Description
Technical field
The present invention relates to wireless communication field, particularly forward direction is shared the signaling channel correlation technique.
Background technology
At present, third generation partner program 2 (3rd Generation Partnership Project 2, abbreviation " 3GPP2 ") physical channel that defines in the standard comprises: the basic broadcast channel of forward direction (ForwardPrimary Broadcast Channel, be called for short " F-PBCCH "), forward direction second broadcast channel (ForwardSecondary Broadcast Channel, be called for short " F-SBCCH "), forward shared control channel (Forwardshared control channel, be called for short " F-SCCH "), forward power control channel (Forward PowerControl Channel, be called for short " F-PCCH "), forward direction acknowledgement channel (Forward AcknowledgementChannel is called for short " F-ACKCH ") etc.
In these channels, F-SCCH belongs to forward control channel, is mainly used in transmission resource management message.Forward control channel (hereinafter to be referred as control channel) is very important channel, also comprises other channels except that F-SCCH, is mainly used in message such as transmission access permission, resource assignation, ACK reply, power control.
Number of resources that control channel takies and positional information are to transmit in F-SBCCH.Per 2 superframes (48 frame) transmission primaries control channel takies among the general F-SBCCH number of resources and positional information, during this period, the resource of distributing to control channel remains unchanged.Because the number of resources that other subchannel takies in the control channel is constant substantially, thus the number of resources that takies of control channel therewith during F-SCCH estimate that the maximum information number that carries is relevant.
The F-SCCH channel is used to transmit message such as access permission, resource assignation.The F-SCCH channel is formed by connecting by a plurality of Message (message).Each Message adopts identical code modulation mode, and uses access terminal MACID (the medium Access Layer sign) scrambling of (Access Terminal is called for short " AT ") of target, transmits after the The whole control channel symbol interweaves.The F-SCCH channel comprises multiple Message, and the length of these Message differs very little.For simplified system, all Message extend to unified length by the mode of zero padding, and connect into the Message sequence.If the Message number that sends is less than system's set-point, then in the trailing zero of Message sequence to reach the length that needs.
The F-SCCH channel comprises forward direction resource assignation signaling, reverse admission confirm signaling, the signaling that each physical frames (time slot) such as broadcast/multi broadcast signaling all may occur.Specifically as shown in table 1, in the Field row different signaling types is arranged, such as " Access Grant " (admission confirm), " RLAM " (backward chaining assignment message), " FLAM " (forward link assignment message) etc.Wherein Access Grant is used for doing the affirmation of reverse access to terminal; FLAM is used for doing the forward channel assignment; RLAM is used for doing the assignment of reverse channel resources.MCW-FLAM1 (many code words forward link assignment message) is used for being multiple-input and multiple-output (Multiple Input Multiple Output, abbreviation " MIMO ") many code words (MultipleCode Word, abbreviation " MCW ") resource assignation under the pattern, packet format (Packet Format is called for short " the PF ") information that wherein comprises ground floor among the MIMO.The PF information that comprises other 3 layers among the MCW-FLAM2.
Table 1
In existing reverse access procedure, after the reverse access probe that terminal sends out is received in the base station, send Access Grant, and simultaneously or send RLAM subsequently to terminal to terminal, be used for the assignment terminal to send the required reverse channel resources of BindUATI.Yet the present inventor finds to send Access Grant and RLAM, can reduce the efficient of signaling greatly, increases system load.
Simultaneously, the present inventor also finds following problem.
Because all signalings all need zero padding to arrive unified length, thereby for those type of messages that are not maximum length, the zone of zero padding has just formed the wasting of resources.
In the assignment signaling of prior art MCW pattern, PF always has 4 layers, and when using more than 1 layer packet format, MCW-FLAM1 is used to transmit the PF of ground floor, and MCW-FLAM2 is used to transmit other PF of 3 layers.When the PF of other 3 layers PF and ground floor was identical, it was unnecessary sending MCW-FLAM2 again, only can reduce the efficient of signaling, increased system load.
When sending FLAM, after system needs terminal to receive FLAM in some cases, feeding back ACK, some situation does not then need, and in addition, needs the time of feeding back ACK possible different yet.Can only dispose by system broadcast channel in current system, flexibility ratio is not enough.
