Abstract: A method of performing contention resolution associated with a random access procedure includes transmitting, by the mobile communication terminal, a random access preamble; receiving, by the mobile communication terminal, a random access response; transmitting, by the mobile communication terminal, an uplink message and starting a contention resolution timer once the uplink message is transmitted; and receiving, by the mobile communication terminal, a physical downlink control channel (PDCCH), wherein the mobile communication terminal considers whether a contention resolution is successful or not by using either a cell radio network temporary identity (C-RNTI) on the PDCCH or a UE Contention Resolution Identity on a downlink shared channel (DL-SCH) associated with the PDCCH, wherein the mobile communication terminal considers the contention resolution successful and stops the contention resolution timer when the C-RNTI on the PDCCH matches the uplink message, and when the UE Contention Resolution Identity on the DL-SCH matches the uplink message.

Abstract: A method and terminal for use in a communication system are discussed. The terminal can transmit a random access preamble via a physical random access channel (PRACH) to a network. The terminal may monitor a random access response after transmitting the random access preamble during a specific time window. Furthermore, if no random access response containing a random access preamble identifier corresponding to the transmitted random access preamble is received within the specific time window and a specific random access response contains a backoff indicator subheader is received, a preamble transmission counter is incremented by 1. A subsequent random access preamble transmission is delayed by a backoff time selected using a backoff indicator in the backoff indicator subheader, if the random access preamble was selected by a medium access control (MAC) layer.

Abstract translation: 讨论了在通信系统中使用的方法和终端。 终端可以经由物理随机接入信道（PRACH）向网络发送随机接入前导码。 终端可以在特定时间窗口中发送随机接入前导码之后监视随机接入响应。 此外，如果在特定时间窗口内没有接收到包含与发送的随机接入前导码相对应的随机接入前同步码标识符的随机接入响应，并且接收到特定的随机接入响应包含后退指示符子报头，则前导码发送计数器增加1。 如果随机接入前导码是由介质访问控制（MAC）层选择的，随后的随机接入前同步码传输被延迟退避指示符子报头中使用后退指示符选择的回退时间。

Abstract: A method is described for operating a device in a wireless communication system. The device communicates with a base station using a subframe for the device only; detects, by the device, a problem with a connection between the device and the base station. The device starts a timer upon detecting the problem with the connection between the device and the base station. The device releases a restriction of using the subframe for the device only, if the timer expires. The problem with the connection between the device and the base station is associated with a radio link failure. The detection of a problem with the connection between the device and the base station comprises detecting consecutive out-of-sync indications.
