Abstract: The invention provides, according to one aspect, a method of scheduling information in a communication system at serving cell change. When a serving cell changes for a user equipment (UE), it is determined whether the new serving cell belonged to the previous serving enhanced data channel (EDCH) radio link set (RLS). The user equipment then sends scheduling information (SI) in the first MAC-e protocol data unit (PDU) sent in uplink after completion of the serving cell change only when it is determined that the new serving cell did not belong to the previous serving EDCH RLS. In other words, the UE sends the SI at serving cell change only when the base station (node B) has also changed.

Abstract: A communication flow for HSUPA is shown that allows a NodeB to measure the thermal plus background noise level (Prx—noise), and at the same time which also allows the RNC, according to its own (centralized) strategy, to overwrite the very same value that is then used in NodeB (de-centralized) scheduling.

Abstract: In accordance with aspects of the present invention, a method, apparatus and system for non-contention based handover based on pre-reserved target cell uplink allocations in communication systems. In one embodiment, the apparatus includes a transceiver (760) configured to communicate with a source base station and a data processor (750) coupled to the transceiver (760). The data processor (750) is configured to produce a measurement report based on a signal received from the source base station, initiate transmission of the measurement report to the source base station, process a handover command received from the source base station, and enable transmission of access bursts to a target base station in a reserved window of time on an uplink shared channel.

The indication is sent to a network element capable of decoding it for analysis.

Abstract: A method of scheduling transmission of data in a wireless communication network comprising: establishing a data channel for transmitting user data from a user equipment to a network entity, establishing a signalling channel for transmitting signalling data from a user equipment to a network entity, transmitting over said signalling channel from the user equipment a first rate request message requesting additional resources from the network for transmission of data at an increased data rate over said data channel, maintaining said signalling channel for a period awaiting a rate grant message, and transmitting a second rate request message over said signalling channel during said period.

Abstract: A method by which a UE device and a Node B communicate information such as scheduling information to each other, including a step of sending the information as part of a communication signal instead of padding in the communication signal if the information can be fit by removing all or part of the padding.

User equipment is configured a monitor a usage of a plurality of buffers, detect one of a plurality of pre-selected conditions corresponding to at least one of the plurality of buffers, designate one of a plurality of buffer status reporting formats depending on the pre-selected condition detected, communicate a buffer status report to a network device in accordance with the buffer status reporting format designated. The buffer status reporting format is configured to minimize buffer status reporting overhead created by the communicating of the buffer status report.

Abstract: An optional short SACCH is used when the network detects high error rate in the normal SACCH channel. The communication returns to normal mode when the network detects that the link quality has improved. In the short SACCH message only the most relevant information fields are sent. The extra bits are used for channel coding so that in the channel conditions where the most robust AMR codings still work, the BLER of short SACCH is still tolerable.

Abstract: A method and a device for transferring signalling information in a TDMA based system. Temporal alignment of values for a retransmission number parameter (R) with the TDMA frame structure is determined on the basis of which a first radio packet to be sent in a number of first TDMA frames is encoded by using a certain first value for the parameter and a second radio packet to be sent in a number of second TDMA frames is encoded by using a certain second value for the parameter. The first and second radio packets are transmitted to the recipient that adheres to the same temporal alignment rules and can thus properly decode both the packets. The solution can be utilized especially in GERAN radio access network with FLO (Flexible Layer One) for transferring signalling information on half-rate channels.

Abstract: A set of power control step size increments are determined such that at least two step size increments differ from one another. The set is sent to a Mobile Station MS. A first power command to the MS informs of a first power for a uplink data transmission on a radio resource (E-DPDCH). To change power on the same radio resource, an offset is computed, the set of step size increments is accessed to determine which one, or combination of them, yield the offset, and the MS is informed of the second power by a second message that identifies those elements of the set that alone or in combination yield the offset. The MS determines the second power as a function of the first power and the step size increment(s) from the second message.

Abstract: In the LAPDm a short message service is implemented by pre-emption of every second signalling message when there is a short message to be sent. Same pre-emption mechanism is also needed when the RLC/MAC protocol is used on the data link layer instead of the LAPDm. The mechanism is provided by defining at least two different identities to be used with frames transmitted on the signalling channel; and pre-empting frames on the MAC at least on the basis of the identity relating to a frame. The identities are preferably identified on the basis of the signalling radio bearer of the frame.

Abstract: The invention relates to a method for improving the quality of control signalling based on signalling messages controlling speech or data transmission over an air interface between at least two radio terminals of a radio communications system, said speech or data being transmitted in at least one traffic channel of said radio communications system, and said signalling messages being transmitted in control channels associated with said at least one traffic channel. In order to allow for an improved performance of SACCH and FACCH, a first and a second signalling message with identical content are transmitted in two separate associated control channels. Alternatively, a signalling message included in a single ACCH is coded with a stronger coding. The invention relates equally to corresponding radio terminals and modules for such units.

Abstract: A network schedules a mobile station for an uplink packet transmission on a data channel, receives from a mobile station an uplink message on a control channel, determines from the uplink message a desired power for the mobile station to transmit on the data channel, and thereafter transmits to the mobile station a power control message that commands either a zero power allocation or a full power allocation for the scheduled uplink packet transmission. The mobile station receives from the network the power control message, then determines from the power control message whether zero or full power is allocated. If zero power, then the mobile station suspends its transmissions on the data channel until receiving a new power control command for uplink transmissions on the data channel. If full power, the mobile station transmits user data on the data channel without regard to power on a control channel.

Abstract: A method and a device for reconfiguration in a wireless system utilizing flexible layer one (FLO). In proposed solution one TFC (Transport Format Combination) is selected and reserved (504) exclusively for signalling use. The TFC may contain only one active transport channel and always utilize the same CRC and transport block size in order to unambiguously define the proper settings for signalling. Considering uplink transmission in a wireless system and special case of TFCI (Transport Format Combination Identifier) size change due to the TFCS (Transport Format Combination Set) reconfiguration that also generates a need to switch to a new dedicated basic physical subchannel (DBPSCH); whenever the network notices that the mobile station does not switch to the new DBPSCH (518), it concludes that the TFCS reconfiguration message sent was lost and stays with the existing configuration (520). Otherwise the new configuration is taken into use (514).

Abstract: Multiple transport channels (405, 406, 407) are multiplexed and transmitted in a single physical channel. A code (TFCI) is added to the transport channel data flows to indicate which processing schemes, from a set of available schemes, are being employed and the resultant blocks are interleaved. The depth of the interleaving is set in dependence on the transmission time intervals associated with the schemes in the set of processing schemes.

Abstract: A method is described which provides a synchronized HO of a mobile device. The method includes receiving a HO command. A determination is made of whether the HO command includes an indication of UL resource allocations. A C-RNTI is waited for in DL signaling if the HO command does not include the indication of UL resource allocations. If the HO command includes the indication of UL resource allocations, transmitting occurs based on the UL resource allocations. The method may be performed as a result of execution of computer program instructions stored in a computer readable memory medium. An apparatus is also described.

Abstract: A system and methods for slow medium access control entity (MAC-e) for autonomous transmission during High Speed Uplink Packet Access (HSUPA), and for service specific transmission time control in HUSPA, wherein a control parameter that is independent from the air interface transmission time interval (TTI), hybrid automatic repeat request (HARQ) processes or enhanced dedicated transport channel (E-DCH) scheduling is used. This control defines the minimum time interval between subsequent new transmissions. The control has no impact on retransmissions, which are performed normally.
