Abstract: Methods, systems, and devices for wireless communication are described. A method may include receiving a control transmission from a base station, identifying a control channel search space organized according to a nested structure, the control channel search space including a plurality of control channel candidates associated with one or more control channel elements (CCEs) and an aggregation level, and searching the received control transmission to identify a control channel for the UE using the plurality of control channel candidates. Another method may include determining whether to reorder resource element group (REG) indices for a received control channel transmission based, at least in part, on a transmission mode associated with the control channel transmission. Another method may include decoding a received control channel transmission, where the downlink control information (DCI) formats may be constrained to an integer multiple of a predetermined base number of bits N.

Abstract: Wireless communication devices are adapted to facilitate a random access procedure. According to one example, scheduled entity can transmit a first transmission that is received by a scheduling entity. The first transmission may include a physical random access channel (PRACH) preamble sequence and a first message including information for determining a device-specific network identifier for the scheduled entity. The scheduling entity may transmit a second transmission that is received by the scheduled entity. The second transmission may include information on a physical downlink control channel (PDCCH) addressed to the device-specific network identifier for the scheduled entity, and a second message on a physical downlink shared channel (PDSCH). Other aspects, embodiments, and features are also included.

Abstract: Methods, systems, and devices for wireless communications are described. In one example, a method includes receiving signaling from a base station to activate a semi-persistent scheduling (SPS) configuration for transmission between the base station and the UE, and receiving a hybrid automatic repeat request (HARM) timing for downlink transmissions based at least in part on the SPS configuration being activated. In another example, the method includes establishing a connection with a base station using a component carrier (CC), the CC having a plurality of bandwidth parts (BWPs), receiving signaling that indicates an SPS configuration or other types of pre-configured resources associated with at least a first BWP of the plurality of BWPs and transmitting or receiving using at least the first BWP according to the SPS configuration or other types of pre-configured resources associated with at least the first BWP.

Abstract: A UE may enter a dormant state, e.g., for power savings. The systems, methods, and apparatus described herein may provide ways for the UE to transition between an active state and a dormant state, as well as UE behavior in a dormant state. The apparatus may be a UE configured to receive downlink control information (DCI) comprising an indication of a bandwidth part (BWP) switch for a secondary cell to a dormant BWP and transition the secondary cell from an active state to a dormant state based on the indication of the BWP switch of the secondary cell to a dormant BWP.

Abstract: Methods, systems, and devices for wireless communications are described. A base station may implement cross-carrier scheduling. A user equipment (UE) may identify a minimum scheduling delay and may receive a downlink grant on a first CC. The UE may further identify the slot in which a downlink data transmission corresponding to the downlink grant will be received, and may identify the slot such that the minimum scheduling delay is satisfied. The UE may the receive the downlink data transmission, as indicated in the downlink grant, in the identified slot. In some examples, the UE and the base station may alternate between a long minimum scheduling delay and a short minimum scheduling delay. In some examples, the UE and the base station may alternate between a cross-carrier mode, and a self-scheduling mode.

Abstract: Certain aspects of the present disclosure relate to communication systems, and more particularly, to system information acquisition over bandwidth parts (BWPs) in communications system operating according to new radio (NR) technologies. In an exemplary method, a user equipment (UE) receives system information (SI) via a transmission in a downlink (DL) bandwidth part (BWP) of a system bandwidth and transmits, to a serving base station (BS) and in response to receiving the SI, an indication that the UE has completed SI acquisition.

Abstract: Certain aspects of the present disclosure generally relate to methods and apparatus for downlink control information (DCI) communication and processing. One example method generally includes determining a limit, between a transmission time of a control channel carrying a DCI of a plurality of DCI and a time of an event enabled by the DCI, of a quantity of the plurality of DCI in a frame, generating a frame comprising the plurality of DCI in accordance with the determined limit, and transmitting the frame to a user-equipment (UE).

Abstract: Disclosed are techniques for enabling a user equipment (UE) operating in carrier aggregation mode to use different connected mode discontinuous reception (CDRX) configurations for different sets of component carriers associated with different sets of numerologies. For example, in Frequency 1 (FR1) plus Frequency 2 (FR2) carrier aggregation (i.e., one or more FR1 component carriers and one or more FR2 component carriers), a different CDRX can be configured for FR1 than for FR2. In inter-band carrier aggregation (i.e., one or more component carriers in one frequency band and one or more component carriers in another frequency band), CDRX can be configured per band. For mixed numerologies carrier aggregation (i.e., one or more component carriers with a first numerology and one or more component carriers with a different numerology), CDRX can be configured per cell group, where each cell group contains a single numerology or mixed numerologies.
