Abstract: A method and apparatus manages resources in a wireless communication system by transmitting a multi-carrier switch command message to an access terminal instructing the access terminal to switch between a diversity mode where each antenna module of a plurality antenna modules receives a single carrier signal transmitted at a single carrier frequency and a multi-carrier mode where a first antenna module of the plurality antenna modules receives a first multi-carrier signal transmitted at a first carrier frequency and a second antenna module receives a second multi-carrier signals transmitted at a second carrier frequency.

Abstract: A method and apparatus resolves conflicts and ambiguities of GSM standards arising in DTM by monitoring only selected downlink timeslots for uplink status flags (USFs). Downlink timeslots with a packet data channel (PDCH) are monitored for a USF from a lowest numbered time slot, B(0), to a maximum time slot B(MAX) where B(MAX) is equal to the lowest transmission uplink timeslot, B(x), in the corresponding TDMA uplink frame if the second lowest transmission uplink timeslot B(x)+1, is a circuit switched timeslot and where B(MAX) is equal to the second lowest transmission timeslot in the corresponding TDMA frame, B(x)+1, otherwise.

Abstract: A base station is provided, which includes a transmitter configured to transmit a multi-carrier switch command message to an access terminal instructing the access terminal to switch between a diversity mode where each antenna module of a number of antenna modules receives a single carrier signal transmitted at a single carrier frequency and a multi-carrier mode where a first antenna module of the number of antenna modules receives a first multi-carrier signal transmitted at a first carrier frequency and a second antenna module receives a second multi-carrier signal transmitted at a second carrier frequency. The multi-carrier switch command message is in the format of a modified Packet Downlink Assignment message in accordance with a Global System for Mobile Communication (GSM) Enhanced Data for Global Evolution (EDGE) Radio Access Network (GERAN) standard protocol. The message includes a multi-carrier switch indicator instructing the access terminal to switch to the multi-carrier mode, and a multi-carrier channel indicator assigning channels to the access terminal. The corresponding method and access terminal are also provided.

Abstract: A base station (110) in a wireless communications network (100) counts mobile stations (114) receiving broadcast content via multi-user channel. The base station broadcasts (608) a repeating message identifying at least one broadcast content stream and, for each stream, a REGISTER (R) or DO NOT REGISTER (DNR) indicator. Mobile stations periodically re-examine (722) contents of this message. When the indicator is R for a broadcast content stream, mobile stations whose users have elected to receive it send (714) the base station a registration message for that stream. When the number of registered mobile stations reaches (612) a prescribed number, the base station changes (614) the indicator to DNR. When the indicator is DNR for a broadcast content stream, mobile stations refrain (712/716) from sending any registration message for that broadcast content stream.; The base station may institute a recount (618) by resetting the indicator to R.

Abstract: In a communication system (100), a method and apparatus provide for efficient control of call requests from mobile stations (102-104) to base station (101). Mobile station (102-104) receives an initial call request block probability from base station (101), determines an elapsed time from an effective time of the initial call request block probability, and adjusts the initial call request block probability based on an elapsed time. Mobile station (102-104) uses the adjusted initial call request to block call request.

Abstract: Systems and techniques are disclosed relating to communications. The systems and techniques include an input device, generating a time period in response to a broadcast channel selection from the input device, generating a request to register the broadcast channel if the time period ends before receiving a second broadcast channel selection, and transmitting the request to an access network. It is emphasized that this abstract is provided to comply with the rules requiring an abstract which will allow a searcher or other reader to quickly ascertain the subject matter of the technical disclosure. It is submitted with the understanding that it will not be used to interpret or limit the scope or the meaning of the claims.

Abstract: Providing for retransmission of SFN data, including SFN operated MBMS dat a, in a manner that preserves synchronization of scheduled SFN transmissions is disclosed herein. As an example, SFN data can be transmitted in a first allocation period, and an un-received or indecipherable SFN data packet asso ciated with the SFN data can be scheduled in a second allocation period. Mor e particularly, the un-received or indecipherable SFN data packet can be all ocated to a block of the second allocation period that is scheduled for non- SFN transmission, for instance. Accordingly, SFN retransmission can take pla ce on a cell by cell basis without substantially affecting SFN transmissions synchronized among the cells.

Abstract: Methods and apparatus are described for broadcasting content. Encoding the content to be multicast/broadcast into multiple streams, wherein at least one stream provides a base portion of the content, and additional streams provide enhancements to the content. A wireless communication device receives the broadcast and decodes streams in accordance with the reception capabilities of the wireless device. The configuration of the wireless device can be determined based on the wireless device's capability to decode multiple streams. In addition, the configuration of the wireless device can be determined based on a subscriber level of the wireless device.

Abstract: A Global System for Mobile Communications (GSM) network supports multi-carrier operation on the downlink and/or uplink for a mobile station. The mobile station receives an assignment of multiple carriers for a first link in the GSM network, receives an assignment of at least one carrier for a second link in the GSM network, and exchanges data with the GSM network via the multiple carriers for the first link and the at least one carrier for the second link. The first link may be the downlink and the second link may be the uplink, or vice versa. The mobile station may receive data on multiple carriers at the same time for multi-carrier operation on the downlink. The mobile station may transmit data on multiple carriers at the same time for multi-carrier operation on the uplink.
