Abstract: Methods and apparatus for improving the reporting of mobility information are disclosed. An example method, suitable for implementation in a mobile terminal such as an LTE UE, begins with the detecting of a transition from idle state to connected state. The mobile terminal subsequently transmits mobility information to the network in response to or in connection with the transition. The mobility information sent to the network includes one or more of several information elements or information types, including a list of recently visited cells, including information specifying a time-of-stay in each cell, or timestamp information that can be used to derive the mobile terminal's time in each cell. GPS-based speed information or other generic speed information may be included. Complementary methods for implementation in a base station and corresponding apparatus are also disclosed.

Abstract: The present invention relates to a method in a cellular communication system, for avoiding errors in a HARQ process, wherein an NDI flag is used both for indicating either semi-persistent scheduling, SPS activation or SPS retransmissions, and also for indicating, by toggling of the flag, a new transmission in dynamic scheduling mode. The method comprises the steps of receiving, in a scheduling message, an indication that dynamically scheduled transmission will take place; if a semi persistent resource has occurred for the same HARQ process since a previously received indication for dynamically scheduled transmission, then considering the NDI flag to be toggled regardless of the value of the NDI flag. Thus, if the condition is fulfilled, a UE will always regard the NDI flag as indicating or requesting a new data transmission.

Abstract: Power headroom reports may be transmitted from a wireless terminal to a base station wherein a primary component carrier and at least one secondary component carrier are provided for uplink transmissions from the wireless terminal to the base station and wherein a respective component carrier index is assigned to each of the at least one secondary component carriers provided for the wireless terminal. Respective power headroom reports may be generated for the primary component carrier and for each of the at least one secondary component carriers, and a MAC control element may be generated including the power headroom reports for the primary and secondary component carriers. More particularly, the power headroom reports for each of the at least one secondary component carriers may be arranged in order of the component carrier indices for the respective secondary component carriers.

Abstract: A radio communications link is established between radio stations, and a semi-persistent radio resource is allocated to support data transmission over the communications link. The semi-persistent radio resource is associated with a corresponding automatic repeat request (ARQ) process identifier. Non-limiting examples of a semi-persistent radio resource include a regularly scheduled transmission time interval, frame, subframe, or time slot during which to transmit a data unit over the radio interface. Retransmission is requested of a data unit transmitted using the semi-persistent radio resource. The ARQ process identifier associated with the semi-persistent resource is used to match a retransmission of a data unit dynamically scheduled on the communications link with the requested data unit retransmission. In a preferred example embodiment, the ARQ process identifier is a hybrid ARQ (HARQ) process, where a retransmitted data unit is combined with a previously-received version of the data unit.

Abstract: The present invention relates to a transmission of information in a wireless communication network between a radio access node and a relay node, wherein, according to a new ground rule, for each allocated downlink subframe for a downlink transmission from the access node to the relay node, an uplink transmission subframe for an uplink transmission is allocated four transmission time intervals later. A downlink subframe is only allocated when a further subframe of the same transmission time interval for a transmission from the relay node to the user equipment is a subframe of a type that indicates to a user equipment that no data are received beyond a control region of the subframe.

Abstract: A node (100; 300) of a mobile network is responsible for scheduling transmissions of data blocks between the mobile network and a terminal device (200, 200?). The node (100; 300) may for example be a base station (100) or a control node (300) of the mobile network. The node (100; 300) determines a processing time required by the terminal device (200; 200?) for processing signals for transmission of one of the data blocks. The processing time is determined from a plurality of supported processing times. On the basis of the determined processing time, the node (100; 300) schedules the transmission of the data block. The terminal device (200, 200?) may provide control data for determining the processing time to the node (100; 300).

Abstract: A method is provided in a receiving node for handling status information of data units transmitted from a sending node to the receiving node over a radio link. The receiving node establishes (401) that a number of data units that has been transmitted by the sending node are missing. The receiving node sends (402) a reduced status message to the sending node over the radio link, which message is reduced such that it comprises the negative acknowledgement for a first part of missing data units and omits negative acknowledgements for the rest of the missing data units. The omitted negative acknowledgement for the rest of the missing data units will not erroneously be interpreted as correctly received data units by the sending node.

The base station derives, from the received information element, MBMS reception capabilities of the terminal. The base station determines a number of carriers, which are configurable by the base station as serving cell of the terminal, such that the terminal is enabled to receive at least one MBMS.

Abstract: A mobile station in a Long Term Evolution (LTE) communication network transmits Packet Data Convergence Protocol (PDCP) protocol data units to a base station and the base station transfers corresponding PDCP service data units to a core network. The mobile station is configured to support handover from a source base station to a target base station. The mobile station generates new PDCP protocol data units for missing PDCP service data units, and transmits the new PDCP protocol data units to the target base station, responsive to signaling from the target base station that indicates which PDCP service data units have been successfully received at the target base station. The new PDCP protocol data units are generated using ciphering specific to the connection with the target base station, from corresponding PDCP service data units buffered at the mobile station.

Abstract: 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.

Abstract: A method aims at controlling parameters used by communication terminals of a telecommunication system which enables discontinuous reception. The discontinuous reception involves DRX cycles during each one of which a communication terminal wakes up at least once to monitor a downlink control channel. The telecommunication system enables the use of DRX cycles of different lengths. The method includes a determining procedure (s10) comprising determining, on a per communication terminal basis, whether the communication terminal is eligible to rely on a terminal-controlled mobility procedure, wherein determining is based on at least one characteristic of the communication terminal. The method also includes a setting procedure (s20) comprising, at least for one of the possible outcomes of the determining procedure (s10), setting one or more parameters on the communication terminal accordingly.

Abstract: In a wireless communication network where base stations receive protocol data units (PDUs) from mobile stations for decompression and deciphering for ordered, sequential transfer as service data units (SDUs) to an associated core network, the teachings presented herein provide a method of supporting seamless handover of a mobile station from a source base station to a target base station. By way of example, the teachings herein apply to a network based on the E-UTRA specifications, as promulgated by the 3GPP. However, that example is non-limiting, as the teachings herein apply to any network that employs in-sequence data delivery and duplicate data detection at handover. Broadly, the source base station forwards out-of-sequence SDUs and corresponding sequence number information to the target base station in support of seamless handover, and the target base station uses that information to request retransmissions as needed for packet reordering.

Abstract: For the purpose of selecting a base station (110, 120) to be used as a serving base station of a mobile terminal (100), a traffic characteristic of the mobile terminal (100) is determined. The traffic characteristic may in particular be indicative of an asymmetry between downlink and uplink data traffic of the mobile terminal (100). On the basis of the traffic characteristic, a selection between a first mode and a second mode is performed. In the first mode the base station (110, 120) to be used as the serving base station is selected on the basis of its downlink radio capacity as compared to one or more other base stations (110, 120). In the second mode the base station (110, 120) to be used as the serving base station is selected on the basis of its uplink radio capacity as compared to one or more other base stations (110, 120).
