20090046650 | Resource scheduling enabling partially-constrained retransmission - The exemplary embodiments of the invention utilize techniques that provide an amount of scheduling flexibility for retransmissions (e.g., downlink HARQ retransmissions) while also limiting the amount of time within which a UE can expect retransmissions. Thus, the network retains scheduling flexibility while the UE can still operate in DRX, for example. In one exemplary embodiment, a method includes: receiving an initial transmission of information; and receiving a retransmission of the information, where the retransmission is received within a window of time having a predetermined duration, where the window of time is arranged to begin at a predetermined time or after a predetermined time interval. In further exemplary embodiments, the predetermined duration of the window of time is measured using a DRX retransmission timer and/or the predetermined time or the predetermined time interval is measured using a HARQ RTT timer. | 02-19-2009 |
20090125363 | Method, apparatus and computer program for employing a frame structure in wireless communication - A frame structure for scheduling radio resources includes a first time slot, followed by a plurality of other time slots each having either a second length, or a first length that is approximately double the second length. Transmissions are sent in downlink ones of the other time slots and received in uplink ones of the other timeslots. In various embodiments, the first length is 1.35 ms/19 symbols and the second length is 0.675 ms/9 symbols; the first timeslot is downlink and has length 0.852 ms/12 symbols; there is an additional guard period of 26 microseconds between the first timeslot and the other timeslot that follows the first timeslot which is uplink and has the first length; there may also be a single symbol between the guard period and that uplink timeslot for uplink signaling; and all other timeslots that are downlink are of the second length. | 05-14-2009 |
20090175232 | Joint Coding of Multiple TTI Information and Quality Indication Requests - A method includes storing in a memory a mapping of bit sequences to uplink resources, wherein a first one of the bit sequences indicates an uplink resource and requests a measurement report and a second one of the bit sequences indicates at least two uplink resources; assembling a selected one of the bit sequences with a resource allocation to be sent in a subframe that comprises more uplink resources than downlink resources; and receiving a response to the resource allocation in the uplink resource to which the selected bit sequence maps. In particular embodiments, the bit sequences are either 2 or 3 bits; one maps to a next available uplink resource and another maps to a second next available uplink resource. Apparatus and software are also described for both a network element and a user equipment. | 07-09-2009 |
20090257356 | Enhanced channel quality indication reports - A method includes making measurements of a received channel, and transmitting a channel quality report that includes at least one resource block-specific report indicative of a value of a channel quality metric over a bandwidth x, and that further includes an additional report indicative of the value of the channel quality metric over a bandwidth y, where y is greater than x. The channel quality metric may be a signal to interference plus noise ratio (SINR), and the additional channel quality report may be indicative of a difference between a mean value of the SINR of physical resource blocks found by a user equipment to exceed a reporting threshold and a mean value of the SINR over the measurement bandwidth y. | 10-15-2009 |
20090323613 | Selecting between normal and virtual dual layer ACK/NACK - An allocation of downlink resources is received, which are monitored on I layers for data. A resource-specific bit (ACK/NACK) is generated for each of those resources. From a pattern of those resources is selected an algorithm from among a first algorithm that bundles them in a first mode and a second algorithm that bundles them in a second mode. The selected algorithm is used on the generated resource-specific bits that correspond to the downlink resources, bundled according to the selected mode, to generate I reply bits which are then transmitted. At the network side a NACK reply bit is received, based on a pattern of the allocated downlink resources, a first algorithm that bundles them in a first mode or a second algorithm that bundles them in a second mode is selected. A bundling window and layer combination are determined from the selected algorithm, which gives the resource for retransmitting the NACK'd data. | 12-31-2009 |

20110312359 | Energy Savings For Multi-Point Transmission Wireless Network - The operational mode of individual ones of a plurality of geographically distributed network nodes is dynamically changed in correspondence with geographic location of at least one wireless data user. Wireless data service is adaptively provided to the at least one data user via at least one of the network nodes whose operational mode is dynamically changed also in correspondence with a data throughput requirement of the at least one data user. The operational mode changes may be switching between an operational diversity transceiving mode, an operational stand-alone transceiving mode, and an idle or off mode. The network nodes may be remote antennas or radio heads. In this manner the operational modes can be switched based on needs and locations of high data throughput users in a cell, and every node that is idle/off represents a power savings. | 12-22-2011 |
20110312363 | Optimizing Control Channel Performance With Virtual Inter-Cell Coordination - Channel conditions within each of N contiguous cells is determined. Based on at least the determined N channel conditions, there is determined a set of the N cells which are to utilize joint scheduling, and resources for a control channel are jointly assigning to individual cells of the set of cells. In various embodiments, the channel conditions are SINR and load on the control channel; and the set of cells is decided based on potential for mutual interference and/or potential that the control channel will not be filled. The resource may be jointly assigned based on user priority, so that serially for each highest priority user resources are assigned, the assigned resources are then blocked from compiled lists of radio resources, the highest priority user is removed and a next highest priority user is then the highest priority user to continue in the serial iteration. | 12-22-2011 |
