Abstract: A method is provided for transmission control of a user terminal utilizing half-duplex frequency division duplex operation. The method includes defining a transmission qap pattern for at least one user terminal. The transmission gap pattern indicates 1) sub-frames during which the user terminal is to perform uplink transmission, 2) sub-frames during which the user terminal is to expect to perform downlink reception including at least reference symbols for performing downlink tracking, and 3) at least one of a Tx-to-Rx switching sub-frame during which the user terminal is to switch from the uplink transmission to the downlink reception, and a Rx-to-Tx switching sub-frame during which the user terminal is to switch from the downlink reception to the uplink transmission. The transmission qap pattern is provided to the user terminal, and the user terminal is operated according to the transmission qap pattern.

Abstract: Systems, methods, apparatuses, and computer program products for power state transition handling for energy harvesting aware user equipment are provided. For example, a method can include monitoring an energy level and power state of a user equipment. The method can also include determining whether the energy level satisfies a power state transition criterion. The method can further include transitioning from a first power state to a second power state based on the power state transition criterion being determined to be satisfied by the energy level of the user equipment.

Abstract: A method and apparatus may include receiving, by a machine type communication user equipment, parameters for frequency hopping in downlink or uplink. The parameters comprise an “X,” ‘Y,” and “Z” parameters, “X” corresponds to a duration for which the same physical resource blocks are used for transmission. ‘Y” corresponds to a frequency hopping period, and “Z” corresponds to a frequency hopping pattern indication. The method may also include performing frequency hopping in accordance with the parameters.

Abstract: A network device includes at least one processor and at least one memory. The memory stores instructions which, when executed by the processor(s), cause the network device at least to: access ambient IoT device deployment information for ambient IoT devices and user equipment apparatus (UE) deployment information for user equipment apparatuses (UEs); select, based on the ambient IoT device deployment information and the UE deployment information, candidate user equipment apparatuses (candidate UEs), from among the UEs, for providing backscattering service to ambient IoT devices; and iteratively select a subset of UEs, among the candidate UEs, to provide the backscattering service, where the iterative selecting is based at least on, for each iteration, at least one of: respective availability of the plurality of candidate UEs to provide the backscattering service, or at least one criterion relating to respective information in backscattering signals provided by the plurality of ambient IoT devices.
