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： 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： A method and apparatus for accessing a wireless communication system, and for processing random access attempts. A mobile communication device detects random-access information transmitted by a base station, transmits a random-access preamble to the base station according to the random-access information, and receives a random-access response from the base station. The random-access response includes at least an allocation of uplink resources to be used for the next step in the random access procedure. The mobile device also selects a reference signal sequence index from a pre-determined set of sequence indexes, and transmits a first message to the base station using the uplink resource allocation provided in the random-access response. The first message includes a device identifier and a first demodulation reference signal derived from a base reference sequence shifted according to the selected sequence index.

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 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： 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.
