摘要： The present invention provides a muting configuration for reference signal (RS) transmission as a pattern defined by at least the combination of a muting sequence and a reference point. Muting occasions for a given wireless communication network cell (20) thus are differentiated from another cell by use of a different muting sequence, a different reference point, or both. Moreover, in one or more embodiments, the present invention provides for the use of a common muting sequence or reference point across cells (20), with muting occasions being differentiated between cells (20) through use of different reference points (in the case of a common muting sequence), or through use of different muting sequences (in the case of a common reference point), or different sequences and different reference points. Such arrangements simplify the signaling needed to control or indicate the muting configuration in use in the cells of interest, provide an advantageous basis for propagating muting configurations among cells (20), eliminate the need for predefined muting configurations, and the need for blind detection of muting by wireless communication apparatuses (14), such as UEs.

摘要： According to several disclosed techniques, a wireless network provides assistance information to a mobile terminal for cell selection at re-establishment of a connection after a radio link failure. An example method is implemented in a mobile terminal served in a first cell of a wireless network, and includes receiving (510) a configuration message from the network, the configuration message identifying at least one carrier frequency. Upon subsequently losing connection with the first cell without receiving a handover command, the mobile terminal initiates (520) a cell search using the identified at least one carrier frequency, based on the configuration message.

摘要： Methods and arrangements in a base station and a User Equipment are provided. The methods and arrangements relates to the scenario when the UE is handed over from a source base station to a target base station in a handover scenario, and wherein the target base station may not support functionalities which the source base station and the UE support. The method in the UE comprises receiving (501) a configuration message from the target base station via the source base station, configuring (502) the UE based on the received configuration message from the target base station by searching (503) for a second field in an information element of the received configuration message. The presence/non-presence or a value of the second field is indicative of how to manage a configured first functionality associated with an optional first field, wherein the configured first functionality may not be supported by the target base station.
