摘要:
A method for operating a multiple point transmission system is disclosed. The method includes reconfiguring the multiple point transmission system according to an updated configuration of an at least one radio bearer between an at least one transmission point and a terminal device, and communicating with the terminal device using the reconfigured multiple point transmission system. The configuration of the at least one radio bearer is updated according to operating condition information of the terminal device.
摘要:
The PDCAB packet (300) and the RRA packet (308) are transmitted together on the F-SCCH. For example, 9 RRA bits (305) are appended to the PDCAB field (303), in place of the pad bits (205), thereby allowing both the PDCAB (303) and RRA (311) messages to be protected against errors by a 16-bit CRC (307). In accordance with the embodiments, a receiver is able to distinguish between the varying PDCAB (303) and RRA (305) message formats and transmitting the packets (300) and (308) together is a normal mode of operation in the embodiments. Therefore, in accordance with the embodiments, when the PDCAB packet (300) and RRA packet (308) are transmitted together, the network replaces the N PDCAB pad bits, such as pad bits (205), with the first N bits from the RRA bitmap (311), in order to use the nominal CRC length for both packets (300) and (308).

A method of selecting a private cell for providing communication to a communication device (222) in a communication system (200) comprising a plurality of private cells (202, 204, 206, 208) comprises identifying (400) private cells available to the communication device for establishing communication, determining (402) a priority value from a plurality of priority values for each of the identified private cells for the communication device, and selecting (404) a private cell for providing communication from the identified private cells according to the determined priority values of the identified private cells. Each private cell may be associated with a predetermined type of private cell for the communication device. The priority values for each of the identified private cells may then be determined according to the predetermined type associated with the identified private cell. A method of synchronising a priority value of a private cell determined by the communication device with a priority value of the private cell determined by a network (218) is also disclosed.
摘要:
A method, a mobile system, and a home network base station are disclosed. A mobility management entity 502 may receive a notification of a connection attempt by a mobile system 104. The mobility management entity 502 may generate a network access message element 650 having a bearer protocol parameter. The mobility management entity 502 may send the network access message element 650 to the mobile system 104 via a home network base station 110. The mobile system 104 may use the bearer protocol parameter to establish packet data network connectivity with a home network 108 associated with the home network base station 110. The mobile system 104 may determine a traffic bearer for a data traffic set based on the bearer protocol parameter.
摘要:
A system, method, and apparatus for establishing headroom for a mobile station operating in a wireless communication system by determining (230) a communication channel variance condition and establishing (245) a headroom value based on the communication channel variance condition. The headroom value may be further revised by determining (260) if a battery condition in a mobile station relates to a low battery level and increasing (265) the headroom value in order to decrease the maximum data rate. Modifications to headroom allow data rates to be tailored to specific channel variance conditions and battery conditions.
摘要:
A receiver and method for recovering transmitted symbols in a H-ARQ packet retransmission. The method includes receiving a communication signal; determining components of the signal that are not attributed to the desired symbols; removing the unwanted components from the signal to generate a modified communication signal; determining the effective channel impulse response for the modified communication signal; generating a block filter using the effective channel impulse response; and filtering the modified communication signal using the block filter to remove the inter-code interference in the modified communication signal and recover the desired symbols.
摘要:
A method in a wireless communication network infrastructure entity including broadcasting information on a broadcast channel for receipt by broadcast wireless communication terminals in the wireless communication network, transmitting (210) a report triggering command to the wireless communication terminals, wherein the report triggering command triggers reporting of feedback information for the channel by the wireless communication terminals upon satisfaction of a condition.
摘要:
A method of operating a network infrastructure entity in which a mobile communication device is capable of handover from a first wireless communication network to a second wireless communication network is described. System information of the second wireless communication network is broadcast, over a control channel of the first wireless communication network, to a plurality of mobile stations communicating with the first wireless communication network. The system information includes a system time of the second wireless communication network measured at a predefined time point of a frame structure of the first wireless communication network and at a transmitter of the first wireless communication network. The system information may further include neighbor cell information and slot offset of control channel.
摘要:
A call in progress in a first communication network is handed over to a second communication network which uses a different air interface. To facilitate the handover, the present serving base station commands the mobile communication device to take measurements of surrounding cells of the second communication network. The measurements are sent along with a handover request from the serving base station to a radio network controller of the second network, which decides upon a cell to which the cal will be handed. A grant message including an identifier to be used by the mobile communication device and an identifier of the base station receiving the handover is transmitted back to the first network, and used by the mobile communication device in handing over the call.
