Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a wireless communication device may determine a scrambling sequence for a control channel, wherein the scrambling sequence is determined using a same identifier irrespective of whether the control channel is associated with a cell radio network temporary identifier (C-RNTI) or another type of RNTI, and wherein the scrambling sequence is determined based at least in part on an identifier associated with the wireless communication device and a value associated with an RNTI of the wireless communication device; and transmit or receive the control channel. Numerous other aspects are provided.

Abstract: Certain aspects of the present disclosure relate to communication systems, and more particularly, to techniques for time domain bundling of demodulation reference signals (DMRSs) in slot aggregation. An exemplary method generally includes detecting one or more conditions in at least one of a plurality of aggregated slots that indicate the at least one of the aggregated slots is not configured as a downlink-only slot, wherein each slot comprises a plurality of symbols, in response to the detection, determining whether to bundle demodulation reference signals (DMRSs) received across one or more of the aggregated slots, and performing channel estimation based on the determination.

Abstract: Certain aspects of the present disclosure provide techniques for performing, by a user equipment (UE), radio link monitoring based on discontinuous reception mode operation of the UE. Certain aspects provide a method for wireless communication. The method generally includes operating, at a user equipment (UE), in a discontinuous reception (DRX) mode of operation. The method further includes evaluating, by the UE, link quality between the UE and a base station (BS) at least once every time period, wherein the time period is based on a length of a DRX cycle of the UE operating in the DRX mode of operation and a reference signal (RS) period, wherein the BS is configured to transmit RS periodically every RS period.

Abstract: Certain aspects of the present disclosure provide techniques and apparats relating to designs for the remaining minimum system information (RMSI) control resource set (CORESET) and the other system information (OSI) CORESET. In certain aspects, a wireless communication device (e.g., user equipment) is enabled to determine the location of Type0-PDCCH common search space CORESET and the OSI CORESET in the frequency and time domains based on the location of the synchronization signal block (SSB) transmissions in the frequency and time domains. Determining the location of the RMSI CORESET and the OSI CORESET frequency and time resources enables the UE to receive the RMSI CORESET and the OSI CORESET, respectively.

Abstract: Certain aspects of the present disclosure relate to methods and apparatus mapping virtual resource blocks (VRBs) to physical resource blocks (PRBs) and using the mapping in wireless communications, for example, in new radio (NR) technologies. An exemplary method includes determining a first interleaved mapping that maps a first interleaving unit of N consecutive first virtual resource blocks (VRBs) to N consecutive first physical resource blocks (PRBs), wherein each first PRB comprises a set of frequency resources during a period, transmitting a first grant allocating the first interleaving unit of first VRBs to a first user equipment (UE), and communicating with the first UE via the first PRBs mapped to the first VRBs of the first interleaving unit.

Abstract: Aspects of the present disclosure describe determining an uplink channel raster for determining frequency location of an uplink channel over which to transmit uplink communications to a base station. Uplink communications can be transmitted to the base station over the uplink channel. The uplink channel raster can be shifted, in frequency, with respect to a legacy uplink channel raster of a legacy communication technology to facilitate coexistence, in an uplink carrier, of the uplink channel and one or more uplink channels of the legacy communication technology.

Abstract: Methods, systems, and devices for wireless communication are described. A base station may determine a group set of at least one synchronization signal (SS) block group to be transmitted within a SS burst set. The base station may identify a group transmission configuration index associated with the group set, and then transmit the group transmission configuration index to a user equipment. The base station may also include an indication of which SS blocks in each transmitted SS block group are transmitted. A user equipment (UE) may determine transmitted SS blocks based on the group set index or the indication of which SS blocks in each transmitted SS block group are transmitted.
