For example, the delivery of system information may be divided into broadcasting a limited amount of the system information and using unicast signaling for delivery of the remaining system information. In some aspects, the delivery of a limited amount of system information may involve broadcasting a compressed PLMN ID list (e.g., broadcasting indications of PLMNs). In some aspects, the delivery of a limited amount of system information may involve broadcasting an indication of the version of system information that is valid for a cell. In some aspects, the delivery of a limited amount of system information may involve broadcasting multiple configurations of system information along with indications of each configuration. In some aspects, the delivery of a limited amount of system information may involve broadcasting compressed non-cell-related system information. ## Claims ### Claim 1 A method of communication for an apparatus, comprising: maintaining a mapping between indications and configurations of a first subset of a set of system information; receiving at least one indication; determining, based on the mapping and the received at least one indication, at least one valid configuration of the first subset of system information; receiving a second subset of the set of system information maintaining a mapping between indications and public land mobile networks (PLMNs); receiving at least one other indication; determining, based on the mapping and the received at least one other indication, at least one public land mobile network (PLMN) with which communication can be established; and establishing communication with another apparatus associated with the determined at least one PLMN, wherein the second subset of system information is received from the other apparatus after establishing the communication. ### Claim 2 (depends on 1) The method of claim 1, further comprising: receiving the mapping from a network entity. ### Claim 3 (depends on 1) The method of claim 1, wherein the mapping is preconfigured in the apparatus. ### Claim 4 (depends on 1) The method of claim 1, wherein the at least one indication is received via a physical broadcast channel. ### Claim 5 (depends on 1) The method of claim 1, further comprising: establishing communication with another apparatus according to the at least one valid configuration of the first subset of system information, wherein the second subset of system information is received from the other apparatus after establishing the communication. ### Claim 6 (depends on 1) The method of claim 1, further comprising: determining that system information maintained at the apparatus has changed or has expired; and sending a request for additional system information as a result of the determination. ### Claim 7 (depends on 1) The method of claim 1, further comprising: determining that a physical layer configuration has changed or has expired; and sending a request for additional system information as a result of the determination. ### Claim 8 A method of communication for an apparatus, comprising: maintaining a mapping between indications and configurations of a first subset of a set of system information; receiving at least one indication; determining, based on the mapping and the received at least one indication, at least one valid configuration of the first subset of system information; receiving a second subset of the set of system information maintaining a mapping between indications and public land mobile networks (PLMNs); receiving at least one other indication; determining, based on the mapping and the received at least one other indication, at least one public land mobile network (PLMN) with which communication can be established; and establishing communication with another apparatus associated with the determined at least one PLMN, wherein the second subset of system information is received from the other apparatus after establishing the communication, and wherein the at least one other indication is mapped to at least one physical configuration parameter. ### Claim 9 (depends on 8) The method of claim 8, further comprising: receiving the mapping from a network entity. ### Claim 10 (depends on 8) The method of claim 8, wherein the mapping is preconfigured in the apparatus. ### Claim 11 (depends on 8) The method of claim 8, wherein the at least one indication is received via a physical broadcast channel. ### Claim 12 (depends on 8) The method of claim 8, further comprising: establishing communication with another apparatus according to the at least one valid configuration of the first subset of system information, wherein the second subset of system information is received from the other apparatus after establishing the communication. ### Claim 13 (depends on 8) The method of claim 8, further comprising: determining that system information maintained at the apparatus has changed or has expired; and sending a request for additional system information as a result of the determination. ### Claim 14 (depends on 8) The method of claim 8, further comprising: determining that a physical layer configuration has changed or has expired; and sending a request for additional system information as a result of the determination.
