Abstract: In wireless communication networks using carrier aggregation including a secondary component carrier in unlicensed spectrum, a user equipment (UE) may monitor a downlink radio link quality of secondary cells for an event indicating failure of a communication link in the unlicensed spectrum with a secondary cell. The UE detects one or more failure events based on the downlink radio link quality. When a designated set of failure events is detected, the UE declares a failure state on the secondary cell. In response to the failure state, the UE may adjust operations related to the secondary component carrier in the unlicensed spectrum in order to save power and resources.

Abstract: Techniques for managing co-existence on a shared communication medium are disclosed. An activation command or a deactivation command configuring an access terminal for activated operation or deactivated operation over a communication medium, respectively, may be exchanged in accordance with a Time Division Multiplexed (TDM) communication pattern defining active periods and inactive periods of communication over the communication medium. An acknowledgment message may be sent by, or received from, the access terminal in response to the activation command or the deactivation command. Communication may be activated or deactivated over the communication medium in accordance with the TDM communication pattern in response to the acknowledgment message indicating a positive acknowledgment of the activation command or the deactivation command, respectively, and not activated or deactivated over the communication medium in accordance with the TDM communication pattern in response to the acknowledgment message not indicating a positive acknowledgment of the activation or deactivation command.

Abstract: Methods, systems, and devices for wireless communications are described. A user equipment (UE) may receive, from a network entity, one or more control signals indicating information associated with a set of occasions for a transmission time interval (TTI) corresponding to a low power operation mode of the UE. For example, the set of occasions may include one or more of a wake up signal (WUS) monitoring occasion, a synchronization signal block (SSB) occasion, a channel state information (CSI) reporting occasion, and a discontinuous reception (DRX) on duration occasion. The UE may determine whether to skip the WUS monitoring occasion based on a respective duration and a respective start time for each occasion of the set of occasions associated with the information indicated by the one or more control signals.

Abstract: Apparatus, methods, and computer-readable media for providing improved power efficiency during DRX wake-up are disclosed. An example method of wireless communication at a UE includes receiving a WUS from a base station while performing a DRX cycle, the WUS indicating data for transmission to the UE. The example method also includes at least one receiving a downlink reference signal or transmitting an uplink reference signal based on the WUS and prior to reception of the data, the uplink reference signal transmitted or the downlink reference signal received during an on-duration of the DRX cycle and in response to receiving the WUS. The example method also includes sending a CSI report to the base station based on the WUS and prior to the receiving of the data. The example method also includes receiving the data following the respective receiving or transmitting of the downlink reference signal or uplink reference signal.

Abstract: Methods, systems, and devices for wireless communications are described that provide for service indication via downlink control information (DCI) in which different services have a same DCI size. Techniques provide also that a DCI format may be indicated by a masking operation on a cyclic redundancy check (CRC) of the DCI. The DCI may include an indicator field that may indicate the service of the associated operation. The indication may also be provided via different monitoring occasions of the DCI transmissions that are associated with different services. Different DCI search spaces also may be associated with different services and provide the service indication. Additionally or alternatively, different scrambling sequences used on all or a portion of control information or demodulation reference signal transmissions may be associated with different services.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may monitor a configured set of control channel elements (CCEs) for physical downlink control channel (PDCCH) decoding for a scheduled cell of a set of scheduled cells, wherein the configured set of CCEs is on a per scheduled cell basis or a per carrier indicator field value basis. The UE may decode downlink control information (DCI) in one or more CCEs of the monitored configured set of CCEs. Numerous other aspects are described.

Abstract: Various aspects described herein relate to techniques for synchronization channel design and signaling in wireless communications systems (e.g., a 5th Generation (5G) New Radio (NR) system). In an aspect, a method includes identifying a frequency band supported by a user equipment (UE), identifying one or more frequency locations based on the identified frequency band, and the one or more frequency locations are a subset of synchronization raster points used for synchronization signal transmission. The method further includes searching for at least one synchronization signal based on the one or more identified frequency locations.

Abstract: In an embodiment, a UE determines QCL information that indicates an association between a spatial parameter and a current transmission configuration, and conveys the determined QCL information to a BS. In another embodiment, a BS transmits a DCI that triggers transmission of a reference signal that includes QCL information that indicates an association between a spatial parameter and a current transmission configuration, whereby any DCI triggering any reference signal that includes any QCL information is configured to trigger a UE to send an express acknowledgment or an implied acknowledgment to that DCI.

Abstract: A wireless communication network includes a user equipment (UE) to receive a set of instructions, from a base station, to perform a simultaneous change of a set of current bandwidth parts (BWPs) to a set of new BWPs in a set of cells. The set of instructions schedules set of slots for the UE to receive and/or transmit a set of downlink and/or uplink signals via the set of new BWPs, respectively. The UE also determines a delay associated with performing the simultaneous change of the set of current BWPs to the set of new BWPs, respectively, and determines whether it is able to receive and/or transmit the set of downlink and/or uplink signals via the set of new BWPs in the set of slots satisfying the delay, respectively. A base station is also included to communicate with the UE to effectuate the aforementioned operation.
