Methods and apparatus for formatting headers for data packets within a communication frame for use in a wireless communication system are presented. Formatting headers includes determining the size of a wireless communication frame, and formatting the payloads and associated headers within the communication frame according to the determined size. This formatting includes placing headers at the beginning of the frame before the data packets corresponding to the headers to optimize processing of the headers at a receiver. Formatting may also include formatting the headers according to a first format within the frame when the determined frame size is below a predetermined size to optimize the size of the headers, and formatting according to a second format within the frame when the size of the data packet is equal to or greater than the predetermined size to optimize processing for frames having large data packets.

Techniques for estimating and reporting channel quality indicator (CQI) are disclosed. Neighboring base stations may cause strong interference to one another and may be allocated different resources, e.g., different subframes. A USE may observe different levels of interference on different resources. In an aspect, the UE may determine a CQI for resources allocated to a base station and having reduced or no interference from at least one interfering base station. In another aspect, the UE may determine multiple CQI for resources of different types and associated with different interference levels. For example, the UE may determine a first CQI based on at least one first subframe allocated to the base station and having reduced or no interference from the interfering base station(s). The UE may determine a second CQI based on at least one second subframe allocated to the interfering base station(s).

Local IP access is provided in a wireless network to facilitate access to one or more local services. In some implementations, different IP interfaces are used for accessing different services (e.g., local services and operator network services). A list that maps packet destinations to IP interfaces may be employed to determine which IP interface is to be used for sending a given packet. In some implementations an access point provides a proxy function (e.g., a proxy ARP function) for an access terminal. In some implementations an access point provides an agent function (e.g., a DHCP function) for an access terminal. NAT operations may be performed at an access point to enable the access terminal to access local services. In some aspects, an access point may determine whether to send a packet from an access terminal via a protocol tunnel based on the destination of the packet.

Local IP access paging schemes facilitate paging of an access terminal when packets destined for the access terminal are received via local IP access. In some implementations, a local entity acquires information that enables local paging of the access terminal by sniffing messages passing through the local entity. In some implementations, a local entity sends a packet or message to cause the core network to page an access terminal when a local IP access packet destined for the access terminal arrives at the local entity.
摘要:
A method, comprising: identifying a pair of base stations in a wireless communication system, the pair of base stations comprising a first base station and a second base station; determining if the first base station and the second base station are neighboring base stations; assigning the first base station and the second base station to a same reserved subset of frequencies; and in response to the first base station and the second base station being neighboring base stations, assigning full power transmission to the first base station and reduced power transmission to the second base station as well as a corresponding apparatus.

A method, apparatuses and computer program are provided that determine a different base station from a serving home evolved Node B (HeNB) for utilizing assistance information in determining a position; and receive assistance information related to the different base station from the serving HeNB or a positioning server. This is done for positioning of the serving HeNB.

A method comprising: receiving information indicative of a frequency reuse scheme to be employed over a reserved portion of a frequency band assigned to a first base station of a plurality of base stations, wherein the reserved portion of the frequency band is a fraction of a frequency spectrum, the fraction of the frequency spectrum being determined based on a signalling traffic load for the first base station of the plurality of base stations and a position of the first base station of the plurality of base stations relative to a second base station of the plurality of base stations; and transmitting signalling information over the reserved portion of the frequency band as well as a corresponding apparatus.
