Abstract

Generally discussed herein are systems, apparatuses, and methods that can provide a coverage enhancement to a coverage limited device. According to an example a method can include repeating a Physical Broadcast Channel (PBCH) data transmission multiple times over multiple sub-frames to a coverage limited Machine Type Communication (MTC) User Equipment (UE), or repeating the PBCH data transmission two or three times within one sub-frame to the coverage limited MTC UE.

Claims

1. An eNodeB comprising;

a transceiver and processing circuitry, the processing circuitry to configure the processing circuitry to;

repeat Physical Broadcast Channel (PBCH) data three times within one sub-frame;

transmit the repeated PBCH data to a coverage limited Machine Type Communication (MTC) User Equipment (UE) in a first transmission in one of sub-frame one, sub-frame two, sub-frame three, sub-frame four, sub-frame six, sub-frame seven, sub-frame eight, or sub-frame nine and the PBCH data including Master Information Block (MIB) data transmitted a first time in symbols two through five of the sub-frame, and the MIB data transmitted second and third times in symbols six through thirteen of the sub-frame,

repeat transmission of the PBCH data to the coverage limited MTC UE multiple times including at least the first transmission at a first time and a second transmission at a second time after the first time, the time between the first time and the second time is less during a time of day that has a lower average UE traffic and the time between the first time and the second time is greater during a time of day that has a higher average UE traffic.

2. The eNodeB of claim 1, further comprising a processor coupled to the transceiver configured to perform a rate matching operation to determine which Resource Elements (REs) of the sub-frame will carry MIB data of the PBCH data.

3. A method performed by an eNodeB comprising:

repeating Physical Broadcast Channel (PBCH) data three times within one sub-frame;

transmitting the repeated PBCH data to a coverage limited Machine Type Communication (MTC) User Equipment (UE) in a first transmission in one of sub-frame one, sub-frame two, sub-frame three, sub-frame four, sub-frame six, sub-frame seven, sub-frame eight, or sub-frame nine, the PBCH data including Master Information Block (MIB) data transmitted a first time in symbols two through five of the sub-frame and the MIB data transmitted second and third times in symbols six through thirteen of the sub-frame, and

repeating transmission of the PBCH data in a second transmission to the coverage limited MTC UE, wherein the first transmission is at a first time and the second transmission is at a second time after the first time, the time between the first time and the second time is less during a time of day that has a lower average UE traffic and the time between the first time and the second time is greater during a time of day that has a higher average UE traffic.

4. The method of claim 3, further comprising rate matching to determine which Resource Elements (REs) of the sub-frame will carry MIB data of the PBCH data.

5. A non-transitory computer readable storage device including instructions stored thereon, which when executed by a eNodeB, configure the eNodeB to:

repeat Physical Broadcast Channel (PBCH) data three times within one sub-frame;

transmit the repeated PBCH data to a coverage limited Machine Type Communication (MTC) User Equipment (UE) in one of sub-frame one, sub-frame two, sub-frame three, sub-frame four, sub-frame six, sub-frame seven, sub-frame eight, or sub-frame nine the PBCH data includes Master Information Block (MIB) data transmitted a first time in symbols two through five of the sub-frame and the MIB data transmitted second and third times in symbols six through thirteen of the sub-frame, and

repeating transmission of the PBCH data in a second transmission to the coverage limited MTC UE, wherein the first transmission is at a first time and the second transmission is at a second time after the first time, wherein the time between the first time and the second time is less during a time of day that has a lower average UE traffic and the time between the first time and the second time is greater during a time of day that has a higher average UE traffic.

6. The storage device of claim 5, further comprising instructions stored thereon, which when executed by the eNodeB, configure the eNodeB to rate match to determine which Resource Elements (REs) of the sub-frame will carry MIB data of the PBCH data.
