摘要:
A communication system and a method of communicating data. A first backhaul site can be dynamically selected from a plurality of backhaul sites that are each configured to wirelessly communicate with an access point. A controller can dynamically configure a transmission parameter used to communicate a first backhaul data stream between the access point and the first backhaul site. The first backhaul data stream can be derived from a source data stream and can be wirelessly communicated between the access point and the first backhaul site. A second backhaul site also can be selected. A second backhaul data stream also can be derived from the source data stream and wirelessly communicated between the access point and the second backhaul site. The first and second backhaul data streams can be combined.

A method (400) for establishing a first communication link between a communications network (105) and a network node (115) in accordance with a first wireless communications protocol. The method also can include evaluating a signal parameter for a signal transmitted between a station (110) and the network node. In response to the channel quality exceeding a threshold, the station can be signaled to establish a second communication link with the network node in accordance with a second wireless communications protocol. The network node can bridge communications between the station and the communications network.

A base station (105) includes a scheduler (220) to determine a location of a user terminal (110) within a cell (125) of a wireless system (100). The cell has a cell boundary (125). The scheduler (220) also determines a subcarrier frequency diverse resource allocation for a call on the user terminal (110) in response to the location of the user terminal (110) being within a predetermined distance from an edge of the cell boundary (125). The scheduler (220) further determines a subcarrier frequency selective resource allocation for the call on the user terminal (110) in response to the location of the user terminal (110) being beyond a predetermined distance from the edge of the cell boundary. The base station (105) also includes a transceiver (215) to transmit the call according to the subcarrier frequency diverse resource allocation and the subcarrier frequency selective resource allocation.
摘要:
A method and apparatus for establishing an active set of carriers from a plurality of available carriers for a wireless receiver. The active set of carriers can be determined from the plurality of available carriers for the wireless receiver. An indication of which carriers are in the active set can be sent to the wireless receiver, such as a receiver in a mobile communication device. The receiver or mobile communication device can monitor only those carriers that are listed in the active set of carriers.
摘要:
A base station (103) assigns a set of mobile stations (101) to a group wherein the group will share a set of radio resources. A shared control channel information element (501) is sent to the group of mobile stations (101) and provides a bitmap having fields for a control header (502), utilized resources (510), and first HARQ transmission assignments (530). HARQ subgroups may be defined to associate subgroups of mobile stations with specific HARQ transmission opportunities on the super-frame. The mobile stations (101) are assigned resources in a persistent manner in each long frame of a super-frame for which a first HARQ transmission opportunity is defined.

A wireless communication system where voice frames are transmitted in sub-frames, wherein multiple sub-frames constitute a single radio frame, at least one of the sub-frames not having a negative acknowledgement associated therewith, including at a radio access network (120), decoding a voice frame in sub-frame of a received radio frame, the sub-frame having a negative acknowledgement associated therewith, transmitting, from the radio access network, the voice frame in a sub-frame of an other radio frame, the sub-frame of the other radio frame not having an negative acknowledgement associated therewith.
摘要:
In a wireless communication system, a scheduler (100) determines (306) a first set of modulation and coding schemes (MCSs), each of which produces a maximum data rate for a first user, in accordance with available resource constraints (304) of the wireless communication system. The scheduler then forms, for each MCS of the first set, a second set of MCSs that produces the maximum data rate for a second user in accordance with a first residual resource (314) that remains when applying that MCS to the first user, thereby producing (316) a group of second sets of MCSs. After producing the group of second sets, the scheduler selects (324), from the first set and for the first user, a first optimal MCS corresponding to one of the group of second sets that allows a highest maximum data rate for the second user.
摘要:
A method for adjusting an OLT for power control, which is capable of closely tracking a low tFER. The OLT is adjusted based on frame quality indicator FQI and channel quality metrics. FQI and channel quality metrics are generated at the receiver of a base transceiver station after reception of a frame. If FQI equal to a logic zero was generated, the OLT is adjusted upwards using a first stepsize. If FQI equal to a logic one was generated for a certain amount of consecutive frames, the OLT is adjusted downwards using a second stepsize. The OLT is also fine-tuned during the intervals between the transitions caused by applying the first stepsize or second stepsize. The first and second stepsizes and the amount of consecutive frames of FQI=1 before OLT is adjusted downwards are determined adaptively according to time-varying channel conditions and received frame quality indicator.
