First and second groups of mobile terminal communications in a cell are defined. A basic frequency hopping sequence for both groups is identified. An offset from the basic hopping sequence is determined for each mobile terminal communication in the first and second groups and is used along with the basic frequency hopping sequence to generate an assigned frequency hopping sequence for each mobile terminal. Some of the assigned frequency hopping sequences overlap such that a first communication from the first group and a second communication from the second group simultaneously use the same time-frequency radio resource during one hop in their corresponding assigned frequency hopping sequences. The first and second mobile terminal communications use a different time-frequency radio resource during another hop in their respective assigned frequency hopping sequence thereby varying the offset for each mobile terminal communication in the second group to improve interference diversity between the two groups for each hop.

A method of transmitting a downlink, coding scheme CS-RLC/MAC control message from a BSS to an EGPRS MS (), and receiving and detecting the CS-RLC/MAC control message in the MS. The BSS places in an MCS-radio block, a CS-RLC/MAC control block identical to a coding scheme CS-RLC/MAC control message excluding the MAC header octet. The BSS also places a coding scheme CS-stealing bit code word in the radio block using legacy stealing bit values and positions. The CPS field () of the block header () indicates that the radio block contains a CS-RLC/MAC control message. The MS receives the radio block and detects the coding scheme CS-stealing bit code word. In response, the MS interprets the received radio block header to identify the CPS field. The MS determines from the CPS field that a CS-RLC/MAC control block has been received.

A handover or cell change procedure in a cellular radio communications system starts with mobile user terminal present in a serving cell and having multiple radio resources simultaneously allocated for communication with a base station of the cell. When there is a need for a cell change, the multiple radio resources are sequentially replaced with radio resources allocated to the terminal for communication with at least one base station having an associated cell different from the serving cell. This cell change procedure provides macro diversity without requiring the complexity of soft handover and has enhanced service coverage and handover robustness compared to hard handover.

A method and apparatus for determining the content in bursts to be transmitted from a base station in a mobile network on a broadcast frequency in specific timeslots of a broadcast frequency frame structure. A current state of the logical channel allocated to the forthcoming burst is checked, and the content in the forthcoming burst is determined depending on the current channel state. A dummy burst with a base station specific training sequence is transmitted if there is no data to transmit, and if the dummy burst cannot be confused with a regular traffic burst according to the current channel state. The dummy burst contains no intelligible information to mobile terminals.

The invention involves selection of modulation scheme for a mobile unit () having access to a link quality enhancing algorithm () operable only on data modulated using a subset of the available modulation schemes. The mobile unit () performs signal quality measurements on a communications link (), over which data modulated with a first modulation scheme is communicated. A link quality measure is then determined for this first modulation. A quality enhancement due to operation of the algorithm () is also determined. This quality measure and the quality enhancement are used for generating decision information, which is reported to the network (). There the information is used for estimating link quality measure(s) of currently non-employed modulation(s) for the mobile unit (). The selection of a modulation scheme for the communications link is then performed based on the decision information and the estimated quality measure(s).

The detector signals are compared and the minimum value of the compared detector signals () is selected for all time frames, giving rise to a first output signal () comprising the minimum values from the first and second detector signals ().

Flexibly configurable layer one transport channels produce radio blocks in response to communication information and extract communication information from radio blocks. Each transport channel can include an encoder or a decoder coupled to and cooperable with a data puncturer or a data repeater. An information source can produce for each transport channel first configuration information and second configuration information, wherein the first configuration information is indicative of how the associated transport channel is to be configured if a first modulation type is used for a current radio block, and wherein the second configuration information is indicative of how the associated transport channel is to be configured if a second modulation type is used for the current radio block. The physical layer can include a description information source that provides description information from which various configurations of the transport channels can be determined. The description information source provides the description information in the physical layer in response to further information which the description information source receives from a higher layer and which is indicative of a service request initiated by a communication network.

Flexible layer one for radio interface to PLMN

A network node () of a wireless telecommunication network () uses a first coding scheme (selected from plural possible coding schemes) for encoding of a point-to-multipoint (PTM) transmission carried to plural mobile stations () on a common downlink channel (). The mobile stations () receiving the point-to-multipoint transmission on the common downlink channel () evaluate the link quality of the point-to-multipoint transmission. Feedback from the plural mobile stations () regarding the link quality of the point-to-multipoint transmission is provided to the network node () on a common uplink channel (). A controller () at the network node () monitors information received on the common uplink channel for feedback regarding the link quality of the point-to-multipoint transmission. The controller () at the network node () uses the feedback to determine whether to change from the first coding scheme to a second coding scheme for the encoding of the point-to-multipoint transmission to the plural mobile stations ().

Link adaptation for point-to-multipoint channel

Flexibly configurable layer one transport channels produce radio blocks in response to communication information and extract communication information from radio blocks. One of the transport channels can be enabled to extract its associated communication information from a radio block while another of the transport channels is maintained disabled. The one transport channel provides the extracted communication information to a decision maker in a higher layer. In response to the extracted communication information, the decision maker decides whether the other transport channel should be enabled, and provides to the physical layer an indication of its decision.

Control signalling for systems employing link adaptation and incremental redundancy is described. A link adaptation/incremental redundancy message can be transmitted from a receiving entity to a transmitting entity to inform the transmitting entity of the receiving entity's incremental redundancy status or preference. Another message, which indicates whether resegmentation should be performed for retransmitted blocks can also be transmitted from a receiving entity to a transmitting entity. Both of these messages can be used by the transmitting entity to determine an appropriate modulation/coding scheme for subsequent transmissions of both original data blocks and retransmitted data blocks. The messages can be used together or independently in either link (uplink or downlink) between a base station and a mobile station in a radiocommunication system.
