    摘要： Methods, base stations and access terminals for uplink signalling are provided. Resource request channel characteristics such as location in time-frequency, sequence, time slot, are assigned to each access terminal to distinguish their resource requests from the resource requests of other access terminals. Access terminals make requests using a resource request on a resource request channel having the assigned characteristics. The base station can then determine which access terminal transmitted 0 the resource request based on the resource request channel characteristics of the resource request channel upon which the resource>request was received. The base station then transmits a response to the request which may for example be a new resource allocation, a default allocation or a renewal of a previous allocation.

    摘要： In order to minimize the control signaling overhead associated with transmitting CQI data from mobile stations to base stations in wireless communication networks supporting MU-MIMO, the CQI during MU-MIMO operation is estimated based on SU-MIMO CQI data, mobile station geometry data, and mobile station PMI (Precoding Matrix Index) data. More particularly, the base station maintains and updates a knowledge pool that correlates geometry data and learned impact of interfering precoder data to degradation of CQI values responsive to switching from SU-MIMO operation to MU-MIMO operations. Then, when the base station switches from SU-MIMO operation to MU-MIMO operation, it consults the knowledge pool to predict the degradation in CQI and subtracts them from the known, pre-switching SU-MIMO CQI feedback data for each relevant mobile station to predict the post-switching MU-MIMO CQIs for that mobile station.

    摘要： A method of optimizing downlink communications between a base station and mobile stations in a wireless communication system involves: identifying users that have a modulation control scheme (MCS) power value greater than a reference power value as high power users; for each of the high power users, calculating a power difference being a difference between a geometry value associated with each of the high power users and a reference geometry value associated with the reference power value respectively; summing the power differences in a power pool; identifying users that have an MCS power value below the reference power value as low power users; associating increased geometry values with at least some of the low power users while depleting the power pool by corresponding amounts until the power pool is depleted; and determining new MCSs for at least some of the low power users based on the increased geometry values.

    摘要： A method and system are provided having an uplink control structure and a pilot signal having minimal signal overhead for providing channel estimation and data demodulation in a wireless communication network. The uplink control structures enable mobile terminals to communicate with corresponding base stations to perform various functions including obtaining initial system access, submitting a bandwidth request, triggering a continuation of negotiated service, or providing a proposed allocation re-configuration header. A dedicated random access channel is provided to communicatively couple the base station and the mobile terminal so that the mobile terminal can select a random access signaling identification. A resource request is received at the base station to uplink resource information from the mobile terminal and an initial access information request is received from the mobile terminal to configure the base station connection. Pilot signals with varying density configurations are provided to include low density symbol patterns for multiple contiguous resource blocks and high density symbol patterns for single resource blocks.

    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.
