Abstract: Techniques are described for wireless communication. One method includes determining, based at least in part on a number of downlink component carriers (CCs) scheduled for a user equipment (UE) during a reporting interval, a number of bits to be included in a physical uplink control channel (PUCCH) acknowledgement/non-acknowledgement (ACK/NAK) payload for the reporting interval; and selecting, based at least in part on the determined number of bits, a format of the PUCCH ACK/NAK payload.

Abstract: Methods, systems, and devices are described for decreasing user plane latency in a wireless communication system. This may include routing a portion of bearer traffic to or from a UE through a local or serving gateway, or within or between base stations, rather than via the core network. In some examples, techniques for selected internet protocol flow ultra-low latency (SIPFULL) for systems in which users may have subscribed to enhanced services may be employed. The network may, for instance, authorize SIPFULL functionalities for UEs per access point name (APN) based on individual services subscribed by the UE to improve overall quality of service (QoS). In some examples, a UEs latency requirements or SIPFULL authorizations may affect mobility operations.

Abstract: Methods, systems, and devices are described for wireless communication. Wireless devices may exchange data using Medium Access Control (MAC) layer units known as transport blocks which may include a number of code blocks (CBs). A receiving device may attempt to decode each CB and send acknowledgement (ACK) and negative-acknowledgment (NACK) feedback to the transmitting device based on the whether each CB was successfully decoded. The receiving device may determine a format from two or more available formats for transmitting the ACK/NACK feedback. The format for the ACK/NACK feedback may be determined based at least in part on a number of CBs received and a number of CBs that have a NACK feedback. ACK/NACK feedback may be provided on an individual CB basis, or for bundles of CBs. The transmitting device may perform blind decoding of the received feedback to determine the ACK/NACK format and CBs that have NACK feedback.

Abstract: A method and apparatus for operating a satellite access network (SAN) of a satellite communication system to schedule communications with a user terminal. In some aspects, the SAN may provision a communication frame, for the user terminal, into a number of forward-link (FL) subframes and a different number of reverse-link (RL) subframes. The SAN then transmits the FL subframes to the user terminal via a forward link of the satellite communication system, and subsequently receives the RL subframes from the user terminal via a reverse link of the satellite communication system.

Abstract: Techniques are described for preempting resource allocations to one or more UEs in the event that delay sensitive data is received. A resource allocation of a number of symbols may be granted to a first user equipment (UE) for first associated data to be transmitted. Subsequently, data may be received for a second UE that is more delay sensitive than the first data. The resource allocation to the first UE may be preempted, and resources allocated to the second UE for the second data within a variable length transmission time interval (TTI) of the resource allocation to the first UE. UEs may monitor for preemption during transmissions to other UEs in order to receive new resource grants associated with the preempted resource grant. Whether a UE monitors transmissions for preemption may be determined based on a quality or service (QoS) of the UE.

Abstract: Described herein are methods, systems, and apparatus for communicating control information over a primary component carrier (PCell). In one example, a method for wireless communication is described that includes communicating using an enhanced component carrier (eCC) on at least a secondary component carrier (SCell) in a carrier aggregation (CA) configuration. The method may also include using a PCell for control information pertaining to communications on the eCC. The control information may be channel state information (CSI) or acknowledgment/negative-acknowledgment (ACK/NACK) feedback information.

Abstract: Multiple data bearers may be configured for a user equipment (UE) for carrier aggregation and may be split among multiple evolved nodeBs (eNBs). The eNBs may be selected to serve the multiple data bearers for the UE based on various criteria such as channel conditions, loading, and the like. Various eNBs may be selected to serve data bearers for UE on a per data bearer basis, so that a particular eNB may be selected to serve each data bearer of the UE. Each data packet for the UE may then be sent via an appropriate data bearer.

Abstract: A method, an apparatus, and a computer readable-medium for wireless communication are provided. The apparatus receives data via a first group of component carriers (CCs) of a plurality of groups of aggregated CCs. The first group of CCs correspond to unlicensed or shared frequencies. The apparatus selects a CC from at least two CCs of the first group of CCs for transmission on a physical uplink control channel (PUCCH). The selection of the CC is based on at least an uplink-transmission clearance status of each of the at least two CCs. The apparatus transmits the PUCCH via the selected CC.

Abstract: Various aspects described herein relate to communicating using dynamic uplink and downlink transmission time interval (TTI) switching in a wireless network. A notification can be received from a network entity of switching a configurable TTI from downlink communications to uplink communications. The configurable TTI can be one of a plurality of TTIs in a frame structure that allows dynamic switching of configurable TTIs between downlink and uplink communications within a frame. Additionally, uplink communications can be transmitted to the network entity during the configurable TTI based at least in part on the notification.
