Abstract: Aspects of the present disclosure generally relate to a conditional utilization of reference signals for managing communications of one or more user equipment (UE) in a wireless communications system. 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: Various aspects described herein relate to allocating resources in wireless communications. A subset of resource block (RB) groups configured for a legacy wireless communication technology having a first transmission time interval (TTI) can be determined, where the first TTI is based on one subframe in duration, and where each RB group in the subset of RB groups includes one or more RBs. A resource allocation for a low latency communication technology having a second TTI, the second TTI being less than one subframe in duration, can be determined where the resource allocation including one or more low latency RBs in the subset of RB groups. Data can be communicated over resources in the one or more low latency RBs, the low latency RBs being based on the second TTI, and the resources being associated with the resource allocation.

Abstract: Aspects of the present disclosure provide techniques for physical broadcast channel (PBCH) and master information block (MIB) design. An example method is provided for operations which may be performed by a user equipment (UE). The example method generally comprises receiving, a first number of symbols within a first subframe on a physical channel, performing a first blind decode on the first number of symbols to obtain a first set of bits, performing one or more cyclic shifts on the first set of bits, calculating a redundancy check value for the first set of bits, and decoding an information block based on the whether the redundancy check value passes. Aspects of the present disclosure provide techniques for transmission configurations. An example method is provided for operations which may be performed by a base station (BS). The example method generally comprises selecting a transmission configuration, from a set of predetermined transmission configurations, based on a deployment configuration, generating a signal having an indication of the deployment configuration, and transmitting the signal.

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.

Abstract: Half-duplex (HD) operations enable low cost implementations of LTE terminals. Traditionally, HD operations may be linked to a particular frequency band which may not allow a mix of full-duplex (FD) and HD terminals in the same frequency band. Therefore, certain aspects of the present disclosure provide techniques for enabling coexistence, in a given frequency band, of HD and FD terminals, by introducing frequency bands designated for HD operation and overlapping existing frequency bands designated for FD operation.
