Problems solved by technology

Therefore, when the actual number of OFDM symbols available for PDSCH deviates from the assumed 11 OFDM symbols, this assumption may lead to mismatch problems, which in turn will reduce the data throughput

Embodiment Construction

[0078] The figures are schematic and simplified for clarity, and they only show details necessary for understanding the embodiments, while other details are omitted. Throughout, the same reference numerals are used for the same or corresponding parts or steps.

[0079] As a development of the embodiments described herein, one problem will first be identified and discussed.

[0080] In some scenarios, it has been noted that one way of dealing with apparent mismatch of OFDM symbols in TDD special subframes has been introduced into the standard specification 3GPP TS 36.213 "Physical Layer Procedures".

[0081] Typically, for a downlink subframe, the user equipment first calculates the total number of allocated PRBs. The total number of allocated PRBs is based on the PRB resource allocation included in the downlink control and the procedures provided in the standard specification 3GPP TS 36.213 "Physical Layer Procedures". The total number of allocated PRBs is denoted as N' PRB...

Abstract

A method in a user equipment (121) for determining a transport block size is provided. The transport block size is used by the user equipment (121) in receiving downlink data transmissions from a network node (110) on an enhanced Control CHannel, eCCH. The user equipment (121) and the network node (110) are comprised in a telecommunications system (100). The user equipment (121) has access to a table of predetermined transport block sizes. The user equipment (121) may calculate an indicator NuPRB based on the total number of PRBs allocated to the downlink data transmission NPRB, and based on a PRB offset value OPRB or a PRB adjustment factor APRB. Then, the user equipment (121) may determine the transport block size from the table of predetermined transport block sizes based on at least the calculated indicator NPRB. A user equipment, a method in network node and a network node are also provided.

Description

technical field [0001] Embodiments herein relate to network nodes, user equipment and methods therein. In particular, embodiments herein relate to determining a transport block size for downlink transmissions in a telecommunications system. Background technique [0002] In today's radio communication networks, a variety of different technologies are used, such as Long Term Evolution (LTE), LTE-Advanced, Wideband Code Division Multiple Access (WCDMA), Global System for Mobile Communications / Enhanced Data Rates for GSM Evolution (GSM / EDGE), Worldwide Interoperability for Microwave Access (WiMax), or Ultra Mobile Broadband (UMB), to mention just a few possible technologies for radio communications. A radio communication network comprises radio base stations providing radio coverage over at least one respective geographical area forming a cell. The cell definition can also incorporate the frequency band used for transmission, which means that two different cells can cover the...
