A method, apparatus and computer program product are provided in order to allow an uplink resource request to be transmitted to the access point even in an instance in which the mobile terminal is receiving a continuous downlink transmission and repeated ACK/NACK transmissions are enabled. In this regard, a method, apparatus and computer program product are provided to prioritize a preamble transmission for a random access procedure relative to the repeated ACK/NACK transmissions. The method, apparatus and computer program also prioritize at least one message of the random access procedure.

The specification and drawings present a new method, apparatus and software related product (e.g., a computer readable memory) for implementing enhanced and flexible radio aperiodic measurements, e.g., on an unlicensed band in LTE wireless systems and providing effective and timely reporting. A UE may receive from a wireless network an aperiodic measurement request to measure a special measurement object (e.g., a neighbor cell) specified in the aperiodic measurement request, e.g., in an unlicensed band. In response to the aperiodic measurement request, the UE may perform the measurement of the special management object until a further instruction from the wireless network or for a determined period of time. Inter-frequency measurements may be performed during the measurement gap determined from the aperiodic measurement request.

A radio frame or subframe is checked and it is determined to satisfy at least one predefined condition. In response to that determination, a second search space is utilized such that a number Y of blind detections for a user equipment UE in the determined radio frame/subframe is greater than a number X of blind detections for the UE in the radio frame/subframe if a first search space were utilized. In various embodiments the predefined condition is: the number X of blind detections is less than a threshold value Z (Z>=Y) where Z is a maximum number M of blind detections defined by a transmission mode for the frame's/subframe's component carrier CC; a number of CCs configured for the UE; the radio frame or subframe is in the first CC but not in the second CC one of uplink or a special subframe (further conditions) or an almost blank subframe.

Systems and techniques for managing the use of industrial-scientific-medical bands for cellular network communication. An apparatus comprises a processing system and a memory storing a set of program instructions. The processing system is configured to cause the apparatus to receive channel information from a UE reporting the control of an industrial-scientific-medical (ISM) band channel by the UE and cause the apparatus to schedule a communication session with the UE over the channel, with the channel being configured and activated as an ISM secondary component carrier (SCC). The apparatus may further request one or more user equipments (UEs) to report their wireless fidelity (WiFi) capability and request user equipments having WiFi capability to compete for the wireless medium and report occupation of the wireless medium in the form of a request to send command, to which the apparatus responds with a clear to send command.

An apparatus and a method is provided, by which a first type cell is controlled, wherein a plurality of second type cells are located in the same area as the first type cell, wherein control signal transmission to at least one user equipment is carried out via the first type cell and data transmission to the at least one user equipment is carried out via one of a plurality of the second type cells, and handover of data transmission of a user equipment from a source cell being one of the plurality of second type cells to a target cell being another one of the plurality of second type cells is controlled. Moreover, also an apparatus and a method of e.g., a user equipment are provided, by which a handover of data transmission from a source cell being one of the plurality of second type cells to a target cell being another one of the plurality of second type cells is performed, while maintaining control signal transmission with the first type cell.
摘要:
Apparatus, methods, and computer programs that selectively transmit one or more local area buffer status reports by a macro base station over a macro link or transmit a macro buffer status report by a local area access point over a local area link in a dual connection deployment scenario in response to a cross link buffer status report trigger. The apparatus, methods and computer programs may include several cross buffer status reporting triggers. The user equipment may trigger cross buffer status reporting in response or incidental to one or more measurement events. The user equipment may also trigger cross buffer status reporting in response to or incidental to a link failure. The user equipment may also trigger cross buffer status reporting in response to receiving a request from an eNB.
摘要:
A method for synchronizing channels on unlicensed bands is described. The method includes determining whether a SCC channel has started to be used by a first network. The SCC channel is a CA channel shared with at least one other network. In response to determining that the SCC channel has been started to be used by the first network, the UE determines an off duration describing a period since a previous SCC channel ON period. A given channel ON period is a continuous period of use of the given channel by the first network, The method also includes, in response to determining that the off duration is less than a minimum threshold duration, performing fine synchronization based on CRS tracking on the SCC channel using course synchronization parameters of the previous SCC channel ON period. Apparatus and computer readable media are also described.

A method is provided for configuration of a special subframe pattern configuration. The method may include determining a configuration of a primary special subframe pattern configuration. The first special subframe configuration may have a corresponding secondary special subframe pattern configuration for multiplexing with the primary special subframe pattern configuration. The method may further include, responsive to a downlink assignment following the configuration of the primary special subframe pattern configuration, using the secondary special subframe pattern configuration instead of the primary special subframe pattern configuration. A corresponding apparatus and computer program product are also provided.
