A disclosed example method involves, when a device is operating in a stationary mode and before a need of the device to communicate data, determining whether a stored timing advance is valid. When the stored timing advance is not valid, a valid timing advance is determined before the need of the device to communicate the data.

Timing advance enhancements for cellular communications

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.

Base stations and methods for receiving transmissions on an enhanced random access channel

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.

Communication stations and methods for transmitting on a random access channel

A method, network element and user equipment, where in one embodiment at a network element, allocating a measurement gap configuration for a user equipment (UE) capable of operating in a carrier aggregation environment using at least first and second component carriers; and sending the measurement gap allocation to the UE, the allocation indicating a first measurement gap configuration for the first component carrier, the first measurement gap configuration being different than a second measurement gap configuration allocated for the second component carrier. In another embodiment at a UE capable of operating in a carrier aggregation environment using at least first and second component carriers, sending a measurement gap preference to a network, the preference including preference information indicating a preference for a first measurement gap configuration for the first component carrier, the first measurement gap configuration being different than a second measurement gap configuration for the second component carrier.

Example communication stations and methods for transmitting additional information on an enhanced random access channel (RACH) are disclosed herein. An example method performed by a device involves generating an initial access burst for transmission on an enhanced RACH and transmitting the initial access burst using a timing advance. The timing advance is to cause the initial access burst to be received at the network within a single time slot of the enhanced RACH. The initial access burst includes at least one of information about capabilities of the device or information identifying the device. The example method also involves receiving a temporary block flow (TBF) assignment from the network in response to sending the at least one of the information about the capabilities of the device or the information identifying the device.

Methods and apparatus to avoid mobile station transmission of duplicate event-based and polled acknowledgments are disclosed. Example methods disclosed herein for a mobile station include determining whether an acknowledgment status of a first downlink data block classified as unreported is to be reported by a polled acknowledgment response to be sent in response to a poll received from a network, sending event-based acknowledgment information to report the acknowledgment status of the first downlink data block after determining that the acknowledgment status of the first downlink data block is not to be reported by the polled acknowledgment response, and refraining from sending the event-based acknowledgment information to report the acknowledgment status of the first downlink data block after determining that the acknowledgment status of the first downlink data block is to be reported by the polled acknowledgment response.

Systems and methods for allocating and transmitting uplink data block transmissions with piggy-backed ACK/NACK bitmap field are provided. In a specific example, a mobile station receives a request for a data block combined with control information (DBCCI). The mobile station responds by transmitting a DBCCI using at least one timeslot corresponding to a timeslot used for the request. At least some of the time, the mobile station sends data blocks in an order different than that would be otherwise used (e.g. block sequence order).

Systems and methods for allocating and transmitting uplink data block transmissions with piggy-backed ACK/NACK bitmap

Methods and systems for performing allocation of mixed-type combinations of slots are provided. Specifically, in a single assignment message, an allocation of slots over two framed and slots over four frames is performed. These can be RTTI and BTTI blocks for example.
