Data Block Transmission with Variable Retransmission Feedback Time For communicating data between a transmitter (10) and a receiver (14), wireless transmission of data blocks is implemented on the basis a retransmission protocol with variable value of a feedback time. The feedback time defines a time interval between transmission of one of the data blocks (22) and transmission of a feedback message (23) indicating whether the data block (22) was successfully received. The transmitter (10) or the receiver (14) determines the value of the feedback time. Depending on the determined value of the feedback time, the transmitter (10) controls transmission of the data block (22) to the receiver and/or the receiver (14) controls reception of the data block (22) at the receiver (14). The transmitter (10) may for example be a base station of a mobile network, and the receiver (14) may be a terminal device connected to the mobile network. (FIG. 1)

Novel techniques of access network selection in multi-access network environment are provided, which allow for avoiding access selection loops for independent access selection processes. The multi-access network environment provides a first access selection function, e.g. a 3GPP access selection function, and a second access selection function, e.g. an ANDSF based access selection function. At least a portion of the first access selection function (565) may be implemented by a network component (560). At least a portion of the second access selection function (110) may be implemented by a user equipment (100), e.g. a mobile terminal. According to the proposed concepts, a selection priority information of the first access selection function (565) is made available to the second access selection function (110).

In an example embodiment, a network node transmits secondary signal component of a combined wireless communication signal to a user equipment. The combined wireless communication signal includes the secondary signal component and a primary signal component. Secondary pilot resources of the secondary signal component are dynamically shifted relative to primary pilot resources of the primary signal component by an amount that is based on whether a current estimation procedure at the user equipment is a primary channel estimation procedure or a secondary channel estimation procedure. In a corresponding example embodiment, the user equipment receives the combined wireless communication signal with the dynamically shifted pilot resources. The user equipment estimates the primary channel in the primary channel estimation procedure and estimates the secondary channel in the secondary channel estimation procedure.

A method for a client node (D100) to access an information object (102) located at a node (D500) of a secured network (120) via a network of information (100) wherein information objects (102) are identified by information object identities (IDObj, ID′Obj) and wherein nodes are identified by locators (LGW, LObj), wherein the following is performed at a routing node (D102): —receiving from the client node (D100) an information object identity related to the information object (102), —sending the information object identity to a resolving node (D400) of the network of information (100), the resolving node (D400) being capable of initiating a procedure for sending to the routing node (D102) a locator of a gateway node (D200) interfacing the network of information (100) and the secured network (120), —receiving the locator of the gateway node (D200), —sending a request for the information object (102) to the gateway node (D200) according to the locator, —receiving the requested information object (102) from the gateway node (D200), and —sending the information object (102) to the client node (D100).
摘要:
Disclosed herein is a method and a Radio Resource Management arrangement in a wireless communication system for allocating communication of one or several services to at least one of several available frequency spectrum resources. The method comprises the steps of categorizing said available frequency spectrum resources with respect to volatility, and categorizing said one or several services with respect to compressibility, and assigning said one or several services to the available spectrum resources such that compressible services are assigned to volatile spectrum resources.

The present invention relates to a method and a secondary user enabling secondary usage of radio resources owned by a primary party. The present invention also relates to a primary party and a broker. The secondary user is adapted to obtain radio resource allocation information transmitted from the primary party. It is further adapted to identify radio resources available for secondary usage based upon the radio resource allocation information. It is finally adapted to engage in communication over at least part of the radio resources identified as available for secondary usage.

The invention relates to transmitting data elements of a data stream based on a priority and target buffer fill levels at a receiving device. A transmitter controller transmits data elements of a data element class with a highest priority first, for reaching an associated buffer fill level and then turns to data elements of successively lower priorities, until the available bandwidth is exhausted.

The present invention aims at an effective approach to radio access system attachment in a heterogeneous communication network environment. According to the present invention, cooperation between different radio access systems is executed to advertise one radio access system in another. After receipt of a secure advertisement from a control unit of the advertising radio access system, a broadcasting unit of the receiving radio access system broadcasts advertisement information in relation to the secure advertisement in the communication network. Therefore, according to the present invention, a user terminal may at any time receive broadcasted advertisement information while establishing a trusted relationship with advertiser.
