Embodiment Construction

[0065] the term

[0066] The following general terms are used in the examples and described in detail below:

[0067] Radio Network Node: In some embodiments, the non-limiting term radio network node is more commonly used, and it refers to any type of network node that serves a UE and / or connects to other network nodes or network elements or that a UE can Any radio node from which a signal is received. Examples of radio network nodes are Node Bs, base stations (BS), multi-standard radio (MSR) radio nodes such as MSR BSs, eNode Bs, network controllers, radio network controllers (RNCs), base station controllers, repeaters, Donor nodes control repeaters, base transceiver stations (BTS), access points (APs), transmission points, transmission nodes, remote radio units (RRU), remote radio heads (RRH), distributed antenna systems (DAS) nodes etc.

[0068] Network node: In some embodiments the more general term "network node" is used and may correspond to any type of radio network ...

Abstract

The present invention provides a method performed by a first communication device (101) for sending one or more control signals to a second communication device (102). The first communication device (101) and the second communication device (102) operate in a wireless communications network (100). The first communication device (101) determines (901), during a first period, that a transmission medium is available for sending the one or more control signals to the second communication device (102). The first communication device (101) then sends (902), to the second communication device (102),the one or more control signals along with a discovery signal, via the transmission medium. The discovery signal and the one or more control signals are sent without data after the first period. The first period is shorter than a second period for determining that the transmission medium is available for sending the data.

Description

technical field [0001] Embodiments herein relate to a first communications device and methods therein for sending one or more control signals to a second communications device. Embodiments herein also relate to a computer program and a computer-readable storage medium having stored thereon a computer program for performing these methods. Background technique [0002] A communication device such as a terminal is also called eg User Equipment (UE), mobile terminal, wireless terminal, wireless device and / or mobile station. Terminals are capable of communicating wirelessly in a cellular communication network or wireless communication system (also sometimes referred to as a cellular radio system or cellular network). Communications may be performed, for example, between two terminals, between a terminal and a regular telephone and / or between a terminal and a server via a radio access network (RAN) and possibly one or more core networks included within a cellular communication ne...
