摘要:
The invention provides a method for transmitting a serving grant to a base station. In some embodiments the method includes: storing a serving grant in a storage unit, generating a layer two protocol data unit (L2 PDU); and transmitting the L2 PDU to the base station, wherein the step of generating the L2 PDU comprises adding the serving grant to the L2 PDU.

The access of a user equipment, UE, (10) configured for and activated to implement extended access barring, EAB, or included in a group of UEs addressed via group paging to a wireless communication network (20) is controlled. First, an access delay for the UE is determined. Second, a timing of an attempt by the UE to access a cell in the wireless communication network is controlled based on the determined access delay. Many example embodiments are described.

A new set of random-access preamble signatures are introduced to differentiate new-release UEs from UEs compliant only with earlier releases. Additional new features of a random-access procedure are also disclosed, including an ability to deploy multiple transmission-time-intervals TTIs) in a given area. An example mobile terminal, according to some embodiments of the present invention, selects a TTI from two or more possible TTIs. The mobile terminal then selects a preamble signature from a group of one or more preamble signatures associated with enhanced-uplink resources and associated with the selected TTI, and transmits a random-access channel (RACH) preamble, using the selected preamble signature. In some embodiments, the mobile terminal selects between a 2-millisecond TTI and a 10-millisecond TTI.

Embodiments herein relate to a method in a network node (12,14) for signalling Hybrid Automatic Repeat Request, HARQ, configuration for a common enhanced dedicated channel configuration in a radio communications network (1). The network node (12,14) is comprised in the radio communications network (1) and serves a user equipment (10). The network node (12,14) determines a state of a HARQ process of a transmission time interval out of a number of HARQ processes for a common enhanced dedicated channel configuration. The state is defining whether the HARQ process is active or inactive. The network node (12,14) signals the HARQ configuration for the common enhanced dedicated channel configuration by broadcasting a value representing the state of the HARQ process.

摘要:
The present invention relates to fast random access methods and arrangements for the enhanced uplink dedicated channel of E-UTRAN (Evolved Universal terrestrial radio access network). A user equipment (UE) being in a low activity state sends a random access request comprising a preamble on a physical random access channel (PRACH) to a NodeB. The NodeB receives the request and sends in response to the received random access request a response comprising information associated with detection of the preamble on an acquisition indicator channel (AICH). The response comprises further in an extension of the AICH an indication of an action to be taken by the UE. In an embodiment of the present invention the action is to access the E-DCH and the response comprises configuration parameters to the E-DCH.
摘要:
A method, apparatus, and system are described relating to at time when a wireless terminal reports an event to a network. An event to be reported to the network is detected by the wireless terminal. A communications condition affecting a communication between the wireless terminal and the network is determined, and based on the detected communications condition, a dynamic time-to-trigger period is adjusted so that the event is reported by the wireless terminal to the network before the time-to-trigger period expires.

Embodiments herein relate to a method in a mobile terminal (10) for requesting access to a wireless communication system. The mobile terminal (10) receives broadcasted system information directly indicating first access request preambles for a first contention based channel, and indirectly indicating second access request preambles for a second contention based channel based on the directly indicated first access request preambles. The mobile terminal (10) further derives the second access request preambles from the first access request preambles. Additionally, the mobile terminal requests access using the second access request preambles or the first access request preambles to access the wireless communication system.
摘要:
Embodiments herein relate to a method in a mobile terminal (10) for requesting access to a wireless communication system. The mobile terminal (10) receives broadcasted system information that indicates a first available resource of a contention based channel. The mobile terminal (10) derives a second available resource of the contention based channel based on the first available resource of the contention based channel. The mobile terminal (10) further transmits an access request preamble mapped to the second available resource to access the wireless communication system.
