摘要:
An apparatus, method, system and computer program product provide control channel coordination in heterogeneous networks. Parameters are provided indicating the availability of resources, wherein a resource is defined as an available radio frequency per time interval, and parameters indicate configuration of a physical channel configured for downlink control, for a physical control channel configured for format indication, and for a physical channel configured for HARQ indication, for use in both of two different communication cells providing radio communication services for terminals located therein. Further, a first resource allocation set and a second resource allocation set are determined, wherein determinations of the first resource allocation set and the second resource allocation set are made to be as mutually disjoint in resource allocation as possible in consideration of the parameters.

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.

An apparatus is described which includes a transceiver configured to be connectable to a first network node by a first uplink connection and at least a second network node by a second uplink connection. Uplink control signalling is generated independently for each network node, wherein the generated uplink control signalling for the first network node is sent via the first uplink connection, and the generated uplink control signalling for the second network node is sent via the second uplink connection.

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.

A user equipment (UE) may receive an OFDM signal having control channel elements (CCEs). The CCEs may be arranged in levels where a first level aggregates less CCEs than a second level. A processor may search for a control channel from control channel candidates that is comprised of the CCEs. A limited number of CCEs may be searched on the first level.
摘要:
A user equipment (UE) receives a first dynamic resource allocation on a first channel (PDCCH), then sends data according to the first resource allocation. During a time at which an ACK/NACK for the sent data is scheduled to occur on a second channel (PHICH), the UE is engaging in an activity that takes priority over the ACK/NACK. The UE then receives a second dynamic resource allocation on the first channel and determines the ACK/NACK for the sent data from the second dynamic resource allocation. The determining can be direct, as in receiving a zero-valued resource allocation; or it may be indirect as in mapping the second dynamic resource allocation to the second channel and receiving the acknowledgement on the second channel after that mapping. Also detailed are similar mirror actions from the Node B's perspective, as well as apparatus, methods, and embodied computer programs.
