摘要:
Techniques are described for wireless communication. A first method includes measuring, by a first device, a condition of a wireless channel; and generating at least one channel side information feedback message based on the measured condition of the wireless channel. The at least one channel side information feedback message provides information on a relationship of a set of parameters, including a data rate parameter, an error probability parameter, and at least one of a deadline parameter or a transmission link parameter. A second method includes measuring, by a first device, interference on a wireless channel; identifying an interfering device for the wireless channel based on the measurement; and generating a channel side information feedback message based on the measured interference on the wireless channel. The channel side information feedback message indicates the interfering device for the wireless channel and a correlation of interference from the interfering device with time or frequency.

Apparatuses and methods for performing asynchronous multicarrier communications are provided. One such method involves generating, at a first wireless device, a waveform including one or more carriers, shaping the waveform to reduce interference between the waveform and adjacent waveforms, and transmitting, on a spectrum, the shaped waveform asynchronously.

Aspects of the present disclosure provide for the pairing of two or more inter-band time division duplex (TDD) carriers. In some examples disclosed herein, a conjugate or inverse carrier may be used such that full duplex, or a close approximation thereto, is achieved. With the introduction of a paired channel and fast control channels, rapid uplink/downlink switching may be achieved for TDD carriers efficiently and effectively. Other aspects, embodiments, and features are also claimed and described.

Aspects of the present disclosure provide for the pairing of an inter-band carrier with a time division duplex (TDD) carrier. If the paired band is a frequency division duplex (FDD) band, then base stations and mobile devices may transmit and receive additional thin control channels on FDD carriers to enable full duplex operations. If the paired band is a TDD band, then a conjugate or inverse carrier may be used such that full duplex, or a close approximation thereto, is achieved. With the introduction of a paired channel and fast control channels, rapid uplink/downlink switching may be achieved for TDD carriers efficiently and effectively. Other aspects, embodiments, and features are also claimed and described.
摘要:
Aspects of the present disclosure provide a subframe structure for time division duplex (TDD) carriers that can be entirely self-contained. That is, information transmitted on a TDD carrier may be grouped into subframes, where each subframe provides communication in both directions (e.g., uplink and downlink) in a suitable fashion to enable such communication without needing any further information in another subframe. For example, a single subframe may include scheduling information, data information corresponding to the scheduling information, and acknowledgment information corresponding to the data information.

Methods, systems, and devices for wireless communications are described in which multiple operators may perform spectrum sharing using shared radio units (RUs), where the multiple different operators can access a same RU for communications with a user equipment (UE). A shared RU may receive requests for resources from two or more network nodes of two or more different network operators, for wireless resources in a first time period. The RU may determine a first resource allocation for the first time period based on different priorities of the different network operators. A first network operator may have a higher priority than a second or third network operator, and resources may be allocated to the first network operator ahead of the second or third network operators. The RU may transmit the first resource allocation to each of the different network nodes that transmitted requests for resources.
摘要:
Systems and techniques are disclosed to enhance the efficiency of available bandwidth between UEs and base stations. A UE transmits a sounding reference signal (SRS) to the base station. The base station characterizes the uplink channel based on the SRS received and, using reciprocity, applies the channel characterization for the downlink channel. As part of applying the channel information, the base station forms the beam to the UE based on the uplink channel information obtained from the SRS. The UE may include an array of antennas, each UE transmitting a different SRS that the base station receives and uses to characterize the downlink. Multiple UEs (or a single UE with multiple antennas) transmit SRS at the same time and frequency allocation (non-orthogonal), but with each sending its own unique SRS. Further, multiple UEs (or a single UE with multiple antennas) may send their SRS at unique time/frequency allocations (orthogonal).

摘要:
Aspects of the disclosure provide for a thin control channel structure that can be utilized to enable multiplexing of two or more data transmission formats. For example, a thin control channel may carry information that enables ongoing transmissions utilizing a first, relatively long transmission time interval (TTI) to be punctured, and during the punctured portion of the long TTI, a transmission utilizing a second, relatively short TTI may be inserted. This puncturing is enabled by virtue of a thin channel structure wherein a control channel can carry scheduling information, grants, etc., informing receiving devices of the puncturing that is occurring or will occur. Furthermore, the thin control channel can be utilized to carry other control information, not being limited to puncturing information. Other aspects, embodiments, and features are also claimed and described.

A method, an apparatus, and a computer program product for wireless communication are provided. The apparatus receives a discovery signal transmitted from a connection point (CP) via a directional beam. The discovery signal may include first information (including beam sweep configuration information) related to the CP. The apparatus then transmits an association signal to the CP based on the beam sweep configuration information and monitors for a resource grant from the CP based on the transmitted association signal. Alternatively, the apparatus transmits a discovery signal via a directional beam to a user equipment (UE). The discovery signal may include first information (including beam sweep configuration information) related to the apparatus. The apparatus then receives an association signal from the UE based on the beam sweep configuration information and determines a resource grant for communicating with the UE based on the received association signal.
