摘要： Embodiments of the present disclosure relate to methods and apparatuses for resource allocation in vehicle to everything (V2X) communication. According to an embodiment of the present disclosure, a method may include: determining resource allocation information indicating at least one set of resources for a set of transport blocks; and transmitting the determined resource allocation information. Each set of resources is associated with a transport block of the set of transport blocks to be transmitted on sidelink. Each set of resources may include: a plurality of sidelink transmission resources, each sidelink transmission resource being configured to carry a sidelink transmission of the transport block; a plurality of sidelink feedback resources, each sidelink feedback resource being configured to carry sidelink feedback information in response to the sidelink transmission of the transport block; and a plurality of uplink feedback resources, at least one of the plurality of uplink feedback resources being configured to carry uplink feedback information in response to the sidelink transmission of the transport block only in the case that the sidelink feedback information represents that the transport block has been successfully decoded.

摘要： The present application is related to a method and apparatus of using redundant bits in semi-statically configured HARQ-ACK feedback. A method of receiving information according to one embodiment comprises receiving a first number of code block groups from a base unit, wherein each code block within a code block group is independently decodable; determining a (HARQ-ACK) codebook size corresponding to the first number of code block groups; and transmitting a HARQ-ACK codebook to the base unit, wherein the HARQ-ACK codebook comprises the first number of HARQ-ACK bits with each bit corresponding to one code block group and a second number of padded bits. The first number plus the second number is equal to the determined HARQ-ACK codebook size. The present application enhances the downlink (DL) transmission performance and the uplink (UL) HARQ-ACK transmission reliability.

摘要： Apparatuses, methods, and systems are disclosed for encoding reference signal received powers. One apparatus (200) includes a processor (202) that: determines (402) a reference signal received power corresponding to each beam of multiple beams to result in a set of determined reference signal received powers; orders (406) the set of determined reference signal received powers in descending order to result in an ordered list of reference signal received powers; and encodes (408) a difference between each two adjacent reference signal received powers of the ordered list of reference signal received powers to result in an encoded ordered list of reference signal received powers.
