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.

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:
A method for transmitting data in a multiple-input-multiple-output space-time coded communication using a mapping table mapping a plurality of symbols defining the communication to respective antennae from amongst a plurality of transmission antennae and to at least one other transmission resource. The mapping table may comprise Alamouti-coded primary segments and may also comprise secondary segments, comprising primary segments. The primary segments in the secondary segments may be defined in accordance to an to Alamouti based code pattern applied at the segment level to define a segment-level Alamouti based code.

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.

Methods and systems for providing uplink control in a wireless communication network are described herein. The wireless communication network includes at least one base station that is communicatively coupled to at least one mobile terminal. A method includes providing a dedicated random access channel to communicatively couple the base station and the mobile terminal; initiating the mobile terminal to select a random access signaling identification; generating a resource request at the at least one base station to receive uplink resource information from the mobile terminal; and receiving an initial access information request from the at least one mobile terminal to configure the base station connection.
