Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment may receive carrier information identifying at least one of: an initial absolute frequency for a carrier, a tone boundary offset value for the carrier, a number of resource blocks included in the carrier, or a frequency offset from a reference frequency; and determine a resource allocation of the carrier based at least in part on the carrier information and a subcarrier spacing of the user equipment. Numerous other aspects are provided.

Abstract: Techniques for uplink transmission management in a wireless communications system are described herein. An example method may include receiving an explicit uplink grant that indicates one or more implicit uplink grants. In an aspect, the example method may include performing a first clear channel assessment (CCA) in response to the explicit uplink grant in a first time slot. In another aspect, the example method may include, if the first CCA fails, sequentially performing one or more additional CCAs respectively in one or more time slots subsequent to the first time slot in response to the one or more implicit uplink grants, and transmitting the PDU over the unlicensed or shared spectrum and in a time slot subsequent to the time slot in which one of the one or more additional CCAs succeeds.

Abstract: Aspects of the present disclosure relate to methods and apparatus for optimizing real time services (e.g., such as a voice over Long Term Evolution (LTE) (VoLTE)) for devices with limited communications resources, such as machine type communication (MTC) devices and enhanced MTC (eMTC) devices. In one aspect, a UE determines a first configuration of subframes within at least one radio frame available for the UE and other UEs to use for bundled communications with a BS. The UE receives an indication of one or more subframes within the at least one radio frame that are unavailable for bundled uplink transmissions, and determines a second configuration of subframes to use for bundled communications based on the indication. The UE overrides the first configuration of subframes with the second configuration of subframes, and communicates with the BS using the second configuration of subframes. Numerous other aspects are provided.

Abstract: Aspects of the disclosure relate to wireless communication systems configured to provide techniques for strategically placing a sounding reference signal (SRS) within a slot to improve the decoding timeline. Aspects of the disclosure further relate to wireless communication systems configured to optimize the physical downlink control channel (PDCCH) search space within a slot to improve the decoding timeline. Features may also include placing the SRS near the end of the slot, such as after the uplink user data traffic and the corresponding uplink demodulation reference signal (DMRS). In addition, features may also include identifying the PDCCH search space within the slot based on at least a slot index of the slot. Other aspects, embodiments, and features are also claimed and described.

Abstract: Dynamic channel state information (CSI) reference signal (CSI-RS) activation/deactivation via layer 1 signaling is discussed. An eNB may configure multiple dynamic CSI-RS resource configurations for a given user equipment (UE). Multiple dynamic CSI-RS configurations may be associated with CSI processes, and also one or more dynamic CSI-RS resources may be associated with multiple CSI processes. Each dynamic CSI-RS resource configuration may include the number of ports, RE locations, and power ratio, as well as the subframe configuration, which may include periodicity and subframe offset. The eNB may dynamically trigger or release the different dynamic CSI-RS resources through layer 1 signaling. Additional aspects provide for ways to determine dynamic CSI-RS transmission instances, to enhance rate matching to support dynamic CSI-RS transmissions, and to report CSI for dynamic CSI-RS resources.

Abstract: Aspects of the disclosure relate to wireless communications utilizing discontinuous reception (DRX). Disclosed methods and apparatus include providing a grant indicator in a transmission from a base station to a user equipment (UE), where indicator notifies the UE of a grant of data during a subsequent discontinuous reception (DRX) cycle in the at least one UE. Additionally, a tracking reference signal (TRS), which may be aperiodic (A-TRS), is transmitted prior to an on-duration time of the DRX cycle, where the TRS is usable by the UE for updating a tracking loop and also can be referenced by the indicator. In this manner, the combination of the grant indicator and the TRS affords a UE sufficient time for updating a UE tracking loop before the DRX cycle. Other aspects, embodiments, and features are also claimed and described.

Abstract: Certain aspects of the present disclosure relate to methods and apparatus for generating and communicating reference signals. Certain aspects provide a method for communicating reference signals. The method includes selecting a demodulation reference sequence (DMRS) of a plurality of DMRSs for transmission in a synchronization signal block (SSB) based on a half-frame in which the SSB is transmitted. The method further includes transmitting the selected DMRS in the SSB.

Abstract: The present disclosure provides user equipment power consumption and secondary cell (SCell) activation latency reductions in wireless communication systems. For example, a UE may determine that a secondary cell activation condition has been satisfied. The UE may further transition to a secondary cell activated state based on determining that the secondary cell activation condition has been satisfied, the secondary cell activate state corresponding to a dormant SCell state. The UE may operate at least in the dormant SCell state.

Abstract: Certain aspects of the present disclosure relate to methods and apparatus relating to a long uplink burst channel design. In certain aspects, the method includes determining, based on a hopping pattern, a first set of frequency resources available for transmitting uplink control information (UCI) within a first portion of a transmission time interval (TTI) and a second set of frequency resources available for transmitting UCI within a second portion of the TTI. The method also includes transmitting the UCI using the determined first set of frequency resources and the second set of frequency resources.
