In an LTE system, the UE needs to know the start time of data or control information transmission in the current subframe before receiving data.

The second information may be specifically: a system information block of a type of the Mth system information block that is required to be received by the low complexity UE accessing the cell, and an Mth broadcast that is required to be received by the low complexity UE accessing the cell. Or an information block of a type of multicast information block, a control channel for scheduling the Mth system information block, a control channel for scheduling the Mth broadcast or multicast information block, a paging message, a random access response message, a scheduling paging message One or more of a control channel, a control channel for scheduling a random access response message, a contention resolution message, and a control channel for scheduling a contention resolution message; wherein N and M are both positive integers, and M>N.

Preferably, in the embodiment of the present invention, if the low complexity UE determines the first information by receiving signaling sent by the base station, then:

The signaling is: a system information block of a type of the Nth system information block that is required to be received by the low complexity UE to access the cell, and the second information is: the type of the low complexity UE accessing the cell needs to receive A system information block of the type of M system information blocks.

When the low complexity UE receives the Mth system information block, it needs to determine the OFDM start symbol of the received Mth system information block. If the first information is indicated in the Nth system information block before the Mth system information block, the OFDM start symbol of the Mth system information block may be dynamically adjusted according to the traffic load and/or the cell load, and the resource is optimized. Utilization efficiency.

For example, the base station sends the first information to the low-complexity UE in the MIB, and the low-complexity UE can learn the first information according to the received MIB, so that the second information that is subsequently received can be learned according to the first information (for example, SIB1). The OFDM starts symbol information so that the second information (for example, SIB1) can be correctly received.

Of course, if the base station sends the first information to the low complexity UE in the SIB1, the low complexity UE needs to acquire the SIB1 in order to obtain the first information, which involves how to obtain the low complexity UE. Take the issue of SIB1. For this problem, the technical solution in the embodiment of the present invention may also be adopted. For example, the low complexity UE may first determine the time information of receiving the SIB1 according to the pre-specification of the system or the standard, or the base station may also pass the primary information block to the low complexity UE. The low complexity UE is notified to receive the time information of the SIB1, so that the low complexity UE can receive the SIB1, and can also obtain the first information from the SIB1.

In the embodiment of the present invention, the low complexity UE can be informed of the first information in a systematic or standard predefined manner, and the signaling interaction between the low complexity UE and the base station is avoided. The first information can also be indicated to the low complexity UE by different signaling, which enhances the flexibility of information indication.

The signaling may be a random access response or a control channel for scheduling a random access response, and the second information may be a contention resolution message or a control channel for scheduling a contention resolution message. Alternatively, the signaling may be a competition resolution message or a control channel for scheduling a contention resolution message, and the second information may be downlink data or an enhanced downlink control channel transmitted by the low complexity UE.

The control channel for the contention resolution message or the scheduling contention resolution message is the first proprietary message that the low complexity UE receives before the establishment of the unlimited resource control. In order to increase flexibility, the start symbols of the proprietary messages of different low complexity UEs may be different. Therefore, the first information is carried in the control channel of the random access response or the scheduled random access response before the first proprietary message, which can increase the flexibility of the first proprietary message transmission and optimize the resource utilization efficiency.

Optionally, in the embodiment of the present invention, if the low complexity UE learns the first information by receiving signaling, the first information is indicated by k bits in the signaling, and the k bits are used to indicate the low complexity UE. The orthogonal frequency division multiplexing start symbol of the second information is received and/or whether the base station supports the low complexity UE, and k is a positive integer.

The low complexity UE needs to determine the capabilities of the base station to determine whether the base station supports the low complexity UE. The low complexity UE can determine the OFDM start symbol according to the first information, and can also determine the capability of the base station, thereby determining whether the base station supports the low complexity UE, and the low complexity UE further determines whether the access cell does not access or not. Community. This can avoid blind attempt detection of low complexity UEs, save power consumption of low complexity UEs, and reduce access delay.

Optionally, in the embodiment of the present invention, the first information is indicated by k bits, which may be in the following manners:

The X states in the k bits indicate that the low complexity UE receives the OFDM start symbol of the second information, and the Y states of the k bits indicate that the base station does not support the low complexity UE; or

The X states of the k bits indicate that the low complexity UE receives the OFDM start symbol of the second information, and the Y states of the k bits indicate that the base station does not support the enhanced transmission; or

The X states of the k bits indicate that the low complexity UE receives the OFDM start symbol of the second information, and the Y states of the k bits indicate that the base station does not support the low complexity UE, and the Z states of the k bits indicate that the base station does not Support for enhanced transmission.

Optionally, in the embodiment of the present invention, for example, k=2, X=3, Y=1, or for example, k=2, X=2, Y=1, Z=1, of course, other values may be used. .

In addition, in addition to the indication modes listed above, there may be other indication manners, as long as there are X states in the k bits indicating that the low complexity UE receives the OFDM start symbol of the second information, for the k bits. Other states specifically indicate what information, and the invention is not limited.

The following is a specific example to illustrate how k bits are indicated.

For example, k=2, that is, 2 bits are used to indicate the first information. Then these two bits can form four different states, namely: 00, 01, 10, 11, which can indicate different information.
