Abstract: Various aspects described herein relate to managing ultra low latency (ULL) communications over a plurality of component carriers (CC). A configuration for aggregating a set of CCs can be received, wherein the set of CCs includes at least a primary cell and a secondary cell. Based on the received configuration, at least the primary cell can be communicated with for legacy communications, wherein the legacy communications are based on a first transmission time interval (TTI) having a first duration. Based on the received configuration, the primary cell and the secondary cell can be communicated with for ULL communications, wherein the ULL communications are based on a second TTI having a second duration that is less than the first duration.

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: A method, an apparatus, and a computer-readable medium for wireless communication are provided. In one configuration, the apparatus may be a UE. The UE receives PTM data from a base station. The UE attempts to decode the PTM data based on an identifier. The UE determines whether to transmit feedback information to the base station based on the attempt to decode the PTM data. In another configuration, the apparatus may be a base station. The base station transmits PTM data to a UE. The base station retransmits the PTM data to the UE based on feedback information associated with the transmitted PTM data.

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.

Abstract: Improvement in co-existence of the LTE device-to-device communication with another device-to-device communication method is desired. The apparatus selects a countdown number within a size of a contention window including a plurality of slots before a target subframe. The apparatus determines whether each slot of the plurality of slots is idle or utilized while waiting for the target subframe. The apparatus counts down the countdown number during each of the determined idle slots. The apparatus determines whether the countdown number has reached a threshold number before the target subframe. The apparatus performs, when the countdown number is determined to have reached the threshold number, one of: deferring from transmitting until the target subframe, or transmitting a CUBS until a next subframe or the target subframe.

Abstract: NB wireless communication involves numerous challenges. A limited frequency dimension may need to be shared by multiple users. At times, large data transmissions, including multiple TBs of data may be transmitted using NB communication, and it may be important that each TB be successfully received by the users. The apparatus may transmit data comprising a plurality of TBs in a narrow band communications system, including repeating a transmission of the plurality of TBs, using any of a number of repetition patterns. The apparatus may use error correction encoding across multiple TBs. The transmission may be a single cell transmission or a multi-cell transmission.
