METHOD AND SYSTEM FOR REFRESHING MEMORY OF A PORTABLE COMPUTING DEVICE (18249925)

Main Inventor

Pranav AGRAWAL

Brief explanation

The abstract describes a system for managing memory refresh requests in a high-level operating system (HLOS).

• The HLOS kernel can generate memory refresh requests with specific address ranges and sizes.
• A resource power manager is connected to the kernel and the memory, which consists of multiple memory ranks.
• When the resource power manager receives a memory refresh request, it checks if the memory ranks are symmetrical or asymmetrical.
• If the memory ranks are symmetrical, the resource power manager evenly distributes the memory refresh request across all ranks in a parallel manner.
• If the memory ranks are asymmetrical, the resource power manager determines the appropriate type of memory refresh: linear only, interleave with linear, or interleave only.

Abstract

A kernel of an HLOS may originate one or more memory refresh requests. Each memory refresh request may have a first memory address range and a size value. A resource power manager may be coupled to the kernel and coupled to memory. The memory may have a plurality of memory ranks. The resource power manger may receive a memory refresh request from the kernel. The resource power manager may then determine if the plurality of memory ranks is either symmetrical or asymmetrical. If the memory ranks are symmetrical, then the resource power manager distributes the memory refresh request evenly and in a parallel manner across the symmetrical memory ranks. If the memory ranks are asymmetrical, then the resource power manager will then determine if the memory refresh request should be one of: a linear only memory refresh; an interleave with linear memory refresh; or an interleave only memory refresh.

Brief explanation

- The patent application describes a method for managing uplink transmissions on multiple radio access technologies (RATs) in a user equipment (UE).

- The UE receives separate uplink grants for two different RATs, such as 5G NR and LTE. - The UE selectively drops uplink transmissions on specific resource blocks to control the amount of time allocated for concurrent uplink transmissions on both RATs. - This scheduling of uplink transmissions helps in managing the overall time and resources used by the UE for transmitting data on multiple RATs. - The UE also adjusts the transmission of a Buffer Status Report (BSR) on the first RAT based on the scheduling of concurrent uplink multi-RAT transmissions during a specific period of time. - During another period of time, the UE does not transmit a BSR on the first RAT when concurrent uplink transmissions on both RATs are not allowed to be scheduled. - This approach helps in optimizing the utilization of resources and managing the coordination of uplink transmissions on multiple RATs in the UE.

Mahmoud Taherzadeh Boroujeni

Brief explanation

- This patent application describes methods, systems, and devices for wireless communications and waveform type switching.

- If a user equipment (UE) receives a signal to switch waveform type after transmitting a first portion of uplink messages, it can use a different waveform type to transmit the remaining portion of the messages. - The UE can request to change the waveform type used for uplink transmissions if certain conditions are met. - The UE can determine the waveform type to use for an uplink transmission during a random access procedure based on information received in a downlink transmission during the same procedure.

If a user equipment (UE) receives an indication to switch waveform type after transmitting a first portion of a set of uplink messages, the UE may use a different waveform type to transmit a remaining portion of the set of uplink messages. If one or more conditions are satisfied at the UE, then the UE may transmit, to a network entity, a request to change the waveform type used for uplink transmissions by the UE. The UE may determine a waveform type to use for an uplink transmission as part of a random access procedure based on information included in a downlink transmission that is received as part of the random access procedure.

When establishing a connection via sidelink, two or more UEs may agree on a resource pattern for a set of sidelink resources where a first UE has higher priority than a second UE for a first subset of resources. The first UE may be given higher priority in the first subset of resources through adjustments to a channel access procedure for requesting channel access, adjustments to one or more access thresholds or channel access priority classes, contention window adjustments, or any combinations thereof. Layer one signaling may be used to reconfigure channel access priority and the traffic pattern between UEs.

UNICAST MEASUREMENT AND DETERMINATION FOR SPACE-DIVISION MULTIPLEXED TRANSMISSION WITH MULTIPLE TRANSMISSION RECEPTION POINTS (18034033)

Main Inventor

Hui GUO

Brief explanation

This patent application describes a method for improving the performance of unicast links between multiple user equipments (UEs) in a wireless communication system. The method involves the use of multiple transmit and receive points (TRPs) in the UEs to measure the channel quality and interference levels on the unicast links.

• The first UE sends a reference signal (RS) from one of its TRPs to the second UE on a first unicast link.
• Based on the RS received, the first UE measures the channel quality of the first unicast link from the second UE and the interference level from a third UE on a second unicast link.
• The first UE then sends another RS from a different TRP to the third UE on the second unicast link.
• Based on the second RS received, the first UE measures the channel quality of the second unicast link from the third UE and the interference level from the second UE on the first unicast link.
• The first UE applies spatial division multiplexing (SDM) techniques to optimize the performance of both unicast links based on the measured channel quality and interference levels.

Overall, this patent application proposes a method for dynamically adjusting the transmission parameters of unicast links between UEs based on real-time measurements of channel quality and interference levels, leading to improved performance and reliability of the wireless communication system.

Abstract

A first UE transmits, on a first unicast link to a second UE, a first RS from a first TRP of the first UE. The first UE receives, based on the first RS transmitted, a first channel measurement for the first unicast link from the second UE and a first interference measurement for a second unicast link from a third UE. The first UE transmits, on the second unicast link with the third UE, a second RS from a second TRP of the first UE. The first UE receives, based on the second RS transmitted, a second channel measurement for the second unicast link from the third UE and a second interference measurement for the first unicast link from the second UE. The first UE applies SDM for the first unicast link and the second unicast link based on the received channel and interference measurements.
