Abstract: Wireless communications systems may support user equipment (UE)-specific hybrid automatic repeat request (HARQ) timeline offsets such that transmission time intervals (TTIs) reserved for uplink HARQ transmissions are reserved on a per UE basis (e.g., TTIs are not reserved or designated on a network level or aligned across all or many UEs within the system). That is, UEs within a wireless communications system may employ a UE-specific offset for their respective HARQ timelines. UE-specific HARQ timeline offsets may be derived, by the UEs, explicitly or implicitly. Further, the network (e.g., a base station) may configure UE-specific HARQ timeline offsets to be distributed in time to avoid uplink HARQ transmission collisions between UEs, to eliminate the loss of TTIs for a second carrier operation (e.g., such as NR uplink) on a network wide basis, etc. The base station may then communicate with the UEs according to their corresponding UE-specific offset HARQ timelines.

Abstract: Systems, methods, apparatuses, and computer-program products for performing dynamic bandwidth switching between control signals and data signals of differing bandwidths are disclosed. A wireless communication apparatus comprises a memory and a processor coupled to the memory. The processor is configured to transmit a control signal to a user equipment (UE) using a first bandwidth. The processor is further configured to transmit a data signal to the UE using a second bandwidth wider than the first bandwidth. The control signal and the data signal are transmitted over a single carrier frequency. The control signal comprises an indication of a characteristic of the data signal. The data signal is transmitted after the control signal such that the data signal and control signal are separated by a time interval. The time interval is based on at least a switching latency of the UE.

Abstract: Methods, systems, and devices are described for wireless communication. In one method, a method of wireless communication at a user equipment (UE) includes receiving a synchronization signal. The synchronization signal may be common to a plurality of cells within a network. The method further includes acquiring a timing of the network based on the synchronization signal, and transmitting a pilot signal in response to acquiring the timing of the network. The pilot signal may identify the UE and be concurrently receivable by the plurality of cells within the network. Other aspects, features, and embodiments are also claimed and described.

Abstract: Control information may be identified and provided to a user equipment (UE) that is formatted into a codeword that is transmitted in a first symbol of a downlink transmission to the UE. The control information may include an allocation of downlink or uplink resources for the UE and data processing parameters. The control information may be partitioned into first control information transmitted in a first codeword and second control information that may be formatted into a second codeword. The second control information may be determined based at least in part on the data acknowledgment from the UE. Such partitioned control information may allow a base station to perform some processing related to transmissions for a transmission time interval (TTI) prior to the start of the TTI, and allow the base station to perform some processing for the TTI after the start of the TTI.

Abstract: Methods, systems, and devices for wireless communication are described. A wireless device may receive a downlink (DL) reception indication during an active duration of a discontinuous reception (DRX) configuration. The DL reception indication may indicate the presence of a reception opportunity following an inactivity interval, as well as the length of the inactivity interval. The wireless device may refrain from DL monitoring during the inactivity interval. In some cases, the wireless device may enter a sleep mode during the inactivity interval and wake up to receive a subsequent transmission during the reception opportunity. In some examples, the wireless device may use the inactivity interval to communicate using a different radio access technology (RAT).

Abstract: Systems and techniques are disclosed to reduce pilot overhead by providing common reference signals coded with cover codes that are orthogonal in time and frequency domains. Common reference signals that are coded by cover codes orthogonal in both domains can be de-spread in both the time and frequency domains for improved resolution and larger pull-in windows for both. Also disclosed is semi-uniform pilot spacing in both the frequency and time domains. In a time domain, a first pilot symbol pair is spaced by a first time interval from each other and a second pilot symbol pair is spaced by a second time interval from the first pair, the second interval being greater than the first. In a frequency domain, a first set of pilot symbols is densely placed in a selected frequency band and a second set of pilot symbols is sparsely placed surrounding and including the selected frequency band.

Abstract: Conditional progressive encoding and decoding is discussed, in which a receiver receives a plurality of encoded message segments as a sequence of messages, and sequentially decodes each of the message segments in sequence, in which the decoding of the next encoded message segment is triggered only by successfully decoding the current encoded message segment. On the transmitter side, the transmitter breaks a message payload into a sequence of message segments, and then independently processes each message segment for generating error detection coding and encoding into multiple codeword segments. The transmitter multiplexes each codeword segment over the spectral space of subcarriers to transmit the message.

Abstract: Aspects of the present disclosure provide a scheduling entity for facilitating Multiple Input Multiple Output (MIMO) wireless communication by dynamically assigning ranks to scheduled entities for each sub-band of a slot. In some examples, the rank assigned to a particular scheduled entity may be increased or decreased between sub-bands of the slot based on the amount of scheduled user data traffic for that particular scheduled entity relative to the amount of scheduled user data traffic for other scheduled entities. The scheduling entity further schedules resources within the sub-bands of the slot based on the assigned ranks and transmits an enhanced control channel providing scheduling information indicating the scheduled resources to the scheduled entities.

Abstract: In an aspect of the disclosure, a method, a computer program product, and an apparatus are provided. The method may be performed by a scheduling entity. The scheduling entity transmits control information in a control portion of the subframe, the control information corresponding to data information within the subframe, transmits the data information in a data portion of the subframe, receives a pilot signal from the set of subordinate entities in a pilot portion of the subframe, and receives an ACK/NACK signal from the set of subordinate entities in an ACK portion of the subframe. The ACK portion is subsequent to the pilot portion of the subframe. The ACK/NACK signal includes acknowledgment information corresponding to the data information. The control portion, the data portion, the pilot portion, and the ACK portion are contained in the same subframe.
