Abstract:
In a communication terminal implementing a radio link control (RLC) protocol, error propagation to higher layer protocols is mitigated by use of an additional length indicator, referred to herein as a new packet indicator, in the RLC data blocks to indicate the beginning of a new higher layer packet in addition to a conventional length indicator to indicate the last segment of a higher layer packet. The new packet indicator prevents the LLC data segment at the beginning of an RLC data block from being concatenated with an LLC data segment in the previous data block even when length indicators in the previous data block are not received.
Abstract:
A method and apparatus for interrupting the lower priority packet transmission/reception for higher priority packer transmission reception within the context of a common RLC entity is provided herein. The transmission/reception of lower priority data blocks containing data segments of a first higher layer packet is interrupted to transmit/receive higher priority data blocks containing data segments of a second higher layer packet. After the transmission/reception of a final segment of the second higher layer packet, the transmission/reception of the first higher layer packet is resumed. In some embodiments, a final segment of the second higher layer packet is encapsulated in a final higher priority data block with a remaining data segment of the first higher layer packet. The final higher priority data block further includes a transition indicator to indicate a transition from the second higher layer packet back to the first higher layer packet.

Abstract:
A method (200) for a cellular system (100), with an RBS (120) which controls a cell (110) with User Equipments UE (130, 140). The RBS and the UEs exchange data which may comprise sequence numbers, and exchange reports on whether or not data has been received successfully, so that both the UE and the RBS can be the reporting party and the report receiving party. The reporting party sends a report (210) to the report receiving party on whether or not data has been received successfully, together with data to the report receiving party or to another party in the cell. The reporting party decides (220) the contents of the report using one of the following priority rules: Data with lower delay tolerance is given priority, Data detected as received in error is given priority, Data is given priority according to block sequence numbers.
Abstract:
A cellular network supports radio communication based on a first configuration which organizes a time-frequency space in first resource elements and radio communication based on a second configuration which organizes the time-frequency space in second resource elements and assigns at least one of the second resource elements to a utilization which is in conflict with the radio communication based on the first configuration. A node (100-A) of the cellular network sends an indication (20) to a communication device (10-A, 10-B). The indication (20) comprises time domain and/or frequency domain information for defining a pattern comprising at least one of the first resource elements which is to be disregarded by the communication device (10-A, 10-B) when performing radio communication with the cellular network based on the first configuration and/or the second configuration. The at least one first resource element of the pattern defines a first part of the time-frequency space which overlaps a second part of the time-frequency space defined by the at least one of the second resource elements.

Abstract:
En una terminal de comunicación que implementa un protocolo de control de enlace de radio (RLC), la propagación de error a protocolos de capa superior se mitiga por el uso de un indicador de longitud adicional, denominado en la presente como un nuevo indicador de paquetes, en los bloques de datos de RLC para indicar el inicio de un nuevo paquete de capa superior además de un indicador de longitud convencional para indicar el último segmento de un paquete de capa superior. El nuevo indicador de paquetes evita el segmento de datos de LLC al inicio de un bloque de datos de RLC de ser concatenado con un segmento de datos de LLC en el bloque de datos previo aún cuando los indicadores de longitud en el bloque de datos previos no se recibe.
