  • Publication number: 20110267955
    Abstract: A network learns a user equipment's capability information whether the UE is capable of simultaneous and independent operation in multiple component carriers. The network configures a monitoring (e.g., discontinuous reception, RSRP/RSRQ measurements, PDCCH reception) pattern for each of multiple component carriers CCs that are configured for the UE in dependence on the received capability information. The capability information derives from the UE's RF layout; if the capability information says the UE is capable of such simultaneous and independent operation the network can assign for the CCs different monitoring patterns that are independent of one another and the UE will have no gaps where it cannot take or send a measurement. This knowledge is particularly useful if the CCs are frequency non-contiguous with one another. If the capability information says the UE is not so capable, the network must assign monitoring patterns to that UE for all its configured CCs that are not independent of one another.

  • Patent number: 7916675
    Abstract: A method, terminal device, network element, system and computer program product for controlling discontinuous reception or transmission at a terminal device of a communication network are disclosed. A regular discontinuous reception or transmission cycle of a regular discontinuous reception or transmission scheme is set by using a first control layer, and in addition thereto a shorter temporary discontinuous reception or transmission cycle of an interim discontinuous reception or transmission scheme can be set by using a second control layer. This arrangement provides long discontinuous reception or transmission cycles for power consumption improvements while at the same time ensuring that the network can easily and flexibly shorten these cycles for increased data throughput, if needed.

  • Publication number: 20100290509
    Abstract: Systems and methods for providing half duplex user equipment in a packet based radio frequency signaling communication system. User equipment with half duplex receiver and half duplex transmitter on IC providing a transceiver capability performs a cycle of receiving downlink messages for a predetermined number of sub frames, shifting to a transmit mode, transmitting uplink messages for the predetermined number of sub frames, shifting to a receive mode, and repeating the cycle of half duplex sub frames. A discontinuous reception function performs a DRX protocol wherein power is reduced to the transceiver for a period of time. A determination is made at the end of the discontinuous reception period to see if the half duplex cycle is at an uplink sub frame; if so, the end of the discontinuous reception is shifted by the user equipment to a downlink sub frame by adding a delay.

  • Publication number: 20100290427
    Abstract: A method is described which provides a synchronized HO of a mobile device. The method includes receiving a HO command. A determination is made of whether the HO command includes an indication of UL resource allocations. A C-RNTI is waited for in DL signaling if the HO command does not include the indication of UL resource allocations. If the HO command includes the indication of UL resource allocations, transmitting occurs based on the UL resource allocations. The method may be performed as a result of execution of computer program instructions stored in a computer readable memory medium. An apparatus is also described.

  • Publication number: 20100284360
    Abstract: A user equipment (UE) receives a first dynamic resource allocation on a first channel (PDCCH), then sends data according to the first resource allocation. During a time at which an ACK/NACK for the sent data is scheduled to occur on a second channel (PHICH), the UE is engaging in an activity that takes priority over the ACK/NACK. The UE then receives a second dynamic resource allocation on the first channel and determines the ACK/NACK for the sent data from the second dynamic resource allocation. The determining can be direct, as in receiving a zero-valued resource allocation; or it may be indirect as in mapping the second dynamic resource allocation to the second channel and receiving the acknowledgement on the second channel after that mapping. Also detailed are similar mirror actions from the Node B's perspective, as well as apparatus, methods, and embodied computer programs.

  • Publication number: 20100279715
    Abstract: A network sends an indication of discontinuous reception period (ldle_Mode_DRX_Period) and an indication of number of paging groups (Paging_Group_Count). Paging occasions for a user equipment are determined by a predetermined formula. One exemplary formula is SFN mod IDLE_Mode_DRX_Period=(IDLE_Mode_DRX_Period div Paging_Group_Count)*(ID) mod (Paging_Group_Count); where SFN is system frame number and ID is the identifier of the user equipment, which can be IMSI or some value derived from IMSI. The UE's temporary ID is sent during a determined paging occasion, which maps to a paging channel on which the page is sent. Options for restricting the paging occasion to less than a frame, and for offsetting the paging occasions from that of the above formula are detailed.
