Abstract: A method for performing a frequency scan in presence of an adjacent jammer signal is provided. The method can include a wireless communication device determining an occurrence of an acquisition (ACQ) failure on a candidate system in a frequency scan candidate list (FSCL) generated based on a first frequency scan; identifying the candidate system as a jammer signal in response to the ACQ failure; suppressing the jammer signal to derive a jammer suppressed signal; and performing a second frequency scan based at least in part on the jammer suppressed signal.

Abstract: A method for determining whether an acknowledgement received by a user equipment from an external device is a forced acknowledgement. The method including transmitting a set of data stored in an uplink buffer to an external device, receiving an acknowledgement from the external device, determining if the acknowledgement received from the external device was a forced acknowledgement and flushing out an uplink buffer if determined that the acknowledgement was not a forced acknowledgement. The determining the acknowledgement is a forced acknowledgment being based on whether an uplink retransmission collides with one or more scheduled transmission times, a Physical Hybrid-ARQ Indicator Channel (PHICH) falls between gap measurements and an uplink retransmission collides with one of the gap measurements or a TTI bundling retransmission collides with a gap measurement. If the acknowledgement is not a forced acknowledgment, a set of data stored in the uplink buffer is retransmitted to the external device.

Abstract: Adaptive neighboring cell measurement scaling by a wireless user equipment (UE) device. The UE may operate alternately in active and inactive states in a periodic manner according to DRX cycle timing for each of a plurality of DRX cycles. Paging messages may be checked for while in the active state during each DRX cycle. If a paging message is received, it may be decoded using a joint detection technique. The UE may adaptively determine whether or not to perform neighboring cell measurements during at least a subset of the DRX cycles, and perform neighboring cell measurements according to the adaptive determination. The adaptive determination may be based on one or more of joint detection of paging messages, one or more previous cell measurements, or an amount of motion of the UE.

Abstract: Performing cell re-selection by a wireless user equipment (UE) device. A first cell on which to camp may be selected. The UE may camp on the first cell in an idle-mode. The UE may be configured to perform searches for neighboring cells according to an idle-mode timeline while camping on the first cell. The UE may transmit a connection request to the first cell in order to transition the UE from the idle-mode to a connected-mode via the first cell. One or more searches for neighboring cells may be performed according to a connected-mode timeline after transmitting the connection request, in response to transmitting the connection request. The one or more searches may be performed before the UE establishes the connected-mode with the first cell.

Abstract: Methods and apparatus for adjusting adaptive control loop behavior based on, for example measured artifacts of the radio environment. In one embodiment, a Long Term Evolution (LTE) user equipment (UE) adjusts one or more Automatic Gain Control (AGC) loops based on a measured Doppler spread of received signals. Specifically, one or more AGC parameters (e.g., set-point, loop gain, etc.) are selected based on a measured Doppler spread. The one or more AGC parameters are configured to optimize both the AGC headroom (e.g., dynamic range) and the signal to quantization plus noise ratio (SQNR) of the receiver under dynamic wireless fading channels for the detected Doppler.

Abstract: Providing adaptive channel state feedback (CSF) reports in discontinuous reception (DRX) scenarios in a power-efficient manner. The described algorithm may be able to make adaptive decisions to carry over the CSF from previous DRX cycles based on a comparison between an offset at which CSF values are stable and an offset at which a CSF report is to be sent to a base station. If the CSF values are not stable by the time the CSF report is to be sent, a CSF report from a prior DRX cycle may be used. Alternatively, if the CSF value are stable by the time the CSF report is to be sent, a determination may be made to either generate a new CSF report or use a prior CSF report. The latter determination may be made based on various criteria, including channel conditions and DRX cycle length.

Abstract: A wireless communication device (UE) may provide information pertaining to one or more operating capabilities of the UE to LTE and 5G-NR networks. The UE may transmit information to an LTE base station directly, and to a 5G-NR base station directly, or indirectly via the LTE base station. The information may include preferred values corresponding to any number of different operating parameters associated with wireless communications or wireless communication capabilities of the UE in both LTE and 5G-NR networks, informing and/or requesting the LTE and 5G-NR networks to make provisions based on the transmitted information for the wireless communications of the UE on those networks. The UE may thereby provide assistance information to LTE and 5G-NR networks in a multi-radio-access-technology dual-connectivity setting to request the respective networks to adjust certain operating capabilities of the UE in order to alleviate one or more operating issues that may be affecting the UE.

Abstract: Apparatuses, systems, and methods for a wireless device to perform a method including a user equipment device (UE) exchanging communications with a base station to determine one or more scheduling profiles, such as one or more scheduling-power profiles, where a scheduling-power profile may specify one or more parameters associated with UE communication behavior, e.g., one or more constraints on UE communication behavior and/or slot scheduling of UE communications. In addition, the method may include the UE receiving a slot configuration schedule from the base station. The slot configuration schedule may be based on at least one scheduling-power profile of the one or more scheduling-power profiles. Further, the method may include the UE performing communications with the base station based on the at least one scheduling-power profile.

Abstract: Apparatuses, systems, and methods for providing maximum transmit power control when utilizing multiple radio access technologies. For example, a wireless communication device comprising two cellular radios may intend to transmit on the first radio, while concurrently transmitting on the second radio. To ensure compliance with a maximum transmit power limitation, the device may determine an allowed transmit power level of the first radio, representing a difference between the maximum transmit power limitation and the current transmit power level being transmitted by the second radio. The device may also determine a threshold power level for a communication by the first radio. If the allowed transmit power level meets the threshold power level, then the device may transmit the first communication having a power level between the threshold power level and the allowed transmit power level. Otherwise, the device may forego transmission of the first communication.
