    摘要: Methods and devices are provided for implementing two types of sub-channel arrangements. A first type of sub-channel arrangement involves defining a first traffic portion and a second traffic portion of a transmission resource, transmitting broadcast traffic on at least one first antenna of a plurality of antennas in the first traffic portion using a first sub-channelization, transmitting multicast traffic on at least one second antenna of the plurality of antennas, the at least one second antenna being distinct from the at least one first antenna, in the first traffic portion using a second sub-channelization, and transmitting unicast traffic on at least one antenna of the plurality of antennas in the second traffic portion using a third sub-channelization. A second type of sub-channel arrangement involves defining a first traffic portion and a second traffic portion, wherein for a portion of the transmission resource, a portion of the first traffic portion overlaps with a portion of the second traffic portion. In the portion of the transmission resource in which a portion of the first traffic portion overlaps with a portion of the second traffic portion, the channel arrangement involves transmitting broadcast/multicast traffic on at least one first antenna of a plurality of antennas using a first sub-channelization and b) transmitting unicast traffic on at least one second antenna of the plurality of antennas, the at least one second antenna being distinct from the at least one first antenna, using a second sub-channelization. The first, second and third sub-channelizations may be based on either one of or a combination of FDM sub-channelization and TDM sub-channelization.

    摘要: A mobile terminal in a wireless communication network may be one of several modes of operation. When in an idle mode, the mobile terminal may avoid a lengthy random access procedure normally associated with responding to a page from a base station, if the base station includes in the page an indication of a resource that the mobile terminal may utilize when responding to the page. Additionally, the mobile terminal may transmit an efficient location update MAC header to a base station, whether prompted to by a page from the base station or not. Furthermore, without leaving the idle mode or a sleep mode, the mobile terminal may exchange short data burst messages with a base station.
