationship includes at least two types of uplink reference configuration information, downlink reference configuration information e lMTA function shutdown information, and e lMTA function enable information: Determining the effective indication signaling, determining whether to use the HARQ timing relationship corresponding to the information related to the HARQ timing relationship, including: a state of one or more bits in the effective indication signaling, used to indicate the The UE uses the HARQ timing relationship corresponding to at least one of the information related to the HARQ timing relationship. Optionally, the Nth effective indication signaling sent by the eNB indicates whether the UE uses the HARQ timing relationship corresponding to the information related to the HARQ timing relationship, where the N is an integer greater than 0. The N may be specified by the LTE TDD system or given by the standard, or may be sent by the eNB to the UE. The UE determines, according to the received indication signaling, whether to use the HARQ timing relationship corresponding to the information related to the HARQ timing relationship. And the information related to the HARQ timing relationship includes the information of the uplink reference configuration information, the downlink reference configuration information, the e lMTA function shutdown information, and the e lMTA function enable information: optionally, corresponding to the effective indication in step 303 In a plurality of cases of signaling, the UE determines, according to the received Nth effective indication signaling, whether to use the HARQ timing relationship corresponding to the information related to the HARQ timing relationship in two ways:

One mode: the UE, when receiving the effective indication signaling, determines a HARQ timing relationship corresponding to the information related to the HARQ timing relationship. In this manner, when the eNB sends the effective indication signaling, the eNB uses the HARQ timing relationship corresponding to the information related to the HARQ timing relationship. Alternatively, the UE may determine, according to the content in the received indication signaling, whether to use the HARQ timing relationship corresponding to the information related to the HARQ timing relationship.

For example, the UE may determine, according to one of the received effective indication signalings, whether to use the HARQ timing relationship corresponding to the information related to the HARQ timing relationship. The field may be 1 bit, or may be 2 bits or other bits. For example, the field is 4 bits, and when the 4 bits of the field are 111 1 , the RRC reconfiguration message and the HARQ timing are indicated. The relationship-related information is valid, and the HARQ timing relationship corresponding to the information related to the HARQ timing relationship is used. When the 4-bit of the field is 0000, the information related to the HARQ timing relationship in the RRC reconfiguration message is indicated. Does not take effect, uses the original HARQ timing relationship.

Alternatively, the UE may determine, according to the status of one or more bits in the received indication signaling, whether to use the HARQ timing relationship corresponding to the information related to the HARQ timing relationship. For example, the effective indication signaling has 3 bits, which is used to indicate which subframes can monitor the PDCCH or the ePDCCH. The 3 bits have 8 states, 7 states are used to indicate which uplink and downlink configuration, and the uplink and downlink configurations are 7 uplink and downlink configurations of Table 1, thereby deciding which subframes can monitor the PDCCH or ePDCCH, and remaining The first state is used to specify that the information related to the HARQ timing relationship in the RRC reconfiguration message is valid, and the HARQ timing relationship corresponding to the information related to the HARQ timing relationship is used. Or determining, according to the received scrambling code in the effective indication signaling, whether to use the HARQ timing relationship corresponding to the information related to the HARQ timing relationship. The CRC (Cyclic Redundancy Check) is scrambled on the CRC (Cyclic Redundancy Check), and the specific scrambling code is used to take effect. The specific scrambling code is not valid. For example, the scrambling code 0000000000000000 represents that the information related to the HARQ timing relationship in the RRC reconfiguration message is valid, and the UE determines the HARQ timing relationship corresponding to the information related to the HARQ timing relationship. The scrambling code 11111 11111 11111 1 represents that the information related to the HARQ timing relationship in the RRC reconfiguration message is not valid, and determines that the HARQ timing relationship corresponding to the information related to the HARQ timing relationship is not used.

Or the base station may send two effective indication signalings to the UE, and the UE may be configured according to whether the information of one bit in the received indication signaling is related to the previous one of the effective indication signaling. The information of the bits is the same, and it is determined whether to use the HARQ timing relationship corresponding to the information related to the HARQ timing relationship. For example, the information of the bit may be changed to indicate that the information related to the HARQ timing relationship in the RRC reconfiguration message is valid, and the UE determines the HARQ timing corresponding to the information related to the HARQ timing relationship. relationship. The information of the bit does not change, indicating that the information related to the HARQ timing relationship in the RRC reconfiguration message is not valid, and determining that the HARQ timing relationship corresponding to the information related to the HARQ timing relationship is not used. For example, the information of one bit in the effective indication signaling refers to actual configuration domain information, and the actual configuration in the N-1th effective indication signaling received by the UE in the subframe n The domain information is represented as configuration 1. In the subframes n+k1, k1 > 0, the actual configuration domain information in the Nth effective indication signaling received by the UE is represented as configuration 2, that is, the bit If the information changes, it indicates that the information related to HARQ in the RRC reconfiguration message is valid, and the UE uses the HARQ timing relationship corresponding to the information related to the HARQ timing relationship.

Alternatively, the UE may, according to the received information of one or more bits in the effective indication signaling, the one or the effective indication signaling received before receiving the RRC reconfiguration message. Whether the information of the plurality of bits is the same, determining whether to use the HARQ timing relationship corresponding to the information related to the HARQ timing relationship. For example, the information of the bit may be changed to indicate that the information related to the HARQ timing relationship in the RRC reconfiguration message is valid, and the UE determines the HARQ timing corresponding to the information related to the HARQ timing relationship. relationship. The information of the bit does not change, indicating that the RRC reconfiguration is cancelled. The information related to the HARQ timing relationship in the information does not take effect, and it is determined that the HARQ timing relationship corresponding to the information related to the HARQ timing relationship is not used. For example, the information of one bit in the effective indication signaling refers to the actual configuration domain information. In the subframe n, the actual configuration domain information in the effective indication signaling received by the UE is represented as configuration 1. At n+k1, kl>0, the UE receives the RRC reconfiguration message, and in the subframe n+k2, k2>=kl>0, the actual configuration in the first effective indication signaling received by the UE The domain information is represented as configuration 2, that is, the information of the bit changes, and then the information related to the HARQ in the RRC reconfiguration message is valid, and the UE uses the HARQ corresponding to the information related to the HARQ timing relationship. Timing relationship. When the information related to the HARQ timing relationship includes at least two types of information of the uplink reference configuration information, the downlink reference configuration information, the elMTA function shutdown information, and the elMTA function enable information, the UE according to the received indication And determining, by the state of the one or more bits in the signaling, a HARQ timing relationship corresponding to the information related to the HARQ timing relationship corresponding to the at least one of the information related to the HARQ timing relationship. The effective indication signaling sent by the eNB to the UE may indicate which one or which of the information related to the HARQ timing relationship is valid. For example, in the case that the information related to the HARQ timing relationship includes the uplink reference configuration information, the downlink reference configuration information, the elMTA function shutdown information, and the elMTA function enable information, when the Nth effective indication signaling carries 4 bits. The information may be specified when the 4-bit information is 1101, and the downlink reference configuration information, the downlink reference configuration information, and the eMTTA function enable information are valid. In this case, the UE uses the uplink reference configuration information, and the downlink reference configuration information. Corresponding HARQ timing relationship; when the 4-bit information is 1000, the uplink reference configuration information is valid, and the UE uses the HARQ timing relationship corresponding to the uplink reference configuration information; the 4-bit information is 0010. At the same time, the ELMTA function close information is valid, and the UE uses the HARQ timing relationship corresponding to the TDD ratio given by the SIB1. Or, in the case that the information related to the HARQ timing relationship includes the uplink reference configuration information and the downlink reference configuration information, where the 2 bit information is 10, the uplink reference configuration information is valid, and the UE uses And the uplink reference configuration information and the downlink reference configuration information are valid, and the UE uses the uplink reference configuration information and the downlink reference when the 2-bit information is 11 The HARQ timing relationship corresponding to the configuration information. Of course, if it is specified by the LTE TDD system or given by the standard, it can also be given by the eNB. The UE sends a signaling, and the Nth effective indication signaling sent by the eNB indicates whether the UE uses the HARQ timing relationship corresponding to the information related to the HARQ timing relationship, and the UE receives the The Nth effective indication signaling is used to determine whether to use the HARQ timing relationship corresponding to the information related to the HARQ timing relationship. For the specific method, reference may be made to the foregoing content, which is not described in detail herein. Optionally, in the case that the effective indication signaling is the MAC signaling, a special MAC header may be used to notify whether the HARQ timing relationship corresponding to the information related to the HARQ timing relationship is valid.

In the above method, after receiving the effective indication signaling, the UE may determine, according to the Nth effective indication signaling, whether information related to the HARQ timing relationship in the RRC reconfiguration message is valid. That is, it is determined whether to use the HARQ timing relationship corresponding to the information related to the HARQ timing relationship. For example, if the effective indication signaling is received immediately after the receipt of the effective indication signaling, as shown in Table 1, the original uplink reference configuration is configured with the configuration number 0 and the downlink reference configuration configured with the configuration number 5; The frame n receives the RRC reconfiguration message, where the RRC reconfiguration message carries the uplink reference configuration information and the downlink reference configuration information, where the configuration number of the uplink reference configuration in the uplink reference configuration information is 1; and the downlink reference configuration information is downlink. The configuration number of the reference configuration is 2; the UE receives the effective indication signaling in the subframe N+K1, and the UE follows the configuration of the downlink HARQ timing in the subframe N+K1 according to the configuration number 2 in Table 2. The transmission information is transmitted according to the uplink HARQ timing relationship of configuration number 1 in Tables 3 and 4. Optionally, after receiving the Nth effective indication signaling, after K milliseconds, determining whether to use the HARQ timing relationship according to the received Nth effective indication signaling The HARQ timing relationship corresponding to the related information, where the K is greater than or equal to 0, may be specified by the LTE TDD system or given by the standard, or may be sent by the eNB to the UE. For example, if the valid indication signaling is received and then validated after K milliseconds, as shown in Table 1, the configuration number of the original uplink reference configuration is 0 and the configuration of the downlink reference configuration is The RRC reconfiguration message is received by the UE in the subframe n, where the RRC reconfiguration message carries the uplink reference configuration information and the downlink reference configuration information, where the configuration number of the uplink reference configuration in the uplink reference configuration information is 1 ; downlink reference configuration information The configuration of the row reference configuration is 2, and the UE receives the effective indication signaling in the subframe N+K1, and then the UE passes K milliseconds after the subframe N+K1, and then determines according to the effective indication signaling. After the information related to the HARQ timing relationship in the RRC reconfiguration message is valid, according to the downlink HARQ timing relationship with the configuration number 2 in Table 2, according to the uplink HARQ timing relationship with the configuration number 1 in Table 3 and Table 4 Send and receive information. Optionally, starting from a time when the RRC reconfiguration message is received, determining, after the preset buffer time, the RRC reconfiguration message according to the received Nth effective indication signaling. Whether the information related to the HARQ timing relationship is valid, thereby determining whether to use the HARQ timing relationship corresponding to the information related to the HARQ timing relationship. For example, the UE receives the RRC reconfiguration message in the subframe N 2, and receives the Nth effective indication signaling in the N2+M subframe and the following after the preset buffer time given by the timer, that is, the M frame. The HARQ timing relationship corresponding to the information related to the HARQ timing relationship takes effect. The effective indication signaling is physical layer multicast signaling, physical layer broadcast signaling, or MAC signaling, etc.; the signaling is physical layer signaling and MAC signaling, and the UE can be guaranteed. The signaling can be received securely, which ensures that both the eNB and the UE use the HARQ timing relationship corresponding to the information related to the HARQ timing relationship, and the signaling is small, unlike the RRC. The configuration message carries many parameters, and the UE can receive the signaling quickly, which ensures that the eNB and the UE use the time difference between the HARQ timing relationships corresponding to the information related to the HARQ timing relationship. Very small, can be ignored. Therefore, compared with the prior art, when the RRC reconfiguration message is received, the method provided by the present invention indicates that the eNB and the UE use the matched HARQ timing relationship by using the effective indication signaling to be effective. Improve user experience and increase system capacity. Example 3:
