摘要： Various embodiments are described to address the need for an apparatus and method for providing uplink communication resources that reduce some of the existing delays in acquiring these resources. In general, they may involve a RAN (121) transmitting data to a remote unit (101) via a downlink communication resource. After transmitting the data and with no additional data ready for transmission, the RAN begins transmitting assignment messages to the remote unit for an uplink resource. However, these assignment messages are not transmitted in response to uplink resource requests from the remote unit. In addition to or alternatively, the RAN detects a regular pattern in uplink activity of the remote unit and then begins predicting, based on the pattern, when the remote unit will next need an uplink resource. When the remote unit is predicted to need an uplink resource, the RAN transmits an assignment message to the remote unit.

摘要： A method and apparatus for that provides a re-entry procedure following a radio frequency outage in a wireless communication network is disclosed. The method includes providing (204) a entity identification for a base station (102-106) or a paging controller (108) to a mobile station (110) during initial entry of the mobile station to a wireless communication network. The method also includes storing (206) mobile station context information at an entity corresponding to the entity identification. After a radio frequency outage occurs after the initial entry of the mobile station into the network, a notification is sent (218) that indicates that the mobile station is re-entering the wireless communication network. Based on the notification that there has been a radio frequency outage, the mobile station context information is obtained (220) to assist the mobile station to re-enter the wireless communication network.

摘要： A method, base station, and wireless communication system provide seamless mobility in a time division duplex system. The method includes determining a mobility capability of the wireless communication device (104). In response to determining that the mobility capability of the wireless communication device (104) may involve a network address change for a new sub-network (204), an identification of at least one neighboring base station (208) is provided to the wireless communication device (104) that the wireless communication can select to be handed into.

摘要： A method is described for providing Hybrid Automatic Repeat Request (HARQ) transmission feedback to a higher layer protocol in a communication system. The method includes a step of detecting HARQ retransmissions in a first layer protocol. This can be used to determine a HARQ failure or an HARQ ACK after a delay of some retransmissions. A next step includes providing feedback information about the detecting step from the first layer protocol to a higher layer protocol. A next step includes instituting corrections at the higher layer protocol, in response to the information transferred from the first layer protocol. These corrections can include immediate retransmission of those bursts of a HARQ failure, or correcting timers to match the delay of eventually ACK'ed data.
