Abstract: A wireless communication system as described here employs control signaling for contention-based uplink access from user equipment devices to a base station. Contention-based access configuration is performed via physical downlink control channel signaling. Configuration data sent to the user equipment devices identifies multiple contention-based access zones, along with minimum power headroom values for each contention-based access zone. A probability factor may also be used to lower collision possibility by influencing whether the user equipment devices perform contention-based uplink access. An uplink grant message can be used to acknowledge contention-based transmission; contention resolution is achieved implicitly via the uplink grant.

Abstract: A method, a network base station, and a user communication device for transmitting control data are disclosed. A processor 210 may encode a rescue frame 502 of a set of frames with a higher rescue overhead to data ratio. The processor 210 may encode an ancillary frame 504 of the set of frames with a lower rescue overhead to data ratio. A transceiver 240 may transmit the set of frames.

Abstract: An apparatus and method for enabling Buffer Status Reports in a Long Term Evolution communication system includes a step (400) of determining a higher than normal likelihood of receiving a first buffer status report on a first uplink grant. A next step (402) includes increasing a reliability of the first uplink grant in response the higher than normal likelihood. Other next steps can include detecting (404) that the first Buffer Status Report transmission Hybrid Automatic Repeat Request process failed and triggering (406) a second Buffer Status Report transmission in the user equipment in a next uplink grant.

Abstract: A scheduler associated with a base station of a wireless communication network dynamically compensates for uplink bandwidth that has been re-assigned (stolen) by a mobile station (MS) to transmit a control message. The scheduler allocates a preset amount of bandwidth to the MS for data transmission. The scheduler detects bandwidth stealing activity and evaluates when bandwidth stealing is justified on he part of the MS. The scheduler provides additional bandwidth to appropriately compensate for the stolen bandwidth when bandwidth stealing is justified, in order to maintain the quality of service of the data traffic connection.

Abstract: A method and apparatus are disclosed that includes a user equipment (104) sending a first buffer status report to an eNode B (102) to (210) indicate an amount of data in a buffer that is to be sent. After the first buffer status report is sent, the amount of data in the buffer can change (216) so that the user equipment sends (218) a second buffer status report to indicate the change in the amount of data in the buffer that is to be sent.

Abstract: A technique for reducing a time delay between an application output at a subscriber station and uplink resource allocation for the subscriber station includes scheduling, between periodic uplink resource allocations, one or more probe uplink resource allocations for the subscriber station. Next, respective information in at least one of the one or more probe uplink resource allocations is received at an access point. Finally, subsequent periodic uplink resource allocations are scheduled based on at least one of the one or more probe uplink resource allocations.

Abstract: An apparatus and method for monitoring (310) at least one factor relating to a wireless communication system (100) is provided such that a synchronization signal is sent (320) to at least one base transceiver station (130) neighboring a primary base transceiver station (120) at least in part according to a predetermined function of the monitored factor(s). The monitored factor may be any of several factors that weigh on the operation of the wireless communication system. The synchronization signal itself may vary in how it signals to the neighboring base transceiver station(s) (130) to synchronize with the data to be sent to a given mobile station (110) from its primary base transceiver station (120), and the number of synchronization signals sent over a given time may vary according to the predetermined function of the monitored factor(s).

Abstract: An apparatus and method for determining (410) a quality of channel factor for a base transceiver station (530) of an active set and determining (420) whether the base transceiver station (530) should be assigned to a prefill set at least in part according to a predetermined function of the factor. The predetermined function may include assigning (425) a base transceiver station (530) to the prefill set when the quality of channel factor reaches a predetermined threshold. The quality of channel factor may be determined in various ways including executing (416) an anticipative signal strength algorithm or by monitoring (412) the quality of channel between the mobile station (110) and the base transceiver station (530). Additionally, the primary base transceiver station (120) may be notified (430) of the prefill set such that synchronization signals may be sent (440) to the base transceiver stations of the prefill set.
