20130034092 | Joint Channel Detection of Out of Synchronization Condition - To test whether a first radio channel is synchronized, a first quality value (e.g., power control bits) is determined for a first radio channel (e.g., DPCCH or F-DPCH), and a second quality value is determined for a second radio channel (e.g., PCICH) which carries precoding information (e.g., beamforming weights); then the first and second quality values are combined. In specific embodiments the combining includes comparing the first and second quality values against respective first and second thresholds to obtain respective first and second binary results that are logically combined; or by multiplying the first and second quality values by respective first and second weighting values to achieve weighted values which are added. | 02-07-2013 |
20130115946 | TRANSMISSION OF CHANNEL QUALITY INDICATIONS - Indications of desired radio communications downlink characteristics are transmitted via a radio communications uplink from a user equipment to a node of a cellular wireless network, the indications each relating to one or more components of a radio communications link from the node to the user equipment. The indications are transmitted successively at different cycles, and at each different cycle a first parameter is determined, indicating a more preferred number of components and a second parameter is determined, indicating a less preferred number of components. First additional parameters are calculated and transmitted relating to the desired radio communications link quality corresponding to the first parameter and second additional parameters are calculated and transmitted relating to the desired radio communications link quality on the basis of the second parameter. The first and second parameters are each parameters which are variable between different cycles. | 05-09-2013 |
