    Abstract: A base matrix is applied to an LDPC coder. The base matrix includes multiple parts, each including multiple of rows and columns, and containing integers, each representative of an identity matrix cyclically shifted in accordance with the integer or representative of an all-zero matrix. At least two of the multiple parts are configured such that their respective column-wise combinations of rows represents a same starting vector, cyclically shifted or interleaved, with zero or more but not all integers not indicative of the all-zero matrix of the same vector substituted by integers indicative of the all-zero matrix. The at least two of the multiple parts are not identical. The applied base matrix is used for one of encoding data using the LDPC coder or decoding data using the LDPC coder.

    Abstract: Various communication systems may benefit from improved transmissions. For example, a network transmission may benefit from improved throughput and efficiency in non-schedule multiple access communications. A method includes selecting at a user equipment operating in a non-scheduled access scheme at least one of a first codeword or a second codeword based on an amount of data. The data in the non-scheduled access scheme can be spread according to a spreading sequence. The method also includes determining a transport block size for at least one of the first codeword or the second codeword. In addition, the method includes transmitting the data from the user equipment to a network node using at least one of the first codeword or the second codeword.

    Abstract: A method and apparatus to configure a resource pool for a plurality of user equipment configured with contention based transmission; configure a resource allocation within the resource pool for a contention based transmission by a user equipment of the plurality of user equipment configured for contention based transmissions, wherein the resource allocation is configured with more than one predefined or preconfigured sets of resource allocation granularities; and send information including the resource allocation towards the user equipment, wherein the information includes an indication of a set of the predefined or preconfigured sets of the resource allocation granularities that the user equipment is to use for the contention based transmission.
