H04L 1/18

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. Numerous other aspects are provided.

Abstract:

A first apparatus may puncture, in at least two subslots, a first type of data or control information with a second type of data or control information. The first apparatus may bundle the least two subslots within a subframe, and the subframe may include a portion for carrying acknowledgment (ACK)/negative acknowledgment (NACK) information associated with the second type of data or control information. The first apparatus may communicate with a user equipment (UE) during the at least two subslots within the subframe. A second apparatus may receive ACK/NACK information associated with a second type of data or control information. The second apparatus may reduce a transmission power for a first type of data or control information during a subsequent subframe when the ACK/NACK information indicates a negative acknowledgement.

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 5/00
H04B 7/06
H04L 1/18
H04W 72/04

Abstract:

An apparatus may configure x subframes with a subslot configuration that includes y subslots, y being greater than x. In an aspect, each subslot of the y subslots may include a first portion having one or more symbols for carrying at least one of data or control information, a second portion having a gap, and a third portion for carrying ACK/NACK information associated with the first portion. In an aspect, the second portion may be between the first portion and the third portion. In an aspect, the second portion and the third portion may include at most one symbol. The apparatus may send information indicating the subslot configuration to at least one neighboring base station. The apparatus may communicate content with a user equipment (UE) during at least one of the y subslots.

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.
