摘要:
Frequency resources for common control regions of a control channel are defined or determined as a function of at least bandwidth and an identifier of a specific cell. Communications between a wireless network and a mobile device are then done using the defined/determined frequency resources of the common control regions of the control channel. In the non-limiting embodiments: the bandwidth is bandwidth of a cell or of a component carrier; the frequency resources are defined/determined further as a function of an offset value; the common control regions are of an ePDCCH and the offset value differs from a channel edge offset value for common control regions of all other ePDCCHs of all other adjacent cells or all other transmit nodes in the same cell; and the frequency resources comprise frequency stripes (which may be interleaved by resource element groups) distributed in frequency across the bandwidth.

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.
摘要:
When resources reserved for the purpose of transmitting control information relating to transmissions between an access node and any one of a plurality of communication devices served by the access node are identified as resources that are not required for said purpose, transmitting via said resources a data sequence recognisable by each communication device served by said access node as not being control information for said respective communication device.
摘要:
Wireless channel interference information is determined (e.g., a background interference matrix BIM constructed from multiple user equipment measurements). Reliability of the interference information is classified and sent with the interference information to a neighbor network access node such as a HeNB. In various embodiments there are three layers of reliability, the above being the first. The second layer utilizes variability of a plurality of such reliability indications received from the same neighbor HeNB, which is updated as new interference information and reliability indications are received from that same neighbor HeNB. The third layer utilizes a peer review/update process on the neighbor HeNBs themselves, where each HeNB's performance is shared among all and updated by one another as different HeNBs utilize one another's BIM and assesses how reliably it reflected actual interference conditions. This addresses concerns for data/source reliability since communication interfaces among HeNB groups may not be controlled by a single network operator.
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.
摘要:
A method, apparatus, system, and computer program embodied on a computer readable medium is provided to define new messages to be transmitted over a broadcast channel to better support uncoordinated base station deployment in a local area environment. In this context, uncoordinated local base station deployment refers to cases where new base stations are placed, and activated, without any detailed a priori network planning and considerations for placement of already active base stations in the area.

There is provided a method including performing frequency domain acknowledgement/negative acknowledgement (ACK/NAK) bundling across component carriers within a user equipment reception bandwidth; generating a bundled ACK/NAK value corresponding to at least one code word on the basis of the performed ACK/NAK bundling; and including information relating to the generated bundled ACK/NAK value and the number of detected downlink grants within the user equipment reception bandwidth in an ACK/NAK resource to be transmitted on an uplink control channel.
摘要:
A method, system, apparatus, and computer program product for decoding control information, wherein a total number of allocation blocks defining control channels to be allocated to users for at least one of uplink and downlink directions is determined. Then, a format which determines resource allocation within allocation blocks is selected, allocation blocks are decoded using the selected format, and an error checking is performed for the decoded allocation blocks. This selecting, coding and error checking is repeated for different available formats until no error is revealed in said error checking. Thereby, a blind estimation of a format chosen for the control channel information can be achieved, so that additional amount of control signalling can be reduced.
