Description

Method and apparatus for mapping absolute power grant values

Technical Field

The present invention relates to wireless communications.

Background

In wireless communications, a set of allowable carrier amplitudes, power levels, or ratios of power levels may be assigned or "granted" to a transmitter. These values may be dynamic-as communication conditions change, authorization may change over time.

High Speed Packet Access (HSPA) is a collection of mobile telephony protocols that extends and improves the performance of existing mobile telephony protocols. The evolution of HSPA to support higher system throughput and performance has led to the introduction of 16QAM modulation in the uplink. One item that is needed to support Higher Order Modulation (HOM) is an enhanced pilot.

Many options have been disclosed to provide an enhanced pilot including increasing the power of the Dedicated Physical Control Channel (DPCCH), increasing the power of the enhanced dedicated physical control channel (E-DPCCH), and introducing a second DPCCH. In case of increasing the power of the DPCCH, scheduling problems occur when the enhanced absolute grant channel (E-AGCH) needs to jump suddenly and the operating point is close to the boundary of the power grant for BPSK and 16QAM modulation. The range of the power ratio needs to be extended if the power of the E-DPCCH is increased or a second DPCCH is added. An increase in the power ratio would require the E-AGCH to have more bits to cover a higher range or the step size in the absolute grant value of the E-AGCH must be increased.

Current solutions have system deficiencies and require careful consideration of the side effects of implementation. The desired option would be to increase the E-DPCCH power or add a second DPCCH, as this would require changing the E-DPCCH absolute grant value mapping table and should have minimal impact on the system.

The improved E-AGCH absolute grant value mapping table that exists today has some problems with how to update the table. One solution is to add additional indices to support the higher power ratio range required for 16 QAM. This change requires adding bits to the E-AGCH to cover the additional index value. Additional bits require changes in format and changes in coding. Thus, adding bits has a significant impact on the overall system structure.

One solution is to keep the E-AGCH form as it is, including the number of bits, the coding and the format. It is also desirable to maintain the current structure of the mapping table.

Disclosure of Invention

The present invention relates to wireless communications in which multiple power grant tables are used for different kinds of users. A plurality of power grant tables are stored in a wireless transmit/receive unit (WTRU). The WTRU receives a signal specifying which table will be used for the authorized power level during the communication.

Detailed Description

When referred to hereafter, the term "wireless transmit/receive unit (WTRU)" includes but is not limited to a User Equipment (UE), a mobile station, a fixed or mobile subscriber unit, a pager, a cellular telephone, a Personal Digital Assistant (PDA), a computer, or any other type of user equipment capable of operating in a wireless environment. When referred to hereafter, the terminology "base station" includes but is not limited to a node-B, a site controller, an Access Point (AP), or any other type of interfacing device capable of operating in a wireless environment.

Although the invention is described in the context of HSPA, it should not be construed that the invention is limited to the device scenario as an example.

A plurality of power grant tables are stored in the WTRU. In a first embodiment, an indexed offset value and an extended power grant table are disclosed. The plurality of power grant tables are derived from the extended table. For example, one of the tables may include power values that may be used for BPSK modulation, while another may include power values that may be used for 16QAM modulation. The offset value is used as a pointer to start indexing and is determined as part of the initial call setup between the two transceivers. Examples of two such transceivers are a WTRU and a node B that are setup by layer 3 signaling initiating a call. Once the WTRU knows the offset value, the WTRU also knows the portion of the extended grant table that will be used. This approach provides flexibility in that the extended table may be of any size and only the applicable portion of the table is used.

Referring to fig. 1, as an example, the absolute grant value table, which originally had 32 indices, is extended to 64 indices by appending 32 new entries. The existing table is shown in figure 1 at reference numeral 15 and includes indices 0 through 31 and the corresponding power ratio values in the column entitled "absolute grant values". The power ratio is shown as the square of the ratio of the E-DPCCH amplitude and the DPCCH amplitude. (the E-DPCCH is an enhanced dedicated physical control channel and the DPCCH is a dedicated physical control channel.) the symbols x4, x6, etc. in the entries of indices 24-31 indicate the number of E-DPCCH channels used for each entry. Index 24 is associated with 4E-DPCCH channels, index 25 is associated with 2, and so on.

The table designated by reference numeral 15 is defined in the third generation partnership project (3GPP) specification 25.212, release 7.5.0, section 4.10.1A. The 32 newly defined entries defining the second table are indicated with reference numeral 10 with indices 32 to 63.

The two tables in fig. 1 are applicable to both 16QAM modulation power ratio and BPSK modulation power ratio. For BPSK modulation, the index offset value is zero. This indicates that the table including index values from 0 to 31 should be used for BPSK. For 16QAM modulation, the index offset value is 32. This indicates that the table for 16QAM includes entries with index values from 32 to 63. If the modulation scheme is on the boundary line between BPSK and 16QAM, the index offset value will be 16. This indicates that the upper range (index 16-31) using BPSK and the lower range (index 32-47) of 16QAM results in a range of values from index number 16 to 47. To reduce the number of bits used to indicate the index offset value, a large table, such as one with a number of indices much greater than 64, would be partitioned into segments corresponding to the offset values. For example, if only BPSK and 16QAM are used, only 1 bit is needed to indicate the offset value to determine whether the top half 10 or the bottom half 15 of table 1 is used.

The index offset value may be used to specify (specific) the user power grant table based on the number of bits available in the initial setup. This approach provides flexibility with minimal changes in initial setup.

The offset values in the table may be sent to the WTRU in multiple ways. A first alternative is to transmit the value directly during setup. Direct transmission of the offset value may be set to accommodate any desired offset value.

A second alternative is to make the offset dependent on the slot offset of the AGCH relative to the top subframe boundary, which allows three possible values for the currently configured AGCH, namely 0, 1 or 2.

A third alternative is to make the offset value a function of the hybrid radio network temporary identifier (H-RNTI). The H-RNTI offset value may be pre-specified for different offset values.

A fourth alternative is to make the offset value dependent on the AGCH code or channel number being used for the AGCH. The AGCH code or channel number may be set up for different offset values. Only one code is currently present for the AGCH. Other convolutional codes with the same rate and puncturing may be used to represent different offsets. This requires the WTRU to perform multiple decoding cycles of AGCH data until the correct code is selected.

In a fifth alternative, the offset may be signalled by the Radio Access Network (RAN) by Radio Resource Control (RRC) signalling. The value of the offset and hence the grant table used may be either static (i.e. the same offset throughout the connection duration), semi-static (i.e. reconfigurable through L3 or L2 signalling) or dynamic (i.e. dynamically signalled to the node B for each new transport block).

The second embodiment uses separate power grant tables for different modulation types, e.g., BPSK and 16QAM modulation. In this case, no setting is required because the modulation type determines the table to be used. The applicable table is specified based on the modulation type. For example, for BPSK, a generic absolute grant value mapping may be used, while for 16QAM, a new grant table may be designed and preconfigured in or signaled to the WTRU. The general table that can be used for BPSK is defined using third generation partnership project (3GPP) specification 25.212, release 7.5.0, section 4.10.1 a.1. This approach has no impact on the current system, except for the addition of the table for 16 QAM.

A third embodiment uses an existing power grant table but with one or more larger intervals for the power ratio so that the power values cover BPSK and 16QAM modulation or other modulation types. This may be done by updating an existing authorization table with the new value. In particular, the two power grant tables used in the WTRU may be tables 16B and 16b.12 in third generation partnership project (3GPP) specification 25.212, release 7.5.0, section 4.10.1 a.1. The 3GPP specification 25.331, release 7.5.0, section 10.3.6.86a may also be used to define this table. The grant table, the interval, or both may be pre-configured in the WTRU. Alternatively, the table, the interval, or both may be signaled to the WTRU by RRC signaling upon establishment of the wireless communication. In the latter case, the table or the interval between power values can also be dynamically reconfigured over the lifetime of the connection by RRC signaling. The updated authorization table may be signaled to the WTRU by the RAN in one of the following ways: signaling the complete table; signaling the first and last power grant values; or to signal the interval between power values.
