Description
Technical Field
The invention relates to the technical field of mobile communication, in particular to a method and a device for realizing repeated ACK/NACK transmission.
Background
Currently, an existing LEE (Long Term Evolution) system is a scheduling-based system on the one hand, that is, a base station allocates time-frequency resources to carry data, and a terminal (UE) receives downlink data or transmits uplink data according to a control command of the base station: for example, for downlink data transmission, the base station configures a downlink Control Channel and downlink data for the terminal, and the terminal first decodes a Physical Downlink Control Channel (PDCCH) Channel, and if there is a downlink Control command for the terminal, demodulates the downlink data transmitted by the base station according to information such as a frequency resource position and Modulation and Coding Scheme (MCS) specified in the Control command.
On the other hand, the LTE system is also based on HARQ (Hybrid Automatic Repeat Request), that is, after receiving the transmitted data, the receiving end sends feedback information ACK/NACK to the sending end according to whether demodulation is correct or not, so as to determine whether the transmission block needs to be retransmitted: for example, downlink data transmission is received and fed back by the terminal, and the base station determines whether to retransmit the downlink data according to downlink feedback information sent by the terminal. In the same cell, because the UE is located at different positions, the channel quality of the UE often differs greatly, so to ensure the reliability of HARQ feedback, an ACK/NACK repetition mechanism (ACK/NACK repetition) is introduced in the LTE system: the repeated ACK/NACK mechanism is configured and released by a high layer, and is not started under the default condition, namely the UE only needs to send uplink feedback to downlink data on one subframe under the default condition; and, the repetition number of the repeated ACK/NACK mechanism is configured by a higher layer, and may be 2, 4, 6 or reserved, where reserved represents a reservation; when the mechanism is started, the UE sends ACK/NACK feedback on a plurality of continuous uplink subframes, and for TDD, the middle may cross a downlink subframe and a special subframe, so that the absolute duration is greater than the repetition times of the repeated ACK/NACK mechanism; meanwhile, during the period of sending feedback, the UE does not send other uplink signaling.
For example, as shown in fig. 1, subframes 1 to 6 are all Uplink subframes, and ACK/NACK is fed back on a PUCCH (Physical Uplink Control Channel); when the system configures the UE to perform 4 times of ACK/NACK retransmission, the first feedback of the UE is performed on the PUCCH1, and the high layer configures the repeated ACK/NACK of the UE to be performed on the PUCCH4 through RRC (Radio Resource Control) signaling, so that the UE has 3 times of ACK/NACK feedback to continue transmission on the PUCCH 4.
However, the LTE system has only one component carrier (component carrier), and thus implementation of the duplicate ACK/NACK mechanism is easy; for the LTE-a (LTE-advanced) system, as shown in fig. 2, since a carrier aggregation (carrier aggregation) technology that can link a plurality of component carriers with different frequencies and conveniently extend a bandwidth is introduced, a plurality of component carriers can be provided, and in such a case that carrier aggregation is adopted, a transmission mode of a repeated ACK/NACK mechanism is not implemented at present.

Detailed Description
The basic idea of the invention is to configure different member carriers for the repeated ACK/NACK transmission of the same UE in an LTE-A system, namely, the UE is made to know the number of sub-frames for performing the repeated ACK/NACK transmission in multiple modes, and the UE is made to know which member carriers are required to perform the repeated ACK/NACK transmission and frequency hopping patterns (hopping patterns) on different member carriers when performing the repeated ACK/NACK transmission, and the UE adopts the frequency hopping patterns to complete the repeated ACK/NACK transmission on the sub-frames of the corresponding member carriers after knowing the parameters, thereby realizing the repeated ACK/NACK transmission mechanism under the condition of carrier aggregation, further enabling the UE to obtain frequency diversity gain, and improving the uplink coverage capability.
The technical solution in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention; it is to be understood that the described embodiments are merely exemplary of the invention, and not restrictive of the full scope of the invention. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.
in step 301, acquiring the number of subframes for repeating ACK/NACK transmission, member carrier information, and a frequency hopping pattern on different member carriers;
in step 302, the frequency hopping pattern is adopted to complete the transmission of repeated ACK/NACK on the sub-frame of the component carrier according to the obtained content;
in the embodiment of the invention, the UE can acquire the number of the sub-frames for repeating ACK/NACK transmission, the member carrier information and the frequency hopping modes on different member carriers in a plurality of ways; for example, the parameters can be obtained by receiving a high-level signaling notification, wherein the number of subframes for repeating ACK/NACK transmission, the member carrier information, and the frequency hopping pattern on different member carriers are indicated by the state information of high-level signaling bits; in addition, after the frequency hopping mode is selected, the base station does not inform the UE of the frequency hopping mode for repeating ACK/NACK transmission, but the UE adopts the fixed frequency hopping mode for repeating ACK/NACK transmission and the like; the following two ways are taken as examples to describe in detail, wherein different physical uplink control channels on different sub-frames of different component carriers when repeating ACK/NACK transmission are taken as examples, but it is easily understood by those skilled in the art that the following ways are not limited thereto:
1) the UE acquires various parameters for repeating ACK/NACK transmission by receiving the notification of the high-level signaling; specifically, the UE receives a notification including the number of subframes for repeated ACK/NACK transmission, member carrier information, and a frequency hopping pattern on different member carriers sent by the base station through a high-level signaling, then determines the number of subframes for repeated ACK/NACK transmission, the member carrier information, and the frequency hopping pattern on different member carriers according to the notification, and determines parameters again according to the notification every time the repeated ACK/NACK transmission is performed; wherein the higher layer signaling may be, but is not limited to, RRC signaling;
it should be noted that, when repeating ACK/NACK transmission is performed, the frequency hopping pattern may be a frequency hopping pattern in which continuous repeated ACK/NACK transmission occupies one component carrier, taking a frequency hopping pattern in which two continuous feedbacks occupy one component carrier as an example, and taking a system configuration UE to perform 6 times of ACK/NACK repetition transmission as an example, as shown in fig. 4, where subframes 1 to 6 are all uplink subframes, and ACK/NACK is fed back on a PUCCH: the first feedback of the UE is performed on the PUCCH1 of the component carrier 1, the first repetition ACK/NACK of the RRC signaling configuration UE is performed on the PUCCH4 of the component carrier 1, the second and third repetition ACK/NACK of the RRC signaling configuration UE is performed on the PUCCH4 of the component carrier 2, and the fourth and fifth repetition ACK/NACK of the RRC signaling configuration UE is performed on the PUCCH4 of the component carrier 3;
of course, another frequency hopping mode may be adopted, that is, each ACK/NACK transmission is performed alternately on different component carriers; other parameters are the same as the above example and are not described again; as shown in fig. 5: wherein, the subframes 1 to 6 are all uplink subframes, and ACK/NACK is fed back on a PUCCH; the first feedback and RRC signaling of the UE configure the UE to perform the third feedback on the PUCCH1 of the component carrier 1, while the first and fourth repeated ACK/NACK transmissions of the RRC signaling configured UE are performed on the PUCCH4 of the component carrier 2, and the second and fifth repeated ACK/NACK transmissions of the RRC signaling configured UE are performed on the PUCCH4 of the component carrier 3.
2) The UE acquires various parameters for repeating ACK/NACK transmission by receiving the notification of the high-level signaling, and after the UE selects the frequency hopping mode, the base station does not notify the UE of the frequency hopping mode for repeating ACK/NACK transmission any more, but the UE adopts the fixed frequency hopping mode for repeating ACK/NACK transmission; specifically, the UE receives a notification which is sent by a base station through a high-level signaling and contains the number of subframes for repeating ACK/NACK transmission, member carrier information and frequency hopping patterns on different member carriers, and then determines the number of the subframes for repeating ACK/NACK transmission, the member carrier information and the frequency hopping patterns on the different member carriers according to the notification; when repeated ACK/NACK transmission needs to be carried out again, a new frequency hopping mode does not need to be received, and the fixed frequency hopping mode is adopted for transmission;
it is also worth noting that in this manner, similar to manner 1) above, the frequency hopping pattern may also be of a different form; for example, when repeating ACK/NACK transmission is performed, the frequency hopping pattern may be a frequency hopping pattern in which continuous repeated ACK/NACK transmission occupies one component carrier, taking a frequency hopping pattern in which two continuous feedbacks occupy one component carrier as an example, and taking a system configuration UE to perform 4 times of ACK/NACK repetition transmission as an example, as shown in fig. 6, where subframes 1 to 6 are all uplink subframes, and ACK/NACK is fed back on a PUCCH; according to the configuration of high-layer signaling, the first feedback of the UE is carried out on the PUCCH1 of the component carrier 1, the first repeated ACK/NACK of the UE configured by RRC signaling is carried out on the PUCCH4 of the component carrier 1, and the remaining 2 times of ACK/NACK feedback of the UE are continuously transmitted on the PUCCH4 of the component carrier 2;
in another frequency hopping mode, ACK/NACK transmission is performed alternately on different member carriers each time, and other parameters are the same as those in the above example and are not described again; as shown in fig. 7, also taking the system configuration UE to perform 4 repeated ACK/NACK transmissions as an example, the first feedback of the UE is performed on PUCCH1 of component carrier 1, the first repeated ACK/NACK of the RRC signaling configuration UE is performed on PUCCH4 of component carrier 2, the second repeated ACK/NACK of the RRC signaling configuration UE is performed on PUCCH4 of component carrier 1, and the third repeated ACK/NACK of the RRC signaling configuration UE is performed on PUCCH4 of component carrier 2;
if a frequency hopping mode fixing mode is adopted in the LTE-A system, the follow-up repeated ACK/NACK transmission of the UE is carried out by adopting the same frequency hopping mode; otherwise, the subsequent UE needs to perform the repeated ACK/NACK transmission according to the frequency hopping pattern notified by the high-level signaling each time, which is not described herein again.
It can be seen that, by adopting the method of the embodiment of the present invention, different member carriers are configured for the repeated ACK/NACK transmission of the same UE in the LTE-a system, and the number of subframes for the repeated ACK/NACK transmission, the member carrier information, and the frequency hopping patterns on different member carriers are notified to the UE, so that the UE completes the repeated ACK/NACK transmission on the subframe of the corresponding member carrier by using the frequency hopping pattern after acquiring the above parameters, thereby implementing the repeated ACK/NACK transmission mechanism under the condition of carrier aggregation, and further enabling the UE to obtain frequency diversity gain, thereby improving the uplink coverage capability.

it should be noted that the obtaining unit 810 further includes: a notification module 813 configured to notify the transmission unit 820 to perform repeated ACK/NACK transmission by using a fixed frequency hopping pattern after the extraction module determines the frequency hopping pattern for performing repeated ACK/NACK transmission.
