System and Method for Searching for Grants and Assignments in a PDCCH

摘要

A method performed at a network component for indicating a number of grants in a transmission and a corresponding method performed at a station to limit a search for the grants to the number indicated in the transmission. In one embodiment, the transmission includes physical downlink control channel (PDCCH) information and modified cyclic redundancy check (CRC) information, the modified CRC information being generated from CRC information for the PDCCH information and a modifier representing a number of grants. The station determines the number of grants from the modified CRC information, performs a search for a first grant within the PDCCH information and terminates the search upon identifying the first grant, when the number of grants is the first number.

1. A method, comprising:
at a station:
receiving a transmission from a base station of a Long Term Evolution (LTE) network, the transmission including physical downlink control channel (PDCCH) information and modified cyclic redundancy check (CRC) information, the modified CRC information being generated from CRC information for the PDCCH information and a modifier representing a first number or a second number of grants, the first number indicating a first grant type only or a second grant type only is included in the PDCCH information, the second number indicating the first and second grant types are included in the PDCCH information;determining the number of grants from the modified CRC information;performing a search for a first grant within the PDCCH information; andterminating the search upon identifying the first grant, when the number of grants is the first number.
