Coverage extension level for coverage limited device
View Patent ↗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.
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.
