摘要： User Equipments (UEs) can be adapted to enter into a lower RRC state from a higher RRC state, and search for one or more layers of higher priority within a predetermined period of time upon entering into the lower RRC state. According to at least one aspect, this search for one or more layers of higher priority may be performed irrespective of RF quality of a current serving cell. According to at least another aspect, this search for one or more layers of higher priority may be conducted within the predetermined period of time if a wait period has elapsed since the UE camped on the current serving cell. If the wait period has not elapsed since camping on the current serving cell, the search for one or more layers of higher priority may be performed within the predetermined period of time following a duration of the wait period.

摘要： Wireless user equipment (UE) operating in a wireless communication system may operate in a state, for example, the CELL_FACH state in UMTS, that does not allow for soft handoff from one cell to another. This inability to engage in soft handover may lead to intercell interference at a non-serving cell when the UE transmits on its uplink in close proximity to the non-serving cell. Therefore, provided in the present disclosure is method of wireless communication, which includes receiving a neighbor cell identification set indicating one or more neighbor cells, receiving a relative grant channel resource index corresponding to a relative grant channel shared by at least one of the one or more neighbor cells, detecting intercell interference associated with a user equipment (UE) in the one or more neighbor cells, and transmitting a non-serving relative grant message to the UE on the relative grant channel.

摘要： A base station (e.g., a Node B in a Multi-Point HSDPA network) calculates an amount of data to request from a network node (e.g., a radio network controller or RNC). As a part of the algorithm utilized, a length of a queue at the Node B for buffering the flow may be dynamically adjusted in an effort to optimize the trade-off between buffer underrun and skew. Further, a network node (e.g., the RNC) responds to Node B flow control requests. Here, the RNC may determine the amount of data to send to the Node B in response to the flow control message from the Node B, and may send the data to the Node B. In various aspects of the present disclosure involving a Multi-Point HSDPA system, the flow control algorithm at the RNC coordinates packet flow to the primary serving cell and the secondary serving cell for the UE.

摘要： Systems and methodologies are described that facilitate increasing throughput in a time-division duplexed CDMA wireless communication environment. A set of orthogonal Walsh code sequences can be assigned to a first group of users in a network sector, and a duplicate set of orthogonal Walsh code sequences can be assigned to at least a second group of users in the sector. A number of receive antennas equal or greater than to the number of duplicate code sets being assigned can be deployed to linearly scale sector capacity to meet user demand. Additionally, user devices employing duplicate Walsh code sequence assignments at a base station serving the sector can be distinguished from each other, and timing offsets between such users can be enforced to mitigate any jamming effect at the base station receiver. Still furthermore, user device channel requirements in the sector can be continuously evaluated and an appropriate number of antennas can be dynamically deployed to provide scalable service to all such user devices.

摘要： A method for load control in uplink interference cancellation systems with soft decision is disclosed. It is determined whether interference is to be cancelled from a received signal based on a packet size of the received signal. If the signal is to be cancelled, a maximal correlation factor between an interfering portion and a useful portion of the received signal is determined based on a transport block size of the received signal. If the signal is to be cancelled, a reduced target load for a base station is also determined based on the maximal correlation factor. If the signal is to be cancelled, uplink transmit power for one or more wireless communication devices is adjusted based on the reduced target load.
