Abstract: A base station may make more efficient use of resources by transmitting data in a control region of a slot in addition to a data region. In order to avoid performance loss, the base station may adjust the data transmission in the control region in comparison to a data transmission in a data region and may signal an indication to a UE to assist the UE in receiving the data transmission in the control region. An apparatus for wireless communication at the UE receives the indication from the base station regarding the data transmission in the control region and uses the indication to perform rate matching or demodulation of the data transmission in the control region. The indication may indicate any of a different MCS/rank/TPR, a reduced MCS/rank/TPR, an MCS/rank/TPR delta, a control span for a group of UEs, and a starting symbol for the data transmission. The indication may also indicate that there is no data transmitted on resources in the control region.

Abstract: In order to provide a more robust RLM procedure for 5G/NR, a base station may provide a dynamic relationship between a PDCCH and another reference signal (e.g., SS/CSI-RS) to a UE. For example, an apparatus may receive an adjustment parameter regarding a PDCCH from a base station. The adjustment parameter may comprise a relationship between the PDCCH and the at least one of the SS or the CSI-RS for deriving a radio link quality of a hypothetical PDCCH. The apparatus may receive an SS/CSI-RS that is QCL with the PDCCH and perform a radio link measurement based on the received at least one of the SS or the CSI-RS using the adjustment parameter regarding the PDCCH. Among other relationships/offsets, the adjustment parameter may indicate a TPR difference, a beamforming gain difference, a beam width difference, a beam orientation difference.

Abstract: Certain aspects of the present disclosure provide techniques for selecting an uplink (UL) transmit beam by a user equipment (UE). A UE may receive, from a base station (BS), one or more beamformed downlink signals using one or more receive beams. The UE may select an uplink transmit beam based, at least in part, on the one or more beamformed downlink signals. The UE may transmit an uplink signal using the selected uplink transmit beam.

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: Aspects of the present disclosure implement techniques to allow a base station to transmit a “short-page” message (e.g., paging indicators) to one or more UEs. The short-page message may be decoded by all UEs in the paging cycle and identifies a subset of UEs from the full set of UEs that are paged by the base station. Upon decoding the short page transmitted by the base station, the UE may respond with a “short-page response” to the base station on a transmit beam that offers best signal quality (e.g., low signal-to-noise ratio, transmit power, etc.). Thus, in some examples, the UE, in response to receiving a short paging message, may provide feedback to the base station such that the base station may select a transmit beam for transmission for a subsequent message (and other communications).

Abstract: Wireless communications systems and methods related to synchronization signal (SS) transmission coordination among base stations (BSs) and restricted SS measurements at user equipments (UEs) are provided. A first BS transmits a first SS burst in a first SS transmission period of a plurality of SS transmission periods. The first SS transmission period is designated to the first BS. A second SS transmission period of the plurality of SS transmission periods is designated to a second BS. The first SS transmission period and the second SS transmission period are different. The first BS receives, from a UE, a first signal in synchronization with the first SS burst. The first signal includes a SS measurement of the first SS burst.

Abstract: Networks that support 5G communication may support different numerologies across and even within a symbol, slot, or subframe. Sequences, such as reference signals or data scrambled with a scrambling code, may be transmitted on resources with such mixed numerologies. In an aspect of the disclosure, a method, a computer-readable medium, and an apparatus are provided. The apparatus may be a user equipment. The UE may be configured to receive an indication of assigned resources for communicating with a base station. The UE may also be configured to determine a numerology associated with the assigned resources, and to determine one or more indices based on the numerology. The UE may also generate a sequence based on the one or more indices and communicate with the base station based on the sequence.

Abstract: Certain aspects of the present disclosure provide techniques for using beam sets for mobility management. A BS serving the UE may transmit, to the UE, information regarding one or more beam sets, wherein each of the beam sets comprise one or more reference beams used to transmit a reference signal. The BS may transmit, to the UE, one or more mobility parameters, wherein the mobility parameters are associated with the reference beams and one or more mobility event triggers. The BS may receive, from the UE, an indication of a detected mobility event, the mobility event is detected based, at least in part, on the mobility parameters. The BS may take one or more actions based, at least in part, on the indication. A UE may perform corresponding steps as described herein.
