Abstract: The present invention is related to a method and system for transferring wireless transmit/receive unit (WTRU)-specific information to support enhanced uplink (EU) operation in a wireless communication system. A radio network controller (RNC) obtains WTRU-specific information, and transfers the WTRU-specific information to the Node-Bs. Each Node-B is configured to schedule uplink transmissions from a WTRU and utilizes the WTRU-specific information in operation of EU transmissions.

Abstract: Techniques for transmitting synchronization signals to assist user equipments (UEs) perform cell searches are described. In one design, a base station for a cell may generate and transmit a primary synchronization signal and a secondary synchronization signal, which may be used by the UEs for initial cell search at power up. The base station may also generate and transmit one or more beacon signals, which may be used by the UEs for neighbor cell search to detect for neighbor cells. The number of beacon signals to transmit and the set of subcarriers usable for each beacon signal may be determined based on the system bandwidth. Each beacon signal may be mapped to one subcarrier in the set of subcarriers in each beacon symbol period. This one subcarrier may be determined based on a beacon hopping pattern or a beacon code and may be dependent on a cell identifier (ID).

Abstract: Tones within a channel can be selected randomly and/or based on orthogonal tone selection. Random selection can include selecting tones randomly from a fixed set, which is referred to as channelized tone selection. Channelized tone selection can be chosen if a critical tone exists. Random selection can also include selecting resources randomly from the total number of resources available, which is referred to as non-channelized tone selection. Orthogonal tone selection can be chosen to mitigate the probability of receiver desensitization and/or to attempt to mitigate interference.

Abstract: A scheduled data communication system of an access node and terminal supports recurring communications of small data amounts such as Voice over IP (VoIP). In order to make error checking more robust in a random access response (RAR), such as for semi-persistent scheduling (SPS) for VoIP, a portion of a grant or assignment payload has a constraint imposed that can be verified as a condition precedent to determining a valid grant or assignment rather than only relying upon a validity check field, such as a cyclic redundancy check (CRC). Thereby, incorrect validation of a grant or assignment is avoided for dynamic scheduling or for semi-persistent scheduling, the latter causing a persistent error.

Abstract: Two User Equipment (UE) operate in a Near Companion Mode (NCM), in which a monitoring UE (MUE) monitors an uplink transmission opportunity granted to its companion UE (CUE) on a shared uplink channel. If the CUE does not begin transmitting within a predetermined portion of its transmission opportunity, the MUE may utilize the transmission opportunity to transmit an uplink data packet. In one embodiment, where the CUE does not have data to transmit, it may transmit a predetermined pattern at the beginning of its transmission opportunity, to indicate to the MUE that the transmission opportunity is available. The MUE may transmit an NCM radio block using the entire symbol space associated with the last three of four bursts allocated to the CUE, or using a newly defined NCM format comprising four abbreviated bursts, using only a portion of the symbol space associated with the four bursts corresponding to the transmission opportunity allocated to the CUE.

Abstract: Systems and methodologies are described that facilitate sending a power control command in a wireless communication environment. A base station can send a power control command to a UE through resource elements reserved for at least one Physical Downlink Control Channel (PDCCH). Thus, the power control command can be punctured into a control channel element (CCE) reserved for the at least one PDCCH. Further, the base station can convey an indicator that specifies the resource elements reserved for the at least one PDCCH used for sending the power control command to the UE. Moreover, the base station can use a structure similar to a conventional (e.g., Release 8, . . . ) PHICH structure for sending the power control command using the resource elements reserved for the at least one PDCCH. For example, the power control command can be spread using one or more Walsh codes assigned to the UE.

Abstract: The present invention discloses a network node (100) for multi-user scheduling involving retransmission. The network node comprises a receiver (110) adapted to receive channel quality indicator (CQI) report from a user equipment (UE), an adjuster (120) adapted to adjust signal to interference and noise ratio (SINR) derived from the CQI report to obtain SINR for retransmission, a combiner (130) adapted to combine SINR for initial transmission and SINR for one or a plurality of retransmission to obtain effective SINR, and a scheduler (140) adapted to perform multi-user scheduling on the basis of priority metric derived from the effective SINR. The present invention improves multi-user scheduling by taking HARQ combining gain into account. Instantaneous throughput as well as priority metric can be accurately measured, because SINR from not only channel quality (e.g. CQI) but also HARQ processing gain are both included.

The invention suggests a mechanism for triggering channel quality feedback from a terminal where the downlink control signaling overhead for the selection of component carrier(s) to be reported on is minimized.

In case the CQI request flag is set at least one further bit of the dedicated control information is interpreted as information indicative of the one or more component carriers available for downlink transmission to the terminal and the terminal is providing channel quality feedback on the channel quality experienced on the indicated component carrier or component carriers.

Abstract: A method for assigning acknowledgement (ACK) channels to a user is used to feed back ACKs of a plurality of downlink sub-frames in one uplink sub-frame. According to the method, reserved ACK channels are divided into blocks according to the number of downlink sub-frames; each downlink sub-frame corresponds to one block; each block is divided into several sub-blocks; control channel element (CCE) sets within the same sub-frame are respectively mapped to different sub-blocks; and the ACK channels are assigned to the downlink sub-frames according to a sequence of increasing a mapping label d first and then increasing a sub-block label m. Thus, more unused ACK channels can be released to form resource blocks (RBs) for transmission on other channels, for example, for PUSCH transmission. Other methods for assigning ACK channels to a user, a device for assigning ACK channels to a user, and a communication system are further provided.

Abstract: An on-vehicle device sends an allocation request for a wireless resource to a roadside device. The roadside device, in response to receiving this allocation request, allocates a roadside-vehicle resource that is a wireless resource for roadside-vehicle communication with the on-vehicle device, and an inter-vehicle resource that is a wireless resource for inter-vehicle communication between on-vehicle devices; and sends the allocation information to the on-vehicle device. The on-vehicle device carries out roadside-vehicle communication with the roadside device using the roadside-vehicle resource identified with the allocation information received from the roadside device, and carries out inter-vehicle communication with other on-vehicle devices using the inter-vehicle resource identified with the allocation information. Thereby, roadside-vehicle communication and inter-vehicle communication can be achieved with higher utilization of wireless resources while avoiding the hidden terminal problem.

Abstract: A reproduction speed of an application being executed is controlled with changing an upper limit of accumulation of a jitter buffer based on a radio state during communication by a first wireless communication network. If it is determined to start handover preparation from the first wireless communication network to a second wireless communication network, a preparation time before handover and an absolute delay time of each of the first wireless communication network and the second wireless communication network are obtained from the handover control unit.
