    Abstract: Various techniques are presented to improve channel estimation in a wireless system, comprising: receiving, by a wireless device, an indication of a physical downlink channel configuration for receiving a physical downlink channel transmission, the physical downlink channel transmission including a demodulation reference signal (DMRS); transmitting an indication that the wireless device supports bundling DMRS signals across multiple slots; receiving a DMRS configuration, the DMRS configuration including a channel estimation bundle window, the channel estimation bundle window indicating that channel estimation may be performed across multiple slots; receiving a set of DMRS signals within the channel estimation bundle window, wherein a first DMRS signal of the set of DMRS signals is received in a first slot, and wherein a second DMRS signal of the set of DMRS signals is received in a second slot; and estimating a radio channel based on the first DMRS signal and the second DMRS signal.

    Abstract: Switching schemes at a mobile device may include, in response to being within range of a transmission and reception point (TRP) of a plurality of TRPs associated with a high speed train (HST), decoding a communication received from a network. The communication may include a first radio resource control (RRC) information element (IE) having an HST configuration associated with an HST scheme. The HST configuration may be applied to thereby operate using the HST scheme. In response to being out of range of the plurality of TRPs associated with the HST, a communication received from the network may be decoded. The communication may include a second RRC IE having a non-HST configuration associated with a non-HST scheme. The non-HST configuration may be applied to thereby operate using the non-HST scheme.

    Abstract: In an example method, a user equipment (UE) device receives, from one or more base stations (BSes), Downlink Control Information (DCI) including scheduling information for receiving a plurality of Physical Downlink Shared Channels (PDSCHs) from the BSes. The UE device determines a pre-determined time subsequent to a reception of a sequentially last symbol of the DCI, and determines (i) a first subset of the PDSCHs scheduled for reception prior the pre-determined time, and (ii) a second subset of the PDSCHs scheduled for reception subsequent to the pre-determined time. The UE device determines one or more Transmission Configuration Indicator (TCI) states that indicate a quasi co-location (QCL) for a plurality of antenna ports of the one or more PDSCHs that are transmitted by the BSes. Further, the UE device processes the first subset of the PDSCHs and the second subset of the PDSCHs according to the determined TCI states.
