Abstract: Methods for signaling information to a group of users in a communication network supporting a broadcast-multicast service are described, in which one or more indicator bits of a sequence may be assigned to indicate transmission of signaling information that is related to the group. The sequence may be transmitted to the group on a first channel, with the signaling information related to the group being transmitted on a second channel.

Abstract: A method of triggering registration of a mobile station in a network supporting broadcast multicast services employs registration triggers based on flow conditions and frequency conditions. For example, a registration message may be generated based on a change in frequency, from a first frequency to a second frequency, that is monitored by the mobile station. If the second frequency is not known to the network based on flow identifier information previously registered by the mobile station with the network, a registration to the network is triggered. By sending a registration, the network may page a mobile station on a single, given frequency, since the registration message indicates the mobile station's presence on that given frequency.

Abstract: A scheduler and a method for scheduling transmissions to a plurality of users (105) in a communication network assigns a higher target minimum throughput for receiving a next transmission to a user based on a quality of service (QoS) class of the user. A token count that tracks the user's achieved performance relative to a target minimum throughput Is determined for each user in given timeslot, and a weight is determined for each user based on one or more of the token count and a current rate requested by the user. A user having the highest weight as determined by a weight function is scheduled to be served the next transmission. User priority for scheduling may be downgraded if an average data rate requested by the user is less than the target minimum throughput.

Abstract: In an embodiment, a composite signaling message part is formed to include at least two segments (500), each segment (500) including data identifying a different user equipment (UE). In another embodiment, a different portion of a composite signaling message part is transmitted over at least one same time slot in each of the shared control channels; the part including at least two segments (510, 530) and each segment (510, 530) including data identifying a different user equipment (UE). In these embodiments, the part further includes a cyclic redundancy code (550), (CRC) generated by jointly encoding the at least two segments (510, 530). In a further aspect of the method, more than one shared control channel jointly carrying a signaling message are power controlled such that each shared control channel carrying more data associated with one of the UEs is power controlled in accordance with that UE. In a still further embodiment, the channelized code information for a dedicated control channel is divided between first and second parts of the shared control signals.

Abstract: Un procedimiento para controlar la energía de transmisión de una pluralidad de canales de control compartidos que transportan conjuntamente un mensaje de señalización, incluyendo el mensaje de señalización datos para una pluralidad de equipos de usuario (UE), caracterizado por: asignar una porción del mensaje de señalización a cada uno de la pluralidad de canales de control compartidos, de modo que cada canal de control compartido transporte más datos adicionales asociados con uno en particular de la pluralidad de UE en comparación con los datos del resto de UE; y controlar la energía de transmisión para cada canal de control compartido basado en los datos adicionales del UE concreto asociado.

Abstract: Disclosed is a method of sub-packet adaptation based on data rate. Specifically, the size of a sub-packet is adapted to a data rate at which the sub-packet is to be transmitted. In one embodiment, the sub-packet is size adapted to the data rate in a format that would allow such size adapted sub-packet to be soft combined with another sub-packet of a same or different size. The size adapted sub-packet may be transmitted prior to or after the other sub-packet.
