Abstract: A first wireless device receives, from a second wireless device and via a first time slot of a channel occupancy time (COT), a first sidelink transmission indicating COT sharing information of the COT. The first wireless device receives, from a third wireless device and via a second time slot of the COT, a second sidelink transmission indicating the COT sharing information of the COT. The first wireless device transmits, via a third time slot of the COT and in response to both the first sidelink transmission and the second sidelink transmission indicating the COT sharing information, a third sidelink transmission. Transmitting the third sidelink transmission is based on a first distance between the first wireless device and the second wireless device, and a second distance between the first wireless device and the third wireless device.

Abstract: A first wireless device determines a sidelink listen-before-talk (LBT) failure for a first resource block (RB) set, of RB sets of a first sidelink carrier of one or more sidelink carriers. The first wireless device starts a sidelink LBT failure detection timer for the first RB set. The first wireless device determines a consistent LBT failure for the first RB set based on a counter value of a sidelink LBT counter for the first RB set. The first wireless device determines a sidelink RLF detection for multiple destination identifiers associated with unicast service. Determining the sidelink RLF detection is based on a consistent LBT failure having been triggered in all RB sets of a sidelink resource pool configured in a first sidelink bandwidth part (BWP). The first wireless device releases multiple unicast links associated with the multiple destination identifiers.

Abstract: A video coder (encoder or decoder) generates, for a current block in a current frame, a list of merge candidates. A merge candidate in the list comprises decoder side intra mode derivation (DIMD) information associated with a spatially neighboring block of the current block. The coder further determines an indicator of the merge candidate in the list of merge candidates and codes the current block based on the DIMD information of the merge candidate in the list of merge candidates according to the indicator.

Abstract: A coder determines, based on illumination compensation being enabled for a reference block (RB), whether a first portion and a second portion of a current template of a current block (CB) is available. The first and second portions include samples of the current template to the left of and above the CB, respectively. Based on the determination of whether the first and second portions are available, a sampling pattern is determined for the current template of the current block and for a reference template of the RB. Values of parameters of a filter are derived based on the sampling pattern, available template samples of at least one of the first and second portions, and reference template samples of the reference template. The coder applies the filter to the RB to generate a prediction block and the current block is decoded based on the prediction block.

The video coder determines an indicator of the merge candidate in the list of merge candidates and codes the current block based on the DIMD information of the merge candidate in the list of merge candidates according to the indicator.

Abstract: A wireless device receives one or more radio resource control (RRC) configuration parameters. The RRC configuration parameters include a parameter indicating a timer to avoid triggering a random access (RA) procedure due to a beam failure recovery during an RA-based procedure for small data transmissions. The RRC configuration parameters indicate one or more preambles for the RA-based procedure.

The wireless device transmits a first preamble of the one or more preambles for the first RA-based procedure. While the first RA-based procedure is ongoing, the wireless device initiates a first RA procedure based on whether the timer is running and a received signal power being lower than a power threshold. The wireless device transmits a second preamble for the first RA procedure.
