The wireless device may also monitor, in a second DRX on duration of the second DRX configuration and while skipping monitoring the first PDCCHs in the first DRX on duration, second PDCCHs for the MBS.

Abstract: An encoder or decoder projects, in an angular direction, a location of a sample in a block to a point on a reference line between a plurality of reference samples. The encoder or decoder selects a filter coefficient table, from among a plurality of filter coefficient tables, based on the angular direction and a size of the block. The encoder or decoder selects first filter coefficients from the filter coefficient table based on a fractional part of a displacement of the point on the reference line relative to the location of the sample. The encoder or decoder applies, to the plurality of reference samples, the first filter coefficients to determine a first filtered value. The encoder or decoder determines a prediction of the sample based on the first filtered value.

Abstract: A current block may be encoded/decoded based on a reference block flipped relative to the current block. An indication of whether a value of a parameter (e.g., a block vector difference) indicating the reference block matches a value of a predictor for the parameter (e.g., a block vector difference predictor) may be entropy encoded. The predictor may be selected from among a plurality of candidates based on costs associated with the plurality of candidates associated with candidate reference blocks. The cost of each candidate may be based on comparisons between a template of a current block and templates of the candidate reference blocks, where the templates of the candidate reference blocks have a shape flipped relative to that of the current block.
