    Abstract: Aspects are described for reducing interference in wireless systems. In a first embodiment, an uplink acknowledgment region associated with a macro cell is determined, and an assignment of uplink control resources is restricted to a region within the uplink acknowledgment region. A control signal is then transmitted to user equipment via the assignment of uplink control resources. In another embodiment, control signals are received from wireless terminals, which include desired uplink control signals associated with an access point base station, as well as interfering uplink acknowledgement signals associated with macro cells. The control signals may then be regenerated by cancelling the set of interfering signals from the control signals. The desired uplink control signals are then decoded.

    Abstract: Methods, systems, and devices for wireless communications are described. A user equipment (UE) may identify a payload for inclusion in an uplink transmission. The UE may organize the payload into a code block group (CBG) that includes one or more code blocks (CB). The UE may map each CB of the CBG to a corresponding uplink shared channel resource unit (e.g., a physical uplink shared channel resource unit) of an uplink transmission occasion of the first UE. The uplink transmission occasion may also be shared with one or more additional UEs such that the CBG of the first UE is multiplexed with additional CBGs from the additional UEs. The UE may transmit, to a base station, the uplink transmission including each uplink shared channel resource unit on which the CBG is organized.

    Abstract: Wireless communication devices are adapted to facilitate a random access procedure. According to one example, scheduled entity can transmit a first transmission that is received by a scheduling entity. The first transmission may include a physical random access channel (PRACH) preamble sequence and a first message including information for determining a device-specific network identifier for the scheduled entity. The scheduling entity may transmit a second transmission that is received by the scheduled entity. The second transmission may include information on a physical downlink control channel (PDCCH) addressed to the device-specific network identifier for the scheduled entity, and a second message on a physical downlink shared channel (PDSCH). Other aspects, embodiments, and features are also included.

    Abstract: Sequence selection techniques for Non-Orthogonal Multiple Access (NOMA) are provided. A User Equipment (UE) sends a request to a base station, the request indicating that the UE is to conduct at least one uplink transmission. The UE receives, in response to the request, an indicator of an expected system load, a value of the indicator including a total number of sequences expected to be used at one time for uplink transmissions in the system. The UE detects that at least two different pairs of sequences in a configured set of sequences have different cross correlation values, the sequences in the set configured for scrambling uplink transmissions. The UE selects, in response to the detecting and based on the indicator, at least one sequence with an improved cross correlation with at least one other sequence the at least one sequence and the at least one other sequence to be used for scrambling uplink transmissions within the system.
