20110222456 | DIVERSITY INDICATING METHOD IN GERAN/MUROS SYSTEMS - A diversity indication method in GERAN/MUROS system, includes the steps: after a user receives a diversity indication, it receives data from two sub-channels, and then carries out diversity combination; if the user does not receive diversity indications, users receive data from subchannel allocated to them. Using the method of this invention, we can carry out diversity indications in GERAN/MUROS system. In this way, users do not need to determine whether current frame is using diversity transmission in all sub-channels by carrying out autocorrelated operations over training sequences 26 bit long in each frame, and the users may demodulate information from another paired subchannel only when they receive diversity indications in subchannel allocated regularly to greatly reduce the user's complexity. | 09-15-2011 |
20120155356 | METHOD FOR ENHANCING SACCH PERFORMANCE - A method for enhancing Slow Associated Control CHannel (SACCH) performance, which includes steps of: if a user that uses a half-rate Traffic CHannel (TCH) is contained in a coupled user group, a base station instructing the user on an Adaptive Multi-user channels on One Slot VAMOS sub-channel to use a half-rate sub-channel | 06-21-2012 |
20140153535 | HARQ TIMING SCHEME FOR SIGNLE-CARRIER UPLINK CONTROL INFORMATION WITH INTER-SITE CARRIER AGGREGATION - There is a pattern for downlink almost blank sub frames ABSFs for a first network node (e.g., macro eNB) operating in a first component carrier (e.g., PCell). For a user equipment UE operating with the first network node on the first component carrier and also with a second network node on the second component carrier, then either or both of the following are imposed. The UE is scheduled on the first component carrier such that no uplinic control information UCI from the UE is scheduled for any uplink subframe in the first component carrier which maps from any of the ABSFs; and the UE is scheduled on the second component carrier such that UCI from the UE is scheduled only for an uplinic subframe in the second component carrier which maps from any of the ABSFs. By example, the UCI includes either/or ACKs and NACKs corresponding to data sent downlink to the UE. | 06-05-2014 |
20140185576 | PDSCH ASSIGNMENT INDICATION FOR FDD SCELL ACK/NACK TRANSMISSION - A pico network node sends to a UE an allocation of physical downlink shared channel PDSCH subframes on the SCell. The allocation has control signaling indicating a number of the allocated PDSCH subframes that lie within a multiplexing window. The pico network node sends to the UE data on each of the allocated downlink subframes. The UE is also configured for a PCell with a macro network node not co-located with the pico. The UE determines from control signaling the number of PDSCH subframes that are allocated; and checks the determined number against PDSCH subframes it's received, to detect whether any allocated PDSCH subframe is missed. In an embodiment the control signaling is two bits per allocated downlink subframe as an assignment indication. | 07-03-2014 |
20140287693 | SPECTRUM SENSING - Provided are methods, corresponding apparatuses, and computer program products for performing spectrum sensing on a spectrum. A method comprises receiving, at a user equipment, information regarding performing spectrum sensing from a base station; performing, based upon the information, the spectrum sensing by the user equipment in an idle mode; and transmitting, by the user equipment out of the idle mode, to the base station a result of the spectrum sensing. With the claimed inventions, transmission interruption caused by non-idle user equipments performing the spectrum sensing would be eliminated. | 09-25-2014 |
20140362798 | SHIFTING HARQ FEEDBACK FOR COGNITIVE-RADIO-BASED TD-LTE SYSTEMS - A method includes, in response to a determination one or more quiet periods conflict with specified hybrid automatic repeat request feedback timing, sending one or more indicators to one or more user equipment to indicate to the user equipment to shift the specified hybrid automatic repeat request feedback timing to a shifted hybrid automatic repeat request feedback timing. The method includes communicating hybrid automatic repeat request feedback based on the shifted hybrid automatic repeat request feed-back timing. Another method includes receiving at a user equipment one or more indicators indicating to the user equipment to shift specified hybrid automatic repeat request feedback timing to a shifted hybrid automatic repeat request timing, and communicating hybrid automatic repeat request feedback based on the shifted hybrid automatic repeat request timing. Apparatus, computer program product, and computer programs are also disclosed. | 12-11-2014 |
20150055523 | UL-DL INTERFERENCE MANAGEMENT FOR TDD eIMTA - Uplink-downlink (UL-DL) interference management may benefit various communication systems, such as communication systems of the third generation partnership project (3GPP) long term evolution advanced (LTE-Advanced) release 12 (Rel-12). More specifically, certain methods and apparatuses may provide LTE time division duplex (TDD) enhancement for DL-UL Interference Management and Traffic Adaptation (TDD eIMTA). A method can include determining whether to activate or deactivate TDD eIMTA, or other dynamic TDD, in a cell. The method can also include informing at least one neighbor cell regarding a decision to activate or deactivate TDD eIMTA or other dynamic TDD. | 02-26-2015 |
20150103775 | FLEXIBLE HARQ ACK/NACK TRANSMISSION - A method including utilizing HARQ process grouping and subframe grouping to carry ACK/NACK transmissions, wherein the HARQ process grouping divides HARQ processes into one or more groups, and the subframe grouping divides a radio frame into one or more groups. The method may further include carrying ACK/NACK transmissions. | 04-16-2015 |
