Methods and apparatuses for multiple system information handling
Systems, methods, apparatuses, and computer program products for multiple system information handling are provided. One method includes receiving, by a UE, one or more instances of system information from the network. For example, the system information may be received in one or more SIBs from an eNB. In one example, the instances of system information may include at least one of legacy system information or eMTC system information. The method may further include determining which of the received instances of system information the UE should use.
1. A method, comprising:
receiving, by a user equipment, in one or more system information blocks instances of system information from a network,
wherein the instances of system information comprises legacy system information and enhanced machine-type communication system information; and
determining which of the received instances of system information to use based on signal power and quality thresholds for the user equipment, and radio quality and power measurements, wherein the radio quality and power measurements include reference signal received power and reference signal received quality.
2. The method according to claim 1 , further comprising receiving an indication of a number of system information instances that are broadcasted.
3. The method according to claim 1 , wherein the receiving further comprising receiving the system information for different coverage levels including normal, shallow, or deep coverage.
4. The method according to claim 1 , further comprising receiving scheduling information comprising at least one of number of repetitions, time and frequency related information, power, modulation, coding, or transport block size.
5. An apparatus, comprising:
at least one processor; and
at least one memory including computer program code;
the at least one memory and the computer program code are configured, with the at least one processor, to cause the apparatus at least to
receive, in one or more system information blocks, instances of system information from a network,
wherein the instances of system information comprises legacy system information and enhanced machine-type communication system information; and
determine which of the received instances of system information to use based on signal power and quality thresholds for the apparatus, and radio quality and power measurements, wherein the radio quality and/or power measurements include reference signal received power and reference signal received quality.
6. The apparatus according to claim 5 , wherein the at least one memory and the computer program code are further configured, with the at least one processor, to cause the apparatus at least to receive an indication of a number of system information instances that are broadcasted.
7. The apparatus according to claim 5 , wherein the at least one memory and the computer program code are further configured, with the at least one processor, to cause the apparatus at least to receive the system information for different coverage levels including normal, shallow, or deep coverage.
8. The apparatus according to claim 5 , wherein the at least one memory and the computer program code are further configured, with the least one processor, to cause the apparatus at least to receive scheduling information comprising at least one of number of repetitions, time and frequency related information, power, modulation, coding, or transport block size.
9. An apparatus, comprising:
at least one processor; and
at least one memory including computer program code;
the at least one memory and the computer program code are configured, with the at least one processor, to cause the apparatus at least to
signal system information in one or more system information blocks,
wherein the system information comprises legacy system information and enhanced machine-type communication system information; and
signal, to one or more user equipment, signal power and quality thresholds for the one or more user equipment to determine which of the legacy system information or the enhanced machine-type communication system information to use.
10. The apparatus according to claim 9 , wherein the at least one memory and the computer program code are further configured, with the at least one processor, to cause the apparatus at least to signal system information for different coverage levels.
11. The apparatus according to claim 10 , wherein the at least one memory and the computer program code are further configured, with the at least one processor, to cause the apparatus at least to signal system information block instances for each coverage level including normal, shallow, and deep coverage.
12. The apparatus according to claim 11 , wherein the each coverage level depends on at least one of a distance between the user equipment and the apparatus or received signal power at the user equipment.
13. The apparatus according to claim 9 , wherein the at least one memory and the computer program code are further configured, with the at least one processor, to cause the apparatus at least to signal scheduling information including at least one of number of repetitions, time and frequency related information, power, modulation, coding, or transport block size.
