摘要:
Systems and methodologies are described that facilitate communicating a Buffer Status Report (BSR) from user equipment (UE) while reducing the employment of a RACH procedure. A BSR Prohibit time interval can be triggered by a receipt of uplink data to the UE. The BSR can be conveyed utilizing an uplink-shared channel (UL-SCH) if a Scheduling Request (SR) or a Semi-Persistent Scheduling (SPS) occurs within the duration of the BSR Prohibit time interval. The BSR can be communicated utilizing a RACH procedure if a SR or SPS occurs upon the expiration of the BSR Prohibit time interval.
摘要:
Methods, systems, and devices are described for intercepting requests from applications installed on a mobile device. The requests are system calls that establish communication channels for the mobile device. The requests are captured and held from reaching TCP/IP stack of an operating system executing on the mobile device. An intercepted request is aggregated with other intercepted requests. The aggregated requests are bundled together and released to the operating system upon the detection of a triggering event. The capture, holding, and aggregation of requests from applications occur when the mobile device is in a background mode.

A wireless terminal concurrently associates with multiple wireless local area networks. The wireless terminal may operate in power save mode on both of the WLANs to prevent a disruption of communication on either WLAN. The wireless terminal may adjust the times at which it listens for beacons to enable reception of beacon information even though the beacons for different WLANs may overlap in time. Beacon transmission times also may be scheduled to avoid overlapping transmissions of beacons on different WLANs.

The disclosure is directed to an apparatus and method for encoder initialization and communications. The apparatus may include a database and an encoder module. The database may be configured to receive a plurality of parameters to be used for operation of the encoder module. The database may be further configured to store the plurality of parameters and to provide the plurality of parameters to the encoder module. The encoder module includes an encoder configured to be initialized based on the plurality of parameters from the database. When invoked, the encoder may rely on the database to initialize rather than performing measurements on the current signal that is to be encoded. In one aspect, the apparatus may be an access terminal that can seamlessly switch between different domains, different networks, different base stations, and different access points.
摘要:
Broadcast or multicast traffic is classified into different types of traffic and different transmission schedules associated with each of the different types of traffic. The different types of broadcast and multicast traffic may be implemented in an 802.11-based system where an access point is configured to classify broadcast and multicast traffic into different types and assign different transmission schedules to each of the different traffic types. An associated wireless station may thereby wake from a power save mode only at intervals corresponding to delivery times of the types of traffic that the wireless station has elected to receive. In some aspects the different types of broadcast and multicast traffic may comprise user plane traffic and control plane traffic.

Certain aspects of the present disclosure provide a method for bearer count alignment during handover of a user equipment (UE) from a first radio access technology (RAT) to a second RAT. The UE establishes radio resource control (RRC) connections with the second RAT and transmits data radio bearer (DRB) capability of the UE to the second network. The second network utilizes this information to set up the DRBs with the UE.
摘要:
Techniques for controlling the operation of user equipments (UEs) to mitigate emissions out of band are described. A base station may identify a UE potentially causing excessive emissions out of band due to transmission of control information and may schedule the UE to reduce the emissions out of band. In one design, the base station may schedule the UE to send control information on a Physical Uplink Shared Channel (PUSCH) instead of a Physical Uplink Control Channel (PUCCH). In another design, the base station may assign the UE with resources for the PUCCH to send control information. The assigned resources may be selected to mitigate the emissions out of band and may be (i) located within a target frequency range, (ii) located away from a frequency band to be mitigated with the emissions out of band, or (iii) obtained with a reuse scheme and have less inter-cell interference from other UEs.
摘要:
Transmit power is controlled for a first uplink data transmission on Physical Uplink Shared Channel (PUSCH) during random access channel (RACH) procedure. Power control adjustment for the first PUSCH transmission is performed relative to the power spectral density used for successful PRACH transmission as adjusted for bandwidth difference, etc. The uplink Physical random access channel carries the RACH information that is transmitted by the user equipment (UE) during registrations or base station originated calls. A PRACH is composed of a number of preambles and a message portion. The preambles are a series of radio frequency power “steps” that increase in power according to the power step setting until the maximum number of preambles is reached or the base station acknowledges. Once the UE receives a positive indication, it transmits the message portion of the PRACH which consists of message data and control data with independent power gain control.
摘要:
A wireless communication system provides for a random access channel (RACH) procedure for user equipment (UE) to request access to an uplink channel. From a physical layer perspective, an evolved Base Station (eNB) responds with a random access preamble and a random access response (RAR) of a fixed length message, such as 21 bits or 20 bits with a reserved bit for future extensions. In answer to a need that exists for an RAR to accommodate variations in system bandwidth, an approach to encoding a truncated resource block (RB) assignment of the RAR in manner in which the UE can interpret the RAR without loss of information. Thereby, needs for achieving RACH procedures and existing channel resources can be realized.
摘要:
In a wireless communication system, user equipment (UE) is provided, one or more set of rules are provided for the UE to handle the processing during a measurement gap. In some aspects, the gap measurement may be ignored. In some aspects, the processing is stored and handled at a later in time and gap measurements are performed. Depending on the system, the measurements performed during the gaps may be UE implementation dependent, wherein the UE determines whether to perform the measurement for a given gap. In some instances, the UE may not perform measurements during the gap, thereby giving priority to other processing, such as RACH processing. Depending on the type of processing required (DL-SCH, UL-SCH, TTI bundling, RACH or SR), the UE may store requests and process the measurements during the gap or ignore the gap measurement as if there were no gaps.
