Compressed system information for link budget limited UEs in a radio access network
First Claim
1. A base station, comprising:
- at least one antenna;
at least one radio, wherein the at least one radio is configured to perform cellular communication using at least one radio access technology (RAT); and
one or more processors coupled to the at least one radio;
wherein the base station is configured to;
broadcast first system information blocks (SIBs) encoded using a first coding rate and a first identifier; and
broadcast second SIBs encoded using a second coding rate that is lower than the first coding rate and a second identifier, wherein a compressed SIB type in the second SIBs includes only a portion of the information included in the same non-compressed SIB type in the first SIBs and wherein the second SIBs are usable by a class of user equipment devices (UEs) having a limited link budget to determine access parameters for the base station.

Abstract
Techniques are disclosed relating to broadcasting and receiving system information in a radio access network (RAN). In one embodiment, a base station includes at least one antenna, at least one radio, configured to perform cellular communication using a radio access technology (RAT), and one or more processors coupled to the radio. In this embodiment, the base station is configured to broadcast first system information blocks (SIBs) encoded using a first coding rate and a first identifier. In this embodiment, the base station is also configured to broadcast second SIBs encoded using a second coding rate that is lower than the first coding rate and a second identifier. In this embodiment, the second SIBs include only a portion of the information included in the first SIBs and the second SIBs are usable by user equipment devices (UEs) having a limited link budget to determine access parameters for the base station.

12. An apparatus, comprising:
one or more processing elements configured to; decode compressed SIBs from a broadcast transmission, wherein the broadcast transmission is received from a base station that broadcasts transmissions with both compressed SIBs and non-compressed SIBs, wherein the apparatus is configured not to decode the non-compressed SIBs in at least one mode of operation, and wherein a SIB type in the compressed SIBs includes only a portion of the information included in the same SIB type in the non-compressed SIBs; and initiate communication with the base station, select a cell, or perform cell reselection based on access parameters specified by the decoded compressed SIBs. - View Dependent Claims (13, 14, 15, 16, 17, 18, 19, 20)

21. A method, comprising:
-
a base station broadcasting non-compressed first system information blocks (SIBs) encoded using a first coding rate and a first identifier; and the base station broadcasting compressed second SIBs encoded using a second coding rate that is lower than the first coding rate and a second identifier, wherein a compressed SIB type in the second SIBs includes only a portion of the information included in the same SIB type in the first SIBs and wherein the second SIBs are usable by a class of user equipment devices (UEs) having a limited link budget to determine access parameters for the base station. - View Dependent Claims (22)
