Abstract:
1. A method for managing wireless communications, comprising: identifying a first decoding candidate and a second decoding candidate from a plurality of decoding candidates for a localized enhanced Physical Downlink Control Channel (EPDCCH) transmission, wherein each decoding candidate of the plurality of decoding candidates is associated with one or more enhanced control channel elements (ECCEs) including a starting ECCE; identifying a first antenna port from a set of antenna ports for the first decoding candidate; identifying a second antenna port from the set of antenna ports for the second decoding candidate, the second antenna port being different from the first antenna port, wherein the identifying the first and second antenna ports is based at least in part on the starting ECCE associated with each decoding candidate, wherein the starting ECCE associated with each decoding candidate is an element of a set comprising a user equipment (UE) specific search space, and wherein the starting ECCE depends upon a UE ID, a subframe index, an ECCE aggregation level, and a random seed; and decoding the localized EPDCCH based at least on the first and second decoding candidates and the identified first and second antenna ports.
