Abstract: Methods, systems, and devices are described for predicting a current random access transmission power detectable by a base station based on historical transmission power information. In one aspect, a mobile device may access a historical transmission power associated with a current state of the mobile device, with the historical transmission power based on mobility patterns of the mobile device.

Abstract: Methods, systems, and devices are provided that may address problems pertaining to effective transmit power control of a communications device operating in a wireless communications system. Some embodiments utilize mechanisms or techniques with dynamically adaptive steps sizes for transmit power control based on one or more trends. Some of these techniques may identify a trend in the transmit power control (TPC) commands and may adapt a TPC step size as a result. Other techniques may be utilized in which transmit power control is based on multiple interference estimates in a frame slot. Having multiple interference estimates at sub-slot intervals may provide additional transmit power control by allowing more transmit power adjustments, or more appropriate adjustments, for each slot. Metric calculations may be performed on one or more techniques to determine appropriate TPC operations.

Abstract: Methods, systems, and devices are described for defining a tracking area for a mobile device. The mobile device may determine that it is traveling along an identified route. The mobile device may send an indication to a core cellular network that it is traveling along the identified route and, therefore, refrain from sending tracking area update messages as it enters new tracking areas along the route. The core cellular network may receive the message and define a tracking area for the mobile device based on the information associated with the identified route. The core cellular network may define the tracking area and send page(s) to the mobile device without receiving tracking area update reporting messages from the mobile device as it travels along the identified route.

Abstract: Methods, systems, and devices are provided that may address problems to enabling a user equipment (UE) in connected mode on a normal bandwidth cell to make inter-frequency measurements on another normal bandwidth cell and a flexible bandwidth cell. Some embodiment utilize a set of compressed mode gap configurations for measuring both normal bandwidth and flexible bandwidth inter-frequency cells with the following modification for flexible bandwidth cells: reducing the coherent length used by the UE; using the same cell search parameters at the UE but modifying the compressed mode gap parameters to accommodate both normal bandwidth and flexible bandwidth cell search; and/or maintaining the compressed mode gap parameters but reducing the search window size during cell search coherent accumulation. Some embodiments may configure separate compressed mode measurements configuration for normal bandwidth and flexible bandwidth measurements.

Abstract: Methods, systems, and devices are described for orthogonal modulation of signals using maximal length sequences and Hadamard transforms. Modulation symbols to be transmitted are arranged into sequences indexed from 1 to 2n?1 for some integer n. A constant is added to the beginning of each sequence, which is then multiplied by a Hadamard matrix of size 2n×2n. The resulting sequences will be orthogonal and will have a first value of zero. The first value is discarded, and the sequence are reordered and associated with m-sequences. The signal is then transmitted. A cyclic prefix may also be transmitted. Upon receiving the transmission, a receiver may discard the cyclic prefix or use it for channel equalization. The receiver may then reorder the received signal, insert a zero, apply the 2n×2n Hadamard transform, discard the zero, and order the sequences again according to the index to retrieve the data.

Abstract: A method, an apparatus, and a computer program product for wireless communication are provided. The apparatus determines an operational state of a header compressor or a header decompressor by determining a transition between different operational states associated with the header compressor and/or by determining a transition between different operational states associated with the header decompressor. A persistent scheduling mode is changed in response to a change in the operational state of the header compressor. The persistent scheduling mode may be changed by activating uplink persistent scheduling when the operational state of the header compressor changes from a first order state to a second order state, and/or by deactivating the uplink persistent scheduling when the operational state of the header compressor exits the second order state.

Abstract: Methods, systems, and devices are provided that may support signaling, such as a Signaling Radio Bearer (SRB), over a flexible bandwidth carrier. For example, an SRB rate for a SRB over for a normal bandwidth carrier may be identified. A Transmission Time Interval (TTI) may be determined for the SRB over for the flexible bandwidth carrier that facilitates a SRB rate of the SRB over the flexible bandwidth carrier that maintains at least the SRB rate for the SRB over the normal bandwidth carrier. The determined TTI may be utilized for the SRB over the flexible bandwidth carrier, which may help avoid increased call setup delay, increased latency for handover, etc. that may be introduced in flexible bandwidth carrier systems. Some embodiments may include reducing spreading factors, increasing transmission power, and/or concatenating multiple transport blocks with respect to the SRB over the flexible bandwidth carrier.

The network may receive the message and define a tracking area for the mobile device based on the historical information. The network may define the tracking area and send page(s) to the mobile device without receiving location area update reporting messages from the mobile device.

Abstract: A method, apparatus and system provide for efficient use of communication resources for providing broadcast services in a communication system. A receiver receives a first broadcast controller identification from a first base station, and a second broadcast controller identification from a second base station. A controller coupled to the receiver determines whether the first and second broadcast controller identifications are associated with use of a common set of broadcast parameters. A transmitter transmits a request for transmission of a new set of broadcast parameters when the first and second broadcast controller identifications are not associated with use of the common set of broadcast parameters. After receiving the new set of broadcast parameters, the receiver uses the new set of broadcast parameters for receiving broadcast services.
