Abstract: A sequence of codes are provided for potential assignment to a user in a wireless hybrid time division multiple access (TDMA)/code division multiple access (CDMA) communication system. At least one timeslot is selected to support the communication. For each selected timeslot, at least one code is selected. If more than one code is selected, the selected codes are consecutive in the provided codes sequence. For at least one of the selected timeslots, an identifier of a first and last code of the selected consecutive codes is signaled. The user receives the signaled identifier and uses the selected consecutive codes, as identified, to support the communication.

Abstract: A method of using a user equipment (UE) in a wireless time division duplex communication system. The system uses code division multiple access and communicates using communication bursts. Each communication burst has a unique channelization code and a midamble code which is uniquely related to the channelization code, each such midamble code being uniquely related to one or more channelization code. The UE receives communication bursts and detects each midamble code in a received communication burst. The UE determines the channelization codes related to each detected midamble based on a mapping of midamble codes to related channelization codes. The UE detects channelization codes in the received communication burst from among the determined channelization codes. The UE recovers data from the received communication burst based on in part the detected channelization codes. Where all midamble codes are uniquely related to one channelization code, the UE recovers data from the received communication burst based on in part the determined channelization codes without the additional channelization code detection step.

Abstract: A user equipment (UE) for a wireless time division duplex communication system which uses code division multiple access. The system communicates using communication bursts, each communication burst having a unique channelization code and a midamble code which is uniquely related to the channelization code. Each such midamble code being uniquely related to one or more channelization code. The UE has an antenna for receiving communication bursts and a midamble detector which detects each midamble code in a received communication burst. A logic block determines the channelization codes related to each detected midamble based on a mapping of midamble codes to related channelization codes. A channelization code detector detects channelization codes in the received communication burst from among channelization codes determined by said logic block. A multiuser detection device recovers data from the received communication burst based on in part the channelization codes detected by said channelization code detector. Where all midamble codes are uniquely related to one channelization code, the multiuser detection device recovers data from the received communication burst based on in part the determined channelization codes without the need for the channelization code detector.

Abstract: A method and strategy for transport format combination (TFC) selection and related algorithms in wireless communications. The method provides procedures used by the MAC layer in both the UE and the RNC to schedule data transmission. In the inventive method, each time the maximum transmit power is reached in a time slot, the physical layer will send a notification to the MAC layer, including the time slot number where maximum power was reached. The invention provides a low cost method and algorithm avoiding the need for the MAC to determine the power needed by each TFC in each time slot.

Abstract: A wireless digital communication method for a plurality of user equipment mobile terminals (UEs) to communicate with a base station. Adaptive modulation and coding (AM&C) is used to achieve improved radio resource utilization and provide optimum data rates for user services. Blocks of downlink (DL) data are received by the base station which requests downlink DL channel quality measurements only from those mobile terminals (UEs) with pending downlink transmissions. The UEs respond to the request by measuring and reporting DL channel quality to the base station, which then allocates resources such that the UEs will make best use of radio resources. The base station notifies the UEs of the physical channel allocation indicating the modulation/coding rate and allocated slots followed by transmission of blocks of downlink data which are transmitted to the UEs.

Abstract: The present invention relates to efficient recovery of High Speed Downlink Packet Access (HSDPA) data following handover. The present invention discloses a method and system for the UE to perform a series of actions in order to reduce the latency and potentially prevent loss of PDU transmission during the serving HS-DSCH cell change procedure. A new criterion is introduced for UE generation of the status report of RLC PDU. The UE generates status report of the PDUs as soon as possible following notification of the HS-DSCH cell change indicated by the RRC procedure to more efficiently recover source Node B buffered data. PDU status may be signaled for each AM RLC instance associated with the HS-DSCH transport channel. Furthermore, upon Inter Node B serving HS-DSCH cell change the SRNC may wait for PDU status report before initiating transmission of new data in target cell.

Abstract translation: 本发明涉及切换后的高速下行链路分组接入（HSDPA）数据的有效恢复。 本发明公开了一种用于UE执行一系列动作的方法和系统，以便在服务HS-DSCH小区改变过程期间减少等待时间并潜在地防止PDU传输的丢失。 引入了用于UE生成RLC PDU的状态报告的新标准。 在通过RRC过程指示的HS-DSCH小区改变之后，UE将尽快生成PDU的状态报告，以更有效地恢复源节点B缓冲的数据。 可以针对与HS-DSCH传输信道相关联的每个AM RLC实例发信号通知PDU状态。 此外，在服务HS-DSCH小区改变的节点B之间，SRNC可以在开始发送目标小区中的新数据之前等待PDU状态报告。
