Problems solved by technology

If a strong access burst (AB) from a first wireless device close to the BTS collides with a weak AB from a second wireless device far away from the BTS, then the second wireless device far away from the BTS The device will likely not be able to connect to the network
A further drawback of the design described in EC-EGPRS is therefore that accessing the network will be challenging for wireless devices in extended coverage due to the multiplexing on EC-RACH with wireless devices in normal coverage

Embodiment Construction

[0053] As part of the examples developed herein, some issues with the state of the art communication networks will first be identified and discussed.

[0054] It is foreseen that the radio access network will be overwhelmed by connected devices (eg connected wireless devices). For example, it is foreseen that the radio access network will have 50 billion connections by 2020. The common control channel thus runs the risk of being overloaded. In said UL, both the legacy RACH (eg CCCH UL TS0 ) and the new EC-RACH (eg EC-CCCH UL TS1 ) have the risk of becoming overloaded, and if the load between these two channels is unbalanced, The risks then become more pronounced, one of them becoming a bottleneck. The same is true in the DL, where legacy AGCH and EC-AGCH, and legacy PCH and EC-PCH channels will be exposed to the expected increase in connected devices. The load can change rapidly because no longer only the number of wireless devices is important to the load of the channel, b...

Abstract

A radio network node RNN (106) and method therein for load balancing in a wireless communication network (100). The RNN is configured to communicate with a wireless device (108) supporting both normal and extended coverage. The RNN and the wireless device are operating in the wireless communication network. The RNN determines an indication that informs the wireless device that it is to monitor one of downlink legacy resources and extended coverage resources for information while in normal coverage, and / or when accessing the wireless communication One of the uplink legacy resource and the extended coverage resource is used when the network is connected. Further, the RNN transmits the indication to the wireless device.

Description

technical field [0001] Embodiments herein relate generally to wireless devices, radio network nodes, network nodes, and to methods therein. In particular, embodiments herein relate to load balancing in wireless communication networks. Background technique [0002] A communication device such as a terminal is also known as eg user equipment (UE), mobile terminal, station (STA), wireless device, wireless terminal and / or mobile station (MS). Enables terminals to communicate wirelessly in a cellular communication network or wireless communication system (sometimes also referred to as a cellular radio system or cellular network). This communication may be, for example, between two terminals, between a terminal and a conventional telephone, and / or between a terminal and a server, possibly via one or more core networks comprised within said cellular communication network and via radio interfaces. into the network (RAN) to be executed. [0003] Just to mention some further exampl...
