Abstract: A transmitter may allocate resources across multiple links for a transmission to a receiver. The transmitter may transmit a resource grant to the receiver. The transmission may include a data packet allocated across multiple links, and pilot signals on a number of links. The receiver may use an indicator included with the resource grant to trigger measurement of channel quality for links with pilot signals.

Abstract: Techniques are described for wireless communication. A first method includes wirelessly communicating at a first device, with a second device, according to a first subframe structure; receiving a subframe truncation parameter from the second device; and terminating the first subframe structure based at least in part on the subframe truncation parameter. The first subframe structure includes a first periodic sequence of downlink transmission time intervals (TTIs) and uplink TTIs. A second method includes wirelessly communicating at a first device, with a second device, according to a parameterized self-contained subframe structure having an interlaced portion and a tail portion; and reducing a delay indicated by a nominal trigger-response delay parameter associated with a downlink TTI, to enable a response message corresponding to the downlink TTI to be transmitted during the tail portion and before termination of the subframe structure.

Abstract: Wireless communications systems and methods related to the reduction in a probability of collision for grant-less transmissions from internet of everything (JOE) devices while not increasing search complexity at a base station are disclosed. An IOE device randomly selects a first access resource from a common pool, that the base station searches, to initiate a transmission. If a metric associated with the data transmission is predicted to exceed a threshold, the IOE device also randomly selects a second access resource from a collision reduction pool that the base station does not search. The IOE device notifies the base station, in the data transmission, to switch to the second access resource after a fixed period to the selected second access resource that is included in the data transmission. After the specified period, the base station and the IOE device switch to the second access resource and complete the data transmission.

Abstract: Systems and techniques are disclosed to enhance the efficiency of available bandwidth between UEs and base stations. A UE transmits a sounding reference signal to the base station, which characterizes the uplink channel based on the SRS received and, using reciprocity, applies the channel characterization for the downlink channel. The base station may form the beam to the UE based on the uplink channel information obtained from the SRS. As the downlink channel changes the base station needs updated information to maintain its beamforming, meaning it needs a new SRS. Transmission of the SRS takes resources; to minimize this, the UE or the base station can determine a period during which the downlink channel will predictably remain coherent and set up a schedule for sending SRS. Alternatively, the UE or the base station can determine on demand that the channel is losing coherence and initiate an on demand SRS.

Abstract: 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.

Abstract: Techniques for efficiently decoding data at a receiver are disclosed. In one aspect, total available decoding time of the receiver is initially allocated to a plurality of code blocks of a plurality of transport blocks to obtain initial allocated decoding times for the plurality of code blocks. The initial allocated decoding time for each code block may be given by a particular number of decoding iterations to perform for that code block. One or more code blocks of one or more transport blocks are decoded. After decoding the one or more code blocks, a remaining available decoding time is determined and reallocated to undecoded code blocks of the plurality of transport blocks to obtain updated allocated decoding times for the undecoded code blocks. The remaining available decoding time may be reallocated across code blocks of a transport block, across transport blocks, across carriers, across radio access technologies, or a combination thereof.
