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： 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： The invention discloses a method (800) for use in a cellular wireless system (100) with a base station (120), a cell (110) in the system and a first user terminal (130) which can be scheduled for receiving traffic from the base station during a down link period, and for transmitting traffic to the base station during an up link period. There is a first guard period (TUD) between the up link period and the down link period, and a second guard period (TDU) between the down link period and the up link period. The method (800) comprises measuring the interference level in the cell for part of the time between two consecutive down link periods, and varying at least one of the following in accordance with the measured interference level: the duration of the first or second guard period, the duration of the up link period, or the traffic sent in the up link period.

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 (FR2) 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.

摘要： A communication unit acts as a data receiving party and employs a time division duplex, TDD, or half duplex frequency division duplex, FDD, arrangement when communicating with a data sending party. A method of transmitting feedback reports for data blocks received in receive, RX, sub-frames to indicate whether errors have occurred in the data blocks comprises: obtaining allocation parameters for the connection indicating that the number of required feedback reports is greater than the number of allowed feedback reports during a given sub-frame sequence, and scheduling a compressed feedback report that refers to a set of data blocks in plural received RX sub-frames.

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： Embodiments herein relates to a method in a radio base station (12) for handling a timing of uplink transmission from a user equipment (10) to the radio base station (12) in a radio communications network. The user equipment (10) is served in a cell (14) controlled by the radio base station (12), and which radio base station (12) and user equipment (10) are comprised in the radio communications network. The communications in the cell (14) are organized in radio frames comprising subframes. The radio base station (12) receives a first uplink transmission from the user equipment (10) in a subframe related to the radio base station (12). The radio base station then estimates a time parameter value based on a distance between the user equipment (10) and the radio base station (12) when the first uplink transmission is transmitted from the user equipment (10). The radio base station (12) then sets a time value (NTA1) in a message, which time value (NTA1) is to be used to set a timing of a second uplink transmission at the user equipment (10). The time value (NTA1) is based on the estimated time parameter value and a time offset value (DeltaT). The radio base station (12) then transmits the message comprising the time value (NTA1) to the user equipment.
