摘要： Multicast broadcast service (MBS) transmission in a multiple-input-multiple- output (MIMO) communication being transmitted using one of three modes, a single-layer mode, a spatial multiplexing (SM) mode and a hierarchical mode. In the hierarchical mode, lower quality data is transmitted over a first MIMO layer and enhancement data is transmitted over a second MIMO layer. A receiving device may only successfully receive the lower quality data or may successfully receive the enhancement data to enhance it with. The transmission scheme used, including the mode used, may be selectable, and may be selected based on feedback.

摘要： Transmission of uplink control message for a wireless system. The uplink control message may be encoded according to one of multiple possible schemes. The choice of encoding scheme may be made based on the control message size and/or based on the available transmission resources and/or based on the detection scheme used on the receiving end. A modulation scheme may also be selected based on such factors. CDM may be used for certain control messages. Block code encoding, such as Reed-Muller encoding may be used for certain control messages. Different transmission resources may be allocated for different control message uses. The encoding specifics may be selected to obtain a certain hamming distance and/or size of the encoded message or based on other factors.

摘要： Methods and systems are described that are suitable for channelization, m particular, but not limited to, the IEEE 80216. m telecommunications standard. For a time-frequency resource, physical sub-carriers for each of one or more zones in the time-frequency resource are assigned to one or more zones having a respective type of transmission. At least one zone is allocated for a type of transmission using localized sub-carriers. The physical sub-carriers assigned to each zone are permuted to map to logical sub-carriers- Groups of resource blocks are formed, in which each resource block includes at least one logical sub-carrier for each of the one or more zones. The information defining the groups of resource blocks for each of the one or more zones can then be transmitted to a user. The information may be in the form of a zone configuration index.

摘要： An uplink power control scheme for a wireless communication system is provided. In general, a subscribing station is located within a serving sector of a cell served by a base station in a wireless communication network. In one embodiment, the subscribing station obtains interference parameters for one or more neighboring sectors of the serving sector of the subscribing station. In this embodiment, the interference parameters are interference thresholds. The subscribing station then controls a maximum transmit power, and thus a power headroom, of the subscribing station based on the interference thresholds for the one or more neighboring sectors.

摘要： To effectively and efficiently provide control information, a broadcast pointer channel (BPCH) may be used to identify the type and perhaps relative location of control information that is being provided in a given frame structure, such as a sub-frame, frame, or superframe. A sub-frame (or like framing entity, such a frame or superframe) may have a BPCH and a corresponding system control information segment in which control information may reside. The system control information segment may have any number of control information blocks, wherein each control information block that is present may correspond to a particular type of control information. The BPCH is used to identify the type of control information that is present in a corresponding system control information segment, and if needed or desired, the relative locations of the various control information.

摘要： In wireless communications systems, the Base Station Controller (BSC) (241) and Base Transceiver Stations (BTSs) (211, 213) have schedulers (243, 215) which schedule soft handoff (SHO) users (221) and non-soft handoff (NSHO) users (223, 225) regardless of delay sensitive users. The BSC's scheduler (243) prioritizes the SHO users (221) and calculates the available capacity at each sector. Then, with assigned data rates according to the priority, the available capacity is updated by the BSC's scheduler (243). The BTS's scheduler (215) calculates the available capacity at the sector and with assigned data rates according to the priority of the NSHO users (223, 225), the available capacity is updated. Based on the updated available capacity packet data is transmitted at the scheduled data rate in the reverse link. With the schedules processed separately by the BSC (241) and BTS (213), the multi-user diversity of states on the reverse link of wireless communications is efficiently supported.

摘要： Methods and systems for providing uplink control in a wireless communication network are described herein. The wireless communication network includes at least one base station that is communicatively coupled to at least one mobile terminal. A method includes providing a dedicated random access channel to communicatively couple the base station and the mobile terminal; initiating the mobile terminal to select a random access signaling identification; generating a resource request at the at least one base station to receive uplink resource information from the mobile terminal; and receiving an initial access information request from the at least one mobile terminal to configure the base station connection.
