Abstract: A method, an apparatus, and a computer program product for wireless communication are provided. The apparatus determines an interference type between a time division duplex (TDD) configuration subframe of a serving cell and a corresponding TDD configuration subframe of a neighboring cell, and sets a transmit power for an apparatus in the serving cell based on the interference type. The apparatus in the serving cell may be a user equipment (UE), in which case the apparatus applies a set of uplink (UL) open loop power control parameters for the UE. The apparatus in the serving cell may be a base station (eNB), in which case a DL transmit power is set for the eNB. Depending on the interference type, the DL transmit power may be a fixed, full power DL transmission or an adjusted DL transmission.

Abstract: An apparatus may use inactive uplink portions of a downlink CC to transmit SRS to an eNB. At times there may be a collision between the SRS transmission and uplink transmissions or downlink transmissions on another CC. The apparatus receives a carrier aggregation configuration for a first downlink CC and a second CC, determines to transmit an uplink transmission on the second CC or to receive a downlink transmission on the second CC, determines that the SRS would at least partially collide with the uplink transmission or the downlink transmission, and determines to adjust at least one of the uplink transmission, the SRS transmission, or reception of the downlink transmission based on the determination of the collision and an interruption time to transmit the SRS in the uplink portion of the first CC.

Abstract: Coverage enhancement of an eMTC system may be limited if an MTC device switches from transmission mode to reception mode using subframes that may be utilized for transmissions or receptions. The present disclosure provides, among others, a mechanism by which a device may determine a set of valid subframes for use in communicating via a backhaul link, an access link, and/or a direct link. In addition, the present disclosure provides a mechanism by which a device may switch between different communication link operations using subframes that are unavailable for transmitting and/or receiving data. The apparatus may receive repetition configuration information from a base station in communication with the relay node. In addition, the apparatus may determine a backhaul repetition configuration for a backhaul link and an access link repetition configuration for an access link at the relay node based at least on the repetition configuration received from the base station.

The described aspects include receiving a transmission having a first subframe slot and a second subframe slot, at least one of the first subframe slot and the second subframe slot have a single-slot transmission time interval (TTI). The described aspects further include detecting a first demodulation reference signal (DM-RS) in the first subframe slot and a second DM-RS in the second subframe slot. The described aspects further include determining whether to demodulate the at least one downlink channel in the first subframe slot using the first DM-RS in the first subframe slot or to demodulate both the first DM-RS in the first subframe slot and the second DM-RS in the second subframe slot based on whether at least one condition exists.

Abstract: Certain aspects of the present disclosure relate to methods and apparatus for pilot design for Narrow-Band Internet of Things (NB-IoT). In certain aspects, the method generally includes determining at least one binary code sequence to use as a demodulation reference signal (DMRS) for a channel transmitted across one or more subframes using one or more tones within a resource block (RB) allocated to the UE for narrowband communication, and transmitting the channel including the DMRS using the one or more tones and the determined binary code sequence. In certain aspects, the binary code sequence may be determined based on a binary random sequence, such as pseudo noise (PN) or Gold sequence.

Abstract: Various aspects described herein relate to scheduling resources in wireless communications. In one aspect, communications can be established with a plurality of user equipment (UE). A set of the plurality of UEs as having an interference impact on one another that is less than a threshold can be determined. A first UE of the set of the plurality of UEs can be scheduled for downlink communications in a first transmission time interval (TTI), and a second UE of the set of the plurality of UEs can be scheduled for uplink communications in a second TTI that is adjacent in time to the first TTI. In another aspect, uplink communications for the first UE can be scheduled in a portion of the guard period TTI based at least in part on determining a timing advance of the first UE is less than a threshold.
