Abstract: The described aspects include methods and apparatus for activating a transmitter to communicate in a wireless network. A small cell can determine to activate the transmitter to serve user equipment (UE) in a wireless network. The small cell can then broadcast a portion of a set of broadcast signals in a radio frame and broadcast a remaining portion of the set of broadcast signals along with the portion of the set of broadcast signals in a subsequent radio frame. By refraining from immediately broadcasting all broadcast signals, the small cell can mitigate interference to other small cells. In addition, a UE can determine whether to generate random access channel (RACH) sequences for proximity determination or uplink timing synchronization based on parameters received in a RACH order. Moreover, a small cell with an active transmitter can decode discovery signals from a device to facilitate handover determination.

Abstract: A method, an apparatus, and a computer program product for wireless communication are provided in which mandated retransmission of data packets according to a compressed timeline provide an alternative to TTI bundling. A first data unit is transmitted in a first subframe and automatically retransmitted in one or more non-consecutive subframes before a response to a preceding transmission or retransmission of the first data unit has been processed. The retransmissions are terminated after an acknowledgement is processed. The automatic retransmissions occur periodically with a predetermined number of intervening subframes transmitted before each retransmission of the first data unit.

Abstract: A method for wireless communication may include a mobile entity receiving a timing indicator for a discontinuous reception (DRX) cycle during a DRX mode, and adjusting at least an acknowledgement timing in response to receiving the timing indicator for the DRX cycle. A base station in communication with the mobile entity may provide a timing indicator for a DRX cycle during a DRX mode to the mobile entity, transmit at least one of downlink (DL) data or an uplink (UL) grant indicator to the mobile entity at a first time, and waiting from the first time for a time period indicated by the timing indicator before receiving at least one of an acknowledgement of the DL data or UL data responsive to the UL grant from the mobile entity.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may receive one or more reference signals from a plurality of transmit receive points (TRPs) associated with a network entity. The UE may transmit, to the network entity and based at least in part on the one or more reference signals, a coherent joint transmission (CJT) Type II channel state information (CSI) feedback report. The CJT Type II CSI feedback report may be based at least in part on a two-stage frequency domain (FD) basis reporting irrespective of a quantity of precoding matrix indicator (PMI) subbands. The CJT Type II CSI feedback report may be based at least in part on selecting coefficients from high-priority coefficients and excluding low-priority coefficients irrespective of coefficient strengths associated with the low-priority coefficients. Numerous other aspects are described.

Abstract: An apparatus, such as a base station, may determine channel conditions associated with at least two carriers on which communication with another apparatus is configured. The apparatus may encode a dataset into a set of protocol data units (PDUs) using fountain coding based on the channel conditions. The apparatus may send a first subset of the set of PDUs to the other apparatus on a first carrier of the at least two carriers. The apparatus may send a second subset of the set of PDUs to the other apparatus on a second carrier of the at least two carriers. Another apparatus, such as a user equipment (UE), may receive the set of PDUs from the apparatus over the at least two carriers, and may decode the set of PDUs to obtain a dataset using fountain coding.

Abstract: Methods, systems, and devices for wireless communications are described. A user equipment (UE) may indicate to the network (e.g., a base station that the UE is communicating with) that the UE is transitioning to an energy harvesting mode, and the network may transmit an indication of a radio resource that is configured for the energy harvesting mode. The UE may communicate with the network via the configured radio resource during the energy harvesting mode. The network may transmit one or more parameters that may trigger the UE to enter the energy harvesting mode. The UE may transmit an indication that the UE is transitioning out of the energy harvesting mode to a normal capability mode, or the UE may transmit an indication that the UE is staying in the energy harvesting mode. The network may indicate, to the UE, a radio resource for a normal capability mode.
