摘要:
A method including receiving data in at least one link layer message from a first access node at a second access node, the first access node being associated with the second node; determining if said data is to be sent to a third access node; and, sending the data in at least one internet protocol message to the third access node. The first access node may be a relay node.

Format of a downlink control channel for a user equipment UE is changed in conjunction with switching the UE between being enabled for cross carrier scheduling and being disabled for cross carrier scheduling. The changed format is used on at least one serving cell of the UE's configured set of component carriers CCs. In one embodiment the changed format comprises an explicit carrier indicator field CIF for the case in which the switching is from disabled to enabled; and the changed format has no explicit CIF when the switching is from enabled to disabled. In another embodiment switching from disabled to enabled comprises the UE's configured set of CCs being changed from one to multiple cells; and switching from enabled to disabled comprises the UE's configured set of CCs being changed from multiple cells to one cell. In one embodiment the changed format is implicit.

A method includes transmitting a paging indicator indicating to user equipment assigned to one or more groups that the user equipment are to attempt to receive paging messages including paging information targeted to at least one of the one or more groups; and transmitting in a channel the paging information in the paging messages. Another method includes receiving a paging indicator indicating a user equipment is to attempt to receive paging messages including paging information targeted to at least one of one or more groups; and receiving from a channel the paging information in the paging messages. A method includes sending a request message to user equipment assigned to one or more groups, the request message comprising an indication to cause the user equipment to read device trigger information in a system broadcast message; and sending the device trigger information in the system broadcast message.

Aspects of the present invention relate to methods and entities involved in enabling and improving inter-domain handover. A PS based RAN such as eUTRAN can identify which potential handover to prepare and which handover to initiate, PS-PS or SR-VCC based on: (1) the UE's SR-VCC capabilities, (2) “SR-VCC indication” from the MME, (3) active VoIP bearer, and (4) target cell capabilities.

A network access node eNB sends to a user equipment UE a pattern of subframe measurement restrictions and an indication of how to utilize the pattern for measuring subframes. The indication may select from among: the UE's own-cell measurements; the UE's neighbor-cell measurements; both same and neighbor-cell measurements, and no measurement restrictions. The eNB may generate the pattern from an almost-blank subframe ABS pattern for the UE's own-cell and of its neighbor-cell. The pattern and indication may be sent in separate RRC messages, or if sent in one message there is a second indication sent in a second RRC message instructing the UE to terminate utilizing the pattern and indication for restricting its subframe measurements. Embodiments are particularly useful for inter-cell interference mitigation eICIC for the LTE-Advanced system.
摘要:
The invention relates to methods for providing a network element of a communications network with data, in particular HSDPA related data. In order to enable the transmission of user data, it is proposed that a controller of the network uses a dedicated frame structure for assembling frames with said user data. The frames can then be transmitted from the controller via an interface to the network element. In order to enable the transmission of control parameters, it is further proposed that an interface application protocol is employed which allows the controller to add control parameters to control messages transmitted from the controller to a network element via the interface.

A channel inverse multiplexer/multiplexer (IMUX/MUX) (14a) of a MAC sublayer (14) of a UTRAN RNC (11) for providing to a UE (18) traffic (communication signals including in general both control and user data) at a higher rate than the UE can accept over a single channel. The channel IMUX/MUX performs inverse multiplexing of traffic for downlink, and multiplexing of traffic on uplink, and does so in a way that is transparent to all other layers/entities of the UTRAN (11 17) and to the UE (18).
摘要:
GERAN Cell Capability indicated in a bit of an Information Element is modified to indicate whether a neighbor GERAN cell belonging to a radio access technology (GSM) supports packet switched (PS) handover or not so that the serving radio network controller can be in possession of such information before deciding whether to attempt PS handover to the cell of the GSM network and thereby avoid unnecessary signaling in case such a handover is not possible and to thereby allow the serving radio network controller to consider some other target cell or some other solution than triggering PS handover toward that GSM cell.
摘要:
In an exemplary aspect of the invention there is a method comprising receiving cell-related information from a first access node at a second access node, and using the cell-related information during at least one of a handover and a radio resource control (RRC) related operation. Where the use of the exemplary embodiments of this invention include, but are not limited to, reducing handover execution time, reducing the signaling load related to an unsuccessful handover and/or radio resource control related procedures, and reducing the need of a user equipment to measure unnecessary cells.
