    摘要： A method in a wireless communication device and an apparatus, such as a wireless communication device, for reporting a channel quality indication to non-serving cells. The device can operate on a shared channel on a serving cell. The device can send a channel quality indicator message on a medium access control layer to multiple candidate cells in an active set of cells. The device can then switch from the serving cell to a new serving cell from the multiple candidate cells based on information in the channel quality indicator message.

    摘要： A method for controlling diversity receivers in a wireless communication device includes the steps of: determining if the wireless communication device is experiencing poor coverage (220), using a first receiver and a second receiver for diversity (230) if the wireless communication device is experiencing poor coverage, and using the second receiver for scanning (240) if the wireless communication device is not experiencing poor coverage. Thus, diversity can be used when needed to improve reception. Both receivers, however, can be used in a non-diversity mode to reduce current drain or to speed up channel acquisition when coverage is not poor.

    摘要： In a 3rd Generation Partnership Project, 3GPP, communication system a base station comprises a scheduler allocating communication resource of at least one of a Physical Uplink Shared CHannel, PUSCH, and a Physical Downlink Shared CHannel, PDSCH to a User Equipment (UE). The scheduling may either be a dynamic scheduling wherein a resource allocation for a single frame is provided to the UE or a persistent scheduling wherein a resource allocation for a plurality of frames is provided to the UE. A resource allocator assigns resource of a Physical Uplink Control CHannel, PUCCH, to the UE dependent on whether dynamic scheduling or persistent scheduling is performed by the scheduler for the UE. The UE transmits uplink control data on a physical uplink channel which is selected as the PUCCH or the PUSCH in response to whether persistent scheduling is used for the UE. The invention allows e.g. reduced PUCCH loading.

    摘要： A communication is provided that schedules both Distributed Virtual Resource Blocks (DVRB) and Localized Virtual Resource Blocks (LVRB) in a same frequency channel, thereby obtaining the benefits of frequency selective scheduling while minimizing the uplink feedback overhead. In one embodiment of the invention, the communication system assigns one or more downlink Physical Resource Blocks (PRBs) of multiple downlink Physical Resource Blocks (PRBs) to each user equipment (UE) given an LVRB to produce at least one reserved PRB and multiple non-reserved PRBs and assigns a part of each PRB of the multiple non-reserved PRBs to a UE given a DVRB. In another embodiment of the invention, the communication system assigns PRBs pre-reserved for localized transmission to UEs scheduled for LVRBs and assigns parts of multiple PRBs pre-reserved for distributed transmission to each UE given a DVRB.

    摘要： Various embodiments are described which can serve to mitigate interference between the control channel signaling of adjacent sectors/cells. Potentially, these techniques may have the benefit of reducing the system resource drain caused by control channels, particularly control channels in high frequency-reuse, OFDMA systems. A transmitting device (101) transmits primary control channel information to a plurality of user devices (102). The primary control channel information includes an indication that a first OFDMA resource region (e.g., 320 or 330) is assigned to at least one user device of the plurality of user devices. The transmitting device correspondingly transmits secondary control channel information to the at least one user device using the first OFDMA resource region.

    摘要： To address the need for an apparatus and method for handoff from a cellular wireless network to a non-cellular wireless network (WLAN, e.g.), the present application describes an access gateway (214) and a dual mode mobile station (201) that enable such handoffs. Dual mode MSs can determine when a handoff to a non-cellular network is preferred and request a handin (302) from the non-cellular network. The access gateway provides information to the MS (304) so that it can initiate a handoff through the serving cellular network. Triggering handoffs in this manner, allows cellular networks to handle handoffs to non-cellular networks in much the same way they handle inter-MSC handoffs today, i.e., source initiated.
