    摘要： According to some embodiments, a method for use in a wireless transmitter of a wireless communication network comprises encoding information bits using a parity check matrix (PCM) and transmitting the encoded information bits to a wireless receiver. The partly check matrix (PCM) is optimized according to two or more approximate cycle extrinsic message degree (ACE) constraints. In some embodiments, a first portion of the PCM is optimized according to a first ACE constraint and a second portion of the PCM is optimized according to a second ACE constraint.

    摘要： A method in a communication system comprising a radio device and radio access network node, the method comprising and/or initiating a step of setting, in the radio device, a length of a transmission time interval (TTI) in a physical uplink control channel; a step of transmitting control information, by the radio device, over the physical uplink control channel with the set transmission time interval length; and a step of changing the transmission time interval length to be set by said radio device based on a channel or payload characteristic between said radio device and said radio access network node.

    摘要： Systems and methods for adapting a timer(s) for a satellite-based radio access network are disclosed. Embodiments of a method performed by a user equipment or a base station and corresponding embodiments of a user equipment or a base station are disclosed. In some embodiments, a method performed by a user equipment or a bases station comprises obtaining an amount of resources elements available and determining a transport block size based on the amount of resources elements available. In some embodiments, repetitions are used. In some embodiments, obtaining the available resource elements amount is based on at least one of: one or more explicit calculations and/or one or more signaled scaling factor(s). In some embodiments, the method further comprises determining (or selecting) a modulation and code rate (MCS) based on the amount of resources elements available.
