Abstract: Techniques are described for wireless communication. One method includes determining a set of uplink (UL) component carriers (CCs) to use for a user equipment (UE). The set of UL CCs may include at least one UL CC in a first radio frequency spectrum band and at least one UL CC in a second radio frequency spectrum band. The method further includes identifying, for a subframe, uplink control information (UCI) due for transmission, the UCI associated with one or more CCs, and limiting available UL CCs for transmission of the UCI to the at least one UL CC in the first radio frequency spectrum band.

Abstract: Systems and methods for uplink transmission scheduling are disclosed. A wireless device may monitor at least two downlink sub-frames for scheduling grants. The wireless device may receive a first uplink scheduling grant in one of the at least two downlink sub-frames for at least a first uplink sub-frame and receive a second uplink scheduling grant in another of the at least two downlink sub-frames for at least the first uplink sub-frame. The wireless device may perform an uplink transmission in the first uplink sub-frame based on one or both of the first uplink scheduling grant and the second uplink scheduling grant. For the uplink transmission, the wireless device may select a most recent uplink scheduling grant or select an uplink scheduling grant received in a downlink sub-frame at least a minimum number of sub-frames before the first uplink sub-frame.

The UE receives synchronization signals and an information block from a first base station. The information block includes information indicating whether the first base station is in a dormant state or an active state.

Abstract: Methods, systems, and devices for wireless communication are described. A user equipment (UE) may establish a concurrent connection with different cells from two base stations. During a certain time period, the UE may be power limited for transmissions to the first base station but not for the second base station. In some cases, the UE may then transmit an SRS to the second base station and drop or reduce the power of an SRS transmission to the first base station. In other cases, the UE may determine that a first cell or a second cell is in a power limited state due to scheduled transmissions for the respective cells. In such cases, the UE may drop a scheduled transmission or scale transmission power of the first and second cells by a common value.

Abstract: Techniques are described for channel access in a radio frequency spectrum band shared by a number of asynchronous operators. One or more clear channel assessment (CCA) procedures may be used to contend for one or more transmission periods in the radio frequency spectrum band. When the contention is won for one or more transmission periods, a determination may be made as to whether the a number of transmission periods for which contention has been won is equal to or greater than a threshold number of consecutive transmission periods. If the number of transmission periods for which contention has been won is at or above the threshold number, occupancy of the radio frequency spectrum band may be relinquished for a period of time, in order to allow another operator to access the radio frequency spectrum band.
