Problems solved by technology

[0004] However, the specific network topology in the system will cause the motion state of each node to be inconsistent, and the time, power, and frequency offset of the data received by each node from other neighboring nodes will be inconsistent. In the HARQ mechanism, the current receiving node cannot Correctly analyze the ACK / NACK of each neighboring node, increase the complexity and accuracy of the channel estimation of the detection node, and have very high requirements for the terminal data processing capability

Abstract

The embodiment of the invention discloses a hybrid automatic repeat request (HARQ) response method and device, equipment and a medium. The method comprises the following steps: generating at least one piece of HARQ response information according to a receiving result of a data frame sent by a sender; generating a target HARQ frame according to each piece of HARQ response information and at least one effective cyclic shift value and at least one reserved cyclic shift value corresponding to a preset target base sequence; and sending the target HARQ frame to a sender to indicate the sender to detect a signal of a time slot position corresponding to the effective cyclic shift value according to the signal of the time slot position corresponding to the reserved cyclic shift value in the target HARQ frame. According to the embodiment of the invention, the accuracy of HARQ feedback signal detection can be improved, and meanwhile, the channel estimation complexity of HARQ system nodes is prevented from being increased.

Description

technical field [0001] The embodiments of the present invention relate to the field of communication technologies, and in particular, to a hybrid automatic repeat request (HARQ) response method, device, device, and storage medium. Background technique [0002] MESH (Wireless Mesh Network) is a new type of wireless network that is completely different from traditional wireless networks. It is a technology that dynamically establishes new links to connect with other nodes. It has the advantages of self-organizing network, self-repair, multi-hop cascading, and node self-management, which can greatly reduce the cost and complexity of network deployment. Any node in the network can act as an access point and a router at the same time, each node can send and receive signals, and each node can also communicate directly with one or more peer nodes. In the wireless MESH network, it is necessary to consider the guarantee of data transmission reliability during the multi-hop process o...
