Abstract:

Certain aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment may receive, from a base station, an indicator associated with a hybrid automatic repeat request (HARQ) process, wherein the indicator indicates a number of mini-slots to be bundled for a HARQ transmission of the HARQ process; and decode the HARQ transmission based at least in part on the mini-slots. In some aspects, a base station may transmit an indicator, associated with a HARQ process, to a user equipment, wherein the indicator indicates a number of mini-slots to be bundled for a HARQ transmission of the HARQ process; and transmit the HARQ transmission to the user equipment using the mini-slots.

Abstract:

Transmission time interval (TTI) bundling for ultra-reliable low-latency communication (URLLC) uplink and downlink transmissions is discussed in which a base station or user equipments (UEs) determine conditions for one or more served UEs that would indicate enabling TTI bundling for data and/or control transmissions. The serving base station transmits an enablement signal signifying that TTI bundling will be performed for data and/or control transmissions. The enablement signal may include a bundle length for the transmission bundle. The data or control signal packets may then be repeatedly transmitted to the UEs a number of times corresponding to the bundle length.

International Classification:

H04L 5/02
H04L 5/00

Abstract:

Various aspects are described for schemes that address the potential puncturing of important reference signals (RSs) for enhanced mobile broadband (eMBB) applications, such as demodulation reference signal (DMRS), channel state information reference signal (CSIRS), tracking reference signal, and general reference signal. The schemes can be used for recovery of eMBB's RS puncturing from dynamic multiplexing of ultra-reliable-low-latency communications (URLLC) and eMBB. The schemes include a block-based scheme and an over-provisioning scheme. The schemes modify an existing RS pattern before puncturing occurs in response to a presence of the URLLC traffic. In addition, there can be an option not to use (e.g., disable) time-domain orthogonal cover code (TD-OCC) for the RSs.

International Classification:

H04L 1/00
H03M 13/11
H04L 1/08

Abstract:

Methods, systems, and devices for wireless communication are described. In some examples, a wireless device (e.g., a user equipment (UE) or a base station) may encode a codeword from a set of information bits using an LDPC code. The wireless device may then transmit multiple versions of the codeword to improve the chances of the codeword being received. In some aspects, the wireless device may use the techniques herein to generate self-decodable redundancy versions of the codeword to be transmitted to the receiving device. Accordingly, a receiving device may be able to identify information bits from one or more redundancy versions of the codeword even if the receiving device failed to receive an original transmission of the codeword.

Abstract:

The present disclosure provides self-decodable redundancy versions for a systematic code. An apparatus for wireless communications includes at least one processor coupled with a memory and comprising encoder circuitry configured to encode a set of information bits using a systematic code to generate an encoded bit stream with information bits and parity bits, and bit ordering circuitry configured to re-order bits in the encoded bit stream to distribute the information bits and the parity bits. The apparatus includes a transmitter configured to transmit the re-ordered bits in accordance with a radio technology via one or more antenna elements situated proximate the receiver.

International Classification:

H04W 72/12
H04W 72/04
H04W 28/06

Abstract:

Methods, systems, and devices for wireless communication are described that provide for establishing periodic resources that may be used for low latency communications. An indication channel may be provided that may indicate that one or more higher latency transmissions may be punctured with low latency communications that are transmitted outside of the periodic resources. In some cases, the indication channel may be transmitted only in subsets of time resources, such as mini-slots of time resources within a slot, and a user equipment (UE) may monitor the indication channel to determine that a transmission is punctured. The UE may not monitor the indication channel in the periodic resources, and may thus conserve power compared to monitoring the indication channel in all time resources.

International Classification:

H03M 13/11
H04L 1/00

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.
