A user equipment (UE) may receive network search information related to the accessible bands. In some examples, the UE may receive network search information from a server that has access to the network search information. The UE may receive the network search information directly from the server or through another wireless device. In other examples, a base station may broadcast network search information on an anchor carrier. The UE may tune to a carrier of a first radio access network to receive the network search information and use the network search information to assist connecting to a second radio access network. The network search information may include, for example, a network name or network ID, a technology type, band or channel information, security information or credentials. ## Claims ### Claim 1 A method for wireless communication at a user equipment (UE), comprising: establishing an application layer connection between the UE and a server; receiving, from the server and over the application layer connection, network search information comprising timing information for a radio access network, the network search information based at least in part on a location of the UE; determining, based at least in part on the network search information, a set of available frequencies associated with available radio access networks; selecting one or more frequencies from the set of available frequencies for the UE to scan based at least in part on the determining; scanning the selected one or more frequencies to perform a network search; and connecting to the radio access network based at least in part on the network search. ### Claim 2 (depends on 1) The method of claim 1, wherein the application layer connection is established using an application program interface (API) of the server that is dedicated for UE access to the server. ### Claim 3 (depends on 1) The method of claim 1, further comprising: transmitting, to the server, a request for the network search information, wherein the network search information is received in response to the request. ### Claim 4 (depends on 1) The method of claim 1, wherein scanning the selected one or more frequencies to perform the network search comprises: searching a search space associated with the radio access network using resources indicated by the network search information. ### Claim 5 (depends on 1) The method of claim 1, wherein connecting to the radio access network comprises: receiving a signal comprising system information from a base station; and performing a network acquisition process based at least in part on the received signal. ### Claim 6 (depends on 1) The method of claim 1, wherein the network search information comprises at least one of a set of network identifiers associated with a set of radio access networks including the radio access network, a set of frequency bands associated with a set of radio access networks including the radio access network, a set of channels associated with a set of radio access networks including the radio access network, a radio access technology associated with a set of radio access networks including the radio access network, security information associated with a set of radio access networks including the radio access network, or any combination thereof. ### Claim 7 (depends on 1) The method of claim 1, wherein the network search information comprises an indication of an availability of a set of radio access networks including the radio access network to new associations. ### Claim 8 (depends on 1) The method of claim 1, wherein the network search information comprises sector-sweep timing information, discovery information, or a combination thereof, for a set of radio access networks including the radio access network. ### Claim 9 (depends on 8) The method of claim 8, wherein the sector-sweep timing information is based at least in part on a timing source available to the UE. ### Claim 10 (depends on 1) The method of claim 1, wherein the server comprises a spectrum allocation server (SAS), a coexistence manager, a base station, or any combination thereof. ### Claim 11 An apparatus for wireless communication, comprising: a processor; memory in electronic communication with the processor; and instructions stored in the memory, wherein the instructions are executable by the processor to: establish an application layer connection between a user equipment (UE) and a server; receive, from the server and over the application layer connection, network search information comprising timing information for a radio access network, the network search information based at least in part on a location of a user equipment (UE); determine, based at least in part on the network search information, a set of available frequencies associated with available radio access networks; select one or more frequencies from the set of available frequencies for the UE to scan based at least in part on the determining; scan the selected one or more frequencies to perform a network search; and connect to the radio access network based at least in part on the network search. ### Claim 12 (depends on 11) The apparatus of claim 11, wherein the instructions are further executable by the processor to: transmit, to the server, a request for the network search information, wherein the network search information is received in response to the request. ### Claim 13 (depends on 11) The apparatus of claim 11, wherein the instructions to scan the selected one or more frequencies comprise instructions executable by the processor to: search a search space associated with the radio access network using resources indicated by the network search information. ### Claim 14 (depends on 11) The apparatus of claim 11, wherein the instructions to connect to the radio access network comprise instructions executable by the processor to: receive a signal comprising system information from a base station; and perform a network acquisition process based at least in part on the received signal. ### Claim 15 (depends on 11) The apparatus of claim 11, wherein the network search information comprises at least one of a set of network identifiers associated with a set of radio access networks including the radio access network, a set of frequency bands associated with a set of radio access networks including the radio access network, a set of channels associated with a set of radio access networks including the radio access network, a radio access technology associated with a set of radio access networks including the radio access network, security information associated with a set of radio access networks including the radio access network, or any combination thereof. ### Claim 16 (depends on 11) The apparatus of claim 11, wherein the network search information comprises an indication of an availability of a set of radio access networks including the radio access network to new associations. ### Claim 17 (depends on 11) The apparatus of claim 11, wherein the network search information comprises sector-sweep timing information, discovery information, or a combination thereof, for a set of radio access networks including the radio access network.
