Abstract: Aspects described herein relate to communicating in a wireless network. Downlink control information having a dynamic resource allocation indicator can be received from a serving access point. It can be determined whether the dynamic resource allocation indicator indicates at least one symbol in a subframe is for uplink data communications or reference signal transmission. Uplink data communications can be transmitted using the at least one symbol based at least in part on the determination that the dynamic resource allocation indicator indicates the at least one symbol in the subframe is for the uplink data communication, though a broadcasted reference signal configuration may indicate otherwise. Numerous other aspects are provided.

Abstract: Aspects of the present disclosure provide techniques and apparatus for determining presence and/or bandwidth of reference signals (RS) in systems that utilize narrowband regions of wider system bandwidth for wireless communications, such as enhanced machine type communication(s) (eMTC) systems and/or narrowband Internet-of-Things (NB-IoT) systems. Aspects provide a method for wireless communications by a user equipment (UE) operating in a narrowband region of a wider system bandwidth. The method generally includes determining at least one of: a presence of one or more RS in a subframe or a bandwidth of the one or more RS, wherein the bandwidth of the one or more RS is greater than or equal to a bandwidth of the narrowband region; and monitoring for the one or more RS in the subframe based on the determination.

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.

Abstract: Aspects of the present disclosure provide procedures for handling interruption due to carrier switching for sounding reference signal transmission and for a carrier switching capability indication. A method by a user equipment (UE) is provided, generally including interrupting communication on a first component carrier (CC) to switch between the first CC and a second CC to transmit an uplink reference signal on the second CC and adjusting one or more parameters of an uplink transmission on the first component carrier to account for the interrupting communication on the second CC. In aspects, another method is provided in which, a UE receives a query from a base station for switching capability information of the UE for one or more carrier aggregation (CA) configurations and, in response to the query, provides an indication to the BS of the switching capability information of the UE for the one or more CA configurations.

Abstract: In order to address the needs of narrow band communication, eNB-based processing and/or UE-based processing is provided to achieve robust detection of cell ID and SFN timing location using NB-SSS. A base station constructs a NB-SSS signal using a root index of a Zadoff-Chu (ZC) sequence, a scrambling code, a cyclic shift or phase ramping sequence, and an interleaving sequence, wherein a combination of the ZC root index, the scrambling code index, the cyclic shift or phase ramping sequence index, and the interleaving sequence index signals information for a cell identifier (e.g., PCID) and frame timing. The ZC sequence used may be a long ZC sequence constructed to span a total number of tones allocated to an SSS sequence or may be a concatenation of multiple ZC sequences, wherein the concatenated ZC sequences span a total number of tones allocated to an SSS sequence.

Abstract: The present disclosure proposes indicating to the UE a set of CSI reference subframes that may be used in performing a CSI measurement. The set of CSI reference subframes may be measured over multiple frequencies when frequency hopping occurs. In an aspect of the disclosure, a method, a computer-readable medium, and an apparatus are provided. The apparatus may receive information associated with a number of CSI reference subframes to use in performing CSI measurements in a narrowband communication. In addition, the apparatus may monitor subframes on at least two frequency channels including a PDCCH. Further, the apparatus may perform a CSI measurement across the at least two frequency channels based on the information associated with the number of CSI reference subframes.
