摘要： Techniques for synchronization of stored service parameters are disclosed. In one aspect, a configuration identifier is transmitted from a mobile station to a base station, and compared with an identifier generated in the base station. If the identifiers match, the configuration is used for communication. In another aspect, the identifier is generated by selecting an identifier associated with a configuration from a configuration table. In yet another aspect, the identifier is generated by computing a cyclic redundancy check (CRC) of the configuration. Various other aspects are also presented. These aspects have the benefit of preventing attempted use of unsynchronized stored service parameters and associated call setup failures and subsequent renegotiation, with the net effect of reducing call setup time and more efficient use of system resources.

摘要： A delta configuration is transmitted to a UE requesting a handover wherein the delta configuration details changes that are required for the current UE configuration in order to execute the handover. The handover is initiated via a measurement report transmitted to a currently serving source eNode B from the UE. The measurement report can comprise one or more of current radio conditions, current UE configuration or a preferred target eNode B if the handover is a inter eNode B handover. In a inter eNB handover, the current UE configuration is forwarded to the preferred target eNode B by the source eNode B. The target eNode B generates the delta configuration and transmits it to the source eNode B in a transparent container which is subsequently forwarded to the UE.

摘要： Methods and apparatus are presented for implementing an improved Control-Hold Mode that reduces the load of the reverse link and reduces the battery consumption of remote stations. While a remote station is in the improved Control-Hold Mode, the circuitry that monitors the forward packet data channels and the associated control channels are turned off. Since the forward packet data channels and their associated control channels are not monitored, the operations of the reverse channels can be gated off to predetermined duty cycles, or set on intermittent transmission modes, or shut down completely. Transitions from the Control-Hold Mode to the Active Mode can be initiated by the remote station or by a base station. When a transition is initiated by a remote station, the remote station transmits a signaling message to a serving base station and then starts operating the feedback channels before actually receiving forward link signals.

摘要： Systems and methodologies are described that facilitate compressing headers for relay nodes. In particular, a robust header compression (RoHC) profile can be defined for general packet radio service (GPRS) tunneling protocol (GTP) headers. Upon receiving a packet with one or more GTP headers, an access point or relay node can determine whether the one or more GTP headers are compressible and can apply the RoHC profile to compress the one or more GTP headers. In addition, the packet can include a baseheader encapsulated by the one or more GTP headers, which can also be compressed according to a RoHC profile specific to the baseheader. Moreover, RoHC compressed headers can be decompressed according to the GTP RoHC profile.

摘要： Systems and methodologies are described herein that facilitate techniques for managing respective original transmissions and re-transmissions of information within a wireless communication system. Various mechanisms are described herein for processing a new data indicator (NDI) associated with respective transmissions conducted for one or more Hybrid Automatic Repeat Request (HARQ) processes. For example, for a HARQ process shared between distinct scheduling schemes, an NDI associated with a latter transmission can be regarded as toggled irrespective of the value of the NDI upon recognizing that a utilized scheduling scheme (e.g., as indicated via a radio network temporary identifier (RNTI) or the like) has changed between successive transmissions (e.g., from semi-persistent scheduling to dynamic scheduling), thereby allowing processing of the latter transmission as a transmission of new data. As additionally described herein, various techniques are described herein for NDI processing in the case of uplink grant and downlink assignment transmission.

A radio link control transmitter can poll a receiver to obtain a report regarding the status of a set of data packets, and the polls can be sent in-band with a data packet. The receiver can determine to wait before sending the status report based on one or more characteristics of the received data packets.

摘要： Systems and methodologies are described that facilitate utilizing timers in conjunction with transmitting buffer status reports (BSR). A prohibit timer can be utilized to determine when BSRs can be transmitted to an eNB. The prohibit timer can be initialized or restarted upon transmitting a BSR to an eNB. A BSR retransmit timer can be used to determine when to retransmit a BSR. The BSR retransmit timer can be initialized upon transmitting a BSR to an eNB and restarted each time an uplink resource allocation is received from the eNB. Once the timer expires, if an uplink transmission buffer contains data (e.g., size>0), the BSR can be retransmitted to the eNB. Control data feedback can additionally be used to determine when to retransmit the BSR. In addition, in either case, the timer duration values can be provided by the eNB.

摘要： A data packet communication system employs radio link control (RLC) transmission between a transmitter and a receiver with an Automatic Repeat Request (ARQ) arrangement whereby polling of the receiver is accomplished with reduced amount of redundantly transmitted data, such as between an access node and terminal. Upon a polling event, such as emptying of a transmission buffer of the transmitter, expiration of a polling timer, or reaching a radio link control (RLC) protocol data units (PDUs) count threshold, the transmitter sends a polling command to the receiver. This polling command is smaller than any of the RLC PDUs, which are conventionally resent with a polling bit set to evoke a STATUS PDU from the receiver. With evolving communication standards tending toward larger PDUs, such as in excess of a kilobyte for HSPA+ (High-Speed Packet Access Evolution) and 3GPP LTE (Long Term Evolution), this inefficiency can be of increasing impact.
