Abstract: Aspects of the present disclosure provide apparatuses, methods, and processes that can determine the number of concurrent hybrid automatic repeat request (HARQ) processes at a HARQ entity to facilitate efficient use of HARQ buffers and/or resources across different operating modes. An exemplary apparatus is configured to determine a number of HARQ processes based on a number of HARQ buffers, a maximum buffering time, and a slot duration. The apparatus maintains one or more HARQ processes at a HARQ entity up to the determined number of HAR processes and communicate with the one or more other devices utilizing the one or more HARQ processes.

Abstract: Certain aspects of the present disclosure relate to method and apparatus for wireless communication. In certain aspects, the method generally includes transmitting first control information during a first transmission time interval (TTI), wherein the first control information indicates resources within a TTI allocated for a data transmission, and transmitting the data using the indicated resources. The method further includes transmitting second control information, wherein the second control information also indicates the resources for the data transmission.

Abstract: Bursty interference or puncturing may be identified, either by a user equipment (UE) or by a base station. In response, a protection scheme may be applied to protect communications from the bursty interference or puncturing. The protection scheme may include using both time and frequency interleaving of code blocks in the communications. The protection scheme may also include modifying the modulation and coding scheme (MCS), coding rate, precoding matrix index (PMI), or rank indicator (RI) used in the communications. The protection scheme may also include using a universal low-density parity check (LDPC) code in the transmission of the communications.

Abstract: Systems, devices, and methods associated with interference aware sounding reference signals are provided. A method for wireless communication includes receiving, at a wireless communication device in communication with a first base station, an interfering signal from a second base station (or other base stations); determining, at the wireless communication device, a spatial direction of the interfering signal; and transmitting, with the wireless communication device, a signal to the first base station based on the spatial direction of the interfering signal. Another method of wireless communication includes receiving, at a first base station, a signal from a wireless communication device, the signal based on a spatial direction of an interfering signal received by the wireless communication device from a second base station (or other base stations); transmitting, with the first base station, a downlink communication to the wireless communication device, the downlink communication beamformed in the spatial direction based on the signal received from the wireless communication device.

Abstract: Methods, systems, and devices for wireless communication are described. Some wireless communications systems support mobile broadband (MBB) communications and low latency communications. To accommodate low latency communications, a base station may identify resources allocated for MBB communications, and the base station may reassign (or puncture) these resources for low latency communications. The base station may transmit an indication of the reassigned (or punctured) resources to one or more user equipments (UEs). The base station may transmit an indication of the reassigned resources over a designated indication channel during a time period that is being reassigned for low latency communications (e.g., using a current indication). The base station may also transmit another or complementary indication of the reassigned resources in a subsequent time period (e.g., using a post indication), which may include supplemental or additional information.

Abstract: Aspects of the present disclosure relate to low density parity check (LDPC) coding utilizing a configurable circular buffer for rate matched transmissions. The circular buffer may be configured based on a selected mother code rate and a fixed circular buffer length. For example, the respective sizes of the systematic and parity bit sections of the circular buffer may be variable based on the selected mother code rate.

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: Some aspects of the disclosure provide for wireless communication systems in which scheduling information is transmitted to a scheduled entity to schedule transmission of uplink feedback control information by the scheduled entity. The feedback control information may be transmitted in short uplink control bursts or long uplink bursts. Selection between short uplink control bursts and long uplink bursts may be based on power headroom at the scheduled entity, interference in the short uplink control burst or the long uplink burst, loading of the short uplink control burst or the long uplink burst or processing capability of the scheduled entity.

Abstract: Aspects of the disclosure relate to wireless communication systems configured to provide techniques for managing the cyclic prefix (CP) type of a transmission as a function of one or more parameters, such as the transmission type (e.g., the type of channel or signal), the resources utilized for the transmission, or the tone spacing of the transmission. In some examples, at least a portion of the downlink and/or uplink control channels or signals utilize a CP having one duration, while other control channels or signals and/or traffic channels may utilize either the same CP or a different CP having a different duration. The CP type or duration for a given transmission may be indicated in various manners.

Abstract: A method, an apparatus, and a computer program product for wireless communication are provided. The method includes scheduling at a scheduling entity, a first frame for transmission over a wireless network that supports time division duplexing (TDD), where the first frame includes a first duplex symbol that includes a first bandwidth to be used for uplink transmission to the scheduling entity and a second bandwidth to be used for downlink transmission from the scheduling entity, and using the second bandwidth to transmit scheduling information while the first frame is being transmitted. The scheduling information may be related to a second frame that is scheduled to be transmitted immediately after the first frame. The scheduling information includes an uplink grant or a downlink grant.
