| 20090083424 | Apparatus, methods, and computer program products providing a dynamic header structure for signaling resource allocations - In one non-limiting, exemplary embodiment, a method includes: receiving a message including a resource allocation map having a first portion and a second portion; utilizing the first portion to determine a specific mapping scheme of a plurality of mapping schemes, wherein the determined specific mapping scheme is used for the second portion; and obtaining, based on the determined specific mapping scheme, resource allocation information based on the second portion. In another non-limiting, exemplary embodiment, a method includes: generating a message including a resource allocation map having a first portion and a second portion, wherein the first portion is indicative of a specific mapping scheme of a plurality of mapping schemes that are applicable to the second portion; and transmitting the generated message. | 03-26-2009 |
| 20090268693 | Signaling part of semi-persistent configuration via downlink control channel - A method includes receiving a first control information from a network access node, the first control information comprising a plurality of fields defining control information elements that are relevant to a resource allocation; receiving a second control information from the network access node, the second control information comprising a plurality of fields defining control information elements that are relevant to the resource allocation; and declaring the resource allocation to be a persistent resource allocation if at least one of the plurality of fields of the second control information is the same as one of the plurality of fields of the first control information. Also disclosed are computer programs and apparatus for carrying out the method, as well as a network access node configured to compose first control information and second control information for expressing resource allocations. | 10-29-2009 |
| 20090318183 | METHOD, APPARATUS AND COMPUTER PROGRAM FOR DOWNLINK MU-MIMO POWER SETTINGS AND CONTROL - A set of J predetermined power level offsets that scale transmission power per user are stored in a local computer-readable memory. A set of N users to which are allocated overlapping downlink frequency resources are selected. From the stored set is then selected a power level offset. An indication of the selected power level offset is signaled to at least one of the N users; and the at least one of the N users are also sent a multiplexed transmission using the selected power level offset. N is an integer at least equal to two, J is an integer at least equal to two, and at least one member of the set is other than 1/n in which n is any positive integer less than N | 12-24-2009 |
| 20100027481 | Common resource signaling for multiple types of allocations - The exemplary embodiments of this invention provide a multi-stage approach, where, for example, one number can signal a first type of resource allocation (e.g., a consecutive allocation) or a second type of resource allocation (e.g., a best-M allocation based on best-M channel quality information). In one exemplary embodiment, a method includes: allocating a plurality of resource blocks to obtain a resource allocation; and signaling the resource allocation using an n-bit number, where the n-bit number expresses a value from an overall range of values having a first range of values and a second range of values, where a value within the first range of values specifies a first type of resource allocation and where a value within the second range of values specifies a second type of resource allocation, where the first type of resource allocation is different from the second type of resource allocation. | 02-04-2010 |
| 20110038331 | Control Channel Transmission With Component Carrier Aggregation - In accordance with the exemplary embodiments of the invention there is at least a method, apparatus, and computer program configured to compose signaling to include a component carrier indicator in a content of a downlink control information only when a size of an original part of a downlink control information on a scheduling component carrier is larger than or equal to an individual size of any corresponding downlink control information on at least one cross-scheduled component carrier, and to transmit the composed signaling to at least one user equipment. | 02-17-2011 |
| 20110280193 | DOWNLINK CONTROL CHANNEL-TO-RESOURCE ELEMENT MAPPING - In accordance with an exemplary embodiment of the invention, one or more first channels and one or more second channels are stored in a linear buffer. More specifically, the one or more first channels are stored in a first primary region of the linear buffer, and the one or more second channels are stored in a second primary region of the linear buffer, where if the second primary region is not large enough to store all of the second channels, one or more excess second channels are stored in a secondary area of the linear buffer. | 11-17-2011 |
| 20130195019 | INITIAL ACCESS IN CELLS WITHOUT COMMON REFERENCE SIGNALS - 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. | 08-01-2013 |
| 20130242908 | FLEXIBLE EXTENSION OF AN INFORMATION BLOCK - Communication systems in which a fixed size information block is transmitted to one or multiple receivers, such as the long term evolution (LTE) of the 3rd Generation Partnership Projection (3GPP), may benefit from a structure, in which a downlink control information (DCI) format, or more generally the fixed sized information block, can be extended by a small number of bits and still be backwards compatible with older terminals, which do not need the extra bits or may not even be aware of this extension. A method for providing this extension can include preparing a first codeword for transmission. The method can also include preparing a second codeword for transmission. The second codeword can have a code rate that is configured to be less than the code rate of the first codeword. The method can further include initiating simultaneous transmission of the first codeword and the second codeword. | 09-19-2013 |
