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 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 a user terminal (120, 130) in a cellular system (100). The user terminal (120, 130) applies (505) a timing advance to transmissions to a controlling node (140). The user terminal (120, 130) requests (510) communication with the controlling node (140) by a special message (MSG 1), in response to which the user terminal (120, 130) receives (515) a message (MSG 2) which includes an updated value for the timing advance. The user terminal (120, 130) compares (520) the updated value with the value of the timing advance that the user terminal had prior to the reception of said response message. If the difference (Δ) between the prior value and the updated value is greater than a first predetermined threshold (T1) or below a second predetermined threshold (T2), the user terminal (120, 130) ignores (525) the response message (MSG 2) and renews its request for communication.

摘要： A method and a system are disclosed for avoiding inter-layer inter-symbol interference. Diagonally layered multi-antenna transmissions are utilised by the proposed method and system. Known symbols are inserted at the borders between different layers to avoid inter-layer inter-symbol interference. The system relies on an improved method to transmit multiple data-streams (layers). The invention describes a method for transmitting data-streams over multiple antennas in an effective and smart way when having frequency selective channels. By utilising a system using the present method problems with inter-layer inter-symbol interference between different data-streams can be avoided when changing transmit antenna for the data-streams. The invention utilises that a diagonal layered multi-antenna transmission will not create inter-symbol interference, ISI, between different layers.

摘要： A method and apparatus for determining the content in bursts (312) to be transmitted from a base station (300a) in a mobile network on a broadcast frequency (314) in specific timeslots of a broadcast frequency frame structure. A current state of the logical channel allocated to the forthcoming burst is checked (502), and the content in the forthcoming burst is determined depending on the current channel state. A dummy burst with a base station specific training sequence is transmitted if there is no data to transmit, and if the dummy burst cannot be confused with a regular traffic burst according to the current channel state. The dummy burst contains no intelligible information to mobile terminals.

摘要： A base station transmits data blocks in downlink sub-frames to a terminal and receives feedback reports for the data blocks in uplink sub-frames from the terminal. The feedback reports indicate whether errors have occurred in the data blocks and are scheduled in the uplink sub-frames according to a predetermined spreading rule known by the base station and the terminal. The spreading rule dictates that the feedback reports are distributed evenly over the uplink sub-frames. Based on the predetermined spreading rule, the base station derives which of the downlink sub-frames each feedback report refers to.

摘要： Method and apparatus for conveying feedback reports from a data receiving party (300) for data received from a data sending party (302) in a wireless connection. A plurality of feedback resources (304) assigned to different feedback information codes are allocated to the data receiving party for transmitting feedback reports. After checking whether the data was received correctly or not, the data receiving party selects a feedback resource (FR 2 ) with a feedback information code that corresponds to one or more feedback reports on the received data. The data receiving party then sends feedback information on the selected feedback resource to the data sending party, thereby conveying the corresponding feedback information code. In this way, multiple feedback reports can be conveyed in a single feedback resource to the data sending party while still retaining single carrier properties.
