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.

摘要： A method (500) for use in a user terminal (120, 130) in a cellular communications system (100). According to the method, the user terminal applies a first timing advance value (505) to its transmissions to a controlling node (140), and the user terminal (120, 130) requests communication with the controlling node (140) in a contention based procedure by transmitting an access request (MSG 1), in response (515) to which the controlling node transmits an initiation message (MSG 2) along with (520) a second timing advance value. According to the method (500), the user terminal (120, 130) uses (530) the first timing advance value if the user terminal loses the contention based procedure, i.e. if the controlling node subsequently continues the initiated communication with said other user terminal.

摘要： A method in a base station for controlling a Random Access, RA, procedure is provided. The base station initiates (201) an RA procedure on a Secondary Cell, SCell, in a User Equipment, UE, by sending to the UE a Physical Downlink Control Channel, PDCCH, order for a RA procedure on the SCell. At initiation of RA, the base station starts (202) a timer in the base station. The timer is a timer for random access failure detection associated with said initiated RA procedure. If the RA procedure has not been completed before expiry of said timer, the base station sends (205) a command to the UE, commanding the UE to deactivate the SCell, and thereby stopping the RA procedure on the SCell.

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： 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： 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.
