摘要： In one embodiment, a method of operating a radio access node is provided. The method comprises determining whether support from a secondary cell is required for a wireless device to communicate with the radio access node, and, in response to determining that support from the secondary cell is required, calculating a modified channel condition outer-loop value for the secondary cell; and using the modified channel condition outer-loop value in an initial activation decision step for the secondary cell. The initial activation decision step may comprise activating the secondary cell in response to determining that the sum of a device reported channel condition value and the modified channel condition outer-loop value is above an activation threshold. Corresponding devices, computer programs and radio access nodes adapted to carry out the methods provided are also disclosed.

摘要： According to certain embodiments, methods and systems for toggling transmission parameters in a heterogeneous network to achieve a target block error rate by a network node may include obtaining a signal-to-noise ratio (SINR) estimate from channel quality information for a downlink between a network node and a wireless device. For each of a first code word and a second code word to be transmitted on the downlink, a block error rate estimate may be obtained based on the SINR estimate. The network node may then determine at least one expected SINR for the first code word and the second code word. The at least one expected SINR may be determined as a function of the SINR estimate and the block error rate estimate. Based on the at least one expected SINR for the first code word and the second code word, a modulation and coding scheme (MCS) for obtaining a target block error rate may be selected. The network node may then transmit the first code word on a first transmission layer and the second code word on a second transmission layer during a first transmission time interval. In a second transmission time interval, the network node may transmit the first code word on the second transmission layer and the second code word on the first transmission layer.

摘要： A radio resource management method is provided. Data for transmission is stored. The stored data is associated with user equipment (UE). A channel quality is estimated. A first modulation and coding scheme (MCS) is determined based at least in part on the estimated channel quality. A first number of scheduling blocks (SBs) required to transmit the stored data is determined based at least in part on the first MCS. The first number of SBs are a minimum of an initial number of SBs and available amount of SBs. A link quality is calculated based at least in part on a channel condition associated with the first number of SBs. A second MCS is determined based at least in part on the calculated link quality and a link quality requirement.

摘要： The present invention provides a method and apparatus for improving wireless communication network performance and efficiency, based on detecting the occurrence of grant loss in relation to the transmission of scheduling grants to mobile terminals over a downlink control channel. Grant loss detection is based on detecting erasure events corresponding to the transmitted scheduling grants, and the incidence of grant loss with respect to a given mobile terminal can be tracked and used to compensate the control value(s) used for link adaptation of the downlink control channel, with respect to that terminal. Additionally, or alternatively, when a given grant is determined to be lost, a new grant is sent and the HARQ redundancy version is reset for the newly scheduled transmission.

摘要： A method and system for connection management in a wireless data network, such as a 1×EV-DO network adds connections to new network sectors upon receipt of a connection request from an active terminal, but removes data connections that the active terminal requests to be dropped only after confirmation from the active terminal that a channel allocation message has been received and applied. The active network maintains an active set of connections that is at least as large as the active set maintained by the active terminal and does not initiate a connection termination if no confirmation of the channel allocation message is received. This allows for a reduction in the number of dropped connections.

摘要： In code division multiple access communication systems, there are three levels for updating locations of dormant mobile stations (MSs) and setting up fast call. In sector and are levels, the dormant MS send a layer 2 message containing a message type and MS identifier to a base transceiver station (BTS). Since the message is associated with the sector where the MS is located, the network is aware of the MS's location from the updated location. The dormant MS sends to the BTS a reconnect message containing a message type and an MS identifier. The MS's dormant to active state transition is initiated by the MS. In the communication network, sub-packet zone ID is broadcasted in the overhead message. The MS reports its location change on R-CSCH and the network with the BSC level control can page the MS within the zone where the MS sends the report.
