Method and apparatus for determining response indication bit

Abstract

The embodiment of the invention discloses a method for determining response indicating bits. The method comprises the following steps: time-frequency logic resources for transmitting downstream data can be divided into continuous time-frequency logic resources and dynamic time-frequency logic resources; when the continuous time-frequency logic resources are used for transmitting the downstream data, according to the continuous time-frequency logic resources and the corresponding response indicating bitmaps, index numbers of response indicating bits corresponding to the downstream data are determined; and when the dynamic time-frequency logic resources are used for transmitting the downstream data, according to downstream resource control signaling messages and continuous time-frequency logic resources and the corresponding response indicating bitmaps, index numbers of response indicating bits corresponding to the downstream data are determined. The embodiment of the invention further provides a device for determining the response indicating bits. By adopting the method and the device for determining the response indicating bits provided by the embodiment of the invention, the method for determining the response indicating bits is more flexible, the cost of signaling messages also becomes smaller, and resources in the response indicating bitmaps can be fully utilized.

Description

technical field [0001] The invention relates to wireless communication technology, in particular to a method for determining a response indication bit. Background technique [0002] Wireless communication systems are generally used to provide communication services including voice and data service transmission, and these systems can be based on different multiple address access technology system. Wherein, in the OFDMA system, the physical resources of the air interface are divided into time-frequency logical resource blocks of different sizes, and different physical channels are distinguished from each other according to the locations of different time-frequency logical resource blocks allocated thereto. The physical time-frequency logical resources occupied by each physical channel need to be allocated and notified to the mobile station (MS) by the forward resource assignment channel, or a fixed physical time-frequency logical resource is assigned to some physical channels...

AI Technical Summary

Problems solved by technology

It can be seen from the above that since only one control signaling is sent within a certain period of time, instead of sending control signaling for each downlink HARQ data packet, it is impossible to determine the corresponding ACK bit for each downlink HARQ data packet

[0010] It can be seen from the above that the method for determining the ACK bit in the prior art is not suitable for the system that applies the above-mentioned downlink HARQ data packet resource continuous assignment technology, so it is not flexible enough, and the signaling overhead is relatively large
