Abstract
A method of operating a terminal device capable of coverage enhancement in a wireless telecommunication system including receiving a signal from a base station within the wireless telecommunication system, measuring the received signal strength of the received signal, comparing the measured signal strength with at least one threshold value, and selecting a mode of operation of coverage enhancement based on a result of the comparison.
Claims15
A method of operating a terminal device capable of coverage enhancement in a wireless telecommunication system comprising:
- receiving a signal from a base station within the wireless telecommunication system;
- measuring a signal strength of the received signal;
- comparing the measured signal strength with a first threshold value;
- selecting a first mode of coverage enhancement as a selected mode of coverage enhancement when the measured signal strength is greater than the first threshold value;
- not selecting the first mode of coverage enhancement as the selected mode of coverage enhancement and comparing the measured signal strength with a second threshold value when the measured signal strength is less than the first threshold value;
- and
- selecting a second mode of coverage enhancement as the selected mode of coverage enhancement when the measured signal strength is greater than the second threshold value, wherein
- in the first mode of coverage enhancement transmission of a system information block (SIB) for the terminal device is repeated a first number of times,
- in the second mode of coverage enhancement transmission of a SIB for the terminal device is repeated a second number of times, which is greater than the first number of times,
- the terminal device is a reduced-capability terminal device configured to operate in a subset of an entirety of a bandwidth of the wireless telecommunication system,
- the SIB is a SIBx a specifically configured for reception by reduced-capability terminals, and
- existence of the SIBx is identified by an information element included in a SIB previously received by the terminal device.
A terminal device capable of coverage enhancement for use in a wireless telecommunication system wherein the terminal device comprises:
- circuitry configured to
- receive a signal from a base station within the wireless telecommunication system;
- measure a signal strength of the received signal;
- compare the measured signal strength with a first threshold value;
- select a first mode of coverage enhancement as a selected mode of coverage enhancement when the measured signal strength is greater than the first threshold value;
- not select the first mode of coverage enhancement as the selected mode of coverage enhancement and compare the measured signal strength with a second threshold value when the measured signal strength is less than the first threshold value;
- and
- select a second mode of coverage enhancement as the selected mode of coverage enhancement when the measured signal strength is greater than the second threshold value, wherein
- in the first mode of coverage enhancement transmission of a system information block (SIB) for the terminal device is repeated a first number of times,
- in the second mode of coverage enhancement transmission of a SIB for the terminal device is repeated a second number of times, which is greater than the first number of times,
- the terminal device is a reduced-capability terminal device configured to operate in a subset of an entirety of a bandwidth of the wireless telecommunication system,
- the SIB is a SIBx a specifically configured for reception by reduced-capability terminals, and
- existence of the SIBx is identified by an information element included in a SIB previously received by the terminal device.
