Abstract: Aspects described herein relate to receiving communications in contention-based radio access technologies (RAT). Communication resources can be activated for monitoring one or more channels related to a contention-based RAT based at least in part on a discontinuous receive (DRX) cycle. The one or more channels related to the contention-based RAT can be monitored in one or more time periods following activating the communication resources to determine whether communications are received from an access network node. An on-duration timer during which the communication resources remain active to receive the communications in the contention-based RAT can be initialized based at least in part on determining that the communications are received from the access network node. The communication resources can be deactivated following expiration of the on-duration timer.

Abstract: Certain aspects of the present disclosure relate to techniques for managing radio link failure recovery for a user equipment (UE) connected to a WWAN and a WLAN. The techniques may include establishing communication with a first radio access technology (RAT) and a second RAT. At least one data flow may be transmitted over each of the first RAT and the second RAT. Determinations may be made as to whether to maintain the at least one data flow over the second RAT when a radio link failure (RLF) is detected at the UE and/or whether to resume the at least one data flow over the second RAT upon RLF recovery. The determinations may be made at the UE, at a network entity in communication with the UE, or some combination thereof.

Abstract: Apparatus, methods, and computer program products providing power savings in Semi-Persistent Scheduling (SPS)-configured Voice over Long Term Evolution (VoLTE) with Connected State Discontinuous Reception (C-DRX) are provided. The apparatus may be a user equipment (UE). The UE receives a packet when the UE is in a persistent scheduling mode. The UE transmits a negative-acknowledgement (NACK) message when the packet is not successfully decoded. The UE refrains from transmitting an acknowledgement (ACK) message when the packet is successfully decoded. The UE may enter a power save state immediately after the packet is successfully decoded. The packet may be addressed to the UE in a unicast message. The packet may be received during an on-duration of a C-DRX cycle. The packet my include VoLTE downlink (DL) traffic. The packet may be received on a physical downlink shared channel (PDSCH).

Abstract: A method, an apparatus, and a computer program product for wireless communication where a macro eNB or similar device may be configured to adjust an ABS configuration that is used for designating ABS subframes are provided to provide a VoLTE service to a UE. The ABS configuration may be adjusted by imposing one or more restrictions, such as alignment of the DRX OnDuration of a UE with some offset to the serving cell non-ABS subframes, and imposing restrictions on the ABS subframe settings at the macro eNB. The method or apparatus may initiate or terminate a wireless communication feature for a UE, and may adjust an ABS configuration based on the wireless communication feature, such that a maximum limit is set on a number of ABS subframes or a minimum limit is set on a number of non-ABS subframes based on the wireless communication feature.

Abstract: The present disclosure describes a method, an apparatus, and a computer-readable medium for a random access channel (RACH) procedure at a user equipment. For example, the method may select a two-step RACH procedure or a four-step RACH procedure at the UE based at least on RACH configuration information received from a base station or the RACH configuration information at the UE. The example method may further include transmitting, from the UE, one or more messages associated with the two-step RACH procedure or the four-step RACH procedure based on the selection.

Abstract: Aspects of the disclosure relate to determining channel state information (CSI) on a component carrier. In an example operation, a device determines a mapping between first time-frequency resources corresponding to a first component carrier (CC) and second time-frequency resources corresponding to a second CC using a prediction algorithm. The device receives, from a base station, a channel state information reference signal (CSI-RS) on the first time-frequency resources corresponding to the first CC and measures first CSI on the first time-frequency resources corresponding to the first CC based on the received CSI-RS. The device further predicts second CSI on the second time-frequency resources corresponding to the second CC based on the measured first CSI using the prediction algorithm. The device then generates a CSI report based on the predicted second CSI and sends the CSI report to the base station.

Abstract: Certain aspects of the present disclosure provide techniques for an extended feature indication in new radio (NR), such as for slice specific extension (SSE). Aspects provide a method that may be performed by a transmitter device, such as a user equipment (UE) or a network node (e.g., a base station (BS)). The method generally includes determining a network node supports an extended feature, the extended feature being associated with an extended feature identifier. The transmitter device transmits a message, the message including the extended feature identifier and an indication that the apparatus is using the extended feature. A receiver device can receive the message and process the message and/or one or more subsequent messages based on the indication that the transmitter device is using the extended feature and the extended feature identifier.

Abstract: Wireless communications systems and methods related to indicating antenna configuration information and neural network information are disclosed. Neural network information may be selected for an encoder side based on an antenna configuration of a first device housing the encoder. This information may be transmitted with the antenna configuration information to a second device, which may jointly train the neural network with the first device. The first device may further transmit one or more weights after the training, which are stored with the antenna configuration information at the second device as well. When a third device with similar antenna configuration as the first device establishes communication with the second device, the second device may transmit neural network information, as well as weights, to the third device. The third device may use this information, instead of default information, to speed up neural network initialization and training.

Abstract: Methods, systems, and devices for wireless communication are described. A user equipment (UE) may receive data from both a source base station and a target base station during handover. For example, the UE may refrain from resetting or reestablishing media access control (MAC) and packet data convergence protocol (PDCP) layer configurations until after a successful access procedure is performed with the target base station. In some cases, a single radio link control (RLC)/PDCP stack may be used during handover procedures. A source base station may, for example, forward data to a target base station after receiving a handover execution message. A UE may identify and resolve any duplicate data sent by both base stations during the transition. Additional signaling may be used (e.g., during the radio resource control (RRC) configuration) to indicate that a UE supports dual link handover.
