Abstract: A method in a base station for adapting link adaptation of a transmission between a user equipment and the base station is provided. The link adaptation relates to an initial value of a Block Error Rate, BLER, related to the transmission. The base station decides that the user equipment is in congestion responsive to a scheduling bit rate for the transmission in relation to a rate of data packets arriving to or being sent by the user equipment being below a first threshold. Responsive to the user equipment being in congestion, the base station adapts the link adaptation by increasing the value of the BLER of the link adaptation in relation to the initial value, until the user equipment is out of congestion or until the base station detects that any one of the user equipment and the base station tries to send high priority data.

Abstract: A system and method for implementing fallback on a wireless device for circuit switched fallback from a first network that does not provide a circuit switched domain service is presented. A paging message is received from the first network. The paging message instructs the wireless device to implement circuit switched fallback to a circuit switched network.

A request message for initiating the establishment of a radio connection is transmitted. The request message identifies the suitable channel type, and the service is used on the circuit switched network.

Abstract: Systems, methods, and user equipment can involve transmitting Acknowledgement/Negative Acknowledgement (ACK/NACK) bits for carrier aggregation between a first cell and a second cell in a User Equipment (UE). With the UE, for a sub-frame, a first number of ACK/NACK bits for the first cell can be compared with a second number of ACK/NACK bits for the second cell. If a first number of ACK/NACK bits for the first cell is less than a second number of ACK/NACK bits for the second cell, an ACK/NACK bit position from the first cell can be used to transmit an ACK/NACK bit for the second cell. In some implementations, one or more DTX bits can be used to set the number of ACK/NACK bits in the first cell equal to the number of ACK/NACK bits in the second cell.

Abstract: A service instance in a BEB device is allocated B-VLANs. Each of the B-VLANs may be mapped to a different ECT algorithm. For each B-VLAN of the service instance, BEB device calculates a forwarding path between the BEB device and a remote BEB device to obtain different forwarding paths for different B-VLANs of the service instance. The BEB device forwards a data flow in a first forwarding path of the service instance, and switches the data flow from the first forwarding path to a second forwarding path of the service instance if a link failure is detected in the first forwarding path.

Abstract: Physical layer characteristics, e.g., reference signal density, reference signal distribution, data parameters, etc., are defined in the physical layer for sub-frames of a transmission time interval (TTI) allocated to data packet(s) based on the number of allocated sub-frames. The flexibility provided by the solution presented herein enables the associated wireless system to better define those physical layer characteristics necessary to meet signal quality and system requirements without unnecessarily overburdening the system overhead. Thus, the reference signal overhead may be reduced, which leads to reduced system overhead and/or increased spectrum efficiency.

Abstract: Combinational networks provide simultaneous connectivity via networks of different network type between user equipment. For communication sessions on different network types, belonging to the same user equipment, a correlation check is enabled by introduction of an identifier denoted as Combinational Call Indicator (CCI). This CCI identifier in combination with the known Calling Line Identity (CLI) identifier enables user equipment and other and network entities to perform a correlation check between ongoing, or to be established, CScalls and PS-sessions. A user equipment, setting up a related communication session, sets the CCI identifier and provides the CCI identifier during the communication session setup towards the receiving user equipment or network entity, which is enabled to check whether the last received communication session is correlated to the earlier established session due to the presence of the CCI identifier.

Abstract: Group-based emergency notifications and acknowledgments are managed via a radio controller. A request to transmit an emergency notification with acknowledgment to an identified target group of subscriber devices is received at the radio controller from a requesting device. The radio controller identifies one or more base stations actively serving subscriber devices associated with the identified target group and identifies, for each of the identified one or more base stations, active channels including one or more of a control channel associated with the base station and active voice or data channels associated with the base station. The radio controller causes an emergency notification outbound signaling packet (OSP), requesting individual acknowledgment and identifying the target group of subscriber devices, to be broadcast on the identified active channels at the identified one or more base stations. Acknowledgments are forwarded back to one of the requesting device and a dispatch console.
