Abstract: Control channel decoding can consume a significant amount of power with respect to the device's total power battery lifetime, as well as being a factor in the complexity of device. Aspects of a method, apparatus, and computer-readable medium are presented herein that provide a solution to the problem of control channel decoding complexity and power requirements by improving the manner in which control channels are decoded. An apparatus configures an initial CORESET having a reduced bandwidth corresponding to a bandwidth capability of a first UE type. The reduced bandwidth having a narrower frequency range than a bandwidth capability of a second UE type. The apparatus may configure a first CORESET for a first UE having a first bandwidth capability and a second CORESET for a second UE having a second bandwidth capability. The apparatus transmits control channel(s) in the configured CORESET(s).

Abstract: Techniques are described for wireless communication. One method includes identifying a transmission time interval (TTI)-level control region, where the cascaded control region includes a TTI-level common control region and a TTI-level UE-specific control region, and where the TTI-level common control region has a pointer to a location of the TTI-level UE-specific control region; and demodulating at least one of the TTI-level common control region and the TTI-level UE-specific control region. Some techniques enable control information in a first region to point to a second region that includes additional control information. Some techniques enable two-stages of control. Semi-persistent scheduling/prescheduling control may be configured to cause an entity to refrain from demodulating one of the stages of control.

Abstract: Methods, systems, and devices for configuring physical downlink control channel candidates are described. The method may include monitoring, by a UE, an initial set of physical downlink control channel candidates in a first slot, receiving, by the UE, an indication of an adjusted set of physical downlink control channel candidates to monitor in a second slot based on decoding a physical downlink control channel candidate in the initial set, and monitoring, by the UE in the second slot, the adjusted set of physical downlink control channel candidates. The method may also include adaptively (e.g., autonomously) determining, by the UE, the adjusted set of physical downlink control channel candidates, and corresponding determinations by the base station.

Abstract: A user equipment (UE) identifies a conflict between a system resource and a wake-up signal (WUS) resource associated with the UE while the UE is operating based on discontinuous reception (DRX). The UE modifies DRX operation in response to identifying the conflict between the system resource and the WUS resource. A base station identifies a conflict between a system resource and a WUS resource for a UE operating based on DRX. The base station modifies a transmission to the UE in response to identifying the conflict between the system resource and the WUS resource.

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: Methods, systems, and devices for wireless communications are described. A communication device, otherwise known as a user equipment (UE) may transmit capability information including an indication of a discontinuous monitoring delay period. The UE may receive a message including an indication to adjust monitoring of a physical downlink control channel (PDCCH), and monitor for the PDCCH during the discontinuous monitoring delay period. The UE may adjust monitoring for the PDCCH following the discontinuous monitoring delay period during a temporal period based on the received indication to adjust monitoring of the PDCCH. In some examples, at least one of physical downlink shared channel (PDSCH) reception, downlink reference signal monitoring, uplink reference signal transmissions, and channel reporting is enabled during the temporal period while monitoring of the PDCCH is adjusted.

Abstract: Wireless communications systems may support user equipment (UE)-specific hybrid automatic repeat request (HARQ) timeline offsets such that transmission time intervals (TTIs) reserved for uplink HARQ transmissions are reserved on a per UE basis (e.g., TTIs are not reserved or designated on a network level or aligned across all or many UEs within the system). That is, UEs within a wireless communications system may employ a UE-specific offset for their respective HARQ timelines. UE-specific HARQ timeline offsets may be derived, by the UEs, explicitly or implicitly. Further, the network (e.g., a base station) may configure UE-specific HARQ timeline offsets to be distributed in time to avoid uplink HARQ transmission collisions between UEs, to eliminate the loss of TTIs for a second carrier operation (e.g., such as NR uplink) on a network wide basis, etc. The base station may then communicate with the UEs according to their corresponding UE-specific offset HARQ timelines.

Abstract: In an aspect, a UE may determine a set of parameters associated with each of a plurality of different operation modes supported by the UE and transmit UE capability information including the set of parameters to a base station, where at least one operation mode comprises a power efficient mode. The UE may receive configuration information based on the UE capability information including an indication of an operation mode of the plurality of different operation modes. A base station may receive UE capability information including a set of parameters associated with each of a plurality of different operation modes supported by a UE and determine an operation mode of the plurality of different operation modes for the UE based on the UE capability information. The base station may transmit configuration information including an indication of the operation mode of the plurality of different operation modes.

Abstract: Bandwidth part (BWP) configurations supporting various communication approaches (e.g., full duplex and/or half duplex operations) are described. Full duplex (FD) frequency-based BWP configurations may, for example, be configured as a subset of defined BWP resources for supporting full duplex operation by base stations and/or user equipments (UEs). Usable bandwidth of a FD frequency-based BWP configuration may be selected from half duplex frequency-based BWPs in legacy BWPs. Bandwidths of usable BWPs for a FD frequency-based BWP configuration may be selected so as to be non-overlapping in frequency. Transition between configurations and modes (e.g., between full duplex frequency-based BWP configurations, between half duplex and full duplex modes, etc.) may be managed to avoid periods in which a communication device cannot perform any uplink or downlink transmissions due to switching between defined BWP configurations, or otherwise reduces BWP switching time. Other aspects and features are also claimed and described.

Abstract: Methods, systems, and devices for wireless communications are described. In some systems, a user equipment (UE) and a base station may support beamforming communication techniques and may communicate using one or more beams. The UE may support a bandwidth part (BWP) hopping pattern and may perform a beam failure detection (BFD) procedure across the supported BWPs. While performing the BFD procedure, the UE may declare beam failure and may determine whether to switch to an anchor BWP to initiate a beam failure recover (BFR) procedure or to remain on an active BWP to initiate the BFR procedure. In some implementations, the UE may determine whether to switch to the anchor BWP or to remain on the active BWP to initiate the BFR procedure based on an indication from the base station.
