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: Techniques for accessing a wireless communication system are described. A user equipment (UE) sends a random access preamble for system access. The random access preamble may include a random identifier (ID), a channel quality indicator (CQI), etc. The UE may randomly select the random ID or may be assigned this random ID. The UE receives a random access response from a base station. The random access response may include control channel resources (e.g., CQI and PC resources), uplink resources, and/or control information (e.g., timing advance and PC correction) for the UE. The random access response may be sent in two parts using two messages. A first message may be sent on a control channel and may include identification information and possibly other information. A second message may be sent on a shared data channel and may include remaining information for the random access response.

Abstract: Aspects of the present disclosure relate to techniques for activating opportunistic relays. A combination of uplink and downlink pilots may be used to switch on user equipment relays (UeNBs) in an effort to make more accurate measurements in an effort to enable handovers. According to aspects of the present disclosure, a relay may evaluate one or more channel conditions, determine whether or not to transmit downlink reference signals to a UE based on the evaluation, and transmit downlink reference signals to the UE based on the determination. According to aspects, a relay may determine a set of resources reserved for transmission of uplink pilots by UEs, monitor the set of resources to detect transmission of uplink pilots, and report, to an eNB, a power at which the uplink pilots were received.

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.
