Assignee:

QUALCOMM Incorporated - San Diego CA

International Classification:

H04W 52/02

US Classification:

370311

Abstract:

The described aspects include a user equipment (UE) apparatus, network component, and corresponding methods of communicating power saving information using common uplink messages. By using a resource update message to communicate power saving information from a UE, the UE need not request and establish resources with the network for requesting a power state that uses less power than a current state. Similarly, in UE mobility, the UE can indicate previous power saving information to a target Node B to cause the target Node B to refrain from assigning resources to the UE.

Assignee:

QUALCOMM Incorporated - San Diego CA

International Classification:

H04W 52/02

US Classification:

370311

Abstract:

Apparatus and method for wireless communication in a wireless communication network includes receiving a power saving request from an application on a wireless device and determining whether the wireless device has data waiting for transmission in response to the received power saving request. The apparatus and method also includes starting a buffer timer when the data waiting for transmission is determined to exist, buffering the power saving request until expiration of the buffer timer, and triggering transmission of a dormancy request to a network component based on whether the data waiting for transmission is determined to exist.

International Classification:

H04W 52/02
H04W 76/27

Abstract:

Methods, systems, and devices are described for enhanced power savings in wireless devices through mobile initiated dormancy procedure. A user equipment (UE) may establish radio resource control (RRC) connectivity with a base station of the network, and transmit and receive one or more distinct signaling messages for dormancy state initialization and suspension at the UE. Dormancy state implementation at the UE may conserve available power resources at the UE during periods of inactive data transaction. The one or more signaling messages may contain a single or multi-bit indication for the receiving device, and may be transmitted via direct signaling on upper layer protocols of the data network or mapped to allocated resources of a data transmission. The signaling messages may sustain synchronization between the interpreted functional mode of the UE at the base station and the implemented mode at the UE.

International Classification:

H04W 16/28
H04W 64/00

Abstract:

Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may determine location information regarding the UE; and activate a receive beam of the UE in at least one symbol, associated with at least one transmit beam of at least one base station, based at least in part on the location information, wherein the UE is configured to activate the receive beam based at least in part on mapping information, at least partially determined by the UE, that indicates that the receive beam is associated with the location information. Numerous other aspects are provided.

International Classification:

H04W 36/00
H04M 1/253
H04L 29/06
H04W 36/30
H04W 28/02

Abstract:

Methods, systems, and devices for wireless communications are described that provide for call continuity following radio link failure (RLF) through re-establishment of a voice call using a same or different radio access technology (RAT) before the call is dropped. Upon detection of RLF on a connection supporting a voice call, a UE may initiate a drop call timer and scan for available connections. The voice call may be attempted to be re-established if a connection is available on using a RAT of an existing connection. The voice call in such cases may continue without the call being dropped. Upon expiration of the drop call timer, the UE may attempt to establish a connection using a RAT identified during the duration of the drop call timer.

Abstract:

Methods for receiving emergency messages on a mobile communication device having a first subscription and a second subscription sharing a radio frequency (RF) resource may include prioritizing, by a processor of the mobile communication device, the first subscription for a predetermined time period in order to receive an emergency message, determining, by the processor, whether the first subscription should be de-prioritized before the predetermined time period expires based on a reception history of the first subscription during the predetermined time period, and tuning the RF resource to the second subscription before the predetermined time period expires in response to determining that the first subscription should be de-prioritized before the predetermined time period expires.
