摘要： According to an aspect, a wireless device is configured to report, to a base station, channel quality information (CQI) using a predetermined set of CQI index values, where each CQI index value is interpreted by the wireless device and the base station as corresponding to a combination of modulation and coding rate. The wireless device determines, based on a downlink signal configuration, that a first one of the CQI index values corresponds to no modulation and coding rate that can be used for transmissions to the wireless device from the base station. The wireless device transmits the first CQI index value to the base station to signal information other than a combination of modulation and coding rate. The base station receives the first CQI index value and interprets it to signal information other than a combination of modulating and coding rate.

摘要： In one aspect, a wireless device receives a first data transmission from a base station during a predetermined subframe interval and within a duration that is less than a maximum data transmission duration that is possible within the predetermined subframe interval, and determines a transmission time for transmitting HARQ feedback to the base station such that the determined transmission time depends on which subset of symbols within the predetermined subframe interval was used for the first data transmission. The wireless device transmits HARQ feedback for the first data transmission at the determined transmission time. In another aspect, a base station transmits the first data transmission and determines a reception time for receiving HARQ feedback such that the determined transmission time depends on which subset of symbols within the predetermined subframe interval was used. The base station receives HARQ feedback for the first data transmission at the determined transmission time.

摘要： Embodiments herein relate to a method in a user equipment (10) for transmitting uplink control information in time slots in a subframe over a radio channel to a radio base station. The radio channel is arranged to carry uplink control information and the user equipment and radio base station are comprised in a radio communications network. The uplink control information is comprised in a block of bits. The user equipment maps the block of bits to a sequence of complex valued modulation symbols. The user equipment also block spreads the sequence of complex valued modulation symbols across Discrete Fourier Transform Spread - Orthogonal Frequency Division Multiplexing (DFTS-OFDM) symbols. This is performed by applying a spreading sequence to the sequence of complex valued modulation symbols, to achieve a block spread sequence of complex valued modulation symbols. The user equipment further transforms the block-spread sequence of complex valued modulation symbols per DFTS-OFDM symbol. This is performed by applying a matrix that depends on a DFTS- OFDM symbol index and/or slot index to the block-spread sequence of complex valued modulation symbols. The user equipment also transmits the block spread sequence of complex valued modulation symbols that has been transformed over the radio channel to the radio base station.

摘要： A method (700) for use in a cellular system (200) comprising a plurality of base stations (112, 122, 132, 142) for the control of the traffic to and from a cell (110, 120, 130, 140), in which system (200) the communication between users in a cell and their base station is divided into an up link period (UL), and a down link period (DL), with guard periods between uplink and downlink periods. Each base station utilizes time information from one of a number of synchronization sources in order to time the down link, up link and guard periods properly. The method comprises letting each of the base stations use information on the inaccuracy of the synchronization source of the base station in order to adapt its downlink periods so that they do not interfere with up link periods in one or more of the other base stations in said plurality.
