301, subscriber equipment A receives the local public P2M RB parameter of base station broadcast;
Unlike the prior art be, in the LTE of present embodiment system, pre-configured local public P2M RB parameter, this this locality public P2M RB parameter is specially public local P2M RB parameter, this public local P2M RB parameter is used for the send mode of the upstream data of the subscriber equipment in the configurating base station overlay area, the base station is by the public local P2M RB parameter of broadcasting, so that the subscriber equipment in this base station coverage area comprises that subscriber equipment A receives the public local P2M RB parameter of this base station.
Wherein, local public P2M RB parameter (also can be the RB resource), the effect of local public P2M RB parameter is exactly the configuration notification subscriber equipment of the mapping of physical channel that the business of high level is carried out and transmission channel etc. and transformat etc., subscriber equipment carries out the transmission of data according to physical channel and transmission channel and the transformat etc. of this configuration, to satisfy different business demands.Such as, RLC (Radio Link Control in the public P2M RB parameter of this locality, wireless chain control layer) layer can be AM (Acknowledged Mode, affirmation mode) pattern (all data are all wanted feedback acknowledgment) also can be UM (Unacknowledged Mode, Unacknowledged Mode) pattern (data need not feedback acknowledgment), but for the less demanding business of this delay sensitive accuracy of voice, the UM pattern gets final product, but for exigent business of accuracy such as downloads, just need to be the AM pattern.
This this locality public P2M RB parameter comprises following parameter at least:
P2M-RNTI (Point to Multipoint-Radio Network Temporary Identifier, point-to-multipoint-transmission Radio Network Temporary Identifier) is used for this subscriber equipment of scheduling and sends upstream data.
P2M-PUCCH config (P2M-Physical Uplink Control Channel, point-to-multipoint-physical uplink control channel), disposed the ascending control channel of this UE, UE can send CQI at this channel, and the HARQ feedback signaling of downstream data channel.
P2M-CQI (P2M-Channel Quality Indicator, the indication of P2M channel quality) config is used for informing subscriber equipment with what cycle, feeds back the CQI of which frequency range.
