Embodiment Construction

[0031] A subframe structure and a method and device for transmitting a physical hybrid retransmission indication duration provided by an embodiment of the present invention will be described in detail below with reference to the accompanying drawings.

[0032] The subframe structure provided by the embodiment of the present invention includes a control format indication, which is not only used to indicate the state of the physical downlink control channel, but also can be used to indicate the duration of the physical hybrid retransmission indication. The control format indication occupies 2 bits of the subframe, which indicates the combination state of the control format indication and the duration of the physical hybrid retransmission indication. The indication indicates the channel transmission through the physical control format. Wherein, the control format indication indicates that the physical downlink control channel occupies at least one OFDM symbol in the subframe; the...

Abstract

The embodiment of the invention discloses a subframe structure and a method and a device for transmitting physical mixed retransmission indication continuous time, relating to the technical field of communication and aiming to solve the problem that one or two unused states waste null source in a control format indication in the prior art. The subframe structure provided by the embodiment of the invention comprises the control format indication for representing the state of a physical downlink control channel, and further representing the physical mixed retransmission indication continuous time. The method for transmitting the physical mixed retransmission indication continuous time provided by the embodiment of the invention comprises the following steps: obtaining the control format indication with the physical mixed retransmission indication continuous time; and transmitting the control format indication through a physical control format indication channel. Through using the invention, the free control format indication state can be used so as to reduce the cost of physical broadcast channel and signal to further save null sources.

Description

technical field [0001] The present invention relates to the field of communication technology, in particular to a subframe structure and a method and device for transmitting physical hybrid retransmission indication duration.
