摘要： Aspects of the present invention relate to improved systems and methods for handing over a UE from a source node to a target node. In some embodiments, the target node receives UL and DL count information directly from the UE being handed over, rather than from the source node or from a core network node.

摘要： Some of the example embodiments presented herein are directed towards a user equipment (501), and corresponding method therein, for uplink timing alignment. The user equipment (501) may initiate a timing advance value to zero during a creation of a timing advance group, a modification of a timing advance group, or if a TAC MAC CE command has not been performed. The user equipment (501) may further update the timing advance value based on a received TAC MAC CE command. Some of the example embodiments presented herein are directed towards a base station, and corresponding method therein, for uplink timing alignment. The base station (401) may be configured to estimate a proximity of the user equipment (501) to an uplink receive or an uplink cell size of the user equipment. The base station may determine a TAC MAC CE based on the estimation and send the TAC MAC CE to the user equipment (501 ) for uplink timing alignment.

摘要： A method in a network node for transmitting control information to a user equipment in a telecommunications system is provided. The control information is scheduled in time intervals of a downlink shared data channel, wherein the control information is allocated resource elements in resource blocks of a time-frequency Orthogonal Frequency Division Multiplexing, OFDM, grid in the time intervals in which the control information is scheduled. The network node determines for a time interval, a set of user equipments for which control information is scheduled in the time interval. Also, it selects for a user equipment comprised in the determined set of user equipments, at least one group of user equipments amongst one or more groups of user equipments to which the user equipment is assigned. It also prepares a group signal corresponding to the selected one group of user equipments by allocating resource elements in the resource blocks of the time interval to the group signal. Furthermore, the network node transmits the prepared group signal in the allocated resource element in the time interval to the user equipment such that the user equipment is enabled to determine whether the control information that is allocated resource elements in the time interval is intended for the user equipment or not. A network node, a method in user equipment and a user equipment are also provided.

摘要： A new uplink control channel capability is introduced to enable a mobile terminal to simultaneously report to the radio network multiple packet receipt status bits and channel-condition bits. In particular, if a mobile terminal is configured with channel selection (e.g., with PUCCH format 1b) and is configured to report or is capable of reporting periodic CSI and ACK/NACK bits together, then the mobile terminal can use one or more out of a set of preconfigured uplink control resources and transmit (1140) a PUCCH using a new format in this resource. The particular uplink control channel resource the mobile terminal uses from this set is selected (1120) based on an information field contained in a downlink control message corresponding to the ACKed or NACKed data transmission, for example, such as the Transmit Power Control (TPC) command in a downlink assignment message.

摘要： Devices and methods for transmitting information in resource blocks between a base station and one or more communication devices are disclosed. In each resource block (RB) used for a data or control channel transmission, a plurality of non-over!apping regions of resource elements (REs) are defined. Each region is associated with one or multiple unique reference symbols (RSs), and may be further associated with one or more antenna ports. When user equipment (UE) demodulates the information it receives in a particuiar region of an RB, it uses the RS and/or antenna port associated with that region. The RS and/or antenna port information may be used, for example, to estimate a channel of the communication network or to demodulate and decode the data contained within the associated regions.

摘要： The present invention relates to a base station (BS) and to a method for supporting UE positioning measurements in a wireless communication system. The method comprises transmitting (610) signals associated with a first cell, where the signals comprise positioning reference signals. The method also comprises transmitting (620) signals associated with a second cell, wherein the second cell is configured to have a lower transmission capacity than the first cell, and discontinuing (630) the transmission of at least one signal associated with the first cell except for the positioning reference signals. The energy consumption of the BS may thus be reduced while still supporting accurate positioning measurements.

摘要： A system (30) and method for determining a Physical Uplink Control Channel, PUCCH, power control parameter h(n CQI ,n HARQ ) for two Carrier Aggregated, CA, PUCCH formats— PUCCH format 3 and channel selection. The value of h(n CQI , n HARQ ) may be based on only a linear function of n HARQ for both of the CA PUCCH formats. Based on the CA PUCCH format configured for the User Equipment, UE, (12) the eNodeB (16) may instruct the UE to select or apply a specific linear function of n HARQ as a value for the power control parameter h(n CQI , n HARQ ) > 80 AS to enable the UE to more accurately establish transmit power of its PUCCH signal. Values for another PUCCH power control parameter---- Δ F_PUCCH (F) - are also provided for use with PUCCH format 3. A new offset parameter may be signaled for each PUCCH format that has transmit diversity configured.

摘要： A system (30) and method to instruct a User Equipment, UE, (32) how Uplink Control Information, UCI, on a Physical Uplink Shared Channel, PUSCH, should be transmitted with carrier aggregation. A semi-static signaling of a UCI mapping bit, via a Radio Resource Control, RRC, parameter, is used by a base station such as an eNodeB (36) to require the UE to transmit UCI using one of two pre-determined UCI transmission modes. The bit can be decided by the base station, considering, for example, the available bandwidth or quality of different Uplink Component Carriers, UL CCs, associated with the UE. This network-based solution allows the network to either configure a general rule of UCI transmission by the UE or to enforce the UCI transmission on the Uplink Primary cell, UL Pcell.
