摘要:
Methods, apparatuses, and computer program products are disclosed for facilitating decoding a communication received from a wireless terminal. Encoded bits are received from the wireless terminal via a shared uplink channel, and a plurality of acknowledgment tones are identified within the encoded bits. A correlation value is ascertained corresponding to a correlation between detected bits within the plurality of acknowledgment tones and valid bits corresponding to any of a plurality of valid acknowledgment codewords. A determination is then made as to whether the plurality of acknowledgment tones includes information corresponding to a discontinuous transmission by comparing the correlation value to a threshold value.

Certain aspects of the present disclosure propose techniques for avoiding a disruption in synchronous hybrid automatic repeat request operation at system time rollover. The techniques define the behavior of a system before and after the system frame number (SFN) rollover point to ensure a known relationship between a hybrid automatic repeat request (HARQ) process identification number and system time.

A method, an apparatus, and a computer program product for wireless communication are provided in which one or more semi-static parameters associated with at least one neighboring eNode B (eNB) and an interfering user equipment (UE) are detected, at an eNB, and a blind interference reduction scheme based on the one or more detected semi-static parameters to reduce a signal from the interfering UE is applied.

The concept-structured image search technique described herein pertains to a technique for enabling a user to indicate their semantic intention and then retrieve and rank images from a database or other image set according to this intention. The concept-structured image search technique described herein includes a new interface for image search. With this interface, a user can freely type several key textual words in arbitrary positions on a blank image, and also describe a region for each keyword that indicates its influence scope, which is called concept structure herein. The concept-structured image search technique will return and rank images that are in accordance with the concept structure indicated by the user. One embodiment of the technique can be used to create a synthesized image without actually using the synthesized image to perform a search of an image set.

Techniques for sending control information in a wireless communication system are described. In an aspect, a user equipment (UE) may send data for control information in a resource block with frequency division multiplexing (FDM) and may send pilot in the resource block with frequency-domain code division multiplexing (CDM). The UE may determine multiple groups of subcarriers to use to send data in multiple symbol periods of the resource block based on a predetermined pattern or a pseudo-random hopping pattern. Each group may include consecutive subcarriers to support localized FDM. The multiple groups may include different subcarriers to provide frequency diversity and possibly interference averaging. The UE may send modulation symbols for data (e.g., in the time domain) on the multiple groups of subcarriers in the multiple symbol periods. The UE may send a reference signal sequence for pilot on multiple subcarriers in each symbol period for pilot.

Antennas for electronic devices such as portable computers are provided. An antenna may have a dipole structure in which one antenna element serves as a matching element and another antenna element serves as a radiating element. The antenna elements may be mounted on a substrate. The substrate may be mounted on a support structure that is attached to a grounding plate. The grounding plate may be grounded to a conductive housing portion of a portable computer. The antenna may be mounted within the conductive housing in the vicinity of an opening in the housing. The opening may be a slot opening that is used to accommodate optical disks or other storage media. Radio-frequency signals for the antenna may pass through the opening.

An electronic device may be provided with a conductive housing. The conductive housing may be formed from a metal. Slots may be formed in the housing. The slots may serve as an antenna and may be fed using an antenna feed structure within the electronic device housing. The electronic device may have a frame to which housing structures are attached and may have a stand or other support structure. The frame may be used to mount a display, to support housing walls, to support clutch barrel structures, etc. The slots may be formed in the frame or in a space between the frame and the housing walls. The slots or other antenna structures may also be formed in the stand. Multiple slots may be used together to support operations in two or more communications bands. There may be multiple dual slot antennas in the electronic device.
摘要:
In an aspect, a method assists with blind decoding of uplink control signals on a Physical Uplink Shared Channel (PUSCH) and Physical Uplink Control Channel (PUCCH). The method assists in determining the uplink control path in the event a user equipment (UE) misses an uplink grant and blind decoding occurs. It is determined whether an uplink acknowledgement, rank indicator, and/or channel quality indicator are found on a PUSCH. If not, it is determined whether a scheduling request is expected and whether special handling for the scheduling request is indicated. Depending on those determinations, and whether any decoding attempts for uplink signals are successful, either the PUSCH or PUCCH is selected as the uplink control path.

摘要:
A method of wireless communication includes configuring a virtual SRS (sounding reference signal) transmission to prompt a user equipment (UE) to use a shortened uplink transmission format to create a silent period at an end of a subframe. Reports are received from the UE indicating interference observed during the silent period.
