摘要： A wireless system has a high rate data channel for time multiplexed communications to multiple mobile stations (MSs). Control channels include a forward link common power control channel and reverse link feedback channels for pilot, forward channel quality, and data acknowledgements from each MS. An MS can have an active state for data communications, for which these control channels are used at the full (time slot) rate, or a control hold state, in which acknowledgements are not needed and the others of these control channels can be shared among a plurality of MSs in the control hold state and each using a reduced rate such as ½, ¼, or ⅛ of the full rate. The arrangement can support an increased number of active MSs, facilitating an increased total throughput on the high rate data channel, without increasing system resources for the control channels.

摘要： In some embodiments of the invention, OFDM symbols are transmitted as a plurality of clusters. A cluster includes a plurality of OFDM sub-carriers in frequency, over a plurality of OFDM symbol durations in time. Each cluster includes data as well as pilot information as a reference signal for channel estimation. In some embodiments, a plurality of clusters collectively occupy the available sub-carrier set in the frequency domain that is used for transmission. In some embodiments of the invention data and/or pilots are spread within each cluster using code division multiplexing (CDM). In some embodiments pilots and data are separated by distributing data on a particular number of the plurality of OFDM symbol durations and pilots on a remainder of the OFDM symbol durations. CDM spreading can be performed in time and/or frequency directions.

摘要： A mobile terminal in a wireless communication network may be one of several modes of operation. When in an idle mode, the mobile terminal may avoid a lengthy random access procedure normally associated with responding to a page from a base station, if the base station includes in the page an indication of a resource that the mobile terminal may utilize when responding to the page. Additionally, the mobile terminal may transmit an efficient location update MAC header to a base station, whether prompted to by a page from the base station or not. Furthermore, without leaving the idle mode or a sleep mode, the mobile terminal may exchange short data burst messages with a base station.

摘要： A first unit successively transmits data blocks destined for a second unit. For at least some of the transmissions of blocks, the second unit returns an acknowledgement signal indicating whether the data block transmitted has been correctly received. The first unit transmits a redundancy block with regard to a block previously transmitted for which the acknowledgement signal received indicates incorrect reception. Each block transmitted is accompanied by an identification signal indicating whether it is a redundancy block. The first unit associates each acknowledgement signal received with a block transmitted in a temporal relation determined with the reception of this acknowledgement signal. In response to the reception of an identification signal inconsistent with an acknowledgement signal previously returned, the second unit returns to the first unit a restart command signal for the transmission of the blocks.

摘要： The present invention provides for a scheduling scheme to be used with respect to a given mobile station. It is determined whether the given mobile station is or is not in soft-handoff. This is performed through examining a reduced active set. The reduced active set is based upon the active set, and the selection of the reduced active set includes considerations such as received reverse link channel signal strength. If the mobile station is in soft hand-off or with reduced active set size of greater than one, congestion control scheduling of reverse link communications from the given mobile station is utilized, using a data rate set by the congestion control of the reverse link channel. If the mobile station is not in soft-handoff or with reduced active set size of one, explicit scheduling of the reverse link communications from the given mobile station is utilized, using a data rate set by the explicit data rate control of the reverse link channel.
