摘要： A method for a wireless communications network for data packet including a user equipment (UE) and a transceiver node (eNodeB). The user equipment (UE) and the node (eNodeB) intercommunicate over an air interface communication link. The user equipment (UE) transmits a first message (MSG3) in a first scheduled transmission in a random access procedure during setup of the communication link. The first message is transmitted in a first sub frame (TTI=3) and in a second sub frame (TTI=4; TTI=5) within a first roundtrip time (RTT) in a first HARQ- process triggered by the transmission of the first message in the first sub frame (TTI=3).

摘要： The present invention relates to receiving access signals from a plurality of terminals over a radio channel and in particular to determining a detection threshold level on the radio channel. A detection threshold level should balance the risk of missed detections to the risk of false detections. A problem in finding an equilibrium threshold is the radio environment, with noise and interference, change and then also the radio false detections or missed detections change. According to the present invention some access signals can be identified as being not assigned and therefore not being in use, and any detection of a non-used signal is identified as a false detection. By monitoring the ratio of false detections vs. correct detections the threshold level for detection is tuned into an equilibrium level, and that is adapted to the changing radio environments. In addition the detection threshold level for access signals detection threshold for data and/or control signalling may be adjusted in relation to the access signal threshold level.

摘要： The disclosure relates to methods and devices for performing uplink power control in a radio communication system. An example method comprises a step of receiving, at a user equipment (UE) a transmit power control (TPC) command. The method also comprises, if the UE does not have an uplink transmission scheduled for a subframe associated with the TPC command, a step of accumulating, by the UE, the TPC command with previously received TPC commands based on whether the UE has reached a maximum transmit power or a minimum transmit power in a reference format for a Physical Uplink Shared Channel (PUSCH), Sounding Reference Signal (SRS) or Physical Uplink Control Channel (PUCCH) transmission. Thus the UE is enabled to receive TPC commands while the UE is not transmitting anything in the uplink.
摘要翻译：本公开涉及用于在无线电通信系统中执行上行链路功率控制的方法和装置。一种示例性方法包括在用户设备（UE）处接收发射功率控制（TPC）命令的步骤。该方法还包括：如果UE没有针对与TPC命令相关联的子帧进行调度的上行链路传输，则UE基于UE是否达到最大值，先前接收到的TPC命令累积TPC命令的步骤用于物理上行链路共享信道（PUSCH），探测参考信号（SRS）或物理上行链路控制信道（PUCCH）传输的参考格式的发射功率或最小发射功率。因此，当UE不在上行链路中传输任何内容时，UE能够接收TPC命令。

摘要： The technology described in this case facilitates random access by a user terminal with a radio base station. A user terminal determines one of a first type of uplink scrambling sequences and generates a random access message using the determined one of the first type of uplink scrambling sequences. The random access message is transmitted to the base station. The user terminal receives from the base station a second, different type of uplink scrambling sequence and uses it for subsequent communication with the radio base station. For example, the first uplink scrambling sequences may be specifically associated with the radio base station's cell area or a random access radio channel associated with the radio base station, but they are not specifically assigned to any user terminal, and the second uplink scrambling sequence may be selected from a second set of uplink scrambling sequences specifically assignable to individual user terminals.

摘要： A solution for extending the cell range and in particular for a solution for handling timing alignment is presented herein. The solution comprises determining a distance between user equipment and a radio access network node. User equipment located at a distance related to a pre defined timing advance value is scheduled to handle uplink communication so as to arrive at a later time slot for reducing the risk of conflicting with other transmissions towards the access node.

摘要： In order to provide a more robust contention-free random access procedure for use in a cellular wireless network and specifically, a contention-free random access procedure that is able to recover more quickly in case of failure a method for a radio access node (10) that is arranged in a wireless network and communications with user equipment, UE (20) and a radio access node are proposed. The method includes: receiving a first random access message (40) from a UE, the first message containing a pre-assigned contention-free random access preamble and representing a start of a random access procedure; responding to the received first message by sending a second message (50) to the UE, the second message containing time alignment information to enable a scheduled transmission of a third message (60) by the UE; ascertaining that no third message is received from the UE within a predetermined period of time and transmitting a command (80) to the UE ordering a restart of the random access procedure with the same pre-assigned contention-free random access preamble.

摘要： The invention discloses a method (400) for use in a first node (110) in a wireless access communication system (100). According to the method, the first node controls (405) traffic to and from users, UEs (120), within a certain area in the system, a cell, and the first node is equipped (410) with a plurality of transmit antennas (111,113). The first node can employ (415) a variety of multi antenna transmit modes for down link transmissions, i.e. transmissions to the UEs, and the first node can carry (420) out a so called Random Access (RA) procedure with UEs which do not have a dedicated up link resource, i.e. a resource to the eNodeB. According to the method, one and the same down link multi antenna transmit mode is used by the first node during the RA procedure.
