US Classification:

455522, 455 69, 455 6711, 4551151

Abstract:

Determining a power control group boundary includes receiving a plurality of samples having power control groups, where each power control group corresponds to a time period. The following are repeated for a predetermined number of iterations: a window is set at a point of a sample; a number of power control bits within the window at the point is determined; and the window is moved to a point of a next sample. A point at which the window has the largest number of power control bits is identified. A power control group boundary is determined in accordance with the window at the identified point.

US Classification:

Abstract:

An apparatus may include a non-linear module, a control module, and a calibration module. The non-linear module produces an output signal from an input signal. The control module selects, upon an occurrence of a calibration condition, a calibration operation from two or more calibration operations. Each of the two or more calibration operations may generate one or more correction values for the non-linear module. Further, each of the calibration operations produces the input signal from a pre-input signal. This selected calibration operation is performed by the calibration module. The two or more calibration operations include a first calibration operation and a second calibration operation. The first calibration operation produces the input signal from the pre-input signal according to a predictive technique. The second calibration operation produces the input signal from the pre-input signal according to a non-predictive technique.

International Classification:

H04M 15/00

US Classification:

370259

Abstract:

A method and apparatus are described for providing triggering services over multiple access networks. A triggering service server (TSS) architecture includes a triggering identity function (TIF) which maintains a database of device and application identifier mappings across multiple access networks, triggering capabilities and triggering preferences. The TSS also includes a triggering decision function (TDF) that uses information from the TIF and determines how triggers should be performed towards a device and/or an application hosted on a particular device. The TSS also includes triggering gateways (T-GWs) that perform triggering in different domains. A “not-registered-triggerable” state may be used to indicate whether an entity, such as a device, application or user can receive triggers although it is not registered in a specific access network. Methods and apparatus are also described for implementing various unassisted triggering and assisted triggering procedures using wireless transmit/receive units (WTRUs), application servers (ASs) and service capability servers (SCSs).

International Classification:

H04L 29/08

US Classification:

709201

Abstract:

A method and apparatus may use multiple URIs (MU) in a single request message for machine-to-machine (M2M) communication networks. Multiple single URI (SU)-type request messages may be received from an application client (e.g. a constrained application protocol (CoAP)/hypertext transfer protocol (HTTP) client) at a (CoAP/HTTP) intermediary node. The multiple SU-type request messages may be aggregated into a single MU-type request message at the intermediary node, and the single MU-type request message may be transmitted to a (CoAP/HTTP) server. A multiple value (MV)-type response message may be received from the (CoAP/HTTP) server. The MV-type response message may be deaggregated into multiple single value (SV)-type response messages. The multiple SV-type response messages may be transmitted to the (CoAP/HTTP) client.

Abstract:

In NR, a slot structure of a UE may be dynamic due the number of symbols of PDCCH and whether the slot has UL data, among other considerations. Additionally, to support multi-TRP/multi-panel/multi-BWP operation, a UE may be configured with multiple TRSs, and when a UE needs to receive multiple TRSs in the same slot, efficient signaling of the TRSs is important because of the high overhead involved. During a transmission, a UE may need to do beam switching when there is a beam failure, but existing systems do not have mechanisms for the UE to synchronize time and frequency with a new beam. Further, when a UE switches to a new beam, the effect on scheduled TRS transmission for old beams is unclear. Fine frequency and time tracking may also be required during an initial access procedure. Existing NR systems do not address how a UE may perform time and frequency tracking during an initial access procedure. Additionally, URLLC data may need to be transmitted to a UE immediately in an NR system. Existing NR systems do not address sending a TRS to a UE with URLLC data. Embodiments described herein address these and other issues.
