Abstract:
Embodiments herein provide techniques and requirements for radio resource management (RRM) measurements. For example, embodiments include techniques and requirements associated with: channel state information (CSI)-reference signal (RS) based inter-frequency RRM measurements when the CSI-RS bandwidth and the active downlink (DL) bandwidth part (BWP) are partially overlapped; adaptive RRM CSI-RS configuration and DL gap allocation by user equipment (UE) capability indication; and/or neighboring cell RRM CSI-RS measurement requirements when serving cell RRM CSI-RS is not configured. Other embodiments may be described and claimed.
Abstract:
Systems and methods provide solutions for delay and interruption requirements for vehicle-to-everything (V2X) sidelink carrier aggregation (CA). For example, when any number of component carriers is added for V2X CA, a user equipment (UE) capable of V2X sidelink communication is allowed an interruption of up to two subframes to the cellular network. The interruption may be for both uplink and downlink of a serving cell or primary cell.
Abstract:
An apparatus of user equipment (UE) includes processing circuitry coupled to a memory, where to configure the UE for New Radio (NR) vehicle-to-everything (V2X) sidelink communication. The processing circuitry is to decode radio resource control (RRC) signaling from an authorized V2X network entity. The RRC signaling including configuration information to activate a sidelink transmit (TX) bandwidth part (BWP) of a plurality of sidelink TX BWPs within a sidelink carrier. Data is encoded for transmission to a second UE using a first sidelink signal. The processing circuitry is to cause transmission of the encoded data via the first sidelink signal. A bandwidth of the first sidelink signal during the transmission is within the activated sidelink TX BWP.

Abstract:
Increasing a number of orthogonal time-domain transmission opportunities in a Proximity Services (ProSe) traffic generation period can reduce over-air congestion and collision in long term evolution (LTE) communications. Resource configurations can be adjusted, including providing a new physical layer numerology, reducing transmission time (TTI) interval duration, providing a smaller sidelink control information period, configuring logical sidelink control periods and/or multiplexing of control and data transmissions.
Abstract:
Techniques for adjacent channel interference mitigation are described. In one embodiment, for example, a user equipment (UE) may comprise logic, at least a portion of which is in hardware, the logic to associate the UE with a pico evolved node B (eNB) in a time-division duplex (TDD) picocell, identify an incongruent uplink (UL) sub-frame for the picocell, and select an enhanced UL transmit power for the incongruent UL sub-frame. Other embodiments are described and claimed.

Abstract:
Some demonstrative embodiments include devices, systems and/or methods of Time-Division Duplexing (TDD) Uplink-Downlink (UL-DL) configuration management. For example, a node may communicate a message including a cell identifier identifying a first cell controlled by the node, and a TDD configuration update to update at least one other node, which controls at least one second cell, with a TDD UL-DL configuration allocated by the node for communication within the first cell.
Abstract:
An apparatus and system of establishing a Transmission Configuration Indication (TCI) state switch delay are described. The TCI state switch delay for a reference signal (RS) on a component carrier (CC) in intra-band carrier aggregation (CA) is dependent on whether a TCI state indicated in the DCI is known based on a type of Quasi Co-Location (QCL) and whether a common TCI state ID is known on the CC. The delay is known for a delay of QCL-typeD RS on the CC or any other QCL-typeD RS in the CC set that contains the CC. The delay may be based on that of a single CC delay, with the slot where the new TCI state applies determined based on a carrier with a smallest subcarrier spacing (SCS) in the CC or the CC set.
Abstract:
An apparatus and system for a unified transmission configuration indicator (TCI) state switch requirement are described. Both radio resource management and TCI state switch delay requirements are described. The UL TCI state switch delay requirement may depend on whether a downlink (DL) reference signal (RS) associated with the UL TCI state satisfies known conditions, as well as whether a joint or separate TCI mode is being used. In the separate TCI mode. the delay requirement may include timing between a DL data transmission and acknowledgement, and also include a time for receive beam refinement in frequency range2. In the joint TCI mode. the UL and DL TCI state switch delay requirement—due may be the same or may be the same as the separate TCI mode.
