Systems And Methods For Latency Reduction For 2-Step Random Access Channel (Rach) Hybrid Automatic Repeat Requests (Harq)

View page
US Patent:
20220377801, Nov 24, 2022
Filed:
Oct 2, 2019
Appl. No.:
17/754465
Inventors:
- San Diego CA, US
Muhammad Nazmul ISLAM - Littleton MA, US
Linhai HE - San Diego CA, US
Amir AMINZADEH GOHARI - Santa Clara CA, US
Yuanning YU - Santa Clara CA, US
Enoch Shiao-Kuang LU - San Diego CA, US

Wanshi CHEN - San Diego CA, US
International Classification:
H04W 74/08
H04W 74/00
Abstract:
Wireless communications systems and methods related to the timing arrangements and the transmission gap configurations in 2-step random access channel (RACH) procedures to improve system latency and reliability of a RACH HARQ process are provided. The UE transmits a first message including a random access preamble and a payload, and then monitors for a second message in response to the first message during a random access response (RAR) window. In response to determining that no second message is received by the UE from the BS or a back off indicator is received within the RAR window, the UE re-transmits the preamble and payload of the first message after the RAR window lapses. In response to determining if the second message received within the RAR window carries a FallbackRAR or SuccessRAR, the UE then determines to re-transmit the payload of the first message based on the FallbackRAR, or to transmit an acknowledgement message based on the SuccessRAR.

US Patent:
20220338249, Oct 20, 2022
Filed:
Aug 14, 2020
Appl. No.:
17/626093
Inventors:
Jing LEI - San Diego CA, US
Linhai HE - San Diego CA, US
Yisheng XUE - San Diego CA, US
Seyong PARK - San Diego CA, US
Enoch Shiao-Kuang LU - San Diego CA, US

- San Diego CA, US
International Classification:
H04W 74/00
H04W 24/08
H04W 74/08
Abstract:
Aspects described herein relate to configuring and selecting preamble and payload occasions for performing two-step random access procedures. Configurations on preamble occasions, payload occasions, association pattern between the occasions and synchronization signal block (SSB) beams, and the rules for selecting preamble and payload occasions for random access message transmission can be determined by the network and signaled to user equipment (UE). Based on the configurations and rules, UE can measure the link level quality and select possible preamble and payload occasions for one or more SSB beams achieving a threshold signal quality. Sets of one or more preamble occasions and one or more payload occasions can be further determined based on whether the preamble and payload occasion(s) can achieve a threshold transmission latency. The one or more preamble occasions and one or more payload occasions can be used to transmit random access messages in the two-step random access procedure.

H04W 72/04
H04W 72/14
H04L 5/14
Abstract:
Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may perform, to a first base station and via a first radio frequency (RF) chain, at least a portion of a first uplink transmission associated with a first priority. The UE may receive, from the first base station or from a second base station and during the first uplink transmission, a physical downlink control channel (PDCCH) grant for a second uplink transmission associated with a second priority higher than the first priority. The UE may cancel a remaining portion of the first uplink transmission based at least in part on receiving the PDCCH grant for the second uplink transmission. The UE may perform, to the first base station or to the second base station and via a second RF chain, the second uplink transmission. Numerous other aspects are described.

International Classification:
H04L 12/24
H04B 7/0413
H04W 72/04
H04W 24/08
Abstract:
Methods, systems, and devices for wireless communications are described. In some systems, a user equipment (UE) may transmit assistance information to a base station to request an update or a modification to one or more communication parameters configured at the UE. Such communication parameters may include a quantity of uplink multiple-input multiple-output (MIMO) layers, a quantity of downlink MIMO layers, a minimum scheduling offset, a maximum quantity of component carriers, or a maximum aggregated bandwidth for a secondary cell group (SCG). In some implementations, the UE may transmit the assistance information requesting the update or modification to one or more of such communication parameters based on detecting that the UE satisfies one or more triggering conditions or thresholds.

US Patent:
20210314980, Oct 7, 2021
Filed:
Mar 31, 2021
Appl. No.:
17/219075
Inventors:
- San Diego CA, US
Seyed Ali Akbar Fakoorian - San Diego CA, US
Wei Yang - San Diego CA, US
James Beckman - La Jolla CA, US
Enoch Shiao-Kuang Lu - San Diego CA, US
Peter Gaal - San Diego CA, US
Yi Huang - San Diego CA, US
International Classification:
H04W 72/12
H04W 72/04
H04W 72/14
Abstract:
Methods, systems, and devices for wireless communications are described. The described techniques provide for a user equipment (UE) receiving a first transmission scheduling resources for a second transmission having a first priority. The UE may determine that one or more symbols of the second transmission are to be unused due to receipt of a cancellation indication or due to identifying a conflict, for example, with higher priority resources. Based on determining that the symbols are to be unused, the UE may determine that the base station will not reschedule the unused resources for another transmission, for example, having the first priority. The UE and the base station may communicate based on the determination.
