Abstract: Methods, systems, and devices for wireless communication are described. A wireless device configured for carrier aggregation may communicate using transport blocks (TBs) mapped according to a wideband configuration that includes resources of multiple component carriers (CCs) within a single, low latency transmission time interval (TTI)—e.g., a TTI that has a shorter duration relative to other TTIs used in the same system. The number of CCs, and thus bandwidth, available for mapping each TB may change dynamically based on the configuration of the CCs. For a CC configured with a control region during a given low latency TTI, a TB sent during that low latency TTI may not be mapped to resources of that CC. In other cases, portions of a CC configured with a control region may be used for wideband configurations. Wideband low latency communications may be used on the uplink or downlink communications, or both.

Abstract: Techniques are described for wireless communication. One method includes implementing, at a first node, a first access protocol to contend for access to a wireless communication medium shared by a plurality of nodes; determining whether a triggering event has occurred; and implementing, at the first node, a second access protocol to contend for access to the wireless communication medium based at least in part on a determination that the triggering event has occurred.

Abstract: Resource mapping and coding schemes to handle bursty interference are disclosed that provide for spreading the modulated symbols for one or more transmission code words over more symbols in the time-frequency transmission stream. Certain aspects allow for the modulated symbols to be based on bits from more than one code word. Other aspects also provide for re-mapping code word transmission sequences for re-transmissions based on the number of re-transmissions requested by the receiver. Additional aspects provide for layered coding that uses a lower fixed-size constellation to encode/decode transmissions in a layered manner in order to achieve a larger-size constellation encoding. The layered encoding process allows the transmitter and receiver to use different coding rates for each coding layer. The layered encoding process also allows interference from neighboring cells to be canceled without knowledge of the actual constellation used to code the interfering neighboring signal.

Abstract: Long term evolution (LTE)/LTE-Advanced (LTE-A) deployments with unlicensed spectrum leverage more efficient LTE communication aspects over unlicensed spectrum, such as over WIFI radio access technology. In order to accommodate such communications, various downlink procedures may be modified in order to handle communications between licensed and unlicensed spectrum with LTE/LTE-A deployments with unlicensed spectrum.

Abstract: Systems and methodologies are described that facilitate allocation of uplink acknowledgement (ACK) resources for a wireless communication system. Various aspects described herein facilitate explicit creation and transmission of a bundled assignment of downlink communication resources and uplink resources for ACK transmission, thereby facilitating overhead-efficient ACK allocation for users that can communicate pursuant to a persistent resource assignment without requiring scheduling information from an associated control channel. Additionally, indexing schemes for uplink ACK resources are provided herein to facilitate ACK allocation for systems in which both scheduled and persistent users can communicate at a common transmission time interval (TTI).

Abstract: A method, an apparatus, and a computer program product for wireless communication are provided. The apparatus transitions to a dormant state and transmits a very low duty cycle signal (LDCS) while in the dormant state. The apparatus may transmit an LDCS configuration to a second entity, the second entity being one of an LPN that is not in a dormant state and a macro cell. The apparatus may further monitor for a RACH messages at a predetermined RACH delay after transmitting the LDCS. The apparatus may transition to a DRX/DTX mode. The DRX/DTX mode may be matched to at least one connected UE.

Abstract: Methods, systems, and devices for wireless communication are described. A wireless device may use a sampling rate that is less than a default sampling rate associated with a wireless carrier. The device may operate in a narrowband portion of a system bandwidth, and the sampling rate may be less than that used by devices monitoring the whole bandwidth. Multiple sampling rates may be used so that a portion of signal processing may be associated with one sampling rate and another portion of the signal processing may be associated with another sampling rate. The size of a cyclic prefix (CP) may be adjusted based on the sampling rate to align subframe timing boundaries for signals of different sampling rates. In some cases, each symbol of a signal may include both a CP and a postfix such that the postfix for each symbol overlaps the prefix of the next symbol.
