Abstract:
Aspects of the present disclosure provide a time division duplex (TDD) subframe structure that supports both single and multiple interlace modes of operation. In a single interlace mode, control information, data information corresponding to the control information and acknowledgement information corresponding to the data information are included in a single subframe. In a multiple interlace mode, at least one of the control information, the data information corresponding to the control information or the acknowledgement information corresponding to the data information is included in a different subframe. Both single and multiple interlace modes can be multiplexed together within the TDD subframe structure.
Abstract:
Techniques are described that provide for resource block (RB) alignment in mixed numerology wireless communications, in which a number of RBs for a particular numerology may occupy less than an entire system bandwidth. A fractional bandwidth may be identified as a difference between the bandwidth of the integer number of RBs and the system bandwidth and may be used to transmit information using one or more fractional RBs that may have a same or different numerology as the integer number of RBs. In some examples a placement scheme may be selected for placing the integer number of RBs, one or more fractional RBs, and/or one or more guard bands, within the system bandwidth. Numbering schemes for transmitted RBs and placement schemes may be signaled or may be implicitly determined based on one or more numerologies of the transmitted RBs or transmitted fractional RBs.
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:
Systems and method of embodiments herein operate to conserve battery power of user equipment (UE). Embodiments determine whether waking up a UE receiver would be beneficial and based on the determination, the UE either wakes up the receiver or returns to sleep. Embodiments determine whether to wake up the receiver by performing pre-wake up (PWU) operation which either wakes up the receiver in a low power mode or wakes up the UE's wake up receiver. It may be determined whether a wake up (WU) signal is received during a PWU stage. If a WU signal is received during the PWU stage the UE may perform a full wake up of the receiver. If a WU signal is not received the UE may return to idle mode. In embodiments, WU (Wake Up) DRX cycles are supplemented with a Full DRX (Discontinuous Reception) cycle.
Abstract:
Aspects of the disclosure provide a slot structure (e.g., the arrangement of channels and pilot signals within a slot) that can relax the processing timeline for a wireless communication device. For example, in the first or initial symbol of a slot, control information may be frequency division multiplexed (FDM) with a demodulation reference signal (DMRS) or with user data. In some cases, delayed-processing data may be sampled, and the samples may be buffered at the receiving device, for processing later, after control information needed to process the data has been received and processed. Further aspects provide for payload pre-tapering. That is, when a device delays the processing of data bits, this can cause a processing bottleneck after that buffering delay. By virtue of various pre-tapering techniques described herein, the processing load needed to process the delayed-processing data can be reduced. Other aspects, embodiments, and features are also claimed and described.
Abstract:
Some aspects of the disclosure provide for a flexible and reconfigurable subframe structure that allows various devices with different capabilities and frequency agility to efficiently utilize the available channel bandwidth (BW) and/or save power. In some aspects of the disclosure, the reference signal and/or control channel placement in the subframe can facilitate faster processing and increased sleep mode duration of the devices.
Abstract:
Methods, systems, and devices for wireless communication are described. A base station may select a two sets of reference signal resource elements (REs) for a symbol period, where each RE of the first set is contiguous to an RE of the second set. The base station may also identify resource element groups (REGs) for control signaling, where each REG covers one or more resource blocks (RBs). The base station may then perform interference cancellation, which may be based on an interference covariance matrix for each of the REGs. In some cases, the base station may coordinate with neighboring base stations (directly or through the core network) to ensure that the selected REGs do not partially overlap with reference signal transmissions or REGs of neighboring base stations.
Abstract:
Systems, methods, apparatuses, and computer-program products for performing dynamic bandwidth switching between control signals and data signals of differing bandwidths are disclosed. Frame formats are disclosed in which control signals are transmitted at different bandwidths than data signals. Receiver architectures for receiving the signaling formats are disclosed. A receiver can receive a relatively narrowband control signal while consuming a relatively low power and then dynamically adjust characteristics of various components to receive a data signal at a higher bandwidth while consuming a relatively higher power.
