Abstract: There is provided mechanisms for random access. A method is performed by a wireless device. The method comprises transmitting a random access preamble to a network node. The method comprises determining a valid starting subframe of a random access response window for monitoring a common search space for a random access response from the network node. Starting time of the random access response window is adapted such that it starts with the valid subframe. The method comprises monitoring the common search space for the random access response only during the random access response window.

Abstract: There is provided a method, a user equipment and a base station that is capable of enhancing network throughput by efficiently transmitting E-DCH HARQ Acknowledgement Indicator Channel (E-HICH) information in the radio network. The method comprises combining previous E-HICH information with current E-HICH information when a transmission interval of the previous E-HICH information fully overlaps with a compressed mode gap, and transmitting the combined E-HICH information in a transmission interval of the current E-HICH information. The UE is configured to transmit uplink data even if it is determined that the E-HICH information of the uplink data will not be received before a next uplink transmission interval. Both the previous E-HICH information and the current E-HICH information will be received in the transmission interval of the current E-HICH information. Therefore, the network throughput is effectively enhanced.
