The frequency resource newly increased has the primary frequency resource identical time-domain resource with being broadcasted in the first system message.Its In, identical time-domain resource can be the frequency resource newly increased in the time-domain resource broadcasted in the first system message Configuration.

The number of the frequency resource newly increased is n, and its span is 0~N, each 6 physics moneys of frequency resource correspondence Source block.As n=0, the frequency resource without extra Stochastic accessing；As n=1, there is 1 extra frequency resource, work as n=2 When, there are 2 extra frequency resources.To FDD system, the frequency domain position of extra frequency resource is as follows：

Wherein, whereinPRACH first Physical Resource Block is distributed in expression；Expression is matched somebody with somebody by high-level signaling The Physical Resource Block number put；Represent ascending resource block number.

For TDD system, the frequency location of extra frequency resource by n, it is necessary to be set to n=M-1+n, and wherein M is TDD The number of the frequency resource of the sub- frame in indicated in the first system message.

The above-mentioned method for indicating extra frequency resource by the first system message for base station, is described below and uses special letter The method that order, such as dedicated RRC signaling message indicate extra frequency resource, method can be as follows：

The first, the subframe that the extra frequency resource that dedicated RRC signaling is indicated is broadcasted in the first system message In.Specifically, an IE defined in dedicated RRC signaling message indicates whether that extra frequency resource is used to connect at random Enter transmission, if so, frequency resource and extra frequency resource then in the first system message can be used simultaneously.Further , dedicated RRC signaling message can also define the number that a UE indicates extra frequency resource.Include disappearing for above-mentioned two IE Ceasing to be：

Wherein, RACH-ConfigDedicated-v12 defines dedicated RRC signaling and carries out RACH parameter configurations；Enable- Both-prach-ConfigIndex-and-additional carries out the prach configuration indexs and newly-increased prach of existing system Whether configuration index comes into force simultaneously is configured；Prach-ConfigIndex-Additional-v11 configures extra prach Configuration index.

Wherein, original PRACH frequency resources and the frequency mapping corresponding to the PRACH newly increased in the first system message Position is as follows：

N is the newly-increased PRACH frequency resource numbers defined in the first system message or dedicated RRC signaling.

Alternatively it is also possible to only indicate whether extra frequency resource using an IE and have several extra frequencies Resource, extra frequency resource is indicated whether according to this IE value and has several extra frequency resources.Comprising The message of the IE can be：

Alternatively, according to above-mentioned RRC signaling message, user equipment can use extra frequency resource and first simultaneously The frequency resource that system message is indicated, and it is same, and base station side can also only use volume by defining an IE instruction users equipment Outer frequency resource carries out Stochastic accessing.Defined IE is as follows：
