摘要:
Methods and devices are described herein for prioritizing a plurality of packets for potential transmission and in an iterative fashion: i) determining power requirements for control channel signalling associated with a highest priority packet not yet analyzed for resource assignment; and ii) assigning resources for said highest priority packet if sufficient power for control channel signalling is available and sufficient resources for said highest priority packet are available. A further method includes assigning a plurality of users to one of a plurality of signalling groups, wherein said plurality of users within said one of a plurality of groups use a first of a plurality of HARQ interlace offsets for their first respective HARQ transmissions.
摘要:
A method for execution by a mobile station (MS) in a mobile communications network, the method comprising: receiving a first MS identifier from the network during a ranging operation involving the MS; using the first MS identifier to extract the contents of at least one message received from the network during said ranging operation; using a second MS identifier, different from the first MS identifier, to extract the contents of at least one message received from the network after said ranging operation is complete. Also, a method for execution by the base station, comprising: outputting a first message destined for the MS, the first message including a first identifier for use by the MS during a ranging operation; determining that said ranging operation is complete; outputting a second message destined for the MS, the second message including a second identifier for use by the MS in subsequent communication with the network.
摘要:
To facilitate ranging between mobile terminals and a base station in a wireless communication network employing orthogonal frequency division multiplexing (OFDM) for uplink data communications, a periodic ranging channel for use by a mobile terminal is defined. The channel specifies a plurality N of blocks of sub-carrier frequencies of an OFDM frequency band which are non-contiguous within the OFDM frequency band. The channel also specifies a time slot within an OFDM subframe which spans one or more OFDM symbol periods. A ranging transmission is periodically sent as a spread signal across the specified N blocks of sub-carrier frequencies within the specified time slot. The duration of the ranging transmission may be less than a duration of the OFDM subframe. A notional grid of tiles representing time and frequency resources associated with the subframe may facilitate channel definition. A similar approach may be used to define an initial access channel for initial access transmissions.
摘要:
A method and system for a method of transmitting data within a signal frame. The method comprises inserting a first synchronization preamble into a first location within the signal frame and inserting a second synchronization preamble into a second location within the signal frame, wherein the first synchronization preamble conveys information indicative of the second location. The method further comprises issuing the signal frame towards a receiving device in a wireless communication environment.
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.

A method and system for achieving a link budget improvement in a diverse OFDM radio system by addressing the timing misalignment issue that can occur due to the differences in propagation time in signals between mobile stations and Radio Access Nodes. Timing misalignment is shared or split between the primary path to a primary Radio Access Node and a diverse path to a diverse Radio Access Node. The relative timing offsets between mobile stations are adjusted, the mobile stations are grouped into zones using a variety of different grouping techniques, and the transmission for each mobile station is scheduled, using one or more of a variety of scheduling techniques.

摘要:
Devices and methods are provided for using a mobile station to mitigate interference between wireless access points. A mobile station communicates interference mitigation data corresponding to a first and second set of radio resources between a first and second wireless access point (AP). The interference mitigation data is processed by the first wireless AP to resolve conflicts in the claiming, and subsequent assignment, of the first and second radio resource assignments to the mobile station.

A system and method are provided for mitigating interference between wireless access points (APs). A user equipment (UE) device uses a first set of radio resources to wirelessly communicate with a first AP and a second set of radio resources to wirelessly communicate with a second AP. The UE device then uses the first and second radio resources to communicate cooperation data between the first and second access points to mitigate interference thereinbetween.
