    • The embodiments herein relate to a method in a relay node (110) for relaying data from a first network node (107) to a second network node (101) in a radio communication network (100). The relay node (110)receives the data from the first network node (107) and decodes the received data. The relay node (110) determines a delay constraint of the decoded data and recodes the decoded data. The relay node (110) relays the recoded data to the second network node (101) based on the determined delay constraint and according to a radio communication protocol. The communication between the relay node (110), the first network node (107) and the second network node (101) is based on the same radio communication protocol.

    • A method in a first radio communication node (110, 310, 710, 1010) and a first radio communication node (110, 310, 710, 1010) for scheduling a data transmission in a first time frame using one of a plurality of modulation and coding schemes are provided. The data transmission is to be transmitted between the first radio communication node (110, 310, 710, 1010) and a second radio communication node (120, 320, 720, 1020). The first radio communication node (110, 310, 710, 1010) obtains (301, 701, 1001, 1401) a first indication about channel quality for the first time frame. The first radio communication node (110, 310, 710, 1010) obtains (302, 702, 1002, 1402) second indication about a possible upcoming transmission failure. The possible upcoming transmission failure relates to a feedback information to be transmitted in a second time frame. The feedback information is associated with the data transmission in the first time frame. The first radio communication node (110, 310, 710, 1010) selects (303, 703, 1003, 1403) a modulation and coding scheme out of said plurality of modulation and coding schemes based on the first indication and the second indication. Next, the first radio communication node (110, 310, 710, 1010) schedules (304, 704, 1004, 1404) the data transmission using the selected modulation and coding scheme.

    • A communication system node transmits first control channel information on a control channel that extends over a first bandwidth of a radiofrequency resource. The first control channel information is necessary to enable a first type of communication device, capable of receiving a signal having the first bandwidth, to establish a connection with a host cell. A MIB, occupying a second bandwidth-size part of the first bandwidth, is transmitted. The second bandwidth is smaller than the first bandwidth and is receivable by a second type of communication device having reduced receive bandwidth capabilities. The MIB has a first part comprising first part information necessary to enable the first type of communication device to establish the connection with the host cell, and a second part comprising second part information directly or indirectly enabling the second type of communication device to obtain parameters that enable connection establishment with the host cell.

    • A communication device has a plurality of concurrently operating transceiver systems, each operating in a respectively different one of a plurality of communication systems. Operation of the transceiver systems is coordinated by receiving a plurality of requests from different ones of the transceiver systems, each of the requests being a request to access a communication medium for the purpose of transmitting or receiving a data packet. Utilization of an available time period is scheduled by selecting which one or ones of the requests to grant based, at least in part, on how many remaining times out of a maximum number of times each of the transmission systems' data packet is permitted to be retransmitted compared to other requests, on whether the requests are requests to transmit a data packet, and on whether the requests are requests to receive a data packet.
