The disclosure relates to technology for a local control point in a communication system. The local control point may be an enterprise gateway configured as a gateway between radio access nodes and a core network that provides wireless communication for wireless devices that connect to the radio access nodes. The enterprise gateway may be connected to radio access nodes in a venue such as a retail shopping center, workplace, sports arena, public street, etc. The enterprise gateway may perform traffic flow management with respect to the local traffic in the venue. The enterprise gateway can make better decisions for traffic flow at the venue than a centralized point, such as a core network.

Localized traffic flow management in a wireless network

A scheduler capable of operating in an Orthogonal Frequency Division Multiplexing communication system schedules a control channel for a user equipment by determining a channel quality metric associated with the user equipment, calculating a target control channel element quality metric, determining a control channel element utilization rate, wherein the control channel element utilization rate a past rate of utilization of control channel elements, and selecting a control channel element aggregation level for the control channel based on the channel quality metric, the target control channel element quality metric, and the control channel element utilization rate. The scheduler then allocates control channel elements to the control channel based on the selected control channel element aggregation level. The scheduler further may steal power from one or more unused control channel elements and assign the stolen power to control channel elements assigned to the control channel.

Embodiments include methods and apparatus for granting scheduling requests in a wireless communications system that includes an eNB, a plurality of UEs, and a public safety system. The eNB receives multiple scheduling requests from multiple UEs, where each of the scheduling requests indicates that a corresponding UE is requesting uplink data transmission resources. The eNB determines a priority value for each of the scheduling requests based on multiple scoring criteria, resulting in a plurality of priority values associated with the scheduling requests. The eNB transmits one or more scheduling request grants to a subset of the UEs, where the subset includes one or more UEs that are associated with one or more scheduling requests having relatively high priority values. In an embodiment, the multiple scoring criteria include information associated with a public safety activity (e.g., a user role, a jurisdictional coverage area, an incident type, and/or an application type).

Granting scheduling requests in a wireless communication system

A MIMO base station is provided that includes a multi-channel transmitter having an input Fourier Transform Matrix (FTM) and an output FTM that are each coupled to an intervening signal processing section having multiple radio frequency (RF) amplifiers. A signal applied to an input port of the input FTM is distributed to all RF amplifiers of the transmitter by the input FTM and then is recombined by the output FTM such that the signal is routed to a single antenna of the multiple antennas of an antenna array. Thus, for both MIMO and non-MIMO transmissions, all RF amplifiers are used to amplify each input signal, but the non-MIMO transmission signal then is recombined such that only a single transmit antenna then is used to transmit the signal. The base station further provides antenna selection for a single antenna transmission and gain allocation among the multiple antennas for a MIMO transmission.

In an OFDM communication system, a mobile station provides a radio access network (RAN) a channel quality metric second order statistic, in one embodiment a signal to noise plus interference power ratio (SINR) second order statistic and in particular an SINR standard deviation and/or variance, along with a mean channel quality metric, that is, a mean SINR. By providing both a mean channel quality metric and a channel quality metric second order statistic, the communication system permits the RAN to create a more accurate fading profile of an associated air interface, and in particular a downlink of the air interface, thereby facilitating an improved scheduling decision over the prior art and assuring that a packet has a higher probability to go through a downlink channel without too many retransmissions.

Using conventional techniques, a common power control channel provides information used by mobile stations for power control operation of each mobile station. In accordance with the present invention, the common power control channel is also used to provide information used by the mobile stations for purposes other than the power control operation of each mobile station. In one embodiment, the information used for purposes other than power control operation comprises information instruction the mobile station to transition to an active state. In another embodiment, the information used for non-power control purposes is transmitted to mobile stations during periods in which the power control information is not being transmitted. Using a common power control channel in this manner substantially reduces the resources consumed by a mobile station while operating in a stand-by state.

A receiver () is provided receiving signals from differing base stations (BTSand BTS). The signal from BTSis encoded using a first rate convolutional encoder while the signal transmitted from BTSis encoded using a second rate convolutional encoder. Since the multiple base station links may result in a different number of symbols being received for each bit transmitted, the symbols received for each link cannot be simply combined. Therefore, in the preferred embodiment of the present invention, the resulting symbols are passed to multiple branch metric circuits (), where branch metrics (&#x3bc;) for the symbols are obtained. After the ibranch metrics for the base stations are computed, the branch metrics for each base station are passed to a combiner () where they are combined.
