摘要： The present disclosure relates to a method and user equipment, UE, in a wireless communication network of performing power scaling on uplink transmission to a receiving radio access node, RAN. In particular, the disclosure relates to a method and user equipment for power scaling on uplink transmissions on a multi-radio access bearer, multi-RAB, wherein a Dedicated Physical Data Channel, DPDCH, and enhanced Data Channels, E-DCHs are configured for uplink transmission from the UE to the receiving RAN. The method comprises determining a total UE transmit power exceeding a predetermined maximum power limit value. The total UE transmit power is reduced to the predetermined maximum power limit value by reducing one or more E-DPDCH gain factors by an equal scaling factor. When a predetermined minimum E-DPDCH gain factor, ‘smallest quantised βed,k value’, is reached for all E-DPDCH gain factors βed,k, and DTX is applied for all E-DPDCHs, the method comprises applying DTX on E-DPCCH.

摘要： To facilitate, e.g., determination of access rights in a shared network context, a telecommunications network transmits, in a broadcast channel over an air interface, an access group eligibility message (300-2) to a user equipment unit (30). The access group eligibility message enables the user equipment unit to ascertain, on a basis of access group to which the user equipment unit belongs, whether the user equipment unit is eligible to operate in a cell for which the access group eligibility message is transmitted. The telecommunications network also includes a core network node (18, 20) which, upon receipt of request for/from the user equipment unit, classifies the user equipment unit in at least one of plural access groups. Further, the core network node generates, for transmission to the user equipment unit through the radio access network, an access group classification message (300-1) which advises the user equipment unit as to which of the plural access groups the user equipment unit belongs. Upon receipt of the access group classification message, the user equipment unit stores an access group classification obtained from the access group classification message in a memory (102) at the user equipment unit. In illustrated embodiments, the access group classification message can, as appropriate, be one of a location update response and a location update reject message, either of which can include the access group classification. In accordance with one aspect of the present invention, an access controller (100) of the user equipment unit (upon receiving the access group eligibility message) compares the stored access group classification with contents of the access group eligibility message to determine whether the user equipment unit is allowed access to the cell for which the access group eligibility message is transmitted. This determination thus allows the user equipment unit to make a decision whether or not it has access rights in a particular cell, and thereby addresses access rights in complex network configurations such as a shared network situation. Further, the present invention provides an access rights determination scheme generally applicable to a user equipment unit regardless of whether it is in the IDLE mode or in one of the following states of the CONNECTED mode: CELL FACH state; CELL PCH state; and URA PCH state.

摘要： A system and method for improving soft hand-off in a CDMA system uses mobile station location and velocity information to maintain soft hand-off legs with those cells in which the mobile station is more likely to be located. The system and method of the present invention estimates the weighted probability of the mobile station arriving in neighboring cells and produces 'bias' values for those cells that the mobile station is more likely to be entering or to be located in. These bias values are used for modifying signal quality values for those cells, and for determinig whether the current cell or neighbor cells are to be placed in an active set so as to establish, or maintain, soft hand-off legs. The system and method of the present invention thus chooses those cells which are more likely to be retained as soft hand-off legs and therefore reduces the overall number of soft hand-offs.

摘要： The disclosure relates to a method performed by a communication device 3 for uplink transmission. The communication device 3 is configured with a primary carrier for uplink data transmission and a dedicated secondary carrier for uplink data transmission to a network node 5A, 5B, 7. The method comprises: transmitting 604 a scheduling information report using the primary carrier; receiving 608 a grant to use the dedicated secondary carrier; and transmitting 610 user data using a data channel on the dedicated secondary carrier upon reception of the grant for the dedicated secondary carrier, wherein the communication device 3 is configured such that it does not transmit any data on the dedicated secondary carrier unless receiving a grant for the dedicated secondary carrier. The disclosure also relates to corresponding method in network node, and to a communication device and network node.
