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: Systems and methodologies are described that facilitate handing over mobile device communications in a wireless network from a source base station to a target base station without using a random access channel (RACH). In this regard, the mobile device can monitor multiple base stations determining timing information related thereto and access scheduling request channels for the base stations. When ready for handover, the mobile device can request data resources over the scheduling request channel using the appropriate timing information.

Abstract: A method of wireless communication for an enhanced new carrier type cell includes transmitting downlink common signals and channels at a low duty cycle while in a dormant state. The method also includes transmitting downlink common signals and channels at a high duty cycle while in an active state. Another method of wireless communication includes receiving a trigger; and switching a cell between an active state and a dormant state based on the received trigger.

Abstract: Techniques for low latency point to multipoint (PTM) communications in a system supporting communications using multiple different transmission time interval (TTI) durations are provided. The low latency PTM communications may be supported by one or more physical channels that support PTM communications at shortened TTI durations. In some examples, a base station may allocate, in a PTM traffic channel, a first set of resources for PTM transmissions with a first user equipment (UE) and a second UE, and may allocate a second set of resources (e.g., in a physical downlink shared channel (PDSCH)) for unicast transmissions to the first UE. The PTM transmissions may be transmitted using TTIs configured with durations shorter than TTIs used for transmitting unicast transmissions. Different sets of PTM resources may be allocated for different PTM transmissions having different TTI durations.

Abstract: Techniques are provided for transmitting reference signals and CSI reports within a wireless communications system using variable length downlink or uplink transmission time intervals (TTIs). CSI reference signals and CSI reports may be transmitted at times that accommodate the variable length TTIs. A UE may receive signaling that indicates when a CSI reference signal is to be transmitted, and when a CSI report is to be transmitted to a base station. CSI reporting may be performed periodically using a physical uplink control channel (PUCCH) in designated uplink symbols, may be aperiodic using a physical uplink shared channel (PUSCH), or a combination thereof. A UE may receive signaling indicating periodic CSI reporting, aperiodic CSI reporting, or both. Such signaling may be received, for example, via radio resource control (RRC) signaling or within a downlink or uplink grant.

Abstract: A device may determine that an unlicensed radio frequency (RF) spectrum band is available for a communication. The device may transmit a first transmission indicator that indicates that the device is transmitting information via the unlicensed RF spectrum band. The first transmission indicator may be associated with a first radio access technology. The device may transmit a second transmission indicator that indicates that the device is transmitting information via the unlicensed RF spectrum band. The second transmission indicator may be associated with a second radio access technology that is different from the first radio access technology.

Abstract: An opportunistic asynchronous operation for coordinated new radio (NR) shared spectrum (NR-SS) operations is discussed. In a wireless network having at least one contention-based shared channel in which communications are configured having one or more control intervals time division multiplexed with one or more data intervals for transmission opportunities, a base station receives data for communication at a time during a current data interval on a contention-based shared channel. The base station will review its received signals on the contention-based shared channel during the previous control interval located immediately prior to the current data interval. If none of the received signals indicate a contention-resolution of the contention-based shared channel, the base station may begin an attempted transmission by performing an abbreviated clear channel assessment (CCA). If the CCA is detected as clear, the data may be transmitted.

Abstract: A method of wireless communication includes receiving activation parameters at a low power node and detecting a proximity of an active user equipment (UE) based at least in part on the activation parameters. The activation parameters are triggered from a node different from the low power node, such as an eNodeB. The low power node initiates an activation sequence after detecting the active UE.

Abstract: Methods, systems, and devices are described contention-based channel access procedures that may enhance efficiency in communications using unlicensed spectrum. A time period may be identified during which base stations perform contention-based downlink channel access procedures for access to a channel in an unlicensed spectrum. The base stations may be coordinated such that different base stations may seek channel access during different time intervals during the time period. Contention-based uplink channel access procedures for UEs may then be modified to favor one or more UEs that are associated with a base station that has won channel access.
