Abstract

Embodiments of a user equipment (UE) and Node-B to operate in a wireless communication network using extended evolved absolute radio frequency channel numbers (EARFCN) and evolved Universal Terrestrial Radio Access (E-UTRA) frequency bands are disclosed herein. The UE may comprise transceiver and processing circuitry to receive a multiple frequency band indicators (MFBI) list that includes list elements corresponding to E-UTRA frequency bands on which neighboring LTE cells are operated. The MFBI list corresponds to an entry in the E-UTRA frequency and priority list or the E-UTRA frequency and priority extension list. The number of list elements for E-UTRA frequency and priority information corresponds to a sum of the number of entries in an E-UTRA frequency and priority list and a number of entries in an E-UTRA frequency and priority extension list. Other embodiments are disclosed.

Dependent claims

A User Equipment (UE) supporting multi-band signaling in a network, the UE comprising transceiver and processing circuitry to:

receive, in multiple frequency band indicators (MFBI) signaling, an MFBI list that includes elements that correspond to evolved Universal Terrestrial Radio Access (E-UTRA) frequency bands on which neighboring LTE cells are operated, wherein each element of the MFBI list corresponds to an entry in one of a E-UTRA frequency and priority list and an E-UTRA frequency and priority extension list,
select a value to be used for the corresponding E-UTRA frequency band based on a Multiple E-UTRA frequency info extension list element if the Multiple E-UTRA frequency info extension list element is not set to a first value that indicates that the Multiple E-UTRA frequency extension list element is absent and select a value based on a Multiple E-UTRA frequency into list element otherwise, wherein a total count of elements for E-UTRA frequency and priority equals a sum of a number of entries in the E-UTRA frequency and priority list and a number of entries in the E-UTRA frequency and priority extension list, wherein each entry in the E-UTRA frequency and priority list and the E-UTRA frequency and priority extension list defines an evolved absolute radio frequency channel number (EARFCN) value and a priority value for the respective EARFCN, and
connect to a neighboring LTE cell using information in an element of the MFBI list.

A non-transitory computer-readable storage medium that stores instructions for execution by one or more processors to perform operations for supporting multi-band signaling in a network, the operations to configure the one or more processors to:

receive, in multiple frequency band indicators (MFBI) signaling, an MFBI list that includes elements that correspond to evolved Universal Terrestrial Radio Access (E-UTRA) frequency bands on which neighboring LTE cells are operated, wherein each element of the MFBI list corresponds to an entry in one of the E-UTRA frequency and priority list and the E-UTRA frequency and priority extension list, and
select a value to be used for the corresponding E-UTRA frequency band based on a Multiple E-UTRA frequency info extension list element if the Multiple E-UTRA frequency info extension list element is not set to a first value that indicates that the Multiple E-UTRA frequency info extension list element is absent and select a value based on a Multiple E-UTRA frequency info list element otherwise, wherein a total count of elements for E-UTRA frequency and priority equals a sum of a number of entries in the E-UTRA frequency and priority list and a number of entries in the E-UTRA frequency and priority extension list, wherein each entry in the E-UTRA frequency and priority list and the E-UTRA frequency and priority extension list defines an evolved absolute radio frequency channel number (EARFCN) value and a priority value for the respective EARFCN.
