A method of operating a telecommunications system (20) comprises a radio access network node (34) offering plural parameter configurations to a wireless terminal (30) over a radio interface (32) and the wireless terminal (30) choosing a preferred parameter configuration from among the plural parameter configurations offered by the radio access network node. In an example embodiment and mode, the method further comprises the radio access network node (34) offering the plural parameter configurations as a list of discontinuous reception (DRX) configuration information elements, each discontinuous reception (DRX) configuration information element comprising one parameter value for each of the one or more corresponding discontinuous reception parameters defined for the configuration information element.

Methods and arrangements in a base station are provided for scheduling radio resources to a user equipment. A time offset value is received that is associated with the moment of time when a frame of data was generated in the user equipment buffer. The moment of time when the frame of data was generated in the user equipment buffer is determined, based on the received time offset value. Thus, the buffer state of the user equipment buffer is predicted by using the determined moment of time when the frame of data was generated in the user equipment buffer. Radio resources are granted to the user equipment, based on the predicted buffer state of the user equipment buffer. Methods and arrangements in a user equipment for assisting the base station in scheduling radio resources are also provided herein.

Fields such as sequence numbers and length indicators of protocol layers are extended in extended headers so as to be backwards compatible with corresponding legacy headers. The existing fields of the legacy headers are not directly extended. Instead, existing fields are logically concatenated with other fields of the extended header. Whether the extended fields or legacy fields will be used can be determined dynamically based on current transport block size or semi-statically by higher layers.

Methods and systems present solutions to, for example, the problem of unnecessary preparedness for suspended retransmissions in the user equipment (UE) which contributes to power drain in the device battery. One method for monitoring a Physical Downlink Control Channel (PDCCH) for adaptive retransmission grants in a radio communication system includes: monitoring, by a user equipment (UE), the PDCCH for adaptive retransmission grants; receiving, by the UE, a hybrid automatic repeat request (HARQ) acknowledge (ACK) message, and ceasing, by the UE, to monitor the PDCCH for adaptive retransmission grants after receipt of the HARQ ACK message.

A radio access network comprises a donor base station node (29) and a relay base station node (20). The relay base station node (29) participates in communications across a first radio interface with a wireless terminal (30) and also participates in communications over a backhaul link across a second radio interface, the second radio interface reusing at least some functionality of the first interface. The donor base station node (28) configures a subframe configuration pattern. The subframe configuration pattern is arranged to specify which subframe(s) of a frame structure may be utilized for the backhaul link. As a result of subframe configuration, a HARQ process state in a HARQ process at one of the base station nodes is known by the other base station node by any of several operational modes.

Method and arrangement in a base station for providing feedback to user equipments in a cell concerning the reception status of data received from the user equipments. The base station and the user equipments are comprised in a wireless communication system, adapted for contention based transmissions. The method comprises sending a contention based grant to a plurality of user equipments within the cell, receiving data from any user equipment and verifying if the data is correctly received. Also, the method comprises sending feedback to any user equipment that has used the contention based grant, wherein the feedback comprises an ACK, if it is verified that data has been correctly received from at least one user equipment and the feedback comprises a NACK if it is verified that data has not been correctly received from any user equipment. Also, a corresponding method and arrangement in a user equipment is described.

The technology disclosed provides the ability for a subframe to be configured as a “flexible” subframe. As a result, at least three different types of subframes in a TDD system may be configured: a downlink (“DL”) subframe, an uplink (“UL”) subframe, and a “flexible” subframe. The use of flexible subframes is determined based on a primary TDD configuration, and in a preferred example, on the existing primary TDD configuration in the network. If there is secondary TDD configuration, flexible subframes may be determined based on both the primary and secondary configurations, e.g., using specific rules. Also, the HARQ feedback timing for downlink (DL) transmissions may be determined based on the secondary TDD configuration. Preferred examples ensure that uplink (UL) feedback does not collide with a flexible subframe used for DL transmission. The technology preferably is compatible with legacy UEs.

The present invention relates to a method for detecting loss in DRX synchronization in a telecommunications system. The present invention further relates to a base station configured to perform the method for detecting the loss in DRX synchronization. The method comprises the steps of assigning radio resources to a UE for enabling the UE to send uplink information to the base station. The method further comprises the step of detecting loss in DRX synchronization when information that is expected by the base station is absent on the assigned resource(s).
