Problems solved by technology

Another approach could be to use a very different format of the MIB-NB depending on the uplink-downlink TDD configuration, but the different formats increase the complexity of the radio, which is at least in some deployments different from that of NB-IoT UEs. Slim design goes against

Embodiment Construction

[0042] In the following description, for purposes of explanation and not limitation, specific details such as a particular network environment are set forth in order to provide a thorough understanding of the techniques disclosed herein. It will be apparent to those skilled in the art that the technology may be practiced in other embodiments that depart from these specific details. Furthermore, although the following embodiments are described primarily for 5G New Radio (NR) implementations, it is readily apparent that the techniques described herein may also be implemented in any other radio network, including 3GPP LTE or its successors, according to Wireless Local Area Network (WLAN) of the standards family IEEE 802.11, Bluetooth (in particular Bluetooth Low Energy and Bluetooth Broadcast) according to the Bluetooth Special Interest Group (SIG) and / or ZigBee based on IEEE802.15.4.

[0043] In addition, those skilled in the art will understand that the functions, steps, units ...

Abstract

A technique for transmitting system information for a time-division duplex, TDD, communication in a radio access network, RAN, is described. As to a method aspect of the technique, a master information block, MIB, is transmitted on an anchor carrier (602-1) of the TDD communication in the RAN. The MIB is indicative of a spectral resource (602-1; 602-2) allocated to a system information block, SIB,of the TDD communication in the RAN. The SIB is transmitted on the spectral resource (602-1; 602-2) indicated in the MIB.

Description

technical field [0001] This disclosure generally relates to techniques for transmitting and receiving system information. More particularly, methods and apparatus for transmitting and receiving system information blocks in a radio access network are provided. Background technique [0002] A radio accesses the RAN by scanning certain radio carriers for system information elements and time synchronization signals necessary to access the Radio Access Network (RAN). Examples of such radio devices include Mobile Broadband (MBB) devices such as User Equipment (UE) according to 3rd Generation Partnership Project (3GPP) Long Term Evolution (LTE) and Narrowband (NB) devices such as 3GPP NB IoT ( NB-IoT) UE). An example of basic system information includes a Master Information Block (MIB) for 3GPP systems. The carrier that facilitates the initial synchronization of NB-IoT UEs is called an anchor carrier. [0003] Similar to existing LTE UEs, NB-IoT UEs are only required to search ...
