Abstract: Uplink power control techniques for ultra low latency in Long Term Evolution (LTE) devices are presented. For example, an example method for transmission power control is described that includes determining that a first uplink transmission and a second uplink transmission are scheduled for transmission during a symbol of a subframe. In an aspect, the first uplink transmission has a first transmission time interval (TTI) and a first transmission power and the second uplink transmission has a second TTI, the second TTI being different from the first TTI, and a second transmission power. Furthermore, the method may include determining that a power limitation condition is met for one or both of the first transmission power or the second transmission power and adjusting one or both of the first transmission power or the second transmission power based on a determination that the power limitation condition is met.

Abstract: Certain aspects relate to methods and apparatus for latency reduction for UEs in a RRC connected mode. During contention-based uplink access by groups of UEs within a subframe, an eNB may decode the received uplink transmission based, at least in part, on the assigned group of resources assigned to the UE and used for transmission. Additional orthogonalization techniques such as reduced TTI size can be used to reduce collisions among different users performing contention-based transmissions. Furthermore, when the eNB fails to successfully decode the uplink transmission, the eNB may identify the UE that sent the uplink transmission based on a detected reference signal and may transmit an uplink assignment to the identified UE.

Abstract: The disclosure provides for control plane measurements in a wireless device. The wireless device may perform, on signals received over an unlicensed spectrum across multiple sub-frames, radio resource management (RRM) measurements of a cell. The wireless device may identify one or both of a first subset of the RRM measurements associated with a first subset of the sub-frames including opportunistic transmissions and a second subset of the RRM measurements associated with a second subset of the sub-frames including guaranteed transmissions. The wireless device may determine one or more RRM measurement values based on one or both of the first subset of the RRM measurements and the second subset of the RRM measurements. The wireless device may similarly perform radio link management (RLM) measurements and determine RLM measurement values based on the first and second subsets. The wireless device may also use timers for uplink transmissions to detect radio link failures.

Abstract: Certain aspects of the present disclosure provide techniques for controlling transmission power in shared radio frequency spectrum (SRFS). According to techniques, devices (e.g., BSs, UEs, etc.) transmitting in SRFS band may win contention to the SRFS band for at least a portion of a radio frame period. For example, the radio frame period may include a plurality of subframe periods. The devices may also transmit a first signal at a first transmit power during a first subframe period of the radio frame period and transmit a second signal at a second transmit power during a second subframe period of the radio frame period. For example, the first transmit power and second transmit power may be controlled based, at least in part, on a power level determined for the radio frame period.
