Problems solved by technology

For the use of coverage enhancement (i.e. repetition), it takes additional time to receive segments, which adds some additional challenges to receive all segments within the repetition period of SC-MCCH, even when the current legacy values ​​for the repetition and modification periods This is also the case with the possible extension

Embodiment Construction

[0049] The embodiments set forth below present information to enable those skilled in the art to practice the embodiments and show the best mode for practicing the embodiments. After reading the following description in light of the accompanying drawing figures, those skilled in the art will understand the concepts of the disclosure and will recognize applications of these concepts not specifically addressed herein. It should be understood that these concepts and applications fall within the scope of the present disclosure.

[0050] In the current Single Cell Point-to-Multipoint (SC-PTM) for legacy Long Term Evolution (LTE) transmissions, the maximum transport block size (TBS) is large enough that there is no need for a Single Cell Multicast Control Channel (SC-MCCH) The payload is segmented. However, TBS is reduced for Narrowband Internet of Things (NB-IoT) and Enhanced Machine Type Communication (eMTC) compared to legacy LTE. As such, the size of the SC-MCCH message may ex...

Abstract

Systems and methods relating to scheduling and transmitting / receiving a segmented Single-Cell Multicast Control Channel (SC-MCCH) are disclosed. In some embodiments, a method of operation of a wireless device to receive a plurality of SC-MCCH segments comprises obtaining information regarding segmentation of a SC-MCCH into a plurality of SC-MCCH segments and receiving, from a network node, separate transmissions for the plurality of SC-MCCH segments in accordance with the information regarding segmentation of the SC-MCCH. By segmenting the SC-MCCH in this manner, increasing the maximum Transport Block Size (TBS) or defining a higher TBS size for SC-MCCH can be avoided.

Description

[0001] related application [0002] This application claims priority to Provisional Patent Application 62 / 449,294, filed January 23, 2017, the disclosure of which is incorporated herein by reference in its entirety. technical field [0003] The present disclosure relates generally to wireless communications, and more particularly to segment scheduling for a Single Cell Multicast Control Channel (SC-MCCH). Background technique [0004] Recently, a lot of work has been done in the 3rd Generation Partnership Project (3GPP) related to specifying technologies covering machine-to-machine (M2M) and / or Internet of Things (IoT) related use cases. Recent work on 3GPP Release (Rel) 13 includes enhancements to support Machine Type Communication (MTC) with the new User Equipment (UE) Category M1 (Cat-M1), which supports a reduction to a maximum of six Physical Resource Blocks (PRBs) ), recent work also includes a narrowband IoT (NB-IoT) work item specifying a new radio interface and UE ...
