Abstract: Various aspects of the disclosure relate to use of a default communication configuration for cross carrier wireless communication. For example, a wireless communication device such as a user equipment (UE) may use a default communication configuration that includes quasi-colocation information (e.g., a default CORESET configuration) for communication on a secondary component carrier (SCC). The default communication configuration may be used, for example, in scenarios where a CORESET is not defined for the SCC and other configuration information is not available. For example, other configuration information might not be available due to a short time gap between a grant sent on a primary component carrier (PCC) and the communication on the SCC scheduled by the grant.

Abstract: Certain aspects of the present disclosure provide techniques for sounding reference signal (SRS) resource configuration enhancements. A method generally receiving pre-configuration information for one or more reference signal transmissions, performing, at a first time during an ON duration of a discontinuous reception (DRX) cycle, measurements on one or more reference signals based, at least in part, on the pre-configuration information, determining if, at a second time during the ON duration after the first time, a trigger frame associated with the one or more reference signal transmissions has been received, and transmitting a measurement report corresponding to the measurements if a trigger frame has been received.

Abstract: Aspects described herein relate to configuring a media access control (MAC)-control element (CE) to update a sounding reference signal (SRS) beam within a wireless communication system. Other aspects described herein relate to configuring default beam information for determining a beam for data channel communications within the wireless communication system. A user equipment (UE) or other device can determine to use the default beam information for configuring the beam for a data channel communication and for performing power control using, e.g., physical uplink shared channel (PUSCH) parameters. In addition, in some examples, the device can transmit the data channel communication using a beam configured based on the default beam information.

Abstract: A method of wireless communication includes receiving, at a user equipment (UE), a grant from a base station on a control channel, the grant including content indicating a mini-slot assigned to the UE. The method may include interpreting the grant based on a current configuration of a data channel to determine the mini-slot. The method may include communicating with the base station during the mini-slot indicated by the grant.

Abstract: Certain aspects of the present disclosure relate to methods and apparatus for radio link monitoring reference signal (RLM-RS) determination using communications systems operating according to new radio (NR) technologies. For example, a method for wireless communications from a UE generally includes determining resources to monitor for radio link monitoring (RLM) prior to being configured with resources to monitor for RLM after establishing a radio resource control (RRC) connection with a network, and performing RLM based on the determined resources.

Abstract: Methods, systems, and devices for wireless communication are described. A wireless device may identify a characteristic of a first beam associated with a first antenna array, determine a second beam associated with a second antenna array as a quasi-co-located beam with respect to the first beam based on the characteristic, and communicate on the first and second beams based on the determining. A base station may identify a user equipment (UE) searching for a connection with a secondary cell on a second frequency band, wherein the UE is served by the base station on a first frequency band and transmit an indicator to the UE to inform the UE regarding selection of a particular beam for measuring a reference signal from the secondary cell.

Abstract: Aspects of the present disclosure provide various apparatuses and methods for extending a reference signal to facilitate carrier aggregation (CA). In some examples, a network includes a primary cell and one or more secondary cells that use a millimeter wave (mmW) carrier. When a UE is beyond the range of a reference signal from the secondary cell, the primary cell may trigger the secondary cell to increase the range of its reference signal using a higher gain beam and/or reference signal repetition.

Abstract: An apparatus may receive a master information block and a synchronization signal (SS) block on a PBCH. The MIB may indicate an allocation associated with a CORESET. The apparatus may receive remaining minimum system information (RMSI) configuration information carried in the CORESET based on the allocation associated with the CORESET. The apparatus may determine a position associated with a downlink data channel based on a first value indicated by one of the MIB or the SS block in the PBCH and based on a second value indicated by the RMSI configuration information. The apparatus may receive data carried on the downlink data channel based on the position associated with the downlink data channel.
