Abstract: A user equipment receives a first measurement setting for synchronization signal detection, and a second measurement setting for radio resource management measurement. The first measurement setting includes a first gap length and a first measurement gap repetition period, and the second measurement setting includes a second gap length and a second measurement gap repetition period. The user equipment uses the first measurement setting to perform synchronization detection. In response to a small cell being detected, the user equipment provides a feedback indication on an indication channel. The user equipment then performs radio resource management measurement according to the second measurement setting.

Abstract: Configuration of various radio systems may have a number of possible benefits. For example, small cell configuration may be useful for interference mitigation. A method, in certain embodiments, can include determining a virtual subframe index for a cell. The method can also include communicating the virtual subframe index for the cell by communicating a time division duplex configuration and a relative subframe offset.

Abstract: A user equipment that supports a first set of beams accumulates transmit power control (TPC) commands to generate an accumulated correction factor during communication between the user equipment and a base station that supports a second set of beams. The user equipment is configured to use a first subset of the first set of beams during the communication and the base station is configured to use a second subset of the second set of beams during the communication. The user equipment detects a change in the first subset or the second subset. The user equipment resets the accumulated correction factor in response to detecting the change. In some cases, the user equipment generates a plurality of correction factors for a corresponding plurality of closed-loop processes. The user equipment resets some or all of the plurality of correction factors in response to detecting the change.

Abstract: Embodiments of the present invention generally relate to enhanced physical downlink control channel (EPDCCH) search space determination. In one embodiment, a base station may identify an index of the current EPDCCH occasion period, each EPDCCH occasion period including a number of subframes, and the subframes being divided to a number of search units. A distribution of EPDCCH candidates corresponding to at least one EPDCCH aggregation level in the EPDCCH occasion period may be determined based on the index of the EPDCCH occasion period and the number of search units in the EPDCCH occasion period. The base station may then select, from the distribution of the EPDCCH candidates, an EPDCCH candidate for transmitting downlink control information (DCI) to a UE.
