Abstract: Systems, methods, apparatuses, and computer-readable storage media for managing power consumption of a mobile device are disclosed. The systems, method, apparatus, and computer-readable storage medium may cause the base station to identify an energy metric associated with a mobile device, and to configure the transmission between the base station and the mobile device based at least in part on the energy metric. The configuration of the transmission may reduce the power consumption of the mobile device for processing the transmission.

Abstract: 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.

Abstract: Methods, systems, and devices for outputting of codeword bits for transmission prior to loading all input bits. An example encoder may have multiple encoding branches. The encoder may divide the encoding branches into first and second encoding branch subsets, outputs of the first encoding branch subset being independent of inputs to the second encoding branch subset. The encoder may generate first and second subsets of output bits of a codeword in first and second encoding operations, the generating comprising inputting information bits of an information bit-vector and at least one frozen bit into respective encoding branches of the plurality of encoding branches and generating the first subset of output bits using the first encoding branch subset prior to generating the second subset of output bits using the second encoding branch subset. The encoder may output the first subset of output bits prior to outputting the second subset of output bits.

Abstract: The disclosure relates in some aspects to techniques for improved channel estimation. For example, a device can specify a pilot structure where pilot density differs over time. As another example, a device can indicate that a pilot from a prior transmission time interval (TTI) can be used for channel estimation. As another example, a device can employ frequency domain physical resource block (PRB) bundling with the bundling information signaling. As yet another example, a device can use an adjustable traffic-to-pilot ratio (TPR) for throughput optimization. Other aspects, embodiments, and features are also discussed and claimed.

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: Methods, systems, and devices for wireless communication are described. Some wireless communications systems (e.g., New Radio (NR) systems) may support the dynamic configuration of time intervals (or slots) for communication in a specific link direction (e.g., uplink, downlink, sidelink, etc.). In such cases, a base station may dynamically allocate time intervals (or slots) for broadcast or multicast data (e.g., via a physical downlink control channel (PDCCH)) based on the dynamically determined configuration of certain time intervals (or slots). The dynamic allocation of resources for broadcast or multicast data may ensure that broadcast or multicast data is not scheduled to be transmitted during time intervals configured for uplink communication. In some cases, the broadcast or multicast data may be transmitted on a portion of a system bandwidth that is frequency division multiplexed with another portion of the system bandwidth allocated for mobile broadband (MBB) communications.

Abstract: Various aspects of the present disclosure provide for enabling at least one opportunity to transmit mission critical (MiCr) data and at least one opportunity to receive MiCr data in a time division duplex (TDD) subframe during a single transmission time interval (TTI). The single TTI may be no greater than 500 microseconds. The TDD subframe may be a downlink (DL)-centric TDD subframe or an uplink (UL)-centric TDD subframe. How much of the TDD subframe is configured for the at least one opportunity to transmit the MiCr data and how much of the TDD subframe is configured for the at least one opportunity to receive the MiCr data may be adjusted based on one or more characteristics of the MiCr data. The MiCr data may have a low latency requirement, a high priority requirement, and/or a high reliability requirement. Various other aspects are provided throughout the present disclosure.

Abstract: Adaptive pilot signaling is disclosed in which resources allocated to pilot symbols are allowed to vary to more closely match channel conditions. User equipments (UEs) may request different pilot configurations depending on channel conditions. In one embodiment, a method includes receiving a first set of pilot symbols using a first number of resource elements during a first transmission time interval (TTI), and receiving a second set of pilot symbols using a second number of resource elements during a second TTI. In the embodiment, the first TTI and the second TTI include the same number of resource elements, and the first number of resource elements is different than the second number of resource elements.

Abstract: Wireless communications systems and methods related to the reduction in a probability of collision for grant-less transmissions from internet of everything (IOE) 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: Methods, apparatus, and systems for wireless communication are provided. A method for wireless communication includes configuring a first device for a first mode of communication, receiving wide area network (WAN) scheduling information from downlink signals received from a network entity when a radio air interface of the first device is configured for the first mode of communication, configuring the first device for a second mode of communication, determining a mesh network schedule based on the WAN scheduling information, and communicating wirelessly with a second device in accordance with the mesh network schedule when the radio air interface is configured for the second mode of communication. The first device and the second device may communicate at power levels below a power level threshold selected to cause the network entity to ignore transmissions between the first device and the second device.
