摘要:
It is presented methods and apparatuses for uplink resource utilization in a telecommunication system. More particularly, embodiments disclosed herein relate to a method performed in a user equipment (4), said user equipment (4) having data (Di) ready to transmit, the data pertaining to a traffic class (i). The method comprises establishing a connection with a radio network node (2) and receiving threshold parameter sets (Thi) from the radio network node (2). Each threshold parameter set (Thi) comprising at least a minimum size limit (Si) associated with respective traffic class (i). The threshold parameter sets (Thi) are used to determine if the amount of data that the user equipment (4) has ready to transmit is large enough to be transmitted or if it has been waiting long enough to be transmitted. If it is the UE (4) transmits the data to the radio network node (2). There are also presented a corresponding method performed in the network node (2) and a user equipment (4) and a network node (2) for performing the methods.

Two User Equipment (UE) operate in a Near Companion Mode (NCM), in which a monitoring UE (MUE) monitors an uplink transmission opportunity granted to its companion UE (CUE) on a shared uplink channel. If the CUE does not begin transmitting within a predetermined portion of its transmission opportunity, the MUE may utilize the transmission opportunity to transmit an uplink data packet. In one embodiment, where the CUE does not have data to transmit, it may transmit a predetermined pattern at the beginning of its transmission opportunity, to indicate to the MUE that the transmission opportunity is available. The MUE may transmit an NCM radio block using the entire symbol space associated with the last three of four bursts allocated to the CUE, or using a newly defined NCM format comprising four abbreviated bursts, using only a portion of the symbol space associated with the four bursts corresponding to the transmission opportunity allocated to the CUE.

In a cellular radio system cell identities, in particular E-UTRAN PCIDs, are grouped in accordance with the area (e.g., Tracking Area), to which they belong to in a message transmitted from a radio base station to a mobile station. In one embodiment the grouped cell identity information is transmitted as a broadcast message. A multi RAT (e.g., GERAN/E-UTRAN) capable mobile station receiving such a broadcast message where the IDs are grouped together in tracking area groups is then enabled to determine the neighboring cells that belong to the same area. When cell reselection to an E-UTRAN cell is rejected due to a Tracking Area not being allowed, the mobile station can then be allowed to directly initiate cell reselection to E-UTRAN cells that are not part of the same PCID group, and which do not belong to the same tracking area.

By allowing the option of placing an Logical Link Control (LLC)-entity within the Base Station Subsystem (BSS) an improved system performance in the form of mobile stations experiencing reduced information acquisition times can be achieved by using a cache memory in the BSS. A method in the BSS can include receiving one or more LLC Packet Data Units (PDUs) from a mobile station, and extracting Sub Network (SN)-PDU(s) contained in each LLC PDU and reassembling the SN-PDU(s) to recover a single N-PDU. The N-PDU is determined to include a request for information using an LLC entity in the base station subsystem. Content of a cache memory in the base station subsystem is determined to correspond to the request for information indicated by the N-PDU. A response to the request for information from the mobile station is made using the content of cache memory in the base station subsystem.

A method may include receiving, by a user equipment incapable of transmitting and receiving simultaneously, a schedule to transmit data on an uplink, detecting, by the user equipment, whether there is data to be transmitted on the uplink, and receiving, by the user equipment, during a time corresponding to the schedule, data associated with a downlink, when it is determined that there is no data to be transmitted.

A method in a user equipment for handling cell selection is provided. While in dedicated mode the user equipment receives from a radio network node a measurement information message which indicates at least two frequencies associated with a respective cell in a respective radio access technology. While it is in dedicated mode, the user equipment performs measurements on the frequencies to obtain a respective measurement value for each one of them, and receives a selection indicator message comprising a respective priority for each one of the frequencies. The user equipment obtains a respective threshold value for each of the frequencies and successively evaluates the frequencies in descending priority order until a frequency is determined for which the measurement value exceeds its respective threshold value. When entering idle mode, the user equipment selects cell based on the evaluation.

In one aspect, the invention provides apparatuses and methods for wirelessly transmitting application data utilizing priority information for each radio link control (RLC) data block transmitted. Advantageously, the application data with a relatively high transmission priority is not substantially delayed by the transmission of application data with substantially lower transmission priorities.

A method, node, and system are provided that overcome problems with using inaccurate estimates of a current round trip time RTT for verifying the ACK/NACK information received in an ACK/NACK report, e.g., a piggy-backed ACK/NACK (PAN). This is accomplished by de-coupling the RTT from the ACK/NACK analysis performed in the sending node that receives the ACK/NACK report. As a result, unnecessary re-transmissions are avoided, communication delays are decreased, and spectrum and other system resources are used more efficiently.
摘要:
A device type-dependent approach to access control is used to independently control network access by machine-type communication (MTC) and non-MTC devices. A plurality of access classes are defined for each device type. The base station selectively controls access to the network by each device type by sending an access control mask for each defined device type to the wireless terminals within the network.
