Abstract:
Methods and apparatus for mobile station transmissions in response to network acknowledgment polling are disclosed. An example method in a mobile station disclosed herein comprises receiving a poll from a network, the poll requesting piggy-backed ACK/NACK (PAN) information, and transmitting a control message in response to the poll if a previously transmitted data block is associated with a tentative acknowledgment state, the control message including acknowledgment information.
Abstract:
Systems and methods for transmission of measurement reports are provided. In some cases, once a mobile station transmits a measurement report for a cell, such as an uncontrolled cell, then the mobile station transmits some further minimum number of measurement reports. In some cases, a mobile station can only transmit measurement reports for a cell up to some maximum or for some specified time. The mobile station transmits measurement reports using two formats. In the first, the cell is identified using routing parameters; in the second, the cell is not identified using routing parameters. The network is able to associate messages sent using the two formats.
Abstract:
Example base stations and methods for receiving transmissions on an enhanced random access channel (RACH) are disclosed herein. An example method for receiving transmissions on an enhanced RACH from a device such that an initial access burst is received in a single time slot from the device involves receiving the initial access burst from the device on the enhanced RACH. The initial access burst is sent by the device using a timing advance determined at the device. The initial access burst includes at least one of an identifier or user data. The enhanced RACH is a contention-based uplink-only channel requiring use of timing advances for transmissions thereon.
Abstract:
Example communication stations and methods for transmitting on a random access channel (RACH) in wireless networks are disclosed herein. An example method for transmitting on an enhanced RACH by a device such that an initial access burst is received in a single time slot by a wireless network involves determining a timing advance, the timing advance being associated with a serving cell. The example method also involves transmitting, using the determined timing advance, the initial access burst, on the enhanced RACH, that includes at least one of an identifier or user data.
Abstract:
Example methods and apparatus to initiate data transfers using capabilities classes of pre-defined capability configurations are disclosed. In accordance with a disclosed example method, a message is generated to initiate a data transfer session between a mobile station and a network. A code value from a plurality of code values is selected. Each of the code values is pre-defined to indicate a respective subset of different types of radio access capabilities of the mobile station. The selected code value is included in the message. The message is sent from the mobile station to the network.
Abstract:
Example methods and apparatus to signal access-stratum capabilities of mobile stations for data transfer sessions are disclosed. In accordance with a disclosed example method a capabilities structure is selected from a group of capabilities structures. The capabilities structure is indicative of a set of radio access capabilities of a mobile station for a data transfer session between the mobile station and a network. A message is formatted based on the selected capabilities structure to include radio access capabilities information of the selected capabilities structure. A code is included in the message to indicate the presence of the selected capabilities structure in the message. The message is sent from the mobile station to the network.
Abstract:
A system and method allows for providing emergency service, whether the service is full or limited, to wireless devices using non-IMS packet traffic based methods or Access Stratum/Non-Access Stratum (AS/NAS) signalling based methods. To do so, a system and method for utilizing a Packetized Emergency Message (PEM) is provided.
Abstract:
A system and method allows a network, in response to a cell reselection notice, to serve a wireless, wireless device sufficient data to complete a pending data transfer instead of performing the immediate cell change. Appropriate allocation of radio resources to the wireless device in the current serving cell and before cell change allows reduced packet data transfer latencies for small data sessions, better load balancing and traffic resourcing between cells, appropriate allocation of uplink resources in the new target cell, and enhanced control over network congestion.
Abstract:
Methods and apparatus to monitor a channel to determine neighbor cell information are disclosed. An example method for a first mobile station to determine cell information for a first cell disclosed herein comprises monitoring a channel for messages containing cell information, receiving a first message via the monitored channel and addressed to a second mobile station, the first message including first cell information, and storing the first cell information for a time period after receiving the first message.
Abstract:
A method is suggested for communicating to a mobile station which timeslots are configured as packet data channel pairs and on which of these packet data channel pairs the mobile station is assigned resources, wherein a description of packet data channel pairs is separated into “configuration” and an “assignment”.
