Frequency band, transmission node needed to carry out Channel Detection first before being transmitted, in the case of channel idle
Contention access channel.
Because transmission node may at any time be successfully accessed channel, therefore access moment and system subframe side
Boundary may be inconsistent, and first subframe after access can be made to be part subframe, i.e., only take up in a subframe
Partial OFDM (Orthogonal Frequency Division Multiplex, OFDM) symbol
Carry out data transmission.There is the restriction of maximum transmission time on unauthorized carrier wave, i.e. transmission node occupancy is non-
Authorize the resource on carrier wave to exceed maximum transmission time, otherwise need to re-start contention access.
If first subframe in channel access is part subframe, in a burst (burst) most
Latter subframe is likely to as part subframe, wherein, a burst refers to a transmission node is carried out one
Section is continuously transmitted.For first imperfect subframe in a burst, determination is there is presently no optional

If part subframe, in addition it is also necessary to the concrete DwPTS configurations that indicating section subframe is used, to guarantee
Enough correct demodulating datas.Additionally, UE it may also be desirable to know whether base station transmits on unauthorized carrier wave
Demodulated reference signal (Dedicated Reference Signal, DRS), if upload in unauthorized carrier wave
Defeated aperiodic channel state information reference signals (Channel State Information-Reference
Signals, CSI-RS)/channel reference information interferometry (Channel State Information-
Interference Measurement, CSI-IM), and the biography of the burst transmitted on unauthorized carrier wave
The information such as defeated structure.
