The method for eliminating paging interference includes: receiving, by a first base station, a paging parameter nB sent by a second base station; calculating, by the first base station according to the paging parameter nB of the second base station, a subframe for the second base station to send paging information and a paging frame to which the subframe belongs; obtaining, by the first base station, a set period; sending, by the first base station, paging information on the subframe in the paging frame within the set period; and stopping, by the first base station, information on the subframe in the paging frame within a next set period. Embodiments of the present invention are capable of reducing paging interference in a heterogeneous network. | 2013-08-08 |
20130201920 | GATEWAY APPARATUS AND COMMUNICATION METHOD - Provided is a gateway apparatus including a first communication unit that communicates with a base station in a first communication method, a second communication unit that communicates with a communication apparatus in a second communication method, an identification information holding unit that holds a correspondence between first identification information in the first communication method and second identification information in the second communication method of the communication apparatus, and a category information holding unit to share category information showing a characteristic of the communication apparatus with the communication apparatus. The first communication unit performs communication of the communication apparatus in accordance with the category information with the base station by using the first identification information of the communication apparatus. | 2013-08-08 |
20130201921 | Carrier Indication In a Bandwidth Aggregated Wireless Communications Systems - In this invention wireless communication of data between a user equipment and a base station including bandwidth aggregation of a plurality of component carriers, includes a first unit transmitting on a first component carrier a grant control signal the other unit specifying a second component carrier different to transmit the typically via a carrier indication field of 3 bits. The carrier indication field can be a one-to-one mapping to each possible second component carrier of a component carrier offset from an anchor carrier, which could be the first component carrier. | 2013-08-08 |
20130201922 | METHOD AND APPARATUS FOR ADMITTING A REQUEST FOR ALLOCATION OF WIRELESS CONNECTION RESOURCES IN A COMMUNICATION SYSTEM - A method and apparatus for admitting requests for allocation of bandwidth in a communication system is provided herein. During operation, available bandwidth is logically divided for use among commercial users and public-safety users, where the commercial users utilize a predefined portion of the bandwidth and the public-safety users utilize a public-safety portion of the bandwidth. When a public-safety bearer request is made, and available bandwidth does not exist within the public safety portion of the bandwidth, some bandwidth unoccupied by commercial users from commercial portion can be used to admit the bearer request. When commercial bandwidth is occupied by commercial users, lower priority commercial users can be preempted so that commercial bandwidth can be used to handle the bearer request. In a similar manner, the public-safety portion of available bandwidth can temporarily be used by commercial users. | 2013-08-08 |
