Abstract: A method, an apparatus, and a computer program product for wireless communication are provided. The apparatus receives a configuration indicating multicast broadcast single frequency network (MBSFN) subframes within a radio frame. The configuration indicates a number of symbols of an MBSFN subframe for receiving a wide area network (WAN) control signal and remaining symbols of the MBSFN subframe dedicated for peer-to-peer communication. The apparatus communicates with a peer via the symbols dedicated for peer-to-peer communication. Alternatively, the apparatus receives a configuration indicating a portion at a beginning and/or end of a guard period of a special time division duplex (TDD) subframe. The portion is reserved for an uplink timing advance and/or switching from transmission to reception and/or reception to transmission. The configuration also indicates a remaining portion of the guard period of the special TDD subframe for peer-to-peer communication. The apparatus communicates with a peer via the remaining portion.

Abstract: This disclosure provides systems, methods, and devices for wireless communication that support use of a supplemental uplink (SUL) carrier. In a first aspect, a user equipment (UE) is configured to receive, from a base station, a carrier set configuration indicating multiple uplink (UL) carriers. The multiple UL carriers include multiple SUL carriers and a non-SUL carrier. The UE is further configured to select one or more carriers of the multiple UL carriers, and transmit a channel on each carrier of the one or more carriers. Other aspects and features are also claimed and described.

Abstract: Certain aspects of the present disclosure propose techniques for transmitting uplink transmissions in special subframes for LTE TDD systems. Certain aspects provide a method that generally includes determining a region of uplink transmissions in uplink pilot timeslot (UpPTS), wherein the UpPTS comprises three or more symbols allocated for uplink transmissions, and transmitting in the UpPTS.
