Method and apparatus for seamless handover in a wireless communication network

Номер: US0009426710B2

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.

A method in a User Equipment (UE) in communication with an Evolved Node B (eNB) , the method comprising:sending an In-Device Coexistence (IDC) indication to the eNB, including information of problematic uplink carrier aggregation combinations.2. The method according to claim 1 , wherein the UE only indicates an uplink carrier aggregation combination as problematic if the uplink carrier aggregation combination is a combination of uplink carriers supported by the UE claim 1 , measurement objects are configured for all corresponding downlink carriers claim 1 , and the UE experiences or expects to experience IDC problems due to the uplink carrier aggregation combination.3. The method according to claim 2 , wherein the problematic uplink carrier aggregation combination is an uplink carrier aggregation combination for which the UE experiences IDC problems.4. The method according to claim 1 , wherein a problematic uplink carrier aggregation combination is identified by a set of measurement object identities for all of the corresponding downlink carriers for the uplink carrier aggregation combination.5. The method according to claim 1 , wherein the IDC indication comprises claim 1 , for each problematic uplink carrier aggregation combination claim 1 , a set of measurement object identities for all of the corresponding downlink carriers for the problematic uplink carrier aggregation combination.6. A User Equipment (UE) for communication with ...

Принадлежит: Telefonaktiebolaget LM Ericsson AB

An apparatus, system and method for encoding system information from multiple cells and beams in a communication system. In one embodiment, the apparatus is operable in a communication system including a first beam and a second beam, and is configured to construct a system information block for the first beam. The system information block includes a common field having common system information associated with the first beam and the second beam, and a first beam specific field having first beam specific system information indexed to the first beam. The apparatus is also configured to transmit the system information block to a user equipment for access to the communication system.

Dynamic change of measurement gaps

Номер: US20200288337A1
Принадлежит: Telefonaktiebolaget LM Ericsson AB

The invention refers to a method in a user equipment, UE, for a measurement gap pattern configuration including receiving a configuration information indicative of a measurement gap pattern configuration, and a bandwidth part, BW, configuration, determining an association between measurement gap patterns and BW parts, receiving a message to change the active BW part to one of the configured BW parts, and changing the measurement gap pattern as a function of the corresponding BW part and the association; the invention further refers to a corresponding method in a network node; to corresponding UE, a corresponding network node, and computer programs.
