Abstract: Described herein are techniques related to data communications using a data packet having at least one frame with a robust preamble for use over media having a high degree of non-stationary noise (e.g., impulsive noise). The described techniques employ a preamble with a structure having multiple transitions between the preamble sections. Each transition indicates the start of the upcoming frame. With the techniques described herein, if noise damages the transitions between such sections beyond recognition, the receiver can still determine the frame start time from the one or more of the undamaged transitions. Thus, the robustness of communications via the noisy media is significantly increased. This Abstract is submitted with the understanding that it will not be used to interpret or limit the scope or meaning of the claims.

Abstract: A communications device establishes a communications context for communicating data packets using a packet communications bearer from the communications device via the mobile communications network. A controller of the communications device is configured to identify that the communications device can enter a stasis state because no data packets are available for transmission for a predetermined time via the packet communications bearer or there are no data packets to receive via the packet communications bearer, to transmit a stasis state message to the mobile communications network, and to store information relating to the communications context associated with the packet communications bearer in a data store. The stored information can be used by the controller to re-establish the packet communications bearer to transmit and/or receive data packets using the packet communications bearer, the communications device thereby entering the stasis state.

Abstract: In an example of wireless communications, an access point may send a downlink frame to multiple stations. The downlink frame may include information indicative of a cyclic prefix length to be utilized by the stations. In response, some or all of the stations may transmit their respective uplink frames to the access point. A cyclic prefix for a portion of each respective uplink frame may have a cyclic prefix length corresponding to the information included in the downlink frame. The downlink frame may be, for example, a beacon frame or a trigger frame. A trigger frame may allocate resources for uplink orthogonal frequency division multiple access (OFDMA) transmission. Other methods, apparatus, and computer-readable media are also disclosed.

Abstract: A receiving apparatus for SNR estimation of a signal such as the LTE PUCCH, transmitted over a channel of an OFDM wireless communication system. The proposed apparatus brings determines the noise power level in the frequency domain based on a noise covariance matrix where timing errors are back compensated in the equation since timing error is expressed a complex exponential therein. Contrary to the common methods used for determining the noise power level, in the present invention deriving the channel estimate components from the pilot symbol(s) comprised in the received signal is not required. Based on the present invention, user's transmit power is reduced thereby improving battery power longevity. Further, since interference is reduced, more users may be multiplexed together in the same resources. A method and a computer program product are also claimed.

Abstract: In a WCDMA mobile communication system, when the amount of packet traffic transmitted to or received from a UE decreases during a predetermined time in a CELL_DCH state in which a WCDMA packet data connection has been established, the UE transitions to a CELL_FACH state by a radio network controller (RNC). Thereafter, it is determined if there is no transmitted or received packet traffic during a certain time in the CELL_FACH state (which is an RRC state in which an RRC connection has been connected, and the dedicated physical channel has been released). When it is determined that there is no transmitted or received packet traffic during the certain time, the UE requests a network to release the RRC connection by utilizing a Signaling Connection Release Indication (SCRI) message. The invention enables a UE to check a packet transmission or reception flow, and to directly transmit the SCRI message to the network.

Abstract: Channel state feedback is provided from a UE to a base station as a first, detailed or a second, less detailed type of channel state feedback information. Initially it is determined whether the UE has received an uplink grant from the base station or not. If the UE has received an uplink grant, a first type of channel state feedback information is transmitted to the base station on the granted resource. If, however, the UE has not received an uplink grant, a second type of channel state feedback information is transmitted to the base station. Different types of channel state feedback information enables a UE and an associated base station to use available resources more efficiently, when requesting for and delivering channel state feedback information.

Abstract: Uplink signals transmitted from each of a plurality of UE devices being served by a serving eNB are received at a neighbor cell eNB. Information regarding the uplink signals received by the neighbor cell eNB is then sent to the serving eNB. The UE devices are identified based on the information. An aggregate load level of the UE devices is determined based on resource load requirements of each UE device. In some instances, it is determined which of a plurality of deactivated neighbor cells should be activated based on load levels associated with one or more UE devices that are determined to be near each of the plurality of deactivated neighbor cells.
