    Abstract: At least one neighbor cell is identified by a base station by detecting a synchronization signal of the at least one neighbor cell. A received signal power, such as a Reference Signal Received Power (RSRP) or a Reference Signal Received Quality (RSRQ), or a combination thereof, is also measured from the at least one neighbor cell. Identifying information and the received signal power of the at least one neighbor cell is then communicated to a network entity of the wireless network. Information is received from the network entity indicating whether the base station can enable a reconfiguration of the allocation of uplink and downlink subframes used in the cell of the base station. Based on the information received from the network entity, the base station enables a reconfiguration of the allocation of uplink and downlink subframes used in the cell.

    Abstract: Technology to provide conditional physical uplink control channel (PUCCH) resource allocation in time division duplex (TDD) for a hybrid automatic retransmission request-acknowledge (HARQ-ACK) transmission in a subframe n is disclosed. In an example, a user equipment (UE) can include computer circuitry configured to: Receive a downlink control channel within a prior specified subframe, wherein the prior specified subframe occurs in time before the subframe n; recognize a downlink control channel type received within the prior specified subframe is a physical downlink control channel (PDCCH) or an enhanced physical downlink control channel (EPDCCH); determine a PUCCH resource for the HARQ-ACK transmission using a lowest control channel element (CCE) index of the PDCCH when the received downlink control channel type is the PDCCH; and determine the PUCCH resource for the HARQ-ACK transmission using a lowest enhanced CCE (ECCE) index of the EPDCCH when the received downlink control channel type is the EPDCCH.

    Abstract: A system and a method for a mobility measurement in a wireless network comprises determining at a wireless terminal a channel power estimation ES for a carrier signal based on Channel State Information Reference Signals (CSI-RS), and determining at the wireless terminal a noise plus interference I+N for the carrier signal based on a muted CSI-RS. The carrier signal is an additional carrier without the presence of a Cell-specific Reference Signal. In one exemplary embodiment, the periodicity of the CSI-RS is selected to be 1, 2 or 3 subframes.
