Method and transmitting node for adjusting transmission over xDSL lines connected to the transmitting node. The method involves transmitting (1006) a first signal A1 on a first line (304), and transmitting (1008) a second signal A2 on a second line (306), the second signal A2 being related to the first signal A1. The method further involves adjusting (1010) the transmission of the second signal A2 on the second line (306), such that a contribution from the second signal A2 interferes constructively with a signal A1′ at the second end (304:2) of the first line (304), where the signal A1′ represents the signal A1 having propagated through the first line.

A method in a base station for selecting a set of transport format schemes for a cell is provided. The set of transport format schemes shall be used for a radio transmission from a communication device to the base station. The base station is serving the eel! comprising the communication device. The communication device is unsynchronized for transmission to the base station. The base station specifies (201) a plurality of sets of transport format schemes. Each set of transport format schemes is associated to a respective guard time, which guard time is a time margin required to compensate for the communication device being unsynchronized for transmission to the base station. After determining (203) a required guard time as the maximum timing advance value used in the cell the base station selects (204) one set of transport format schemes from the plurality of sets of transport format schemes to be available for the cell. The set is selected such that its associated guard time matches the determined required guard time in the cell.

Techniques provide additional Hybrid-ARQ indication resources for LTE TDD subframes that are normally without conventional LTE PHICH resources or that have too few LTE PHICH resources. In some embodiments, a modified PHICH is created using unused REGs in the control region of the downlink subframe. In others, a modified PHICH resides within the resources of an AL=1 PDCCH, and is formed using encoding and modulation processes that differ from normal PDCCH processing. In other embodiments, the PUSCH HARQ feedback bits are carried by a conventional LTE PDCCH, which is distinguished from other PDCCHs by scrambling it with a new type of RNTI: HARQ indicator Radio-network temporary identifier (HI-RNTI). In still other embodiments, the modulation symbols of PHICH are then placed on top of those normally reserved for PDCCHs. For such overlapped radio resources, the modulation symbols from the modified PHICH will replace those from normal PDCCHs for transmission.

The present invention relates a User Equipment, UE (204) and a Radio Base Station (202, 206) and methods therein for contention resolution in general. Based on measured and analyzed measurements of a radio connection establishment response from each of at least a first and a second Radio Base Station, a UE receiving said radio connection establishment response can resolve the contention by selecting a RBS based on the received power of a set of DL reference signals as received by the UE, of the received power of the radio connection establishment responses, on timing of the received sets of reference signals, on timing of the radio connection establishment responses, on historic RBS selections, on priority level of the RBS, to mention a few alternatives.
摘要:
In data transmission between a mobile network and a terminal device an uplink control channel resource is allocated to the terminal device and to at least one further terminal device. Further, a shared identifier is assigned to both the terminal device and the at least one further terminal device. Using the allocated uplink control channel resource, the mobile network receives a scheduling request from the terminal device. In response to receiving the scheduling request, the mobile network sends an uplink grant. The uplink grant is addressed by the shared identifier to the terminal device and to the at least one further terminal device. Further, the mobile network receives uplink data from the terminal device, which is accomplished on uplink resources indicated by the uplink grant.

Some embodiments herein relate to method in a user equipment (10) for determining a transmit power to be used by the user equipment when transmitting in a radio communications network, which user equipment (10) is served by a radio network node (12,12′) in the radio communications network. The user equipment (10) receives, from the radio network node (12,12′), an indication indicating a set of power control parameters out of multiple sets of power control parameters, which multiple sets of power control parameters are stored at the user equipment (10). The user equipment (10) determines a transmit power based on the indicated set of power control parameters.

A radio communication system and a method for assigning a short-lived Cell Radio Network Temporary Identifier (C-RNTI) to a first user equipment performing random access to a radio network node are provided. The radio communication system registers the first user equipment as connected to the radio network node. A message for synchronizing the radio network node and the first user equipment with respect to the first time period is transferred. After the first time period has elapsed, the radio communication system maintains the first user equipment connected to the radio network node, and allows the short-lived C-RNTI to be assigned to a second user equipment. Furthermore, a first user equipment and method for enabling assignment of a short-lived C-RNTI to the first user equipment performing random access and a radio network node and method for assigning a short-lived C-RNTI to a first user equipment performing random access are provided.
