Abstract: Aspects of the present disclosure provide techniques and apparatus for enhanced control channel element (ECCE) based physical downlink shared channel (PDSCH) resource allocation for long-term evolution (LTE). A method is provided for wireless communications by a user equipment (UE). The method generally includes determining resources assigned for a data channel, based on a resource granularity associated with a control channel and processing the data channel transmissions in a subframe based on the determination. The data channel may comprise a PDSCH. According to certain aspects, the UE may receive downlink control information (DCI) having a number of bits indicating VRBs assigned for PDSCH. Each VRB may include ECCEs from the same or different enhanced resource element group (EREG). ECCEs may span multiple PRB pairs or the same PRB pair. The UE may perform rate matching around enhanced physical downlink control channel (EPDCCH) overlapping assigned PDSCH resources.

Abstract: An apparatus determines a transmission power of a signal transmitted by a user equipment (UE) in a cell that is identified by a virtual cell identifier. The apparatus generates a power control command based on the determined signal power, and transmits the power control command to a plurality of UEs. Subsequent to transmission of the power control command, the apparatus receives a plurality of transmissions from the plurality of UEs. Some of the transmissions have different transmission powers. The different transmission powers of the signals transmitted by the UEs are due to the power control command and a predefined power offset associated with each respective UE.

Abstract: Methods, systems, and devices for wireless communications are described. In one aspect, the described techniques provide for identifying interference signals on multiple layers or resources and determining whether the interference signals transmitted on a particular layer or resource were precoded using linear precoding (LP) or NLP. In this aspect, a receiving device may equalize signals received from a transmitting device (e.g., filter out interference signals) based on determining whether the interference signals were precoded using a first type of precoding (e.g., linear precoding (LP)) or a second type of precoding (e.g., NLP). In another aspect, the described techniques provide for performing interference measurements on signals precoded using NLP based on categorizing interference resources as being precoded using LP or NLP. In this aspect, a receiving device may perform and report measurements differently for interference signals precoded using LP and interference signals precoded using NLP.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a first device may transmit a message indicating that the first device is operating on intermittently available energy harvested from outside the first device. The first device may receive a low-power wakeup signal. The first device may transmit, based at least in part on an energy harvesting state of the first device, an indication that the first device is capable of supporting continuous transmission and reception during a time frame having a configured duration. The first device may communicate during the time frame. Numerous other aspects are described.
