Embodiment Construction

[0040] As part of the development of the embodiments herein, problems with existing approaches will first be identified and discussed.

[0041] Assuming a maximum code block size, existing methods rely on the UE being able to store at least a portion of all code blocks in all HARQ processes. Under most operating conditions with a block error rate of 10-30%, there is a very small probability that all HARQ processes will require retransmission. Then, most soft buffers will not be used. Also, the UE cost will be unnecessarily high.

[0042] In addition, the following issues may also be identified in existing methods. First, soft buffers may not be shared across HARQ processes. That is to say, in the existing method, each HARQ process completes the division of the soft buffer, wherein each HARQ process is allocated a fixed number of CBs. Also, the entire TB is stored, including success and unsuccessful bits. If a given HARQ process requires more soft buffer memory for storage...

Abstract

A method performed by a wireless device (120) for handling a first transport block received from a transmitting device (101) is provided herein. The first transport block comprises a first set of codeblocks. At least a first subset of code blocks has been unsuccessfully decoded by the wireless device (120). The wireless device (120) and the transmitting device (101) operate in a wireless communications network (100). The wireless device (120) determines (802), based on a first number of unsuccessfully decoded code blocks, a second number of code blocks to be allocated in a first memory (1111)of the wireless device (120), to store the unsuccessfully decoded code blocks. The wireless device (120) also allocates (803) the determined second number of code blocks. The wireless device (120) then initiates (805) storage of the unsuccessfully decoded code blocks in the first set, in the allocated determined second number of code blocks.

Description

technical field [0001] The present disclosure generally relates to a wireless device and a method performed therefor for processing a first transport block received from a transmitting device. The present disclosure also generally relates to a transmission device and a method performed thereby for providing a first transmission block to a wireless device. Background technique [0002] A communication device within a wireless communication network may be a wireless device such as, for example, a station (STA), user equipment (UE), mobile terminal, wireless terminal, terminal and / or mobile station (MS). Enables a wireless device to communicate wirelessly in a cellular or wireless communication network (also sometimes referred to as a cellular radio system, cellular system or cellular network). It can be, for example, between two wireless devices, between a wireless device and a conventional phone, and / or between a wireless device and a server via a radio access network (RAN),...
