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: Methods, systems, and devices for wireless communications are described. A base station may identify time and frequency resources for a physical downlink shared channel (PDSCH) to be transmitted to a user equipment (UE) in a first transmission time interval (TTI). The base station may transmit configuration information for a control channel search space set in a second TTI. The second TTI may precede the first TTI. The configuration information may include an indication of an absence of a physical downlink control channel (PDCCH) transmission to send in the control channel search space set indicating the identified time and frequency resources for the PDSCH, and a set of time and frequency resources for the control channel search space set. The UE may receive the configuration information and identify the time and frequency resources allocated for the PDSCH in the second TTI, and receive the PDSCH transmission in the second TTI.

Abstract: Methods, systems, and devices for wireless communication are described. Wireless communications systems may support uplink random access channel (RACH) transmissions on multiple beams and over multiple component carriers (CCs). A wireless device may transmit a random access preamble to a base station in a first RACH transmission, which may indicate a set of CCs over which the base station may respond with a random access response (RAR) in a second RACH transmission. The second RACH transmission may then include an indication for which CCs the wireless device may use for a subsequent RACH transmission (e.g., a RACH message 3). The wireless device may also indicate a beam index and/or time-frequency resources associated with beams and/or CCs used for such cell acquisition transmissions. In other examples, the base station may indicate resources (e.g., via a handover command or RACH command) for wireless device scheduling request and/or beam-failure recovery request transmission.

Abstract: Methods, systems, and devices for wireless communications provide for transmission of a beam switch command to a user equipment (UE) via control channel signaling. The UE may establish a connection with a base station using a first transmission beam, receive configuration information configuring the UE to select between a first decoding hypothesis corresponding to downlink control information (DCI) including a bit field including a beam switch command and a second decoding hypothesis corresponding to the DCI not including the bit field, receive a downlink control channel transmission via the first transmission beam, decode the downlink control channel transmission in accordance with the configuration information to obtain decoded DCI, and communicate with the base station based at least in part on the decoded DCI.

Abstract: Various aspects described herein relate to techniques for signaling and using one or more virtual cell identifications (V-cell IDs) for single frequency network (SFN)-type of transmissions in wireless communications systems. A method, a computer-readable medium, and an apparatus are provided. In an aspect, the method may include performing, by a user equipment (UE), a cell search to obtain a cell ID, and decoding, by the UE, a message based on the cell ID, wherein the message includes a master information block (MIB). The method may further include identifying, by the UE, a virtual cell ID used for SFN-type transmissions based on information decoded from the message. The techniques described herein may apply to different communications technologies, including 5th Generation (5G) New Radio (NR) communications technology.

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: Aspects of the present disclosure relate to deriving spatial receive parameters for quasi-colocation at a user equipment (UE). An exemplary method generally includes receiving a plurality of beams from a base station in a plurality of coarse directions, determining, based on the plurality of beams, a first spatial colocation parameter, transmitting an indication of a coarse direction associated with a beam having a highest receive strength of the plurality of beams, receiving a plurality of second beams from the base station based on the indication, the plurality of second beams having a narrower beam width than the plurality of beams and covering a beam width of the beam associated with the indicated coarse direction, determining, based on the plurality of second beams, a second spatial colocation parameter, transmitting an indication of the second beam having a highest receive strength, and refining at least one of the first or second spatial colocation parameters.

Abstract: Aspects of the present disclosure relate to techniques that may enhance radio link failure (RLF) procedures. In some cases, a UE may perform radio link monitoring (RLM) based on reference signals (RS) transmitted using a first set of beams, perform beam failure recovery (BFR) monitoring based on transmissions using a second set of beams, and adjust one or more radio link failure (RLF) parameters based on both the RLM monitoring and the BFR monitoring.
