摘要： A first wireless communication device (14-1) belongs to a first (12-1) of multiple groups (12) of wireless communication devices (14). Devices (14) in any given group (12) are synchronized to the same timing reference and devices (14) in different groups (12) are not synchronized to the same timing reference. The first device (14-1) receives a message that indicates, for each of one or more of the groups (12), a range of possible values for misalignment between the timing reference of that group (12) and a common timing reference. The range accounts for uncertainty in that misalignment. The first device (14-1) determines, based on the one or more ranges, intervals of times during which direct control signaling is expected to be received at the first device (14-1) from one or more devices (14) in one or more other groups (12-2, 12-3). The first device (14-1) then adjusts intervals of times during which it is configured to operate in an awake state to narrowly encompass the intervals of times during which the direct control signaling is expected to be received.

摘要： The invention relates to a method for controlling a bit-rate of a session in a packet-switched communications system where multiple sessions are set-up via a shared resource. A current bit-rate of the session is compared to a bit-rate range valid for the session to determine a distance from the position of the current bit-rate to one of the end-points of the bit-rate range. The current bit-rate is then adapted differently depending on the distance to the selected end-point. By controlling the bit-rate of each session that is set-up via the shared resource for applications that provide delay-sensitive services to users in this way the method and corresponding system and sender-receiver arrangements have the effect that rate adaptations can be distributed among the applications so that users share responsibility for rate adaptations.

摘要： The present disclosure relates to transmitting assistance information from a first node to a second node. In one embodiment, a first node includes a wireless transmitter and a wireless receiver. In response to transmitting a preference indicator for a first configuration to a second node via the wireless transmitter or receiving a reconfiguration request associated with the preference indicator for the first configuration, the first node starts a timer set to a value that defines an amount of time before the first node is permitted to transmit a preference indicator for a second configuration to the second node. The first node then blocks transmission of the preference indicator for the second configuration to the second node until the timer has expired. In this manner, excessive signaling of preference indicators from the first node to the second node is avoided.

Furthermore, the wireless device (120) sends, to the radio network node (110), a second message, which indicates to the radio network node (110) that the first set of resources is available for use by the radio network node (110) when the radio network node (110) allocates resources for cellular transmissions associated with the wireless device (120).

摘要： The UE, source eNodeB, and/or target eNodeB use one or more existing Radio Resource Control (RRC) messages already available during handover to exchange at least one status report comprising UE assistance information, such as power preference indicators (PPI). The UE and the target eNodeB are thus able to obtain the same up-to-date UE status without any additional signaling. In one embodiment, the UE exchanges a handover preparation status report with the target eNodeB using a first RRC reconfiguration message transmitted from the source eNodeB to the UE, where the handover preparation status report is generated during handover preparation by the target eNodeB. In another embodiment, the UE exchanges a handover execution status report with the target eNodeB during handover execution using a second RRC reconfiguration message transmitted from the UE to the target eNodeB, where the handover execution status report is generated during handover execution. In another embodiment, the UE exchanges multiple status reports with the target eNodeB using multiple RRC reconfiguration messages, where the status reports are generated during handover preparation and handover execution. The handover preparation status report is transmitted from the target eNodeB to the UE and includes the status report as perceived by the target node at the time of handover preparation. The handover execution status report is transmitted from the UE to the target eNodeB and includes the status report as stored in the UE memory at the time of handover execution. The first RRC reconfiguration message is a RRC connection reconfiguration message and the second RRC reconfiguration message is a RRC connection reconfiguration complete message.
