    Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may receive, from a base station, configuration information including multiple transmission configuration indication (TCI) states associated with a control resource set (CORESET). The UE may receive, from the base station, a physical downlink control channel (PDCCH) in a region associated with the CORESET, wherein the PDCCH includes at least one control channel element (CCE). The UE may perform blind decoding for multiple configured PDCCH candidates based at least in part on a resource element group (REG) bundle included in the at least one CCE, wherein the multiple configured PDCCH candidates are associated with one or more of the multiple TC states associated with the CORESET. Accordingly, the UE may identify the PDCCH transmitted by the base station based at least in part on the blind decoding.

  • Publication number: 20210235455
    Abstract: Example implementations include a method, apparatus and computer-readable medium of wireless communication. A user equipment (UE) may receive a downlink control information (DCI) indicating two or more transmission configuration indication (TCI) states for a physical downlink shared channel (PDSCH). The UE may differentiate that the two or more TCI states apply to all demodulation reference signal (DMRS) ports or all transmission layers across all resource blocks and symbols for the PDSCH from TCI states that apply to different sets of DMRS ports or different sets of resource blocks or symbols. The UE may generate a composite quasi-co-location (QCL) based on the two or more TCI states in response to the differentiating. The UE may receive the PDSCH based on the composite QCL.

  • Publication number: 20210226833
    Abstract: Aspects of the disclosure relate to wireless communication networks having a capability of controlling the mapping of reference signals onto a carrier based on one or more Doppler parameters. A demodulation reference signal (DMRS) is mapped to a carrier according to a pattern based on one or more Doppler parameters, such as a Doppler frequency and/or a rate of change of channel conditions. In a further example, if an initial transmission of an information packet fails due to a high Doppler scenario, the probability of success of the retransmission may be improved by altering the DMRS configuration to account for the high Doppler scenario. Other aspects, examples, and features are also claimed and described.

  • Publication number: 20210226820
    Abstract: Methods, systems, and devices for wireless communications are described. In some systems, a base station may transmit to a user equipment (UE) over a control channel (e.g., a downlink control channel) and the UE may monitor for the control channel in a control resource set (COREST). The control channel and the CORESET may be associated with a set of transmission configuration indicator (TCI) states. The base station and the UE may identify an association between the resources of the CORESET and the set of TCI states based on a frequency division multiplexing (FDM) mapping between the resources of the CORESET and the set of TCI states. In some examples, the association may be a fixed rule at the UE. In other examples, the base station may signal the association to the UE via control signaling. The UE may decode the control channel based on the FDM mapping.

  • Publication number: 20210226754
    Abstract: Methods, systems, and devices for wireless communications are described. A control resource set (CORESET) may be configured to support multiple transmission configuration indicator (TCI) state control channels. Space division multiplexing (SDM) may be implemented to enable multi-TCI states by using multiple ports and layers. A certain layer and demodulation reference signal (DMRS) port may be associated with a certain TCI state. For orthogonal ports, resources elements (REs) may be assigned such that a first set of REs are assigned to the first DMRS port and a second set of REs are assigned to the second port. The multiple DMRS ports may be code division multiplexed (CDM'd) within an RE such that multiple DMRS ports may be associated with the same RE. For non-orthogonal ports, the same RE may be used for multiple TCI states, where scrambling sequences may be applied to DMRSs associated with the TCI states.

  • Publication number: 20210227525
    Abstract: Methods, systems, and devices for wireless communications are described. In some wireless communications systems, a base station may transmit a control channel such as a PDCCH using one or more control resource sets (CORESETs). A CORESET may be associated with a number of different transmission configuration indicator (TCI) states which may specify information that a UE may use to receive the PDCCH. In some cases, the UE may identify an association between resources of the CORESET and a number of TCI states assigned to a CORESET using various different multiplexing techniques, such as time division multiplexing (TDM). Some associations between the resources of the CORESET and the TCI states may include a mapping of the resources of the CORESET to the different TCI states. The UE may decode the PDCCH based on the different TDM techniques used to configure the CORESET.
