When low complex degree UE is when receiving m-th system information block, it is thus necessary to determine that the OFDM primary sign of received m-th system information block.If indicating the first information in the n-th system information block before m-th system information block, the OFDM primary sign of m-th system information block can carry out dynamic adjustment according to traffic load and/or cell load, optimize the utilization efficiency of resource.

Such as, the first information is carried in MIB and is sent to low complex degree UE by base station, low complex degree UE can know the first information with MIB based on the received, so as to according to the first information come know receipt of subsequent the second information (such as SIB1) OFDM primary sign information, so as to be properly received the second information (such as SIB1).

Certainly, if the first information is carried in SIB1 by base station is sent to low complex degree UE, then low complex degree UE is in order to obtain the first information, it is necessary first to obtain SIB1, this relates to low complex degree UE how to obtain The problem of taking SIB1.For the problem, it equally can be using the technical solution in the embodiment of the present invention, such as low complex degree UE can be according to information at the time of the prespecified first determining reception SIB1 of system or standard, or base station can also by Master Information Block to low complex degree UE notify low complex degree UE receive SIB1 at the time of information, low complex degree UE can receive SIB1 in this way, and the first information can be also obtained from SIB1.

In the embodiment of the present invention, both low complex degree UE can be allowed to know the first information by system or the predefined mode of standard, and avoid the Signalling exchange of low complex degree UE and base station.The first information can also be indicated to low complex degree UE by different signalings, enhance the flexibility of information instruction.

Signaling can be the control channel of random access response or scheduling random access response, and the second information can be contention resolution message or the control channel of scheduling contention resolution message.Alternatively, signaling can be contention resolution message or the control channel of scheduling contention resolution message, and the second information can be the downlink data of low complex degree UE transmission or the down control channel of enhancing.

Because contention resolution message or the control channel for dispatching contention resolution message are low complex degree UE received first proprietary message before unlimited resources control is established.In order to improve flexibility, the primary sign of the proprietary message of different low complex degree UE can be different.Therefore the first information is carried in the random access response before first proprietary message or the control channel for dispatching random access response, the flexibility that first proprietary message is sent can be increased, and optimize the utilization efficiency of resource.

Optionally, in the embodiment of the present invention, if low complex degree UE knows the first information by receiving signaling, the k bit indication first information is so used in the signaling, k bit is just used to indicate the orthogonal frequency division multiplexing primary sign of low complex degree UE the second information of reception and/or whether base station supports that low complex degree UE, k are positive integer.

Low complex degree UE it needs to be determined that base station ability, to judge whether base station supports the demand of low complex degree UE.Low complex degree UE according to the first information in while determine OFDM primary sign, can also determine the ability of base station, to judge whether base station supports the demand of low complex degree UE, low complex degree UE and then judge access cell or do not access cell.It is avoided that the blind trial detection of low complex degree UE in this way, save the power consumption of low complex degree UE and reduces access delay.
