A method and apparatus for time-based fast positive acknowledgement (ACK)/negative acknowledgement (NACK) reporting (FANR) operation with enhanced general packet radio service 2 uplink (HUGE) are disclosed. A wireless transmit/receive unit (WTRU) configures downlink FANR operation and EGPRS-2 mode uplink transmission not to be in conflict. A modulation and coding scheme (MCS) for the EGPRS-2 mode may be limited to an MCS containing at most two RLC data blocks. Alternatively, three or more piggybacked ACK/NACK (PAN) bits may be used for a time-based FANR operation if an EGPRS-2 mode is configured. Alternatively, at least one PAN bit may indicate an ACK/NACK for a group of RLC data blocks. The number of PAN bits for a time-based FANR operation may be configured by the network. The downlink FANR operation may be dynamically switched between time-based and SSN-based.

Disclosed herein are embodiments for Machine Type Communication (MTC). The techniques disclosed may reduce signaling by transmitting MTC data over control planes and avoiding a full cycle of connection procedures typically required for transmission. MTC data may be directly appended to a control plane message, in addition, in order to reduce the signaling load, a WTRU may autonomously release the connection without being told, by the network. Techniques may be used to indicate a network provider's machine type communication (MTC) capability. The MTC services or capabilities that may be provided by a respective network operator may be communicated to a WTRU.

A method and apparatus for indicating a temporary block flow (TBF) to which a piggybacked acknowledgement/non-acknowledgement (PAN) field is addressed are disclosed. A sequence may be generated from a temporary flow identity (TFI) to which the PAN field is addressed and masked with a PAN check sequence (PCS). A radio block including a PAN field and a masked PCS is transmitted. The PCS may be masked with one of TFIs which is selected in accordance with a rule pre-agreed. A secondary identifier may indicate a TBF to which the PAN field is addressed. A special value may be used to represent all TBFs assigned and a secondary identifier may indicate a TBF to which the PAN field is addressed. A special value on the PAN field may be used for control purposes for indicating an action affecting a group of receiving stations listening to the radio block.
摘要:
A method and an apparatus for indicating a temporary block flow (TBF) to which a piggybacked acknowledgement/non-acknowledgement (PAN) field is addressed. A method and apparatus of performing receive processing to reduce the probability of false acceptance of erroneous PANs are also disclosed. A transmit station generates a PAN check sequence (PCS) and performs a channel coding on a PAN field and the PCS. The transmit station scrambles the encoded bits of the PAN field and the PCS with a TBF-specific scrambling code. Because of the scrambling, the PCS decoding at a receive station will pass if the data block is received by an intended receive station, while the PCS decoding will fail if received by a non-intended receive station. Alternatively, the scrambling may be performed before the channel coding. Alternatively, the transmit station may combine the PAN field and a temporary flow identity (TFI) to generate a PCS.

A method and apparatus of providing a piggybacked positive acknowledgement/negative acknowledgement (ACK/NACK) (PAN) field indicator (PANI) and a polling indicator are disclosed. A combined field of a PANI bit, a relative reserved block period (RRBP) bit and an EGPRS supplementary polling (ES/P) field may indicate a polling scheme and a presence of a PAN field. Alternatively, the presence of the PAN field in the data block may be indicated by using a specific training sequence. Alternatively, a forward error correction (FEC) coding may be performed on the data block including the header, and the presence of the PAN field may be indicated by scrambling the encoded bits corresponding the header with a specific scrambling sequence. Alternatively, a header check sequence (HCS) may be generated and the presence of the PAN field is indicated by mixing a predetermined sequence with the HCS.

A method and apparatus may be used for increasing control channel capacity in Global System for Mobile communications (GSM). In a first method, the Multi-User-Reusing-One-Slot or Voice Services Over Adaptive Multiuser Channels On One Slot (MUROS/VAMOS) concept may be applied to timeslots or bursts carrying a Stand Alone Dedicated Control Channel (SDCCH). In a second method, the control signaling needed to support call setup for voice traffic may be switched over to a MUROS/VAMOS-capable traffic channel as early as possible instead of being handled through the SDCCH. In a third method, the channel coding format of the signaling bursts and/or bursts sent and received on the allocated traffic or SDCCH timeslots or resources may be modified to provide for additional link robustness and to overcome an intrinsic penalty when allowing for two simultaneous wireless transmit/receive units (WTRUs) on a timeslot used for signaling. In a fourth method, a WTRU may notify the GSM network that the WTRU is MUROS/VAMOS capable.

摘要:
A method for accounting for the presence of a piggybacked acknowledgement/negative acknowledgement (PAN) field in reporting a received signal quality for a current wireless transmit/receive unit (WTRU) is disclosed. A determination is made whether a received radio block is intended for the current WTRU. The received signal quality of the radio block is measured if the radio block is intended for the current WTRU. Bits from the PAN field are included in determining the received signal quality of the radio block based on a preconfigured option. The radio block measurement is included in a measurement report if a data header of the radio block is not addressed to the current WTRU but the PAN field is addressed to the current WTRU.

摘要:
A method, wireless transmit/receive unit (WTRU), and base station for access network interworking. Temporary identity mapping rules are defined for use during access network reselection. Mapping rules for tracking area identity, routing area identity, temporary mobile subscriber identity (TMSI), packet TMSI, and S-TMSI identity are used when reselecting UTRAN, E-UTRAN, and GERAN access networks. Depending upon access network support, a WTRU may indicate a type of identity (TMSI, P-TMSI, or S-TMSI) that is included in an access network reselection request.
