Abstract: A decoder receives, from a bitstream for a video, an indication of a block vector predictor (BVP) for a block vector (BV). Each of the BV, the BVP, and a block vector difference (BVD) associated with the BV and the BVP has two components in two respective directions. The decoder determines a sign of a component of the BVD in one direction of the two directions based on: a component of the BV in the other direction of the two directions, and a component of the BVP in the one direction. The decoder further decodes the BV based on the BVP and the BVD determined based on the sign, and generates, based on the BV, an intra block compensated prediction of a current block. The decoder decodes the current block based on the intra block compensated prediction and a residual of the current block.

Abstract: An access point (AP) multi-link device (MLD) transmits to a non-access point (non-AP) MLD, on a first link, a first frame scheduling a restricted target wake time (r-TWT) service period (SP) of a r-TWT setup for the non-AP MLD on the first link. The AP MLD transmits to the non-AP MLD, on a second link, a second frame for scheduling traffic associated with the r-TWT on the second link. The transmitting of the second frame may be responsive to a failure by the AP MLD to schedule the traffic associated with the r-TWT during the r-TWT SP on the first link.
