1. selection, for a method for the first transport block size passing of protocol Data Unit of wireless chain control layer, is characterized in that, comprises the following steps:

  • Step S102, optional transport block size when the scheduling entity of media access control layer is calculated first biography;

    Step S104, whether the transport block size that judgement is calculated is greater than protocol Data Unit dimension threshold, if be not more than, selects the transport block size calculating as the transport block size passing for head, if be greater than, proceeds to step S106;

    Step S106, described scheduling entity is according to the distribution condition of current wireless resource, whether judgement selects to be greater than the transport block size of described protocol Data Unit dimension threshold, if, select the transport block size calculating as the transport block size passing for head, if not, the transport block size of the transport block size of selecting to be less than described protocol Data Unit dimension threshold for passing for head;

    Wherein, in step S106;

    If user has the business on other higher priority radio bearers, described scheduling entity judgement is given the high-priority service on other radio bearers by allocation of radio resources, selects to be less than the transport block size of described protocol Data Unit dimension threshold;

    And/orIf there is the customer service of other higher priority to need scheduling, described scheduling entity judgement is given other high-priority users business by allocation of radio resources, selects to be less than the transport block size of described protocol Data Unit dimension threshold;

    And/orIf user does not have the business on other higher priority radio bearers, but have the long period do not obtain scheduling lower priority radio bearer on business, business on the lower priority radio bearer that described scheduling entity judgement does not obtain allocation of radio resources to dispatch to the long period, selection is less than the transport block size of described protocol Data Unit dimension threshold;

    And/orIf the channel quality indication situation that described scheduling entity is reported according to relevant user equipment knows that the channel quality of this customer service is higher than the channel quality of other customer services, selection be less than described protocol Data Unit dimension threshold transport block size and allocation of radio resources give other customer service can cause wireless resource utility efficiency low, reduce entire system throughput and performance, judgement does not force to select to be less than the transport block size of described protocol Data Unit threshold size.
