A wireless transmit receive unit (WTRU) configured to indicate REDHOT and HUGE multi-slot capability to a network. The REDHOT multi-slot capability is included in a MS Classmark 3 information element and a MS Radio Access Capability information element. In another embodiment, DLDC operation in an evolved GERAN system includes both single carrier and dual carrier modes. Monitoring in single carrier mode reduces battery consumption. Various techniques for enabling dual carrier mode are disclosed.

A method and apparatus are disclosed for wireless transmission using two or more pulse shaping filters. Wireless transmit/receive units (WTRUs) and network entities are capable of utilizing a narrow band pulse shaping filter, a wideband pulse shaping filter, or both. The network entity and/or the WTRU select a pulse shaping filter to be used and transmits the selection by means of signaling. The signaling may be performed through layer 2/3 messages or by using non-access stratum (NAS) signaling messages.

Piggybacked acknowledgement/non-acknowledgement (PAN) bits in unreliable bit positions of a modulated symbol are swapped with data bits located in more reliable bit positions. In addition, a power offset value may be applied to the symbols containing the PAN bits.

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.

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.

Embodiments contemplate techniques and devices for allocating IP addresses for MTC devices, transmitting and receiving SMS using the allocated IP addresses. The MTC device may be allocated with an IP address without activating a packet data protocol (PDP) context. In addition, after the IP address has been allocated, SMS messages may be transmitted from and to MTC devices using the IP address.
摘要:
A method and apparatus to improve the quality of control signaling based on signaling messages controlling speech or data transmission over an air interface between at least two Multi-User-Reusing-One-Slot/Voice Services Over Adaptive Multiuser Channels On One Slot (MUROS/VAMOS) capable wireless transmit/receive units (WTRUs). The WTRUs communicate with each other at the physical layer via signaling messages transmitted in control channels such as Slow Associated Control Channel (SACCH) and Fast Associated Control Channel (FACCH). Speech services are provided simultaneously over the same physical channel, and the Timing Advance (TA) and Power Command (PC) parameters of a WTRU are multiplexed in several occurrences of the SACCH or FACCH to increase the number of channel bits available for channel coding.
摘要:
A method and apparatus for indicating a temporary block flow (TBF) to which a piggybacked acknowledgement/non-acknowledgement (PAN) field is addressed. A PAN check sequence (PCS) is created, for example using a cyclic redundancy check (CRC) encoding. The PCS is masked with a temporary flow identity (TFI) assigned to a TBF or a mask generated based on the TFI. A data block including the PAN field and the masked PCS is then processed for transmission. The mask may be generated by converting the TFI using an (M, N) code, M being not greater than the number of bits of the PCS and N being the number of bits of the TFI. With this scheme, a TFI may be transmitted in a PAN field without using explicit bits to identify the TBF.

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.
