Abstract
Technology for user equipment (UE) operable for physical downlink shared channel (PDSCH) repetition communication is disclosed. The UE can comprise one or more processors configured to: decode information from a first transmission from a PDSCH and information from one or more repeated transmissions from the PDSCH; decode a repetition parameter value; and determine whether a first transmission configuration indicator (TCI) state for the first transmission and one or more additional TCI states for the one or more repeated transmission are different based on the repetition parameter value.
Claims19
An apparatus of a user equipment (UE) operable for physical downlink shared channel (PDSCH) repetition communication, the apparatus comprising:
- one or more processors configured to:
- activate, at the UE, specified transmission configuration indicator (TCI) states based on medium access control (MAC) signaling received at the UE;
- receive, at the UE, in downlink control information (DCI), a single value configured to indicate a usage of a plurality of the specified TCI states to receive PDSCH repetitions;
- determine, at the UE, based on the single value in the DCI, to cycle through the plurality of the specified TCI states to receive the PDSCH repetitions;
- and
- receive, at the UE, the PDSCH repetitions by cycling through the plurality of the specified TCI states;
- and
- a memory interface configured to store the single value in a memory.
An apparatus of a base station operable for physical downlink shared channel (PDSCH) repetition communication, the apparatus comprising:
- one or more processors configured to:
- signal, to a user equipment (UE), specified transmission configuration indicator (TCI) states via medium access control (MAC) signaling;
- send, to the UE, a single value in downlink control information (DCI), the single value configured to indicate to the UE to cycle through a plurality of the specified TCI states to receive PDSCH repetitions;
- and
- send, to the UE, the PDSCH repetitions;
- and
- a memory interface configured to store the single value to a memory.
A method of a UE, comprising:
- activating, at the UE, specified transmission configuration indicator (TCI) states based on medium access control (MAC) signaling received at the UE;
- receiving, at the UE, in downlink control information (DCI), a single value configured to indicate a usage of a plurality of the specified TCI states to receive PDSCH repetitions;
- determining, at the UE, based on the single value in the DCI, to cycle through the plurality of the specified TCI states to receive the PDSCH repetitions;
- and
- receiving, at the UE, the PDSCH repetitions by cycling through the plurality of the specified TCI states.
