Patent number: 9100844Abstract: A method and apparatus of selecting which of a plurality of receiver chains of a mobile unit to receive wireless signals, is disclosed. One method includes measuring a first receive signal quality while all of the plurality of receiver chains are receiving wireless signals, and measuring a second receive signal quality while a subset of the plurality of receiver chains are receiving wireless signals. The subset of the plurality of receiver chains are selected to receive wireless signal unless the first receive signal quality is a threshold better than the second receive signal quality. If the first receive signal quality is a threshold better than the second receive signal quality then all the plurality of receiver chains are selected to receive wireless signals.Type: GrantFiled: July 22, 2013Date of Patent: August 4, 2015Assignee: Broadcom CorporationInventors: Louay Jalloul, Sam P.

Publication number: 20130003642Abstract: A method and apparatus of scheduling and transmitting uplink packets within uplink sub-frames of a wireless system is disclosed. The method includes determining a size of a standard data unit, and determining if the standard data unit can be transmitted within a single sub-channel of an uplink frame by comparing the size of the standard data unit with a number of bits that can be transmitted within the uplink frame as determined by an uplink quality. If the standard data unit is too large to be transmitted within a single sub-channel of an uplink frame, then the standard data unit is divided into sub-data units. The sub-data units are transmitted over multiple uplink frames.Type: ApplicationFiled: September 7, 2012Publication date: January 3, 2013Applicant: Broadcom CorporationInventors: Anuj Puri, Manish Airy, Amar Prakash Azad, Arogyaswami Paulraj

Publication number: 20120201160Abstract: Methods assigning mobile users in a half-frequency division duplex (HFDD) system to first and second UL groups of an uplink (UL) sub-frame, and to first and second UL groups of a downlink (DL) sub-frame, where the UL sub-frame has a first carrier frequency and the DL sub-frame has a second carrier frequency, are disclosed. One method includes determining a type of data, a receive CINR (carrier interference plus noise ratio), and a Doppler frequency parameter, for a plurality of mobile users. The mobile users to are assigned to the first UL group, second UL group, first DL group and second DL group based on time durations of the first UL group, second UL group, first DL group and second DL group, and at least one parameter of the determined parameters of the mobile users.Type: ApplicationFiled: February 8, 2012Publication date: August 9, 2012Applicant: Broadcom CorporationInventors: Louay Jalloul, Harold Artes, Anuj Puri

Patent number: 8208433Abstract: A method and apparatus i.e. Base Station for allocating resources in a wireless communication system is provided. The method includes generating a plurality of first groups of allocation units based on one or more of a plurality of Modulation and Coding Schemes (MCSs) and traffic characteristics in the wireless communication system. The method further includes generating a second group of slots including resource allocation information for mapping first groups of allocation units to Mobile Stations (MSs) based on MCSs and traffic characteristics associated with first groups of allocation units and the MSs. Thereafter, the method persistently allocates each first group of allocation units to the MSs based on one or more of the resource allocation information and a communication state associated with each MS. Further, the method also identifies if each MS has succeeded in decoding the persistent resource allocation sent in the second group of slots.Type: GrantFiled: February 17, 2009Date of Patent: June 26, 2012Assignee: Broadcom CorporationInventors: Soumen Chakraborty, Sindhu Verma, Manish Airy, Anuj Puri
