Abstract: Methods, systems, and devices for wireless communication are described. A base station may employ a multiplexing configuration based on latency and efficiency considerations. The base station may transmit a resource grant, a signal indicating the length of a downlink (DL) transmission time interval (TTI), and a signal indicating the length of a subsequent uplink (UL) TTI to one or more user equipment (UEs). The base station may dynamically select a new multiplexing configuration by, for example, setting the length of an UL TTI to zero or assigning multiple UEs resources in the same DL TTI. Latency may also be reduced by employing block feedback, such as block hybrid automatic repeat request (HARQ) feedback. A UE may determine and transmit HARQ feedback for each transport block (TB) of a set of TBs, which may be based on a time duration of a downlink TTI.

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.

Abstract: Contention-based uplink communications within a wireless communications system are provided in which a user equipment (UE) may transmit data to a base station autonomously, and thereby reduce delay with established procedures for allocating uplink resources to a UE. A base station may allocate contention-based uplink resources from a set of available uplink resources. A UE may determine that data is to be transmitted using contention-based uplink resources, identify available contention-based resources allocated by the base station, and may autonomously transmit the data using the allocated contention-based resources. The contention-based uplink resources may include a subset of available physical uplink shared channel (PUSCH) resources. The contention-based PUSCH resources may include allocated bins, and a UE may select CB-PUSCH resources from one of the bins for transmission of the uplink data.

Abstract: A method, an apparatus, and a computer program product for wireless communication are provided. The apparatus, e.g., base station, determines a plurality of component carriers configured for a user equipment (UE) served by the apparatus. The plurality of component carriers includes a primary component carrier and a secondary component carrier. The primary component carrier may be a time division duplex (TDD) carrier having a same uplink:downlink configuration as a first cell at a neighboring base station, and the secondary component carrier may be a TDD carrier having a different uplink:downlink configuration as a second cell at the neighboring base station. The apparatus exchanges data with the UE according to an effective uplink-downlink subframe partition of the configured component carriers. The effective uplink-downlink subframe partition may be time varying and the apparatus may operate to limit interference due to the different TDD configurations at the serving and neighbor cells.

Abstract: Extended DRX (e-DRX) operation using hyper frame extension signaling are described. The hyper frame extension signaling may extend the system frame number (SFN) range while maintaining backward compatibility for legacy devices not configured to use the extended SFN range. The hyper-SFN extension signaling may include an index to a hyper-SFN transmitted as part of system information different than that used for transmission of the SFN. UEs configured to use the hyper-SFN may effectively use a longer or extended SFN range that includes the legacy SFN range and the hyper-SFN range. The hyper-SFN extension may be used in an extended idle DRX (eI-DRX) mode which may coexist with existing I-DRX mode on the same paging resources. Additionally or alternatively, paging may be differentiated for eI-DRX mode UEs using separate paging occasions or a new paging radio network temporary identifier (RNTI).

Abstract: A method of wireless communication occurs in a frequency band having a first set of resources associated with a first carrier type and a second set of resources associated with a second carrier type. In one configuration, the first carrier type is a NCT (NCT) and the second carrier type is a LCT (LCT). LCT UEs may only receive signals from the second carrier type. However, NCT UEs may receive signals from both the first carrier type and the second carrier type. Therefore, to provide backward compatibility while supporting NCT UEs, an eNodeB may signal support of the first carrier type to a NCT UE while maintaining signaling with LCT UEs.

Abstract: The present disclosure, for example, relates to one or more techniques for scaling the bandwidth of a carrier. Available sub-channels of an unlicensed radio frequency spectrum band may be determined, and the available sub-channels may be included in the carrier. The available sub-channels may be adjacent or non-adjacent sub-channels. The bandwidth of the carrier may be determined according to which sub-channels are included in the carrier. In this way, the bandwidth of the carrier may be scaled according to the available sub-channels in the unlicensed radio frequency spectrum band.
