摘要:
The present invention is a method and system adapted to facilitate, between a mobile station (MS) and network, an indication of support for reduced time transmission interval (RTTI). The MS can provide a base station system (BSS) with an indication of its multislot capability within an access burst sent at the start of a contention based access. In another aspect, the MS can indicate support for a new Immediate Assignment message as the conventional Immediate Assignment message can only assign single timeslots. The present invention enables the Radio Access Network (RAN) to assign RTTI and more than one timeslot for GPRS/EDGE temporary block flows (TBFs) during an Access Grant Channel (AGCH) assignment. The method of the present invention can be implemented in a computer program product or distributed software adapted to be loaded into at least one or a plurality of memory locations and executed by at least one or a plurality of respective computer processors.

摘要:
A method of accessing a communications channel, the method comprising: assigning a time transmission interval (TTI) and at least one temporary block flow (TBF) during an Access Grant Channel (AGCH) assignment; allocating an additional field in an Immediate Assignment message sent on the AGCH; using the additional field to simultaneously assign to a mobile station (MS) at least one temporary block flow on an uplink of the communications channel and at least one temporary block flow on a downlink of the communications channel.

Scheduling of a Temporary Block Flow in a wireless communication system, wherein a type of Temporary Block Flow supported in the wireless communication system is evaluated (310) and a set of packet data channels pre-assigned to the Temporary Block Flow is identified. For a type of Temporary Block Flow supporting dynamic scheduling, carrier scheduling is performed by identifying timeslots (320) available for packet data scheduling for the Transmission Time Interval, determining a new set of packet data channels for potential scheduling to the Temporary Block Flow in the Transmission Time Interval, wherein the new set of packet data channels may include time slots on any carrier(s), and specifying (330) the packet data channels selected for potential scheduling for the Temporary Block Flow as a subset of packet data channels within the pre-assigned packet data channels. Packet data channels are allocated (340) for the Temporary Block Flow in the Transmission Time Interval. The Temporary Block Flow is scheduled (350) to the set of packet data channels.

The invention discloses a method for use in a cellular system with an RBS which controls traffic to and from a cell, with one User Equipment, UE, in the cell. The RBS and the UE receive and transmit information between each other, one of them being a sending party and the other one is a receiving party, and errors in messages which are received can be detected by the receiving party by a first error detection method and if errors are detected in received messages, the receiving party can request a retransmission from the transmitting party. The receiving party stores the order in which retransmissions are requested, so that erroneous retransmissions may be detected by the receiving party without the first error detection method.

A method may include receiving, by a user equipment incapable of transmitting and receiving simultaneously, a schedule to transmit data on an uplink, detecting, by the user equipment, whether there is data to be transmitted on the uplink, and receiving, by the user equipment, during a time corresponding to the schedule, data associated with a downlink, when it is determined that there is no data to be transmitted.

The present invention pertains to the field of data communications and is directed to providing ways and means for flexible receipt reporting. A transceiving unit (1) is operated (61) to receive at least one sequence of data blocks (9) where the data blocks each have a respective sequence number (31). The receipt of the data blocks is monitored (63) to establish whether the data blocks have been successfully received or not. A receipt report is selectively generated (65) based at least in part on the performed monitoring. The receipt report includes at least one data part in accordance with a predetermined data format, which includes at least a first data portion (41) with information (BSN_NACK) identifying a sequence number of one data block in the sequence that has not been successfully received and a second data portion (43) with information (BSN_MAP) on whether or not successful receipt has been achieved for a number of data blocks in the sequence having sequence numbers following directly after the identified sequence number. The receipt report is provided in a generated data block (11) that is transmitted from the transceiving unit (1). The invention is applicable to all forms of data communications, including wireless data communications.
摘要:
The present invention relates to assigning addresses to communication devices in a radio access network and notifying communication devices of scheduled uplink transmission time periods. Related methods, communication devices and control units are disclosed. A method of assigning an address to a communication device in a radio access network for use in notification of scheduled uplink transmission time periods for the communication device is provided. The method comprises assigning to the communication device an uplink state flag (USF) value. Furthermore, the method comprises assigning to the communication device an extended USF (eUSF) value. The address assigned to the communication device is a combination of the assigned USF value and the assigned eUSF value. By means of the eUSF value, the normal address range provided by the USF is extended, thereby facilitating use of more communication devices in the radio access network.

摘要:
A method, in a base station subsystem (10), of allocating radio resources to mobile stations (20) in a wireless communication system (1) involves the base station subsystem (10) assigning a respective Temporary Block Flow (TBF) to each mobile station (20) in a cell (40) in the communication system (1), and then assigning to each TBF a Temporary Flow Identity (TFI), at least one Packet Data Channel (PDCH), and an Uplink State Flag (USF) if the TBF is an uplink TBF. The base station subsystem (10) then selects different training sequences from a plurality of available training sequences and assigns a respective different selected training sequence to two or more TBFs wherein these two or more TBFs share the same assigned Temporary Flow Identity (TFI), the same assigned Packet Data Channel (PDCH), and/or the same assigned Uplink State Flag (USF) if the TBF is an uplink TBF.
