Abstract: The present disclosure relates to methods and devices for a handover procedure which may include a user equipment (UE), first base station, and a second base station. In one aspect, the UE can receive an indication to handover from the first base station to the second base station. The UE may then establish a connection with the second base station. In another aspect, the UE can maintain a connection with the first base station over a period of time during the handover. The UE can also communicate with the first base station and the second base station during the period of time based on a time division multiplexing (TDM) pattern. The TDM pattern can comprise a pattern of subframes for communicating with the first and second base station. In another aspect, the UE can release the connection with the first base station at the end of the period of time.

Abstract: Certain aspects of the present disclosure generally relate to wireless communications, and more specifically to enhanced paging procedures for devices with limited communications resources, such as machine type communication (MTC) devices and enhanced or evolved MTC (eMTC) devices. An example method generally includes determining a set of subframes corresponding to a paging occasion for the UE to receive a paging message from a base station (BS), determining, within the set of subframes, at least one narrowband region for receiving the paging message, and monitoring for the paging message in the at least one narrowband region within the set of subframes.

Abstract: In a wireless communication system, user equipment (UE) has autonomy provided by one or more set of rules to handle processing during a measurement gap. UE can ignore or use only a portion of the whole measurement gap if not needed. Thereby, an urgent need for remaining tuned to source carrier frequency can be supported, such as utilizing Random Access Channel (RACH) procedure. UE can also choose to tune to a target carrier frequency supporting timely handovers. Depending on the type of processing required (download shared channel (DL-SCH, UL-SCH, TTI bundling, RACH or SR), the UE may store requests and process the measurements during the gap or ignore the gap measurement as if there were no gaps.

Abstract: The disclosure relates to reduced signaling to carry out the linking between new radio (NR) carrier aggregation (CA) band combinations and NR band processing combinations (BPCs), and includes apparatus and methods of receiving, at a modem of a user equipment (UE), a UE configuration from a base station based on UE band combination constraint information, configuring the UE, by a processor of the UE, according to the UE configuration, and performing a communication with the base station, via the modem of the UE, according to the UE configuration. In an implementation, the disclosure includes transmitting the UE band combination constraint information, such as in the form of receiving a total number of layers supported in a CA band combination, and wherein receiving the UE configuration further comprises receiving a CA combination and a BPC configuration in response to the UE band combination constraint information.

Abstract: The present disclosure provides user equipment power consumption and secondary cell (SCell) activation latency reductions in wireless communication systems. For example, a UE may determine that a secondary cell activation condition has been satisfied. The UE may further transition to a secondary cell activated state based on determining that the secondary cell activation condition has been satisfied, the secondary cell activate state corresponding to a dormant SCell state. The UE may operate at least in the dormant SCell state.

Abstract: Certain aspects of the present disclosure relate to methods and apparatus for coordinating UE capabilities across RATs. In some cases, a UE may provide an indication of one or more first sets of capabilities of the UE to operate in a first RAT network that are compatible with one or more second sets of capabilities of the UE to operate in a second RAT network. Indicating the sets of capabilities may require less signaling overhead than explicitly signaling all possible combinations of capabililites.

Abstract: Aspects of the present disclosure provide techniques and apparatus for user equipment initiated handover. Certain aspects include a method for wireless communications by a user equipment (UE) including determining a first signal metric between the UE and a first base station, while the UE has a connection established with the first base station. The method further includes determining a second signal metric between the UE and a second base station, while the UE does not have a connection established with the second base station. The method further includes determining that the second signal metric is stronger than the first signal metric. The method further includes declaring a radio link failure with the first base station based on determining that the second signal metric is stronger than the first signal metric. The method further includes establishing a connection with the second base station.

Abstract: Certain aspects of the present disclosure relate to allocating user equipment (UE) processing capability among multiple access nodes. In an aspect, processing capability of a UE may be determined. When the UE is in communication with at least a first access node and a second access node, a first allocation of the UE processing capability for the first access node or a second allocation of the UE processing capability for the second access node may be determined. Resources may be assigned for the UE based at least in part on the first allocation or the second allocation. In an aspect, the first access node and the second access node may negotiate to determine the first allocation or the second allocation. In an aspect, the first allocation or the second allocation may be determined based on a previously-configured rule associated with a category of the UE.

Abstract: Aspects of the present disclosure provide techniques that may be used wireless network communication devices to support devices operating with extended discontinuous reception (eDRX). An exemplary method, performed by a BS, generally includes determining at least one paging hyper-frame for paging a user equipment (UE) based on an identification (ID) of the UE, the paging hyper-frame determined from a set of periodically occurring hyper-frames that each span a number of radio frames, receiving a request to page the UE, and transmitting a paging signal to the UE in at least one subframe within a radio frame of the paging hyper-frame. Another exemplary method, performed by a UE, generally includes determining at least one paging hyper-frame for monitoring for a paging signal from a base station (BS) based on an identification (ID) of the UE, the paging hyper-frame determined from a set of periodically occurring hyper-frames that each span a number of radio frames, and monitoring for the paging signal in at least one subframe within a radio frame of the paging hyper-frame.
