Description

200818757 IX. INSTRUCTIONS: [Technical field to which the invention pertains] s The following describes a large system relating to wireless communication, and more particularly to providing an elasticity for use in an orthogonal frequency division multiplexing (OFDM) system. The mechanism for guiding the model. [Prior Art] Wireless communication systems are widely deployed to provide various types of communication content, such as.曰, shell material, etc. A typical wireless communication system can be a multiple access system capable of supporting communication for multiple users of a disk by sharing available system resources (e.g., bandwidth, transmission power, ...). Examples of such multiple access systems may include code division multiple access (CDMA) systems, time division multiple access (TDMA) systems, frequency division multiple access (FDMA) systems, 3Gpp coffee systems, orthogonal frequency division multiplexing (0FDM), local frequency division multiplexing (lfdm), orthogonal frequency division multiple access (OFDMA) systems, and the like. In a wireless communication system, a Node B (or base station) can transmit data to a User Equipment (UE) on a downlink and/or receive a bedding from the UE on an Uplink. The downlink key (or forward link) refers to the five-link from the node b to the UE, and the uplink (or reverse link) refers to the communication link from the node B. Node B can also send control information (eg, system: source) to the UE. Similarly, the UE may send control information to Node B to support data transmission on the downlink or for other purposes. In the current state of the art, a multicast/broadcast transmission mode is used in which Node B can be transmitted to multiple 1s; operating within the system; The following will be practicable. The multi-side (pointing to multi-point) transmission operation will be operated as a single frequency network, and the higher enhanced data rate provided by the SFN transmission will be utilized. The SFN allows one or more neighboring cells to transmit the same content on the same subchannel during the downlink. However, when other non-data information also needs to be transmitted, the entire transmission may not be valid if the entire portion of the bandwidth is used for downlink i.

SC_FDMA has similar performance and generally the same overall complexity as the complexity of an OFDMA system. Signals have a lower peak-to-average power ratio (pApR) due to their inherent single-carrier structure. SC-FDMA has drawn great attention, especially in In uplink communication, where lower PAPR greatly benefits the mobile terminal in terms of transmission power efficiency. It is usually used for 3GPP Long Term Evolution (1^£) or Evolution 1; A working assumption of the mechanism.

The term "system 11 and" networks are often used interchangeably. CDMA systems may implement radio technologies such as Universal Terrestrial Radio Access (UTRA), cdma2000, etc. UTRA includes Wideband CDMA (W-CDMA) and low chip rate ( LCR) cdma2000 covers IS-2000, IS-95 and IS-856 standards.

UTRA, E-UTRA and GSM are Global Mobile Telecommunications Systems (UMTS) One part. Long Term Evolution (LTE) is the upcoming release of UMTS using E-UTRA. UTRA, E-UTRA, GSM, UTMS and LTE are described in the name from the ''Third Generation Partnership Project', (3GPP Among the documents of the organization, CDMA2000 is described in documents from an organization named "3rd Generation Partnership Project 2&quot; (3GPP2). For clarity, certain aspects of the techniques are described below for uplink transmissions in LTE, and 3GPP terminology is used in the extensive description below in 123918.doc -14-200818757. LTE utilizes orthogonal frequency division multiplexing (OFDM) on the downlink and single carrier frequency division multiplexing (SC-FDM) on the uplink. OFDM and SC-FDM divide the system into multiple (N) orthogonal subcarriers, which are also commonly referred to as tones, frequency bins, and the like. Each subcarrier can be modulated with data. In general, the modulation symbols are transmitted in the frequency domain with 0FDM and the modulation symbols are transmitted in the time domain with SC FDM^. For LTE, the spacing between adjacent subcarriers can be fixed, and the total number of subcarriers (N) can depend on the system bandwidth. In one design, N = 5i2 for a system bandwidth of 5 MHz, N = 1 〇 24 for a system bandwidth of 1 〇 MHz, and N = 2048 for a system bandwidth of 2 〇 MHz. In general, N can be any integer value. The LTE downlink transmission mechanism is split by a radio frame (e.g., a 1 无线电 radio frame). Each frame contains a model consisting of frequency (e.g., subcarrier) time (10), such as OFDM symbols. The radio frame is divided into a plurality of phase (4) .5 ms subframes (also known as subframes or time slots and are used interchangeably hereinafter). Each sub-frame contains a plurality of resource blocks, wherein each resource block is composed of one or more subcarriers and one or more 0 job symbols. - or multiple resource blocks may be used for transmission of data, control information, pilot signals (also referred to as reference signals), or any combination thereof. In order to achieve the most efficient use of SFN and cell-specific (e.g., unicast or multicast) mechanisms, the different methods described herein for multiplexing (4) and cell-specific pilot signals in the downlink are described.

This leads to an improved channel estimation zone that does not conflict with each other, especially at the cell edge. Figure 3 illustrates a cell-specific pilot transmission model for a subframe for transmission of a packet according to an example.

- sub-frame. In the exemplary guidance model, all of the tones for a symbol 3〇6 are allocated for transmission of navigation information. According to this example, when pilot transmissions of a maximum of six cells are completed using different tones during the -material period, the maximum of six cells will not collide. For example, use the tone 3〇4, 320, and 332 to transmit the cell navigation information; use the tone 〇, 322, and 334 to transmit the small W navigation information; use the tone (1), ^ and the coffee transmission cell 2 to guide the information; The tones 314, 326 and the transmission cell 3 guide information; the cell 4 guidance information is transmitted using the tones 316, 328, and 340; and the cell 5 navigation information is transmitted using the tones 318, 330, and 342. This model can be repeated in several symbol periods, for example, symbol periods 352 and 354. For the remaining tones in a sub-frame, the transmitter can transmit non-steering information. According to a state, cell 0 can transmit data or other information (eg, #非非信息) on the tone, where cells 2, 3, 4, and 5 transmit pilot signals. Therefore, the pilot tone experience - lower interference power spectral density (psD) and higher signal to noise ratio (SNR)' results in improved channel estimation. Visual system deployment specifies that fewer or more cells do not conflict. 4 illustrates a transmission model 〇〇 with SFN transmission for one subframe of downlink transmission according to an aspect, in which sfn data (eg, data transmitted using an SFN transmission mechanism) is in the same sub-signal On the box multiplex small 123918.doc -16- 200818757 zone specific pilot signal. According to an example, the transmission model is used for one of the sub-frames of the unsalted telecommunications frame consisting of a time period 460 times the bandwidth 462. In the factory, 所有 , type, all tones for a symbol 406 are assigned for transmission of navigation information. In this example, six cells that do not conflict with each other are shown. This is achieved by assigning a tone to each cell to transmit the navigation information. For example, the tones 404, 420, and 432 are used to transmit the cell navigation information; the tones 410, 422, and 434 are used to transmit the cell 1 navigation information; the tones 412, 424, and 436 are used to transmit the cell 2 navigation information; and the tone 414 is used. 426 and 438 transmit cell 3 navigation information; use celltones 416, 428, and 44 to transmit cell 4 navigation information; and use tone 418, 430, and 442 to transmit cell 5 navigation information. This model can be repeated in several symbol periods, for example, symbol periods 452 and 454. The remaining tones are designated for SFN transmission (shown in shaded in Figure 4). In a sad case, when SFN and cell-specific transmissions are multiplexed in the same subframe, the frequency reuse frame cannot be greater than 1 for cell-specific subframes that do not allow cells to collide with each other. This is due to the nature of the SFN transmission. Therefore, in this example 'cell 0 is not transportable, where cells 1, 2, 3, and 5 transmit 'induced 汛. Therefore, if the guidance from different cells is not allowed, the #引调音 is not available for SFN bedding for a given cell. However, 'cells can transmit such things as control information, assignments, null values (so that the frequency reuse model on the null tone is equivalent to the frequency reuse model on the data tone) or any other non-guided and non-SFN data. The transmission model for the cell may include transmission of pilot tones (e.g., tones 404, 420, and 432) that are repeated based on the number of bursts specified to avoid bursting. The transport model may further include a pass, 412, 414, 416, 418, 422 of the non-steering and non-SFN transmissions on the tone used by the other cells used to direct the transmission to the 918918.doc -17-200818757.

The remaining tones in the Sex Frame will be used for SFN transmission. lose. For example, tones 41 〇 424 , 426 ' Figure 5 shows a downlink (DL) transmission (τ χ) model 5 〇〇 (also known as SFN + CS transmission model) according to another aspect, in which SFN data is used ( For example, data transmitted using the SFN transmission mechanism) multiplexes cell-specific pilot signals on the same subframe. According to an example, the transmission model is used for one of the subframes of the radio frame consisting of time period 560 times the bandwidth 562. According to one aspect, all cells in the system are required to use tones designated for pilot transmission (shown as unicast), for null tones, or any combination thereof. According to the example transmission model, the resource blocks defined at subcarriers 5〇4, 52〇 and Μ] and used for symbols 506 552 and 554 are used for the transmission of all cells in the system. According to another aspect, a transmission model (not shown) can be used to assign a leading tone that does not conflict with the leading tones used by other cells,

For example, all of the pilot transmission tones of the numbers 5〇6, 552, and 554' are adjacent at 57G. In another aspect, the SFN+CS transmission model has all the tones that are used in the cell steering transmission and are adjacent in the frequency and clustered in the bandwidth of a sub-frame. For example, the symbols 5〇6, 552 and the pilot transmission tone are adjacent at 572. In another state in the state, an SFN+CS transmission model has a phase in the frequency that is designated for cell-specific steering transmission and is clustered at the bottom of a sub-frame.

Figure 6 shows the frame structure of the line link transmission model described under (4) during the period (4).妒媸处雄 ^ _ According to one aspect, using - or a plurality of model transmission - cell 敎 pilot signals selected from a group of DL transmission models. For example, during the time period 6_, four sub-frames, 6〇6, 6〇8, and 610 are transmitted. In the aspect, for subframe 604, the system may select a first model (eg, 'cell specific-reuse&gt; 1 as described in FIG. 3) or - second model (eg, as shown in FIG. 5). In the 606, 608, and 610 subframes, the system can use the first model or the mb, in the subframes where there is no transmission, for all the changes in the cell-specific + and the model described in the above.

The use of the SFN+CS transmission model can be periodic. In this case, the allocation of the subframe selected for use of the SFN + CS transmission model is periodically broadcasted in each cell. Once the DL transmission model is selected, all cells in the system will broadcast (e.g., transmit using a broadcast channel signal) information about the selected DL transmission model. This can be achieved by transmitting an indicator (one or more bits) and a subframe to the UE when the DL transmission model is to be used by the cell. The DL transmission model can be valid only for one subframe, where the indication must be retransmitted or broadcast before the selected DL TX model is used. Alternatively, one or more sub-frames may be assigned for use with a selected DL TX karma. In such situations, information about the assigned subframes to be used, for example, for the SFN+CS transmission model, will be broadcast by the cell to the UE. ', in the aspect' can use the identifier to identify the dl TX model described above. To reduce the consumption, only the TX model identifier and the specified subframe number are broadcast to the UE. The UE can then retrieve the exact processing associated with the τχ model from the memory and apply the method to process the received rounds for the designated subframe. • Referring to Figures 7-8, the method relates to a mechanism for indicating and broadcasting one of the SFN+CS transmission models for DL transmissions assigned as a subframe. However, for the sake of simplicity of explanation, the methods are shown and described as a series of acts, but it should be understood and understood that the methods are not in the order of the acts, as some acts may be in a different order depending upon the claimed subject matter. 123918.doc 200818757 is born and/or coincides with other actions shown and described herein. For example, those skilled in the art will understand and appreciate that a method can be alternatively represented as a series of related states or events, such as in a state diagram. Furthermore, it is not necessary that all illustrated acts be implemented in accordance with the claimed subject matter.

Turning specifically to Figure 7, Figure 7 illustrates an exemplary method for facilitating the broadcast of an indication of a selected DL TX model in a wireless communication system. Method 700 can facilitate transmitting an indication from a cell (eg, an enhanced node base station, eNode B, access point (AP), base station, or the like) to one or more terminals of a wireless communication network Machine equipment (eg, user equipment, UE, AT, or similar mechanism). The method begins at 7〇2, and the method determines if a transmission for the downlink transmission is used. In a bad case, the cell periodically determines whether the SFN enhanced data rate transmission content or whether it receives the SFN transmission from the beginning. In one aspect, the cell receives an indication from one of the systems to perform the SFN transmission and should occur. (4) The time position of the subframe when transmitting (4). If it is determined that (4) transmission is required, the method performs steps 704 706 and 708. Otherwise, at step 72, the method continues to use a preset transmission model 'for example' The first model described in 3. The SFN transmission model is determined in the 'cell' ^ A ^ ^ Awi and the evening transmission type at step 704, and the per-transmission model indication will be used for the reference signal (eg, The data and the symbols and tones of the sub-frames used to transmit the data using the SFN transmission mechanism.
