Specific embodiment

Exempting to authorize using the transmission technology of authorization frequency spectrum on frequency spectrum, such as the transmission technology that long term evolution standard defines, and And exempt to authorize the biography mode of frequency spectrum using authorization frequency spectrum auxiliary, effectively by the reliability for authorizing frequency spectrum and it can exempt to authorize frequency spectrum Upper bandwidth resources abundant combine, and guarantee lifting system handling capacity while reliability.Specifically, in order to guarantee that LTE is exempting to award The performance of frequency range is weighed, protocol requirement uses LTE transmission technology in unlicensed band by the way of carrier wave polymerization at present, generally makes Carrier wave in authorized spectrum band is main carrier, makes the carrier wave subcarrier in unlicensed band, realizes exempting from for authorized spectrum band auxiliary Authorized spectrum band access way (LAA, Licensed Assisted Access).

This LAA transmission mode and carrier wave aggregation transfer mode defined in LTE protocol are different.Specifically, in LTE In agreement, the subcarrier under carrier wave polymerization methods is respectively positioned on authorized spectrum band, then the resource of subcarrier can by base station into Row control, therefore can guarantee to be transmitted with the frame structure format of protocol definition.And in the transmission of LAA, exempt to award for using The subcarrier that power frequency range is transmitted, need to meet in the world has the usage mode of unlicensed band different regulations.Example Such as, European Frequency Spectrum regulatory agency requires equipment to have LBT function, and whether idle, if idle if first detecting channel before accessing channel It can then be transmitted, if not idle, be needed to wait for until channel idle can just be transmitted.As it can be seen that subcarrier detects channel sky It can be any point-in-time in the radio frames that LTE is defined at the time of not busy, as Figure 1-1, due to carrier aggregation technology It is required that main carrier is aligned with the subframe of subcarrier namely the radio frames start time of secondary carrier needs and main carrier phase Together, will lead in this way secondary carrier detect the time that can be transmitted start (the T0 moment in Fig. 1-1) until it is next immediately This is part radio frames for a period of time radio frames start time.It is not fixed at the time of due to detecting channel idle, The time span of part radio frames is not fixed.Since the time span of part radio frames is not fixed, relevant agreement is not determined In part, radio frames send any information, and realize what function.

Use for part radio frames, general there are two types of schemes, and wherein the first scheme is not send any data, etc. It is retransmited to next radio frames start time；Second scheme is in part radio frames " send some occupy-place sequences, the sequence It is only used for occupying the channel, this channel is avoided to be occupied by other equipment.The shortcomings that the first scheme, is, vacant in this section On time, this idle carrier wave is possible to be seized by other equipment.The shortcomings that second scheme is, the resource of part radio frames Business information can not be sent, so as to cause the wasting of resources.Technical solution provided in an embodiment of the present invention can enable equipment seize While to the part radio frames, then some useful informations are transmitted in the radio frames of part, to promote resource utilization, to keep away Exempt from the wasting of resources.

The technical solution of the present invention is further elaborated in the following with reference to the drawings and specific embodiments.
