    摘要: A method and system are provided to perform channelization in a wireless communication network, wherein the wireless communication network including at least one base station that is communicatively coupled to at least one mobile terminal. A bandwidth of the wireless communication network is divided into a plurality of zones at the base station. Resource blocks are provided at the base station to receive data symbols transmitted in the wireless communication network. A plurality of resource blocks are combined at the base station to form a physical basic channel unit which are allocated to one of the plurality of zones at the base station. A permutation is performed on the physical basic channel unit to form a logical basic channel unit. A channel is provided to communicatively couple the base station and the mobile terminal so that the mobile terminal may send an access grant message and a user identification to the base station to transmit data in the logical basic channel unit.

    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.
