摘要： A method of scheduling wireless data transmissions between a mobile terminal and a base station using multiple system carrier signals is disclosed. The method comprises receiving (101) in the mobile terminal information from the base station indicating available system carriers and transmitting from the mobile terminal information indicating the terminal's capability to handle non-contiguous system carriers; detecting (102) at least one dynamic parameter indicative of the terminal's current capability to handle non-contiguous system carriers; determining (103) from the dynamic parameter whether a situation has occurred in which the terminal's capability to handle non-contiguous system carriers has changed; transmitting (104), in such case, a connection release request to the base station; and transmitting (105) a connection setup request and information indicating the terminal's changed capability to handle non-contiguous system carriers to the base station. Thus system carriers that can be handled by the terminal in the present situation can be allocated.

摘要： In a heterogeneous cell deployment a mobile terminal may need to receive control data transmissions from a macro node at the same time as a pico node is transmitting user data for the mobile terminal, using the same frequency or set of frequencies. This can result in a problematic interference situation. According to several embodiments of the present invention, at least one of two general approaches is used to mitigate the interference situation described above. In a first approach, the pico node's transmission power is reduced in some time intervals, thereby reducing the interference to a level where reception from the macro node is possible. In a second approach, which may be combined with the first approach in some cases, the data transmitted from the macro node is provided by the pico node, either alone or in combination with the macro node.

摘要： A adaptive method implemented by a mobile station improves the likelihood of detecting control messages transmitted to the mobile station in band on a shared downlink traffic channel. When the mobile station expects a control message to be transmitted on the shared downlink traffic channel, the mobile station may adapt the receiver configuration and/or receiver parameters to reduce a likelihood of missed detection of control messages. In one embodiment, the mobile station is configured to adjust a correlation threshold used for said scheduled transmission detection to reduce the likelihood of a missed detection.

摘要： A cell searching procedure is modified to enable a user terminal to determine whether a detected signal originates in a known cell or a new cell having the same cell identifier as the known cell. When a signal is detected, the user terminal determines the cell identifier and timing of the detected signal. If the cell identifier matches a known cell and the timing is outside the timing window of the known cell, the user terminal compares detected signal with a corresponding received signal received from the known cell having the same cell identifier as the detected signal source. The user terminal determines, based on said comparison, whether the detected signal is from the known cell or a new cell.

摘要： The embodiments herein relate to a method in a relay node (110) for relaying data from a first network node (107) to a second network node (101) in a radio communication network (100). The relay node (110)receives the data from the first network node (107) and decodes the received data. The relay node (110) determines a delay constraint of the decoded data and recodes the decoded data. The relay node (110) relays the recoded data to the second network node (101) based on the determined delay constraint and according to a radio communication protocol. The communication between the relay node (110), the first network node (107) and the second network node (101) is based on the same radio communication protocol.

摘要： A method in a first radio communication node (110, 310, 710, 1010) and a first radio communication node (110, 310, 710, 1010) for scheduling a data transmission in a first time frame using one of a plurality of modulation and coding schemes are provided. The data transmission is to be transmitted between the first radio communication node (110, 310, 710, 1010) and a second radio communication node (120, 320, 720, 1020). The first radio communication node (110, 310, 710, 1010) obtains (301, 701, 1001, 1401) a first indication about channel quality for the first time frame. The first radio communication node (110, 310, 710, 1010) obtains (302, 702, 1002, 1402) second indication about a possible upcoming transmission failure. The possible upcoming transmission failure relates to a feedback information to be transmitted in a second time frame. The feedback information is associated with the data transmission in the first time frame. The first radio communication node (110, 310, 710, 1010) selects (303, 703, 1003, 1403) a modulation and coding scheme out of said plurality of modulation and coding schemes based on the first indication and the second indication. Next, the first radio communication node (110, 310, 710, 1010) schedules (304, 704, 1004, 1404) the data transmission using the selected modulation and coding scheme.

摘要： According to the teachings presented herein, a method and apparatus provide a reduced search space for blindly decoding a message included in a signal received at a communication receiver, where the message has an unknown format. Improving blind detection efficiency in this manner offers numerous advantages, including but not limited to lower power consumption through reduced processing overhead, and lower power consumption through expanded sleep opportunities. As a non-limiting example, the communication receiver comprises a mobile station configured for operation according to Long Term Evolution (LTE) standards, as promulgated by the 3GPP for E-UTRA systems, where the mobile station is configured to reduce a search space of DCI message decoding by determining message format likelihoods and blindly decoding a received DCI message based on the message format likelihoods.

摘要： For wireless networks that transmit synchronization signals allowing user equipment to synchronize to cells within the network and transmit reference signals allowing user equipment to determine cell identities, a method and apparatus taught herein advantageously link the synchronization signal sequences to the reference signal sequences according to a defined mapping. The linking simplifies the cell search process by allowing user equipment to determine cell identities based on mapping detected synchronization signal sequences to the corresponding reference signal or to the corresponding subset of reference signals in embodiments where there are more reference signal sequences than synchronization signal sequences. In at least one embodiment, the network is a 3G LTE network and at least the Primary Synchronization Signal (P-SyS) sequences are linked to the Downlink (DL) reference symbol sequences according to a defined mapping, thereby allowing to user equipment to determine cell identities from detected P-SyS sequences.
