Among various possibilities, tags and/or compression may be used. Additionally, techniques for enhanced security and signaling between network devices are disclosed. ## Claims ### Claim 1 A user equipment device (UE), comprising: a radio; and a processor operably coupled to the radio, wherein the processor is configured to cause the UE to: establish communication with a base station of a cellular network; transmit a first capability identifier tag to the base station, wherein the first capability identifier tag comprises a combination of a device hash identifier and a capability hash identifier and is set to a particular value to indicate a request to re-initiate a capability procedure; receive, from the base station, a capability inquiry in response to the first capability identifier tag; transmit a second capability identifier tag, different from the first capability identifier tag, of the UE to the base station, wherein the second capability identifier tag includes an identification associated with a manufacturer of the UE device, wherein the second capability identifier tag relates to capability information for the UE stored at the cellular network; and communicate, with the base station, according to the capability information. ### Claim 2 (depends on 1) The UE of claim 1, wherein the second capability identifier tag of the UE is transmitted in response to the capability inquiry. ### Claim 3 (depends on 1) The UE of claim 1, wherein the capability inquiry comprises an indication of a requested frequency band, wherein the second capability identifier tag is associated with the requested frequency band. ### Claim 4 (depends on 1) The UE of claim 1, wherein the second capability identifier tag is a unique identifier for the capability information. ### Claim 5 (depends on 1) The UE of claim 1, wherein the second capability identifier tag relates to capabilities of the UE for communication on one or more frequency bands and/or combinations of frequency bands. ### Claim 6 (depends on 1) The UE of claim 1, wherein the second capability identifier tag is based in part on a current configuration of the UE. ### Claim 7 (depends on 1) The UE of claim 1, wherein the second capability identifier tag is smaller than the capability information. ### Claim 8 An apparatus, comprising: a processor configured to cause a user equipment device (UE) to: establish communication with a base station of a cellular network; transmit a first capability identifier to the base station, wherein the first capability identifier comprises a combination of a device hash identifier and a capability hash identifier and is set to a particular value to indicate a request to re-initiate a capability procedure; receive, from the base station, a capability inquiry in response to the first capability identifier; transmit a second capability identifier, different from the first capability identifier, of the UE to the base station, wherein the second capability identifier includes an identification associated with a manufacturer of the device, wherein the second capability identifier relates to capability information for the UE stored at the cellular network; and communicate, with the base station, according to the capability information. ### Claim 9 (depends on 8) The apparatus of claim 8, wherein the second capability identifier of the UE is transmitted in response to the capability inquiry. ### Claim 10 (depends on 8) The apparatus of claim 8, wherein the capability inquiry comprises an indication of a requested frequency band, wherein the second capability identifier is associated with the requested frequency band. ### Claim 11 (depends on 8) The apparatus of claim 8, wherein the second capability identifier is a unique identifier for the capability information. ### Claim 12 (depends on 8) The apparatus of claim 8, wherein the second capability identifier relates to capabilities of the UE for communication on one or more frequency bands and/or combinations of frequency bands. ### Claim 13 (depends on 8) The apparatus of claim 8, wherein the second capability identifier is based in part on a current configuration of the UE. ### Claim 14 (depends on 8) The apparatus of claim 8, wherein the second capability identifier is smaller than the capability information. ### Claim 15 An apparatus, comprising: a processor configured to cause a base station of a network to: establish communication with a user equipment device (UE); receive a first capability identifier from the UE, wherein the first capability identifier comprises a combination of a device hash identifier and a capability hash identifier and is set to a particular value indicating a request to re-initiate a capability procedure; transmit, to the UE, a capability inquiry in response to the first capability identifier; receive, from the UE, a second capability identifier of the UE that is different than the first capability identifier, wherein the second capability identifier includes an identification associated with a manufacturer of the device, wherein the second capability identifier relates to capability information for the UE stored at the network; and communicate, with the UE, according to the capability information. ### Claim 16 (depends on 15) The apparatus of claim 15, wherein the second capability identifier of the UE is in response to the capability inquiry. ### Claim 17 (depends on 15) The apparatus of claim 15, wherein the second capability identifier is a unique identifier for the capability information. ### Claim 18 (depends on 15) The apparatus of claim 15, wherein the second capability identifier relates to capabilities of the UE for communication on one or more frequency bands and/or combinations of frequency bands. ### Claim 19 (depends on 15) The apparatus of claim 15, wherein the second capability identifier is based in part on a current configuration of the UE. ### Claim 20 (depends on 15) The apparatus of claim 15, wherein the second capability identifier is smaller than the capability information.
