PROBLEM TO BE SOLVED: To provide a digital wireless communication system for reduction of scheduling and ARQ delay. SOLUTION: An up-link transmission scheduling method includes a step for receiving scheduling information 402 from a mobile station 1014 with a base station 301, 303, and 304 in an active set. The scheduling information has at least one of the queue status and electrical power status of the mobile station. The method also includes a step for determining up-link channel scheduling assignment 418 with the base station in the active set by utilizing the scheduling information and at least any one of a base station interfrometer amount and link quality, which correspond to the mobile station. The method still further includes steps for transmitting up-link channel scheduling assignment 418 containing a maximum power margin target with the base station in the active set and for receiving a selection instruction 416 of the modulated encoding system of up-link transmission based on the maximum power margin target from the mobile station with the base station in the active set.

PROBLEM TO BE SOLVED: To identify an incoming call from a person with whom a user frequently makes contact. SOLUTION: A communication device (100) includes a transceiver (115) for receiving a call, a received calls memory (145) for storing call sources (300) and for storing an associated call count (315) for each call source (310), and a processor (120). The processor (120) is programmed to: identify a call source of a received call, generate a command signal to an alert circuit (130), identify a unique alert associated with the call count, and increment the call count. The communication device (100) further includes the alert circuit (130) for alerting using the unique alert identified by the processor (120). COPYRIGHT: (C)2011,JPO&INPIT

PROBLEM TO BE SOLVED: To provide a wireless communication system and method in which high speed uplink packet access to a base station is made from user equipment. SOLUTION: Each user equipment 128, 130 and base station 114, 116, 118, 120 includes a transmitter, a receiver, and a controller. The user equipment 128, 130 transmits data packets to the base station 114, 116, 118, 120. The base station transmits control information corresponding to the data packets to the user equipment 128, 130. The control information includes at least one channelization code allocated to the user equipment 128, 130. The controller minimizes the channelization code per scheduling active set cell to be monitored by the user equipment based on the channelization code in response to handoff and/or transferring to an active channel state.

PROBLEM TO BE SOLVED: To prevent the misoperation of a slider key when a user opens/closes a slide part. SOLUTION: Disclosed are methods in a slider form factor device, and slider form factor devices, for ignoring a key depression when there is a change in the position of a first housing relative to a second housing that occurs between the key depression and the release of the key depression. The method may include detecting a key depression of the first housing, detecting a change in the position of the first housing relative to the second housing, and detecting a release of the key depression. The method may further include ignoring the key depression when there is a change in the position of the first housing relative to the second housing that occurs between the key depression and the release of the key depression.

Abstract:
PROBLEM TO BE SOLVED: To provide a method for transmitting primary and secondary synchronization channels, and to provide an apparatus thereof. SOLUTION: During operation, a transmitter transmits a primary synchronization channel (P-SCH) in a subframe and a secondary synchronization channel (S-SCH) in the subframe. The S-SCH is modulated by a complex exponential wave and scrambled by a scrambling code. In a certain embodiment, the P-SCH comprises a GCL sequence or a Zadoff-Chu sequence, and the scrambling code uses the GCL sequence index of the P-SCH. COPYRIGHT: (C)2008,JPO&INPIT
