The first user equipment (121) determines that a valid timing reference is not present in the first user equipment (121). Also,the first user equipment (121) determines whether a preconfigured timing advance can be used in the D2D communication. Then, when determined that the preconfigured timing advance can be used, the first user equipment (121) transmits a D2D signal to the second user equipment (122) with a timing using the preconfigured timing advance to perform D2D communication. A user equipment (121), a network node (110)and method therein for enabling D2D communications between user equipments (121, 122) in a radio communications network (100) are also provided.

摘要： The present disclosure relates to a technique for avoiding, forestalling, or reducing re-establishment procedures in a telecommunications system having multiple carriers. A method aspect of this technique includes monitoring a signal quality of an anchor component carrier associated with a serving cell of a mobile terminal and used by the mobile terminal. If the signal quality of the anchor component carrier violates a first signal quality condition, then a parameter (of, e.g., a downlink signal) of at least one candidate component carrier associated with the serving cell and distinct from the anchor component carrier is measured and the signal quality of the at least one candidate component carrier is determined based on the measured parameter. If the determined signal quality fulfils a second signal quality condition, then reselection to the at least one candidate component carrier is initiated such that the candidate component carrier becomes the anchor component carrier associated with the serving cell and used by the mobile terminal.

摘要： A half-duplex mobile terminal having first and second receiver branches connected, during a receive mode, to respective antennas, is disclosed. One of the antennas is selectively connected to the first receiver branch or to a transmitter circuit. The first antenna is connected to the first receiver branch during a first interval, during which interval data is detected using outputs from both the first and second receiver branches. The first antenna is disconnected from the first receiver branch at the end of the first interval, and, during a second interval immediately following the first interval, data is detected using the output of the second receiver branch. A portion of the incoming transmission that arrives during the transition between the receive mode and transmit mode in a half-duplex transceiver is thus received and detected, improving performance of the half-duplex transceiver.

摘要： Wireless communication method and system for improving optimal antenna weight derivation in transmit diversity mode during soft handover. The method and system use scale factors that depend on the reliability of the feedback information (FBI) detection on the uplink. Depending on FBI detections for each link, the scale factors are then applied to the downlink channel response estimates. FBI detection performance may be based on downlink antenna verification, downlink transmit power control command "up/down" ratio, or both. Poor antenna verification or a high number of "power up" commands on the uplink may indicate unreliable FBI detection. By applying higher scale factors to downlink channel responses corresponding to reliable FBI detection, better closed transmit diversity performance during soft handovers may be achieved. This Abstract is submitted with the understanding that it will not be used to interpret or limit the scope or meaning of the claims.

摘要： A radio signal that has been received from a channel is equalized by estimating the channel, generating an initial estimate of a DC-offset that has been introduced into the radio signal, and estimating a variance of the initial estimate of the DC-offset. The channel estimate, the initial estimate of the DC-offset and the estimated variance are then used to determine a most likely symbol represented by the radio signal. The initial estimate of the DC-offset that has been introduced into the radio signal may be determined from a training sequence portion of the received signal and a reference training sequence signal. For example, a least squares technique may be used to generate the DC-offset as well as the channel estimate and the variance of the initial estimate of the DC-offset. In an equalizer section, the DC-offset and variance values are taken into consideration when the most likely symbol represented by the radio signal is decided.

摘要： One aspect of the teachings herein involves the advantageous use of learned statistical information to improve inter-cell interference coordination, "ICIC". A network (20) uses historical signal quality measurements collected over time for wireless communication devices (36) operating within its coverage areas to identify those geographical areas where devices (36) generally experience significant levels of patterned interference. In an example case, the network (20) develops a "map" of the geographical areas that are affected by the transmission patterns of neighboring nodes (26, 30), and it applies the map to ICIC operations, wherein the serving nodes associated with the affected areas incorporate knowledge of the interfering transmission patterns into the ongoing scheduling of devices (36) operating in the affected areas.

摘要： A network node that serves a host cell in a cellular communication system transmits, at (a) first time interval(s), first control channel information on a control channel that extends over a first bandwidth of a radiofrequency spectrum. The first control channel communicates information necessary to enable a first type of communication device to receive data from the host cell. The first type of communication device can receive first bandwidth-wide signals. At (a) second time interval(s), second control channel information is transmitted on a second control channel of a first M-cell. The second control channel occupies a second bandwidth that is smaller than the first bandwidth. The second time interval(s) do(es) not coincide with any of the first time interval(s). A second type of communication device having reduced receive bandwidth capabilities compared to those of the first type of communication device is thereby made capable of being served by the node.

摘要： In one or more aspects, the method and apparatus presented herein consider corresponding uplink resource allocations when allocating ARQ signal powers. In particular, in at least one embodiment, more power is allocated to the acknowledgment ("ack") signal(s) corresponding to user equipment (UE) transmissions that involve larger allocations of uplink resources. For the example context of an LTE network, an eNodeB "boosts" its ack signaling power for acknowledging UE transmissions associated with larger uplink bandwidth allocations. Additionally, or alternatively, the UE is configured to bias its ARQ signal evaluations, to bias its ack/nack decision determinations to favor the ack decision, at least for those acks associat
