A method of sending information from a first base station to other base stations including sending information to a first plurality of the base stations at a first time; and sending said information to a different plurality of the base stations at a later time according to a predetermined sending pattern for timing sending of said information to different pluralities of the base stations at different times.

The present invention relates to methods and apparatuses for controlling cell configuration in a cellular network, wherein a cell identity and a local cell spectrum resource entity or profile are assigned to an access device in response to a result of sensing a local radio environment at said access device to detect possible neighbor cells. The assigned local cell spectrum resource entity or profile is used to allocate cell spectrum resource from a shared multi-operator spectrum to said access device.

Systems and methods for providing half duplex user equipment in a packet based radio frequency signaling communication system. User equipment with half duplex receiver and half duplex transmitter on IC providing a transceiver capability performs a cycle of receiving downlink messages for a predetermined number of sub frames, shifting to a transmit mode, transmitting uplink messages for the predetermined number of sub frames, shifting to a receive mode, and repeating the cycle of half duplex sub frames. A discontinuous reception function performs a DRX protocol wherein power is reduced to the transceiver for a period of time. A determination is made at the end of the discontinuous reception period to see if the half duplex cycle is at an uplink sub frame; if so, the end of the discontinuous reception is shifted by the user equipment to a downlink sub frame by adding a delay.

A network access node eNB sends to a user equipment UE a pattern of subframe measurement restrictions and an indication of how to utilize the pattern for measuring subframes. The indication may select from among: the UE's own-cell measurements; the UE's neighbor-cell measurements; both same and neighbor-cell measurements, and no measurement restrictions. The eNB may generate the pattern from an almost-blank subframe ABS pattern for the UE's own-cell and of its neighbor-cell. The pattern and indication may be sent in separate RRC messages, or if sent in one message there is a second indication sent in a second RRC message instructing the UE to terminate utilizing the pattern and indication for restricting its subframe measurements. Embodiments are particularly useful for inter-cell interference mitigation eICIC for the LTE-Advanced system.
摘要:
There is proposed a mechanism by means of which information can be generated and used for estimating and identifying at each base transceiver station of a communication network the set of other base transceiver stations generating interference on certain monitored component carriers used by the base transceiver station, i.e. information for the generation of the incoming uplink background interference matrix. For this purpose, a specific communication information set, referred to as uplink radio load map, is determined which informs about an average (time/frequency) and aggregated (over all or group of served UEs) uplink load measure per component carrier. Based on the uplink radio load map received via suitable signaling from other base transceiver stations, each base transceiver station can determine the incoming uplink background interference matrix and initiate, if necessary, suitable measures for reducing interference per component carrier.

An apparatus, method, system and computer program product is configured for avoiding base station self-interference due to transmit intermodulation in carrier aggregated communication systems. Physical downlink communication channels are allocated to respective component carriers per time interval according to a communication service in which communication is performed on an aggregation of component carriers of one or more frequency band such that component carriers to be used for transmission are separated from component carriers to be used for receiving by a transmit-receive-frequency gap band. However, not all available component carriers to be used for transmission are allocated in the same time interval. Rather, in each time interval, the physical downlink communication channels to be allocated for transmission are allocated to the available component carriers to be used for transmission such that, in each frequency band, the overall emission spectrum does not reach beyond the transmit-receive-frequency gap band.
