Embodiment Construction

[0051] In the following, an example of the method is described in the context of NR technology. However, these methods can also be considered for other RATs. The HARQ bits can be regarded as an example of acknowledgment information of sub-patterns of HARQ bits respectively. Typically, instead of a single HARQ feedback bit, a larger sub-pattern can be used. Also, communication between a network node and a UE is discussed by way of example. However, secondary link communication or backhaul communication between two UEs or two network nodes respectively may be considered.

[0052] The code block group will be described in more detail. If a transport block exceeds a certain size, the transport block may be fragmented or divided into multiple code blocks. For error detection, each code block as well as transport block may have its own CRC. In some cases, a single HARQ feedback bit may be generated per transport block. In addition, NR also supports Code Block Group (CBG) HARQ ...

Abstract

Disclosed is a method of operating user equipment 10 in a radio access network. The method comprises transmitting acknowledgement signaling based on a feedback configuration, the feedback configuration being selected from a set of configured acknowledgement configurations. The disclosure also pertains to related methods and devices.

Description

technical field [0001] The present disclosure relates to wireless or telecommunication communication technologies, in particular to radio access technologies eg for mobile communication. Background technique [0002] Currently, fifth-generation radio telecommunication technologies are being developed with the goal of serving a wide variety of use cases. Therefore, the related system must be very flexible. However, this flexibility introduces undesired signaling overhead. [0003] One area of ​​particular importance for many applications has to do with acknowledgment signaling procedures, which determine whether transmitted data has been correctly received or should be retransmitted. Examples of such processes include HARQ and ARQ processes. Contents of the invention [0004] It is an object of the present disclosure to propose a method allowing efficient (eg resulting in low signaling overhead) and flexible acknowledgment signaling. These methods are particularly advan...
